To all whom it may concern Be it known that we, HENRY S. RAY and EARL RAY, citizens of the United States, and residents of Louisiana, Pike county, Missouri, have invented certain new and useful Improvements in Tools for Tying-Reinforcing-Rods, of which the following is a specificationcontaining a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

Our invention relates to improvements in tools for tying reinforcing rods, and the object of our invention is to construct an inexpensive and durable tool for picking up reinforcing rods used in connection with concrete work and for bending metallic ties over crossed reinforcing rods.

Vfith the above purposes in view our invention consists in certain novel features of construction and arrangement of parts as will be hereinafter more fully described, pointed out in the claim and illustrated by the accompanying drawings in which.

Figure 1 shows in elevation a tool embodying our invention; Fig. 2 is an elevation of the tool taken at right angles to Fig. 1, a portion of the lever thereof being broken away; Fig. 3 is a sectional plan taken on the 33 of Fig. 1, the spring being removed; and Fig. 4 is an elevation similar to Fig. 1 showing indotted lines the posi tion of the tool in elevating the reinforcing rod and also its position after having'completed the tie.

Referring by numerals to the accompanying drawings: 5 designates the lower jaw of our improved tool. Formed integral with the lower jaw is aweb 6 having at its lower end a plate or base 7.

8 designates the upper jaw of the tool having integral opposite perforated ears 9 arranged to straddle the lower jaw 5 and' pivotally connected with the lower jaw by means of a bolt 10.

' 11 designates a lip carried by the upper jaw which is arranged to engage the tying element as will be hereinafter more fully explained. The edge of this lip is. preferably serrated in order that it will hold more se- ,curely to the tying element during the act of forming and tying.

For normally holding the aws separated Specification of Letters Patent.

said reinforcing rods.

we provide a contractile coil spring 12 which is connected at its one end to a pin '13 carried by the lower jaw and at its other end to a perforated ear 14 which ear is secured to or forms a part of an operating lever 15 preferably formed integral with the upper jaw 8. This tool is especially designed for use in connection with metallic ties, such as the one which is shown in Fig. 4, having a blase or support 16 and two arms such as K.

Inpractice the plate or base 7 is inserted beneath the lowermost rod, the tapering formation of the base facilitating said insertion, and the entire tooltilted rearwardly, as shown by dotted lines in Fig. 4, which elevates the reinforcing rods. Tn elevating the rods, as just described, the tool is placed at a point removed several inches from the crossed-rods, so that-it will not be in the way of the placing of the tying element. In this elevated condition of the rods the tying device may be readily placed in position straddling the lowermost rod and against the uppermost rod on a side toward the tool. The tool is then moved to the pothem over the upper reinforcing rod. The

tying by such a tool is more secure than ordinary tying for the reason that the tool'when operateddraws the two rods together and the tying is accomplished about two rods held firmly together.

as shown by dotted lines in Fig. 4, the jaw cause it to be tilted upwardly at its forward end, thereby elevating the reinforcing rods so that the tie may be readily slipped onto We claim V In a tool for tying reinforcing rods for concrete work, a base comprising faces ar ranged at an angle relative to each other, an element hingedly connected with the base,

'a lip carried by said element and overhanging one of the faces of said base, the other face of said base constituting means,

It is to be observed that when the lever 15 is tilted rearwardly,
