SPECIFICATION forming part of Letters Patent No. l767,011, dated August 9, 1904.

Application filed June Z1, 1901i. Serial No. 213,482. (No model.)

.To fir/ZZ whom, 7?/7 771x777/ cow/007171,.'

Be it known Ythat I, JOHN E. Pnns'r, a citizen of the United States, residing in Worcester, in the county of lVorcester and VState of Massachusetts, have invented a new and useful 1Inprovement in Spinning Spindlesand Bobbins, of which the following is a specification.

This invention relates to rotatable spinning spindles and bobbins, and particularly to that class of spinning" apparatus in which the bobbin is connected with and rotated by the spindle by the operation of centrifugal action upon a clutching or engaging mechanism intermediate of the bobbin and the spindle.

In this inventionthe clutches or engaging devices are pivotally sustained in substantiallyvertical positions between the spindle and the bobbin, vand when motion is imparted to the spindle they are rotated horizontally on their axes -by the centrifugal action produced by the rotation of the spindle or by said centrifugal action aided by atmospheric resistance until the outer edges of said clutches are thereby brought into engagement with teeth, preferably ratchet-shaped, on the inner face of a ferrule which lines the inner walls ofthe chamber in the head of the bobbin,

- whereby the spindle and bobbin are connected y spindle adapted to rotate the bobbin.

and rotation imparted to the latter.

The naturemof the invention is fully described below, and illustrated in the aecompanying drawings, in which-m Figure l is a central vertical section of a portion of a bobbin to which my invention has been applied removed from the spindle. Fig. 2 is a View in elevation of a portion of a Fig. 3 is an elevation of the spindle with the bobbin in position thereon and shown in vertical section. Fig. 4: is an enlarged section taken on line 4 4, Fig. 3.-

Similar letters of reference indicate corresponding' parts.

a represents a spindle provided with the rigidly-attach`ed whirl 7), from which there extends upward the sleeve c, which is formed with the annular platform d, upon which the head of the bobbin is adapted to rest. A collar g is rigidly secured to and around the spindle at a short distance above the platform.

The collar and platform are provided with suitable sockets, in which engaging or clutch ing blades /t are pivotally held in a vertical position, the pivots being" so located as to bringthe axial or pivotal line in each bla-de toward its rear edge, which is provided with a small extension or projection 71,. The blades /t are arranged around the spindle to point in the same direction aroundthe circle and lie in an approximately tangential position with relation to the spindle, the projections acting as stops against the spindle and holding the blades in the said position. The greater portion of each blade, therefore, extends outward beyond its vertical axial line.

Secured to the bobbin e is a ferrule, the larger portion. 7e, of which lines the inner surface of the wall of the chamber f within the head of the bobbin and is provided with a series of vertical imvardly-projecting ratchetshaped teeth l. said teeth facing the same di rection in which the clutching-blades point. This ferrule preferably extends under the end of the bobbin at y) up and around it at fr, the part y) resting on the platform d and the ferrule being rigidly secured to the bobbin by friction or in any other suitable manner.

Then rotation is imparted to the spindle, the outer and broader portions of the clutching-blades y; swing outward by reason of the rotation of the blades produced by centrifugal action until the outer edges of the blades come into contact and engagement with the teeth l, as illustrated in Fig. 4i, when they thereby impart rotation to the ferrule, and hence to the bobbin.

The blades may be thickened at their outer ends, if desired, and their engaging corners-- that is, the outer advance corners-are preferably formed, at right angles in order to fit into the teeth of the ferrule. Thus a positive engagement of the bobbin is made by horizontal1y-rotating clutching-blades, which, with their axial lines, are between the spindle and the bobbin.

It is evident that the ferrule, while primarily providing a means of engagenient for the clutching-blades with the bobbin, serves also to materially strengthen the bobbin.

Having thus fully described my invention,

IOO

what I claim, and desire to secure by Letters Patent, isv

l. In Combination with a rotatable spinningspindle, and clutching-blades pivotally disposed between the spindle and the bobbin; a removable bobbin provided with an inner lining' or Jerrule formed with inwardly-projecting teeth, whereby said blades are by the centrifugal force derived frornthe rotation of the spindle, rotated or swung into engagement with said teeth, thereby making connection between the spindle and the bobbin.

2. In combination with a rotatable spinning-spindle, and clutching-blades pivotally disposed between the spindle and the bobbin; a removable bobbin provided on its inner surface with inward projections, whereby said blades are by the centrifugal force derived from the rotation of the spindle, rotated on their own aXes into positive engagement with said projections, thereby making connection between the spindle and the bobbin.

3. In combination with a rotatable spinning-spindle, and clutching-blades pivotally disposed between the spindle and the bobbin; a removable bobbin provided with an inner surface thereof, whereby said blades are by the centrifugal force derived from the rotation of the spindle, rotated or swung into engagementwith said teeth, thereby making conneotion between the spindle and the bobbin.

In testimony whereof I have signed my name to this speeieation in the presence of two subseribng witnesses.
