' Specification of Letters Patent. Application filed March 81, 1905. Serial No. 263,186.

Patented A ril 2a, 1908.

. To all whom it may concern:

Be it known that I, WARREN L. GREEN, a citizen of the United States, and a resident of New York city, county and State of New York, have invented certain new and useful Improvements in Printing-Presses, of which the following is a specification.

My invention relates to plate. printing presses. In the old' method of printing from plates, in which the printing parts or design from which the printing is accomplished, is formed of engraved or intaglio lines on said plates, and in which the printing ink is first applied to the surface of. the plate, and then sai surface rubbed to remove all of fromthe lines, a great deal of time is consumed' and about nine tenths of the ink that is applied to the plate is rubbed off and wasted.

. The principal object of my invention 1s to provide a press that will avoid the necessity of rubbin off the ink from the surfaces, and that will tiereby save much time and trouble to the o erator; and also that will save the inkwhie has heretofore been wasted.

Another object ofmy invention is to provide means for-continuously printing from a surface provided with printing or intaglio lines.

- tails and features of the same, as hereinafter described and shown. 7 a

In the accompanying drawings, I have shown one embodiment of my improved press in which,

Figure 1 is a side elevation looking toward one side of the machine. Fig. 2 is a similar elevation looking toward the 0p osite side of the machine to that shown in Fig. 1. Fig. 3 is a longitudinal section throu h the line 33 of Fig. 5. Fig. 4 is a centra longitudinal vertical section through the line 44 of Fig. 5. Fig. 5 is a plan. Fig. 6 is. a front elevation. v the form cylinder and adjusting scraper, and means for operating the scraper. Figs. 9, 10 and 11 are details of the form cylinder and engraved or. printing plates, Fig. 9 showing a side elevation of the cylinder-and plates detached from each other, Fig. 10 showing an end elevation of the same, and Fig. 11"

showing a' transverse section through the cylinder plates and securing screws. Figs. 12 and 13 are details of one of the whiting cylinders. and burnishers, supports for the the ink except My invention consists in the press and de-- Figs. 7 and 8 are details showing same, and means for adjusting said supports, Fig. 12 being a partial vertical section, and Fig. 13 being a partial horizontal section.

imilar numbers represent like parts in all the figures.

1 is the main frame of the machine. 2 is the form cylinder, and 3 is its shaft which is journaled in bearings in frame 1.

4 is the upper part ofthe machine frame or superstructure secured to the frame 1 by screw bolts 5, so that said superstructure may be readily attached the frame 1. v

66 are blocks supported in vertical guideways 7. in the superstructure 4, and which blocks serve as vertically adjustable journal bearings for the shaft 8 of the impression cylinder 9.

1 010 are vertical pass through and en ed openings or holes and also in collars 11 structure.

1212 are Worm-wheels loosely surrounding the respective screws 10-10, and provided with integrally extending splines or feathers (not shown) engaging with a vertical groove 13 in the respective screws 10.

14 is a shaft journaled in bearings 15 of the superstructure and provided with worms 1 6- 16, saidshaft and worms being adapted to be rotated by a hand-wheel 17 secured to said shaft.' The lower ends of the screws 10 are secured to the block bearings 6 so that said screws may turn in said bearings. 'VVhen the shaft 14 is turned the worms 16'will rotate the worm-wheels 12, and by reason of their feathers engaging with the screws 10 will be rotated so as to cause vertical adjustment of the block bearings 6, and the impression cylinder 9.

' 18 is a gear secured to the shaft 3 of the form cylinder 2. This gear en a es with a gear 19 secured to the shaft 8 bit e imprese sion cylinder 9, and the rotation of the gear adjusting screws that gage with screw-threadat the top of said super- 18 will therefore cause the two

cylinders

2 and 9 to revolve so as to feed the paper between them and print the same. The

rotation of'tlie cylinders

2 and 9 is caused by the rotation of a large gear 20 which is secured to the shaft 3 of the cylinder 2, and the rotation of this 21, its shaft 22, the gear 23 on said shaft and an intermediate gear 24.

