PRINTING-MACHINE.

SPECIFICATION forming part of Reissued Original No. 419,240,

To all whom it may concern:

Be it known that I, I IORACE G. BENDER, a citizen of the United States, residing'atAkron, in the county of Summit and State of Ohio, have invented certain new and useful Improvements in Printing-Illachines; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to whichitappertains tomake and use the same.

My invention relates to improvements in, printing-machines; and theinvcntion' consists in a machine especially adapted to sign-printing and the like, and which will print on rigid or flexible material, as boards, metallic plates, muslin, oil-cloth, and similar material, all as hereinafter fully described, and particularly pointed out in the claims.

In the accompanying drawings, Figure l is a sectional elevation of my improved machine. Fig. 2 is a plan view of the machine with the ink-rollers and part of the frame above the bed removed. Fig. 3 is a sectional elevation on line as 01:, Fig. 2, with all the parts broken away, except those connected with the revolving bed and the impression-cylinder, giving ahorizontal view between said cylinders and the revolvi-ng. bed. Fig. 4 is a section of the form carricr, belt, showing the longitudinal guides and the manner of securing the flexible form thereon. Fig. 5 shows a section of sprocket-chain-used on the carrier and both in plan and side view.

A represents the frame of the machine, the style or form of which is not material, provided that itaecommodates the machinery and serves the purposes I have in vie \Vithin the sides of the main-portion or body of the frame is hung on a shaft the revolving bed B, so arranged that'it'will come on about a level with the portion of the frame iudicated by the longitudinal bars A. table proper A is fixed on the frame A on suitable supports slightly below the level of the revolving bed to facilitate feeding therefrom between the said bed andthe impression-cylinder, and said table is cut away, so to speak, about its center to make room for the revolving bed. The elevation of the bed B above the feed-table need be but slight; but such elevation is desirable to-facilitate' Letters dated January 14, 1890.

the feed. Attention is called to Fig. 3,where the relative arrangement of these parts is shown.

Bet-ween the longitudinal bars main frame and the fixed feed-table A is arranged a moving feed-frame 0, supported on grooved sheaves or rollers b, which serve as guides for said frame. The frame 0 consists of two longitudinal bar. 0, connected at their front ends by a cross -bar 0', and provided with an adjustable fced-regu lating bar 0 neartheir front ends. This feed-bar c is held adjustably on the longitudinal bars 0 by setscrews and clamps c", or their equivalent arid 6 5 is designed to regulate and fix the point at which the printing shall begin with reference to the automatic fcedgear, as hereinafter fully described. It will be seen that the bars 0 are outside the ends and the carrying or supporting cylinderD' and do not come in contact with either of said parts. The said cylinder D is supported in adjustable bearings (l directly above the revolving bed, and said bearings are cushioned above to permit an upward movement in case of inequalities or the like in printing. The bearings (I may stand in vertical or inclined supports. The bed 13 and cylinder D revolve in unison, so as to give the requisite feed in printing.

In making duplicate or successive impresoriginal impressions or in such relation thereto as may be determined upon for shading or other elfects. I have overcome all difficulties in th s respect and am enabled to make same space or the finest adjustments from, as may be desired, and this by mechanism that eannot at the right time To effect these results I have provided each bar 0 of the feed-frame C with teeth. or gear c, arranged on the upper surface of said bars opposite each other, so as to act together. Then to mesh with these teeth or to effect the feed of said frame 0 at the right time I provide the carrier-belt E, which passes A of the 55 of the revolving bed 70 asge gear 0 and I00 zo farther.

25 Ordinarily the tion in the feed to .35 length and p in' View the gear on round the cylinder D and the idler-pulley F, i

Fig. 1, with a series of sprocket-links or other suitable gear G; These links or gear are on the edge of the carrier, so as to leave the in- 5 tervening space free for printing purposes as well as to make engagement with the gear on the feed-frame.

The 'dler;pulley F is hung in bearings f on arms f extending back from the main frame,

to and screws f are provided to adjust the said beari '5 back and forth on said arms, to obtain the desired tension of the beltand to adaptithe idler to belts of diiferent lengths. Motion is imparted to the belt and idler by the impression-cylinder, and when the sprocket-links are carried round to the front a Sllffieient distance they engage the teeth a on the feed-bars, which starts said bars and carries them along the full length of the gear, but no When this feed is exhausted, the feed of the opposed cylinders is supposed to begin, or is so far advanced on the-type that it will continue by reason of such contact, and

there is no longer need of feed by'the gear. type characters from which impressions are taken will be so placed on the carrier-belt that they will come into working position just before the sprocket-links pass out of engagement, thus permitting no mebe lost; but the two feeds may act in conjunction and the type or characters on the belt may extend between the sprocket-links thereon.

