Application fild November4, 1916. Serial No. 129,487.

Toall w7wm it may concem: l

Be it known that we, EDWIN WILLIAM ROGERS. and THEODORE C. R]EBE, citizens of the United States, and residents of Chicago,

in the 'oounty of Cook and State of Illinois,

have invented certain neW and useful Improvements in Automobile-Looks, of whioh the following is a speoification.

Our invention relates to locking devices for automobiles and has partioular reference to an improvement upon the construction disclosed in the patent to Conley, 1181571, of May 2, 1916 and Rogers & Rogers, 1182586 of May 9, 1916.

One of the objects of the present construction is to provide a device which shall Combine the elements of security against tampering, simplicity and compaotness. The present structure presents one feature not possessed by either of the devices shown in the patents heretof0re referred to; that is, the feature of simultaneously locking the motive fluid and interrupting the supply of electrioal fluid for ignition purpos s.

In order to provide a locking device Which shall be in efi'ect impregnable to orparts constituting the operating means shall be confined within a casing which is itself locked. In the present device the casing has a removable Wall WhiCh is held in its proper position by l ocking mechanism operable in unison wi*ith the means for -locking the valve controlling the supply ofmotive fluid to the automobile engine. A construction such as referred to is covered broadly in the patent to Rogers & Rogers heretofore referred to, but the specific form here disclosed is of value because of its simplicity.

In order to simplify the mechanism and to provide for ease of assembling, we prefer to niount the look, thevalveoperating member, the electrical contact piece and the spring for controlling the parts all on the removable Wall of the casing. In that manner the assembling is facilitated. As a means for locking theremovable Wall in the casing, We. provide coperating hooks and lugs on the valve-operating member and the casing, the hooks and lugs being in engagement When the parts are in valve-look -ing position.

One of the principal advantages in the present construction is in that there 15 no the present construction is in that the parts may be unlocked by .the motor driver and the key returned to the drivers pocket, it being unnecessary t0 again insert the key in the look When the parts are moved to closed position; in fact, the look does not funotion at all during that operation. In short, the whole functmn of the look which is controlled by the key is to trip the parts. Therefore, effective tampering with the look is difiicult.

The invention Will be more readily understood oy reference to the accompanying drawings, wherein Figure 1 is a face view of,a locking device constructed in accordance With our invention;

Fig. 2 is a similar view in the absence of the removable end Wall of the casing;

Fig. 3 is a similar view With all the opt1irn of the parts to.the position of Fig. 5,

and

Fig. 8 is a vertical sectional view on the line 88 of Fig. 2.

Referring more particularly to the draW- ings, it Will be seen that the device contemplates the employment of a casing 10, hav ing a removable front Wall 11, the face of which is normally flush With the marginal edge of the casing. As a means for normally holding the removable Wall in position, We provide the flanged nut. 12. A valve-operating shaft 13 ternfinates in the casing, this shaft being preferably of the flexible type and being inclosed within an inasmuch as it is essential in the installation of the device to provide for angular adjustment of the arm 15 relative to the shaft, I provide in the upper end of the shaft a peripheral groove 16, withwhich a key 17 engages. By this means the set screW carried by the arm 15 may be loosened and the arm adjusted Withont danger of the shaft 13 being pulled away from the arm.

A lock is mounted axially of the casing within the rmovable Wall 11. The lock c'asing, indicated at 18, contains the parts of a Yale lock and acts as the support and center et rotation for a shaft-operating member 19. This member is in the form of a plate and is best shown in elevation in Fig. 2. Projecting from the upper edge thereof is an arm 20, adapted to be manually engaged. Projecting laterally in the opposite direction and from the diametrically opposite portion of the plate is a fork 21, which engages the bent end of the arm 15. Also projecting laterally from opposite sides of the plate at a point substantially ninety degrees from the arms 20, 21, are hooks 22, 23, adapted, when the plate is in locking position, to lie behind lugs 24, 25, respectively, best shown in Figs. 3 and 6. The plate 19 is held in suitable position with relatiorl to the look casing and the removable Wall by clamping nuts 26.

A. pair o f contact pieces having wire-engaging terminals 27, 28, are. secured through suitable insulating material to the bracket 29, best shown in Fig. 8. A. contact piece 30, which serves to makean electrical connection between the two contacts is mounted through insulation on a lateral extension 31 from the plate 19 and is, therefore, movable in unison with the plate and with the valveoperating shaft.

Pivoted at 32 on the plate 19 is a pawl,

the point 33 of which is adapted to engage behind a stop 34, best shown in Fig. 2, formed as a part of the casing. The opposite end of the pawl curves around the spring casing and is engaged by a coil spring 35, the opposite end of which is likewise connected to the plate 19. It Will be seen, theref0re, that as the parts, as viewed in Fig. 5, are moved clockwise under the action of the lever 20, the pawl Will be caused to' engage with the stop and lock the parts in proper position. In this position the valve 85 for interrupting the supply of motix e fiuid Will be in closed position while the contact piece 30 Will be out of engagement with the twocontacts. By the use of only the parts which have been heretofore described, the motor might be securely locked, but it could not be unlocked.

In orgler to unlock the parts and to cause the supply of electrical fluid to be continued, we provide on the lock barrel 36 a two-armed member 37. The arm 38 acts merely as a stop for contact with the pin 39, carried by the lock casing. The arm 40, however, has a laterally-projecting portion 41, which is adapted to contact the bent end of the aWl and to lift the point33 thereof out 0 engagement with the stop. A strong coil spring is.mounted around the lock casing, one end of the spring engaging with the arm 40, as indicated at 42, and the other end 43 of the spring engaging the fork 21. It Will be seen, therefore, that as the key is turned to inove the arm 40 to pawl-tripping position, the spring which We have indicated at 44 is further' energized in order to insure that the valve-opening action shall be coinplete. After the parts have been released and have snapped to the position of Fig. 5, the lock barrel is returned to normal position under the action of the spring 44, when the key may be removed. It is, therefore, onl necessary to manually move the lever 20 to secure the parts in valve-locking position.

The construction here disolosed is, of course, capable of much modification, and such modifications as would readily suggest themselves to those skilled in the art are considered as within the Scope of the appended claims.