The form cylinder2 is formed of a core to which arc-shaped form plates 25 are secured,

in the superstructure '4,

gear 20 is caused by a driving pulley' to or removed from grooves 13, the

preferabl by means of screws 26, passing throu h oles in said plates into the core of the cy inder. These form plates 25 are preferably semi-cylindrical on their inner periphery corresponding with the adjacent periphery of the core o the cylinder, as shown in Figs. 4, 5, 7, 8, 9, 10, and 11.

27 is a fountain or pan for quicksilver or other amalgamatin material, supported on the frame 1 back 0' the

cylinders

2 and 9 in adjusting rock journals 28 in bearin s 29.

30 are set'screws passing through t e bearin s 29 and adapted to bear upon the journa s 28, so as to permit the fountain 27 to be rocked to its adjusted position, and fixed in such position. The fountain 27 is provided with a slit or outlet opening 31 at its portion nearest the two

cylinders

2 and 9, and the outer end of this opening 31 is filled with felt or other absorbent material 32, (see Fig. 4).

' This absorber should rest upon the cylinder 9 when the fountain is in its right position, as shown in Fig. 4.

3333 are two rollers for. applying the ink to the plates 25 of the form cylinder 2, said rollers when in use being in tangential contact with said plates.

34 is an ink fountain or tank situated at the rear end of the machine and in which the ink collecting roller 35 is situated and is adapted to revolve.

36 is a roller for transferring the ink to the siplplying rollers 33, and is adjacent thereto.

e ink is transferred from the collecting roller 35 to the transferring roller 36 through the medium of a rider or lazy friction roller 37.

38 is a horizontally adjustable frame having bearings for the journals of the

rollers

33, 36 and 37 The journal bearings 39 for the roller 37 are U-sha ed (see Fig. 3), and provide means by which said rollers can be lifted out or dro ed into place so as to rest upon the two

ro ers

35 and 36. The jour-' nals of the rollers 33 are rovided with gears 4040 which engage wit the gear 18 on the shaft 3 of roller 2, which gears 40 receive their rotary motion through said gear 18.

41 is a shaft adapted to revolve at slow speed, and on said s aft is secured a driving pulley 42 for transmitting motion to the shaft. The object of said shaft and pulley will be hereinafter described. Loosely journaled on the shaft 41 is a gear 43 which engages with a ear 44 secured to the shaft or ournal of rol er 35 and also with a gear 45 secured to the journal of roller 36, said gear 45 also engaging with one of therollers 40. The rotation, therefore, of the cylinder 2 and shaft 3 will, through the gear 18 on said shaft, transmit motion to the gears 40 and the

gears

45, 43 and 44, so as to rotate all of said

rollers

33, 36, 35 and 37, thus causing the ink to feed from the roller 35 to the roller 37 and from the said roller to the roller 36, then to the rollers 33, and from said rollers to the plates 25 on the cylinder 2. The rollers 33 should have a slight adjustment toward and away from the cylinder 2 for the purpose of supplying more ink, as desired, to the plates 26 on said roller 2, the nearer said rollers 33 are to the cylinder, the thinner the layer of ink that is applied to same. The adjusting mechanism is the following: 4646 are screws extending horizontally through screwthreaded openings in the sides of the frame 1, and' with their inner ends secured to the frame 38, so that said screws may turn in said frames. The turning of the screws 46 in onedirection will bring the frame and its supported parts, including the

rollers

33, 36 and 37, nearer to the cylinder 2, and the turnin of said screws in the reverse direction will bring the frame and said supported arts further away from the cylinder 2. The screws 46 are provided with lock nuts 47 for securing said screws and the frame 38 and its supported parts in their adjusted osition.

