SPECIFICATION forming part of Letters Patent No. 608,813, dated August 9, 1898.
Application filed December 27, 1895. Serial No. 573,456. (No model.)
T0 all whom it may concern:
Be it known that I, FERDINAND WnsEL, a citizen of the United States, residing at New York, (Brooklyn,) in the county of Kings and` State of New York, have invented certain new and useful Improvements in Printers Proof- Presses, of which the following is a specification.
This invention relates te that class of printing-presses known as proof-presses, which are used in newspaper and other oices for taking proofs from forms of Vvarious widths, said press being arranged for feeding several independent webs of paper of a width corresponding to the forms set up; and the invention relates more especially to certain improvements in the printers proof-press for which Letters Patent were 4granted to me heretofore, No. 537,658, dated April 16, 1895, whereby the press is better adapted for newspaper-work, as it enables the simultaneous proof-taking of several forms of different widths and sizes and the feeding of independent webs of paper to the same, the ends of said webs bein g held by a suitable gripping device above the forms while the impressionroller is moved back over the forms and rcleased again when the impression-roller is moved forward over the forms for taking proof.
The invention consists of a proof-press for newspaper and other printing offices which comprises a feed mechanism by which the ends of the webs of paper are fed for a short distance after the proof-printed sheet is torn off, a gripping device for holding the ends of said webs in position without interfering with the form during the backward motion of the impression-roller, and of means by which the gripping mechanism is released when the impression-roller is moved in forward direction for taking proof.
The invention consists, further, of a printcrs proof-press in which the shaft of the paper-feeding rolls is provided with fixed and with adjustable and indepcndently-movable core pieces and an independent sleeve or sleeves also provided with fixed and adjustable core-pieces for supplying several webs of paper of varying width to the forms, as will be .fully described hereinafter and finally pointed out in the claims..
parts in Fig. 3.
In the accompanying drawings, Figure l represents a side elevation of my improved printers proof-press, in which the carriage is shown as-having reached the end of its 'forward movement, while the sliding cams are shown as shifted. Fig. 2 is a plan view of the same, partly in horizontal section, on line 2 2, Fig. l. Fig. 3 is a detail perspective View of the mechanism for holdin-g, gripping, and releasing the web or webs of paper for taking proef, drawn on a larger scale. Fig.
3 is a sectional view of the gripping mechanism corresponding to the position of the Figs. 4 and fl and 5 and 5 show, respectively, detail side views and vertical sections of the gripping mechanism in its successive positions; and Figs. 6, 7, and 8 are respectively a detail plan view, a vertical longitudinal section, and a vertical transverse section on line 8 S, Fig. 7, of the rollsupporting shaft Awith two different cores for the paper-rolls.
Similar letters of reference indicate corresponding parts.
Referring te the drawings, A represents the supporting-frame of my improved proof-press for newspaper and other printing offices. The supporting-frame is composed of upright standards@ o, which "are braced by longitudinal and transverse tie-reds. On the standards is supported a bed-plate B,which is provided at each side with guide-rails b b, on which a reciprocating carriage O is guided. Motion is imparted to the reciprocating carriage@ b v means of a transverse shaft D, having a crank-handle D', which shaft carries an impression-roller F, to each end of which are applied gear-wheels d, that mesh with fixed racks d', supported at both sides of the bed-plate B. By turning the crank D in one or the other direction the carriage C is moved forward or backward over the bedplate B. At one end of the carriage C, supported in inclined bearings c, are two inkingrollers E E, which are in contact with an inktransferring roller E', the shaft of which turns in bearings of the frame of the carriage. The roller F.v receives ink by means of intermediate rollersc c from a suitable ink-fountain E2, that is arranged above the intermediate rollers, as shown in Fig. 1. A. transverse shaft G is su orted in bearings at the u s PD D IOO
per ends of upright standards G at one end of the frame of the carriage C, said shaft carryin g a plurality of rolls of paper,whieh move with the carriage C over the bed-plate B. The webs of paper pass from the rolls over suitable rollers g g, of which roller g is a mere guide-roller, while roller g is a friction or pressure roller, said rollers bein g supported in the slotted arm of an oscillating frame g2, the pivot-shaft of which extends from one side of the frame of the carriage to the other. The supporting-frame g2 of the rollers g g is provided with forwardly-extendin g arms g3 on both sides, said arms carrying antifrictionrollers g4, which move over the guide-rails ZJ and over auxiliary rails r at both sides of the bed-plate and which serve for the purpose of oscillating the frame g2 when passing onto the rails r, so as to move the friction-roller