lFURNI'LURE Lock.

Serial No. 465,610.

(GRANTED UNDER THE PRGVISINS F THE ACT 0F MARCH 3, 1921, 41 STAT. L., 1313.)

To all whom t may concern:

Be it known that 1, ADAM Snrrz, a citizen of the German Republic, andV a resident of Furth, Germany, have invented certain new .c and useful Improvements in Furniture Locks (for which l have filed applications in Germany, Apr. 3, 1919, Pat. No. 334,388; Austria, J an. 24, 1921; Belgium, J an. 26, 1921; Great Britain, J an. v28, 1921; France,

iu J an. 29, 1921), of which the following is a speciiication.

rllhis invention relates to a lock for articles or pieces of furniture and is distinguished from known locks with adjustable length of the stem by the feature that the lock-box is displaceably arranged upon guide-bars, as

well as upon rods attached to the bolt, s

described hereinafter.

1n order to make my invention more clear,

1 refer to the accompanying drawing, in which similar letters denote similar parts throughout the several views, and in which F ig. 1 is a front-view of the lock without its box-cover and F ig. 2 is a similar illustration showing the lock with the box-cover attached to it.

The lock mechanism al is displaceably arranged upon two guide-bars b riveted to the bolt-plate c by the intermediation of the plate a. The bars b b pass through sleeves a2 located at the rear of the plate a, and may be firmly connected therewith by means of screws g g. The bolt d may be connected with the lock-mechanism by rods e, e and by a screw 7L, as more fully described hereinafter; the lock-mechanism may be displaced upon these bars. To permit of a quick and reliable adjustment, the bolt d is provided with an abutment-ledge f, and to aord access to the screws h and z' of the lock the boxcover is provided with holes la and Z.

m and m1 are downwardly extending lugs which form parts of the lock mechanism and are the members that are connected by the screw 7L with the rods c e; they are, besides, the members acted on by the beard of the key, the one member or lug operating when the lock is being closed and the other operating when it is being opened.

The adjustment of the lock is effected in the following manner: First, the crews g are unscrewed. Then the bolt al is moved outward, as in Figs. 1 and 2, so that the fastening-screw it appears to be flush with the hole 7c and may, thus, also be unscrewed. To make the adjusting screw z' appear flush with the hole Z so that it may be unscrewed the boltd must be pushed back into the boltplate c. After the four adjusting screws have been unscrewed in this manner, the lock mechanism is adjusted to the length of stem desired by being displaced upon the rods mentioned, after which the four fastening screws are again screwed home.

Another reason for the manifold applicability of the lock is, that its box may be removed and turned for 180 so as to permit of employing it as righthand-or lefthandlock or as upper lock or transverse lock simply by being correspondingly turned.

Having now described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:

A furniture lock, comprising, in combination: a bolt plate and a bolt therein; bars extending forth from said plate and from said bolt; a lock-plate adapted to be displaced along said bolt plate bars, and means for connecting these bars with said plate; a lock-mechanism comprising key-operated locking members secured to the lock plate and having said bolt bars pass through it; and means to connect these bars with those lock members that are acted on by the beard of the key pertaining to the said lock. v

In testimony whereof I aiX my signature inr presence of two witnesses.

ADAM SEITZ.
