J. POWERS. KNOB SPINDLB FASTENER. APPLICATION FILED MAY 9,1910
Patented May 2, 1911.
Inventnr: 1707272; P0 wei-s.
UNTTED $TATE PATENT @FFTQE.
JOHN POWERS, 013 LOS ANGELES, CALIFORNIA.
KNOB-SEPINDLE FASTENER.
To all whom it may concern:
Be it known that I, JOHN PowERs, a citizen of the United States, residing at Los Angeles, county of Los Angeles, and State of California, have invented a new and useful Knob-Spindle Fastener, of which the following is a specification.
This invention relates to knob spindle fasteners for doors to prevent the unauthorized entering of a room while the room is occupied, and one of the main objects of the invention is to produce a device of the character described which is applied to the lock of the door independently of the key or lock bolt so that throwing back of the lock bolt does not affect the fastener, which is suflicicnt to hold the door in locked position.
Another object of the invention is to produce a device of the character described which may be applied to a common door look without changing the operating mechanism of the lock.
Another object of the invention is to produce a device of the character described of economical construction and simple operation.
Other objects and advantages will appear as hereinafter described.
Referring to the drawings: Figure 1 is an elevation, partly in section, of the edges of a door, showing an embodiment of the invention. Fig. 2 is a perspective view of a portion of the door showing the inside escutcheon plate. Fig. 3 is a sectional view on line w Fig. 1.
l designates a door having set into the stile 2 thereof a lock 3, of the usual form of door lock, provided with a latch bolt 4 and lock bolt 5. Escutcheon plates 6 and 7 are secured to the inside and outside of the door respectively by means of screws as shown at 8. The latch bolt 1 is operated by means of a square knob spindle 9 connected thereto by suitable mechanism, not shown, the ends of the knob spindle being secured in the shanks 10 of the door knobs 11 and 12 by means of screws 13 so that when either the inner or outer knob of the door is turned, the knob spindle is turned to throw the latch bolt back so that the door may be opened. The lock bolt 5 may be operated independently of the latch bolt by means of a suitable key inserted through either key hole 141- or 15 in the escutcheon plates 6 and 7 respectively.
The escutcheon plates 6 and 7 are each Specification of Letters Patent.
Application filed May 9, 1,910.
Patented May 2, 1911. Serial No. 560,368.
made of sheet metal having their edges turned back, as indicated at 16, so that the body portion of the plate is raised from the face of the door, leaving a space between the face of the door and the body portion of the plate. The fastener consists of a flat metal keeper plate 17 secured to the back of the plate 6 by means of studs 18 and 19 which pass through vertical slots 20 and 21 respectively in the plate 6. The upper stud 18 is provided with a head 22 and the lower stud with a flat finger grip or handle 23 on the outside of the plate 6 so that the keeper plate 17 may be moved vertically by gripping the handle 23 and moving the same vertically. The keeper plate 17 is frictionally held in elevated position by means of a flat spring 24 bearing against the back of the plate 6 and carried on the keeper plate 17 by means of the studs 18 and 19 which engage in slots 25 in the upper and lower edges of the spring 241. The keeper plate 17 is provided with a slot 26 which engages the square knob spindle 9 when moved into its upper position. When the keeper plate is in engagement with the knob spindle as above described, the knobs 11 or 12 cannot be turned to throw the latch bolt.
It is understood that the fastener is entirely independent of the lock bolt mechanism so that the door may also be locked with the lock bolt or not as may be desired, but should the lock bolt be thrown to unlock the door in any unauthorized manner from the outside of the door, the fastener would not be affected and the door would remain securely locked against intrusion. The only way the door may be opened is by lowering the keeper plate out of engagement with the square knob spindle, and this can only be accomplished by moving the handle 23 which is on the inside of the door.
What I claim is:
1. In combination with the square knob spindle of a lock, an inside fastener comprising an escutcheon plate having an upper and lower slot therein, a keeper plate movable vertically thereon and having a slot in its upper edge, upper and lower studs on said keeper plate extending through upper and lower slots in the escutcheon plate respectively, handle means on said lower stud outside of said escutcheon plate for moving said keeper plate to engage said square knob spindle in said slot in the keeper plate, and
elastic means carried on said keeper plate in sliding engagement with said escutoheon plate.
2. In combination with the square knob spindle of a lock, an inside fastener comprising an esouteheon plate having an upper and lower slot therein, a keeper plate movable vertically thereon and having a slotin its upper edge, upper and lower studs on said keeper plate'extending through upper and lower slots in the escutoheon plate respectively, handle means on said lower stud outside of said escutcheon plate for moving said keeper plate to engage said square knob spindle in said slot in the keeper plate, and
elastic means carried on said keeper plate in sliding engagement with said escutcheon plate, said elastic means consisting of a flat bowed spring having slots in its upper and lower edges in engagement with the upper 20 JOHN POWERS.
