To all whom it may concerm" Be it known that l, CHABLU-HGBEL a citizen of the United States, residing in East Orange, county of Essex, and State of New Jersey, have inventada certa-in new and 'useful Indica and Adjusting Mechanism, of which the ollqwing is aspeciiica tion.

- This invention is an indicating and adjusting mechanism adapted for use in differ# ent arts for the p ,af the adjustment of wor lumber-s an for 'visually indicating su n adjustment of .said

members. v

The invention-.will be hereinafter described in connection with a rolling mill forVK reducing the thicknesses of metal bars,

beams, or other metal products, for which purpose the newmechanism is especially Zil'edapted, but it is to be distinctly under'-y t0 this especial application, for the reason that said mechanism may be used to advantage in other arts, y

In. its broad aspect, the invention embodies an indicating mechanism, a member adapted to be operatedV at will for setting .the indicating mechanism in either of a number of sitions for determining the adinstallent o the machine to be operated,

and means operated by the movement of the aforesaid member for automatically con trolling the operation of the machine, auch automatic operation Alof the machine taking place subsequent to, and in accordance with,

the adjustment ,of the indicatorl as determined y the manipulation of the* aforesaid member. t

Mmspccisuysmm sie invention m- 40 bodies en ajm' e; indicating mechanism toria roll i v,mill `wherein ya roll ad justingmechanism 'is dperatedlhy anelcctrc motor. Seid motor is startedwtoratically each atimes metal `bar ort-the like sothnlt ere .adjusted auto' tica ifito the req ind d" to v1:extpassagcof e ber V ete., and sairl adjudzmejiit of ther-olliA Ein like manner, autnmaticall arrested' or Vme '59 decent em, readies non determined nl ne adjustment s uw indicator devices. A i V e one Yator to con-` trol ne or a., bel of mills the purpose of adjusting .elchnull so as to regulate the pass between the rollsh'of each m1 llS each time a piece passes between said ro The adjustment of the mechanism may be, and Breferably is, performed by the opcrater w and between the ro e of the mil whereas the actual adjustment of the roll or rolls is performed by mechanism, preferably automatic subsequent to the passage of the metal piece 'between said rolls whereby a substantial saving in time and l aber is attained be' ile a metallriece is passinlg through sides securing an accurate adjustment of the rolls relative to each other in each mill, one operator being' enabled t'o attend to a numbei' of rolling mills.

l'urtllel'xllore,1 my invention makes rovision for the successive adjustments o the roll or rolls of the mill to secure a gradual and pro asive reduction in the width of the passetween said rolls, thus meetin the demands which arise in the practical ro ling of a bar, beam, or other metal piece.

lFurtherinore1 the invention embodies means operated by power and under the easy quick control of the attendant, for raising one roll of a mill relative to the other, in order to separate said rolls after the ieee shall have passed for the last tim'e tween the rolls, thus placing the mill in condition to begin operations on a fresh 'tion of the rolls in the mill, irrespective of the number of times said rolls may have been adj usted2 thus enabling the operator te.

determine qick and accurately the next ad'ustment whic should be given to the no ls of -a particular mill.

Another advantage from a practical standpoint which is secured by the indicating mechanism is that the operator is able to set the indicating mechanismv by an effaceable indicatin mark so as tocom nsate for the or lost motion o the `parte which operatetlie roll adjusting mechanistn,y thus enahln the operator to determine with exactitu e the adjustment which should Abe 'ven toitherolls to secure passes of the wi hs required in securing the progrelsive induction of the metal piece.

In the'ggeccmpanying drawings I have and the field coil, b

inustmed one mami emidimeni of the I invention, but tiie constructi shown therein is to be understood as illustrative, only, und not as dening the limits of the iiivenl tion.

Fig. 6 is a view taken longitudinally throughthe mechanism of Fig. l showin the vari- Fig. 3 is a vertical cross ous rear devices and the automatically operated circuit controller. Fig. 7 is an end view showing my indicatin and adjusting i mechanism in eoperative re ation to a metal rolling mill, and Fig. 8 is a plan of the parts shown in Fig. 7.

