To all whom it may concern:

Be it known that I, HOWARD D. CoLMAN, a citizen of the United States, residing at Rockford, in the count of Winnebago and State of Illinois, have invented certain new and useful Improvements in Textile Apparatus, of which the following is a specification.

This invention relates to winders or spoolers, and particularly to the operations of 1 replacing em ty bobbins with full bobbins, and full spoo s or cheeses with empty spools or cheese-cores. Heretofore it has been customary to place supplies of full bobbins and of labor necessary the operations empty spools or cheese-cores at points adjacent to the spoolenor winder, the opera-,

tives going to these sources of supply whenever necessar and, the full spools or cheeses have een carried away from the spooler or winder and deposited in suitable receptacles for transportation to the warper creels. This manner of supplying material to the winder and disposing of the product has necessitated a great many movements on the part of the operatives, with consequent expenditure of time and strength, and the frequent handling and re-handllng of bobbins and cheeses.

The object of this invention, generally stated, is to reduce to a minimum the amount in the performance of replacin bobbins and cheeses on winders and spoo ers, by providing means whereby the operative has constantly at hand a supply of the articles needed in the performance of her duties, and whereby the operative may move to various points along the winder with as little exertion and loss of time as possible.

The invention also contemplates a reduction in the number of handlings to which the spools or cheeses are subjected, by providing the winder operative with receptacles or supports for the full spools or cheeses,' which receptacles 0r supports are of such character thatthey may be transported to and. used in the 'creels of the warpers with the least possible handling of the spools or cheeses.

In the accompanying drawm s, Figure 1 is an irmer side view of a true comprised in an embodiment of my invention. Fi 2 isa top plan view of said truck, toget er with a portion of a winder or spooler in con- Specification of Letters Patent.

Fig. 4 is a sectional view of a vertically ad ustable platform or table intended to support bobbin boxes. Fig. 5 is. a fragmental v ew of the winder. Big. 6 is a view of the left-hand end of the truck. Figs. 7 and 8 are fragmental views, illustratin the construction and operation of the prope lin means for the truck. Fig. 9 is a fra enta sectional view of the means for raising and lowering the bobbin box platform. Figs. 10

' and 11 are views of a portion of the means for supporting the operatives seat.

The truck hereinbefore referred to is ar.- ranged for movementupon rails 1 placed alongside the spooler or winder, and is arranged to support the operative, a supply of full bobbins, a supply of cheese-cores, a receptacle for full. cheeses, and a receptacle for bobbins which, on account of some defect, cannot be unwound onsaid winder. The truck is provided with pedal-actuated propelhng means, in order that the operative may, with little exertion, move herself and the articles she needs in performin her duties, to any point along'one side 0% the winder. A similar truck 1s provided at the opposite side of the winder. he truck may be used in connection with spoolers or winders of the ordinary or any preferred type. Herein I have indicated portions of an automatic winder. The numeans maybe term (1 a winder-unit, each side of the winder consisting of a considerable number of such units. I

The winder comprises an automatic mechanism (not herein shown) which is arranged to travel in an endless circuit, so as to op crate in succession upon the units forming the two sides of the winder, said mechanism acting to tie the end of .the thread on the reserve .bobbin to the end of the thread on the cheese. Thespeed of winding and the time consumed by the uniting mechahism in making one complete circuit of the winder are so proportioned to one'another that the unwinding ofeach bobbin will be completed just prior to the arrival of the uniting mechanism into operative relatlon to the respective bobbins. In practice,'tl 1eoperative, seated upon the truck herein shown, follows the uniting mechanism, re-,

placing the exhausted bobbins with reserve bobbins, and replacing the cheeses, .when full, with empty cheese-cores. It may be here stated that the cheeses are never wholly unwound in the warper. When empty cheese cores are herein mentioned, it will e understood that the cores are only relat1vely empty.

In the winder framework is arranged, at a suitable height, a shelf or platform 5 (hlg. 3)'to receive boxes containing full bobbins. Preferably these boxes are t o'se employed with portable spinning-frame dofiers, such a box, for exam le, as is. shown in patent No. 983,858. erein the boxes are indicated at 6." They may be transported directly from the spinning room to the shelf 5 and arranged thereon in two rOWs extending longitudinally of the winder, as-represented in the drawings. Boxes 7 to receive empty bobbins are placed upon the floor beneath the shelf 5.

