vThe present-.invention relates to an..improved latch, particularly for, automobiles ef the type having an inside and van outside operating handle, andin which the outside handle isadapted to be latched againstv oper-` ation by manipulation of the insidellandle. The latchis'especially adaptedfor use upon doersof closed carsbeing applied to all but one of ,the doors, and which latter is adapted to be 4latched fromthe outside. l] pa rticu larly propose to provide an outside handle roll-back adaptedito operate uponthe latch bolt.l through anv intermediate retracting member, and anv inside handle roll-back adapted Vto operate upon the latch bolt through a retractingand Kl'atching member adaptedvup'onl manipulation in one direction to retract the latch bolt independently of said intermediate member, and in the other direction toi operatelatchingmeans,to latch the intermediate member again'stfloperation by the outside.V handle roll-back. f

Other objectsareto provide a latch of sim# ple .and inexpensive construction, and. which will be positive and reliable in operation.

sheet metal frame or base plate`10 having a faeeflang'e 11 ben't therefrom 'at oneend and within which a rectangular latch bolt opening 12 is provided. Aianged-lip portion 13 is bentg inwardlyjrom the` upper` edge of the epening to provlde a bearing for the latch ot. s y y' The latch bolt comprises a nose portion 14,

riveted at 15 to a sheetmetal bolt plate orbar 16 guided` at its inner end in a transverse .bridge member 17 having downwardly bent ends 18 and 19 secured to the base plate by bent lugs 20 and 21, the bolt bar being guided at. one edge through engagement with the end 18 and at its other edge againsta shoulder formed bya bend 22 `in the top ofbridge member. A coil spring 2 3, mounted `upon the base by means of a clip 24, has its end en'- ga-ged against a vshoulder 25H01l the bolt,

formedby bending the same adjacent the nose portion 14, and normally presses the boltA to `its projected portion` An upwardlyV projectving lug |26 is provided. atthe upperedgeiof the bolt, and isadapted to be engaged by the retracting means offboth the `outside,and inside handleroll-back, presently tobefjmore fully described.

The outside hanne 'roll-tack 27111515 'it '1mb` 28 rotatably engaged in apertures l29 inthe base plate and ina retaining plate 30.` rlhe plate 30 is Vsecured by a lug 31 formed there#` on to the viange 11= and is'also secured supported by a ilangef32 bent upwa dly from thebase plate and having lugs '32.swaged' in apertures in the plate '30. The flangel 32`also serves as a guide for', the upper edge of" an intermediate rtracting slide bar 34 engaging -100 the base plate and provided at its forward end with an upwardly bent iange 35 against which the roll back engages. The slide bar 34 is further guided by a lug 36 bent upwardlyv from the base plate and engaging the lower edge' and also throughvengagement of its upper edge with the/flange 19 of the bridge penden'tly member 17. f l :A projecting lug l37 is provided at the lower Vedgeof theslide bar 34which engages the forward side of the upwarly projectinglug 26 of the latch bolt bar, the latch 'bolt spring 23 being adaptedto normally press the bolt and the bar 34 forwardly against-fthe rollback, thereby limiting the'projection ofthe bolt and `yieldablyq retaining ytheY roll-back in' its normal position against the iange 11.

The arrangement permits free retrac'ting` movement ofthe bolt, through pressure ap-.

pliedat its nose, 'as in closing thedoor, -indeof the retracting bar and the roll- A retractor bar 38 for the' inside handle roll-back is slidably mounted on the base plate beneath the bolt jbar 16, being guided at its upper edge by engagement with the lower edge vof the outside'roll-bac-k retractor bar 34, and 'at its lower edge by engagement with the ange'lS of the bridge member 17 and aflange 39 bent upwardly from the base and arranged in line with theflange 18.

lThe forward end ofthe bar 38.y is bent up- Y wardly, as at 40,V into engagement with .the

'Ver' under surface of the latch bolt bar, and is provided at the upper edge with an upward-V ly bent lug 41 engaging the forward surface of the lug 26 of thel bolt bar, being .normallydisposed in aligned relation with the lug 37 Y ofthe outside roll-back retractor bar 36, as shown Fig. 1. rI he bar 38 projects rearv wardly from thebase plate, where itis pivotally connectedat 42` to one end of alink 43V which is connected at its other-end to the remote control inside' handle roll-back 44, 'placed at any suitable point upon the door frame; V l As clearly shown i-n Fig. 9, the retraction of the bolt throughoperation of'thefoutsidehan- Y 'so the inside handle rollfback and d-le roll-,backand the bar 34 is independent of thebar 38, while, as shown inFig'. 10, thev retraction-of thelb'o'lt through operation of y the bar 38" is independent ofthe barz34'. p 1 l The intermediateI 'retractingv bar 34 and: the

outside handleroll-back 27 are adapted tof be :latchedl ,againstjmov'ement by movement of 'the inside handle rollba'ck' and the bar '38 `in e the opposite Ydirection tothe retractingmovement. For this purpose 'a transversely slidable latching barv 45 .is mounted beneath the vrbridge ,member` 17, between the inside .roll- 'back fretrac'ting baru38iand the bolt bar "16,

being guided at one endI by a .tongue'46' engagvingfa slot`47y intheflange 18 ofV the bridge member, and' atits other end by adown'- wardly bent lug 48 extended through an a2 gular slot 49 in the bar 34 and engaged in a rectangularslotO in the base plate. The slot 49 is of right angular shape, its longitudinal portion v being relatively elongated and adapted to permit normal retracting movement of the bar-34 in the lower or inoperative v position of the latching bar, (Figs. 1 and While its,A transverse :portion 1s cofextenslve ,with the slot 5.0Qinthe base plate, andjisl adapt# Ved through engagementV of the lug v48 therein, in the upper-or operative position of the latching bar (Fig. l11), to latch the barr34 against movement.

The latching bar is rovided with a downwardly projecting stu 51 engaging la slot 52 inthe 'retracting bar 38,v the, slotted portion ofsaid bar being embossedV upwardly, as at 53, so as tol provide clearance for theV stud 51 withrespect'to the base plate. VThe 'slot l52 is of' obtuse angular formation, and-includes' a'lower relatively long longitudinall portion in which the stud is engaged in the normal position and permits retractingmovement of the bar' 38 without imparting movementfto the rlate-hing bar (Fig. 10), an angular por.
