slur HOOK.
App lication'filed July 7, 1925. Serial No. 42,065.
I To all whom it may concern:
Be it known that 1, JOHN A. Fraser:-
a cltizen of the United States, re- Connell, in the county of Franklin and State of Washington, have invented certainnew and useful Improvements in'Sna-p Hooks, of which the following is a specificainvention relates to improvements in hooks and more particularly to lockthe same; j i It is an object of 'theinvention'to provide a hook having aspring pressed plunger for closing the hook opening and means for locking the plunger against movement to prevent accidental opening. of the hook.
A further object of the invention is to provide a device ofthe above-mentioned chary snap acter which is simple and durable in con struction, reliable and eflicient in operation and inexpensive to manufacture.
Other objects and advantages of the invention will be apparent, during the course of the following description.
In the accompanying drawing-forming a part of this specification and in which like numerals are empolyed to designate like parts throughout the same.
Fig. 1 is a side elevation of my improved snap hook,
Fig. 2 is a longitudinal sectional view of the same, and,
Fig. 3 is a perspective view of the locking lever.
In the drawing, wherein for the purpose of illustration I have shown a preferred embodiment of my invention, the hollow body or shank 5 is closed at both ends, having an integral loop 6 at one end and an integral hook 7 at the opposite end. A spring pressed plunger 8, slidably mounted in the body, is adapted to extend through an the end nearest the hook and engage the free end thereof, to close the gap between the hook and body. A coil spring 10 having one end bearing against the end of the body and its opposite end against the end of the plunger, normally retains the latter in a locked position. The spring is held in place by the opposed pins 11 which project from. the end of the plunger and the end of the body, entering. the convolutions of the spring. A knob 12 'is formed integral with the pin 13 projecting from the plunger, and movable in the slot 14 through the body, whereby the plunger may-beretracted toopen the hook. i v
To prevent accidental opening ofthe ghook a locking means 1s provided consistingof' a lever .15 journaled on the transverse pivot 16 mounted in the sides of the casing 17 cast integral with the outside of'the body. The forward end of the lever is"forked,""at as 18, being curved downwardlyand extending through an opening 19 in the body.
The forked end engages an annular groove.
20, formed adjacent the rear end-ofthe plunger 8' holding the plunger against retraction until'released. The oppositeiend of the lever 15 is bifurcated, as at 21, to receive the lower end of the push button 22 ,which is connected therewith by the pivot pin 23. The upper end of the push button extends through an opening 24:, projecting above the top ofthe casing. A spring 25 is. mounted between the body and rear end of the lever normally holding the latter in a locked position. i
In use, the gap between the hook and shank is normally closed by the spring pressed plunger having means for manually retracting the plunger to open thehook. To prevent accidental opening of the hook the forked end of the locking lever engages the annular groove in the plunger holding the same against movement.
To release the lever, the push button connected therewith is depressed, lifting the forked end out of the groove and thereby, permitting the plunger to be retracted to :openthe hook.
. It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same and that certain changes in the shape,
size and arrangement of parts may be resorted to without departing from'the spirit of the invention or the scope of the subjoined I claims:
Having thus described my invention I claim:
1. In a snap hook, the combination of a hollow body having a hookformed at one end, a spring pressed plunger slidably mounted in said body adapted to abut the free end of said hook, an annular groove. formed'adjacent the rear end of said plunger and a forked lever pivotally mounted in said body adapted to releasably engage the groove in said plunger. 7 I
2. In a snap h k, the combination of a having a forked end adapted to releasably' engage the groove in said plunger, and means for releas ngsaid lever.
3. In a snap hook, the combination of a hollow body having a hook formed at one end, a spring pressed plunger slidaibily mounted in said body adapted to abut the free end of said hook, an annular groove formed adjacent the rear end of said plunger, a casing formed integral with the outside of said body and having communication therewith, a lever, pivoted in said casing having a forked end adapted to releasably engage said groove, spring means for normally holding said lever in engagement with said groove and means for releasing said lever. H r c 4. In a snap hook, the combination of a hollow body having'a hook formed at one end, a spring pressed plunger slidably mounted in said body adapted to project through one end of the body and normally abut the free end of said hook, a casing formed integral with the outside of said body having communication with the interior thereof, a locking lever pivotally mounted in said casing having its forward end curved downwardly into the body, said forward end being forked and adapted .to engage the groove surrounding the rear end of said plunger, springs means for normally holding said lever in engagement with saidplunger and means connected with the rear end of said lever, extending through said casing for releasing said lever.' v
In testimony whereofI afliX my signature.
