LOCK.

Specification of Letters Patent.

Patented Oct. 17, 1916.

Application filed April 19, 1916. Serial No. 92,139.

To all whom it may concern:

Be it known that I, OSCAR L. VANCE, a citizen of the United States, and a resident of Decatur, in the county of Adams and State of Indiana, have invented a certain new and useful Improvement in Locks, of which the following is a specification.

My present invention relates generally to looks and more particularly to a lock of the permutation type, adapted for general application in the uses to which looks are adapted, and particularly useful for locking the operating parts of an automobile in either operative or inoperative con-.

dition.

The preferred constructlon of my lnvention, applicable as-it is to various uses as hereinafter shown, will be better understood by reference to the following description, in connection with the accompanying drawings forming a part of this specification, and in which Figure 1 is a perspective view of my improved lock with connections for using the same in an automobile. Fig. 2 is a vertical longitudinal section through the. lock. Fig.

3 1s a cross, section taken substantially on line 3-3 of Fig. 2. Fig. 4 is a perspective view illustrating certain parts of the lock in detached relation. Fig. 5 is a view partly in elevation and partly in section, illustrat- ,ing a modified mounting for the lock in connection with the dash of an automobile. Fig. 6 is a sectional view illustrating application of the look as a mortise lock for doors, etc.. Fig.7 is a detail perspective view of the inner end of the shaft, constructed for use as in Fig. 6. Fig. 8 is a view, partly in elevation and partly broken away and in section, illustrating its use as an outside door lock, and Fig. 9 is a view similar to Fig. 'Yfor use in connection with Fig. 8.

Referring now to these figures, the lock as' proposed by my invention, and in each instance of its use, includes a cylindrical shaft 10 having lateral extensions 11 projecting in diametrically opposite directions from its outer end and forming a handle,

' and provided with an inner reduced portion 12 forming an annular shoulder 13 intermediate itsends and against which shoulder abuts a washer 14 mounted on the reduced portion 12. The shaft 10 is also provided with a longitudinally extending key slot 15 projecting substantially from its handle at the outer end thereof, to a point adacent the inner end, for the reception of a key 16 having an outer angular projection 17 forming a finger-piece adjacent the handle 11 of the shaft, and having an inner angular locking end 18. This key 16 is also provided at a point intermediate its ends with serrations or teeth 19 forming notches between them in which are seated the inner beveled edges 20, of permutation disks 21, 22, and 23, surrounding the central opening 241 of said disks which receive the reduced portion 12 of the shaft 10.

The disks 21, 22, and 23 are each also provided with a slot 25 at one point in its inner beveled edge 20, so that when the slots of the several disks are alined with the key 16, the latter may be moved lengthwise in the shaft groove 15, to and away from locked position.

lhe reduced portion 12 of the shaft extends through the central opening of the lock plate 26 having a hub portion 27 rovided at one face with recesses 28 an 29 at an angle of 90 with respect to one another, and each of which is adapted for the reception of the inner angular locking end 18 of the key 16, it being noted that the several permutation disks 21, 22, and 23, before mentioned, are of progressively increasing diameter and arranged between the 'lock plate 26 and the washer 14, so as to maintain the series of disks in position for ready adjustment in use. Each of the said disks is provided in its rear face with slots 30 diametrically opposite one another, and for the reception of bent extensions 31 of substantially concavo-convex spring plates inwardly in the direction of itslength and v in order to move its inner locking end 18 out of engagement with the recess 28 or the recess 29, and thus free the shaft 10 for rotation by manipulation of the handle 11, to insert or withdraw a locking bolt of a door or other structure, or open or close a valve and the like through suitable connections for this purpose.

As used in connection with a mortise door lock, as seen in Figs. 6 and 7, the inner end of the shaft 10 is provided with an angular extension 33 pivotally connected to one end of anarcuate bolt 34, so that rotation of the shaft 10 in opposite directions, serves to insert the bolt within and withdraw the same. from its keeper 35, dependent upon the direction of such rotation.

As shown in Figs. 8 and, 9, in connection with an ordinary outside lock, the inner end of the shaft 10 may be provided with an angular extension 36, directly movable upon rotation of the shaft into and out of its keeper 37 As shown in Figs. 1 and, 2, however, the shaft 10, adapted in this instance, for the control of a fuel .valve 38 within a fuel pipe 39, is connected to the valve by means of a flexible shaft (not shown) incased within a flexible casing 40, so that, upon leaving the automobile for any length of time, the operator may close and lock the valve 38 and thus prevent unwarranted use or manipulation of the car during his absence therefrom. In the latter instance, the inner end of the shaft 10 may also extend through a casing rear plate 43 of the casing, whereby to form a bearing for the shaft and eliminate longitudinal movement and rattling thereof, the plate 43 just mentioned being for this purpose in two parts, as seen in Fig. 1.

The casing 41 may be secured through an opening in the dash, indicated in dotted lines at 44 in Fig. 2, or may be extended within an angular tubular support 45 in turn attached to the dash 46, as shown in Fig. 5. In either instance, the casing 41 may have a pair of internal spring contact fingers 47 and 48 as most plainly seen in Fig. 3, the inner free ends of which are in movable contact with a portion of the inner surface of the shaft 10, and the latter may, at this point, be provided with an insulated surface 49 in which is embedded a contact plate 50. The ignition wires 51 and 52, as seen in Fig. 1, are led into the casing 41 and respectively connected to the contact fingers 47 and 48, so that, when the shaft 10 is turned and looking extension 18 of key 16 engaged within lock plate recess 28, as shown in Fig. 3, the ignition circuit will be completed, while,

when the shaft is turned to engage and lock' extension 18 within recess 29, the contact plate 50 will be moved away from the contact finger 48 and the circuit thus broken.

Rotativemovements of the shaft 10 are limited to the movement of the locking extension 18 between pins 53 and 54 projecting inwardly from the hub portion 27 of lock plate 26, so that, in the event of the use above described, interference of the extension 18 with the contact fingers 47 and 48 is prevented.

It is obvious, therefore, that a look as constructed in accordance with my invention, is simple, comparatively inexpensive, strong,

and durable, viewed in the light of other locks of the type, and is, in addition, capable of application to a great variety of uses in connection with which locks of this type are generally put, and arranged and adapted to be used in connection With various devices slot and having an angular finger piece adjacent the handle of the shaft, and an inner angular locking end for engagement within the locking recesses of the lock plate, said key having serrations intermediate its ends forming notches therebetween, a series of permutation disks surrounding the shaft and disposed between the said lock plate and the said washer, each of said disks having a beveled edge surrounding its central opening receiving the shaft to interfit one of the notches of the locking key and having a slot in its said edge through which the key may be moved in the direction of its length when alined therewith.
