Thefobjelct ofthev invention'is to provide mechanical means yfor rnaintaining the proper relation vbetweenthe traveling'note #sheet and lthe tracker barbr yother'coperlinvention `to provide positively; actuated vmeans for restoring the' notesheet ltoits vnormal position, i. le., itsgtrue cour`se,rwhen it has been diverted therefrom; to provide a shifting, device for so, adjusting the sheet which shall' 'be controlled .by the lateral movement ofthe s'heet,itself;fand further, tol y provide such a kdevice which shall be simple j its construction :andf-operationf'and not w liable to be broken or sodisarranged yas `to Y render the samefiinoperative.

(In the' accompanying drawings, vFigure closer's, showing theirA arrangementrelative to the tracker-board; Fig.f3 isa similar view `of a modifiedy form ofthe invention; Fig..V 4 is a sectional view, taken transverselyto the tracker bar in that form of theinve'ntionA shown in Figs. 1' and 2; Fig. 5' is an end ele vation of one of the sheetrollers showing a modified form of circuitbreaker and closer mounted thereon; and FigQGis a side eleva- 1 f'tion of theV same.

Means are provided whereby thefmovement of the shifting devicezis controlledby the lateral displacement of the note-sheet 5.

In the. form of the deviceA herershown .a

pneumatic operatingrmechanism is emp-loyed -V which comprises acasing 21 having flexible side and bottom wal1s,zas indicated at 22 and 23, and provided .witha diaphragmormov-- able partition 24'l dividing the interior. of the casing into twocoinpartments orA chambers V25 and 26.v This diaphragm ormovable partition is `operatively connected tothe lever Y 19, and, in thepresent instance, hasfan upwardly .extending arm 27 rigidly, secured thereto and connected with thelever 419 by a rod 28.'

' `Each chamber 2fand 26 has a conduithor tube 29 cemmunicatingtherewith and connecting the same with a passage 30 formed `in the base 31 upon which the Vopera/ting mechanism is mounted.` AThese passagesBO are, `in turn', connected with asuction pipe 32 which communicates :with a suitable suction apparatus which may be of any suit-f` able character, but is here shown asyasuc- Vtion fanv34f The conduits 29v communicate with `the passages 30 through valve cham- Y. bers 35v having flat top and bottomjwalls.

The bottom wall of each valve chamber has therein a port 36 Vcommunicating with the corresponding passage `30 and the top wall of fthe chamberhasfone `or vmore ports'37 connecting the valve chamber with the atmosphere. A fiat disk-like valve 38 is arranged withineach vvalve chamber 35 and normally restsupon the lower wall thereof and closes the port 36. The suction in the passages30 serves to retain the valve-mem-V bers 38.1tirmly upon their seats and efectu-4 ally close communication between the suction pipe and the chambers 25 and 26.'

W'ith the valve members in this positionthe chambers are. in open communication with the4 atmosphere through the conduits 29 and ports?. The valve members 38 are actuated by electro-magnets,which, in the present instance, comprisesolenoids 39, to the coresv of which are secured the valve stems `40 of the valve members 38. The solenoids 39 are'connected in separate circuits 4l and 42respectively, and each of thesecircuits has a circuit breakerand closer which is notesheet.

sheet 5 is a movable guide 43, which, in the present instance, constitutes one member of a circuit breaker and closer. `This movable memberis preferably formed of thin resili`v ent metal and bears gently against the adjacent edge o the note sheet Vwhenthe lat- Vtenis in itsnormal' position, are., when it is traveling in its proper course with .relation f to the .tracker bar 4.. #This 'pressureof' the contact members `43 against the opposite"V 'edges of the note-sheet would serve to a cer- V tain extent to counteract any Vtendency on the part ofthe note-sheetto depart from its properccursej,v Any appreciable diversion Y of thelnote-sheet fromV its true course will,

however, move the contact meinber43on` thatlside towardfwhich the note-sheet is diverted into engagement withthe fixedconi tact member 44 of' the ,circuit breaker and closer. These `circuit breakers and closers maybe of any suitable construction and mayV be'supported from Vthe frame l in any suit! able manner, but lhave here shown the fixed' Contact. member 44 as mounted on one of r the iside members of thefframeV 1 from whence iteXtends inwardly to a point not far Vremoved from the edge'of thewnote sheetl and is then bent rearwardly, as shown at 45, and has rigidly Vsecured to the rear end thereof the movable contact member 43, i

the tivo members being insulated Von'e'from .the other, vas shown at 46. ,The circuit breakersand closers maybe located at, any suitable points along the edges of the note-` sheet where they` will be actuated by the lateral displacement of thenote-sheet, but, in

asmuch'as thenote-sheet is tobe maintained in a predetermined relation to the tracker bar, it is rusually desirable'to mount the circuit breakers and closers as near the tracker "I L bar as is convenient and I have, inthe present instanc.e,shown ,the circuit breakers and closers so mounted. L n

rlhe operation of the device will be readily understood from the foregoing description i f V and it willbe'apparent that should `the notesheet be diverted from its course toward the left, as shown in Fig. l, the contact member 43 ofthe circuit breaker and closer on'the.

The otherA chamber26 beinglin com- Y munication v with the atmosphere, I the yadjacent side of the diaphragmQlfwill be subjected to atmospheric Vpressure and, conse-` f'quently, the diaphrafrgm will be -moved toward the chamber 25;- Thisj rInoveeement" of the diaphragm rocks thefarm 27 and, through `the medium ofthe rod 28, the lever 19 ltoward'the left, therebyshiftingV the roller 2 toward the right and restoring V.the note-sheet tok its normaliposition. As soon as the note-sheet 'has been restored .toll its Y'normal positionr the movabler contact memberllv will returnftoits normal posit-iomthe circuit ilewillbeinterrupted,andthe solenoid39 willr be fdenergized and the valve 38 will move into engagement with its seat on e 'again equalizing the" pressure in the two vrso chambers and 26 and permitting the dia-l phragm to returnffto its normal or .centralv position. f
