In Figs. 1,2, 3, 4, and 5, the horizontal base portion is marked A, andl it is shown asy consisting of a ilat plate of cast 'iron or equivalent material, Whose upper surface is planed true and level. Upon this surface 8o either the types B, su'ch as shown at Figs; 2,

3, and 5, are carried in4 the`galley, or chase: whose side and end portions are marked O, in Figs. 2, 3, and 5, and wherein the types B, as shown more especially at' Figs. 2, 3, and 5, 85

are retained operatively by being held in the chase C, by reason of the furniture of the galley D, being forced in the well known manner against the type slips E, and types B, by the particularly'shown at'Figs. 2, and 3, being o erated by the attendant of the machine' in' p acing the toothed key which being so well understood is not shown in the drawings, in between the toothed spaces H, and turning the toothed key by its handle so as to^causethe wedge surfaces F, and G, to slide upon each other and thereby pressr the furniture D, against the type slips E, and types B, in the manner' commonly practiced for holding type in a chase. The-frame consisting ofthe chase C, and its contents, the furniture D, type slips E, 'and types B,-fres't on the iiat bottom of the base A. "i i When instead of printing from a surface of type which maybe either type, in style and character corresponding to that commonly used in typewriting machines, or which may be of other kinds of type, such as type in imitation of script, or of other form or character, or when copies of drawings, pictorial representations or maps are to be made in the machine constituting my invention, then, instead of using the galley or chase and its equipment as hereinbcfore described; a block of material such as type-imstal, or other metal, a wood or metal engraving, electrotype, or other block containing on its upper surface the drawing, map, or representation to be reproduced by a printing operation, is carried.

At each of the sides of the base A, is a space J, extendingthroughout the entire length of the base A. ln the under face of the rail Alt there is cut a V-shaped groove l, as shown more especially in transverse section in Fig. 5, the purpose of which will be hereinafter explained.

The carriage of my new or improved machine, consists of the frame ll, which consists of a single casting as shown in the drawings. 'lhe lower part of each end of the frame L, is I )ifurcated as show n at Figs. l, 2, and 3, more especially, and at the end of each bifurcated arm there is carried the stud 0,2 upon the inner end of which there is also carried rotativelj', the. roller l, whose form and construction is more especially shown at "ig, 5. These rollers l, press up into and against the surface of the grooves li, and conjointly with ,the influence of the elastic rolling surfaces of the ends S, of the impression roller Q, maintain the carriage and impression roller Q, in proper operative relationship with the base A, in such manner that the carriage and the parts of the mechanism carried thereby cannot be dislocated from their proper relationship to antl with the base A, either accidentally, er in any other manner than by taking asunder some of the parts for admitting of the separation when required, of the carriage and its connections on the base A, of the niachine.

At the upper part of the base A, at the sides thereof, and of the requisite height or depth there are two parallel portions ltr, li, which while providing for the admission ol' the chase or galley, or type holder, or block, having a printing surface at the proper level below t-he impression roller Q, also provide, at the top surfaces of these .portions lt, level faces upon which ythe`two ends S, S, of the impression roller roll.l 'l`he diamet er of the ends S, S,`ol` the impression roller Q, is preferably greater than the diameter of the intel'- mediate portion of the impression roller, and being of elastic material, such as vulcanized india rubber, these ends S, S, when rotated as hereinafter described, roll-smoothly upon the upper surfaces of the 4praised portions lt, lt, and provide elasticfslightly yielding l l l 1 l i l l l action between the cooperating parts of the machine,l

The impression roller Q, is carried upon the axis 'l`, one end of which is formed square as shown at U', Fig. 5, in order to receive thereon the crank handle. tl, Figs. l 3, and 4, which on being rotated by the hand ofthe operator of the machine, causes the carriage and the impression roller to be traversed from end to end ofthe base A. 'l`hei1npression roller Q, in this case is fastened 'rigidly to the shaft rl, so that as the shaft l, is rotated, the roller Q, is correspondingly ro tated in either direction.

rlo more ell'ectivcly regulate the elastic pressure of the ends S, S, of the impression roller Q, upon the top surfaces ol the portions li, lt, the carriage li, is provided with carrier blocks V, which are capable of vertical adjustment, that is to say, upwards and downwards in the. parallel openings V, in the frames li, by means of the set screws WV, V, :is shown at Figs. 1,-2, 3, 4, 5, 6, and 7.y 'lhe set screws 1W, W, at their lower ends bear upon the blocks V, in positive relationship with cach block V, from which arrangement it results, that by turning the set screws lV, in either direction., not only is the .pressure of the end portions S, S, of the inipression roller upon the parts li, regulated so as to adjust the elastic action of the end portions S, S, of the impression roller Q, upon the. parts lt, the rollers P, P, into their grooves K, K, with any required degree of elasticity for the eflcient operation of the machine,-but this arrangement also enables the pressure of the intermediate part of the impression roller Q, upon the paper, the type ribbon, and the printing surface. from which the copies or impressions are to be taken, to be regulated from time to time with the utmost nicet'y of adjustment.

