This invention relates to structural parts such as trusses and strength members for use in building frames of buildings and similar constructions. It is a primary object of the invention to provide a novel arrangement of. parts so that a series of constructlon members may be produced that are capable of use in a variety of ways so that they may be attached together to form a number of different constr uctions of various shapes and sizes. It is intended that the invention is capable of use either for the making of construction members for use in the construction. of large buildings, barns, hangars or bridges; or that it be used to provide a miniature form of building members for use in an educational and instructive manner.

In accordance with my invention, fabricated trusses which are preferably constructed of metal stampings riveted together are provided so that they maybe interchangeably attached together in a varletyof ways. To this end the sides of the trusses are provided with a series of attaching holes suitably spaced apart in a unifornrmanner, and su1tably arranged along the side of the truss so that the trusses may be attached together with apexes of adjacent trusses at a common point.

Each truss is preferably made with its sides formed of a pair of angle pieces riveted together, and for use in large trusses for the construction of large buildings it has been found that an angle section of increased vertical height and a thinner section than usual, provided with an outwardly pro ect 1ng flange at the lower end of the angle piece gives strength to the truss far in excess of that which can be produced by the use of common angle irons of present day construction oi the; same weight.

The three forms of trusses, by means of which a large number of buildings of any sort may be constructed, are of triangular form,

each truss having an angle which is an even multiple of 22%", that is, the trusses have angles of 22 67 90 and 135. An important feature of this truss form, in accordance with this invention, is the fact that each truss has a side with a length corresponding to the side of another truss. In the pre- 135, which is termed the a truss. The short side of the Z) truss has a length which is equal to the side of the 67 truss opposite to the 67 angle. This 67 truss will be termed the 0 truss.

The various trusses may be constructed of heavy structural steel for use in the construction of large bulldings, the various trusses all being provided with the attaching bolts or rivet holes so that the trusses can be pro duced in quantity lots and at a minimum expense in a few standard shapes and sizes. The buildings may be readily designed so that they may use the standard trusses manufactured by combining these trusses to build other trusses of larger form and by combining these trusses with other structural members such as angles, pivot members, guy wire fittings, columns, channels, girts, purlins and fish plates. p a

The various accessory members to be used with the trusses, such as the members just mentioned, are all fabricated to the proper standard shape selected so that they may be interchangeably connected in a variety of manners and any one part may be attached to almost any other part in almost any manner desired. The spacing ofrivet holes along the sides of the members, such as the angles, pivot members, channels, etc, is a uniform arrangement so that the rivet holes are spaced a uniform distance apart and the series of holes are so located from the ends of the various members that the members may be attached together with their ends at a common point.

The various structural trusses and members may be made in a small form of miniature size so that they may be used for educational and instrucive purposes and for the construction of small models of buildings. These miniature members are preferably made of thin sheet metal, and are of substantially the same general arrangement as in the large structural steel members. It is intended that the miniature trusses shall be aswhich will be more fully set forth in the following description and inthe drawings, reference is made to the various figures of the drawings in which: v

Referring more. particularly to the drawings by reference numerals, 1 indlcates a truss of triangular form which is used in conyunction with the trusses 2 and 3, as shown in Fig.

3, it being intended that the various trusses shall be fabricated to the form shown and produced in quantity and provided with means so that they may be attached together in a variety of different ways.

The truss 1 is composed of the sides 4, 5 and 6, each of which is composed of a pair of angle pieces 7 and 8 (see Fig. 5), which are riveted together by the rivets 9. The angle pieces 7 and 8 are formed as shown with a main back part 10, which is provided with the upper outwardly projecting side 11, and the lower small flange 12. The height of the back 10 is considerably in excess of the extent of the side 11, and the shape of the angle piece as a whole is considerably thinner and deeper than the standard form angle iron at present in use in structural steel work. The form shown has an immense advantage over the present shape angle iron, for use in the fabricated trusses to be more fully described, since the same strength may be produced in a truss at much less weight using the new and preferred form of angle section. In this preferred form of angle section, see Fig. 5, the thickness of metal is for a 5x2 section.

