Application filed December 12, 1917'. Serial No. 206,768.

To all whom it may concern:

Be it knownfthat I, HENRY G. Verena, a citizen of the United States, residing in the town of New Britain, in the county of Hartford, State of certain new and useful Improvements in Locks, of which the following is a full, clear,

and exact description. This invention relates to key-controlled locking means for levers, and more particularly to key-controlled means. for locking the throttle or speed-control lever for automobiles. A

The principal object of this invention is to provide a key-controlled locking means by which a pivoted lever may be locked to its cooperating bracket so that the lever cannot be moved until it is unlockedby. the person having the proper key. 7

Another object of the invention is to pro vide locking means for a lever, consisting of but few parts, which parts are entirely in- .closed in the lever, so that the structure presents aneat and pleasing appearance. p

Still another object of this invention is to provide efficient locking means for a lever, so that it will be impossible for any unauthorized person to move the lever when it has been locked in place.

To these and other ends, the invention consists in thenovel features and combina tions of parts to be hereinafter described and claimed.

In the-accompanying drawings Figure 1 is a plan view of my key-controlled lever, shown mounted upon its supporting bracket; Fig. 2 is a side view of the same, showing 7 the lever partly in section andlocked against 40 movement; p v

Fig. 3 is a similar view to Fig. 2, but shows the lever unlocked and the latch disengaged from the cooperating notch in the bracket;

Fig. 4 shows an enlarged section taken-on the line 4..4 of Fig. 2; V

In the embodiment illustrated, 10 desigthe end of the handle.

flush with the outer Fig. 8 is an enlarged side view of an operating lever;

Figs. 9 and 10 .are enlarged perspective views of details of my invention; and

Fig. 11 is a transverse section through the nates a supporting bracket for the pivoted lever 11. This bracket is provided with an arc-shaped portion 10 concentric with the pivot for the lever 11. The bracket may be provided with a sleeve or collar 12 by which the bracket may be mounted upon the supporting post for the steering wheel of an automobile. The lever 11 may be pivotally mountedupon a bolt 13 mounted upon the bracket 10, which bolt may conveniently be provided with a nut 14 for holding the lever upon the bolt. The lever 11 is preferably provided with frictionmeans for holding the same in the desired adjustment upon the bracket, such as the spring-pressed shoe 15, which contacts with the inner surface of the arc-shaped portion 10. At one end of the arc-shaped portion is formed a stop 16, and at the opposite endis formed a stop having a projection 17 positioned to extend over the lever 11 when the lever is moved into contact with the stop upon which this projection is formed. Formed in the outer surface of the arc-shaped member 10 under the extension 17 is a notch 18, the object of which will be hereinafter described(. Upon the outer end of the lever 11 is formed a handle 19, and in the end of this handle is formed a threaded socket 20, in which is mounted a cylinder lock 21, the lock being provided with threads by which the same may be screwed into the socket formed in Adjacent the outer end of the socket 20 is formed a circular groove in which is seated the escutcheon 22 formed'upon the outer end of the cylinder lock, the arrangement bein such that when the lock is properly positioned within the socket 20, the outer face of the escutcheon is end of the handle 19 so that the lock is completely housed wit in the handle and the end of the handle is given The lock 21 is preferably provided with the well-known key-plug or barrel 21, which'may be locked against rotation by the well-known pin tumblers 21". Upon the inner end of the cylinder a neat appearance.

lock 21 is mounted a washer 23 having an eccentric opening therein through which the projecting-end 24 of the key-plug 21 extends. The washer 23 is held in place upon the inner end of the cylinder lock by screws 25, which screws serve also as stops to limit the angle through which the key barrel 21" .may.rotate, as'the key barrelis provided a form of a sector adjacent the key-slot 28.

This notch 27 forms a clearance space for a projection hereinafter descrlbed. When the lock 21 has been screwed into its proper position within the socket 20, the same may be secured against rotation in'either direction by providing a block 29 (seepartlcularly Fig. 10) having a lip 30 which engages a corresponding nick 31 formed in the inner edge of the escutcheon 22.