g' into contact with the impression-cylinder F for the purpose of drawing the webs of paper in the opposite direction to the motion of the carriage when the carriage is arriving at the end of its forward motion. This feature is shown in my previous patent referred to, but its function and operation will be more fully described in detail hereinafter. At the opposite side of the impression-cylinder F the frame of the carriage is provided with a bending and cutting device I, which is composed of a cutting-blade t', that is sharpened at its lower edge and attached at its upper edge to a transverse bar Z', that is pivoted to the carriage C. A bending-bar Z2 is attached to the knife-blade t' and extended below the sharpcned edge of the same, the lower end of said bending-bar being rounded off, so as to press the paper into a groove 715 on the raised end portion of the bed-plate, as shown in Fig. 3, To the transverse bar 7l' is also attached an arm or finger i3, by which the motion of the cutting-blade and bending-bar in one direction is produced. To one end of the transverse bar z" is attached one end of a helical spring i, the other end of which is attached to a fixed point on the carriage, so that when it is not set to tension the spring will hold the cutting-blade and the bending-bar in inclined position adjacent to the impression-roller F, as shown in Fig. 5, When the carriage C arrives at the end of its forward motion, the linger abuts against the raised end portion of the bed-plate and moves thereby thecutting-blade andthe bending-bar against the tension of the spring Z into vertical position, as shown in Fig. 3, so that the bendingbar clamps the web or webs of paper firmly into the groove Z5 in the bed-plate, while the cutting-blade permits the tearing off by the attendant of the proof taken during the forward motion of the carriage. As soon as the carriage commences its return motion the contact of the finger with the end portion of the bed-plate is discontinued and the cuttingblade and bending-bar are returned again by the action of the spring 'Z4 into their former inclined position, as shown in Fig. 5,
The carriage C is provided at its opposite sides with sliding cams L, which are provided at their under side, below the shaft of the impression-cylinder, with inclined cleats Z, that are retained in position by suitable setscrews Z. On the upper side of the sliding lcams L are arranged inclined upwardly-extending lugs Z2. The cleats Z rest on eccentrics Z3, which are mounted on the verticallymovable standards C of the carriage, and can be raised or lowered by suitable handles, as is shown in my said patent, especially in Fig. (i thereof. The sliding cams L are guided on the eccentrics Z3 and on suitable lugs Z4 on the frame of the carriage and are operated in connection with stops ss on the bed-plate of the carriage, the stops s at left end of the bed-plate being arranged in lon gitudinal slots i s2 of the guide-rails b Z, whereby they can be adjusted and the motion of the carriage C limited as required by the length of the proofs to be taken. The shaft of the impression-cyll inder is journaled in bearings ofupright standards O, which are guided in vertical ways of the carriage C and engaged at their lower ends by the free ends of springs Z5, lwhich are applied at their opposite ends to the lower part of the carriage C, as shown in g Fig. l, the tension of said springs tending to .'fpress the standards C in upward direction ,and the eccentrics Z3 against the cleats Zof the sliding cams L. The tension ofthe springs 5 Z5 can be adjusted by tension-screws Z, turn l1 ing in lugs of the carriage C.
The carriage C is provided with antifriction-rollers C2, that rest on the sliding cams f L and facilitate the shifting of the same when i they arrive in contact with either stop s ors', the journals of said rollers passing through fslots in said standard, as in my patent referred to. These rollers C2 also retain the slidl ing cams in position against upward displace- L ment, so that said sliding cams may force `the 5 eccentrics Z3 and theimpression-cylinderF in downward direction against the motion of the 5 springs Z5 and into position for printing. The short auxiliary rails r, arranged at one end of 4the rails Z), are beveled at their inner ends and guided on stationary headed pins r2. The lsaid rails r carry upwardly-projecting pins 1 r3, which are each adapted to be engaged on l one side by a projection r4 on the carriage C and on the other side by the beveled nose rs on the end of the spring-finger r6. The beveled ends of the rails r permit the rollers g4 y. of the frame g2 to pass freely onto the rails 'r when the carriage C is near the end of its forward motion, whereby the frame g2 is oscilflated and the friction-roller g of the same brought in contact with the im pression-roller F, as shown in Fig. 3f. As soon as the im- 5 pression-roller leaves the form the printed proof would be drawn over the form or else torn unless the friction roller g is brought f against the impression-roller F. Thereby an 5 additional length of paper is fcd,corresponding to the distance between the end of the IOO IIO
- forni and the extreme limit of forward mothe clamp i2 and blade i.
tion, due to the fact that the friction-roller g is positively driven by reason of its pressing the paper web against the impression-roller.
