To all whom itmwywuncewv:

Be it known that we, JAMES A. MCLAIN and' HARRY A. Brooks, both subjects of the King of Great Britain, residing at Los Alngeles, inI the. county of Los Angeles, State of California, have invented a. certain new and useful Door-Lock; and we do hereby de- Clare thex following to be al full, clear, and exact description of the invention, such as will enable others skilled in the art to-which it appertains to make amd usethe same.

Thisy invention relates to door locks, and has for one` of its objects to provide a simplel and compact construction therefor which shall embody novel advantageous features and be durable and effective in use.

Another object of the invention is to provide a lock which may be installed in a door with. a minimum amount of labor by being fit-tedin openings easily made by an auger, and inwhichthe key hole,l by being placed in the knob on the 'o111`tside,. can be easily Still another object is to; provide' a. setmechanism: for the lock which. can be readily operated' to permit withdrawal of the bolt by the turning of either the inside knob or the outside knob, or to permit withdrawal of theI bolt by turning the outside knob: after a suitable key has been inserted in the lock, or to permit locking'the bolt against4 withdrawal by manipulation, of either the inside knob'- or the outside knob key has beeninserted in` the lock.

@ther objects and the advantages of the invention will be apparent to: those skilled in` the art, from: a consideration of the following, description of one form of construc tion which embodies it, taken in connection with. the aecompanying. drawings, in which- Figure 1 is a horizontal central section through the lock fittedina door;l Fig'. 2 is a section on line 2-2 of Fig. 1; Fig. 8' is a perspective detail of a part of the deadlock mechanism and bolt; Fig. 4 is an elevational fragmentarydetail of the bolt-withdrawing mechanism; Fig. 5 is an elevationL of a portion of the edge of the door showing end of bolt and guide-plate; Fig. 6 is a. section through the inside knob with contained parts in elevation, and Fig. 7 is a detail of the dog.

A s shown, the lock may be tted in the stile 2 of the door, having therein circular intersecting holes 3' and 4', which latter may be made with an ordinary auger of suitable diameter, Hole 8 may have a lining 5 and 1n the inner end thereof a spring 6 bearing aga-inst the head 7 of bolt 8, which latter has its4 outer end disposed in guide-plate 9 and 1s provided with a slot 10 nea-r its head 7 In hole 4 is disposed a tube 11 passing through slot 10 of bolt 8 and having arranged therein a rod 12. The hollow outside knob 13, preferably of chilled steel, has aixed thereto sleeve 14, which extends over tube 11 and nearits inner end is secured by screw 15, which latter, when the parts of the lock are assembled, is concealed and out of reach from the outside in consequence of the end pf the sleeve being tted in a bushing 16 disposed in the outside end of opening 4, as will readilyv appear from Fig. 1 of the drawings.

In knob 13 is arranged any suitable mechanism 52', operable by' a suitable key 5310 move rod' 12 to the right, -for a purpose hereinafter mentioned. As shown the mechanism 52 may consist of a part 54 integral with sleeve 14 and provided with a recess in which, as in a common type of lock, is disposed therein openings (not shown, mon in a form of Yale lock), with pins therein which are adapted to move the plungers 57 out of the opening and Hush with the surface of the cylinder, to permit movement of the cylinder when the key 53 is inserted therein. rl`he tube 11 extends, on the inside of the door, through hollow insilde knob 17; the latter being made up of half'f parts 18 and 19. The part 18 carries a sleeve 20 having its end disposed in bushing 21 itted at the inside end of opening 4. On the interior of sleeve 20 is secured, preferably by screw 21a, the sleeve 22, one end of' which adjacent to the right side of bolt 8 is provided with a cam 23 adapted to engage lugs 23a on bolt 8 when the inside knob is turned; its other end extending into part 18 of` knob 17, as shown in Fig. 1. A dog 25, provided with an opening 26 to accommodate the tube 11, and' provided with lugs 27, iscarried by rod 12 at its end in knob 17 by means of a pin 28 having its ends guided in slots 29 on each side of tube 11. The dog'25- is provided with one or more teeth 30 adapted to mesh with the teeth 31 of a circular rack 32 a cylinder 56 which has ecause com# on the interior Wall of part 18 of knob 17. Disposed between the dog 25 and a shoulder 33 on sleeve 20, is the setting mechanism 34, Which may consist of a part 35, adjacent to shoulder 33, loosely mounted on sleeve 22 and provided with handle 36 passing through a slot 36a in part 18 of knob 17, and a part 37, adjacent to dog 25, slidably mounted on the sleeve 22 and guided by pin 38 in slot 39 in the sleeve, the parts 35 and 37 having suitable cam surfaces in contact, as shown. A spring 40 is interposed between dog 25 and a Washer 41 near the end of tube 11. 'lhe part 19 may be provided With projections 42, tting indents 43 in part 18 to prevent rotation relatively there` to, and may be held in place by flange 44 on Washer 41, by means of a. screw 45 fitted in tube 11 and having its head 46 bearin against the flange. To the left of bolt 8 is the dead-lock mechanism, which may com` prise an annular dislv 47 movable on tube to engage projections 48 on bolt 8, the disk being provided with a flange 49 Whereby it is secured to rod 12 by means of 50 guided in slots 51 in tube 11.

As will readily be understood, the lock may be installed in the door by first placing in the hole 3 the lining 5, spring' 6, bolt 3 and guide-plate 9. Then by mounting on tube 11, with rod 12 therein, the outside knob and sleeve, the bushing 1G and disk 47, and passing the parts so mounted into the opening` 4 from the outside of the door to have the tube 11 pass through the slot 10 of bolt 8, whereupon there may be mounted upon the tube 11 from the inside of the door, the sleeve 22, sleeve 2O secured thereto, the parts 35 and 37 on sleeve 22, dog on rod 12, spring 40, part 1t) of the inside knob, Washer 41 loosely and part 19, and fitted in the tube.

lhe operation of the lock as above described may be as follows: The handle 3G a pin finally screw 45 may be of the setting mechanism may be moved to occupy a middle position in slot 36a (Fig. 2), in which case the dog 25 engages the circular rack 32- in the inside knob 17 and the inside and outside knobs are mechanically interlockcd so that by turning either knob the bolt S mayv be Withdrawn. lVhen the handle is moved' to either the right or left of the middle position, the dog is moved either to the rear or front of the circular rack 32 out of engagement therewith. In case the dog is moved to the rear of the mounted between the tube I deadlock circular rack 32, the rod 12 is moved to enf gage the head portion of cylinder 5G, and

though the bolt 8 'may be Withdrawn by;

turning the inside knob, the inside and out` side knobs are not mechanically interlocked until the key is inserted in cylinder 56 to move it and thereby the rod 12, to bring' the dog on the rod into engagement with the said sleeve,

. spring-pressed bolt bolt, a knob thereof, a second knob mounted on said circular rack. When the handle is moved to bring the dog to the front of the circular rack, the dead-lock mechanism is brought into play, so that neither the inside nor 0utside knobs can be turned to effect Withdrawal of the bolt on account of the disk 4 7 being moved to a position to engage the projections 48 on the bolt, as will be understood.

While one form of apparatus in Which the invention may be embodied has been illustrated and described, it is obvious that various modifications and changes may be made, and the right is reserved to all such modifications and changes as do not depart from the spirit and scope of the invention.
