By pulling on the chain 28, the sliiitt 19 may be rotatedto'i'otate the axles and drums to wind up or let out cablesi'or the purpose of raising or lowering'tl' e pilei'. Asthe running wheels are loosely, mounted on the axles, the e I b t l l' tl "h l as es m y e ioatcc Mfloiln ie a ees ithout causing movement of the carriagethe bottoinof tate on the axles which are locked against revolution by the worm gearing, so that there is no possibility of axle rotation which would cause raising or lowering of the piler during its transportation. If bralvs may be applied to the running wheels to prevent truck creepage during raisingor lowering of the pliler, but ordinarily, this will. not be required. Obviously, the drums l7 and worm wheels may be connected otherwise than through the axles, and it will therefore be understood that the construction herein described may be varied in detail without departing from the spirit of the invention. The kier 11 may constitute one of a series of similar triers or other containers arranged in row, and in such case the traclr 1.2 will extend over the row-so that the piler may be transported from one container to the other eat the row.

The piling mechanism is contained within and supported by an annular frame which may be regarded as stationary in so far as the elements of the piling mechanism are concerned. This frame is provided with externallyprojecting lugs or brackets '26-, to which the supporting cables 24 are connected. A trusto-conical, centrally apertured cover 27 is removably mounted on the frame to protect the piling mechanism within the frame from droppings ol bleach liquor or other. corrosive liquid. The lower edge of the frame is inwardly turned a'short distance to provide a raised seat or hearing face 28, and also an upstanding flange 29 at the inner edge of the seat, which flange is outwardly sloping in its upper part, as at 30 and shmvn mostclearly in Figure l. The lower edge of the frame is preferably provided with a plurality oi" radially disposed ribs 31 adapted to rest on the rim of a kier mouth and support the mechanism thereon solidly and without an y tendency to rock or creep, such as right he experienced with two plain surfaces it there was any unevenness or ioreign matter between them. I

A circular il-lateiln is proviiilcd to t'" within the frame and to rest upon the seat 2-8. The lower surface of this plate is provided with an annular groove in which the flange 30 is received and with which the outer wall of the groove is in bearingg contact. The groove is somewhat deepor than the flange, whereby the up er part of the groove is unoccupied and co 1 tut es b an annular channel above the flange 529. P

reason of the seat 28 the plate is rotatably supported and is maintained iii rotation about a fixed centre, which is the centre of the casing, by its engagement with the flange 29. The seating portion of the plate is provided with an annulardownwardly opening annular groove 84' adapted to hold lubricant and distribute the same inwardly and outwardly on the seat 28. A short distance desired,

plate groove wall and would in course of time fill the annular channel and overflow, so as to drop into the lrier. This contingency is avoided by the provision, at suitable intei; va-ls around the plate, of ducts or passages between the passages 37 and leading out: wardly troin the channel 33 to the periphery of the plate, so as to clischar 'eany accumu lation raised seat. Any accumulation oroil'may be drawn from the frame. or casing from time to time by removal or the screw plug; 39.

Above the groove 35 the plate isprovided with gear teeth 40 to mesh with a worm 41 fixedly mounted on a sh-att 42 journalled in a housingll attached to the frame. One etzid of the shaft 4-2 is provided with a pulley or the like i i, by means of which tr. e shaft may be rotated throuoh belt drive 45, or other suitable means, trem a motor-46 ino 'an ed on the frame iXteriorly thereof.

A post 54 is secured to the plate at oj'point diametrically oppositethe vertical conduit sectionand has secured thereto, by a clevis 55-, an inclined brace 56 which is preferably adjustable as to length and extends from the clevis to a lug 57 on the elbow 51, to which lug the brace is attached. This brace serves to support the upper end of the inclined portion 48 and part of the weight of the upper section 47, The elbow 52 is provided with lugs 58 which extend outwardly over the top of the section 49 and are rigidly connected to the plate 32' The triangular structure of the brace and conduit section 48 is steadied against swaying'laterally of the plate containing it-by the lugs 58 and by the cover 27. The lugs 58 serve also to keep the weight of the sections 47 and 48 oil the vertical section 49- The upper section 47 of the conduit preferably tapers slightly from its upper end to its lower end and is provided at'its upper end with a reinforcing ring 59, upon which is mounted a hollow ring or annulus (50 having an inwardly pro ecting lower surface (31 vrovided with a )luralit of OJODIHOS 62 l l- .7 l z:

communicating with the interior of'the ring and preferably directed to a point on. the

axis of the section some distance below the ring. Thering is retained by a depending flange (33, which has a'running fit with in the ring 59. The ring 60 and the section i? are relatively rotatable. An inlet 64: is provided for the ring (30, to which inlet may be connected a flexible conduit 65 to deliver afiuid,'such as bleach liquor, to the ring. The taper or" the section 47 permits the cen-' tral opening of the annulus 60 at the upper orlarger end of the section to be at least as large in diameter a d preferably larger thanthe lower opening of the section. The lower end of the section is provided with a reinforcing ring 66 screw-threaded or otherwise tormed for releasable attachinenttothe upper end otthe elbow 51, which projects through the central opening of the cover 27.

A cape or water shed 67 in the form of a downwardly curved ring is caught between the reinforcing ring 66 and the elbow and overlies the upper edge of tl1e cover 27,.so

will be readily seen, ncr'ely a cylindrical for rotating the section, whichpinion may. conveniently be an integral, outwardlyprojecting, toothed flange. Thelower end of the elbow 52projects into the ring68 and the ring has a smooth running fit thereon; Preferably the rlng 68 is nwardly flanged at 70 to'provide a seat for the elbow and if desired the elbow may be provided with an external flange bear ng on the upper end of the member 68. The lower end or the member 68 is externally taper-threaded and is cut in the threaded portion into a plurality of tongues 71 embraced by a not 7 2 on the threadcd portion, At one point in the circumference. of the threaded portion two of the adj acenttongues are separated by a comparatively wideslot 73. The lower portion of the vertical section is composed of-atube 74 entering the lowerpart of the member 68 and retained by screwing the nut 72 up over the tapered thread to contract the lingers 71 around the tube. 'lhis'arrangement consti-I tutesa chuck. The tube 74 may be provided at one point in its circumference with an outwardly extending pin or lug 73 adapted to enter the slot 73 to positively hold the tube cutaway bel'owits horizontal diameter for a suitable distance, as shown at 77, Figures 1 and 6. A trough or chute 78, semi-circular in cross section, is slidably mounted upon the tube 76. so as to replace when neces-': sarythe cut-away portion of the tube or :to be drawn up on the tube. This chute is supported by means of rollers. 7 9 connected thereto and running on rails extending substantially. thefull length of the tube? 6 above its horizontal diameter. 1

'A'spider- 81. is mounted on thelower surface of the plate v32 adjacent, the vertical conduit section 49 and carries a still depending post 82, to thelower end of which an arm 83 is coimectedwitli means'i'or vertical adjustment and removal'over the lower end of the post. i The l'ree extremity of this arm .is bored to receive a steady pin adjustably mounted in a lug 85 dependingfrom the elbow 53, the pin being disposed co-axially with the vertical conduitsection 4L9; This a ainst rotation within the member 68. The

ta, i

steady pin serves to hold-the vertical section 49 against displacement from its vertical position by the weight of the laterally extending lowersection 50 and serves also to relieve the ball bearing 75' of unequal loading- If the pin 84 becomes wornyit may be readily replacedwithout disturbing any of the adjustments of the conduit. The steady arm 83 should be adjusted so as to be out of contact with the lug 85, as it is not desirable I mounted on the shaft 89.

nected by Initre V 88 with a horizontal shaft 89 mounted in gear s provided. A pinion 8'? is mounted axially vertical. on the plate 39 and meshes with the internal gear 86, so that as the plate 32 is rotated by the worm 41 the pinion 87 will travel arouiiid the internal gear and be thereby rotated. The pinion 87 is conor other suitable means ljearings 90 on the plate. A pair o'fi vertical posts 01 are rigidly secured to the platetifl and-rotatal'ily support a pair of: worm wheels 92, each of which mesheswith a worm 93 The hubs of the worm wheels carry above the wheels, flanges 9 1 to which complementary cams 95 and 96 are removably and adjustably secured. A

l circularly curved rack or quadrant 97 is provided lLO'DlGSll with the rotating pinion 69 of the vertical conduit section l9 and is supported by an arm 98 rotatably mounted on the post 5 1- helow the clevis 55. This quadrant arm .98 lies above the cains and carries on its lower surface a rotatably mounted roller or tracer wheel 99 engaged between the cams.

The profiles or outlines ofthe cams are such thatlthe roller 99 is not allowed any free play but is constantly in engagement with both cams each cam serving to hold the roller against the other cam.1 The out 1 e of the cams is specially designed to ,ause the arm to oscillate at a varying speed. To enahle this, the profile of one cam retreats rapidly from the po .1; of inax'zmiun radius, as at 100, so that for a small angular movement of the cam the arm will receive considerable oscill y movement. point of raj Jlfl recession starts om the maximum radius of the cam itiollows that the rapid movement of the arm will take place immediately or before change of direct on in the osc ll inent shown, in'unediately after such oi. direction. The profile ot the cam from the rapid recession to the point o'l" minimum radius or the cam is a smooth curve, so that the rcmainc oi the oscillation of the arm one direction will he at a substantially uniform speed. On the otherside o1 thelong diameter of the cam the curvature is smooth between the points of minimum and maximum radius, so that the arm will be caused to travel at a substantially uni form speed; The profile of the cam 95 is such as to cause the roller to follow the shaft rotation 100 of the cam 96. In other words,wh1le the. roller is following the sharply receding As this on of the arm; in the.

side of the cam 96, the cam 95 is the driving cam; while when the roller is following the'opposite side of the cam 96', this cam d.,.rivi1'1gand the cam 05 serves merely to hold the roller against movement away from the cam 96. Tie wormsv 93 are shown as right and left hand, so that the cams will rotate in opposite directions. This arrange ment is not-essential, as both vorms may he pitched in the same direction and the same result obtained by inverting one of thecams.

"lheoscillatory moven'ient imparted tot-he arm 98 and the length of the rack 97 hear such relation to the pinion 69 that thesanie is rotated alternately in opposite di ections through an angle of approximately.180" so that the lower inclined section of the conduit may he swung from a position diametrically under the plate 32 to a position ex:- tending radially therebeyond, as shown in Figure 1. The adjustment of the parts is such that the greatest speed of arm" oscillation, and therefore of rota ion ofthe vertical conduit section 1-9, occurs when the lower inclined section comn'iences to swine,- from 103 and 104:, being [guided around the bend I or" the elbow 53 by idl mounted on the elbow and positioned to ensure the lower half of the chain on the inclined section trav lling parallel with the of the section; A lug 107 is mounted on we trougn or chute 78 to engage in the cl'iain and impart movement of the chain to the chute to reciprocate the same upon the lower inclined section as the same swings from its inner to its outer positions. The speed of movement of the chute will have the same er rolls 10G :rotatably characteristicvariations as tl e speed of rotation of the vertical conduit Section' lS, since it derives-its movement from the rotation o'li'the conduit section carrying the pinion 102 around the rack 101.

v the kier.

The operation of the piling mechanism is as follows ;The lower section of the conduit being disposed diametricallyunder the frame as shown in full lines Figure l, the deviceis lowered onto a kier mouth and rests securely thereon by reason of the ribs 31 concentrating the load and avoiding creepage. If the upper section 47 of theconduit has been removed owing to lack of head room between the kier and track 12, this section is set and secured in place. The flushing ring is then set on the top of the conduit section 47. One orv more ends of cloth in rope form is or are fed into the upper end of the conduit and through the various sections thereof until the end emerges from the lower sectionand depends from the lower end of the trough or chute .78 into the kieiiz, it will be seen that the cloth depends ad jacent but not quite at the vcontralaxis of Threading of the cloth through the conduit may be facilitated by establishing a stream of water or other liquid through the conduit. When the piling is commenced thecloth is fed to the conduit at high lineal speed by means of a wince or other suitable apparatus. Water or preferably bleach liquid or otherliquid with which it is desired to impregnate the cloth is supplied through the pipe to the hollow ring (30 and escapes from the ring in a plurality of jets or streams directed downwardly and toward the axis of the upper condultsection 47. These streams of liquid impinge on the cloth in the upper section and thoroughly saturate the same so that the cloth loaded to many times its-natural weight, and by reason of this loading and by reason of the lubrication resulting from unobstructed liquid .tlow through the conduit the cloth passes through the'conduit at high lineal speed. The weight of saturated cloth, hanging from the lower end of the conduit will also serve to draw the cloth through the corn duit. Theoretically, the cloth will pass through the conduit at approximately the same speed that the liquid flowsthrough.

lVhile it may in some instances be preferable, it is not ordinarily essential to supply the liquid under any pressure greater than that necessary to ensure its delivery into the conduit, and it will therefore be understood' that the invention is not limited to the means for delivering the liquid in a multiplicity of jets, as in many instances the delivery of a sin ple stream into the upper end of the condi will sufiice to transport and lubricate the cloth and also to impregnate the same. As it is not necessary for tho'cloth to be touched by operators during the piling and is in fact completely guarded from such handlin it is aossible to emolo li uid heated nearly. to the boiling point. desired excess of liquid over that necessary for complete saturation of the cloth may be used up tothe capacity of the conduit and any excess of liquid accumulating in the kier may be drawn oil? inv the usual andwell known manner. 7

Before or as soon as the cloth starts feeding through the conduit, the motor 46 is started to rotate the worm ll which drives the plate orwo an gear 32. This plate carries the suture conduit and because of the I rotation of the plate, theupper vertical sec tion 47 of the conduit rotates about its own axiswhile the flushing ring 60 remains stationaryl; The intermediate vertical portion of the conduittravels in a circular path or orbit; that is to say, it and the inclinedconduit sections above and below revolve about the centreof the plate 32. As the platero lowcrinciined section swings through an arc' of approxin' ately 180, the swinging taking place simultaneously with the revolution of "the conduit. As the vertical conduit section 49 'rotatesaboutits own axis, it carries the pinion 102 along the circularly curved rack, sothat the pinion is rotated and rotates the sprocket 103 over which the endless chain 105 runs. Since the conduit section rotates alternately in opposite directions, the chain will be moved alternately in opposite directions and will cause reciprocation of they trough or chute ?8 on the inclined section 70, so as to move the delivery point of the cloth in and outon the conduit as it swings and revolves. The relation of the .p'inionand rack is such that the-chute 78 moves out as the conduit swingsout to the radial posit-ion shown in broken lines, Figure 1, and also 1.11 detail in Figure 6, and draws up on the con "duit as it swings into position under the plate 32. Owing to the bottom of the conduit section 76 bein cut awa at its outer end this movement of. the chute shifts the tie livery point of the cloth in and out in. length of the conduit section and has the same effect as lengthening or'shortening the conduit. includingthe sliding chute member 78 may be regarded as a conduit of length. I f v The ratio of gearing between the internal gear 86 andthe conduit rotating pinion 69 the In fact-,the lower conduit section changeable i spoof relation is that the whole conduit wii is such that the angular speed of the vertical conduit section about its own axis is n (in revolve several til. while the lower section swings out once from the centre to the Cl} cuniference of the hier. The result is that the delivery end of the conduit will trace a roug ly spiral path from the centre to the wall of the lrier. The profiles of the earns 95 and 96am such that the-swing of the conduit lower section is more rapid when it first commences to move away from the lrier centre than during the latter part of the swing. This variation in speed causes the path traced to depart somewhat from a true spiral in that the inner turns are spaced farther apart than the outer turns. The profiles the cams furthercause the con- .duit to swing inwardly at a slightly different speed than during its outward swing, so that it does not exactly retrace its path. Preferably the speed of swing increases toward the co tre of the lrier.

The roped cloth feeds through the conduit at a lineal speed in excess of the greatest lineal speed of the conduit discharge end and preferably vmore than twice the lineal speed of the conduit discharge end. Tie result that the cloth is laid in the kier not in a single smoothly curved strand but in a mound or ridge under and following ezo actly the path traced by the conduit discharge end. The plate 32 rotates at constant speed and therefore, disregarding any variation caused by independent movement of the conduit itself, the discharge end of the conduit will travel at higher lineal. speed atv the wall of the kier than adjacent "the centre, due solely to toe difference in distance' from the centre of revolution. The cloth feeds through the conouit at a uniform lineal speed and. it therefore follows that thepilo or ridge of cloth deposited will increase in size from the wall toward the centre of the kier. This increase in the size of the cloth pile toward the centre is compo sated for by the variable speed of saving of the conduit to space the turns of its path farther apart-toward the centre of the kier. When a layer of cloth has been deposited in the kier, it has the appearance of being somewhat higher at the centre and the spiral inound is more clearly defined. lVhen, however, succeeding layers are deposited, the weight flattens out the higher inounding toward the centre of the kier, this flattening being possible on account of the greater spacing in the turns of the spiral, providing room into which the piled-up cloth may flow, in the radial direction of the kier. Near the wall of the kier where the pile or mound is low, the turns of the spiral are closely arranged and there is subthe vertical plane thereof whereby the stantially no space for radial movement of the cloth when under pressure. The net result is that each layer of cloth, while irregular in thickness when first deposited, virtually resolves itself into a layer of uni form thickness. As already stated, the conduit is so arranged that it nevr piles.

exactly at the centre of the kier and inthis way any piling-up in the centre of the lzier is definitely prevented, so that the cloth piles level from the bottom to-top of'ihe kier.

When the kier has been piled as full as possible without obstructing the movement of the condi'lit, the motor is stopped, the cloth rope severed and the end allowed to slip through the piler, the flushing ring 60 lifted off the upper end of the conduit and the piling mechanismraised froin the kier to permit scaling thereof. Before stopping the motor, he operator ascertains that the conduit is swung inner position where it will not catch on the shoulder of the kier during removal. The position of the conduit indicated by the gong 112, which rings every time the conduit is swung fully under the machine.

l Vhile the preferred embodiment of the invention has been described and. illustrated, it must be understood that the invention is not confined to the details of construction, as numerous variations may be made without leparting froin thespirit the invention; for example, the internal gear 86, the teeth of which are parallel with the vertical axis of the machinc, may be replaced by a gear with teeth out radially of the machine,

in which case the pinion 87 will be disposed in a vertical plane and niay be connected directly to the shaft 89, thus eliminating the mitre gears 88. It will also be'understood that by changing t 1c gear ratios, the discharge end of the conduit may be causcr to travel in a path other than the spiral path described.
