DRIVE-MECHANISM non 'rwis'rme AND srmmne FRAMES.

I Application med narchjzaieas. Serial meaas'sa I To all whom it concern:

Be it known that I, I'IERBERT 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, Case B, ofwhich the following is a specification.

This invention relates to I twisting and spinning machines and more particularly to spindle driving mechanism therefor. The spindles of such machines are usually driven by means of endless bands which pass about a drum or driving pulley. To'secure smoothness of operation as wellas to prevent loss of time in replacing worn or broken bands it is desirable to employ-integrally continthereof.

uous or jointless bands, preferablymade by a. weaving or similar operation. Such bands cannot be applied to the machine as usually arranged and the object of the pres. ent invention isto provide an arrangement of parts which makes possible the employment of such continuous and jointless driving bands.

1 In the accompanying drawings a pre-' ferred arrangement is illustrated by way of example, together with certainmodifications In the drawings: Fig. 1 is a fragmentary plan view of a spinning ortwisting frame of usual construction having the present invention ap plied thereto; I r 1 Fig. 2'isa verticalcross' section on aline such as 22 of Fig. 1; I Fig. 3 is a fragmentary vertical section on the line 3-3 of Fig. 2, certain parts being omitted; Fig. 4 is a plan and'Fi'g. 5 is an end elevation showing diagrammatically a -mod.i-.

. cated at 1, 2, respectively. "These side'rails support series of spindles, certain of which 1 areindicated by way of example at 3, 4;, ,5,

6; 3, l 5 6, respectively. The several spindles are provided with whirls '7 in the usual. manner. Transverse members 8 are arranged at intervals longitudinally of the frame, and] support spaced brackets 9,10.

The brackets!) are provided with journal bearings for a longitudinally extending shaft 11, while the brackets 10 support journal. bearings for a shaft 12. The shafts 11 and- 12 are provided withpulleys 13, 14 at a con venlent point, perferably adjacent to one end of the machine, and a'belt1'5 engages these pulleysand compels them to. rotate in l. the same direction. The shaft 12 is alsof furnished with a pulley 16 for a drive belt, (notshown) receiving its power from any suitable "source. Spindle. driving pulleys such as11,-12,111 ,12 are mounted upon the. shafts 11 and 12, the- pulleys 11 and 12 turning substantially in the plane .de

fined by spindles S-and 5, while pulleys 11 and 12 turn in a plane defined by spindles A bracket 17 is' secured to each of the several transverse members 8 and these brackets are furnished with vertical guide openings forthe reception of slide plates 18.

Each of these plates is provided with a 5 bracket 19 at its upper end which carries a bearing 20 for the shaft 21 of a pulley such: as 22 or 22 Integrally continuous endless bands such as 23, 23 partially encircle v,

Preferably each band partially encircles or embraces the whirls of two spindlessuch as 3 and 4' on one side of the machine and correspond- .7 ing spindles 5 and 6 on the other sideof the machine, a single bandthus serving todrive' four spindles, although it is contemplatedthat the band may embrace but a single whirl at either side of the "machine if de-- sired. Each band ismade of such'alength that when positioned as above described, the

the weight of'the-pulley 22 and the slide plate 18 is supported by theband so that the the drive pulleys. In a similar mannereach.

In placing the: Joand inq-position, it .is:

merely necessary to pass it over the spindles at opposite sides ortthe machine and:

then by lifting the guide pulley to pass one run of the band-beneath such pulley so that the weight ot' thexpulley is supported by I the band. then? the band requires replacement,

"the guide :p'ulley22' is litted slightly and the band unay be removed without diificulty. It

ist-hus possible'to employ .bands which are woven-continuouslyuand which may :be put 1 in position without rsplicing. The arrangementshownin Figs. 4i'and 5 is generally .similar'to that above described.

In this case the :spi'ndles 31, 32; :are driven by a band 85 aone runof which passes over the :adj acent surfaces of drive pulleys v36 and 37-:a'nd under-atension pulley 38. .The :ten-

ln' Figs. 8 and 9 a modified arrangement is shown inwvhich the side frame anembers of the machine :are designated 101, 102xrespectively. Upon these side "frames spindles 300,3500 respectivelyqare mounted in usual manner. .Longitudinally extending *driiveshaiits 3111', 112 are j ournaled: in suitable supare arranged corresponding-to each :pa'irrof oppositely -d1sp0sedspindles, the-Pulleys being: d sposed substantially in" the vertical A bracketw509 correspondingto each pair of pulleys 111 112 is-securedsupon longitudi nally extending rods or bars 80 and lever 510=-is-wpivotally mounted at the, point 520 of eachofqsaid-.bracl;ets. The :free extremities of these levers-are weighted in: any suit run passes. downwardly over the pulley 111 beneath the guide pulley 222 and over the pulley .112. The guide pulley 222 thus servesto tension theibeltiand keep it in operative relationship to the driving pulleys and the spindle whirls. lfi ith this arrangement I it is possible as in the previous constructions to applyan, endless belt to the spindles and driving pulleys without the necessity I of joining the endsof the belt aiterit has been passed about the several operative elements.

In Fig; 10 a-t'urthe'r modification is shown 'in which the driving pulleys. 111 and. 112

are indicated in dotted'lines andthe -guide ulle 222 is shown as 'ournalednnon a l stub shaftQlO carried at. the upper end of Q a link 81 pivoted 'at-its lower end at the point 82fto the lever 510 Thisleve'r is fulcrumedat the point' 520 upon :anysuit ablebracket, not shown,-and is "preferably weighted :at its free extremity 'as' indicated at 530 'lVith this arrangementthe pull upon 'the belt ?is exerted -in a :substantially vertical direction without lateral component.

In Fig. :11 afurther modification is shown in which thetension of guidewpulley 222 is shown as :journaled upon a stub shaft carthe axis ofthe tension pulley is disposed in' a vertical-plane :intermediate the vertical planes of the shafts of the dri'veapulleys so that "its facts simultaneously to press the driving band into contact'withitheperiph- Hal-surfaces of each of the i drive pulleys. It 'isfialso clear that, by employing mechanism such as described it is possible to apply an integrally continuous endless' b'and or to remove it without difficulty or loss of time. Such bands provide azanueh smoother and more uniform means 'for'driving "the spindles than the usual bands'rhavingjoints, while the application ot-sbands of this kind can .be-performedmuch more expeditiously than when the bands must be spliced as is the usual practice. While certain specific arrangements .havebeen shown herein Ins desirable, 'it is evident thato'ther and equivalent arrangements may well be employed without departing from the spirit of the present invention.
