PAPER-RULING MACHINE.

S2ECIFICA'IIGN forming part of Letters Patent No. 668,944, dated Febrhary 26; 1 901.

Application filed March 30, 1900. serial No. 10,865. (No model.)

To to who/7t it may concern.

Be it known that I, ROBERT WILMANS, a citizen of the United States, residing at Dallas, in the county of Dallas and State of Texas, have invented certain new and useful Improvements in Ruling-Machines, of which the following is a specification.

Myinvention relates to machines for ruling paper in which a series of pens are drawn across sheets of paper carried by a suitable support.

The object of myinvention is to provide a simple and efficient machine for this purpose and one which may be easily operated. I

In carrying out my invention I depart from the generally-accepted type of machine and provide a machine of a new type involving certain novel organizations of instrumentalities which insure the efficient performance of the operations incident to the process of ruling paper with lines of various kinds. The sheets of paper to be ruled are supported on an endless belt, which is given an intermittent movement to discharge ruled sheets, but which is stationary while the sheets are being ruled. The sheets of paper are fed to the belt while it is at rest and are guided and grasped at their rear-ends by guides and grippers, which hold the sheet while the pens are being drawn forward to perform the operation of ruling. While the carriage supporting the pens is being moved rearwardly toward the grippers and guides the belt is moved forward to discharge the ruled sheets. The pen-beams are pivoted in the carriage and are provided with independent strikerarms, which engage striker rails held in clamps of an improved construction so arranged that some of the rails may be removed or adjusted without disturbing the others. Improved devices are employed for holding the pens down to their work and for holding them elevated while not at work, and means are employed for causing the carrier-belt to move at the will of the attendant or automatically at fixed times. The grippers and guides are automatically withdrawn from the paper after it has been ruled, permitting it to be carried forward and discharged by the carrierbelt, and they are automatically moved during the rearward movement of the pen-carriage to bring them into position to guide the paper while being fed to the machine and afterwardil. 6., when the carriage begins to move forward-to grip the paper and hold it while the pens are in operation; The devices for operating the grippers and guides are adjustable, so as to cause them to operate at any desired time, and the feed-ta ble over which the paper is fed is also adjustable.

The general organization of the machine and details of construction will be hereinafter more fully explained.

In the accompanying drawings, Figure 1 is a perspective view of a paper-ruling machine embodying my improvements. Fig. 2 is a view, on an enlarged scale, showing a transverse section on the line 2 2 of Fig. 1. Fig. 3 shows a longitudinal central section through the machine. Fig. 4 is a View, on an enlarged scale, showing a top plan of a portion of the machine. Figs. 5, 6, and 7 show transverse sections of the striker-rails and their clamping devices. Fig. 8 is a perspective view of the guide and gripper. Fig. 9 is a view, on a reduced scale, showing the clamping-rails that hold the striker-rails in place.

The main frame of the machine may be of any suitable construction so long as it is adapted 'to support the working parts of the apparatus. Preferably there are four legs or standards a at each corner of the machine, on the upper end of which are secured two longitudinal beams B, and the frame may be stiffened by cross-pieces O at each end. Near each end of the machine is mounted in suitable bearings a roller D, over which extends an endless belt E, which may be made of cloth or other suitable material and which is preferably reinforced on one edge by a strip of leather 6 for a purpose hereinafter described.

Beneath the top of the belt E is arranged a table F, which may be secured at its opposite longitudinal edges to the side beams B. At the front or discharge end of the machine are mounted in suitable bearings a blottingroller G, of usual construction, and in front of and below the blotting-roller is arranged a discharge-board H. An inclined feed-table I is supported on the side beams B near the front end of the machine. The bottom rails I of the frame supporting the table I are preferably slotted, as shown at z, and through these slots extend bolts 1', having thumbnuts 2' By this means the table may be adjusted longitudinally of the machine to facilitate handling sheets of various sizes.

