SPECIFICATION forming part of Letters Patent No. 473,786, dated April 26, 1892.

' Application filed October 16, 1891. Serial No. 408,929. (No model.)

To @ZZ whom, t may concern/.

Be it known that I, LEOPOLD E. SCHNEIDER, a citizen of the United States, residing at Galena, in the county of Jo Daviess and State of Illinois, have invented certain new and useful Improvements in Permutation Door-Locks, of which the following is a specification, reference being had therein to the accompanying drawings.

The object of myinvention is to provide a permutation or combination lock adapted for use especially upon house-doors, the roomdoors of hotels, dac.

lVith this object in view myinvention consists in the lock having its parts constructed and combined as hereinafter specified.

In the drawings, Figure l is a perspective View of my lock. Fig. 2 is a plan View with one of the side plates of the case and parts attached thereto removed. Fig. 3 is a section on theline of Fig. l. e is a horizontal section on the line g/ yof Fig. 2. V Fig. 5 is a perspective view of some of the parts removed from the case, and Figs. 6 and 7 are.

detail views of the bell or alarm-ringing device.

The lock, as shown, is designed to be secured to the inner face of the door, and its casing A maybe of any suitable construction. At or near its vertical center is the latch-bolt B, projected normally outward by a spring l) and having, as usual, a beveled face b to en able it to be cammed inward when forced against the usual keeper. At its inner end said latch-bolt is expanded in width, where is provided a substantially rectangular slot or recess b2, one of Whose end walls is adapted to be engaged by either of two oppositely-extending arms c c on a knob-spindle C, Whereby the bolt may be moved against the stress of the spring b to disengage the bolt from the keeper. The knob-spindle C does not pass through the lock out both sides, but projects on one side only into the room on Whose door the lock is placed and is the one designed to enable the operation of the lock frornthe inside. The two `arms c c are provided to enable the latch to be shifted whichever may be the direction the knob may be turned, and preferably the wall engaged by said arms is a convex surface. The latch-bolt may at all times be shifted from within the compartment by simply turning the knob-spindle C. AlA second knob-spindle D projects from within the lock outwardly and is designed for use on the outside. This spindle D is in the same horizontal plane, but. not in a line axially with the inner spindle C, and adapted to be operated by it is the series of circular tumblers or disks E, F, G, and H, four in number, and provided each with a radial slot. The first-named E has a cylindrical hub e, upon which the others are placed, and is actuated directly by the spindle D for this purpose, being at the end of the hub away from the disk provided with an angular cavity e', with Which a similar angular formation d on the knob-spindle can engage. The disks F and G are journaled loosely upon the hub e, so as to be capagble of rotation thereon i11- dependently of each other and so that there may be an independent rotation of the disk E. The disk H, which is the outer one of the series, is fixed upon the disk-hub c, so as to rotate only when the same is rotated by means of a short radial pin e2, engaging a notch h in the disk. The otherdisks E, F, and G are the lock-tumblers proper, While the disk II has a special function, which Will be here inafter referred to.

In the face of the disk E adjacent to the disk F is an annular cavity e?, in Whose bottom is an annular series of holes, in any one of which may be placed a pin or screw e4, and a similar annular cavity f is provided in each face ot' the disk F, and one g in the face of the disk G, next the disk F. In each of these cavities are provided pins or screws adapted to be placed in certain positions relative to the radial slots in the tumblers to effect, by engagement with each other in the well-known way, the placing of the slots in alignment with each other, and a rcciprocable piece or stump connected with the sliding bolt or latch, Whereby the latter is enabled to be actuated.

Journaled axially in line with the spindle D is a sleeve I, the journaling means being at one end the lock-casing side or Wall and at the other an annular cavity in the end of the hub e of the tumbler E, into which a reduced portion of said sleeve extends. The opening fr' in said sleeve is angularin crosssection, conforming to the angular portion d on the spindle D, and is designed to be en- IOO gaged by the latter, which for this purpose is susceptible of a longitudinal movement.

The sleeve I is provided with two diametrically-extending arms z" i', with which the two arms k 7c of a sliding U-shaped piece K are adapted to engage, said arms having inturned or hook-shaped portions for this purpose. The piece K is movable bythe rotation ot the sleeve I when the knob spindle D is turned, and itsmovement' is imparted to the latchbolt by means of an arm 2, attached thereto and extending from it to the'bolt in a line parallel with the knob-spindle. The free end ot the arm t2 engages with one end'ot a slot b3 in the bolt B, and preferably the engaging part is in the form of an under-cut notch 'i3 in the arm. The provision of the two arms t on the sleeve is to enable the latch-bolt to be thrown whether the door-knob be turned one wayor the other.

