(ci. 51-1s) 1 Claim.
This invention relates to improvements in fliers for wrapping yarn around wire to provide a covering for insulation or other purposes.
Generally, apparatus used for wrapping yarn around wire includes a basket or cage in which the yarn cop is disposed and more or less concealed from view. Such arrangement necessitates frequent inspection of each unit individually by the operator in order to apprehend exhaustion of the supply of Ayarn as it is drawn from the cops.
An object of the present invention is to provide a Iller so constructed that when a group of similar fliers are arranged to be operated concurrently under management of a single operator, the depletion ofthe yarn,l as it is withdrawn from the various cops, is readily detected by the operator when replenishment with new cops is required.
Another object of the invention is to provide a flier from which yarn is withdrawn from the cop and wrapped around a wire, so constituted as to be fully exposed to observation during operation thereof wherefore to enable the operator to readily ascertain the progress of depletion of the various cops during withdrawal of the yarn therefrom.
Other objects and advantages of the invention appear in the following description.
An illustrative embodiment of the invention l is shown in the accompanying drawing, in which:
Fig. 1 is a top plan view of a structure in which the invention is incorporated;
Fig. 2 is a side elevational view projected from` Fig. 1, a portion thereof being broken away;
Fig. 3 is a side elevationalview of a cop supporting post, a portion thereof being broken away;
Fig. 4 is a top plan view projected from Fig. 3;
Fig. 5 is a too plan view of a, friction plate used in the structure;
Fig. 6 is a side elevational view projected from Fig. 5, partially in section; and
Fig. '7 is a plan view of a friction pad forming part of the structure.
The illustrative embodiment of the invention consists of a hollow spindle 8 mounted for rotation upon its axis and driven by any suitable mechanical means (not shown). The spindle has secured concentrically thereon a bed-plate 9 having an upstandina yarn-receiving post I0 the axis of which is disposed parallel with that of the spindle, and an upstanding guide-supporting post II to which are secured an intermediate guidehook I2 and a top guide-hook I3, said posts being I located on said bed-plate at points adjacent each other and near the outer periphery thereof.
In the top of the spindle 8 is secured, by means of a collar Il, a nose piece I5 of a. type commonly used on iiiers through which the wire I6 passes as it travels upwardly through the bore of the spindle 3. A tubular cop-post I1, provided with radial external ribs I8 and a flange I9 on its lower end, is mounted on said spindle loosely to permit free relative axial and angular movement thereon, the lower end of the post having a recess 20 therein, and a friction disk 2i is iirmly secured in the post, there being .a sleeve 22 projecting upwardly from the disk that is pressed into the recess.
A circular cushion 23, preferably made of hard felt and provided with a central, opening 24, is positioned on the bed-plate 9 and surrounds the spindle, and the friction disk 2| rests upon the cushion so that upon rotation of the bed-plate rotary movement is imparted to the cop-post I1 through the medium of the cushion.`
In use, the wire I6 is projected up through the spindle and nose piece. and the free end of the yarn is uncoiled from the cop. strung around the yarn-receiving post, up through the intermediate guide-hook I2 and top guide-hook I3, and around the guide-pin I5 on the nose piecee the extending terminal portion 0i.' the yarn then being wrapped manually around the wire preliminary to operating the machine.
The wire is progressed at a predetermined rate of speed upwardly through the spindle and the nose piece by such ordinary means (not shown) as is common in the practice, and concurrently, the spindle together with the bed-plate is'rotated by any suitable motion-transmitting mechanism (not shown). Thus, as the wire is progressed the yarn becomes wrapped spirally around the wire form of a cop 26 which is provided in the usual manner, the 4 while it is unwound from the cop which accom modatingly turns together with the post and friction disk under restraint oi' friction developed between the disk and cushion. i
To insure stability of the rotating parts about the axis of the spindle, a weight is secured to the bed-plate consisting oi' a spindle nut 28 threaded on a stud 29 that projects from the bed-plate together with one or more washers 30 of selected weights, wherefore to counterbalance the Weight oi the receiving and guid-posts oppositely located on the bed-plate, and to compensate for the drag of the yarn as it is pulledaround the receiving post and through the guides into the nose piece. A feature of the invention is the arrangement by which the frictional resistance to the progressive rotation oi' the cop and its supporting post is automatically reduced as the load of yarn on the cop diminishes while the yarn is withdrawn therefrom because of the consequent reduction in weight of the cop. By this means the tension of the yarn as it is fed to and wrapped around the Wire is substantially constant, resultingin uniformity of the covering of yarn wrapped around the wire.
Variations from the particular construction above disclosed may be resorted to'by the exer- Ivided at its lower end with a friction disk, a
cushion encompassing the spindle interposed between the bed-plate and disk upon which the assembled cop post, disk and a yarn cop disposed on the cop post rests, and is frictionally engaged thereby, an upright yam-receiving post on said bed-plate the axis of which is parallel with that of the spindle, an upright guide-supporting post, said yarn receiving and guide-supporting posts being located adjacent each other near the perimeter of said bed-plate and guides on said supporting post, the arrangement being such as to direct travel of yarn withdrawn from said cop as it is fed to a wire passing up through the spindle and nose piece to be wound thereon.