In the truss 1 the angle between the sides 5 and 6 is 135, and the angle between the side 5 and 4, and between 5 and 6 is 22 The length of the sides 5 and 6 which are equal, is equal to the length of the side 13 of a 45 angle truss, which is fabricated in the same manner as described. for the truss 1., which will be termed the 0. truss. The 45 angle truss will be termed the b truss. By placing the two trusses together and attaching them together with the side 13 of the b truss against the side 6 of the a truss. a truss willbe formed of larger size than either of them and one which is itself a triangle. The two sides, 14 and 15 of the b truss, are of course of equal length, and this length corresponds to that of side 16 of the third truss 3, which will be termed the 0 truss. The side 14 is constructed of material of the same thickness as that forming the angle pieces of the side 15, but the depth of the angle pieces forming the side 1 1- is greater than that employed in the other angle pieces. This makes he side 1% of the b truss of heavier formation than other sides of other trusses. Thus. when two I) trusses are placed together the heavy side 14; is intended to be the side which is unattached to other structural members. Where the side 15 is to be attached to other structural members it is, of course. rigidified by reason of this attachment. The angle between the side 16 of the hypotenuse 1'? of the a truss is 22 and the 0 truss like the 7) truss is a right-angled triangle. Since all of the trusses have acute angles of an even multiple of 22 that is, either 22 45, 67 90 or 135. the various trusses may be assembled together in avariety of ways with their apexes at a common point and produce useful trusses of desirable shapes.

The various trusses are provided with fish plates 19, which are placed between the two angle pieces 7 and 8, the various parts being held together by the rivets 9. The various llsh plates are attached together by means of the angle braces 20 to rigidity the truss as a whole, it being desirable that the plate at the center of the longest side of a truss should be connected to a fish plate in the corner of the truss opposite to that side. These braces 20 are fabricated together on opposite sides of the lish plates in pairs by means of rivets 21.

The sides 11 of the angle pieces 7 and 8 are provided with a series of attaching bolt or rivet holes 22, to term a double series of holes along each side of a truss. The holes in each of these series are spaced apart by a distance .9 uniitorn'ily. The length of sides i l, 15 and 16 of the Z) and c trusses are preferably so chosen as to be an even multiple of this distance a, so that the rivet holes will not only be evenly spaced apart but will be spaced at the same spacing distance away from each end of the side of the truss, or in other words away from an apex. With such an arrangement, it is possible to assemble the I) and 0 trusses together in a reversible manner, that is, the 22% angle apex of the a truss may just as readily be placed at the corner of the b truss. That two sides of any truss taken through its plane of symmetry will, of course, be identical. The short side 18 oi the c truss is provided with the rivet holes 22 so positioned that the spacing of the first hole from the 90 corner of the truss corresponds to the spacing distance .9. This is done so that the 90 corners of the trusses may be placed in any 90 space provided by other members and so that with the attaching holes of the mating members in proper agreement, they will e2;- actly lit in the corners. The holes provided in the sides of the a truss and those provided in the hypotenuse oi the b and c trusses are centrally positioned along the length of these sides.

It desirable that the size of the trusses be made such that the distance from an end hole of the attaching series of holes from an end of its side of the truss be approximately equal to the spacing distance 8 to as great an extent as possible in all the truss sides so that trusses may be joined with their apenes in substantial agreement. It is, oi course, impossible to have all the sides of all the trusses provided with their attaching holes the exact distance .9 away :trom the ends of all the sides. However, this is not especially essential since the trusses are assembled together usually either with their sides in the relations shown in Fig. 3 or with such a relation but with one or more of the trusses reversed end tor end or with trusses attath d to other trusses of the same shape. ll ith the spziicing holes arranged centrally of the long sides of the trusses, and also centrally of the sides 5 and 6 of the a truss, any side of a at a common point or apex, as the ends of this:

truss are of such pointed nature that they would have little strength and consequently it is desirable that these trusses should be shaped as shown in Fig. 3 with their sharp apexes cut oil, so that some rigidity may be attained in the apexes by maintaining the heavy section oi the angle pieces practically to the end of the truss. It will be obvious that since sides 6 and 13 ot' the a and Z) trusses are equal, the cut oil end of the a truss will".

coincide with the short side Oil the Z) truss.

