EDWARD WAKEFIELD BLAOKHALL, OF TORONTO, ONTARIO, CANADA.

RULlNG-MACHINE.

EPECIPICA'I'ION forming part of Letters Patent No. 317,078, dated May 5, 1885.

Application filed April 17, 1884.

To all whom it may concern:

Be it known that I, EDWARD WAKEFIELD BLACKHALL, of the city of Toronto, in the county of York, in the Province of Ontario, Canada, have invented certain new and useful Improvements in Ruling-Machines, of which the following is a specification.

The invention relates to certain new and useful improvements in ruling-machines; and it consists in the peculiar combinations and the construction and arrangement of parts, hereinafter more fully described and claimed.

Figure l is a perspective View showing my improved mechanism and sufficient of the ruling-machine to exhibit its connection. Fig. 2 is an inside View of the disk, showing the mechanism connected to it on that side. Fig. 3 is a detail of the gate or stop, showing it arranged to raise one of the pens in the penclamp. Fig. 4 is a plan of a portion of the machine shown in Fig. l.

As my invention relates merely to certain operating parts of a ruling-machine, it is not necessary to exhibit the entire machine; nor is it required that I should describe the complete operation of the machine, except so far as it may be affected by the application of my lmprovements.

In the drawings, A represents the main frame of an ordinary ruling-machine; B and G, the ordinary feed-rollers of same.

D is the spindle of the roller B, through which the said roller derives its rotary motion.

E is the ordinary pen-clamp, pivoted, as usual, on the frame of the machine, and located, as indicated, in front of the rollers B and G.

F is the ordinary feed-table of the machine.

G is a disk wheel or plate journaled on a spindle held in an appropriate'bearing-box, H, bolted to the main frame A of the machine. through the disk and has fastened on its outer end a T-shaped box, I, for holding the inner end of the shafts J and K; The lower or outer end of the shaft J is supported by and journaled in the bracket L, which is bolted to the frame A, as indicated. The outer end of the shaft K is similarly supported by a bracket, M, also fastened to the frame A.

N is a friction-roller, the rim of which is preferably covered with rubber, and is of such a size that the said rubber or rim comes in The spindle of the disk G passes,

(No model.)

contact with the surface of the disk G. This roller N is adjustable on the shaft J, and is provided with a suitable fastening, by which. it can be secured to its shaft J at any desired. point, nearer to or farther from the center of rotation of the disk G.

O is a similar friction-roller, secured. in like manner to the shaft K, and similarly held in contact with the surface of the disk G.

P is a gear-wheel keyed to the spindle of the roller B, and arranged to mesh with the pinion Q, fastened to the outer end of the shaft J R is a crank-handle for turning the spindle of the roller B, and through the connection described conveying a like motion to the shaft J. I have shown this driving mechanism simply because it is the kind I am at present using; but it will of course be understood that the gear-wheels might be dispensed with, and also that, although it is advisable that the motive power used to rotate the roller B should be utilized for driving theshaft J, the two parts might be driven-by separate motors.

Before describing the construction of the parts operated by the revolving motion of the disk G, I may remark that the speed of the disk may be increased or decreased with the greatest nicety without altering the speed of shaft J. To understand how this is accomplished, I need only draw attention to the fact that the shaft J lies on a line running from the center of the disk G. Consequently as the motion of the shaftJ is conveyed to the disk Gby the friction-roller N the speedof the said disk will be increased by moving the roller N toward the center of the disk, or the speed of the said disk may be decreased by adjusting the roller N away from the center of the said disk, and

- as this adjustment can be accomplished to the fraction of aninch' the speed of the disk can be correspondingly affected,which adjustment of speed is necessary in order to enable the disk to accomplish all that is required of it.

S is a rock-shaftjournaled in the frame A and having one of its arms, S, extending to apoint near the disk GL WVhen the machine is constructed as shown in the drawings, this arm S of the rock-shaft S extends behind the disk G in such a position that the pin 8, fixed on the inner side of the disk G, will come in contact with it as the disk revolves consesequently at each revolution of the disk the said arm is pressed down till the pin 8 can pass by it, when, either through the action of a spring or weight, the said arm springs back into its initial position. Consequently at each revolution of the disk G the shaft S has a rocking movement imparted to it. The other arm, S, of the rock-shaftS is provided with an extension-rod, t, so held to the said arm by set-screws that it may be easily adjusted in or out of the arm with the view of lengthening or shortening the said arm, as when fastened to it the rod it forms an integral part of the arm.

T is ahorizontal rod suitably, and adjustably fastened by a set-screw, t,to the extensionirod t. The other end of this rod T is adjustably connected by a set-screw, u, to what may be termed a push-plate, U. Owing to the connection described between the push-plate U and rock-shaft S, the rocking motion,before referred to, of the said rock-shaft S will impart a reciprocating motion to the push-plate U. In order to increase or decrease the travel of the push-plate U, the extension-rod t is lengthened out or shortened into the arm of the rock-shaft S, to which it is attached;

and, further, the connection described between the said rod tand the horizontal rod T allows the push-plate U to be adjusted to any desired point on the feed-table F.

Having now described the plan by which I increase or decrease the speed of the disk G, and also the plan by which I convey the motion of the said disk to the push-plate U, it will be well to explain the object attained by this portion of my invention before entering into a description of the other mechanism connected with it. In ruling-machines as now made the operator feeds the sheets of paper to be ruled between the feed-rollers B and C, the motion of which carries the sheet so fed into the machine till it comes in contact with what is known as a gate or stop. This gate or stop is automatically operated so as to permit the sheets of paper so fed against it to pass it at regular intervals, which intervals are regulated according to the size and style of the paper. By the adoption of my mechanism I dispense with the gate or stop as formerly used and substitute in its. stead the push-plate U. Instead of directly feeding the sheets of paper into the rollers B and C, the operator places each sheet 011 the table F in front of the push-plate U, which plate is at the proper interval caused to move forward, thereby feeding into the machine the sheet in a perfectly straight direction and with the utmost regularity, which is necessary for the satisfactory accomplishment of the ruling.

I have before explained that the speed of the disk G can be increased or decreased with out regard to the speed of the shaft J, which maintains a uniform speed relatively to the speed of the feed-roller B. WVhen small sheets of paper are to be ruled, it is of course necessary to feed them in more quickly than large sheets of paper. Consequently thespeed of the disk G must be increased, which is simply and effectually done, as before described, by merely adjusting the roller Ntoward the center of the disk. The pen-clamp E has an arm, 6, fixed to it. This arm is connected by the rodfto an arm, 9, fixed to a shaft, f, passing through a suitable bearing in the frame A, and having fixed to its outer end an arm, h, which latter arm extends close to the surface of the disk G, and is shaped substantially as shown in the drawings, so that the spring catch or clasp i fits over a portion of its end, while the remaining portion extends in toward the disk. By thus arranging the end of the arm It so that the clasp t will only occupy a portion of the said end I am enabled to utilize the motion of the disk G for the purpose of automaticallythrowing the arm it into or out of gear with the clasp, which actions are accomplished by a short and long stud or pin fixed to the face of the disk.

In the drawings I have shown three pins, 1, 2, and 3, fixed in the slot j, made in the face of the disk. These pins are, provided with suitable jam-nuts for holding them in any desired position, and it will be understood that they may be adjusted to different points in the slot.

The arms 9 and 71, connected together by the shaftf, journaled in the frame A, as described, constitute a rockshaft the inner arm, 9, of which is connected to the pen-clamp, as de scribed, and are relatively arranged, as indicated, so that when the end of the arm h is slipped below the clasp i thesaid clasp holds it down, and when so held down the other arm 9 of the rockshaft is held at such an a11- gle that the pen-clamp connected to it is tilted on its pivot so as to hold the pens clear of the paper. In Fig. l the pens are indicated as being down. Consequently the end of the arm his clear of the spring-clasp t. The pin 1 is indicated as approaching the end of the arm h. This pin 1 is a short pin and does not extend over the end of the arm h sufficiently far to come in contact with the clasp '5. Consequently when it reaches the end of the arm h it presses it down into connect-ion with the clasp t, which springs over the outer portion of the end of the arm h, holding it down, as before described, while the pin 1 passes by the clasp, leaving the end of the arm fitting below and held by the said clasp. The next pin (marked 2) is a long one, and extends outwardly sufficiently far to come in contact with the head of the clasp i, pressing down the said clasp, so as to push it clear of the end of the arm h, which, on being thus disengaged, springs up, and consequently the pen-clamp attach ed to the other end of the rock-shaft drops down, and the pens are thus thrown into action until the next short pin comes in contact with the end of the arm h.

