SPINNING RING AND TRAVELER.
SPECIFICATION forming part of Letters Patent No. 473,824, dated April 26, 1892.. Application filed May 2, 1891. Serial No. 391,389. (No model.)
To all whomit may concern.-
Be it known that 1, CHARLES H. CHAPMAN, a citizen of the United States, residing at Groton, in the county of Middlesex and State of Massachusetts, have invented a certain new and useful Improvement in Spinning Rings and Travelers, of which the following is a full, clear, and exact description.
This invention relates to that class of spinto ning apparatus known as ringspinning elevated eye for the yarn and is self-adj usting upon the race, all as I will proceed now more particularly to set forth and finally claim.
In the accompanying drawings, illustrating my invention, in the several figures of which like parts are similarly designated, Figure 1 is a plan view, and Fig. 2 is a vertical section, of the ring. Fig. 3 is a plan view of the base or holder. Fig. 4: is a plan view, and Fig. 5
0 is a side View, of the holder-neck. Fig. 6 is a sectional elevation, omitting, however, the ring-holder, illustrating the application of my invention in spinning. Fig. 7 is a side view, and Fig. 8 an edge view, of the traveler.
It has been found to be very desirable that the point of contact of the yarn with the traveler should be at the greatest distance from the center of motion of the traveler, and also that the traveler should have its portion which 0 engages the yarn capable of swinging toward and from the spindle as the centrifugal force of the traveler and tension of the yarn de mand. These desirable features are present in my invention. When ,the ring-race is so constructed as to compel the traveler to stand in an upright position, the traveler must be of such weight at its upper end that the tension of the yarn is not sufficient to overcome the centrifugal force, and hence there follows much spoiled work and much waste of time and material. my invention.
These objections I avoid in In practicing my invention it will be understood that, as in other ring spinning frames, my ring must be of the right size and the traveler of the proper weight to correspond with the number of the yarn and the desired speed. The holder or base a has the notches b for the reception of the screws commonly used to secure the rings to the ringrail, and these notches are made larger than the screw-shanks, in order to admit of the adjustment of the holders to secure as perfect concentrioity of the ring and spindle as may be. The holder is made with the upturned lips c on its inner edge. The neck d of the holder is made, in the preferred form as at concavo-convex ring, of sheet metal, slitted at d d 011 its upper and lower edges. By means of this lower slitted edge the neck is adapted to be sprung upon the lips c of the holder, and thereby to be securely united to such holder.
The ring-race e is made as a fiat beveled ring, having in its under face a groove 6', into which is sprung the upper slitted edge of the holder-neck d, whereby the race is united to the holder. The race is arranged upon the holder at about an angle of thirty degrees that is to say, with an upward and outward flare or slant.
The traveler f is constructed of suitable stiff spring metal, with a hook f at one end to engage the ring-race, an upwardly inclined shank f overlying the race and which terminates in an eye f atits highest end to receive the yarn, a curved portion f, working over the upper edge of the race, and a hook f engaging the lower face of the upper edge, the hooks f and f serving to connect the traveler and race. The traveler may be applied to the race by hooking one end over the edge of the race and springing the other end into place. When the traveler is adjusted upon the ring-race and in operation, its center of vertical motion is at the hook f and the traveler can swing outwardly until the shank f comes into contact with the ring-race, or it can swing inwardlyuntil the hook f comes into contact with the under face of the upper end of the race. In either case the traveler is held to the ring-race by'the hooks f and f instead of being held by one end only, as in other inventions of mine. As already intimated, the centrifugal force is so great upon a traveler constructed to clasp the ring-race when the ring is made to hold or compel the traveler to swing around in an upright position that it entirely defeats the object aimed at. If the traveler could be swung around upon the ring-race free from all restraint either by the ring-race or the yarn, so far as its outward or inward swinging motion is concerned, the traveler would seek at once a horizontal line in relation to its center of gravity and all of its centrifugal force would be sustained by the hook fthat is to say, its center of vertical motionand in this position there would be practically no resistance at the eye f through which the yarn passes; but when the traveler is held in a posit-ion where the shankf is in a perpendicular line the centrifugal force is very great. Between these two points, then, is the proper position to attain success, and in my construction of parts I have demonstrated the correctness of this proposition. The hook f clasps the inner edge of the ring-race, the hook or lip f prevents the disengagement of the traveler from the race, and the curve f,being described on a circle whose center is the center of vertical motion of the traveler, maintains the same relative position to the outer edge of the ringrace and allows the traveler to swing outwardly and inwardly, as maybe required, and prevents it from dropping down or being unhooked from the ring-race.
The shank f is thelever to the eye f. The eye f through which the thread passes, keeps the thread from slipping down upon the shank into the hook f, which it would do, were it not for the eye, as soon as the traveler should be thrown outwardly by the centrifugal force-an occurrence that would defeat the object sought to be attained by my invention.
In the art of spinning it is essential that the ring be concentric with the spindle, and this concentricity is no easy matter to preserve, inasmuch as so many forces tend to destroy it-for example, the liability of the spindle to careen out of aperpendicular line, the wear of the lifting-rods of the ring-rail, and the tension of the bands. WVhen there is eccentricity of the ring and spindle in the use of the ordinary ring and traveler, there is a yank upon the yarn at every revolution of the traveler, thereby causing a large number of breakages and a loss of production and material. With my invention this evil is reduced to a minimum, because the traveler will yield when the ring is out of center.
What I claim is 1. A spinning-ring composed of a holderbase having upturned lips, a ring-race constructed with a groove, and aneck constructed with slits in its lower edge to adapt it. to be sprung upon such lips, and thereby secure 1t and the base, and also constructed with slits in its upper edge, whereby it is adapted to be sprung into the groove of the ring-race to unite them, substantially as described.
2. A spinning-ring traveler having a hook at one end, a straight inclined shank terminating at its upper end in a yarn-eye, a curved spring portion whose center of motion is the aforementioned hook, and a stop-hook at the end of said curved portion, substantially as described.
3. An inclined ring-race flaring outwardly, in combination with a traveler having a hook to engage the inner and lower end of the race and vibrating thereupon as a lever upon its fulcrum and provided with an elevated yarnreceiving eye which has a to-and-fro motion relatively to the spindle, and also provided with a curved spring portion having a hook to engage the outer and under edge of the ringrace, substantially as described.
at. A travelerconstructed with an upwardlyinclined shank, a hook at the lower end of said shank to engage the inner edge of the ring-race, upon which the traveler swings inwardly and outwardly in relation to the spindle as a lever upon its fulcrum, a stop-hook to engage the outer edge of the ring-race, and a yarn-eye at the upper end of said shank, by which the yarn is prevented from slipping down upon the shank when the traveler is thrown outwardly by its centrifugal force, in combination with a ring-race upon which the said traveler can swing inwardly and outwardly in relation to the spindle to an angle of forty-five or more degrees toward the horizontal, substantially as described.
In testimony whereof I have hereunto set my hand this 27th day of April, A. D. 1891.
