FREDERICK HEUGHES,'OF ROCHESTER, NEW YORK.

IMPROVEMENT IN CHROMATIC-PRINTING PRESSES.

Specification forming part of Letters Patent No. H3 ,30, dated December 31, 1872.

To all'whom it may concern:

Be it known that I, FREDERICK LEE HEUGHES, of Rochester, in the county of Monroe and State of New York, have invented certain Improvements in Chromatic -Printing Presses, of which the following is a speciflcation The object of my invention is to provide a press for printing in several colors at the same time, and also one that can be worked at a high speed on one color; and it consists more especially in the combination of a series of type-beds and platens corresponding in number to the number of colors desired to be used, and arranged in a common vertical or nearly vertical line, the inking apparatus of each being entirely distinct, but operated by mechanism common to all.

In the drawing, Figure 1 is a side elevation of my invention, showing the platengate open. Fig. 2 is a vertical section in a plane parallel with the elevation, Fig. 1, with the platen-gate closed. Fig. 3 is a front elevation with the platen-gate removed.

A, Figs. 1, 2, and 3, is a supporting-frame, to which the various parts of my press are attached. B is the driving-shaft, provided with a fly-wheel, C, and having a pinion, a, Figs. 2 and 3, meshing into a gear, D, upon the shaft F, Figs. 1 and 2. The shaft F is parallel with B, and is provided with acam, E, which in its revolution actuates alternately the knee-1evers c and c. G G, Figs. 2 and 3, are typebeds, which move horizontally upon ways or guides 01 attached either to the beds or to the frame of the press, as desired. These beds are alternately forced toward the platens H H by means of the knee-levers cc, which are hinged to the type-beds andto strong cross-ribs o of the frame A, and are in turn actuated by the cam E. Springs e,'Fig. 2, operateto withdraw the type-beds and by this means also the friction-rollers f, which, at the central joint of the toggles, are kept in constant contact with the face of the cam E, whereby said toggles may be worked at a high speed without concussion. The platens H H are attached in a suitable manner to a frame or gate, I, Figs. 1 and 2, which is hinged at one side to lugs h, Fig. 3, on the main frame A, and is retained in operating position by the sliding bolts g, Fig. 1, which move in the lugs h and enter openings in the ears t upon the platen-frame, when it is swung into place. The bolts g are shown as operated simultaneously by the hand-lever j but any other suitable or con venient means may be adopted for forcing them into place. By this plan of hinging the platen-gate to the frame, both type and platens may be very quickly exposed to view, as indicated in Figs. land 3, and any adjustment or alteration readily made.

The inking apparatus is shown more clearly in Figs. 2 and 3, the roller-frame J moving upon ways K, which are parallel with the faces of the type-beds and platens. It is provided at or near each end with sets of inking-rollers m m, having bearings in adjustable boxes n. As the roller-frame reciprocates upon its ways, the sets m and m of inking-rollers come in contact alternately with the fountain-distributers 10 and p fromwhich they receive ink and convey it to the face of the types upon the beds G and G. The rollersp and p havebearings upon light frames L L, which also support the traveling-rollers 0, the carrier-rollers q, fountains 7", and fiat distribution 2, all of which may be constructed and operated in the manner usual in printing-presses. The frames L L are made to slide upon ways 8 upon the frame of the machine, on which they are clamped by binding-screws. By this means any inking-fountain with its distributing apparatus may be removed in a few minutes and replaced by another containing a different cclored ink. h

