and residents,respectively,of Brooklyn, in

the county of Kings, and New York, in the county of Bronx, and State of New York, haveinvented certain new and' useful Improvements in Locks for'Vehicles,jof which the'following is a specification. 4 n f This invention relates to Vimprovements in locks, and more especially to locks for ve-` hicles,V and is a divisional application of an application iled'by us on February 25, 1915, Serial No. 10,515. Y v

The object of his-invention-is to provide a lock of this class which is simple in construction and easy to assemble and to ,securev VThe further lObject is to provide a device of this kind in which a' standardlock can loe used, andl when adrivelisv discharged a 1 new lock can be `substituted for 'the old lock.

The still further objects will appear from I a detailed description ofthe invention,

which consists in the features: of construc-V tion and comblnatlon ofparts hereinafter describedV and claimed and shown in the illustrations, of which--V Figurerl is an elevation of thecasing containing the spring actuated lockin'gmechanism and having the front plate removed and showing the mechanism in full lines in the locked. position and in dotted line'sin ,the open position; Fig. 2A is a side elevation,

partly broken away and showing almosta central sectional view of the casing; Fig. 3 is a perspective view of the casing; Fig. 4 is a side elevation Vof a wagon partly broken away to show one way in which the locking mechanism may be used; Fig. 5 is a plan view of the mechanism shown in Fig. 4, and

out departing from the spirit of our invention, and it is not thought necessary to illustrate the modifications, as they are obvious to those skilled in the art.- t

Referring to Figs. 1 to 3, it willY be seen that we provide a suitable casing 1 formed 17, '1915. sarialNa. 51,243.v

of two parts, andfforlconvenience we will deslgnate them as the front portion or part 2 and` the back 'portionor part 3. The back portion is formed with va flange 4, theV outer portion or edge vfitting the inside of the front portion 2, which isformed by thesidesV 5`fof the frontportion. The parts 2 and 3 are held together by the. bolts-6, which also securev the lock to the vehicle, but if desired other means may be used Ato secure the parts together independently of the bolts 6.'` 4'The part 3 is provided with studs 7 located in -bosses 8, and located upon the studs7 are two lspring actuated 'arms 9 which are held i in theirlocked position by the spring 10, Vwhich causestheir locking faces v11 tobear against the `rod'12,' `;which carries the lockfor the rod 12, which has its forward bearlng 17 -in the` extension 18 of thepart 2,'

and within theextension 18jis a chalnber'19 Y for the receptionof the'locking member 13. Located in the bore 20 is a .stud 2,1, and located on Vthe stud is "a double face,y cam 22, having cams 23 and 24 which Vactagairrlst' the faces 25 and 26 ofthe arms 9 to throw them -1 n open to releasetheflocking member ;13. -Vv The', ycam 22is under. the control of thelockv 27,

which. is of afsta'n'dard Inake' vand suitably secured in the extension 28'r andfhasl its ,tumbler barrel' in register 'withth'a "Stad 21 y 'and its operating link 29 extending into the rectangular opening 30 of the cam 22.

Referringto Figs. 4 and 5, in'which we have shown just enough of the mechanism to lillustratel one of the methods of using our lock, and it is not thought necessary to go 'pinto the details thereof, but it will be -seen that the vehicle is provided `with a foot lever 31 suitably secured to thevvagonand having a vlink 32 vconnecting it to the operating rod 33, which throws the plungers 34 out between the Vspokes Ofthewheels to rod 33 is connected tothe rod 12 by Vthe coupling 36, so that-it will be seeny that the rod 33 is controlled by the rod 12 and there- 'fore the rod 12 controls thev entire mechanism. f

The operation of this device is very sim@ Cio ple. When the `driver pushes the lever 31 forward, the link 32 causes the rods 33 and 12 to move forward and the mechanism in the casing 35 throws out the plungers 34 and at the vsame time the conical locking member 13 presses between, the faces 11 of the links 9 and forces them apart and passes into the chamber 19, and the spring 10 causes the faces 1l to snap behind the locking member 13 and thus holds everything in its looked position. When it is desired to release the vehicle, the key is inserted into the lock and given quarter of a turn, and the cam 22 turns, and the cams 23 and 211 acting against the faces 25 and 2G cause the arms 9 to swing apart and release the locking member 13, and the mechanism in the casing returns all the parts to their normal positions.

Having fully described our invention, it will be seen that we have accomplished the foregoing objects, and what we claim as our invention is:

1. The combination of a casing, inclosing a substantially flat chamber, a pair of arms pivoted in the vcasing to engage at their free ends, a spring connecting the .arms to yieldably retain them in engagement, the arms having registering channels at their engaging portions, the casing also having opposite extensions at one end to form a transversely extending chamber into which the engaging ends of the arms project, a plunger slidable in the transverse chamber extending between the arms, a conical abutment on the plunger arranged to engage the arms to separate them and to be locked in advanced position by the arms, the casing having an extension at an intermediate portion to provide a cylindrical chamber, a lock of the pin-cylinder type mounted in said chamber, a cam controlled by said lock and positioned between the arms to swing them apart on turning of the lock.

2. rI`he combination of a casing, a pair of f wthe arms having registering channels at their engaging portions, a plunger extending into the casing and between the arms at said channels, the plunger being slidable in a path parallel with the axes of the arms, a conical abutment on the plunger arranged to engage and swing the arms when advanced, and to be retained by the arms in advanced position, a lock extending into the casing, and a cam operated by the lock' and arranged to engage and swing the arms.

3. The combination of a casing, inclosing a substantially flat chamber, a pair of arms pivoted in the casing to engage at their free ends, the casing also having opposite extensions at one end to forma transversely extending chamber into which the engaging ends of the arms project, a plunger slidable in the transverse chamber and extending bctweeii the arms, an abutment on the plunger arranged to engage the arms to be locked in advanced position by the arms, the casing having an extension at an intermediate portion to provide a cylindrical chamber, a lock of the pin-cylinder type mounted in saidchamber, and a cam controlled by said lock and positioned between the arms to swing them apart on turning of the lock.

Signed at New York, in the county of New York and State of New York, this 4th day of September, A. D. 1915.
