LOCK.

SPEGIFICA'IION forming part of Letters Patent No. 631 ,431g dated Augustl'22, 1899.

Application filed April 2 8, 1.89 9.

To all whom/fit may concern:

Be it known that I, BYRON PHELPS, a citizen of the United States, residing at Seattle, county of King, State of Washington, have invented certain new and useful Improvements in Locks, of which the following is a full, clear, and exact description. n My invention relates to improvements in locks and locking latch mechanism; and my object is toimprove and simplify the construction of the same.

In the preferred embodimentzof myinvention shown in the drawings, Figure l represeuts a plan view of my lock,1parts being broken away. Fig. 2 represents a horizontal section. Figs. 3 and 4 represent enlarged def. tails. Fig. 5 represents the position of the parts when the right-hand spindle is locked but the other is not. Fig. 6 represents the position of the parts when both spindles are locked. Fig. 7 represents a detached detail showing the manner of lockingthe latch-shoe, and consequently both spindles, by one of the roll-backs. Fig. 8 is a detail of t-he rollbacks.

In the above preferred embodiment of my invention A represents the frame of a lock, preferably havingintegral, hollow,transverse spindle-.bearings B and C. b and c are side or escutcheon plates fitting over these spindlefbearings and relativelyv adj ustable. This lock is adapted to be inserted in a notch in the stile of a door, and the side 'plates are toI clasp the sides of the stile and retain the lock in place. This general construction is broadly claimed in my former application, renewed December 5, 1898, Serial No. 698,371. D and E are in this embodiment two independent and hollow rotatable spindles, held in the spindle-bearings preferably by a pinfandgroove construction, as shown in Figs. 1 and 2. The spindle D has a slot d, Figs. 5 and 6, and spindle E a slot e, Fig. 7, through both sides of the same at the inner end thereof.

Held loosely within the end of the spindle E is a roll-back G, having the wings thereof located in the slot e, as shown in Fig. 8. The roll-backpreferably is just large enough to snugly fit within the spindle, so that it can be easily moved therein and in said slot.

F is a second rollaback held within the end Serial No. 714,831. (No model.)

of the spindle D and having its wings located ini the slots d in the spindle in the same manner as in Fig. 7.

The central part of the 'roll-back G is prefa erably a little larger than the opening in the end of the spindle D, (see Fig. 2,) so that there will be no danger of said roll-back passing into the spindle D, and thereby becoming disconnected with spindle E.

' H is a latch bolt or head, and 71, is a latchshoe provided with a yoke, the legs h and h2 of which embrace both spindles, as clearly shown in Figs. 1 and 7. Each of the legs of the shoe has a lip hwhich lips lie behind the wings of the roll-back when in their proper position and are kept in engagement therewith by the spring h4,which presses the shoe and latch forward. It will be obvious that when in the position shown in Fig. l the latch may be drawn back by a rotation of either spindle in either direction.

b' is a slot in each side of the frame, into which the wings of the roll-back F fit when this roll-back is moved in the slots d of the spindle into the position shown in Fig. 5. c

When in this position, the spindle D is prevented from operating the latch mechanism, but the spindle E can still be rotated to throw back the latch. To prevent either spindle from operating the latch mechanism, I preferably lock both spindles from rotation by bringing the shoe and roll-back G into engagement, in this embodiment the roll-back being. moved to the left into the position shown inl Fig. 6, when the wings thereof enter the recesses h5 h5 in the shoe, as shown in Fig. 7, thereby locking the shoe, and consequently both spindles, from rotation in either direction. To accomplish these different locking movements, I have provided a locking mechanism which extends outside of the lock on the same side as one of the spindles, and in this embodiment I have shown it as partly inclosed Within the spindle E.

K is a lock-rod, preferably angular, but having a smaller rounded portion k. The roll-back F has an angular opening f, Fig. 8, therethrough, so that the angular portion of the rod will just fit therein. The roll-back G, on the contrary, has an aperture large enough so that it can rotate independently ofl IOO the rod. The roll-back F is inserted on the rod to the position shown in Fig. 2, and the rod is then given a slight turn, which will bring it into the position shown in dotted lines in Fig. 8, the corners of the rod abutting gainst the sides of the roll-back, so that by ne longitudinal movementof the rod in either lirection the roll-back will be carried along .vith it. The rod will, however, move freely in a longitudinal direction without moving roll-back G. L is a sleeve longitudinally fmovable inside of spindle E and is pressed forward by the spring l inside of the left-hand knob. A pin Z is inserted in the hole l2, Fig. 3, and passes through a slot Z3 (shown in dotted lines, Figs. 5 and 6) and projects therefrom into a cam-slot in a finger-piece M, rotatable outside of the spindle E. 7a', Fig. 3, is a pin on the lock-rod K, passing through a transverse slot in the sleeve D. By the rotation of the linger-piece the sleeve L, and consequently the lock-rod K, will be moved longitudinally in one direction or the other and will carry the roll-back F along with it. It will be observed from Fig. 5 that the cam-slot in the finger-piece has a greater throw in one direction than in the other. Consequently when the finger-piece is rotated from the position shown in Fig. l to that shown in Fig. 5 the roll-back F will be carried into the position in which only spindle D is locked, and when further rotated into the position shownin Fig. G the said roll-back will be carried to the left, not only as far as the former position shown in Fig. 1, but farther to the left, pushing the roll-back G ahead of it into the recesses in the shoe, as shown in Fig. 6, thus looking both spindles. XVhen the linger-piece is then moved in the opposite direction to the position shown in Fig. 1, the roll-back G might not move out of the recess. I have therefore provided an inner 'spring-pressed means to keep the same normally out of engagement with the shoe, consisting in this embodiment of an inner spring-pressed thimble N. This thiinble has a slot n, into which a pin ZA1 on the sleeve L projects to prevent disengagement of the parts. By the rotation of the finger-piece in one direction the opposite spindle alone is locked, and by a further movement of the linger-piece in the same direction both spindles are locked, preventing the retraction of the latch-bolt, and consequently preventing the door being opened either by a key or otherwise.

Some of the above features are broadly claimed in my former applications, renewed December 5, 1898, Serial No. 698,371, and Serial No. 699,891, tiled December 21, 1898.

It will be obvious that many changes may be made in the construction herein disclosed without departing from the spirit of my invention.

What I claim is- 1. In a lock in combination, latch mechanism, a spindle extending thereto to operate the same, a second spindle on the opposite side of said lock, and means operative from the same side ot said lock as said lirst spindle and adapted to prevent said second spindle from operating said latch mechanism, but not said first spindle, or to prevent either spindle operating the same.
