11 Claims.

This invention relates to improvements in multiple printing plates and actuating means thereother things, to provide means whereby work may be printed in a plu- 'rality of colors in a single operation. 6

' Another'object of" the invention is to provide a multiple printing plate consisting of a plurality of separate cuts, and actuating means for moving all thecutswhich print in onecolor to contact one set of inking rolls, and allthe cuts which print nanother color to contact another set of inking rolls, and to return all the cuts into-aligm ment prior to each printing operation.

A further object of the invention is to provide 15 a multiple printing plate and actuating means therefor wherein the cuts to print in each. color are mounted on movable carriers, andwherein means'are provided for moving the carriers to bring-each set of cuts intocontact with their 2 v proper inkinglrolls, and to provide rests by which all th'e'"cuts'are supported in alignment during each printing operation.

Yet'another object of the invention is to provide a "multiple printing plate and actuating 35 means therefor including a cam shaft having one-'setbf cams to actuate each set of'cuts, whereby each set is moved in sequence into position to contact the proper set of" inking rolls.

Having thus briefly stated some of the-major objects andadvantages of the invention I will now proceed to describe one embodiment thereof with the aid of the accompanying drawings, in

which Figure lillustrates a side elevation of a single.

35 form of machine equipped with my invention; Figure 2 is a plan view thereof, and Figure 3 is a partial sideelevation;

' Figure 4 is an enlarged plan view showing the multiple printing plate in position,

40 Figure 5 is a section on the line 5-5 of Figure 4, and

In Figures 1, 2 and 3 a single type of machine 46 is shown to which my invention is applied, though it is of course understood that my multipleprinting plate and its out actuating mechanism may be arranged to operate on various types of machines.

50 Referring now to the machine herein illustrated, I designates a base having a fixed table 2 thereon, and a vertical drive shaft 3 which may be driven in any preferred manner as through a pulley 4 shown fixed thereon. Secured upon the upper 55 extremity of the drive shaft 3 for rotation there- Figure6 is a section on the line 66 of Fig- 3 with is a spider 5 having

radial arms

6, 1 and 8. Upon each of the arms- 6 and I a conventional set of inking rolls 9 is provided, and the arm 8 carries a suitable work support II]. In the instance shown the work consists of a cylindrical 5- vessel A closed at one extremity and open at the other. The arm 8 terminates in a yoke II which carries a disc 82 to bear against the open end of the vessel A, and an inwardly extending member [2a upon the disc E2 to seat within the open end- 1' of the said vessel. Axially movable inv the arm 8 and projecting therefrom is a spindle i4 terminating in a pad l5 at its outerextremity to bear against the closed end of the vessel A. A

spring l6 around'the spindle I 4 and extending between the arm 8 and the pad l5 urges the pad to its work engaging position. denotes a fin-' ger which is pivoted upon the arm 8 and passes through a slot therein to engage a recess Ma formed in the spindle and move the latter axially I inward against the tension of the spring It to release the, work.

Supported beneath the table 2 in suitable bear ings I8 is a camshaft l9 having a gear 20 thereon which meshes with a gear 2! fixed upon the drive 5.

shaft 3. The gears are so proportioned that one rotation ofthe drive shaft eauses'one rotation of the camshaft. Upon the latter are two

earns

22 or 23 to actuate each set of

cuts

24 or 25 respectively in the printing plate 26. instance, for the sake of simplicity, only two sets of cuts are shown so that in this case printing in only two colors is contemplated. Obviously when printing is to be done in more than two colors additional sets of cams must additional sets of inking rolls are needed, one for each set of cuts. It will also be noted that all the cuts 24 which printin one color are so formed that they coa'ct with, and are movable independently of, the cuts 25 which print in a second 40 color.

Riding upon one pair of cams 22 are elements 21 which project from opposite sides of a carrier plate 28 having-a plurality of integral carrier arms 29 uponwhich allthe cuts 24 intended to print in one color are supported. The carrier arms 29 are slidable through openings formed in the printing plate 26 and through bosses or rests 30 formed thereon which constitute stops upon which the cuts 24 normally bear. Similarly rid- 7 ing upon the second pair of cams 23 are other ele- In the present 30 be provided and 34 thereon. Since the

carrier plates

28 and 32 are positioned one above the other the upper carrier plate 32 has clearance apertures 35 formed therethrough for the passage of the arms 29. The printing plate 26 is secured as by screws 36 upon the table 2, which is suitably apertured at 2a for the passage of the carrier arms 29 and 33.

Upon each revolution of the camshaft l9, first the cuts 24 supported upon the arms 23 are raised, as shown in Figure 5, by the earns 22 just prior to the passage of the set of inking rolls thereover by which the said cuts are to be inked. Continued rotation of the camshaft then permits the carrier plate 28 and the cuts 24 to drop back into printing position, after which the cuts are raised by the cams 23 to contact the other inking rolls. The cuts 25 then drop back into alignment with the cuts 24 prior to the passage of the work A thereover.

While in the foregoing the preferred arrangement of the invention has been described and shown, it is understood that the construction is susceptible to such alterations and modifications as fall within the scope of the appended claims.

What I claim as my invention and desire to secure by Letters Patent is:

l. A printing plate comprising a fixed member, a plurality of cuts intended to print in different colors normally resting against said member, the cuts intended to print in one color being separated from one another by cuts intended to print in another color, carriers, means extending from the carriers to the cuts, and means actuating said carriers in sequence whereby said cuts are moved in sequence to contact their different inking means.

2. A printing plate comprising a fixed member, a plurality of coacting cuts intended to contact difierent inking means and print in different colors normally resting against said member, all the cuts being movable in a common plane, carriers, means extending from said carriers to said cuts, and means actuating said carriers in sequence whereby said cuts are moved in sequence to contact their different inking means.

3. A print plate comprising a fixed member having apertures therethrough, a plurality of cooperating cuts intended to contact different inking means and print in different colors, all

-- said cuts being movable and normally resting against said member, a plurality of movable carriers, arms extending from said carriers to the rear faces of said cuts, said arms intermediately of their length being slidable through said apertures, and means moving said carriers in sequence whereby said cuts are moved in sequence to contact their different inking means.

4.