During the backward motion the paper must be fed in the opposite direction until the end of the web is about to be released by Otherwise anobjectionable loop would be formed under the impression-cylinder. This feed of the web is secured by keeping the roller g' in contact with the impression-cylinder a short time after the return of the carriage is commenced, which operation is accomplishedl as follows: Vhen the carriage is nearing the end of its forward movement and the rollers g4 rise up on the ends of the auxiliary rails r, the pins r3 are engaged by the )rejections r4 on the' carriage, which causes t e rails to be pushed forward, with the said rollers still on the end of the rails, until the forward movement of the carriage is completed. By this construction the rollers g4 are permitted to leave the rails r very soon after the return movement is commenced. After the rollers g4 leave the rails r the inner sides of the noses ri engage pins rsand move the rails back to their former position. The inner sides of the noses r5 are beveled to such an extent as that they can they do not prevent their snapping over and past the pins as the carriage is being moved back. On the other hand, the outer sides of the noses are so much beveled as that during the forward movement of the carriage l they slip over and past the pins without acting on the rails. As the eXtra length of paper below the impression-roller would be in the way of the same during the return motion of the carriage, it is necessary to retain each web of paper by the gripping device, which device is formed by the cutting-blade c' and a bent gripping-finger m. (Shown in Fig. 3.) The gripping device holds the end of each web of paper in raised position above the form or forms, so as to permit the return of the carriage over the form without any tearing or rumpling up of the paper. ln order that the gripper may clamp the end of the web onto the blade fr', as hereinafter described,it is necessary that the end of the web be projected a short distance past the edge of the blade. This is accomplishedA by releasing the roller g slightly before the end of the web is released by the blade, whereby a slight loop is formed under the impressionroller, which loop straightens out, due to the sti ['tness of the paper, and the end of the web springs past the edge of the blade when released thereby. When the carriage arrives at the end of its backward motion, the gripping device is released and the paper fed during the forward motion of the carriage to the impression-roller and forms. As'soon as the impression-roller arrives over the form durA ing its forward motion the paper is held there by down upon the form and an impression` carriage over the forms.

Itaken. The paper being thus held between the impression-roller and the form, the same is fed automatically to the latter as the earriage moves along. When the carriage arrives at the end of its forward motion, as shown in Fig. l, the impression-roller F is lifted by the shiftingof the sliding cams L, caused by their contact with the end stops s', the shifting motion bringingthe cleats Zover the eceentrics Z3. Simultaneously the journal-bearin gs of the inking-rollers E E ride up on the inclined lugs of the sliding cams L, so that the rollers E E are thereby bodily lifted over the form. The impression-roller and the inking-rollers being thus lifted are then moved with the carriage in backward direcp tion over the form without coming in contact therewith until the carriage arrives at the opposite end of the bed-plate, when the opposite ends of the sliding cams L form contact vwith the stops s at that end, so as to shift the sliding cams L and move the cleats Z back over the eccentrics Z3, whereby the impression-roller as well as the inking-rollers are` returned into their former lower position and are then moved by the forward motion of the During the forsion-rollers and supply the ink required for v' printing the proofs, while the impressionlength of paper for taking the proofs.
I OCl As it is necessary in newspaper offices toV `take proofs from forms of various widths vvided with one or more fixed cores G2 and with one or more adjustable cores G, so as to provide for the exact width of each web to be used. The cores G2 G3 of one of the rolls of paper are attached directly to shaft G2, so that the same turns with the paper while it is fed to the impression-roller in taking proof. The cores G2 G3 of the other rolls are applied to independent sleeves G4, placed loosely on the shaft G', so that these rolls can turn independently of the shaft G and supply the webs to the impression-roller and forms when taking proofs of additional forms placed on the bed- The arrangement of an independent sleeve G4 on the shaft G is clearly shown in by whichmy improved proof-press is better heretofore patented by me.
