Patented Nov. 17, 1936 UNITED STATES SPINNING RING AND SECURING DEVICE THEREFOR George West, Whitinsville, Mass., assignor to Whitin Machine Works, Whitinsville, Mass., at corporation of Massachusetts Application January 29, 1936, Serial No. 61,343
3 Claims.
This invention relates to spinning or twisting frames and particularly to means for securing a spinning or twisting ring in a ring rail.
The invention is particularly designed for use in connection with ring rails produced from sheet metal by pressing or other forming operations.
It has not been found practical to secure a ring in such a sheet steel ring rail by using the attaching means heretofore commonly used with cast iron ring rails, on account of the comparative thinness of the sheet steel rail.
It is the general object of my invention to provide an improved device for securing a spinning or twisting ring or a ring holder in a ring rail formed of sheet metal of relatively small thickness.
My invention further relates to arrangements and combinations of parts which will be hereinafter described and more particularly pointed out in the appended claims.
A preferred form of the invention is shown in the drawing, in which Fig. 1 is a plan view of a portion of a ring rail with a twister ring mounted therein;
Fig. 2 is a transverse sectional elevation, taken along the line 2-4 in Fig. 1;
Fig. 3 is an enlarged sectional elevation, taken along the line 33 in Fig. 2;
Fig. 4 is a plan view of a portion of a ring rail having a spinning ring and ring holder mounted therein;
Fig. 5 is a transverse sectional elevation, taken along the line 5--5 in Fig. 4;
Fig. 6 is an enlarged sectional elevation, taken ,along the line 6-6 in Fig. 5, and
Fig. 7 is a perspective view of the locking ring.
Referring to Figs. 1 to 3, I have shown a portion of a ring rail l having a circular opening ii to receive a ring I2. In Figs. 1 to 3 the ring 12 is shown as a vertical twister ring having a cylindrical outer surface l4 adapted to fit snugly in the opening il in the ring rail ID. The ring l2 also has an external annular flange l adapted to rest on the upper surface of the rail l0 and thus position the ring l2 vertically.
The cylindrical outer surface ll of the ring I2 is provided with an annular concave groove 20, the major portion of which is below the bottom of the ring rail II) when the ring 12 is in the position shown in Fig. 3. v
A locking ring 22 is formed of spring steel wire or othersimilar material and preferably has the shape indicated in perspective in Fig. 7 and is of such diameter that when snapped over the lower portion of the ring below the ring rail it will firmly seat itself in the groove 20.
An end portion 23 of the locking ring 22 is outwardly and downwardly offset to provide for convenient removal of the locking ring when desired.
In order that the ring I! may be held firmly seated in the ring rail l0, it is desirable that the locking ring 22 should be wedged between the lower surface of the ring rail I0 and the lower edge of the groove 20, as clearly shown in Fig. 3. It is also desirable that the locking ring should not bottom" in the groove 20, as in that case the wedging action of the locking ring may be lost.
Consequently, the groove 20 should be so located with respect to the thickness of the rail and the cross-section of the locking ring that the distance between the lower edge of the groove and the under face of the rail will be slightly less than the cross section diameter of the locking ring.
The construction above described has been found by actual test to very firmly retain a ring in a ring holder and the locking ring may also be quickly and easily removed to release the spinning or twister ring when desired.
Particular attention is called to the very simple additional operation on the ring l2 which is necessary to adapt the same to the purposes of my invention. It is merely necessary to provide the cylindrical outer surface H of the ring I! with the annular groove 20. No extra or additional operation whatever .is necessary on the ring rail II], the ring I2 being seated directly in the usual circular opening cut straight through the ring rail to receive the ring.
In Figs. 4, 5, and 6 I have shown the adaptation of my invention to a construction in which a spinning ring 30 is mounted in a ring holder 3| having a cylindrical outer surface 32 adapted to fit in a circular opening 33 in a sheet metal ring rail 34. An annular groove 35 is provided in the cylindrical surface 32 and is so positioned that the locking ring 36 will maintain the parts in the position shown in Fig. 6, with the ring wedged between the under surface of the ring rail 34 and the lower edge of the groove 35, all as previously described.
The second form of my invention possesses all of the advantages of simplicity and reliability which are found in the form shown in Figs. 1 to 3.
Where the term spinning ring occurs in the claims, it is to be understood as including rings used in both spinning and twisting operations.
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 claims, but what I claim is:
1. In a spinning frame, a sheet metal ring rail having a series of circular openings having straight side walls, a spinning ring for each opening having a cylindrical outer surface associated therewith and having an external supporting shoulder above said cylindrical surface, and a locking ring for each spinning ring comprising a resilient open wire circle, the cylindrical outer surface associated with said spinning ring having an annular groove for said locking ring, and the lower edge of said groove being at a slightly less distance from the bottom of said ring rail than the diameter of the wire forming said locking ring, whereby said spinning ring is tightly held from upward movement in said ring rail but said locking ring is not seated in said groove.
2. In a spinning frame, a sheet metal ring rail having a series of circular openings having straight side walls, a spinning ring for each opening having a cylindrical outer surfaceand having an external supporting shoulder above said cylindrical surface, and a locking ring for each spinning ring comprising a resilient open wire circle, the cylindrical outer surface of said spinning ring having an annular groove for said locking ring, and the lower edge of said groove being at a slightly less distance from the bottom of said ring rail than the diameter of the wire forming said locking ring, whereby said spinning ring is tightly held from upward movement in said ring rail but said locking ring is not seated in said groove.
3. In a spinning frame, a sheet metal ring rail having a series of circular openings having straight side walls, aring and ring holder for each opening, each ring holder having a cylindrical outer surface and having an external supporting shoulder above said cylindrical surface, and a locking ring for each holder comprising a resilient open wire circle, the cylindrical outer surface of said holder having an annular groove for said locking ring, and said locking ring being slightly greater in diameter than -the distance from the bottom of said ring rail to the lower edge of said groove, 'said locking ring being wedged between the lower edge of said groove and the under side of said ring rail but not seating in said groove.
