DRIVE MECHANISM FOR TWISTING AND SPINNING FRAMES.
Application filed. February 19, 1923. Serial No. 619,793.
To (4U w/iommay concern:
Be it known that I, Hnnnicirr G. BEEDE, a citizen of the United States of America, and resident of Pawtucket, in the county of Providence and State of Rhode Island, have invented new and useful Improvements in Drive Mechanism for Twisting and Spinning Frames, of which the following is a specification.
This invention concerns twisting or spinning frames and relates more particularly to improved spindle driving means therefor.
The spindle whirls are usually driven by means of endless bands or belts, but as it is impossible to pass an endless band about the driving drum or pulley due to the presence of the shaft upon which the latter is mounted, it is usual to make the bands from straightstrips, splicing the encstogether after the band has been passed about the drive shaft. This splicing of the bands consumes considerable time during which the spindle must remain idle, and at best, such a spliced band is not as satisfactory as an integrally continuous or jointless band would be. I
The principal object of the present invention is to provide a drive mechanism for the spindles of twisting and spinning frames of such character as to permit the employment of endless woven or other integrally continuous bands for driving the spindles.
In the accompanying drawings a preferred arrangement of parts, together with certain modifications thereof, is shown as illustrative of the various specific arrangements in which the invention may find embodiment. c
Fig. 1 is a fragmentary plan view of a spinning or twisting frame of usual construction having the present invention applied thereto;
Fig. 2 is an elevation partly in section of the parts shown in Fig. 1;
Fig. 3 comprises a diagrammatic plan view and a diagrammatic end elevation respectively of a modified form of apparatus; and
Fig. at comprises a similar diagrammatic plan view and end elevation of a further modification.
Referring to Figs. 1 and 2, the longitudinal frame members of the machine are indicated at 12 respectively. A series of transverse supporting members such as 3 extend between the frame members 12 and these supporting members 3 serve to support journal brackets for a driving shaft 4. This shaft is provided at one end of the machine with a pulley 5 fora dr ing belt and with a series of spindle driving pulleys 6. shaft '4' is mounted in suitably supported hearings and on this shaft a series of loose guide pulleys 9 are mounted, these pulleys being arranged in the vertical plane of the drive pulleys 6. Upon suitable supporting means 10 hell crank levers 11 are pivotally supported. One arm of each lever extends upwardly and is provided with a stub shaft 12 upon which a tension pulley such as is mounted. The tension pulleys 13 are arranged in the planes of the corresponding drive pulleys 6. The bell crank levers 11 are also furnished with lateral arms 14 to which weights 15 are secured, the arrangement being such that the tension pulleys 13 tend to approach the respective drivepulleys. The side frame members 1 and 2 are provided with series of spindles such as 16, 17 respectively, each spindle being furnished with the usual whirl for driving it. An endless and jointless band such as may he formed by a weaving or other textile process partially encircles spindles at each side of the machine. As indicated in Fig. 1 the band may engage a single spindle at each side of the machine, or two or more spindles at each side, as may be desired. This band or belt comprises an idle run 20, and a driving run which passes beneath the pulley J as'indicated at 21, over the drive pulley 6 as at 22, and beneath the tension pulley 13 as shown at A3. Similar bands or belts partially encircle the next adjacent spindles or groups of spindles and are caused to eugage the proper drive pulley 6 by passing beneath the corresponding guide pulley 9 and tension pulley 13.
In operation, the weight 15 serves to press the tension pulley into contact with the driving run of the band, thus maintaining driving engagement of the band with the driving pulley. It will be observed that this band does not completely enclose or encircle either the shaft 7 or the driving shaft 4 so that it is possible to apply and remove the band without splicing or sever ing the same. A continuous and jointless band may thus be employed so that the operation of applying the band to the machine is greatly simplified and the time consumed for the operation is decreased. Furthermore, the tension pulley exerts a constant pressure upon the band which keeps it in proper operative condition so that it is unnecessary to take up the band manually and the efficiency of the band is con tinuously maintained at its highest point.
In Fig. a slight modification is indi cated in which spindles 30, 31 are snown at opposite sides of the machine, the driving pulley being arranged intermediate such spindles, while a guide pulley 33 is mounted to turn about a fix d axis in t ie plane of the driving pulley. A movable tension pulley is also arranged in the same plane,
being or rice upon a sliding bar or frame 35'mounted in a support This tension pulley is normally urged toward the drive pulley by means of a bell crank lever comprising the vertical arm 36 which engages the outer end of the slide member this lever being pivoted at the point- 38. The opposite arm 39 oi the lever is furnished with a weight whose tendency is to move the pulley tow--'l the pull 32. A driving band 4:0 e the spindles 30, 31, passing over the guide pulley 33, beneath the drive pulley 32, and over the tension pulley This belt or band 40 may also be of continuous type without oint and capable of application to the spindles and drive pulley in a manner similar to that previ usly described.
in Fig. l: spindles l l0, 4-1 are shown as arranged at opposite sides of drive pulley In this case the guide pulley 43 turns about a. fixed axis below the axis of the drive pulley and in the plane of the latter while the tension pulley id is ara ed to move transversely in any suitable manner and to turn about an axis above the axis of the pulley l2. A driving band or belt encircles the spindles d0, all, passing over the pulley 42 and about the pulley 43 and over the movable tension pulley id. In this case also an integrally continuous driving band 45 may be employed.
il hile certain specific modifications and arrangements have been described as desirable, itis to be understood that these are only by way of example and that the invention is capable of embodiment in other and equivalent mechanical devices.
I claim:
and the drive pulley, a movable support for said second guide pulley, and means normally tending to move said second guide pulley in a direction to press arun of the endless band into contact with the drive pulley.
2. A machine of the class described comprising a pair of spaced spindles, an endless band g uging said spindles, a dri e pulley intermediate said spindles, the axis of the pulley being outside of the band, a guide pulley mounted to turn about a fixed axis between one 01"- the spindles and the drive pulley, a second guide pulley arranged between the other spindle and the drive pulley, a movable support for said second guide pulley, and means constantly tending to more said supportwith its pulley toward the drive pulley, each of the guide pulleys 'ng said band and holding it in driving contact with the drive pulley.
A machine of the class described compris ng two rows of spindles, a drive shaft therebetween having a drive pulley thereon, an endless integrally continuousband partially encircling a pair oi spindles of each row and engaging the drive pulley, the oppositely moving runs of the band being disposed to one side of the drive shaft, a guide pulley mounted to turn about afixed axis between the drive pulley and one row of spindles, a second guide pulley mounted upon one arm of a bell crank lever, the axis of said pulley being between the drive pulley and the other row of spindles. and a weight upon the other arm of said bell crank lever constructed and arranged to; press the movable guide pulley into contact with one run of the band.
