OHROMATlC-PRINTING MACHINE.
. SIECIFIGATION forming part of Letters Patent No. 238,278, dated March 1, 1881.
Application filed July 12, 1880.
Toall whom it may concern y Be it knownthat I, THOMAS B. DOOLEY, a citizenof the United States, residing at Chelsea, in the county of Suffolk `and State of Massachusetts, have invented a new and useful Improvementin Chromatic-Printing Machines, which improvement is fully set forth in y the following specication, reference being had tothe accompanying, drawings.
My invention consists, chiefly, `rst, in a horizontally-movingbed-plate, which bears the printing form or; plates, in combination with a stationarybed `and vertically-operated platen, and with inking-rollers in stationary bearings, over which the printingsurface is carried, and also with a `horizontally-moving ink-plate, which receives the ink from the ink-r fountain or rollers connected therewith and delivers the same to i the rollers, which dis,- tribute the ink andconvey itK to the printing-` surface; and, secondlyn combining saidhorizontally-moving bed-platewith twostationary beds and two verticallyfoperated platens, so that an impression may be taken from `the printing-surface at each end of its travel, the ink-rollers being arranged between the'two platens and operating in connection with the ink-plate, as set forth.. y y y In thedrawings, (four sheets,) Figure 1 is a side elevation of appress embodying my invention, a part of the frame being broken away.
Fig. 2 is a front view of the press. Fig. 3 is a plan view of the same, one ofthe stationary beds being removed. Fig. is a horizontal section of vframe, taken on line l l in Fig. 1. In the plan views some of the lower parts are not shown.
'Ihe sides A A of the frame are ofsuch form and are held together by braces B B C G in a manner suitable for supporting the working mechanism. The two vertically operating platens D and E are held and guided in ways a, of bevel shape, at the sides of the frame, as shown. Projections or ends `F of shafts attached to the` platens D and E extend outward at the sides, on each one of which is piv- Y oted a bar or connecting-rod, G. Each one of the connecting-rods G is formed at the lower end to receive and form a bearing for a wrist- (No model.)
pin, b, of a crank fixed on an outer end of a shaft, H. It will be. seen that each of the platens D and E will have a vertical movement equal in distance to a part only of the throw of these cranks, and that at the time the impression is to be given these cranks and connecting-rods will be in position to exert great pressure, forming togglejoints. Impression-screws (not shown in the drawings) may be used for gaging the pressure in the manner that they are common-ly employed.
Located at the sides ofthe press are pulleys c, over each of which passes a cord, d, one end of which is attached to a connecting-rod, G, and the other end to a weight, as shown. Each crank in its rrevolution will leave the connecting-rod Operating therewith on one side of aline extending vertically from the center of thecrank, and thereupon theweight and cord d will swing the con-necting-rod over to the other Vside of said vertical line to a stop, c, and toa position where it will receive the crank-pin for the next reciprocating movement ofthe platen. Springs may be arranged to take the place of the weights and cords d.
Each of` thetwo beds I and J is fixed in a horizontal position to the frame of the press by suitable fastenin gs, as by the bolts f passing through ears or projections at the corners of the beds and on the frame, and through blocks g, which are space-blocks between the beds and the frame or body of the machine.
There is one horizontally-moving bed-plate, K, to which are fastened, on the under surface, the forms or platesthat is, the printing-surface. This bed-plate slides on ways or guides h, fixed to the frame. These ways or guides may be of such form and bevel as shown, to keep the bed-plate in true position, being also adjustable. The bed-plate K has a reciprocating horizontal motion, by means of racks t', attached thereto, which mesh into gears L on a shaft,j. This shaft has bearings in cross-pieces joining the stationary beds I and J, and has a pinion, M, xed thereon atone end. On each of the shafts H H is a gear, N. These two gears mesh into a gear, O, on a shaft, P. On one end of the shaft P is a cam, Q, which is of the proper form to give the required motions and rests. The cam Q gives a reciprocating movement to a'rod or bar, R, by means of studs or rollers fixed tothe rod or bar and bearing on the cam, as shown, the rod or bar being suitably guided. The rod or barR has a rack, which meshes into the pinion M. On the other end of the shaft j is a bevel-gear, k, which meshes into a bevel-gear on avertical shaft, l. On the lower end of the shaft l is a bevel-gear, which meshes into a bevel-gear, m, on a horizontal shaft, a. The shaft n has thereon two gears, S S.
