SPECIFICATION forming part of Letters Patent No. 689,809, dated December 2.4, 1901 Application filed April 23, 1.901.

T0 @ZZ whom it may con/cern.-

Be it known that I, FRANK P; KEENAN, residing at Portland,in the county of Multno- 'mah and State of Oregon, have invented certain new and useful Improvements in Locks, of which the following is a specification.

My invention relatesto improvements in that class of door-locks including a cylinderlock with a keyway in the knob for adjusting the spindle and connecting the knob with the spindle; and it comprehends in its general construction an outside knob normally held 'to turn free ofthe spindle and adapted to cooperate with the latch-bolt spindle and keyy operated devices for locking the said'outside knob with the said latch-bolt spindle. a My invention also seeks to provide an un-v locking means'of the character stated having a novel arrangement of latch-bolt-operating spindle carrying an inside knob, flxedly held thereon, adapted to coperate with the outside knob, normally held to turn free of the spin'- dle and relatively so combined with the spindle whereby the spindle can be shifted from the inside to engage with the outside knob to permit the spindle and the latch-bolt controlled thereby being operated by the outside knob, means being also included whereby the spindle and both knobs' connected thereto can be held from rotation. y Y

My.invention,furthermore,embodiesanovel combination of a cylinder bolt-locking latch and a spindle for operating it, means for adjusting the spindle and knobs coperating therewith, and a bolt-carrying cylinder applicable for a right or a left hand door, all being so arranged that the locking mechanism can be the more readily attached to the door than is ordinarilyvdone and the cuttingvout or mortising of the door materially reduced: In its subordinate features my invention consists in certain details of construction and peculiar combination of parts, all of which will hereinafter be fully described, and speciiically pointed out in the appended claims, reference being had to the accompanying drawings, in Which-- Figure l is a perspective View of my improved lock lnechanism applied to a portion of a door. Fig. 2 is a longitudinal section of my improved lock, taken practically on the line 2 2 of Fig. 1, the spindle being shown in Serial No. 57.097. (No model.)

Fig. 7 is a perspective view ofthe spindle and l l lthe inside knob devices. tive view of' the'. tubular spindle-engaging vmember heldin the outside'knob-spindle.

Figs..9 and 9a are cross-sections taken on the line 9 9 of Fig-S, showing, respectively, the normal condition ofthe several parts and their position when the key is inserted. Fig. 10 is a horizontal section of the tubular spindle, the parts thereof being in the position shown in Fig. 9.

Fig. 8 is a perspeci Referringnow to the, accompanying draw- 'I ings, in which like reference characters indicate like parts in all the figures, 1 designates a portion of a door, having an edge bored, bisected by the transverse bore b, the bore a,

having the latch-bolt cylinder held thereinl by the cap-plate c or bymaking the barrel or cylinder slightly tapering in the usual manner, the bore b being provided for the knobspindle;

rlhe bolt 2 may be of any approved springthrust kind.v In the drawings I have shown the latch-bolt 2 formed with the usual beveled edge 2, and said bolt is held to slide in a housing c3, detachably fitted in the cylinder 4, and the bolt 2 has an inwardly-extending shank 2b, that projects through and slides inV the member 5 of the tumbler, the end ofthe shank having a stop-liange 2C, and a spring 6 is fitted on the shank 2b to normally force the latch-bolt to its outermost position. The tumbler 5 is held to its normalposition by the IOO member 5 and springs 7 7, as clearly shown in Fig. 5.

8 designates the inside knob, to which is ixedly connected the hollow hub 9, the outer end of which is reduced to receive the hub 10 of the escutcheon-plate 10, in which the hub 9 is held to turn freely. The hub 9 has a non-circular bore to receive the adjustable shank or spindle 11, and the plate 10 has a counterbore 10b on its inner face to permit of a proper application of the spring-clamp 12, that fits an annular groove 9I in the end of the hub 9 to hold the same from pulling away from the plate 10. The hub 9 has a series of connected apertures 9C, 9d, and 9e for the insertion of the adjusting-screw 13, and the hub 10a has an aperture 10c in line with the aperture 9e in the hub 9, the reason for which will hereinafter be explained. The spindle 11 has a number of threaded sockets 11 to provide for a proper connection thereof (on doors of different thickness) with the inside knob and also provide for a proper longitudinal adjustment of the spindle relative to the two knobs. The adjusting-screw 13 hasr a reduced shank 13 and a milled head 13".

