Application led May 8,

This invention relates to color presses, an object of the invention being to provide means whereby two or more colors are print- Heretofore it' has been necessary in color presses to`run the paper through thepress for each color whereas with my improved apparatus I print both colors simultaneously, thus resulting in a great saving of time and labor and also givingabsolutely perfect results in the registry of the different colors.

My invention also includes improved means .for inking the type beds for a transfer of a plurality of colorsto the .proper type beds, improved ink distribution, and other details -of construction, all of Vwhich will more fully hereinafter appear in the specification and set forth in the claims.

With these andother objects in view, the invention consists in certain novel features of construction and combinations and arrangements of parts, which will be more fully hereinafter described and pointed out in the claims.

tical; section at one end of one of the inking t rolls and its adjacent parts, the view being taken on the line' 14-14 of Figure 1'2.

1 represents the frame of my improved printing press which supports a drive shaft 2, on which latter a sprocket wheel 3 isvfixed. 60 An endless chain 4 connects the sprocket wheel 3 with a sprocket Wheel 5 on a shaft 6. One run of the sprocket chain 4 engages and transmits motion to a vsprocket wheel 7 on a shaft'S, as clearly shown in Figure 1. 65 9 represents a strip of paper which is fed from a. suitable supply roll 10 through a guide and tensioning device 11, said 4paper having an intermittent positive movement which is caused by a pair of rolls 12 Vand 13. 70 The roll 13 constitutes the driving roll, on the trunnion vof which a gear wheel `14 is mounted and meshes with a rack 16. This gear wheel has a ratchet connection with the trunnion of the roll 13 so that it impartsmo- 75 tion in one direction only.

The rack 16 is movable in a guide 17 and is connected by a link 18 with a crank arm 19 ffixed to shaft 6. This arm 19 has a longitudinal slot 20 therein, and a connectin 30 bolt 21 projects through the link 18 an through the 4slot 20'and is secured by aset nut 22 so as to regulate the stroke or movement of the rack and the corresponding feed of the paper at each complete revolution of 86 the shaft 6. d

Atransverse cutter-23-is provided lat the end of the frame 1 to sever the paper transversely, and disk cutters 24 mounted on shafts 25 and .26, respectively, are adapted to 90 sever the paper strip longitudinally so that by the operation of lthese cutters cards or sheets of the desired size can `be automatically cut.

The transverse cutter 23 is provided with 05 one ormore depending rods 26 with springs holding the cutter inA elevated position. he lower ends of the rods 26 are connectedby links 28 vwith a fixed part of the frame 1, and acontrollingmember 30 10D hasl a cam face 3l adapted to engage a cross member 33 which' connects-the links 28 and I rods 26 so as to cause a downward movement of the cutter, as willbe readily understood.

This operating member 30 is connected by .1 alink 34 with a crank arm 35 on shaft 2, so that as the said shaft 2 revolves a re` ciprocating motion will be impartedA to the member 30. This member 30 has a suitable 'but in the same horizontal plane, and while I have shown and shall describe two of these type beds it is obvious that I may employ any desired number.

In the employment of the term type bed I use it in its broadest sense to include any form which may print or impress a color either in type or other character or form upon the paper sheet 9.

43 represents a carriage which is secured to an upright 44 on operating member 30 and caused to reciprocate therewith. This car- `riage 43 supports the desired number of inking rolls. I have shown four inking rolls, one pair of inking rolls 44 adapted to ink the bed 41 and another pair of inking rolls 45 adapted to ink the bed 42.

These pairs of inking rolls 44 and 45 are supplied by ink of the desired color from fonts 46 and 47, respectively, which 'are shown in detail in Figures 4, 5 and 6, and will now be more specifically set forth.

The fonts 46 and 47 are located at the upper portion of a frame 48 and have discharge rolls 49 which are engaged by rolls 50 connected by links 51. These rolls 50 also are adapted to engage supply rolls 52 and transfer ink from the rolls 49 to said rolls 52.

Y The rolls 5() are `moved ,laterally when the link 51 is reciprocated by the movement of the rocker arms 57, as will be hereinafter explained,l and during suchmovement will take ink from the rolls 49 and deposit it on the rolls 52, the two positions of these rolls 50 being illustrated in Figures 3 and 5, respectively. Rotary motion is applied to the rolls 52 through the medium of a sprocket chain 53 which connects the sprocket wheel 7, above referred to, with a sprocket wheel 54 on the trunnion of one of the rolls 52. The trunnions ofv these rolls 52 are connected by a gear train 55 so that they are compelled to turn simultaneously in the same direction.

The links 51 above referred to are pivotally connected as shown at 56 to the rocker arms 57, the latter pivotally connected aft their lower ends to the frame 48 as shown at 58. The upperends of these rocker arms 57 are connected to links 59, and ore of the links 59 is connected to the upper end of a lever 60, the latter pivotally supported between its ends on the frame 48 as shown at 1.

A coil spring 62 connects the lever 60 with thr lframe 48 and tends to move the lever in one direction, while a cam 63 on shaft 6 positively moves the lever` in the opposite direction. A pair of rocker arms 65 is connected to the link 59 and pivotally mounted upon the trunnions of the' font rolls 49. These arms 65 carry pawls 66 which engage ratchet wheels 67 fixed to turn with the font rolls 49 so as to impart a partial lturning movement to said rolls at each movement of the lever 60.

