SPECIFICATION forming part of Letters PatentNo. 714,576, dated November 25, 1902.

. Application filed July 21, 1902.?

To all whom it may concern.-

Be it known that I, ELLIS GRABER,machineruler and machinist, a subject of the King of Great Britain, residing at 33 Ohandos road,

Tunbridge Wells, in the county of Kent, England, have invented a new and useful Improvement in Ruling-Machines, (for which I have filed an application for Letters Patent in the United Kingdom of Great Britain and [0 Ireland, numbered 26,362, and hearing date the 24th day of December, 1901,) of which the following is a full and complete specification.

This invention relates tohruling-machines in which the sheets of paper to be ruled are passed under the ruling-pens by means of a traveling endless apron; and it has for its objects, first, to arrange the traveling end less aprons so that they cannot possibly become marked by the ruling-pens when sheets of paper are not passing beneath the pens,

second, to increase the length of drying-surface without increasing the length of the machine; third, to provide for ruling both sides of the sheets of paper; fourth, to provide for bringing the sheets of paper squarely up to the ruling-pens; fifth, to provide for the traveling endless aprons running truly and square with the ruling-pens; sixth, to provide for altering and adjusting the positions of the pen-beams, and, seventh, to provide for the pens being automatically broughtinto line as they are secured to the beam, and, lastly, to produce ruled work with a less cost and in a more expeditious manner than has 5 heretofore been practicable. I attain these objects by the mechanism illustrated in the accompanying drawings, in which- Figure 1, Sheet No. l, is a View in side elevation showing the general construction and 40 arrangement. Fig. 2, Sheet No. 2, is a diagrammatic view showing the arrangement of one of the endless traveling aprons and its threads. Fig. 3, Sheet No. 3, is a diagram matic view showing the arrangement of the 5 other endless traveling apron and its threads. Figset and 5,Sheet No. 4, are broken views, in

partlyin section, of part of the machine. Figs. 6 and 7, Sheet No. 6, are broken views,

in side elevation and plan, respectively, showing the device for bringing the sheets of paper squarely up to the ruling-pens for the second ruling. Figs. 8 and 9, Sheet No. 7, are broken views in side elevation and plan, respectively, showing my improved lay-boy.

In my improved machine both sides of the paper can be ruled at one turn through the machine. Also two operators can feed simultaneously either on two distinct jobs or on the same job, thereby doing the Work of two double machines; For instance, one. opera- 6 tor can feed the paper for feint lining and the other for down or cross lining at the same time, so that once the machine is prepared and set running the work is at once produced. ready for binding, packing, &c.

A machine constructed according to the present invention has the advantage that without increasing the length of the machine the travel available for drying the ink has i It also dispenses with most of the overhead gear, whereby better light on the work is obtained, and, moreover, as

both pen-beams are arranged on the same level the usual height of a single machine is not increased, thereby doing away with the so-called two-deckers. As about one-half of the top of the machine is available for piling paper on, there is a considerable economy in space.

The frame a carries two distinct ruling apparatus, each of which consists of a pen-beam,

an inking device, a traveling apron, and traveling threads to keep the sheets of paper in contact with the aprons, while common to both such apparatus is the driving mechano ism, the cam mechanism for operating the inking device, the feeding-table, the lay-boy, and the delivery-table.

The two traveling aprons Z) and c are arranged as shown in Figs. 2 and Referring 5 to Fig. 2, the apron b, which is endless, lies over two horizontally-arranged rollers b and b at the front end of the machine. It then passes around another small roller b located below the roller b and then up over a large 10o roller b the periphery of which is on a line with the two rollers b and biwhereby a loop or .mediate guide-roller b to a similar roller 6 at the back end of the machine, around the said roller, and forward again over an intermediate guide-roller b to another roller 12 atthe roller 1).

front end of the machine immediately above the roller b From this roller the apron passes up over another. guide-roller b to the The threads at for the apron b are arranged as shown in dotted lines in Fig. 2, being guided by suitable guide-rollers d d, &c. The other endless apron c is arranged as shown in Fig. 3. After passing over rollers c, 0 c and 0 arranged in a similar manner to the rollers 19', b b and b to'give a loop or dip to it the apron passes to a roller 0 at the top rear end of the machine, around this roller, and over a suitable guide-roller c to a roller 0 located as near to the front of the machine as the first apron b will allow, thence back for a distance about half the length of the machine, around a roller 0 and forward again over the roller 2) of the first apron, thence over the guide-roller b also of the first apron I), located under the roller 6, around guide-rollers c to the rollersc. The threads e for the apron c are arranged as shown in dotted lines in Fig. 3, being guided by suitable guide-rollers e e, 850.

