My invention relates to improvements in slasher machines and my invention resides particularly in the construction of the creel or stand which feeds the yarn to the sizing mechanism from which it is dried and delivered in condition for making the cloth or fabric.

One object of my invention is the provision of a creel which will feed or supply the strands of yarn to the sizing means under the proper tension to prevent breaking of the yarn and with the strands of. yarn in practically parallel relation to insure perfect sizing and drying of the yarn.

Another object of my invention is the provision of a creel or stand which may be used as a single unit, or in series and operated by one power unit to supply the yarn in a smooth and continuous manner without danger of breaking of the strands or threads of yarn.

Another object of my invention is the provision of a mechanism of the character and for the purpose stated which will insure the passage of the yarn from the creel under the proper tension and at the desired speed and in a manner to subject the entire body of the yarn to the action of the sizing means and not strain or break the strands of yarn during its travel through the machine.

Another object of my invention is the provision of. a creel or yarn tension and feeding mechanism for slasher machines which will be of simple, durable and inexpensive construction and which will prove efficient and practical in every particular.

With these objects in view my invention consists of a creel or yarn feeding and supplying mechanism for slasher machines embodying novel features of construction and combination of parts, substantially as described and defined and distinguished by the claims, and as shown in the accompanying drawings, in which:--

Figure 1 represents a side elevation of a complete slasher machine in which my improved creel is embodied and operates in conjunction with the sizing, drying and delivering means of said machine, to illustrate the relation of my creel to the other parts of a slasher machine of the usual type.

Figure 2 represents a side elevation of the creel or stand shown on an enlarged scale.

Figure 3 represents a sectional View on line 3--3 of. Figure 2.

Figures 4 and 5 represent detail views of the laterally adjustable slotted arms for supporting the drums.

Figure 6 represents a plan view of the creel with parts broken away to show details of construction.

Figure '7 represents an edge view of the train of gears between the slasher and creel.

Figure 8 represents a view on line 8-8 of Fig- 5 ure 1.

Figure 9 represents a view on line 9-4! of Figure 2, and

Figure 10 represents a detail sectional View of the driving drum and spools on beams carrying 10 the yarn to show the frictional action of the driving drum upon the series of yarn carrying drums or spools.

Referring by numeral to the drawings in which the same numerals denote like parts in all the 15 views:

The numeral I. designates the main frame of a slasher machine of usual type in which is rotatably mounted the large drying roller 2, and the smaller drying roller 3, which receive heat 20 from the pipe 4, toeffect the drying of. the yarn 5, in its passage through the machine as indicated by the arrows.

, Located along one side of the main frame is the power or driving shaft 6, carrying at its outer end the worm l, meshing with the wormwheel 8, which coacts with the yarn guiding wheel 9, to deliver the yarn to the roller It, from which the yarn is taken to produce the cloth or fabric.

The inner end of this power shaft 6 is mounted on a bearing I l of the frame l2, and has its inner end It extended to operate the sizing elements M in the size box I5, said extended end being journalled in a bracket or support [6,.secured to said size box.

On the extended end 13 of said power shaft is also mounted the upper gear Wheel 11, meshing with the intermediate movable or adjustable gear wheel I8, which in turn meshes with the lower gear wheel i9, as most clearly shown in the enlarged views, Figures 7 and 8.

The lower gear wheel I9 is mounted on the inner end 26 of the shaft 2|, which extends longitudinally along the lower sides of the frame 22 of, the stands or creels and bears in brackets 23, secured to said frame 22.

The machine is shown as being equipped with twin or a pair of stands or creels, but "it will be understood that a single or a series of creels may be used and when more than one creel is used, the creel driving shaft 2i is made in sections joined by a coupling 24, and the machine will operate in a practical manner using a single or a series of creels. v

The description thus far is clearly shown in the complete machine, Figure 1, but the main and essential structure of my invention is the creel or stand shown most clearly in Figures 2, 3, 4, 5, 6, 9 and 10, which views are on an enlarged scale to make the details of construction of the creel or stand perfectly clear, and this creel I will proceed to describe in full.