At the rear end of the machine I provide devices for guiding and gripping the sheets of paper. Ahorizontal rock-shaft J is mounted in suitable bearings secured to the rear ends of the side beams B, and on this shaft are clamped the combined guides and grippers K K. The guide K is somewhat longer than the others and is adapted to guide one side of the sheet. This guide K preferably consists of a long narrow strip of metal adapted to bear upon the top of the carrier-belt E, its rear end being provided with an enlarged base having a circular socket 10 adapted to embrace the shaft J and being split at k to allow the two jaws of the base to expand and contract to grip the shaft J or to loosen the base thereon. The two jaws of the base are connected by a screw-bolt having an adjusting-nut It. By this means the guide K, may be adjusted longitudinally on the shaft or laterally across the belt and. may be also turned axially on the shaft to the desired extent. Each of the combined guides and grippers K is preferably of the form shown in Fig. 8. It has a base 10 provided with acircular socket 70 adapted to embrace the shaft J and being split at k to allow the two jaws of the base to expand and contract ,to grip the shaft J or to loosen the base thereon. The two jaws of the base are connected by a screw-bolt having an adjusting-nut 70 By this means the combined guide and gripper may be adjusted longitudinally on the shaft or laterally across the belt and may also be turned axially on the shaft tothe desired extent. On the front upper end of each basepiece are two lugs 70 70 between which is arranged a circular nut 70. From the base of each combined guide and gripper K project forwardly two arms 70 70 The arm 10' is not made elastic, but is, in operation somewhat rigid and somewhat longer than the arm 70". The arm 70 at its rear end is circular in cross-section and screw-th eaded, as

shown. It projects through the nut 70 and throughunthreaded perforations in the lugs 10 10 The object of this arrangement is to permit the arm k to be adjusted longitudinally relatively to the arm W. The arm 10 is provided with a reduced portion 70 so as to allow the front end of the arm to yield at the proper time. The arm k is provided at its front end with a laterally-projecting arm 70 having a downwardly-projecting end piece 70 The front end of the arm 10 projects under the arm 10 within the end piece is", and it is adapted to have a slight vertical movement relatively to the arm k The extreme end of the arm 70 is preferably turned up at an inclination, as shown. The combined guides and grippers K are so constructed as to guide the paper while being fedinto position to be ruled and afterward to grip it andhold it securely while the pen-carriage is being moved forward to perform the operation of ruling.

A spring K secured to the main frame and to the shaft or to the base-piece it, tends to move the forward ends of the guides and grippers downward toward the top of the belt E. The shaft is operated to hold the guides and grippers upaway from the belt by mech anism hereinafter described.

The pen-carriage L preferably consists of .two longitudinal side pieces Z, connected at their rearends by a cross-piece Z and at their front ends by a cross-piece The side pieces Zrest upon and move longitudinally of the side beams B. Preferably one of the side piecesl rests upon a plain flat strip i secured to one of the beams B, while the other side piece'l is preferably formed with a longitudinaljgroove Z fitting aV-shaped rail Z secured to the other side beam B. The arrangement is such that the carriage may be moved back and forth in a straight line' toward and from the grippers and guides K K. The carriage supports a series of pen-carrying beams M, of usual construction, adapted to accommodate extension penholders or other such appliances. I have shown three pen carrying beams; but any desired number may be used. Eachof the pen-carrying beams is pivoted to thecarriage. At the ends of the beams I preferably employ headed screw-bolts m, suitablyconstructed at their inner ends to form a bearing for the ends of the pen-carrying beam, the arrangement being such that the screw-bolts may be withdrawn, if desired, to remove and replace the pen carrying beams, and the beams may be laterally adjusted when desired. Such bolts may, however, be used at one end only of the beams. The screw-bolts m extend through the longitudinal side piecesl and are provided with heads on their outer ends, by which means the screws may be withdrawn laterally from the beams and the beams may then be lifted outfrom the carriage.

Each pen-carrying beam has secured to it a'striker-arm N, which is L-shaped, extendingover the top of one of the side piecesZ and then downwardly in a diagonal direction toward the striker-rails O, hereinafter de scribed. Each striker-arm is provided with an adjustable weight n, by means of which the pressure of the pens on the paper may be varied.

' A rod P is arranged on top of one of the side pieces Z, beneath the upper or horizontal portions of the striker-arms, and it carries a series of upwardly-projectinglugsp,arranged in rear of the horizontal portions of the strikerarms. The rear end of the rod P extends through a guide-bracket p, and between this bracket and the next adjacent lug p is arranged a spiral springp which tends to move the bar P forward and to thus turn the strikerarms to a position to raise the pens from the paper or from the top of the belt E. The forward end of the rod P is provided with a lug ICC) 19 in front of which is arranged the end of an operatingaod Q. This rod extends horizontally across the carriage and is mounted in bearing-brackets q, secured to the rear cross-piece Z At one end the rod Q is provided with a crank-handle q, while the opposite end is provided with a crank the end of which is arranged in front of the lug p By means of the rod Q the rod P maybe pushed rearward against the pressure of the spring 19 so as to withdraw the lugs 19 from the striker-arms and permit the pens to lower and also permit the striker-arms to engage with the striker-rails and to be operated properly thereby.

