SAFETY-LOCK.
Specification of Letters Patent.
Patented April 16, 1907.
Application filed June 22, 1906- Serial No. 322,855-
and Improved Safety-Lock, of which the following is a full, clear, and exact description. My invention relates to lockssuch, for
instance, as are used upon doors, windows,
lo andanalogous closure members my more particular object being to provide a lock with means for preventing its being picked or actuated surreptitiously.
Reference is to be had to the accompanying drawings, forming a art. of this specification, in'which similar 0 aracter's of reference indicate corresponding parts in all the figures.
Figure 1 is a fragmentary horizontal section through a door and Lamb equipped with my improved safety-loo Fig. 2 is a side elevation of the outer facing-plate for the latch-socket and showing the safety-bar or projection; and Fig. 3 is a fragmentary side.
2 5 elevation showing the bolt projecting from the lock-casing and showing the safety-bar or projecting member used for the urpose 'of preventing the look from being pic ed.
The lock-casing is shown at 4 and is se- 0 cured in position by the aid of screws 5.- The knob is shown at 6, the key-bar at 6, and the safety-catch at 7'. The door is shown at 8 and is provided with a slot 9, through which pass threaded'bolts 10, these bolts engaging an escutcheon' 11 and being further connected therewith by means of a yoke 12. The tumbler-barrel is shown at 13, and a rib 14 is connected integrally therewith and with the yoke 12. The jambis shown at 16 and is separated from the door by the usual doorcrack 15.' .The latch-socket is shown at 17 and is secured rigidly u on the jamb by means of a bolt 18. This atch-socket is pro vided with an inner facing 19, integral therewith, and with an outer facing 20, fitted directly over the inner facing and re istering with the surface of the .jamb. other words, the innerfacing 19 and outer facing 20 are sunken into the jamb to such an 5 extent that the exposed surface of the outer with a de ression-28.
facing 20 comes flush with the edge of the jamb, as indicated in Fig. 1.
The outer facing 20 of the latch-socket is provided with a longitudinal head or projection 21 and with the usual socket or aperture 22. The inner facing 19 is provided with a slot 23, one boundary of which is slightly out of registry with the adjacent boundary of the slot 22. The inner facing 19 and outer facing 20 are connected together by rivets 24 and are provided with eyes 25 for receiving screws.
Connected rigidly with the casing 4 is a safety-bar 26, preferably secured thereto by soldering or fusing, and this bar projects into the slot 22, said bar also projecting a little way into the door-crack 15. The outer facing 20 is provided with a curved edge 27 and The bolt is shown at 29,and w ile provided with a generally hey- 17o eled surface this surface is broken up by corrugations 30, as indicated in Figs. 1 and 3.
The operation of m device is asfollows: The bolt 29 having een pushed into the socket 17 and secured rigidl so as to prevent 7 5 its withdrawal, the safetyars 26 21 effectively prevent the entrance of a knife or other implement ordinarily'used for the purpose of forcing the bolt 29 back into the casing 4. As will be observed in Fig. 1, if a'case-kn'ife 8c is inserted through the door-crack 15 it cannot pass the safety-bar 21 or projection unless the knife is crowded closel against the adjacent edge of the door 8. v n this event the knife cannot touch the latch 29, for the reason that it cannot pass the safety-bar 26. If owing to bad adjustment of the door upon its hinges or-to displacement or bad positioning of the socket 27 it should happen that a knife or analogous implement could be inserted so as to make contact with the bolt 29, the corrugations 30 arrest further movement of the knife, and thus revent the bolt from being pushed backward The great serious dangerin using spling- 5 looks is the fact that the bolt having, as ordinarily, a smooth beveled end can be pushed by merely the pressure of a knife or similar implement against its beveled endthat is to say, the beveled end acts somewhat upon 10o it and makes the path through which the.
knife might otherwise be" inserted still more tortuous.
I do not limit myself to the exact construc tion shown nor to the particular combination of arts described.
aving thus described my invention, I claim as new and desire to secure by Letters Patent V 1. A safety-lock, comprising a lock-casing adapted for attachment to the door, a latchsocket adapted for attachment to the faceof the jamb, said socket having an inner facing and a superimposed outer facing registering with the face of the edge of the jamb, said outer facing having a longitudinal rib for the purpose set forth, said facings being slotted, a safety-bar connected with the 'loolqcasing and projecting slightly into the slots of the facings, and having a portion projecting into the space between the door' and the jamb, a bolt slidably mounted in the lock-casing and I provided with a beveled end, said bevel fac g the safety-bar and being corrugated for the purpose set forth.
for attachment to the face of the jamb, said gsocket having a slotted facing adapted to register with the face of the edge of the j amb,
said facing having a longitudinal rib on the outer surface thereof, a safety-bar connected with the lock-casing and projecting slightly into-the slot of the facing, and a bolt slidably mounted in the lock, and having a beveled and, said beveled portion facing the safety- 3. A safety-lock comprising a lock-casing for attachment to the door, a latch-socket for attachment to the face of the jamb, said socket-having a slotted facing adapted to register with the face of the edge of the jamb, a'safety-bar connected with the lock-casing and projecting slightly into the slot of the facing, and having a portion adapted to pro ject between the door and the 'amb, and a bolt slid ably mounted in the loc -casing.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
