Application filed January 28, 1919. Serial No. 273,518.
doors and the like and arranged with a number of simultaneously actuated bolts to permit securely locking the door against opening by burglars and other unauthorized persons.
Another object of the invention is to provide a lock which is simple and durable in construction and not liable to get out of order easily.
A still further object of the invention is to provide a lock, the bolts of which can be secured against sliding motion by means especially devised to accomplish this purpose and the key-hole of which can be closed against the entrance of a key and peeping.
These and other objects are attained by the novel construction and combination of parts hereinafter described and shown in the accompanying drawing, forming part of this specification, in which:-
Figure 1 is a plan view of a lock made in accordance with the invention, the cover plate being removed.
Fig. 2 is an end view of the lock.
Fig; 3 is a front view thereof with the cover plate in. position.-
Fig. 4 shows a key used to manipulate the 'lock.
Fig. 5 shows a key for operating the bolt locking mechanism.
Fig. 6 shows a sleeve used in connection with the key. ,1 Fig. 7 shows a device for closing the keyhole of the lock.
The casing 10 of the lock is provided with the customary cover 11 adapted to-be secured thereto by means of screws or the like, and the lock is provided with the usual latch bolt 12 controlled by. a spindle 13 of a knob 15 secured to said spindle by the customary sleeve 14. A de ressi0n'16 is provided within the lock casmg, in which is mounted a slide 17, the upper and lower parallel horizontal bars 18 and 19 of which represent the sliding bolts. The lower, 19, of which is provided at its lower inner side with a pcculiarly shaped recess 19 for engagement by a key for actuating said sliding bolts. A
. From the ibregoing description it will be clear, that any person desiring to open the lock, must first separate the 'key '37 and key 35 by pressing the spring 42 inwardly 55 tion, and means connected with said bar for to disengage the hooked end thereof from its engagement with the shoulder 44' of the recess 44. When then the end ll of the key 37 is introduced into the hub of the gear it can operate the same to shift the vertical bar downward "in orderto release the pins 29 and 30 from their engagement with the used to engage the recess 19' for retracting bolts 18 and 19, whereafter the key is the bolt frame and the bolts which are then looked in their retracted position by means of the pins 29 and 30 which sliding along the upper edge of bolts 18 and 19 drop auto matically by their own weight into the recesses 31 and 32. It will be clear that during this operation ,the bolt frame is moved backward by the key 36 against the action of spring 20.
While in the. foregoing there has been illustrated in the drawing and described in the specification such combination and arrangement of elements as constitute the preferred embodiment of this invention, it is clear that such minor changes may be made in the elements coming within the scope of the invention without departing from the s irit thereof.-
Havingt us described my invention, what I claim is 1. In a lock, the combination with a C38- ing and :a pair of latch bolts forming a frame slldab le therein, a spring for normally projecting said bolts into their lockmg position, ade ression in said casing, avertical bar provi ed with teeth at its lower end adapted to slide in said depression, pins within said depression, arms pivotally secured to said vertical bar and to said pins,
lugs secured to the free ends of said arms, pins extending from the lower ends of said lugs and adapted to be pressed into suitable recesses in said bolts for locking the same in their retracted position, means for disen-j gaging said pins from said recesses and "meansfor retracting said bolts after such disengagement.
2. In a lock, the combination with a cas- I ing, and a pair of springactuated latch ception of a-key cross-shaped in cross-seclocking the bolts in their retracted position upon the operation of said gear by a key, and means for projecting said bolts upon the disengagement of said locking means from said bolts.
. 3. In a lock, the combination with a casing, and a pair of spring actuated latch bolts forming a frame slidable in a depression of said casing, means for retracting said bolts from'their locking position, means for locking said bolts in this position, means for releasing said locking means, means for projecting said bolts upon the release by said locking means, a knob on said casing,
.and a key-hole-guard on the spindle of said knob for closing the key-hole opening.
4. In a lock, the combination with a casing having a depression therein, a frame sliding in said' depression, the horizontal bars of said frame constituting two latch bolts having recesses near their front ends in their upper. edges, shoulders formed in said depression of the casing, a spring secured with one ofits ends to one of said shoulders, the other end bent upon itself.
and resting in a recess of one of said-bolts, for normally holding said bolts in their projected position, a vertical rod slidable in the depression of the casing behind said bolts, teeth at the lower end of said rod, a gear meshing with said teeth, agrooved cross-shaped hub on said gear adapted for the receptionof the similarly shaped end of a key for operating said rod, a recess in the lower bolt for the engagement by the beard of a key for retracting said bolts against the action of said spring, two arms pivotally secured with their inner ends to said rod above said bolts, pins in said depression to which said arms are pivotally secured intermediatetheir ends, lugs pivotally secured to the outer free ends of said arms, pins extending from theunderside of said lugs and adapted to enter corresponding recesses in the upper edges of the bolts near their front ends, a knob, a spindle for said knob and a key-hole guard on said spindle.
In testimony whereof I have signed .my name to this specification in the presence of two subscribing witnesses, this 11 day of January, 1919. j I
