IMPROVEMENT IN JACK- SPOOLS Specification forming part of Letters Patent N o. 1 78.335, dated June 6. 1876; application filed December 27, 1875.
To all whom it may concern:
Be it known that we, MATHEW H. SCOTT and JOHN DAVIS, both of Providence in the State of Rhode Island, have made certain new and useful Improvements in J ack-Spools and we do hereby declare that the following specification, taken in connection with the drawing making a part of the same, is a full, clear, and exact description thereof.
Figure 1 is a section of ajack-spool, with a portion broken out to show our improvement. Fig. 2 shows the bearing and key detached. Fig. 3 shows another method of locking.
The object of our invention is to produce a jack-spool which shall bemore durable than those now in use, and at the same time less likely to damage the yarn.
The jack-spools now in use have their heads androllers attached or held together by the bearing or arbor A, which is provided, near the center, with a shoulder, B, and, at its inner end, with a screw-thread, O. The shoulder B brings up against a.circular metal plate upon the outside of the head D, and the head and roller are brought firmly together by means of a nut, G, upon the inner end of the arbor A,-which is placed within a hole in the roller E, which is subsequently plugged up.
The frequent rolling of the spools over the floor, as well as their use in the machine, soon works the hearing A loose, and allows it to come out, which lets the spool drop, and causes much damagelto the yarn.
' In our invention we flatten that end of the hearing A which has the screw-thread, and make a key, F, which is semicircular upon the back, and flat uponits face, and is provided with a slot of a suitable size to allow it to drop over the flattened end of the bearing. After the nut is turned up in the usual way the key is placed over the end of the hearing A, and the hole plugged up, as heretofore.
It will now be readily seen that it will be impossible for 'the hearing A to become released from the nut, and thus allow the roller to fall to the floor.
, What we claim as our invention, and desire to secure by Letters Patent, is- I In a jack-spool, the combination of the hearing A, having its end flattened and threaded, as described, nut G, and slotted key F, substantially as and for the purpose specified.
MATHEW H. SCOTT.
