IMPROVEMENT IN PAPER-RULING MACHINES Specification forming part of Letters Patent No. 155,515, dated October 13, 1874; application filed September 3, 1874.

To all whom it may concern:

Be it known that I, JAMES TREGURTHA, Of

Boston, in'the county of Suffolk and State of mechanism of a paper-ruling machine which controls the action of the pens, and usually called the striker, and it consists, first, in

i the use of a wheel mounted upon an axis parallel to the axis of the string or driving-cylinder, and arranged to be driven by exterior contact with the periphery of Said cylinder, and provided with adjustable cam-blocks fitted to and secured in grooves formed inv the interior periphery of the rim of said wheel as a means of controlling the action of the pens, I

My invention further consists in the combination, with a cam-wheel constructed, arranged, and operated as above set forth, of a stop or lug secured thereto, a pawl-lever arranged to be interposed in. the path of said lug, and a latch-lever to lock said pawl-lcver in position, and suitable devices for tripping said latchlever to release said wheel, and allow it to revolve at the proper time.

My invention further consists in the use, in combination with a wheel provided with adjustable cam-segments, of a cam-lever made in two parts, and secured together by means of an axial clamping-pin, so as to form a rigid lever, one portion of which may, by loosening said axial pin, be swung to one side in a plane at right angles to the plane of movements of said lever, when acted upon by the cam, to facilitate the removal of the cam-wheel, and the substitution of another of different size, which becomes necessary as oftenas the size of the paper to be ruled is changed.

the pen-beam is vibrated to lift the pens from the paper at the proper time.

My invention further consists in attaching the pen-beam lever to said beam in such. a manner that it may be adjusted about the axis thereof for the purpose of adjusting the lift of the pens; and it further consists in constructing said lever with a broad pad or table-like surface at its outer end, to receive the end of the set-screw in the end of the camlever, so as to allow of any desired amount of adjustment of the end of the pen-beam Without breaking the connection between the two levers.

My invention further consists in the appli cation of a similar pad or table to the outer or movable end of the lever, which operates the rocker-shaft, through which the latch-lever is depressed to release the stop-pawl, and allow the cam-wheel to revolve. Upon this pad rests the end of a set-screw attached to the movable end of a lever, firmly secured to .a rocker-shaft above the pen-beam, from the opposite side of which projects another lever or arm, to the movable end of which is\sccured, upon a suitable axial pin, the ordinary trip-wheel forreleasingthe cam-wheel.

My invention further consists in giving to the trip-wheel more lift than is required to release the cam-wheel, and varying the time of such release by interposing between the trip-wheel and the latch-lever that locks the cam -wheel an adjustable point of contact in the shape of the set-screw last referred to.

My invention further consists in fitting said screw in a nut pivoted to the end of the rocker-shaft arm, so as to swivel therein, the axis of said nut being at right angles to the axis of the screw, in combination with a fixed guide, through which the lower end of said screw passes, said screw being raised or lowered to vary the time of the pens striking the paper.

In the drawings, Figure 1 is a plan of so much of a paper-ruling machine as is necessary to illustrate my improvements. Fig. 2- is a vertical transverse section on line w w on Figs. 1 and 3. Fig. 3 is a side elevation of the lustrating the construction of' the cam-lever and its relation to the pen-beam lever, as well 7 is a plan of a portion of the train of mechan-' ism for operating the latch-lever to release the cam-wheel. l

A A is the frame of the machine; "B, the cloth or apron cylinder; 0, the pen-bearing cylinder; and D, the apron-roll, mounted in bearings, made adjustable by means 'of the 3 screw-nuts a a, all constructed and arranged in a well-known manner. E is the paper-carrying cloth or endless apron. .F is the stringcylinder, mounted upon the driving-shaft F. G and G are the stringguide rolls, around which and the cylinder F are led the endlessstring belts b b, in the usual manner. 'H is a disk-wheel, mounted upon a stud, 0, set in the movable end of the radius-arm I, arranged to vibrate about its fulcrum-pin, to adapt its position to the size of the cam-wheel being used. The wheel H must have an exterior circumference about equal to the length of the piece of paper to be ruled, and is provided with a heavy projecting rim, H, upon one side, in the inner face of which are formed two grooves, d and d, of unequal depths, in which may bein- 'serted one or more segmental pieces of metal, '6 0, so formed as to project beyond the inner periphery of the rim H a distance equal to the movement that it is desirable to impart to the cam-truck for lifting the pens from the paper. These segments are held in position by the setscrews f and f, the screw f bearing against the segment in the groove d, and f against the segment in the groove (1 said screw passing through solid metal below the bottom of the groove d and the segment contained therein, as seen in Fig. 2. The wheel H rests upon the periphery of the string-cylinder F, and is forced against it by the spring J or a weight with sufficient force to cause it to be revolved thereby when not prevented by the stop. K K is a cam -lever, made in two parts, connected together by the axial clamping-boltg, so as to form a rigid lever, and mounted upon the fulcrum-pin h, set in the stand L in a horizontal position, parallel to the axes of the wheel H and the string-cylinder F, and at right angles to the axial pin g, which secures the two parts K and K of said lever together. The mov-, able end of the part K'of said lever is provided with a stud, i, set rigidly therein, and projecting therefrom parallel to the fulcrumpin it, and upon which is mounted the camtruck j, arranged to rest upon the inner periphery of the rim H of the wheel H, or the "segments 6 e set therein, said truck being located between the axis of thewheel andthe point of contact of said wheelwith the periph cry of the string-cylinder. The opposite mov- "able end of the lever K K is provided with pens to the work.

of the pen-beam M. The lever l is mounted loosely upon the threaded journal'shaft m, and may be adjusted about said journal and secured in any desired position by the screw n andnut '5, fittedt-o and moving in the slot p formed in the plate q, secured permanently to the end of the pen-beam M, as seen in Fig. 4. The pen-beam Mis made in two parts, secured together by the screws W, and has permanently attached to one end thereof the smooth journal-shaft s, and to the other end the plate q, in which is journaled so as to revolve therein the threaded journal-shaft m, said shaft being so fitted to the plate q that, while it may revolve therein, it cannot be moved endwise therein. N and N are two stands, in which the penbeam M is mounted by means of the journalshafts m and s, the stand N being provided with a female screw-thread to fit the thread on the journal on, so that,by revolving the journal-shaft m, by means of the milled headv t attached to its outer end, the pen-beam M may be moved endwise to adjust the pens laterally upon the paper being ruled. The stand N is secured to the top of the frame A by the screw u, and the stand N is secured to the plate 0 by means of the thumb-nut P and a headed bolt passing through a slot in said plate, with the head below the plate, in a well-known manner, so that said stand may be adjusted in the direction of the length of the machine, for the purpose of squaring the Q is a rocker-shaft, mounted in hearings in the upper part of the stands N and N, directly over the pen-beam M; and It and R are levers firmly secured thereto, and projecting from opposite sides thereof, as shown. The lever B is provided with a stud, 11, upon which is mounted the trip-wheclS, having a portion of one side cut away, so as to fit or nearly fit the curve of the pen-bearing cylinder, upon which it rests, with the endless apron E interposed between, and provided with the small projecting tooth o, against which the sheet of paper strikes 'as it is carried forward by the endless apron E and string-bands b b, and by the continued forwardmotion of thepape'r said wheel is revolved, which raises the lever B, rocks the shaft Q, and depresses the outer end of the lever B.

The'lever R has pivoted to the side of its outer end the nut 10, through which passes the screw w, and in which it may be adjusted to vary the 'distaucebetween its lower end and the lever a rigidly secured to the rocker-shaft 12*, upon which it strikes when the lever B is depressed. y I

This adjustment is of great advantage, as

admitting of a much finer adjustment of the the'guide a projecting from the stand N, and? the swiveling attachment of the nut w allows a free movement of the lever B through the:

arc of a circle without causing the screw w to bind in its nut. The movable end of the lever a 'is expanded into the form of a broad, pad, upon'which the end of. the screw w .will' strike when it descends, into whatever-position the pen-beam may beadjusted; and said lever is held up, when the, pressure is removed, by the spring a. m M v r 1 \r The rocker-shaft b is mounted in bearings, in the stands 0 0 secured to the plate 0, and has secured to its end, opposite the lever a another lever, (1 projecting therefrom, upon the same side as a the movable end of which rests upon one end of the latch-lever 6 provided with the shoulder 0 and pivoted at c to the stand f as seen in Fig. 6.

g is a stop-pawl, pivoted to the stand it, the long arm of whichdepeuds from its fulcrum-pin, and rests upon the latch-lever 0 just forward ofthe shoulder 0 while its short arm is maintained in a position to be struck by the dog orlug 11 secured to the face of the rim H of the wheel H, as seen in Figs. 3 and 6.

The lever e is provided with a counterpoise-arm, 0 which causes the latch to operate by the force of gravity, and the same force causes the stop-pawl g to assume a position to be latched after it has been tripped.

T T are gear-wheels, by which motion is imparted from the driving-cylinder to the cloth or apron cylinder; and U is a crank, by which the machine is operated.

A great advantage is gained by the use of my improved cam-wheel, arranged as set forth, from the fact that any desired diameter of cam-wheel may be used without change in, or adjustment of, other parts of the mechanism, the cam-truck j on the end of the lever K'alwa sfbearing the same relation to the point of contact of the wheel H with the string-cylinder; and, if the rim H of all the cam-wheels is made of the same radial width,

it follows that a wheel of any desired diameter may be' substituted for the one in use without changein other parts of the mechanism, except to, swing the radius-arm I into the proper position to bring the lower edge of the cam-wheel into contact with the periphery of the string-cylinder F, as described.

The peculiar construction of the lever K K is for the purpose of facilitating the changing of the cam-wheels, which is done by loosening the axial bolt 9 and swinging the arm K with the truck j away from the cam-wheel H, when the camwheel, together with its supporting-arm -1, may be raised, it necessary, and the wheel H be withdrawn from its stud, and another wheel of difl'erent diameter put in its place, when the arm K is again swung into position parallel to the face of the cam-wheel, with the truck j above the rimjH, and the axial clamping-bolt is screwed down hard,-'when the machine is again ready for operation.
