IMPROVEMENT IN MACHINES Fon RULING PAPER.

Specication forming part of Letters Patent No. 10,492, dated February '7, 1854.

To all whom it may concern.-

Be it known that we, JOHN MCADAMS and WILLIAM McADAMs, both of Boston, in the county of Suffolk and State of Massachusetts, have invented certainl new and useful Improvements in Machines for Ruling Paper; and I do hereby declare that the following description, taken in connection with the accompanying drawings, hereinafter referred to, forms a full and exact specification of the same, wherein w'e have set forth the nature and principles of our said improvements, by which our invention may be distinguished from others of a similarclass, together with such parts as we claim and desire to have secured to us by Letters Patent. V

The figures of the accompanying platesy of drawings represent our improvements.

In Plate l, Figure l is a plan 'or top view of our machine. Fig. 2 is a detail view, which will be hereinafter referred to. In Plate 2, Fig. 3 is a vertical .section of the machine, taken in the plane of the line A B, Fig. 1. Flg. 4 is a vertical section taken in the plane of the line C D.

The principal result secured by our improvements is the ruling of both the horizon tal and vertical or up and down lines of the paper 1n passing it once through the machine, thereby effecting a great saving in time, and

alsofperforming the work with the greatest regularity and nicety. This desideratum is secured in our machine byV feeding the paper along till the first set of lines are ruled, and then, by a peculiar arrangement of mechanical devices, changing the direction in which the paper is moving, so as to take it o at right angles to its former course and feed it to another set of pens, which rule the crosslines. We have also made an essential improvement in the manner of lifting the pens from the paper, so as to leave any desired width of heading. This is effected by our improvements, not by the force of the edge of the paper abutting against mechanical devices Which lift the pen-holder, as sometimes practiced in these machines, and which is obj ectionable for many reasons, but by a peculiar gage which, at the time of lifting the pens, receives its motion from the motion of the feedroll and not from the edge of the paper.

a a d b b b in the drawings represent the two parts of the frame-work of themachine,

arranged at right angles to each other. The paper is fed in upon a platform@ cto the first roll d, being kept upon'the periphery of this roll by a band e e, which passes around three small guide-rolls fff. The under side of the paper is thus ruledby being brought against the first set of pens g g', which are supplied with ink in the usual manner from a trough h. The paper then-passes, as shown by the arrows in the drawings, to the roll t', being kept upon the same by the band 7c k of the guide-rolls Z Z Z, and thus is ruled on the upper side by the second set of pens m m. One s et of lines being thus ruled on both sides of the paper, it then passes onto the conducting bands or cords 'It n, dac., and across the rolls o o to another set of bands p p, which guide it to the traveling band q q, running at right angles to the bands n n. The sheet in passingonto this band q q strikes against the revolving drums r r r, the action of which, together with that of the band q q, causes it to travel in a direction at right angles to its rst course onto the roll s and the conducting bands t t, which guide ity to the roll fLaupon which it is held, as inthe first instance, by a band running around three guide pulleys or rolls. The under side of the paper is thus brought against another set of pens o o, which may be filled with a dierent colored ink, if desirable. As the. paper is moving in a direction at right angles to its first course, it vwill be seen that the pens o v will rule the cross-lines on the under side of the paper at right angles to those first ruled. The sheet then passes, as shown by the arrows in the drawings, around the roll w, when the cross-lines on the upper side'will be ruled by the pens 0000. It then passes,being wholly ruled, over another set of conducting-bands y y and the square revolving roll A and drops into the receiver B.

The different rolls, dac., have motion imparted to them by pulleys, bands, dac., and the gear-wheels C C, as will readily be understood without further'explanation by reference to the drawings.

