LOCK.

SPECIFICATION forming part of Letters Patent No. 672,594, dated April 23, 1901.

' Application filed March 16, 1900. Serial No. 8,925. (No model.)

To all whom it may concern.-

Be it known that I, PETER VOLGUARD GOR- NILS, a citizen of the United States of America, and a resident of Seattle, county of King, and State of Washington, have invented certain new and useful Improvements in Locks, of which the following is a specification.

My invention relates to improvements in look mechanism, and is especially adapted to that class of locking and latching devices designated as mortise-locks; and Ihave for the objects of my invention to provide simple and efficient mechanism for looking a door that can be readily substituted for ordinary knobspindles in latches or locks of the mortise type, which employ a rotatable spindle to retract the latch-bolt; also, to provide means for engagement with the door-stile whereby a knobspindle may be locked from rotation from one or both sides of the door. I attain these objects by the construction, combinations, and arrangement of parts as illustrated on the accompanying drawings and set forth in the followingspecification.

With reference to the drawings forming a part of this specification, Figure 1 indicates aportion of a door-stile viewed at right angles to line 1 2 of Fig. 4 andindicated in transverse section to disclose the lock-case with a portion thereof broken away to uncover the knob-spindle, which is indicated in longitudinal section on line 1 2, Fig. 4 with its attendant parts indicated in relative position when the spindle is locked from rotation. Fig. 2 is an end elevation of the spindle-knob on the left in Fig. 1, but indicated with the cap thereof and its attendant mechanism removed to disclose the spring adapted to press the locking-bolt. Fig. 3 is a similar view of the spindle-knob disclosed on the right in Fig. l and the cap thereof removed and the tumbler-case therein indicated in transverse section on line 3 4, Fig. l, to disclose the arrangement of tumblers provided to engage the push-bar, the yoke of which is also disclosed in transverse section at each side of the tumblers, and a portion of a key is indicated as about to press the tumblers to release the knob-spindle for rotation. Fig. 4 is an end view of the spindle-knob disclosed on the left in Fig. 1, and which is preferably the inner knob on all ordinary doors, and is indicated with a portion broken away to dis close the plate provided on the door-stile to receive the detent carried by the locking-bolt, which is positioned in the knob-spindle and is indicated therewith in transverse section, and with the detent engaging the plate, and a portion of the door-stile and lock-case indicated in relative position. Fig. 5 is a transverse section through a portion of the doorstile and disclosing portions of a lock-case and esculcheon with a modified form of lock-plate in relative position. Fig. 6 is a plan of the modified form of lock-plate disclosed in Fig. 5. Fig. 7 is a perspective view of one-half of the casing provided in the outer knob-spindle to support the tumblers; and Fig. 8 is a side view of the knob-spindle at right angles to the view thereof disclosed in Fig. 1, but with the spindle-knobsand portions of the locking mechanism removed.

Similar characters of reference designate corresponding parts throughout the several views of the drawings.

With reference to the accompanying drawings, forming a part of this specification, A indicates the stile of any ordinary door; B, the frame of any ordinary mortise lock or latch, ordinarily termed the lock-case, and indicated in Fig. 1 with a portion broken away to disclose the hub b, adapted to operate the latch mechanism, and indicated in transverse section to show the knob-spindle O passing therethrough and engaging therewith in the ordinary manner.

At opposite ends of the knob-spindle O are provided the hollow knobs D and D, the former preferably applied at the inner and the latter at the outer face of the door, and each is provided with a removable cap, as d or d, which is secured in position in any well-known manner. These knobs D and D and the caps therefor are preferably formed from sheet metal, and the hubs 24. thereof are provided with interior reinforcements or castings, as d and 01 which are each provided with a suitable recess 20, adapted to receive the ends of the knob-spindle G, and suitable screws, as 4 and 5, are provided to secure the said parts together in the well-known manner, a plurality of threaded apertures, as 6, being provided in the reinforcements and spindle ends to receive said screws, and therelatter extending from said aperture to the. The slot is is i by provide means whereby the spindle-knobs may be adjusted to accommodate doors of various thicknesses, as in the ordinary arrangement of door-locks of the mortise type.

At each face of the door is provided a suitable escutcheon, which is positioned concentric with the knob-spindle O, and the outer escutcheon E is preferably provided with an extended rim f, which encircles the hub 24 of the spindle-knob D and provides a bearing therefor to support the knob-spindle and serves to protect the screw 5 from manipulation when the lock parts are assembled in operative position on a door. The inner escutcheon E is also provided with a rim to receive and provide a bearing for the hub 24 of the spindle-knob D and has an annular recess f provided in thetunder surface of the base-flange 2i thereof of suitable diameter to receive the rim of the lock-plate F.

