PRINTING-PRESS.

SPECIFICATION forming part of Letters Patent No. 613,271, dated November 1, 1898.

Application filed August 12, 1895. Serial No. 558,971. (No model.)

To all whom it may concern:

Be it known that I, CHARLES HENRY HEY- WOOD, a citizen of the United States of America, residing in Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented newand useful Improvements in Printing-Presses, of which the following is a specification, reference being had to the accompanying drawings and letters and numerals of reference marked thereon.

This machine is designed to print, stamp, or emboss and apply government postage or other stamps to envelops and cards. The paper, card, or material may be fed in a continuous strip from a roll or be cut into sheets or blanks and fed as described in patent issued to me February 4, 1890, or in any convenient or well-known way.

In the accompanying drawings, in which like letters and numerals of reference indicate like parts, Figure 1 is a front elevation of my improved construction, partly in section, with certain parts broken away to disclose the mechanism. Fig. 2 is a vertical section of the machine, taken on line 00 a: of Fig. 1, looking from the right-hand side of the machine. Fig. 3 is a View of one of the form-roller-carriage gears and journal made in one piece, on which is also fastened the gear 31. Fig. 4 is a side elevation of Fig. 3. Fig. 5 is also a View of one of the form-roller-carriage gears similar to the one shown in Fig. 3. Fig. 6 is a side elevation of the gear shown in Fig. 5. Fig. 7 is a View partly in section of the ink-cylinders, distributing-rolls, form-rolls, and some adjacent parts, taken as seen from the righthand side of the machine in Fig. 1, and represents the parts in the position reached at the time the impression is being made. Fig. Sis a horizontal section taken through the printing-bed and frames in Fig. 1 from left to right. Fig. 9 is an elevation of the inkcylinders and distributing-rolls, and Fig. 10 is a diagram showing the centers of the different gears.

A general description of the construction of the machine is as follows.

In Fig. 1, A A represent the sides of the machine, (shown also in Fig. 2,) B the girth or truss extending from one frame to the other, holding them rigidlyin position, and 0 an arch extending over and connecting :the top portions of the frames A A and providing a place on which isfastened the tympan D or platen by which the impression is made. E is a spurgear on the crank-shaft G.

In Fig. 2, H is the driving-shaft, on which is fastened gear F. (Shown only in this view.) The power is applied to this shaft, but it has been omitted in the drawings, as the power may be applied in any well-known. manner, either by a friction-clutch or a tight or loose pulley. Crank-shaft G is made with two ofiset crank-motions 7, from which the printing-bed receives its motion. On the right-hand end of the crank-shaft is the bevel-gear I, transmitting motion through its mate J to vertical shaft L. Vertical shaft L is supported in bearings K and M, fastened to the side of frame A. In this shaft L is securely fastened a feather 9, and sliding upon shaft L and feather 9 is the bevel-gear W. The feather 9 provides that gear W shall turn with the shaft L, while it is forced by hearing X to reciprocate upon the shaft, as will hereinafter be explained. In the frames A A are formed two channels or grooves. In these grooves or channels are shown the vertical slides Q and R. Connecting these slides at their lower ends is the truss or I-beam S. This is rigidly fastened to the slides in question, having ears cast upon its under side, as shown in Fig. 1, through which are pins 5 5, on which are pivoted the connecting eye-rods 2 2, extending into the stirrups 1 1 and retained therein by nuts 3 and 4. At the upper end of these sides, extending from slide Q to slide R, is the printing-bed frame t. This bed is formed of one piece, the central portion of which is made to receive the type-chase. The ends are formed in journals on which rotate the form-roller-carriage frames. The journals of bed T are keyed into the frames Q and R by keys 47 and 48.

Meshing with the bevel-gear W on shaft L is a bevel-gear V, fastened to the end of the horizontal shaft U. Just below gear V and fastened on the slide R is a box X, which surrounds the gear W, and as the slides R and Q, with box X, rise and fall through the action of the crank-shaft G the gear W is reciprocated upon the shaft L, while it is' revolved by the feather 9. The motion thus received is transmitted through the bevelgear V to the shaft U, 011 which are the two gears Y and Z. These gears mesh directly with the carriage-frame gears 17 and 18 on the printing-bed journals T T.

Fig. 2 shows a shaft N, on which is lever 0, connecting through link P to the center of the I-beam S. On the other end of the lever is fastened a spring, the object of which is to counterbalance the moving portion of this machine.

