PRINTING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 668,807, dated February 26, 1901'.

Application filed December 31, 1897. Serial No. 665.031. (No model.)

To a/ZZ whom, it may concern:

Be it known that I, WILLIAM SPALCKHAVER,

a citizen of the United States, residingat Brooklyn, county of Kings, and State'of New York, have invented certain new and useful Improvements in Printing-Machines, fully described and represented in the following specification and the accompanying drawings, forming a part of the same.

This invention relates to printing machines, and has been designed especially with a view of providing a machine for taking proof impressions.

The invention aims especially to provide an t5 improved construction whereby thelength of the web advanced for each impression and thelengtli of the printed sheet are made to correspond with the length of the form.

As a full understanding of the invention zo can best be given by a detailed description of a preferred construction embodying all the features of the invention, allpreliminary description will be omitted, and such a detailed description will now be given in connection z5 with the accompanying drawings, showing such a preferred construction, and the features forming the invention will afterward be speciiically pointed out in the claims.

In said drawings, Figure l is a side view of 3o a bed-and-cylinder printingmachine conf structed to embody the invention. Fig. 2 is an end view looking in the direction of the arrow 2 in Fig. l and parts being shown in section on line 2 of Fig. 1. Fig. 3 is an enlarged longitudinal sectional View of the impression cylinder and coacting parts and partly taken on line 3 of Fig. 4. Fig. 4 is a detail plan view showing the form-lock and associated parts. Fig. 5 is a View, partly 4o diagrammatic, of the im pression-cylinder and `coacting parts taken just inside the frame looking in the direction of the arrow in Fig. 2. Fig. 6 is a side View of some of the parts shown in Fig. 5, but in a different position. Fig. 7 is a plan view ofthe parts shown in Fig. 6. Fig. 8 is a detail section on the line 8 of Fig'. 4. Fig. 9 is adiagrammatic View of the impression-cylinder,the web-feeding devices,

thereon in positionjust before the beginning 5o of an impression. y

Referring to t-he drawings, the various op'- erating parts of the machine are su pported in a suitable frame A. The form bed B is mounted to reciprocate horizontally on supportingrolls 10, being guided by groo\es 11 in the side frames, as shown in Fig. 2. The bed is reciprocated by means ofr two endless sprocket-chains 12 13,-turning at one end of their run on sprocket-wheels 14, mounted 6o on studs extending inwardly from the side frames, and at the other end on driving sprocket-wheels 15, carried by short shafts 16, each of which shafts 16 carriesa pinion 17, meshing with a gear 18 on the driving-shaft 65 20, Connected to a link of each of the sprocket-chains 12 13 is a driving-pin 21, which carries a box 22, mounted to ride in a vertical groove or guideway 23, formed in a hanger 24, carried by the bed. By this con- 7o struction as the sprocket-chains are driven by the driving sprocket-wheels 15 they will through the pin 21 and box 22 move the bed in one direction or the other, according as the links carrying the pin 21 are travelingin the 75 upper or lower path of the sprocket-chains. As the links carrying the driving-pin arrive at the driving sprocket-wheels after having moved through the upper path of the chains to the left in Fig. 1, as indicated by the ar- 8o row,and move downward around the sprocketwheels the driving-pin and box 22, moving with said links, slow down, and then stop the movement of the bed to the left in Fig. 1 as the box moves downward in the slot 23 of the 85 hanger 24, and then start and accelerate its movement to the right, and then as the pincarrying links leave the sprocket-wheels 15 the bed will be moved at a uniform speed to the right until the pin-carrying links reach 9o the sprocket-wheels 14, when the movement of the bed will be gradually decreased, stopped, and then started and increased in the opposite direction as the pin-carrying links turn upward about the sprocket-wheels 14, carrying the box 22 upward in the slot 23. Then the bed will be again moved at a uniand the front portion of the bed, with a form 1 form speed to the left.

The impression-cylinder C is journaled in journalboxes 25, mounted to reciprocate vertically in standards 26, extending upward from the frame A at either side of the machine, which journal-boxes 25 are lowered to hold the cylinder C in printing position when the bed is being moved to the left in Fig. l and raised to elevate the impression-cylinder during the return movement of the bed. The journal-boxes 25 are thus raised and lowered by means of cams 27, carried by the camshaft 28, one at either side of the machine, through pitmen 29, pivoted one to each journal-box and having forked ends embracing the ends of the shaft 28 and carrying rolls running in the cams 27. The cam-shaft 28 carries a gear 30, meshing with a pinion 31 on the driving-shaft 20, these gears being of proper relative size to cause the cam-shaft 28 to make one revolution t0 each complete reciprocation of the form-bed B, and the cam 27 being formed to give the desired movements to the journal-boxes 25. The impression cylinder C is driven so as to rotate at a surface speed corresponding to the movement of the bed during its printing movement by means of a rack 32, carried by the bed, and a gear 33, carried by the cylinder.

The roll of paper WV is supported by the upper ends of the standards 26, an adjustable tension-band 34 being preferably provided to bear on a tension-disk 35 on one end of the shaft carrying the web-roll. The web is led from the web-roll past a guide-bar 40, between feeding-

rolls

41 and 42, over a guide 43, and between cutting-

blades

44 and 45 to the under side of the impression-cylinder C to be entered between the cylinder C and the form carried by the bed B for printing. The feeding-roll 41 is driven by frictional contact with a driving-roll 46, mounted in arms carried by the journal-boxes 25, said roll being provided with a gear 47, meshing with the gear 33, carried by the impression-cylinder. 'lhe feeding-roll 42 is preferably mounted so as to be adjustable toward and from the feeding-roll 41, as by being carried by eccentrics 48, arranged to be operated through handles 49,and secured by set-screws, as shown clearly in Fig. 1. The feeding-101141 is preferably a rubber-covered roll, as indicated in Fig. 3.

