Specification of Letters Patent. 5 Patented 1y 30 1918 Application filcd March 2, 1917. Sria1No.'152,025.

Z '0 all whom it may concern:

Be it known that I, FRANK E. BEAZELL, a citizen of the United States, residing at Speers, in the county of Washington and State of Pennsylvania, have invented oertain new and useful Improvements in Wire- Clamps, of which the following is a specifi cation.

This invention has reference to means for clamping wire, and its object is to provide a device of this character which is especially adapted for use in a wire mill to engage and clamp a strand of wire to the reel from which several lengths of wire are'being unwound and out.

To this end my invention. consists in the construction and arrangement of various parts illustrated in the accompanying drawings and described more fully in the following specification.

In the drawings: 7

Figure 1 is a view in side elevation,

Fig. 2 is a front view illustrating the mannor in which the clamp is attached to a brace rod of a wire reel.

Fig. 3 is a side view, partly in section to disclose the plunger,

Fig. 4 is a sectional view taken through the plunger, and Fig. 5 is a detail view of thedclamp and the reel with which it is use Referring now more particularly to the drawings, it will be seen that my invention includes a pair of oppositely disposed plates 1 and 2 having each a rear edge 3 which tapers gradually toward the upper end 4;, thus narrowing the plates at their uppermost ends, but widening out an intermediate portion such as 5, from which point the rear edges 6 taper inwardly again but in a downward direction as shown to advantage in Figs. 1 and 3 of the drawings. Each plate has a portion of its lower end removed in proximity to the tapering edge 6 to provide hook-arms 7. The plate 2 has further provided an elongated vertically extending opening 8 provided therein, the purpose of which will be hereinafter explained. The plates 1 and 2 are spaced from each other by a block 9 to which the plates are securely fastened by means of four or more rivets or bolts 10.

This block 9 is provided with a vertical extending bore 11 through which is guided a plunger rod 12. To the lower end of the rod 12 1s secured a gripping block 13 having teeth 14. provided upon its underface so as to firmly grip the wire strand 15 when the latter is caught between the block 13 and the rod 16. The upper end of the plunger is bent into hook shape whereby it may be attached to the cam lever 17. Although this end of the plunger may be formed in any manner suitable for the purpose, as represented by the drawings it consists of a right-angular extension 18 which is adapted to project through the slot 8 in the said plate 2 and which carries a vertical hook 19 which by its abutment with the upper and lower walls of the slot limits the movement of the plunger through the bore 11.

Between the plates 1 and 2 at their upperends 4 is the cam lever 17 which has the conventional handle portion 20 and the cam shapedhead 21 which is pivotally mounted upon the bolt 22 as indicated. Lying adja' cent to the forward or working edge 23 of the cam head and extending in arcuate conformity therewith is a slot 24 into which projects the bill 25 of the plunger hook 19.

Upon moving the handle 17 from the position shown in dotted lines in Fig. l to the position in full lines theedge 23 of the cam lever, working upon the angle extension 18 of the plunger rod and in the recess 26 thereof will cause the plunger to move downwardly to clamp the wire strand l5 and upon reversing the handle, the action will be otherwise and the wire strand will be released. V

The nature and purpose of the clamp will perhaps be more fully understood and appreciated by reference to the particular type of reel to which my clamp is adapted. As

ported in a horizontal position and has'the drum portion formed of a plurality of rods 16, about which the wire 15 is wound. The reel tapers toward its outer end so that as the wire is fed thereto over the pulley 28, each coil works toward the smaller end in spaced loose convolutions which may readily be pushed to one side when the clamp is to be attached to one of the reel rods 16. The weight of the handle 20 serves to maintain the plunger rod 12 in constant engagement with the strand 15, and the pressure exerted by this action also serves to clam the rod 16 to the twin bills 27 of the hoo -arms 7, whereby the clamp is also retained in engagement with the wire reel by the same acinvention and in the proportion, and 'arrangement of parts as may fall within the scope "ofthe appended claims and-without sacrificing any of the advantages thereof.

Having fully describedr'ny invention what I claim as new and desire to secure by Let ters Patent 'is:-- e

1. In a wire clamp, the combination with spaced plates having twin hooks at their lower: ends and one of them having an up right "slot, and a longitudinal guide between said plates and interposed between the hooks and the slot of a plunger-slidably mounted in said guide and having a. gripping-block at its low'er'end and its upper end extended laterally into said slot and thence upward therein I and thence again inward, a pin through the plates above said slot, and a lever 'whose head is piv'otally mounted on said pin and slot-ted to produce an eccentric 3- working-edge standing between the lateral portionsof said plunger, as described.

2. In a wire clamp, thecombination with spaced" plates having twin hooks at their lower endsand one of them having an upright slot, a block between said plates having a guide, and a cam journaled between the upper'ends of said 'plates; of a plunger movable in said guide and having a gripping block above said twin hooks, the upper end of the plunger having a lateral extension movably mounted in said slot and a hook engaging said cam.

3. In a wire clamp, the combination with spaced plates having twin hooks at their lower ends and one of them having an upright slot, a block between said plates having a guide, and a cam journaled between the upper ends of said plates and having-u working edge; of a plunger. movable in said guide and having .a gripping block above said twin hooks, its upper end having a lateral extension underlying -said working edge and projecting into and movable withinsaid slot, and an upstanding hook at theouter end of'said extension and provided with a bill overlying'said working edge.

Intestimony whereof I aiiix my signature in presence of two witnesses.

FRANK E. BEAZELL.
