Specification of Letters Patent.

Patented July 30, 1912.

Application filed March 29, 1912. Serial No. 687,091.

To all whom it may concern:

Be it known that I, DUNCAN CAMERON, subject of the King of Great Britain, residing at Edinburgh, Scotland, have invented certain new and useful Improvements in Paper-Ruling Machines, of which the following is a specification.

This invention relates to the ruling of paper from the web or reel but more particularly to the ruling of transverse lines in machines of that type wherein the paper, after being longitudinally ruled, is brought to rest while the transverse lines are ruled bymeans of a laterally-traveling carriage carrying the ruling devices, said carriage moving first from one side to the other to rule one set oflines, and then returning after the paper has been fed forward in order to rule the next set.

The principal object of the present invention is to provide improved means for interrupting the continuity of the ruling in order to produce blank spaces or headings in the sheets, known technically as stop work. This object is proposed to be attained by placing upon the sheets where the ruling is to be interrupted, strips or masks of suitable material over which the ruling devices travel when the ruling carriage is actuated, thus leaving the portion of the paper lying below the masking strips blank or unruled. To provide against irregularity in the position of the blank spaces when 1 the carriage is moved in opposite'directions,

due to the momentum carrying the ruling.

devices past the edge of the masking, strips before they come in contact with the paper, the said strips are mounted upon a frame which has a small lateral movement automatically imparted to it each time the motion of the carriage is reversed so as to insure the absolute uniformity in the position of the blank spaces of successive portions of the paper.

Figure 1 of the accompanying drawings represents a plan of a ruling machine embodying the present invention. The frame carrying the masking strips is shown in the position it assumes while the transverse ruling carriage is moving from right to left. Fig.2 is a similar view, but shows the shifting frame moved toward the left for.

the travel of the carriage from left to right. Fig. 3 is a transverse section through the machine showing the 'cam mechanism for moving the carriage and shifting theframe carrying the masking strips. Fig. 1 is a similar view but shows the frame shifted over to the left for the travel of the carriage from left to right. Fig. 5 is a side view of the machine. Fig. 6 is an enlarged transverse section, showing more clearly the construction of the carriage and the arrangement of the ruling devices and inking mechanism. This view shows the carriage traveling from right to left. Fig. 7 is a similar View, butwith the carriage traveling fromv leftzto right. Fig. 8 is a longitudinal section showingthe carriage and ruling devices and inking roller in elevation.

The same reference numerals indicate cor responding parts in each-of the figures of the drawings.

1 is the laterally traveling carriage carrying upon the spindle 2 the ruling devices 8 here shown-as disks by which the transverse lines are ruled upon the paper each time the latter is periodically brought to rest after having been longitudinally ruled by another set of disks carried by the machine. The said carriage 1 slides upon a pair of parallel guide rods 4 carried by

end brackets

5, 5, and is moved from side-toside, at the proper times, by means of a chain 6 having its ends attached to opposite sides of the carriage, and passing over sprocket wheels 7, 8, upon the frame and around a sprocketv wheel 9 fixed upon a shaft 1.0 which is supported at one end by a single bracket 11, and at the opposite end by a pair of

brackets

12, 12. The said shaft 10 carries, between the

brackets

12, 12, a toothed pinion 13 gearing with a vertically moving rack 14: which is guided in its movement, by a flanged roller 15 upon a spindle supported between theout-er ends of the

brackets

12, 12. The rack 14 is carried by the upper end of a vertical rod 16 whose lower end is provided with a pin 17, engaging in a slot. 18 in a lateral lever arm 19 mounted at its inner end upon a pivot 20. This rocking arm 19 carries upon one side a roller 21 which engages in a cam groove 22 in the face of a cam 22 fixed upon a revolving cam shaft 23 driven from any convenient part of the machine. As the cam revolves it lifts the arm 19 which, in turn, raises the rod 16 and rack 141, which latter rotates the shaft 10 and sprocket wheel 9, whereby the chain 6 causes the carriage 1 to move laterally inorder to rule riage.

the transverse lines upon the paper. The cam 22 is so set that it lifts the arm 19 after the continuous length of paper has been fed forward in the longitudinal direction and brought to rest.

The carriage 1 supports the rubber-faced inking roller 2a supplied with ink from a wick or pad 25 carried by a holder 26 and kept saturated with ink by suitable means, such as from a reservoir upon the carriage. The roller 24 is provided with trunnions 27 at opposite extremities which turn within open slots 28 in the ends of lever arms 29 fulcrumed at 30 to the frame of the car- The roller is kept in contact with the peripheries of the ruling disks 3 by springs 31. The ends of the spindle 2 carrying the said disks may, if desired, be mounted in yielding bearings.

To stop or interrupt the ruling where the paper is required to be left blank, longitudinally arranged masking strips 32 of thin sheet copper, celluloid, or other suitable material, are carried by a frame 33 superimposed upon the ruling table 34 and under which the paper passes, so that the strips 32 lie upon the surface of the said paper. The said masking strips are attached to the frame by clamping plates 35. As the carriage travels from side to side, the disks 3 run over the masking strips and leave the portion of the paper lying beneath them plain or unruled. Owing, however, to the momentum of the carriage, the disks, after leaving the masking strip 32, fall upon the paper at some distance beyond the edge of the strip (as shown by a, Figs. 6 and 7) this distance being greater than that between the front edge of the strip and the point when the disks leave the paper, (indicated by 1)). Consequently if no means were provided for correcting or compensating for this effect of the momentum, the edges of the blank spaces formed during the movement of the carriage in the one direction would be displaced laterally with respect to the edges of the corresponding blank spaces formed on the next portion of the paper during the return movement of the carriage. To correct this the frame 33 carrying the masking strips 32 is arranged to be automatically given a small lateral motion each time the carriage 1 is reversed, so that the strips are brought nearer to the said carriage by an amount equal to the difference between the distance that the disks travel beyond the edge of the strip before touching the paper due to 'themomentum, and the distance between the front or leading edge of the strip and the point at which the disks leave the paper on meeting the strip, that is, the difference between the distances a, b. By this means absolute uniformity in the position of the blank spaces can be obtained.

To impart the lateral movement to the frame one of its rails is provided with an upstanding lug 36 which is connected by a jointed rod 36 to a vertical arm 37 upon a rocker shaft 38 which carries a horizontal arm 39-connectcd to a rod 40 whose lower end is forked and carries a roller l-l adapted to be engaged by a cam 42 on the shaft 23, said cam being timed to give the necessary movement to the frame 33 at the proper moment, that is, when the carriage reaches the end of its travel. A spring 43 gives the return movement to the frame.

44 is an adjustable stop, for limiting the lateral movement of the sliding frame 33. Its position can be adjusted according to the speed at which the ruling is effected.

Having fully described my invention, what I desire to claim and secure by Letters Patent is 1.
