MATTHEW \V. LYN OH, OF MADISON, WVISCONSIN.
LOCK-BUCKLE.
SPECIFICATION forming part of Letters Patent No. 695,404, dated March 11, 1902. Application filed May 9, 1900. Serial No. 16,082. (No model.)
To all whom it may concern.-
Be it known thatl, MATTHEW W. LYNCH, a citizen of the UnitedStates, residing at Madison, in the county of Dane and State of Wisconsin, have invented a new and useful Improvement in Lock-Buckles, of which the following is a specification.
My invention relates to improvements in lock-buckles in which the frame' of the buckle has a mortise to receive and carry a bolt or slide which is operated by a key and provided with a ledge to cover and retain the tongue and a vertical groove or notch to receive a pin for holding the bolt in the desired position in the frame; and the objects of my improvements are, first, to relieve the buckle-tongue from all end thrust when a lateral strain is put upon it, and, second, to provide a means for taking up the wear on the bolt and holding it in position when unlocked. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure l is a vertical section through lines A B on the frame a and O D on the bolt 1). Fig. 2 is a plan, partly in section, showing the positions of the belt I), tongue 0, and re taining or lock pin fwhen the buckle is unlocked. Fig. 3 is a rear edge view of the bolt 17, showing the wing g for taking up the wear on the same. Fig. 4 is a bottom view of the bolt 1), showing the cover or ledge e and the same cut away at cl, also the take-up wing g, formed by milling a slot from the notch it through to the key-channel 2T.
Similar letters refer to similar parts throughout the several views.
The frame a of my buckle is a rectangular plate upon both ends of which are formed loops, the one with the straight bar to be fasnear the front end is a mortise, and from the center of the "mortise, extending nearly to the back of the frame, is a round hole. the mortise is fitted a flat bolt 1), hereinafter more fully described, and into the round hole is placed a plug or lock pinf, which is forced outward by a spiral spring. (See Fig. 1.) The fiat bolt 1) is formed by cutting out of its front side the groove d, Figs. 2 and 4, and milling away a portion of its rear lower corner, leaving the ledge e, Figs. 1 and 4. Then a key-channel t is out from end to end on the front side, Figs. 1 and 3, and the notch his formed by removing the central portion of the two sides of the channel. On the bottom of the said bolt 1) a longitudinal slot is cut from'the notchh toward the end and intersecting the key-channel t', forming the wing g, which is bent outward, and being elastic will take up any-wear between the mortise and bolt and hold the bolt in position when unlocked. It is clear that the tongue 0, being square across its-end, and" the ledge e, projecting over it horizontally, prevent any end thrust from a lateralstrain on the tongue when the buckle is locked, and thus prevent accidental unlocking of the buckle, and it is also plain that by bendingoutward the wing g on the bolt 19 any play between the bolt and mortise could be taken up. v
To unlock my buckle, a thin metal key is inserted into the key-channel, and the lockpin f is forced back into the frame, and the bolt 1) is pushed through the mortise until the ledge 6 passes from over the tongue'c, as
shown in Fig. 2. To look, remove the key and push the bolt 1) into the frame until the two are flush, when lock-pin f will drop into notch h.
I am aware that lock-buckles similar to this one described have been known and used before, with the exception of the arrangement for preventing end thrust and taking up the wear on the bolt.
I therefore only claim as new the following:
1. The combination in a lock-buckle, of a flat bolt having horizontal projecting ledge c and oppositely-disposed outwardly-projecting elastic wing g and notch h, a lock-pin adapted to engage said notch,'and a buckletongue 0 adapted to be engaged by said ledge Into when the parts are in their locked position, as set forth.
2. The combination, in a lock-buckle, ofa
flat bolt having projecting ledge 6 extending 5 horizontally, and a key-channel 11 upon the opposite edge extending from end to end and a notch h formed in said channel, and an elastic wing g, alock-pin adapted to engage in said notch, and a buckle-tongue 0 over which said ledge rides when the bolt is moved into Id its locked position,substantia11y as described.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
