RULlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 370,041, dated September 20, 1887.

Serial No. 182.092. (No model.)

To all whom it may concern..-

Be it known that I, Isaac M. BROWN, aeitizen of the United States, residing at Columbus, in the county ofBartholomew and State of Indiana, have invented a new and useful Improved Ruling-Machine, of which the following is a specification.

My invention relates to an improvement in machines for ruling paper.

The object of my improvement is to provide a machine for ruling paper, which may be cheaply made, so as to occupy butlittle space, and having improved means for lifting the ruling-pens and for drying the ruled lines, all as hereinafter fully explained.

The accompanying drawings illustrate my invention.

Figure l is an elevation; Fig. 2, a plan, having the ink-fountain and pen-bar removed; Fig. 3, a section at a, Fig. 1; Fig. 4, a longitudinal section of the ruling-cylinder. Fig. 5 is a partial enlarged elevation showing the operation of the pen-lifter. Fig. 6 is apartial end elevation showing the adjustable bearings for the cylinder.

A is a smooth cylinder arranged to revolve in suitable vertically-adjustable bearings, be, Fig. 6, in a frame, I), and having at each end several annular clamping-rings, c c, mounted on reduced portions of the cylinder, and clamped thereto by suitable bolts and thumbnuts. Said clamping-rings are for the purpose of securing to the cylinder segmental annular cams, like d and e, a device well known in this class of machines, for operating the pen-lifting mechanism. The peripheries of the cylinder and the rings are graduated, and the graduations are marked, as illustrated in Fig. 1, to facilitate the setting ofthe segmental cams.

B is the pen-bar, mounted on a rockingshaft, f, above the cylinder A, and adapted to hold a series of ruling-pens, g. Said bar is rocked, and the ruling pens thereby lifted from contact with the periphery of the cylinder, by means of cam (1 coming in contact with and raising an arm, h, secured to the shaft in the usual well -known manner. A series of friction feedwheels, j j, are mounted on a shaft, k, so as to be in constant contact with the periphery of cylinder A. Said shaftis arranged to revolve with the feed-wheels,which are turned by the turning of the cylinder,and is provided with a series of fine circumferential grooves,which carry endless string belts, which pass over a second similarly-grooved shaft, m, and in contact with the periphery of cylinder A, for the purpose of holding the paper closely thereto in the process ofruling. A second series of friction feed-wheels, n n, are mounted on a shaft, 0, which revolves in bearings in a pair of short arms, pp,which are secured to a rocking-shaft ,q, resting in bearings on the main frame. Endless string belts run from shaft 0 to shaft it, which keep the paper under the feed-wheels a a close to the cylinder Auntil the feedrollers on shaft k receive it. Shaft q is rocked, and wheels or a are thereby lifted from contact with cylinder A by means of a cam, S, adjustably secured to the cylinder by the clamping-rings c,and engaging an arm, 1", secured to the shaft.

The ink-fountain consists of a case, t, removably secured to the pen-bar shaft and adapted to receive and hold a series of bottles, a u, containing ruling-ink. Said bottles lie on their sides with their necks projecting through one side of the case, as shown, and each bottle is provided with a wick, wt, of woolen or other suitable fiber, which dipsinto the ink in the bottle and passes through a suitable opening in the cork, which closes the mouth of the bottle, to one or more of the ruling-pens, thereby conducting the ink by capillary attraction in a constant flow to the pen.

C D are a pair of hollow cylinders, C having an outer covering of blotting-paper, and D being also covered with blotting-paper or other slightly-yielding material. The lower cylinder, D, is arranged to revolve in permanent hearings on the main frame. Cylinder C rests on D, and is arranged to revolve in swinging bearings 22 12. Motion is given to C by a belt, to, passing from a pulley on the same shaft with cylinder A. Said belt drives a pair of spur-gears, a: 00, one of which is secured on the shaft of cylinder C, and the other turns on a stud at y. Cylinders C and D are for the purpose of rapidly dryingthe ruled lines, and may be used at a normal temperature; or they may be heated by introducing steam into their interiors or by other well-known means.

