The latch construction wnich I have partially illustrated in the accompanying drawings, constitutes no essential feature of the present invention, and it will be clearly understood as this description proceeds that the subjectmattei' of this application is capable of adaptation and use in connection with many differentI` types of door latches now known in the art and which might be employed for many different purposes. In all cases where a quickly attachable and detachable connection between an operating shaft and a part to be actuated thereby may prove to be of material advantage, the invention to be presently described will be found desirable. However, since the invention has been used in connection with automobile door latches and found particularly serviceable and satisfactory, I have selected this application of the invention for illustrative purposes, and in the accompanying drawings have shown a portion of an automobile door 5. The inner `face of this door is mortised in the usual manner to receive the latch casing 6 within which the latch bolt and the projecting andretracting mechanism therefor are mounted. The latch bolt retracting means includes the customary rollback 7 which is journalled for oscillating or rocking movement at its ends in spaced parts of the latch case 6. This rollback may be of any desired form requisite to insure its proper cooperation with a part of the latch bolt whereby the bolt is reti'L cted when said rollback is oscillated in one direction. In every case however, the rollback 7 is provided with a bore 8 coincident with its axis of oscillation, said bore being of any desired polygonal shape in cross section. Preferably, the opposite ends of the rollback 7 are tiush with the outer surfaces of the inner and outer walls respectively, of the case 6.

The door structure 5 has a transversely extending handle shaft receiving opening l) bored therethrough substantially in line. with the rollback 7. In the outer end of thisl opening, a combined handle shaft bearing and escutcheon member l() is secured. '.lhis member which is lnefcrabl)v in the lform of a, sheet metal bushing having an enlarged annular head at the outer lace ol the door within which a yieldable bushing of telt or other compressible material is contained, coustitutes no essential part ol the present disclosure, as it is full),Y shown, def-ieribed and claimed in my tao-pending` application lor patent Serial ifo. (i$)t,-l;2t, tiled :dai-rh Il. lllzl. It will therefore. sullicc to state that', tiis member atiords a con'lormahle hearing .support for the handle shaft :uilon'ratirally aecommodating` itsell to any discrepancies in axial alignment between the opening` il and the rollback 7 and likewise providesl a more or less ornamental escutcheon :mrrounding the handle shaft at the out er :tare of the. door.

The handle shaft includes a cylindrical portion ll extending through the member l() and a. reduced portion lil ol' the same cross sectional form as the bore S ot the rollback 7. The end ot' this `shalt .section 1L) is provided `with a central longitutflinally extending slit. or kerf lll therein to provide the two laterally expansihle and contrmtable portions l-it. The end faces ol' thesey shalt portions l-il are preferably slightly rounded or convex as at l5 and the, outer side edge o t each of said portions is formed with a narrow flange or projecting lip lt), the purpose of which will hereinafter become apparent. rlhe inner faces of the portions 'llol the shaft end at their extremities are each provided. with a groove or channel i7. the said grooves being tapered or inclined inwardly from one side face of the. sha l't end towards cach other to the opposite side l'aee thereoll as clearl.v shown in li`ig. 5 ot thel drauinggs.

ldlithin the slot or kerl' lil tin-re is loosely arranged a. stop pin lt ol` rectangular Vorm in cross section, the opposite ends ol' which are angularlv extended iu reverse direeliouzas at lf) for engagement over the opposhe side faces ol' the shalt. is .shown in Fig; l'. if desired. this stop piu may be ol` general I-shaped form having the heads lil on its` opposite ends each extending upon opposite sides of the shank portion ol' the pin. l lowever, these suggested forms are not essential and other means for this purpose might be readily devised.

It will be understood that the lenggjlh ol' the slot 13 in the end ot the shaft and the location of the. chaiinels or 5l-cores li is aecurately predetermined in :xt-,cordamre with the length of the rollback. '..`li1is.l when this shaft end is inserted into the rollback here from the outer end thereof. the proferlingfj i'ianfes or lips l() having the rounded end faces bear against they opposite side edge-r ot' the rollback bore and as l'ircssure is applied,

llt)

however, said spaced yieldable lefs curved in ge eral conformity with the curved see-tions 1 of the groove 17. It will therefore. he

through said grooves, as the ends-i of the lef -i expandingl lie-y are f and li" understood that as this key Q1 is 'l'orred 25a approaeh'the intermediate sections ii of the `grooves, they will be sprzu'ig inivardiv towards each other and after passup; said, intermeoiate portions otI the grooves w expand outwardly to their nornial positie so that when the wedge or lcey Vis tina driven home, it will be securely loelved hold the split portions of the shaft in er.n panded relation to the bore of the rollback. In this instance, I have shown the lcey member 21 at its 'vider end .Lnovided with z central opening '29 to receive a pin or stur 3G in the end of a tool bar 3l wherel'iy key may be readily inserted into the 17 or extracted from its applied position.

In the inodilieation shown in Figs. l2 and 13, the entfanee ends of the key-receiving; grooves shown at 17c extend in substantially parallel relation to each other and the remaining' portions of the grooves have their hase walls curved to the opposite side face of the shaft end at 17d. The longitudinally split expanding lrey is provided with the relati 'ely wide resiliently yieldable legs Q5, the outer sideI edgesof which arel longitudinally curved to cooperate with the (,:uiw'ed sections 17d of the base walls of the `gnjooves in the shaft end. It will be understood that when ythisI key is inserted, said outer edges of the legs 25 engage the pa"- allol end ]')ortions l7c of the groove walls, and as the curved edges of said legs ride against said walls, thc legs are forced inwardly towards each other until the key if; inserted when they expand to their normal positions and interlock with the sections 17 of the grooves to hold the split end of the s iaft expanded against the vz lis of the rollback bore.

Fig. lfl shows another possible construetion in which the grooves 17@ are relatively wide and do not extend entirely the 1 tti;

opposed faces of the shaft portions 14.

The base walls of the grooves at the entrances thereof extend for a short distance in pa 'allel relation to eeh other and are then curved as at 171'`v aid curved sections terminating upon the inner face of the shaft portion 1l. In this ease, the lorltinp; lv'ey is in the form of a me al disc ill", the diameter of which is eater than the dir-tance between the base walls of the grooves t7" al the eutrai thereof. Thus as this dise is forced under pressure into said grooves the parts ll of the shaft are expanded. said dise being finally seated against the Curved wall seetions 17 whereby the dise is held or retained in its lockingposition to maint-.zin the frictional pressure of the shaft end with the walls of the rollback bore.

From the foregoing desrripiion eonsidered in ronneriion with th areompanyinp; drawiro's the rons'lrmiion. manner of us'.` and var. :nlvantages of the several illusii-il ed embodimentsI of my invention will be rlear .nnlerstood. ll will be seen that l devised very simple means whereby the .sha l'l may be securely locked in ronneelion with (he rolihaeli and which owereomes possible olrieitioini to the means whirh l have heretofore devised for this purpose as shown in the is ned iiatents above identified. Any one of the several expaiulinpand lor-hing mrans for eonnecting the shaft rnd with th l rollbaeh een be very easily and (prickly applied with or without the use of :t common lool.

I have herein disclosed several dili'erent ruetural forms of the shaft and expanding' l loelringr liev members, but it will be unoerstood that it is also possible to devise various other alternative formi-i of this feature of my present improveme its. and l :woordingly reserve the privilege of adopting" all such legitimate changes therein as well as in the partieular form or eonstruetion of the handle shaft, itself. as may he fairly invorporated in the spirit and .sr-ope of the invention as claimed.
