Application filed March 17, 1913.

To all whom it may concerti.'

Be it known that GEORGE A. VEHNER, a citizen of the United States, and a resident of Savannah, in the county of Chatham and State of Georgia, have invented a new and useful lmprovenient in PermutationLocks, of which the following is a speciication.

My invention is an improvement in permutation locks, and has for its object the provision oi a lock of the character speciiied, designed tor use with automobiles, and arranged to alternately connect a source of electrical energy with the motor to start the saine and with the magneto, wherein the lock is normally prevented from movement by releasable mechanism, operated by a selection from a plurality of push pins of a series, wherein the selection ot push pins .may be varied to provide for changes in the combination, and wherein the changing mechanism is normally locked in an inactive position and may be released only by operatand on its outer tace ywith a circular recess ing the proper selection of push pins.

ln the drawings: Figure 1 is a perspective view ot the improved lock, Fig. 2 is an enlarged vertical section, Fig. 3 is a rear view of the operating mechanism, Fig. 1- is a transverse vertical section of the operating dial or knob, showing the parts in one position, Fig. 5 is a similar view showing the parts in another position, Fig. 6 is a perspective view ot one of the push pins, Fig. 7 is a similar view of another'of the said pins, and Fig. 8 is a side view of the actuating sleeve of the lock.

The present embodiment of the invention is shown connected with a plate 1, which forms a closure for a receptacle or recess in that portion of the hood 2 of an automobile which is directly in front of the driver, and the opening of the recess is inclosed by a Jframe 3, secured to the hood, the plate 1 closing the opening of the saidframe and concealing the recess from view.

The trame 3 is secured to the plate 2 ot the hood by means of screws -1 or the like, and it will be noticed that the plate 1 is provided at its upper end with an inwardly Specification of Letters Patent.

,the ring or collar.v

A pin or rod 22 is arranged in the hub or bushing 17, the said rod having a head 23 Patented July 111, 1914.

the lower end thereof, and a' screw 10 is passed through the slot and threaded into the bolt 7, for operating the said bolt, the head ot' the screw being on the outer tace of the plate. Vlhen the bolt or latch 7 is moved upwardly in the bearing 8 by means of the screw 10, the lower end of the bolt releases its engagement with the trame 3, and the plate and its attachments may be removed from the opening in the plate 2 of the hood.

The bolt is provided with an inwardly offset upwardly extending lug 11, for a purpose to be described, and for the additional purpose of limiting the downward movelment of the bolt. That portion of the bolt which engages the frame 3 is outwardly offset to form a shoulder 12, between the said portion and the body of the bolt, and the said shoulder 12 engages a similar shoulder A13 on the plate to limit the upward move# ment of the bolt.

The plate 1 is provided near its upper end 111, and with an opening 15 at the center of ythe said recess. The operating sleeve 16 is 4.provided with a cylindrical hub or bushing at its outer end, and the inner end of the rod is conical as indicated at 24. The rod is vmovable longitudinally of the hub, and a 27 Vwhich tits outside of the said sleeve 16,

the body of the knob fitting within the sleeve and illing the same. The knob is also provided with an annular radial flange 28, which extends beyond the sleeve 27, and the outer tace of the said sleeve 27 is provided 'with a plurality of recesses29,`each of which has its side edges undercut as indicated at 30, and plates 31 are fitted in the recess, the said plates having their side edges beveled to engage the undercut walls 30 of the recess.

It will be noted from an inspection of Figs. 2, 4 and 5, that the body of the knob 26 is provided with two series yof radial openings 32, the members of each series being spaced at angular distances of 90o with respect to each other and the members of one series alternating with the members of the other series. A coil spring 33 is seated in each of the said openings, and a push pin engages the outer end of each spring. The operating sleeve 16 is provided with two annular series of circumferentially extending slots 34, each slot having a circular enlargement 34a at its center.

The push pins, before mentioned, are mov able in the slots 34, and the sleeve 27 of the knob is provided with openings registering with the slots 34 and with the openings 32 of the body of the knob. The curved plates 31 are provided with slots 35, the said slots extending to the outer edges of the plates for receiving the pins before mentioned.