It will be observed by an inspection of Fig.

2 that the pivots for the pen-carrying beams are arranged eccentrically, while the strikerarms are secured to the sides of the beams. Therefore when the diagonal portions of the striker-arms are moved up or down a pivotal movement is given to the pen-carrying beams, which will cause them to raise and lower the pens.

Depending from one side piecelof the carriage is a bracket or hanger R, which extends through an opening r in the table F, this opening being of sufficient length to permit the bracket to reciprocate back and forth with the carriage. To this bracket are pivoted two members of a clutch, so arranged as to grasp the carrier-belt during the rearward movement of the carriage, and thus cause the upper portion of the belt to move forward to convey the ruled sheet to the blotting-roller and to the discharge-board H. This clutch preferably consists ofalower memberS,which is of a segmental shape, pivoted at s to the lower portion of the bracket R havinga curved clutching-surface s and a segmental series of teeth 8 which engage a corresponding series of teeth 3 on the upper clutch member S. This upper clutch member is provided with a clutching-surface s and it is pi voted at s to the bracket E. This member of the clutch provided with a handle S projecting to the top of the machine within convenient reach of the attendant on one side of the machine. In order that this lever may be operated from the opposite side of the machine,l provide a lever-operating rod S ,Wl1l0h extends horizontally across the machine, being guided in guide-brackets s, secured to the rear cross-piece Z At one end the rod is provided with a handle 5'', while at its opposite end it is provided with a wedge-shaped portion 8 adapted to engage the handle and move it in such manner as to release the clutch. lVhen the carriage moves forward and while the pens are ruling the paper, the clutch does not grip the belt-,and consequently does not move it; but when the carriage moves rearward and the pens are elevated the clutch automatically grips the belt and causes the upper portion thereof to move forward. The carriage is moved back and forth by the attendant, who grasps one of the bandles M. The striker-arms N are, operated automatically by striker-rails 0. These tails are of proper shape and are so located as to hold one or more of the bars elevated to remove the pens from the paper or to permit the pens to drop into contact with the paper to accomplish the desired style of ruling. The lower ends of the striker-arms are preferably provided with lateral projections n to engage the upper surfaces of the striker-rails. The rails maybe arranged in pairs, as shown, side by side, and may, if desired, be made to overlap, as indicated at d; in Fig. 4. It will be readily understood that by properly locating and arranging the striker-rails the strikerarms may be operated in any desired manner to regulate the length and position of the lines.

The striker-rails are mounted in and held by clam ping-rails T T T Any desired number of clamping-rails may be employed, corresponding with the number of pen-beams used. The clamping-raiis are arranged in a holder V, preferably L-shaped in cross-section, as shown in Figs. 5, 6, and 7. The inner series of striker-rails may be arranged to rest against the vertical portion o of the holder, while the remaining series of strikerrails are clamped between the clamping-rails T T T These rails are provided on their upper portions with grooves or sockets t to receive the striker-rails.

By reference to Fig. 9 it will be seen that the inner clamping'rail T is provided with two holes i 6. The middle clamping-rail T is formed with a cut-away portion between the feet 25 and these feet are provided with holes 1? The third or outer clamping-rail '1 is provided with feet If, and these feet are each provided with a hole 25 Each clamping-rail T or T is provided with a series of feet. The drawings only show two on each rail; but the number of feet will depend upon the length of the rails. The rail T is secured to the vertical portion '0 of the holder by means of bolts W, which extend loosely through the holes 25 and enter screw-threaded sockets in the portion 1; of the holder. The rail T is secured to the rail T by means of bolts \V, which extend loosely through the holes 75 in the feet '6 of the rail T and enter the screw-threaded holes 15 in the rail T. The rail T is secured to the rail T by means of the bolts W which extend loosely through the holes #in the feet i and into the threaded holes t in the feet 25 of the rail T. The holes t for the bolts W are arranged in such manner that the heads of the bolts will be within the space between the inner ends of the feet 15 so that the heads of the bolts may be manipulated readilythat is to say, the feet 15 are arranged outside the bolt-holes t. The feet i are somewhat narrower than the feet 15 so that the bolt-holes 15 are not covered by the feet, and the heads of the bolts WV may be readily manipulated. By this arrangement the clamping-rails may be independently adj Listed-that is, they may be loosened and tightened independently. For instance, by manipulating the bolts (V the rail T may be moved relatively to the Vertical portion 1) of the holder, so as to either loosen or tighten the hold of the striker-rails held between the clamping-rail T and the vertical portion 12 of the holder, while the striker-rails held between the clamping-rails T and T and between the clamping-rails T and T are still held firmly clamped. In like manner by manipulating the screws W the striker-rails between the clamping-rails T andT may be loosened without loosening the others, and the same is true of the strikerrails held between the clamping-rails T and 'W-that is to say, the hold upon these rails may be loosened by manipulating the screws W without loosening the hold on the other striker-rails. Thus the several series of striker-rails may be removed or readjusted independently, and any set of striker-rails may be moved or adjusted without interfering with the other sets.

