Description
Patented Dec. 30, 1947 RING FOR SPINNING AND TWISTING YARN Henry B. Stuart, Whitinsville, Mass, assignor to Whitin Machine Works, Whitinsville, Mass. a corporation of Massachusetts Application August 14, 1945, Serial No. 610,730
1 Claim. 1
This invention relates to a spinning or twisting ring of the type having a vertically extended body portion constituting, a traveller flange, said rings being commercially known as vertical flange rings.
It is the general object of my present invention to improve the ring shown in my prior Patent No. 1,998,973, issued April 23, 1935.
More specifically, it is the object of my invention to provide a ring so designed and constructed that substantially uniform traveller pressure is constantly maintained, even when winding filling bobbins.
To the attainment of this object, I have provided a ring in which the inner traveller-bearing surface is convexly curved inward and in which the upper inner edge is substantially and convexly relieved and cut away to provide yarn clearance. I also provide a ring which does not require an offset and unbalanced traveller.
My invention further relates to arrangements and combinations of parts which will be hereinafter described and more particularly pointed out in the appended claim.
A preferred form of the invention is shown in the drawings, in which Fig. 1 is a sectional front elevation of my improved ring and associated ring rail, shown in operative relation to a filling type bobbin;
Fig. 2 is an enlarged cross section of the improved ring and means for lubricating the same; and
Fig. 3 is a plan view of the ring, with the bobbin and yarn load shown in section.
Referring to the drawings, I have shown a ring R having a vertically extended body portion or vertical flange mounted in a ring rail l and associated with a bobbin B rotated by a spindle l2. Yarn Y is drawn downward through a guide eye l4 and is directed to the bobbin B by a traveller T. A lubricating wick I5 may be provided as shown in Fig. 2 and as described in detail in my prior patent above cited.
.It is assumed in Fig. 1. that the bobbin B and spindle I2 are vertically fixed and that the ring rail l0 and ring R are vertically reciprocated but the reverse construction may be used to equal advantage.
My improvements relate largely to the specific ring section as best shown in Fig. 2. The inner traveller-bearing surface 20 of the ring is made slightly convex and is slanted outwardly in its lower portion. The upper inner corner 22 is substantially cut away and rounded in a continuous curve extending substantially 90 to the outer 2 surface 23' and with its center very slightly displaced inward from said surface. The two curved surfaces meet in a line about one-fourth of the height downward from the upper edge.
The lower edge of the ring is rounded at 24, and the lower outer surface 25 is of less diameter than the upper outer surface 23.
The traveller T is substantially of standard vertical-flange type, with a shank 30, which is substantially straight throughout its height, a semi-circular lower end 3|, a curved and outwardly extended upper end portion 32, and a depending end portion'33. The radius of the lower end 3| is slightly greater than the radius of the lower ring surface 25.
The variation in yarn pull on the traveller T between the small top diameter of a cone wind and the large bottom diameter is indicated in Fig. 3. As the direction of pull changes, the traveller rocks against the convex inner travellerbearing surface of the ring and the lower end 3| swings in and out'across the rounded lower edge 24 of the ring. This mutual and automatic adjustment tends to keep the traveller pull uniform.
It has been found by mill tests that my improved ring may be used with higher spindle speeds and with reduced traveller breakage. The increased clearance at the top of the ring reduces yarn breakage, particularly at starting. The thread-engaging point on the traveller, when in rotation, is always at a greater radius than the traveller-engaged point on the inner bearing surface of the ring. The traveller is thus much better balanced when running than was the offset traveller on the ring shown in my prior patent.
While the changes in construction over said prior patent are somewhat detailed, it has been shown under test that these 'changes are important.
Having thus described my invention and the advantages thereof, I do not wish to be limited to the details herein disclosed, otherwise than as set forth in the claim, but what I claim is:
In the combination of a ring having a vertically extended body portion constituting a traveller REFERENCES CITED The following references are of record in the file of this patent:
