Application filed January 24, 1916. Serial No. 73,941.
locks and more particularly to those of the` permutation or combination type, the object ,of the invention being'to provide an extremely simple and inexpensive arrangement of parts which will be applicable to a wide range of uses and which will be highly eflicient and durable regardless of the exact use to which it is put.
With this general object in View, the invention resides in certain novel features of construction and in unique combinations of parts to be hereinafter fully described andclaimed, the descriptive matter being supplemented by the accompanying drawings which constitute a part of this application and in which:
Figure l is a central vertical section through my improved lock mechanism showing the same in operative position;
Fig. 2 is a vertical transverse section taken on the plane indicated by the line 2 2 of Fig. 1;
Fig. 3 is a view similar to Fig. 1 showing the parts of the device in released position;
Fig. 4 is a vertical transverse section taken on the plane indicated by the line 4 4 of Fig. 3;
Fig. 5 is a third vertical transverse section taken on the plane of the line 5 5 of Fig. 1;
Figs. 6, 7, 8 and 9 are perspective details of certain parts of the device to be hereinafter fully described.
In these drawings, a member lis shown whichmay be the usual spindle of a door lock, the shank of a key, the stem for operating an electric switch, or any otherA device adapted to .be turned onlyv by ,authorized persons. The member 1 is provlded with a head 2 having a flat outer end 3 disposed at right angles to the axis of said head and member, the former having therein an axial socket 4 and one or more notches 5 shown in the present embodiment of the invention as opening through the end 3. Although in most cases the head 2 will be preferably made an integral part of the member 1, it will be readily understood that the head in question might well be formed as a separate part and secured to said mem- L ber. For the purpose of turning the head 2 1n the necessary manner, the arrangement of parts now to be lspecifically described by reference to the drawings, is employed.
The numeral 6 designates a disk or the like toxbe secured in any preferred manner to the,v casing of the mechanism to be operated by the member 1, or to any other approprlate fixed member, it being only necessary that said disk be held against movement. The front side of the disk 6 is provided with a sleeve 7 preferably cast integrally therewith, the axis of said sleeve being alined with the axis of the head 2 as yclearly shown. VMounted for rotation in the sleeve 7 and projecting forwardly therefrom an appropriate distance, is a tubular shaft 8 whose rear end is shown, as yprovided with a head 9 having a flatrrear end disposed either in contact with or in close proximity to the vface 3 of the head 1, said end of the head' 9 having formed Vtherein one or more Vradial notches .'10, two of these notches being here shown.
Mounted yfor rotation and axial shifting in theotubular shaft 8,v is a spindlel11 having an appropriate knob 12 on its outer end, while its inner end is equipped with laterally extending projections 13 preferably in the form of pins. These projections l are adaptedto -be received in the notches jdesignatedat 5, and said shaft is then locked vagainst`rotationj. lAs one simple lmeans of locking the shaft 8 vagainst rotation, the drawings illustrate the construction now to be described.
The sleeve 7 is formed with an aperture n in the periphery of the tubular shaft 8', said cavity having two of its sides designed to form cam surfaces 16 adapted` for a purpose to be set forth. Carried within the aperture 1-'l and extending beyond the periphery of: ,the sleevev 7 when the deviceis not in operative position, is a weighted tumbler 17 here shown in the formof a kmetal cylinder, said tumbler being adapted to drop into the cavity 1.5 when the shaftl 8 is turned to the. properextent, thereby locking said shaft against further movement, provided said tumbler be held against shifting outwardly.
For the last named purpose, a plurality of tumbler retaining rings are shown in the drawings, two of these 'rings being desigi nated at 18,.while a third is indicated by the numeral 19. All of these rings rotatably surround the fixed sleeve 7 and are frictionally held thereon. `Each one ofthe threerings is formed with an internal notch 20, all of said notches being adapted for alinement and for registration with the aperture 1a as shown in Figs.' 3 and l, whereupon rotation of the shaft S willl befperinitted, since one or the other of the cam surfaces 16 will move the tumbler 17 from the cavity4 The Vring 19 isi-of greater diameter thanl the others, said ring beingprovided with a laterally extending .annular Hange 21 which surrounds said other rings, the free edge of said flange abuttinga circular plate` which formswith said flange a protec@ tive housing for the tumbler 17 and the smaller rings `cooperating therewith. The plate 22 is formed with a central opening throughwhich the front end of the tubular shaft S' passes, said end being provided with a collar23 permanently secured` t'hereon in any suitable manner, Aand bearing against the plate 24 to prevent removal of the latterand of parts in rear thereof.
For the purpose of operating the rings 1S by actuation of the plate 22, a rigid pin `26 extends. from -the ring 19 througrhlany desired one of a series of openings'26 in said plate, said pin cooperating with external shoulders 27 on the aforesaid rings 18. The projecting front end of the pin 19valso passes through an opening 26 in aplate 24 mounted on the shaft 8 and capable of being turned thereon to adjust a pointer 24; with which it'isprovided, before said pin is inserted into said opening 26". the plate 22 is rotated until the pointer 211! extends opposite the correct graduation, the notch 20 of one ring 18 will be disposed above the tumbler 17. Rotation of said plate "apredetermined eXtent in the oppo-r site direction, will now properly position the other ring 18while again reversing its direction of movement and turning said plate rto the necessary amount, will position the notch20. ofthe ring 19 intalinement with the others.l The knob 12-may then ybe turned and forced inwardly v unt-il the When' pins 13 are received in thenotches.5 ,wherer upon the member 1 may be operated as above set forth..
outwardly and at the same time turned. to again dispose the pins 13 in the.. notches 10 TWhen the l improved mechanismV is, to,I bel locked, or in other words is -to prevent move.-y inent of the memberihthe knob 12 is pulled whereupon further rotation. of. said .knob
will move the shaft 8, therebydisposinglthe aforesaid notches out ofalinement with .the
notches and allowing .the tumblerlSto drop into the cavity 15.4 Proper actuation [eef of the plate 22 .will now so `dispose the rings' l i 18 and 19 as. to prevent removahof said f tumbler from the aforesaid .cavity untila legitimate user again voperates the.. device..
Preferably, though ynot necessarily ...used in conpmction with thenumerousnoVel featuresabove described, is a centrally. apertured cap 28, which is passed over the head.V and threaded Vinto an annular flange. or`
the like 29 formed on the rear face ofthe.
disk 6. This detail will lretain the head in question inproper relation tothe remainder..
of the device, but obviously -its exact struc-.
ture might vary in a number o f ways..
From. the foregoing description, taken in.
connection with the accompanying drawings, theconstruction, manner of operation, `and advantagesof the yimproved device will be readily `understood withouty requiring a more extended explanation. .In conclusion,
# will state that although certain specific details have been shown and described for illustrative purposes, numerous changes may be made within thescope` ofthe invention as claimed without sacrificing the primary advantagesthereof. y
