MOLD.

Specification of Letters Patent.

Patented Feb. 18, 1913.

Application filed February 9, 1912. Serial No. 676,617.

To all whom it may concern:

Be it known that I, CHARLES W. Mo- DANmL, a citizen of the. United States, residing at Memphis, in the. county of Shelby and State of Tennessee, have invented certain new and useful Improvements in Molds, of which the following is a specification, reference being had to the accompanying drawings.

This invention comprehends certain new and useful improvements in moldingapparatus and relates particularly to a mold for use in forming concrete burial vaults, although it is to be understood that the invention is not limited to this use.

The invention has for its primary object a simple, durable and efficient construction of molding device, theparts of which may be easily cast and otherwise fprmed and readily assembled for use and disassembled for the purpose of removing the vault, or for other purposes, the invention also having for one of its primary objects a simple construction of molding apparatus, both the core and flask of which are so arranged that they may be extended within certain limits or retracted, as required,-to form vaults of difierent sizes, or vaults with walls of varying thicknesses. I

' The invention has for a further object an improved construction of mold, the core of which is provided with simple and efiicient latch devices designed to temporarily hold together the sections of which the mold is formed, whereby the core in its entirety will be a substantial and rigid structure, while at the same time it may be easily knocked down and removed, when desired.

And the invention also aims to generallyimprove this class of devices and to render them more useful and commercially desirable. Y

With these and other objects in view, as will more fully appear as the description proceeds, the invention consists in certain constructions, arrangements and combinations of the parts that I shall hereinafter fully describe and claim.

For a full, understanding of the invention, reference is to be hadto-the following description and accompanying drawings in which, I

Figure 1 is a top plan view of a mold constructed in accordance with my invention. Fig. 2 is a sectional view thereof on the broken line 2-2, of Fig. 1. Fig. 3

(Sheet 2) is a transverse sectional-view on the line 3- -3, of Fig. 1. Fig. 4 is a similar view of the core on the line 4-4, of

in the accompanying drawings by like ref-- erence characters.

The flask A- of my improved mold embodies sides 1 and ends 2, as best illustrated in Fig. 1. Thesides 1 are each formed at one end w1th upper and lowerlongitudinall extending slots 3 and are interiorly thic ened and preferably rounded at the opposlte end, as at 4. The end 4 of one side is arranged diagonally in relationto the other side. The ends 2 of the flask A are correspondingly slotted at one end, as indicated at 5, and interiorly thickened at the opposite end, as indicated at 6, the slotted and interiorly thickened ends of the parts 2 being also arranged in diagonal relation to each other, as best illustrated in Fig. 1. Set screws 7 work inwardly in the thickened ends 4 and 6 at the corners of the flask and are received in the adjoining slots 3 and 5 of the parts heretofore described, the parts being so proportioned and arranged that they may be extended or moved inwardly over each other to a limited degree and yet to the'maximum required in a device of this character, the parts being securely held in adjusted position 'by tightening up the set screws 7. Preferably the outer faces of the sides are formed with inset anels 8 designed to produce correspon ing intaglio panels .in the body portion of, the. vault formed therebyv and the ends 2 of the flask A are correspondingly formed with panels 9.

The coreof the mold, is indicated .B as a whole, and includes angular corner sections 10, each of which forms a part of one side and of one end of the core. The'core, as will be evident by the accompanying drawings, is frame-like in character and 1s constructed of four main parts or castings that are held in at their adjoining ends b flanged spacingmembers 11, one of 'whic is shown in detail in Fig. 5.' Preferabl these spacing members are downwardi; tapered, as indicated in Figs.- 4 and 5, and

are adapted to fit within vertical flanges 12 formed on the sections 10 at the opposite ends thereof. In order to secure the spacing membersin place, hand-operated latches 13 are provided. Each latch 13 is formed at one side with an aperture 14 by which it is pivotally connected to the outer face of one of the flanges 12, each latch being fur ther formed with a handle 15 and with spaced lugs 16 that, in the operative position of the latch, are designed to straddle the outer faces of the flange 12 to which the latch is connected and the adjoining inner wall of one side of the corresponding spacing member 11. This is clearly indicated in Fig.4 and also in Fig. 3. In order to assist in guiding the spacing members into their positions and to maintain them properly in place when locked by the latches 13, each spacing member is provided at its upper end with outstanding lugs or nibs 17 designed to fit within the downwardly tapered recesses 18 that are formed at the juncture of the upper ends of the flanges 12 and the upper horizontal flanges 19 of the sections 10 (see Fig. 4).