A designates a plate connecting the tops of the side frames A A and bracing them against lateral strains.

For convenience in more readily understanding the machine I divide the remainder of the description into three mechanisms, as follows: printing-bed proper, form -rollers and cylinders, and ink-supply.

Printing-bed proper.1n Fig. 1, 40 is the chase fastened to the surface of the bed T. (Shown best, perhaps, in Fig. 2.) 50 is the type or electrotype held in the chase.

26 26, Fig. 1, are tracks formed around the printing-bed T in such manner as to guide the form-rollers as they move around the bed, the trucks upon the form-roller arbors rolling upon this surface, as shown in Fig.2. These tracks are of such shape that the form-rollers as they rotate around the bed are carried into and out of contact with the ink-cylinders at the proper time. Extending through this bed from end to end is the tie-rod 44. On this rod between the tracks 26 26 of the bed (best shown in Fig. 8) is sleeve 43. This sleeve extends and fits tightly between the two tracks 26 26. Tie-r0d 44 extends through the parts, as shown, all being bound tightly together by nuts 45 and 46.

In Fig. 2 will be seen the shaft 33 on the left side of the printing-bed camway or track 26, and in Fig. 8 is shown a section through this shaft that it may more clearly be understood. At each end of this shaft are piniongears 32 and 34, the object being to transmit the motion from the outside of the printingbed to the inside. This is done by the gear 31, fastened upon gear 17. (See Figs. 3 and 8.) The motion is then transmitted to gear 35, fastened on the ink-cylinder frame 36 inside of the printing-bed.

Fowl-rollers and cyZmders.Figs. 3, 4, 5, and 6 are different views of the form-rollercarriage frames. In Fig. 3, 17 is a large gear twice the diameter of gears Z or Y on shaft U. The reason for this gear being twice the diameter will be apparent later. The gear is made with a large hub and with ears 19 and 19 projecting from the side. Through these ears are bored holes which serve to receive the eye-rods 20, as shown in Figs. and 6. Two of these eye-rods are used in each gear, only one being shown in Figs. 5 and 6. At the upper end of eye-rods 20 is the rocking claws 22, which in Fig. 1 are shown carrying the form- roll arbors 23 and 3!). On this eyerod 20 is a spring 21, and through the rod is placed a pin 27, thus causing the spring to retract the claws 22 toward the center of the gear-journals. In Fig. 2 it will be seen that there are two sets of form-rollers, one set 41 41 on arbors 23 and 38 being shown over the type, the other set 41 41 on arbors 38 and 40 being shown in cont-act with the ink-cylinder 30. It will be seen that as gear 17 is twice the diameterof gear Z and as gear Z makes one revolution to every impression of the machine gear 17 could not rotate but half-way around at every impression. Thus if the form-rollers are in the position shown in Fig 2, where the crank 7 on shaft G is in its downward position, then when the crank 7 is turned half-way around and the printing-bed has been raised up and is making an impression the form-rollers would then be in the position shown in Fig. 7, and at the next half-revolution of the machine, or when the crank again reached the position shown in Fig. 2, the form-rollers shown at the top of the printing-bed would have changed places with those on the ink-cylinders.

The construction of the form rollers is best shown in Fig. .1, in which 23 and 39 are steel arbors extending through claws 22 22, having the roller composition 41 cast upon their centers and carrying wheels 24 24, held in position by nuts 25 25. As these formrollers roll around the printing-bed on tracks 26 26 the wheels roll off this track into contact with disks fastened on the end of the ink-cylinder arbors,which are numbered 28 28 28 28 and are best seen in Fig. 1 of the drawings. These disks 28 rotate in such manner that they come into the path of the roller-wheels 24 at a certain portion of their revolution. Each cylinderhasdisksatitsextremeends. Thedisks are the same diameter as the cylinders, and as each set of the form-rollers pass around the bed they overtake one of the cylinders to take ink, the operation being such that the cylinders as a whole make one revolution to the form-rollers as a whole making one revolution. Cylinder 30is arranged to supply ink to form-rollers 41 41 on arbors 23 and 38,\vhile cylinder 29 supplies 41 41 on arbors 23 38. At every revolution of the machine a set of form-rollers will overtake its supply-cylinder at the lowest position shown in Fig. 2. The location of the centers of the form-roller-carriage gears and the centers of the ink-cylinder frames not being in line, but being arranged one below the other, as shown in Fig. 10, the sweep of the form rollers moving around the printing-bed being greater than that of the ink-cylinders, consequently the form-rollers move faster than the cylinders. After the form -rollers leave this position they roll off the cylinder. At the time the machine is making an impression the formrollers are horizontally in line with each other, the cylinders being parallel, but the center of the movement of each is wide apart. It will be seen, therefore, that in order for the form-rollers to have reached the positions shown in Fig. 7 away from the cylinders each set must gain or lose upon its own cylinder as they come to or move from the position shown in Fig. 2. Thus during the operation of the machine theset of form-rollers 41 41 on arbors 39 and 40 take their inksupply from cylinder 30, as shown in Fig. 2, and then pass on and roll ove-r'the face of the type, thereby inking the same, while at the same time the alternating set of rollers will be taking ink from cylinder 29 preparatory to inking the type in their turn.

