WILLIAM H. MOGREW, OF PERU, INDIANA, ASSIGNOR OF TWO-FIFTHS TO JOHN MYERS, OF SAME PLACE.

SNAP-HOOK.

SPECIFICATION forming part of Letters Patent No. 332,415, dated December 15, 1885,

No model.)

To all whom, it may concern:

Be it known that 1, WILLIAM H. MOGREW, a citizen of the United States, residing at Peru, in the county of Miami and State of Indiana, have invented a new and useful Improvement in Snap-Hooks, of which the following is a specification, reference being had to the accompanying drawings. My invention relates to an improvement in [c snap-hooks; and it consists in the construction, combination, and arrangement of parts, substantially as hereinafter set forth, and. specifically pointed out in the claims.

My invention has for its object the provision of a snap-hook which can be easily and conveniently operated to quickly] attach and disengage the device to any part of the harness, and which shall be free from liability to be disengaged therefrom, and to combine strength and durability of construction with thorough effectiveness of operation.

In the accompanying drawings, Figure l is a perspective view of my improved snaphook. Fig. 2 is a longitudinal vertical sectional view on the line .90 as, Fig. 1. Fig. 3 is a transverse section on the line y y of Fig. 2, looking in the direction indicated by the arrow. Fig. 4 is a perspective view of a modification.

Like letters of reference indicate corresponding parts in the several figures of the drawings, referring to which- A designates my improved device, which consists, essentially, of abuckle, B, and hook O, the peculiar construction and arrangement of the several parts of which are as follows:

The buckle B comprises two side bars, b b, arranged in a vertical plane at a short distance from each other, two parallel cross-bars, b,arranged at the outer ends of the side bars, on the upper and lower surfaces thereof, to provide a loop, N, for the passage of a strap, D, to be connected to said buckle, and a crossbar, b arranged a short distance from the bars 1) within the plane of the side bars, and having a tongue, I), over which the strap D is passed and bent or lapped upon itself and passed between the bars I)", while the tongue 1) passes through an opening in said strap. 50 The tongue b is shown arranged in a horizontal position; but it may project upwardly in an inclined position, if preferred. The forward ends of the side bars, I), of the buckle are curved inwardly toward each other, and connected by a flange, 0, extending from one to the other,and arranged on the plane of the lower edges thereof, and by vertical walls 0 flaring outwardly from each other, and pro- 7 Viding guides for the arm (1 of the tongue E to the snap-hook, as will presently appear.

The snap-hook 0 comprises a curved hook, 0 which projects from the inclined walls or guides c, and is bent over upon itself to provide an arm, 0 the inner end of the arm or hook 0 being made hollow, as at 0 for a portion of its length, and which communicates with the spaces between the flaring guide- Walls, the tongue or arm of the keeper or tongueE of the snap-hook being arranged to pass within the said opening a".

The tongue or keeper E comprises a curved arm, 01, and a finger-piece, d", arranged at an angle thereto. The arm 01 is curved in the arc of a circle concentric with the curved hook O, and the lower end thereof is fitted in 7 the recess c,while the upper end bears against the extreme forward end of the hook C. Said arm (I is arranged between the Vertical walls a, and is free to move or slide between them and within the socket c in the curved hook to open and close the ring to permit hooks, buckles, 850., to be connected thereto. The flaring walls 0' serve as guides to the sliding arm d and to the operators fingers in manipulating the device to attach or detach it, as desired.

F designates a coiled spring arranged within the chamber or opening 0* in the hook c, and hearing at one end against the inner wall thereof, and at its opposite end against the arm d of the tongue E, to keep the same normally pressed outward and in contact with the arm 0 of the hook O, as will be readily understood.

The various side and cross bars of the buckle B, the vertical flaring guide-walls c, and the hook c are all cast or formed in one piece for simplicity, strength, lightness, and durability, and the arm (I and finger-piece d are also cast or formed in one piece, thus making the com- 100 plete snap-hook in three pieces-the buckle and hook, the tongue thereto, and the spring which are so arranged and put together as to present a neat and compact appearance, and Very durable and strong in construction, and easily and conveniently operated.

The arm 01 of the tongue moves inwardly within the plane of the hook 0 when operated, andit is normally housed within and protected from breakage or damage by the vertical flaring walls a and the recess.

In the device shown in Fig. 4 the buckle B is dispensed with, and in lieu thereof asingle loop, G, is employed, around which the strap D is passed; but I prefer to employ the buckle B, for the reason thata convenient and simple means is provided for detachably connecting the device to astrap.

Various slight changes in the form or proportion of the parts can be made without departing from the principle or sacrificing the advantages of my invention, the essential features of which will be readily understood from the foregoing description, takenin connection with the annexed drawings.

I claim as my invention- 1. As an article of manufacture, a snaphook having a buckle and the flaring guidewalls c,cast integral therewith, and provided with a curved socket, c asliding tongue, E, arranged between the guide-walls and having a finger-piece, and a spring seated in the socket and bearing againstthe tongue to keep the same normally in engagement 'with the hook,
