SPECIFICATION forming part of Letters Patent No. 558,480, dated January 21, 1896; Application filed April 6, 1893. Serial No. 469,324. (No model.)

To all whom it may concern: to coact with the form-bed in one direction,

Be it known that I, HENRY AJVISE XVOOD, and the impression cylinders of each pair 5 a citizen of the United States, residing at New might be termed double single printing- York, in the county of New York and State of cylinders.

This looping-roller 40 may be Each of the cylinders of each of the pairs is mounted in arms 41, which arms ll may be IO 5 adapted to be raised and lowered so as only journaled or fixed on the shaft 42, and these arms 41 carry rollers 43, which bear on the cams 44, which are mounted on the shaft 45, and this shaft 45 may be geared to turn at the same speed as the shaft 18, but in the opposite direction. The rollers 43 may be kept against the cams 44 by means of springs 46, which are arranged between the arms 41 and a stationary point, as shown. The web after passing around the looping-roller 40 is then led in through the bite of the continuouslyrunning delivery-

rollers

47, 48, and 49, and is continuously delivered from the press.

The inking mechanism for the press may be arranged as followsz. A fountain is arranged at each end of each bed, as shown, as

the fountain H and H at the ends of the bed A and the fountain H and H at the ends of the bed B. These fountains may have the usual rollers 50, and ink may be conveyed from the fountains to the drum-cylinders 54 mounted at each end of each of the beds, as shown. Ink may be conveyed from the fountain-rollers to the drums 54 by any suitable meansas, for example, by means of the vibrating rollers 51 mounted in arms 52, which may deposit ink upon the rollers 53, and these rollers 53 may convey the ink directly or indirectly to the drums 54, as by means of the composition rollers 55, and also the drums 54 may have suitable distributer-rollers, as 5.50, coacting therewith.

Between the impression-cylinders D and E are arranged the form-rollers 57 and 58 and the distributer-roller 56, and between the impression-cylinders F and G are arranged the form-rollers 60 and 61 and the distributer 59, these form-rollers and distributer being mounted in the carriage C in any of the usual manners.

The impression-cylinders are arranged substantially as shown in the Kidder patent before referred to, so as to print only one way, and so as to run idle or not in contact with the forms the other way. This may be done substantially as shown in the Kidder patent before referred to.

The shaft (Z of the cylinder D may be mounted eccentrically in bushings K j ournaled in the carriage O, and the shaft 6 of the impression-cylinder E may be mounted eccentrically in bushings K journaled in the carriage O, and these bushings K and K may have extending arms 62 and 63, as shown, which may be connected together by means of suitable arms 64, and the whole may be arranged to strike against 1 screws 66 j ournaled in fixed projections when the cylinders are in the left-hand position, and against screws 68 tapped in fixed projections 67 when the cylinders are in their right-hand positions.

The shaft f of the impression-cylinder F may be mounted similarly in bushings L journaled in the carriage, and the shaft g of the impression-cylinder G may be also mounted eccentrically in bushings L journaled in the carriage, and these bushings may have extending

arms

74 and 75, which may be connected together by the connections 76, and these eccentric bushings L and L may be thrown or actuated by means of screws tapped in fixed projections 69, and by means of screws '7 2 tapped in fixed projections 71.

It will be seen that the impression-cylinders D and E are arranged oppositely in the bushings, so that one impression cylinder will be raised as the other impression-cylinder is lowered, and vice versa; also, it will be seen that the impression-cylinders F and G are oppositely mounted.