It is obvious that a gripping device has to be arranged for each web separately.' The gripping devices are shown in plan viewin Fig. 2 and in their different successive posi- 'lhey are applied to a cranked transverse shaftt, which yis supported on the standards G of the earf riage Cback of the impression-roller F. To Ethe outer end of the cranked shaft `Z is keyed ITS `Figs. 7 and 8 and forms one of the features a short arm t' and adjacent and approximately at right angles thereto a cam t2, as shown in Fig. 3. A helical spring t3 is attached at one end to the shaft t and at the other end to the 5 standard G, said spring exerting a motion in downward direction on the cranked portion of the shaft t. Below the arm t and in contact therewith is arranged a slide-piece t1, which is guided in ways of a bracket 155, at- Io tached to the standard G. The lower end of the slide-piece t4 rests on the concaved wider portion t7 of an elbow-piece t6, the upper end of which is keyed to the outer end of the bar t. Adjacent to the elbow-piece is loosely applied to the bar t" a lever t8, which is located in the plane of the cam 152 and concaved at its upper end. The lower end of the lever t@ is slotted and connected with a fixed pin t9 on thc inner end of the sliding cam L, as shown in zo Fig.3. The parts described-namely, the arm t', the cam t2, the slide-piece t4, the elbow-piece t, and the lever t8-serve, in connection with the shaft t, bar i,'and the sliding cam L, to impart the required motion to the gripping 2 5 devices, so as to set them into the required positions for gripping` and releasing the ends of the webs at the proper time.
When the carriage arrives at the end of its forward motion, the sliding cams L are shifted 3oand the impression-roller and inking-rollers raised, as before described. Simultaneously therewith the arm i3 abuts against the end portion of the bed-plate and moves the cutting-blade and bending-bar down, so as to 3 5 press the web firmly on the bed-plate, as shown in Figs. 3 and G. The proof-printed portion of the web is then torn off along the cutting-blade by the operator. Vhen the impression-cylinderleaves the type,the frame 4o of the friction-roller g' is oscillated by the rollers g4 moving over the rails r, and the said roller g is placed in contact with the impression-roller. The contact of the arm 3 with the bed-plate imparts an axial turning motion to the bar z" and a lifting motion to the elbow-piece t6, which latter raises the slidepiece t4, the latter again lifting the arm t and turning the cranked shaft z5 against the tension of its spring t3, as shown in Fig. 3. The
wise raised, so that the proof-printed web can be torn off without being interfered with by the finger m. sliding cam L moves the upper end of the os- 5 5 cillating lever t8 away from the cam t2, as shown in Fig. 3. The operator then turns the crank D so as to move the carriage in backward direction over the form. On the return motion of the carriage the finger 3 is 6o released and the bar with the cutting-blade and bending-bar, returned by its spring fi into its normal position. The elbow t is moved in downward direction with the bar t", which motion is immediately followed by the slide-piece t, arm and shaft z5, which are under the influence of the spring t3, so as to place the parts into the position The shifting motion of the i shown in Fig. 4. Simultaneously therewith the lower end of the web is moved out, as be- `fore described, for a short distance beyond l the edge of the cutting-blade in the manner previously described. The grippingfinger m, being moved in downward direction by the F turning of the shaft t, takes up the end of the web and presses it against the edge of the cutz ting-blade, so as to firmly grip the same, asshown in Fig. 4, and holds it thus gripped `until the carriage arrives at the end of its backward motion. The sliding cams L, be-
i ing shifted by the stop s at the opposite end of the bed-plate, produce the lowering of the impression-roller and inking-rollers/as before described, and simultaneously therewith the [oscillation of the lever t8, and thereby bythe i action of its upper end on the cam t2 the turn- Eing of the shaftt against the tension of its spring t3, the lifting of the gripping-finger m,
and the releasing of the web, as shown in Figs. 5 and 5a. The operator then reverses l the motion of the crank D and moves the carriage forward over the form, so as to take the next proof, as before described. When the ping of the web by the latter and the descendl ing gripping-finger, as before described.
By placing several forms on the bed-plate yand arranging a corresponding number of rolls of paper on the shaft G several proofs can be taken at the same time, the widths of fthe rolls corresponding to thewidths of the 1 forms, while all the webs are simultaneously gripped during the return motion of the carriage, so as not to interfere in the least with 'the forms during the return motion of the g impression-roller over the same, and released at the beginning of the forward motion, so as not to interfere with the proper printing of the proofs by the press.
