UNITED FREDERICK HART, OF POGI-IKEEPSIE, ASSIGNOR TO D. H. BURRELL'& OO., OF LITTLE FALLS, NEW YORK.

RULiNc-MACHINE.

SPECIFICATION forming part of Letters Patent'No. 497,472, dated May 16, 1893.

Application led June 17, 1889- Serial No. 314,640 (No model.)

To all whom t may concern: Be it known that I, FREDERICK HART, a subject of the Queen of England, residing at Poughkeepsie,in the county of Dutchess and State of New York, United States of America, have invented new and useful Improvements in Ruling-Machines, of which the following is a specification.

This invention relates to that class of ruling machines in which rotating ruling` rings'or disks are employed, and has for its object `to produce a simple, compact and efficient inachine of this character. 4

In the accompanying drawings consistingv of three sheetsz-Figure l is an end elevation of my improved ruling machine partly in section. Fig. 2 is a vertical cross section thereof. Fig. 3 is a vertical longitudinal section thereof. Fig. 4 is a front elevation of the machine. Fig. 5 is a top plan view thereof. Fig. 6 is a rear elevation of the machine. Fig. 7 is a top plan View of the upper ruling cylinder and its supporting frame.

Like letters of reference refer to like parts in the several figures. v

A represents the base plate of the machine,

and a d vertical frames secured to the base' tion of this sleeve forms. a hollow stud on which is mounted the pulley D by which the lower ruling cylinder is rotated. This pulley is held against lateral movement on the sleeve by a collar d which is secured to the outer end of the sleeve and projects into an annular recess in the outer side of the pulley, the outer side of which recess is closed by a detachable plate d. This plate is provided at its center with a square opening in which engages the square outer end of the driving shaft E of the lower ruling cylinder. This driving shaft passes loosely through the sleeve In the bearing a2 'is arranged a horizontal sliding bolt G which projects inwardly from the bearing and enters with its conical inner end a correspondingly shaped cavity formed in a bushing g which is secured' in the adjacent end of the sleeve F. This sliding bolt is pressed inwardly against the cylinder by a spring g which surrounds the stein g2 of the sliding bolt and is arranged in a casing gs secured to the outer side of the bearing a2.

lThe stem g2 of the sliding bolt is provided on the outer side of the casing with a thumb piece g4 by which the sliding bolt can be pulled outwardly when it is desired t0 remove the lower ruling cylinder.

H represents the ink fountain from which the lower ruling cylinder is supplied with ink, and which is arranged in rear of and below the'ruling cylinder, and above the base plate A. This ink fountain is provided at both ends with arms h which project forwardly between the side frames d d, and which are prolvided at their front ends with outwardly projecting lugs h resting upon set screws h2 by means of which the front ends of the arms can be raised and lowered. The frame formed by the ink fountain l-I and the arms his supported at its rear end by hooks h3 formed on the ink fountain, and resting upon upwardly projecting lugs h4 secured to the rear side of the base plat-e A.

I represents an ink ribbon or apron which is arranged lengthwise underneath thelower ruling cylinder B so as to bearl against the lower portions of the ruling rings b of the same and supply ink thereto. This ink ribbon is arranged lengthwise in front of the ink fountain H and its end portions are wound upon rollers t' which are journaled in lugs '1l' i2 formed respectively at the outer ends of the IOO arms h and the front wall of the ink foun` tain. These rollers are provided at their outer ends with ratchet wheels .l and pawls j so that the ribbon can be moved in the direction of the axis of the ruling cylinder and new portions of the ribbon be brought in contact with the ruling rings when required. The ink is elevated from the ink fountain to the ink ribbon by means of a broad wiel; 7c which is immersed with its lower end in the ink in the fountain and rests with its upper end upon the ribbon. The front wall of the ink fountain is provided with a curved lip 7c for supporting the upper portion of the wick. This wick is preferably constructed of fiannel, but it may be constructed of any other material which has the necessary capillary action.

L represents the cover of the ink fountain which rests in notches formed in the end wall of the fountain, and is separated at its front edge from the front wall of the fountain by a space suliicient to accommodate the wick 7i;`

and a clamping plate Zwhich bears against the rear side of the wick in front ot' the cover. This clamping plate is pressed against the wick and the latter against the front wall of the ink fountain by means of set screws Z', so

p that the ink feeding capacity of the wick can be increasedor reduced by decreasing or increasing the pressure of the clamping plate against the Wick by adj nsti ng the set screws Z.

M represents the upper ruling cylinder provided with ruling rings m and secured to a tube m which is provided in its ends with bushings m2 m3. lhe supporting devices of `the upper ruling cylinder are mounted in a horizontal U-shaped or bifurcated frame N which is composed of a plate n and forwardly projecting arms n n2 formed on said plate and carrying at their front ends bearings n3 n4. The frame N is pivoted near its rear end between the side frames a a by horizontal pivots O which are secured in openings formed in the elevated rear portions of the side frames. These pivots are formed with external screw threads and are secured iu the side frames by screw nuts applied to opposite sides of the latter. The inner conical ends of the pivots O enter conical recesses in the frame N. The front ends of the arms a n2 rest upon set screws p which are arranged in lugs p' formed upon the bearings d2 a3 of the side frames a a. screws the front portions of the arms n a2 can be raised and lowered to regulate the distance between the ruling rings which are arranged face to face or edge to edge so as to operate simultaneously upon opposite sides ot` the sheet of paper which is fed between the two ruling cylinders by suitable feed tapes or other devices which are not shown in the drawings. The operating and supporting devices of the upper ruling cylinder are identical in construction with those of the lower ruling cylinder, but are reversed in their arrangement, the driving pulleys of the two cylinders By adjusting these set being placed on opposite sides of the machine for the purpose of compactness in construction. The upper ruling cylinder is supported at one end by the sliding spring bolt Q arranged in the bearing n4, and at its opposite end by the sleeve R in the bearing n3.

r represents the driving shaft of the upper ruling cylinder, and r the driving pulley thereof.

The inking mechanism of the upper ruling cylinder is constructed like that of the lower ruling cylinder, and consists of an ink fountain S, ink ribbon s, wick s', clamping plate s?, cover s3, adjusting screws s, and rollers S5, upon which the ribbon is wound, and which are journaled in arms s and provided with ratchet mechanism S7. The upper ink fountain S is arranged above the frame N, and its ink ribbon s is arranged above the upper ruling cylinder, so as to bear against the upper portions of the ruling rings thereof. The rear portion of the frame composed of the ink fountain S and arms s is supported by hooks S8, formed on the ink fountain, upon lugs 39 formed on the plate a, and the front portions of this frame of the inking mechanism ale supported upon the arms n n2 by set screws# which are secured in the arms s, and rest upon the arms n n2.

The connection of the driving shafts with the ruling cylinder is to a certain extent fiexi ble, so that the shaft can springer change its position within certain limits, without causing a change of position in the ruling cylinder. The ruling cylinders are thereby en abled to remain in proper register or alignmeutalthough the driving mechanism of one or both of them may have been sprung out of alignment.

The frame in which the upper ruling cylinder is mounted rests loosely upon the lower stationary frame, and is free to rise when two or more sheet-s enter accidentally between the ruling disks, thereby avoiding injury to the disks by an excessive feed of paper, and preventing the paper from being cut by the ruling disks.

The fountain, ribbon, and all other supporting and operative parts of eachinking mechanism are so connected together that each inking mechanism can be removed completely from the machine for the purpose of cleaning or other purposes, without interfering with or changing the adjustment of either the inking mechanism or the ruling mechanism to which it belongs. The cone bearings of the ruling cylinders enable these cylinders to readily center themselves upon their supports, and the yielding support at one end of each cylinder permits the support to adjust itself to cylinders dilfering somewhat in length and also permits of ready removal and insertion of the cylinder. The adjusting screws by which the clamping plate is pressed against the wick being all attached to the sliding cover, thelatter can be removed together with the adjusting screws and clamplOO ing plate when access is required to the ink fountain. The contact of the ink ribbons with the ruling rings can be increased or diminished by adjusting the set screws upon which the inking frames rest and byinereasing or diminishing this contact the amount of ink which is supplied to the rings is correspondingly increased or diminished.
