PAPER-RULING MACHINE.

Appflication filed October 23, 1923.

7'0 @ZZ 10710712` may concer/i1.'

.lic it ltnown that I,`JACOB Lo'rz.y a citizen of the United States, and a resident of llarrisbmg, in the county of Dauphin and State ot l.)ennsylvania, have invented certain i new and useful Improvements in Papei'-Ruling Machines, ofwhich the following is a specilication.

My invention relates to improvements in paper ruling machines' and its consists of the constrlutions, combinations and arrangements herein described and claimed.

An object of the invention is to provide means for preventing ruled paper from adhering to and following the return side of the upper cloth after having left the end roller of: a ruling` machine.

A further object of the inventionis to provide an arrangement ot middle cords adapted to cooperate with the means aforesaid but provided for the speciiic purpose oit holding the ruled paper down on t-he under cords so that the paper traveling on said cords may neither shift its position nor that the leading edges may curl up.

[another object of the invention is to provide the combination of middle cords, constituting a part of the invention, with the under cords of a ruling machine so as not 4only to hold the ruled paper down on the under cords but permit the ruler to see through between the sheets as they pass.

A further object of the invention is to provide a brush roller for the purpose of Vdetaching the ruled sheets from the return side ot the upper clotln said brush roller having the secondary'purpose of dislodging any adhering d irt or dust on said cloth and thus tend to keep it clean.

Other objects and advantages will appear in the following specification, reference being had to the accompanying d awings7 in which Fig. 1 isa longitudinal section of a ruling machine illustrating` the application of the. brush roller and the middle cords, j

ing how the paper is caused to lay down on the under cords,

Fig. G is an end elevation of one ot the adjustable hangers in which the brush roller is mounted, and v Fig. 7 is a side elevation of the parts shown in Fig. 6.

The ruling machine to which the invention is applied in the drawings may be regarded as of a conventional design. It is not necessary to describe all of the ruling ma chine in detail, only a comparatively small part being involved so far as the invention is concerned. The ruling machine comprises a frame 1 which is supported by uprights 2 and 3 at the trent and rear respectively.

The so-.called upper cloth 4 runs over front and rear rollers 5 and G which are cousiderably larger than the numerous inter mediate rollers T over which the cloth is guided in its travels. The upper cloth also passes over the bed board 8. The upper cords 9' are arranged in such a manner as to hold the paper which is to be ruled down on the upper cloth el. as it passes across the bed board 8.

In addition to the rollers 5 and 6 the ruling machine is also provided with a lower front roller 10 over which the lower cloth 1l passes in such a manner as to convey the ruled paper to the lay boy 12; A suitable number of idlers 13 is providedv in order to properly support the lower cloth 11. Working in conjunction with both the rear or end roller G and the lower front roller 10 arc the under cords 14 which are trained over the end roller 6 in such a. manner as to hold the ruled paper against the upper cloth fl as it passes around the end roller from the top to the under side. The reader will understand that the under cords 14 are necessary to keep the ruled paper against thc cloth,l otherwise the paper would drop olia as soon as it rounded the end roller.

The invention consists of the brush roller 157 which acts in combination with the upper cloth 4 andthe middle cords 16 which act in combination with the under cords 14. In order that the brush roller 15 may func tion as desired, the return side ot the upper cloth 4 is directed over a turning roller 17 by means ot' which the direction of the return side of the upper cloth is changed abruptly` as clearly shown both iu Figs. 1 and 3.

K The brush. roller 15 may be composed ot a body ot Wood or any other suitable material, faced with cloth 18 which has a nap 19 suitable to perform a brushing function against the upwardly moving part of the returning upper cloth 4. The brush roller 15 turns in the same directioiras the end roller 6, this turning being accomplished by the lay boy belt 20.. In View ot. the fact that the roller 17 is so disposed in respect to the roller 15 that the upper cloth 4 is caused to turn abruptly upward, the clockwise motion of the brush roller becomes contrary tothe directi-on of'inovement of the `aforesaid part of the upper cloth.

The nap 19 of the cloth therefore brushes downwardly upon the return side of the upper cloth and exercises two important functions; one, any sheets ot paper which tend to adhere to they return side of the upper-cloth by static electricity, tor example. are. brushed down until they properly tall upon the under cords 14; two. an)v dust` dirt or ink adhering to the upper cloth Yis brushed away so that the upper clothrcA mains in a clean condition.

