KEYLESS LOCK.

Specification of Letters Eatent.

Patented Mar. 29, 1921.

Application led .Tune 2, 1920. Serial No. 385,926.

To all whom it may concern:

Be it known that I, MEADE 1WILDRICK, a citizen of the United States, residing at- Savannah, in the county of Chatham and State of Georgia, have invented certain new and useful Improvements in Keyless Locks; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My present invention relates to improvements in keyless locks, and it is intended to A yprovide a mechanism which may be used in combination with locks of standard construction, or of special design, in which the necessity for a key is done away with.

According to my invention I provide a combination wheel arrangement in connection with. a locking bolt and other details,

whereby the lock may be set atany given combination and can be operated only by a person knowing said combination and understanding the mode of operation of the scribed in the specification.

shown in Fig. 4 as seen from the left of said ligure.

' cured thereto as by means of the bolts a2.

' in the 4frame of the bearing block This housing comprises two chambers, one, the larger chamber, A for the locking bolt and combination wheels, and the smaller chamber A2 for the locking plate carried by the hasp. The housing is transversely slotted, as at a3, to permit the insertion of the said locking plate, and as at a4 to disclose the outer numbers of the combination wheels.

B represents the hasp which is hinged as,

at b to the plate D carried by the plate D, which plates D and D are secured to the receptacle X in any convenient way, as by,

means of the rivets C. The hasp is shown in the closed and locked position in full lines in F ig. 2, and in the open position, in dotted lines in said figure, and it is also shown in the closed and locked positionin dottedlines in Fig. 1.

The means for locking the hasp comprise i the locking plate E, preferably slotted at each end, as at e", and provided with a boss.

e adapted to project into a socket 6 in the hasp. The plate E is connected by means of the stem Vto the handle E2 which has an annular bottom e?. This steml E is rigidly secured tothe locking plate E in any convenient way, as by means o f the nut e', and the connection is such that when the handle E2 is turned the locking plate E will l -also be turned.

F represents the locking bolt which has attached thereto any convenient handle, such as the knurled head f. This locking boltfis provided 'with three axial 'ribs f', f2 and f3, and with a. downwardly projecting locking bar F which includes the vertical legs f4 and f5, with a slot betweenthem, andl the cross piece f6 at the bottom. These ribs f', f2 and f3 slide in grooves g,Gy2 and g3 mounted in the lock casing. The rear fa'ce of this frame is cut away, as at g, to permit ,move- Ilpent of the locking bar F', as `shown in evolubly mounted on the shaft I in the lock casing are a plurality of.:` combination wheels of which I have shown three, H, H andIIZ, but there may be two or more of these combination wheels if desired. 4 I prefer to use three as affording sufficientA protection for all practical purposes without unnecessarily complicating the mechanism,

but two may be used if desired. These combination wheels are all preferably of similar construction, one of which is sho-wn in detail in Figs. l and 5, in which the body of the wheel is provided with a se ental slot ko just inside the radial slot L. Ahe periphery of the wheel is preferably grooved, as at L, and rovided with screwthreaded sockets k2. he segmental strips K are mounted in these grooves, bearing numbers one to nine, as shown in Fig. 5, and these strips are secured in place bycclamp .screws L engaging in the corresponding sockets h2.

In order to vary-the combination, it will be sufficient to move the said screw L and shift the segmental strips K around through adistance sufficient to change the reading of the exposed figures when the slot h registers with the cross piece f6 of the locking bar F A few only of these numbers on each wheel will be exposed in the openings a* of the "lock casing as indicated in Fig. 1. It Awill be noted that when the three wheels H, H and H2 are turned with their radial slots `v indicated in dotted lines in Fig. 2, but if any one of these wheels is turned so that its slot h does not register with the cross piece f6, then it will be impracticable to pull the locking bolt to the front.A It will also be obvious that it would be very difficult, in fact impossible, for all practical purposes for anyone not familiar with the combina, tion to set the three combination wheels so that all three slots h will simultaneously register with the cross piece f6 of the locking bar F.

Assuming the parts to be inthe position shown inv full lines in Fig. 2, in order to release the hasp it will be necessary to see that all three of the wheels have their slots l1. registering with thel cross piece f6. v bolt being in the position shown in full lines, itsrib f will engage in one of the notches @o of the locking plate E carried by the hasp. Now if the bolt be pulled -forward to' the position shown in dotted lines. in Fig. 2, the c'ross piece f6 will pass through the slots k in the rings, and the rib f will move The -clear ofthe notch 4e0 permitting the locking l plate E to be turned by means of the handle E2. l

When thislocking plate/E is turnedY through a right angle from the position shown in Figs. 1 and 2, it will register withthe `transverse slot a3 in the lock casing, k'and the hasp may be swung' clear to the lposition.

be Apointed out.

terasse inside at any time, but can be opened from the outside only when the combination wheels are set at the proper position for permitting the sliding of the locking bolt, as already described in connection with Figs. 1 to 5.

In'the modification shown in Figs. 6 to 10, M represents al suitable metal casing mounted in the door X in any convenientl way,l which casing preferably comprises a housing M and a cover or rear plate M2 secured to said housing in any convenient way, as by means of the screw bolt-s m. The lock- .ing bolt F is similar to that already described with reference t0 Figs. l to 5, exceptthat it may be more convenient for purposes of assembly to fasten the -knurled head f to the main body of the locking bolt by means of a stem Fo and nut f.

In this modification the v combination wheels H, H and H2 are constructed and coact with the locking bolt precisely as already described with reference to Figs. 1 to 5. Slight changes are made, however, in the devlce cont-rolled by the combination lock already described,

N', represents the front knob of a door, carried b v the stem N, the rear end of said stem preferably being provided with a flange or set collar 1t to which the. stub shaft N2 is connected, which stub shaft carries a downwardly projecting plate or rib N3, slotted as at n3 to register with theupper rib f" on the locking bolt F when said loc-k iIng` bolt is pulled forward, as shown in iig. 8. c

In Fig. 7 the locking bolt is shown ,in the position for releasing the front door knob, but in Fig. 8 it is shown in the. position for lockirg the same. There itv is desired to open or close the door from one side only. as with safes, vault doors, or the like. a single knob with stem would sufce.

as ust described; but in order that the door` may be freely opened from within some suitable arrangement should be provided for vshooting the ordinar7 bolt O used in holding the door closed. Such an arrangement is shown in detail in Figs. 6 and Lin which the bolt O is chambered. as. at o.to receive the coil spring O normally tending to push the said bolt outward to the position for holding the'doo1",closed. The spring 0 mounted in the bolt may bear against the guide lug O2 attached to the lock casing. as

at o2. and the outward travel of the saidv mental teeth p on the housing P. carried 'by the stem lP to which the inside door knob P2 is rigidly attached. 'This housing is chambered as at p0 to receive the end of the stub and which will now .inserted in the casing shaft N2 which carries the spring-impressed pawl Q engaging with the ratchet teeth p' on .the inner wall of tle chamber p0, as shown most clearly in Fig. 10. By this arrangement the knob P2 may be used to slide thev bolt O in either direction, irrespective of whether the combination lock is on or not.

In order to operate or open the door from the front, it will be necessary to have the slots h in the various combination wheels so set that the cross piece f6 may be slipped from the position shown inFig. 8 to that' shown in Fig. 7. Yhen the parts are in the position shown in Fig. 7, the door may be opened with equal facility from either the front or the rear; but if the bolt F be in the position shown in Fig. 8, and any one. of the combination wheelsA be turned so that its slot does not register with the travel of the cross piece f6, then it will be impracticable to open the door from the front.

In the arrangement shown in Figs. 11 to In this modification the locking bolt is I shown as built up ofa stem F0, carrying' the knob or' handle f and thesleeve F 2, car-y rying the side ribs #and f3, and the locking bar' F, ksimilar to the. locking bar already described. This sleeve F2 is secured to the stem' F o. by mea-ns of a set screw f7 105 which may be'insierted through the opening 87 in the housing block S, which block is rIhe casing R, may be provided with an internally pro? jecting'rib r, and the block S may be Secured thereto by means of a screw r', see Fig. 111 Thus the casing R and the housing.block.S effectually mask all of the parts, except the shackle T and the exposed portions of the combination ywheels which project into the slots fr provided in the front of the casing R.

. rI`he housing block- S is provided with chamber s to receive the -arm t of the shackle `T. whicl arm is preferably provided with a flange t to prevent it from being withdrawn from the casing R. as shown in,` Fig. 11. The shackle is U-shaped in cross section. and the two legs are providedl on op- -posite sides with the notches t2 and t3 to engage the ribs f'f' and f3 of the locking bolt. when the shackle is in the closed and locked position, as shown in Figs. 11 and 12.

It will be obvious that unless the combination wheels are so setthat their slots k will all register with the cross piece f6,

then the bolt F cannot be pulled forward and the shackle will be held in the locked position. When the combination wheels are so set that its slots h all register with the cross piece f6, then the locking bar F may be pulled forward, causing the ribs f2 and f3 on the locking bolt to release the shackle and permit it to be drawn to the position shown in dotted lines in Fig. 11, and then rotated about itsleg t if desired.