Sleeve 43 in Fig. 8 has formed at one enda gear 43', also shown in Fig. 9. As this sleeve 43 is rigidly held in the printing-bed, gear 43 is fixed and cannot revolve. Revolving on this sleeve 43 are placed two frames 36 and 37. These frames are tied together and rigidly connected by rods 42 and 58. On frame 36 is fastened a gear 35, and through this gear rod 42 extends, firmly fastening it to frame 36. Frame 37 is slightly different from frame 36, inasmuch as it carries in addition two gears 64 64, fastened on the frame to mesh with fixed gear 43. On the arbors of the cylinders 29 and 30 are also fastened gears 65 65, also meshing with gears 64 64. Now it will be seen that if these two frames 36 and 37 are revolved on shaft 43 and if gear 43 is fixed the gears 64 64 will rotate around gear 43 and revolve the cylinders 29 and 30. At the extreme ends of the cylinder-arbors are fastened the disks 28 28 28 28, described under head of printing-bed proper.

I have purposely shown how the motion is transmitted from gear 31 on journalT through the gears 32 34 to the inside of the printingbed in order to drive the gear 35 and frames carrying the ink-cylinders.

In Fig. 9 I have shown the cylinders 29 and 30 and distributing- rolls 56 and 57. These rolls are made from roller composition. 55 is the metal distributing-roll, (shown best in Fig. 8,) mounted on a fixed arbor 59, which extends from frame 36 to frame 37. Roller-composition distributing- rolls 56 and 57 are cast upon arbors 60 and 61, said arbors being carried in stocks 62 62, made adjustable in frames 36 and 37 and held in posit-ion by adjusting-screws 63. 63. A further description of this method of holding, &c. is not required, as they can be held in any well-known manner. It is simply necessary that the distributing-rolls should make contact between the cylinders 29 and 30 and the metal distributing-roll 55.

As the cylinders 29 and 30 rotate around the fixed gear 43 in the direction indicated by the large arrow in Fig: 9 they are given a rotary motion through the medium of the gears 64 and 65 in the direction of the arrow marked on eachcylinder. As their peripheries come in contact with the composition rolls 56 and 57 these rolls will receive motion in the direction as the arrows indicate and in their turn contact with the distributing-roll 55 on the arbor 59. The means illustrated to obtain the lateral motion of this distributing- I have shown no gearing for giving this distributin g-roll a positive motion, although this is sometimes necessary and is used on my machine, as such mechanism to produce such motion is well known to those familiar with this branch of manufacture. Y

The distributing-roll 55 is the first roll to receive ink from the ink-supply, and in Fig. 7 distributing-roll 55 is shown in the act of receivingthe ink from roll 14. The ink, being received by 55 at every other revolution of the machine, is carried to the distributingrolls 56 and 57 and then in turn given to the cylinders 29 and 30, any surplus on one cylinder being equalized by the action ofv these rolls before it-is taken on the form-rollers.

