THOMAS BARTHOLQMEW. OF NEWARK, OHM`v SPECIFICATIQN forming part of Letters Patent No; 531,088, dated December 18,'1894.

A Application led December 12,'1892. Serial No.454,969. (No model.) v I To all whom it may concern:

Beit known that I, THOMAS BARTHOLOMEW, a citizen of the United States,'res`iding at NeW-; ark, inthe county of Licking'and Stateof- Ohio, haveinvented a certain new and useful Improvement in Printing-Machines, of which the followingisa'speciiication. .Y L v.

My invention relates totheimprovement of printing machines and has particular relation to machines or devices for printing dodgers, hand bills, dac.

The objects of my invention are to provide a superior machine of this class of improved construction and arrangement of parts; to so construct said machineas to provide simple and reliable means for printing on one or both sides of a continuous. sheet of paper and cut the same into the desired lengths when so printed; to construct my machine in a reliable and inexpensive manner and produce other improvements which will be more speciically pointed out hereinafter. These objects I accomplish in the manner illustrated in the accompanying drawings, in which- Figure l is a side elevation of my improved machine. Fig. 2 is a plan view thereof with the paper withdrawn from the rolls. Fig. 3 is an end view. Fig. 4 is a central section on line :c a: of Fig. l. Fig. 5 is a face view of the type or printing roller. Fig. 6 isa view of .a portion of one end of said roller and Fig. 7 is a sectional view through a portionof one end of the roller. A

Similar letters refer to similar parts th roughout the several views.

a represents a suitable oblong stand or base from which rise on opposite sides and at opposite points metallic frames or supporting standards a. The upper and enlarged end portion of each of these standards has formed therewith oppositely located bearinglugs a2 which project forwardly and rearwardly as shown. Each of these lugsy is provided with therollerb at each endthereof is a band b2, said band having its inner yportion raised slightlyfrom the'roller surface to provide a circular socket or recess between the roller and band. These bands are provided at opposite points with incisionsb4 in their inner edges, said incisions being adaptedto receive the tongue ends b3 of horizontal typeholding plates b5 and admitting of the latter being forced to the desired position on the roller and being retainedthereon by said bands.

In order to limit the movement of the type holding plates on the roller, I provide suitable projections bs on the periphery of said roller against which the type plates may lodge.-` A

As a further means of 4retaining the type plates in position, I pro'vide'stop strips 57, the latter having their outer edges retained beneath the inner portions of the bands b2 and having their flanged or shouldered ends bs bearing against the last inserted type plate b5. The body of each of the insertible type plates is preferably of the channel shape shown and each of said plates is adapted to retain between its flanges raised faced type orprinting blocks of rubber or similar material as indicated at c. At a distance from the group of type plates I provide on the roller b a spacing bar or projection Z915 preferably of a yielding material which is equal in height to the type above mentioned.

Within` the slots a3 of the lugs a? bear the spindles d of ink rollers d', the latter having a suitable covering of pliable composition or material d2. The ends of both these ink-roller spindles are as shown at d3 connected with the frame work of the standards at inner points by means of contractile coiled springs. d4

represents cams which project from the ends` of the roller b past the periphery of the late* TheV ter at points opposite the spacing bar. curved outwardly projecting portions of these cams are as hereinafter shown adapted to come into contact with, the ends of `the ink vrollers and prevent the latter coming into contact with the spacing bar. d5 represent ink pad boxes .or plates which are supported preferably upon spring wires or rods d6 the latter extending from one standard a to the other and serving to press the inking pads or material 17, contained in the boxes, into contact with the ink rollers.

.ICO

e represents an upper and smaller roller, the latter having its end spindles mounted in the slots a of the lugs a4 said roller e having its periphery in close proximity to the 5 roller b.

Supported upon rearwardly projecting shoulders e of the standards a', are the ends of a transverse feed-board e2, from the end portions of which rise rearwardly inclined Io bracket arms es. ln the upper ends of these bracket arms are journaled the spindles e4 of a roller e5, the latter having normally wound thereon a coil or roll of paper e,

e7 represents a lower roller corresponding r 5 in size with the upper roller e, said lower roller being journaled in the lower portions of the standards a', as shown.

eH represents a binding bar having its rearwardly turned end portions pivotally con- 2 o nected with the inner sides of the brackets e or other suitable framework. This pivoted bar is, by means of a suitable spring e, one end of which is secured--to the feed board and the remainin g end of which bears on the bar es, made z 5 to press normally against the upper side of the feed board. el@ represents a spring finger which projects from the bar e8 near one end thereof and extends between the rollers e and b. This spring finger normally presses downward and when the type plates are passing beneath the upper roller through the rotation of the roller b, said spring finger is brought into contact with suitable filling blocks or pieces e in the corresponding ends of said type plates 3 5 b5. The result of this contact is that said spring finger is temporarily raised upward within a peripheral groove el"l in the roller e.

