PRINTING- SPECIFICATION forming part of Letters Patent No. 291,521, dated January 8, 1884.
Application filed October 30, 1882.
T all-whom it new concern:
Be it known that I,,WELLINGTON PARKER KIDDER, of Malden, in the county of Middlesex and State of Massachusetts, have invented certain Improvements in Printing-Machines,
of which the following is a specification, reference being had to the accompanying drawings, showing a printing -maohine which is the best form of apparatus now known to me for putting my invention into practice, and which also embodies certain features of my invention.
The essential operations in printing are properly classified as, first, inking the form; second, presenting the sheet or web to receive the impression fromthe inked form; third, taking the impression; and, fourth, delivering the printed sheet. f
The paper H is fed from a roll, (not shown in the drawings,) and is slackedoff from this roll, as described in my Patent No. 224,440, dated February 10, 1880. It passes between clamps h h, attached to the frame of the machine, the moving member h of which is actuated by the cam if, and thence over shaft 71?, partially around impression-cylinder D,thence partially around impression-cylinder D, and theneeover shafts h and h, and between the feed-rolls hi and h The shaft h is mounted upon the carriage F. On the impression or forward stroke of cylinder D the paper is first nipped between cylinder D and the form at the line marked 1 in the diagrams, Figuresl and 2, and that part of the paper between 1 and 2 receives the impression from form B, so that at the end of the impression the paper near the line marked 2 is nipped between the form B and cylinder D. N ow, all that part of the paper from 1 to 2 would remain flatnpon and sticking to form B at the end of the impression were it not for the shaft 72, and the clamps h h,- but as the paper is held by the clamps it renders over shaft h as that shaft rises, and is therefore stripped off the form :with the least possible resistance from the stick of the ink, and at the end of the impressionstroke the paper between the line held by clamps h h and the line 2 is as shown in Fig. 2. The paper from 2 to 3 receives the impres- 5o sion from form B, and is stripped off from (No model.)
form 13' by the motion of cylinder D over form B.
Fig. 1 is'a diagram showing clearly the position of the paper at the beginning of the stroke to make the impression when two forms are used thatis, when my press is a perfect ing-press; and Fig. 2is a like diagram, but showing the position of the paper after the impression has been taken. It will be clear from these diagrams that the function of shaft ha is to prevent the paper from bagging between it and the line where the paper is nipped between cylinder D and form B, and that this function is performed for cylinder D by the cylinder D. Cylinder D also performs an important duty in aid of cylinder D-that is, it keeps the paper between 1 and 2 away from the form until the moment before it is nipped between the form and the impression-cylinder. This duty is performed for cylinder D by the shaft h.
To prevent undue strain upon the paper lying between the line marked 2, where it is nipped bythe cylinder D and form B, and the line where itis nipped by the feed-rol1s h h, the 5 swinging shaft h is swung inward gradually, thereby slacking the paper as required to relieve it from strain; or shaft k may be mounted in the frame of the machine, and a shaft, h be mounted on carriage F, as shown in Fig. 5, the shaft h" then performing the same office for the paper between 2 and 3 that cylinder D performs for the paper betweenl and 2.
In the diagrams, Figs. 3 and 4 I have illus trated this the main feature of my invention, 8 5 where only one form is used, instead of two forms, as in my perfectingpress. In these diagrams the shaft h is a roll, which is pressed against the cylinder D during the impression, and consequently performs the functions 0 which in the other diagrams are performed by the clamps h h and the shaft h for, as the surface speed of h is just equal to that of the cylinder D, the paper is clamped, and also guided substantially as before. The shaft h 5 performs the same function in these diagrams, Figs. 3 and 4, for cylinder D as cylinder D does in the other diagrams for cylinder D, for cylinder D may be regarded as omitted from these diagrams, or, what is the same thing, I00
the form B may be regarded as omitted, and I roller g by an intermediate gear. The distherefore cylinder D ceases to be an impression-cylinder, and itsonly function is to keep the paper between 1 and 2 away from form B until the moment cylinder D is ready to force it against form B.
