INCORPORATED, OF OTTUMWA, IOWA.

WIRE-WORKING mPIEMENT.

I Specification of Letters Patent.

Patented July 18, 1909.

To all whom it may concern:

Be it known that I, CLARK J. SMITH, residin at Ottumwa, in the county of Wapello and tate of Iowa, have invented certain new and useful Im rovements in Wire-Working Implements, 0 which the following is a specification.

My invention relates to certain new and useful improvements in implements for cutting, forming and applying wire fastenings to ose pipe couplings and my invention has for its 0 ject to provided a simple and effectively constructed implement whereby a fastener wire may be bent into sha e while a second wire is applied to the coup ing and a third wire is being out.

The invention also has for its object to provide an implementwherein the fastener wire may be cut, bent and applied by one and the sanlie implement without the use of auxiliary too s.

More speeificallltv the invention embodies those novel deta' s of construction, combination and arrangement of parts all of which will be first described in detail and then he s ecifically pointed out in the appended c ims, reference being had to the accompanying drawings, in which Figure 1 is a perspective view showing how my invention may be used to simultaneously apply a wire to the coupling, form another wire and cut a third wire. Fig. 2 is a central, vertical, longitudinal section of the coupling, the parts being shown in one posi tion. Fig. 3 is a similar view, the parts being in another position. Fig. 4 is a top plan Fig. 5 is a vertical longitudinal section on the line 55 of Fig. 4. Figs. 6 and 7 are cross sections on the line 66 of Fig. 4, looking in the direction of the arrows :4: and y res ectively. Fig. 8 is a rear elevation of my implement. Fig. 9 is a detail perspective view of the main frame. Fig. 10 is a similar view of the sliding carriage. Fig. 1 1 is a detail erspective view of the wire clamping end of t e carriage.

Referring now to the accompanying drawings in which likeletters and numerals of reference indicate like parts in all of the figures, 1 designates the main frame which is provided with aT-shaped channel formed by the bottom 1*, sides 1 a and the bent over top edges 1 At the front of the frame 1 the sides Pare provided with alining depressions 1 that are curved as at 1 to form cam surfaces and the depressions 1 merge with depressions 1' 1n the opposmg faces of the bent over ends 1, as clearly shown in Fig. 9 of the drawings.

The bottom 1 near the front end is provided with perforations 1 which register with perforations 2 in the sliding carriage 2 to form a cutting mechanism. At the rear the main frame 1 is provided with a back plate 1 which carries an anvil 1 that has a groove 1 fora purpose hereinafter more clearly understood and the back plate 1 is provided with longitudinal alining apertures 1 through which the ends of the wire 'w may be passe The carriage 2 is provided on its upper face with rack teeth 2", the front ones of which are cut away, as at 2, to leave a space between the rack teeth 2 and the adjacent edges of the bent over ends 1 of the main frame 1, the space being slightly more than the-thickness of the wirew. The front rack member 2 is provided with slightly beveled ortions 2 to receive the wire w when it is ent into form to revent it slipping off the member 2". At tiie rear the carriage 2 has grooves 2 and a bearing lug 2 to which a cam grip lever 3 is pivoted at 3, the lever 3 having serrated cam surfaces 3 to enter the grooves 2. The grooves 2, it should be understood, aline with the apertures 1 in the back plate 1 of the frame 1 so that when the wires are projected through the apertures 1 they will project into the grooves 2 and may be grip ed by the cam lever as shown in Fig. 2 of tile drawings.

The main frame 1 has ears 1 through which the pivoted ends 4 of the lever 4 pass, the lever 4 being provided with a segment 4* to mesh with the rack teeth 2 so that as the lever 4 is manipulated to turn the segment 4 .on its axis the carriage 2 will be reciprocated in the frame 1.

In the practical application of my invention the wire is cut into a proximately the desired lengths, and it is tiien placed in the depressions 1 of the main frame 1, it being understood that the carriage 2 is drawn to its, backmost position. The lever 4 is then moved in the direction of the arrow in Fig. 2, causing the carriage to be forwardly directed, thus bringing the front rack tooth 2 into engagement with the wire and thereby carrying it along and causing it to be' bent into a U-shape. The wire rests in the depressions 1, as it is formed, while the cam surfaces 1 serve to raise the ends of the wire clear of the frame 1, as it is, being bent into the U-shape, so that the wire will lie adjacent to the teeth 2 in the cut-away portions 2 thereof. Upon moving the lever 4 in an opposite direction to turn the carriage 2 to its backward position, the formed wire willbe released. In forming the Wire the two legs of the U are not always of the same length so it becomes necessary to trim them off or they may be longer than is desired, and may need trimming off for that reason. In order to trim the wire to the roper length after it is formed into the U-diape, the ends are passed through the apertures 1 in the bottom 1 of the main frame 1 and through the apertures 2 of the carriage 2, it being understood that the a

ertures

2 and 1 are first brought into ainement. As soon as the Wire has been projected through such a

ertures

1 and 2 the desired distance, t e lever 4 is brought down to project the carriage forwardly, causing the wire ends to be cut or broken. After the wire has been formed into U-shape, it is bent around the hose coupling in the usual manner with the ends projected through the loops and the ends of the wire are then assed through the a ertures 1 and clamped by the clamp 3, after which the lever 4 is brought down to move the carriage forward. This brings the portion w of the wire into the saddle 1 and as the carriage moves forwardly the wire will be tightly drawn around the coupling.

As soon as the wire has been drawn taut the coupling is rolled around the anvil 1 until the wire is bent to hold it from slipping.

After which, the wire is released from the clamp 3, withdrawn and bent down by using the implement as a hammer in any desired manner. A Wire may be bent into a U shape while a second Wire is being cut and a third wire isbeing applied to the hose cougling, by one and the same movement of t e lever 4, as indicated in Figs. 1, 2 and 3 of the drawings.

From the foregoing description, taken in connection with the accompanying drawings, it is thought the complete construction, operation and advantages of my invention will be readily understood by those skilled in the art to which the invention appertains.
