To all whom t Amay concern.'

Be it known that I, MAX KRAvITz, a sub ject of the Czar of Russia, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented new and useful Improvements in Multicolor- Printing Presses, of which the following is a specification.

l This invention relates to improvements in multicolor printing presses designed particularly for printing two or more `colors in a single operation, the primary object of the invention being to provide a simple, eili cient and comparatively inexpensive construction of press of this character which shall be reliable in action, and adapted to effect the inking of the form matter and -the timed operation of the elements in proper accord to impression.4 ,y

A further object of the invention is 'to provide a.construction wherein the subject matterfto be printed is arranged in a plurality of type forms, disposed one in rear of the other, and which are, simultaneously print an absolutely clear 'inked-by. sets of inking devices, and in which the action of the press is' such that.

zation of parts, including novel forms of type and spacing devices, and a novel c onstruction and arrangement of form carriers and inking devices, whereby any form matter may be easily and conveniently set up and clean-cut impressions in two or more colors 'obtained in a single operation, with out the objections presentin that type of multicolor presses wherein the type'matter isarranged in a single form vandthe sets of inking rollers are thrown into and o'ut of inking position with relation to linesl of tyoe on their course of inking motion,

A still further objoet of the ipventlon is to provide a construction by means of which env Dortion'or portions of a body of matter form fully open or spread. Fig. 2 isa to be printed may be printed in a color distinct'from the rest, without the necessity 'of lim'itlng the printing actionin distinct c01- ors to different blocks or .lines o'f t e, whereby objections incident to prior-mu ticolor printing machines are eii'ectually overf come.

With these and other objects in view, thef invention. consists of the features of construction, combination and arrangement of parts herein fully describedand claimed,

reference `being had to the accompanying drawings in which lgure 1 isla side elevation ofa'printing press embodying my invention, showing the ont elevation of the ress. Fig. 3 isa vertical:

Re erring 'to vthe drawings, 1 designates the frame of the press on which is'journaled part of the la horizontal transverse drive shaft 2 which may be operated by any suitable power, a foot power mechanism being shown in the present instance consisting of a treadle lever 3 and a connecting rod 4: coupling the same to a crank onthe shaft. The shaft 2 car-' ries at one-end a fly wheel 6 and at its oppo site end a gear pinion .7 which latter meshesy with a gearS on one end of a horizontal transverse countershaft 9, which is provided at its opposite end with a crank disk 10.

The gear 8 is provided with a cam groove nimes? Y the carriers will be, brought exactly into registering position. As stated, the rocker .arms 29 swing loosely upon. the shaft 30, and for the purpose o communicating roc ing motion thereto 'inV the back and for h motions of the ,carriers connecting rods'60 rear ends with crank arms 62 secured to flugs 63 projecting from the rocker arms, so that in the rearward movement of. the carriers an upward pull will be exerted on the rocker arms to swing them upwardly and rearwardly, and thereby cause the rollers to move over the printing plates to take up a supply of ink, while on the forward movement of the form carriers the inking rollers will move forwardly and downwardly 'and ink the forms prior to the time they come into printing position.- Gripping ingers are provided toA clamp the sheet against the platen and withdraw the printed sheet from contact with the forms. These fingers are operatively connected with the platen 4and frame in any suitable manner.

In thepractical carrying of my invention into eli'ect, part of the matter to be printed in one color is disposed upon the form 25 while the remainder of the matter to be` printed in -a'diderent color is disposed upon the form 27', and the construction of the type employed is such as to permit the type matter composing the :rear form to moveA through the front form. to bring the sets of type matter upon the dierent forms into alinement for the printing action in which both Colors are printed simultaneously. The

type 65 upon the rear type form maybe of any suitable, construction, while the type 66 upon the front type form is provided in its opposite sides with grooves 67 and in `conjunction therewith spacers 68 are used,

which are preferably threesided, so that in the setting up the type composing the matter to be printed by the front form the spacers may have their two parallel sides fitted into ooves 67 of adjacent type 66 so as to provide spacesor openings 69 for the passageand reception of the type 65 u'pon the reanorm. Thus it will' be understood that the type composingthe matter upon the rear form which is to be printed in 'any certain color will be inked byone set of inlring rollers with ink of that color, while the type composing the matter-upon the fr t form which is'to be printed in another collir will be vinked by a separate set of inking rollers with `inl; of thedifferent color, and when the type forms 'are brought together or closed from the space or open position' the twqforms will exactly the subjectmatter thereof in the di'erent vcolqrsupon the sheet resting on the platen.

0f course, it is to be understood that the ,typematter upon -the different forms may be so set up that any portion of a line, pararegister to prin-t A graph or body of matter may be printed-in one color while the remainder may be printed in a dierent color. By this means the objection to prlor presses of thischaracter, which admit only of-diierent lines or paragraphs belng printed in/separate colors,

sections or other subdivisions of lines or `is avoided in a simple and eiicient manner,

other portion of matter to be printed may be printed in a color contrasting with the color of the remainder of the matter.

shown 4for printing two colors, it will of while in, the present instance two forms only. are

course be understood that any number of vforms may be employed by uslng, in all except the rear form, type 66 and spacers 68 of the construction shown in Fig. rEl() in 'conjunctionwwith type '65 upon the rear form, th\` type being mayr require so that the faces thereof will register wheny the forms are brought into closed or printing position.