The tumblers or disks are con-lined in place by means of an arm or extension l of a plate Il, attached to a block or piece M, arranged near one side of the lock. An opening in said arm l journals one end ofthe disk-hub e, while a cylindrical boss or projection on the disk has a bearing in the lock-casing wall. The block M servesY in part to journalor furnish bearing for the spindle @,which passes through the same, and said block is recessed to accommodate the arms c on said spindle and the contiguous portion of the latch-bolt. The periphery of each tumblerA E, F, and G is formed into a series ot' teeth e, convex in shape, between which is a slight space, and for each tumbler is provided a fiat spring N, secured to one end of the block M, which at its free end carries a tooth 0r lug n to engage said teeth. The latter in passing over the l ug fn, Will cause a distinct sound or click and constitutes the means for working the combination, which is done by counting the previously-determined number of clicks upon turning the knob-spindle in theA previously-determined direction. The spring, too, insures that when the tumbler has reached its proper position it will be securely held thereat against accidental movement likely from the friction of the adjacent moving parts.'

To indicate the point at which it is necessary to begin to count the number of clicks or sounds to work the combination,I provide an alarm mechanism operated by the disk 1I hereinbefore described. Said disk has upon its outer face a projecting pin or stud h', adapted when the disk is turned in the proper direction the required degree to engage with and trip an arm o, depending from a rockshaft O, that is journaled in a bracket P,

which is secured to the side wall of the lock-l case and in an opening in the said wall, through which it extends a short distance to the outside of the case. On such outer end the shaftcarries a hammer Q, adapted when the shaftis rocked by the disk Il to be struck against abell S by a coiled spring o', mounted on the shaft O, said spring being placed under tension by the rocking of the shaft. If the disk H be turned reversely to its proper direction, the pin h will engage the face of the arm 0 which is beveled, and cam it and its shaft to one side in the direction of the ylength of the shaft, which latter is made longitudinally movable, and the bell therefore will not be rung. A lug p, depending from the bracket P, serves to limit the movement of the trip-arm after engagement by the pin k on its return under the power of the spring 1 to ring the bell.

The bell is supported from an arm that is suitably secured to and projects from the lock-case.

To enable the lock to be used from the out- ;side without the necessity of operating the g combination device, theinnerendof the knobspindle D is reduced in diameter torform an i annular flange d', which when the spindle is `pushed to the inner limit ot its motion is I adapted to be engaged and held by a vertically-movable baror plate R, held to the outer side of the lock-casing by two screws r r, which pass through elongated slot-s in thev l plate. upper portion 7", circular and o f a diameter to permit the passage of the liange d on the In the latter is an opening having an spindle, and an elongated portion r2, narrower `than the iiange, so that when said plate is moved upward the ange will be engaged by its walls or edges and the spindle locked against longitudinal movement. Vhen the spindle is moved inward, as above stated, itsv .angular portion passes out of engagement with the angular cavity in the disk-hub e and into the angular opening in the sleeve. A suitable knob is attached to the plate It," by which to move it and to hold it against accidental displacement in its lowered position with its circular opening in line with the spindle, and in its raised spindle-locking position it is provided on one of its edges with two depressions adapted eachto be engaged by a flat spring s, attached to the casing-plate.

I provide my device with a bolt or deadlock T, arranged to slide in the case just abovev and parallel with the latch, whiclris adapted to be thrown outward by a thumbpiece t, arranged to connect with the bolt from the top of the lock-case, on the outside thereof, by means of a long screw, whose inner end passes into the bolt. On its rearend the latter has a downwardly-extended arm T, which when the bolt is thrown outward into locking position is adapted to be engaged by the arms c c on the spindle C and moved in- IIO nbell is struck through the trip device operated by the disk H, and then from this as a starting-point the spindle is turned the predetermined number of clicks or sounds and in the proper direction until the several radial slots are in alignment with each other and the arm or stump i2 of the latch-bolt-moving device. When this is accomplished, the spindle is slid inward, so that its angular portion is removed out of the angular portion of the hub of the disk or tumbler E, thereby leaving the tumblers in such position and into the angular openingin the sleeve. Then by turning the spindle either to the right or left the latch-bolt Will be drawn as the arm t2 of the permutation mechanism will pass into the radial slots. To lock said bolt against movement, it is necessary simply to draw the spindle D outward to its former position and turn it sufficiently to destroy the coincidence of the radial slots of the disks.

The combination can be varied as desired simply by shifting the positions ot the pins or screws in the tumblers, all of which, including the bell-ringing disk, being alike capable of being differently located for this end.

My lock is entirely adapted for use on doors particularly, in view of the use of sound as an indicating means, instead of employing a dial, which necessitates light. The door is never locked to one on the inside and it can very readily be arranged so that resort need not be had to the combination to open from the outside.

The bell may be used as a call-bell and will always give notice that the lock is being manipulated.