The base-flanges 21 of the escutcheons E and E are preferably of suitable diameter to receive bolts 6 in suitable apertures 22, which are threaded in the outer escutcheon E to engage the ends of these bolts and are positioned diametrically opposite to accommodate the bolts e at opposite sides of the lock-case B, whereby the bolts pass entirely through the door-stile and serve to secure the escutcheons and lock-plate F in position, and thereby provide rigid support for the knob-spindle O, with the hubs ot' the knobs thereof engaging the rims provided on the escutcheons to receive the same.

The knob-spindle O is preferably rectangular in cross-section and of suitable dimensions which adapt it for substitution in place of the spindle employed in ordinary latches and locks of the mortise type and is provided with slots 7c and extending longitudinally thereof, the former preferably extending from the inner end of the spindle to a point adjacent the position of the'lock-plate F and terminating at an aperture 10 provided transverse the knob-spindle at this point, and the outer end of the knob-spindle. provided to receive a suitable locking-bolt,

as H, which is preferably rectangular in crosssection to correspond with the slot It, in which it may be adjusted by longitudinal movement. The locking-bolt thus positioned in the knob-spindle is preferably produced with its inner end providing a suitable detent h, which engages the aperture k and extends laterally from opposite sides of the knobspindle to engage with the lock-plate B when so adjusted in said aperture by a movement: of the locking-bolt, the said plate being suitably provided with an aperture f concentric with the knob-spindle and having radial slots g in the periphery thereof of convenient form and size to receive the projecting ends of the, detent h, whereby the knob-spindle C may be locked from rotation.

The aperture 10 provided in the knob-spindie, is of sufficient length to permit the detent h to move just beyond either face of the lock-plate F and to release therefrom, and thus unlock the spindle for rotation with the detent at either side of the lock-plate, as determined by the operator.

The locking-bolt H is extended in length beyond the inner end of the knob-spindle C and enters the hollow knob D to engage a suitable spring, as H, preferably formed from sheet metal and secured to the inner wall of the knob, with its free end pressing upon the outer end or head h of the lockingbolt and having a suitable bifurcation to provide for the introduction of a suitable screwbolt, as n, to the head h, in which a suitablythreaded aperture n is provided to receive one end of said bolt and is of sufficient depth to permit of a longitudinal adjustment thereof. the end of the locking-bolt- H and beyond the outer surface of the "knob-cap d to provide the axis for a rotatable knob K, which is preferably provided as means foradjusting the locking-bolt to withdraw the detent h from the lock-plate F, andlmay also be employed by suitable adjustment to prevent the for resisting the inward pressure of the spring provided in theperiphery of the aperture 01 of the knob-cap-d to receive said pin when the knob K is resting in an inner position, with the detent h forced by pressure of the spring H to engage the lock-plate F and to press upon the inner end of the push-bar H The push-bar H is preferably employed to oppose and resist pressure of the spring H; but, if desirable, the knob K may be adjusted for this purpose by entering the screw 'n still deeper into the head h, thereby causing the under surface 7 of the knob-head to bear upon the outer surface of the cap at when the locking-bolt H isadjusted to register the detent h with the lockplate F, and thus oppose movement of the detent beyond the lock-plate. In this manner the use of the push-bar H as a stop to oppose the pressure of the spring H is avoided and the locking mechanism indicated on the inner end of the knob-spindle is adapted to operate independently of the mechanism indicated on the outer end thereof, and

means are thus provided whereby the spindle may be locked from rotation and released for rotation at one side of thedoor only. It will be understood that the pin which provides the shoulder 23 should be reduced in length proportionately as the knob K is advanced toward the head h of the locking'bolt by the adjustment of the screw-bolt 'n, that the end thereof will clear the outer surface of the cap 01 when the detent h contacts the wall of the aperture W, as indicated by dotted lines in Fig. 1, and the knob K may then be given a partial rotation to carry the pin 15 clear of the slot 11., when it may rest in a position indicated by the dotted lines in Fig. tand secure the knob in its adjusted position and permit the knob-spindle C to be rotated.

