JAMES ROWE, OF CHICAGO, ILLINOIS.

NUMBERING ATTACHMENT FOR PRINTING-PRESSES.

SPECIFICATION forming part of Letters Patent No. 768,773, dated August 30, 1904.

Application filed August 7, 1903.

To a, whom, it ntcty concern:

Be it known that I, J AMES ROWE, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Numbering Attachments for Printing- Presses; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to a novel construction in a numbering attachment for printingpresses, the object being to provide a device of this character of simple and durable construction and eflicient operation which is particularly adaptable for special purposes; and it consists in the features of construction and combinations of parts hereinafter fully described and claimed.

In the accompanying drawings, illustrating my invention, Figure 1 is a fragmentary side elevation showing part of a printing-press provided with a numbering attachment constructed in accordance with my invention, the latter being shown in end elevation. Figs. 2 and 3 are fragmentary views in elevation of my said numbering device. Figs. I and 5 are fragmentary end elevations, on an enlarged scale, showing the mechanism for turning the numbering wheel or wheels in two positions. Fig. 6 is a detail transverse section, on an enlarged scale, on the line 6 6 of Fig. 2, showing means for varying the printing position of the numbering wheel or wheels relative to the cylinder by which they are carried. Fig. 7 is a detail transverse section, on an enlarged scale, on the line 7 7 of Fig. 2, the crescent cylinder, &c. being removed. Fig. 8 is a section of same on the line 8 8 of Fig. 7 Fig. 9 is a fragmentary detail longitudinal section of a slightly-modified construction of my device. Fig. 10 is a transverse section of same on the line-1O 10 of Fig. 9.

In illustrating my invention I have shown the same and in the following pages will describe it as applied to a printing-press of my own invention forming subject of a companion application filed simultaneously herewith,

having chosen this for greater convenience;

Serial No. 168,654. (No model.)

but it will be readily seen that my present device can be applied with equal advantage to almost any printing-press now used.

In said drawings the frame 1 of the printing-press is provided with a segmental impression-bed 2, at each side of which is a rack 3. Mounted on trunnions concentric with said bed 2 is an oscillating frame 4, receiving its motion from a reciprocating piston 5, actuated in any suitable manner. J ournaled'in bearings 6 in the outer end of said oscillating frame 4 are the trunnions 7 of what I will term a cylinder 8, which carries the numbering mechanism, and rigid with said cylinder 8 are spur-gears 9, meshing with said racks 3, whereby said cylinder is revolved alternately in op posite directions. Said cylinder 8 is hollowed out, so as to leave a crescent-shaped wall, or, in other words, to provide a cylindrical chamber 10, which is eccentric to said cylinder 8 and within which the numbering-wheel 11 fits and revolves; The latter is rigidly mounted on a shaft 12, which passes eccentrically through the trunnions 7 and at one end carries a spurgear 13, which is rigid therewith. Mounted on the trunnions 7, adjacent which said gear 13 is located, is a plate 14:, having a tapered arm15, which carries a stud 16, on which a ratchet-wheel 17 is journaled, which is rigid with a spur-pinion 18, meshing with said spurgear 13.

Pivotally mounted in the free end of said arm is the free end of one arm of a bellcrank lever 19, in the elbow of which a dog 20 is pivotally mounted, which engages said ratchet-wheel 17 Said dog is provided with an arm 21, in the free end of which a plunger 22 is pivotally secured, which passes at its free end through a collar 23 on the free end of thexarm'l5 of said plate 14 and on which aspiral compression-spring 24: is coiled, which bears at one end on said collar 23 and on its other end against a collar 25 on said plunger, thereby normally holding said dog 20 in engagement with said ratchet-wheel 17. In order to prevent said dog 20 from turning out of engagement with said ratchet-wheel, a second collar 26 may be secured to the projecting end of said plunger to prevent the latter from pulling out of said collar 23. On said plate 14 is a projecting arm 27, in the free end of which is an opening through which one end of a plunger 28 passes, said plunger being pivotally connected at its other end with the IP66 end of the other arm of said bellcrank lever 19, the latter carrying a stud on which an antifriction-roller 29 is journaled, which travels on the inner face of a cam 30, rigidly secured to said oscillating frame 4. The said plunger 28 is provided with a collar 31, between which and said arm 27 a spiral compression-spring 32 is interposed, which serves to hold said antifriction-roller 29 in contact with said cam 30.

The said cam 30 consists of a plate provided with an opening which is practically semicylindrical at one side and enlarged at its other side, so that in traveling around on the wall of said opening said antifriction-roller 29 would be deflected twice during one revolution; but as said cylinder 8 is rocked said roller 29 is deflected inwardly each time the frame 4 approaches one limit of its movement, thus turning the lever 19 on its pivot and causing the dog 20 to revolve the wheel 17 a distance equal to that between two adjacent teeth of said wheel.

Assuming that the numbering-wheel has twenty-five divisions and the spur-gear 13 has lifty teeth, then the pinion 18 would be provided with sixteen teeth and the ratchet-wheel 17 with eight teeth, so that the numberingwheel would thus be revolved adistance equal to that between two adjacent divisions each time that the ratchet-wheel17 is actuated. A spring 33, secured to said plate 14, enters the notches of said ratchet'wheel 17 successively and serves not only to hold same against reverse movement, but also acts to compensate for any lost motion of the dog 20 to insure proper position of the numberingwheel. The stroke of the oscillating frame 4 is such as to impart to the cylinder 8 more than a halfrevolution at each movement and less than one and one-half revolutions, so that the position of said numbering wheel cannot be shifted more than once for each stroke of said frame 4.

