To rtl?, whom it may con/007111,.'

Be it known that we, WILLIAM EDWARD HOLMES MORSE and OLIVER HAMMOND BEMIS, citizens of the United States, and residents of Algona, in the county of Kossulh and State of Iowa, have invented a new and Improved Combination Door Lock and Knob, of which the following is a full, clear, and exact description.

'llie object of the invention is to provide a new and improved combination door lock and knob arranged to Work the door-lock by the use ofthe outside knob,which latter is adapted to be set to any desired combination to prevent unauthorized persons from opening the door and to allow the owner to readily unlock and open the door without the use of. a key.

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

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

Figure l is a cross-section of the improvement as applied. Fig. 2 is a sectional front elevation of the same on the line 2 2 in Fig. l, and Fig. 3 is an enlarged sectional plan view of the outside knob, the section being on the line 3 3 in Fig. 5. Fig. is an enlarged cross-section of the same on the line 4 4 in Fig. 5. Fig. 5 is an enlarged face View of the outside knob With the cover therefor removed, and Fig. 6 is a sectional plan view of the same on the line 6 6 in Fig. 5.

In the door A is arranged the usual door lock B, of any approved construction and adapted to be operated by the inner section C of a divided spindle, the outer section O of which is adapted to be locked to the inner section, so that the spindle can be turned from either the outside or the inside to unlock the door. is provided with aknob D, and the outer spindle-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 escutcheon E2, secured to the outside of the door in the usualmanner. On the outer spin- The inner spindle-section O- dlesection Cl is secured or formed a knob F, containing a combination mechanism which normally prevents the knob F and the spindlesection O from being moved inward to en gage the spindle-section C' with the spindle` section O,so that unauthorized persons cannot open the lock upon turning the knob F; but a person knowing the combination lnechauf ism can bring the knob into such position that it can be pushed transversely to engage the inner end of the outer spindle-section C with the spindle-section C to turn the latter, and thereby unlock the lock and open the door. For the purpose mentioned the adjacent ends of the spindle-sections O O are provided with groove and tongue C2 O3, respectively, normally out of engagement, but moved into engagement when the spindle section C' is moved transversely in an inward direction, as above explained.

The grooved end of the spindle-section O is provided with a pin O4, 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 casing E. pin C5 is pressed on opposite sides by the 'free ends of a spring O6, secured in the casing E (see Fig. 2) to hold the spindle-section C and the knob F in a normal position, as shown in Figs. l, 2, and 5,the spring, however, allowing a transverse sliding of the pin C5 and the spindle-section O', for t he purpose previously mentioned.

On the outer end of the hub E is formed an annular flange E3, extending part way into an annulargroove F', formed on the back of the knob F, and the said annular tiangeE3 normally abuts against the rear faces of a plurality of slides G, mounted to move in radial grooves or guideways F2, formed on the face of the knob F. (See Figs. 5 and 6.) Each of the slides G is formed on its rear face with a groove G, adapted to register with the iiange E3 when the slide is moved into propel' position, as 'shown at the left in Fig. 6. When all the slides G are in this position, then the knob F, with the spindle-section C,

can be moved inward to bring the tongue C3 in engagement with the groove C3 to connect the spindle-sections with each other and allow the operator on turning the knob F to unlock the lock B and permit of opening the door. As stated, the slides G, are with their grooves or notches G',normally out of register with the flange E3, so that the knob F cannot be moved in an inward direction until the slides are moved by the operator to bring their notches G' in register with the flange E3, and in order to accomplish this result the following device is provided: Each slide G is pressed into an innermost position by a spring G2, but the inward movement of each slide is limited by a pin H, adapted to be set by the operator in one of a series of apertures H', extending in a radial line from the center of the knob, as indicated in Figs. 5 and 6. 0n the top of each slide are formed parallel ratchet-teeth racks G3 G4, of which the rack G3 is' adapted to be engaged byasp'ring-pawl I, secured on an arm I', fulcrumed at I2 on the face of the knob F, as is plainly illus-- trated in Fig. 5. Each arm I' is pressed 0n at its free end by a spring I3, and said arm is also engaged by a pin J', secured to a button J, mounted to slide in a radial guideway F3,

formed in the knob F, it being understood that `the pin J' engages the arm I' on one side and the free end of the spring I3-engages the arm on the opposite side. Thus the pawl I, with its arm I' and the button J, are normally held under the tension of the spring I3 in the position shown in Fig. 5. When the operator presses the button J in an inward direction, then the pin J'imparts a swinging motion to the arm I' and the pawl I, so that the latter imparts an outward sliding movement to the rack G3 and the 'slide on which the rack is secured, the slide moving outward against the tension -of its spring G3. When the operator releases the pressure on the button J, the spring I3 returns the pawl I, arm I', and button J to their former positions, it being understood that the arrangement is such that at one inward pressure of the button J the pawl I vmoves the slide forward a distance corresponding to the length of a tooth on the rack G3. The other rack G4 is engaged by a springdog K, secured to the face of the knob F, so that when the operator has pressed a button J inward and moved a 'slide outward a distance corresponding to the length ot' a tooth on the rack G3 then the dog K engages a tooth on its rack G4 and holds the slide against ret-urn movement when the pressure on the button J is released. Now when the operator presses the button J a second time the abovedescribed operation vis repeated-that is, the slide G is again moved outward and locked in the outermost position against return movement by the dog K.

Now when the several slides G are in their normal positions the grooves G' are out of register with the flange E3, and the spindlesectionwC' is held in the outermost position It is understood that by the use of the pins Hv each slide can be set in such a position that the notch or groove G' of the slide is a different distance away from the flange E3 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 the 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 upon turning the knob F to unlock the lock B and permit of opening the door.

In order to reseat the several slides G, the following device is provided under the rspring-pawl I and the spring-dog K extend the outer ends of levers L L', fnlcrumed on the kznob 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 F3, 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 G3 G4, so that the latter are immediately pulled inward against their pins H by the action of the springs G3. The knob F is provided with a suitable cover or hood F3, through which extend the buttons J and N, the cover serving to protect the working parts in the knob from dust, moisture, &c.