The push pins are divided into two series, one series being arranged nearer the plate than the other. The pins are shown in Figs. 6 and 7 and each series consists of four pins, two as shown in Fig. 6 and two as shown in Fig. 7. Each of the pins shown in Fig. 6 comprises a head 36, a cylindrical inner end 37, a portion 38 substantially rectangular in cross section adjacenty to the head, a portion 39 substantially rectangular in crossl section adjacent to the inner end and a connection 40 between the v 41, which is the operating pin for the'mechanism to be operated. The said pin moves in an arc-shaped slot 42, in the plate 1, before mentioned. The sleeve 16 is prevented `from rotation on the plate by means of screws 43, which are passed through from .the rear face of the plate and engage the said sleeve to hold the same rigid with respect to the plate. On this account it will be evident that to permit the rotation of the knob to operate the pin 41, the push pins must be in such position that a iiattened orv substantially rectangular portion of .each pin will engage the slot 34 through which the pin` passes. All of the said pins are normally held in outward position by the springs and in the normal condition of the knob, any or all of the vsaid pins may be pressed inward without resistance. Certain ofthe pins however must be pressed inward to permit the rotation of the knob, and the other pins are so arranged that should any except the selected pins be pressed inward,

the knob cannot rotate. In other words, the selected pins and only the selected pins must be pressed inward to permit the knob to properly operate.

The pins are numbered o-n the face of the knob or dial as indicated in Fig. 1, the numbers running from l to 8 clockwise. It will benoted from an'inspection of Fig. 4 that two pins, namely 1 and 3, are out of registerv with the sleeve 16, that is, the said pins have their cylindrical portions 37 in the .portions 34L of the respective slots 34 of pressed inwardly will. prevent the rotation of the knob, and a 4positive series which must be pressed inbefore the knob can be rotated, and which in normal position will prevent the rotation of the knob. The firstnamed series are shown in Fig. 7 and the last-named in Fig. 6.

To change the combination ofthe knob or dial, the knob must be turned to the rightv or the left, after'the proper selection of pins have been operated to move the pin 41 from its position directly abovethe lug 11 of the bolt. stands directly above this lug, and prevent-s the movementfof the bolt. After the knob has been turned torelease the bolt, vthe bolt is pressed upwardly and the lower edge of the plate 1 is disengaged from` the opening lof the hood. The lifting outyof the lower end releases the upper end. The dial or knob is then removed from the plate by removing the setscrew 21 withdrawing the screws'43 and after the knob has been re-y moved, the plates 31 may be slipped out -wardly away from the flange 28' to permit the removal and replacement of the pushv pins. In this manner any desired combination or selection may be provided for and the combination may be changed as often as necessary.

lt will be noticed from an inspection of Fig. 3 that a pair of levers 7() and 70a is pivoted on the hub or bushing 17 of the operating sleeve. Each lever is provided at its upper end. with a lateral lug 71 and ay coil spring 72 is arranged between the-lugs. The lower end of the lever remote from the plate 1 is oiiset inwardly toward the plate7 as indicated at 73, to cause the llower ends of. the levers to lie in approximately vthe same plane, and the said lower ends of the levers engage on opposite sides of the pin 41.

The plate l is provided with'a stop 11a, and the said lower ends of the levers 7 Ol and 7 0n engage opposite sides of the stop.

It will be evident thatI when the pin l1 is moved in either direction, that lever toward whose lower end the pin is moved, will be swung away from the other lever, thus placing the spring 72 under tension. As for instance, when the pin is swung toward the lower end of the lever having the oliset portion 73, the said lever will be swung as indicated in dotted lines in Fig. 3, and as soon as pressure on the lever is released, the spring 7 2 will tend to return the lever to its original position, thus moving the pin Zil to normal position. The lever from which the pin moves is prevented from movement by the stop lla.

The operation of the lock is as follows: To permit the knob to turn, the push pins of the active series are pressed inwardly against the resistance of the springs, until the heads thereof engage the outer surfaces of the plates 3l. This movement of the pins moves the cylindrical portion of the said pins inwardly so that the said cylindrical portions no longer register' with the openings Saa of the sleeve 16, but instead a flat-tened portion, and the knob is ready to turn, the flattened portion of the push pins moving in the rslots Sil. The knob may be moved in either direction, and when restored to its original position and the pins are released, they are moved outward, thus again locking the knob to the sleeve. Should for inst-ance the combination be 1, l and 7, the

pins

1, 4 and 7 are depressed. Should any of the pins of the passive series be depressed the knob will be held from angular movement, even though the correct pins of the active series were in proper position, since the pins of the passive series normally stand with a tlattened portion registering with the slots 34.