Between the two aprons b and c are endless threads lc. (Shown in dot-dot and dash lines in Figs. 2 and 3.) These not only serve to conduct the sheets of paper from the apron b to the apron 0, but are specially arranged, as will hereinafter be more particularly described, to square the sheets of paper up before delivering them onto the apron c.

The rollers 17 and 0 by means of which the loops or dips are formed in the endless aprons or sheets I) and-c, are each mounted in adjustable bearings a, so as to provide a means of adjusting the tension of the said aprons.

In order to obviate any undue strain on the endless aprons and also to insure the various mechanisms acting synchronously, the axles carrying the rollers b b b 0 c and c are geared positively together by means of chains and sprocket -wheels, as illustrated diagrammatically on Figs. 2 and 3. Y An endless sprocket-chain 03, arranged on one-side of the machine, gears with the under side of a sprocket-pinion 'y, fixed at the rear end of the machine on a counter-shaft y, geared with the main shaft zby any suitable form of variable gearing z. The chain x then passes upward and gears with the upper teeth on a sprocket-wheel J0, fixed on the axle carrying the roller b'fithencepasses to the front end of the machine around an idle sprocket-wheel 00 carried on the axle of the roller b then around sprocket-Wheels x x and 00 fixed, respectively, on the axles of the rollers 0 b and b returning to the pinion y after first gearing with the upper teeth on a pinion 'u, fixed on a. counter-shaft 'v. A second endless chain 00 arranged on the opposite side of the machine,after gearing with the under side of another sprocket-wheel, fixed on the opposite side of the countershaft 2;, passes upward over sprocket-wheels m a fixed, respectively, on the axles of the rollers c and c and returns to the sprocketwheel on the counter-shaft 1) after passing over an idle guide-pulley 00 and gearing with a sprocket-wheel 00 carried by the operating-shaft 0 of the lay-boys.

The direction of travel of the chains and the direction of rotation imparted to the rollers are as shown by arrows on the drawings.

In each loop or dip is placed a transverselyarranged plate Z, having one or more longitudinally-arranged grooves Z in it, over which the ruling is effected. This plate is arranged on a level with or slightly above the rollers b b and 0 0 respectively, and also with the feed-table.

The heads carrying the pen-beams and inking devices are so mount-ed with respect to the loops or dips in the endless aprons that the pens carried by each bear on or lie over the grooved plate Z, located in the said loop or dip. This grooved plate is pivoted at the center on a cross-bar Z and at each end are slots to enable it to be adjusted at an angle with the traveling apron. The operative points of the ruling-pens lie over the longitudinally-arranged groove or grooves Z in this plate, and as the loop or dip in the endless apron is immediately under this grooved plate the pens can never touch the apron even if no sheets of paper are passing, so that they can be kept down over the groove or grooves, and the machine can run continuously with out fear of the endless apron being marked by the ruling-pens when the sheets of paper are not passing beneath them. Thus it will be seen if the operators are not sufficiently competent to feed the paper at the high speed the machine is capable of traveling, owing to the special method of doubling the length of drying travel-say, for instance, when two operators are working at the same time on i one or two jobs and the operator stops or finishes his job before the other-no material harm is done to anything, which is a great advantage when the machine is being operated by unskilled persons.

The endless strings d and e employed to keep the sheets of paper in contact with the traveling aprons run on suitable guide-rollers d d, &c., and e e, &c., and are automatically kept at a constant tension by weighted pulleys d and 6 located at the rear end of the machine.

The pen-beam f instead of being pivoted in bearings mounted on the frame of the machine is pivoted on a transverse barf, fixed to pillars f adj ustably mounted on the sides of the frame a of the machine, so that the said beam can be readily and conveniently lined up with the frame without any risk of binding the bearings. The lower part g of the pen-slide is extended beyond the upper part and has a raisededge g, with which the pens g engage at a convenient distance from their operative ends, which tends to automatically bring and keep them in line, as they are clamped in the slide.

