Referring to the accompanying drawings, We provide a main frame I, on which is mounted a drum or impression cylinder 2, supported by la drum shaft 3, which is mounted in drum shaft bearings 5, as shown in Fig. 2. The dr-um shaft 3 is driven by a drum sprocket 4, which is connected by a drive chain l, or other equivalent means such as gears, with the sprocket 6 on jack shaft 8. Jack shaft 8 at its inner end carries 'bevel pinion 9. A bevel gear I0 on a clam shaft `II is driven by the bevel pinion 9 and in turn drives the cam shaft II. The jack shaft 8 is mounted in bearings I2 and I4, as shown in Fig. 2.

'33 and with the upper pinion racks 34.

I3 and chain I3a from sprocket I3'b on the motor shaft of a suitable motor M.

Referring to Figs. 1 to 5 inclusive, we provide an adjustable cam I5, an adjustable ca/m I6 beneath the cam I5, and cam I1 beneath the cam I6, the `cam I'I being keyed to shaft II and rotatable therewith. as shown in the drawings. A cam follower I8, yas shown in Fig. 3, engages the edge of the cams. We .provide a cam |adjusting screw I9 having ya threaded engagement with an adjusting screw nut 2i), an adjusting screw stop ZI, and an adjusting screw nut 22. Adjusting screw nut 23 is mounted on intermediate cam I6. Adjusting screw nut 22 is mounted on upper cam I5 and adjusting screw step 2I is mounted in bottom cam Il. We provide end springs 24, each having one end secured at 25 to the main frame I and having the other ends of said springs secured at 2.5' to the carriage frame 29. Or any other suitable and equivalent means may be used in place of springs 24 for return of the carriage :frame 2'9 to its original position.

Referring to Figs. 1, 3 and 4, a cam locking screw 26 passes through the elongated adjusting slots 28 in cams I5 and I6 and is secured to the bottom icam I'I. Cam locking screw 26 carries a knurled nut 21 for manual adjustment.

A carriage frame 29 carries spaced rollers 30 which ride on the carriagerails 3I, as shown in Fig. 2. On oposite sides of the machine a lower pinion rack 33 is aiiixed to rail 3l and an upper pinion rack 34 is afxed to a type bed table 35. Like light differential pinions 32, supported by carriage 29, mesh with the lower pinion racks Type bed table 35 rides on rollers 30 and carries the type bed 36 and type 31. As shown in Fig. 2, opposite longitudinally grooved carriage guides 38 receive and guide the ends or hubs of the carriage rollers y3i); the opposite table guides 39 guide the type bed table 315.

As shown in Fig. 2, paper discharge cam 4i) is attached to an upper `cam guide 4I and to a lower cam guide r42. Paper grip lingers 43 are mounted on a shaft 44, supported by the ends of impression cylinder 3, as shown in Fig. 3. Cam operatively engages a cam 40 on gear 45a. A cam gear shaft 45 carries the cam gear 45a, which meshes with the gear 45h which is mounted on the drum shaft 3. The upper cam guide 4I is mounted in a .bearing y46. On the other end of Y rupper cam guide 4I is a collar 4`I which holds Ythe The sprocket jack shaft 8 is driven by a sprocket v55 upper spring 48 in place. Similarly on the outer end of guide -42 is a collar 49 which holds the lower spring 50 in place.

As shown in Figs. 2 and 3, a cam follower arm 5I carries a cam follower 52 which rollably engages the paper discharge cam 40.

As shown in Fig. 3, a sheet 53 to be printed is carried by the drum 2 to receive a series of printing impressions from the type 31 on successive portions of the sheet, such as those designated No. 1, No. 2, and No. 3 in Fig. 9.

In operation, the motor M from motor sprocket I3b, drives the jack shaft 8 by suitable means such as chain I3a and sprocket I3. Jack shaft 8 carries a sprocket 5 which drives a chain 1 and a sprocket 4 on a drum shaft 3 on which a drum or impression cylinder 2 is ailiXed. Drum shaft 3 also carries cam follower arm 5I, which in turn carries the cam follower 52. The jack shaft 8 also carries a bevel pinion 9, which drives bevel gear I attached to cam shaft I I, and thereby rotates the cams i5, I6, and I1, which are mounted on the upper end of cam shaft I I.