It will now be clear that the various trusses shown in Fi 3 may be assembled together by riveting together the sides of the various fabricated trusses to form a large truss, indi- U cated generally at 23 in Fig. 1. This large truss as will be seen is composed of the a truss, the two Z) trusses and the top .0 truss on each side of the building. Each truss 23 forms a support in one plane for the building and amt.

number of these trusses 23 are used to form a large building, part of which is shown in Fig. 2. The trusses may be assembled in a variety of manners to form buildings of: various sorts and of various shapes and sizes, for example,

Fig. 6 shows a construction of a hangar ior airplane use which is formed of vertical sides constructed of a series of c trusses, and the root oi which is constructed of a series of a trusses attarhcd together by a pivot fittingp An extension indicated generally at 2% shows a root truss formed ot a and. 7) trusses.

In conjunction with the various structural trusses a number of accessory parts are utilized in the making of any structure. The building shown in Fig. l is supported by a series of vertical columns 25, which are of ti section, as shown in Fig. 11. These columns are drilled at their ends with a series of at taching bolt holes 25 so that they may be assembled in position and so that the spacing of the holes 26 from the ends of columns coincide with the spacing 3 employed in the trusses. The columns 25 are attached to gether by a series of girts 27 of channel section as shown in F 10. These channels may be made of one or two main sizes so that they maybe either used as girts or may be used as purlins as indicated at 28 in Fig. l, and at 29 in Fig. 6. T he purlins 28 or 29 support the roof or cover of the structure as indicated at 30. The channels 27 are provided with a series of attaching holes 31, which are spaced a distance 6 from the end of the channel. This distance 6 corresponds substantially with the distance t shown in Fig. 4: between a hole 22 and the medial line of the truss side. These channels 27 may also be used for columns, girders, or may be employed in a variety of manners.

Small angle fittings 32 are used to interbrace the columns and the truss sides. These angle fittings are formed of angle pieces 33 V and 34, which are attached in pairs to a fish wise spaced a distance .9 from this corner so that these fittings may be inserted in any 90 corner with the assurance that the rivet holes will match up with the holes in the pieces forming the corner. The length of each of the short sides of the'angle fitting are preferably also an even multiple of the distance 8.

The shape of the section of the pieces 33 and 34 may be either in accordance with the usual angle section at present in use in structural steel work, or may coincide with the section shown in Fig. 5, in which the thickness of :the metal is considerably less than standard angle sizes.

Inorder'to attach trusses to other members or other trusses, particularly where the angle made by the side of a truss does not or;-

actly fit in the position that it is intended to be placed, the truss isattached toa pivot piece 38, whichis formed of a pair of angle pieces 7 39 and 40 riveted together and to a series of plates 41, which extend downwardly and form the hinge end 42. This hinge end 42 is attached by pin 43 to a hinge end 44, which is constructed of a series of plates riveted together to form a fabricated anchor arrangement as indicated at 45. Means are provided for attaching the fabricated arrangement 45 to a fixed support by holes 46. A pair of pivot fittings 38 may be attached toget-her by joining their two pivot ends 42 toother members and form a support.

gether by a pin 43. The sides of the angles 39 and 40 are provided with the holes 47, spaced thecustomary distance .9 apart so that these holes 47 may be attached to the trusses or to The two r pivot members shown at 48 in Fig. 6 are used to attach together the two a trusses forming theroof truss of the structure. The pivot pieces 49 and 50 are used to attach the building to the point of attachment at the ground.

.' 25. zo'ntal plane passing through the lower sides The various trusses 23 shown in Figs. 1 and 2, and the varioustrusses shown in Fig. 6, are attached together by means of guy wire cables 51 which are crossed as shown in Fig. 2 and extend in a vertical plane above the column The second series of cables lies in a 1101i of the trusses, and attaching the various trusses together in fixed relation. The two obtuse angles of the two a trusses of Fig. 6

are attached together by guy wire cable 51 as indicated. Each of these cables 51 is attached by means of turnbuckle 52, clamps 53 and cable 54 to an end fitting of substantially U shape 55, which is attached by means of a bolt 56 to one of the holes in a truss or other structural part.

