Letters Patent No. 112,103, dated February 21, 1871.

IMPROVEMENT IN DRIVING MECHANISMS FOR ROVING, SLUBBING,AND OTHER MACHINES.

The Schedule referred to in these Letters Patent and making part of the same.

We, ALFRED WILoooK, RICHARD ROBINSON, and FREDERICK WILcocK, all of Rochdale, in the county vof' Lancaster, Kingdom of Great Britain and Ireland,

have invented Improvements in Machinery-'or Ape paratns to be employed forpreparing c cttonand other librous substances for spinning, of which the following is a specilication.k l

This invention applies to the machines knownwas slubbing, intermediate, and roving frames, andto such other machines used in preparing cotton and other fibrous substances as are provided with one or more conical pulleys o r drums, for the purpose of gradually diminishing the speed of the bobbins as their Idiameter increases. l

In machines of this class it is necessary for the rollers and the bobbins to start and stop simultaneously, otherwiseimperfect work or breakages will occur; tnat is to say, if the bobbins stop before the rollers, or start after them, the yarn will become curled or snarled; and if the rollers stop before the bobhins, or the bobbins start before the rollers, the yarn will be stretched, and eitherlthin places or breakages will occur; and in order to prevent this the strap which drives the cone from the first shaft must be in a complete state of tension, or perfectly tight around the two pulleys, and it has` been found by experience that the strap always gets more or less slack by use, and, hence, im-

perfect or damaged work results.

In order to obviate' this defect and to cause the cone which drives the bobbins to start and stop simultaneously with the rollers, we'use an auxiliary pair of pulleys, (one on each shaft,) and we pass an endless strap around these two pulleys, and it is found that this auxiliary strap assists the cone-strap in stopping and starting, and causes the bobbins to stop and start simultaneously with the stopping and start-ing of the rollers, and thus prevents either the stretching or curling of the yarn.

In order to enable others skilled in the art to make and use our invention, we will now proceed to descibe its construction and operation.

On reference to the accompanying` drawing- Figure l shows the way, in which we propose to apply our invention to old flames or machines already in use. v

It ce is the top cone-shaft, and

d d, the ordinary cone-strap, which is movable over the surface of the cones, by m'eans of the strap-fork or guide,-'iu the usual manner, so as to gradually diminish the speed Aofthe bobbins.

Upon the top'cone-shaft or driving-shaft a, a we fix an auxiliary pulleye c, about the diameter of the larger end of the cones, and u pon the bottom coneshalt b b we x a second smaller auxiliarypulley, j f, about the same diameter as the smaller end of the cones, and round these two pulleys we pass the auxiliary strap g y. These auxiliary -pulleys may, if preferred, be made in twoparts, and bolted together so as to be applied without removing the shafts liom the machine.

In fitting up anew l'rameor machine, we prefer to cast or form the auxiliary-pulleys in one piece with the cones, as shown at Figure 2.

It will, of course, be evident that the same eiect4 might be produced without using the auxiliary puly leys by placing an auxiliary strap on one end of the cone-pulleys themselves, by making the cones a little longer, or shortening the traverse of the cone-strap, as shown by the dotted lines in iig. 1; but we prefer the use of the auxiliary pulleys,v as before described.

This auxiliary strap g g, as above mentioned, as sists the stopping and starting of the bobbins, causing them to stop and start at all times simultaneously with the rollers, but, being narrower than the couestrap d fl,'slips on the pulleys when the machine is in work, and allows the latter to regulate the speed of the bobbins.
