COMBINATION-LOCK.

SPECIFICATION forming part of Letters Patent No. 684,082, dated October 8, 1901.

Application iiled May 20, 1901. Serial No. 61,082. (No model.) l

To @ZZ whom it may concern:

Be it known that we, WILLIAM EDWARD HOLMES MORSE and OLIVERHAMMOND BEMIs, citizens of the United States, and residents of Algona, in the county of Kossuth and State of Iowa, have invented a new and Improved Combination-Lock, of which the following is a full, clear, and exact description.

Theinvention relates to combination-locks such as shown and described in Letters Patent of the United States No. 662,285, granted to us November 20, 1900.

The object of the present invention is to provide a new and :improved combination door-lock arranged to permit the owner to readily set the outside knob to a desired combination to prevent unauthorized persons from opening the door, to permit of rendering the combination device inedective whenever it is desired to use the door-lock the same as an ordinary door-lock, and to allow of using the device for sounding an electric alarm on the door-bell.

The invention consists of novel features and parts and combinations of the same, as will be fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is a cross-section of the improvement as applied. Fig. 2 is a sectional rear elevation of the same on the line 2 2 in Fig.

V1. Fig. 3 is an enlarged face view of the outis provided with a knob D and the outer spindie-section is mounted to turn and to slide transversely in a hub E, projecting from a casing E', attached to or forming part of an mechanism can bring the knob into such' position that it can be pushed transversely to engage the inner end of the outer spindlesection C with the spindle-section C to turn lthe latter, and thereby unlock the lock and open the door. For the purpose mentioned the adjacent ends of the spindle-sections O C are provided with a groove C2 and a tongue C3, respectively, normally out of engagement, but moved into engagement when the spindle-section O is moved transversely in an inward direction, as above explained. The

grooved end of the spindle-section O is provided with a pin C4, adapted to abut against the face of the door and prevent the spindle-section C from. being drawn out of position in the door-lock, and a similar pin C5 is on the inner end of the spindle-section C to limit the outward-sliding movement of said spindle section by the pin abutting against the inner face of the easing E. The

pin C5 has its upper portion pressed on opposite sides by the free ends of arms C, fulcrumed in the casing E and pressed on by springs O7, so as to hold the free ends of the y, A

arms O6 in engagement with the pin C5, as shown in Figs. l and 2. The spring-pressed arms C hold the knob F in a normal position; f

but said arms allow a transverse sliding of the pin O5 and the spindle-section C' for the purpose previously mentioned. The lower portion of the pin O5 is adapted to be engaged by a slide CS, mounted to move up and down in the casing E to hold the tongue O3 in engagement with the groove C2 at the time the spindle-section O is in an innermost position. The slide OS is providedwith a button C9, extending through an elongated slot E3 to the outside of the casing E', so that when the section C is in an innermost position and the operator pushes the` button C9 `the tension of the spring G2.

upward, then the slide C8 moves in front of the lower end of the pin C5, so that the spindle section C' is prevented from outward movement. When the several parts are in this position, the door can be opened by turning either of the knobs D or F the same as in ordinary door-locks.

On the outer end of the hub E isformed an annular liange E4, extending part way into an annular groove F', formed on the back of the knob F, and. said annular flange ELl normally abuis against the rear face of a plurality of slides G, mounted to move in radial grooves F2, formed on the face of the knob F. (See Figs. 3 and 4.) Each of the slides G is formed on its rear face with a groove G', adapted to register with the flange E4 when the slide is moved into proper position, andwhen all the slides G are in regsteringpost tion then the knob F, with the spindle-section C', can be moved inward to bring the tongue C3 in engagement with the groove C2 to connect the spindle-sections with each other and allow the operator on turning the knob F to unlock the lock B, and thereby permit of opening the door. As stated, the slides G are, with their grooves G', normally out of register with the flange E4, so that the knob F cannot be moved in an inward direction until the slides G are moved by the operator to bring their notches G' in register with the flange E, and in order to accomplish this the following device is provided: Each slide G is pressed into an innermost position by a spring G2; but the inward movement of the slide is limited by a locktooth G3 on the slide and engaging a pin II, adapted to be set by the operator in one of a row of apertures Il', extending in the direction of the corresponding guideway or groove F2 in the knob F, as indicated in Figs. 3 and 4. On the top of each slide are formed parallel ratchet-tooth racks GL1 G5, of which the rack G4 is adapted to be engaged by a springpawl I, fulcrumed atI' on the face of the knob F, as is plainly illustrated in Fig. 3. Each pawl I is formed at its outer end with an elongated slot I2, engaged by a pin J', secured to a button J, mounted to slide in a radial guideway F3, formed in the knob F, and the inner end ot' each button J is pressed on by a spring J2, so as to hold said button normally in an outermost position. When the operator presses the button J in an inward direction, then the pin J' imparts a swingingV motion to the pawl I, so' that the latter imparts an outward sliding movement to the rack GA1 and the slide on which the rack is secured, the slide G moving outward against When the operator releases the pressure on the button J, then the spring J2 returns the button J, the pin J', and the pawl I to their former positions, it being understood that the arrangement is such that on inward pressure of the button J the pawl I moves the slide forward a distance.corresponding to the length of a tooth on the rack G4. The other rack G5 is engaged by a spring-dog K, secured to the face oi' the knob F, so that when the operator has pressed the button J inward and moved the slide outward, as described, then the dog K engages a tooth on the rack G5 and holds the slide against return movement when the pressure on the button J is released. When the operator presses the button a second time, the above-described operation is repeated-that is, the slide G is again moved outward and locked in an outermost position against return movement by the dog K. Vhen the several slides G are in their normal positions, the grooves G' are out of register with the ange E", the spindle-section C' is held in the outermost position, (shown in Figs. l and 4,) and the iiange E4 abuts against the rear faces of the slides, and consequently the spindlesections are out of engagement.

