CONCBETEFORM.

Specification of Letters Patent.

Patented Feb. 20, 1917.

Application filed September 24, 1915. Serial No. 52,444,

To all whom it may concern:

Be it known that I, JOHN L. JANISGH, a citizen of the United States, and a. resident of the city of Chicago, county of Cook, and State oflllinois, have invented certain new in Concrete- My' invention relates to improvements in concrete molds especially adapted for use 111 forming burial vaults, caskets and the .like, the object of the invention being to provide an improved construction of this character which is simple and efficient in use.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings forl'ning a part of this specification, and in which,

Figure l'is av side .vieW of a mold arranged to form the body of a burial vault, embodying my invention,

Fig. 2, a longitudinal section of the same taken on line 2-2 of Fig. 1,

Fig. 3, a top" lan view of the same,

Fig. 45a transverse section taken on line 4-4 of Fig. 3,

Fig 5, an enlarged perspective view of a corner joint'employed in the core of the mold, and

Fig. 6, a similar view showing parts detached. T

'lhe'prciierred form of construction, of

mold for forming the body of the vault com prisesa base plate members 16. and end members 17 removably arranged OIl SEl'ld base member to const tute the outer wall of the form. Cleats or stops lS'and 19 are arranged onthe base member 15 in positions to engage the lower edges of the side and end members 16 and 17 to limit outward mo ent thereof. The end members 17a b it their extremeends tocon'stitute co l 0; ti and are connected with the side members 16 by means of stepped joints 20, as indicated inFigf3. Slidable strips 21 are slidably secured to the outer sides of side mom here 16 by means Of'SlOtand bolt connections 22"whereby said slides may be fitted overthe stepped joints 20 to further posi tion the end members 17"i1i place: A substantially U'shaped clamping member 23 is arranged around the sides and aeross'one sition the lower ends of sai core members.

15 and removable side corresponding P0111011 of the v ult V, dicatcd in ie outer mold form 5 outer form member just describeil, said core member comprising side member-sol walls 27 and end members 28, said side and end members being connected together at the corners by inwan ll movable corner memhers 29 having stepped joints 30' with the corresponding side and, end members, best illustrated in Figs and 5. Slides 31 arc'sl'idably secured to the inner walls of the side and end members 27 and 28 by means of bolt and slot connections 32 and by means of which the'corncr members may be secured in place or released for inward movement in collapsing the core:

The sidemembers 2'7 and the end members 28 are pron: led with centrally posi. tioned downwardly projecting securing pins 33 and 3-9: respectively, arranged to fit within corresponding openings in base 15' to po- A core top memberfia is. arranged to fit within tlie'side and enl members 27,..and' resting upon supports 36 in the form of angle members secured to the. inner walls i of said "do and. end members, the horizontal legs o'fsaid angle members being perforated to receive downwardly "projecting pins 37 on said 'top member 35. The top member is provided on its under side with centrally positioned. handle ring to assist in nmnipulating the same." 1A V-' shaped rib 39 is formed on the'base member 15 between the outer form; and the in: nor core to form a Vshapedgroove inthe formed in the'mold. 1

In use, the partsz are assembled as best m Figs. 1, 2, 3 and t, and the, space between the core member and the outer form member and abofvextbe core member filled 10 5 "with a suit-able concrete m1xture,in.the usual manner. 'After this mixture has setor be come hardened the nuts 26ers loosened and H There-"1 loosened and the slide ,110

the clamping 'member '23 removed. upon nuts 22 are 1nen1bc-rs 21- moved back tofacilitate ,r'emoval of the side and end members 16 and 17. Then the form is turned upside down, 7

thefbasefmember 15 removed.

er and the corner members 29 are readily I removed therefrom'by loosening the bolts of the connection 32 which permits of the ready'removal of the side and end members. Then the core top member 35 is removed by means of handle member 38, thus finishing the operlation. Y

The form of construction set forth will be found to be a simple and efficient one for the urpose.

hile I have illustrated and described the preferred form of construction for carrying my invention into direct, this is capable of variation and modification without departin" from. the spirit of the invention. 1, there ore do not wish to be limited'to the precise details of construction set forth,

but desire, to avail myself of such variations,

and modifications as come within the scope of the appended claims Having described my invention what I claim as newand desire to secure by Letters Patent is:
