BULING MACHINE.

Application filed January 5, 1926. Serial No. 79,354.

This invention relates broadly to an improved ruling machine 'of the automatic type, such as is used for mounting of a mul tiplicity. of pens cooperating to draw lines on so-called ruled paper.

\Vhile the invention is not limited for use in connection with any particular type of ruling machine, it has been designed with a viewto permit it to be applied in the form of an attachment, to a conventional Hickok automatic ruling machine.

In machines of this kind there are a plurality of longitudinally spaced striker beams rockably mounted on the top of the machine and adapted to carry the ruling pens. Under ordinary conditions, cooperating cam means is provided on the-striker beams and the machine frame for lifting the beams up at predetermined intervals to render the pens momentarily inelfective. There are times, however, when it'is desired to lift these pens up at intervening intervals and to hold them' suspended and disengaged from the paper to facilitate operation.

The gist of the presentinvention is to provide a structure, in the form of an attachment, which maybereferred to'as a striker beam underlift. This is a structure which is mounted on the under part of the conventional framestructure and which is manually operated to permitthe striker beams to be lifted up aifd held in such lifted state for any required length of time.

Briefly, the attachment comprises a rock shaft journaled for angular rotation in appropriate bearing brackets carried by one of the side bars of the frame structure. This rock shaft is operated by a depending push rod which is in turn connected with a pivotally mounted lever. The lever is provided with a foot piece for reception of the feeders foot. with the rock shaft and extends above it and is engaged with the various-striker beams, whereby a depression of the lever will serve to lift the push rod, to rock the shaft, and to simultaneously lift all of the beams to disengage the pens from the paper.

The structural advantages, features, and

other results will become apparent from the following description and drawing.

In the accompanying drawing forming a part of this applicatiomand in which like numerals are employed to designate like parts throughout the same Figure 1 is a side view of an incomplete Then, novel means is connected automatic ruling machine of the type specitied showing'the improved attachment associated therewith, and themanner in which it operates.

Referring to the drawings indetail, the

reference character 1 indicates the base portion of a ruling machine of the Hickok type and the reference character 2, see F ig.- 1, represents one of the side bars adjacent the top portion of the machine. As before intimated, machines of this kind are provided with a plurality of longitudinally spaced transversely extending striker beams (not shown), which carry the'ruling pens. At the end of each beamis a part generally represented by thereference character 3. This may be conveniently referred to as a lifter arm. Cooperating with this arm in each instance is a rotatably mounted driven member 4 which is provided with cam means (not shown) to engage the adjacent portion of the lifter arm for raising it at predetermined intervals. These details form no part of the present invention.

The invention comprises, as before indi cated, a plurality of bearing brackets 5. These are mounted on the side bar 2 at the approximate points shown in the drawing. Mounted for rotation in the brackets is a horizontally disposed rock shaft 6. Depend-v ing from this rockshaft is a vertically disposed push rod '7, which is pivotally connected at its lower end to a horizontally disposed lever 8 The lever is provided (see Fig. 2) with an apertured ear 9 which is pivoted in any suitable way to the base 1. It will be noted that the outer end of the lever has a depending part 10 and a horizontally eXtendingpart llterminating in a foot piece 12 adapted for reception of the feeders foot.

Connected tothe'opposite end of the lever is a coiled spring 13 which serves to normally maintain the parts of the attachment in inactive position. Cooperating with the rock shaft, we lind a plurality ot separate devices generally reprcstmted by the relic-rence characters l-;l-. llach device comprises a stem composed of a lower section if) and an upper section in, these two sections being pivotally connected together by the joint structure shown in Fig. 2.

liilounted on the frame bar on the inner side are guide brackets l7 through which the sections 16 of the stems are slid-able. Attention is now directed to El and l: wherein it will be seen that the upper stem section it) terminates in a substantially Tshaped head. \.djustably and slidably connected with this head, a plate l8 carrying upstanding spaced parallel ears 19 between which an arm 20 is mounted. it will he noted that this arm terminates in a curved extremity :21. which :utlaptcd to cooperate with the aforesaid lifter arm 8, (see F l). The adjustment oi" this arm 20 must he very accurate. 'llheretore 1 provide a pair of adjusting screws which cooperate therewith and with the plate 18 to change the elevation ot the curved extremities. A retaining screw 23 is also provided. The retaining screw, of course. serves to maintain the plate 18 in ditlerent adjusted positions on the head 17.

Each device 1st isconnected with theat orosaid l'OtK shaft 6 through the medium of a crank arm ill (see Fig. 5). Hence, when the rock sha'i't operated, all oi? the devices will be simultaneously actuated. In order that this result may be obtained, the aforesaid push bar T is connected as at with one of the devices as shown in Fig. 9.

Cooperating with the intermediate portion of the lever is a pivotally mounted latch 26 having a counter-weight '37 formed on its bottom. This latch pivotally mounted upon the base of the frame bar 1, as shown in Fig. 1. This latch is adapted to engage a lug extending at right angles from the inner side ot the lever. In addition there is a stop pin 28 to limit the movement of the latch in one direction. nected to the intermediate portion of the latch and is then connected with the pivot ally mounted operating member 30 which is adapted to be engaged by the operators foot to release the latch. The latch normally swings to a position to engage the lug and this happens every time the pedal or lever is depres ed. This latch arrangement makes it. unnecessary to maintain the foot in posi tion on the pedal. It is understood that the device is usually operated by the feeder, but the latch and operating means is not within convenient; reach of the feeders foot. Accordingly the latch and the cooperating parts are controlled by the operator.

The operation of the machine is as fol lows:

Moreover, a link 29 is con-,

nos aeeo Under ordinary conditions, the attachment does not affect the automatic operation of the ruling machine. However, at the operators or tendons discretion, the attachment may be brought; into play so that instead of being operated by the automatic means, the striker beams may be raised up at any time by the manual means provided. Under normal conditions, however, this attachment is held in iueliective state by the spring 13. By placing the toot on the pedal 1:2 and depressing the lever H, a l ter releasing the latch, the push rod '7 may he raised, to operate the rock shat't t3 and the devices H. In turn these devices simultaneously lift up the. arms 3, and consequently raise the pens on the striker beams from the moving paper. No doubt, those skilled in the art; to which the invention relates. will be able to obtain a clear mnlerstanding of the invention and the manner at operation. Tiltl'EIEOlO, a more lengthy description is thought unnecessary.

ltlilltn changes may he made within the tield of invention claimed, and may be re sorted to if desired.

Having thus described my invention, what I claim as new is: l l

i. As a new manufacture, an attachment for an automatic ruling machine adapted for simulttmemisly raising a plurality of pen equipped striker boan'is, comprising a rock sha it, means for mounting the rock shaft on said ruling machine, an operating lever, an operating connection between the lever and said rock shaft, and a plurality o'l separate devices associated with the rock shattand adapted for cooperation with said striker beams.
