KEY-HOLDER.

SPECIFICATION forming part of Letters Patent NO. 756,064, dated March 29, 1904. Application filed August 28, 1903. Serial Nol71.115. (N0 model.)

To a. whom it may concern.-

Be it known that I, CHARLES T. SHERMAN, a citizen of the United States, residing at St. Louis, State of Missouri, have invented certain new and useful Improvements in Key-Holders, of which the following is a specification containing a full, clear, and exact description, reference being bad to the accompanying drawings, forming a part hereof.

My invention relates to improvements in key-holders; and it consists of the novel construction, combination, and arrangement of parts hereinafter shown, described, claimed.

In the drawings, Figure 1 is a perspective View of a door with parts broken away, showing my invention applied thereto. Fig. 2 is an elevation of adoor with parts broken away,

showing my invention applied thereto.

Referring to the drawings, 1 indicates the door, and 2 indicates the keyhole thereof. Secured to the door by means of screws 3 in the rear of said keyhole is a bracket I. Said bracket 4 has secured thereto and integral therewith bifurcated arms 5. Also secured to the door by means of screws 6, in front of the keyhole thereof, is another bracket 7, said bracket 7 being provided with integral arms 8, the upper one of said arms 8 being provided with a shoulder 9.

Pivoted between the bifurcated arms 5 of the bracket Iis a lever 10, said lever 10 being provided with a projecting portion 11 and the front end of said lever being provided with the vertical portion 12. The said lever 10 is made of spring metal. The brackets L and 7 are so disposed on the door as to bring the leand ver 10 in alinement with the upper portion of the keyhole 2.

13 indicates the key of ordinary construction, provided with the thumb portion H.

When the parts have been secured to the door as illustrated in Fig. 1, the key 13 is'inserted in the door and the door locked and the said key so turned in the door that the portion 14 assumes a horizontal position. The

free end of the lever 10 is then inserted between the arms 8 of the bracket 7, and the resiliency of the lever 10 causes the front end of the lever to rest against the shoulder 9 of the arm 8. In order to release the lever from the key, it is only necessary to spring down the front.'end portion of the lever 10, so that it disengages the shoulder 9.

By the use of this invention the key cannot be turned in the door by burglars or other unauthorized persons.

Having fully described my invention, what I claim is- A key-holder comprising brackets Land 7 having bifurcated arms 5 and 8, a shoulder 9 formed on one of the arms 8, and a springlever one end of which is pivoted between the arms 5 and the other end of which is adapted to be engaged with and disengaged from the shglulder 9 of the arm 8, substantially as specifie 1 In testimony whereof I have signed my name to this specification in presence of two subscribing witnesses. v

CHARLES T. SHERMAN. Witnesses:
