IMPROVEMENT IN COPS FOR SEWING-MACHINES.

S;ieciiicafion iin-ming part of Letters Patent N0. 10,128, dated April 4., 135|.

.mak-ing a part of this specification, in which- Figure I is a View of a cop or bobbin as taken off the winder 'or machine by which it is made. Fig. II is a View of a cop or bobbin as it is placed in a shuttle; -and Fig. III is a view of a shuttle thus containinga cop or bobbin in its race, with the end of its thread projecting; and Fig. IV is a cap so constructed as to draw lits thread from the side thereof.

v @More particularly: In Fig. I, A is the cop orbottom. It is spirally wound. B isthe internal end ofthe thread emerging from the inside thereof by a hole at one end. It 'is a spirally-wound mass of thread recurving at each muh-alternately, until it is wound large enough to fill the shuttle, when a few circular windings are given upon the whole mass preparatory to securing this end of the thread, and then by a loop-knot or other similar and equivalent Inode the external end of the thread is fastened.

The Inode of constructing this cop, bobbin, or mass of thread is as follows: I take a suicient quantity of thread--be the article I desire to use, silk, linen, cotton, or otherv Inaterial-and I'attach it to the distal end or protruding end of the spindle, on which I wind the cop. -I then revolve the spindle a few times, which puts on the` spindle,nearlycircular windings in immediate contact with the spindle; and whenthese nearly circular windings are about the length ofthe cop I wish to complete, I then lay the thread in a guide and continue revolving the spindle, which tends to give circular windings, while the guide tends to move the thread parallel to the lon-4 gitudinal axis ofthe spindle. The combined action, therefore, of the spindle and guide is that' the cop is wound spirally and to the length to which the guide is set or gaged. A

recurve is of course made somewhat abruptly at each end by the alternating or reciprocating ternal end so that it may not slip and become` tangled.' I give this description because it best-describes the nature of the cop. -But in so doing the windings. nearly circular at first, are not essential, foi-if the spindle is rough enough so that the thread will not slip upon it, then the thread may be put into the guide without them. And as to the last circular vwindings,l they are not essential, as the end may be fastened by other means, as a little paste or glue; or a paper may be wound about the whole to preserve the shape and facilitate the operator of a sewing-machine while handling a quantity of cops, the'I last object being merely to secure the external end, and of the former to 'commenceY the corp properly;

but the combined actionof the spindle and guide is essential, or their equivalents, in orderto make a cop spirallywound, and drawing or feeding out its thread from the inside thereof until it exhausts the whole cop. The

machine by which this is done, not being claimed in this specification, is not figured nor described; but the cop thus Vmade is described, that the use of it in sewing-machines may be described not only,but claimed.4 It is believed that the flow or feeding out of the thread of this cop is steady and even, and is of `great utility in making tension on the shuttlc-thread, as well as a very convenient and useful Inode of placing thread in the shuttle.

By Fig. II, I design merely to show a cop which draws or feeds out or pays out its thread from the inside thereof lin a shuttle, thus exhibiting further its use in sewing-machines. C is the shuttle, with a cop lying in it; and I) is the internal end of the cop passed through a hole in the side of the shuttle, a series of holes inthe side of the shuttle near D, or a friction-needle, or other means making the nec- 5 essary tension on the thread, which means, not being claimed in this specification, are not fignrednorl described, said tension, meaning the 0f the cop there are inany varieties and tightness given to the thread 1after it has left the oop, the iiow or feeding out of the cop being uniform and even.

Fig. III is a shuttle-race, with a shuttle 1ying in it. E -E is the race; F is the shut-tie, with the -internal end of the eopthread projecting from one of the holes in the side of the shuttle. .G is the point or piace Where the needle plunges of the sewing-machine. The action and use of the shuttle and race is familiar to those skilled in sewing by machinery, to which art it appertains. The object of this. gnre is further to exhibit the use of the cop l in sewing-machines as connected with niaehines using a needle and shuttle, or their equivalents.

By Fig. IV, I show a variety of Fig. I. In it H is the oop and I the internal end of the Hiread, emerging by a hole in The side instead Of the end thereof.

equivalent-s, wound in a great variety of Ways. In describing` them, the main feature would ,be any and al1 masses, cops, 0r bobbins, drawing the thread from the inside thereof.

' What I elaim as my invention, and desire to secure by Letters Patent, is-

The use of a cop or bobbin Without spindle or spool, in combinationwith a shuttle, or what is equivalent thereunto, when the thread is drawn or fed out from the inside of the cop or bobbin, by which means l secure an uni-4 form tightness-or tension on the cop or bobbin thread as it is ydrawn or fed out from the shuttle, as described.
