RELEASING-SLIDE FOR COMBINATION-LOCKS.
Application filed September 15, 191,5.
To all whom it may concern Be it known that l, ROLLIN C. LEWIS, a citizen of the United States, and a resident of Stamford, in the county of Fairfield and State of Connecticut, have invented certain new and useful improvements in `Releasing-Slides for Combination-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 invention relates to an improvement in combination locks, the object being to provide means operable from the outer side of the lock casing for disconnecting and connecting the driving tumbler cen-ter and the tumbler, Awhereby the tumbler center may be disconnected and turned without turning the tumbler, thus changing the combination, and then restored to its normal operative position within the tumbler.
A further object is to provide the lock casing with a tumbler setting sight hole, whereby the movement of the tumblers can be observed, the said sight hole ylia-ving a transparent'cover to exclude dust.
A further object is to provide improved means for attaching the knob spindle to the dial knob `and ring, so that it may be usecl on doors of various thicknesses, .within certain limits, without changing any of ,the parts.
lin the accompanying drawings, Figure l is a view in elevation `of a lock embodying my invention showing the tumbler shifting slide in its normal position; Fig. 2 is a similar view showing the slide in its shiftedposition; Fig. 3 is a view in section of the lock and dial, the slide being in the position shown in Fig. 1; Fig. l is a similar view with the slide in the position shown in Fig. 2; Fig. 5 is a view of the lock casing show ing the tumbler setting sight hole; Fig. 6 isa view in section through the face plate of the casing showing the transparent cover for the sight hole; Figs. 7, 8 and 9, show the dial spindle and washer, and the method of securing the washer `to .the spindle; Fig. 10 is a view of the driving tumbler and Fig. ll a view of the driving tumbler hub and tumbler center.
l represents the lock casing, 2 .a series of tumblers therein and 3 is thedriving tum- Specfcaton of Letters Patent.

bler or the tumbler to which motion is directly imparted by the dial spindle, and which by its rotation, rotates the other tumblers 2 in the well known mannen The .tumble-rs 2 Vare mounted to rotate on a suitable support within the lock casing, and the driving tumbler 3 is also mounted on said support and is provided with a central .section 5 having a h ub t, which in the present instance projects vthrough one face of the lock case. The hub #l carries the driving tumbler center 5, which is disl; shape and provided at its periphery with teeth which mesh with ,similarly shaped teeth formed in the margin or wall of the recess in ythe driving tumbler, in which said tumbler een`- ter 5 normally rests, so that when tumbler center is in its normal position and locked to the tumbler 3, the two parts will rotate together and rotate ,the ,other tumbler-s 2 in the well known manner. This hub 4 `and the tumbler center 5 carried thereby` are free to vbe moved lengthwise the hub,lsol that when moved in one direction ,the ytumbler center 5 will be disconnected from its tumbler 3, and when moved in the other direction will engage and mesh with the teeth on `said tumbler, so that when lthe ,hub 4; is rotated, the tumbler?) .will -be rotated ,with the same. The hub 4C is -provided with an angular opening through the saine for the .reception of the Aangular spindle 6, and the support carrying the Ltumblers 2 is Aalso made hollow so ,that the said spindle may rest therein, the bore of the support being of greater vdiameter ,than the spindle so that there will not be any ,contact between the parts. Vly this arrangement, `the spindle 6 .may be ot a length to fit any thickness of door within certain limits Vand 4be applied to .the door without any `*cutting or adjusting of the parts.
The ,hub L is provided with a peripheral groove 7, in which the cams S on the slide 9 rest and move. This slide is provided with anelongated opening 10, which is enllarged at one end to permit the Ihub 4 to be passed through the same, and is narrowed at itsother end, the side walls of the narrowed part being cam shaped, or inclined, sothat when the saidslide 9 is pulled downwardly the cams thereon, acting against the shoulders or wall of the groove in the hub, shifts the latter en dwise and withdraws the tumbler center 5 from its tumbler 3, thus leavingA the center free to be turned by the dial knob without turning the tumbler, and when the slide is shifted to its other position, it forces the tumbler center into its seat in the tumbler thus locking the two parts together. This slide 9 is slotted as at 11 to receive the post 12 which assists in guiding the latter and the end of the slide projects through the lock case and is preferably bent as at 13 to permit it to be readily grasped and operated from the outside of the lock case.
The spindle 6 is provided near its outer end with a circular groove 111L in which the washer 14 is slipped and partly turned, after which it is permanently secured on the spindle, by upsetting the metal of the spindle in one or more of the corners of the square hole in the washer. This washer rests against the rear face of the dial ring 15 Yand the spindle is locked to the dial ring by the knob shank 16, which bears against the front face of the dial ring, and by the screw 17, screwed into the end of the spindle with its head overlapping the outer end of the shank. The dial 18 is carried by the shank 1G and is secured thereto by the dial knob 19 screwed onto the shank.
In applying the dial to a door, the screw cap 20 in the end of the knob 19, and the screw 17 in the end of the spindle are removed. This leaves the knob shank and its attached knob and free dial to be removed, from the spindle. The dial ring with the spindle in position therein, is secured to the door by screws 21 after which the knob shank, with its knob and dial thereon, is placed on the end of the spindle and secured by the screw 17 and the latter concealed by screwing on the cap 20. The spindle projects through the door and through the angular hub of driving tumbler and projects more or less, according to the thickness of the door, into the support carrying the tumblers 2.
A sight hole is provided in the lock case so .as to permit the operator to view the movements of the tumblers and fence and is preferably covered by a transparent cover 22, which in the present instance rests on a seat in the leek case and the metal of the latterl spun over the edge of the cover to retain it in position. Other means of securing it in position may however be substituted.
In order to change the combination of the lock, the safe, vault, or other door is opened thus giving access to the lock ease 1, at the rear of the door. rll`he slide 9 is then pulled downwardly during which movement the cams S on. the slide moves the tumbler center out of engagement with the driving tumbler, thus leaving former Jfree to turn without rotating the latter, and in condition for changing the combination, which is accomplished by turning the dial to bring the dcsired number on the dial in line with the setting mark, and pushing up the slide which latter movement forces the driving tumbler center into engagement with the driving tumbler. During this operation, the operator may view the movement of the tumbler and fence through the sight hole in the lock case.
It is evident that many slight changes might be resorted to in the relative arrangement of parts shown and described without departing from the spirit and scope of my invention. Hence I would have it understood that I do not wish to confine myself to the exact construction and arrangement of parts shown and described but Having fully described my invention what I claim as new and desire to secure by Letters-Patent, is