I have thus fully described the mode of presenting the web, as it aids much in understanding my new machinery for printing, which is shown in the drawings, and which I will now describe. Figs. 1, 2, 3, and 4 are the diagrams herein-- before referred to. Fig. 5 is a side elevation, showing the impression-cylinders in position to begin the impression-stroke. Fig. 6 shows the opposite side and theimpression-cylinders after the impression-stroke. Fig. 7 is a rear elevation, partly in section. Fig. 8 is a plan View, partly in section, showing the arrangement of the cylinders and driving-gear. Fig. 9 is a detail illustrating the form-inking mechanism and the mechanism for operating the fountain.
The frame of the machine shown in the drawings consists of two upright pieces, A A, a base, A", and the two beds, A A, the beds connecting together the uprightsA A, and the whole constituting a strong and simple frame. The beds A A support the type-forms B B. The impression-cylinders D D are mounted in carriage F, which is fitted in ways in the uprights AA. This carriageFis reciprocated by means of connecting-rods f and wrist-pins f, which are fast to the main wheels f f 2 are fast to the main shaft f and one of them I stroke of the carriage.
is geared to pinion f on the driving shaftf At each revolution of the main shaft f the carriage F moves up to the position shown in Fig. 6, and back to place, as shown in Fig. 5, the journals (Z of the impression-cylinders D D are mounted in eccentric boxes (1, and these boxes d are themselves. mounted in boxes in the carriage F. Each eccentric box d is fast to an arm, d", and these arms are connected by rod d, this mechanism causing the eccentric boxes d to throw the cylinders D D apart at one end of their stroke and to bring them together at the other end by means of cams d (1 as will be plain from the drawings. Each of the cylinders D I) is caused to revolve during its impression-strokeat a speed which will cause it to roll over the form without slip by means of gear wheel d and rack d, and the teeth of this gear and its rack are of such a length that they will remain in mesh when the cylinder is away from the form during its return-stroke.
The form-inking rollers G and the ink-distributing rollers g g g are also carried by the carriage F, the form-inking rollers G rolling upon the form on both the forward and back The rollers g g are metal inking-rollers, and are driven by a train of gears connecting with racks g. (See Fig.
9.) Each gear 9 meshes with a rack, g and also with a gear fast on the end of the roller 9. g This gear on roller 9 connects with a gear on These wheels.
tributing-roller g revolves with rollers g and g, and also has an endwise reciprocating movement, all as in the well-known rackand-screw distribution. The ductrolls g are mounted inlevers g, which are fulerumed on carriage F. Each duct-roll is held against its metal ink-distributing roll g by asuitable spring, except when the carriage F is near the end of its return-stroke, and during this time the friction-roll on the lever g enters cam 9 and the duct-roll is thereby forced into contact with the roll of the fountain 9 These fountains g are of the usual construction, except that their rolls are revolved by the pawland-ratchet mechanism 9 actuated by the levers 9 9 and the cam g. The ratchet is fast to one end of the fountain-roll g and the pawl is fulerumed on the lever 9 The feed-rolls h h and shears J are constructed and operated as described in my patent before referred to, No. 224,440, of February 10, 1880, and need no further description here. The swinging shaft k is operated by connecting-rod h, which at its lower end is attached to lever h", actuated by a cam.
The'operation is as follows: Assuming the paper to have just been fed the proper distance, which in the machine shown is the length of the form B, (or of the form B, for each is of the same length,) plus the margin, the clamp h h is closed, (or the paper is held in any other suitable way,) and consequently a portion of the web will be held at two points namely, the clamps h h or their equivalent, and the feed-rolls, the printing apparatus being all between these two points-and the slack having been taken out of the paper between these two points, for the feed-rolls 7L7 h 'have just pulled the paper through the machine and over a number of guiding-shafts, as well as over portions of the impression-cylinders, the impression-cylinders now commence their impression-stroke, and the paper is nipped at 1 between form B and cylinder D, and at 2 between form B and cylinder D. As the cylinders continuetheir impression-stroke the paper is pulled off form B in rear of cylinder D by shaft or roll h and off form B in rear of cylinder D by cylinder D, and is prevented from touching form B too soon by cylinder D, and from touching form B too soon by shaft h, (or h, when that is used; but for certain classes of work I prefer to use the swinging shaft 711 rather than to use h, as when using heavy ink, which is liable to be blurred by passing over shaft h At the end of the impression-stroke the cylinders are brought closer together, so that they will not bear on the forms on their back-stroke, and at or just before the end of the impression-stroke the clamp is opened and the paper is pulled forward by the feed-rolls, the feed taking place during the back-stroke of the impression-cylinders. Near the end of the back-stroke the duct-rolls g are brought into contact by means of the levers and cams g with the rolls of the earner s fountains g and take up asupply. of ink, and as the carriage F moves again on the impression-stroke the levers of these duct-rolls are drawn out of their cams, and the ductrolls come into contact with the metal inkdistributing rolls 9 and supply them with ink, which is distributed in a well-known manner. As the form-inking rolls G are mounted upon the carriage F, they are carried over the forins during the impressionstroke of the carriage F, and carried back again over the form during the return-stroke of the carriage.
