Specification of Letters Patent.
Patented Nov. 21, 1905.
Application filed April 3, 1995. Serial No. 253,487.
d raftsman, a subject of the King of Great Britain, residing at 26 Manneville road, Keighley, in the county of York, England, have invented certain new and useful Improvements in Spinning-lVIaohines, of which the following is a specification.
The subject of my present invention relates to certain improvements for which Letters Patent were granted to one Smith Ambler, dated August 6, 1895, No. 544,203, and has for its object to provide a means for transferring the spindle-driving band from the dead to the live pulley in apparatus employed in spinning, twisting, doubling, and winding yarns and threads which shall be less violent in its action than the one described in said former patent.
In the twisting and doubling of yarns and threads on the flier system, in which the flier leads the bobbin and where the latter is pulled round by the former by means of the threads connecting them, it has been found in practice that where the bobbin is abnormally large for the counts or strength of yarn that is to be twisted upon it the sudden starting of the spindle, acting on the bobbin by means of the threads in its endeavor to overcome the inertia of thesame, has resulted in the threads themselves being broken in consequence of the sudden pull or shock to which they have been subjected, and this eifect has had the result of somewhat restricting the scope of useful- In the application of the said former invention to cap or ring twisting and doubling it has been signally successful, and the advantage of a spindle responding quickly to the touch of the operator and acting in unison with the yarn-delivery rollers has been greatly appreciated by those engaged in the trade, and the limiting effects referred to above have no application in re-' spect of these systems.
In the carrying out of the former invention the live-pulley had formed on the outer edges of its periphery two or more snails or cams, and when effecting the transfer of the drivingband from the dead to the live pulley by means of mechanism described in the former specification one or other of these snails or cams caught the band and forced it into its normal position on the live-pulley; but in so doing its action on the spindle and bobbin was apt to be sudden and jerky, whereby the result was the evil above described.
I have termed my invention a spinningmachine. This title is adopted simply for convenience, for it will be obvious as the nature of the invention is better understood that the machineis adapted for spinning, winding,
twisting, and doubling yarns, threads, and
other materials.
By the aid of my present invention I have sought to overcome this difficulty, and the means by which I perform this will be understood by reference to the accompanying drawings, in which Figure 1 shows a plan view of a series of four live-pulleys, one of which, A, (only one of a pair of usual driving-bands,)is shown in position for driving the spindles and with the cams in their horizontal position, while in the case of the pulleyB its corresponding drivingband is shown in the driving position with the cams in their vertical position. In the case of pulley C the two bands are shown in the position they assume when thrown off the driving-surface by the cams onto the side surfaces, and in the case of the pulley D the bands have both been omitted. Fig. 2 shows one of the pulleys,as A,with the two driving-bands on the larger and driving surface in elevation. Fig. 3 shows, to a larger scale, parts of two of the pulleys in sectional elevation with one of the intermediate dead-pulleys or rest-surfaces. Figs. 4 and 5 show the cams separately by edge and side views to a like scale.
It will be seen that my improved live-pulley at is made of sufficient width to drive two spindles, one on each side of the machine, and that the profile of its periphery is formed so as to produce two diameters1 its larger and driving diameter, and 2 its smaller diameter. Snails or cams 3 are placed at suitable positions to connect the smaller with the larger diameters.
The diameter of the dead-pulley b is substantially identical with that of the less diametrical portion of the live-pulley. Asection of the spindle-driving band is shown in three positionsat 4 on the dead-pulley when the spindle is at rest, at 5 in the act of passing from the dead to the live pulley, at 6 in its driving position on the live-pulley.
The action of the driving-band will at once be apparent. When in the position indicated at 4, the spindle is absolutely at rest, the driving-band is hanging very loosely on the deadpulley or rest ring or surface I) in consequence of its having fallen from a high to a lower level.
When the operator sets the transferring mechanism into motion, the band in a moment assumes the position shown at 5. This gives a trailing action to the band, which of course has its influence upon the spindle, im parting life and motion to it, and the spindle to the bobbin by the threads connecting them. Thus my object is achievedviz., inertia on the part of the bobbin is overcome, not violently or with a sudden jerk, which tends to break the threads, but by means at once gentle and without the slightest shock or undue tension upon the threads.
6 indicates the driving-band in its running position, having been lifted from the low to the high level by means of the snails or cams 3 above referred to.
In Fig. 2 s s indicate in section the positions of bars or supports, secured lengthwise of the machine, to support the dead-pulleys or rest-surfaces.
The driving-bands 71; may be moved into the path of the snails, cams, or projections 3 3 on the driving-pulley a by means of fingers or guides, such as are indicated at q, and be carried by a cranked arm 9 in the said former specification.
It is of course to be understood that although I have described the passing of the driving-band from the dead to the live pulley as passing through three distinct operations or stages the transferring from the one to the other is accomplished in a moment of time in response to the touch of the operator and at the same time in unison with the delivery of yarn from the delivery-rollers.
Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, I declare that what I claim is 1. In an apparatus of the class described, a pulley having its rim of two diameters, the portion of greater diameter constituting a live or active face and the other portion a dead face, said pulley having means for transferring a band from the portion of smaller diameter to the portion of greater diameter.
2. In an apparatus of the class described, a pulley, the rim of which is of two diameters, the portion of greater diameter constituting a live or active face and the other a dead face, said pulley having means for transferring a band from the portion of smaller diameter to the portion of greater diameter in combination with a rest-ring or dead-pulley.
8. In an apparatus of the class described, a pulley having a rim of two diameters, the portion of greater diameter serving as the operative part and the portion of, smaller diameter as a dead or inoperative part, said pulley being provided with cams to effect the transfer of a band from the smaller diameter to the portion of greater diameter in combination with a dead-pulley separate from the other pulley and placed at the side of the latter, the diameter of the dead-pulley being substantially the same as that of the portion of smaller diameter of the first-mentioned pulley.
In testimony whereof I have hereunto set my hand in presence of two subscribing Witnesses.
