@Fffornejs JOHN A. WHITTINGTON, OF ATLANTA, GEORGIA.

PRINTING DEVICE.

To all lwhom it may concern:

Be it known that I', JOHN A. WHrr'rrNo- ToN, a citizen of the United States, residing at Atlanta, in the county of Fulton and State of Georgia, haveinvented certain new and useful Improvements in Printing Devices; and I do hereby declare the followin to be a full, clear, and exact description o the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to devices for printing in more than one color and the primary object of the invention is to provide a typel chase for multicolor printing which is simple in construction, effective in use and not liable to easy displacement of parts.

In such devices, means are provided for printing from different lines of type in different colors at a single operation, or with a single compression and for this reason it is necessary to so manipulate the different lines of type and the means for inking such lines, that different colors of ink will be placed on the different lines without interference with each other, and in carrying out the object of the invention I provide improved means for such purposes.

With the expressed general object of the invention in view, my invention consists in the improved construction, arrangement and combination of parts hereinafter fully described and afterward specifically claimed.

In order that the construction and operation thereof may be readily comprehended,

I have illustrated an'approved embodiment of my invention in the accompanying drawi ings and will now proceed to specilically describe the same in connection with said drawings 1n which-'- Figure 1v represents the device 1n plan v1ew y with the parts in printing position, l

Fig. 9, a longitudinal, sectional view on the vertical plane indicated by the dotted line 9-9 of Fig. 8, and

Fig. 10, a detail elevational end View showing the support for the ink tank in connection with the type plate.

Like reference characters indicate the same parts in all of the figures of the drawing.

Referring specifically' to the drawings 12 indicates the outer, box like structure, comprising two substantially U-shaped halves or end plates 13, 14, in which a tripper frame 15 is mounted which telescopically carries an inner frame 16, the tripper frame 15 be ing normally held above type level, or above the box 12, as seen in Figs. 5 and 8 and hereinafter explained.

The end U-shaped plates 13 and 14 of the box 12 are secured to the bottom by suitable means such as screws 17, as seen on Fig. 8, passing into upright fianges 18 of the bottom.

The frame 16 is recessed in its upper face, as at 19, Figs. 7 and 8, to receive an electroplate 20, a slide 21 in one side of the recess, backed by a spring 22, serving to permit of the ready removal of the plate, and springs 23 keeping the plate pressed outward to maintain it in upper position.

At each end of the machine are two levers 24 which have intermeshing teeth or cogs at their inner ends so that they 4must move simultaneously von their pivots 25. These levers are pivotally connected also to lthe frame 15 by pins 26l and by reason of these connections, the frame 15 will be compelled a frame or bar 34 in which is removably securable, by a screw 35, an electrotype 36 intended to receive ink of a dierent color from that of the electrotype 20.

This lever 27 is normally and yieldingly pressed upward by a spring 37 and carries in its upper surface afbumpe'r 38'which contacts with a block 39 carried by the frame l5 and normally pressed downward by springs 40.

A'cam piece 41v depends from the electroplate 20 (see Figs. 8, 9 and 10,) thefront edge 42 of which is inclined to'bear against a roller 43k carried .by an upright 44 secured to the support 45 of an ink tank 46, which tank hasits end supplied with perforations 4.7 to perm-it 4the, color ink carried in the tank to ooze through to a porous inking pad 48, by which the ink is taken in and supplied tothe electrotype 36 carried. by the frame or bar 34, such contact of the electrotype and the inkinv pad taking place When the electrotype 20, 1s depressed against the tension of the springs 23 by the inking rollers of the press, causing the inclined edge of the cam piece to move the ink tank and the inking pad against the electrotype 36 while in its inactive position as invFig. 8.

The ink tank has a suitable stopper and also has depressions 49 in its upper surface intov which project side flanges 50 whereby the tank can be raised andremoved by placing. the thumb and finger in thedepressions and clasping the flanges. 4rl `he electrotype QOis normally and yieldingly held` slightly above type level, and above the tank and pad, by. thesprings :23,and 'the ink tank,

and with it the ink pad, are normally and yieldingly upheld bysprings `51, and are thus automatically moved away from the type36 when pressure is removed.

In its lowerY or inking position, the type bar 34 rests on an elastic bumper 52 which serves to preventjar or shockwhen the bar is turnedy on the shaft 33.to its lower posi.- tion and said bar 34 is normally yieldingly held in its lower position by a spring 53 attached to and coiled about the shaft 33 and having its outer end pressing against the bar 34, as seen in Fig, 8.

The construction and arrangement of the parts of my ,invel'ltlonl will bereadily understood fromithe foregoing and the, op'- erationniay be summarised as follows: .In-,the use of the devlce and-after ithas been set up in the regular forni, the inking `rollers pass ,over it, and ink and slightly depress the electroplate 2O which in turn moves the inking pad 48 intoA engagement with and inks the typebar 36.V Immediately after the inking rollers have passed over the device, the various parts return to ltheir normal position.

Since the tension of the :springs 37 ment with the tripper frame andlsincethe power applied to the paper carrying plate is greater'tliantlie strength of the springs 37, the tripper frame `will.necessarily be depressed. -This depression ofthe tripper frame will actuate. thelevers 2,7 which in turn2 will through their connections lrock the, type bar 36 upwardly into. pri'ntyin'gu-position.

The type bar 34 'has an a'zle, 33tlirough 'i it and can be turned on this axle against the tension ofthe spring which 1s connected to that shaft and the bari` It will be, noticed.

that when the typebar 34- isstopped'in per.- pendicular position, thetripper frame 15,. has.

een forced down, but has not quite reached type, level. Itis therefore necessary for-the spring between the type bar 34 and' its agile to yield a little to allow this tripper frame to reach type level. The reason for having this double spring arrangement is for the type bar to stopl moving before the paper comes in contact withit. This is necessary,

for should the'paper come in contact with` the moving type the ink would be smeared on the paper instead ofV making a, clear in ipres'sion.

',100 l l have, shown an electrotype 36., l f may use special type with short stems in.

stead.- Such type may be' Set in. the slotv where the electrotype 36 is now held, and secured by a set screw or other means; .This will enable the printer to change thewording of the line (to beprinted inzoolor) at will.

l On a newspaper press the blank paper wrapped arounda steel cylinder and: the cylinder rolls over the fiat bed of type,I in which the device is inserted, and, approaches from any of the four sides. My machine,

with the tripper frame 15 @Xtcndng all around, Will Work on a4 pressof this kind' The machine will not only Operate'from: any

Side but the. freinefwll be. held, downuntl, the cylinder carrying the paper.y haspassed entirely over the machine, thereby. preyent" ing the typeline fromV moving while thel paper is inV contact with,l it.

I have specifically described thel construction, arrangement and combination of the parts vbut I do not confine myself to the same, but hold that slight changes or variations therefroinmay be made withoutavoiding the scope of,V the claims or edeparting.4 from the spirit ofthe inventlon.I

Having thus fully described my"inverttion, what I claim as new and desire to secure by Letters Patent of the United States, is:
