Description

UNITED STATES PATENT OFFICE JACOB H. SAWYER, OF LOWELL, MASSACHUSETTS.
IMPROVEMENT IN SPlNDLE-BOBBINS.
Speciication forming part of Letters Patent No. l76,359, dated April 18, 1876 application filed September 11, 1875.
To all whom it may concw:
Be it known that I JACOB H. SAWYER, of Lowell, in the connty of Middlesex and State of Massachusetts, have invented Improvements in Spindle-Bobbins, of which the following is a specification:
-yarn is not allowed to extend quite to the grooved portion of the bobbin, for should the fillin g get into this groove the bobbin-catch, which nust enter this groove, will break the yarn and make it necessary to stop the loom, and in this way much time as well as yarn is lost, and besides this loss, the quantity of yarn that can be put on such a grooved bobbin is limited by such groove, for the y arn cannot be wound down at the base of the bobbin as far as it. otherwise could be wound were the groove unnecessary, and by winding the yarn lower down on the bobbin, the yarn may be built out farther and the bobbin may be made to contain very much more yarn, which is a great desideratum, and prevents waste of time in stopping machinery.
This invention consists in a bobbin provided at its base with an opening larger than the States granted to Daniel Wright November 2,-
1875, and numbered 169,504 and 169505, to which reference is made.
In the drawings, a a are the bobbin-bearings for the sinall or outer or upper end of the spindle, and b b are the spindle-bearings at the lower or large end ot' the bobbins, (but,
instead of these bearings b, plug-bearings c may be used.) An opening, d, larger than the spindle-bearings, is made in the base of the bobbin, and'within and near the end of this enlarged opening and within the bobbin, is a groove, e, adapted to receive a catch whi h extends through the opening d, and engages the groove.
l have shown several different Varieties of bobbins, all of them well known, and instead of those shown I might use any other bobbins of well-known shape, both externally and internally, so long as such bobbins are provided with niy improvement, the openings d e or their equivalents.
I claim- A bobbin provided with spindlc-bearing, an opening in its base larger than the spindlebearing, and a groove in the interior of the base of the bobbin between the enlarged opening at its base and the spindle-bearing, substantially as described.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