In order to move the slides the desired distance to bring the grooves G' intoregister with the ange E", the operator successively presses and releases the buttons J the desired number of times to bring the slides G into such outermost position that their grooves G' register with the iiange E4. It is understood that by the use of the pins II and teeth G3 each slide can be set in such a position that a notch or groove G' of the slideis a diderent distance away from the iiange E4 than the.

other slides, and consequently the buttons J have to be pressed and released a different number of times, so as to bring the several slides into proper position. "When this has been done, the operator can move the knob F inward to engage the spindle-section C' with the spindle-section C and turn the latter on turning the knob F to unlock the lock B and permit of opening the door.

In order to reset the several slides G, the following device is provided: Under the spring-pawls I and the spring-dogs K extend the outer ends of levers L L', fulcrumed on the knob F and adapted to be engaged at their inner forward ends by an annular flange N' on a button N, mounted to slide on a post F5, forming part of the knob F. When the button N is pressed in an inward direction, a swinging motion is given to the several sets of levers L L', so that their forward ends lift the pawls I and the dogs K out of engagement with the racks G4 G5, whereby the latter are immediately pushed inward against their pins II by the action of the springs G2. The hub of the button N is provided with a slot N2, engaged by a pin N3, secured on the post F5 to allow the said button N to slide on the post, but to prevent it from turning thereon. On the annular iiange N' of the button N is securedor formed a contact-arm O, adapted to make contact with a contact-screw O', held on an insulated block O2, secured to the knob F, as is plainly shown in Figs. 3 and 4. An insulated wire O3 leads from the contact-screw O' through a bore F6 in the knob F and the spindle-section C' to connect with IIO IZO

a battery Pand an alarm doorbell Q, the return-wire O4 being connected with the casing E' or other metallic part of the lock, making electric connection with the knob F, button N, and contact-arm O. When the button N is pressed for releasing the slides G, as previously explained, then at the same time the contact-arm O moves in contact with the contact-screw O', so as to close the circuit for the alarm door-bell and sound the latter. Thus the lock can be made use of to ring the doorbell by pressing the button N. By having the pin N3 engaging the slot N2 the contactarm O is always held in proper position rclatively to theV contact-screw O to make contact when the button N is pressed. 1tis understood that the button N is held normally in an outermost position by the levers L L. (See Fig. 4.) The knob F is provided with a suitable cover or hood F7, through which extends the shank of the button N, the cover serving to protect the working parts ofthe knob from dust., moisture, &c.

Having thus fully described our invention, we claim as new and desire to secure by Letters Patent- 1. A door-lock having a divided spindle, the inner section of which engages the doorlock mechanism and the outer section of which is mounted to slide transversely and is adapted to be moved in engagement with the inner section, to work the door-lock mechanism for opening the door from the outside, a pin on the outer spindle-section, and a slide under the control of the operator and adapted to move to the rear of said pin, to hold the outer spindle-section in engagement with the inner spindle-section, as set forth.

`2. A door-lock having a spindle made in sections, one of which engages the door-lock 4o mechanism and the other4 is adapted to be moved in engagement with the first section, an escutcheon-hub in which the slidable spindle-section is mounted to turn and to slide, a

-knob onsaid slidable spindle-section, spring- 45 pressed slides mounted to movevin guideways on said knob and having grooves adapted to register with said hub, each slide having a number of parallel ratchet tooth racks', a spring-pressed pawl for engaging one of the 5o racks of a slide, a button under the control of the operator, for imparting a swinging motion to said pawl, a spring-dog for engaging the other rack of a slide, levers extending under said pawl and dog, an electric circuit hav- 5 5 ing a fixed contact on said knob, a contact on said button and normally out of engagement with the first-named contact, a doorbell in said circuit, and a button under the control'of the operator and adapted to be 6o moved in engagement with said levers, to impart a swinging motion thereto and release said pawls and dogs from said racks, to allow the slides to return by the action of their springs, said'button also moving its contact 65 in engagement with the other contact, to close the circuit and sound the door-bell, as set forth.
