JOHN HENRY SCOTT, OF NOTTINGHAM, ENGLAND.

SPECIFICATION forming part of Letters Patent NO. 742,913, dated November 3, 1903.

Application filed November 13, 1902. Serial No. 131,262. (No model.)

To all whom it may concern.-

-Be it known that 1, JOHN HENRY SCOTT, engineer, a subject of the King of Great Britain, residing at The Standard "Works, Dame Agnes street, Nottingham, England, have invented certain new and useful Improvements in Machines for Covering Vires, Cords, and the Like, of which the following is a specification.

This invention relates to improvements in machines for covering wires, cords, and the like.

The chief object of the invention is to apply to any desired core at a very high speed one or more lappings or coverings, which may be wound in the same or in opposite directions, the core consisting either of a wire or wires, a cord or cords, or of a number of longitudinal yarns, strands, or warps held together by the lapping or covering.

Referring to the accompanying drawings, Figure 1 is a front View of themachine. Fig. 2 is a side view thereof, partly in section, Fig. 3 is a side view with certain parts removed looking toward the right of Fig. 1. Fig. 4 is a plan of Fig. 3. Fig. 5 is a detail view.

A is the main frame of the machine, which has a base-plate B, carrying a bracket 0, in which the main driving-shaft D is mounted, this being driven by fast and loose pulleys E E, provided with a belt-shifter fork E Beneath the base-plate B are brackets F, carrying the drum G for the wire Hwhich is to be covered. This drum has a grooved pulley G, over which a weighted brake-cord I passes for keeping a strain on the wire. Beneath the machine is arranged a group of bobbins J, from which the yarns k are drawn through perforated guide-plates L and M, so that they are brought together evenly and meet at a point in the guide N, together with the wire, and lie straight along the latter all around it. The wire then with this preliminary covering of longitudinal yarns or strands passes up through the revolving wrapping devices, about to be described, and is finally wound upon a drum 0 at the top of the machine.

The yarns which are to be wound or wrapped around the wire are designated by the letters a a and are fed from bobbins b b, provided with light revolving arms or fliers c c, Fig. 5.

The wire or core passes centrally or axially through the bobbins b b, which are arranged one after the other, as shown-that is, in series. These fliers have suitable guide-eyes 0 for their yarns and have holes or sockets c at their ends to fit over the tapered ends of the parts (1 on which they revolve, the parts 01 being hollow nozzles through which the wire passes. The fliers c are also provided near their middle with a localizing or guiding device 0 comprising a small block, having at its ends a'pairofperforated lugs 0 through which the wire passes. The lugs are situated close together, and the lapping-yarn a or a is fed from the side through a guide-eye 0 into the space between the lugs, so that it is guided right upthe wire, and the lugs serve to localize the lapping and keep it even, so preventing the winding getting out of place or working its way to the wrong part of the wire.

The wire His fed from the drum G, together with a suitable number of yarns K, from the bobbins J, and through the suitably-perforated plates (termed slay-plates LM. After going through the bobbins b b and the lapping or winding devices it passes to a takeup device, comprising a number of differentsized pulleys e, and passes over and about one or other of these, according to the speed desired, being finally wound on the receiving drum 0, which is in driving connection with the pulleys e by a belt or cord 6, which is passed around a tightening or jockey pulley e carried by a weighted arm 6 The shaft of the take-up pulleys e is actuated from the main driving shaft D, which also works the spindles carrying the lapping bobbins and fliers. The driving connection is efiected by an intermediate shaft f, geared with the driving-shaft D and take-up shaft 6 by helical gear-wheels f f This shaft f is carried by bearings f adjustable in slots 4 in the frame, so that it can be shifted slightly to allow of the gear being changed.

In connection with the receiving-drum isa traversing guide-fork g, designed to insure the even and regular winding up of the finished work. This fork is operated from one end by a spring-lever g, pivoted at its lower end and at its upper end provided with a yoke g, which engages a pin or projection on the endwise-movable rod 9 on which the fork is mounted. A spring g is arranged to move pulleys b on the main driving-shaft D, suitable tightening-pulleys 19 being provided to enable the belt to be kept as tight as necessary. As shown, the band I) simply passes over and under one of the pulleys b While it is crossed and passes completely around the otherpulley.

The bobbins and their associated parts are;

supported by brackets 71, carried on a central stem or pillar h, Fig. 2.

At the bottom of the machine are a set of small pulleys H, over which the wire H is drawn to take out any small bends or irregularities, While on the top bracket 71 is a small pulley h for guiding the covered Wire on to the pulleys c. The wire H passing up into the machine with its accompanying yarns K, forming a longitudinal layer or sheathing, around it, receives from the lower bobbin 1) and flier c a winding in one direction and. from Z) and c awinding in the opposite direction which effectually bind the longitudinal strands on to the Wire and form themselves into a smooth and regular covering for the whole.

The finished work is wound up on the drum 0 in a regular and even manner ready for removal.

Obviously the invention is not limited to any particular shapes, sizes, or materials, those indicated in the drawings being merely by way of example.

What I claim, and desire to secure by Letters Patent of the United States, is-

1. In a machine for covering wires, cords and like articles, the combination of revolving bobbins, fliers on said bobbins, a localizing device for each flier comprising perforated lugs arranged on said flier in proximity to one another for the passage of the wire or cord to be covered, and a guide-eye situated between said lugs for the passage of the yarn on to the article to be covered, substantially as described.

2. In a machine of the kind referred to the combination ofbobbins, fliers on said bobbins, localizing devices for controlling the wrapping, a roll from which the article to be covered is fed, a brake for retarding the movement of the roll, means for applying a preliminarycovering of straight longitudinal yarns thereto, perforated slay-plates for guiding said longitudinal yarns, a guide to which said yarns converge after leaving the slayplates, substantially as described.

In testimony whereof I have hereunto set my hand, in presence of two subscribing witnesses, this 31st day of October, 1902.

JOHN HENRY SCOTT.
