Application led November 14, 1924, Serial No. 749,923. Renewed January 7, 1926.

To LZZ whom it 'may concern:

Be it known that I, MEADE VILDRICK, a citizen of the United AStates of America, residing at Honolulu, Territory of Hawaii, 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. f y

This invention relates to keyless locks and has for one of its objects to provide a lock of this character which will be simple in construction, comparatively inexpensive to manufacture and which willreadily lend itself to numerous applications, such for example, as automobile locks ofA various characters, baggage locks, safe locks, builders hardware and in fact,fany form of lock where permutation discs may be employed.

The invention relates in general to the type of lock shown in my prior Patent No. 1,373,283, granted March 29, 1921; in the prior patent granted to Alexander G. Hatch, October 6, 1925, No. 1,555,969; in the prior patent granted to Meade Vildrick & Alexander G. Hatch, No. 1,565,132, December 8, 1925; in the application of Meade Wildrick, entitled Vheel for keyless locks, filed October 17, 1924, Serial No. 746,178; and in the application of Meade VVildrick & Alexander Gr. Hatch, entitled Keyless lock, filed September 24, 1924, Serial No. 739,665.

lVith the above and other objects in view which will appear as the description proceeds, the invention consists in the novel details of construction andcombinations and arrangements of parts more fully hereinafter described and particularly pointed out in the appended claims.

Referring to the accompanying drawings,

forming a part of this specification, in which like reference characters designate like parts r in all the views.

Figure 1 is a front elevational view of a simple bolt lock employing the present invention.

Figure 2 is a vertical sectional view through the lock shown in Figure 1, taken approximately on the plane indicated by the line l2--2 in said Figure.

lthrough the said padlock, taken approximately on the plane indicated by the line 7--7 of Figure 6.

Figure 8 is a horizontal sectional view taken approximately on the plane indicated by the line 8--8 of Fig. 6, 'andV of the bolt employed in'this vform of the invention.

Referring more particularly to Figures .l

to inclusive, .the numeral 10` indicates generally the lock casing or housing which preferably takes the form of ay casting recessed as indicated at 11 to accommodate the permutation wheels as will be clear from Figures 2 and 3.l .A shaft 12 is mounted on the said casing 10 and extends through the recess 11 and has rotatably mounted upon 70 Figure-9-is an enlarged perspective view it a plurality of permutation wheels 13.V

The front face of the casing is closed by the plate 14 secured "thereto in any suitable manner, as by the screws 15, and the said plate is provided with a plurality of openings 16 through which portions of the wheels 13 may project whereby the said wheels may be manipulated in the usual well known manner.

f As best shown in Figures 3 vand 4, the wheels 13 comprise the large discs 17, the peripheries of which bear suitable indicating characters 18 and the said discs are provided with reduced axially extending hubs 19 which in turn are provided with raised annular flanges 20, spaced longitudinally from the body portion 17 and from the ends 21 of the said hubs. Inasmuch as the discs areassembled in Close axial alignment as shown in Figure 3, this construction provides a pair of s aced annular grooves 24 and 25 foreach Wneel which are adapted to accommodate projections carried by the locking bolt, as will appear more iully beloW.

The circumference of the hub 19 which forms the bottom of the groove 25 is preferably provided with a plurality of longitudinally extendingnotches which are adapted to be engaged by portions et detent springs 27 whereby the wheels may be retained in any desired set positions as'will be readily understood.

A 'locking bolt 30 is' slidably inounted'in the v. recess 3.1l provided` in thev casing and the said bolt carries a plurality ot' downwardlyv extending pins or projections `32 which arel adapted to extend into the annular grooves :2liand 25 above described and as is clearly illust-rated infiigures 2 and The annular iianges 20 provided onw the hubs 19 Aare eachcut away vas indicatedat 33 to provide a passageway whereby the projections.32 maybe moved from one side to the other of the fianges 2O as will be readily understood.

in order to .slide the bolt 30, the lat-ter is provided withan elongated slot 35 through which passes the transverse shaft 36, one end ofr which may carry a knob 37, j the other end of which is provided with, a collar 38 retained thereon by means eta set screw 39,. Said shatt36'has rigidly secured to, itj adjacent one tace ofthe boltl 30,. a collar Ll0 rwhich is provided with aradial slot 41, adaptedto receive a pinjor projection 42 rigidly carried bythe bolt 30. It thus results that when theshaft 36 is oscillated by` means oiv the knob- 37, the bolt-3,0 Will be reciprocated longitudinally through the pin. and slot connection, as will be readily understood. A coiled'spring 43 maybe seated ina recess 44 provided in the end of the bolt to move the`.latter in one f direction (see Figure 3).

