sernrv DEVICE FOR LOOKS.

Specification of Letters Patent.

Patented Apr. 13, 1915.

Application filed October 7, 1914. Serial No. 865,488.

To all whom it may concern Be it known that we, GEORGE KoMARosE- virs and Garcon TRAIBER, subjects of the King of. Hungary, residing at Lorain, in the county of Lorain and State of Ohio, have invented certain new and useful Improvements in Safety )evices for Locks, of which the following is a specification.

T his invention relates to certain new and useful improvements in safety devices for looks.

lhe primary object of this invention is to provide a safety means adapted to be readily positioned within the key-hole slot of a lock and removably retained therein and preventing the entrance of the key for the manipulation of the lock structure.

A further object of the device is the provision of a two part safety means, one being employable for positioning the other within the keyhole of a lock and for displacing portions thereof to prevent its removal except by aid of the positioning means.

A still further object is to prevent the employment of any lock-actuating means by positioning a key-hole slot obstruction therein, the same being removably positioned and removed at will by aid of a positioning means.

With these general objects in view and others that will appear as the nature of the invention is better understood, the same consists the novel combination and arrangement of parts to be hereinafter more fully described, illustrated in the accompanying drawings and set forth in the appended claims.

in the drawings formin a part of this application and in which like-designating characters refer to corresponding parts throughout the several views, Figure 1 is a vertical longitudinal sectional view through a portion of a door and casing, a portion of one side of the door lock being broken away and the obstruction means illustrated positioned therein. Fig. 2 is a front edge view of the door partially shown in vertical transverse section upon the plane. of the key-hole slot of the lock, the obstruction means being shown in position. Fig. 3 is a horizontal sectional view through the key-hole slot of the door and lock with the obstruction means positioned therein and the positioning means in engagement there with. Fig. 1 is a view similar to Fig. 3 but with the obstruction means arranged for ready removal. Fig. 5 is an enlarged side elevation of the obstruction means partially broken away. Fig. 6 is a front elevation of the obstructing means. Fig. 7 is a trans verse sectional view taken upon line V 11-4111 013- Fig. 5, and Fig. 8 is a transverse sectional view taken upon lines VlIlVII1 of Fig. 5.

Referring more in detail to the drawings, the door 10 is illustrated with a lock casing 11 secured therein, the said casing having oppositely positioned key-hole slots 12 in alinement with the opposite key-hole slots of the door, all of which constitutes the usual arrangement of such elements.

lV hen the door is locked, it is desirable to prevent the entrance of a key or other lock manipulating means by any other than an authorized person and such a result is now efiiected by employing an obstruction means or element let which is readily positioned within and removed from the keyhole slot by means of a positioning means or element 15.

The obstruction means consists of a substantially key-shaped member having a cylindrical shank 16 and a lateral ward 17 projecting from one end thereof. A side plate 18 is journaled upon the shank by means of the sleeve 19, which sleeve is interrupted at its middle portion as at 20 allowing for the accommodation of a finger 21 carried by the plate 18 which engages the hexagonal portion 22 of said shank and forms a ratchet means for the turning of the plate upon the shank. A pin 22 prevents a removal of the plate 18.

The shank is provided with a reduced cylindrical end portion 23 at the end opposite to the ward 17 while the plate 18 is provided with a projecting hook 241 lying adjacent the reduced portion 23. A positionmg means 15 comprises a shank 25 having a central bore 26 at one end thereof adapted to be received for free revolution upon the reduced end portion 23 of the shank 16, while the said end of the shank 25 is reduced as at 27 for reception within the free end of the sleeve 19. A. side ward 28 having a perand positioning means 15 are employable With any manner of lock which provides an unobstructed key-hole slot extending from one side of the door to the other. By positioning the means 15 upon the obstruction means as illustrated in Fig. 4, the two members may be readily inserted into the lock as shown in said figure, and whereupon the ward 17 will be placed within the opposite slot from that through which it was inserted and as illustrated in Fig. 3, a turning of the member 15 a partial rotation will position the plate 18 at an angle to the ward 17 thereby placing the obstruction means in such a manner as to prevent its ready removal from the lock. The shank 25 is then rotated in a reverse direction upon the reduced end 23 thus releasing the hook :24: and allowing the positioning means to be removed from the key-hole slot by bringing the Ward 29 in alinement with the slot. When desired to remove the obstruction means from the lock, the means 25 is reinserted and turned for re'e'ngagement with the hook 24 and whereupon a continued revolving of the shank 25 brings the plate 18 into alinement with the ward 17 so that the obstruction device may be readily removed from the lockthrough either one of the keyhole slots.

The plate 18 is slightly retained at any angle with respect to the ward 17 by means of the resilient engagement of the finger 21 with one of the faces of the shank portion 22., It will be evident that with the member 14: positioned within the lock, the usual key orany other instrument can not be inserted through either key-hole for successfully manipulating the lock mechanism, while the obstruction means may be readily removed by the member 15.

While the forms of the invention herein shown and described are what are believed to be the preferred embodiments thereof, it is nevertheless to be understood that minor Copies of this patent may be obtained for changes may be made without departing from the spirit and scope of the invention as set forth in the claims.

What we claim as new is 1. A lock device comprising in combination with a lock having opposite key-hole slots therethrough, an obstruction member comprising a shank having a reduced cylindrical end and an intermediate hexagonal portion, a lateral ward upon said shank at the end thereof opposite to the cylindrical end thereof, a plate at the side of said shank and revolubly journaled thereon and having a cut-away portion adjacent the hexagonal portion of the shank and a resilient finger carried by said plate engaging the said hexagonal portion.

2. A look guard comprising an obstruction means consisting oi a shank having a reduced portion at one end, lateral ward rigidly secured to the other end of said shank, a plate journaled upon said shank and having a middle cut-away portion, a pin' carried by said shank and engaging within the cut-away portion of said plate, flattened surfaces upon said shank, a resilient finger carried by said plate and engaging the said surfaces, an end hook provided upon said plate, a positioning memher having a shank provided with an end bore adapted for turning upon the said reduced portion of the obstruction means shank, and a perforated side ward carried by said positioning means engageable with the said hook during the turning movement of the plate.

In testimony whereof we aiiix our signatures in presence of witnesses.
