UNITED STATES WILLIAM J. HUBBARD, OF YARMOUTH, NOVA SCOTIA, CANADA.
MECHANICAL CUSHION ROLL FOR SPINNING- FRAMES.
Application filed June 11, 1925. Serial No. 36,497.
To all whom it may concern:
Be it known that I, VILLIAM J. I'IUBBARD,
a citizen of Canada, residing at Yarmouth,
Nova Scotia, Canada, have invented certain new and useful Improvements in a Mechanical Cushion Roll for Spinning Frames,
ofwhich the following is a specification.
The present invention relates to the important principle of roll drafting in the 1D textile industry. This principle of roll drafting is the most important feature of parallelizing and attenuating machinery. I
contemplate an improvement in one of the drawing rolls, and particularly the top rolls. The type of top delivery roll for spinning textile industries now in most common use has a body provided with a bore for receiving the shaft, and on the body is a. felt undercovering about which is placed a leather top covering. The felt covering is relied upon a cause a give, that is a cushion for the top leather covering. Any defect in the top covering of the top roll will cause the end, that is yarn feeding to the bobbins, to break. It is well established that a large majority of this breaking is caused by the top drawing roll. Furthermore, the cost of the felt is very expensive, and with the common type of top roll, the grade of the leather must be the very best, and is there fore also very expensive, so that the replacing of the leather which must be done very frequently proves a great expense in the textile industry and this is increased because the felt undercovering must always almost invariably be renewed with the top leather covering.
The principal object of my invention is to provide a top drawing roll which is mechanically cushioned, thereby allowing the use of a cheap grade of top leather covering, and doing away entirely with the expense of the felt.
Another very important object of my invention is to provide a mechanically cushioned roll of this nature which will be far more efficient and reliable in operation than the common type of roll now in use.
A still further ver 1 important object of the invention is to provide a roll of this nature which is exceedingly simple in its construction, inexpensive to manufacture, strong, durable, not likely to easily become out of order, and otherwise well adapted to the purpose for which it is designed.
extending bore including the two frusto conical shaped portions 2 having their smaller ends in communication with each other. Recesses 3 are formed at the ends of the bore and caps 4 are mounted therein being held in place by suitable fastening elements 5. These caps are provided with openings 6 which are coaxially aligned with the bore of the body 1. Frusto-conical shaped bearings 7 are disposed one in each portion 2 of the bore of the body 1. Springs 8 of any suitable type, here shown as coil springs, are positioned in the recesses 3. In
the present illustration these coil springs bear against the outer ends of the bearings 7 and against washers 9 abutting the inner surface of the caps 4:, and tend to urge the bearings 7 inwardly toward each other. The usual shaft 10 passes through the openings'6 of the caps 4: and through bores 11 of the bearings 7. The bearings 7 are free to slide toward or away from each other on the shaft 10.
As the description has thus far progressed, it will be seen that any pressure on the body 1 directed inwardly toward the axis thereof would tend to separate the bearings 7, thereby forming a cushion mounting for the body 1 owing to the resiliency of the springs 8. This mechanical cushioning feature takes the place of the expensive and not very reliable felt undercovering of the rolls now in common use.
As heretofore stated, the covering used for the body 1 is of a relatively cheap grade as compared with the coverings now in use.
The under covering 18 may be of canvas while the top or outer covering 14 may be of a relatively cheap grade of leather.
It is thought that the construction, operation, and advantages of this invention will the now be clearlyunderstood Without a more detailed description. It is desired, however,
to point out that with this mechanical cusl1-' ioning feature there is less likelihood that grooves will be worn into the leather covering l l and therefore a cheaper grade may be used to better advantage than the more expensive grade now in use. This cheapens the construction considerably and saves considerable, particularlyfin the labor incident to recovering of the rolls, and also in the time lost in taking the rolls out of the spinning frame.
The present embodiment of the invention has been disclosed merely by way of example and attains all the features of advantage enumerated as desirable in the statement of the invention and the above description. It is apparent that numerous changes in the details of construction, in the sizes, in the materials, and in the combination and arrangement of parts may be restored to without departing from the spirit or scop'eof the invention as hereinafter claimed or sacrificing'any of its advaz'itages; c
Having thus described the invention, What I claim as new and desire to secure by Letters Patent is l. A drawing roll of the class described including a body, a covering on the body, a pair of cone journals in the body, and resilient means for urging the cone bearings toward the center of the body, said bearings dapted to be slidably received on a shaft. 2. A mechanically cushioned roll for textile spinning frames including a body having a pair of frusto-conical bores extending longitudinally thereof and having their smaller ends communicating at the center of the body, cone shaped bearings extended. into the bores and provided with aligning bores for receiving a shaft, caps at the ends of the body, and resilient means in the caps urging the bearings toward each other.
In testimony whereof I aflix my signature.
