RING FOR SPINNING MACHINES. I No. 501,243. 4 Patented July 11, 1893.
SPECIFICATION forming part of Letters Patent No. 501,243, dated July 11,1893.
Application filed March 2'7, 1893. Serial 110.467 ,859. (N0 model.)
To aZZ whom it 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 Rings for Spinning-Machines, of which the following is a full, clear, and exact description.
This invention relates to that class of spinning apparatusknown as ring-spinningframes or machines.
One object of the invention is to equalize the tension on the yarn; and another object is to simplify'the construction, and increase the durability of the ring. In effecting these objects of my invention, I make use ofaring having a tapering or wedge-shaped race constructed in such manner as to allow the traveler to wedge itself upon the race automatically as the tension of the yarn or the centrifugal force predominates, substantially as 1 will proceed now to describe and finally claim.
In the accompanying drawings illustrating my invention, in the several figures of which like parts are similarly designated, Figure l is a plan view, and Fig. 2 is a vertical section of the ring. Fig. 3 is a plan view of the under side of the ring. Fig. 4 is a plan view of the ring and traveler spinning upon a bobbin filled with yarn. Fig. 5 isa plan view of the ring and traveler spinning upon an empty bobbin. fied form of ring, and Fig. 7 is a vertical section of the double ring-race nowin general use.
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.
In constructing my ring a, I provide forits fastening to the ring-rail by means of the notched projections I), through which screws, such as are commonly used, pass to secure the ringto the ring-rail, andthese notches are made larger than the screw-shanks in order to admit of adjustment to as perfect concentricity of the ring and spindle as may be.
Should it be found in practice that clearance for dust or lint is necessary, a portion of the lower edge of the ring which comes in contact with the ring-rail, may be cut away as Fig. 6 is a side elevation of a modi-' shown at c in Fig. 6, the projections 12 only coming in con tact with the ring-rail and thereby leaving an opening between the ring and the ring-rail.
The ring is constructed with the internal flange 01, which is surrounded by the ringrace ef Fig. 2. This race is constructed of wedge-shape,increasing in thickness as it increases in diameter, its upper side being substantially horizontal, as shown in Fig. 2. The traveler g is sprung over the flange d, which prevents the traveler from being disengaged from the ring. The thread t passes through the traveler g to the bobbin or yarn upon which it is being wound and the traveler by centrifugal forceis thrown outwardly from .its
center of revolution, which is practically the a center of the spindle s untilthe feet g, g, of the traveler come in contact with the wedgeshaped race ef. The bow of the traveler is not intended to touch the flange 01 when the traveler is in operation. Should the thread break it is readily engaged with the traveler by pressing the thread against the traveler which will force the traveler against the flange 01 causing the traveler to rise and the thread t will slip under the foot of the traveler into place as shown in Fig. 2.
With a ring and traveler of the common form as shown in Fig. 7, only one foot of the travelerA comes in contact with the ring-race B, when the traveler is in operation, unless too great a tension is created by the traveler being too heavy or by some imperfection in the ring, either of which will sometimes cause .the traveler-bow to run against the flange which will soon cut the traveler in two. In this form of spinning ring, the wearing surface of the traveler upon the ring-race B, is a mere line of the width of the foot of such traveler, whereas in my ring it is at least equal a great advantage in its durability over any now in use. Then the traveler is first put on, it will clasp the ring-race at the inside edge of the wearing surface shown in Fig. 5, and as the traveler runs, its feet will wear and the centrifugal force will throw the traveler outwardly from its center of revolution and the traveler will gradually seek a new point of contact upon the ring-race thereby utilizing abearing surface equal to that shown in Fig. 5. When the yarn is being spun and wound upon the empty bobbin, the pull of the yarn is in aline as shown in Fig. 5, and when in this position the pull of the yarn is sufficient to overcome a portion of the centrifugal force and the traveler is not forced upon the wedge-shaped ring-race so tightly. As the bobbin fills with yarn, the pull of the thread gradually changes to a point more in line with the course of the traveler in its revolution, and when the bobbin is filled with yarn, as shown in Fig. 4, the pull of the yarn t, is nearly in line with the course of the traveler and at this angle there is practically no resistance in opposition to the centrifugal force 011 the traveler. The.traveler, therefore, at this point, is thrown out upon the wedgeshaped ring-race with sufficient force to cause the traveler to wedge upon the ring-race more tightly thereby increasing the tension of the thread and off-setting in a great measure the variation of tension which exists with the ordinary ring and traveler.
By reference to Fig. 2, it will be noticed that the ring-race and flange cl are elevated sufficiently to prevent the travelerfrom coming in contact with the ring-rail.
What I claim is- 1. A spinning ring having a wedge-shaped race and a flange to restrain the inward movement of the traveler, substantially as described.
2. A spinning ring having a wedge-shaped race, and a flange at its inner edge arranged in a plane substantially at right angles thereto, substantially as described.
3. A spinning ring having a flange and a wedge-shaped race and provided with means for securing the same to the ring-rail, substantially as described.
4. A spinning ring having a wedge-shaped race provided with an internal flange, in combination with a traveler which will tighten or loosen upon said race automatically as the centrifugal force or the tension of the thread may predominate, substantially as described.
5. A spinning ring having an elevated vertical flange surrounded by a wedge-shaped race, combined with means for adjustably attaching the ring to the ring-rail, substantially as described.
6. A spinning ring havinga flange, a wedgeshaped race, means to secure the same to the ring rail, and an opening between the lower edge of the ring and the adjacent surface of the ring rail when applied thereto, for clearance of lint, dust, &c., substantially as described.
In testimony whereof I have hereunto set my hand this 24th day of March, A. D. 1893.