It is intended that the various trusses and the various accessory parts will be made in large quantities of a standard size and a standard shape. These trusses may be then assembled together in various relations to form large structures or frames of any sort. These frames may be salvaged in case the building is to be torn down or may be used in the reconstruction of a building by merely burning out the rivets. The trusses being of standard sizes and shapes may be used many times and in a knocked down manner if desired. It is intended that the angle pieces shown in Fig. 5 will be made in the form of a stamping, one operation being all that is necessary to cut the holes in the back and the sides of the angle pieces and then immediately bend up the two ends of the angle pieces. It is intended that the material used for the construction of large buildings will be structural steel of a thickness of about where the section shown in Fig. 5 is employed. This section corresponds to a length bf about 20 to 30 ft. of a truss side.

My invention is susceptible of use in the construction of educational and instructive structural members, which may be assen'ibled in the same manner employed with the structural steel members just described. It is contemplated that a miniature set of a large number of various trusses with a number of accessory parts, such as the angle fittings, pivot members, channel braces or columns, and guy wire clamps and fittings should be supplied so that they may be used to make various model buildings or structures. T hcse miniature trusses are of small size, say about a foot long, and the weight they are employed to brace is comparatively small as compared with the regular structural steel. They can therefore be made of thin sheet metal in the form of stampings and to this end a blank for such stampings is shown in Fig. 15. This blank designated as 57 is intended to be cut and stamped and have its edges bent up in a single operation. the same operation also cutting the attaching holes in the faces and bent up sides of the blank. The blank 57 is bent along the dotted lines 58 and provided with attaching holes in sides 59 and 60 of the truss blank. The material is cut away from the openings 61 and the metal bent along the dotted line 62 so as to form a rigidifying brace from the center of the hypotenuse to the corner of the blank. The four holes 63 stamped in the piece and the rivets (34 (see Fig. 16) form means to attach two stampings together, back to back, to form a fabricated miniature truss.

The number of rivets necessary to attach the pairs of blanks together to form a truss lili] in the miniature construction is small, and the blanks are therefore stamped with depressions 65, which imitate rivet heads and which will be edective in increasing the strength of the truss by the bulge which is produced. Fig. 17 shows the construction of such an imitation rivet at 65.

Fig. 14; shows three trusses, A, B and C, which correspond to the trusses a, b and 0 previously described. The truss A. built of thin sheet metal stampings has angles of 22 fill/ and 135, the B truss is a angle truss and the C truss is a il rightangled triangle. All three of these trusses are exactly triangular in section as shown, although it desired the sharp apeires may be cut away as shown and described in Fig. 3 for the heavy structural steel trusses. The spacing; of the rivet holes, by means of which various trusses are attached together, correspond essentially to the spacing described for the structural steel trusses, so that the various trusses may be assembled together in various manners. The distance S is uniterm in the three A, B and C trusses and the attaching holes are spaced from the apeXes ot the trusses in such a way as already de scribed in detail so that the various trusses may be variously assembled together or assembled with a similar truss in any manner.

Fig. 18 shows a blank, two of which are adapted to be attached together after being bent and stamped so that an angle fitting is provided which corresponds to the other angle fitting shown in Fig. 12. The uniform spacing of attaching holes in the angle litting 66 shown in Fig. 18 still applies, this distance being indicated as S.

Fig. 19 shows the standard channels which are supplied with the various trusses, these channels being likewise made of stamped sheet metal and provided with attachin holes in their ends so that they may be as sembled in various manners. lwo channels, for instance, may be attached together as shown in 20 by means of the attaching bolts and nuts 67 and 68, which are supplied in quantity for the assembly of thevarious trusses and strength members.

lit desired, a number of wire fittings and turnbucliles corresponding to the turnbuckles and fittings shown in Fig. 13, but of miniature size, shall be supplied with the trusses shown '.1 Fig. l l, and in addition accessories such as pivot members, etc., corresponding to those shown in Figs. 7 and 8, may also be used in the construction of miniature buildings for educational purposes or as models of larger buildings.
