IMPROVEMENT IN SNAP-HOOKS.

Specification forming part of Letters Patent No. 39,670, dated August 25, 1863.

To all whom it may concern Be it known that l, NORMAN NORTH, of Middletown, county of Middlesex, and State of Connecticut, have invented certain new and useful Improvements in the Manufacture of snapHooks; and I do hereby declare that the saine is described and represented in the following' specification and drawings, and to enable others skilled in the art to make and use the same, I willproceed to describe its construction, referring to the drawings, in which the same letters indicate like parts in each of the figures.

The nature of said improvement will be fully understood from the specification and drawings, in Which- Figure l is a perspective View. Fig. 2 is an edge View. The loop, a portion of the 200k, its latch and spring, are shown in seca is the hook. b is the latch. c is theloop, by which itis made fast to a strap. d is the spring, which is tted and secured at one end by a pin or screw into a recess on the outside and around the heel end of the hook, so as to appear4 ush with the outside of the hook. The latch b is secured to the heel of the hook by a hinge-joint, e, and that portion of the latch which is tted into and forms part of the joint is flattened, so as to produce a leverage for the spring to act against and cause it to press firmly against the V-shaped seat in the end of the hook at g, and is, or may be, of such shape as to allow the latch to be set or fixed, or nearly so, when pressed inward from its position indicated by the line to that indicated by the line This spring, being iitted upon the outside of the hook, renders it cheaper and more easy of manufacture, less lia-ble to become choked by dust and dirt, whereby it would become inoperative. Ihus I am enabled to produce an article cheaper, more durable, and tasteful in its appearance, and less liable to get out of order. l Y

I believe I have shown the nature, construction, and advantage of this improvement, so as to enable others skilled to make and use the. same.

What I claim, therefore, and desire to secure by Letters Patent, is-

As a new improved article of manufacture-A Viz., the arrangement of the spring d, fitted and secured in a recess in the outside of the heel of the hook a, for the purpose of operating the latch b, substantially in the manner and for the purpose described.

NORMAN N OR'IH.
