MICHAEL E. SULLIVAN, OF NEW BEDFORD, MASSACHUSETTS, ASSIGNO R TO SAWYER SPINDLE COMPANY, OF MAINE.
SPINNING-'SPINDLE.
SPECIFICATION forming part of Letters Patent No. 728,042, dated May 12, 1903.
Application filed January 10,1903. Serial No- 138,4'77. (No model.)
This invention relates to spin ning-spindles;
and it has for its object the production of novel, simple, and eifective means for preventing slipping of the yarn-carrier or bobbin or upward displacement thereof due to centrifugal action.
In accordance with my invention the spindie is provided above the whirl with a flexibleand preferably elastic disk-like downhold, the periphery thereof frictionally engaging the interior of the bobbin when pushed down into operative position.- The application, of the bobbin acts to slightly depress the peripheral portion of the downhold, and any slipping or lifting movement of the bobbin relative to the spindle is prevented by the inherent resistance of the downhold. r.
The Various novel features ofmy invention will be described in the subjoined specification and particularly pointed out in the following claims.
Figure 1 is a side elevation and partial vertical section of a spinning-spindle'with one embodiment of my invention applied there to, the yarn-carrier or bobbin being shown in section in operative position. Fig. 2 is a side elevation of the whirl supporting sleeve, broken out at its upper end, with the downhold thereon with the bobbin omitted; and Fig. 3 is a transVerSesectiOnaI view on the line 3 3, Fig. I, looking down.
The rotatable spindlev A, its supportingcase A adapted to be attached to the spindle-rail in usual manner, and the whirl W, connected with the spindle by a downturned sleeve 10, are all of well-known construction to those skilled in the art.
As shown in Fig. 1, the yarn-carrier or bobbin B is hollowed out internally at its lower end at b to receive the upper end of the sleeve to when the bobbin is pushed down thereupon,
place. The downhold is a disk-like piece of downhold d is seated therein and held inflexible and preferably elastic material-such as rubber, leather, &;c.-having a central hole to enable it to he slipped over the upper end of the sleeve and into the groove w The external diameter of the downhold is slightly greater than the inside diameter of the hollowed portion 1) of the bobbin, and preferably the periphery is notched or non-continuous,
as at d Fig. 3, to increase the flexibility of the downhold at its periphery and also to .provide a plurality of engaging portions. 1When the bobbin is pushed down into place,
the periphery of the downhold engages the interior of the bobbin and is bent downward somewhat, as shown in Fig. 1, so that therev v I is a firm frictional engagement between the downhold and bobbin. The inherent resistance of the downhold prevents any slipping of the bobbin on the sleeve and also prevents the latter from being thrown upward by centrifugal action.
' Having fully described my invention, What I claim as new, and desire to secure by Letters Patient, is-
l. A spinning-spindle having an attached .whirl,and a flexible and elastic disk-like downhold rotatable with and extended laterally from the spindle above the whirl, tofrictionally engage the interior of a bobbin and preventslipping and upward movement thereof when the spindle is running.
2. A spinning-spindle having a downturned whirl-supporting sleeve secured thereto and provided with an annular groove near its upper end, and an annular,fiexible,elastic downhold held in the groove and having a noncontinuous periphery to engage the interior of a bobbin and retain it in position on the sleeve. I
A positive upward pull on" the bobbin readily disengages it when it is 'necessaryto dofi. p y The downhold obviates forcing the bobbin down hard upon the sleeve and prevents splitting of the hollow end of the bobbin.