When the paper passes directly from cylinder D to cylinder D, as shown in the drawings, and two forms are used, the register depends upon the length of feed and the position of the typesin each chase. Consequently the paper, after leaving cylinder D, should be carried under a shaft, hf, which is adjustable, in order to obtain a correct register of any desired length of sheet, to avoid the need of any exact relative adjustment of the types in each witha different-colored ink from that used on forms B and B. It is so timed that its impressions are taken during the impressionstroke of the carriage E, as the same feed, h h serves for all three of the presses. This third press is designed, mainly, for printing advertisements in newspapers or the like in ink of a color so different from that used for the surrounding matter as to make them prominent.
Inasmueh as the impression from form B on that part of the paper between 1 and 2 is outermost at the next succeeding impressionstroke of cylinder D, it is desirable, in order to prevent smearing, to change the tympanpaper used with cylinder D, and for this purpose a reel, L, is mounted in cylinder D, the paper from which passes througha slit in the cover of cylinder D and past suitable guides, h and Z, to a reel, Z on frame A. From time to time the reel Z is turned, in order to unwind the tympan-paper Zfrom reel L, and thus present a dry surface to bear upon the freshlyprinted side of paper H, and when the greater part of the tympanpaper Z is unwound from reel L it is rewound upon that reel from time to time. This can be readily done by the operator by means of suitable handles, (not shown or mechanism for moving either of the reels L or l at regular intervals may be readily devised and applied to the press.
The main wheels f? have counter-weights f 6 applied to them to balance the weight of the carriage F and the other parts, so that the machine may run smoothly at the rate of, say, sixty revolutions per minute.- At each revolution of the press shown in the drawings a newspaper printed on both sides, with one or more advertisements in red or some other striking color, is deposited on the table of the machine at M.
The forms 13 B are put in and taken out at that side of the machine which is shown in Fig. 5, the racks being at the other side. One ofthe bearers on each bed is preferably rigidly attached to or in one piece with the chase of that bed, as it must be taken out to receive the chase.
It is often desirable to run the machine without taking the impression, and for this reason cams cl are mounted, as shown, so that by a motion of lever d the cylinders are not separated at the end of their returnstroke.
I am aware of Patent No. 83,471, of 1868, granted to Royal Cummings, and disclaim all that is therein shown, my mode of presenting the web differing radically from his, in that in his mode the feed is simultaneous with the printing, while in my mode the feed takes place while the impression is thrown off.
What I claim as my invention is 1. In combination with a stationary bed and an impression-cylinder traveling over it, guides for the web, one at each side of the impression cylinder, and a feeding device which feeds the proper length of web while the impression is thrown off, all substantially as described.
2. In combination, two stationary beds, two traveling impression-cylinders, and a fgeding mechanism, substantially as describedfcombined together and-with suitable'guides, substantially as described, and operating to print both sides of a web, as set forth. 7
3. In combination, two stationary beds, two traversing impression-cylinders, and a third printing mechanism, substantially as described, with an intermittent web feeding mechanism, substantially as described, common to all three printing mechanisms, the first stationary form and its cylinder printing one side of a given length of web, the second printing the other side of that length of web, and the third printing mechanism printing on the same length of web already printed by the other two, all as set forth.
4. In combination, two beds, two impression-cylinders, a reciprocating carriage, and two sets of inking apparatus, both cylinders and both sets of inking apparatus being carthe other at the end of the impression-stroke anism, substantially as described, and the inof the carriage, and to throw each cyiinder terinittentiy-operating web-feeding mechan- IO away from the other at the end of the backism, substantially as described, all operating stroke of the carriage. together substantially as described.
