Description
Oct. 24, 1933. w B WALKER 1,932,027
DUST GUARD FOR SPINNING MACHINES Filed May 12, 1953 INVENTOR Wi/ham B. Walker and their supports.
Patented Oct. 24, 1933 UNITED STATES PATENT OFFICE 3 Claims.
In cotton spinning rooms, apparatus are employed for traversing one or more downwardly directed currents of air over the rows of spinning frames for the purpose of maintaining the frames and the work free from lint, fly, and other fine particles. Such apparatus is described and claimed in my Letters Patent 1,781,142, dated November 11, 1930. With the use of this apparatus in the caseof large package roving and long draft spinning, it has been found that particles of fiber are liable to be carried against the usual weight hooks of the spinning frames by the currents of air passing beneath the drawing rollers These fibers, by partially wrapping themselves about the post of the weight hook, tend to build up into a substantial size tier that is likely to be suddenly dislodged from the hook and its post by the continued currents of air and blown into the work. This frequently results in objectionable bunches being formed in the yarn.
The object of the present invention is to obviate the danger of such accumulation of fibers on the weight hooks. To this end, the invention consists in a dust guard that may be easily applied to the weight hook, and that effectively serves the purposes intended.
Referring to the drawing:
Figure 1 is a diagrammatical end view of a spinning frame having my improved dust guard applied thereto;
Fig. 2 is a detail sectional view of the dust guard shown applied to the weight hook of the spinning frame, the weight hook and portions of the associated parts being in elevation; and
Fig. 3 is an enlarged perspective view of the dust guards.
The spinning frame illustratedin the drawing isshown provided with a cop of roving 1, drawing rolls 2, rod 3, weight 4, weight lever 5 and weight hook 6, the parts being of the usual construction.
With the use of my said patented apparatus a part of the currents of air are directed, as indicated by. arrows in Figure 1, downwardly and forwardly beneath the drawing rollers and their associated parts and through the work. It has been found that these currents of air as they sweep over the weight hooks 6, are liable to deposit loose fibers thereon which tend to partially wrap themselves about the posts of the hooks until they are built up sufficiently in bodies or tiers as to cause the continued currents of air to suddenly dislodge them from the posts and blow them into the work, which of course is objectionable. In order to obviate the danger of this occurring, I provide a dust guard in theform of a cap 7 that may be easily applied over the weight hook. As shown, this cap 7, which may be made of sheet metal, is of substantially larger diameter than the post of the weight hook, has a flange 8 on its lower end which rests upon the bracket or shelf 9 that supports the weight hooks and has its cylindrical wall tapering upwardly and its upper end rounded over. The tapering cylindrical wall of the cap is provided with a longitudinally extending clearance slot 10 for the end of the weight lever.
To apply the dust guard or cap, the weight lever is unhooked from the weight hook, the cap passed over the weight hook, and then the end of the weight leverinserted through the slot and connected with the weight hook, the end of the weight lever serving to hold the cap in position.
With this dust cap applied, as the currents of air sweep downwardly in the vicinity of the weight hook and lever, any loose fibers carried thereby that strike the cylindrical surface of the cap slide easily over the curved and tapering surfaces thereof without danger of them accumulating or being retained on the cap. Thus it will be apparent that I have provided a simple, practical and convenient means which is capable of effectively overcoming I the disadvantages above described of the prior constructions.
As will be evident to those skilled in the art, my invention permits various modifications without departing from the spirit thereof or the scope of the appended claims.
What I claim is:
1. In a spinning frame having a weight hook and lever, the improvement which comprises a dust guard positioned over said weight hook having its rear side curved transversely in an arc of substantially greater diameter than the diameter of said hook, said guard having a clearance slot through which the weight lever extends.
2. A dust guard for a weight hook of a spinning frame comprising a cap-shaped member adapted to be positioned over the weight hook having a clearance slot therein for the end of the weight lever, the slot being arranged to permit the end of the lever to be inserted therethrough and connected with the Weight hook after applying the dust guard to the hook.
3. A dust guard'for a weight hook of a spinning frame comprising a cap-shaped member adapted to be positioned over the weight hook having a clearance slot therein for the end of the weight lever, said member having a tapering cylindrical upright wall, a rounded top, and a supporting flange on its lower open end.
WILLIAM B. WALKER.
