eccentric must'be a trifle smaller than the opening between said surfaces, to allow movement of said eccentric. A regulator 8 being shown in Fig. VIII is built intwo parts A and B, part A is secured with a set screw to a shaft'lO, nd screws 9 in said'part secure said regulator in connection with part B in a suitable position to said eccentric.

For instance, if the size of a print is 10 nches long, then said eccentric must be set,

to reciprocate said main carrier in said support 5 inches back and 5 inches forward, both movements combined must be 10 inches. Said eccentric is secured to a shaft 10, which is journaled withsuitable hearings in the front and the rear support 3. A gear. 11

secured to said shaft is meshed to a gear 12 which is secured to a shaft 13 secured in duplex hearings in a support 14. Said support is secured in the rear of the machine to the platform 1. The shaft 13 may be driven by a belt passing around the power wheel 15,

to operate the different mechanicalmovements. 7 v

The lower part 'of said" main carrier is a printing platform 16, suitable guides l7 for paper 18 are slidably secured in a rail 19 in said platform to hold any width of paper while running over said platform in a good position. Y

A printing carrier 20 isv reciprocated in a vertical direction on its rails in said main carrier by an eccentric 21, which is operative in an oblong frame 22, between plane surfaces. Said eccentricis secured to a shaft '23, which is journaled with-suitable bearings in the front and the rear support 3.

A gear 24 secured to said shaft is meshed 'to a gear .25 which. is secured to an idle 27 are secured on said frame and a partition of said carrier.v A screw 28, which can be turned in the upper part of said carrier, is to liftor lower said carrier in the main carrier to an adjusted position, to give with said springs the correct pressure for the A type-bed 29 facing downward is secured in suitable rails in the lower part of the printing carrier. The side and a top view of said lower part being shown in Figs. II and III. A suitable ink-table 30 facing upward is secured tothe printing carrier.

Inking rollers 45 -travel once for every operation in a circle around said type bed and said inktable in the direction of the arrows, to ink the type when the printing carrier is at its highest position and to run over the inktable while the type is in printing contact, running at the same speed andin the same direction as the running paper.

The eccentric 21 must be regulated, to lift the printing carrier to a suitable height, to allow said ink-rollers to ink the type without touching the paper, which is running constantly in transverse direction in relation to the inking rollers over the printing platform 16.

Means to transmit the motion causing said inking rollers to travel is shown in Fig.

. II. A bevelgear 32 secured to the shaft 23 is meshed to a bevelgear 33, which is secured to a spiralgear 34. Said spiral gear is secured with suitable bearings underneath the rear support 3 and the platform 1, and is meshed to a pin-wheel 35, which is secured to a shaft 36 journaled with suitable bearings in the rear extension on the printing carrier. Bevelgears 37 secured to said shaft are'meshed to bevelgears 38; said gears are'secured to shafts 39, and bevelgears 40 secured to said shafts'are meshed to bevelgears 41, which are secured to'the shaft, 42. .Said shaft is journaled with bearings in the printing carrier. The length of the pins in said pinwheel must be a} I the length of the type-bed to allow move:

ment of said pins in the spiral gear 34 for the size of prints. required. The sprocket wheels 43 lsecured to the shaft 42 are operatively connected with sprocket chains 44 to sprocketwheels 43 which are secured to shafts 42*, which are journaled with duplex bearings in the front part of the printing carrier.

The inking rollers 45 are secured with brackets 46 to the sprocket chains in a man- I 'nershown in Fig. VI. Said inking rollers are hollow, to he slid over shafts .47 screws 48 to secure said inking roller to said shafts. A collar 49 has screws to secure said shaft to said collar. An open position of said collar is shown in Fig. VII. The ends of said collarare journaled with bearings to the brac, ets 46. All operative rollers in this mac ine must be secured in collars to be easily changed.