-At each end of the base A,the1e are rccesses Y', and Y2, respectively, preferably inclined as shown at Figs. l, and 2. ln each pair of these recesses there are situated the l-)earings of the rollers to which the printing ribbon is attached, and by which the printinf-I ribbon is ODG-rated as hereinafter described. Each ribbon holder is provided with a ratchet wheel cl, at one of its ends which is 'lirmly fastened to one end of each ribbon roller, and the frame l1, of the carriage at the sante side of the machine whereat the ratchet. wheel d, 1s situated, arries pivoted to each bllurcated arm the pawls c, and

f, respectively, as shown at Figs. 1, and 3.

When the carriage and impression roller of the machine are moved towards either end of thel base A, then cit her the pawl c, or the pawl f, engages willi one or the other oll the ratchet wheels d, (l, according to the direction in which the carriage and impression roller ol' the machine are being operated, and since each paul c, or j, makes contact with one or the other of the ratchet wheels d, before the carriage arrives at the termination of its travel, the `further movement of the carriage after the contact of its pawl e, or f, with either of the ratchet wheels d, d, causes the rotation of one or the other of the ratchet throu h a corresponding distance off one of the ri bon carrying rollers, and upon, or on, to the other ribbon carrying roller. arrangement a fresh surface of printing ribbon is presented to the typeior other printing surface, at each traverse of the carriage 'and impression roller, and anteriorly to making the next succeeding impression or printing operation; the rotation of one ribbon roller Vbeing about twice that of the other ribbon roller.

This variation in the amount of rotation of the two inking rollers results from di'erent lengths of the pawls e, f, which may be jof equal lengths, or may be of different lengths, and when of different lengths one of' these pawls operates upon one of the ratchet wheels d, for a longer timethan the other pawloperates upon the other ratchet wheel d.

To insure the requisite length o f movement of the ribbon rollers for producing the requisite movement of the ribbon g, shall be capable of adjustment, the pawls e, and

while carried pivotally upon the pinsh,

- rest upon the top surface of one of the guides or rails R, as shown at Figs. 1,` and 3, until reaching .the ratchet wheels d, one on the end of each ribbon roller, when the pawls respectively engage with the ratchet wheels d, and rotate them together-with each ribbon roller alternately, so as to wind off one of the ribbon rollers and on to the other ribbon roller a length of printing ribbon adequate to supply a fresh surface of such .ribbon at each printing operation'.

Instead of operating the machine hereinbefore described by turning a crank handle U, as described, the machine may be operated by the attendant applying his hand to the top of the carriage L, and by pushing or pulling the carriage horizontally, causing it and the impression roller to make the successive journeys or traverses` upon the base of the machine .which have already been described as being performed by turning the crank handle U. When the machine is operated by pushing or pulling the carriage or impression roller, then the crank handle U, may be taken ofi" the axis T, of the machine, but it is not necessary to remove the crank handleU, in order to operate` the machine by -the lattendant pushing Aand pulling upon the bridgeof theI carriage L. Instead of using theV-shaped grooves K,

By thisV K, in the bottom of the guides R, R, as shown at Figs..1, 2, and 5, the under parts of the guides R, may be c structed with 'a rectangular groove as sldidwn at Fig. 7, in which case insteadof using the V-shaped rollers P, P, acylindrical roller'm, carried upon the stud n, fixed in the lower art of the frame L, may be substituted.

nstead of using.'

either of the/rollers P, P, as in Fig. 5, .or the roller m, as in Fig. 7, these rollers may be dispensed with, in which case the lower part of the carriage L, is formed with an inwardly projecting lug '12, preferably of dovetailed form fitting into a dovetailed groove in the longitudinal sides of the base A.

4Instead of so constructing the impressionV roller Q, that it is firmly iixedV upon 1ts shaft T, so that the shaft T, and the impression roller Q, rotate as one piece or detail of my improved machine, the roller Q, and the end portions S, S, may be constructed separately as shown at Fig. 7, in which case the end ortions S, S', are keyed or otherwise firmly' ed to the axle T, While the impression roller Q, has fastened into its ends a bushing q, which enables the imqpression roller Q, to rotate upon the axle I desire it to be understood that when using my new or improved machinefor printing copies of drawings, maps, landscapes, pictures, etc., or 'when used for making copies of representations wherein there are not parallel lines, such as the lines of type in typewriting,

or the lines writing in ordlnary manuscri t, or the lines of engraving, such as is used in t e production of public state and national documents, wills, and otherpapers written by hand, v

or copies of copper or'steel engravings wherein lines of writin or literary signs are placed in parallel, that do not in such cases use the pawls and ratchets for regulating the motion of the inking ribbon carried upon-the winding rollers of my machine, but instead thereof, when a larger surface is to be printed at each successive impression making or printving operation' of a drawing, map, icture, or other largp continuous surface, t vat I then remove t e pawl and ratchet gearing from my machine and wind by the attendant applying his or her hand to one of the inking ribbon rollers a new surface of inking ribbon of sufficient length corresponding to such surface for each such impression when necessary to'be printed from.

The bed A, of the machine, is provided with four projecting iris X, X, X, X,'wliich check the travel of t e'fcarriage L, in either direction. A'

I For the purpose of maintaining suiieient frictional resistance upon the bearings of the inking' ribbon rollers, there is pressed into vthe upper part of the bearings Y', and Y2, a corl respondingly shaped block of india rubber, as'shown at Ya, 1n Figs. 1,-and 2, which by reason of its elasticity not only holds in place,

bearing Y', and. Y@

When Pressed into the upper part of each l but also acts as an elastic drag upon the nklng ribbon rollers.
