PAPER-MEASURING ATTACHMENT FO R PRINTING-PRESSES.

Application filed March 6, 1920. Serial No. 363,679.

To all whom it may concern:

Be it known that I, BASIL BREWER, a c1t1- zen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have inventeda certain new and useful Improvement in Paper-Measuring Attachments for Printing-Presses, of which the following is a full, clear, and exact description.

The present invention relates to printing presses, particularly large presses, such as are employed for printing newspapers, and to which paper stock is applied in the form of large rolls.

Inordering from a paper manufacturer, rolls of paper for use on presses for prlnting newspapers and the like, a certain thick-' ness of paper is always understood or stlpulated so that since the weight ofv the roll is known, the length of paper on the roll, and hence the number of papers that'can ordinarily be printed from itjcan be determined providing paper of the desired or designated thickness is furnished. It is often the case, however, that the paper manufacturer-does not furnish paper of the proper thickness, the paper being sometimes thicker than desired, in which event the length of paper on the roll is less than it should be, and less than the desired number of printed newspapers is obtainable from a roll.

he principal object of the present invention is to provide a measuring attachment applied to the press in such a way that the amount of paper in length units canbe accurately measured. e

Further the invention aims to, apply a measuring device to a roll of the press over which the paper passes in passing from the roll of paper to the printing rolls, thepoint j The invention may be briefiy summarized as consisting in certain-novel combinationsand arrangements of parts which will be described in the specification and set forth in the appended claims.

In the accompanying sheet of drawings wherein I have shown an embodiment of my invention which operates with high efficiency, Figure 1 shows one printing unit of a standard newspaper press; Fig. 2 is an enlarged view, partly in horizontal section and partly in plan view showing the measuring attachment applied to a spring roller which is adjacent the roll of paper; Fig. 3 is an enlarged side view looking toward the right of Fig. 2, showing the mounting of the spring roller in question with the measuring device removed; and Fig. 4 is a similar View with the measuring device in place.

A printing press for printing newspapers usually consists of a number of printing units, each usually having provision for supporting two rolls of paper, also having two sets of printing rolls, inking devices, rolls or rollers over which the paper passes as it passes from the roll or rolls of paper through the machine, and folding and cutting devices, and numerous other instrumentalities which are immaterial to the present invention and need not be here referred to. In Fig. 1 I have shown conventionally the major portion of one printing unit of a standard press. In this figure 10 and 11 represent two rolls of paper supported in "from the second roll, if the paper on the two rolls is of full width, or if the. rolls are of a length such that single sheets are to be printed, the paper may be run from both rolls at the same time, one roll then being displaced axially with respect to, the'other.

wlfirom the rollv or rolls the paper passes around a roll 13, to which 'my improved measuring device is applied for. reasons to be subsequently referred to, then around other rolls 14 and 15, then through the printing rolls 16, to which ink is applied by ink-- ing means consisting of a plurality of rolls designated generally by the reference character 17. Then the paper passes around other suitably positioned rolls 18, 19 and 20 to the other portions of the press not shown. The roll 13 which is next to the paper rolls may be termed a'spring roll, as its shaft 21 .is mounted in bearing blocks 22 slidable in guideways 23 of brackets 2 secured to the frame-work 25 of the press, the movement of the roll toward the paper'rolls being resisted by coil springs 26, which permit a to and fro movement of the roll 13 as the tension in the paper varies. All the other rolls of the press are generally mounted in nor press and the paper is fed from it, it becomes necessary for smooth operation of the press,'that the roll overwhich the paper passes as it-leaves the paper roll be yieldingly mounted so that it may .act as an equalizer, either moving bodily to and fro in the brackets which support it, or with an oscillatory movement so that the non-uniform feeding of the paper from the roll is compensated for, and an even tension maintained in the paper passing through the machine.

It is to one end of this roll of each print ing unit oft-he press that I prefer to provide my improve-d measuring device which is indicated at 27 in the drawings. The details of the measuring device are immaterial to my invention, and it willbe sufficient to length of the paper which isbodily state that it is mounted on the sliding bearing block at-one end of the shaft 21 which carries the roll 13, so as to move back and forth with the latter, and it is actuated by an extensionof the shaft 21. The measuring of the paper as shown by the measuring device may be in any suitable units, but preferably in length units of any denomination, such as feet or yards.

By applying the measuring device to the spring supported roll 13, a far more accurate measurement is obtainable than ispo'ssible with the measuring device applied to any other rotary part of the press. apparent that slippage between the paper and roll upon which the measuring device is applied, would prevent accurate measurement of the paper passing over the periphery of the roll, but since the roll 13 is spring mounted a'nd adapts itself to uneven feed of the paper, the slippage between this-roll and the paper is negligible. Furthermore,

this roll has a large portion of its periphery engaged by the paper as it passes around it, and is usually corrugated. V A further advantage, aside from that mentioned,"and due to the fact that the measuring'device is applied to the roll next to the roll of paper, is that the accuracy of the measurement is not affected by breakage of the paper which frequently occurs at some point near or beyond the printing rolls. When the breakage occurs, the operator usually is required to'destroy a considerable out" of the machine, but the length of this destroyed paper is recorded on the measuring device, which would not be the case if It is pulled the measuring device were at a distance from .the paper roll or rolls and the destroyed sectlon were removed between the paper rolls 7 and the measuring device.

I am aware of the fact that measuring devices have been applied to certain types of machines, particularly for measuring cloth,

but never to my knowledge has any one suc-' cessfully applied a length measuring device to a printing press to measure the length of paper passing from the roll. 'Nor to my knowledge has any one conceived the idea of applying such a measuring device either to any rotary part constituting a fixed on pects, to what rotary part of the press the. device is applied, though I regard it as of. extreme importance that it be applied to the spring roll adjacent the rolls of paper, and

my invention its'more specific aspects resides 1n such application.

Having described my invention, I claim:

1. The combination with a printing press adapted to accommodate paper in roll form, r

and having a plurality of rolls around which the paper passes as .it travels through the press,inc'luding a yiel-dable roll which may yield under varying tension of the paper, of-

a measuring attachment operatively connected to such roll. I

2. The combination with a printing press adapted to accommodate paper in'roll form,

3. The combination with aprinting press adapted to accommodate paper in roll form,