Iherother element ot the invention, dcscribed as being the middle cord 16, begins its function immediately` that the brush roller 15 ceases its func-tions.V The ruled paper having been brushed down from the return side .of the upper cloth 4 runs along Y' mg edges the upper strand ot the under cords 14 towardthe lower front roller 10. The wind resistance has a tendency to causethe leadi of the. ruled paper to'rise, sometimes sniiicientlytomisplace the paper 'on the-under cords and causer improper feed ing both around the roller 10 and intothe lay boy 12.* Again. the Apaper sometimes has-a. tendency to coilnp completely. The object. ot the middle cords 16 is to keep the ruled. papertlat'on the under` cords 1.4 so that neither ol" Ithe 'foregoing contingencies may arise.

l'An arrangement ot' rollers 21,v 22 and 23- (ltig.l 1;) furnishes tbe support ter the middlemcords 16. The `latter .roller grou-ved as shown in Fig.' 4. The rollers 21 .and 22..are smooth; ,Flachis mounted in brackets. 24 and Q5-which are fastened to thetront'uprights 2li These rollalso carry pulleys Q6 which .are driven by means of a belt27' trom a. pulley 28.011 the adjacent. idler 13. The grooved roller 9.3 is supported in' hangers 29 which, are fastened beneath the longitudinal Yrails ot the traine. The turning roller 17 is mounted in corresponding hangers i The mounting oi' Ythe. brush roller 1,5 is ditfcrent trom the vhangers described in that provision 'for the adjustment ot the brush rollers is madetherein. 'l`he stub shafts of the brush roller are journallcd in hangers 32 which are pivoted at 3% on pendent brackets 34 in such a manner that the brush roller may be made to hear againstI the upper cloth 4 with more or less pressure as conditions may require.

Each pendent` bracket 34 has a pair ol lugs in which set screws 3G are mounted. These are intended to be screwed in or out. in respectto the head 87 ot the hanger il; (Fig. (5) so that the hanger may be rocked in one` or the other direction.

There is another advantage which accom panics the use of the middle cords 1G in addition to that ot holding the paper down on the under cords 14. The ruler in attending the machine. regards it an advantage to be able to see through the various moving cords and follow `the ruled paper on its way to the lay boy 1Q. The reason for this statement is that attempts have been made to train the return side of the upper cloth 4 over the under cords 14 in such a manner as to hold the ruled paper down on thc under cords en route to the lower front roller '10. This of course obscures the ruled paper. liv using the open middle cords 1li. the ruler mayv 'Follow the course ot ther paper and therefore take full advantage of the satisfaction which this particular provision ai'liords.

The operation may1 be briefly reviewed to advantage. The ruled paper alpiproachcs the cnd roller G. being conveyed in that. direction by the upper cloth 4. The under cords 14 are necessary to hold the ruled paper against the cloth as it passes around the roller G'. The upper strands ot the cords 14 form the conveyor by which the ruled paper is carried toward the lower trout roller 10 after it has passed thc roller G.

rlwo elements oi the im'cntion.y namely. the brush roller 15 and the middle cords lll. cooperate in insuring that the ruled papel' shall traverse the upper strand of the cords` 14 in a proper manner. The brush roller l5 performs its functions by brushing against the return side ot the upper cloth 4. and tor this purpose. the return .side of the upper cloth is made to make an abrupt turn at the turning roller 17 (Fig. 3). 'lhc action is well illustrated in Fig.

Assume a sheet of ruled paper to adhere to the return side ot the cloth 4 by means. for example., of the attraction of static clcctricity. The turning roller 17 moves in a clockwise direction and so does thc brush roller 15. The side by side disposition ol these rollers causes one to brush down while the other mores upv` the action of the nap 19 on the cloth facing '1S being to loosen ithc tree edge ot thc paper. graduall)v sweeping it down. as shown by the` various dotted line positions in Fig. 5 until the paper lies flat on thc under cords 14.

No sooner is the paper properly laid lill lull

llll

upon the cords 141 than the middle cords 16 come into action to keep the paper flat on said cords. The middle cords 16 prevent the leading edges of the paper from flying up, as for example, by the resistanceot' the air, until the lower front roller 10 is reached, whereupon the ruled pape-r passes onto the lower cloth 11 and finally into the lay boy 12.

