* KEY-HOLE GUARD.
EPBCIPICATION forming part of Letters Patent No. 355.421, dated January 4-, 1887.
Application filed April 22, 1886.
To all whom, it may concern:
Be it known that I, OSCAR STODDARD, a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigau, have invented certain new and useful linprovements in Key-Hole Guards; and I do 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, reference being had to the accompanying drawings, and
to the letters and figures of reference marked thereon,which form a part of this specification.
My present invention relates to the construction, in connection with the'long-armed roseplates of a door, of detachable and movable key-hole-plate sections, one of said sections being attached to the face of the door, the other adapted to be raised and lowered, both sections located on the back face of the rose-plates, covering an opening in said rose-plates.
The key-hole section located on the outside of the door I provide with means whereby the" operator from the inside of the house, after locking the door, may turn a projecting button, thereby raising or lowering the key-hole section, bringing the key-hole out of range with the keyhole in the lock of the door, preventing the insertion of a key or the picking of the lock from the outside; and myinvention consists in the arrangement of parts, as hereinafter set forth, and designated particularly in the claim.
In the drawings, forming a part of this specification, Figure 1 is an isometical view of my invention attached to a door, having parts broken away to'show the construction. Fig.
. sections; g g, key-holes in same.
2 is a back face view of the outside rose-plate and sliding section. Fig. v3 is a front view of the inner rose-plate broken away to show the fastening of the key-h le section. Fig. 1 is a detail to be described.
D represents sections of a door; P P, the rose-plates; B B, holes through which the knob-spindle works; S, space for the reception of the lock; R B, longitudinal openings in the rose-plates; O C, key-hole plates or I form a chamber, E, in the back face of each rose-plate sufficiently wide to receive the key-hole plates. The chambers are longer than the plates, so as Serial No. 199,733. (No model.)
' to allow raising or lowering said plates for the purposes hereinafter set forth.
The plate 0 is secured to the inner face of the door by means of screws a, (see Fig. 3,) locating it so that its key-hole will register with the key-holein the lock-case. The roseplate P is then placed over it, being secured to the door by means of screws in the usualv way. I form a hole, A, through said roseplate, having two or more slots, i 2', leading into said hole. (See Figs. 1 and 4..) Passing through the hole A is a sleeve, Z, having on its outer end a button, K. Said sleeve is provided with a longitudinal slot, e. n is a collar mounted on the sleeve and pressing against the inner face of the plate I, when the button Kis drawn out, as in Fig. 1.
s s are arms attached to the sleeve and fill the slots i t of the plate P, when in position of Fig. 1, and when the sleeve Z is forced inward;
as shown by dotted lines of Fig. 1, the arms shaft is journaled in the support 12, which is" attached to plate P by means of the screw a,
as clearly shown in Figs.'l and 2. The spurwheel 8 engages with the cogs tof the key-hole plate 0, as shown by dotted linesof Fig. 2. The rose-plate P and sliding key-hole plate 0 are located on the outside of the door, as shown in Fig. 1. A hole is formed through the door for the reception of the sleeve and shaft.
The parts are attached and operated as follows: The lock being placed within the door, the key-hole plate 0 is secured to the inner face of the door by screws a, so that its keyhole will register with the key-hole in the lockcase; the plate being detachable allows the setting of the keyhole to accommodate a high or when the button K is drawn out, thus locking -'h01e plate 0', shifting the key-hole 9 out of range with the key-hole of the lock-case, and to lock the key-hole plate in any desired posi tion the button is turned until the arms 8 s register with the slots it of the rose-plate,
the sleeve, preventing the moving of the keyhole plate 0. This attachment is designed especially for outside or front doors of residences.
Having thus set forth my present invention,
what I claim as new, and desire to secure by Letters Patent, is
In combination with the door and its lockcase, the open-faced rose-plates, the plate 0, attached to the door, the sliding plate 0, adapted to slide in the outer rose-plate and having a series of cogs t, the shaft d, carrying a pinion at one end and a lu gf, at the other, said shaft and lug adapted to engage with the sleeve having the longitudinal recess, the button K, and arms 8, said arms engaging with the channels z of the inner rose-plate, the collar n, and support b, as and for the purposes set forth.
In testimony whereof I aflix my signature in presence" of two witnesses.
OSCAR STODDARD.
