JOHN DODD, or OLDHAM, ENGLAND.
Letters Patent No.j114,274, dated May 2, 1871.
IMPRO VEMENT IN SELF-ACTING MUL ES FOR SPINNING.
The Schedule referred to in these Letters Patent and making part of the same.
same, reference being had to the accompanying draw,-
ing forming part of this specification.
My invention refers to that part of the self-acting mule or twiner known as the windingeon motion, and is designed to impart an increased velocity to the spindles when the yarn is being wound on a tapered portion thereof and the cop-nose is being formed.
, The arrangement most commonly in use for winding on is that of the quadrant or radial-arm winding-on chain, and it is to these parts that my invention has reference.
To accomplish the object of my said invention I employ the ordinary winding-on drum, but form upon one end thereof a scroll, gradually decreasing in diameter in proportion to therequired differential motion of the spindies, and I provide means for taking up any length of chain, so that it may be unwound from the said scroll when desired, or from a portion thereof.
In the accompanying drawing Figure v1 represents a partial view of a mule in cross-section with my improvements adapted;
Figure 2, a detached yiew of the winding-on drum; and
Figure 3, a detached view of the radial arm.
Similar lettersof reference indicate corresponding parts.
The frame-work of the mule is shown at a, the end A being the roller-beam end thereof.
Upon thisframe is mounted the usual quadrant b, to which motion is communicated from the shaft-c, and at d is the radial arm.
At f is the nut, which is traversed in the ordinary manner by the screw 2, and at g is what may be considered the usual point of attachment for the windingon chain h,- but according to my invention this part of the machine is constructed in a peculiar manner.
Within an extension, 11, of the nut is mounted a short shaft, j, upon which isa pulley, k, and upon the same axis are ratchet-wheels I, and also a lever-handle, m.
The part 'i carries" a clinch, a, which prevents the ratchet-wheel from turning in one direction, but leaves them free to do so in the other.
At ois the carriage, within which is mounted, as usual, the winding-on drum 1), and which communicates motion to the tin drum (1 in the ordinary manner.
The winding-0n drum 1) is construoted'as a cylinder from r to s, and so far it is as usual; but according to my invention'one end thereof is provided with a scroll, it, tapering toward one end.
The winding-on chain is attached'to the smaller end of the scroll t. It is then coiled around the said scroll, and subsequently around the parallel part of the drum.
From thence it passes over a roller, g, then extends upward, and is made fast to the pulley'lc.
The operation is as follows:
According to the position of the parts shown, the winding on, in order to form a cop, is just commencing, the nut f being at the bottom of the radial arm. as usual.
The machine being now put in motion, the spinning and winding on will go on in the ordinary manner, the
nut f being traversed by the screw, 0 until it arrives at the position shown by the dotted lines, by which time the base or full diameter of the cop will have been at tained, and theoperation will then go on, as is well understood, until the nose of the'cop is being formed, at which time my invention is particularly designed to come into operation, although it may be varied in this particular, as will hereinafter be mentioned. I During the operations above alluded to the chain It has been unwound from the parallel part only of the drum 1), a suficient length of the said chain being wound thereon to prevent the motion of the carriage from causing it to proceed from the scroll t, but that part of the apparatus now comes into operation.
Suppose the spindles to continue to revolve at the same speed as they have hitherto done, their gradu= ally-decreasing diameter would not afford a proportionate winding-on or taking-up power, a deficiency which, as is well known, leads to a looseuess in the formation of the nose of the cop,and to remedy which my invention is desigiied, and operatesiu the followiug manner:
The attendant, by means of the hand-lever m, turns the pulley k a port-ion of a revolution, by which. means a certain length of chain is drawn off the drum 1) and is wound upon the pulley k, and the length of the said chain between the point g and the drum 1) is necessarily shortened. When, therefore, the carriage runs in there will not be suifioient length of chain to remain upon the parallel part of the drum, and it will of necop, that being the point of greatest importance, but- Having thus described my I have above particularly-alluded 'tolmy invent-ion as coming into operation for forming the nose of the it will be evident that, if desired,.tl1e' scroll may be bronght into operation at an earlier stage of the formation of thelooip,in order" in like manner to compensate for the taper oft-he spindle at lower positions.
I arnaware that scrolls have heretofore been formed 1 npon'ivimi ing-on drnms,'and therefore lay no claim thereto; but
invention,
-, I claim as new and desire to secure by Letters
