noonLooK' Application'led September 3, 1932. Serial No. 631,606..v

This invention relates to improvements in door locks of the latch bolt type used on outside doors, and of that general character in which the external door knob is noi-- nially disconnected 'from'the' interior knob the spindle and the inner knob and this was j found to v be an objectionable feature. for;v

various reasons. The structure of the present invention therefore particularly represents improvementsover this previous one;

`my principal object being to retainV all the advantageousffeatures of the previous form of lock by providing a .releasable interlock ing meansbetween the router knobl and the spindle arranged to be actuatedat will without any axial movement of the spindle or` either knob being necessary. Y

The above and otherobjects will be ap parent from a perusal of the following specification in connection with the drawings accompanying the same.

These objects I accomplish-.by means vof such structure and relative arrangement of parts as willfully appear by aperusal .of the following specification and claims.

In the drawings similar charactersofl reference indicate corresponding parts in the several views:

Referring now more particularly to the characters ofreference on the drawings,the

numerals 1 and -2 denote the outer and inner escutcheon plates of the' lock,` abutting `against the opposed .faces ofl thev door 3' near its free edge and surrounding a circular' opening t drilled throughv the door. An`- other relatively small opening 5 for the bolt housing 6 is drilled from said edge of the door to the' opening 4: axially thereof.

At itsinner the spindle non-turnably engages the sleevelf? ofthe inner knob 1 8`to whichit vis remova-y vby a segmental rfitainin'g vwasher 13. disposed betweenfthe plate 11 andthe V74collar 7' and.

turn but cannot be displace'd 5,5" section on the line *7g-7' bly secured by a screw 19 in the customary manner. Y

At its outer end the spindle has swivel jointed connection with an extension 2O formed at its outer end with an enlarged flange 2l. The extension has a transverse notch 22 in its outer end adapted to be engaged by the tip of the proper key inserted in the barrel 23 of a lockot standard charaeter which is mounted in the outer knob. .This arrangement enables the spindle to be turned and the ldoor to be opened whether the outer knob is free to turn at the time or not. A cup 24 seated in the outer end of the sleeve 8 against inwardmovement engages the fiange 21 to prevent inward movement of the spindle; outward movement being prevented by the engagement of the notched end ofthe liange with the adjacent end of the lock barrel. Y

Slidable on the spindle and its extension and in the sleeve 8 is an inner sleeve 25, normally urged outwardly or against the cup 24 by a spring 26. The bore of the sleeve 25 at its inner endis of reduced sizeand is square as at 27 to-.slidably and non-turnably engage the spindle; said spindle in the plane of the normal position of the square portion 27 being rounded as at .23 or otherwise reduced in size so that it can turn in said portion 27. The contacting surfaces of the sleeves 25 and 8 where they slidably engage each other are of hexagonal or other noncircular form as at 29 so that'they must turn together.

The inner end of the sleeve 25 is normally disposed inwardly ofthe plate l1 and the exposed portion of the sleeve is provided with longitudinal opposed slotsv 30. Ilfhese slots are engaged by lugs 31 projecting from the bore of a ring 32, the lugs bearing against the back end of the slots. The ring is notched on its sides as at 33 to slidably but non-turnably engage lugs 34 struck up from and extending axially of the plate 1l.

From the above description it will be seen that the spindle Vis normally turnable in the outerr knob so that it cannot be turned by the rotation of said knob. OnA shifting lthel lsleeve 25V lengthwise against the resistance of the spring 2G untilthe square bore 2 7 of the sleeve 'engages the' squareporti on ofv the y spindle, the knob and spindle are locked together and Amust turn as a unit.V At the same time the sleeve 25 is moved sovthat the ring 32 is clear of the lugs 34, so that the knob can be turned. ,This movement is imparted to the sleeve from the inside of the door bythe following means. i Y

Turnably engaging'the sleeve 25 immediately in lront'of the'ring 32 andl projecting` radially therefrom is an Varm 35, held against longitudinal movement on the sleeve bya snap washer 36.` The arm 35 is Vconnected to another lradially extending arm "37 `dis-1l vsaid housing projects.

posed inwardly of or on the opposite side o i the bolt housing@ by a longitudinally adjustable connecting unit 38. This unit is preferably in the form of cooperating sleeve and screw members which extend parallel to the spindle and pass just behind the inner end of the housing G, as shown in Fig. 3.

The arm 37 is rigid with an actuator sleeve V39 which surrounds the spindle in clearance relation thereto and which projects through 'the plate 2 and into a collar 40 which turnably engages the outer end of the knob sleeve 17. This collar is turnably mounted in the plate 2 and has an enlarged flange 4l on its end which cooperates with a shoulder 42 on said plate. The flange is turnably clamped between the shoulder and a spring washer43 set in the plate 2 so to prevent axial movement of the'collar in Veither direction without interfering with its rotation. v Y

Pressed into the collar and practically` forming a part thereof vis a plate 44 turnably engaging the sleeve 3 9 vand holding the same centered on the spindle; said plate having opposed lugs 45 projecting from about the bore. rlhese lugs engage opposite helical grooves 46 cut in the sleeve 39 so that as the collar 40 is turned said sleeve will be moved lengthwise, imparting'a corresponding` movement tothe sleeve 25'through' the various connecting elements. j

The pitch and length of the 'helical grooves is such that with about half a turn of the collar the sleeve 25 will be moved to bring` the square bore portion 27 over the square portion ofthe spindle and at the same time move the member 32 clear of the lugs 34,so that the plate and sleeve 25 are tree to turn. l

rlhe rotative vmovement is thus imparted to the collar at will by a radial handle or knob 47 secured thereto in a convenient location preferably adjacent the plate 2. Rotation of the actuating'sleeve 39 is positively prevented bymeans'of lugs 48 engaging longitudinally extending grooves 49 in said sleeve. These lugs are mounted on a plate 50 coun'tersunk in the plate 2 and bored to slidably guide the sleeve 39. The plate is mounted 'in a definite fixed position relative tothe plate ll. and the various associated parts, and so that the arm 37 is radially parallel to the arm 35, by meansof screws These exten d across the housing 6 above and below the same4 andv engage ears 52 formed on the ends spaced walls projectingfrom the plate 1l and between which l By means of this connection the plate l will bellrmly clampedl against the outer faceof'the door so that individual screws through the same are unnecessary, and the plate 50 is alsov firmly' clamped against'the inner face 'of the door. The lugs 48 project inwardly of the bore y of the sleeve `39as shown `in lFig. 1 0 and serve as `stops for one end of a compression spring 54 mounted in said sleeve about the spindle. `The opposite end of the spring bears against a shoulder 55 formed with the arm 37 so thatsaid spring tends to force the sleeve outwardly of or away from the plate 50." l

4When the sleeve 39 is drawn toward the plate toa'vspindle coupling positionby the rotation ofthe collar 40 it will remain in that position until thecollar is intention-ally retracted.l Upon such retraction being affected the pullof the spring-.2G causes the ringl 32 to re-assume its engaged position with the lugs34 as soon 4as either knoband spindle are turned sothat the notches Y33 register with said lugs. Thisregistration will take'place before any knob turning movement can be had after the collar has been once turned to its retracted position.

From the foregoing description it will be readily seen that I have produced such a device as substantially fulfills the objects of O the invention as set forth herein.

While this speciication sets forth in detail the present and preferred construction of the device, still in practice suoli deviations from such detail may be resorted to "5f y as -do not form a departure from the spirit of the invention, as defined by the appended claims.
