BRIGGS, 0F MILWAUKEE, WISCONSIN, ASSIGNOR TO BRIGGS & STRATTON CORPORATION, OF MILWAUKEE, WISOON SIN, A CORPORATION 0F DELAWARE LOCK Application filed April 14,
Various types of locks have been designed and placed in use either for jointly or independently locking the transmission and ignition systems of automotive vehicles, and while these devices operate to deter the amateur from making unauthorized use of the car, the drivers frequently nullify the locking devices by leaving the keysin the locks, thus inviting the theft of their cars. It, therefore, is an object of this invention to'provide an improved lock, which is so designed that the ignition system of the motor cannot be disrupted to stop the motor without first removing the key.
Another object of this invention resides in the provision of an improved device for simultaneously locking the transmission and motor ignition system having means whereby the key must first be removed before the device can be actuated to stop the .motor and lock the transmission, thus affording protection against the unintentional leaving of the key in the lock by the operator.
It is another object of this invention to provide an improved device of the character described in which the lock dust cap or cover actuates means which prevent the manipulation of the device to disrupt the ignition circuit and lock the transmission while the'key is in the lock, but instantly upon the removal of the key, the device may be moved to ignition and gear locking position.
And a further ob]ect of this invention resides in the provision of an improved device of the character described, wherein a key is first inserted in the lock to initially open the same and upon removal of the key the lock instantly moves to full open position, the lock being actuated to lock the transmission and disconnect the car ignition system with the key removed from the lock to thus preclude the leaving of the key in the lock by the driver. I
With the above and other objects in view which will appear as the description proceeds, myinvention resides in the novel construction, combination and arrangement of parts substantially as hereinafter described and more particularly defined by the appended claims, it being understood that such changes 1926. Serial No. 101,980.
in the precise embodiment of the hereindisclosed invention may be made as come within the scope of the claims.
In the accompanying drawings, I have illustrated one complete example of the physical embodiment of my invention constructed according to the best mode I have so far devised for the practical application of the principles thereof, and in which Figure 1 is a view, partly in section and partly in elevation, showing a gear shift lever mechanism equipped with a lock device embodying the principles of my invention;
Figure 2 is a view, partly in section and partly in elevation, taken through Figure l on the plane of the line 2 2 and illustrating the manner in which the'lock is incorporated in the ignition circuit;
Figure 3 is a view looking down on the transmission cover on the plane of the line 3-3 of Figure 1;
Figure 4 is a fragmentary detailed view, partly in section and partly in elevation, illustratin the lock in its first or initial opening position prior to the removal of the key;
Figure 5 is a view taken transversely through Figure 4 on the plane of the line Figure 6 is a view similar to Figure 4 illustrating the lock after the removal of the key and its consequent movement to full open position;
Figure 7 is a fra mentary detailed view, partly in section and partly in elevation, illustrating the manner of connecting the locking cam with the dust cap or cover whereby the lock is prevented from full opening movement while the key is in place, and
Figure 8 is a view, partly in section and partly in top plan, taken through Figure 6 on the plane of the line 8-8 and illustrating a slightly modified construction.
Referring now more particularly to the accompanying drawings, in which like numerals designate like parts throughout the several views, 5 designates a bonnet portion formed on the cover 6 of a transmission housing 7 in which suitable gear devices, not shown, are mounted, thegear devices providing the change speed for the conventional 'automotive vehicleand bein ioperated selectively by means of two shiftlng rods 8 adapted to be selectively engaged by a gear shiit lever 9 havingla universal mounting in the bonnet 5 by means of a ball pivot 10. As is'customary in constructions of this character, the inner end portion 11 of the gear shift lever is moved laterally with the transmission gears in neutral or non-working position to engage in one of the shiftin devices 12 of the rod 8 so that a rearwar orv forward movement of the lever upper end will effect an opposite movement to the shifting device and the rod'with which the end 11 of the lever is engaged.
