COLLAPSIBLE FORM FOR CONCRETE CRYPTS.

Application sled August 3, 1926. serial No.` 126,831.

This invention relates to a collapsible form for casting concrete burial crypts and more particularly to such a forni which is economical in construction and which can be easily set topour the concrete and easily collapsed and removed by withdrawing the lower members of the two collapsible side walls of' the form.

VOne of the objects of the invention is to provide a collapsible form for casting concrete burial crypts in which the form, after the concrete has been poured in to form the crypt, is surrounded yby the concrete and in which, 'after the concrete has set, the side pieces of the form may be collapsed, thus permitting the collapsing and withdrawing of the torni without injuring the concrete of the crypt, or the form.

rAnother objectof the invention is to provide such a collapsible form that can be readily and conveniently used for casting a series ofconcrete crypts lin rows and tiers, the form having an open bottom vand its sides resting on the loor or" concrete for1ning the roof of the tier previously cast.

' Another object of the invention is to provide such a forni, the two side walls each consisting of two side pieces, the upper side piece provided with transverse battens and meeting the lower side piece at an inclined angle so that the lower side piece may be withdrawn from beneaththe upper piece, dropping the feet of the battens otl the upper piece, to the supporting floor and colla psing the form.'

' VW ith the above and other objects in view, the invention consists in the parts, improvements and combinations more 'fully pointed out hereinafter.'

Referring now to the'drawings:v

Figure l, is a vertical,,longitudinal section showing the collapsible form resting on the top of a` previously cast crypt, with the concrete poured around it.

Figure 2, is a longitudinal, transverse section on line 2 2 of Figure l. y

Figure 3,' is 'av detail' showing the assembled open spacing frame placed at the bottom of the form for holding the sides apart while the concret-e4 is being poured.

4Figure 4V', is al detail view showingone of the two part sides. n y

Figure 5,is a detailed cross-sectional View, showing the'means for'hooking together a Figure 10, is a transverse, crossssectional view-showing a row ot' crypts being cast with a form in place.

Figure 1l is a perspective view showing a form in use in casting one ot' a row ot' crypts.

Turning now .to the drawings, the collapsible form includes a pair of sides, each side including two longitudinal side pieces l, 2. The upper side pieces are provided with a series ot' transverse battens 3, and the lower side pieces with a series of transverse battens 43. Both sets of battens 4cooperate and act as stops to limit the relative longitudinal movement of the upper and lower side pieces when the lower side pieces are pushed home and' when they are pulled out. The meeting edges ot' the upper and lower side pieces arc'y longitudinally inclined so that the upper piece meets the lower piece atan acute angle. As will more fully appear below, this will permit the upper piece to drop, when the lower side piece is pulled out by handle 7, so that the feet of the upper battens 3, will drop downward and rest upon the rooiC of' the crypt below. The transverse collapsing of the side pieces thus lowers the top of the torin'and enables the form to be collapsed.'

The top of the'forin preferably consists of two removable top sections 8 and 9, which rest upon the tops of the upper side pieces and upon the detachable back l04 of the form. The lback rariel the sides are preferably chamte'red at their meeting edges 10, so as to forni a close joint between the back and sidesiand facilitate the withdrawal ot the side pieces when the form is to be collapsed. Each top section is provided with a plurality of cross pieces 11, which serve as struts between the side pieces, resisting the collapsing ofthe form when the concrete is poured and stamped, these cross pieces resting on top of the battens 3. The rear cross pieces serve as stops for the top sections when the top sections arel slipped in place upon the back and sides, the cross pieces abutting against strips 10b secured" .to the bucle-1z0". 'Phe top" sect-ions en'tendbeyondf the 'front of the crypt at 12, these portions serving` as handles whenthe top sections are removed and receiving" Stringer 13"a`nd slat 1li, the slut limiting the flow of concrete and the stringer spacing the forms a predetermined distance apwart-` bybeing nailed to the liront portions of thetop sectionsm The topseetions are supported at their meetingA edgesby means Vo'l a; longitudinalbcam l5', which, in turn, is supported at the ends and an iuter^ine .li.at point.A The back end ot the be in rests in a pccket'l't'ormed on the back 1Q by a strip 16V and thev intermediate portion and iront vendl of the beam are supportedby ver

leal posts

17, 18, with i ailed to their tops between which cleats 1811,11 v p cleats the beam rests. The vertical posts rest, upon wedges 19,. 2O which, may bey knocked out when removing the beam and collapsing the form.`

