CALIFORNIA CONCRETE-FORM-BINDING TOOL Application led December 9, 1927. Serial No. 238,985.
Our invention pertains to wire and strap iron snubbing brackets for binding concrete structural forms inrigid position, and has for its objects, among others, to provide a tool which can be easily and quickly placed by one man; that does not mar the lumber; by which the binding wire or strap may be tightened to any necessary degree and that may be locked in taut position instantly; that is simple in operation, durable, economical of employees time, and cheap to manufacture.
These objects we attain by the provision, formation and assemblage of the members and parts illustrated inthe accompanying drawings, in which Figure l is a side elevation of the complete tool.
Figure 2 shows application of the tool in two positions on the form work of a concrete Y Y2c wall.
Figure 3 is a cross section of the operating bracket and lever handle in closed position (A), and open position (B), and the gripping members therein.
Referring more particularly t0 the drawlngs: I
1 indicates the operating bracket of the tool, and 2 indicates a companion bracket for the fixed end of the wire or strap.
3 indicates a hollow lever handle, pivoted within rearwardly projecting Iianges of bracket 1, on pivot 5.
4 indicates al rectangular transverse block riveted to handle 3 to provide an integral 35 part thereof.
6 indicates a rectangular transversely positioned block eccentrically revoluble on pivot 5 and adapted to co-act with block 4 in gripping action.
7 indicates a wire or strap adapted to hold outside and inside wales of a concrete form in rigid position toprevent spreading.
8 indicates transverse slots stamped in the rear face of bracket 2, adapted to allow a` metal strap to pass therethrough for snubbing purposes, the metal between said slots being stamped to form a groove exterior to Vthe body of the bracket adapted to receive wire 7 therethrough for snubbing purposes.
4 and 6 (not shown) -to afford safer gripping y for wire, and to avoid shearing the same.
Y The brackets herein described are intended to be placed atintervals of approximately 24 inches on the horizontal wales, and to avoid slde pullor twisting effects thereby it is best to stagger them, i. e. that the bindingwire or strap be placed above and below the wale alternately. The position ofthe lever handle 1n closed position, up or down, is shown in Figure 2.
The procedure in proper use of this tool isto apply the binding wire or strap (as the case maybe) and snub-one end in vbracket 2,
through groove or slots 8; place bracket 2 on a wale where tongue 9 will hold itin place while the other end of strap y"I is passedthrough the form to bracket 1 which has been positioned kon the corresponding wale. The loose end of strap 7 is passed between gripping members 4 and 6 while lever 3 is in open position. K one hand on the exposed end of strap 7 lever handle 3 is moved from open to closed position, this movement serving to automatically grip strap 7. As the movement progresses the slack or strap 7 is taken up to.
a maximum of the diameter of the circle described by the contact points of members 4 and 6. y
Any degree of tension on the strap less than the maximum isreadily' controlled by the While traction is made by- Cil Seo
amount of hand traction when the movement of handle 3 is begun.
Reversal of the above outlined process will serve to release the traction on strap 7 and the brackets may be removed, although it is more expeditious to cut the strap at convenient points and then clear the brackets.
It will be apparent that various changes and modilications may be resorted to without departing from the spirit and scope of our invention, and we do not wish to limit ourselves to the -fexactdisclosures herein. p
Having thus disclosed our invention and its mode of operation, we claim as new and Vseek Letters VPatent Aof the United States upon: f Y
