WIRE-BENDING DEVICE.

SPECIFICATION forming part of Letters Patent No. 548,263, dated October 22,1 895. Application ilcd January 8, 1895- Serial No. 534,255. (No inotlel.)v

" stay or brace therefor.

The object of the present invention is to improve this class of instruments and to provide a device by which the crimping may be performed upon the application of less power and consequently with greater ease. The invention also contemplatesa device which may be made rigid with a table or bench, so that one section may move upon another and the bending or crimping of the wire be thereby effected.

Still further, an object is to combine with the bending apparatus an improved wire-cutter, by which the wire may be divided into requisite lengths by the same instrument which forms the bends therein.

To these several ends myinvention consists in a main or base section provided with screwholes for permitting it to be rigidly secured to a table or bench and having near one end two transversely-aligned lugs, which carry a pin or spindle for mounting the tongue of a movable section in place. The base-section also has a knife-edge formed directly adjacent to one of the lugs, and which cooperates with a corresponding knife-edge formed as a contin uation of the tongue on the swinging section. The bending is performed by means of a tenon or like projection formed on the under side of the movable section and adapted to move into an enlarged recess or opening formed on the base-section.

In the accompanying drawings, Figure 1 represents a perspective view of an instrument constructed after the manner of my invention. Fig. 2 is avertical longitudinal section thereof. Fig. 3 is a cross-section taken on the line a: a: of Fig. 2, the Wire being shown in the proper relation thereto. Fig. 4 is a section on the line y y of Fig. 2. Fig. 5 is a side elevation of the device, the movable section being shown raised. Fig. 6 is a view illustrating the wire as bent by my improved instrument. Fig.7 is a detail perspective view illustrating a wire-fence joint.

The reference-numeral 1 indicates the basesection, which is shaped as an elongated plate, and which has its ends formed with the screw or bolt holes 2, by which it may be rigidly secured in place.

3 indicates two vertically-extending and duplicate lugs, which are formed integral with the base-section 1, and which are transversely aligned with each other and carry the pin 4. The pin 4 extends horizontally through the lugs 3 and through the tongue 5 of the movable or swinging section 6. The movable section 6 has its main portion of a width equalv to the width of the section 1, while its free end is reduced to form a handle portion 7.

Formed integral with the base-section 1 and directly adjacent to and inward from the lefthand lug 3 is the knife-edge 8, which is a forward extension of the lug, andwhich projects up vertically, and which has its cutting-edge longitudinally aligned with the inner side of the lug 3. This knife-edge 8 is adapted to cooperate with a corresponding edge 9, formed on the movable section 6 and asa continuation of the tongue 5. Thus, as the section 6 swings in the operation of the device the edge 9 will stroke past the edge 8 and thereby perform a shear cut.

Rigidly secured to or formed integral with the under side of the section 6 is the longitudinally-elongated tenon or lug 10, which is so arranged on the section 6 that it will be capable of stroking through the correspondinglyelongated opening 1l formed in the section 1. Theopening 1l is of a size equal to about twice that of the tenon 10, and this variance is provided in order that the wire,

Ywhich is bent or crimped, may pass between the tenon and the sides of the opening.

In the use of my invention to form stays of the character referred to hereinbefore, the wire of which they are to be composed is passed across the base-section 1 and over the opening 11 thereof, the swinging lsection 6 having been first raised, so as to permit the wire to lie directly on the base-section. The bending or crimping is now performed by 2 y g y 548,263

moving the section 6 down upon the basesection, which will cause the tenon l() to stroke into the opening 11, carrying with it the wire and forming therein the bend, which it is the purpose of my invention to make. When the rst bend has been formed, the wire should be moved along the crimper or bender for the length which it is desired that the bends shall have between each other and the operation above described repeated, which will result inthe formation of a second bend, and so the'operation should be prosecuted until the wire has been supplied with the requisite number of bends, whereupon it may be severed from the unbent portion of the Wire by resting it on the knife-edge 8 and by bringing the section 6 down, so as to cause edge 9 to move past edge S. When this has been done, the operation of forming thev stay will be completed.

Fig. 6 shows the product of the operation of the instrument, and by means of said tigure the whole will be apparent. This stay is provided adjacent to each fence-wire with a crimp or bend for the reception of the fencewires, and the crimps or bends are compressed around them and are retained by means of wire ties, embracing the compressed crimps or bends and interposed between the body of the stay and the fence-wires. The wire ties 3o are constructed by means of the wire-bender and consist merely of a loop or bend, and in constructing such ties the wire is bent at one end and the ties are severed, being in the form of staples, as will be readily understood. 3 5

Having described the invention, I claim- A wire bending device, comprising a base, provided with a longitudinal opening and having adjacent to its rear end a pair ot perfoi-ated lugs, one of the lugs being extended 4o forward and forming a cutting edge 8, and the swinging section or lever having the tenon l0 to co-operate with said opening, and provided With a tongue pivoted between the perforated ears and elongated to co-operate with 45 the extension and the cutting edge thereof, and forming with the same a cutter, substantially as described.

In testimony that I claim the foregoing as my own I have hereto afxed mysignature in 5 the presence of two witnesses.

CHRISTOPHER C. MORGAN.