. An openspacingtrame provided which includes' a pair

otlongitudinal strips

21, 22, grooved at 23. rlihe strips are placed on lateral struts 24,-y and the struts are each provided with a pair of top blocks 25, so as to holdl the

strips

21, 22 apart and firmly in place.` struts to keep the frame. oil the concrete floor.

This open frame provides a means for spacing; the lower portions of the form `and helps to prevent the lower sideV pieces from being force-d together when the concrete` is poured and tamped betweenadiace'nt fori'ns. The back and vthe topcross pieces 1'1, also help to maintain the 'form in its assembledI position and toA il'irevent the collapsing of the form when 'the concretev is poured. l y

After the 'form has been assembled, the workman, who can enter the form, may hook the parts together by means of hooks 27, which connect `the adjacent top sections, hooks 28, which connect the back and sides, hooks 29, which connect the back and top sections and hooks 30, which connectthe sides and the top sections at the front of the form. l

Boarding' 31, supported by braces232, is provided which limits the 'flow of concretev and y determines the thickness of the back wall oi the crypt. y

lVhen casting); an enlarged post at the end of the sidewall between adjacent crypts, as shown in Figure 6, lthe end of each si'dyevoil theform lis'provided with a laterallbl'ock 33, having; an inclined tace S4, against which a si de ojl* the post is cast. An auxiliary' form 3'5, is provided on the side of which is mounted a strip 36 with a wedge-shaped projection, 'thus producing a groove in the Feet 2G: may be provided for the,

post. The door 3f?, for the completed crypt may be moi'iintedfin therend of tlie'fvpost `and cement poured in between the door and the post, so as to lill the groove, after thecrypt is occupied-` AL ve-rtiealstrip 585i lfieldiin place by Stringer 39, is provided to form the ironttace of the post.

Having be clear. The 4iorm having` been'a'ssembled and the hooks used toV connect the parts, the. longitudinal beam and itssuplpo-rts having. been inserted to support the meeting' edges-f of the top sections, the openy spacing frame with its4 lateral struts having been placed in position andV theI boardinghaving,y been placed' about lthe outside of the` formvandf spaced therefrom, concrete isfpoured-` about thetorm andv tampedi'down between the agdjacent forms, tt'er. the concretehas'v set, the Stringer-s and outside pieces are removed and the form is collapsed by firstu'nhooking` the various hooks, then taking, down the. posts by knocking.; out the Wedges underneathand removing the longtudiiialfbeam l thus- ,descrilied the` constnuction, the operation otvtakingld'own thetorm will?!` supported thereby and then loosening the.V

spacing trame. as byftilting Aeither of-its sides upwardly and then removing it'.4 Eachlower side piece is then pulled vforward',,when casting thecrypt'` without', a front plost as shown in Figure 9, which permitstlie upper side4 pieces to drop so that theA feetv oftheir battens rest upon the concrete'oor. This action will release the top sectionsso ,that the topz sections and side piecesfcanbeitaken out. i'ter their removal. the back can, be taken out'. When vcasting the post li'ormfot'/ crypt, shoi'vn in Figure 6, the handle end 0i the lower side piece is irst sprung .laterally inwardly, so as to clear the post, andfthenpulled forward so as to allow theupperl side piece to drop down.

Having thus described the construction and operation, it will be understood. that changes may be madein carrying the invention into yeil'ect, without ,departing froml the principle ot the invention.,
