PATENT OFFICE.
-WILLIAM F. DRAPER, OF HOPEDALE, MASSACHUSETTS, ASSIGNOR TO SAWYER SPINDLE COMPANY, A CORPORATION OF MAINE.
YARN-SPINNING APPARATUS.
SPECIFICATION forming part of Letters Patent No. 760,973, dated May 24, 1904.
Application filed March 9, 1904. Serial No. 197,227. (No model.)
1'0 0,66 whom, it nutty concern.-
.Be it known that 1, WILLIAM F. DJRAPER, a citizen of the United States, and a resident of Hopedale, county of Worcester, State of Massachusetts, have invented an Improvement in Yarn-Spinning Apparatus, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.
This invention relates particularly to yarnspinning apparatus wherein the yarn-receiver or bobbin is connected with the spindle during the spinning operation by clutching members carried by the spindle and which are forced outward by centrifugal action when the spindle is rotated. At such time said members engage the walls of a chamber in My present invention has for its object the production of means whereby when the centrifugallyacting clutch device is in operation an additional and positive engagement between such device and the bobbin will be effected, automatically.
The various novel features of my invention will be fully described in the subjoined specification, and particularly pointed out in the following claims.
Figure 1 is a longitudinal sectional'view of a yarn-receiver or bobbin embodying one form of my invention shown in operative relation with a spindle provided with a centrifugally-acting clutch device. Fig. 2 is transverse sectional view on the line 2 2, Fig. 1. Fig. 3 is a longitudinal sectional detail of the head end of the yarn-receiver or bobbin,
shown in Fig. 1; and Fig. 4 is a transverse sectional v1ew similar to Fig 2, but showing a modification to be referred to.
In Figs. 1, 2, and 3 the yarn-receiver or bobbin 1, of wood or other suitable material and shown as having annular projections or rings 2 externally mounted on its head 3, is provided with the usual central bore 4 to receive the spindle and with a chamber or socket 5 at the lower end of such bore within .the head 3. The spindle A, whirl W and its sleeve W, and the centrifugallyacting bobbin-clutching members 5 may be and are substantially as in the patent, No. 7 34,747
referred to, the sleeve W being shown'in.
- load on the bobbin be large and heavy, however, there may be a tendency of the bobbin at times to slip, particularly if the spindle speed be decreased, and in my present invention I provide means to effect a positive driving connection between the spindle and bobbin operative when the clutch is in op' eration.
In Figs. 1, 2, and 3 I have shown a very simple form of positive connection-via, a radial projection 6 on the wall of the bobbinchamber 5 to be engaged by one of the upright edges, as b, of a clutching member when said members are moved outward by centrifugal force. This projection 6 is formed by the inner end of a pin 7, driven through the head of the bobbin, so that its inner end projects into the chamber, a very slight projection being sufficient for the purpose. Rotation of the spindle being in the direction of the arrow, Fig. 2, it will be manifest that the leading upright edge of any one of the clutching members I) will by engagement with the projection effect apositive driving connection between the bobbin and spindle when the clutch is in operation. Usually one projection will be sufficient; but more may be used, if desired, operating in a similar manner.
Instead of forming a projection as herein before described the projection may be made as an integral part of the bobbin by recessing its chamber-wall longitudinally. construction is shown in Fig. 4, the wall of the chamber 5 being provided with three symmetrically-arranged recesses 8, thereby presenting a like number of longitudinal shallow ribs or projections 9. The centrifugal force acting upon the clutch members I) when the spindle rotates throws them outward into the recesses, and their upright leading edges engage the projections 9. The recesses are preferably made to correspond with the number of clutch members, or they are symmetrically disposed to prevent even a slight irregularity in the disposal of the load upon the spindle.
My invention is not restricted to the precise form and arrangement of positive driving connection shown and described herein, for the same may be varied or changed without departing from the spirit and scope of my invention so long as the positive driving connection is constructed and arranged to act by or through the operation of a centrifugallyacting bobbin-clutch.
- driving connection between it and the clutching means.
2. A rotatable spinning-spindle provided with centrifugally-acting bobbin-clutching means, a removable bobbin, and means to effect a positive driving connection between the Such a bobbin and said clutching means by or through the operation of the latter.
3. A rotatable spinning-spindle provided with centrifugally-acting bobbin-clutching means, a removable bobbin adapted to be en gaged internally by said means, and a radial projection on the bobbin to independently cooperate with said means when operative and thereby effect a positive driving connection between the bobbin and the spindle.
4. A rotatable spinning-spindle provided with centrifugally acting bobbin clutching members bodily rotatable therewith, a removable bobbin chambered to receive and be frictionally engaged by said members, to effect rotation of the bobbin with the spindle, and a radial projection on the wall of the chamber to be engaged by the leading edge of a clutching member and thereby efiect a positive driving connection with the bobbin.
5. A rotatable spinning-spindle, a plurality of radially -movable and elongated bobbinclutching members bodily rotatable therewith, a removable bobbin chambered to receive and be interiorly engaged .by said members, and radial projections on the wall of the bobbinchamber to be engaged by the leading edges of said members, to form therewith a positive driving connection between the bobbin and spindle.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
WILLIAM F. DRAPER.
