Description

A. T. LARGE, OF TOMAH, WISCONSIN.

IMPROVEMENT IN SAFETY-POCKETS.

Specification forming part of Letters Patent No. 59,415, dated November 6, 1866; antcdatcd October 27, 1866.

To all 'whom it may concern.-

Be it known that I, A. T. LARGE, of Tomah, in the county of Monroe and State of Wisconsin, have invented a new and Improved Clasp for Safety-Pockets; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming part of this specification.

My invention consists in a clasp to be ap plied to the mouth of the pocket, which is selflocking, but which may be unlocked quickly and without diihcnlty, the whole being concealed from view.

In the accompanying drawings, Figure l is a side View of my safety-clasp for pockets. Fig. 2 is an end View of my clasp. Fig. 3 is an inside View of the clasp, with the top removed, on the plane of the line .fr a', Fig. 1.

Similar letters of reference indicate like parts.

A A designate, respectively, the two jaws of the clasp and these are composed of metal, and are pivoted together at the lower ends, and they externally present somewhat the appearance of a satchel or carpet-bag clasp.

B (refer to Fig. 3) is a rod carrying on its inner end a catch, c, and on its outer end a small knob, b, against which to press in nnlocking the pocket. This rod slides in bearings at one end in the end plate of the jaw B,

and at the other end in a lug or standard, c,

secured to the inside of the side plate of the frame1 and it has coiled around it a spiral spring, d, one end of which rests against the lng c, and the other against a collar, c, upon the rod. The tendency of the spring is to keep the rod thrown out, so as to bring the catch np close to the lu g, and this causes said catch to engage with another catch, f, secured to the opposite jaw of the clasp. These parts are so arranged relatively with each other that the clasp will always be locked, and that to nnlock it it is necessary to press upon the knob t and cause the rod B to slide longitudinally, and this carries the catch c ont of the way of the other catch, f, and thus enables the pocket to be opened.

O is a bent spring carrying a hook, g, upon its end, and so arranged that when it is de sired to keep the clasp unlocked it can be made to lock the catch a', and thus, prevent it from coming in contact with the catch f, as shown in red outline in Fig. 3, and it is operated by a pin, h, passing throngha hole in the side of the frame, and accessible to the hand of the wearer of the pocket. It is intended to have this clasp attached to an india-rubber pocket, or one made of sonne other material, and when it is properly inserted in the pants the rod B passes up through the waistband of the pants, and is thus concealed, and yet handy of access to the wearer of the pocket.

By this invention I produce a clasp for a pocket which is entirely concealed, light in weight, cheap of construction, and reliable in all respects as a protection against picking a pocket by putting the hand in the mouth thereof, which is a common way of pocketpicking.

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

1. The combination of the rod B, spring d, catch j, and jaws AA', substantially as specilied.

2. The combination of the spring O with the pin it, catch a, rod B, and catch f, substantially as specified.
