JAMES P. BAILEY, OF ALLEGHENY, PENNSYLVANIA, ASSIGNOR TO BAILEY 85 ANGLIN, OF SAME PLACE.

SPECIFICATION forming part of Letters Patent No. 242,247, dated May 31, 1881. Application filed March 14, 1881. (No model.)

To all whom it may concern:

Be itknown that], JAMES P. BAILEY, of the city and county of Allegheny, and State of Pennsylvania, have invented an Improvement in Locks, of which the following is a specification.

The object of my invention is an attachment for looks, whereby the friction and jar resulting from the striking of the beveled face of the latch against the keeper is prevented, the device being constructed, as fully described hereinafter, so as to be effective with the latch in either position, and therefore applicable to reversible latch-locks.

In the drawings, Figure l is a perspective view of a lock with a portion of the face-plate broken away to illustrate my improvement. Fig. 2 is a sectional plan, and Fig. 3 is a detached view, showing the anti-friction tumbler.

The lock-case and its latch A, together with the devices for permitting the said latch to be reversed, are constructed in any suitable manner, either specially to embody my improvements or in any of the well-known forms. From the opposite sides of the latch extend pins or lugs a, and upon opposite edges of the face-plate, on the inner side thereof, project ears b, the said ears being arranged above or below the head of the latch, as may be found most convenient. To either of these ears may be pivoted a detachable segmental tumbler, B, having a central notch, 0, adapted to receive the lugs a of the latch. This tumbler B is of such a shape that when the latch is thrown forward it will present an inclined edge, 00, extending beyond the beveled face of the latch, as shown in dotted lines, Fig. 2. On closing the door the edge 00 will strike the keeper and the segment will be turned in the direction of the arrow, and while acting as a lever will force 4 back the latch more readily and with less friction than if the beveled edge ot'the latch struck the keeper.

When the latch is reversed it is only necessary to pivot the segment to the opposite ear 4 I), and the operation will be the same as before.

I thus, by the use ofa single detachablepiece, secure the same results with a reversible latch as have heretofore been obtained by the employment of more complicated devices. 5c

Different modes of pivoting the segment may be employed. For instance, the segment may have lugs 8 adapted to holes in the ears, or the lugs may be upon the ears and the hole in the segment. In like manner the lug a may be upon the segmentand corresponding slots may be made in the latch.

If desirable, the lugs 1) maybe upon the sides of the lock-case.

Without therefore limiting myself to the precise arrangement shown, I claim- The combination, in a lock provided with devices for permitting thelatch to be reversed, of a latch, A, lugs b, and a segment, B, adapted to be pivoted to eitherof said lugs, to have a bearing upon either side of said latch, and constructed for operation substantially as set forth.

In testimony whereofI have signed my name to this specification in the presence of two sub- 7T0 scribing witnesses.

JAMES P. BAILEY.
