PRINTING-PRESS.

SPECIFICATION forming part of Letters Patent No. 435,774, dated September 2, 1890.

l Application filed Tilly 18, 1889. Serial No. 317,903. (No model.)

To all whom it may concern:

Be it known that I, BERNARD Il. SPECIQ BAUCH, of Newport, in the count-y of Campbell, State of Kentucky, have invented certain new and useful Improvements in Printing- Presses,of which the following is a specifica tion.

My invention has for its object to construct a platen printingpress which shall have greater capacity and capabilities than the presses of that character now in vogue; and it is embodied in a duplex machine carrying two forms, opposite to which work two platens, and provided with duplicate inking devices and driving` Inechanisms, the machine being adapted to print at the same time the same or different jobs from the ltwo forms, or to print upon opposite sides of the same sheet, the paper being taken from a roll or rolls and automatically fed and cut into sheets.

The features in which my invention cousists will be developed in the course of the following description, and will be more particularly pointed out in the claims.

The machine which is the embodiment of my invention is particularly adapted to jobwork, and while it is duplex in its construe tion it will be understood that many of its features are adapted for use in single machines.

In order that Iny invention may be understood, I have shown it in the accompanying drawings, which are illustrative in their nature, some of the parts being out of proportion.

Referring to lsuoli drawings, Figure l is a front side view of a duplex machine embodyingmy invention, parts being broken away. Fig. 2 isa top plan View, one-half of the machine beingin horizontal section on the line 2, Fig. l. Fig. 3 is a rear side view of one-half of the Inachine. Fig. 4. is a vertical section on the line44,Fig. 2. Fig. 5 is an end view. Fig. 6 is avertical section of a portion of one end of the m aehine, showing the platen turned over for adjustment. Fig. 7 is a detail view of the knife.

The main frame-work of the machine, which is stationarily supported and upon which are mounted thevarious operative parts,is formed to have a horizontally-extending and comparatively low portion at each end, upon which are supported the reciprocating slidin g frame which carries the platens and the paper feeding and cutting devices', and these portions I have indicated, generally, by the letter A.

Between the end portions of the frame is an elevated portion, (represented by A,) in and upon which are mounted and supported the chases carrying the forms, the inking devices, and most of the shafts and operating connections for imparting motion to the various parts of the apparatus, while below the portion A the frame-work (here represented by A2) supports certain of the connecting parts of the apparatus.

B is the main power-shaft, provided with fast and loose pulleys Z) b', and, if desirable, with a hand-wheel B', and journaled at its inner end in a bearing l, located centrally' in the upper central portion A of the frame, and at its outer end in a bearing 2, supported on a bracket C, projecting laterally from the main frame. The power to drive the various moving parts of the machine is taken from this single shaft, which is provided wit-hna gear-pinion D, with which mesh two large gear-wheels E E, arranged upon opposite sides of the pinion D and .mounted upon transverse shafts E', supported in the upper central portion of the frame-work.

Since the construction of the frame-work and the arrangement and disposition of the operative parts are duplicated upon the opposite sides of the central shaft B, it will be necessary in the main to describe but one end of the machine. The beds F, in which the chases are supported, are at the ends of the upper central portion A of the frame-work, which at these points has expanded side plates 3, the edges 4. of which form the tracks upon which run the inking-rollers for the form. The bed F is arranged between the lower straight and preferably vertical portions of the track 4, while between the upper curved portions thereof is placed an ink-distributing plate 5.

f lhe chase may be locked in the bed in any preferred manner, a spring-catch device f being shown.

