PRINTING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 419,240, dated January 14, 1890.

Application filed J une 8, 1889. Serial No. 313,602. (No model.)

To all whom, t may 0072/067172.:

Be it known that I, HORACE G. BENDER, a citizen of the United States, residing at Akron, in the county of Summit and State of Ohio, have invented certain new and useful Improvements in Printing-Machines; 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 which it appertains to make and use the same.

My invention relates to improvements in printing-machines and the invention consists in a machine especially adapted to sign-printing and the like, and which will print on rigid or fiexible 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 x fr, Fig. 2, with all the parts broken away except those connected with the revolving bed and the impression-cylinder, giving a horizontal view between said cylinders and the revolving bed. Fig. 4 is a section of the letter-carrier 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 it accommodates the machinery and serves the purposes I have in view. Within 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 frame indicated by the longitudinal bars A. The feed-table proper A2 is iiXed on the frame A on suitable supports slightly below the level of the revolving bed, to facilitate feeding' therefrom between the said bed and the impressioncylinder, 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 the feed. Attention is called to Fig. 3, where the relative arrangement of these part-s is shown. Between the longitudinal bars A of the main frame and the fixed feed-table A2 is arranged a moving feed-frame C, supported on grooved sheaves or rollers b, which serve as guides for said frame. The frame O consists of two longitudinal bars c, connected at their front ends by a cross-bar c and provided with an adjustable feed-regulating bar c2 near their front ends. This feed-bar c2 is held adjustably on the longitudinal bars c by set-screws and clamps c3, or their equivalent, and is designed to regulate and x the point at which the printing shall begin with reference to the automatic feed-gear, as hereinafter fully described. Itwill be seen that the bars c are outside the ends of the revolving bed and the carrying or supporting cylinder D, and do not come in contact with either of said parts. The said cylinder D is supported in adjustable bearings CZ, 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 cl may stand in vertical or inclined supports. The bed B and cylinder D revolve in unison, so as to give the requisite feed in printing.

In making duplicate or successive impressions of letters or characters on the same space much difficulty has been experienced in regulating the feed so as to bring the repeated impressions on indentically the same place as the original impressions or in such relation thereto as may be determined upon for shading or other edects. I have overcome all difficulties in this respect and am enabled to make as many repeated impressions in the same space or the finest adjustments either way therefrom, as may be desired, and this by mechanism that cannot fail to perform its function at the right time and in the manner desired. To eifect these results, I have provided each bar c of the feedframe C with teeth or gear c4, arranged on the upper surface of said bars opposite each other, so as to act together. Then to mesh with these teeth or gear c4 and to effect the feed of said frame O at the right time,I provvide the carrier-belt E, which passes round the cylinder D and the idler-pulley F, Fig. l, with a series of sprocket-links or other suit- IOO able gear G. These links or gear are on the edge of the carrier, so as to leave the intervening space free for printing purposes, as well as to make engagement with the gear on the feed-frame.

The idler-pulley F is hung in bearings j on arms f, extending back from the main frame, and screws f2 are provided to adjust the said bearings back and forth on said arms to obtain the desired tension of the belt and to adapt the idler to belts of different lengths. Motion is imparted to the belt and idler by theimpression-cylinder, and when the sproclet-links are carried round to the front a suffi-` cient distance they engage the teeth c4 on the feed-bars, which starts said bars and carries them along the full length of the gear, but no farther'. 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. Ordinarily the type or characters from which impressions are taken will be so placed on the carrier-belt that they will come into Working position just before the sprocketlinks pass out of engagement, thus permitting no motion in the feed to be 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 preferably made of leather and is of a fixed length and of the width of the bed, so as to adapt it to receive the largest size of type or other charl acters, or two or more rows of the same, if dey sired, and as it receives its motion from the cylinder D it must 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 exactly where I want them. Take, for' example, Fig. 2 for illustration. There We have in view the gear on the carrier and a certain fixed relation of the type to said gear, which relation,so far as this form is concerned, is unchangeable. Now, going to the feed -frame carrying the article to be printed upon-say a sigu-boardwe find the end of the board at the front of the frame resting against the adjustable regulating cross-bar c2, and the other end resting on the feed-.table toward the cylinder D. This being lthe relation of the several parts and the machine being started, the feed-gear will first pass into engagement and continue to its end. J ust before reaching the end the type on 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 form has been reached, which is toward the other extremity of the board. Meantime the feed of the board being taken from the feed-gear by the cylinders, said gear and feed frame C have performed their allotted work, and the frame C, immediately upon being relieved, is carried back to its starting-point by the counter-weight C', attached to a cross-bar c5 of said frame by a cord or chain. The frame C having returned exactly to its starting-point is then in readiness to move forward a second time, and the sign-board with its single impression will be placed thereon, exactly as it was originally, against the cross-bar c2, if a second impression is Wanted on the same characters. Obviously the feed of the frame C cannot begin until the feed-gear comes into action, and the board being in the same position as before and the type in the same relation to the gear, a repeated impression on precisely the same spacev must follow. AThe counter-weight C has sufficient weight to return the frame C to its normal position 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 H, preferably of canvas, though other suitable material may be used for this l purpose, and said form is stretched upon the carrier and its ends fastened thereto by lac ing or otherwise to prevent creeping of the form on the carrier if not so secured. Then to hold the canvas form in perfect alignment on the carrier I provide slightly-raised flexible guide-strips I, glued, cemented, or other- Wise temporarily and removably attached to the surface of the carrier in parallel lines, and of such width apart that the canvas typeform 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. Gorrespondingly adjustable guideways I are fixed on the table of the main frame.

The type or other characters employed are preferably made of leather, but other iiexible material may be used for this purpose, and they are attached to the form by glue, cement, or other temporary fastening, so as to be removable and. in such relation to the feed-gear as to lose no 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 they are put on the carrier, and the carrier and forms have each a certain fixed length, which remains unchanged. If a longer impression is to be made than a given length of form and carrier afford, a carrier and form of greater length will be used.

The machine here shown is' convertible to print'either on the more rigid materials to be fed horizontally on a bed, as above described, or on fabrics, oil-cloth, and the like, in which latter case the bolts of goods would be supported, say, on a suitable roller, as L, (shown in dotted lines, Fig. 1,) and carried over the revolving bed to be printed and then Wound upon a suitable reel, drum, or roller M in the IOO rol;

rear of the revolving bed. Then this class of printing is done, the feed-frame C and the feed-gear are not required.

The feed-gear might be arranged on one side alone, but would not work as satisfactorily as on both sides.

A group of inking-rolls N O is shown in Fig. l above the cylinder D; but these in themselves are old,and in this machine serve the usual purpose of supplying and distributing ink to the type-form. In any case, however, it is desirable to so distribute the ink to the roller that it will be inked only the width of the form printed.

The cylinder D has vertically-adjustable bearings to adapt it to print on materials of different thicknesses, as well as to provide for possible differences in depth of type or other differences that may occur.

Suitable gears, belts, and pulleys are provided to convey motion to the several revolving parts from the shaft I).

Having thus described myinvention, what I claim as new, and desire to secure by Letters Patent, is-