The levers 8 are slidably journaled in bearings 13 formed in the cover 6 and haverecesses or channels 14 formed therein adapted to register with a transverse bore or opening 15 in the cover 6 when the gearing is in -neutral position to facilitate the engagement l'oftwo pin members 16 therein. The pm members 16 have their outer ends tapered and' are adapted to be spread and consequently engaged with the rod recesses 14 by an actuating pin 17 slidably mounted in a bore 18 intersecting the bore 15, as best shown in Figures 1 and 2.
The actuating 4pin 17 is controlled by a lock device 19 mounted at a point convenient to the driver of the vehicle, which as illustrated in the drawings is in a boss or enlargement 20 formed as a continuation of vthe bonnet 5. The bore 18 is enlarged in diameter at its medial portion, as at 21, and at its extreme upper end is further enlarged in diameter in the boss 20 where it receives.
the locking device 19, as at 22, the shoulder 23 formed at the juncture between the bores 21 and 22.providing a rest or support for an insulatingplate or disc 24 to be later described.
'Y A locking barrel mounting head 25 is slidably mounted in the bore 2 2 and the actuating pin 17 is connected therewith so that movehead ment of the locking barrel mounting 1 The causes a similar movement to the pin head 25 is securedagainst rotation in the bore 22 but permitted a linnted vertical.
movement by a guide pin or stud 26 extended into thebore 22 and engaging in a guide slot or opening 27' in the side of the mounting head, the vertical movement of the mounting head being limited to the length of the slot 27 A locking pin 28 is transversely slidable in the lower ortion of the lock barrel mounting head an is'adapted to be projected from the side thereof to engage in a locking recess 29`in the wall of the bore 22. Thelocking in 28 is vextendable from and retractable 1nto the head'25 by a lock plug 30 rotatably mounted in the head in a manner customary in constructions of this character. The plug v30 has the' usual key receiving opening or recess 29 and permitting the head to move upwardly in the bore 22 carrying with 'it the actuating pin 17. As the locking pin is retracted from its recess the mounting head is instantly moved toward its outer osition by an expansile spring 33 confined between the inner end of the mounting head andan insulating washer 34 secured overa pair of contacts 35 carried by the insulating member 24.
The contacts 35 are of the spring linger type and normally bear against, the upper end portion of the actuating pin 17 on which a suitable insulator sleeve 36 is mounted, as best illustrated in figure' 6, the lower portion of the insulatorsleeve having ametallic ring or contact member 37 imbedded therein. When the mounting head is in its locked position illustrated in figures 1 and 2, the contact lingers engage with the insulating port1on of the sleeve 36, and when the mounting head is moved to its unlocked or raised position, as illustrated in figure 6, the contact lingers ride onto the metallic ring 37 and are thus electrically bridged. Each contact linger 35 is connected with a terminal block 38, mounted below the floor boards 39 of the vehicle, by conductors 40, which are included in the ignition system of the motor which is indicated diagrammatically as at 41, so that with the mounting head 25 in its upper position the contact fingers 35 are bridged and the continuity of the electrical circuit of the ignition system is completed.
While a majority of the automotive vehicles are equipped with transmission locks of various types, the purpose of the locks is nullilied either by the failure of the driver to lock the same when leavingthe vehicle, or else by the careless leaving of the key in the lock. The carelessness'of drivers invites the theft of cars and this invention provides means to make it essential that the transmission be locked before the ignition system of the car can be interrupted to stop the motor,
and which is further designed to make it contact ringv 37. To accomplish this, the opa spring 44. The'cover is fixed to the pin 43, as at 45, and the pin is rotatably mounted in the locking barrel mounting head, as best illustrated in Figures 4 to 7, the mounting head having a slot or opening 46 inregister with the bore in which the pin'43 is mounted to receive a cam or tail locking piece 47 iixed to the pivot pin. The spring 44 normally urging the cover over the plug 30 tends to retain the cam 47 in its slot 46 inwardly of the peripheral surface of the mounting head. Movement of the dust cap or cover from its normal position overthe plug 30 by the insertion of a key in the plug, projects the cam 47 outwardly of its recess 46 to engage in either of two recesses 48 and 49, to be later described.