Coming now to .the form ofthe invention shown, in Figures 6 to 9 inclusive, wherein there 1s shown a padlock embodying the vprinciples of the invention, the numeral 5.0

indicates the inner housing. which; carries thepermutation Wheels `13, which in this instance, are rotatably mounted on a hollow shaft or sleeve 51 mounted in the said housing. The openlower iaceotthis housing is closed by means ot .a plate 52, having openings 53 through whiclhportions ot the said wheels project, whereby they may be manipulated.y rllhe said inner housing is encased in an outer casing Stand carriesthe bolt 55, which boltis providedwith .extensions .or projections 56 tor coactingwith the wheels 13 in the manner above disclosed in connection with Figures 1 to 5;

At the right hand side ot the lock as viewed'in .Figure 6, a recess. 57 is provided between the inner and outer casings, which is adapted to receive the shackle Amember Leaesa 58 having the offset portion 59, the upper edge 60 oi which is adapted to Contact with the Asurt'ace 61, iviththe outer. casing 5ft to act as a stop for limiting the outward movement or" theV shackle. The shackle is indicated at 62 and is pivotally.v connectedxasat G3, to the. member 5.8'as.willbereadily understoodifroinEigure 6. The; other end ot the shackle is provided with a toe 6d which is received in a slot'65 provided in the bolt 55, and said toe engages a lug 66, also carriedby the saidbolt, to lock the shackle will be readily understood from thedrawings.

The bolt, 55 is normally urged Atoward .the lett orilocked position as viewed in Figure 6k by., the coil spring 67 lwhich is received lin the .recess `66v termed` in thebolt and the. oitset Vend. oi thebolt'is. proyided with aprojpection 69 which is adapted to .be engaged byone end'oi a plunger member 7 O which is mounted in a bore 71v4 formed in the outer casing or housing 5a.' The said plunger 70 is provided with a projection 72 which tends through the side wall of the casing ll where .it may be. pressed bythe thumb or finger anda coil spring 7f3 is co-operatively associated `with thel said vplunger 7 Ol to nermally urgeit outward to the position shown in Figure 6.-

In assembling the lock, .the wheels 13l are first introduced into Vthe inner housing 50 in axial.; alinement, lwhereupon the sleeve lwis introducedV from the lett of ythe said .housing as. viewed'in Figure 6,I through the bores of the wheels-the shackle parts are next properly positioned ywithin the outer housing, pwhereupongthe inner housing1 is introduced .into the. outer housing and the pin 7 5 passed throughlthe bore of the sleeve 51 and threaded into the lefthand- Wall ot the casing: 5,41. During this` operation of course, the shackle 62j and-its; associated parts are maintained inthe dotted linseposition, shown in .Figure 6 so thatthe lpin 75 may be introduced through the aperture 76',- providedv in the outer'housing. However, when the shackle is movedl te locked vor full-lined position, the extension 59 of rthe shackle 5S will ymove down over the right handend ot the pin thereby preventing its accidental or intentional withdrawal.

`While the annular flanges 20 ot-the wheel 13 in both forms otthe present`V invention have been shown as plain, it will be obvious that it desired, they may be provided` with false recessesor slots, similar te those shewn in my co-pending applications Serial No. 746,178, fil'edjOctoberf27th, ,192lfand Serial No. 747,777siiledNevemberllf, 1924. lt'is also obvious that any or all of the various features described yand-claimed in the other co-pending` applications above mentioned, may. be incorporated. in the present invention, without a radical change' and there'- fore it is not wished to be limited to the above disclosure except as 'may be required by the following claims.
