Be it known that we, ELLERY I. ANDERSON ,and OSCAR M. MORRILL, citizens of the United States, residing at Charleston in the county of Charleston and State of South Carolina, have invented new and useful Improvements in This invention; resides in the novel features Aof construction ,set forth in the following fiann'exed drawings, in which-'- Y Figure lisa sectional plan viewr of the lock.4 Fig'. 2 is asection along fw w, Fig. 1..

' lining.

The doori is adapted to be held Shut-orto y the jamb 2 by bolt3,havinga hollow or tubular tailpieeeei, and normally held or moved to locking position'by spring 5. The door-is Qmortised to receive a lining or tube 6, in which the bolt can play." 'A slot-and-pin connection 7 and 8 can be'made to suitably limit the play of theLbolt.

The tailpiece 4 and vlining 6, as seen inFig. 7, have cuts or passages 9 andv 10 for a purpose presently explained, and said tailpiece 4 alsohas a cross-piece 11,i-n form of a rod, extended across the chamber or interior of this hollow tailpiece.

The door at its inn'er side is shown with escutcheo'n'12'and at its outer side with es- .cutcheon-13, suitably fastened or screwed in placein 'anyisuitable manner. Through the door extends atiibe or'housing14, shown with theouter .knob fixed or castthere'to. The

. inner or removable knbblcan be secured in suitable way, asfby shoulder'l' and screw 18,

holdiiigrthe knob fixed on tube 14.` In the tube l14 lis a spindlelQ.` This spindle is also shown in tubular` form and carries a "lug 20. The spindle is longitudinally movable in tube 14, and when shifted tocarry or slide`lug'20l ;through the passages 9 and 10, Fig. 7, so that thelug restsv in the hollow tail 4, Fig. 4, the spindle when rotated to carry lug against l cross-piece 11 will withdraw or open the 'bolt X,4

' ently of said spindle, a suitable slot-and-pin connection and 31,' Fig. 6, being made to connect the parts`29 and 19. ThespindlelQ is longitudinally movable in tube 14; but said tube andspindle rotate together. ig "j i' The spindle is Ashownwi-tha scrfiworfasloo'p 34 is vsecured tothe spindle.

be moved longitudinally, or, in other words, the handle at the inside replaces the key 22 and trigger 3l, which come into use at the outside. The spring 37, Fig. 1, is applied to normally rotate stem 2O t0 position for the catch 25 to engage lip 2S when the stem 1H slides outward. 'lhe spring 3S tends to move the spindle 19 inward or into active position. The tube 14; is of course suitably slotted to allow the lug 20 to move back and forth with the spindle 12). The tube M, while rotary, has The lip 2S is fixed or cast in the tube 1l.

lVhat we claim as new, and desire to secure by Letters Patent, is

l. The combination with a bolt having a iransversely-arranged passage, of a longitudinallyanovable spring-pressed spindle having a lateral rigidly-attaehed lug forentering said passage to actuate the bolt, a device for holding the spindle with its lug outof engagement with the bolt, and means for releasing said holding device to permit the spring acting on the spindle to aetuate the latter and move the lug into engagement with ihebell, substantially as described.

2. The combination with a bolt having a transverse] y-arran ged passa ge, of a knob-earrying tube, a tubular spindle arranged in the knob-carrying tube, rotating therewith and movable longitudinally independent thereof, a lug rigidly secured to and projecting laterally from the tubular spindle to enter the said passage of the bolt, a spring for moving the spindle in one direction, a device for holding the spindle against the tension of the spring, and lneans foroperating said device to release the spindle and permit its spring to operate and cause the lug to enter the said passage, substantially as described.

3. A tube orhousing having a lip, a spindle having a catch for engaging the lip, a lug on the spindle, and a bolt, said spindle being made longitudinally movable to carry the lug into and out of engagementwith the bolt and said catch being made rotatable to eleai' or move to one side of the lip substantially as deseribed.

4. A tube or housing having'a lip, a longitudinally-movable spindle having a catch for engaging the lip, a lug on the spindle, a bolt adapted to be engaged by the lug, a rotary stem in the spindle and t0 which the catch is connected, and a button or handle at one end` of the spindle for rotating said stem, the other end of the spindle being adapted for the insertion of a key substantially as described.

5. A tube or housing having a lip, a longitudinally-movable spindle having a catch for engaging the lip, a lug on the spindle, a bolt adapted to be engaged by the lug, a rotary stein in the spindle for supporting the catch, a button or handle for the stein, and a keybloeli forked for the respective engagement of the catch and of a keysubstantially as described.

(i. A tube or housinghaving alip, a spindle having a catch for engaging the lip, a lng on the spindle, anda. bolt adapted to be engaged by the lug, said tube being slotted and said spindle having a handle or trigger extended through the slet substantially as described.

7. A door having a nlortise, a bolt in the mortise, a spindle7 and a lug on the spindle adapted to engage the bolt7 said door having a slot or seat for the lng and said spindle being longitudinally movable to carry the lug from the slet to the bolt substantially as described.

In testimony whereof we have hereunto set our handsin the presence ol two subscribing witnesses.