The ink fountain or fountains 7, from which the ink is taken for the forms at the opposite ends of the machine, are located centrally upon IOC and preferably above the top bars of the upper central portion A of the frame and may be of any usual or preferred construction. From the fountain the ink is taken by a roller 8, mounted in a swinging frame, and delivered to a larger roller 9, which has areciproeating motion in a direction parallel with its axis imparted to it, in order better to. break up and spread the ink. The roller 8, which is reciprocated so as to be alternately broughtv into contact with the roller 10 of the fountain and the large ink-roller 9, is mounted so as to be free to turn with whichever roller it is brought into contact in the arms 11 of rocking frames mounted upon the opposite bars 6 of the frame-work. One of these rocking frames, preferably the one on the front side of the machine, is provided with an arm 14, carrying at its end an anti-friction roller 13, which rides upon a cam 12 on the shaft E', the end of the arm 14c bein g constantly drawn toward the cam by a spring 15. The cam 12 may be, and preferably is, formed on or secured to the rear face of the wheel E. The roller 9 has imparted to it a rotary motion, its shaft being belted to a pulley 16 on the shaft E', and is preferably also reciprocated in the direct-ion of its axis by a rock-shaft 17, which carries at its upper end an arm 1S, provided with a roller or block 19, seated in a groove in a wheel 2O at the end of the shaft of the roller 9. The shaft may receive its rocking motion in any preferred or convenient manner. I have shown it provided with a gearwheel 2l meshing with a rack 22 on the reciprocating frame carrying the platens. The ink is taken from the large roller 9 and delivered to the spreading-plate 5 by a roller 23, mounted so as to turn freely in the upper end of the arms 24 of a swinging frame I, supported loosely upon a rock-shaft G, mounted in the main frame-work. This shaft has the frames or plates H, secured to its ends, from which plates it receives its motion, they being connected with the reciprocating frame by links h, so as to be rocked thereby.

g is a tappet or wi per ad]- usta-bl y su pported upon the shaft G, opposite to whichis mounted a contact-piece 25 on a cross-plate 29 of t-he frame I. The frame I is under the constant influence of a yielding force which tends to rock it so as to bring the roller 23 into contact with the roller 9, and this force I obtain from a spring 26, mounted upon a sliding rod v27, and compressed between some stationary port-ion of the frame of the machine and an arm 28 of the frame I, although I might obtain it by other means which will readily suggest themselves to those skilled in the art. As the shaft G is rocked in the direction of the arrow, Fig. 4, the tappet g is brought into contact with the piece 25 and causes the frame I to rock therewith, carrying the inking-roller 23 over the spreading -plate 5, as shown in full lines, and causing the spring 26 to be compressed. lVhen the shaft is rocked in the opposite direction, the frame I follows the tappet,` under the influence of the compressed spring, until the roller 23 is brought against the roller 9, whereby it is stopped, while the tappet may continue its movement further and independent of the frame, as indicated in dotted lines, Fig. 4. It is desirable to be able to change the point in the oscillation of the shaft G at which the tappet shall make contact with the piece 25 and begin to move the frame I, in order that the extent to which the roller 23 shall be passed over the plate, and also the relative duration of its engagement with the roller 9 may be regulated. This adjustment may be secured by making the tappet g adjustable around its shaft and providing it with a set-screw 32, or by mounting the contact-piece 25 upon a slotted plate. 30, adj ustably secured to the cross-bar 29 of the frame I by the set-screws 31, both means being illustrated in the drawings. The ink is taken from the spreading-plate 5 to the form 33 by the rollers 34, which are mounted in the outer ends of the spring-rods 35, which are held in and take their motion fromthe frames or plates H. The ends of the rollers 34, or wheels mounted on the shafts thereof, run upon the tracks 4 on the side plates 3 of the form-bed, the rods or other supports for the rollers being mounted upon the outer sides of the plates 3. The supporting-arms 24 for the ink-roller 23 are mounted inside of the plates 3, so that they do not interfere in their movements with the rollers 34 or their supporting mechanism, and the plate 5 is slotted near its edges, as at 36 36, to permit the forward movement of the arms as they carry the roller over the plate.

Having thus described the inking devices, I Will now describe the platens and the mechanism whereby they are moved to carry the paper against the forms after they have been inked.

In a duplex machine of the character which I have shown the forms are supported at or near the opposite ends of the stationary framework, and the platens are moved toward and from them, preferably with an alternate motion-that is, one platen approaches its opposing form as the other platen recedes. Thesemotions may be secured in dil-ferent ways and by various mechanisms, that shown in the drawings being the one preferred. It consists, in general terms, of a rectangular frame supporting at its opposite ends the platens and having a rectilinear sliding motion on the stationary frame-work of the machine to carry the platens to and from the forms. This platen-carrying frame is composed of two plates K, having expanded end portions k by the narrow barportions 7c. The opposite expanded portions c of the framepieces K are connected by cross -bars 37, which form pivotal supports upon which theI platens are hung between the plates 7c.

