THOMAS FORSTNER, OF
NEW ULM, MINNESOTA.
SNAP-HOOK.
Application led. November 25, 1905, Serial No. 289,1
Specication of To all whom it may coacem:
Be it known that 1, THOMAS FoRsTNnR, a citizen of the United States, residing at New Ulm, in the county of Brown and State of Minnesota, have invented new and useful Improvements in Snap-Hooks, ot which the following is a specicat-ion.
This invention relates to that class ot snap hooks in which a pair ot' spring actuated twin hooks are pivotally combined with a clevis or supporting member in such a manner that by pressure of the fingers ot the operator upon the heads of the hooks, said hooks may be separated or spread apart for the introduction between them of the part or member that is to be supported by or connected with the snap hook.
The object of the invention is to simplify and improve the construction and operation of this class ot devices; and with these and other ends in vie-w which will readily appear as the nature o1" the invention is better understood, the same consists in the improved construction and novel arrangement and combination ot parts which will be hereinafter fully described and particularly pointed out in the claim.
ln the accompanying drawing has been illust-rated a simple and preferred term of the invention; it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modiiications within the scope of the claim may be resorted to when desired.
In the drawing, Figure 1 is a side elevation ot a snap hook constructed in accordance with the invention. Fig. 2 is an edge view of the same. Fig. 3 is a sectional elevation taken on the plane indicated by the line s a in rig. i.
Corresponding parts in the several figures are denoted by like characters of reference.
The c levis or body portion 1 of the device includes the cheeks or side members 2 2 which are spaced apart as clearly seen in Figs. 2 and 3, and are connected with each. other by means of a transverse pin or bolt 3.
The twin hooks of the device each include a shank portion 4, a reversely turned hook member or nib 5 and a head G. Said hooks are of identical construction; and the heads 6, which are of substantially circular shape, are provided with milled or serrated edges 7 affording a convenient grip for the tingers of the operator. The hooks, which are Letters Patent.

Serial No. 474,496.
pivotally mounted upon the pin 3, which latter extends through the heads (3, are provided in their opposing faces with chambers or cavities S, for the accommodation ot a spring 9 which is coiled upon the pin 3, and the terminal ends ot' which, 10, are seated in recesses oi' the chambers or cavities S, as will be clearly seen in Fig. 3; the tension ot' the spring heilig exerted to maintain the hooks normally in a closed position, as shown in Fig. l; one of the hooks being provided with a stop lug or abutment 'll .vherebyY the movement ot the hooks in the direction ot each other, under the tension ot' the spring, is limited. By pressure ot the thumb and tinger of the operator upon the milled or serrated edges ot the heads or" the hooks, the latter may be spread apart against the tension or' the spring for the introduction therebetween ot' a link or other member with which the snap hook is to be connected; when `pressure upon the edges ot the heads is relaxed, the twin hooks will immediately be restored, by the action ot the spring, to a closed position. rhe arrows in Fig. 1 indicate the direction of the movement of the twin hooks under the pressure ot' the fingers ot the operator.
From the foregoing description it will be seen that the improved snap hook is extremely simple in construction, as well as ell'ective in operation. lt may be manufactured at a very moderate exp-ense, and it is thoroughly useful and eilicient Jfor all purposes to which snap hooks are ordinarily applied.
Having thus t'ully described the invention, what is claimed as new is A snap hook comprising a clevis having` spaced jaws or side members, a pin connecting said side members, twin hooks pivoted upon the pin and having heads provided with milled edges, said heads being provided in their opposed faces with cavities and recesses, and a spring coiled upon the pin wit-hin the cavities and having terminal ends seated in the recesses; one ot said hooks being provided with a stop lug forming an abutment.
.In testimony whereof, l ax my signature in presence of two witnesses.