In the under side of the lever 11 is formed a deep slot 32 extending from adjacent the arc-shaped portion 10 to substantially the end of the handle 19. This slot, however, should terminate short of the end of the handle in order that a portion of the handle 33 may remain, to which portion the block 29 may be secured in looking engagement with the escutcheon 22 by means of a screw 34. Within the slot 32 adjacent the arcshaped member 10 is pivotally mounted the latch 35 (see particularly Fig. 9) by means of a rivet 36 or similar means. This latch is so positioned that it may be moved into looking engagement with the notch 18 when the lever 11 assumes a position directly over this notch. In order that the latch 35 may be operated by firmly grasping the handle 19, a long lever 37 is provided, which lever is pivotally mounted within the slot 32. by means of a rivet or similar means 38. The lever 37 is provided with a rounded inner end, which operates within the notch 39 formed in the latch 35, the arrangement being such that when the lever 37 is rocked about its pivot 38, the latch may be swung into. or out of engagement with the notch 18. The opposite end of the lever 37 is provided with a handle 37 on which is formed the projection 40 and the stop 41.

' The formation of the latch 35 and lever 37 is such that when these parts are mounted within the slot 32, they practically entirely fill up the slot and lle'substantially flush withrthe under face of the lever 11, so that the under side of the lever presents a neat appearance. The portion 37 of the lever 37 lies somewhat beyond the periphery of the handle 19, as shown particularly in Fig. 4, this arrangement being such that when the handle 19 is firmly grasped there will be a tendency to compress the outer end of the lever into the slot. The outer. end of the lever isnormally held in the position shown in Fig. 4 by a spring such as 42. The inward movement of this lever 37 is limited by the stop 41. It should be noted that the outer end of the handle 37 terminates adjacent the block-securing screw 34, this arrangement being such that while the lever 37 is mounted within its slot, it will be impossible to remove the screw 34.

The operation of the above described mechanism is as follows: The spring 42 tends to rock the lever 32 about its pivot so that the latch 35 is normally held in frictional engagement with the outer edge of the arcshaped member 10, the arrangement being such that when the lever 11 is moved directly over the notch 18 the latch is immediately moved into this notch by the spring 42 acting upon the'lever 37 The lever 11 will then be held against movement until the latch is withdrawn from the notch 18.

When it is desired to withdraw the latch 35 from its cooperating notch, the handle 19 is grasped so as to exert pressure upon the rounded portion 37 of the lever 37. In this manner the lever 37 may be rocked sufliciently to disengage the latch 35 from the notch 18, whereupon the lever v11 may be freely shifted 'over the arc-shaped member 10' about its pivot 13.

Should it be desired to lock the lever'll so that an unauthorized person cannot move the same, all that is necessary is to swing the lever over the notch 18, whereupon the latch 35 will immediately move into the notch, as above pointed out. In order toprevent the latch 35 from being withdrawn from the notch 18, the exten'sion24 formed upon the key-plug may be rotated by that the parts will assume the position shown in Fig. 4,'in which figure the clearance space or notch 27 is shown turned away from the so that the lever the latch 35. a 1

When it is desired to unlock the lever 11, the key 43 is inserted in its lock to rocannot be moved to operate tate the extension 24 so that the notch 27 assumes the position opposite the projection 40, as shown in Figs. 3 and 5, whereupon the lever 37 may be operated to withdraw the latch 35 from its locking engagement with the notch'18.

the key 43, so 1' projection 40 on the lever,

In order that the'key .may be removed from the lock when the key plug 21 is turned to the locked position indicated in Fig. 2 or the unlocked position indicated in Fig. 3 that is, in order that the key may be removed from its look when the lever 11 is either locked or unlocked, I provide two pin tumbler chambers in the cylinderlock 21, arranged at an angleto each' other as shown in Fig. 11. This arrangement of the pin tumbler. chambers, which is well-known and'need not be further here described, permits the key 43 to be inserted or removed when the key plug 21' is rotated to aline the pin tumblers with either pin tumbler chamber.

From the above description it will be seen that I have devised a very neat, compact and satisfactory key-controlled locking means for locking a lever so that the same cannot be moved by an unauthorized person.

Various changes may be made in the details of the construction without departing from the scope of the invention as defined in the claims.