The striking-gear for stop-rulin g operating by lifting the pen-beam comprises a lever f carried by the pen-beam f. The position of the lever f with respect to the pen-beam can be varied and adjusted by hinging the lever f to the pen-beam and controlling the movement by set-screwsf f A set-screwf carried by the lever f and engaging a stop f carried by the frame, is also provided for adjustment purposes. The free end of the lever f is furnished with a rubbing-piece f adapted to contact with removable and adjustable cam-piecesf carried on the wheel f fixed on the axle h of the roller 29 It will be understood and seen on reference to Fig. 1 a separate striking-gear, arranged precisely as above described, only operated from a cam-wheel fixed on the axle h of the roller 0 is provided for the second ruling mechanism.

The axles h, carrying the cams which operate the striking and stop-gate gears, are geared together by means of sprocket wheels and chains, as hereinbefore described, so that the said cams act synchronously, which is a matter of importance when the machine is ruling paper on both sides during one travel through the machine.

The inking of the pens can be done in the usual way, but preferably by the device described in the prior patent, No. 609,884, dated August 30, 1898. The cam m, by which the controlling device is operated, is mounted on an axle m, carried in bearings formed or fixed to one end of a rocking arm n, mounted to rock freely on the axle h. The axle m is geared to the axle h by means of a spurwheel m and pinion 71 The rocking arm n is connected with the starting-lever U by meansof an eccentric u, whereby the movement of the starting-lever u to stop the machine drops the axle m, carrying the cam m, so that it will not engage the controlling device, thereby insuring, should the machine be stopped when the cam m is in engagement with the ink-controlling device, that the fiow of ink is stopped. The ink-controlling device for both the pen-beams is operated from the cam m by means of two levers 0% m pivoted to the frame at m and m, respectively,

the one end of the lever m or a roller thereon being operated directly by the cam m, its free end engaging the one end of the other lever m Whose free end is connected to the ink-controlling device of the other pen-beam. Instead of having a plurality of rubber tubes for each colored ink delivering the ink from the reservoir and nipped by the nipping-bars of the ink-controlling device, as described in the aforesaid prior patent, a single rubber tube t for each colored ink is used. The tube t delivers the ink to a pipe or trough t, arranged over and parallel with the pen-beam, and the ink from said pipe or trough is dis tributed to the required position for the pens by a series of taps or cocks t carried by said pipe or trough t. The stop-gates s, in combination with the striking-gear for stop-ruling, are opened instantaneously by means of cams j, carried by wheels on the axles h of the rollers b and 0 respectively. Levers s, pivoted at s to the frame, each have their one end adapted to engage their respective cam, while their free ends are connected by links .9 with arms 3 fixed on axles 3 carried by the frame and furnished with oppositely projecting arms 8 carrying the gates 8. Provision is made for readily throwing the gates out of gear, which may be conveniently accomplished by simply turning the arms carrying the gates into a 'Vertical position, thereby preventing the levers contacting with their cams.

Eccentrically-mounted rollers s are provided adjacent to the stop-gates and over which the endless aprons and threads pass, whereby the aprons and threads at such points may be slightly raised on rotating the rollers s in the necessary direction, thereby providing for fine adjustment, so as to enable the gates to stop paper as fine as tissue without rucking or wrinkling its edge. Hand-wheels s fixed to the axles of said rollers 3 are provided to facilitate adjustment of the same, and lock-screws 3 working in slots formed in said wheels, are furnished to lock the rollers in position after the adjustment has been effected.

The feedingtable 1) is mounted. between the two beams, so that the two parts of the machine can be fed from the same table, the sheets of paper being fed from each side, the operators standing opposite each other. This table is provided with guides 19 p at each side, which are capable of being set transversely within certain predetermined limits to provide for any inaccuracy in the cutting of the sheets of paper. In addition to the side guides p there is also fixed a pair of central guides p transversely adjustable, so that the sheets of paper can be guided by both edges. These central adjustable guides are preferably fixed by a central clamping-bolt or traversing a transverse slot in the board and by a clamp at the front edge; but any other suitable device may be employed. On this feeding-board a stack of sheets of paper is laid in between the guides and simply stroked in between the threads d and the apron 19 passing over roller 1), and by its use a greater output and speed are obtained, owing to the minimum amount of handling the paper receives, and it also saves damaging the paper. Provision is made for the table, with its guides,to be raised for the purpose of inspecting andoiling the interior of the machine by hinging the table at p to the frame a and providing handles 19 on said table.

