Figure 1 3: "Blue separators or partitions beingnlihe, it tollo ws that they are interchangeable i and the true otrthe-sideand end-pieces Elieend pieces QHaind-the' separators 7 are provided witl 1- openings 8 in coincident position i to receive cores 9, whereby the blocks when iiormeid are hollow orare provided-with en- 1 larged openings, this be' new of advantage in a building-unit otthe naturestated.

The core is of oylindrical tormand is preferably constructed of sheetinetal rolled into cylindrical form and havingedge portions overlapped, as indicated inostelearly in Figures l: and 5. One ed-geportion ot the sheet metal blank or strip coinprisingthe core is formed into a roll 10 in which is fitted a rod 11 and the opposite edge portion is provided with extensions 12 which are bent inwardly about the end of the opposite overlapping end porsa-me is" jot-, increased separators or formed in the end pieces end to provide for a play incident: to

The core is adapted to be contracted and expanded to facilitate the removal and to enable the same to be readily placed in position when assembling the mold. Clips 14 are attached to the inner side of the core a distance from therolled edge 10 and receive a rod 15 similar to the rod 11, both rods 11 and 15 extending through the core and beyond the ends thereof.
The core is adapted to be contracted and expanded by means of an appliance embodying similar bars 16 which are pivotally connected intermediate their ends, as indicated at 17.
the ends thereof. The projecting ends of the rods 11 and 15 are connected to the projecting ends of the bars a loose connection with the bars 16 at one contraction and expansion of the core. The bars 16 have a pivotal movement and in consequence of the central position of the pivot fastening 17, both ends of the bars have a like movement with the result that-the core 1S uniformly contracted and expanded throughout its length. An td1t1$t111g screw 18 disposed at one end of the pivoted bar- 16 is connected to one of the bars by means of a swivel joint 19 and has screw thread connection 20 at its opposite end with the other bar, and in consequence of this arrangement, rotation of the screw 18 efiects a pivotal movement of the bars 16 and a contraction or an expansion of the core according to the direction of rotation of the screw.
When the moldisassembled, the side and end pieces 1 and 2 are made secure by the fastening means 3 and 4, after which the partitions 7 are placed in position and receive the cores 9 which are passed through the coinciding openings 2 and separators 7. The mold thus assembled is placed upon a surface which forms a bottom therefor and the concrete or other material is filled into the mold and tamped the em and is struck or leveled by passing a straight edge over the top of the mold. After the material has set to render it safe to handle the blocks, the cores are contracted by operating the screws '18 and when sufficiently contracted are with- The bars 16 are. of a lengthto pass through the core and extend beyond 16, the rods havingv drawn from the mold by an endwise movethereby permitting removal of said ends and the side pieces, after which the separators or partitions 7 may be withdrawn. The construction is such as to admit of the mold being readily assembled, since the parts are not required to be placed in predetermined position, it being clear that the separators, aswell as the end and side pieces, are interchangeable.
What is claimed is:
1. A core for amold, the same consisting of sheet material formed into a cylinder, and means for contracting and expanding the core, the same consisting: of two bars pivoted intermediate their ends, and means applied to an end of the bars to separate or draw the same together.
2.- Acore for a moldadapted to be contracted and expanded, two bars pivoted intermediate their ends and disposed within the core, means connecting opposite ends of the bars to end portions of the core, means applied to an end of the bar to separate or draw the same together.
3. A core comprising sheet material bent into cylindrical form and having edge portions overlapped, a rod attachedto the edge and the inner edge portion, and a tie strip connecting the folded extensions.
5. A core comprising a blank terial formed into a. cylinder edge portions overlapped, the outer edge portion having extensions at opposite ends which are bent inwardly to engage about the inner edge portion, atie strip connect ing; the folded extensions.and'means within the c'ore'to effect-acontraction and an exp ansion thereof.
In testimonywhereof I in presence of sheet maand having affix my signature of two witnesses.
