COMBINED BUCKLE AND SNAP-HOOK;

. adapted for use upon harness and for connecting the driving-reins with the bit or the tugs to the hames. It is furthermore designed to provide a comparatively flat device having no projections to catch in the harness; also, to provide means for detachable application to a strap, so that the latter may rest fiat upon the device, and finally to arrange the tongue of the hook in such relation to the means for connecting it to a strap that the operation of view of a snap-hook constructed in accordance Fig. 2 is a lon- Fig. 3 is a' with the present invention; gitudinal sectional View thereof. top plan view of the snap-hook.
Corresponding parts in the several figures of the drawings are designated by like characters of reference.
Referring to the accompanying drawings, it will be seen that the body of the snap-hook comprises a substantially-flat plate 1, having the opposite longitudinal flanges 2 extending the entire length of the plate and forming a substantially-rectangular box for the reception of a strap 3.
To look the strap to the snap-hook, I have provided a tongue in the form of a fiat plate 4, which fits easily between the flanges 2 and has its outer end pivoted to the outer or rear ends of the flanges and near the upper edges thereof, as indicated at 5, and also provided upon its inner face with a lug or spur 6, which is designed to pass through the perforation 7,
commonly formed in straps, and also to enter an opening 8, formed in the plate 1. By reference to Fig. 2 it will be seen that in the'locked position of the pivoted plate4 the latter rests upon the top of the strap and is also flush with the outer edges of the flanges 2, whereby the rear portion of the snap-hook is entirely free from projections. Furthermore, the pull upon the strap 3 comes upon the lug or spur 6, and as the latter projects from the inner face of the plate 4 such pull or strain tends to bind the plate more firmly uponthe strap,
and asthe spur enters the opening in the plate 1 it is effectually braced thereby, so as to relieve the strain from the pivotalor hinged connection of the strap-engaging plate or tongue 4.
The fortwtrdportion 9 of the plate 1 is iny clined laterally and forwardly upon the pivoted-plate side of the snap-hook, and the forward portions 10 of the flanges 2 converge foruwardly into the inclined portion of the plate .and are then formed into a hook or bill 11, the extremity of which is located upon one inner ends of the convergent portion thereof. As illustrated in Fig. 2, it will be seen that the tongue is inthe form of a substantially right-angle triangle and projects through a slot 14, formed longitudinally of the inclined portion 9 of the body of the snap-hook, so as to substantially close the entrance-opening into the bill 11. The tongue is normally held in its closed position by means of a leaf-spring 15, having one end engaging the inner side of the plate 1 and its opposite end fitted into a notch 16, formed in the under side of the tongue and in advance of the pivotal axis thereof, so as to normally bear down ward and maintain the tongue in its closed position. By reference to Fig. 3 it will be seenthat the upper or outer portion of the tongue "substantially fills the space between the convergent portions of the flanges 2, and the comparatively-broad rear portion 17, forming an op- *have a bearing in the flanges 2 and near the ICO erating thumb-piece, is located in advance of and adjacent to the inner free end of the pivoted or hinged plate 4, so that when the th umbpiece is depressed the thumb or finger of the operator is directly over and also bears against the free end of the plate 4 and efiectually oted bet-ween the flanges, cooperating with prevents the latter from being accidentally disengaged from the strap during the operation of the thumb-piece. It will also be noted that the outer face of the tongue is substantially flush with the convergent portions of the flanges 2, and therefore does not project sufiiciently to he accidentally operated by engagement with any portion of the harness. The shape of the spring 15 is immaterial, as
it may be straight instead of bowed; but it should be connected at its forward end to the tongue 12 only, while its rear end is freely slidable upon the plate 1 and is designed to ride forwardly upon the forwardly-inclined end 9 of the plate 1 when the thumb-piece 17 is pressed, thereby exerting an inward tension upon the forward end of the tongue to close the latter after the thumb-piece has been released.
\Vhat I claim is- V 1. In a snap-hook, a body, having a bill at one end and disposed upon one'side thereof, a spring-actuated tongue, cooperating with the bill, and disposed longitudinally of the body, and a strap-engaging tongue pivoted to the opposite end and upon the opposite side of the body, alined longitudinally with the spring-actuated tongue, and having its free end located adjacent to the latter tongue.
2. In a snap-hook, asubstantially-fiat body, having opposite longitudinal flanges extending the entire length thereof, a bill located at one end of the body, and a flat plate pivoted to the opposite end of the body and located between the flanges, and provided upon its inner side with a strap-engaging lug or spur, and a spring-actuated tongue also pivthe bill, and having an operating th u m b-piece arranged in advance of and adjacent to the free end of the pivoted plate.
3. In a snap-hook, a substantially-fiat plate, having one end inclined laterally and forwardly, and provided with a longitudinal slot, a bill provided at the forward extremity of the inclined end, longitudinal flanges located at opposite edges of the plate, extending the entire length thereof, andhaving their front portions converged into the bill, a tongue mounted between the convergent portions of the flanges, projecting through the slot in the plate, to cooperate with the bill, and provided with an operating thumb-piece, and a flat plate located between and pivoted to the outer ends of the flanges and near the upper sides thereof, foldable inward between the flanges, and having a lug or spur provided upon its inner face, the free end of the pivotal plate being located adjacent to the operating thumbpiece of the tongue.
In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
