COMBINED LOOK AND LATCH. No. 356,013. Patented J-an. 11, 1887 INVENTOR EINIIED grates ArnN ROBERT S. ROBERTSON, OF TORONTO, ONTARIO, CANADA, ASSIGNOR OF ONE-HALF TO PAMELA W. WRIGHT, OF SAME PLACE.
COMBINED LOCK ANDLATCH.
SPECIFICATION forming part of Letters Patent No. 356,013, dated January 11, 1887.
Application filed December 26, 1885; Renewed November 4, 1886. Serial No. 218,018. (No model.)
To all whom it may concern:
Be it known that I, ROBERT SMITH ROBERT- SON, of Toronto, Province of Ontario, Dominion of Canada, have invented a new and useful 5 Improvement in Combined Locks and Latches;
and I declare the following to be a full, clear,
and exact description of the same, such as will fi dnable othersskilled in the art to which it per ains to make and use it, reference being had the accompanying drawings, which form a part of this specification.
' My invention has for its object the construction of an improved door lock and latch which shall be simple and efficient in its operation,
not likely to get out of order, and which shall be strong and durable.
The invention consists in the combination of devices hereinafter described and claimed, reference being had to the accompanying 1o drawings, in which- Figure l is a side elevation with the cover of the case removed, showing the location of the interior mechanism when the latch is thrown forward, but not locked. Fig. 2 is a similar view showing the bolt retracted into the case and the interior mechanism in its corresponding'position. Fig. 3 is a view in perspective showing the construction of the bolt and bolt-frame, together with the slide which 0 reciprocates therein.
I carry out my invention as follows:
A represents the case.
a a are the screws which secure the cover upon the case; (t the key-hole.
B is the spindle; B, the socket which receives the spindle, said socket provided with arms I) b, so that the device may be operative whichever way the spindle may be thrown.
G is the bolt or latch, which may be con- 40 structed with any suitable frame, 0, and constructed at the rear to receive the impact of the arms 7) b of the spindle-socket,'so as to retract the bolt by the engagement of either arm therewith, as shown at c c. The bolt or latch I prefer to make integral with this frame.
The sides of the frame are slotted, as shown at c c, to receive a tumbler, D, and permit said tumbler to be reciprocated in said slotted portion of the frame, as indicated in dotted lines.
The tumbler D is cut away upon one side, as
shown atd, to form a keyway, and also upon the opposite side toward one of the ends of the slide, as shown at d, so as to receive a stop, a", secured upon the case.
E is a keeper pivotally engaged upon said tumbler at one end, as shown at 6, so that its opposite end may be thrown slightly to and fro. One or more keepers may be used.
F is a spring acting against the movable end of said keeper. It may consist simply of a band located in a kerf at. c in one side of the boltframe. The outer end of the keeper is cutaway so as to leave engaging shoulders, as shown at e and c It will be seen that when the tumbler D is in the position shown in Fig. 2 and in full lines of Fig. 1 the orifice d is situated to permit the bolt to be withdrawn, the frame with the tumbler engaged therein moving inwardly to the'rear of the case, the socket or orifice 01 allowing the tumbler to ride back until its inner edge comes in contact with the stop a When the tumbler is thrown in the position just described, the bolt may be freely operated by the spindle. The forward end of theframe of the bolt may also be slotted, so as to ride past the adjacent engaging-screw, as shown at b When thelatch is in this position the device is unlocked, and may be readily locked by throwing the key so as to engage the edge d of the guideway portion of the tumbler.
This throws the notch 02 away from the stop a and brings the edge of the tumbler against said stop,preventing the withdrawal of the bolt. At the same time as the tumbler D is retracted to the limit of its reciprocation the spring, acting upon the free end of the keeper, will throw its movable end forward, so that the shoulder 0 will have a bearing against the adjacent edge of the bolt-frame, effectually preventing the reciprocation of the tumbler D in the opposite direction to unlock the deviceuntil the movable end of the keeper is thrown so as to bring said shoulder e away from engagement with the adjacent edge of the boltframe, permitting the tumbler D to be thrown in the opposite direction, or into the position shown in full lines in Figs. 1 and 2. i
The position which the tumbler D and the keeper E, with its spring F, will assume when they are thrown to lock the bolt is shown in dotted lines in'Fig. land in full linesin Fig. 3.
The key G is constructed in such-a manner that when it is desired to unlock the device it will first form a bearing against the keeper E, so as to throw its engaging shoulder out of engagement with the adjacent edge of the boltframe in a position to move into the adjacent socket in the bolt-frame. A further throw of the key will form a contact with the edge d? of the cut-away portion and force the tnmbler forward.
In Fig. 1 the edge of the key is shown at the limit of its engagement with said edge, the springs H serving to throw forward the bolt. The keeper forms in reality a latch peculiarly constructed and arranged, not likely to be displaced, and rendering the device difficult of operation by any but the key fitted thereto.
Should the key have atoo extended bearing against said keeper, it is evident that it would throw the keeper too far over and bring the shoulder 0 against the corresponding edge of the bolt frame, effectually preventing the movement of the tumbler.
Only a key exactly fitted to the lock will open the device, for if the keeper be not sufficiently pushed back, or if it be pushed back too far, the operation of the slide will be checked, and the opening of the lock effectually prevented.
From the simplicity of the construction of the mechanism herein shown and described it can be made of small size, and hence in compact form, so that when used as a mortiselock the door may be weakened to less extent than would be the case where larger locks were used.
I prefer to construct the bolt-frame O as shown in the drawings, the frame extended to the sides of the case and thence rearwardly. As so constructed the case itselfforms a guide for the reciprocation of the frame, the arms engaged by the spindle-socket being offset at the rear end of the frame, shortening thus the ar s of the spindle-socket and affording a guideway between them and the case for the springs which throw forward the bolt. This construction gives a very even pressure of the springs upon the frame in operating the bolts.
What I claim, and desire to protect by Letters Patent, is-
, 1. In a combined lock and latch, the combination of the lock-case provided with stop a, a bolt having a frame fitted within the lock-case and provided with projections c c and slots 0 0 a recessed tumbler adapted to engage said stop and slots, springsbearing against the rear end of the bolt-frame, and a spindle-socket having arms for engaging the projections c c of the bolt-frame, substantially as-described. I
2. In a combined lock and latch, the combination of a single bolt having a slotted frame. 0, provided with project-ions c c, a recessed tumbler adapted to engage said bolt-frame, springs H H, a spindle'socket having arms for engaging the projections c c, akeeper, E, having one end pivoted to the tumbler and its other end provided with shoulders e e, and a keeper-spring, F, substantially as described.
3. In a combined lock and latch, the combination of a case having stop a, a bolt having a frame fitted within said case and pro vided with projections c c and slots 0 0 a tumbler adapted to engage said slot-s and provided with recesses d d, a keeper having one end pivoted to the tumbler and provided at its other end with shoulders 6 6 a keeperspring, F, spindle B, spindle-socket B, provided with arms b b, and the springs H H, substantially as described.
45. In a combined lock and latch, the combination of a bolt having a-slotted frame, a reciprocating tumbler, a keeper pivoted to said tumbler and adapted to engage the bolt- ROBERT s. ROBERTSON. [L.S.]