14 designates the outside knob, which has a central bore in which is lixedly held a cylindrical casing 15, in which is detachably held the key-receiving barrel 16, held locked to turn with the casing by the screw 16". (See Fig. 2.) The knob-casing 15, with the barrel- 16, is held to turn freely within the hub 17a of the escutcheon-plate 17, and thesaid casing 15 is held from pulling ont when adjusted to an operative position by the spring 18X engaging the groove 15X and the counterbore 17x of the plate 17, as shown. The barrel 1G, the peculiar construction of which is best shown in Fig. 8, comprises a fixedly-held portion and an inner slidably-held member, the inner end of which is made with a noncircular bore of a diameter to move onto and Connect with the end 11x of. the spindle 11. The sliding member 16x of the barrel has an outwardly-projecting spring-plate 19, made fast thereto bythe screw197, the tension ot' said plate being such as to project its free end 19y down, as shown inFig. 9, and the said plate 19 has a slot 19, into which the toe end 18b of the latch 18, pivotally mounted on the stationary end of the barrel 16, projects. The outer end of the plate 19 extends into a recessed part ot the member 16, and its spring-pressure is such as to normally press down on the heel 18n of the latch, and thereby move its locking-toe 18 up through the slot 19X in the plate 19 to hold said plate from moving inward toward the knob-spindle, and the said toe, as will clearly be seen by reference to Fig. 3, lies in the plane of the key-slot 20 in the barrel, and the normal position of the outer end of plate 19 is in a plane below said key-slot, as shown, and said end has arbitrarily-arranged studs 19, the purpose of which will presently appear.

The manner in which my improved lock is operated is best explained as follows: When the parts are in the position shown in Fig. 2,- the out-side knob is held to turn freely withoutaecting the spindle 11 or the inside knob,- the said spindle in the said figure being shown adjusted to be operated by the inside knob only. When it is desired to set the lock so it can be key-operated from the outside, the spindle l1 is shifted by means of the adjusting-screw 13 to the position shown in Fig. 3, and when in such position the outside knob is still left to rotate freely and the spindle held to be turned by the inside knob, the outer end of the said spindle being, however, sufiiciently projected to be engaged by the keycontrolled devices in the outside'knob, which devices when shifted inwardly by the insertion of the key connect with the spindle, as shown in Fig. 3, and permits the lock being operated from the outside, which is done by key operation only. To hold both the inside and outside knobs from turningand the latchbolt from movement, the spindle 11 is shoved into the position shown in Fig. 4, and in this adjustment the screw 13 is made to engage the aperture 10c in the fxedly-held hub-plate 10, which holds the spindle and the knobs from turning. To connect both the inside and outside knobs so they will move together, the spindle 10 is shifted to the positionl shown in Fig. 4, which permits of the'latch-bol-t being manipulated by either knob in theusual manner. In operating thel lock with'the'key it should be stated that as the key is pushed inward it will engage the toe 18bof the'latch 18 and move the said toe down out of engagement with the plate 19, and as the'toe 18" is thus pushed down the heel part 181 of the latch presses up against the corresponding end of .the plate 19, exerts-a quick movement of the same, and causes thestuds 19c to'enter correspondingl y-'arran ged holes 21 in the key 21, and thereby interlock the key with' the plate 19. This having been done, further movement inward on the key 'will serveto force the sliding section of the barrel out until it fits over the opposing end of the spindle 11, with which it is then locked, as clearly shown in Fig. 3, and when thus adjusted a turn of the key will rotate the barrel, the spindle 1l, and the latch-bolt, and at the same time turn both the knobs, it being u'nderstood that the correlation of the plate 19, latch 18, and the keyway is such that when the pressure on the latch 18, exerted by the key, is removed the spring of plate19 will force the studs 19c out of engagement with the key and permit the withdrawal of the said key and at the same time throw up the toe ot' latch 18 to hold the sliding member of the barrel back to its normal position-that is, lreleased from the spindle 11. The plate 19 and the key do not disconnect until after the sliding barrel-section has been drawn back.

From the foregoing description, taken in IIO ` construction will be readily apparent and need not be further set out.

While I prefer to arrange the several parts of the mechanism as illustrated in the accompanying drawings and described, the said' parts may be modified and details varied without departing from the scope of the appended claims.l

The escutcheon- plates 17 and 10 may be secured-to the door in any approved manner. I prefer, however, to form the escutcheonplate 17 with inwardly-projecting hubs 172, having threaded sockets, and the escutcheonplate 10 with apertured hubs 10X, and to have the said hub seat in apertures .fr in the door, as clearly shown in Figs. 2, 3, and 4, by reference to which itwill be seen that when thus arranged the two escutcheon-plates can be firmly held by the screws 10i'.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is
