SPECIFICATION forming part of Letters Patent No. 353,890, dated December 7, 1886.
Application filed Sepember 20, 1886.
T 0 all whom, it may concern.-
Be it known that 1, CHARLES H. SMITH, of New Haven, in the county of New Haven and State of Connecticut, have invented a new Improvement in Snap-Hooks; and Ido hereby declare the following, when taken in connection with accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in
Figure l, a sectional side view of the hook; Fig. 2, a top View, the tongue removed; Fig. 3, an under side view, the tongue removed; Fig. 4, a longitudinal section showing the side of the recess in the body in which the groove a is formed; Fig. 5, a longitudinal section showing the opposite or stud side of the recess; Fig. 6, a transverse section cutting through the hub; Fig. 7, a top view of the tongue detached; Fig. 8, a recessed side view of the tongue; Fig. 9, an under side view of the tongue; Fig. 10, the stud side view of the tongue; Fig. 11, the spring detached; Fig. 12, a transverse section through the hub, showing the method of introducing the tongue and spring; Figs. 13, 14, and 15, modifications.
This invention relates to an improvement in that class of snap-hooks in which the body is constructed with a hook at one end and with a loop at the opposite end,with a tongue hung in a recess in the body in the plane of the hook, and provided with a spring to force the tongue up and outward against the end of the hook, the object of the invention being to make the spring perform the double function of a spring for the tongue and as the means for holding the tongue upon its pivot.
A represents the body, terminating at one end in a hook, B,and at the opposite end in the usual loop,C. The body is constructed with a longitudinal recess,D,in the plane of the hook, and in this recess the tongue E is arranged, the width of the recess corresponding to the hub F of the tongue, so as to allow free play of the The recess D is constructed upon one side with a groove, at, opening to the under side of the body,and extending upward terminates in semicircular shape concentrically, as seen in Figs. 3 and 4. Upon the opposite side Serial No. .2l3,996. (No model.)
of the recess is an inwardly-projecting stud,b, as seen in Figs. 2 and 4, the stud b and the semicircular end of the groove a being concentric the one with the other.
The hub F of the tongue is constructed with a recess, (1, upon one side to form the spring chamber, and concentrically in this recess is a stud, e, a little smaller in diameter than the internal diameter of the spring to be employed. Upon the other side of the hub is a concentrically-projecting stud, f, corresponding to the groove 0. in the recess of the body, and so that the hub may be set into the recess in the body. The studf passing into the groove a, and arrriving at its concentric seat, the studs d and f will stand concentric and in line with the stud bin the recess, as seen in Fig. 6.
On the recessed side of the hub anotch, h, is out from the recess'outward sufficient to permit the hub to pass the stud b as it enters the recess in the body.
Thespring G (see Fig. 11) is ahelical spring wound open, and of an internal diameter slightly larger than the studs ab, and so that it may be setinto the recess in the tongue around the stud e. At one end of the springit termi nates in an arm, 1', and at the opposite end it terminates in an arm, Z, one arm, Z, adapted to take a bearing upon the tongue, and the other arm, t, to take a bearing upon the body of the hook in the usual manner for this class of springs, and so that the spring acts between the tongue and body as. a torsionspring. The length of the helical spring is somewhat greater than the depth of the recess in the tongue.
The spring is introduced into the recess in the tongue and around the hub e, as seen in Fig. 12, and because of its length it extends outside the plane of the recessed side of the hub.
To introduce the tongue and spring to the bodythe spring is compressed, as indicated in broken lines, Fig. 12, to such an extent that it may pass the stud b, and thus compressed the tongue is passed up through the recess D in the body, the notch h permitting it to pass the stud b, and the compressed condition of ICO until it arrives at the concentric position, then the spring left free expands in the direction of its length and passes onto the stud b, as seen in Fig. 6. Because of thus passing onto the 5 hub, the spring acts as a sleeve over the stud e on the tongue and the stud b on the body, and thus forms a support between the'two to hold them in line,or concentric position. The hub of the tongue cannot be moved in any direction except rotative, because the spring held in the hub embraces the stud b in the recess, and it can only be removed by forcibly compressing the spring, so that it may escape the stud b, and this operation is one of ex treme difficulty, so that whilethe parts are readily assembled there is no liability of their displacement by accident. By this construction the tongue in beingintroduced may pass below the nose ofthe hook without turning the hook to one side; hence the body andliook may be cast in the same plane in which they are to stand without turning to one side, as in the more general construction, and which necessitates the bending of the hookinto its natural plane after the tongue is introduced, and in which operation very many hooks are lost. Again, this method of supporting the tongue avoids casting the recess open and then closing the recess upon the hub after the tongue is introduced in fact, the hook and tongue are cast in their complete shape and form without bending of any character, and all loss due to the bending, as in previous constructions, is avoided.
If it should be desirable to close the notch hin the tongue, it may be done by casting the tonguewith an up wardly-projectingflange, m, adjacent to the notch h, as seen in Fig. 13,and which, after the tongue is introduced, may be bent down to close the recess. So, also, should it be desirable to close the opening in the groove a, a flange, it, may be cast upon the side of the body adjacent to the open end of the groove, as seen in Fig. 6, and turned in 5 ward after the tongue has been introduced;
but neither of these flanges are.necessary, as the exposure through the openings is no objection.
I prefer to construct the tongue with the concentric stud e in the recess; but this may be omitted, as indicated in broken lines, Fig. 6, the spring taking its bearing upon the stud b on its inside, and outside upon the wall of the recess in the hub. I also'prefento construct the body with the groove a, and the tongue with a corresponding stud, f but these may also be omitted, as seen in Fig. 14.
The notch h may be omitted in the tongue, and the recess in the body cast in a spread condition, as indicated in broken lines, Fig. 3, and the body closed after the tongue is introduced, the spring extending onto the stub b, as before described,and so as to form the hearing between the tongue and body.
Theengagement between the spring and the body, whereby the spring substantially forms applications which I have made for Letters the ivot upon which the tongue turns, may 4 be made by constructing the side of the recess in the body with a cavity, instead of the stud b, as seen in Fig. 15, the diameter of the cav- 7o ity corresponding to theexternal diameter of the spring, and so that in introducing the tongue the spring, being compressed to enter the recess D, will,when brought to its concentrio position, expand in an axial direction and enter the cavity, as in Fig. 15. It is therefore only essential to the invention that the body shall be constructed to receive the spring under its expansion in an axial direction.
By taking advantage of the expanding force of the spring in a longitudinal or axial direction to engage the tongue with the body and form a bearing upon which the tongue turns, I avoid much of the mechanical labor necessary in previous constructions in securing the tongue in place. and oonsequentlyreduce the cost of manufacture.
Certain features of the hook described in this application are also shown in two other Patent, Serial Nos, respectively, 213,995; and 215,217, and I do not wish to be understood as claiming anything in this application which I have claimed in either of the said two applications.
I claim- 1.
