A. c. SAXTON AND H. J. MENARD. LOCK FOR CONTROLLING LEVE'HS.

APPLICATION FILED JULY 1-5. I916.

AUGUSTUS C. SAXTON'AND HENRY J. MENmD. OF CHICAGO, ILLINOIS, ASSIGNORS T H. R. MANUFACTURING COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLI- LOCK FOB CONTROLLING-LETTERS.

To all whom it may concern:

Be it known that we, AUeUs'rUs C. SAX- TON and HENRY J. MENARD, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in controlling levers of. automobiles and designed to cooperate with the transmission plate for locking the lever against surreptitious operation.

The above and other features of advantage and capabilities will become apparent from a detall description of the accompanying drawings, in which we have illustrated one form of. our invention, but the embodiment there shown is to be understood as illustrative only.

=Figure 1 is a cross-sectional new of a lock embodying our invention, shown mounted on a controlling. lever, the transmission plate and lever also being shown in cross-section, except for a portion of the latter. v

Fig. 2 is a view taken approximately on the line 2-2 of Fig. 1.

Referring to the drawings in detail, the

controlling lever 10 has slidably mounted thereon a lock casing 11, which casin is provided with two downwardly exten ing lugs 12, which, when the locking casing is in looking position, cooperate with and fit into the longitudinal slots of the transmission H plate 13. When the locking casing is in this position, as shown in Fig. 1,.it will thus be seen that the controlling lever 10 cannot be moved sidewise in either direction suiliciently to register with the longitudinal slots in the transmission plate and when the controlling lever is locked against surreptitious operation.

The lock casing 11 is provided with a key controlled lock, and means for automatically lifting the lock casing out of locking position when the lock bolt 14 is withdrawn by means of the key, which mechanism will Specification of Letters Patent.

now be described. The casing 11 is provided near its upper end with the circular internally screw threaded opening 15, designed to receive an externally threaded lock barrel 16, in which barrel is rotatably mounted a key controlled lock cylinder 17, in which is fixedly mounted a shank 18, which carries upon its end-a cam 19. Below the barrel 16 the casing is provided with three horizontally located bores, the middle one only of which is shown in Fig. 1, and in which middle bore is slidably mounted the locking bolt '14, which which upon its upper end is provided with the ball 20, which ball is at all times held in engagement with the cam 19, by means of compression springs (not shown) which are respectively mounted within the other mentioned bores, which bores are located one on each side of the middle bore. These compression springs are adapted to engage the ends of a cross pin extending through the locking bolt 14, and which cross pin is not shown in the drawing. The tendency of the compression spring is to at all times force the locking bolt 14 to the left to such an extent that the ball 20 is continuously in contact with the face of the cam 19. From this it will be seen that as the cylinder 17 is rotated in the proper direction, the bolt is withdrawn from the cavity 21 in the lever 10, thus permitting the casing 11 to be moved upwardly under action of the spring 22, the construction of which will now be described. Extending through an opening in the top of the casing 11 and slightly to one side of the lever 10 is the lift rod 23, which is connected at its upper end to the lever 10 by means of the pin 24, and at its lower end is screw threaded in a plug 25, which plug is provided with a bifurcated end designed to rest on the pin 26 connecting with the lever 10. Surrounding the lift rod 23 and confined between the upper end of the casing and the plug 25 is the compression spring 22, so that when the bolt 14 is withdrawn the I spring 22 will act to throw, the lock carrying carries upon its upper surface a vertical pin,

parts in looking position, all that is necessary is to place the foot upon the casing 11, pressing downward thereupon until the bolt 14 comes in registry with the cavity 21,

when it will under action of the springs enter therein, and thus securely lock the projections 12 in proper locking position, thus preventing any surreptitious movement of the operating lever while the owner is away from the machine. From the above description, it will be apparent that when the owner desires to again use the machine, all that is necessary is to insert the key within the lock barrel 17 and turn the same to remove the locking bolt 14, at which time o the casing, together with the locklng pro jections 12 will automatically fly upwardly under action of the spring 22, thus permitting the operatin lever 10 to be operated as desired. From his it will be seen that the only time the key is utilized is when withdrawing the bolt 14 from the cavity 21, and that it is not necessary for the operator to in any way resort to a key for locking the lever in a neutral position against surreptitious movement.

\Ve claim:

1. In a lock of the class described, a unitary casing adapted'to entirely surround a control lever, provided in its upper portion with a chamber, and provided at its bottom with integral, downwardly extending looking lugs on opposite sides of the lever adapted to engage a transmission plate, lockin means housed within said chamber, and a apted to engage said control lever and hold said casing in its looking position, and means housed within said chamber for automatically raising the locking member on the release of said locking means.

2. In an automobile lock of the class described, a hollow casing havin openings at the top and bottom through w ich a transmission lever may pass, fitting the top opening closely, and a side opening adapted to receive and contain locking and lock actuatin mechanisms, said casing being adapted to slide longitudinally along the transmission lever, and having on its lower end lugs adapted to enter the opening in and to engage 'a transmission plate and thereby prevent the lever from being shifted.

In testimony whereof, we hereunto subscribe our names to this specification inthe presence of two witnesses.