In7c-supply.0n shaft U in Fig. 1 are fastened two arms 10 and 11. Extending through bearings on these arms is the roll 13, carrying at its extreme end a small wheel 16 andv just inside of this wheel a gear 15. The roll 13 is made of metal, and running in contact with said roll is the composition roll 14, cast upon arbor 51 and also having bearings in the arms 10 and 11. Fastened on I-beam S is a standard 12, extending upward and terminating in a sleeve through which. shaft U passes, and on this sleeve is out a gear 67. (Shown plainly in Fig. 7.) Beside the gear in Fig. 1 on sleeve 12 is shown a cam-slot 68, set obliquely and in which the wheel 16 travels. The function of the gear 67 is such that as it is fixed while the shaft U rotates and carriesthe arms 10 and 11 with rolls 13 and 14 the gear 15 on roll 13 will be caused to rotate as it rolls around the gear 12. The rotary motion thus imparted to roll 13, which is in contact with the composition roller .14, causes roller 14 also to rotate in the direction indicated by the arrow shown in Fig. 7. As the shaft U carries the roll 14 around it will at each revolution be brought into contact with the ink-fountain roll 53 in fountain 52, which is fastened on the I-beam S. At each revolution as the roller 14 touches the fountain-roller 53 it will take therefrom as much ink as the scraper 69 allows to escape, and owing to the continued motion and contact between rollers 13 and 14 the ink will be distributed on the two. As the rollers 13 and 14 are carried around with the shaft U the roll 13 .will be moved laterally upon the surface of roll 14 by the action of wheel 16 following the cam-slot 68 and distributing the ink. At every other revolution of the machineas the roller 14 is brought over the cen ter of the shaft U it comes into contact with and then recedes from the distributing-roller 55, the reason for this occurring at only every other revolution of the machine being that the roller 14 is carried around the shaft U once every revolution of the machine, while the distributing-roller 55 is carried around its central sleeve 13 once every two revolutions of the machine. As 14 and 55 come into contact ink is received from roller 14 and distributed and transmitted to the ink- cylinders 29 and 30.

I have shown the roller 14 delivering the ink to the distributing-roller 55; butI do not limit myself to just this arrangement, as by adjusting the machine I can deliver ink to the rolls of each set of the form-rollers at every revolution of the machine, although the arrangement shown is clearly sufficient to supply the cylinders with all the ink that is needed. If more is required, the latter adjustment or its equivalent can be made.

It will be seen that my printing-bed is made to reciprocate and all parts connected thereto are moved with it; but I do not confine myself to the reciprocating bed, as it could be arranged to oscillate equally as well.

I wish it understood that I do not claim anything shown in patents for bed and platen presses, No. 168,635, dated October 11, 1875; No. 255,704, dated March 28, 1882, and No. 260,792, dated July 11, 1888, as these inventions are based upon fixed printing-beds with moving platens.

Having therefore described my invention, what I claim, and desire to secure by Letters Patent, is

1. In a printing-machine, a vertically-reciprocating frame, a printing-bed carried by the frame and formed with fixed journals at each end, revolving frames journaled on the fixed journals of the printing-bed, one or more ink-cylinders and distributing-rollers journaled in the printing-bed, and form rollq ers in the arms of the roller-carriage frame arranged to contact with the ink-cylinders and be carried over the printing-bed in their revolution.

2. In a printing-machine, the combination with a reciprocating frame, a printing-bed carried by the said frame and around which form-rollers revolve, and ink-cylinders and distributing-rolls rotating and revolving inside the bed, of a rotating revolving roller taking ink from an ink-fountain with a rotary motion and coming into contact in the path of its revolution with one or more of the inkcylinders to supply ink thereto.

3. In aprinting-bed, a combination of shaftcarrying frames in which revolve rolls; said rolls being carried around the shaft by the frame and rotated upon their arbors by contact with a fixed gear, in combination with an ink cylinder or roll against which they roll in contact as they swing around to carry and supply ink to a rotary inking mechanism, substantially as and for the purposes stated.

4. In a printing-machine, a combination of a rotatable inking-surface, printing-bed with journals formed thereon in such a manner that frames revolve on each journal; said frames carrying form-rollers and one of said frames carrying a gear which transmits power through pinions and shafts to the inside of the printing-bed in such a manner as to 1'0 tate the inking-surface to supply ink to the form-rollers which rotate completely around the whole described mechanism, substantially as and for the purposes stated.

5. In a'printing-machine, the combination of a printing-bed supported on slides all being arranged to reciprocate by connection to a crank-shaft, with form-rollers frames on journals formed on the printing-bed and said frames geared to a horizontal shaft that is carried with the bed and receives a rotary motion through a pair of gears fastened to and moving with the bed, substantially as and for the purposes stated.

6. In a printing-machine, the combination of a printing-bed, a suitably-journaled vertical shaft, means to rotate said shaft, a sliding bevel-gear on the vertical shaft, a shaft j ournaled across the reciprocating-bed frame, and a beveled gear on the said shaft, substantially as and for the purpose specified.