Supported from the forward sides of the standards a opposite the upper portion of the 4o lower roller elis apaper feed board fand upon said feed board is pivotally supported orjournaled a spring actuated binding bar f which corresponds .with the upper binding bar es. This lower binding bar is also provided with a 4 5 spring tongue projection fa which, as shown, projects between the rollers b and e7 and which is adapted bycontact with theelevating blocks e of the type plates to be pressed into a groove f4 in the lower roller e?. As shown at f 5, l pro- 5o vide the bars e8 and f with outwardly projecting handle pieces.

f 6 represents tension screws one of which, as shown passes through an ear f 7which projects outwardly from the lug a4 on each side of the machine. This tension screw has rigidly connected with its upper end a head f8 in which the outer end of the spindle of the upper roller e is journaled. Upon each of the screws f6 beneath the head f8 and bearing upon the ear 6o or shoulderf7 is an adjusting nutfg. Upon the lower end of each of the screws f 6 is a nut f10 and between the latter and the under side of the earf7 said screw is surrounded by coil spring f 11.

Passing through an ear g projecting from the lower portion of each of the standards a in vertical alignment with the ear f7, is an adj usting screw g which as prescribed for said screw f6 is provided with an end nut g2, a coil spring g3 and an adjusting nut g4, and a head g5, the latter forming a journal bearing for the outer end of thelower roller spindle. Upon one of the outer projecting ends of the central roll spindle b' is mounted as shown at h, a cam disk, said cam-dish having an inwardly and outwardly approaching portion h h2.

i represents a transverse cutting block which is supported uponthe face or table a at a point in rear of the standards a as shown. This cutting block is as indicated at i2 pro vided with end plates, thelower extremities of which are bent inward to form lips t3, which project beneath the table top edges, as shown. Said lips serve to perform the office of guides when said block is moved forward or backward for the purpose hereinafter described. The blocki' has its central portion provided near its upper side with a suitable paper delivery plate i, the latter having its free end resting upon a transverse delivery bar 7c which connects the standards a' in rear of the upper portion of the lower roller.

7c represents a sliding bar which is arranged centrally in suitable keepers 7a2 and upon the upper side of the table top and which is adapted t0 slide longitudinally thereon. One end of this bar is connected, as shown, with the cutting block t'.

Upon the upper side of the cutting block and extending in the direction of the length of the latter and adjacent to the outer side thereof is a raised bar or elongated keeper m.

fm represents a metallic blade or bar which is secured to the outer face of the cutting block adjacent to the upper side thereof, said blade or bar having one of its ends projecting outwardly, as shown at m2. This outwardly projecting end of the blade m forms a journal bearing for a horizontal knife rod m3, the latter having its forward portion journaled in a suitable bracket arm n which projects out wardly from one of the standards a.

o represents an operating finger, one end of which is adjustably secured by means of a set screw o upon theknife rod m3. The upper end of the linger o' is notched or bifurcated to embrace the edges of the cam disk h, as shown.

Upon the rear end of the knife rod m3 is mounted a knife blade or cutter-bar s, the latter being adapted to shear against the outer side of the fixed blade m. The knife blade is yieldingly retained against the blade m by means of a coiled spring s which surrounds the outer projectingend of the knife blade and the outer end of which bears against au adjusting nut S5 on said rod extension.

Rising from the forward end of the table or machine base is a frame consisting of a vertical standard t from which project outward, and at right angles therewith across the end of the table, arms t the latter being preferably provided with longitudinal slots t2.

The method of utilizing my improved printing machine and the means of operating the IOC IIO

saine, are as follows; It being desired topri'nt and produce dodgers, circulars or other similar printed papers, the paper from which the same are to be formed is rst wound upon After passing between these rollers the strip Vis continued outwardly over or through the slot in the upper frame arm t', from which point it is dropped downward below the lower frame arm t where it is turned to form a twisted loop indicated at t5. From this loop the paper strip is passed through the slot of the lower frame arm t', thence between the lower and central rollers over the plate i6, be-

neath the keeper m ofthe cutting block and over the blade m.

