MOLD.

Application filed March 4, 1924. Serial No. 686,862.

To all whom it may concern:

Be it known that I, FRANK P. BUNKER, a citizen of the United States, and resident of North Manchester, in the county of Wabash and State of Indiana, have invented certain new and useful Improvements in Molds, of which the following is a specification.

My invention relates to improvements in collapsible brick molds, and it consists in the combinations, constructionsand arrangements herein described and-claimed.

More specifically, the'present invention is an improvement over that disclosed in Letters Patent of the United States 1,268,676 grantedto me June 4th, 1918, or an improved brick mold, and contemplates the provision of a brick mold comprising separable side and end members and partitions, the side and end members being adapted to be removed from bricks which are formed in the mold to rest upon a pallet without there being any necessity of removing the partition from positions between the bricks, whereby the bricks with the partitions therebetween may remain on the pallet until the bricks are cured while the side and .end members may be used with other partitions and pallets to form additional bricks.

A further object of the present invention is to provide a collapsible brick mold having the side members and the end members thereof provided with novel cooperative locking elements for releasably holding the side and end members in assembled position the pallet having means engaging with themold when the latter is assembled tending to hold the mold in centered position on the pallet without preventing separation of the end members of the mold from the side members thereof when desired.

Other objects and advantages will be apparent from the following description, considered in conjunction with the accompanying drawings, in which- Figure 1 is a perspective view showing a mold embodying the present invention in position for use on a pallet,

Figure 2 is an elevation of one of the end members,'showing the normally inner wall of the. latter,

opposite endswith an upper substantially hook-shaped or right angular locking extension 3. and a lower similar locking extension 4. The bill portion of each of the substantially hook-

shaped locking extensions

3 and 4 extends downwardly vfrom the body of the locking extension. The inner wall of the bill portion of each of the locking'extensions 3 is inclined upwardly and inwardly from its lower end as indicated at 3*, Likewise, the inner walls of the bill portions of each of the locking extensions 4 are inclined upwardly and inwardly from its lower end as indicated at 4: The upper locking extensions 3 extend from. the upper corner portions of eachendmember 1 in the plane ofthe end member .while the lower locking extensions 4 extend from the lower corner portions ofthe end member.

The side members 2 are adapted to cooperate with the end members 1 Each of the side members 2 issubstantially rectangular and is provided at each of its opposite ends with an upper substantially hook-shaped or right angular locking extension 5 and with a lower similar locking extension 6. Each of the locking extensions 5 "or 6 has the bill portion, thereof extending upward from its juncture with the body of the locking extension. The inner wall of each locking ex tension 5 is inclined downwardly and in wardly from its upper end as indicated at end members 1 are adapted to engage with the corresponding locking extensions on the side members 2 so that the side members and the end members will be releasably held in position to provide a frame that is rectangular in horizontal sectional contour and hasvertical end and side Walls. Since the inner walls of the bill portions of co-engag ing locking extensions are inclined as described, the meeting portions of adjacent side and end members of the frame willbe dra n t ght y again t eachother when the cooperative locking extensions of such side d end m m ers are engaged w h each t r- The de nd end membe the e will be tightly connected together at the corners of the frame and at both the upper and lower ends of the frame.

The inner faces of the end members 1 preferably are smooth while the side members 2 are provided with spaced apart vertical grooves 7 in their inner faces extending the full height thereof, corresponding grooves 7 of the two side members being in alignment transversely of the frame and being adapted to engage with the end portions of a substantially rectangular partition 8 which is slidable vertically in the frame.

Each of the end members 1' is provided with a horizontal lug or strip 9 on the outer face of theend member, the lug or strip 9.

being adapted to serve as a handle or hand holdl a r A pallet for use with the frame is indi cated at 10 and has a flat upper face, preferably, although not necessarily, comprising an upper face plate of suitable metal, such as sheet iron, secured upon a wooden base.

An elongated stop or bumper-.11 is secured on the pallet lOin proximity to one longitudinal edge of the latter and in parallel relation to. such longitudinal edge. .A similar stop or bumper 12 is secured upon the pallet 10 in proximity to one transverse edge of the pallet and in spaced parallel relation to said transverse edge. The arrangement is such that the frame will be disposed substantially in centered relation on the pallet when the frame is placed on the pallet with one of the end members thereof against the stop 12 and one of the side members thereof against the stop 11.

From the foregoing description of the various parts of the'device, the operation thereof may be readily understood. "The interior of the mold comprising the frame resting upon the pallet in the manner described is divided by the partitions 8 into. a plurality of compartments, each open at its upper end and into which brick forming material may be placed to form bricks of a desired size. While in practice, the spacing between the side walls of these compartments will be such that the bricks will be formed fiatwise'therein, it is obvious that pros-'ision may be made for forming the bricks edgewise simply by spacing the grooves 7 of each side member 2 apart so that. the height of each of the compartments of the mold will be greater than the width thereof. Also, it will be manifest that the size of the bricks which are to be formed may be varied by varying the spacing between the grooves 7 of each side member of the frame and if sordesired, the grooves 7 may be omitted and the inner'faces of the side members 2 formed smooth so that a mold adapted for use in forming one large block of any suitable material will be provided.

After the compartments of the mold have been filled with brick forming material, the handles or hand holds 9 of the end members may be grasped and the end members may be lifted bodily until the cooperative locking extensions of the end and side members are in such position in respect to each other that the end and side members may be separated simply by moving such members laterally outward. The molded bricks spaced apart by the partitions 8 may remain on the pallet 10 "until hardened and cured while the side and end members may be used without delay with other partitions 8 and other pallets 10 in forming additional bricks.

Obviously, my invention is susceptible of embodiment in forms other than that illustrated in the accompanying drawings and I .sion andv a lower hook-like extension at each of the opposite ends thereof, the bill portion of eachhook-like extension depending from its juncture with the body of the extension, anda pair of substantially rectangular end members cooperating with said side mem bers, each end. member having, an upper hook like extension and a lower hook-like extension at each of the opposite ends thereof for engaging with the cb rresponding hook-like extensions at one end of one of theside members, the bill portion of each hook-like extension to an. end member depending from its juncture with the body of' the hook-dike extension.

'2. In a mold of the character, described, a pair of substantially rectangular side members, each having an upper hookike extension and a lower hook-like extension at each therefore consider as my own all modificaof the opposite ends thereof, the bill portion of each hook-like extension depending from its juncture with the body of the extension, and a pair of substantially rcctangular end members cooperating with said side members, each end member having an upper hook-like extension and a lower hooklike extension at each of the opposite ends thereof for engaging with the corresponding hook-like extensions at one end of one of the side members, the bill portion of each hook-like extension to an end member depending from its juncture with the body of the hook-like extension, and the inner Walls of the bill portions of co-engaging hook-like extensions being oppositely in- FRANK P. BUNKER.
