PRINTING-PRESS.

Specification of Letters Patent.

Patented Aug. 8, 1905.

Application filed March 30, 1904. Serial No- 200,850.

To aZZ whom it may concern.-

Be it known that I, WILLIAM M. CLARK, a citizen of the United States, residing at Philadelphia, county of Philadelphia, and State of Pennsylvania, have invented certain Improvements in Printing-Presses, of which the following is a specification.

This invention is more particularly designed to provide improved mechanism particularly adapted for job-printing, in which are combined the cylinder-printing principle with the convenient job-press design. It provides a press which is simple and strong in construction, rapid and easy of action, capable of being produced at a small price, and well adapted not only for the class of work done by all job-presses, but also for half-tone work, em-

bossing, and the finer grades of printing not usually capable of being produced upon the job-press. It is also designed for web-feeding, automatically cutting and delivering the printed sheets, and for the operation of numbering and counting mechanism.

The nature and characteristic features of the improvements will more fully appear by reference to the following description and the accompanying drawings in illustration thereof, of which Figure 1 represents a side elevation of a printing-press embodying the invention. Fig. 2 represents a rear elevation of the press. Fig. 3 represents a sectional view taken on the line 3 3 of Fig. 2. Fig. 4 represents a sectional view taken on the line 4 4 of Fig. 1. Fig. 5 represents a sectional view taken on the line 5 5 of Fig. 1. Fig. 6 represents a sectional view taken on the line 6 6 of Fig. 3. Fig. 7 represents a sectional view taken on the line 7 7 of Fig. 3. Fig. 8 represents a side elevation of the feeding and cutting mechanism opposite to that shown in Fig. 1. Fig. 9 represents a top plan view of the feeding and cutting mechanism. Fig. 10 represents a sectional view taken on the line 10 10 of Fig. 9. Fig. 11 represents a sectional view taken on the line 11 11 of Fig. 9, and Fig. 12 represents an end elevation of the feeding and cutting mechanism.

As shown in the drawings, the frame 1 has journaled therein the shaft 2, which has fixed thereon the driving-wheel 3 and the pinions 4. These pinions engage and drive the spurwheels 5, fixed on the spindles 6, which are journaled in the frame and have fixed thereon the cams 7. Riding on these cams are the rollers 8, which revolve on the journals 9, ec-

centrically fixed by the disks 9 to a shaft 10, journaled in the frame-shoes 11 and rocked by the lever 12, the shoes having the pivotal connections 13 with the frame and being rocked thereon by the cams 7 through an arc variable by changing the position of the rollers 8, carried by the movable journals 9.

A pressure-segment or cylindrical platen 14 has the radial arms 15, which carry a rod 16, having rollers 17 thereon adapted to pivot and run in the guides or ways 18 of the shoes, the rod being connected by the links 19 with the crank-pins 20 of the spur-wheels 5, by which the platen is rocked. The rocking movement of the platen is controlled by the links 21,

having the pivotal connections 22 with the platen and the pivotal connections 23 with the frame. The links 21 have the pivotal connections 27 with the links 25, and the latter have the pivotal connections 26 with the arms 29, pivot-ally supported in the frame by the rod 28. The arms 29 carry the ink-roller 30, adapted to oscillate in contact with a typeform 31, held by the chase 32 upon a bed 33, the bed being connected with the support 34 by the screw 35.

Rocking with the rod 28 is a finger or projection 36, adapted to engage a lever 37, having the fulcrum 38 and carrying a gravitypawl 39, the latter being adapted to engage a circular rack 40 on the'under side of the inkdistributing disk 41, which has the journal 42 bearing in the supporting member 43.

Journaled on the frame is a paper-roll 44, from which the paper 45 is drawn over the rollers 46 and 50 between the type-form and the platen. s The paper is carried thence over the table 49, through the guides 51, between the rollers 52 and 53, and beneath the presserarm 54 and the knife 55.

The roller 53 has the ratchet-wheel 56 fixed thereon and actuated by a knife-pawl 57, fixed in relation to a pinion 58, adapted to rock upon the shaft 59, which carries the roller. The pinion is rocked by the engagement therewith of the segmental spur 60, journaled on the spindle 61 and rocked by the link 62, connected with the crank-pin 63 on the segmental spur. The link 62 is journaled on a crankpin 64, fixed on a graduated slide 65, having the slot 66, through which a set-screw 67 passes, being fixed eccentrically in relation to the axis of a cam 7, by which the length of feed is regulated. The other cam 7 has eccentrically fixed in relation thereto a boss 71, which is adapted to engage and rock a lever 72, having the fulcrum 73. This lever has the pivotal connection 74. with a link 75, which has the pivotal connection 76 with the knife 55, the latter having the fulcrum 77 and being elevated by the spring 78. The presserarm 54 has the fulcrum 79 and is held elevated by the spring 78, being depressed by the spring 80 to engage and hold the paper when the depression of the knife effects the depression of the spring 78.

It will now be understood that the revolution of the driving-shaft 2 effects, through the gears 4 and 5, the revolution of the shaft 6 and cams 7 and the reciprocation of the links 19, by which the guiding-shoes 11 and the platen 14 are reciprocated, the cams acting, through the rollers 8, to elevate the shoes, so that the guides 18 and the links 21 cause the platen to roll upon its bed or type-form in the printing movement and to drop the shoes, so that the guides cause the platen to be withdrawn from the bed on the return movement. As the ink-roller 30 is connected with the links 21 by the links 25 and arms 29, it will reciprocate on the type-form 31 in unison with the action of the platen. By moving the lever 12 and revolving the journal of the eccentrically-mounted rollers 8 the rise of the shoes may be limited, so that the platen will not be thrown in contact, but will reciprocate out of contact with the type-form.

Simultaneously with the reciprocation of the platen the cams 7 eflect the intermittent feeding and cutting operations in alternation, the paper being advanced as the platen returns and the cutting being effected simultaneously with the printing movement. The feeding operation is effected by the reciprocation of the link 62, segmental gear 60, spurgear 58, and pawl 57, rotating the roller 52, by which the paper is advanced. The cutting operation is effected by the depression of the lever 72, the link 75, and knife 55 against the action of the spring 78, the holding device 54f being depressed by the spring 80 to hold the paper as the knife descends.

By referring to Figs. 1 and 3 of the drawings it will be seen that the upper part of the curved face of the platen during its downward or return movement gradually approaches a horizontal position, whereby to permit a ready feeding and removal of the sheets to be printed. Thus this design of press has all the feeding advantages of the ordinary flatbed and platen presses, and at the same time it has the further impression advantages of the cylinder-press, the latter being due to the curved platen.
