liVlPROVEMENTlIN DRAWING AND TWlSTING-HEADS FOR SPINNING-MACHINES.

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

To all whom it may concern.'

Be it known that we, SAMUEL WQLAWEENCE,

PHILo WALDEN, and JOSEPH W. HUNTOON, ct' West Eaton, in the county of Madison, and State or" New York, have invented a new and valuable Improvement'in Spinning-Machines and we do hereby declare that the following is a full, clear, and exact descxiption of the construction and operation of the same, reference being had to the annexed drawing making a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1 of the drawing is an end view of our invention, showing the rotating disk and rollers attached;

Figure 2 is a Avertical cross-section;

Figure 3 is a vertical longitudinal section; and

Figure 4 is a horizontal partial section.

Our invention has relation to spinning-machines; and

It consists in the improved construction of vthe drawing and twisting-tubes, by which the mending or ysplicing of the broken slivers is facilita-ted.

The object is accomplished by forming a` longitudinal cleft entirely through the wall of the hollowv shaft, pulley, and standard.

It also consists in other details of constructionhereinat'ter. fully described.

The letter A of the drawing designates the hol-v low shaft through which the sliver passes;

B is the driving-pulley cast or keyed thereon,

and

C is the disk at the end of the shaft, towhichthe rollers are attached. f A longitudinal cleft, a, is formed in the wall of the shaft A, and extends` outward through both pnll ley and disk.

'The jouxnalestandards D D are cleft vertically, and it is apparent that, when the ssure of the rotating shaft is vertical, or in line with the elefts ot' these standards, a longitudinal opening is formed the entire length of' the shaft from the entrance E to the rollers. Hence, when in this position, the sliver can be introduced or spliced in a simple manner, and with-V out loss of time, by merely pressing the sliver or the broken endsthereof, down through the fissure into the hollow of the shaft. 'Usually a number of these rotating shafts are arranged in line and operated by.

a single band passing under each pulley.

Sometimes alternate bearing-pulleys are placed between the rotating pulleys B, for the purpose of increasing the surface of contact thereof with the driving-band.

In order to avoid the stoppage. of all the drivingpulleys upon occasion of monding a single sliver, each driving-pulley is provided with a stud, l1, and a spring-stop, c, is attached to the standard adjacent thereto.

By pressing the stop c inward, either driving-pulley may be rendered stationary, and the stud b is so arranged that, when in contact with the bolt of the stop c, the fissure a will be vertical, and in line with the clefts of the standards DD.

-Gr G represent the drawing-rollers, pivoted to the plates e e, which are attached to the disk by means of screws.

Either or both plates may be made movable, being guided' and regulated in its motion by slots an Iformed in the plate, and through which the attachingscrews pass.

Within the disk Cisa spring, 71, designed to keep the drawing-rollers pressed together.

The application of the spring-stop will cause the drawing-rollers to assume avertioal position. Their upper ends are rounded or beveled, to provide for the ready'passagc of the sliver between them. Their lower ends are Yprovided with spur-wheels k, the teeth vot which are somewhat beveled on the under side, to

the slot s of the disk, and serves to' form a bearing for the shaft ot the-wheel fu, through which motion is communicated to the ypinion ll `Rotary motion is imparted to the spur-wheel e by its movement around the stationary gear-wheel or trundle z attached to the adjacent standard D.

It is apparent that the spur-wheel v may be shifted A from one end of the slot s to the other, thereby causing the pinion l to'engage with the gear-wheel of the opposite drawing roller. here attained-in the simple means thus provided for reversing the motion ot' the drawing-rollers. f

object is to prevent the sliver from falling between the teeth of the gearing when the rollers are pressed vW hat we claim as our invention, anddesire to secure 'by Letters Patent, is