I have shown two ink-fountains, T T, each located under a platen, though, in many cases, one only need be employed. Each fountain has partitions o, as many as are required to hold the inks of the several colors used. Each fountain has the usual ink-roll p, which may be a straight roll having the partitions o t closely thereto, so that itwill receive and hold the different-colored inks separately thereon. An ink-plate, U, moves horizontally on rollers q and r, in such relation to the ink-fountains as to receive ink therefrom by means of a swinging roller, s, connected with each fountain, and which carries ink from a fountain-roller to the ink-plate. This ink-plate U has recesses or grooves t running in the direction of the reciprocating movement of the plate, so that it will present separate surfaces to receive and hold separately inks of different colors, each surface bearing ink of the desired color. Racks V, fixed to the ink-plate U, mesh into the gears S, and by these the ink-plate may receive a movement back and forth to receive the ink from the fountains, and deliver the same to a roller, W, under which it passes. While the ink-plate has this reciprocating movement the ink may be further distributed thereon by dis- 4o tributing-rollers u, which, lying diagonally thereon, will have an alternate endwise movement. The rollers u should have grooves of sufficient width, so as not to carry ink from one surface to another on the ink-plate. There are also other racks, c, fixed to the ink-plate U, which, meshing into gears on the shaft of the ink-roller W, insure the proper revolution of that roller. There are two ink-rollers, w w, bearing on the ink-roller W, and two larger rollers, X X, bearing against the rollers w. These ink-rollers may be geared together as shown,toinsuretheirproperrevolution. Other rollers, bear against the rollers X, and rollers y against the rollers x. The rollers y are situated so as to deliver the ink onto the forms or vplates on the under side of the bed-plate X-that is,1 `onto the printing-surface.
The ink-fountains T rest on ways Y, on which they may be slid for the ready removal or ad- 60 justment of the same.
"Projections z, xed to the platens, enter suitable recesses in the bed-plate, to lock the same in position while the impression is bein ggiven.
The press may be operated by power ap- 6 5 plied tothe pulleyfon the shaft I). The arrangement of the mechanism and the relative motion and speed of the moving parts are such that .while the bed-plateis under one of the stationary beds a platen moves upward and an impression is given by means of the cranks and connecting-rods Working therewith, and the ink-plate is under the ink-fountain under the other platen. After that platen has moved downward, the bed-plate moves from under that stationary bed across the inkrollers y, receiving ink therefrom of the different colors, and onto the printing-surfaces, to and under the other stationary bed, for another impression given by the other platen, and so on. While the bed-plate moves from one platen and bed to the other, the ink-plate moves in the opposite direction under the inkrollers. These ink-rollers may be of the number and in position relative to each other, as shown, or there may be a greater or less number and differently arranged.
Paper may be drawn over each platen in a direction at right angles to the direction of motion of the bed-plate by mechanism (not shown in the drawings) similar to that employed in other bed and platen presses. Such mechanism should operate so that the paper will be presented intermittently and successively to the several divisions of the printingsurface, and thus receive the several different colors.
Besides superiority in other minor respects, my invention has the followin g-named very desirable features: There may be a great amount of ink-distribution, since the ink-rollers, revolving in stationary bearings and not being carried over the printing-surface, may be as large and as many as desired. Since in inking only the ink-plate has the reciprocating movement, a very light weight of parts need have this movement, while at the same time the grooves in the ink-plate prevent the mingling of the different-colored inks, and the grooved rollers may distribute in an efficient manner the ink of each of the several colors.
I claim as my invention- 1. The combination of a stationary bed, a reciprocatin g platen, inking-rollers to revolve in stationary bearings, a bed-plate reciprocating to have the printing surface or surfaces thereon rolled by one or more of said rollers, and to be imposition between bed and platen for giving an impression alternately, and an inkplate having a reciprocating movement to deliver ink to said inking-rollers, substantially as hereinbefore set forth.
2. The combination of two stationary beds, two reciprocating platens, inking-rollers located between said platens, a bed-plate bearing the printing surface or surfaces and to pass from one bed to the other, and in contact with one or more of said rollers, and a reciprocating ink-plate located to come in contact during its movement with one or more of said rollers, substantially as hereinbefore set forth.
