PAPER-RULING MACHINE.

SPECIFICATION forming part of Letters Patent No. 558,764, dated April 21, 1896. Application filed November 1, 1894. Serial No. 527,599. (No model.)

To all whom it may concern:

Be it known that I, LUoIUs S. BrenLow, a citizen of the United States, residing at Harrisburg, in the county of Dauphin and State of Pennsylvania, have invented certain new and useful Improvements in Paper-Ruling Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements in paper ruling rnachines, and the special points of novelty have reference to the following particulars: first, the organization and arrangement of the I 5 change-gear and intermediate idlers by which motion is transmitted from the driving-gear to one or both of the striker cam-heads at the rnlers 0r right-hand side of the machine and within the side rail, whereby the change-gear is accessible to the ruler without going to the other side of the machine, and whereby a certain shaft heretofore necessary in these machines is eliminated; second, to improved means for supporting the pen-bar and for ad- 2 5 justing it vertically and laterally; third, to

improved means for adjusting the gate-shaft without reaching inside of the rail.

In the accompanying drawings, on which like reference letters and numerals indicate corresponding parts,Figure 1 represents a side elevation of my improvements in connection with a part of a ruling-machine; Fig. 2, a plan view of what is shown in Fig. 1; Fig. 3, a detail plan view of a portion of the right-hand 3 5 rail with the guard-plate; Fig. 4, a detail sectional view looking toward the inner side of the right-hand rail, the section being taken on the line 00 00 of Fig. 2; Fig. 5, an enlarged side elevation of the standard, the pen-bar with its attachments, the means for adjusting the pen-beam, and the .means for adjusting the gate-shaft Fig. 6, a detail sectional view and elevation of the turret-block and the screw for adjusting it vertically; and Fig. 7, a plan view of the standard, 850., shown in Fig. 5.

My improvements are especially applicable to the rulingmachines known as the Hickok machines, which have been on the market for many years; but they are also applicable to other types of ruling-machines.

The letter A designates one of the upright cam-blocks.

posts, 13 the right-hand side rail, and C an intermediate post or support for the rail, the rear post not being shown. This rail 13, I out outor recess, as shown at D in Fig. 3 particularly. \Vithin these recesses I place the camheads E, which are of the usual construction. They are respectively carried upon arbors of i the common apron or cloth supporting rollers. Usually and heretofore these cam-heads have stood within the inner side of the side rail. Experience has long developed the fact that so located they were difficult of access by the ruler when adjusting the cam-blocks of these cams, according to the design of ruling to be done. I place these cam-heads practically outside of this rail and recess the rail more or less to receive them. I then apply a guard-plate F, secured by screws or other means G, adapting it to be removed or swung out of the way when the ruler is to adjust the Thus while the cam-heads are guarded and the ruler is protected from having his clothes caught by them, they are, nevertheless, readily accessible by adjusting away the guard-plate.

Referring now to the train of gearing for transmitting motion to the cam-heads, the letter I-l designates a plate secured to the inner side of this right-hand side rail. A part of So the plate depends, as shown at I, and has a slot J. In this slot is mounted a shaft K, secured to the outer end of which is a tightenin g-lever L, while on the inner end is a nut M.

By removing the nut the change-gear P may be placed upon the shaft K, the nut being screwed back to hold it on. The position of this shaft in the slot J is determined by the diameter of the change-gears, of which each machine has a set embracing several diameo ters, so as to change the speed of the camheads. The change-gear P and the gear 0 are practically one gear, as they are placed side by side and interconnected by any convenient means, sayapin p, passing through, 9 5 as shown in Fig. 4. The outer of these gears O meshes with a gear Q, carried by the cloth or apron feed-roller arbor. A gear R meshes with the gear Q and is carried by the upper feed-roller.

The plate H has two fixed studs 5, each of which carries a gear-wheel 'I and U, respectively, meshing with each other, and the former meshing with the change-gear P. The gear U in turn meshes witha gear V, mounted on a short shaft which supports the first cam-head. Thus motion is imparted to that cam-head. This cam-head carries a toothed disk or gear X, which in turn meshes with a gear Y, carried on a shaft Z, held by a tightening-lever Z in the slot of ahanger Y. A gear X meshes with the gear Y, and being connected to the second cam the head rotates the latter, the shaft X carrying this second camhead with its gearX. This arrangement does away with a shaft formerly necessary in these machines. It will be observed from Fig. 4: that the entire train of gearing R, Q, P, T, U, and V is in mesh and in the same vertical plane and on the inside of the rail and post. Heretofore it was usual to place the gears It, Q, P, T, U, and V on the outside of the rail and post and on the other or left-hand side of the machine. This necessitated a shaft which extended through the cam-head E and its roller from the righthand to the left-hand side of the machine, so that such shaft could support at said left-hand side said gear V, where it could mesh with the said train of gearing. Now then, by transferring these gears from the left-hand to the right-hand side of the machine, then by placing them in- V side of the rail and post, and then by placing the cam-head E outside of the rail (so as to give room for the gear V) I dispense with said extra shaft and make the machine less expensive, more compact, and more convenient for the user.