It may become necessary to adjust the brush roller 15 in respect to the turning roller 17. This is accomplished by the set screws 36 (Fig. 6) which, by proper manip ulation, serve to turn the pivoted hangers 3Q so as to move the brush roller 15 into the desired position in respect to the roller 17. It is to be added that besides serving to brush the paper from the return side of the upper cloth 1, the brush roller has the added function ot keeping the cloth 4 clean. The nap 19 brushes out any ink sediment and removes any dust that may have settled on the upper cloth.

IVhile the construction and arrangement of the improved ruling machine as herein described and claimed, is that of a generally preferred form, obviously modifications and changes may be made Without departing from the spirit of the invention or the scope ot the claims.

1. In combination with the upper cloth and under cords ot' a ruling machine between which ruled paper is adapted to pass, means over which the return side of the upper' cloth is trained causing` a sudden change in the direction of movement, means including a nappy cloth-faced roller operating at said place, said nap brushing upon the return side of the cloth to loosen any paper tending to adhere thereto and causing it to fall on the under cords, but avoiding raising any nap 0n the upper cloth by virtue oi being soft, and another set of cords having a portion arranged parallel to and traveling with said under cords to keep said paper in place thereon.

2. In combination with the upper clot-h and under cords of a ruling machine between which ruled paper is adapted to pass, a turning roller over which the return side of said cloth is trained to abruptly change the direction of movement, a brush roller adjoining said turning roller having a facing of nappy cloth adapted to loosen sheets of paper tending to adhere to the upper cloth and cause them to fall upon the under cords, means causing the brush roller to revolve in a direction opposite to that of the movement of the return side of sai/d upper cloth, means disposed over said under cords keeping the paper iiat thereon as it travels with the under cords, and means permitting adjustments ot' the brush roller in respect to the turning roller so that the nap of the cloth acin may bear on the upper cloth with accor ingly various pressures.

3. In combination with the front upright and upper longitudinal members of a ruling machine frame, the end roller and lower front roller, and the under cords trained to run thereover; a pair of rollers disposed adjacent-to said lower front roller, brackets by which said rollers are supported on the front uprights, a grooved roller disposed adjacent to said end roller, hangers by which said roller is suspended 'from the longitudinal member, middle cords trained over said pair of rollers and said grooved roller so that the lower portion runs close to and parallel with the upper portion ot said under cords to hold down sheets of paper carried by the latter, and means for dri-ving both rollers of said pair so that said lower portion moves with the under cords at the same speed.

4L. A ruling machine having a moving upper cloth, a turning roller by which the return side of said cloth is caused to make an abrupt change in direction, a revoluble brush roller situated neXt to the turning roller and a facing of material upon the brush roller having a soft nap bearing against the upper cloth at said abrupt turn to continuously and lightly brush said upper cloth while moving.

5. A ruling machine having a moving upper cloth, a turning roller by which the return side of said cloth is caused to make an abrupt change in direction, a revoluble brush roller situated next to the turning roller at said abrupt turn in said cloth, said roller having a facing of nappy material bearing against and continuously brushing the upper cloth while moving, means causing the brush roller to turn in a direction opposite to that ot the movement of said cloth, and swinging hangers in which the brush roller is journalled so that the brush roller may move toward and away from the turning roller.

6. A ruling machine having a n'ioving upper cloth, a turning roller by which the return side of said cloth is caused to make an abrupt change in direction, a revoluble brush roller situated next to the turning roller at said abrupt turn in said cloth, said roller having a facing of nappy material bearing against and continuously brushing the upper cloth, means causing the brush roller to turn in a direction opposite to that of the movement of said cloth, swinging hangers in which the brush roller is journalled so that the brush roller may move toward and away from the turning roller, and means including set screws bearing against a portion of each hanger on opposite sides for fixing said swinging hangers in various adjusted positions.

7. A paper ruling machine having a travelling" conveyor cloth for carrying sheets, a revolublesheet stripper-roller, and a Cloth facing upon said roller having a nap contacting the conveyor cloth, said nap being SoftY thereby preventing disturbance of the conveyor cloth nap.

8.. A paper ruling machine havin-g a travel-1mg conveyor cloth for carrying printed sheets, a revohible Sheet stripper-roller7 and a facing of cloth upon said roller hav- 10 ing a nap brushing against the Conveyor cloth to continuously remove any adhering dust, ink, etc. and thereby keep the eon.'e \jor Cloth in a clean condition.
