J. M1 FRAZ. UNE DUSTER FOR TYPE-WRITER PLATENS. WPHC/more mm FEB. 18. 1914.
This .invention relates to typewriting, adding or analogous `machines includin a circumferntially movablel or adjusta le roller or platen. Among the objects Aof thein'vention isvto provide an attachment adapted to'be added ,to any' usual or conventional forngrV ofv typewriting machine to which the attachment is applicable forthe purpose of adjusting the platen wo"r., roller to any desired extentless thanfthefullspace adjustment. Morespecifically stated, I provide an attachrnent for the end of the platen shaft i providing, in connection with the lusual ratchetwheeh a, special finger wheel having connection 'with the shaft independent of the vusual' 'ngerf wheel whereby the platen maybe rotated to any extent independently of-theusual means for lrotating it and without` .interfering infany manner. with the usualstep-by-step line adjustment. The foregoing 'and other objectsofthe invention 'will hereinafter be'more fully described claimed" and" illustrated in the drawings forming a partv ofulthisspe'cification in which lile characters of` reference indicate corresponding. parts in all the views, a nd in WhichpT l ":Figure 1 is an elevationvof'one end of' a platen showing Lmy inventionapplied there- 40 to, parts,being'ixrelevationl and other `parts lin section; Fig. 2 is a Similar; view but with the Y new i attachment lsubstantially'A inl central flongifudinase eqn.; and rigs; and 5 are vertical-tl-Ilsfle sections on corresponding linesof'Fig. L c

however,V is Vj'ournalecl 'loosely upon' the Shaft 11 and is secured 'to a special' 'formfof finger wheel casing-'15'which, through certainpeculiar connecting' means, 'serves to 'rotate lthe platen in' either" direction in afinannercorree 'm Asponding to the usual practice. lVithin the casin l'5` is a l'loatinggbr otatable frame or spider llhavifg afl-'rub se-z cured as by means of a set screw 17ito1the lendof thc shaft 11.'

A positive rotation'of the casing $5* lf'through the. ratchet Wheel and Worm wheel connections with the spider'will-cause a corresponding rotation ofthe platen due f tothewellflrnown interlocking featurefbe tw'een'fva single'pitch Worin andfi l i wheel'. j il 4 For the purposel ofdelicate adjustment of the platen so as to bring the"paper-into finer line adjustments than can readily beob` videV 'means whereby the spider nay be '-ro'- tate'd independently of thef'ra'tcliet wheel and its finger casing 15, and since theusual reta ining means' for the ratchet wheel 'rel mains' functional to hold' tlieratche't wheel and lthe worm 'wheell station'aryf 'the lspider maybe casedfto Vcreep orf"rotate slowly around' the axis ofthe-ratchet"wlieel'and cause" 'through 'the s'et screw -1.f *a* corresponding slow rotation of theifplatenso as to effect the desired delicate `adjustment of the paper.

' float with the spider aroundl the axis of the shaft 11 during the rotation-.of the knob 20.
.At-25 I show a shaft journaled in bearings 26 on the opposite, or inner side ofthe head'l of the spiderffromjhe worm 17. Said wormand shaft 25' carry pinions 28 meshing. with `each other whereby the'\worm may driven from the shaft 25 and by means of. bevel: gears 29 from the countershaft 24;` Two- jheads 16 and 16 of the spidenai'e 'maintainediin proper spaced relation-by meansofstay rods 30..
'I hef arrangement o f gearing between the knob 20.and the worin wheel is such thata rotation of the knob 20 independently of the ratchet Wheel 14 will cause a rotation ofthejplaten in .precisely the same direction as if'the main finger wheel 15 were op= erated but at a slower speed.
The invention herein "disclosed is of Aa simple',..= compact and .comparatively cheap natnreland. -ma'y readily be 'applied but with slight -mo'dilicationto any known form of typ'ewriting' machine or othermachine havingan' adlustable roller.