In some machines the second cam-head with its striker and pen-beam is not used, in others it is employed but not always operated. In the latter case the gear-wheel Y is lowered by adjusting its shaft in the slotted hanger Y until the gear is out of mesh with the gears X and X. The second cam-head then remains idle, as also its striker and pen-beam.

Referring now to my improved means for supporting and adjusting the pen-beam, a designates said beam, and b the usual penrest, pivoted thereto and held and adjusted by the usual screws 0, and carrying the supporting and adjusting screw 6, which holds the pens just in touch with the paper when resting on the ledge f, or above the paper or cloth when resting upon the turn-button g. This ledge f is cast in one piece with the standard h. The standard It is formed on a footplate 1', mounted 011 oblique ways j of a base plate 70. These oblique ways in their relation to the base-plate and bed-plate do not form any part of the present invention, having been patented heretofore and being owned by my present assignee.

In the standard 7r is mounted a turret Z, formed of a cylindrical block of metal adapted to slide up and down in the standard and to rotate or partially rotate therein. A screw passes through this turret and connects with to the inside of the rail.

the pen-beam through a cross-piece 0 on the screw, pivoted in lugs g on the plate r, which is fastened to the end of the beam at. This screw is used to adjust the pen-beam laterally. When the plate 2' is slid back and forth on its ways, the pen-bar is adjusted longitudinally, and during this adjustment the turret Z partially rotates in the standard h to allow for the change in the relation of the parts. The turret has fitted in the lower end an adj Listing-screw 8, held by a set-screw t and fitted at its lower end in a bushing u, carried by the foot-plate 2'. A lock-nut v with a handle is used to lock the screw 5 after it is operated by the milled nut w to adjust the turret up or down, so as to aline the pen-beam vertically. Thus it will be seen that the turret has a rotative and an up-and-down movement and that it carries a screw on, (having a bindingnut m,) which connects with the pen-bar. The turret also has a reciprocating movement by reason of the standard being adjustable generally lengthwise of the machine.

Referring now to the means for adjusting the gate-shaft, a screw 2 is mounted in the bed-plate 7c, and this screw meshes with a worm-nut 3, mounted upon the screw 4, which is slidable in the bearings 5, projecting from the plate 70. A bearing-block 6 is fastened to the end of the screw 4 and receives the gateshaft '7. Thus by manipulating the screw 2 the worm-nut 3 is rotated and the screw 4, 011 which the nut is mounted, is bodily reciprocated, and hence the shaft 7 is adjusted longitudinally, so as to effect its true alinement. The operator can operate this mechanism without reaching inside of the rail, but, on the contrary, has merely to turn the milled head of the screw 2, that stands next to him on the outside of the machine. It should be stated that the shoulder 8 and the head of the screw 2 prevent it from moving lengthwise, the screw being unthreaded between the head and the shoulder. It will also be observed that the location of the cam-heads outside of the rail permits the location of the gears close At least for this arrangement it is necessary that the first camhead should be outside, while for the other reasons named the second cam-head is also placed outside of the rail.

I have hereinbefore described the guardplate F as. removable to afford access to the cam-heads. I wish to be understood, however, that by constructing this plate with the depressions or cut-away parts F the ruler may have access to the cam-heads without actually removing the plate, though the latteris preferred.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. I11 a ruling-machine, the combination with the side rail and a plate secured to the inner side thereof, the plate having studs and a depending slotted portion, gears mounted on said studs and a shaft adj ustably mounted in the slotted portion and carrying a changegear.

2. In a ruling-machine, the combination with the side rail, a plate secured to the inner side thereof and having studs and a slotted portion, a change-gear whose shaft is ad justably mounted in the slot, and other gears mounted on said studs, cam-heads located on the outer side of said rail and carrying gears, an adjustable gear intermediate of said latter gears, and a gear on the shaft of one of the cam-heads and in mesh with one of the gears carried by the plate.

3. In a ruling-machine, the combination with a standard, of a turret mounted in the standard to slide up and down and to partially rotate, a screw under the turret and between it and the standard, carried by the standard and connected to the turret to adjust it up and down, and a screw passing diametrically through the turret and connected with the pen-beam.

4, Ina ruling-machine, the combination with an adjustable standard, a vertical screw carried thereby and projecting upward there from, a lock-nut for the screw, a turret slidin gly and rotatably mounted in the standard, above said screw, and connected thereto for adjustment thereby, and a screw passing diametrically through the turret and connecting with the pen-beam.

5. In a ruling-machine, the combination with the gate-shaft, a screw having a bearing for the shaft, a worm-nut on the screw and another screw meshing with the worm-nut and having its manipulating end located near the outer side of the said rail of the machine.
