SPOOL-CARRIER FOR WINDING-MACHINES.
L-PECIFECATION forming part of Letters Patent No. 330,036,6iated November 10, 1885.
Application filed October 14, 1884. Serial No. 145,479. (No model.)
To all whom it may concern;
Be it known that I, J OHN McOAHEv, of Providence, in the county of Providence and State of Rhode Island, have invented certain 5 new and useful Improvements in Spool-Oarriers for Winding-Machines; and I do hereby declare that the following is afull, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form apart of this specification.
This invention relates to that class of machines used to cover wire for electric conductors, and for other purposes, constructed with r a horizontal disk or plate carrying a series of spools, and made fast on a vertical hollow shaft held in suitable bearings, through which hollow shaft the wire is drawn by a takeup motion common to braiding and winding machines, the revolutions of the shaft and plate winding the threads on the spools around the wire, and thus covering it. It is illustrated in the accompanying drawings, in which- Figure 1 shows a front elevation of a set of spool-carriers on the revolving plate of awinding-machine. Fig. 2isa top view of the same. Fig. 4 shows a top view of one of the carriers, and Fig. 3 is an elevation of the same.
D is the plate of a winding-machine, upon 50 which the spools a a, with their guides B and tension-regulating devices, are carried around the wire w, which passes up through the center of the plate in the process of being covered with the thread on the spools. The
3 5 plate D may receive its rotary motion in any of the usual modes adopted in such machines.
The carrier shown in Figs. 4 and 3 consists of a base-plate, B, whereby it is fastened to the plate D, a vertical spindle, a, on one end of the plate to hold the spool a, and a bar, B, at the other end to receive the weight A that slides up and down on it and rests on a bight of the thread i, between the guide-hole c in the middle of the bar and the guide 0 at the upper end of the bar. 7
In the usual way of constructing these carriers the bar B is placed in a vertical position and the weight A regulates the tension of the thread very well with the bar in a vertical position, so long as the speed of the plate is not carried beyond a certain degree; but when the speed is increased to the point that the other parts of the machine are capable of bearing the increased centrifugal force exerted upon the weight A causes it to press against theinside of the bar B, so as to prevent the weight from falling freely as it should to regulate the tension of the thread. This difficulty I entirely overcome by inclining the bars Bin toward the center of the circle Where the wire is, so that they will stand at an angle of about twenty-five degrees from their former vertical position, for when so placed the centrifugal force thrown upon the weights assists the force of gravitation sufficiently to overcome the 6 friction caused by the pressure of the weight against the bar, as above stated. As a rule, the speed of fifty-nine or sixty turns per minute will increase the centrifugal force sufficiently to overcome the force of gravitation, but by inclining the bars in this way a speed of five hundred turns per minute is found to be practicable, and have the Weight act as it should to regulate the tension of the thread. This position of the bars also produces other desirable results. It brings the upper guide end, 0, of the bars nearer to the point where the thread If is wound on the Wire and lays the coils of thread with greater regularity on the wire. It also brings the course of the thread between the guide 0 and the wire more directly in a line with the direction of the thread between that guide and the weight, thereby greatly facilitating the quick action of the weight by avoiding the friction in the guide caused by the change in the direction of the thread after passing through it. Inclining the bars also increases the distance between the guide-hole c and the spool a, which lessens the liability of the thread to draw off harder from the extreme ends of the spool than it does from the middle.
Alatch, b, for the purpose of holding the spool from turning by catching in the ratchetteeth a in the top of the spool, is pivoted in the top of the spool-spindle a and lies in such a direction that its free end shall be close to the weight-bar B, and the weight A, when raised by the thread to theposition shown'by the dottedlines in. Fig. 3, shall raise the latch b out of the teeth on the top of the spool and allow it to turn and let off a portion of the thread, the slack of which, passing into the bight holding the Weight, allows it to drop, and the latch b again drops into the teeth on the spool and holds it until the weight is again raised.
By operating the latch b by its long end a purchase is obtained over the resistance caused by the pressure of the spool against the latch, thereby equalizing the action of the weight and that of the thread as it is wound upon the wire.
The combination of the bar B, weight A,
Vertical spool-spindle a base-plate B, and plate D, the bar B being inclined inward toward the axis of rotation of the plate D, sub- 25 stantially as and for the purpose set forth.