The pins 51 to secure said brackets to said sprocket chain-must extend on one or on both sides torun in a rail-support 52 as shown in Fig. III, to give to the inking rollers the correct pressure on the inktable and the'type as required.

The ink'is supplied to the'inktable 30 by an ink fountain roller 53 secured to shafts inking rollers of'rollers'71 and'72.

to an idle shaft which hangs in springs 73 54. An ink curtain 55 passes over two rollers, running constantly in one direction to supply the lnk from the fountain to a. ductorroller 56. Said ductor roller supplies the ink to the ink-table as shown in Fig. IX. The ductor-roller is secured to sleeves 57, which are slidable on the crank shafts 58,

the springs 59 on said crank shafts giving correct pressure to the ductor roller when running in -a plane over the inktable.

The motion to the fountain and to the ductor roller is given by bevelgears 60 which are secured to the shafts 42". Bevelgears 61 meshed to'said gears'are secured to shafts 62. Bevelgears 63 secured to said shafts are meshed to bevelgears 64, which are secured to the crank-shafts.

Bevelgears 65 are meshed to the gears 64 and are secured to shafts 66. Bevelgears 67 secured to said shafts are meshed to bevelgears 68 which are secured to thedriving shaft of the fountain roller 53.

The motion to the ink-curtain is given by suitable pulleys secured to one of the ink to hold any width of paper 18. Said paper 1s constantly drawn from the supply roll,

through the guideways 17 over the printing platform 16 by a feedlng device consisting Roller 72 is secured secured to the platform 1. Roller 71 can be easlly changed for a larger or smaller roller. If the size of prlnt is 10",inches long, the

circumference of said roller must, be 10 inches. Said roller is secured with a set.

screw to a shaft 74, and a bevelgear 75 secured to said shaft is meshed to a bevelgear 76, which is secured to a shaft 77. A bevelgear 78 secured to said shaft is meshed to a bevelgear 79, which is secured to the driving shaft 13 of the machine. feeding device consisting of.rollers 80 and 81 can be easily connected to the driving mechanism if required.

The ink-fountain, the ductor-roller, the

inktable and the inking-rollers are built in parts slidable over shafts; as shown in Fig. III. When printing in one color secure said parts together with screws 48 tothe shaft as shown in Fig. VI.

When printing in difi'erentcolors, place washers 83 between said parts, and regu- A second F To regulate the machine for smaller sizes of will be seen that the type-bed remains parallel to a given plane throughoutthe printing.

prints in different color printing, it is necessary ,to use suitable smaller parts as shown in dotted lines in Fig III and the machine must be regulated for the size of those parts. The same size columns of type have to be inserted lengthwise in relation to the machine in the type-bed in a suitable'position to correspond with the inking rollers and vprint as usual.

The operation of the machine is as follows- Place a roll of paper of the size required in hanger 69, pass the paper through the gu1deways'17, place smoothly over the printing platform 16, between the. rollers 71 and 7 2, and regulate the eccentric 6 for the size of print required.

Next, I show the cooperation of the several parts throughout a complete circle of movements involved in the printing. It

operation, and the range of its movements in the direction of this plane and at right angles thereto may be regulated as desired. When the power is. applied the printing carrier is in the position shown in Fig. I, showing the inking roller going to' ink the type, and the ductor roller going to give ink to the ink-table, is moved by the eccentric '6 forward to the right and the printing carrier is moved upward by the eccentric 21. The inking roller running over the type and the ductor-roller gives ink to the inktable. The main carrier moves to its forward limit of movements and the printing carrier moves downwaf' dly to press the type against the constantly running paper lying on the top of the printing platform, while the inking rollers run over the inktable and the ductor roller up to the ink curtain. Then the carrier re-.

turns to the position shown Fig. I to be ready for the next operation.

I am aware that prior to my invention type printin machines have been made which printe in two or more colors with rollers on constantly running webs or sheets, I therefore do not claim such machines but- What I do claim as my invention and desire to secure by Letters Patent is- 1.
