KEYLESS LOCK.

Application filed September 24, 1924:. Serial No. 739,685..

To all whom it nmg concern:

Be it known that We, WILDRICK and ALEXANDER GiLoi-mrsr HA'ror-r, citizens of the United States, residing at Honolulu, 'lerritory of Hawaii, ha e invented certain new and useful Improven'ients in Keyless as will prevent the unauthorized opening or picking of the same, and-will also facilitate the operation of the lock.

Another object of this invention is to provide a lock with means which will normally urge it into open position, and which will automatically retract the locking member,

herein disclosed as abolt or look plate, as

soon as certain mechanical conditions are complied with for releasing the plate; thus 2 obviating the necessity 01" manual or other operation of parts for retracting the lock- I ing plate or member.

A further objectof the invention is to provide a lock embodying the above improved features, andwhich maybe incor porated in various types of locks, such as door locks, automobile locks, ignition locks, and various combined locks, wherein ignition and lighting circuits are controlled by a switch subject to the operation of the lock.

The invention still further aims at the provision of an improved locking plate or bolt member, which is adapted to secure from moventient the parts or members which are to be locked or secured,

provided with a spring acting on the plate or bolt to urge it toward retractcd position so that when the locking; plate or bolt is released, it will automatically move toward retracted position and release the parts.

With the 't'oregoin'g and other objects in view, the invention will-he more fully described hereinafter, and will be more particularl y pointed out in tl'leclaims appended heretoi.

Figs. 1 to i, inclusive. the invention is illustrated as incorporated in a door lock structure, or a lock capable for use in house doors. covers, automobile doors, and in all instances where projecting locking bolts or plates are employed. This form of lock is generally illustrated in the prior patent of Alexander G. Hatch, No. 1,555,969, granted October 6, 1025.

In this first form, the casing 25 is provided with an overhanging marginal flange 26 at the back of the casing forming beneath the flange 26 a groove adapted to slidably receive the opposite edge portions of a sliding plate or bolt 27, which is fitted in the back of the casing 25. The plate 27 is pro vided upon its inner end with a plurality o1 elongations or projections 28 arranged to extend between a corresponding number ot combination wheels 29. and the projections 28 have lateral fingers 30 adapted to extend toward one side of each wheel 29. Each wheel 29 has on said side an annular it o 31 against which the lateral finger 30 is adapted to bear, and said flange 3i is pro vided at one side with a through slot 32 0t suflicient size to freely receive the lateral finger 30 so that said finger may pass from the exterior to the interior of the flange 31 and permit the corresponding sliding move ment of the plate 2?. The fingers 30 are arranged in desired vertical alinement and may be, as shown in the present instance, disposed in the same plane as that of the plate 27. In this arrangement, it is necessary to adjust all. of the number wheels 29 so as to present the slots 32 thereof all in the same plane so that the fingers 30 may all pass through their respective slots simultaneously in order to permit the shitting of the plate 27.

A spring 33 is arranged in any suitable manner upon the lock casing 25, and may be supported upon the flange 26 as shown in Figs. 1 and 3, and may be attached to the flange by a screw 34. engaging through the heel of the spring 33 so as to maintain the spring in position to extend across the back of the plate-27 and against a pin 35 fixed upon the plate 27. The spring 33 bears with suflicient pressure against the pin 35 to move the plate 27 back into the casing 25 when the plate 27 is released. The plate 27 is manually shifted into an outwardly projecting position by a cam or wing 36 which is mounted on the inner end of a spindle 37 journalled in the casing 25 and projecting through an elongated slot 38 which is formed in theplate 27. A stud 39 is carried by the plate 27 against which said cam 36 may operate to project the plate 27 into an outermost position, such as shown in Fig. 1. A stop pin 40 is also mounted on the back of the plate 27 in spaced relation to the pin 39, and spaced radially from the spindle 37 a short distance in order to receivethe opposite portion of the cam Pt) thereagainst to arrest the backward turning of the spindle. The spindle 37 is provided with a hand knob 4L1 upon its outer end. F

which lies against the outer side ot the casing 25 so that access may be readily had to the spindle tor operating the plate 2? wnen released by the combination wheels 29.

In the form of the invention which is illust 'ated in Figs. 5 to 11. inclusive, the improvements are incorporated in an electric switch lock wherein are combined ignition and lighting circuit controlling switches, and by means of this invention such switches may be locked in open and closed positions .in the desired combinations.

