Asbest show nin Fig. 4,;the latch bolt fcarrier is provided at one end with an enlarged portion :34 and provided centrally through this enlarged portion to extend lengthwiseof thecarrier'is ascrew threaded opening-35 in which is operativelyvmounted the screw most end" of thispenlarged portion also acts as a bumper for limitingtheretractive movement of the latch bolt earrier-as-hereafter explained. Surrounding the sides of this en-' largement 34 is a spring support 37, the inner end of which is arranged to passthrough the slotfl33v and is provided at each side of said slot with arcuate wings 38 for contact with the outer periphery of the knob shanks, the other end being slitted for the passage of the end'of the latch bolt 36.. A rectangular washer 39 is provided to extend across this'slitted end and servesas a'bearing for the-innerend of the latch boltspring 40. 'The other end of the spring 40 bears against the inner end of the nose 41 of the latch bolt and acts to yieldably hold said latch bolt in its outermost posi, tion. :Provided at the other end of the latch bolt carrier 32 atthe edges of the slot33 are I pairs. of abutments 42 -and 43 andjoining theseabutments, at right angles thereto, and at the extremeendof the slot 33 is a cross member 44 which coacts with the lip 25 of the locking member to hold the same in its operative position when looking the outer knob and spindle together. Screw threadedly mounted at one end upon the threaded end of the shank, 24, and projecting a shortdise tance into the recess 21 is a push bar .45 which extendsto and through an elongated recess 47, in the inner-knob and terminates atthe outer side thereofinia knob or button 48 by means of which said shank may bemanually forcedjinwardly. Provided within the re-.

' cess 21, between the inner end thereofand the adjacent end of the push bar 45, is a coil spring 49 which acts to normally hold saidpushbar and the shank 24 with its lip its outermost neutral position.

T The inner knob comprises a shank or sleeve 50 and the knob 51, provided centrally therethrough with an opening 52 for the reception of the splndle and provided in its inner-end end thereof is a concentric recess orgroove 55,

the inner end of which is adapted for engagementwith the end of a dog 56. The other end of the dog 56 is pivotally mounted within a'kerf 157 formed in the outer peripheryv of c the elongated hub 19, and is held normally pressed outwardly by a flat spring 58 or by any other suitable means. This construction An opening 59 is provided through the shank 5O immediatelyopposite the free. end of the dog 50 so that by the insertion of asuitable instrument such as a small nail or the like said dog may beiforc'ed inwardly into the ,ke'rf 57' and out of the recess 55 andpermit the removal of the shank 50 and its knob 51. The outer knob comprises the shank or sleeve 60 and the knob 61, provided centrally therethrough with a central opening 62 for thereception of the shank 63 of the auxiliary retracting member 28, a slot 64 being provided in theextreme outer end thereof for the reception of a suitable rotating n'1e1nber such as the edge of a coin-or the end of a screw.

driver. The inner end of the shank60 terminates in'a peripheral projection or lip 68 for engagement with the abutment-s 43 of the latch bolt carrier. 7 Provided within the inner end of the shank 60 is aconcentric recess 66 within which is positioned the auxiliary retractor member 28, and in the walllof this recess is provided a slit 67,-which; normally registers wit-lithe slot 23 of the spindle so that when thelockingplate 25 is moved to its locking position (as best shown in Fig. (4) it will extend partly into said slot and partlyinto; slit '67 thereby locking the, spindle, and shank together against relative rotation. Shank 60 is provided at its inner end witha projecting-lip 68 which coincides with. the projecting lip 30 of the member 28 and acts as a retractor for the latch bolt carrier when the outer knob is rotated. 'A cir cumferential groove 69 is provided aroundthefouter peripheryof the auxiliaryretractor member' 28 and an opening 7 O is drilled through the'shank 60 insuch man nerthat a pin 71 when positionedwithin said opening 70 will project partly into said groove and lock said retractor and shank together against relative longitudinal movement while at the same time permitting relative rotation.
