b all whom t may concern:

Be it known that I, Rioimnn A. Minimi., a citizen of the United States, residing at Atlanta, in the county of Fulton and State of Georgia, have invented certain new and useful Improvements in Guides for Ruling- Machines, of which the following is a specitication.

'.lhis invention relates to ruling machines, more particularly to the guide cords therefor, and has for its essential purpose, to devise a means whereby a single continuous cord may be utilized in place of the large number of guiding cords now used on all ruling machines.

Another object is to obviate the disadvantages attending the use of a plurality o f cords whereby it is necessary that each individual cord be adjusted, thus saving considerable time when preparing the machine for ruling.

A further purpose is to perfect a guiding means for the sheets of paper so that said sheets, uniformly and evenly, may be delivered to the inking pens.

Another advantage is that the use of a single thread requires only one knot, as against a separate knot for each individual cord thereby reducing to a minimum the possibility of breakage, thus increasing the life of the same and saving the time necessary for repairing broken threads. The single knot likewise eliminates the interference of many knots with the ruling pens and so gives an unbroken line.

The apparatus is of such design that it may be readily attached to the frame of the ordinary ruling machine.

With these and other subordinate objects in View, my invention is further set forth iii the following specification and appended claim and illustrated in detail in the accompanying drawings, Wherein:-

Figure 1 is a side elevation of a ruling machine with my improved guiding means thereon. Fig. 2 is a side elevation of the upper guiding cords. Fig. 3 is an end elevation of the same. F i0'. 4 is a side elevation of the guiding means at the opposite end of the machine. Fig. 5 is a plan view of a section of Fig. lt, and, Fig. 6 is a rear end elevation of Fig. It.

Referring now more in detail, to the several views shown, wherein like letters of reference indicate the same parts in the different figures shown, the character t designates the usual conveyer belt or apron on the ruling machine frame o and X one of the run ning pulleys therefor. Said belt cooperates with the guiding element b to receive the blank sheets of paper as they are fed from the shelf c and carry said sheets forward to the ruling pens after the known manner. c, c. representl two detachable brackets se cured to the posts at one end of the frame a, said brackets are provided with trunuious at their upper ends for the shaft of the grooved roller or pulley and Z designates a larger grooved pulley which is mounted within journal blocks d upon the frame of the machine. rlhe pulley (l is the driving member for which pur]i ose it is provided with, an operating crank c. \Vithin the sides of the frame posts b are located two eom'liensating or directing guide pulleys L" whose purpose will be presently described.

Secured upon the frame at a suitable distance from the end supporting brackets and in alinemeut therewith, is a secondary bracket c', removably secured to the frame, having journaled therein the ordinary upper and lower guiding pulleys g and f/ respectively. The lower guiding pulley g is provided with tensioning means Il. whereby the tension of the several convolutions or guiding elements of the cord may be regulated. Intermediate tlie primary and secondary brackets c and c respectively is the guiding bar a fixed transversely of the frai'ne. Thus the course of the upper guiding means of the machine is the following; the thread f runs from the groo'ved roller y' in the direction of the arrow through the pulley 7c', thence transverse of the machine through the second directing pulley k, thence around the driving roller (l, across the stationary bar a', around the adjusting roller g, around the roller g and again to the roller y'. It will therefore be readily seen that the convolutions of the thread f are directed to the starting point of the roller (Z, by which means it is again started on its course around the several pulleys y', cl, g, and g respectively.

Referring now to the figures disclosing the lower guiding means at the opposite end of the machine, s designates the main roller for the ruling cloth t, and t is a roller for supporting said cloth on its return after passing over the roller s. Z refers to the endless guiding cord, comprising the plu- -ality of separate guiding elements, correspending to those shown at f in Figs. l, i as limited to the structural details disclosed and 3, and in its arrangement for (rperation these guiding elements are strung upon the rollers g, s, r, r, and mf, thence to g in the order given, said pulleys 1 and m are ournaled in the end frame supports or posts Z2. Alter having passed about these pulleys, the required number et times the cord is directed from the end oit the pulley m, through the guiding pulley 0, (as shown in Fig. (i) then transverse of the machine through the pulley j), from which pulley p it passes on to the roller, y, shown in Fig. and thence around the main or cloth guiding roller s, and so on it continues its operation.

The roller fm, is provided with grooves whereas the roller g is smooth as against the contrary arrangement which is usual. Said roller m is i'itted with adjusting screws n, by means of which. proper tension may he brought upon the several turns oit' the string Z.

lWhile I have shown my improvement applied to a ruling machine l do not wish to be understood as limiting its scope merely to a. machine of this type, for it may with slight modilications, be adapted to machines generally of this structure wherein belts or guiding cords are used for conveyine', such for instance as folding machines, the feed mechanism of printing presses etc.

l further do not wish to be Yunderstood in the accompanying illust-rations, but reserve the right to malte such changes therein as will better adapt the apparatus to its purpose.

lllhat l claim as new is,-

'l'fhe combination with a ruling machine having a een'veyer belt, of a guiding means for the sheets carried by the belt, said guiding means comprising a single endless cord arranged in a plui'ality of conyolutions adapted to lie in intimate Contact with and travel in the direction or' movement of the belt, greoved and smooth pulleys journaled within the machine and on which said guiding means is arranged, said grooved pulley adapted to hold the several convolutions at proper relative position and to guide the same, a pair of single pulleys disposed at either end of the grooyed pulley and adapted te receive the cord from one end oi? a smooth pulley and direct said cord to the opposite end of the grooved pulley, and an adjusting device associated with one ot' said pulleys whereby to uniformly tension the several convolutions of the cord.

In testimony whereof l atlix my signature, in presence olf two witnesses.
