ALFRED J. THOMSON, OF CANTON, MASSACHUSETTS.
LEATHER-STRETGHING-STRING CLAMP.
Specification of Letters Patent.
Patented March 3, 1908.
Application filed June 24. 1907- Serial No. 380.565.
To all whom it may concern:
Be it known that I, ALFRED J. THOMSON, a citizen of the United States of America, and resident of Canton, county of Norfolk, State of Massachusetts, have invented certain new and useful Improvements in Leather-Stretching-String Clamps, of which the following is a full and clear specification, reference being had to the accompanying drawing, in which.
Figure 1 is a perspective view of my device applied to the bar of a leather-stretching frame; and Fi g. 2 is an end elevation showing the bar in cross-section.
The object of this invention is to provide a simple cleat or clamp for holding the free ends of the strings used in holding a piece of leather stretched in a frame. It is now customary to fasten the ends of these strings to nails or tacks driven in the frame or bar, and this method being obviously slow and insecure I have devised a cleat to take the place of the nails whereby the strings may be more readily connected to the frame bar and will be more securely held taut, as more fully hereinafter set forth.
My device, in its preferred form, is 0011- struoted of a single piece of suitable wire bent to form two separated parallel pointed entering members a, a, a pair of clamping members I), l), and a cross-bar a connecting the two upper members or arms of said clamps. The two clamps consist each of, two parts I), b,lying one above the other and connected together at their outer ends by the bend in the wire, the upper part being resilient and terminating short of the inner end of the lower part and said lower part being connected at its innerend to the upper end of its entering member. The two members of each clamp are separated sufficiently to permit a string to be inserted between them and be clamped therebetween by being pulled toward the bend or outer end of the clamp. The two upper members of the clamps are connected at their inner ends by the cross part c, and the sharpened entering members a, are curved downwardly and outwardly.
In securing the string to the clamp the free end of the string is simply looped into both clamps as shown and pulled forward under the resilient members of the clamp until the said members bite the string. The string is thereby clamped at two points and at both points the clamping action is between the members of the clamp and not against the wood bar. In this way it will be observed that the strings may be readily fastened and by reason of the action of the connected pair of clamps the string will be held securely.
Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is
A string-holding cleat formed of a single piece of wire bent into shape and comprising a pair of separated clamps each consisting of a pair of members one arranged directly above the other and the upper one being resilient, each of these pairs of members being directly connected at their inner ends and separated at their outerends to form outwardly opening clamping aws, a pointed entering member carried at the outer end of each of the lower members, and a cross-bar directly connecting the outer ends of the upper members, substantially as set forth.
In testimony whereof I hereunto afliX my signature in the presence of two witnesses this 21st day of June, 1907.
ALFRED J. THOMSON.
Witnesses J H. LANDIOK, THERON M. KELLEY.
