SNAP HOOK Original Filed Feb. 12, 1932 Patented Jan. 23, 1934 Price SNAP HOOK I Gilbert W. Stowell, Mackinaw, Ill.

Application February 12, 1932, Serial No. 592,463 Renewed May 26, 1933 10 Claims. (01. 24236) My invention relates more particularly to snap hooks intended primarily for use upon rain coats and similar garments and particularly those garments worn by firemen, though of course it is not limited to such use but may be advantageous-- 1y used for a variety of other purposes as will be apparent to those skilled in the art to which my invention appertains.

One object of my invention isthe provision of a hook which may be engaged or disengaged by the use of one hand only.

Another object of my invention is the provision of a hook, which, when its ring or eye is engaged therewith, issafe against accidental engagement with hanging wires or othersimilar conditions met with in service.

Another object of my invention isthe provision of a hook which is cheap to produce, composed of a minimum number of'parts, and which is efiicient in action.

7 Other objects of my invention and the various advantages and characteristics of the present hook construction will be apparent from a consideration of the following detailed description.

The novelty of my invention will be hereinafter more fully set forth and specifically pointed out' in the claims appended hereto.

As illustrating one form of device embodying my invention, though without limiting myself to the details of construction or arrangement of parts shown and to be herein described, but availingmyself of all changes and modifications which may be made within thescope of the appended claims, I have shown a snap hook comprising a hollow, cast metal body portion 5 which consists of a pair of laterally spaced side walls 5*, a front wall 5 and a rear wall 5, and supports an upstanding, overlying hook portion 6 comprising a pair of depending, inwardly turned,'ring-engaging members 6*. Lugs 7 are formed integrally with and project outwardly from the bottom parts of the side walls of the body portion 5 and have apertures formed therein whereby the body portion may be attached to a firemans rain coat or other garment. A V-shaped leaf spring 8 is mounted withinthe body portion and is arranged so that the end part of one of thelegs thereof rests upon a crossbar 9 and abuts against a'rib 10 on the crossbar 9. The other leg of the spring bears against the inner ends of the ring-engaging members 6 of the hook portions 6 and normally closes the restricted entrance or throat part between said members. The bent central partof the spring fits in a seat 5 which isformed' as an integral part of the rear wall 5 of the body portion and is located adjacent the base of thehook 7 portion 6. The rear end of the body portion 5 embodies a comparatively large bottom opening 5 directly in back of the crossbar 9 to permit the spring to be inserted into place in the body portion during assembly of the hook. In inserting the spring into place the ends of the legs are first compressed and inserted into the opening 5 and then the spring is shifted forwardly in order to bring the bent part into the seat'5 at the base of the hook portion 6. During forward shift of the spring, the lowermost leg snaps into place on the crossbar 9 and in conjunction with the rib 10 locks the spring against displacement. In order to permit of ready removal of the spring,

the body portion 5 is provided with a'bottom opening 5 directly in front of the crossbar 9. By inserting any suitable instrument through this opening into engagement with the extreme outer end of the uppermost leg of the spring and then shifting the instrument rearwardly, the spring, after dislodgment of the bent part from the seat 5, may be removed through the opening 5' A'throat 12 is formed in the side Walls of the body portion 5and forms a passage for the engagement of an ordinary D-shaped ring 13 which is shown in the drawing as being secured by a loop 14 to that portion of the garment which is to be held by the hook. This throat is slightly curved and leads to the restricted entrance between the inwardly extending ring-engagingmembers of the hook portion 6. The uppermost leg of the U-shaped spring 8 is longer than the lowermost leg and extends across the throat so that when the ring is inserted into the throat for shiftinto the hook portion 6 the spring is compressed to free the entrance to the hook portion. The extreme outer end of the upper leg of the spring normally engages an overhanging lip 5 which is formed as an integral part of the front wall of the body portion 5 and coacts with the side walls to form the entrance to the throat 12. This lip limits outward movement of the uppermost leg of the spring. 7 y i The lower edge of the body portion is provided with drainage channels 15 to permit the escape of any water which might accumulate within the body portion 5 during use.

In use, the body portion is riveted a certain distance back from one of the edges of the garment and the ring 13 is applied to the other and overlapping edge. It is to be noted, particularly from Fig. 2, that when the ring is engaged with the hook portion, the outside surface across both ring-.andhookportion is continuous and no hang-- the snap cooperates with the bill of thehook, the

snap and the end of the bill being away from the surface of the garment, there have been a number of instances where firemen have been seriously impeded in their work by wires becoming engaged with the hook which makes it neces- .,'-sary fortthe fireman to release the snap and dis- :engage the wire from the hook before he can proceed and this condition is a great hazard to ..the fireman,.and particularly if the wire happens to be charged with electricity because it is nec-J -;essary for the fireman to grasp the wire with his a hand whilereleasing it from his hook.

In addition, to release the ordinary hook requires the ..use of one hand to release the snap and the other ,one hand, leaving the other hand free.

hand to disengage the ring whereas with my hook, the ring may beeither engaged or disengaged with .To .engage the ring, it is only necessary to enter it into the throat 12 and :forcethe spring 8 downward whenpviewed from the position in Fig. 1 2, untiltheringenters its recess or entrance un- I. derlthe hook portion, and it is to. be noted that.

I 'when the ring is engaged with the hook portion, it lies clear of the spring as the point of the hook 5- portion is'turned back under the 'ring thus relieving the spring of any function ofmaintaining the ringyengaged with the hook portion.

To release the ring it is only necessary to move it downward into contact with the spring and then ;.compress'the spring-by further downward pres- -sure onthe ring and withdraw the ring through xthe throat 12, all of the operation being performed by; a single motion f one hand.

-With the hooks at present in use, in which the hook portionitself is reversed, and in which the @end of the bill stands away from the garment instead of towardit, it is necessary to provide a readily seen, it is only necessary to move the ring better, fitting garments may bermade with my hook than formerly because the amount of slack in the garment, necessary in order to, hook or aunhook the ring with the ordinary hook, is practically all eliminated by the use of my hook.

Itwill be seen from the above that I have produced a hook. of cheap and efficient construction; onepthat, may be easily and quickly operated;

@onethat requires the use of only one hand; and one which, when its ring is engaged with it, is entirely safe from accidental engagement with wires and the dangers incident thereto.

Having thus fully described my invention, I