The entire core B-,is in the present embodiment of 'the invention supported with its bottom flanges in spaced relation to the base-board which is designed to support the flask A, by transversely extending bars 20,

the ends of which extend over and rest detachably upon the upper edges of the sides 1 of the flask, as at 21, the intermediate portions of.the bars being secured 'to the upper flanges 19 of the sect ons 10 of the core B by bolts and nuts, as indicated at 22. By this means, the core may be easily inserted in place with its parts in assembled relation to each other.

From the foregoing description, in connection with the accompanying drawings,

, the operation of my improved molding apparatus will be apparent. In the practical use .of the device, the parts of the flask A ,are set up and adjusted, as required, ac

' cording to the particular size of burial vault to be molded, and the sections 10 of the core B are secured together by means of the intervening latches 13 and the spacing members 11, it being understood that spacing members of varying widths are to be employed according to the particular size it is desired the core B shall have. After the sections 10 of the core B have been securely locked together with their intermediate spacing members 11, by pressing downwardly upon the latches 13, the entire core is set down into the flask A, it being-held in suspended position therein by the ends 21 of the bars 20 extending over the upper, ed es of the sides 1. It is to be understood t at any of the methods ordinarily employed with molding apparatus of this character, may be employed with my improved molding apparatus. For instance, the concrete may be poured into the flask A up to a predetermined level, the core B may then be inserted in position, and the concrete then poured in around the spaced walls of the flask and core to complete the body portion of the vault. Preferably, the flask B -is formed at its upper edge and on its exterior wall with a head 23 substantially rectangular in cross section, said bead being designed to form, in the completed article, an interior upwardly facing channel designed to receive the lid or cover of the vault. If desired, the cross bars 20 that are designed to support the core within the flask, are set in recesses 24 formed in the upper edges of the sections 10.

It will thus be seen that I have provided a very simple and efiicient construction of molding apparatus, particularly designed for use in forming the body portions of concrete burial vaults, and that the parts may be easily assembled and very readily knocked down and disassembled, or adjusted, as the particular requirements of the case may demand.

While the accompanying drawings disclose what I believe to be the preferred embodiment of my invention, it is to be understood that the invention is not limited thereto, but that various changes may be made .in' the construction, arrangement and proportions of the parts without departin from the scope of the invention, as define in the appended claims.

7 What I claim is 1. A mold of the character described, including a flask, a core co-acting with said flask, the core being constructed of angular sections, each of which is designed to constitute a portion of one side and of one end of the core and the sections formed at their ends wit-h substantially vertical flanges, flange spacing members adapted to fit be-- tween the ends of the sections to complete the continuity of the core, pivoted latches carried by the flanges of the sections and adapted to overlap the flanges of the spacing members, whereby to detachably connect the spacing members to the sections, the latches each bein formed at one side with an apertured ear y which it is pivoted to a flange of a section and being also provided with laterally spaced lugs extending at right-angles to the ear and adapted to clamp together the said flangeand one of the flanges of the adjoining spacing members.

2. A mold of the character described, including a flask, a core co-acting with said flask, the core being constructed in sections, each of which is designed to constitute a portion of one side and of one end of the core and the sections formed at their ends with inturned flanges, said flanges diverging upward and outwardly, tapering flanged spacing members adapted to fit between the ends of the sections, pivoted latches carried by. the flanges of the sections and adapted to overlap the flanges of the spacing members, whereby to detachably connect the spacing members to the sections, the latches being each formed at one side with an apertured. ear by which it is pivoted to a flange of a section and" being also provided with laterally spaced lugs extending at right angles to the ear' and adapted to clamp together the said flange and one of the flanges of the adjoining spacing members, each spacing member being formed at its top with outstanding 15 lugs and the sections being formed with recesses for the reception of said lugs.

In testimony whereof I hereunto aflix my signature in the presence of two witnesses.

CHARLES. W. MoDAN-IEL.
