Specification of Letters Patent.

Patented Aug. 3, 1909.

Application filed April 10, 1909. Serial No. 489,115.

To all whom "it may concern:

Be t known that 1, Henry D. lVnsnnunN, a sub ect oi the King oi Great Brltaln, re

siding at Salem, in the county of Essex and is conveyed from the ink-reservoir to the ink disk ot the press in an exceedingly even and thoroughly distributed condition.

The nature of the invention is fully described in detail below, and illustrated in the accompanying drawings, in which Figure 1 is a view in side elevation showing my improved ink-supplying apparatus applied to a printing-press of the type mentioned, a suiiicient portion of the press being shown to illustrate the operation of the invention. In this figure the attachment is shown with the distrihutingarolleii's having just received a supply of ink from the cylinder. Fig. 2 is an enlarged view in side elevation of the apparatus with the distributing-rollers down and depositing film of ink on the ink-disk. Fig. 3 is a similar view with the distributing-rollers fully raised and Fig.

Similar numerals of reference indicate corresponding parts.

Rc'terencc-anuncral 10 represents a portion of the main frame of a printing-press of the character referred to, and 11 represents a ln'ackct or frame which supports the circular ink-disk 12 in the ordinary manner, the mechanism 13 for rotating the ink-disk, and the mechanism 14 with which the form-roll- 15 are connected. The frame 11 has rigidly secured to it the bracket 16 to which at 17 is bolted a downward extension 18 rigid with and making a part Off a. horizontal jli'rame 1%) which supports the horizontal shaft which. has its hearings in the opposite end-portions 21 of said frame, said shaft supporting the ink-cylinder 22, said shaift 20 and ink-cylinder 22 being at right angles to the form-rollers 15, and said cylinder rotating in a plane which is at right angles with the plane of rotation of said :t'orm-rollers. This ink-cylinder extends down into the ink-reservoir 23 in the ordinary mani'ierin presses otthis character, said reservoir being parallel with the inkcylindem constructed as usual and provided with the ordinary flexible blade 24. and adjusting thumb-screws 25-the reservoir being sustained by the

frame

19, 21 as illustrated in Figs. l1 and 5.

26 represents the composition distributingrollers supported by a shaft 27 whose opposite ends are sustained in the

portions

28 and 29 of a vertically swinging frame 30, said frame being pivotally supported at 31 by the extension 18 From the reservoir-ireme 19 and the

frame

28, 29, 30 being provided with an integral cam 32 whose slot 33 is engaged by a canrroll S t extending horizontally :trom a cam-lever 1-35 whose upper end is pivotally COIHIUCLOd at 36 to an arm 37 eX- tending diagonally upward from and rigid with the extension 15% oi the frame 19. The cam-lever is pivotally connected at its lower end at 38 with the rod or link 39 whose lower end is connected at 4:0 to the formroller frame l1 of the press-the operation of which, as is well known, is to swing the fornrrollers 15 after they have been receiving ink from the ink disk 1.2, to the form of type. Another rod is pivotally connected at 40 to the form-roller frame 41 and its upper end is pivotally connected at 43 to an arm or lever 4tlrigid with a hub -il-5 which slips on the shaft 20. Rigid on this shaft 20 be ween the hub and the

trame

19, 21, is a ratchet-wheel 46 on which rests a pawl 4L7 pivotally secured at el-S to the ratchet-arn1 ell.

As is well known in printing-presses of this character, the :tornrroller :Erame il re- ClPIfOCtLlIQS on an arc of a circle whose center is at 49, Fig. 1., such movement of the formroller frame being for the purpose of carryting the itornrrollers 15 irom the ink-disk 12 to the form for the purpose Oil transferring the ink from the ink-disk to the type. My attachment is operated by means ol. the connection. ot the roos 39 and 4-2 at ll) to the :lForm-roller tralne i1. ll hen the parts are in the position illustrated in Figs. 1 and i, the ink-cylinder and the distrihuting-rollers 26 and their frames and shaft are parallel and horizontal and the distributingrollers have just taken ink from the cylinder,

and the form-rollers are taking ink from the ink-disk 12.

