Specification of Letters Patent.

Patented March 3, 1908.

Application filed April 18. 1906- Serial No. 312.397.

T 0 all whom it may concern:

Be it known that we, JosEPH G. BERTHI- AUME and ARTHUR E. BARLOW, citizens of the United States, residing at Worcester, in the county of Worcester and State of Massachusetts, have invented a new and useful Implement for A plying Clam s to Wire Fences and the Like, of which t e following is a-speciiication.

Our invention relates to an implement especially designed for applying sheet metal clam s to fences and other fabrics but it is capa le of general use for exerting pressure in a certain way. The particular kind of fence to which it is especially adapted is made by placing a bent clamp or clip over one wire, passing the other wire through slots in the clip, and then flattening out the clip in such a manner as to ofl-set both wires and form a stiff joint.

The principal objects of the invention are to provide means for performing this operation which will be convenient in operation, simple in construction, durable and substantial, and to avoid the decrease of the throw of the jaw which takes lace in implements which are now used 'or this purpose after they have been used for some time.

Reference is to be had to the accompanying drawings in which,

Figure 1 is a side elevation of an implement constructed in accordance with the principles of our invention. Fig. 2 is a similar view on an enlarged scale with parts removed to show interior construction. Fig. 3 is a bottom plan view. Fig. 4 is a perspective view of a link which we prefer to employ. Fig. 5 is a perspective view showing the clamp or clip applied to the wlres and ready to be operated upon by this implement, and Fig. 6' is a front elevation of the 7 same.

We have shown the implement as comprising a body a from which extends an off- 7 drawn. The projection a is provided with a depression a on its inner surface to receive the edge of the clamp or clip 10 upon which the implement operates.

For the purpose of engaging the clamp or clip and forcing it into the proper position, a movable jaw c is mounted opposite the stationary jaw b. This movable jaw is provided with a groove 0 which has an off-set portion 0 to permit a bend in the wires of the fence to allow them to pass over the transverse wires. The jaw 1s mounted on a slide (1. This slide works in ways e on the body a. The body is provided with a rearwardly extending rojection or stationary arm f which has a Fandlef. A lever 9 extends in the same general direction as the projection f. It carries a handle 9 adapted to cooperate with the handle f. The lever g is pivoted on a stud h and it is provided with a forwardly extending portion 9 which ispivotally connected with a link is which in turn is pivotally connected with the slide. It will be seen that the swinging of the lever g about its ivot will, through the instrumentality of the link, force the slide and movable jaw forward and back with a great leverage. In the present instance, we have shown the link as'being provided with two cylindrical or spherical ends It which fit in corresponding sockets g and d in the arm 9 of the lever and the rear of the slide. Covering these elements is a plate m which is secured to the body of the implement.

By constructin a tool in accordance with the principles set 'orth above, whether in the form shown or otherwise within the limits of our claims, an implement is secured which while giving a great leverage, is not susceptible to any changes due to wearing of the bearing surfaces.

It will be noted that when the arts are positioned, as shown in full lines in i 2, the two axes on which the heads of the ink are pivoted and the center of the pivot h are nearly in alinement but not quite so; in other words, the entire throw of the lever is not taken up and as the center one of these three points is slightly out of alinement with the other two, when the lever is moved toward the dotted line position, the parts will be drawn back in an obvious manner, there being no dead center to overcome.

We are aware that many changes may be made in the implement by any person skilled in the art without departing from the scope of our invention as expressed in the claims.

Having thus fully described our invention, what we claim and desire to secure by Letters-P atent is 1. In an implement for applying clamps to wire fences and the like, the combination of a body having an arm, a handle on said arm, a jaw located on the body opposite the arm, a second. aw adapted to move toward and" from the first-named jaw, a slide on which the second jaw is mounted, said body having ways along which the slide is adapted to move, said slide having a socket, a lever pivotally mounted with respect to the body and havinga handle adaptedto move towards and from the first-named handle, said lever having its socket located on the side of its ivot opposite to that on which its handle is lbcated, and a link having means located in said sockets by which said link is pivotally connected with the lever and with the second jaw, the points at which the link is pivoted to the lever and to the jaw and at which the lever is pivoted to the body being sub stantially in alinement when the jaw is at the end of its stroke.

2. An implement for applying clam s to wire fences and the like, comprising a body having a stationary arm, a handle on said arm, a stationary jaw located on said body opposite said arm, a movable jaw on the body, a lever pivoted to the body, a link pivotally connected with the lever and with the movable jaw, and a handle on said lever adapted to move toward and from the first named handle, the points at which the link is pivoted to the aw and to the lever and at which the lever is pivoted to the body being nearly in alinement when the jaw is at the end of its stroke, the lever and arm being nearest together at the same time.

3. In an implement of the character described, the combination of a body having a stationary arm provided with a handle and a stationary jaw, a second jaw adapted to move toward and from the stationary jaw, a

slide on which the second jaw is mounted,

said. body having ways along which the slide is adapted to move, said slide having a socket, a lever pivotally mounted on the body and having a handle adapted to move toward and from the first-named handle, said. leverhaving a projection provided with a socket located on the side of its pivot opposite to that on which its handle is located, and a link having two cylindrical heads, one located-in each of said sockets.

In testimony whereof we have hereunto set our hands, in the presence of two subscribing witnesses.
