HANDLE LOCK.

Appntaaon ined March 4, 1922. 'serial No. 541,134.

My invention, while not limited in its ap* plication, relates more especially to that class of locks employed for locking spindles -ot' latches, knobs, cc., and an object ot' my invention, among others, is to provide a lock ot this class that shall be extremely strong` and particularly etiicient for the purpose ior which it is intended.

One torni ot lock embodying my 'invention, and in the construction and use oit which the objects herein set out, as well as others, may be attained, is illustrated in the accompanying drawings, in which- Figure 1 is atront view ot my iinproved lock shown as applied to a latch spindle having a handle secured thereto.

Figure 2 is a side view ol" the same. Figure 8 is a rear View with the handle broken oit.

Figure d is a view in section on aplane denoted by the dotted line lof Figure 5.

Figure 5 is a view in central longitudinal. section through my improved lock structure and with parts broken away to show conA struction.

Figure 6 is a view similar to Figure 5 and of' a portion thereof but showing the lock case in its unlocked position.

My invention, as hereinbefore stated, is

not limited in its application to any particular structure, but as it is especially adapted for the purposeo'f securing the spindle oi a latch as constructed for automobile doors against rotation, I have selected a structure oit' this class for the purpose of illustration ot my invention herein, the numeral 7 indicating a lock case that may be arranged in any suitable manner for insertion in a mortise, as in a door, and that to this end has a flange terminating` the edge of the face 8 of the case with ears 9 to receive screws or other astenings for securing the case in place. A latch spindle 10 entends through the case 7 and is provided with a handle l1, ot any suitable torni, rigidly secured thereto, a tip 12 ot the spindle being ot proper form, as square, for engagement or connection with the latch oit' a latch lock for a door, such parts and connections not being shown here in, as being oil ordinary construction theyl will be readily understood by those skilled in the art.

The spindle 1.() has a recess 13 to receive a spindle locking bolt 14 extending through an opening` 15 in a wall dividing the hole 16 'tor the spindle 'from a bolt chamber 1"? opening out from a barrel chaniber 18 in the l' wer part oi" the. lock case. y A. key barrel 1.9 containing a key cylinder 20 is located in thc chamber 18, this barrel and cylinder, so tar as the locking elements are roncerned, being ot any'ordinary construction, and for which reason a detailed description and illustration are omitted herein, the key center 2l only being shown. ji. crank pin 22 projects troni the inner end ot' the cylinder EEO into a notch in the side ot the bolt le', this notch 23 being oit considm crable .length to permit movement 'of the locking bolt independently of the pin 22.y This bolt may be igor. ed normally toward the spindle 10, as by means of a spring, said bolt.` pa. through an opening 2st from the interior ot the key barrel 19. A cap 25 closes the rear end oit the barrel chamber 18, and a spring or springs 27 located in an opening or openings in the key barrel and pressing against said cap operates to torce the key barrel to its outward position, and as shown in Figure 6 oit the drawing. A key slot closure QG is rotatably attached to the barrel 19 as a means tor closing the key slot when not in use.

1n the operation of the device, supposing the parts to be in locked position, as shown in Figure 5, insertion of a key in the key slot will position the tumblers so that the cylinder' 20 may be rotated, as by turning the key, and this will operate the crank pin 22 to withdraw the locking boltlt :trom engagement with the recess 18. immediately upon such withdrawal ot the locking bolt the spring or springs 2T will torce the key bi'irrel outwardly to the position shown in Figure G, in which position the locking bolt 11i will be carried to the forward part of the chamber 17 and out olf alignment with the opening 15, said bolt in this position resine' with its end against the bottom wall ot' the chamber. The parts being thus unlocked the siindle 10 may be freely turned to operate the latch to permit the door to which the parts are secured to be opened. To lock the parts it is necessary only to push the barrel 19 inwardly, .by pressure ot the thumb, the bolt le spring ing into locked position through the opening 15 and into the recess 13 when the bolt reaches a position to register with said opening and recess, and provided the latch spin dle is in proper position. If `said spindle is not in .proper position at this time, the locking bolt will rest against the side oi said spint-lle,` but just as soon as the latter is turned to cause engagement ot the latch with its keeper, the recess 13 will be located in proper posit-ion to `receive the locking bolt and thus lock the parts.

If it be desired that the bolt '1A shall-not automatically operate to lock the parts, the spring i'or actuating said bolt and as shown in Figure may be omitted, in which case the locking bolt Will `be moved to locked position only by operation of the key. My

invention contemplates any structure in which 'the locking bolt 14 is temporarily held against movement inV its unlocked position and by means of a member that may be mounted to move in various Ways to release 1f said bolt, and tvhile in accor-dance With the provisions of the patent statutes l have describedf'the principles 4ol operation of my invention, together with the device which l novv consider to represent the best embodiment thereof, I desire to have it understood operating member against movement.

2. As'pindle, amovably mounted operating membeiya locking bolt carried by said operating member, means to receive the locking I bolt 'to lock said 'operating "member agai-nst movement, means on the spindle to receive Isaid loekingb'olu and means to receive 'said locking bolt `to retain it in unlocked position.

'-3. A lock case having a #hole for a spindle and a lateralopening into said hole, va spindle rotatably mounted in said hole and having a recess adapted to register with said opening, an operating -member movably mounted in said case, a locking bolt carried on said operating member in position to pass, through said 4opening into the recessin said spindle, and means on the operating member :tor actuating said bolt.

4. Alock case having a hole for a spindle, a locking bolt chamber, and an opening from said chamber into said hole, a spindle rotatably mounted in said hole and having a locking bolt recess, an operating member movably' mounted in thecase, a locking bolt carried-by said operating member and `movable-thereby in said chamber to pass through said opening, and engagea recess in said spindle, or to `engage the Wall of said chamkey barrel v'movable 1in said key barrel chamber, a key operated member carried by said barrel, and la Vlocking bolt carried by said barrel and yoperatively engaged With-said key operatedl member, said-bolt being movable to pass through said opening into the recess in said spindle, V'orto be carried into position to Vstrike the bottom wall of said chamber.

6. A spindle, an operating member movably mounted, means for forcing said operating member iin one'direction, a locking bolt carried by said operat-ingmember to engage a recess in said spindlefto lock it against rotation, and means to receive said locking bolt'to lock said operatingmember.
