Combined clamp and spreader.

Application filed March 15,1907. Serial No, 362,526.

To all whom it may concern:

Be it known that we, John R. Zeisek and Adlow Zeiseb, citizens of the United States, residing at Berwick, in the county of Colum5 bia and State of Pennsylvania,.have invented certain new and useful Improvements. in Combined Clamps and Spreaders, of which the following is a specification. .In building concrete walls, the .material is 10 confined between side pieces which are required to be held -apart the proper distance and prevented from outward displacement, said side pieces -being removed after the section confined thereby has set sufficiently to 15 retain.,i^s shape.

The present invention relates to means for holding the side pieces, crib members or former sections, in place so as to prevent both ’ inward and outward displacement thereof, 20 said means , being readily adjustable to any thickness of wall. ' .

For a full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction ano 25 the means for effecting the result,, reference is to be had to the following description and accompanying drawings. . _Λ

While the invention may be adapted to different forms and conditions by changes 30 in the structure and minor details without departing from the spirit or essential features thereof, still the preferred embodiment is shown in the accompanying drawings, m which: ,

Figure 1 is a top plan view of a section ot wall, showing a crib or former in position ιοί the next section, the outer ends of the members of the crib or former being held in place . by a clamp and spreader embodying the inven40 tion. Fig. 2 is a perspective view' or tne clamp and spreader. Fig- 3 is a front view of the device, an end portion, of one ot the members being broken away and the dotted lines showing the relative position ol the 45 members, when released to admit or then, adjustment. Fig. 4 is a detail perspective view of the clamp ,and spreader memberprovided with hooks and a stop.

Corresponding and like parts are reieixed 50 to in the^xf olio wing description and indicated in all the views of the drawings by the same reference characters. .

The clamp and spreader comprise cpniplemental members 1. and.2. The members 1 55 and 2 are.relatively adjustable to admit of lengthening or shortening the device according to the thickness of th0 wall to be constructed. Each member is provided. at its outer end with spaced lugs 3 and 4 which embrace opposite sides of the, members 5 of 60 the crib or former adapted to receive the concrete or other material employed in the formation of the wall. ’ Each member consists of a bar, the outer end of which is split longitudinally and the portions bordering 65 upon the cut bent laterally to provide the lugs 3 and 4. The distance .between p pair of lugs corresponds to the thickness of the crib or former member 5.f - ,-

One of the members, as 2, is provided at 70 opposite edges with hooks. 6 and 7 which are located at different points in. the length of the member and are formed by partly severing edge portions of the bar and bending the parts between the cuts to form the hooks. The 75 hooks 6 and 7 are adapted to embrace opposite edge 'portions of the member 1 so as to hold the two members in fixed position when adjusted, and properly fitted together. A stop 8 is provided at the end. of the member 80 2 opposite that provided with the spaced lavs 3 and 4 and acts jointly with the hooks 6 and 7 to retain the members 1 and 2 in proper position. A longitudinal cut extends inward, from the extremity of the 85 member 2 near one edge thereof and. the part thus separated is bent outward from the side'having the hooks 6 and 7 to lorm the stop 8 which is adapted to engage the smooth edge of the member 1 and hold the 90 same in place. . . .

The member 1 is reduced in width between its end portions, and the edge bordering upon the space formed by cutting away aifedire portion of the member is notched to 95 form teeth. The hook 7 of the member 2 is adapted tin enter a selected space between adjacent teeth so as. to hold the members . 1 and 2 from longitudinal displacement. The edge portion of the member 1 opposite 100 the toothod edge is adapted to be engaged by the stop 8 and'by the hook .6, and since the hook 7 is located, intermediate.of the stop 8 and hook 6, the members 1 and. 2 when adjusted are prevented from turning,, nut 105 upon Dressing the members 1 and 2. apart to. cause the stop 8 to clear the member 1, the. latter may be turned about as indicated in Fi®·. 3, thereby releasing.the member from the hooks 6 and 7 and admitting of the mem- 110

874,151 bers being adjusted to any position within their range of movement, and when adjusted to the required position, the members are brought into alinement and are held 5 m fixed-adjusted position by the hooks 6 and 7 embracing opposite edge portions of the member 1, and the stop 8, in the manner hereinbefore stated.

When starting a wall, the side pieces 5, 10 or the crib sections, may be held in proper position by having clamps and spreaders applied to· opposite ends or edges as will be readily understood. After a section of wall has been formed as indicated at 10 in Fig 1 of 15 the drawings, the side pieces or crib sections 5 are removed and adjusted for the next section ot wall to be constructed. The ends ot the crib sections 5 adjacent to the section ol wa 1 10 previously constructed, are ar20 ranged to embrace said section and are clamped thereto by means of a tie rod or bolt 11. lhe opposite ends of the crib, sections o are secured and properly spaced by having >_t ??? /',¹,¹¹⁰¹'⁰' combined clamps and spreaders 25 fitted thereto m a manner substantially as indicated in Fig. 1. It will thus be understood.that the crib sections are not only held irom inward and outward displacement, but are spaced apart the required distance It 30 will also be understood that the combined clamp and spreader may quickly be removed and instantly placed m position and that the same may be adjusted to different thickncss of walls. The parts of the clamp and 35 spreader may be separated to be placed in compact form or may be adjusted, or may be instantly adjusted to meet any requirement both as regards assembling the parts or adapting the same to any thickness of iv tV <111.