4848 are rollers for,collecting t e whiting, (preferably) to be applied to the form lates 25 on the cylinder 2. I have shown 1n the drawing two of such rollers, one bein journaled near the front of the, machine, an the other one near the bottom of the same. The shafts or journals 49 of said rollers are journaled in adjustable blocks or bearings 50, so as to permit the rollers to be adjusted nearer to or further away from the form cylinder 2. Said bearings are shown in the form of blocks (see Fig. 3) resting in guideways 51. 52 represents the holders for cakes or blocks 53 of the whiting. These holders are supported on rods 54 which are secured to the blocks 50, and said blocks are held in tens'ional contact with the rollers 48 by means of tension springs 55 situated between the holder 52 and a tension nut 56 on the end of the outer screw-threaded end of the rod 54. 5757 are rotary burnishers or polishers situated between the 'whiting rollers 48 and the form cylinder 2. These burnishers are provided with outwardly extending flexible lades or paddles 58 of hide, canvas, cloth or similar burnishing material, so that when said burnishers revolve, they will run over the peripheries of the rollers 48 and the form plates on the cylinder 2, transferring the whiting from said rollers to said form plates so as to polish the same.

59 59 are bearings for the journals of the burnishers 57 and which bearings are similar to the bearings 50 of the rollers 48. 60 is a right and left hand screw entering and engaging with corresponding screw-threaded openings in the

bearing

50 and 59, for the purpose of adjusting the rollers 48 and burnishers 57 in roper position toward and away from each ot er, and so that the paddles 58 will make the desired contact with said ,rollers 48. The screw 60 is provided with a collar 61, having openings 1n its periphery secured to the slowly positions toward and in which-a pin may be inserted to rotate the screw so as to cause the proper adjustment, as above stated. 62 are racks secured res ectively to the bearings or blocks 50, an extending outward from the same. 63 are pinions secured to their respective shafts 64, and engaging with the racks62, the purpose of said pmions and racks being to adjust the rollers and burnishers in their proper away from the form 0 linder 2, the rotation of the shafts 64 and the pinions 63causing the racks 62 to move and thereby cause saidadjustment. The shafts 64 are provided withhand-wheels 65 for rotating saidshafts. 66 is a "set screw which passes through the bearings of the shaft 64 and adapted to impinge upon said shaft so that the different parts may be set and held firmly after they have been adjusted. (The above construction is shown in detail in Figs. '12. and.13).

A slow rotary rollers 48 as follows: 67 is a beveled gear revolving shaft 41. 68 is a pinion engaging with the gear 67 and secured to a transmittlng shaft 69. On said shaft is a worm '70 which engages with a worm-wheel '71,'secured to the journal 49 of the upper roller 48. The slow revolution of the gear. 67 will, through the pinion 68-, worm 70 and worm-wheel 71, impart a slow revolution to said roller 48, which, in said revolution, will run against the block of whiting 53 that is held in contact with the peri hery of said roller. Secured to the sha t 69 is a beveled pinion 72 engaging with a similar pinion 73 secured to a shaft 74,

said shaft beingprovided with a worm 75,

engaging with a worm-wheel '76 secured to the shaft of the lower roller48. Said roller will be given its slow rotary motion in a manner similar to that of the upper roller 48, through the shaft 69, inions 72, 73, shaft 74, worm 75 and worm-w eel 76.

'77 is a shaft journaled in the frame 1 and provided with a pulley 78 which receives rapid revolution from a driving belt 79.

, Secured to the drives both the upper andthe lower bur-. means of a belt and pulley sys-,

guldewa s 86 in the shaft 77 is a. pulley 80,- which nishers 57 by tem 81, as shown in.Fig. 1, which system includes therein a tension roller. 84 for keeping the belt taut." This roller is jouma'led in blocks or bearings 85 supported in parallel frame 1 which extend toward t is belt and permit movement of the bearings 85 and roller 84, toward and away from said belt. w

.87 are adjusting screws passing through screw-threaded openings in the outer portion of the frame 1, and secured to the, bearing blocks 85, so asto permit said screws to turn in relation to. theblocks, whereby the inner and outer rotation of said screws will cause the blocks 85 and motion is imparted to. the- 9, said the under surface of the ment to permit it to rub a 95 and the cylinders 2 and the roller 84 to be Du adjusted, the inner rotation of the screws permitting the tension roller 84 to be pressed against the belt to cause the necessary ten-' sion ofsaid belt and the outer movement of said screws permitting said tension to be relieved or lessened.

