WIRE-BENDING DEVICE.

Specification of Letters Patent.

Patented Feb. 25, 1908 Application filed December 9. 1907- Serial No. 405.701.

ing and making loops on wire and it consists of two members hinged together and provided with wings, by means of which the wire can be conveniently and evenly looped or bent; and in other details of construction as set forth in the specification and more definitely pointed out in the claims.

In the accompanying drawings, forming a part of this specification, Figure 1 is a plan view of the device, showing a wire held in place after a full bend has been made therein. Fig. 2 is an enlarged perspective of the cen tral part of the device when opened to receive the straight wire. Fig. 3 is an enlarged transverse section on line 33 of Fig. 1. Fig. 4 shows a wire in which a right angle bend has been made. Fig. 5 shows a wire having its shorter end bent parallel to its longer end. Fig. 6 shows the same with its shorter end bent at right angles to its longer end preparatory to twisting and completing the loop. Fig. 7 shows the loop completed by twisting the bent end around the longer end of the Wire.

Referring to the drawings, A represents one of two members and B the other, which are hinged together at one end by a bolt or rivet C, one end of which projects out beyond the upper face of the member A, so as to come in contact with the wire D. It is preferable to make the hinged end of the member A bifurcated and to fit the hinged end of the member B between said bifurcated ends, but the faces a and I) should be in the same horizontal alinement to properly support the wire. The members are fitted with wings E and F which are in the same horizontal alinement as the projecting end of the rivet O, which forms a looping pin, and are preferably curved or inclined toward it.

They are so located that when the bender is open, as shown in Fig. 2, a straight Wire can be placed between the looping pin and the wings E and F. When in this position the wire will be firmly held and will be readily bent around the looping pin by drawing the free ends of the members together, as shown in Fig. 1. The length of the bend can be regulated by slipping the wire through the space between the looping pin and the wings to' the desired extent before closing. Also, different degrees of bends can be made by closing fully, as shown in Fig. 1, or by closing partially.

Fig. 4 shows a piece of wirebent so its ends are at right angles to each other, which may be done by half way closing the device. Fig. 5 shows a piece of wire bent so its ends are ing the device, as shown in Fig. 1. Fig. 6

central portion being bent so the ends are parallel with each other, and one of the ends being bent so as to cross the other and to stand at right anglesthereto. To make the bends shown in this figure, the wire is placed in the device so that the part I will be directly opposite the looping pin and the right angle bend is made by half closing, as in Fig. 4. The device is then opened and the wire is slipped along until the part J is opposite the looping pin and a parallel bend is made by fully closing, as in Fig. 5. Fig. 7 shows a complete loop which is made by taking the wire shown in Fig. 6, and twisting the end K around the other end, which may be done in any suitable manner, a device to do this twisting being shown in another application.

It is preferable to have the central part of the members A and B made of castings or wrought iron, and to have separate handles A and B of pipe or other material, secured thereto, but if preferred, they may be made integral. It is evident that instead of the wings E and F, pins or other means may be fitted on the members A and B and be used to catch and bend the wire around the looping pin. Also, that instead of the projecting end of the rivet O, a post or lug may be formed on the upper face of the member A around which the wire may be bent, or that other means may be used for this urpose, without departing from the spirit of my invention. The essential thing is the construction of the hinged members A and B so that when open, the straight wire may be inserted therein parallel with the members, then bent by the closing of the members, the ends of the wire still remaining parallel with the members, and be readily removed therefrom in bent condition. The member A may be held in a vise by inserting its lower flange parallel to eachother, which is done by clos shows a piece of wire having two bends, the

between the jaws, and by opening the member B, the wire may be inserted as described. Then by closing the member B, the wirewill be bent as shown in Fig. 1. In this way the member A and the long end of the wire may be held stationary in making the bend, which is highly advantageous.

What I claim is 1. In a wire bending device, two members pivoted together and provided with means to receive a straight wire when open, and to hold the ends thereof parallel with the members and to bend the wire by the closing of the members.

2. In a wire bending device, two members pivoted together at one end and provided.

I with means to receive a straight wire when open, and to hold the ends thereof parallel with the members and to bend the wire by the closing of the members.

3. In a wire bending device, two members pivoted together and provided with a looping pin and means to hold the wire in contact therewith, whereby the ends of the wire will be held parallel with the members and be bent by the closing of the members.

4. In a wire bending device, two members pivoted together and provided with a looping pin and wings to hold the wire in contact therewith and its ends parallel with the members, whereby it will be bent by the closing of the members.

5. In a wire bending device, two members pivoted together and provided with a looping pin and each of them with a wing to hold the wire in contact therewith and its ends parallel with the members, whereby it will be bent by the closing of the members.

6. In a wire bending device, two members pivoted together, a pivot-bolt engaging the said members formed with a looping pin upon one end, and means to hold the wire in contact with the looping pin and its ends parallel with the members whereby it will be bent by the closing of the members.

7. In a Wire bending device, two adjacent members, one of which is provided with a bifurcated end and the other with an end fitted to enter and hinge in the recess between said bifurcated ends, means to pivot said ends together and means to receive a straight wire when the members are open and to hold the ends thereof parallel with the members and to bend the wire by the closin of the members.

8. l n a wire bending device, two adjacent members, one of which is provided with a bifurcated end and the other with an end fitted to enter and hinge in the recess between said bifurcated ends, a rivet or bolt to pivot said ends together, one end of said bolt or rivet being extended beyond the upper face of the bifurcated end and forming a looping pin and means to hold the wire in contact with said pin and its ends parallel with the members whereby it will be bent around the pin by the closing of the members.

9. In a wire bending device, two adjacent members, one of which is provided with a bifurcated end and the other with an end fitted to enter and hinge in the recess between said bifurcated ends, a rivet or bolt to pivot said ends together, one end of said bolt or rivet being extended beyond the upper face of the bifurcated end and forming a looping pin and a wing on each of the members to hold the wire in contact with the looping pin and its ends parallel with the members whereby it will be bent around the pin by the closing of the members.

10. In a wire bending device, two men1- bers pivoted together and provided with means to receive a straight wire when open, and to hold the ends thereof parallel with the members and to bend the wire by the closing of the members and a handle attached to each of the said members.

11. In a wire bending device, two members pivoted together and provided with a looping pin and means to hold the wire in contact therewith and its ends parallel with the members, whereby it will be bent by the closing of the members and a handle attached to each ofthe said members.

12. In 'a wire bending device, two members pivoted together and provided with a projection and means to hold the wire in contact therewith and its ends parallel with the members, whereby it will be bent by the closing of the members.