In Figs. 7 and 8 of the drawings I have shown an ordinary rolling mill, A, the roll, a, of which is in coperative relation to screw operated adjusting mechanism, a'.

o screws are shown in Fig. 8 as being connected by a cross shaft, a2, for the purpose of simultaneously operating said screw' operated adjustin mechanism. The power for driving said a justing mechanism is furnishedgi the present instance by an electric motor,= shown in Fig. 8, the armature, b, of said motor being shown diagrammatically in Fig. 5.

` beveled The rolling mill, A, is connected operatively .with the indicating and adjusting mechanism through theagency of a shaft, which is geared to the cross shaft, a2, as shown in Figs. 'i' and 8, and on one end portion of said intermediate or connecting shaft, W, is provided a worm, W'. This worm meshes directly with a Worm ear, W, which isle 'ed Vat W to@ shaft, i, the latterforming, one offtheshafts of the indicating and adjusting mechanism, which mechanism is mounted on a suitableitable or support, C.

The several working parts of the indicating and adjusting mechanism are carried or supported by a main frame, C', shown in Figs. 1 and 2 of the drawings. This main .frame is equipped with appro riate bear ings, w, for supporting one en portion of the shaft, W, and with other bearin s, w', in which is journaled ,the shaft, l. Said frame'is provided, also, with shaft bearings, e, e', adapted to support a tubular shaft, z", and a shaft, S, the last mentioned shaft, S, being disposed in alinement with the shaft, W3. The shaft, S, extends through, and is concentric with, the tubular shaft, i', and at one end said shaft, S, is next to an end portion of the shaft, 73, see Fig. 6.

Shaft, S, carries a handfoperated member, G", and shafts, Ws and z', are rovided with bevel gears, G', G, rcs ective y, said member, G, having a beve inion, G, which, with gears, G', G, comprise a train of bevel gears, which train of gears may, for convenience, be designated as an .epicyelic train. Gear, Gf, is ke ed or otherwise fastened rigidly to shaft, lli", whereas gear, G', is ke ed or otherwise rigidl fastened to hol owA shaft, i. Member, Gil, is a spider positioned intermediate gears, G', G', the hub of said spider being keyed or otherwiserigidly fastened to that end portion of shaft, S, which is adjacent to shaft, W.

Spideror operating member, G vided being fastened rigidly is proto the arms of the spider, as shown in Fig. 4, whereby rim, G,

may easily be grasped b hand for the purpose of turning the spi er manually to any position desired in order to set the indicating mechanism and the stoppingdevice or controller which makes and breaks 'the motor controlling circuit. Spider, G, carries the ear inion, G2, the latter being mounted oose' y on said spider for rotation vfreely thereon, and this gear inion, G2, meshes directly with the teeth ot gears, G', G", carried respectively by shafts, W3, and i', whereby pinion, G2, operatively connects the large gears, G', G, of theepicyclic train.

The spider, G", of the member, G, which is operated at will is provided with a stop lug, X, shown in Fig. 4 as extending beyond the periphery of hand Wheel, G, and in the normal position of the s ider and` its member, G, said stop lug, is in. engagement with a stop, X', the latter beingv Secured to a tixed part, c, of frame, C', whereby the coacting parts, X, X', limit the rotation in one direction of spider, G5 and member, G. Under certain conditions spider, G", and its member, G4, are adapted to be locked against rotation in either direction bythe beforedescribed parts, X, X', and b the adjustnient of an electrically operate locking dog, Said do is shown in Fig. 4 as being adapted for s iding movement in fixed part, c, of frame, C', and said dog is connected pivotally with the plunger, O', of a solenoid,

O, the coil of said solenoid bein included in an electric circuit. VThe solenoi langer-1)', is shown as having a head, O, w ich nii the with an external rim, G, the latter 1 Vwhich is inscri portion of an u ri upward movement of the lunger is adapted to close the circuit throng contacts, O, O, shown in F i s. 1 and 5, for a purpose which will herona ter a pear.

Bevel gear, G, ormin one member of thc epicyclic train is provi ed with a toothed' run, 3, said rim being concentric with the gear and fastened rigidly thereto lav any E To shaft, S, isrigidly secured a gear, S',

appropriate mechanical devices, su stantiully as shown in Figs. 1, 3 and 6. Wfith this toothed rim, Z3, is ada ted to coperate the toothed end of' a, loc ing dog, Z2, the latter being slidably mounted in part., c, of frame, C', as shown` in Fig. 3. Said locking dog is connected ivotally with plunger, l', of a solenoid, t 1e coil of which is-in'- cluded in an electric circuit shown in Fig. 5 and, hereinafter described.

The visual indicator employed'in my new mechanism embodies in its construction a rotilting;r and slidin drum, 1, the surface of to indicate the units of measurement. As yshown in Figs. `1 and 2, drum, if, is provided with a spiral indicating line intersected by per endicular indicating lines, the whole furnis ing a compact scale adapted to afford a lar e number of units of measurement. This inieating drum is provided with a hub, i', which is formed inreriorly with a female Screw thread adapted to work on a xed screw, i', the latter bein mounted in a stationary position on the hea frame member, c, whereby the indlcatmg drum is snp `orted on frame, C,by means which are a apted to secure the rotating and longitudinally f sliding` movement of said drum. Coperatcator or pointer, 2"", herein shown as an arm fixed rigidly to frame member, c', and ter-' ing with the scale on drum, il, is an indiminating; nl an index point which is adjacent to the inscribed face of scale on drum, 7.

Screw. is, is hollow and through it. passes one member, i, of the indicator operating shaft, said shaft being mounted in vertically :dined bearings, i, which are rovided on upright frame member, c.l T e indicator operating shaft consists of two lengths, it, i, which are connected-rigidly by a separable coupling, i", whereby le part, c", of Sold shaft may be disconnected temporarilyfrom part., m order to' adjust ther drur, il, as may be required. The upper part, i, of indicatorA shaft extends loosely through fixed screw, i, and it has' a` sliding connection with drum. i', such as by means of a Vfeather shown in Fig. 2,' .and the rotation nof this shaft imparts rotsrymovcmetto drum, i',

'while the operation off'screw, i", and hub, i",

of said drum drum.

The indicator operating shaftis provided at its lower part.' with. bevelv ar, a?, which meshes directlywithy aV beve gear, i?, the latter being mounted directly on holl'ow gvesthfsliding travel to said the electric motor, B, for the operation of the roll adjusting mechanism of mill, A.

havin meshing engagement with gear pinion, t on a shaft, S3, the lutter beingr mounted in appropriate bearings. c2, of frame, C. A/hollow screw, S", is fixed rigidly to one beating, c2, of said frame and it yloosely incases a part of shaft, S, said hollow screw extending from .benl-ing, ci', inwardly toward pinion, S2, on said shaft, Si'. Shaft, S3, is provided witha longitudinal feather, S4, .and this feather enga es slidably with nut, S', the latter being s own in the form of a sleeve which has threaded en gagement with the fixed screw, S". Said nut, ST, is shown in Fig. 6 as a sleeve open at one end to receive screw, S, and closed at its other end by a head, S, seid nut being rotated by reason of its feathered conncctlon, S, with the shaft, S3, and the screw Vct'mnectionot nut, S', with screw, S, imparts the sliding' movement to said nut when it is rotated'bythe action of shaft, S'. Said 'nut is connected rigidly to drum, S, forming the main element of the circuit controller, but said nut is insulated electrically from said drum, S, by an" suitable form of insulation' indicated at by the nut and the drum are mechanically connected for rotation as a unit, but, they are electrically insulated from each other.

The rotation of spider, G", by hand nets through the epicyclic train to rotate the indicator shaft, i, for the purpose of setting the indicator drum, i to the required position, undsimultaneously with this operation of setting the indicator drum, said spider, G, rotates shaft, S,"and gears, S', S2, for, the "purpose ofturning shaft, S, thus imparting movement to nut, S", which;

by its Vengagement,with fixed screw, S, operatesto impart rotary and sliding motion to drum, S, thereby setting the movable where,

member, S", of the circuit controller to a l position which will determine thecurrent to be admitted to electric motor, B, for the;

,09615011 .0f thejrolt adjusting meelnnsm associatedwith rollin mill, A. .Copersting with rum, SF', if ,che Ain cuit controller 'is a plurality of conm# FyF, F, F', which are connected-sepa ratcly b conductors, f, with the coils, r, of 4a plut ity of resistance switches, R. An-

er contact, F, is in electrical engagement with rotary and sliding drum, S", said contact, F, remaining normally in engage ment' with said? drumlS", during its rotar and sliding motion w creas contacts, F, F

F2, F", are adapted-to be disengaged succes sively from the dxfum as it slides in one direction under the in uenee of screw, S, acti on nut, S1, ofthe drum. Contact, F, is con j nected by conductor, f', to a terminal, f, adjacent to one of the automatic switches, D, which open and close the `circuit through motor field, b. i'

Each resistance switch, R, is controlled electrically, and they are connected in par allel in a circuit which is normally open. The switches, R, are so related to the bank of resistances, R', and to the rotary and sliding drum of the controller that the eurrent Vadapted to How lto the motor will be controlled by the number of switches which are .in or out of use. Y

The rotation of drum, Ss, in one direction brings contacts, F, F', F, F, into electrical engagement with said drum successively, the number of contacts ,so enga ed with drum, Ss, depending upon the e ree of endwise travel given to said drum y nut, S', and this beingvdependent, furthermore, upon the adjustment given by hand to the spider, G. Contacts, F to F3, control the amount of resistance, R', which isincluded in the circuit, through which resistance the 'current is required to flow prior to its admission to motor, B, and provision is thus made for automatically regulating the admission o current to the motor so as to gradually start the same until it reaches full capacity, as well as regulating the reduction of the current by gradually shutting it oill from the motor w en stopping it, as will hereinafter appear.

In conjunction with the automatic means for varying the resistance in the motor cir cuit, the mechanism is equipped with a hand operated member, shown in Fig. 5 as a switch level', G, adapted to occupy ,a neutral or idle position between contacts, g, fj', and l1., h. Contacts g', 11,', are electrical y connected with each other, thecontact, g', being branched at g2 onto one lead, J', of the two mains, J, J', while contact,rg, is in series with the coil of solenoid, O. Contact h, is in series with coil of solenoid, l, and contact, h', is connected with one contact of: a group of contacts, Ff, the latter being branched Y onto conductors, f, leading to the coils o resistance switches, R.

A main switch, K, cbntrols the admission of current to motor circuit, J, J", one lead or main, J', of which includes the motor field, two of the motor switches, D, U, and the motor armature, while the other main, J, includes resistance switches, R, bank of resistanccs, R',. and the two remaining motor switches, D, U

Switches, D, are connected in parallel and included in the motor circuit when switch lever, G, is shifted in the direction down indicated by the arrow, Z', in Fig.

" throu h motor etme lwhereby the latter 4of travel or adjustment are in comic 5, so asA to brid contacts, h, h', thus energizin solenoi Z, and the solenoids, d, switc es, D for closing the circuit field, whereb the motor is and driven in one ireetion. The other switches, U, are connected in parallel `and are adapted to be included in the vmotoraeircuit when Vswitch lever, G, is shifted in the opposite or\.n'p direction, thereby energia' solenoid, O, andthe solenoids, u, of switc es, U, the operation of said switches reversing the flow of current through armature of the motor so as to drive tfie latter in the o posite direction and thereby actuate the rolladjustin mechanism of mill, A, for se arating and increasing the width) passes between said rolls. y

The magnetic controller system shown in Fig. 5 is similar in its general features to other systems now in use for the same generalv urposes, except that I have added thereto t e automatic circuit controller. It is not considered necessary, therefore, to enter into a detailed description of the motor circuits, the several switches, resistanees and other parts shown in said Fig. 5.

The operation of the apparatus is as fole rolls of the pass or lows: Assuming that the rolls of a metal .rolling mill, A, are 0 receive an ingot or s ab on the first pass,`

ned or Separated to that main switch, K, is closed, switch lever, G, is in a neutral or idle position, and drum, Se, is free from contacts, F to F. As the metal piece on its iirst pass oes throu hv the mill, the operator rotates and whe@ G, and turns spider, G, in the direction o f arrow in Fig. 4, and to the extent/rearqired to setl drum, i7, to the osition for indicating the adjustment of mlll rolls for the second pass, said indicator drum being operatedV to travel in a downward direction for a predetermined distance throu h the gearing between hollow shaft, i', an indicator shaft, i, i. As spider, Gr", is turned by hand in a direction to move sto lug, X, away from stop, X', gear pinion, (le, rotates on its axis for the reason that it is in mesh with lgear, G', the latter being temporarily locke from rotation by the worm gear, W, of shaft, W, being in ear with worm, W', on shaft, W, `hence t e rotation of gear pinion, G2, as it moves with spider, G", operates to,rotate gear, G, and hollow shaft, shaft imparts rotary motion to indicator shaft, i, for adjusting indicator drum, as previously stated. It should be noted that the graduations on the indicator drum denote a unit of travel of the roll in mill, A; preferabl the units undredths (1/100) f ,lh inch, but they may be any other stan' ard of measurement, say one sixteenth (1/16? of an inch.

Simultaneous y with the adjustment ofA indicator drum, 7, to denote the adjustment of the mechanism for setting the mill rolls at the second pass, spider, (1, and member, G4, operate to set the drum, S", of the circuit controller to a position for closing the motor circuit so that motor, B, will operate the roll adjusting mechanism automatically `in order that the rolls will he caused to approach cachjother to the distance required for the second pass immediately following thc exit; from the mill of the piece undergoing the lirst rolling operation. The described operation of setting the drum of said circuit controller is performed by the before described operation of `turning spider, Gr". and member, G, and it is due to the rotation of shaft, S, to which s ider, G, is key-ed. Said shaft turns gears, S2, shaft, Si", and nut, t, whereupon screw, S, cooperates with shaft, Sa, ingiving gliding and rotary motion to drum, S. Said drum is thus' brought into engagement with one or more contacts, F, F', F2, F s, the number so engaged depending upon the endwise movementicf drum, S, and determined in the first instance the angular adjustment of spider; G, an( member, 'Gi The 'engagement of fingers, F, or F, F', or F, E 2,

or F, I*",`F,: F3, with drum, S, completes the circuit with a'corresp'onding number of resist'aiiceswitches, R, so as to close the circuit"'"throullij a predetermined bank of re- `sistances, adapted to iow to mot-or, B, when motor switches, D, are closed.

The adjiistment of yindicator drum, i', and *rotary controller drum, S, are, or may be, made whilc :a piece is moving through the airst pass ot' mill, A, and when said .piece P'elears the mill, the operator may, at any time suhscquent thereto or immediately thereafter, move switchlever, G, in the direct-ion of arrow, Z', in Fig. 5 to the down tor, thus bridging contacts, h, h', so that thmcnrrent flows through solenoid, l, and through solenoids, d, of motor switches, I), thereupon current is admitted to motor, B, ,for opcratin the roll adjusting mechanism of mill,-,A or moving one or more of the rolls ltlo the position required for the second pass. As the current energizes solenoid, l, core, Z",.is drawn upward and dog, l", engages with toothed rim, l, on gear, Gf, thereby locking gear, G3, shaft, i', and indicat-or mechanism from movement. The u i ward movement of core, l', ,not only loc s gear, G3, and the indicator mechanism, but m-ot'or switches, D, are cut into theworklng circuit by part, Z, of core, l', closlng the I.circuit through contacts, l, l.

4The rotation of gear, G2, having caused "drum, S, to complete the circuit of one or more resistance switches, R, engaging with one or more contacts, F, F', F2, F, and the solenoid, l, having closed the circuit through and regulate the current tained, sto

motor switches, l), and switch lever, (i, having been shifted t0 the required position, it follows that the full strength of the curxent capable. of passing through the resistance then inthe circuit is admitted to thel motor. Now, when motor, B, operates the roll adjusting mechanism for moving the roll` or rolls to the second pass, shaft, W, is rotated hy shaft, a', and worin, W', imparts rotary motion to worm ear, '2, shaft, il, and gear, G. The rotition of said geur imparts rotary motion to gear pinion, G2, and as the teeth of this gear inion, G2, are in mesh with the teeth of g ar, G, the latter being held in a locked o.`tion b dog, '11%, con trolled by solenoitl l, it follows thit er pinion, G2, must rotate onV its axisfn at the same time travel around on thefface of locked gear, Gr,y This movementhofgear t wart] travel of the drum, intoelectrical--ctm-`v tact therewith, and as the drum is withdrawn from the successive contacts, th'efsistanoe switches, R, are rendered inactive successivel and the switch levers, r',`dr0'p out one a ter the other, thereb dually cutting the bank of resistentes, ,finto the motor circuit and gradually slowing down the speed of the motor until the last contact, F', is released from drum, S, at which time the motor is stopped. When this end is atshou der, X, of hand operated member, 1", is brouglht into engagement with sto X', but s other parts, t e stop. l2will be forced downward somewhat against the magnetic pull of solenoid, l, for'the reason thatvtho coactin'g angles of the teeth in the locking wheel', l and the face of the stop, l2, are so shaped and proportioned as to permitv said drift or ould there result a -sliglrxt rift or coasting action. of the roll adjustin mechanism, or lost motion ofibs coasting motion to the mechanism withoutresnltin in injury to 'the cooperating parts. t this time all the operatmg parts are returned to normal sitlon, switch lever, G, having. been shifte back to its neutrai. sition, and while the ieee is being rolle 1n the second pass of mi l, A, member, G, and spider, G5', may be again operated to set the mechanism for adjusting mill, A, to the third pass so that by the manipulation of switch lever, G, at the proper time, mill, A, may be again adjusted so asto result in the production ci fhtthird pass, these i', will turnand drive indicator shaft, i, s", so that indicator drum, i', will travel upoperations being repeated an indefinite number of times, and at each time the desired automatic operation of motor, B, and adjustment of indicator mechanism will be secured. Now, when the piece shall have been rolled in the last pass of mill, A, or at any time in the operation of the mill, it may become necessary to se aratc the rolls so as to return mill, A, to t e condition of the first ass in order to mani ulate a fresh ingot. 'lEhe return of mill, to the first pass is effected by the power of motor, B, controlled .through the instrumentalities embodied in the system of Fig. 5. Switch lever, G, is shifted in the opposite direction, or to the up position, by moving. it to a position where it bridges contacts, g, g', whereu on current flows through solenold, 0, for t e purpose of lifting core, O. This results in dog, O2, being moved into the path of stop shoulder, X, and the head, O, of the core makes the contacts, O, 0. Dog, O2, coperates with stop, X', to ld'ck X between theml and thereby hold member, G, and spider, G, from movement in either direction, and core, O", by engagin with said contacts, 0*, O, com letes t e circuit through motor switches, whereupon said switches are operated to complete the circuit through the motor armature in the oppositie direction to that completed by switches, D. The operation o shifting switch lever, G to the left`brought it into engagement with one or more contacts of the group, F, which are connected with the coils 4of resistance switches, R,-and thus the coils of the resistance switches, R, will be energized one after the other, whereby the motor will operate the roll adjusting mechanism to separate the rolls of mill, A. The rotation of shaft a", during the return of mill, A, to the condition of the first pass, drives shaft, W, which actuates worm, W', worm gear, W2, and shaft, W", so as to rotute gear, G', and this gear will in turnl operate to rotate geariinion, G, on its axis. As spider, G", is locke b dog, O2, and stop, X', Whereas gear, G, is iee to rotate, being free from engagement with dog, l,it follows that the rotation of gear pinion, G2, bv the action of shaft, W, will cause gear, G, t0 rotate on its axis, whereupon hollow shaft,

ward on screw, i. The indicator drum 1s returned automatically to normal position at the Sametime that ,the roll operating mechansm is in action to restore mill, A, to the condition of the irst pass, but the le turn of thc mechanisms to normal positions may be arrested at the will of the operatori' who is able to stop the parts whenI 'thoygl reach the desired positions.