The operation with this improved mechanism is as follows: The parts are shown as just in the central position of their reverse, and the web as being fed around the impression-cylinders by the action of the loopingroller 40, and the form-rollers as taking their supply of ink from the left-hand fountains. Now, when the feed of the web is finished, the carriage will move to the right. The impression-cylinders E and G being raised, the impression-cylinders D and F will be the operative impression-cylinders, and will make impressions on the web as the cylinders move to the right. As the carriage completes its right-hand movement, the impression-cylinders D and F will be raised, and the impression-cylinders G and E will be lowered, and the form-rollers between the cylinders will again receive a fresh supply of ink from the right-hand fountains. By this means it will be seen that a fresh supply of ink will be given to the forms for each movement in each direction of the impression-cylinders,

whereby the forms will be very nicely and simply inked. The carriage will then move to the left and the cylinders G and E will present the web to the forms, and when the parts reach the left-hand extreme the cylinders G and E will be raised and the cylinders D and F lowered, thus completing the cycle or bringing the parts back to the position shown in Fig. 1.

It Will be seen that the stroke of the impression-cylinders can be kept very short, as there is only one cluster of form-rollers used for each bed.

In some cases I contemplate instead of moving the form-roller in front of the operative impression-cylinder to move the same at the rear of the operative impression-cylinder, when the result will be the same except that the inking will take place after the impression instead of before the impression.

I also contemplate placing the cylinders of each set in close relationship and putting inking apparatus at each side of the set of cylinders, when the inking will take place in the ordinary manner, the relationship between the pair of cylinders and the inking apparatus being the same as the relationship between the usual single-impression cylinder and the usual double-inking apparatus.

The operation of the entire printing mechanism is substantially the same as that shown in the patent to Stonemetz before referred to, except that each impression-cylinder prints in only one direction, and returns idle, and a further detailed description of the same is not thought necessary, the other parts operating to manipulate the web in the wellknown manner.

In Fig. 2 I have shown substantially the same arrangement of press except that the two form-beds A and B are arranged over each other, and the web led oppositely through the press, and the only other change being that the carriage has to be made higher, as at O, and that two rollers 291 and 292 have to be used between the two sets of impressioncylinders, as shown. The looping-

rollers

13 and 39 in this modification may be mounted in arms 91, which may be guided vertically, and which may connect by' links 92 to arms 93 pivoted 011 shaft 94:, and the arms 93 may have rollers 95, which bear on cams 96, which are mounted on shaft 97, which may be geared to turn twice for each complete forward and backward movement of the impression-cylinders. The rollers 95 may be kept normally in contact with the cams 96 by means of springs 98, which may be arranged between the arms 93 and a fixed point, as shown; also, it will be seen that in this modification guiderollers corresponding to guide-rollers 20 and 38 of the previous device are not necessary; but with these slight changes in the guiding mechanism for the Web it will be seen that the device operates as before described.

I have only shown in the drawings diagrams illustrating the action of my press; but this will enable any person skilled in the art to construct practical operating presses in view of the Kidder and Stonemetz patents before referred to.

Of course, the details and arrangements will be modified to suit any desired arrangement, and of course the particular arrangement of beds is immaterial to my invention, two of the common arrangements being shown, and there are many arrangements which can be adopted.

The particular feeding mechanism, the inking mechanisms and the details of the parts may be greatly varied and modified by a skilled printing-press designer without departing from the scope of my invention, as expressed in the claims.

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

1. The combination in a printing press of a form bed, two impression cylinders coacting therewith, means for alternately raising and lowering the impression cylinders, whereby each cylinder will make an impression in one direction only, suitable web-guides, and a web-feeding mechanism adapted to draw forward the proper length of web'when the impression cylinders are off the form bed in either direction, substantiallyas described.

2. The combination in a printing press of two form beds, two traveling impression cylinders coacting with each form bed, means for alternately raising and lowering the impression cylinders coacting with each bed, suitable Web guides and a web feeding mechanism adapted to draw forward the proper length of web when the impression cylinders are off the form beds in either direction, sub stantially as described.

3. The combination in a printing press of a form bed, two traveling impression cylinders coactin g therewith, means for alternately raising and lowering the impression cylinders for the purpose described, suitable web guides, the guide between the impression cylinders being adjustable, and a web feeding mechanism substantially as described.
