PATENT OE mEa GEORGE H. NEARING, OF NEW BRITAIN, CONNECTICUT, ASSIGNOR TO THE NORTH & JUDD MANUFACTURING COMPANY, OF NEW BRITAIN, CON- NECTICUT, A CORPORATION OF CONNECTICUT.

SNAP-HOOK.

SPECIFICATION forming part of Letters Patent No. 768,817, dated. August 30, 1904,

Application filed January 27, 1904. Serial No. 190,777. (No model.)

The object of the invention is to construct a snap-hook in asimple and inexpensive manner, which may nevertheless be very strong and readily operable.

The invention consists of three partsa body portion, a tongue portion, and a spring for holding the tongue and body in their proper operable relationsall constructed and assembled substantially as shown.

In the preferred form of my invention a plate having a slot is provided by which the snap-hook may be readily attached to a strap or like structure; but the hook obviously may be attached in other ways.

The invention has particular advantage with that class of fasteners used in connection with harnesses, blankets, hitch-lines, Saddlery, &c. It may also be used for book-straps and with proper modifications for suspender-cast-ofis and other structures requiring a snap-hook fastener.

The details of construction will be seen on an inspection of the accompanying single sheet of drawings, in which- Figure l is a perspective view illustrating the preferred form of my invention. Fig. 2 is a side elevation of the parts of the snaphook at one stage of the process of assembling. Fig. 3 is a detail plan view of the tongue member.

tion riveted to some rigid support and' showing the operation of releasing the hook.

1 indicates the body portion of the hook. 2 is a recess therein. 3 is a spring situated in said recess.

4: is a tongue having a pivot 5. The pivot of this tongue has bearings at the rear of the body portion and is held in place by the shoulder 6. This shoulder 6 is bent down in place in the process of assembling the parts, as will be clearly understood from an inspection of Fig. 2. The spring is inserted in a recess of the body portion with its ends toward the pivot-recess, the tongue slipped under the bill of the hook with the pivot in front of the shoulder. The pivot is then pressed downward and the shoulder 6 bent over to hold the parts in place, where they are securely locked against accidental displacement.

7 is a plate which extends from the pivotal portion of the tongue member and by means of which the snap-hook is attached to whatever is desired. The tongue is arched at 8, and thus provides a convenient position for operating the tongue by means of the finger and also provides a clearance on the under side for the spring. This will be seen particularly on inspection of Fig. 4.

My particular object in combining the tongue and loop members is to make it convenient to open the snap-hook without pressing down upon the tongue with the finger. This method of openingit is shown also clearly in Fig. 4:, where the tongue-plate 7 is held stationaryby the part to which it is attached, while the eye 9 as it engages the bill of the hook pulls the bill outward, so that the eye may then be slipped off upward.

The body portion of the tongue and loop are preferably made of malleable iron, while the lspring is preferably made of tempered stee It will be obvious to one skilled in the art that many changes in the details of construction might be made without departing from the spirit or scope of my invention.
