Application filed Apri124, 1913. Serial No. 7633334.

Be it known that we. lun-vom' il. Lnslar. and doux i.. ilinius. citizens ot' the United States. and residents oi' Roanoke Rapids. in the. county oL" ilalitax and State of North Carolina. have made certain new and useful improvements in iaper-ilaking lvlachines, oi which the following; is a speciiication.

Uur invention relates to improvements in paper makingl` machines, and it consists in the combinations.. `constriu-tions, and arraiuicaieuts herrie. described and claimed.

)in object of our invention is to provide means tor measuring or gagging the thickness ol a sheet o.' paper just after it has been toi-anal and when it is still inthe wet state bcore beine; ealendcred.

.i further .object ot' our invention is to provide a gage which may be turned so as to b1.- Hf-adable 'from various parts oil the room in which thc machine is situated.

'lurther object oi' our invention is to pri means l'or imlicatingl the thickness nl' ihr paper ai any desired place.

i turthcr object ol' our invention is'to providi a special form ol" giajie which will register variations ol` l'.y loam() ot' an inch in ille thiclv'ness of the paper.

iitlier objects and :nlvantaiesy will appA/ear in the followingl speciiicaliou and thc novel icatiu'es oll the device will be particularly pointed out iu the appended claims.

Our invention is illustrated in the accompanying drawingis tormiup` part of this application in whichlfinurr i is a section through a portion of ilu .levice. the gane being' .shown in elevaiion. hie'. i a section along the line :5M-2 ol hin'. i. liii. Ii is a section along the line Si IE oi' l."i l. Figi'. -l is a vertical section through the faire nu the line fl-i of Fig. i3.

Fie'. is a section along' the line .3-5 of l. and bis'. ii is a section alongA the line ln the makin;v of paper. especially where the paper is made in strips ol considerable width it is the custom to provid a plurality nl' toed devices tor properly i'listribuiingi the Pulp si: as to lorin sheets`ol uuilorrn thickA 'in the initial run el' a mill the linished paper which comes from the calender rolh` is measured or gagged and it' any parfiriilar imi oi the sheet. sarl. as the cczzer, or a poni ion inward one. edge or the opposite adire. b. found thinner or thicker than de- -manner as shown in Fig. 3.

sirable, more or less of the pulp is fed from that particular feed spout which corresponds with thel portion of' the sheet to be changed. ln mills which employ modern machinery it will be seen that a considerable length oi paper is virtually wasted before the pulp feeding devices have been properly regulated. The paper which is not uniform in thickness is generally rejected and only that used which conforms to a certain standard thickness.

.in object of our invention is to provide a gagging device which will gage the thickness ot' the sheet oi" paper before it has reached the drying rolls so that the proper regulation ot' the pulp feeding device, may be made before the paper has passed over the dryingir rollsN thereby obviatinp,r the loss and delay t'ornierly occasioned.

ln carrying' out our invention we provide a base roll l whose shaft 'lx is mounted in bearings 2 on the` main frame, 3 of the muchne. A yoke l is secured to the frame 3 bv means oi bolts 5 or in any other suitable This yoke siraddles the bearings 2 and'iis provided with an upwardly extending threaded arm 6. The arms i on each side of the machine term. together with the nuts 6X, supports for a transverse frame T. The latter provided with a longitudinal slot 7X which eX tends for a distance approximately equal to the width ot the sheet ot' paper to be formed.

Secured to the frame 7 and arranged to be adjusted in any position therealong are a plurality of gage members like those shown in Figs. l and description of one ot these .frage members will snfiice since they arx all alike.

ln Figi'. i we have shown the frage. as consistine; of a base plate S arranged to support a central standard which is provided with a central bore arranged to receive'a rod 10. 'lhe standard Si has a slightly reduced extension 9" at its lower end arranged to enter the slot 7* (see Fig. (i). The plate 8 is provided with a pair of arc-shaped slotsv 8* ar ranged to receive the threaded arms 11 which extend upwardly trom integral cross members 12. 'lhe latter are disposed be- -neah the i'rame 7. Nuts lli are provided for clamping: the standard Si in position.

The lower end of the rod l() is threaded to enter one end of a turn buckle 14. A forked rod 1.3 is threaded to enter the other end of casingA 18,

20. The latter is divided by means of a l graduated scale 21so as to indicate a differ ence of 1/10,000 of-an inch in of the paper. The rod 10 is secured toa U- shaped rack member 22, which. engages a pinion 23 on a shaft 24. The latter' bears a gear 25,v which engages 26 on a shaft 27 bearing a hand 28. At the upper end of the U-`shaped rack member 22 is' a guide stem 29 Which projects through an opening in the casing 18'or guiding the rack in its movement. Springs 30 are provided for exerting a downward tension on the rod 10. y

From' the foregoing description of the various parts of thedevioe the operation. thereof may be'readily understood.

The paper sheet or band 17 passes from the press roll 31 over the base roll 1 as shown. in Fig. 2. Gages such as those described are secured to the ntrarne 7 at various intervals along the frame. In'Fig. l We have shown three of these gage members, but it will be understood that more or less may be provided without departing from the spirit of the invention. As the paper passes underneath the roller 16 the thickness of the paper will be accurately registered by the gage. The hands 28 of these gages should, of course, registert thev same thickness, but in case they do not it will be .at once apparent to the tion of the sheet should be fedmore 'or less pulp. There is therefore no necessity of completing the drying and calendering of the paper and thus losing the paper which has passed the base roll.

By loosening thenuts 13 the standard 9 may be turned so as to face in any direction so as to be read from different parts of the room. The provision of the turn buckles l 14 permits an accurate adjustment of the vgage should be roller 16 so as the roller to remain parallel with the of the base rolll even if the face of the turned at an angle.

lhe ages may be shifted along the slot so tlat any particular portion of the sheet may be gaged. The gage members may the thickness gage frame carried by bof said operator which porto permit the axis 16X ot Lioaaie be quickly removed or replaced. It will be 1. In a paper making device, a frame, a
