Application filed -March 28, 1918. Serial No. 225,198.

To all whom t may conceq I11 Be it known that we, JOSEPH KoLEszAn, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, and JOHN GABosH, a subject of the Emperor of Austria, residing at Newark, in the county of Essex and State of New J ersey, have invented certain new and useful Improvements ink Locks, and we do hereby 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 characters of reference marked thereon, which form a part of this specification.

The present invention has reference, generally, to improvements in locks; and the invention has reference, more particularly, to a simple and novel construction of sliding bolt lock.

The invention has for its principal object .to provide a novel construction of sliding bolt lock, having a very simple tumbler mechanism, which may be easily operated by either a knobfrom lthe inside of the i door upon which it is arranged, or from the outside by a key.

provide a novel key-mechanism, which may be easily varied to accommodate changes in the wards governing the action of a proper key.

A still further obj ect of the present invention is to provide a novel safety mechanism l which may be utilized to render the lock inoperative by either key or knob.

i Other objects of the present invention, not

at this time more particularly enumerated,

will be clearly understood from the following detailed description of the same.

With the various objects of the present invention in view, the same comprises the novel sliding bolt-mechanism hereinafter set forth; and the invention consists furthermore,'in the novel arrangements and combinations of the various devices and parts, as well as in the details of the construction of the same, all of which will be more fully described in the following speciiication, andy then iinally embodied in pended thereto.

The invention is clearly illustrated in the accompanying drawings. in which:

' Figure 1 is a face view of the lock the claims apmechanism as applied upon the inside of a door or the like, the novel safety catch mechanism being moved to its 4operative position to prevent manipulation of the lock mechanism by either key or nger knob.

Fig. 2 vis a detail horizontal section of lthe same, taken on line 2 2 in said Fig 1,

looking downward; Fig 3 is a detaill longitudinal section through the casing, showing the interior mechanism, the bolt receiving socket being omitted, the same being taken on line 3 8 in said Fig. 2 looking in the direction of the arrow w; Fig. 4 is a vertical cross section taken on lines 4-4 in said Fig. 3, looking toward the left; and Fig. 5 is a detail vertical cross section taken on line knob device; and Fig. 7 is a vertical cross y section taken on line 7-7 in said Fig. 6 looking to the left.

Fig.8 is a back view of a slightly modified construction ofthe novel lock mechanism constructed without the safety catch, the back-plate being removed. to illustrate the arrangement of the interior mechanism; and Fig. 9 is a perspective view on a large scale, illustrating a variation of the key devices, as operatively associated with the lock tumbler.

Similar' characters of reference'are employed in all of the hereinabove described views, to indicate corresponding parts.

Referring now to said drawings, the reference character 1 indicates -a suitable casing for inclosing` the lock mechanism, the same having ianges 2 at its longitudinal edges, through which fastening screws 3 may be passed to attach said casing to a door al., or the like. Said casing is provided at each end with suitably arranged openings 5, through which the bolt of the mechanism may be projected. The reference character 6 indicates a bolt receiving socket-piece, also.A

having flanges 7 'through which fastening screws 8 may be passed to secure the socket- ,piece to a door-frame 9, or the like, in

/ through said casing, from the front walll thereof, 4are posts 10, adapted to receive the fastening screws 10 by meansv of which a back-plate 1l is secured in connection with said casing. Formed integrally with said back-plate 11 is a suitably located rearwardly projecting sleeve 12. Said sleeve extends outwardly through the body of said door 4, or the'like, through an opening 4 provided therein for the purpose, the same terminating in an escutcheon plate 13 fixed -upon the outer side of said door. The open extremity of said sleeve provides a key hole into which a proper key 14 may be inserted for the purpose of manipulating the lock mechanism.

Arranged Within said casing, so as to be capable of sliding longitudinally back and forth therein-is a bolt body 15, the 'same being `provided at each end with bolt-portion 16said bolt-portions being adapted to be respectively. projectedl through the bolt openings 5 `of the casing. The relation of said bolt-body ,15 to said casing is such, that when one bolt-,portion 16 is projected outwardly from one end ofthe casing, the opposite bolt-portion 16 is withdrawn into the casing. rllhisarrangement renders the boltmechanism reversible, that'l is capable of being used upon either a right or left door, or the like. j ,Y w

Formed in the front wall of said casing,

is a bearing portion 17, inwhich is journaled a spindle 18 having formedin connection therewith an annular coupling member 19, normally inclosed within a depressed seat 2O formed'on the inside of said front wall of Y the casing 1,`said coupling member vhaving notches 19 formed in" its periphery. Con-V nected with said spindle, beyond said coupling member 19, is a stem 21 which extends transversely through the interior of said cas- Ling beneath the bolt body 15, and thence centrally through said sleeve 12 of the backplate-,11. rlhe outwardly projecting end of said spindle 18 is provided withlra reduced extension 22 upon which is secured a linger- `piece or knob`23, by `means of a set-screw 24.

Rotatably mounted upon said stem 21 is the hub 25 of Va rollback or cam 26, and connected with said hub 25 is altubular eXtension 27 which projects linto -the inner end of said sleeve 12, and 'which is cut away at its free end to provide a male bit or clutch portion 28, adapted to be engaged by afproper key, as will be subsequently described.

P A coiled spring 29 arranged about said stem between said coupling member 19 and said hub 25 of the tumbler 26,' by its comrte assenze rllhe underside oflsaid bolt-body y15 is provided with a suitably located notch 30, the

respective sides 31 of which are adapted to u receive the engagement of the rollback or cam 26, when the latter is rotated in one direction or the other, thereby imparting a longitudinal thrust or movement, in one direction or the other, to said bolt devices.