In the modification shown in Figs. 14 to 17, I have shown my invention as applied to locking the various electric circuits of an automobile. U represents the casing, preferably flanged at its front, as at u, and secured to the instrument board, not shown, of the automobile This casing is chambered, as at U9, and the rear end is closed by an insulating` disk U carrying the binding posts V and V connected bysuitable conductors to the source of electricity carried by the vehicle,l not shown.

These binding posts are shown inFig. 16, and one of them only is shown in F igl. 15.

ounted in this casingis an insulating -l bearing block U2 in which the locking bolt F3 is slidably mounted. This locking bolt sible for an expert to turn these wheels, note carries two side ribs f2 and f3 adapted to engage in the teeth L02 and w? on the segments carried by the shafts fw and fw, on' which shafts are fastened theA switch arms W and W', respectively, which make contact-With the contact points for operating the various devices carried by the car; v l have shown in Fig. 17 the two switches W and W in the off position. By turning the switch W to make contact with the point y the circuit is closed through the binding post Y, which may control, for instance, the circuit for the side and rear lights. The binding post Y carries the contact point y which ymay control the auxiliary head and the rear lights; andthe binding post-Y2 may carryI the contact point 'y2 for controlling the head and rear lights.

The switch W may be used to control the circuits through the binding posts Y3 andthe contact g3 from theV battery when the magneto is not in operation, and through the-binding posts Y4 and the contact point y4 when the magneto is on.

The cross piece f6 carries', insulated there-- from, the contact strip `Z, see Figs. 16 and 17, which makes contact from the main binding posts V and V and closes and fprovided with thumb lugs breaks the circuit according to whether the p locking bolt is in the rea-r positionV shown in full lines in Fig. 15, or is moved'more or less forward to break the circuit. i

The switches W and W are preferably or handles W9 -for convenience in operating the same.

It will be obvious that thebolt F3 can-l not be moved forward unless the radial slots l1, of all thel combination wheels register with the cross piece f, and that yif any one of these wheels be turned so'. that its slot will not register with saidv cross piece thelocking'bolt F3 cannot be moved axially.

In the operative position, the locking bolt F 3 is shoved inward,`as shown in Fig. 15, and when in the locked position the said locking bolt is drawn outward until the ends of the ribs f? and f3 engage the rear wall of the front face of the casing7 at which time the cross piece f6 will have been drawn into the segmental slot hf in all three of the combination wheels.

Now if any one of the combination wheels be turned through an angle, the locking bolt will be held in the withdrawn position, and all of the electric circuits will be broken.

The above described contact strip Z may be made independent of the contacts Y, Y2 Y3 and Y4 if desired.

It will be`` noted that in all of the con-A structions hereinbefore described the set screws L roject somewhat and will prevent -the combination wheelsfrom being turned far enough to expose the slots k through.

the corresponding recesses in the front of tliexlock casing, otherwise it might be pos- `If it b e .desired the various combination wheels may have the numbers thereon shown in luminous paint so that the ,combination may be set at night without the use of arti-. l 'icial light.

While I have illustrated the various combination wheels provided with indicia in the form of Roman numerals, it will be obvious that the letters of any language may be substitutedfor the Roman numerals, or, if preferred,- designs or hieroglyphs may be used on the various combination wheels, and

theseJ indicia may be varied from time to time by simply shifting the adjustable strips onthe periphery of any one or more of the various combination wheels.

It will be noted that all ofthe various devices hereinbefore described possess the following elements in common (1) A sliding locking bolt carrying ribs izo locking bar having a transverse cross piece.

(2) A series of combination wheels, each provided with a segmental slot opening into `a radial slot, and that unless all of the wheels are set with the radial slot registering with the cross piece, it will be impossible to operate the device.

(3) Therey is a third device locked'or re- I leased bythe sliding locking bolt, and the movement of the locking bolt is .controlled by the position of the combination wheels aforesaid.

lVhile I have shown the invention as applied to the various purposes hereinbefore' described, it will be obvious that it may be used in a great many other relations which are not herein described; and I do not mean to limit the invention to any specific use.

It will also be obvious that various modiications might be made in the construction,

combination and arrangement of parts which could be used without departing from the spirit of my invention; and I do not mean to limit the invention to such details except as particularly pointed out in the claims.

Having thus described my invention what I claim and desire to secure by Letters Patent of the United States is l.
