To all who-m, it moy webcam:

Be it known that l, Homer lli. loonivnnn, ecitizen of the United States, residing et Bristol, county of Hertford, State of' Corn necticut, lieve invented :i certain newr and useful Shaft-Coupling, of which the follow ing is e full, cle-er, and exact description, suoli es will enable others skilled in the-art to which itepperteins to ineke enel use tlie seme, reference being had to the :ieconipenying drawings, forming peri; of this speci ication..

My invention reletes to slniit couplings, my object being to produce"econnling oi simple structure leaving positive driving connection between the coupling' members and yet possessing reet freedonl of movement of seid members with respect to einen other. y

To this end, and also to improve generally upon devices of the character inclicetelli, my invention consists in the various matters hereinafter described and claimed.

In the accompanying drawings, Figure is e perspective View, partly' in section; Fig. 2 is e Ilongitudinal .sectional elevation on about the line ,L2-2 of 3; and Fig 3 'is e transverse sectional elevation on about 'the line 3&3 of Fig. 2.

in the embodiment of my invention .illus-.- tinted in the aceoinpenying drawings A nini B indicate the shaft sections to connected, end 1 and 2 indicate the respective coupiing members. Eeclioi said coupling members is orlrc7 having e 'need from 'which 'the ngers o the forks extend9 the fingers upon the coupling member l lacing marked 4, enel those upon tlie coupling inen'ioer i), being marked The fingers or' enclin coupling member ere dieinetriceliy opposite euch other end, when the parte ere assembled, ere engularly disposed with respect to 'the iin gers upon the other coupling member, so that the lingers oit one sitio member ere et about right :ingles te these of the other seid member. The fingers ere relatively oroecl e* eccive liet/Ween there e central driving l/ocii 3 which is rectangular in cross-section.

in tlie structure shown, the lingers ere of less Wifltli than Vare the feces of the lolocl: which they engage. Furthermore., the iingere are disconnected 'from the block, e1 ci.,

they lieve no pivots or the like coi'inectinr them te the block, so tout eocl'i inger is freely movable with inspect to the lalocln When the parte are m-seinlalcil upon their sliei't sections, the distance between the inner feces of the liceale i is loss than the length oi tlie biock ll, es Fig. 2. "lliereform this coupling; presents great freedom oi movement. it being possible 'oi the s .ett sections to more longitudinally tower-cl and away from each other, to sliii't in lines transverse ee-*cli other, und to rock with respect to enel). otliexx Neverthe less, the lolock forms e positive (l'ivingr connection between 'the coupling members F'l end Preferably each iinger lies e pri'ijecting portion Z which extends iiey'onfl the block :incl overlaps the lieecl oit tlie ether coupling; section. This prevents accidentel separation of the coupling members when the parts are assembled upon the sliefft sections, because transverse movement oit eeco coupling inembei' is limited by the :lect oil'ljits lieecl 2l coming into contact with the overlegging pox tion of e inger of 'the other coupling inemlier.

ln the structure here shown the coupling member i connected to its shaft section Si ey e threaded enti 8 upon the slieft scction recei ing at nut 9, seirl tlniezuleal entl :zml nut exieiiflixlgg; into tlio space between lille tinoi" the coupling nlcnil'ers. this event, the centr-il driving block i3 man no previrled with e central o'leningg it to receive the seid parte lanci is ilnstreted in lli'uniiestly, the present, coupling `is ineirl pensively mede enl easily assembled. Nevertheless, 1giositive driving is insured oe-I tween the f :onplionggf members and, et the seine time, suoli coupling members neve greet frceelom of movement vith respect to eeclx other. `lllnrtnermore7 notwitnstending' the simplicity of the strnctnre, scciflei'ltel scpnretion of the coupling incmliers by excessive sidevvise'movement is rendered infposn sible.

l. A sliet coupling comprisinfr e central eioclr, e :forlreai coupling member having its upon opposite sides of seid block and disconnected therefrom with respect to lootio longitudinal end litter-:fil movement whereby seid .fingers ere freely movel'ile longitudinally anni leterelly with Yrespect to seid liloclra anni seconci forked coupling; member c lievito its ingers upon opposite sides of seid y block, a' forked couplln lngere upon opposite si 10 block and engularly disposed with respect to said iret mentioned lngere, seid second mentioned fingers also being disconnected from said block. with respect to both longitudinal and lateral movement; eubetantally described.

2. A shaft coupling comprising a. centraal member having its es el Sadblock and movable laterally across the seme, and n Second forked coupling member having its lingers upon opposite sides of said block and' angularly disposed with respect to said rstmentioned fingers, said Second mentioned fin gers also Vbeing movable laterally across Said block, the sind fingers upon each of said coupling members extendingv beyond said block and overlapping the ling member; vsubstmntielly es described.

3. A shaft coupling comprising e central they are freely movable block, and forked coupling members each havin-fg lingers upon opposite sides ofsaid block, the Engers upon one said coupling rnenibe'r being singularly disposed with re speel; to the other seid lingers, said lingers' of each said coupling member being disconnected from said block with respect to both longitudinal and lateral movement, whereby 'longitudinally and laterally with respect thereto, being of less Width. than said block, and extending beyond. said blockand overlapping the other said coupling member; substentlelly as deP scribed. f