88 is a rotary brush journaled in the two sides'of the frame 1 and extending parallel withthe cylinder 9: and having its upper periphery a little above the plane of contact of the two

cylinders

2 and 9. This brush 88 is provided with outwardly extending bristles 89 arran ed preferably as shown in Fi s. 5 and 6, a thou h this is unimportant. The shaft of this rush 88 is provided with a pulley 90 and said brush is rotated by means ofa belt 91 surrounding said pulley 90 and a pulley 92 secured to the shaft 8 of the cylinder 9. The brush 88 will therefore rotate in unison with, but more rapidlythan the cylinder 9. The object of said brush 88 is to sweep the lower surface of the strip of paper 93, as it comes from the roll (not shown), and before it passes between the cylinders 2 and sweeping or rotation of paper serving to straighten out and even up the same before it enters the two cylinders. 4

. 94 is a scraper preferably of metal, having a concave contact surface bearing against the periphery of the plates 's scraper has a slight longitudinal movethe plates 25 of the cylinder 2, so as to remove any excess of amalgamating material that may be on said plates after the ink has been deposited on the same by the rollers 33.

95 is a. longitudinal sliding frame to which 1 the scraper 94 is secured, and which has its longitudinal movement in guideways 96 in the frame 9 1 97 is a shaft which receives a slow rotary movement through the gear 67, engaging with a pinion 98 on said shaft 97.

99 is a rod or pitman pivoted to the frame an eccentric 100 on the shaft 97 The slow revolution of the gear 67 will cause the shaft 97 to rotate slowly, and by means of the. eccentric 100 and pitman 99, will slowly reciprocate the frame 85 and the scraper 94 back and forth longitudinally in contact with the form plates 25.-

. The operation'of the press is as follows: The fountain 34 being supplied with printing ink and the fountain 27 with an amalgamating material said fountain 27 should be adjusted so that the absorber 32 rests upon or touches the plates 25 of said c linder 2, and, the frame 38 should be drawn h gage the rollers 40 from the gear 18. The pr'intin lines of the plates-25 are then filled with in or grease. The machine is then put in operation through its driving shafts, and

9 begin to revolve slowly. ring the revolution of the cylinder 2 the the brush upon of the cylinder 2.

back and forth on i ack to disenperipheries of the &

eries therefore of the plates 25 with the exthe ink will only ception of the lines will be amalgamated or covered with an amal am which Will repel printingrink or to whic 'said ink cannot adhere. he

rollers

33, 36 and 27 are their adjusted inward so that the rollers 40 willengage with gear 18, and said rollers, as well as the roller 35 will be caused to revolve, and the ink will be fed to theplates 25, but the surfaces of said plates with the exception of the lines bein covered with the amalgam or an ink repe ling substance, be transmitted from the rollers 33 to and into said lines. The scraper 94 Will reciprocate longitudinally against the peripheries of the revolving plates 25, and thus remove any excess of amalgam and ink that might be on said plates. The whiting will then be transferred from the blocks 53 to the rollers 48, and from thence through the paddles 58. of the revolving burnishers 57 to the surfaces of the revolving polishing said plates. The

plates 25 thus Web 93, of paper or other material is fed over the revolving brush 88 between the

cylinders

2 and 9, and said Web is printed upon by the ink which was in the lines of the plates 25 being transferred to said web. As longas the machine is in operation, the

cylinders

2 and 9 will continuously feed said Web between them, and the printing upon the web from said cylinders will be continuous.

My invention provides a new and valuable printing press for engraved printing that will produce superior results, and that will save a vast amount of time and ink, that heretofore has been necessarily used.

My invention in its broader aspects is not limited to the precise apparatus herein described, as many changes other than those suggested may be made without departing from the main rinciples of my invention or sacrificing its 0 ief advantages.