.the horizontal portion of the slot leadsv into the curved portion thereof, the

frame

28, 29,"

30 'is swung downward from the pivotal point 31 by reason of the dip of the slot carrying with it the distributing-rellers 26 until they reach the surface of the ink-disk 12, as shown in Fig. 2-the said distributingrollers therefore leaving a horizontal posi-.

tion in which their axes are at right, angles to the axes of the form-rollers l5 and reaching the ink-disk just after the form-rollers have. moved from under them, and lying on said ink-disk in a radial line, and still at right angles with the form-rollers. as the distributing-rollers reach the ink'disk theyare rotated by said ink-disk by means of the ordinary mechanism 13, said disk movingunder them, therelative movement of the distributing-rollers being ina circle around the center of the disk,and practically covering in their travel the entire disk between its center and circumference, and always being radial therewith. At the same time, that is, while the form-roller frame 41 a is swinging up, the rod 42, whoseupper end is pivotally connected at 13 to thearm 4:4: swings said arm upward, carrying with it the ratchet-pawl at which slips overthe ratchetwheel 46 from the position indicated in Figs. 1 aud t into that indicated in Fig 2.. When the form-roller frame 41 begins to. re-,

turn toward the position indicated in Fig. 1, the rod 39 is pulled down acting on the camlever'35 which by means of the cam-roll 3i inder 22 rearward, causing it to apply'ink to the distributing-rollers 26qas soon as they. By the time the form-- reach its surface. roller frame l1 reaches the lowest 'pomt'of its throw, as illustrated in Fig. 1, the dis-' tributing-rollers have been provided with ink and are ready to be carrieddown again 1 While the form-rollen frame was descending,*the fornrrollers -15 werebrought up in the usual manner liyiwell l to the ink-disk 12.

As soon only thereof as is the case when rollers or 2 cylinders of any kind are reciprocated over a portion only of an inkplate. distributing is rendered more even from the fact that the distributing-rollers themselves are turned or rolled by the disk.

Referring particularly to Figs. 4: and 6, it

tends forward from the portion 29 of the distributing-roller frame, and that a sprlng 5O surrounds the shaft between its headed outer end 56 and said portion 29. A sleeve or collar 5i integral with said portion 29 extends rearward therefrom around the shaft and is provided with fingers 52 which extend 'for a short distance overa sleeve or collar 53 integralwith the portion 18. Thls Moreover, the

will be noticed that the shaft or pivot 31 eX- sleeve 53 is provided with a peripherallug 54E. -When the device is being operated the spring 50 holds the distributing-roller frame by means of the cam 32, cam-roll 34,

cam-lever 35, and arm 37 into connection with the cylinder-frame By pulling outward the sleeve 51 the camroll is with-e drawn from the cam-slot,fand the distribut lug-roller frame may be swung up into the position indicated in Fig. 3, and locked in I with its fingers52 on opposite sides of the lug 5 1. To move the parts back into operative 13051t1011,l1l1 sleeve 51 and the d1St11l)-.

uting-roller frame are again pulled forward and swungdown until the cam-roll is in engagement with the cam-slot, and the parts in the position indicated inFigs. 4 and 6,

being held in such position by the spring 50 such position by moving the sleeve 51 back i which is partially compressed between the head '56 and the projecting portion 55 integral with. the portion 29. i p

The ink-reservoir (see Fig. is hinged at its lower: endby meansv of the pin 57 to e the cylinderframe, and may be swung down for cleaning purposes by turning the thumb-screws 58 which look the upwardly extending arms 59 to the cylinder-frame.

, Having thus fully described my inven-' 111011,, what I claim, and desire to secure by v Letters Patent, is 2- 1.111 an ink-supplying apparatus for PIHLUIIg-PIGSSGS of the character described,

an ink-disk, form-rollers for receiving ink from the ink-disk, a stationary ink-cylinder frame, a;distributing-roller frame pivotally supported by the cylinder-frame and adapted to swing in a verticalrplane, a cam ex tending from the distributing-roller frame, a {cam-lever pivotally connected with the cylinder-frame and provided with a camroll which is normally in engagement with the cam-lever and the operative portion of,

the printing-press whereby the distributing- .roller frame may be swung from the ink cylinder to the ink-disk in a plane which is at substantially right angles with the formrollers, for the purpose set forth.
