l s claims.

- `of a balanced construction which' will allow great- 4er selection of means for accomplishing the'dee sired tension on the different rolls'.

` A still further object of this invention is the provision of a construction by which each pair of back rolls may be weighted independent of the next pairof rolls. l

` Witlrthese` and other objects in view, 'the invention consists of certain novel featuresof construction, as will be more fully described, and particularly pointed out in` the appended claims. "In the accompanying drawings:

Fig. lis a sectional view through thespinning frames with a commonweighting means 'extending between the back and-front rolls' of the units.

Fig. 2 is a section taken on line 2--2 of Fig. 1.

Fig.` 3 is``a` topiplan' view of a fragmental portion of one unit of the spinning `frame at substantially line 3--3 of Fig. 1, showing the connection of the hanger for the weights tothe rolls.

Fig. 4 is a perspective view of the hanger for the weight for the ba'ck pairs of rolls.

In equipping spinning frames with the construction disclosed in my co-pending application above referred to, I nd that in some makes of frames the traverse motion shaft isso located as to prohibit the use of weighting means such as disclosed in said application upon certain pairs of rolls, and in order to avoid the necessity of providing a different tension on these rolls and at the same time to individually weight each pair of back rolls, I have provided a yoke which may be suspendedfrom each pair of back rolls, having arms so located as to lie in planes at either side of the front roll weight extending between the frames, and in this manner I may distribute the 'weight in two parts to provide a construction which will be uniform in appearance and of better balance, and one in which the traverse motion shaft will not interfere with the weights, regardless of the type of machine used; and the yfollowing is a detailed description of the present embodiment of this invention illustrating the presults maybe accomplished.

i With reference to the' drawings, 10 designates the base for a pair of back-toeback` spinning units 11 and 12, and being identicala description of one will suilicefor both. i l f `Each unit consists of front pairs of rolls 15 and 16, intermediate pairs `of rolls 17 and 18 and back pairsoflrolls 19 and 20. There is also provided on each frame, -braker draft rolls 21 and 22.

areprovided in pairs witha reduced portion 23 therebetween. The front upper pairof rolls designated 15 are tensionedthrough a hook 24a-engaging the reduced portion 23 to which a weight 26 is connected by a link 25 whichweight extends across to the opposite frame and serves to tension a front pair of rolls of the opposite spinning frame `unit in'a similar manner;

The upper back rolls are similarlyarranged in pairs, and I have provided a hanger or zfork 27 with a hook 28 to engage the reduced portion 23 between the pairs of rolls 19. This hanger member is shaped to providea pair of arms 29 and 30 and is offset to clear the `lower back roll 20. The arms 29. and 30 are located` in vertical planes at either side of the front roll weight 26 with links 31 and 32 extending through openings 33 and 34. in the support 10 to engage weights 35 and 36 havferred means by which these advantageous re- ,y The lower rolls of each of the pairs described are suitably driven, while the upper rolls .of each pair ing a laterally thin and generally rectangularly cross-section and located on either side of the front roll Weight 26. Each of these weights 35 and 36 extend across from one spinning unit to the other unit so as to apply tension to a pair of back rolls on each of the units.

The arms 29 and 30 are provided with hooks 37 to engage the eyes 38 of each of the links to which they are connected, so that if it is desired to remove a back roll from position it is merely necessary to unhook the eye 38 from the hanger hook 37 and permit the weight to be lowered and the hanger 27 lifted from the back roll. In order that the weight may be supported during removal of the back roll and thus avoid the neces-,fsity of threading the link 31 or 32 through its opening in the base 10, I provide a washer 40 of a suicient area to prevent passage of the eye 38 through the opening in the base board, which in turn limits the movement of the link 31 or 32.- and retains the eye in a position from which it` may be readily lifted to again engage the hook 37 in replacing the parts in operative relation.

By this arrangement the structure retains all of the advantages as set forth in my co-pendingA application above referred to, and it additionally provides for individually Weighting each pair of upper back rolls and a structure which will not interfere with the traverse motion shaft in any of the usual types of machines.

The foregoing description is directed solely towards the construction illustrated, but I desire it to be understood that I reserve the privilege of resorting to alli the mechanical changes to which the device is susceptible, the invention being defined and limited only by the terms of the appended claims.

I claim:

1. In a spinning frame, groups of aligned front,

intermediate and back pairs of draft rolls, independent means below said frame forweighting the upper rolls of each front pair of rolls, ahanger suspended from an upper pair of' backrolls havL ing arms straddling the front Weighting means,` and Weights secured to the-arms for weighting saidback rolls.

2. In combination aI pair ofy spinning units, eachliaving groups of aligned'front',.intermediate and'y backfpairsfofdraft rolls, common Weighting meansI for applying pressure tothe' upper rollsof a pair of front rolls on each'spinnngunit, anda fori: suspended fromr one pair of 'upper backr rolls on=each1f`rameiand a pairrof: commonweights eX- tending between the members of each'framefor weighting' said back' rolls.

31. In combination a@ pair of spinningV units, each` havingy groups of aligned front, intermediate and back` pairs of draftrolls, common Weighting means for applying pressure'to theupperfrolls of a pair of front rollson eachispinning. unit', and a fork suspendedifromione pair. ofiupper back. rolls on eachframeianda pair. of commonV weights exteniding between.l the memberso eachi frame` for weightingsaid back rolls', saidV Weights being 1ocated on=oppositefsides of the'front roll Weighting means.

4. In combination: a pair of spinning,l units positioned backk tor back, eachv having pairsy of front and back" draft, rolls, weights for applying pressure tok said draft rolls, one weight being common to one pair ofk front. rolls in each unit, a member suspended from. av pair of back draft rolls in each unit, a pair of weights suspended from said members for Weighting said back rolls, said Weights being located on opposite sides of the common weight.

5. In combination, a pair of spinning units positioned back to back, each having pairs of front and back draft rolls, weights extending from one unit to the other, one weight being common to one pair of front draft rolls in each spinning unit, and a member suspended from each pair of back draft rolls on each frame and a pair of common Weights suspended from said members for weighting. said back draft rolls, said Weights being located on opposite sides of the common weight.

6:. In aspinning machine, a pair of spinning units positioned back to back, each having pairs of front andl bank draft rolls, separate Weights extendingzfrom one unit to the other, one Weight being common to one pair of draft rolls in each unit and the other Weights# being' common to another pair of draft rolls in each unitsaid last mentioned Weights being located on opposite sides of the single Weight 7. In combination, a pair of spinning units positioned back toback, each having pairs of front and back draft rolls, Weights for applying pressure to said draft rolls, a Weight being common to one pair of front rolls in each unit, means common tothe two-units and independent of the front weighting means for Weighting the upper roll of saidv back pair of draft rolls and located on opposite sides of the Weight for said front rolls.

8. In' combination, a pair of spinning units positioned back to back, each having pairs of front and back draft rolls, weights for applying pressure to` said draft rolls, a Weight being' commontdone pair of front rolls in each unit, means common to the two units and independent of. the front weighting` means for weighting the upper roll of said back pair of draft rolls andlocated on opposite sides of the weight for said front rolls, said common weights being located in the same horizontal plane.