The creel or stand comprises the base rails 22, formed with the vertical central arm 22, and the radial or inclined arms 22", which arms are each formed with an angled portion 25, formed with a threaded depending lug 26, and resting upon said angled portion 25 is the foot 21 of the slotted arm 28, said foot having a depending threaded lug 21', and the threads of said angled portion 25 and foot 21 receive the adjusting screw 29 having a wheel or handle 30, for turning said screw and moving the slotted arm 28 in the ways 28 as shown in Figures 4 and 5 to widen the space between the arms 28 to permit easy operation or removal of the ball bearing mountings 3|, in the guides 32, of said arms 28.

From this construction it will be apparent that the slotted central and individual arms 28, are capable of being adjusted laterally or transversely and also that the ball bearing mountings are slidable in the slots of said arms 28, and thus the arms may be moved to increase the space or width between said arms and the ball bearing mountings have a sliding movement in the slots of said arms 28, the purpose of which will presently appear.

Passing through the ball bearing mounting in the three pairs of arms 28, are the shafts 33, each of which fits in the head ends or disks 34 of the spools or drums 35, upon which the load or warp of yarn 36, is wound, as most clearly shown in Figures 3 and 10. From this construction it will be noted that the set of three spools or drums are rotatably and, slidingly mounted in the slotted arms 28, with the charge or load of yarn 36 thereon, and as shown in Figures 3 and 10, this brings the surface or face of the load of yarn at all times in frictional contact with the driving roller 31, having its periphery covered with the transverse'slats 38, preferably made of wood, and in these slats are fitted the contact elements 39, preferably made of cork or like substance to insure their making a pliable frictional contact with the surface of the yarn to produce a properamount of friction to rotate the load under the desired'and necessary tension without risk of breaking the yarn.

This friction driving roller 31 is secured on the transverse shaft 40, mounted in ball bearings 4|, andhaving fixed to one end the large gear wheel 42, meshing with the worm 43, on driving shaft 2|.

The pair of inclined arms 28, are braced by the vertical rods or braces 44, and the braces 45 and 45', forming a strong frame structure, are inclined and form a spanner between the vertical center arms and the two pairs of inclined arms, and the apex of said braces is connected and secured by the angle shaped coupling member 46, connected by the rod 41, and also mounted in said couplings 46 is the ball bearing mountings 48, for the rotatable yarn guiding rod 49, allowing smooth and equalizing travel of the yarn.

It will be noted that the drums or spools which carry the load of yarn are mounted on shafts which have their ends extended to allow transverse movement of said drum's'in the ball bearing mountings to allow the bearings'to be moved.

Also the drums or spools which carry the load of yarn have a vertical movement in their bearings to accommodate the action of the drums in their relation to the friction driving drum.

From the foregoing description, taken in connection with the drawings, the operation of my creel or stand will be readily understood and it will be noted that the spools or drums with the charge or load of yarn are fitted in place in and between the vertical and inclined arms and the face or surface of the three loads of yarn pass or bear against the friction elements of the driving drum which when rotated causes the yarn to travel from the drums or spools through the sizing box or bath, thence to the action of the drying rollers and to the delivery or receiving rollers.

The advantages of my creel or stand will be readily understood and appreciated by all persons skilled in such machines and it will be evident that the yarn containing drums can be easily applied and removed; that the yarn is supplied under the proper tension and desired condition; that risk of breaking the yarn is prevented by the tension equalizing action of the machine; that the accommodating movement of the drums or spools and the frictional engagement of the v draining drums insures the complete unwinding of the yarns; that the creel will prove a great saving in time, labor and expense in the operation of the machine and that generally in every particular the invention will prove eflicient, useful and practical and meet every requirement of a machine of this character.
