PRINTING-PRESS.

SPECIFICATION forming part of Letters Patent No. 706,709, dated August 12, 1902. Application filed February 13, 1902. semi No. 93,8 4.. (No model.)

To obi/Z whom, it may concern; Be it known that l, HERBERT B. ALLEN, a citizen of the United States, residing in the city and county of San Francisco Sta'te of 5 California, have invented an Improvement in Printing-Presses; and I hereby declare the following to be a full, clear, and exact de scription of the same. I My invention relates to improvements in to printing-presses; and it consists, in combination with what is known as a quadruple perfecting-press, of mechanism whereby a web of paper not exceeding half the width of the press is takenfrom the rolls and passed through one side of the press and over the printing-rollers therein, is returned over to the starting-point and again passed through and over the printing-rollers within the other half of the press for the purpose of applying a second color or impression, and is thence transmitted to the second portion of the press and in like manner carriedthroughand over printing-rollers by which a third color or inn;

pression is applied to the sheet before it passes to the folders and eventually leaves the ap-' paratus.

My invention also comprises details of con-*- struction, which will be more fullyexplained: by reference to the accompanying drawings,

in which- 7 Figure l is a perspectiveview showing my attachment.

the rear part of the press B. Fig.4 is a rear View of Fig. 8. p The object of my invention is to so construct the press attachments thatthe' paper taken from the roll may be passed over im- 40 pression-rolls bearing different colors, whereby the paper maybe imprintedwith a plu-' ating inking-roller 4.

Fig. 2 is a plan view showingthe general arrangementof the device. Fig. 3 1s a diagrammatic View showing'in general sides before being delivered from the press. In my invention I have combined with these structures devices which enable me to return the paper and pass it again over the printingirolls ,each added passage applying a new color I or tint.

The part A is provided with a holder or support 2for the web of paper, upon which the roll of paper3 ismounted andfrom which it is carried through the press and over the Type carrying or printing rollers, as at 4,

where one or more colors may be applied to the sheet. The printing-roller has a cooper- The rollor web 3 does not exceed half the full length of the rollcarrier, and after the paper has passed over the printing-rolls which are in the line of its travel it passes over direction-rollers, which take it up to a point above the top of the part A, and from the upper roller 5 it passes horizontally over a diagonally-placed lead roll or bar 6, which is suitably fixed in the line of travel ofthe paper and so as to change its direction to one at right angles. The Web passes in thisdirection a short distance to a second diagonally-placed lead-bar 7', which directs the web of paper back over the top of the press,as shown at 8. Thence it passes over a direction bar or roller 9, thence over a directionbar or roller 10, thence beneath the direction roller or bar 11, which again passes it through the press and over the color-surfaces of that side of the press and parallel with the web as it first enters the press. These 8 5 second passage through this part of the press.

In order to provide for this return of the paper, 0 I ,haveshown standards 12 fixed upon the main frame ofthe press and carrying brackets 13, in which the ends of the guide bar or roller 9 are supported at a sufficient distance away from the press to cause the paper to 5 travel clear of it on its return movement to the lower portion. The guide bar or roller 10 in like manner is carried in brackets 14, which are fixed to and projecting from the frame A of the press, and the paper is: thus Ioo brought to a point where it can be again passed into the press over the guide-roller 11.

After having passed the second time through the press the paper is again carried up to a point above the top of the portion B of the apparatus by suitable guide-rollers and is carried across the open space between the parts A and B, passing over the lead-bar 7 and thence over a lead-bar 15, which is fixed diagonally across the upper part of B. From this lead-bar the paper passes to the back of the part B, thence over a guide, as at 16, which directs it downwardly, thence over suitable guides, which direct it into the press B, where it passes over other printing-rollers in the line of its travel, whereby a third color may be applied in addition to those that have already been received in the part A.

This device is especially designed for use upon newspapers which have supplemental sheets printed and upon which it is desirable to print in a number of colors. The portion passed through the press, as just described, provides for this color-printing and enables the operator to apply at least three colors.

The portion of the paper which is to be printed in black may be taken from a roll carried upon a guide or roller over which the sheet heretofore described passes from the direction-roller 16 and at the opposite end of the roller, so that it passes through the press simultaneously and parallel with the colored portion in its final passage through the part B. In Fig. 3 I have outlined the rear portion of the press B to show the direction of the roll of paper after it leaves the direction-bar 16 and passes down over the rear of the press. Thence the paper passes over a roller a, thence over another roller 7), and thence over a series of rollers at c. The roll of paper at (1 passes up over direction-rollers e, thence over the printing-cylinder f, thence over a diagonal direction-bar g, and from this bar the paper comes parallel with the other sheet, as shown scarce at h, and the two sheets go into the cutting and folding apparatus (not shown) and are folded together and delivered from the press in any Well-known manner.

Having thus described my invention, What I claim, and desire to secure by Letters Patcut, is

1. The combination in a printing-press of the independent presses A and B, a feed-roll from which a continuous sheet is first delivered through one-half of the portion A, diagonally-disposed guides located between A and B over which the paper is passed and by which it is returned over the top of A, direction-rolls whereby the continuous web or sheet is returned parallel with the first portion and again passed through the press, other direction-rollers by which it is carried from the part A over the top of the part B, a diagonal lead-bar over which it passes and by which it is directed over the top of the part B, direction-rollers by which the sheet is transmitted downwardly and into the press B to pass over printingrollers within said portion.

2. The combination with a two-part press A and B, of diagonally-disposed lead-bars, means by which they are supported between the parts A and B, said bars serving to return a continuous sheet of paper over the top and again into the part A after it has once passed through said part,directi0n-rollers and a lead-bar located above the part B whereby the continuous sheet finally delivered from A is caused to pass through the portion B to receive a third impression.

In witness whereof I have hereunto set my hand.

HERBERT B. ALLEN.
