RULING-MACHINE.

SPECIFICATION formingpart of Letters Patent N 0. 674,434, dated May 21, 1 901.

Application filed October 30, 1899. Serial No. 735,200- (No model.)

To a whom, it may concern:

Be it known that I, CHARLES BURROWS, a citizen of the United States, and a resident of the city and county of Schenectady, in the State of New York, have invented certain new and useful Improvements in Ruling-Machines, of which the following is a specification.

My invention relates to improvements in ruling-machines shown and described in Letters Patent Nos. 568,235 and 568,236, dated September22,1896; and it consists in the devices and parts and combinations of devices and elements hereinafter described, and set forth in the claims.

The objects of myinvention are to provide in a ruling-machine and in combination with a pen-beam provided with ruling devices and adapted to be raised and lowered at pleasure of an operator for convenience of adjusting the said ruling devices a vertically-moving bed which is automatically operated for carrying sheets of-paper to the pen or pens of the machine and withdraw the same therefrom at times and intervals as may be required by the character and kind of ruling to be given to the sheets, and also to provide mechanism by which the sheet-supporting bed may be automatically raised, so as to carry a sheet to be ruled up to the pens, and there be held for a proper time and then be automatically lowered for carrying the sheet out of contact with the said pens or inking-rollers and be so held for such a time as may be required before being moved up toward the pens for receiving ink therefrom when the ruling is to be resumed, and, further, to remedy the defects arising from a trembling of the pens or slight movements of the points of the same, which to a degree attended the same when dropped down on the paper as heretofore when operated by the pen-beam and dropping from a raised position to the paper and checked as heretofore, so as to give to the pen-beam a shock which generally caused a quivering of the pens.

Other objects and advantages of this invention will be fully understood from the follow--' ing description and claims when taken in connection with the annexed drawings, in which- Figure l is a side elevation of a ruling-machine embodying my improvements with so much of said machine and parts and devices thereof as is necessary to show the connection of the cooperating parts and devices with the improvements in this invention. Fig. 2 is a plan view of the same.

Similar letters of reference refer to similar parts throughout both views.

In the drawings, A is the drive-shaft of the machine. A is a feed-roller mounted on said shaft, and ais the usual endless cloth carried by suitable rollers for carrying the sheets to be ruled. O is a revolving disk secured on shaft 0 and carrying movable cams O and G which are adjustable at will on the peripheral portion of said disk. The mechanisms for gearing these above-mentioned parts together so that the said revolving disk and its adjustable cams may be properly revolved by the said drive-shaft are fully shown and described in my Letters Patent No. 568,235, above mentioned, and therefore unnecessary to be shown and described in this specification.

B is the pen-beam, arranged across the machine and supported from each end from the side rails of the frame of the machine by standards D, (one of which is shown in the drawings) which are adjustable and are fully shown and described in my Letters Patent No. 568,236, above mentioned, and therefore unnecessary to be more particularly described. This pen-beam B is supported from standards D by means of a horizontal pintle (1, provided at each end of the said beam and working, respectively, in a suitable bearingpiece d, secured therewith with one of said pintles as shown in Fig. 2, provided with screw-threads (1 working in a screw-threaded split nut D, provided with tightening-screw d and having a horizontal arm cl working in sleeve D which is longitudinally split and tightened by screw d and is provided with vertical stem D which is adjustable at will in said standard D. This pen-beam is also provided at one end with arm B, which is pivoted by pivot 12 on the upper side of said pen-beam and is adapted to be variously adjusted in vertical direction by means of screws b 12 so that its free end I) may be depressed or elevated in relation to a suitable stationary toward and to the pens b and downwardly.

and away from said pens at times and intervals as the character and kind of ruling of sheets of paper may require, and'any suit able mechanism arranged between said vertically-moving bed E and the revolving disk 0 and adapted to be operated by cams C and C may be employed for moving said bed toward the pens b and holding the sheets supported thereon in contact with the said pens and for effecting a lowering of said bed. that the sheets may be carried out of contact with the same. This vertically-moving bed E may be of any suitable material, as of metal or wood, or both combined, as may be preferred, and be made with any suitable length and width to adapt it for service in the machine for supporting sheets of sizes to be ruled. It is supported from the side rails of the frame of the machine o'rany stationary piece secured thereto by arms F, one at each end of the bed. Only one of these arms is shown in the drawings, as each arm is a duplicate of the other and a description of one will suflice for the other. The forward end portionf of the arm F is secured, by means of bolts or screws 6 e, to the said bed, preferably by being applied to the end of the same, and its rear end portion f is pivoted to the side rails D (one of said rails only is shown) by a suitable pivot F. The forward end of each said arm is provided with an outwardly-projected horizontal flange F preferably integral with portionfof said arin, as shown in Fig. '2.

