WESLEY MARVIN HUBBARD, OF CLEVELAND, NEW YORK.

MOLD.

To all whom, it may concern.-

Be it known that I, WESLEY MARVIN HUB- BARD, a citizen of the United States, residing at Cleveland, in the county of Oswego and State of New York, have invented certain new and useful Improvements in Molds, of which the following is a specification.

This invention relates to concrete articlessuch as sarcophagi, burial-vaults, and the likebut the same is not necessarily limited to this particular use.

The primary object is to provide a novel and comparatively simple structure that will effectively hold its shape during the molding operation and which can be readily collapsed and dismembered in order to disengage it from the molded article without injury thereto.

A further object is to provide means for positively moving certain of the parts without shock or jar out of engagement with the article, thus eliminating the danger of checking, cracking, or breaking such article.

Still another and important object is to provide a simple mold which maybe employed for manufacturing both the body and cover of the vault or other box without materially altering any of the parts.

An embodiment of the invention that is at present considered preferable is disclosed in the accompanying drawings, wherein Figure l is a top plan view of the mold when'set up. Fig. 2 is a longitudinal sectional view through the same. Fig. 3 is a crosssectional View. Fig. 4 is a top plan view. showing the core collapsed. Fig. 5 isa sectional view through the core, taken substantially on the line 5 5 of Fig. 1. Fig. 6 is a perspective view of one of the corner-pieces. Fig. 7 is a bottom plan view of the same. Fig. 8 is a perspective view showing one of the open corners of the mold with the cornerpiece removed. 9 is a cross-sectional view showing the relation of parts when a cover is formed. Fig.10 is a perspective view of certain of the filler-bars.

Similar reference-numerals designate corresponding parts in all the figures of the drawings.

In the embodiment illustrated a pallet 11 is employed on which the mold proper is supported. This mold includes outer angularlydisposed side and end walls 12 and 13, the latter being provided in their inner sides with seats 14, receiving the ends of the former. The side walls are provided with longitudi- Specification of Letters Patent.

nally-projecting stud-bolts 15, that pass through the ends of the end walls 13 and receive holding-nuts 16. It will thus be apparent that the outer walls can be rigidly, but detachably, secured together, and when set up and placed upon the pallet they pref erably terminate short of the edges thereof. A core is also provided, said core being in the form of a sectional boxing having side walls 17 and end walls 18, each end wall being rigidly secured to one of the side walls and terlinks 21, pivoted at their ends to said sections,

and thus permitting the swinging of the sec tions toward and from each other. A steady positive movement of the sections toward each other is secured by a connection consisting of draft-bars 22, the outer ends of which are connected, as shown at 28, to the diagonally opposite closed corners of the coresections, the inner ends of the bars being connected by a turnbuckle 24, having a threaded engagement 25 with said inner ends.

For the purpose of completing the side walls of the core corner-pieces 26 are employed, which fill the open corners and constitute, in effect, continuations of the walls, these corner-pieces being carried by angular reinforcing-plates 27, that overlap the walls 17 and 18 and are detachably secured thereto by screws or other fasteners 28. Bottom plates 29 are carried by the reinforcingplates 27 and have depending portions 30, that close the ends of the space between the core-sections. This, it is thought, will be clear by reference to Figs. 5, 7, and 8. The remainder of the space between the bottom sections 19 of the core is filled by a strip comprising sections 31, the opposite edges of which are beveled to correspond to the beveled edges of the sections 19, the outer ends of the sections 31 being engaged beneath the bottom plates 29 of the corner-pieces and their inner ends being disposed beneath a IIO tain the intermediate portions of the stripsect'ions 31 in position.

For the purpose of properly positioning and supporting the core between the outer 5 walls cross-bars 35 are employed which are pivotally and detachably connected, as shown at 36, to the side walls 17 of the core and rest upon the upper edges' of the outer side walls 12. These cross-bars are preferably disposed directly over the swinging links 21,

and the ivot-aXes of said links are preferably conmcident with the axes of the fasteners 36. The ends of the cross-bars 35 project beyond the outer side walls, and through the same are passed tie-bolts 37, that also pass through the pallet 11, thus clamping all the parts securely against relative movement 1 upon said pallet.

In molding the body of a sarcophagus, vault, or box the parts are placed in the positions and relations illustrated in Figs. 1, 2, and 3, and itwill be observed by reference to Figs. 2 and 3 that inasmuch as the core is of less depth than the outer walls the bottom thereof is supported above the pallet. The material is then poured into the space between the side walls and filling the same and the space between the bottom and pallet will be formed into the article. While plain flat side walls are shown in order to avoid confusion, it will be evident that the config- I uration thereof may be altered to form pleasing and ornamental designs. After filling the mold the top is smoothed off, and when the water has run out, so that the inner mold will not float, the cross-bars 35 are detached and a V-shaped groove is formed in the top edge of the article, as shown in Figs. 2 and 3. The cross-bars are then replaced and the corner-pieces, as well as the strips 31, are detached, this being readily accomplished by removing the fasteners, which will permit the said corner-pieces and strips to be taken out. The turnbuckle 24 is then tightened slightly to eliminate the binding engagement between the core and the article, and thereby avoid hair-cracks in the latter by permitting the cement to contract without I When the concrete is suffi-:

interference. ciently hardened, the turnbuckle is again operated, which will cause the mold-sections to be positively and evenly moved toward each other because of the swinging link connections 21 and the cross-bars 35, that now i 5 act the same as said links. The core is thereby completely disengaged from the side walls and may be readily lifted out, for it will have sa'asse position between the side walls and restsdirectly upon the pallet with the bottom uppermost, as illustrated in Fig. 9. said bottom will thus be below the upper edges of the outer walls, and the spaces between the side walls of the core and the outer side walls are closed by filler-bars 38, that fit snugly between said walls and are supported flush with the upper face of the core-bottom by standards 39, resting upon the pallet. The upper faces of the filler-bars 38 have longitudinally-disposed grooves 40, that are V-shaped in cross-section. When the parts are arranged as shown in Fig. 9, the material is poured upon the bottom until it is flush with the upper edges of the outer walls. Thus a top is formed corresponding in size to the body and having ribs in its under margins which will fit in the grooves i formed in the upper edge of the body. It

will thus be seen that a simple structure isprovided which will effectually hold its shape during the molding operation and which can be readily collapsed and dismembered in order to disengage it from the article with out injuring the same. Furthermore, the mold can be employed for forming both the body and cover of a vault or other box. It is also to be observed that the parts are simple and are of a nature that will withstand the pressure and rough usage incident to the manufacture of concrete and similar structures. There is nothing of a delicate or unsubstantial nature that is liable to derangement.

From the foregoing it is thought that the construction, operation, and many advantages of the herein-described invention will i be apparent to those skilled in the art without further description, and it will be understood that various changes in the size, shape, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificingany of the advantages of the invention.
