Specification of Letters Patent.
Patented July, 11, 1922.
Application filed May 22, 1917, Serial No. 170,124. Renewed- October 2; 1920. Serial'No. 414,338.
To all whom it may concern.
Be it known that I, CHARLES F. M RRAY, a citizen of the United States, and resident of Evanst-on', in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in AutomobileLocks, of which the following is a specification.
My invention relates to looks for vehicles and particularly to' a lock adapted to be applied to the transmission casing thereof.
An object in' the present construction is to provide a simple form of locking device which may be locatedwithin the transmissioncasing or. if desired, in the rear axle and by means of which the power transmitting shaft is securely and permanently locked against any forward movement of the vehicle. This provision, however, is ineffective unless the car can be moved a limited distance before the lock comes into action. This permits all the usual movements of the car 'as required by the municipalities when the car is left on the streets. It also permits the car. to be moved as required whenin public garages or other buildings.
- The present device whenvinlocked position will absolutely prevent extensive movement of, the car without disturbing the transmission casing. The arrangement is such that not only is the transmission shaft locked but the transmission casing is al'so locked against removal ofthe cover. Even though th'e'thief has plenty of time, access to the casing cannot be secured without destroying it.
The invention, will be more readily understood by reference to the accompanying drawing, wherein, V v
1 is a vertical sectional view through a transmission casing to which my improvement has-been applied;
Figs. 2, 3 ands: are sectional "views on the lines 2--2, 3-3, and 14 respectively of i Fig. 1; v
Fig. 5 is a bottom plan view showing the means for advancing the clutch spring into looking position, and k Fig. 6 is a bottom plan view showing the means forlocking the casing cover in place. In the drawings the transmission casing is shown at 10. Mounted therein are the usual 17, and consequently change speed gears which ,need not be specifically described. The drive shaft 11,
enters the casing and is connected to the englne. The driven shaft 12, extends rearwardly and is positively connected to the 7 drive wheels. Surrounding the shaft 12, and secured to the casing is a plate 13, having -a stop lug with a cylindrical extension 15.
mounted on a spline 16, carried by 12, is a worm gear 17, also having a cylindrical extension '18. Mounted within the Slidably cylindrical portion18, and anchored .to the powerful, helical spring" 22, which bear respectively against the cylin-- downwardly ex- 23, integral with I :the cover 24, of the transmission casing.
reciprowill be raised and lowered into and out or engagement with the periphery of the worm 17. As a means for reciprocating the member27, I provide the spring30, and the bell crank 31, connected to a wire or cable 32, which is accommodated within an armored conductor 33. This is connected to a lock 34, which may be mounted at a suitable point in the vehicle. The tendency of the spring 30, is to move the parts to tl fie P0511 tion shown in the drawings, and when in 10. The long end 39, of the .lever 35, is also substantially as described.-.

I
As an additional precaution against tam- In an automobile lock, the combination paring, I provide, as best shown in Fig. 6, with the transmission casing and propeller means for locking the 'coveron the transshaft, of a worm gear slidably mounted on mission case. This means comprises'a lever the shaft, a resilient clutch member con 35, pivoted at 36,;to the cover, and to which nectedto and movable with said gear, a rack rods 37, 38, are connected. These rods eX- adapted to be moved into and out of entend in opposite directions and engage with gagement with said gear, and locking means suitable recesses in "the body of the casing for securing said rack in locked position,
