IMPROVEMENT IN MODES 0F ADJUSTING BANDS ON HAND SPINNING-MACHINES;

Specification forming part of Letters Patent No. 47,685, dated May 9, 1865.

To all whom 'it may concern Be it known that I, DAVID B. (DETER, ofV

Batavia Station, in the county of Jefferson and State of Iowa, have invented a new and useful Improvement in Adjustingthe Bands on a Hand Spinning-Machine; and I do hereby declare that the following is a full and eX- act description thereof, reference being had to the accompanying drawings and the letters of reference marked thereon. v

The nature of my invenwtion consists in providing each of the uprights holding the two pulleys M and L at the end of the track with a screw, H, to pass through the rails-of said track, and nuts K and K to fasten-said screws, thereby allowing the pulleys to be adjusted to give the'necessary tension to the operating-` bands. I also widen the groove in pulley T, and severthe band O and fasten the two ends thus severed in the groove of said pulley with twosmall wooden pins. I then pass the'other ends of band O around the pulley T, in opposite directions a sufficient number of times to give the required length of run to the car, then over the` pulleys F and L, as shown in Figs. 1 and 2, and fasten them to the carin the usual manner.

To enable others skilled in the art to make use of my invention, I will proceed to describe its construction and operation.

I construct my handspinning machine substantially in the following mannerthat is to say, I take two pine rails; these I put together with three turned cross-ties, so as to `form a track for the car carrying the spindle, Sto., as seen in Fig. 2. I then set this frame upon four legs, as seen in Fig. l. I thenmake a wheel and place it on said frame at its rear end, as shown in Fig. l, as wheel E. To the axle of said wheel E I attach crank X. I then fasten rmly to the crosstie, im mediately in front of wheel E on said track, the uprights holding the pulleys S and F, as seen in Fig. l. Y n

Pulley T is three and one-half inches in diameter and one and one-half inch thick. It is placed between the main rails, forming the track over the end of treadle N, as in Fig. l. Its construction is more fully seen in Fig. 3.

I turn two wooden screws, H and H, one inch in diameter with heads two inches in di ameter. These I fasten to the end of the track by nuts K and K. To the heads of these screws I fasten the uprights carrying the pulleys L and M, as seen in Figs. l and 2.'

Treadle N is made of three pieces, framed together so as to reach from leg to leg under wheel E, the long piece (four feet eight inches) reaching from the legs to pulley T, the short piece, (two feet long,) with a crosspiece to hold it together, and awire, which constitutes its axis or center of motion, running through the treadleinto the legs. (See Figs. l and 2.)

The car carrying the spindle and head is provided with wheels for traversing the track, and is framed twelve inches long, two inches high, four and one-halt inches outside, and two and one-half inches inside. To the front of this car, by means of an iron prong three inches high, I fasten the spindle, and near the other end ot' the car I fasten a head, R, five inches in diameter, and place the car upon the track. (See Figs. 1 and 2.) y

There are three cord-bands. The endless band P passes over wheel E, then under pulley S, then once around the whirl'on the head It, then` over the pulley M, and then back under wheel E. (See Fig. l.) The course of band O is fully set forth hereinafter. The end less band z passes around the head R, and around the pulley on the spindle for giving motion to the latter. The pulley T is turned backward by a cord fastened to its axle and to the end of treadle N.

In the class of machines upon whichl mine is an improvement the uprights containing the pulleys L and M are Xed and immovable, being attached rmly to a solid cross beam between the rails of said track, aud band O is passed once around pulley T, so that when you attempted to operate the machine, if the band O was a little slack, it would slip on the pulley T, and of course the car would not move. it would bind where it passes around the whirl of the head R until the whole machine would be at nearly a dead lock.7 Now, in order to remedy these evils, I turn two screws, H and Hone inch in diameter and of sufficient length to pass through the rails of the track and receive nuts K and K. (See Fig. 4.) I make `the heads of these screws sufiiciently large to receive the uprights which carry the pulleys L and M and hold them flrmly there- If the band I is a little too taut,

,of adj ustin gbands.

The manner ot' arranging the band O on the pulley T is fully illustrated in Fig. and

, marked Enlarged plan of pulley.77

Now, the mode ot operation is this: When the machine is ready for use. as seen in Fig. 1, and marked side view,7 if the bands O or P, or both of them are either slack or taut, by slight turn of nut K you loosen screw H, so that you can adjust pulley L or M, or both of them, to produce the required tension of the band (r bands. Now, by aturn of the large wheel E, the car is run back and the end of treadle N is elevated, then by placing your foot on said treadle, the car carrying the These screws are passed 4through the rails so as to leave the heads and spindle is thrown forward to the endof the track and held there until you give the larg wheel a turn, which twists the yarn 5 then removing the foot from the treadle by another turn of the wheel the car is again run back, at the; same time taking up the thread on the spindle. My method of adjusting said bandsl tends'to produce and assists in keeping up a certain easy and uniform operation ot' said machine.

Now, what I claim as my invention, and desired to secure by Letters Patent, is-

The method of adjusting bands in spinningmachines by means of screws and 1'1u-ts,in combination with the manner of attaching the band to the pulley T, as and for the purposes described.
