GEORGE W. II. SCHREFFLER= OF LOCKHAVEN, PENNSYLVANIA.
SPECIFICATION forming part of Letters Patent No. 697,367, dated April. 8, 1902.
Application filed November 1, 1901. Serial No. 80.816. (No model.)
A To @ZZ whom, t may concern:
Beit known that I, GEORGE W. H. SCHREE- FLER, a citizen of the United States,'and a resident of Lockhaven, in the county of Clinton and State of Pennsylvania, have invented a new and Improved Snap-Hook, of which the following is a full, clear, and exact description.
This invention relates to a snap-hook in which it is sought to avoid the usual button attached to the pin and serving as a means for pushing the pin back against the spring. This button is inconvenient in operation and also is very liable to breakage, which latter condition when it occurs renders the hook useless. shield outside of the casing in which the pin slides and connecting the shield with the pin in a certain manner hereinafter specified, so that pressure applied to the shield will be communicated to the pin. This arrangement not only overcomes the disadvantages mentioned above, but it presents the further advantage of preventing water entering and freezing in the casing, and thus .clogging the pin.
This specification is a specific description of one form of the invention, while the claim is a deinition of the actual scope thereof.
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.
Figure l is a top plan view of the invention. Fig. 2 is a side elevation, parts being in section; and Fig. 3 is a section on the line 3 3 of Fig. 2.
a indicates the hook proper.
li indicates the eye, and c indicates the` shank connecting the parts a and b, which shank is tubular to form the casing wherein the pin dis mounted to slide toward and from the bill of the hook. v
j The parts a, b, and c are constructed of an integral mass ofmetal in the usual manner, parts of the shank c being bent upward and toward each other to give the shan-k its tubular form.
e indicates the spring which sets in the cas; ing behind the pin and pushes it toward the hook.
Formed `on the pin d and projecting laterally therefrom is a stud f, which slides freely in a slot c in the walls of the shank c, this I attain this end by locating a` i stud projecting beyond the shank and having the shield g formed integral therewith. This shield is outside of the pin-casing, its front end terminating approximately at the front end of the pin. After the pin is in place the side or skirt portions of the shield are bent down to give the shield a shape conforming to that of the casing.
The parts d, f, and g are all formed inte gral with each other, the shield being of such metal that its skirts may be bent in the manL ner specified. The shield is formed with an enlargement g just opposite the stud f and also with an annular bulge g2 adjacent to its rear end. These projections g' and g2 form gripping devices to facilitate the operation of the hook.
Now it is clear that from this construction the pin may be easily operated even with a gloved hand or in cold weather when ones fingers are numb. It will also be seen that the shield protects the other parts and prevents the entry of rain or sleet into the casing to freeze and clog the pin.
Various changes in the form, proportions, and min or details of my invention may be resorted to without departing from the spirit and scope of my invention. Hence I consider myself entitled to all such variations as may lie within the scope of my claim.
Having thus described my invention, I claim as new and desire to secure by Letters Patent- A snap-hook, comprising a hook proper, a
tubular shahk to which the hook is joined, a
- pin sliding in the tubular shank to meet the bill of the hook, the shank having a longitu- `dinal slot therein, a stud carried by the pin and projected through the slot, and a shield lfastened to the stud and inclosing the major part of the shank, said shield extending longitudinally with the shank and being curved down around the sides thereof, and the shield moving with the pin toward and from the bill.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
GEORGE IV. SCI-IREFFLER.