Top cam I and intermediate cam I6 are adjustable relative to bottom cam I1 by means of the slots 28 and cam locking screw 26 extending through said slots and the nut 21.

The cams I5, I6, and I1 are made adjustable to provide for variations in the width of the sheets to be printed. The lobes of cams I5, I5, and I1 are designed to operate the cam follower arm I8 which in turn operates carriage 29 and the members operatively connected with carriage 29 to cause a delayed action of the type bed table 35 and its type bed 33 and type 31 to cooperate with successive portions of the drum or impression cylinder at each revolution of same. Inasmuch as the sheets of paper to be printed must be retained on the drum for a predetermined number of revolutions (three in the form of the invention illustrated), the members 4B to 5l hereinbefore described, provide for gripping of the paper prior to the printing and for releasing it after the final impression on the sheet.

Any suitable conventional mechanism may be utilized for feeding the paper to the drum and taking it off of the drum. Any conventional type can be applied to the press.

The cams I5, I6 and I1 are rotated by the shaft II and successively their edges operatively contact with the cam follower I8, as shown in Fig. 3, thereby operating the carriage 29 with a reciprocatory horizontal movement. As the carriage 29 is moved rearwardly its differential pinions 32 ride in the lower pinion racks 33 and also mesh with the upper pinion racks 34 which are attached to the type bed table 35, thereby moving the type bed table 35 and its type bed 36 and type 31 with a horizontal reciprocatory movement in the direction in which the carriage 29 moves.

As the type bed table 35, type bed 35 and type 31 travel beneath the cylinder, a rst impression is made on the portion of sheet 53 designated No. 1 (see Figs. 6 and 9) After the table has traveled beneath the cylinder, it is returned to its position while the drum or printing cylinder 2 carrying sheet 53 is revolving. During this revolution of the cylinder, one of the cams I5, I6, or I1 causes a delay or retardation of the forward action of the table so as to bring another portion of section of sheet 53 (see Figs. 7 and 9) into position for the second impression on sheet 53 at the portion designated No. 2. This operation is repeated the third time, the delayed action bringing still another section or segment of sheet 53 into position above the type 31 for a third impression on sheet 53 on the portion designated No. 3 (see Figs. 8 and 9). After this operation the sheet 53 is removed from the drum 2 by conventional means, and a new sheet inserted.

While only three impressions on a sheet are illustrated and described, the device might be made for printing any suitable number of impressions on a sheet by providing an appropriate or desired number of cams for causing delayed actions of the carriage frame and type bed table for each impression to be printed on the sheet. It is apparent that by use of such mechanism a single form of type can make an indenite number of impressions on different sections of a sheet of paper without taking same from the printing cylinder. This will reduce the hand or automatic feeding of stock through the press and greatly expedite printing.

As illustrated in Figs. 4 and 5, the relative position of cams I5, I6 and I1 may be readily adjusted by means of screws 23 and 26 for longitudinal and lateral adjustment respectively.

As shown in Fig. 3 a series of paper grip fingers 43 mounted on shaft 44 grip the forward edge of the sheet to be printed and at the appropriate time release it. Paper discharge cam 40 operating as shown in Fig. 2, controls the cam follower arm 5I and causes the latter at the proper time to actuate the paper grip fingers 43 to release the forward edge of sheet 53 to discharge same from the drum after all the sections of the sheet have been printed. The cam 40 is normally held in contact with the ends of bearings 46 by the tension of springs 48 and 50, thereby holding it disengaged from arm 5I and leaving arm 5I in a nonoperative position. The rotation of cam member 40 moves cam 49 toward the drum 2, where it is engaged by cam follower 52 and thereby actuates member 5I, which in turn releases the paper finger grips 43 from their engagement with the forward edge of the paper sheet 53 to discharge same from the drum.