To provide means whereby the detent h may be adjusted from the outer spindle-knob Dto lock and unlock the knob-spindle, the push-bar H is preferably introduced and is adapted to engage the slot K for longitudinal movement therein,with its inner end abutting the detent h and the outer end thereof providing a yoke 10 which is adapted to inclose a plurality of suitable tumblers, as T, located within the outer knob D, and a suitable button b is provided at the outer extremity of the yoke K which button projects outwardly a suitable distance from the cap (1 to permit said button to be pushed inward to force the detent h from the recess a, provided in the door-stile, into which position-it is pressed by the action of the spring H when the tumblers T are adjusted to permit the inner transverse side 8 of the yoke 70 to enter the wards y, providedtherein.

The tumblers T are preferably positioned in a suitable casing d which is formed integral with the reinforcement d and is suitably chambered and slotted to accommodate the movement of -the'push-bar H and the tumblers T and to provide for the support of a plurality ofsuitable coiled springs, as s, which are engaged at one end with the tumblers to press them toward the keyway v and are suitably mounted on a stud, as 9, and are confined for pressure bya pin 10, which engages the opposite ends thereof. This casing is preferably formed in halves, one of which is disclosed by Fig. 7 and provides a chamber 11 to receive the tumblers T for adjustment transverse the spindlek nob and an extension 12 of said chamber to receive the keyway t, which is preferably formed of sheet metal bent to provide a casing rectangular in cross section and of less width than the chamber 12, whereby projecting ends t, which are formed on the tumblers T, are received between one wall of the chamber 12 and the keyway, and the tumblers are thereby more perfectly supported. The casing d is also provided with a suitable recess to receive the end of the knob-spindle, and a slotted extension 14 of said recess is provided to accommodate the push-bar H and yoke and each half of the casing is. provided with lugs 15,

which provide support for opposite ends of the studs 9 and 10.

The tumblers T may be provided in any suitable number and with wards y transverse the inner edge thereof equal in width to the thickness of metal forming the yoke 163 and adapted to receive the side 8 thereof when the tumblers are adjusted by pressing upon a suitable key, as P, introduced in the keyway 11 to force the tumblers against the pressure exerted by the springs s.

The adjustment of the tumblers T by the key P permits the spring H to adjust the push-bar H and move the detent h into annular recess a, and thus unlock the knobspindle C for rotation, and when desirable to again lock the spindle the button I) is employed to force the push-bar H against pressure of the spring H until the detent h is received by the notches 9, provided in the lockplate F, and the side 8 of the yoke 10 clears the wards y, when the springs 3 force the tumblers T to movement and the inner edges thereof engage with the side 8 to oppose movement of the detent by the spring H, and the knob-spindle is locked from rotation, as indicated in Fig. 1.

It will be understood that the locking-bolt H and push-bar Pl are positioned within the knob-spindle with reference to the side sur: faces thereof, that the spindle may be readily substituted for the ordinary knobspindle employedin mortise-locks, also that the lock plate F may be modified, as disclosed in Figs. 5 and 6, and may comprise a section of plate F with a suitable aperture f adapted to receive the knob-spindle and permit free rotation thereof, and having suitable notches g in the periphery to receive the detent h, and

suitable radiating leaves or arms g of greater between by pressure of the screws 6, and a suitable recess is provided at each side of the plate F to permit rotation of the detent h when disengaged therefrom.

By simply detaching the knob K the looking mechanism may be modified so as to be operative from the spindle knob D only as the spring H presses the detent h to engagement with the slots 9 of the lock-plate F and to disengage from the opposite side thereof. Thus the push-arm H and tumblers T are adapted to provide means wherebythe detent may be retained in engagement with the lockplate to lock the spindle or released therefrom by the use of a key, as P, to enter the recess ct and free the knob-spindle for rotation when the button 5' may be pressed upon by the operator to move the push-arm inward and force the detent into engagement with the lock-plate, and the tumblers are forced by the springs s to move transversely with reference to the movement of the push-bar lLO and to secure same from outward movement, as heretofore explained.

When the locking mechanism heretofore described is to be provided for doors of various thicknesses, it is found desirable to provide the push-bar H of sufficient length to permit proper operation of the mechanism when the knob D is adjusted to extreme outer position on the knob-spindle. The inner end of the push-bar may then be reduced in length, if it be found necessary, to adjust the knob inward on the spindle.

It will be clearly understood that the knob K may be moved longitudinally with the innerspindle-knob by simply turning the screwbolt n, as heretofore described. Furthermore, it is apparent that the detent his so positioned as to be adapted for engagement with the slotsin the lock-plate when the knobspindle is lying in a normal position, as determined by the latch mechanism contained in alock-case, as B,and the position of a latchbolt, as B, protruding from the lock-case to each end of the spindle, whereby the detent Lock mechanism is thus provided whichi may be readily substituted for the knob-spin-l dles employed in ordinary mortise locks and.