At one side of the frame 48 a horizontal cross bar 68 is located and has forked ends 69 engaging grooved enlargements 70 on the ends of parallel rods 80. This construction is illustrated more clearly in Figures 6 and 10. The rods are also mounted in suitable adjustable blocks 81 movable in the frame 48 and having set screws 82 to adjust the blocks. l

The rods 8O carry distributing rolls 83 which engage the rolls 52, and rotary motion is imparted to these distributing rolls by their contact with the inking rolls. To impart a. reciprocating movement to said distributing rolls 83 I provide cams 84 on the trunnions 85 of the rolls 52. These cams 84 engage rollers 86 on the bar 68, tending to move the bar in one direction, and a coil spring 87 located around a post 88 iixed to the frame 48 tends to move said bar 68 in the opposite direction. Hence. as the inking rolls 52 are revolved the distributing rolls 83 are caused to revolve and to reciprocate and smear the ink smoothly over the rolls 52.

To return to the inking rolls 44 and 45 and their operating and controlling mechanism, attention is particularly called to Figures 3, 7, 8, 9, 11, 12, 13 and 14. Each of these inking rolls is mounted alike at both ends, and in Figure 14 I show how one end of one of these rolls is mounted, it being understood that this applies to both ends and all ofthe rolls 44 and 45.

Each of. these rolls has trunnions 89 at both ends and each trunnion is mounted in.a sliding block 90 movable in a vertical slot 91 in the carrier 43. Each block 90 has a roller 92 mounted thereon and a coil spring 93 in the upper portion of the carrier 43exerts downward pressure on the block 90, tending to move the roll downwardly.

All of the rolls 44 and 45 therefore have f supporting rollers 92 at both ends and these supporting rollers are adapted to engage cams whichelevate the rollers at the proper time and during the proper length of time 44 ride up the cam 93 so that said rolls are presented to contact with the rolls 52 and so that Athe rolls 45 always take ink from the rightshand roll 52 while the rolls 44 always take ink from the left-hand roll 52 in F igure 5.

It is to be assumed, of course, that the ink on the two rolls 52 are of ditlerent colors. The rolls 45 can never contact with the lefthand rolls 52 as they move downwardly oil the cams 94 in their movement to the left of Figure 5.

As these rollers 44 and 45 move under the head 37, cams 95 and 96, respectively, cause the rolls to engage with their proper type beds 41 and 42. In other words, the cams 95 elevate the rolls 44 so that they engage the type bed 41 while the cams 96 elevate the rolls 45 so that they engage the type bed 42.

It will thus be seenthat ink of one color is applied to the type bed 41 and ink of an other color to the type bed 42, and that the rollers 44 never engage the type bed 42 and the rollers 45 never engage thc type bed 41 because of the location and arrangementof the cams 95 and 96.

The operation in general is as follows:

With the parts shown in the position illustrated in Figures 1, 2 and 3 the operating member 30 is in an extreme position. As the shaft 2 revolves this member 30 is moved to the right of Figure 3 and carries the rollers 45 and- 44 under the head 37. The cams- 93 and 94 elevate the rollers 45 into engagement with the type bed 42, and the cams 95 and 96 elevate the rollers 44 into contact with the type bed 41. As these rollers move up their respective type beds they drop down off their elevating cams and con-` tinue to move to the right until they are elevated by the respective cams 93 and 94 into contact with the ink supply rolls 52 and take a new supply of ink for their return movement. During this movement to the right of Figure 3 the member 30by reason of its cam face 3l causes the type' head 37 to descend and bring the type beds into engagement with the strip of paper 9. In the movement to the left of Figure 3 the head 37 is again elevated and the paper is causedto move a proper distance by the rack 16 and pinion 14, as above explained. During the-longitudinal movement of the paper the cutters 24 sever the same longitudinally and at each reciprocation of the member 30 the cutterl 23 is operated to' sever the paper strip 9 transversely. f

It will thus be noted that with my improved apparatusv I apply to the upper strip two colors simultaneously, the second color being applied to the same s ace or spaces upon the next operation o the printing head, so that the plurality of colors are always in register and the work is done continuously, dispensing with the necessity or running the paper twice through the press, such as is the common practice. Various slight changes and `alterations might be made in the general form' of the parts described without departing from my invention, and hence I do not limit myselfv to the precise details set forth but consider myself at liberty to make such slight changes and alterations as fairly fall within the spirit and scope of the appended claims.

I claim:

1. A color press', including a platen, a vertically movable head, a plurality of type beds located in the same horizontal plane at the lower portion of the head, a plurality of ink'ing fonts containing inks of different colors, a plurality of inking rolls movable horizont-ally and longitudinally of the press from the fonts to the type beds, cams causing the elevation of certain of said last mentioned rolls into contact with certain of the fonts, and other means causing the eleva' tion ot certain of said rolls into contact with certain of the type beds whereby ink of one color is imparted to one type bed and ink of another color to the other type bed. 2.
