R. ALLEN. KEY FASTENER. No. 287,991. Patented Nov. 6, 1883.
' Unirse Sterns Farmer @erica f i RCHARD ALLEN, `OF FREDERIOKSBURG, VIRGINIA, ASSIGNOR OF yONE-HALF TO JAMES F. THOMPSON, OF SAME PLACE.
KEY-FASTENER.
SPECIFCTION forming part of Letters Patent No. 287,991, dated November 6, 1883.
y Application filed Augustl, 1863. (No model.)
To afZZ whom it may concern.-
Be it known that I, RICHARD ALLEN, a citizen of the United States, residing at Freder- 'icksburg, in the county of Spottsylvania and State of Virginia, have invented certain new and useful Improvements in Key-Fasteners; and I do hereby declare the .following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. y
, This invention relates to devices for holding a key from being turned in the lock; and it consists in certain details of construction, as hereinafter pointed out and claimed.
The object of the invention is to produce a simple device for the purpose which may be attached to any lock.
In the drawings forming part of vthis specication, Figure l is an elevation showing the inside mechanism of niy key-fastener. Fig. 2 is a section of the sanne, showing the device applied to a lock and the key in position. Fig. 3 is a view similar to Fig. l of a modification. Fig. 4 shows a key with collar and spline. Fig. 5 is a side view ot' the casing; Fig. 6, a similar view of the disk; Fig. 7, a vieur of the slide.
c represents a casing of sheet metal, in appearance somewhat like an escutcheon. This casing is preferably struck up, but may be cast of light metal, and contains a recessed portion, a. Jthey-hole, c c', passes through-the casing, and when applied to a lock the key-hole in the casing comes in line With the keyhole in the door or lock. The casing may be secured to a door-lock by screws. To make the device complete, an inside plate, a?, may be applied, in which ease the operating parts will be inclosed between the plates a. c.
b is a disk with a key-hole, oc', therein. A
collar, b b2, projects from each side of the disk.
This collar is preferably integral with the disk, and is slotted or broken away at the narrow part ofthe key-hole. The disk b is placed in the recess a', and the collar b" passes through the large part of the keyhole in plate a.. The disk Z1 has a notch, d, in its edge, which notch has inclined shoulders, and another notch, e,
having square shoulders. A sliding piece, g,
is placed in the recess c', and has aprojection, g, 'which passes through a hole in plate u,
forming a iinger-piece outside said plate or casing. A spring, f, serves to slide this piece f in toward disk o, so that it has a tendency to drop into either notch in the disk which may be opposite the sliding piece. collar, i, and spline i at such distance from the end and bit that the spline will enter the slot in collar b b2 when the key is in place in the lock. (See Fig. 2.)
V/hen the device is applied to the door or lock, the key-hole in plate a and that in disk b is inline with the key-hole of the lock. At the saine time the slide g, pressed inward by spring f, engages notch d in disk b." The key may nonr be passed into the lock. On turning the key the spline e" thereon turns the disk b, the inclined sides oi' the notch d permitting the disk to force back the slide g. As soon as disk b has turned far enough to bring notch e under the slide, the latter, pressed downby its spring, Will fall into notch e and hold the disk from turning farther. This happens at the moment when the lock is fully locked. The diskt is now held from rotation by slide g, and by its engagement with the spline on the key holds the saine from being turned by nippers from the outside. The key is now in such position against the bolt of the lock that the same can not be picked. Vhen it is desired to turn the key, the slide y is lifted by the latch g until it is out of notch c, when the key and disk are free to turn.
Vhen the plate cZ is used, the key-hole there` in which is in line With that in plate a serves as a bearing for collar b2, and the disk b, the spring, and the main part of slide g are inclosed between the two plates. The slide g may have an extension which enters a slot in plate a2, as shown in Fig. 2, which serves as a guideor support to said slide.
I am aware that a key-fastening device has been known in which a notched disk was used, which closed the key-hole when turned to locking position. In such case the key had a springcatch which engaged with the escutchcon. I do not claim such a construction.
claini- 1. The combination of the inclosing-plate a., provided with a keyhole, the disk having key- The key has a 1 IOO hole to register therewith, said disk being spring-catch g, adapted to engage with said disk7 all arranged to engage with splined key,v as and for the purpose set forth.
2. The yCombination of the inelosing-plates (taz, provided with keyholes7 the round parts of which serve as bearings for the collar bbl, the notched disk 11, having key-hole and slotted collars7 and arranged With reference to plates a a2, as shown7 and the slide g5 actuated by a spring, and having a projecting finger-piece, 1o g', outside the easing, all arranged to operate with a splined key, and operating as set forth.
In testimony whereof I affix my signature in presence of two Witnesses.
RICHARD ALLEN. Witnesses:
