%'he forward end of the shaft has a spiral: gear fixed thereon and intermesh: ing with .a second spiral gear31 fixed upon the lower end of 'a vertical shaft 32 supported in bearings 33, 34 and llavi a worm 35 slidable uporits upper end aiid splined thereto, sueh -ivorm intermeshing with a worm wheel 36 mounted rigidly on the shaft of the impression roller; The worm is held yieldingly against vertical -di spla'cen1ent .in

an upward direction by a spring 3,8,th'e object being to enable theworm and wormwheel to remain constantly in engagement while the slidable relation of the worm and its shaftpermits difi'erent di impression roller to be accommodated. As,

for instance-each time the blankets are-put on freshthey'p after they-have been used fora while, and the varying diameter of the cylinder due to diflerent thicknesses of the printingplates.

40 The springajs held by the ,washer '39 and nut.

The. main shaft 20 is driven by a motor 60,'the shaft 61- of which has-a pinion 62 fixed thereon and intermeshing with a spur 5 gear 63 fixed upon thesaid m'ainsha-t't so.

In order to efleetively and economically operate a printing 'machine containing the cylinder with its intermittently successively actuated peri herul printing, irre'nilwr a wiper is prori ed capable of bring conl lined within theframe beneath thee-yli rnler and adapted to perform its'function and shift during the intel'missi'dns between the passage of the saiddnembe'rs asfoll'ow's; horizontaliiigarriage .eapah h; otbe'in ,dismembered-i b be nserted or reiiioved from between the legsof' the nun-hinegmeans for causing this (-arriage to 1r" vol ehntinuously within the confined space, and intermiteo tently actuated wipingdevices suspended from the carriage and acting upon the printmg members as they passjf." l I The carriage cons sts of an bb'lon'g bodyframe having bolted thereto transverse 65 end bars 71 widened 'atl'the'middle 72 and Jfurtherallu ed to. A frame 'for the wi and extendingmechanism is suspend'ed from thecarriage from end to end of the roller, the surface over the wiping 1n vertical extensions'53 of the side frame,

This wiping material is wound on a feed roller, upon which a brake I acts; and is caused to moveintermittently member by an intermittently operated take-uproller, allof these rollers being journaled' in the hanging frame. The feed roller is indicated at .78 0

in a square arbor 79 i one end terminating and the opposite end having mounted rigidly thereon a brake-wheel 179 retarded-by 'a pair of brake sho'es or jaws 180 on levers 181 adjusted bya right-and-left-hand screw f 182 by which the tension of the webcan be minutely adjusted' The web passes from this feed roller-around th'e'bar 76 and over the wiping member to the-take-up roller-indicated .at 183 and supported on'a pair-of rollers 184 185intermittently rotated bye rocker-bar-186 fulcrnn1ed on the roller 184 andearryingan actuating pawl 1'87 engaging a' -ratchet wheel mountedwigidly on this roller, a detentpawlf'188 preventing 'retrograderotation of the roller, while a pair of spur gears 189, 190'mounted on the'respective rollers and an idler- 191 "transmit r0 tation froih -the roller 184 to'the roller 185. The web passes around'the guide roller 193 and the increasing 'diarneterof the take-up i'oller'islaccommodatcd by its hearing which is vertically elongated.

Thewiping member is carried within the frame of the carriage-and consists of a yieldinglysupported and verticallyadjust-' able table 200 haying bored lateral flanges 201 and a wooden block 202 covering the top thereof and in tum covered by a felt pad 203and leather cover 204. edges of the leather are clamped between pairs'ot bars 205 206 to which are connected drawing screws 207 projecting through the borings in the flanges 201. and-having butter-fly nuts 208 scrmved thereon for draw-.115 ing the same through the flanges and tightening the cover. This table issupported through the medium of springs 20.)v on a bar 210 secured at its ends to the sides 75 of the suspended frame and serving the 1 double purpose of a tie-brace'for this frame.

The springs are'guided and the normal. height of thetable and tension otthe springs adjusted by bolts 212 and nuts 213 while a pail-of plates 215 are forked at to engage and look the nuts and are held in place by screws 216 and thumb nuts 217.