We shall now proceed to describe the manner in which the pens are lifted just previous to the ruling of the up and down or vertical K lines, so as to leave Aa proper heading to the sheet. The devices for effecting this are particularly represented in Fig. 2, Plate l, which is a side elevation of the same. The edge of the sheet as it is fed in abuts against a bent movable tongue D, which is attached to the inside of a roller E, and is retracted by a spring F and turns upon a pivot at F. The roller E has a portion of its periphery cut off at G, so as to prevent its bearing upon the feed-roll d, before referred to. Another p0rtion of theroller E has a cam or projection -G upon it. As the paper passes along, its edge strikes against a flange on the bent tongue D, which bears against a shoulder in the roller E, and thus turns the said roller on its aXis, and the bent tongue, turning on its pivot, will be forced up and away from the periphery of the roller. As soon as the roller has turned sufficiently, the cam projection of the same will be brought to bear upon the roll d and turn with it, so as to lift the arm H. This arm H passes through a journal in the vertical bar I, on which slides a box K. which is fastened to the pen-holder J by a set-screw, so that the raising of the arm H also lifts the pens. Thus it will be seen that the edge of the paper as it passes along turns the roller E only enough to bring its cam projection to bear on the feeding-roll d, and that the whole force expended in lifting the pen-holder is derived from the feeding-roll, which, as soon as the cam projection of the roller bears upon it, completes the revolution of the said roller and lifts the pens. The roller E is prevented from turning till it is struck by the edge of the paper by a slight spring L, which bears upon the said roller.

It will readily be seen that when the cam projection of the roller E ceases to bear upon the feed-roll the pen-holder (which turns upon a proper journal) Will drop again and allow the pens to bear upon the paper, so that a heading will be left proportionate to the length of the cam projection. The pens which rule the vertical lines on the upper side of the sheet are lifted at the proper time in a similar manner, and as the length of the heading depends upon the position of the roller d this length can be varied by sliding the arm Hin its journal, so that more or less of the sheet Will be fed in before its edge strikes the tongue of the roller.

As these machines have heretofore been constructed, the pens,when not resting upon the paper, rest upon a traversing apron, keeping the said apron wet and thus often soiling the sheet. To avoid this the feed-rolls d, &c., in our machine are grooved, so that the pens, when not resting upon the paper, come dithem, so that no ink is received by the feedrolls.

We have also made an important improvement in the shape of the roll which carries the paper to the receiver B. This roll is usually cylindrical in shape, and as the sheets, when ruled, are a little Wet., they often stick upon one another in falling and do not form regularlyinto a ream in the receiver B. The guide which We use for this purpose is represented at A and may be of a square or any polygonal shape, and as it revolves its angular projections give a slight vibratory mot-ion to the sheet, which prevents its sticking immediately upon the preceding sheet in the receiver. of lines is ruled, may pass exactly straight to the pens which rule the lines at Vright angles to the first ones, it is carried by the conducting-bands it, (before referred to,) which are arranged so as to converge toward the side frame-Work b b, against a proper guide in the said frame-work, so that its side edge will bear against the guide and thus carry the sheet in a straight line to the pens. l

Ve have also made an improvement in the pens or conductors which carry the ink to the paper. These pens, as heretofore constructed, have required frequent repairing, as their points wear off and prevent their forming a clear line. Our improvement consists in tipping the points, which we round off with rhodium, and covering the whole pen with a coating of silver, which coating takes off the polish or grease of the metal (which retards the passage ofthe ink) and more readily conducts the ink to the paper. The points being tippedwith rhodium prevent them from wearing off, so that they will last much longer and produce a more even line than those commonly used,while the pens form a never-failing conductor for the ink.

Having thus described our improvements, we shall state our claims as follows:

What we claim as our invention is l. A machine for ruling paper, in which both the horizontal and vertical lines of the sheet are ruled in passing once through the maj chine by any arrangement of devices which carries the sheet after one set of lines is ruled in a direction at right angles toits first course to another set of pens which rule the sheet across the lines first made.

2. Changing the direction of the movement of the sheet after passing from the first setv stantially as above described. rectly over these grooves, but do not rest upon 4. Forming grooves in the feed-rolls, so that the pens may rest over these grooves and not upon the rolls between the passage of the different sheets, as above set forth.y A

5. Guiding the sheet straight to the second In order that the sheet, after one set set of pens after the direction of its movement is changed by means of the converging bands, which carry the edge of the sheet against a proper guide or against the side frame-work of the machine, as hereinabove specified.

G. Forming the last roll, which carresvthe sheet after it is ruled to the receiver, of a polygonal or angular shape, so that its revolution may give a vibratory motion to the sheet, for the purpose above specified.
