LOCK.

Application led May 27, 1921.

To all '207mm t may concern Be it known that l, THOMAS F. WARD, a citizen oi' the United States, residing'at Cleveland, in the county oi Cuyahoga and State of Ohio, havey invented certain new and useful Improvements inLocks, of which the following is a specification.

This invention relates to improvements in locks and more particularly to that class of devices capable of use for a multiplicity of purposes and more particularly to sliding or swinging doors, and of such design as to constitute a spare tire lock or steering wheel lock for automobiles, and the like.

One of the objects of the invention resides in the construction of a lock of the type above set forth, wherein a pair of locking levers are adapted toy be engaged by the end of a reciprocating` rack bar movable by a key so as to release said levers from the keeper latch bar to unlock the same.

Another and very important object of the invention is the provision of a lock capable of universal use for various purposes and of such design that the parts will not readily get out otorde'r being extremely simple in construction, easily assembled, rigid and durable, highly eiiicientiin operation, practical yet capable of being manufactured at an extremely low cost whereby its commercial possibilities are greatly enhanced.

W ith these objects in view and others which will be manifest and suggested as the purpose and nature of my invention are'revealed in the following specification and drawing wherein l have shown a preferred embodiment thereof.

Figure 1 is a front view of the lock casing,

F 2 is a view of the casing showing the top broken away,

Fig. 3 is a sectional view taken on the line 3-3 of Fig. 2,

Fig. 4 is a viewshowing the invention as applied to a sliding door,

Fig. 5 is a sectional view oi the same,

Fig. 6 is a view showing the invention as applied and connected to the steering'wheel oi an automobile, and, Y

Fig. 7 is a view showing the invention as applied for locking a spare tire.

Referring now to the drawings, wherein like parts designate corresponding parts throughout the views. 5 designates a portion of a door and 6 the door j amb to which the lock is secured and operated in a manner now to be described in detail.V

Serial No. 472,960.

The lock proper consists of a front plate 7 which is partly cut away as shown at Sato be hingedly connected to the rear plate 8 by a pin 9 extending through bores formed in the respective plates 7 and 8 as clearly shown by Figs. l, 2 and 3 of the drawing. The rear wall 10 oi the lock is provided with a recess 11 near its outer end to permit a keeper 12 which is secured by suitable fastening elements 13 to the door jamb to extend within the body portion of the said lock to be engaged bythe mechanism subsequently to be described. 'This plate 8 is also secured by suitable fastening elements 14 to the door proper and is normally retained in the countersunk portion 15 of the rear wall 10 of the casing.

. The keeper 12 above referred to is in the nature of a cylindrical barrel 16, the top andbottom oit' which is open'to receive the curved ends 17, 18, respectively, of a pair of locking levers 19 each of which are shownpivoted at 20 and held in locking position by the coiled springs 21 secured thereto and to an eye22 attached tothe rear wall of the casing.

VThe opposite ends 25 of the levers are shown cut at an angle to conform with the triangular end 27 of a lever operating rack bar 28, the triangular portion of the bar being provided with lingers 29 adapted to engage the ends 25 or' the levers to rock the same on their pivots 2O and release the curved ends 18 from the keeper 16 above referred to. The opposite end 30 of the bar 28 is secured by a coiled spring 31 toone end of the easing, guide pins 32 beingprovided for the Vsaid bar 28 whereby the same Vwill properly engage the cut away portions of the locking levers when actuated.

Referring to Fig. 2, it will be noted that the bar 28 is provided with teeth 33 formed on the top thereof for cooperation with a key operated barrel 34 provided with segmental teeth 35 which are in constant engagement with the teeth 33 of the bar, said barrel of course being rotatable to the left or right to its operative and inoperative po-` sitions by the usual key adapted to be inserted in the keyhole shown at 36.

By reason of this construction, it will be readily apparent that when the key is in serted in the keyhole 36 of the barrel 34 and turned to the right for instance, the bar 28 will be actuated so that the fingers 29 will engage the ends 25 of the locking levers and release the opposite curved ends 17, 18 there- Y of from the keeper and thus the door may be opened. The pins 37 furthermore act inthe nature of a stop for the triangular portion.

ofthe bar 2S preventing the same from being withdrawn to a considerable degree by the coiled spring 31, the locking levers however being arranged to lie in proximity tol the triangular portion 27 of said bar 28 to be easily engaged thereby when the barrel 34 is rotated. It will be-furthermore ob'- served that the triangular portion 27 of the bar 28 and the pins 29 thereof are so ara section of a garagedoor 40 provided with` my novel and improved form of'lock above Y described wherein an eye 41 is adapted to be rotated to actuate the flexible elements 42,43 secured to a 'pair of top and bottom latches 44, 45 respectively, the bottom latch 45 in this instance, being operable by a connecting rod 47 whereby when the eye 41 is rotated the latch-will be released from the licor to permit the door to be opened. The connect-V ing rod 47 extends through suitable eyes 48 which are in the nature of guides and are attached to a spring latch49 which retains the upper end of a door stop 50, hingedly connected at 51 to the latch 45 so that when the member 49 is raised to the dotted line position 50 the hinged door stop will fall to its dotted line position as shown by Fig. 5Y

to retain the door open. y

In Fig. 6, I have shown my invention as applied to a steeringV post 53 and steering wheel 54 wherein the lock 55 may be secured to one of the wheel spokes 56 and hingedly connected at 57 by means of any suitable clamping device 58 whereby the saidy wheel 54 may be held in locking position and thus prevent unauthorized operation of the mo-V tor vehicle. Y

Similarly in Fig. 7 I have shown' my invention as applied as a locking means for a sparey tire 60, shown in dotted lines, in which the lock 61 is suitably secured to the respective sections 62, 63 of a clamping member, hingedly connected as at 64 whereby the tire may be removed when so desired by unlocking the said clamp.

In the accompanying drawings, I have illustrated my invention embodied in one form by way of example, and which in practice has been found to be Vhighly satisfactory in obtaining the desired results. It will be obvious however that other embodiments may be adopted and that various changes in the details of construction may be resorted to by those skilled in the art without departing from the spirit and scope of the in- Y vention. It is furthermore understood that the invention is not necessarily limited or restricted to the precise elements shown eX- cept in so for as such limitations are specilied in the subject matter being claimed.

I-laving shown and described my invention, what I now claim as new and desire to secure by Letters Patent of the U. S.- is