Fig. 4 shows the oscillating frame 4 practically at the middle of its stroke, while Fig. 5 shows same at one limit of its stroke, both said figures showing clearly the relative positionsof the numbering-wheel-shifting mechanism.

The said numbering-wheel 11 is longitudinally movable on said shaft 12, the latter be ing provided with a longitudinal rib or key 34, entering a corresponding groove in said wheel 11, the hub of the latter being provided with a set-screw 35, hearing on said rib or key 34.

It will be noted that, as indicated by the dotted pitch-line 36 in Fig. 6, the cylinder 8 is not a true cylinder, the walls 37 at the ends of the chamber 10 being eccentric to said cylinder and projecting beyond the radius of said cylinder. The printing-surface of the numbering-wheel is practically flush with the outermost points of said end walls, extending only so far beyond the latter as is necessary to effect printing; but, as willbe obvious, only one division of said numbering-wheel can be in printing position at one time. The surface of said cylinder serves as an ink-distributing surface which coacts with the inking-rollers 38 to properly spread the ink. The said inking-rollers are journaled in the free ends of arms 39, which are pivotally mounted on tie-rods 40, connecting the ends of the arms of the oscillating frame 4 on opposite sides of the printingbed. Spiral springs 41, engaging said arms at one end, are coiled on said rods 40 and at their other ends are secured to adjustable collars 42 on said rods, said springs serving to hold said inkingrollers 38 in contact with the surface of said cylinder 8. Said inking-rollers 38 are fed from an inking-roller 43, which in turn receives ink from other rollers. (Not herein shown.)

It will be noted that in Figs. 2 and 3 I have shown two of said cylinders 8. It is my intention to use both and have one of same carry a numbering-wheel bearing the odd numbers and the other the even numbers. The devices for actuating the numbering-Wheel of the second cylinder are located on the opposite side of the frame 4 and correspond exactly with the devices hereinbefore described.

The said spur-gears 13 are held rigid with the cylinder 8 by means of a set-screw 44 entering screw-threaded openings in said gears and passing through segmental slots 45 in said end walls 37 of said cylinder, thereby enabling said cylinder to be adjusted relatively to the impression-bed of the press to vary the point thereon at which the numbering-wheel prints, so that the position of the number relatively to the other printed matter on the sheet can be adjusted. at will. The said numberingwheel 11 is provided with a circumferential flange 46 on one edge, the inner face of which is undercut on a bevel in order to receive the beveled edges of the platesor type 47 containing the numerals to be printed. At their opposite edges said plates or type 47 are clamped in position by means of small chan neled plates 48, having one of their flanges beveled at its free end to engage the beveled edge of the plate 47, said plates 48 being secured in place by means of set-screws 49 entering screw-threaded openings 50 in said wheel 11.

The devices hereinbefore described are intended to print the numerals ranging from one to fifty or to one hundred on sheets, such as purchase or sale checks, &c., which are intended to be put up in blocks of fifty or one hundred, so that after having completed one series it will begin a second series, and so on.

IOU

If, however, it is desired to print numbers consecutively to any desired denomination, my device may be easily modified to accomplish this. Figs. 9 and 10 illustrate such modification, the consecutive numbering device 51, consisting of aplurality of numbering-wheels suitably geared together to advance the numeral one unit at each operation, being mounted on a longitudinal grooved shaft 52, which is rigid with the cylinder and on which the spur-gear 53, connected with the unit-disk of the numbering device 51, is loosely mounted. On the counter-shaft 5a, which carries the ratchet-wheel 17, is a spur-gear 55, meshing with said gear 53 and actuatingthe latter. The said numbering device 51 and the gearing for actuating same are held between two plates 56, forming a frame therefor, and are longitudinally movable on said shafts 52 and 5 1. The same means for adjusting the cylinder 8, carrying said devices, relatively to the impression-bed are employed, as are shown in Fig. 6, thus enabling the number to be printed at any desired point relatively to the other printed matter on the sheet.

The operation of my device is as follows: As the frame 4. oscillates the cylinder or cyl inders 8 are rotated back and forth, the numbering-wheels being caused to print a new number at each movement and always when the frame 4is about midway between the limits of its movement. The press herein shown is so arranged that each time that the frame 1 approaches either limit of its movement the continuous web to be printed is shifted to present a fresh surface, the mechanism for effectcation and being, therefore, omitted. Hence each time that one or both the cylinders 8 pass over said web they print at different points on its surface. l/Vhere the two cylinders are used, one of which prints the even and the other the odd numbers, said numbers must obviously not appear upon the same section of the web, so that in this case the web is shifted a distance equal to the combined length of two sections or sheets at each opera tion, so that two of said sections or sheets are simultaneously numbered at each operation. The inking-surface of the cylinder does not come into contact with the web owing to the fact that its radius is smaller than the radial distance from its axis to the printing-surface of the numberingwl1eel.

This manner of printing the numerals on the sheet is very much superiorto the usual method employed, in which the numbering device is reciprocated toward'and away from the impression-bed, for the reason that the numbering device is relieved of the jar and the great pressure to which it is otherwise subjected, thereby rendering it more durable.
