UNITED STATES PATENT OFFICE.
I-IOXVARD PRIESTMAN, OF BRADFORD, COUNTY OF YORK, ENGLAND.
MACHINE FOR SPINNING, 840., YARNS.
SPECIFICATION forming part of Letters Patent No. 422,155, dated February 25, 1890.
Application filed February 13, 1889.
been granted in Great Britain, No. 16,115, 1
dated November 7, 1888,) of which the following is a specification.
My invention relates to that class of machines where caps are employed for spinning, twisting, and doubling yarns; and the object 1 of the invention is to so arrange the axis of the spindle that it shall stand aligned with the bite of the delivery-rollers, or nearly so, for reasons that will be hereinafter set forth, and to provide the spindle so arranged with mechanism for driving while in that position. In some of the machines for this purpose, where the spindles are provided with caps, the yarns, after leaving the front or delivery rollers, pass through an eyelet-board and thence to a bobbin or spool placed upon a vertical spindle or stud, and in practice it is found that a short length of yarn, after leaving the nip of the delivery-rollers, bears upon the periphery of the bottom roller,"and this in such machines arises in consequence of the yarn having to travel (during a part of its way to the bobbin) almost in a vertical line, consequently the length of yarn into which twist can be put is diminished by the length of that portion of the yarn resting upon the periphery of the said bottom roller. To obviate this I place the spindle or stud and bobbin at such an angle, or in such an oblique position in relation to the front rollers, as to prevent the yarn from bearing upon the upper surface of the bottom roller after the said yarn leaves the nip of the front or delivery feed-rollers, so that such yarn will be at liberty to take the twist immediately on leaving the nip and not after passing over or resting upon the bottom roller or eyeletboard, and in this manner by my invention twist can be put into the yarn throughout the whole length thereof which lies between the nip and the cap. This change of position of the spindle and bobbin. requires a special Serial No. 299,713. (NomodeL) Patented in England November '7, 1888, No. 16,115.
arrangement of the gearing for driving the spindle. This I have provided and it will be hereinafter described.
Such being the nature and object of my invention, I will now show by the accompanying drawings how the same maybe performed or put into practical operation.
Figure 1 of the annexed drawings illustrates such parts of a spinning or twisting frame as is necessary to show the application of my invention, and Fig. 2 is a fragmentary View illustrating the common method of arranging the spindle with reference to the de livery-rollers.
A is the framework of the machine, and B the bobbins containing the roving tobe spun and twisted. The said roving passesthrough guide-eyes 0, back rollers D, and front delivcry-rollers E, all arranged in the ordinary manner and usually worked in combination with vertical spindles F, as shown in Fig. 2, where it will be seen that a portion of the yarn, in passing from the delivery-rollers E, must of necessity rest upon the periphery of the front bottom roller, as will be observed and understood from said Fig. 2.
I prevent the yarn from resting upon the lower front roller by placing the spindle F with its axis at about right angles to a plane passing through the centers of the two front or delivery rollers and about tangent to both rollers at the nip, as shown in Fig. 1, by means of which the eyelet-board G (seen in Fig. 2) is dispensed with, and the yarn is free and at liberty to receive twist immediately after leaving the nip of the front rollers; consequently, as is obvious to those conversant with spinning and twisting, a more even twist can be put into the yarn and the spinning is thus much improved and finer counts can be spun from the same quality of fiber, while the yarn is not flattened by frictional contact with the bottom roller, but is left in .a round state.
necessarily somewhat different from that employed for driving vertical spindles, but the means shown in Fig. 1 are suflicient for the purpose.
It will be seen that II" is the main driving The apparatus for driving the spindle is drum or pulley, I and J being tension-pulleys, the former working upon a fixed stud and the latter carried by a bracket K, Working upon the stud L, the said bracket being weighted at M for the purpose of keeping the driving tape or belt N at a suitable tension. This construction enables the spindles on both sides of the frame to be driven conveniently from a common drum H, arranged between them and at a sufficient distance below the obliquely-arranged spindles to place the portions of the belt between it and the respective spindles at right angles to the latter, as they should be for driving. A single endless belt'is used to drive opposite spindles, and the drum H stands between the upper and lower sides of said belt, that portion of the latter which is above the drum being held down in contact with the latter by the tension-pulleys I J.
I do not herein claim, broadly, the particular arrangement of the spindle-axes with respect to the front or delivery rollers, as an arrangementvery similar to this has been before employed.
Having thus described my invention, I claim In a machine for the purpose specified, the combination, with the two sets of obliquelyarranged spindles on opposite sides of the frame, of the driving-drum H, arranged between and below the sets of spindles, the belt N, by which the spindles are driven from the said drum, and the tension-pulleys I and J at opposite sides of the drum, said pulleys acting on the upper strand of said belt, and pressing it down over the top of said drum, whereby both strands of the belt aremade to embrace the drum, the one above and the other below, as set forth.
In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.
HOIVARD PRIESTMAN.
