I HERBERT miss SALMON AND JOHN caress. smears, ENGLAND.

I noranr r'nrnrnre-kacrmin- 'Be it known that we, finalise-r J suns San- Q non and JOHN Carramsubjects of the King of Great Britain and Ireland, residing at .Woodley Iron Works, near Stockport, in the county of -Chester,'England, have invented certain new and useful Im rovements in Rotary Printing-Machines, 0 which the following is a specification. I This vention relates to rotary machines for rinting upon oneside of sheets of paper or t like, and has for its object to produce such a machine capable of dealing with a larger fiantity of work with but one impression cy der than is at present possible with the usual flat typlebed machineem loyed for this 11 se'. eretofore it has een propose wlth this object in view, to feed simultaneously, two or more sheets of pa er to one impression cylinder provided wit two for more sets 05 grippers, and to employ late cylinders of the same diameter as, or 0 less 1 diameter'than, the impression cylinder for printing one or more tunes for each revolution of the latter.

Our invention comprises the improved combinations and arrangements of parts hereinafter described and claimed.

Referring to the two accompanying sheets of explanatory drawings -Figur e 1 is an elev'ation representing a printing machine having our invention applied thereto and capable of giv ng two impressions, which may be different in character, twice in each revolution ofthe impression cylinder. Fig. 2 similarly represents the application of our invention to a printing machme for giving two similar impressions', initwo colors, in each revolution of the impression cylinder. Fig. 3 illustrates a further application of the invention, the printing machinein this case being capable of giving two impressions, whichmay be different in character, in each revolution of the impression cylinder-r. Fig. 4 is a detail view to .e hereinafter'referred to.

The same reference letters in the different views indicate the same or similar arts.

1n the arrangement shown at 1g. 1, we

' arrange feed boards a, b respectivelyat the up er and lower. sides of the impression pecification 61 Letters iatent,

are disposed atz'equal intervals-aro the circu erence of the impressioon cylinder 0, as shown, two of said grippers as at dandf,

cylinder 0, being arranged to take the sheets I) in the usual manner. The clips or grippers which are on opposite sides of'the impression from one feed board as a, and ,the' other two as at e and g to take them from the other feed board 6; The grippers are not shown in this figure but-they are lllustratedat d and f in Fig. 2; The type or plate cylinder'h is of half the diameter of the impressioneylinder c, so that it will print twice for each revolution of the impression cylinder. Thecylinder h, maycarry stereo, electro-type or other printing lates, or may support turtles carrying wood blocks, type or. linotype slugs; or it may carry zinc or other suitable metal plates" which will be used in combination with the damping and inking rollers usual for the class of work with WhlCll they deal. In the exam le illustrated, the cylinder h, may have two di 'erent forms on its circumferential surface, and in this case the alternate sections of the impression cylinder 0 will receive their impressions from oneform and the other sections from the other form. The sheets fed to the impression cylinder 0, fromthe feed board I) are delivered from the former beyond the upper feed board a (measured'in the direction of rotation of the impression cylinder), the usual switches or board m. Said bands is may comprise, as.

shown in- Fig. 4, a number of chains carrying bars ask, k, the latter carrying fingers or cipcs' kf adapted to press a ainst the surface 0 l.

and so hold the end 0 a sheet of paper between them. The bars 7c"will be rotated by any ordinary mechanism as usually emp oyed for this pur ose.. It will be seen that when the type or p ate cylinder his arranged to give two impressions of different character for each of its revolutions, all the sheets with the same impression will be delivered to the same delivery board, for similar impressions,

as before described, will be given on alter- 5. p we may employ a roll feed with cuttin roll- Irate sections of the cylinder c, and only alter- .nate sheets are delivered to the same delivery board. The cylinder b has the usual inking and distributing rollers.,-receiving their ink from the duct 12. by the vibratory roller as shown.. The. inking rollers are preferably impressioncylinder-c is fitted with only twosets of grippers d, f, one as d receiving sheets from thefeed board a, and the other f, receiving sheets from the feed board I). a Two type or plate cylinders h are employed for printing in two colors in the well known manner, each cylinder receiving ink from a vduct 12. through the usual-vibratory, distributing and inking rollers, as shown. The

cylinders h are of half the diameter of the impression cylinder and therefore give an impression twice in each revolution of the, latter cylinder. The carriages car ing the inking rollers can be moved relative y to the cylinders h by means of the-screw and nut device illustrated. -We may if desired dispensewith one of the cylinders h in this machine when printing in one color only. 7 The machine as illustrated in Fig. 3 has a type or plate'cylinder hof the same diameter as the impression cylinder 0. The cylinder h has two sets of type or plates which may be i different in character and the cylinder c hastwo impressionsurfaces. The delivery arrangements are the same as shown in Figs. 1 and 2i In the machines shown at Fi s. 1 and 3, we

quay if desired employ 'two cyIinders h with The sheets to be printed may be placed in the grippers on the impressioncylinder 0 by" ban or b automatic feeders of any usual and 'suita 1e construction. For example,

are for deliverrrrg sheets of a certain size at one feed board and an automatic sheet feeder at the other feed board. Or we may employ a roll feed and a hand feed, or an automatic sheet feed and a hand feed, or any other combinations of such feeding means.

If desired arrangements may be made for driving the inking apparatus when it is out carried loosely on the shaft of the cy inder hbut capable of bein driven from such shaft by a clutch or 11 e device when required. Said wheel or pulley 1' drives a band or chain r which rotates a pulley or spur wheel 1" capable of enga ing the spur 4 wheel 1' on the roller r when t e carriage h is moved away from the cylinder h. B

this means the inking and distributing rol ers and the printing cylinder 72; are driven in unison without making contact with one another and thus the ink is distributed on the rollers ready for engagement with the cylinder'h.

By the use of our invention we can with one impression cylinder more effectively accomplish a greater amount ofwork in a given time than is at present possible with flat type bed machines which are usually employed for se arate sheet printing.

aving now described our invention,

what we claim as new and desire to secure by Letters Patent is 7 1. In rotary sheet printin machines, the

combination consisting of a single impression cylinder, a )lurality of gri pers on said impression cylinder, means or feeding a pluralit of sheetsto said cylinder during each revo ution from two points respectively above and below the cylinder axis, separate delivery means alternatingand corresponding with said feeding means, a printing c linder, and inkin and distributing rollers or said printing cy der, substantially as described.

2. In rotary sheet printing machines, the combination consisting of a single impression cylinder, a plurality of gri pers on said impression cylinder, means or feeding a plurality of sheets to said cylinder during each revolution from two points respectively above and below the cylinder axis, separate delivery means alternating and corresponding with said feeding means, one of said delivery means turning the sheets while delivering same, a plurality of divisions on said printing cylinder corresponding with the divisions formed by the said grippers on said impression cylinder, substantially as described.