The belt or form carrier E is of a fixed of the width of the bed, so as to adapt it-to receive the largest size of type or other characters or two or more rows of the same on the form, if desired, and as it reeeives its motion from the cylinder D it must 4o necessarily move with it at the same rate of speed. The fact of this uniformity of speed enables me, by fixing the initial feed-gear thereon, to always bring my impressions exactlywhere I Want them. Take, for exam- Fig. 2 for illustration. There we have the carrier and a certain fixed relation of the type to said gear, which relation, so'far as this form is concerned, is unchangeable. New going to the feed-frame carrying the article to be printed uponsay .a sign-bcard-we find the end of the board at the front of the frame resting-against the adjustable regulating cross-bar c and the other end resting on the feed-table toward the cylinder D. This being the relation of the several parts and the machine beingstarted, the feed-gear will first pass into engagement and continue to its end. Just before reaching the end the type of the form will have come around and taken position between the bed B and the cylinder D, and the feed of these parts will continue to act till the end of the type-has been reached, which is toward the other extremity of the board. Meantime, the

6; feed of the board being taken from the feedgear by the cylinders, said gear and feed frame 0 have performed their allotted work,

and the frame 0 immediately upon being relieved is carried back to its starting-point by the counter-weight 0, attached to a crossbar 0 of said frame by a cord or chain. The

frameO,having returned exactly to its startthe same position as before and the type in the same relation to the gear a repeated impression on precisely the same spacemust follow. The counter-weight O has suflicient weight'to return the frame C to its normal osition as soon as the feed-gear is disengaged and while the printing is going on.

On or around the carrier or belt E, I fix a flexible form-base H, preferably of canvas,-

though other suitable material may be used for this purpose, and said base is stretched upon the carrier and its ends fastened thereto by lacing or otherwise to prevent creeping on the carrier. Then, to hold the form apron or base in perfect alignment on the carrier, I provide slightly-raised flexible guide-strips I, glued, cemented, or otherwise temporarily and removably attached to the surface of the carrier in parallel lines and of such width apart that the type-form will rest snugly between the same. If wider or narrower canvas be used for the form, one or both of the strips I will be moved inward or outward, as may be required, and in no case will they be deep enough to interfere with the print. Correspondingly-adjustable guideways I are fixed on the table of the mainframe.

The type or other characters employed are made of leather, and they are attached to the motion in the feed when the gear has gone to the extent of its movement,as above described. The length of the forms is determined before IIO they are put on" the carrier, and the carrier and forms have each a eertain fixed length, which remains unchanged for a given piece of work. If a longer impression is to be made than a given length of vform and carrier afford, a carrier and form of greaterlength will be used.

The foregoingdescription relates to the use of the machine for printing on boards or other rigid materials which are fed horizontallyon a bed, as herein described. The machine, however, is convertible to print-on fabrics, oil-cloth, and the like, in which latter case the bolts of goods are supported on a suitable roller, as L, Fig. 1, and carried over the revolving bed B to be printed and then wound upon a suitable reel, drum, or roller M.

The type or other characters employed are rial may be used for this purpose. Preferably they are made of a leather-like belting, which has a hard smooth surface and a good body; but any kind of leather affording a suitable printing-surface and adapted to this work may be used.

Among the' advantages of leather for this style and method of printing may be mentioned the following: Its flexibility, adapting it to the cylinders and a curved working surface; its yielding qualities, adapting it to such other differences that them to the work of a uneven surfaces as may occur in the material printed upon, and in spite of which it will produce full and clearly-defined impressions over the entire surface; its readiness to receive the ink or paint and to impart perfectlyuniformimpressions and to clean itself with each impression, leaving its supply of paint on the material and coming away clean; its being proof against chemical deterioration fromthe paints, sizings, and the like used in this work; its comparative inexpensiveness and the ease with which it is cut, punched, stamped, or engraved to meet the demands of the great variety and character of the printing to be done, no two orders of which are alike. These and other advantages appear in leather characters, and especially adapt machine designed to print and operate as herein described. The form is made by laying the flexible support or apron on a flat surface and then adhering the characters temporarily thereto in the proper relation, just as type are set for ordinary printing, been done the characters are removed and washed. In this work the paint by which the printing is done is such as will stand exposure to the weather, like paintin ordinary sign-painting, the hand-work in which this machine is designed to substitute, as well as to do such other printing,' as it may be capable of. The feed-gear might be arranged on one side alone; but would not work as satisfactorily as on both sides.

A group of ink or paint rol'ls N O is shown in Fig. 1 above the cylinder S; but these in themselves are old, and in thismachine serve the usual purpose of supplying and distributing ink or paint to the type-form. In any case, however, it is desirable to so distribute the same to the roller that it will be coated only the width of the characters on the form. The cylinder D has vertically-adjustable bearings to adapt it to printon materials of different thicknesses, as well as to provide for possible differences in depth of type or may occur. Suitable gears,'belts, and pulleys are provided to convey motion to 'the' several revolving parts from the shaft P.