The paper guiding and gripping devices are operated automatically at proper times. The shaft K has secured to it an arm X, which extends downwardly from the shaft and is bent forwardly, its lower forward end being provided with an antifriction-roller 00. At times this roller rests on the enlarged end y of a shifter-bar Y. This bar is arranged horizontally, being supported at opposite ends in guides Y, secured to one of the side beams B and depending therefrom. The bar is formed with a series of holes y, in any one of which may be arranged a transverse peg g which, however, is always arranged in front of the lower end of the bracket R. To the bracket R, above lhe bar Y, is secured an arm Z, which is adapted to at times move under and lift the roller :13, and thus turn the shaft K. The spring K tends to move the shaft K in such position as to hold the guides and grippers K K down in engagement with the sheet of paper or with the top of the carrier-belt E. When the pen carrying carriage starts forward, the roller :10 is immediately removed from engagement with the arm z and lowers nearly to the top surface of the shifter-bar Y. When the carriage L has moved to near the end of its forward move ment, the lower end of the bracketR strikes against the peg y and thus moves the shifterbar Y forward, causing the enlargement y to engage and raise the roller 00, and thus turn the shaft K in such manner as to remove the guides and grippers K K away from the carrier-belt andto hold them in an elevated position fora time. While the pen-carrying carriage is being moved rearward, the guides and grippers are held elevated fora time; but near the extremity of the rearward movement of the carriage the arm Z abuts against the end of the enlargement 'y and moves the shifter-rail Y rearward, thus removing the enlargement y from beneath the roller 00 and causing this roller to ride upon the surface of the arm Z. This is so arranged that the guide K may be allowed to lower and rest upon the top of the belt E, and in like manner the ends of the guides k are allowed to come in contact with the top of the belt, while the ends of the gripper-arms 7c are held a short distance above the top of the belt. At this time a sheet of paper may be fed in and adjusted in the guides to the proper position. The armZisofjustsuflicient length to hold the guides and grippers in the position just described only while the pen-carrying carriage is at rest in its extreme rearward position. It withdraws and causes the lowering of the grippers immediately upon commencement of forward movement of the pen-carrying carriage. On the commencement of the forward movement of the pen-carrying carriage the roller 00 drops from the rear end of the arm Z, allowing the shaft K to turn a slight distance, so as to permit the gripper-arms k to lower and grasp the sheet of paper which has been adjusted in the guides. Then the carriage is moved forward and the sheet of paper is held securely while the ruling is being performed. After the sheet has been ruled and the carriage approaches the limit of its forward movement the bracket R strikes the peg y This causes the shifter-bar Y to be moved forward and the roller 00 is made to engage the enlargement y of the bar Y. This causes the gripper-sand guides K K to be elevated, so that during the next rearward movement of the carriage the clutch mechanism may grasp the under side of the belt and cause the upper portion of the belt to move forward to remove and discharge the ruled sheet. It will thus be seen that the attendant can operate the machine with facility and rapidity. He need only feed in the sheets of paper at proper times, release the pen-carrying beams, and move the pen-carrying carriage back and forth, the remaining operations being performed automatically by mechanism hereinbefore described. The pen-carrying beams may be nicely adjusted to apply the proper pressure, they may be quickly and readily removed and replaced when desired, and any of the striker-rails may be removed or adjusted with great facility without disturbing the others.

The carriage may be moved rearward, if desired, by springs or weights, as indicated.
