PRINTING PRESS.

Application filed December 27, 1921. Serial No. 524,896.

and more particularly to presses used in the printing of manifolding paper, or other ruled line, blank form paper, in which it is desir able that uniform position of printed matter on webs of paper be accurately maintained at all times. It also relates more particularly to printed form machines, which employ continuous webs of paper.

Referring more particularly to the printing of manifolding forms by which is meant a plural series of the same form adapted to be superimposed for the purpose of making carbon copies orother forms of transferred copies. In such printing the misalignment of printed matter on forms that are later to be placed together will result in an improper placing on the under sheets of the transferred marks made on the topmost or master 80 sheet.

The usual method of printing manifolding forms is to run a wide web of paper through a printing press, and to print crosswise of the sheet the desired number of forms, usually three. These. forms must correspond exactly, as has been stated, and this correspondence should be not only with relation to the longitudinal placing of the printed matter on the paper, but also to the lateral placing. The webs are later split up into three (in this instance) separate webs, and are fed or placed together in a manifolding machine, or pad, or the like, so that the close correspondence of the side edges of the forms or aligning holes in the forms to the printed matter is of considerable consequence.

While presses of any type are adjustable and great precaution may be exercised in the operation of such presses, still I have found that without some accurate guide which can be continuously observed by the press man, there is likely to occur a considerable accumulation of error before it can be observed andcorrected.

In printing presses where wide webs 'of paper are printed upon, as above noted, thus providing space for printing several plates, it is important that all of these plates align with each other, and that they be absolutely parallel with the press, and also that the press operates only a certain specific distance each time, as may be specified, and for which the press has been set. The number of forms necessary to fill in the wide printing web are locked up in a chase and any slight shifting about of the plates in the chase must be corrected at once to avoid wider shifting and, as has been noted, accumulation of error.

It is the object of my invention to apply to the paper coming froma press, more par ticularly of the special kind noted, a straight edge which will be adjustable to or utilizable with different pieces of work, and will provide an accurate guide for the operator.

In manifolding paper, of a certain type, there are holes punched in the forms for subsequent engagement vwith feeding and aligning pins, and the spacing of these holes and the position of them on the forms must also be closely watched by the operator. My device I also use for this purpose, and for this reason, in the drawings, I show it as applied to the forms after they have been both printed and punched.

I accomplish the above objects and other advantages to be noted by that certain construction and arrangement of parts to be hereinafter more specifically pointed out and claimed.

In the drawings,

Figure 1 is a perspective view of the end of a manifolding paper printing press, showing my invention applied thereto.

Figure 2 is a front elevation of my device.

Figure 3 is a plan view illustrating the straight edge byitself lying over a web of paper.

The press is merely indicated by the frame 1, over which passes a web of paper which has been printed into two like forms crosswise thereof, as shown at A and B.

After passing-to the forward or delivery end of the machine, the paper web runs over a guard and idler roll device 2 and thence is wound up on a drum 3.

My newndeviceis shown as mounted over the end of the press frame, so that the paperpasses beneath it, and isjerected on standin p te. tt it ha ards l, 4:, accurately mounted at the sides of the bed.

These standards are braced together by a rod 5 in the special device shown in the drawings, and carry a revoluble shaft 6 from which the straight edge is suspended. This sh ft is controlled in its position by a finger piece or wheel 7 mounted on its end, and one or both oi the standards carries a set screw 8 which screws into the shaft and locks it in desired positions in the standards.

From the shaft depend the desired nui'nber of arms 9, in the lower ends of which is rotatably mounted a shaft 10. This shaft 10 is intended to rock freely in the arms 9 so as to permit the straight edge to maintain an even keel at all positions of adjustment. 7

The straight edge 11 is mounted on the shaft 10 by means of arms 12 set fast on both elements 10 and i1, and underneath the knife, as a convenient term of rest, I may mount knobs 13, which will lie on the paper supporting guard :2 at the end of the press.

It will be observed that I have merely attempted to describe above one convenient and simple form of mounting for a straight edge, and that the exact construction and position over the forms issuing from a press must be altered to suit various conditions.

As a special form of straight edge adaptable for use with a multiple width print ing press for manifolding paper, I show in Figure 3 the straight edge 11 having graduations of a scale thereon and bearing slidably a number of arrow indicator devices. Thus there are bands 14 around the straight edge, which bands are slidable thereon and carry small set screws ll at the rear end, which bear on the back of the straight edge. On the forward end these bands carry pointers, 15 which come down into close proximity with the paper.

Describing the operation of my invention as applied to manifolding paper, it will be noted that when a press run is started, the paper is run through it until it "comes printed and, if desired, punched asat l5 under the straight edge. The operator then places thestraight edge by freeing and revolving the upper. shaft in its journals in the standards until the edge lies along ome convenient eross line in the printin If, upon doingthis, it is' discovered that the cross line does not form air-exact right angle direetion to the press, the pressisfreset until it does so.

The press man may then start his press and watch the straight edge and pointers to see that the operation remains perfect. The adjustability of the straight edge enables him to bring some printed line or other mark on the paper in exact correspondence with the guiding edge and the "fact that the edge indicates a certain line on the term enables the operator to tell it an intermittently feeding press is issuing the correct length of form.

The even keel of the straight r is main tained by the knobs on the ends resti 1 some sort of bed or support. and by th pivotal mounting of the blade on the lower ends the arms. The body ot the straight edge may take difierent angles, but the guiding edge thereof will always be close to the paper. thereby avoiding parallax.

Having thus described my invention, what I claim new and desire to secure by Letters Patent, is

1. In combination with a printing. press adapted to print and feed a portion of paper, a straight edge mounted in desired alignment across the path of the paper as it comes from the press, whereby the alignment of the printing on the paper may be observed.

2.