G is a editable rock-shaft extending from one side of the machine to the other and supported from the end journals in suitable bearings G, (one only shown,) provided with the.siderai ls D, to which they are secured from their upper sides. With these hearings G are provided a lug g,having a screw-threaded hole 9', (indicated by dotted lines in Fig. 1,) which receives the adj ustingscrew Gr (shown in Fig. 1) to be provided with jamnu'tg Rigidly secured to each end of the rockshaft G, at near the forward end of the bedsupporting arms F and beneath the flange F are arms H, integral with suitable hubs h, which arms are each a duplicate of the other and of which one arm H only is shown by full lines in Fig. 1 and indicated by full and dotted lines in Fig. 2. Secured to the rocks'haft G at a point opposite the periphery of the revolving disk 0 is the pendent arm J, integral with hubj, by which it is secured to shaft G. The lower end of this pendent arm is preferably provided with friction-roller J,

which is about opposite said periphery. Secured to the same end of rock-shaft G and adjoining the pendent arm J is the gage-arm K and keeper-arm L, both of which are preferably integral with hub it, by which they are secured to the rock -shaft. 'These several arms H, J, K, and L are so secured to the rock-shaft G that they may move with the same and also so that when either one of the same is moved by its operating mechanism provided the other arms will be correspondingly moved, as will be hereinafter described.

Secured to the side rail D and in part opposite the revolving disk 0 is the latch-frame M, provided with latch N, pivoted to the former and having at its rear side a reacting spring M, (indicated by dotted lines in Fig. 1,) all similar to the latch and frame and reacting spring shown and described in my Patent No. 568,285 before'mentioued. N is provided on its outer side with the inclined project-ion P, which is situated in the length of the latch, so as to be in the line of the circle in which the latch-operating cam 0 (shown in the drawings) is carried by the revolving'disk O. This latch is also provided with stop Q. (Shown by full lines in Fig. l and indicated by dotted lines in Fig. 2.) When in the revolution of disk 0 the cam C is carried inwardly in direction from the inner side of said disk, the keeper-arm L will by the weight of the vertical moving bed E and its pivoted arms F, imposed on arms H, move said am L'to the front of Stop@ at the instant the "latch N is moved inward by the act-ion ol cam C on the projection P, and arms H will be lowered and gage-arm K will be raised to dotted lines and strike against the lower end or the adjustin-gscr'ew G which limits the drop of the said arms H, and consequently that of the bed E, from the penis I), and so long as the keeper-arm L is in front of the said step Q the said bed will be down and out of contact with said ruling devices and all the said arms will be'in position of dotted lines, indicating their changed positions. When in the revolution of the revolving'disk G the adjustable cam 0 which is shown in Fig. l to be projected beyond the periphery of said disk, is carried'against frictio'n-roller J ,pivotedonthe pendent arm J ,said arm J will be moved back from dotted lines in Fig. 1 to that of full lines and so turn the rock-shaft that it will carry the gage-arm K to full lines and away from the adjusting screw and arms H upwardly, so as to move the bed E u p, so as to carry the paper thereon intocontact with the pens b, which latter is so well known as not to require any particular description. When said arms J, K, and H have been so moved to full lines, the keeperarin L'will have been moved from position in front of stop Q and from pressing in said latch thro'ugh's'aid step Q, and its front side edge will be brought to the rear side of said stopjwhen the reacting spring M will push This latch the latch forward and carry said stop Q in engagement with said keeper-arm L, and thereby lock the rock-shaft from moving and the paper-supporting bed in raised position, as shown.

The drawings show by full and dotted lines two similar adjustable cams C and two similar adjustable cams C secured to the rim of disk 0, the former for operating with the inclined projection on the latch N and the latter for actuating arm L on the rock-shaft. These cams C C may be each used in number of one or more, as may be required, and may be variously set and adjusted at pleasure on the rim of the disk as may be necessary as the ruled ink-lines to be produced on the paper supported on the bed may require for length, continuity, beginning, and stopping of the same.

The gate for regulating the feed of sheets of paper and tapes for carrying the same beneath the ink-ruling pens or rollers and other devices employed in rulingmachines are omitted from the drawings and this description, as they do not form any part of this invention, and these devices and mechanisms in my preferred form are clearly shown and described in my patents above mentioned and therefore do not require any further description. It is to be understood that the movable bed-piece may be variously changed or modified in its form of construction and proportions and that it may have its rearward portion supported in various ways Without changing or aifecting its operation or that of parts and devices employed with said bed in this invention.

My above-described improvements operate to allow the ruling devices carried by the penbeam to be readily and nicely adjusted in relation to the paper to be ruled, so that a suitable contact of the former with the latter may be had without any imposition of an excess of pressure of the ruling devices on the paper over that required to mark, the same and also operate to remove the cause of trembling of the ruling devices arising from shocks heretofore attending the sudden stoppage of the drop of the pen-beam carrying the said ruling devices, which shocks were generally eonsequent from the jar communicated to the pen-beam from the striker or striker-bar heretofore employed when that device falls in place on the rest which is provided to stop the fall of said striker or striker-bar.
