ELECTRIC SWITCH RECEPTACLE FOR DOOR LOCKS.
Application led December 2,
This invention is a novel improvement in electrical switch receptacles tor door locks adapted to be attached behind the standard tace plates ot door locks, preferably of the type having separably operable inside and outside lock bolts, said receptacle having switch means therein tor automatically opening` or closing a gap in the electrical circuit tor the lights or power and the like simultaneously with the unlocking or locking ot the outside lock bolt by turning the door key from the outside ot such room or build ing, the switch being unaillected when the door is locked or unlocked 'from the inside by turning the inside lock bolt.
A tru-ther object oit the invention is to provide a novel and universal insulated receptacle, containing a circuit making and breaking device adapted to lit any standard tace plate behind the door trame of a double lock-belt door lock, whereby when the doer is locked 'from the eutside the electrical lamp or power circuit within the room circuit will be broken, and when the door is unlocked on the outside the circuit will be closed.
Another object ol: the invention is to provide au inexpensive, simple and eilicient receptacle provided with simple electrical si. itch means therein having a minimum number ot parts whereby the up-keep 'for rcplacementvl of worn parts will be reduced to a ininin'ium.
l will explain the invention with reference to the accompanying drawing which illustrates one practical embodiment thereof to enable others te adopt and use the same; and will summarize in the claims the novel 'the L f of construction, and novel combinan i parijs tor which protection deins:
n l e a vertical section through the g the adjacent parte of the the switch open in dotted lines;
Fig. 2 is a viront view et 'the door trahie showing the tace plate with its openings tor the lock-bolts and latch;
Fig. y3 is a section on the line SW3, Fig. i. As chown in the drawing, the door A is 'of l with the usual standard door luck tra,
sich A f operated by' the door koch 1927. Serial No. 237,213.
A2; an inside lock-bolt A3 operated by a key (or handle) from the inside ot' the room or building; and an outside lock-bolt A4 operated by a key from the outside of the room, building; or the like, such double bolt locks being commonly used for hotel rooms, and in othce buildings and the like.
On the door frame B is a standard tace plate B preferably flush with the face of the door frame, and held in place by means or" countersunk screws B2 or the like in the usual manner, the plate B having the usual openings therein for the latch A, the inside lock-bolt A3, and the outside lock-bolt A, respectively.
My novel receptacle Containing the circuit making and breaking means comprises a cas- 1; l ot sheet metal, wrought iron, steel. fibre, or other suitable material, said casing being adapted to take the place of the ordinary striker or keeper, and being open at the side adjacent the face plate B and having flanges l at its ends adapted to bear against the inner tace of face plate B', the screws B2 tor securing the face plate B to the doorl frame B, also passing through pertorations in said flanges la whereby the receptacle will be retained within a recess B3 ot the door trame B behind the tace plate B but may be readily accessible upon removing the screws B2 and the tace plate. The interior of casing l, it made of metal, is preferably lined with sheet insulating material 2 fitted to the entire inner surface thereof.
Extending through one end of the casing l is a contact bolt 3 ot conducting material which passes through pertorations in the casing l and insulation 2, and also through a bushing t ot insulating material to sulate bolt 3 'from the casing l. The head et bolt 3 is preferably disposed within the casing, and an electrical conductor C is engaged with the outer en d ot bolt 3 between a lock washer 5, and an insulating washer (l lying adjacent the casing l, lock washer' 5 being engaged by a nut 3,
At the opposite end of the casing l is similarly mounted a bolt 7, in axial alignment with bolt 3, said bolt 7 also extending through the casing 1, and insulation 2, and having its enlarged head 7a disposed Within the casing for the purpose hereinafter set forth. Bolt Y also asses through an insulatingzbus'hing 4 and its outer end is engaged with a con'