The recesses 48 and 49 are formed in the wall of the bore 22 and receive the locking cam 47 when projected outwardly of its recess 46 and in alignment therewith, the recess 48 being located inwardly of the recess 49 and being'or` greater width. The width of the recess 48 is such that when the locking pin 28 is engaged in its recess 29 a movement of the dust cover to permit the insertion of the key in its slot will project the cam 47 outwardly to engage in the recess 48 adjacent its bottom or innermost portion and when the locking pin 28 is retracted from its recess the mounting head 25 moves outwardly under the force of the spring 33, a distance equal to the width of the recess 48. This initial opening movement of the mounting head is such that when the key 32 is withdrawn from its opening or slot and the cover 42 swings back to its normal position retracting the cam 47 into its recess 46, the locking pin 28 is freed of its recess 29 and the mounting head moved upwardly by the spring to its full uppermost position as dened by the lower portion of thevguide slot 27.
With the mounting head in its uppermost position the recesses 46 and 49 are in register so that should the driver re-insert the key 32 in the plug the movement of the dust cap or cover 42 to free the key opening instantly engages cam 47 in the recess 49 and prevents the movement of the mounting head into its' bore 22 to stop the motor and lock the transmission until the operator irst withdraws the key. It will be thus apparent that the inadvertent leaving of the key in the lock is absolutely prevented by this construction.
Assuming the parts to be in their positions illustrated in Figures 1 and 2, the transmission is locked and the continuity of the-motor ignition circuitinterrupted, and vbefore the motor can be started it is first necessary that the transmission lock be released and the contacts 35 be bridged by engagement with the erator first inserts the ke 32 in the slot 31, the dust cover moving t e locking cam 47 out of its recess 46 against the spring 44 and into the recess 48. The key is then rotated through 'approximately ninety degrees in a clockwise direction with reference to Figure 3 retracting the locking pin 28 from its recess 29, the energy of the spring 33 being released to move the mounting head upwardly. This initial movement of the mounting head is limited to the width of the opening or recess 48 by reason of the fact that the key 32 being in the lock the cover 42 is in its position illustrated by dotted line in Figure 5 and the locking cam 47 is engaged in the recess 48. In this position the transmission is still locked and the ignition system interrupted. The key 32 is then withdrawn from the slot 31, permitting the cover 42 to snap over the plug 30 under the action of its sprin 44 dlsengaging the locking cam 47 from t e recess 48 and permitting the further movement of the mounting head under the action of its spring 33 until the lower or bottom end of the slot 27 engages with the limit pin 26. At this point the recess 46 of the mounting head is in register with the recess 49 communicating with the bore 22 and should the key be reinserted in the lock, the cam 47 will be engaged in the recess 49 and the mounting head locked against movement to disconnect the motor ignition circuit until the key is withdrawn to thus prevent the inadvertent leaving of the key in the lock.
If desired, the recess 49 may be eliminated as illustrated in Fi re 8, in which construction the dust cover 1s secured over the plug 30 While the ignition is on and the transmission unlocked. One of the rods 8 may also be hprovided with a recess or channel 14', see
Figure 1, adapted to register with the adjacent bore 15 when in speed to permit the leaving of the vehicle inspeed to serve as a brake, as is often customary.
In someA instances 1t may be desirable to so construct the lock as to release the mechanical drive, at the same time retaining the igni-l tion system closed. This ma be accomlished by shortening the actuatlng pin memlier 17 so that when the lock proper has been moved to its initial unlocking position movev ment with the cam or tail piece 47 engaging the upper end of the recess 48 the locking pins 16 are free of the transmission rod recesses 14.
From the foregoing description taken in connection with the accompanying drawings, it will be readily evident to those skilled 'in the art to which an invention of the character described appertains, that I have provided a coincidental lock especially designed for use with automotive vehicles, which provides positive means of protection against the carelessness of drivers in leaving the key in the lock and thus inviting the theft of the car, and which is further designed to preclude the failure to lock the transmission in that the locking of the transmission is a prerequisite tothe stopping of the motoras the ignition system is connected in with the transmission lock.
What I claim as my invention is: 1. A lock device, ycomprising locking means, an actuating member for the locking means and vhaving a key receiving opening,
v and means carried by the actuating member and preventing the locking of the first means when a key is in the actuating member opening. v
2.