The rotation of the roller b by the turning of a suitable crank handle u upon the spindle, must result as will readily-be seen in the rotation of the cam disk h. When the roller b has been suflicientlyturned tobring the faces of the rubber type in contact with the paper strip above said roller, it will be seen that the close proximity of said central and upper roller will result in the yielding type faces pressing the paper against the upper roller-fwhich must result in the rotation of the latter by the friction or contact thus caused.

In this manner itwill beseen that the type faces which have previously been, inked through their contact with thel spring actuated ink rollers, will produce the desired printedy impression upon the underside of the upper portion of the paper stri p. During this printing operationrthe paper is freed from the binding ac tionof the upper binding bar e8 owing to thevfact that the spring finger elo of said bar is pressed upward into the groove e12 of the upper roller, in the manner hereinbefore described. It will thus be seen that when the type have passed the printing point, said spring finger will resume its norf mal position, allowing the binding bar to drop downward upon the paper and press the latter against the board e?. The further rotation ofthe roller b will `result in the spacing bar or projection Z115 coming into contact with the paper strip between the central and lower rollers, and in said spacing strip by the frictional contact thus produced, imparting a partial rotation to the lowerroller and causing the paper to feed a short distance between the rollers. Owing to the fact that the cam projections d4 of the roller b are arranged opposite the spacing bar, it will be seen Vthat the contact of the outer curved surfaces of these cams with the inking rollers will result in said inking rollers being forced outward in their bearings sufciently to prevent their contact with the spacing bar, thus preventing the inking of said spacing bar as the latter passes the ink rollers. The group of type however having produced the impression on theunder sideof the upper portion of the paper strip as above described are by the continued rotation of the roller b brought into contact with'the inking roller and thus supplied with ink. When this group of type reaches a point immediately above the lower roller b7 it is evident that the upper side of the lower portion of the paper strip will be printed upon, and that the binding of the type between the central and lower rollers will result in the paper being fed toward the rear during said printing operation. During the time'that the group of type is between ther central and lower rollers, it will be seen that the spring finger f3 of the lower binding bar will as prescribed for the upper spring finger be pressed into the' groove f4 of the lower roller and the pressure of said lower binding bar upon the paper will be thus released temporarily.

From the above described method of print ing, it will be observed that the spacing bar acts after each impression of the type thus resulting in a separation of said impressions on the paper strip; and it will alsob'e seen that the impressions produced as above described may be thus made in opposite places on said strip.

The above described rotation of the cam disk h will result through the connection therewith of the operatingV finger o in said operating iingerbeing alternately rocked inward and outward, and in said rocking motion being contributed to the knife rod. 'As a result of this motion being contributed to ICO the knife rod it will be seen that the knife i wardand downward movement which move- Y ment will result in the lower sharpened edge of said blade acting with the blade m cutting the rearwardly `fed Yprinted strips into uniform lengths. In order to increase or decrease the distance between the upper roller and the printing roller for the purpose of increasing or decreasing the pressure upon the type, or for the purpose of equalizing`- said pressure, the nuts f may be turned upwardl or downward thus drawing said rollers closer together or increasing the distance between them.

For the purpose of producing a like adjustment between the central and lower rollers it is evident that the nuts g4 may be turned. By the above described adjustment of the rollers it will be seen that the closer the rollers are arranged, the more complete will be the binding action between the rollers and type, thus resulting in slightly increasing the spacerbetween the impressions through the additional pull upon said rollers and paper.-

For the purpose of printing circulars, postp ers or sheets where but one impression is de- IIO parted on the paper. It is also evident that I may construct my machine for the purpose of producing but one impression on the paper and in this case it is obvious that the upper roller might be omitted.

By releasing the set screw o', sliding the cutting block backward or forward, and locking it with the keeper k2, it will be seen that the distance between said cutting block and rollers may be increased or decreased as desired.

From the construction herein shown and described it will be seen that a simple, reliable and inexpensive device is provided for producing printed impressions on one or both sides of the paper strip and cutting the same into lengths. It will also be seen that the means herein shown of supporting the type in the printing position upon the central roller are such as to admit of the manipulation of said type by persons who are unskilled in the art of printing.