E is an inclined table on which the ruled papers are delivered from cylinder A, and pass by gravitation to the drying-cylinders.

It is often desirable in ruling a series of lines in certain classes of work to make some of the lines in short sections with unruled spaces between, while the rest of the lines of i the series are continiious. For this purpese I raise the points of one or more of the rulingpens while the others are still on the paper by means of the following mechanism:

1 mount one, two, or more rocking shafts, F, above the rulingcylinder and behind the ruling-pens. These shaftsare independent of each other and rest in bearing on the frame and in a central bearing, 8, which is held by permanent rods 29, secured to the main frame above and below the rocking shafts. Said shafts are provided with one or moresliort arms or pen lifters, 2 2', which are adjustably seciire'd to the shaft by means of a springclamp, 3. lanai-111,4, is permanently secured to shaft F in such position as to be engaged at its free end by, a cam or cani's,,e, on the cylinder A. Spring 5 holds arm 4 norinally downward against the cylinder. The short arms 2 are bent at their free ends and adjusted so as to pass partly arounda'nd engage the underside of the penandhold th'e'point ofthe' pen up clear of the paper when arm 4 is not engaged by the came, as'seen in Fig. 5 in both positions, the pens being sufficiently elastic to admit of being bent to that extent without permanent set. Whenarm 4 is raised bythe, cam, a'rms2are depressed and the pens allowed to spring back to their normal position in contact with the paper, r

, It will be observed that the mechanism just described for lifting individual pens is entirely separate and independent from that for lifting the whole. series of pens, so that any required number of theseries of pens may be lifted while the rest are at work, i It is rny purpose in practice to use several shafts like F, with its arms 2 and 4, so that different pens of the series may be lifted at different times, cams for that purpose being used at opposite ends of the cylinder. I I v The operation of my machine is as follows: Shaft 0 being raised by the cam S, and thepenbar with it's-pens being held up by ca'm d, and the blank sheets to be ruled resting on feed-board H,'the edge of one of the sheets is placed on cylinder A, under the feed-wheels n, and adjusted to a guide which is attached to shaft g on the opposite side to the feed-wheels n n, and is lowered as the feed-wheels rise, and is raised as they fall. The cylinder is now turned, by means of crank I, in the direction indicated by the arrow; As cam S passes out of engagement with arm 1', wheels it fall, and the sheet is seized between said wheels and the cylinder and carried forward under the endless string belts connected with shaft 70 and under feed wheels j. Cam d passing out of engagement with arm-h, the whole series of pens fall, and all, except those sustained by coming in contact with arms 2, as before explained, come in con'tact with the paper, an'd'the ruling COID- mences, When cam e engages armd, these last-mentioned pensjcoin'ealso into action by the lowering'of arms 2, which will be raised by spring 5, when said arm land cam pass out of engagement, The sheet, when ruled, passes from cylinder A downthe inclined table E, and-is seized by the drying-rolls, and, passing between said rolls, is deliveredto a suitable receptacle. The long and cumbersoihe system of conveyer-belts for drying the sheets heretofore used is thus dispensed with,

and the paper is ruled, as described, with lines of different lengths at one operation, and with much greater speed than heretofore.

Iclaim as my invention In a ruling-machine, the combination of the main frame, the cylinder A, arranged to re- Volve and carrying the earn 6, therulin'gpen arrangedt'o stand normally with its point resting on the pe'riph'ery of said cylinder, the

shaft F, having arm 4 ar'ranged to engage said cam, the spring 5, arranged to hold said 'ar'm normally in contact with the cylinder, the clampfi, mounted on said shaft, and the penlifter 2, secured in said clamp and arranged to engage the pen nearits point, all arranged to co-op'erate substantially, as described, whereby the point only'of the pen is lifted at intervals,

for the purpose specified. 7 H