Pivotally mounted upon a xed post proj ecting inwardly from the front wall ofsaid casing 1 is a detent arm 32.which extends along one side of the bolt body 15, and

which is provided at its upperl free end with a transverse detent-lug 33, adapted to project' laterallyv over the upper edge' of said' bolt body 15.l 'llhe upper edge of said bolt body 15 is provided with an upwardly projecting j stop-lug 34, subject'to the engagement, upon one side or the other, vlof said detent-lug 33, whereby the bolt device is maintained against longitudinal movement in either direction, when in either of .its projected positions. Said detent-arm is so positioned that i 'its lower marginal edge 32 crosses the notch 30 of the bolt body 15.

Connected with said casing 1, within its interior, is an anchor flug 35, and a tension producing lug 36, with which one end of a leaf spring 37 is engaged and thereby held, so that the free end of said spring will exert a downward yieldable ressure upon said The said ste1n21 may `-detent-arm 32, to normal yv hold its detentone or more ward pins 38, adapted to be pov sitioned in radial extension anywhere about the circumference thereof beyond the tubular extension 27 of said tumbler device.

The key 14 for operating the lock mechanism from the exterior of the door 4, or the likev is provided with a tubular key-stem 40, adapted to be inserted through the exterior end of said tubular sleeve 12 so as to telescope over said stem 21. Said tubular keystem 40 is cut away at its end to provide a female bit or clutch portion '41, adapted to` correspond with and to receive themale bit or clutch portion 28 of thc tumbler device when the key is fully and completely inserted. In order to guard against the manipulation of the lock mechanism by an improper key, the ward pin or pins 38 are provided, and the tubular key-stem 40 is slotted as at 42 to straddle said ward pin or pins 38, in1 such a manner as to permit 'the complete insertion of the key andthe mutual operative engagement of the same with the rollback or cam devices.

. When atproper key is thus inserted so that its female bit or clutch portion 41 operatively embraces the male bit or clutch portion 23 of the tumbler devices, the key may be turned. a rota-ry movement-of the hub 25' upon the rll`he turning of the key produces be provided `with 100 l Y jected position.

stem 21, and consequently swings the rollback or cam 26 upwardly into the notch '30. The upward swinging movement of said rollback or cam 26 as it enters the notch 30, also carries a portion of the free end of said rollback or cam into lifting engagement with said lower edge 39 of the detent-arm 32 (as shown in Fig. 6), causing the latter to swing upwardly againstv the yielding tension of said spring 37 ,'whereby the obstruction to the longitudinal movement 4of the bolt devices afforded by the engagement of said detent lug 33 with said stop-lug 34 of the boltbody l5 is removed, whereupon a continued rotationof said rollback or cam 26 carries the same into retracting engagement with a side 31 of the notch 30, thereby pressing back or retracting the bolt 16 from its pro- As the rollback or cam 26 moves on it passes away from the detent arm 32, so that the spring returns the same to engagement with the opposite side of said stop-lug 34, thereupon holding the bolt device against accidental or undesired projection at the side whence it was retracted.

To operate the bolt mechanism by means of the knob 23 from within the door 4, or the like, the knob 23 is first thrust inward and turned slightly, this inward thrusting and turning movement forcing the coupling member 19 out of its seat 20, and causing one or the other of its notches 19, to find and straddle the lower free end 43 of the rollback spring 29. l/Vhen the coupling member 19 is `thus engaged with the rollback or cam 26,

the rotation of the knob 23 is transmitted to the rollback or cam so that the saine may readily be caused to actuate the bolt mechanism to either project or retract the bolt as may be desired (as will be understood from an inspection of Figs. 6 and 7 of the drawings).

In order to prevent the actuation of the bolt mechanism, by either knob or key, the following safety device is provided:

Connected with the upper side wall of said casing l., in a proper location, is'a bearingportion 44 in Vwhich is journaled a vertical shaft 45. Connected with the inner or lower end of said shaft 45 is a lock-block 46, and connected with the upper or outer end of said shaft 45 is a crank-arm '47 terminating in an upturned finger-piece 48. When desired the crank-arm 47 is swung inwardly to turn said shaft 45, thereby turning the free end of said lock-block 46 over the end of said Ldetent-arm 32,' thus obstructing any lifting movement of the latter, and thereby preventing the disengagement of said detent-lug 33 from the stop-lug 34, thus rendering the bolt mechanism inoperative (as will be understoodfrom an inspection of Figs. l to 4 in- By turning the crank-arni 47 outward, the shaft 45 is rotated to turn the free end of said lock-block 46 away from the end of the detent-arm 32, leaving the latter, and consequently the whole bolt mechanism, free to be actuated (as will be understood from an inspection of Figs. 6 and 7 of the drawings).

In Figs. 8 and 9 of the drawings there is illustrated a slightly modified construction of the lock mechanism, the same being substantially similar to the construction above described, except for the omission of the safety device, and the illustration therein of the provision of a plurality of the key wards 38 on the stem 21. The parts of this construction are identified by the same reference characters hereinabove employed, so that further description is unnecessary.

It will be apparent that the present invention provides a very simple, cheap and coinplete lock mechanism, which has few parts,

and yet which can be easily varied to provide for alterations inthe opeiating keys, and which may also be provided with asiniple safety device for preventing actuation of the mechanism when desired.
