JOHN MCOAHEY, OF PROVIDENCE, RIIODE ISLAND, ASSIGNOR TO THE NEW ENGLAND BUTT COMPANY, OF SAME PLACE.
WIRE-COVERING MACHINE.
SPECIFICATION forming part of Letters Patent No. 455,970, dated July 14, 1891. Application filed September 12, 1890i Serial No. 364,768- (No model.)
To all whom it may concern:
Be it known that I, JOHN MOCAHEY, of Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in WVire-Covering Machines; and I do hereby declare that the following is a full, clear, and exact de- .scription'thereof,reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.
This invention relates to that class of wirecovering machines that use a central spool to hold the covering material, and is an improve- I 5 ment on the invention described in my United States Patent No. 439,67 5, in which the guide for supporting the wire andlaying the covering-strands properly thereon is made a part of the flier that conducts the strands from the serving-spool to the wire. Though the form of the groove for holding the wire and delivering the strands thereto and the posi tion of the flier in that case were far in advance of previous attainments in that class of 2 5 wire-coverers, still subsequent experiments prove that a guide held by the flier in that way must be subject to all the variations of that flier consequent to using the high speed indispensable to success in competition. The trouble caused by running the winder at high speed is mainly in the increased centrifugal action in throwing 06 the free end of the flier, to which the guide is attached,from the center line of the revolving mechanism. The lower 5 end of the flier being held in the plate and its'upper part brought over the spool in a curve, the effect of the centrifugal action in throwing it out is to raise the free end of the flier with the guide as the speed is increased and let it down back again when the speed is decreased, and this raising up of the guide causes the covering-strands to lap over one another, while the dropping back again leaves bare places on the wire. When we consider 5 that doubling the speed quadruples the centrifugal effect, it will be seen that bad effects increase very rapidly as the speed increases and magnify the irregularities in the speed of the driving-shaft. To obviate this objection, and also to secure'some other advantages, I place the guide in the end of the tube that holds the spool of covering material instead of on the end of the flier, so that the center of the wire as it lies in the guide is at all times in the exact center of rotation of the covering mechanism. I also obtain advan tages by this arrangement in regulating the friction or tension and direction of the covering-strands in covering wire of different sizes, as will be explained farther on.
In the accompanying drawings, Figure 1 is an elevation of that part of the wire-covering machine immediately connected with the improvement. Fig. 2 is an enlarged elevation of the end of the tube which carries the spool 6 5 of covering material and holds the guide and a part of the flier. Fig. 3 shows the same parts as Fig. 2, the guide having been changed in position. Fig. 4is the same as Fig. 3,.with a further change in the position of the guide. Fig. 5 shows a horizontal section of the guide, taken on the line 00, Fig. 2. Fig. 6 shows a similar section to Fig. 5 taken on line a; at, Fig. 4:- Fig. 7 is a representation of the guide b separate from the tube a.
The part of the winder shown in the drawings consists of a plate 6, revolving around a stationary tube a, made fast in the frame below. The plate 6 carries the spool d, holding the covering material, the flier-arm j, and
stud m. The wire ,2 to be covered is drawn through the tube a from a reel placed in the machine below; The flier jis not made fast in the plate e, but left free to be turned away from over the spool d when it is necessary to put on a full spool. The spring 0 on the flier has one end attached to the flier and the other end carried in to bear against the stud m, so as to hold the arm over the spool while in operation.
The parts of the machine other than those described here are constructed and operated as set forth in my United States Patent No.
445,598, dated February 3, 1891. The guide I) is a cylindrical piece of metal, the lower 5 part of which is fitted in a hole made in the upper end of the tube a, so that it can be easily turned in its place, and the hole is made deep enough to allow the guide to be set higher or lower with regard to the end of the tube a. I00
A set-screwk is fitted in one side of the tube a to screw in against the guide and hold it in any desired position, the slotted head of the set-screw being let in flush with the outside of the tube to allow a spool of the covering material to pass over it when necessary.
Alongitudinal groove 11. is made in the upper portion of the guide b, the groove extending fully to the center'of the guide or a little,
deeper, and a small holef, starting from the center of the lower end of the guide, comes out into the lower end of the groove mso that the wire .2, after passing up through this hole f, will continue in a direct line along the bottom of the groove n, where the covering-strands are wound on it, and thence up to the reel.
above referred to, No. 439,675.
groove, leaving a little of that side, about the height of the diameter of the wire, re
maining to support the wire against draft of the strands in covering. 'lhe recess sis inade slightly spiraling to agree with the di-' rection of the strands when Wound on the wire, and just aboutthe width of the-cover; ing-stran'ds when spread out close together side by side, in which positionthey pas -over the side of the groove left in the recess from I v g The 'p'o'sition of the guide I) in the end of the tube (1.
the end of the flier onto the wire.
admits of an exact adjustment of the tension on the covering-strandsas it is only-news The strandsof covering material reach the wire through a notch or recess 1 s in the side of the groove, as in my patent This recess? '5 is cut nearly down to the bottom of g the i 6 the friction 'of the strands is increased on the guide by making them pass farther around it, by which it will be readily seen that the tension on the strand can be increased as desired by turning the guide in one direction and reduced by turning it in the other direction. The angle at which the strands wind on a the wire differs from the angle when winding on a larger wire, and it is advantageous to adjust the direction of the strands from the flier to the wire to suit the size of the wire to be'covered. To accomplish this, the guide b is set higher or lower in the tube a by loosening the set-screw, as in the case of adjustment of the tension, and when properly adjusted by tightening the setscrew that position will be maintained. By thus placing the guide in the center of the spool-tube and having its center in line with the center of' revolu'tion of the covering parts of the machine it will be free from all the perturbations and changes of position which it would be liable to if attached to the flier,however much the speed may be increased, and the covering of the wire will be performed with greater regularity and rapidity. h v I Having thus described my improvements, I claim as my invention- V In a wire-covering machine, the combination of a central revolving tube and a guidetube lengthwise and axially adj ust-abl'e therein and provided near one end with a longitudinal V-shap'ed slot, and a transverse slot rectangular in cross-section communicating therewith, substantially as described.
