Figs. with the outside thereof, as indicated in Fig. S and 9 show another night-lock of varied la, is slotted or otherwise formed, as at t, to eonstruction,showing the locking and unlcckreceive a dead-latch, lock, or fastener u, Fig. 10o 5o ing positions and Fig. 10 is a sectional View 4, which is fastened to the `interior side of the taken on line x, Fig. 2. Fig. 11 is a front door on a suitableinside plate in line with the said slotted hub, the said latch or fastener entering into the slot tto lock the tumbler or prevent pivotal movement of the hub. The said dead-latch, lock, or fastener is provided, where it projects from the door, with a fingerpiece which operates the latch or fastener, so as to prevent pivotal action of the tumbler p. The preferred dead -latch or fastener is shown in Fig. 4, in which n is abearing-plate, which may be a part of the escutcheon-plate, either integral or an independent piece soldered or otherwise attached to said plate and providing bearings adapted to allow a pivotal movement of the nger-piecef. At the rear of said bearing-plate are ways 3, between which the dead-latch slides to and from the slot t in the tumbler p.
The dead-latch u, is provided with a screwshank 4, which enters the threaded fingerpiecef, so that the pivotal action of said iinger-piece produces the desired movementof the latch to and from the slot in the tumbler p to fasten or release the said tumbler.
The latch-bolt 71; may be locked by other means than those above described. For eX- ample, I may employ a dead-latch, such as shown in Figs. 8, 9, and 10, in which the linger-piecefis provided with a shank f', havinga pin f2, working in an inclined groovef3 in a sleeve f4, adapted to be inserted in the door ct and to hold the shank f. The sleeve and its shank are so disposed as to engage the bearing 5 of the latch-bolt lo, when the said shank is forced inward by turning the pin f2 on the incline of the groovef, as will be understood. At the side of the tumbler Zon the section e of the spindle connecting with the outside door-knob d is arranged analarmtumbler 6, having arms 7 7, which engage a jointed lever S, fulcrumed at 9 to the case y2.-
Variations may be made in the relations of the tumbler-arms 7 7 to the lever 8, as may be noted by comparing Fig. l with Fig. 3; but the preferred construction is indicated in Fig. 1, where the lever is provided with a V- shaped notch or recess 10, Fig. 6, in which one of the tumbler-arms 7 works in either direction with about the same ease. The other tumbler-arm 7 is disposed between stops l1 11, which limit the movements of said tumbler, so that the first said arm 7 cannot pass out from the recess l0 when the tumbleris turned. A spring 12 serves to hold the lever 8 against its tumbler. Said lever at its free end engages a bell-hammer 13, arranged on a fulcrum 14, and is drawn into alarming contact with the bell i by a spring 15. The movement of the lever is limited and controlled by a stop 16, which holds the hammer normally away from the bell.
To allow the lever 8 to slide back to operative position after sounding an alarm in connection with the bellhammer,I have jointed the same, as shown clearly in Fig. 6, the end 17 being pivoted at 18 to the body of the lever. The said end 17 is so formed and disposed in its relation to the body as not to turn in its forward or alarming movement, but in its return movement it turns pivotally and rides over the end of the hammerlever. This action is secured by round-ing the portion of the end 17, which engages the body of the lever at one side thereof and making the opposite side angular, so that a shoulder is formed, which prevents pivotal movement when said shoulder engages the body portion of the lever.
It will be understood from the foregoing that the action resulting from the turning of the outside door-'knob is only to sound an alarm and that the action of the interior knob is to repress the latch-bolt 7c and allow the door to be opened, and such repression of the latch-bolt cannot be secured from the outside of the door except by a key, and even a key cannotopen the door lwhen the deadlatch fastens the key-tumbler p; but at all times the outside knob may be turned to produce an alarm. To secure this independence of action of the two knobs,l have jointed the knob-spindle so that one section works pivotally independent of the other. The preferred method of joining is shown in Fig. 10, where the sections are provided respectively with male and female threads, which hold the parts together, but allow the independent pivotal movement required.
Under some conditions it may be desirable to cut off the alarm mechanisms, and in this event I employ a repression-piece 20, attached to a turn-piece 2l, havinga pin 22 workingin an inclined slot 23, formed in acylindrical receptacle in the lock-case, which repressionpiece at its inner end engages the lever 8, and, when forced inward, throws said lever from engagement with the alarm-tumbler, as will be understood. V
The slight pressure of therepression-piece required to prevent the joined end or pawl17 from engaging the bell-hammer is entirely an end pressure, and thus the bearings of said piece on the turn-piece 2l and the end of the cylindrical part of the lock-case containing said turn-piece are sufficient to hold said repression-piece in position.
To cause the pivoted end 17 of the lever 8 to quickly return to its normal position, I may employ a weighted extension 34, which may be cast integral with said end piece or otherwlse.
Having thus described the invention, what Iclaim as new isl. The improved alarm lock herein described, in which is combined with the lock case, an alarm bell, a hammer for sounding an alarm thereon, a tumbler within said case for operating said hammer, a latch or locking bolt, c, and a sectional spindle provided with knobs on opposite sides of said lock case which are independently operable, one operating the tumbler for the alarm bell and the other the latch or bolt 7c, all substantially as set forth.
2. In an alarm lock, the case, the sectional p spindle, the `sections of which are independ- IOO IIO
ently operable from opposite sides of the door, tumblers arranged within-the lock case at pposite sides of the joint therein, a lever 8 having the pivoted end piece, 17, and havinga V shaped notch to receive the arm 7 of the tumbler, 6, said bell hammer and an alarm bell,
all arranged and combined substantially as set forth.
3. Incombinationwith the case of an alarm lock adapted to be inserted in the mortise of a door, a latch 7c spindle, e, in sections operable one independent of the other, tumblers arranged on said spindle, one at the side of the other on opposite sides of the joint in said spindle, a lever 8, having a pivoted end section, 17, a spring 12 holding said lever to one of said tumblers, a spring, o, holding latch, la, to the other, an alarm bell-hammer and bell engaged by the section 17, a key tumbler, p, for operating the latch Without operating the alarm, and knobs for operating the spindle sections from opposite sides of the door, substantially as set forth.
4. In an alarm lock.the combination with a sectional spindle and its knobs, tumblers arranged on said sections, one operating the latch bolt and the other the alarm bell mechanisms, said latch bolt and alarm mechanisms, a key tumbler for operating the latch bolt from the side of the door having the alarm bell-operating knob and a dead latch operable from the inside of the door to prevent repression of said latch bolt, all su bstantially as and for the purposes set forth.
5. In an alarm lock,the combination therein, of a sectional spindle one section of which operates alarm operating mechanisms and the other latch operating mechanisms, an alarm bell, and latch and said mechanisms for oper- 1 a key-tumbler adapted to operate the latch independently of the latch operating spindle and a dead lock for preventing the unlatching of the latch, substantially as set forth.
6. In an alarm lock, the combination with the latch, jointed lever 8, independent tumblers, jointed spindle and alarm mechanisms, a repression piece, 20, attached to a turn piece arranged in a slotted cylinder of the lock case and said lock case having said slotted cylinder and turn piece therein adapted to give longitudinal movement to the repression piece as the same is turned to throw the alarm mechanisms from the alarm-sounding position, substantially as set forth.
7. In an alarm lock, the combination with the slotted key tumbler and the latch operated thereby7 of the pivotal linger piece, f, and the sliding dead latch u, adapted to enter the slot of said `tumbler to lock said tumbler,
,ger'piece, substantially as set forth.
In testimony that I claim the foregoing I have hereunto set my hand this 20th dayl of October, 1893.
