To all whom t may concern,.- and extending from said rock-lever at right Be it known that I, EDWARD F.

The slide k is proof Lockport, in the county of Will and State vided with a slot k', through which passes a 55 5 of Illinois, have invented certain new and cylindric post or stud Z, projecting from the useful Improvements in Locks; and I do deinside of the face-plate of the case A, and clare the following to be a full, clear, and eX-V upon its lower or inner edge near one end act description of the invention, such as will said slide is provided with an extension m, enable others skilled in the art to which it having a V-shaped notch m', having a rect' 6o 1o appertains `to make and use the same, referangular termination at its vertex.

5o ing a recess t' in the bolt B, and passing The manner of application of this lock to through the slot e of the barrel or bearing b, one form of door to which it may be applied is shown in Fig. 3, the stiles Xiand Y of the overlapping doors being` shown in dotted lines. The stile or doorYis shown as carrying the lock, while the stile or door X receives the bolt. It is evident that this lock is adapted to all forms of sliding overlapping doors or to doors which overlap a jainb.

In the modification as disclosed in Fig. 9 the lock is shown as adapted for use in connection with warehouse, barn, and stable doors. In this modification the face-plate is shown as having a shoulder G to receive the abutting edge of the opposite or other door. In this modification the rock-shaft is also shown as located between the tumblers` and the bolt, instead of as shown in the other iigures and as heretofore described. The operation, however, is substantially the same.

Having described this invention, what. I claim as new, and desire to secure by Letters Patent, is-

l. The lock having the laterally-movable bolt, in combination with the rock-lever hav-y ing an arm engaging said bolt, and the actuating mechanism comprising a slide acting z t Nitnessesr upon a second armr of said lever, substantially as set forth. 2. The combination, with the bolt and its inclosing barrel or bearing, of the yrock-lever havingan arm engaging said bolt, the slide engaging a second arm of said lever and having a slot receiving a post or stud of the faceplate of the case and a second slot, and the tumblers, one having a T-shaped slot and the others each having two slots connected `by a kcontracted slot, all of said slots being engaged by a lug on said slide, and means for actuating said tumblers and slide, substantially as set forth.

3. In a lock, the combination of the case having its face-plate provided upon the inside with the slotted barrel or bearing, the bolt having a tiange at its inner end formed with a guide extension or projection engaging the slot of said barrel, the spring placed around said bolt and interposed between said flange and a seat at the outer end of said barrel, and means for actuating said bolt, substantially as speciiied.

In testimony whereof I affix my signature in presence of two witnesses.

ED WVARD F. BARROXVS.
