T or whom it may concern:

Beit known that we, JOHN WARREN SMITH and GEORGE UPTON HARN, Jr., citizens of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented a certain new and useful Improvement in Printing-Machines, of which the following is a specification.

This invention relates to printing-machines, and is designed to provide an improved machine of this character which is arranged for printing upon a continuous strip as it is fed from a roll and to cut the strip into sections aftereach printing-impression has been made, and it is particularly designed for printing the daily Weather Bureau bulletins of the forecast of the weather.

Another object of the invention is to provide improved means for inking the printingroll, whereby the ink will be properly and uniformly distributed upon the type and surplusage ofink is edectually obviated. In this connection it is designed to provide for intermittently supplying ink from the ink-reservoir to the ink-distributing means and to bring about this intermittent feed of the ink automatically by the general operation of the machine.

A still further object of the invention is to prevent tearing and damage to the paper when the latter is being cut into sections and also to provide for carrying the out sections away I from the cutting apparatus at a greater rate of speed than the paper is fed to the printingroll, thereby to obviate choking of the machine.

With these and other objects in view the present invention consists in the combination and arrangement of parts, as will be hereinafter more fully described, shown in the accompanying drawings,and particularly pointed out in the appended claims, it being understood that changes in the form, proportion, size, and minor details may be made within the scope of the claims without departing from the spirit or sacrificing any of. the advantages of the present invention.

In the drawings, Figure 1 is a side elevation of a printing-machine constructed and arranged in accordancewith the present invention. Fig. 2 is an elevation of the opposite side of the machine. Fig. 3 is a longitudinal sectional view of the machine. Fig. 4 is an enlarged detail side elevation, parts of the frame being broken away to show the means for intermittently supplying ink to the distributing apparatus. Fig. 5 is a detail sectional view taken on the line 5 5 of Fig. 2 to show the connection between the main frame and the supplemental frame for the support of the inking apparatus. Fig. 6 is a detail perspective view of one of the rolls included in the delivery device. Fig. 7 is an enlarged detail sectional view taken through the paper-guide.

Like characters of reference designate corresponding parts in all the figures of the drawings.

. For the support of the operating parts of the present machine there is provided a main frame, comprising opposite side members 1 and 2, respectively, which have suitable legstandards and are connected in any preferred manneras, for instance, by cross-bars 3. (Best shown in Fig. 3 ofthe drawings.) About the middle of the frame and disposed transversely below the top thereof is aplaten in the form of an impression-r0114, which is suitably journaled in the opposite side members of the frame. Above the impression-roll and in cooperative relation therewith is a printing-roll 5, which will be hereinafter described in detail, said roll also being journaled in the opposite sides of the main frame. One of the journals of the impression-roll'is projected at the exterior of the main frame and is provided with a belt-wheel 6, (shown in Fig. 2,) to which power is applied for operating the machine. I

In front of the printing-roll there is a transverse shaft or roller 7, which carries a paperroll 8. The free end of the paper passes rearwardly from the paper-roll and between the printing and impression rolls, there being suitable feedrolls 9 disposed transversely of the machine and located between the paperroll and the printing-roll, with the paper passed between said feed-rolls and thelatter in frictional contact therewith, so as to draw the paper from the paper-roll.

Immediately in rear of the printing-roll is the paper-cutting apparatus, comprising upper and lower rolls 10 and 11, respectively, of which the lower roll is provided with diametrically opposite longitudinal grooves in which are fitted wooden strips 12, that are flush with the periphery of the roll, while the upper roll is provided with diametrically opposite longitudinally-disposed sets of cutting-teeth 13, which are adapted to register with the respective wooden strips and bite into the latter, so as to sever the paper strip into sections after the printing impression has been made. The paper is guidedand supported when passing toand from the cuttingrolls by means of a frame comprising upper and lower substantially horizontal plates 14 and 15, respectively,which are disposed transversely in the space between the rear faces of the printing and impression rolls and terminally supported by the opposite side members 1 and 2 of the main frame. These two plates are separated by a space just sufficient to receive the paper and are located as close as possible to the printing and impression rolls in order that the paper may positively enter between the plates as soon as it leaves the printing and impression rolls, the lower of said plates being wider than and projected in rear of the upper plate. Carried by these plates and projected rearwardly therefrom between the cutting-rolls 10 and 11 are substantially horizontal wires 16 and 17, preferably three for each plate, as indicated in Fig. 13 of the drawings, with their rear extremities rebent across their upper and lower sides, respectively, and coiled about or otherwise secured to transverse wires or rods 18 and 19, respectively. As clearly shown in Fig. 3, the plates 14 and 15 are at the front side of the cutting-rolls and the transverse rods 18 and 19 are in rear of said rolls, the

latter being provided with registered peripheral grooves 20, as shown in Fig. 12, forthe reception of the wires 16 and 17.

For carrying 01f the slips after being cut from the paper strip there is provided a delivery apparatus embodying upper and lower sets of rolls 21 and 22, one of which has been vent choking of the cutting apparatus, it is As the paper,

graduated train of idlegears 27, mounted upon the adjacent frame member and extending between the gears 25 and 26, whereby the rolls of the conveyer are driven at a greater rate of speed than the belt-wheel, which is carried by the impression-roll. The cuttingrolls are also driven from the impression-roll, as will be understood by reference to Fig. 1 of the drawings, wherein it will be seen that a gear 28 is carried by that journal of the impression-rollwhich is opposite the belt-wheel 6, from which it will be understood that the gear 25 and the belt-wheel 6 are upon one side of the frame and the gear 28 is upon the opposite side thereof. The journals of the cuttingrolls are provided with meshed gears 29 and 30, respectively, of which the lower gear 30 is in mesh with anidle gear 31, mounted upon the frame and in turn in mesh with the gear c.

28. It will here be noted that the cutting apparatus and the conveyer or delivery apparatus are both driven from the same source that is to say, from the impression-rollbut it will be understood that the conveyer is geared to the impression-roll so as to run at a greater rate of speed than the cutting-rolls, wherefore it is obvious that the out slips will be carried off faster than the paper strip is fed to the cutting-rolls, and hence choking of the latter is effectually obviated.

The apparatus forinking the printing-roll embodiesa supplement-a1 frame having opposite side members 33 and 34, each of said members having its lower edge fitted in a groove or Way 35, formed in the upper edge of the adjacent side member of the main frame, as best shown in Fig. 5 of the drawings. Suitable set-screws 36 pierce the outer wall of each groove or way and engage the adjacent side member of the supplemental frame to adjustably hold the latter in place. By this means the supplemental frame may be conveniently slid into position from the front of the machine and then adjusted to locate the inking apparatus in proper relation with respect to the printing-roll. The inking apparatus is made up of a plurality of rolls embodying a pair of inkingrolls proper, 37 and 38, which are located one above the other and in contact with the periphery of-the printing-roll, as best shown in Fig. 30f the drawings, said rolls being journaled in the sides of the supplemental frame. In front of and in contact with the inking-rolls is a distributing-roll 39, journaled in the supplemental frame, and in front of the distributing-roll and slightly above the same is a feed-roll 40 in contact with said distributing-roll. The ink box or reservoir proper, which has not been shown in the drawings, is carried by a holder 41 in the form of asubstantially rectangular frame having its top, bottom, and inner sides open and within the lower portion of which is journaled an agitating-roll 42, that is normally out of contact with the feed-roll 40. Within the holder 41 is a scraper-plate 43,

the lower edge of which is normally in contact with the agitating-roll and is capable of adjustment by means of one or more setscrews 44, that pierce the front side of the holder and bear against the scraper-plate.

The rolls of the inking apparatus are driven from the feed-rolls 9, and the latterare driven from the main gear 25, as shown in Fig. 1. The journals of the feed-roll 9 are provided with meshed gears 45 and 46, the lower of which is in mesh with an idle pinion 47, mounted upon the main frame and in mesh with the gear 28. Above the pinion 47 and in mesh therewith is another pinion,48,which is in turn in mesh with a gear 49 upon the adjacent journal of the printing-roll. At the outer side of the gear 45 is a belt-wheel 50, over which runs an endless belt 51, which in turn runs Over a belt-wheel 52 upon the adjacent journal of the distributingroll 39. Said journal is provided with a gear 53, located at the inner side of the supplemental frame and in mesh with a larger idle gear 54 in rear of the distribnting-roll and upon the supplemental frame. A cam or eccentric 55 is carried by the gear 54 and forms a tappet for engagement with the lower arm of an angle or bell-crank lever or bracket 56, intermediately pivoted upon the supplemental frame. The feed-roll 40 is journaled upon the upper arm of this bracket, and a similar or suitable swinging bracket is employed for the support of the opposite journal of the feed-roll, whereby it will be understood that the feed-roll normally gravitates into frictional contact with the distributing-roll, and is thereby normally out of contact with the agitating-roll. It will here be not-ed that the lower end of the bracket 56 lies in the path of the cam or tappet 55, whereby the eccentric portion of said cam regularly engages the bracket and tilts or rocks the same to throw the feed-roll 4O upwardly and forwardly away from the distributing-roll and into contact with the agitating-roll 42. At the same time a dog or pawl 57, carried upon one of the journals of the distributing-roll, engages with the teeth of ratchetdisk 58 upon the adjacent journal of the agitating-roll, whereby the latter is rotated and wipes across the feed-roll to supply ink thereto. When the eccentric portion of the cam leaves the tiltable bracket, the feedroll gravitates back into engagement with the distributing-roll, whereby ink is intermittently supplied to the feed-roll in an automatic manner.

In the present machine the printing-roll is provided with fonrelectrotypes to impress a uniform heading four times upon the paper at each rotation of the printing-roll, the spaces between the electrotypes carrying the changeable subjectmatter to be printed upon the paper, and therefore it will be understood that four duplicate impressions are made at each rottaion of the printing-roll. In this connection it will of course be understood that the cutting-rolls are geared to rotate twice as fast as the printing-roll in order that they may properly cut the paper into separate slips after each impression is made.

It will be noted that the cutting-knives 13 are made up of a plurality of points or teeth, which perforate the paper, and in view of the fact that the delivery apparatus runs faster than the paper is fed to the knives it is apparent that the delivery apparatus is an element of the cutting apparatus, as the increased speed tends to tear or sever the paper along each line of perforations.

What is claimed is- 1. In a printing-machine of the character described, the combination with cooperating printing and impression rolls, of paper-cutting apparatus comprisinga supporting-roll, and a knife-roll, one of said rolls having peripheral grooves, upper and lower plates disposed between the printing-roll and the cutting apparatus, and rods carried by the plates and projected through the grooves of the grooved roller.
