Letters Patent No. 109,849, dated December 6, 1870.

IMPROVEMENT iN BUCKLES.

The Schedule referred to in these Letters Patent and making part of the same.

To all persons to whom these presents may come:

Be it known that I, GEORGE E. STEDMAN, -of

- Boston, of the county of Suffolk and State of Massiv chusetts, have invented a new and useful orlm- Aproved Buckle; and do hereby declare the same to be fully described in the following specification, and represented in the accompanying drawing, in which- Figure l is a top view; Figure 2, a, horizontal section; and

Figure 3 is a longitudinal section of'it as applied to a strap. A

' In this buckle the tongue .is provided with a lockto move with the tongue, and to serve lto fasten the tongue down in the frame to which such tongue may be. pivoted.

In the drawing- A denotes. the buckle-frame, which has within it and pivoted to it, as shdw'n at a a, the box b of a lock, B, from which the buckle-tongue C projects, and when down in the frame enters a small rccess,^d, inA the frame..

The box B contains two bolts, c c, connected by a joint-link or lever, f, having its fulcrum at q.

To .one` of the said bolts there is a se't'of ono or more tumblers, 7e, to Operate with a stud, i.

'lhe bolts play through opposite sides of the lock- V case', there being recessed] l, made in'tho frame of sense constitutes part of the tongue, the two being movable together withirithe buckile-frame.

On turning the key the boltsvwillbe simultaneously Yshot forward or retracted, as occasion may require,

whether to fastenthe tongue or unfasten it` as circum- 2 stances may require.

The strap'is to be fastened to the end bar m of the f frame. I am aware of the tug-buckle shown in the United States Patent, No. 47,570, such tug-buckle beingrepresented as having a tongue stationary relativeto the .buekle-frarne, and having to thelatter a pivoted plate or cap provided with a latch, the object of such plate being to hold -the strap in place on the tongue. I make no claim tp such tug-buckle.'

Nor do I herein claim a buckle as provided not only with a tongue pivoted to the frame, but with a capplate pivoted to such frame and furnished with a lock to fasten itdow'n in the frame, such being as shown in a pending application for a patent filed by me on March 31, 1869.

My present locking-buckle is much simpler' in con'- struction than the latter', and is better in many respects. Y

Although I have shown the lock as provided with two boltsv to operate in opposite'directions from it, a lock having a single bolt maybe substituted; but one with two bolt-s is preferable on account of the better support they afford thelock iu the frame.

I make no claim to a'lockingfbu'ckleconstructed in either of the ways" as described in the English patent of Greenwood, dated December 14, 1869, wherein the lock is made fast within or to the frame as to be immovable with respectto it.

In iny buckle, however, the lock is hinged to the frame, and the tongue projects directly from the lockcase, and is movable with it relatively to the frame, such changes in the buckle admitting of' a strap being introduced aiuldrawn into or out of the frame with f great-er:l facility.

. I. therefore claim as my invention- The im proved locking-buckle, having its lock-case piroted tothe frame and the tongue projected from the said case and movable withit, as described.

' GEO. E. STEDMAN.