Motion is communicated to the roller-frame J by means of the shaft 2?, Figs. 1 and 2, having pinions b meshing into racks upon the side bars of the frame, as indicated, and this shaft is in turn actuated by a reciprocating rack, N, Fig. 1, which meshes into a pinion, 0, Figs. 1 and 3, on the extremity of said shaft. The rack N moves vertically upon a guide, a, upon the frame of the machine, and is thus operated by means of a crank, 0, upon the cam-shaft F, the pin a of which works in a horizontal slot in said rack. The pinions b andv and the stroke of the crank O are so proportioned that the requisite reciprocation of the roller-frame J is produced at each revolution of the shaft E, and it will be observed that such reciprocation is thus simultaneous and corresponsive with the movements of the type-beds G G. By reason of this construction of the parts and the proper relative arrangement of the crank O and cam E, the inking-frame J is at one extremity (and consequently at the slowest part) of its stroke, while the corresponding type-bed is being moved forward to make an impression. Furthermore, a considerable portion of the face of the cam E is made concentric with the shaft F, as indicated in Fig. 2, whereby one set of toggles and a typesbed are at rest during the forward movement of the other type-bed, such period of rest being sufli-- cient to allow the sets of inkingrollers m or m to pass over the form and return. Uponthe platen-gate I, I provide a'card-slide attachment, which consists mainly of a light frame, B, Fig. 1, having cross bars or rods 0 upon which the vertical guides D are adjustable by means of thumb-screws d, Fig. 2, for the purpose of admitting cards of various sizes. This frame fits over the edges of the platens loosely, and is retained thereon by clamp-screws 1), whereby the whole may be removed from the platen-gate in a few minutes. The guides D haveaslight groove upon their inner edges, terminating in a funnel at the top, to receive the cards in the usual manner. Rock-shafts e have bearings upon the side bars of the frame B, and the stops f are adjustable longitudinally thereon to correspond with the adjustment of the guides D.- These stops extend over the inner edges of the guides and are held against the platens H H by slight springs. The card drops down the grooves in the guides D against these stops and receives the impression, when, by a slight oscillation of the rock-shafts e, the

- stops are raised and the card passes down and eventually out of the machine. The oscillation of the rock-shafts is effected at the proper time by means of the toes g 9, Figs. 1, 2, and 4, the former acting upon its. rock-shaft in a downward direction only and the latter upward only, both being free one way, as indicated in Fig. 4. A projection, h, Fig. 2, upon the inking-frame J comes in contact with these toes alternately as said frame reciprocates, and allows the card to drop at the proper moment.

The operation of my machine is as follows: Suppose ink of a certain color to be supplied to one of the fountains 1' and a different color to the other, and the press to be set in motion. The inkingframe J passes down and the rollers m receive ink from the lower fountain while the rollers m pass over the upper form and ink it. Upon the return of the inkingframe the bed G advances and makes the impression, a card having been dropped into the slide by the operator at the proper moment, .which falls by its own weight and rests upon the stops f As the inking-frame begins to descend the projection it upon it trips the too 9, thus lifting the stops ff and allowing the card to drop by its own gravity to the next platen and rest upon the stops f, in which position it receives an impression from the types upon the bed G. At the next ascent of the inking-frame the toe g is tripped and the card thus allowed to drop into a receptacle provided for it below the machine.

Itwill be observed that by the proper relative arrangement of the types in the two forms, as now practiced in color-printing by two distinct operations, the samework is performed at a single operation, the two beds and platens and their inking devices being entirely. separate, but co-acting, as set forth. It will also be seen that by a multiplication of the typebeds and platensinthe same general line three, four, or six or more colors can be printed in the same manner at a single operation, the

parts being all actuated from a single driving shaft.

Furthermore, the press is well adapted to plain work in one color by simply throwing one of the toggles out of contact with the cam E, and by means of the peculiar construction of the cam and toggles a speed equal to that realized upon a cylinder-press may be maintained without difiiculty. A great ad vantage is also gained by the arrangement 9f the platens upon the swinging gate 1,. by which the types and the main working portionsgf the machine are rendered easy of access'alniost instantaneously. H p For feeding sheets into a press of this character it is proposed to use an endless v rgripercarrier running over suitable wheels, and arranged to introduce, transfer, and deliver the sheet at the proper time by means ofautomatic devices provided for that purpose; and this portion of the press has been made the subject of a separate application for a patent. 1 4.