38 38 are ways on the end portions A of the main frame-work upon which the platenframe slides, the bearing-surfaces which ride IOO ITO

weight thereby permitting the connectingbars k' to be made quite light. The platen- -frame is driven from the shafts E E', the

wheels E being provided with the wrist-pins e, which are connected by the pitmen L L with lugs upon the platen-frame. The shafts E are provided at their rear ends with crank or wrist wheels M, each connected by a pitman L with the platen-frame. I prefer to employ these four connections between the shafts E and the platen-frame, as thereby a more steady motion is imparted to the latter and a better distribution of power is effected; but it will be understood that a single driving connection between the platen-frame and some moving part of the apparatus would be operative.

40 40 are the standards for receiving the rolls of paper 4l, supported adjustably upon the upper sides of the end portions 7c of the platen-frame above the platens, and 42 are adjustable outwardly-extending arms supported from the sides of the standards 40, and carrying at their ends rollers or turning shafts 43, which are used when the paper is being printed on both sides. The platen consists of a block or plate of metalN, the cheek or side pieces n of which are perforated and hung upon the shaft 37, so as to turn thereon. To this plate or block is secured in any suitable manner, as by the bolts 39, the bed or plate O, which forms the platen proper, and which may be of any preferred construction. By hanging the platen upon the shaft 37, so as under proper circumstances to be free to turn thereon into the position shown in Fig. G, the Work of making ready the platenthat is, adjusting the yielding face thereof so as to secure a good impression-is rendered easy, since it is not necessary to work in the contracted space between the platen and the form, as would be the case were the platen fixed immovably in its frame. It is to be understood that in a machine constructed and proportioned as shown the roll of paper is to be removed and its standards slid or turned out of the way before the platen can be turned up.

In order that the platen may be always stopped in exactly the proper working posi tion when turned down, I provide it with a stop consisting of a lug or plate 44, projecting from the plate N and bearing against a fixed abutment, such as the cross bar or piece 45 between the plates of the platen-frame.

n n are perforated lugs carried, respectively, by the plate N of the platen and the platen-frame, and adapted, when the platen is turned into working position, to have their perforations register to receive a key, pin, bolt, or other locking device 47 for holding the platen in position. By arranging the beds for the forms at the ends of the main or central part of the machine and the platens outside thereof the latter are the more accessible for the purpose of making ready and the like than in those machines*wherein the platens reciprocate between the beds which face inward toward each other.

I will now describe the devices whereby the paper is fed through the machine, is cut, and is delivered in printed sheets. These paper feeding and piling devices are arranged substantially horizontally, so that the sheets as they are severed and delivered lie fiat and may be conveniently piled one upon another, as they are by the ly-delivery mechanism now in common use, but by a mechanism oecupying less space and operating with less friction and noise. Frein the roll 4l the paper passes downward in front of the platen, between it andthe form, from which it receives an impression at each reciprocation of the platen. After being printed upon the paper passes to a paper carrying or feeding device situated below the platen in the end portion A of the main frame-work.

The paper feeding and piling devices consist of two sliding frames connected to be moved in the same direction and at substantially the same time, and provided with gripping devices which grasp the paper, anda cutting and paper-clamping device is situated between the said sliding frames. The sliding frame to which the paper is first delivered after passing the turning shaft or roll 46 is represented generally by the letter P. It consists of two end pieces 49, sliding in ways 48 on the stationary frame and conneeted by a cross-plate 50, adjacent to which the paper passes and against which it is clamped by nippers 5l, secured to a transverse shaft 52, mounted in the end pieces 49. The frame P and the nippers 5l receive their motions from a cam or eccentric Q on the shaft E', which operates upon a roller on the end of a lever R, fulcrumed on a standard r. The lever R is connected by a rod S with an arm 53, secured to the shaft carryingthe nippers, so that when the rod is forced forward in the direction of the arrow, Fig. 4, it first causes the shaft 52 to be rocked, bringing the nippers against the under face of the crosspiece 50, and thereby clamping the paper. The engagement of the nippers with the piece 50 stops the rotation of the shaft 52, but the rod S, continuing to move, operates to carry forward the frame P, and with it the paper, which is tightly grasped. The frame P moves in the ways with sufficient friction to insure that the shaft shall be rocked and the paper positively grasped before it begins its forward motion, otherwise the feeding would be irregular, since the frame might be moved without the nippers operating at all. The paperfeeding frame P is brought back to the position shown in Fig. 4 by a spring T, coiled around the rod S between a collar S thereon and a stationary abutment t carried by the IOO IIO

' free end thereof away from. the eccentric Q for a greater or less extent of its revolution.