The endless threads la, (see particularly Figs. 6 and 7,) which receive the sheets of paper from the apron b and deliver them to the apron c and threads 6, are carried on grooved rollers k and k The roller k is formed in two parts capable of longitudinal movement on the axle k Set-screws k are provided on each part in order to lock the said parts to the axle after the required adjustment has been made. The object of this adjustment is to suit the different sizes of paper passing through the machine. The axle is driven by gearing from the roller 0 or from any other convenient rotating part in such manner that the threads 70 will travel at a slightly-greater speed than the threads d e and the apronsb c in order that the sheets of paper may be slightly separated from each other while traveling on the threads 70 to enable the said sheets to be properly squared up be fore passing under the second set of rulingpens. This squaring up is effected by so setting or adjusting the roller 70 that the threads is incline outward to each side of the machine, as shown, a greater inclination being given for large'sheets of paper than small ones, so as to cause the one edge of the sheets of paper traveling thereon to engage the parallel guides a fixed on the frame a. It is to be understood that the arrangement shown and described is for squaring up two sheets of paper simultaneously, one sheet on each side of the machine. Each sheet must of course only be of such a size as to be carried by the threads inclining in one direction. When it is required to square up a sheet of paper of a greater size, the roller 70 must be so adjusted as to cause all the threads to incline in the same direction. It will thus be seen that the sheets of paper are automatically squared up before being delivered to the apron c for the second ruling.

Lay-boys 0 o are arranged at the rear end of the machine between the two traveling aprons b and 0 and differ only from the ordinary construction, inasmuch as their feeding-rollers o, 0 0 and 0 are geared up by the sprocket-wheel 00 so as to deliver the sheets at longer intervals than they are received by them, and the inner side guides are made adjustable to suit different widths of sheets.

The side guides 0 0 are carried by the feed-rollers 0 0. The former, together with the feed-rollers 0 are capable of being clamped to a fixed transverse bar 0 The feed-rollers 0 arranged beneath the rollers 0 are so mounted on the shaft 0 as to be free to slide thereon and also to rotate therewith. The rollers 0 are kept in gear with the rollers 0 by forming grooved collars on the former, adapted to be engaged by projections carried by the guides 0 The delivery-table r is provided with adjustable transverse fixed stops 1' and longitudinal fixed stops 'r The latter are preferably carried by the movable guides 0 of the lay-boys, so as to make the one adjustment serve two purposes and also economize space.

The stops r r are given a reciprocating motion, so as to knock up each sheet square as it is delivered on the table. The stop r is reciprocated directly by means of eccentrics r mounted on the shaft 0 communicating motion to shafts r carrying the stop W. The stops r are also reciprocated from the motion derived from the shafts r through the medium of links and bell-crank lever r". The stops 7' are so formed or hinged as to enable them to be turned down in order to facilitate the removal of the ruled sheets from the table.

A table g, on the rear part of the machine, is provided whereon the ruled paper after removal from the table r is stacked. A rack q is also provided between the supports a of the thread-carrying guide-rollers 01 e, adapted to hold a series of pen beams when not in use;

The starting and stopping of the machine can be effected from either side by means of levers it, connected to a shaft M, which carries the eccentric it, hereinbefore referred to. The shaft to is connected in any suitable manner with a belt-shifting fork acting on the main driving belt, engaging pulleys on the main shaft 2'. The eccentric u, not only operates the arm n of the ink-controlling device, but also looks the shaft a in its position, thus locking the belt-shifting fork on the fast or loose pulley, and so preventing the machine from starting accidentally.

In operation the action is as follows: The sheets of paper are laid on the feeding-table p between the guides p p and are stroked in one by one from a pile between the threads 61 and the apron b, and, passing over the roller 1), they are nipped by the endless threads running around the said roller and carried under afeed-roller b. As soon as the edge of the sheet of paper passes over the groove in the transverse plate the pens yield onto the surface of the sheet of paper, and by the travel of the sheet it becomes ruled. Thus the first side is done. From thence the sheet is carried on by the guide-rollers and endless strings or threads around the various pulleys supporting and guiding the apron b for drying the ink. The sheet of paper is then delivered (by this time the ruled side is face downward) onto the threads is, and is thereby automatically squared before it passes onto the second apron c and between it and the threads 6 under the feed-roller c and the second set of pens for ruling the other side. The drying is repeated by the travel around the various pulleys supporting and guiding the apron c. The sheet is then automatically delivered by the lay-boy perfectly dry and square onto the delivery-table.
