UNITED STATES PATENT OFFICE.-
GEORGE H. DRAPER, OF NORTH ATTLEBOROUGH, MASSACHUSETTS, AS- SIGNOR TO HIMSELF AND OSCAR M. DRAPER, OF SAME PLACE.
IMPROVEMENT IN CHAIN-HOOKS.
Specification forming part of Letters Patent N0. 38,532, dated May 12, 1863.
To all whom it may concern:
Be it known that I, GEORGE H. DRAPER, a resident of North Attleborough, in the county of Bristol and State of Massachusetts, have invented an Improved Chain-Hook or Connection; and I do hereby declare the same to be i'u'ly described in the following specification and represented in the accompanying drawings, of Which- Figure 1 is a side view, Fig. 2 an end view, and Fig. 3 a longitudinal section, of it. Figs. 4 and are side views of its tongue and shank, and show the scarting the; eof.
The device on which my improvement is founded is a contrivance well known for the attachment of a guard-chain to a Watch.
It consists as follows, viz., of a swivel-rin g, a a, ahalf-screw, b, a screw-nut, c, a curved shank, d, and a movable tongue, e, terminating in a semi-screw, f, the several part-s being arranged with respect to each other as shown in the drawings.
Instead of making the tongue e withl an auxiliary tongue at its lower end to enter a corresponding recess formed in the shank d and connect-ing the two by a rivet or hingepin passed at right angles through them, I form each of them with a scart` or bevel, as shown at g or h in Fig. 2, and lap one of such scarfs or bevels on the other; and, instead of passing the connection rivet or pin t' through the two, so as to be perpendicular to their sides in the usual manner, I bore its hole either a little inclining to the ends, (see Fig. 2, wherein the hole is represented by dotted lines,) or at right angles to the scarting. On insertion of and fastening the pin in place the tongue Will be capable of being moved on it, so as to carry its semi-screwr f at the proper distance beyond the semi-screw b, for the purpose of either attaching the chain-hook to or detaching it from a Watch or other article. This mode of constructing the chain-hook has the merit of simplicity and cheapness, and it renders the hook quite as strong, if not stronger, than the old plan of interlocking them by a common hin ge-joint.
I claim- The improved chain hook or connections as made With its shank and movable tongue scarfed together in manner, and secured by a rivet or pin arranged with respect to the scarfing, substantially as described.

HENRY RICE, H. W. DEAPER.