The truck may be of any suitable construction. Herein ll have shown it as comprising a rigid frame 8 supported .on the axles 9 and 10, said axles having wheels 11 mounted thereon. The wheels are adapted to roll upon the rails 1. A

12 is a seat for the operative, said seat being fixed to an arm 13 having a sleeve portion 14 (Fig. 11) which is rotatably mounted upon a pivot 15 fixed to a standard 16 rising from the frame 8. The sleeve 14 is supported at the desired height by means of a collar 17 which is vertically adjustable on the pivot 15 but is held against rotation by a key 18. A set screw 19 provides means for securing the collar 17 in adjusted pos1- tion. In order toreleasably hold the seat 12 in operative position, the sleeve 14 is provided with a beveled rib 20 and the collar 17 with a similarly formed groove 21 to receive the rib when the seat is in operative position. I

Fixed to the arm 13 is a horizontal arm 22 which normally extends inwardly and has fixed to its inner end a pad. 23.

The seat 12 is supported to swing upon the axis .of the pivot 15 in order to enable the operative to enter and leave the truck conveniently. Assuming the seat 12 and the pad 23 to occupy the positions shown in dotted lines in Fig. 2, the operative steps upon the truck and swings the seat into operative position by pressing against the pad.

The means for propelling the truck may be of any suitable character. Herein ll have rections.

hea ers shown two pedals 24 and 25 located in operative relation to the seat, and fixed u on rock shafts 26 and 27, respectively. T ese rock shafts are mounted in bearings on the frame 8 and extend longitudinally thereof. On the shaft 26 is fixed a bevel gear segment 28 (Figs. 6 and 7).that meshes with a' similar segment 29 rotatably mounted upon the axle 10. To the segment 29 is fixed a. crank arm 30 to which is pivoted a pawl 31 arranged to engaie a ratchet wheel 32 fixed on the axle 10. .7 spring 33 tends to move the pawl into engagement with the ratchet wheel. A spring 34 anchored at one end to the frame 8 and attached at its other end to a crank arm 35 fixed on the rock shaft 26 tends to hold the pedal 24 innor- ,mal position. 36 is a pin fixed in the pawl dicated in the drawings by the same numerals with exponents added. The two ratchet mechanisms operate in opposite di- A shaft 40- hereinafter described serves as a stop to limit the active movementof the pedal 25. Both pedals have approximately the same range of movement.

In following the uniting mechanism, the operative movesv the truck to the right by operatmg the pedal 24, the extent of movement imparted to the truck by one depression of the pedal 24 being approximately the same as the distance between two adjacent winder-units. Tn returning to the startlng point, the operative uses the pedal 25, the gearmg 28 and 29 being such that the return movement may be accomplished with fewer strokes of the pedal than are necessary in the working trip.

At the point upon the truck which is convenient to the right-hand of the operative is a chute 41 for conducting empty bobbins to the boxes 7. 42 is a guard plate fixed 1n proper relation to the receivm end ofthe chute 41 to stop bobbins tosse against said plate by the operative, and insure that such bobbins shall pass into the chute. To

prevent bobbins from sliding out of the chute into the spaces between the boxes 7 ll place upon the frame members 2 between said-boxes stop members 43 (Fig. 5) which extend across the space between two adjacent boxes and close the end of the chute whlle the latter is traveling from one box to the next. The ends of the stop members. 43 are made wedging so as to cam up and release any bobbin that might become 'caught between a side wall of the chute and the end of the stop member.

'Means' for supportin a supply of full bobbins is provided at t e left-hand side of the seat 12. Said means comprises, in this instance, a revoluble platform 44;. This platform is adapted to support two bobbin oxes 6, the platform being made rotatable stooping to pick up bobbins.

In the construction .herein shown, the platform 44 is fixed to a lunger 45 (Fig.4) which is rotatable and s idable in a cylinder 46 secured in a vertical position upon the frame 8. When in its lowermost position, the top of the platform 44 is in the horizontal plane of the top of the shelf 5, so that the operative mayreadily push an empty box 6 olf said platform onto the shelf 5 and pull a full box 0d the shelf onto the platform.