From this description it will be seen that the pen-elamp can be thrown in and out of ICO IIO

action at irregularintervals by merely adj usting the pins .1, 2, and 3 in the slot j,.and by multiplying the pins and adjusting them in the annular ,groove the pen-clamp can be.

opposite to the arm h. Projecting pins corre:

sponding to the pins 1, 2, and 3, and fitted into a groove corresponding with the groove j,

' are provided and fitted to the inside of the disk G, so as to operate the arm Z exactly in the same manner as the arm h is moved, a clasp,i, being provided for the arm Z, exactly in the same corresponding position and for the same corresponding object as the clasp t. It follows, therefore, that the rock-shaft, of which the arms is and Z form part, can be operated for the same purpose as the rock-shaft of which the arms g and h form part. Consequently an additional pen-clamp can be operated on the machine and worked at the same time as the pen-clamp E is operated,one clamp being employed for one class of ruling while a different class is being accomplished by the other clamp. In the drawings, however, I have not shown an additional clamp, as the rock-shaft f may also be utilized for the purpose of operating the stop or gate V, the use of which I will describe farther on.

I have already described the location of the shaft K and of its friction-roller O. This shaft K derives its motion,through the said frictionroller O,from the disk G, and can be run faster or slower, as occasion requires, without altering the speed of the disk G. This is accomplished by adjusting the roller 0 on the shaft Kthat is to say, if it is necessary to increase the speed of the shaft K, the roller 0 is adjusted farther from the center of the disk G, or vice versa, the speed being regulated to a nicety,. as the adjustment of the roller on the shaft may be effected to a hairs breadth. The outer end of the shaft K is provided with a spur-wheel, m, which meshes with a pinion, m, attached to the disk n. This disk is provid ed with a suitable spindle, and is journaled so that it derives motion from the revolving of the shaft K.

.W is a rod connected at one end to an auxiliary pen-clamp, 0, which is pivoted in the main pen-clamp E, as indicated. This auxiliary pen-clamp is arranged to hold one or more of the ruling-pens. The other end of the rod W is connected to the disk n, as indicated, the connection being such as shown, so that by adjusting the holding-stud p in the slot so as to be nearer to or farther from the center of the disk the motion of the rod W can be decreased or increased, as desired, in order that the auxiliary pen'clamp attached to its other end may be rocked on its pivot to a lesser or greater extent, as required, the ruling pen or pens held by the auxiliary penclamp 0 being employed for the purposeof forming what is known as a wave-line in the ruling.

In the former part of the specification I described how the gate or stop V was connected to and operated by the rock-shaft Z. This gate or stop V is, as indicated, in front of the pens, instead of beinglocated and operated behind the pens. By thus locating the gate or stop V, I am enabled to adjust it so that the paper being ruled can be held stationary during the period that the pens are being brought into contact with it.

It is not always necessary to operate the stop or gate V as such; but I am able to utilize it for another purposenamely, when it is desired to operatecertain individual pens in the pen-clamp independently of the other pens. WVith that view I attach to the stop V one or more clamps, g, which can be adjusted on the stop V in front of any particular pen which it is desired to operate independently of the other pens in the clamp. This is suggested in Fig. 1, and is also shown in Fig. Iattach to the clamp q a rod or wire, a", and extend it to the pen, 6, it is desired to lift. It will be seen from this that any number of the pens can be operated independently of the others, and in this way any style of ruling desired may be accomplished. .7
