FEEDING ATTACHMENT FOR PRlNTlNG-PRESSES.

SPECIFICATION forming part of Letters Patent No. 229,998, dated July 13, 1880,

Application filed February 13,1880.

To all whom it may concern:

Be it known that I, FREDERICK L. Goss, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in- Feeding Cards and Sheets into Printing-Presses, and in mechanism there for, of which the following, in connection with the accompanying drawings, is a specification.

In the drawings, Figure 1, Sheet 1, is a top viewof those parts of a printing-press in connection with which my improvements may be operated, or to which they maybe applied, and showing them in position for work. Fig. 2, Sheet 1, is a like representation of the bed plate, showing the mode of locking the form. Fig. 3, Sheet 2, is a section in the plane of the line now of Fig. 1. Fig. 4, Sheet 2, is a side view of one of the elongated nippers. Fig. 5, Sheet 2, is a top view of the said nippers.

Fig. 6, Sheet'2, is a like view of one of the guides. Fig. 7, Sheet 2, is a side view of the same. Fig. 8, Sheet 2, is a face view of the printed card or sheet, and Fig. 9, Sheet 3, is a detail of the means employed for raising or tilting the feed-board.

Like letters of reference indicate like parts.

The object of my invention is to provide means for printing illuminated matter in such manner that the stripes or bars of color shall extend diagonally across the card or sheet printed upon; and to that end my invention consists in feeding the cards or sheets in a novel manner, and in arranging the form cor respondingly.

It also consists in certain novel features of construction relating to the feed mechanism, all of which will be hereinafter fully described and specifically set forth.

A represents a rotary impression-cylinder, and B is a reciprocating bed-plate. O is the feed-board. D is the ink-fountain, and E E are rollers for feeding and distributing the ink. F F are the nippers. G G are the guides. H H are the rocking or vibrating fingers, and I I are fingers or yielding pressers applied to the feed-board.

As my invention consists in part in feeding the cards or sheets diagonally with relation to the cylinder A, as indicated in Fig. 1, wherein A represents the card or sheet so arranged, another feature of my invention consists in certain modifications of construction and arrangement relating to the nippers and guides forming a part of the feeding mechanism, and these modifications I will now proceed to describe in detail.

As the sheet or card is to be arranged diagonally, I make each succeeding nipper longer than the one preceding it, so that the I receding edge of the sheet or card shall be 6o reach ed and properly nipped by them, as shown at a a, it being understood that the number of nippers be sufficient for this purpose, and that in other respects they may be constructed and I may operate in the usual manner. If it be deemed desirable to nip more than one edge of the sheet, a nipper may be extended to seize the end of the sheet, as shown at a. The nippers, being removable and adjustable, may be adapted and arranged for sheets set at various 7o angles.

To adapt the guides to operate in connection with diagonally-arranged sheets I apply the working-faces of the guides adj ustably to their stems or stocks. In other words, I make these parts separately, and connect them in such manner that the working-faces may be set and inclined to correspond to the inclined or receding edge of the sheet or card. For example, I) I) represent the working-faces of 8c the guides, and b b are arms extending rectangularly or horizontally from the upper edges of the faces I) b. c 0 are longitudinal slots in the arms I) b, and d dare set-screws by means of which the arms I) b are clamped adjustably to their stems or stocks 6 e, the said screws passing through the slots 0 c and entering the stocks 6 0. By this means the working-faces of the guides may be set at an angle corresponding to the inclination of the receding or inclined edge of the sheet or card, and they may also be set out a greater or less distance to meet that edge, as indicated in Fig. 1.

J J are yielding pressers or holders, which may be either rigidly connected to the arms 5 b b, or this connection may be such as to render them adjustable with relation thereto, and p in the latter case this adjustability may be effected in like manner as the adjustability of the arms I) b is rendered possible, or in any similar or suitable way.

It will be perceived from the foregoing description and from reference to the drawings that sheets or cards A A may thus be arranged with uniformity in diagonal positions with relation to the cylinder A, and that they will be there held with sufficient security, and then seized by the nippers, and by them so carried around by the rotation of the cylinder and impressed upon the form, it being understood that the guides are vibrated or carried away from the edges of the sheets or cards, and returned at the proper times, as heretofore, or in any suitable way.

A small pin or stop, f, may be removably applied to the feed-board to aid in properly arranging the sheets or cards.

K is the form. As the sheets or cards are arranged and fed diagonally in the manner described, I arrange the form diagonally to receive it, as is clearly shown in Fig. 2, the inclination of the form being opposite or contrary to the inclination of the sheets or cards as they lie upon the feed-board, but corresponding to the position of the sheets orcards as they are carried around for beingimpressed upon the form,

The form as it passes underneath and in contactwith the lower inking-roller receives therefrom strips or bars of colored or illuminating inks, which strips or bars will pass diagonally across theform, owing to the diagonal arrangement of the latter. Consequently, the sheets or cards, being correspondingly arranged, will receive coloredimpressions, which will extend diagonally across them, while the letters or characters to be printed, if set in lines parallel to the ends of the form, will be printed straight across the sheets or cards, it being understood that inks of different color are placed in the fountain.

To facilitate the operation of setting the form diagonally I make in theinterior blocks, LL, which hold the form in its .place, deep angular notches g g, to receive the corners of the form, and the said blocks may be made tight by means of wedge-blocks in the usual manner, as represented.

As some of the nippers F F, which I employ for the purposes set forth, may in some cases be unusually long, and long enough to interfere with the sheets or cards, I have made provision for preventing such interference, and

to that end I make the feed-board tilting, and attach to it, upon its under side and near its forward end, a cam or inclined or beveled projection, h, and upon the cylinder A, 1 apply a thimble, h, arranged to strike the cam h and raise the forward end of the board intermittingly during the rotation of the cylinder, and at such times as to prevent an improperinterference of the elongated nippers with the sheet or card' upon the board. a

It will also be perceived that the sheet or card is thus impressed in one operation in such manner that the strips or bars of color or shading will extend diagonally across the card or sheet printed upon, as is clearly indicated in Fig. 8, wherein the shade-lines represent the diagonally-arranged illuminating colors.

By setting the type diagonally in the chase and arranging the form in the manner described the letters will also be diagonally printed. The like arrangement of printed letters will follow if the characters be engraved diagonally on the block and the block set diagonally.

Having thus described my invention, what Iclaim as new, and desire to secure by Letters Patent, is-- 1. The method, substantially as hereinbefore described, of printing or shadingilluminated cards or sheets diagonally, to wit: by feeding the cards or sheets diagonally into the press, and by arranging the form .in a correspondingly diagonal position, substantially as specified.

2. The combination, with the feed-board and impression-cylinder of a printing-press, of the nippers F F, each successively longer than the others, and having their working endsin aline extending diagonally across the cylinder, and of the extensible and vibratory guides G G, whereby sheets or cards fed diagonally into the press will be seized and gaged, substantially as and for the purposes specified.

3. The combination of the tilting feed-board O, the cam h, the thimble h, the cylinder A, and the nippers F F, substantially as and for the purposes specified.

FREDERICK L. GOSS.