The platform 44 may be raised by means of a ump 47 (Fig. 9) arranged to force a suitable liquid into the cylinder 46. Said pump comprises a cylinder 48 having an inlet and outlet port 49, and a piston 50, the rod 51 of which is connected to a pedal 52. The suction movements of the piston are imparted to it by a spring 53. Oommunicating with the port 49 is a checkvalve-controlled inlet 54 located within a reservoir 55. A line of pipe 56 extends between the port 49 and the lowerend of the cylinder 46, said line of pipe including a check valve 57. When the piston is forced downwardly, the oil or other liquid is forced from the cylinder 47 into the pipe '55, past the check valve 57 and to the cylinder '46, thereby raisin the plunger 45 some distance in the cylin or 46. The platform 44 may thus be gpadually raised by the'operative in order to keep a supply of bobbins close at'hand. At a point in the cylinder 46 determining the upper limit of movementof the platform is an outlet port 58 com- 'municating with a return-flow pipe 59, said pipe leading to the reservoir 55. Included in the line of pipe 59 is a pressure-relief chamber 60 to allow the liquid to escape quickly through the port 58 when said port is opened by the rising of the plunger 45. 60 is an air vent hole in the top of the reservoir 60.

To permit of lowerin the platform 44 I provide a discharge va ve 61' in the pipe 56 within the reservoir 55, said valve being operable by means of a. pedal 62 fixed to the shaft 40, said shaft being connected throu h a crank arm 63 and-link 64 to one arm of a rality of warper-creel elements.

7 bellcrank lever '65, the other arm of said lever bearing against the stem of the valve 61. A s rin 66 normally holds the valve 61 closed position.

Oil leaking up along the plunger 45 is conducted to the return-flow pipe 59 b an annular groove 67 in the upper end 0 the cylinder, av duct 68 and a pipe 69. Any oil that may leak up past the iston 50 is returned to the reservoir 55 t rough the annular space 70 and duct 71.

At the right-hand side of the seat 12 is means to support the cheeses removed from the winder. Said supporting means consists of a revolubleplatform or table 72 supported at a convenient height uponthe truck.

an holds the pedal 62 in initials The platform 72 is adapted to support a plu- The form of creel element herein shown may be termed a trident and consists of a base a to which are attached three spindles, each spindle having four bushings or sleeves b rotatably mounted thereon. The cheese-cores are adapted to be slipped over said sleeves. The tridents are removed from the warper creels, with the empty cheese-cores remaining in position thereon, and placed upon a table 73 located at the ri ht-hand endof the path of movement 0 the truck. Thetop of the table 73 is in the horizontal plane of the top of the platform 72. The side of the table 73 facing the truck is recessed as at 73 (Fig. 1), to conform to approximately one-half of the periphery of the platform 72, so that when said platform is placed against the table" the operative. can push filled tridents onto the table and pull empty tridents off the table and onto the platform.

A box 74 is removably supported on the truck beneath the platform 72, said box being intendedto receive bobbins which cannot be unwound on the winder. The box stands upon two bars 75, and may be inser'ted and removed from the front (or outer) side of the truck.

In practice, the operative follows the uniting mechanism, removing the spent bobbin from the bobbin-holder of each winder-unit, tossing said bobbins into the chute 41, taking full bobbins froma box 6 on the platform 44, placing said full bobbins in the bobbin-holders previously occupied by spent bobbins, and placing .the ends of the yarn on said full'bobbins in position for action thereon by the uniting mechanism on its next visit. The operative also removes from the winder any cheeses that may be full or complete, placing such cheeses onto a spindle of a trident, taking empty cheese-cores ofi another trident-spindle, and placing such empty cheese-cores upon the winder-units from which the full cheeses were removed.

It will be seen that this invention provides means for greatly economizing the time of ios winder operatives, thus rendering it possible for an operative to care for a greater numllgier of units than would otherwise be possie. v I By minimi ing the amount of handling to which the cheeses are subjected the invention not only saves labor, but also obviates I .thedanger of damage to the cheeses resulting from the previous methods of handling and piling. i I ll claim as my invention: f