The feeding-

rolls

41 and 42 and the cuttingblade 45 are carried by a frame 50, pivoted on a shaft 51, so that by rocking the frame 50 the feeding-roll 4l may be moved into and out of position to contact with the driving-roll 46, and the cutting-blade 45 maybe moved into and out of position to eoact with the stationary blade 44. The pivot-shaft 51 is positioned between the feedingroll and the blade 45 so that when the frame is rocked so as to bring the feeding-roll 4l in contact with the driving-roll 46 the cutting-blade 45 will be moved away from the blade 44 to allow the paper to pass freely between them and when the frame is rocked to carry the feeding-roll 41 away from the driving-roll. The

blade 45 will be thrown forward to coact with the blade 44in severing the web. This rocking frame is under tension, as by a coiled spring 52, which tends to rock it, so as to hold the feeding-roll 41 in contact with the drivingroll 46; but it is normally held in its nonfeeding position-that is, with the feedingroll 41 out of contact with the driving-roll 46-by means of a pivoted latch 55, having a right-angular slot 56, which engages a pin 57, carried by a downward extension of 011e side of the frame 50. As the bed is advanced to carry the form beneath the impression-cylinder for printing, before the front end of the form reaches the cylinder an abutment formed by a stud or roll 60, carried by the bed, engages the under side of an inclined cam-plate 6l on the latch 55 and throws the lat-ch upward from the position shown in Fig. 6 to bring the horizontal portion of the rightangular slot 56 opposite the pin 57 on the rocking frame 50, thus releasing the frame, which is then rocked by the spring 52 to carry the feeding-roll 41 into contact with the driving-roll 46, as shown in Figs. 1 and 5, thus causing the feeding-rolls to advance the web downward over the guide 43. The position of the abutment 60 longitudinally of the bed is such as to cause the feeding of the web to begin in time so that the forward end of the web will be advanced from the cutting-knives in time to enter beneath the impression-cylinder in advance of the front end ot' the form. As the printing movement of the bed continues,the rocking frame remains in the position shown in Fig. 5 until a cam 62, carried by the bed, engages a stud or roll G3, carried by a link 64, pivoted to the frame 50, and guided by a pin 65, extending from the frame A through a slot in the link. The cam 62 draws the link G4 downward, thereby rocking the frame 50 against the tension of the spring 52 from the position shown in Fig. 5 to that shown in Fig. 3, whereby the cutting-blade 45 is thrown to coact with the blade 45 to sever a sheet length from the web, and the feeding-roll 41 is carried away from the driving-roll 46 to stop the feed of the web, the pin 57 being also brought beneath the vertical portion of the right-angular slot 56 in the latch 55, thus allowing t-he latch to fall and lock the frame in this position. The frame 50 then remains in its nonfeeding position until the web is again to be fed as the bed begins its next printing movement.

In order that thc latch 55 shall not be raised to release the frame on the return movement of the bed, the abutment 6 0 is carried by a pivoted arm 66, normally resting against a stop 67 to hold the abutment 6() in operative position, as shown in Fig. 5, but free to be raised from that position, so that as the bed returns the abutment, engaging the upper side of the cam-plate 61, rides over the cam without moving the latch 55 from its holding position.

It will be seen that the length of the web IOO IIC

fed between the feeding-

rolls

41 and 42 and the length of the sheet cut from the web by the cutting-blades 44 45 depends on the distance between the abutment 60 and the cam 62, carried by the bed, and it is evident that by changing the distance between said abutment and cam, by moving either one or the other, the length of web fed between the rolls 4l and 42 for each impression and the length of the printed sheet may be varied. In the preferred construction shown the distance between the abutment and the cam, and consequently the length of web advanced for each impression, is determined by the length ofthe form, one of said members being arranged to move with the form-lock or movable member by which the form is secured on the bed.

In the machine shown the forward end of the form always occupies the same position, the form being held against a stationary stop 70, and a movable form-lock 7l being provided to engage the rear end of the form, so as to accommodate forms of different lengths. As shown, the form-lock consists of a body portion 72, which runs in a dovetailed groove 73 in the frame at one side of the bed, and an arm 74, which carries a spring-seated bearing-plate 75. The bottom of the dovetailed groove 73 is provided with a ratchet-rack 76, which is engaged by a spring-pressed pawl 77, carried by the form-lock and by which the form-lock is held securely in place when it has been advanced to bring the spring-pressed bearing-plate 75 against the rear end of the form. The cam 62 is carried by an arm eX- tending from a block 78, which is also held and guided in the dovetailed groove 73 and which is connected with the form-lock 71, so as to be moved therewith. The cam 62 will thus be automatically adj usted with relation to the abutment 60, according to the length of the form on the bed.

In order to provide for varying the margin at the end of the printed sheet, the block 78, carrying the cam 62, is preferably adjustably connected with the form, as by the turnscrew 79.

The printed sheets are advanced from between the impression roll and the form through guides 8O and 8l to delivery-tapes 82 and 83. Any suitable inking mechanism may be employed.

It will be understood that the invention is not limited to the exact construction shown for the purpose of illustrating the invention and to which the foregoing description has been mainly confined, but that various changes and modifications thereof may be made Within the claims.
