Asshoiyn by Figs. l. 2, 3, and 4,.'of the annexed drawings. my nenv or improved printing machine consists of the frame A, eoustructedof eastfiron. ln suitable bearings'in the vtyvo upright side portions vof the tra-me of this machine. there is carried the axisB. of the printingr cylinder C. *.Upon

the'bars J, and K, the type holder L, is held by hand againstthe end O, of the type hold- .opening outward so as to insure the correct placing'of the type holder 4N, against the ends of any paii` ofthe bars J, or K.

The type cylinder C, has the greater part of its surface fitted with the bars. J, and

K,'\in order to receive such number of lines of .type as may be necessary for printingl any circular, letter or other document which y a machine of the kind constituting my present invention i's'inore especially adapted to print. Between the ends of that part' of the surface of the type cylinder C, wherein the 4types are carried, and as' more especially shown at Fig. 4, two rollers R, R, upon which 'portions of the printing ribbon S, are wound, are carried, one end of each of theserollers R, having a toothed pinion T,

'securely fastened thereon. yThe printing ribbonS, 'extends from one of the vprinting -rollers R, around and over the entire-portion ofthe surface of the types inthe print-- ing cylinder C, to the other printing ribbon roller R, so that when the type cylinder,

isset with type, the type or printing sur- Lface is completely covered over by. the inking ribbon S. `In the lower part of one side of the frame A, there is situated a circular toothed rack U, as shown in dotted lines in Fig. 3, and in end .elevation at Fig. 2. On that portion of the printing cylinder C, between tlie two recesses wherein the'inking ribbon rollers R, R, are carried, there is' contained a' portion more especially shown 1n section in Fig. 4, marked V,.whereon an electro-type, copper plate, or other engraved or printing surface, V, such as that constiyt-uting a letter 'head to be printed as the lieading'ofcirculars, letters, or analogous documents, is carried. This portion V, is remoyable and changeable as required from 'time totime, being fastened to the portion V, by nieans of screws or 'other convenient f 'attachment- V2, as showi'i at Fig.4 2. In the .contains printing ink indicated by hori-` upper ,"part .of the frame A, of the machine, there is carried the longitudinal ink well lV, Figs., 1, 8, and 4. Assh'cwn by Fig. 4, wherein the ink well iV, is in section., it

z ontal dotted lines, and with an opening in the bottom through which the strip of felt X, passes, and protrudes against the surfaceof the inking'vroller Y.l The strip of felt X, being retained inthe4 inking well lV, by means of the folding over .upon itself `of' itsau per part as shown in Fig. Il.. The

'esI

Width of'the opening through. which the strip of felt j passesfis 'narrow enough to prevent the stripof felt from falling through such opening, while allowing suiiicient freedoin ofthe holding of the felt to enable ink to pass from the well lV, through the felt Aas afeeder to the inking roller Y. The inking roller Y, is that part of the machine which applies ink to that partof the printing surface inarked'V, in Figs. 2', and

4, carried upon the portion V, ofthe print ing cylinder. The axis of the inking roller Y,-is carried in vertically slidable bearings Yin the upper ends of the standards of the fraine A, and they are pressed downward by means of spiral springs Z, acting upon the bearing blocks Y', so that the flanges a, one at each end of the inkiiig roller Y, are pressed down upon the cylindrical ends b, b, of the printing cylinder C, by which arrangement the surface of the cylinder Y, is kept out of contact with the `printing ribbon S, during the passage of that portion of the rotation of the printing cylinder G,- and inking ribbon S, beneath the inking roller Y. The pressure of the l springs Z, is obtained by means -of the plate Z', compressing the springs Z, by means of the screws Z2, screwed into tapped holes in I the upper ends of the framing A. This separation of 'the inking roller Y, from the surface S, of the inking ribbon during such portion of the rotation of the printing -cylinder, is shown in diagram Figs. 7, and 9, whileV when that portion V, which contains `the letter head, .or equivalent electro-type.

wood cut or engraved matter being situated S, carried upon rollers R. R, when passing between the two ends` of the inking ribbon -V beneath .the inking roller Y` enablesthe inking roller Y, to be pressed down into the re-,`

cesses wherein theinking ribbon rollers 'R,

are carried, and to make contact of the in'king surface of the roller Y, with that pori-.;v tion of the surface V, whereon the letter head, bill head or other. permanent part of the printing surface is contained, by which arrangement thisA portion V. of the printing surface receives its ink'dir'ect from the roller Y, and all the other part of the surface to be prin'ted receives its ink from the inking ribbon S. Beneath the printingcylinder C, and also beneath the inking ribbon S, carried upon the printing cylinder C. there is situated the adjustable pressure roller c, carriedupon a shaftd, held in adthe printing cylinder rotates, catches the vprinting cylinder C, and so as to cause'the,

lowerv edge ofthe paper andpresses itfupon the pressure A roller c, whenl as the continued rotating of the printing Cylinder C, proceeds,

the paper is drawn `from off the platform,

table or support g., and discharged over they top, of the pressure roller c, with 'the.print, ing which it has received 'from the inking ribbon S, upon the types in the cylinder C, being pressed upon itsupper surface, and each sheet of paper thus printed is successively `discharged lfrom between the printing ribbon, andthe pressure roller c, in the direction indicated bythe sheet of paper e', in Fig. 4,. As duringthe continuanceof the printing operations hereinbefore described, the inking ribbon S, becomes wound off oneof 4the inking, ribbon rollers R, andvon lto, the other'inking ribbon' roller R, each time that one vof the pinions T, engages with the toothed rack U, it, follows, that the -continuance'ot1 the printing operation will roll the printing .ribbon S, ott one of the rollers R, and wind it on to the opposite n roller. When this condition of the printing ribbon S, has been reached it. becomes'necessary. in order to continue the printing operations, that the winding of the-printnig ribbon shall -take place in the reverse direction,vthat is to say,l that itshall be` wound oitl that roller R, upon which it has accuinu- 'lated, and be correspondingly wound 'upon theotlier roller R, from which it has been drawn.J To enable this reversing' ot the direction of winding of theI inking ribbonlS,

toitake place, each of the pinions T, anc

are mounted slidably upon one endet the axis y', which is preferably made square as shown at Fig. 3, and in enlarged detail at Fig. 6, In Fig. 6, the part marked 7e, represents.in section thatiportion of one end oi' theprinting cylinder -wlierein the toot-hed pinion .,r fastened slidably upon the square end of the inking ribbon roller is carried. When the pinion T, of one of the printing ribbon rollers R, has slid outward uponthe square portion of the axis j, ot that inking ribbon roller, then it is in such position as to gear with the toothed rack U, at each rotation ot' the printing cylinder C, and the pinion T, which is winding oii' the inking ribbon S, from one of the inking ribbon rollers R, is pulled vout Vinto the position Vshown in Figs. l., i?, and 6, so as to gear with the cui-fed toothed quadrant U, at each rotation of.. the printing cylidner C, until the ribbon S, is wound olif one of the inking ribbon rollers R, on to the other inkiiig ribbon roller R, when tn o, pinion T, which has been last .in operation with the toothed quadrant U,

As shown by Figs. l, and 2, of the draw ingsthe types land space blocks are held in' between the strips' J, and K, by means of plugs of india rubber, or other sufficiently hard and elastic material, pressed into those por-tions of the 'spaces'beyond the end of each row Aof type, and. in Fig. 2, the sheetvof paper z', is shown as being discharged from between the pressure roller c, and the inking l:with what is known as single spacino, double u l u n o u v spacing and treble spacing in-typewrit-ing,