U is a second frame for delivering and piling the sheets of paper, constructed substantially like the frame P and also carrying a set of nippers, and sliding in the ways 48 in front of the frame P. frame U are mounted upon a shaft 56, and are brought to bear against the cross-plate 58 by the rocking of the shaft, which is provided with crank-arms 57, connected by the links V with the frame P. The nippers 55 operate, as do the nippers 5l, to catch the paper before their frame commences its forward movement, and since the forward frame U takes its motion from the rear one it fol` lows that the paper is fed forward a certain distance by the frame P before it is caught by nippers of the frame U. The reason for this arrangement and operation is to cause the paper to be fed forward by the rear set of nippers a short distance beyond a knife which severs the printed paper into sheets, so that its edge will project sufficiently far .beyond the same to be caught by the nippers of the delivering-frame. The links V are slotted at o, so that the connection between the two frames P and U is adjustable, permitting the outer frame to be moved toward or from the inner one into the position best suited for the work being done.

The nipper-shafts 52 and 56 are provided with suitable stops to limit the amount of motion which may be imparted thereto.

The knife or cutter, which severs the paper into sheets, is situated between the f rames P and U, and consists of a stationary blade or plate w, carried by across-bar 60 of their main frame-work, and a movable blade lV, supported by a vertically-reciprocated carrier X. The knife-blade carrier X is supported .upon guide pins or rods 6l on the main framework, and is forced toward the stationary blade w by the springs 62, which encircle the rods 6l. The carrier X is provided with brackets which carry rollers 63, beneath which are adapted to slide wedge-bars which lift the carrier X against the action of the springs 62 and separate the knife-blades.

The lifting-wedges 64 (best shown in Fig. 6) are carried by a frame supported so as to slide upon the ways 65 on the main framework beneath the platen. This sliding frame preferably consists of a lower plate 66, which carries at its front edge the wedge 64, an upper plate 67, provided at its opposite ends The nippers 55 of thisv with abutments 68, and a cross connectingbar 69 situated between the said plates.

69 are lugs or projections extending downward from the platen-frame between the abutments 68 on the sliding wedge-frames, with which they are adapted to engage at the eX- tremes of the. movement of the platen-frame to effect a sliding of the wedge-bars to operate the knife. The relative relation of the abutment-s on the wedge-frame and the projection on the platen-frame, and the timing of the various operative connections is such that the carrier X is elevated and the knifeblades separated during the time the paper is being fed forward, but is lowered immediately they begin their backward movement.

70 is a plate secured to the rear face of the carrier X by the screws 7l, upon which it slides, the plate being slotted to permit this movement. A spring 72, carried by the carrier X, bears upon the upper edge of this plate and causes its lower edge to project slight-ly beyond the edge of the knife-blade W. When the carrier is depressed, the edge of the plate 70 bears against the cross-bar 60 just back of the knife and serves to hold the edge of the paper after it has been out, and permit the inner feeder from drawing it back with it. It will be understood that when the knife-carrier is elevated by the wedges the clamping-plate is carried therewith, so as to leave a free space on the cross-bar 60 and knife-blade w for the paper.

As hereinbefore stated, a machine constructed as shown and described herein is adapted to print both sides of a web of paper,

IOO

and in Fig. l the course the paper takes when IIO of the frame, and passes back over the top of p the machine, following the course indicated by the dotted lilies, and being supported by the rods or bars 74, mounted in the upper ends of the removable standards 75. From the last-rod 74 the web ot' paper passes to the turning roller or rod 43, mounted in the arms 42, and thence passes to the printing, feeding, cutting, and delivering devices at the left-hand end of the machine, where the paper cut into sheets printed upon both sides is piled.

' A machine of the character described has almost unlimited capabilities as to speed, and yet works smooth and with less jar than is experienced in rapidly operating the ordinary single-platen pressesl now in vogue. The machine being once set in motion operates automatically, only requiring the services of an attendant to see that the parts are properly performing their respective functions. Each end of the machine having its independent driving and adjusting devices, it becomes possible to print at the same time upon the opposite forms jobs differing to any extent (within the capacity of the machine) in size, shape, or matter.

It will be understood that many of the parts maybe changed in their connection and arrangement without departing from my invention; therefore without limiting myself to the precise construction and arrangement of parts shown,
