' 7 Claims. (01. 118-59) This invention relates to certain new and useful improvements in the spinning art and particularly to the spinning rings and the bar travelers employed in connection with spinning machines.
One of the objects of the invention is to so design the spinning ring and the bar traveler as to provide a two-point bearing contact for the traveler; on the ring when the traveler is operating at low speeds, as when starting and stopping the spinning machine, and thereby so support the traveler that chattering and raking is eliminated;
Another object is the provision of a spinning right having a two-point bearing contact for the traveler when operating at low speeds, and wherein one of said bearing contacts is solely used when the traveler is operating at high speeds.
Other features of the invention reside in the construction and arrangement of parts herein.- after described and particularly pointed out in the appended claims.
In the accompanying drawing:-
Figure l is a top plan View, partly in section, of a spinning ring embodying my invention and showing the bar traveler positioned thereon. Figure 2 is an enlarged cross section thereof taken in the plane of line 2-2, Figure 1. Figures 3 and 4 are enlarged fragmentary cross sections of the spinning ring and associated parts showing the relative positions of the traveler on the ring when operating at low and high speeds, respectively. Figure 5 is a perspective view of the bar traveler.
12 in the bar, as seen by dotted lines in Figure 2.
Mounted on the reciprocating bar 11 and surrounding the take-up spool is the usual supporting base or holder 13 for the spinning or traverse ring upon which the bar traveler, indicated generally by the numeral 14, is adapted to revolve. During the normal operation of the spinning machine, the bar traveler assumes a more or less outwardly-directed position, asshown in Figure 4, and revolves with and about the takeup spool, the thread passing under the traveler before being wound upon the spool and the bar 11 being reciprocated so that the threads are uniformly wound in layers upon the spool. When starting and stopping the spinning machine, the traveler revolves at a comparatively low speed and assumes the substantially upright position shown in Figure 3.
The holder 13 which supports the improved spinning ring, may be stamped or otherwise formed from sheet metal, the same being in the form of a flat ring-like base having a neck 15 rising from its inner periphery, and having yieldable clamping posts or brackets 16 rising from its outer periphery for detachably receiving and holding the spinning ring in place on the traverse bar 11. As is customary, this holder is provided at its outer edge with slotted ears 1? for securely fastening the same to the bar 11.
In its preferred form, the spinning ring for guiding the bar traveler about the take-up spool consists of an annular body 18 made of a fiber composition or like material. This ring-body is shaped, in cross section, in the manner shown in Figures 2, 3 and 4, and includes a substantially semi-circular, inner peripheral bearing face 19 for the bar traveler merging into outwardly and upwardly inclined top and bottom surfaces. Depending from its outer edge, the ring body has a rim or flange 20 and appiied to such edge is a retaining or holding means for the fiber body preferably consisting of inner and outer rings or coilars 21, respectively, which form a unitary structure with the fiber ring to not only protect itbut to also enable it to be fitted to the holderbase 13.
The traveler designed for use withthis spinning ring preferably consists of a cross bar 23 which is uniformly curved from end to end about a vertical axis and which has depending legs 24 at its ends terminating in outwardly-facing bearing arms 25, the latter having their terminal ends convexly curved or bent, as indicated at 26, for a purpose which will hereafter appear. As seen in Figure 1, the bearing arms 25 extend substantially in line with or in the direction of curvature of the cross bar 23.
Under the normal or high speed movement of the car traveler about the ring 18, the same has a single or unitary bearing contact with the ring, and as shown in Figured, this contactis with the semi-circular bearing face 19, the traveler'being curved at the junction of its legs and arms to substantially the curvature of such face or slightly larger so that it has a true and unitary bearing on the inner periphery of the ring and is further permitted a freedom of rocking or rolling movement thereover. Under these conditions, the bearing arms 25 are free and clear of the adjoining portions of the ring. When starting and stopping the spinning machine, the traveler necessarily moves at a low speed and to prevent its wobbling and chattering I provide the ring with a second bearing face 27 in substantially close proximity to the inner peripheral bearing face in concentric relation therewith but facing generally in a direction opposite thereto, thereby providing a twopoint bearing for the traveler under these conditions. This second bearing face 2'7 is adapted to be engaged by the convexly curved ends 26 of the bearing arms 25 during the starting and stopping movements of the traveler, as shown in Figure 3, and to provide clearance for the terminal ends of the bearing arms in this two-point hearing position of the traveler, the bottom side of the ring 18 preferably has an annular groove 28 therein into which said terminal ends may extend and yet be free from contact with the ring except at the bearing face 27. It will be noted that the second bearing face 27 is formed by that edge of the groove 28 nearest the peripheral bearing face 19. The curved portions of the traveler-arms 25 between their terminal ends 26 and depending legs 24 clear the bottom face of the ring 18 in the slow speed position of the traveler shown in Figure 3.
I claim as my invention:
1. A spinning ring, comprising a body having a substantially semi-circular inner peripheral bearing face merging into an outwardly and upwardly inclined bottom surface terminating in a second bearing face for a bar traveler, said second bearing face being disposed above the plane of said bottom surface and concentric with said peripheral bearing face constituting a unitary bearing face, the latter for the traveler when running at high speeds and said peripheral and second bearing face jointly constituting a two-point bearing for the traveler when running at starting or slow speeds.
2. A spinning ring, comprising a body having an inner peripheral bearing face with which a bar traveler is adapted to engage at both high and low speeds, the bottom side of said ring-body having an annular groove therein forming at that edge thereof, nearest the peripheral bearing face, a second bearing face with which the adjoining end portions of the bar traveler are adapted to engage at low speeds, the traveler clearing said second bearing face at high speeds.
3. A spinning ring, comprising a body having an inner peripheral bearing face for a bar traveler and a depending rim at its outer periphery, the bottom side of said ring-body having an annular groove therein adjoining its rim and forming at its inner edge, alongside the adjacent bottom side of the ring-body, a second bearing face for the traveler.