In this modified form of the invention the casing 42 may be of cylindrical form to present the desired contour and tor easy fitting in an opening or recess of an instrument board 4: and the casing 42 may be closed at its inner side by a contact housing ll of electric non-conducting material. ikrrangcd wi hin the casing 42 is a block -l:5 suitably recessed to accommodate a plurality of con.- bination wheels i6 of the type which disclosed in our said prior application. Serial #698,718 filed March 12. 1924-. The block 45 carries upon its front face a locking member comprising a sliding belt or plate it? which is relatively broat and provided upon its upper edge with a series of projections 4% with lateral fingers at?) arranged to engage selectively in annular channels 50 tat-1116a in the sides of the combination wheels at. Slots 51. are formed at one point in the set arating annular walls between the channc ls 50 to permit passage of the fingers trom one slot or groove 50 to the other during the shifting of the plate 4.7 on the block 45.

Journalled in the block is a spindle 52 which extends through the front of the easing 42, and is provided with a handle 53 by means of which the spindle 4-2 mav be turned in opposite directions. The spindle is provided with a cam 5% which lies immediately in front of the plate 47, and the rear portion of which, when the plate is in the position indicated in Figure 8, projects downwardly from the spindle 52 asinlicient distance to serve as a stop arm adapted tor engagement with a stop pin carried upon the back of the plate 47 to limit the turning of the cam 54 in a reverse direction. The plate 47 is provided with a lifting stud 56. which lies in the path of the cam 5-1 on the side opposite from the stop so that when the cam 54 is raised by the turning of its spindle 52, the cam 54 strikes the lifting pin 56 and slides the plate 47 upwardly into locking position. The block 45 is provided at one side with a leaf spring 57 the tree endof which extends over the rear side of the plate 17 and against a pin 58, which pro- 'ects from the lower portl-on of the plate,

the spring 57 bearing against the pin 58 plate 47 is snapped downwardly by the leaf spring'57, the stop pin is moved out of the path of the stop on the cam 5% so that the spindle 52 may be freely rotated.

The spindle 52 is carried inwardly through the casing 42 and into the switch housing l i and is there connected to a contact disc 59 provided with contact 60 adapted to traverse fixed contacts 61-carried upon the back of the housing 14. The contacts 61 may be carried through the back of the housing e l for attachment to wires or the like through which the various circuits may be closed.

The contact housing 4 1 is also provided with a contact ring 62 slidably mounted about the plate 59 and independently thereof. The ring 62 carries contact 63 adapted to traverse fixed contacts 64 arranged upon the back of the housing 44 about the contact 61, and which project through the housing 44 as shown in Fig. 7 for engagement with wires or thelike through which current may pass when the various circuits are closed.

The contact ring 62 is shifted back and forth, annularly, by a forwardly projecting lover or handle 65, which extends through the casing 42 and through the front wall thereof, and may be provided uponits forward end with a knob 66 for grasping between the fingers to shift the handle through a short are as determined by the arcuate slot 67 in the front wall of the easing 42. The slot 67 is proportioned so as to give the desired contact combinations by the movement of the lever 65 into the opposite ends and into theintermediate portion of the slot such as indicated in Fig. 5.

The sliding plate 17 is utilized for locking this lever or handle 65 in adjusted position,

and for this purpose the lower end portion of the plate 47 is provided with a. corre- I spondingly formed arcuate slot'67 which is of a width which corresponds substantially to the distance through which the plate 47 is shifted from its opening to its closing position. The plate 47 is provided, in the slot 67, With a pair of projections or lugs 68, which are spaced apart and projecting from the lower edge of the slot 67, at preferably an intermediate portion thereof. The lugs 68 are spaced apart sufliciently to freely receive therebetween the handle 65 so as to hold it from being swung into either end of the slot 67 when the plate 17 is raised as shown in Fig. 8. The plate 47 is thus utilized for locking the lever 65 in a neutral or off position as indicated in Fig. 5, and the lugs 68 may be given any suitable width for locking the lever 65 in either end of-the slot, as desired.

A further modification is shown in Figs. 12, 13 and 14: wherein the device is applied to a door or like closure where the locking plate or bolt 69 projects directly into a keeper 70 or the like as indicated in Fig. 12. The plate 69 is slidably mounted in a casing 71, and has an elongated 'slot 72 formed intermediately therein and from which projects a spindle 73 journaled in the casing, projecting through the front" wall thereof and provided beyond the front wall with a turning knob 74. The inner end of the spindle carries a cam or wing 75 arranged to engage a pin 76 mounted on the plate 69 for sliding the plate outwardly into projecting position when the spindle 73 is turned. The plate 79 is normally urged into retracted position byav leaf spring 77 mounted upon one side of the casing 71, and which bears against a pin 78 projecting from the plate 69 for normally urging the plate to move inwardly. As shown in Fig. 13, the spring 77 is placed under tension by the outward projection of the bolt or plate 69.

The plate 69 is held in projecting position by a series of combination wheels or discs 79, which are mounted in the casing 71 upon a shaft or spindle 80, which is fixed to the plate 69 and shiftable therewith. The

shaft is slidable through the combination wheels 79 and provided with a corresponding series of lugs or projections 81, one for each wheel 7 9, and which is adapted to slide into radial slots or openings 82 formed in the combination wheels 79. The projections 81 are arranged upon the spindle 89 in a pre-determined manner, and the combination wheels 7 9 must be correspondinglyarranged to' dispose their slots 82 in longitudinal or axial register with the projections 81 so that the latter may simultaneously move into the corresponding slots 82. As shown in Fig. 13 in dotted lines, the spindle 80 with its plate 69 is retracted, and the lugs 81 are shown in dotted lines in position within the slots 82 of their respective number'wheels 79. The number wheels 79 are held against longitudinal shifting by the end. walls 83 of the casing 71 so that whenthe spindle 80 with its plate 69 is projected outwardly, and'the number Wheels 79 turned to dispose their slots 82 out of register with the projections 81, the latter, bind against the forward faces of the combination wheels 79 and the plate 69, is thereby held extended.

In the further modified form of the invention, illustrated in Figs. 15, 16 and 17, the cylindrical casing 84 is mounted upon thefront of the switch housing 85 in a manner similar to that disclosed in Figs. 5 to 11, inclusive, and the locking plate 86 is provided upon its upper end with a spindle 87 projecting axially through a series of combination wheels 88 having radial slots 89 therein adapted to register with and receive radial lugs 90 carried by the spindle 87. The plate 86 has a lifting pin 91 upon its face adapted to receive the cam 92 thereagainst when the spindle 93 is turned. A stop pin Set is also carried by the plate 86 to engage the cam 92 when the plate 86 is raised to prevent the spindle 93 from being operated. The pin 9-1 may also be utilized as a pressure pin to receive the end of the spring 95 thereagainst, the spring being mounted on the casing and normally urging the plate 86 into a lowermost releasing position. The plate 86 has an arcuate slot 96 in its lower end to receive the switch lever 97, and the plate has the locking lugs 98 adapted to engage at opposite sides against the lever 97 when the plate is raised for locking the lever 9"! from swinging movement.

As shown in Fig. 17 the spindle 93 may have a knob 99 upon its forward end at the outer side of the casing 84 for the purpose of turning the spindle 93 to not only actuate the plate 86, but to also control the ignition or other circuits in the switch housing 85. As shown in Fig. 15, the lever 97 may have a knob 100 upon its forward end, which traverses the arcuate slot 101 formed in the outer wall of the casing 84 to facilitate the shifting of the handle. The plate 86 is provided with the elongated slot 102 for the reception of the spindle 93 to permit the free movement of the plate without binding on the spindle. The back of the switch housing 85 may have a number of set screws or binding posts 103 to which wires or the like may be attached.

It will be noted that in all forms of this invention the locking-plate or bolt is normally urged into an unlocking position by a spring. Such an arrangement causes the lock to automatically snap into open or re leasing position when the correct combination is set up on the combination wheels. The arrangement also maintains the looking plate or bolt under tension at all times, and prevents the picking or other unauthorized opening of the lock.

The arrangement of the plate with respect to the combination of switches located in the casing and switch housing is also important because the lugs on the plate engage the handle and hold it from swinging movement. This prevents the contact ring from being turned and consequently, different combinations of the fixed and movable contacts cannot be made until the plate is moved to release the lever.

It is obvious that various changes and modifications may be made in the details of construction and design of the above specifically described embodiment of this invention without departing from the spirit thereof, such changes and modifications being restricted only by the scope of the following claims.

hat is claimed is:

1. A look comprising a locking member movable from an effective to an ineffective position, and vice versa, a plurality of permutation tumblers including parts lying in the paths of movement of parts of said locking member and preventing effective movement thereof except when set in a predetermined relation, a manipulator movably mounted in said lock, and having adriving connection with said lockingmember whereby the latter may be moved from one of its two positions to the other when such movement is not obstructed by said tumblers, and a pair of stop elements, one on said manipulator and the other on said locking member, variably positioned by the movements of said part-s, whereby said manipulator is limited in its permissible movement by said stops when said locking member 1s in one of its two positions but is not affected by said stops when said member is in the other of its two positions.

2.
