Another object of the invention is the provision of weighting means which will permit of the running relatively close together that long draft spinning may be had.
Another object of this invention is to provide weights so arranged that the back and front rolls of the frame may be independently weighted or tensioned.
Another object of the invention is the provision of Weighting means for both the back and front rolls located generally in the same plane but which are arranged so as not to interfere one with the other.

the weighting means.
A still further object of the invention is the provision of a construction by which the Weights in the appended claims. In the accompanying drawings: Fig. 1 is a sectional view through the spinning machine showing two roller stands back to back with the weighting means below the breast beam of the machine.
Fig. 2 is a section on line 22 of Fig. 1.
Fig. 3 is a section on line the back roll disposed to partially receive the same.
Fig. 5 is a perspective View of the weights shown in Fig. 4.
Fig. 6 is a sectional view of one or are weighted by the direct application of weights, which, in some instances may be multiplied by levers in their action on the top rolls.
This invention deals more particularly with the latter type.
In prior machines where the nip rolls are sufiiciently large to apply their own weight, the nip rolls cannot be placed suificiently close together for long draft because of this large diameter of the rolls themselves. This objection is also, to some extent, present of the intermediate carrier rolls.
In the placing of the rolls close together for some attention must be given the weights at the back and front of the nip rolls with none of the parts extending between the points of nip of the rolls so that no such interference will result. I have also found that with certain traverse motions, that too bulky an arrangement of weights will traverse motion, and I have therefore made a very compact arrangement of weights in this present invention, so that the weighting means will have their centers in a common vertical I of these weights to faces 32 of the plane passing through the points of attachment the back and front rolls; and I have arranged the weights in some instances one within the other that this object may be more fully and completely carried out; and the following is a detailed description of the present embodiment of this invention illustrating the preferred means tageousresults may be accomplished. With reference to the drawings, Hi designates the breast beam of the machine on which there is supported two each shown here as supported by a standard H having a pedestal l2 resting on the breast beam. Each of these units supports a group of rolls comprising aligned front roils I3 and i4, back rolls l5 and I3 and intermediate rolls I1 and It, all rotatably supported in thecustomary manner, the'three line unit being shown, although this invention may be similarly applied to the four line roll system if desired. 1 V
The upper rolls i4of each unit are weighted by a common weight l9 generally rectangular in cross-section provided with a series of openings 20-at each of; its ends into which thelinks 2! may be hooked, the. latter being hinged to the curved links 22 which are hooked at their upper end to engage the reduced portions 23 between the working surfaces24a' of the rolls to apply weight thereto.
Openings or slots 24 are provided in the common'weight [9, in which openings there are suspended individual weights 25 for applying pressureto the top back roll l6 of each unit through the suspension member Ziiconnected to lever 2? which in turn is conne ted by link 28 to the lever 29, fulcrumed as at 30 and bearing upon the reduced portion 3| between the working sur- 7 back roll, and by this arrangement I may multiply the pressure applied to the back roll in any desired relation such as for instance as herein shown as four to one, by which arranged I may use a small weight and have a, correspondingly small opening in the weight !9 in which the same is suspended whereby the mass or bulk of the weight l9 may be main tained at a minimum. V g
In Fig. 4 I have illustrated the common weighting means for the front roll as consisting'of a in the usual manner.
weight 33 generally cylindrical in shape or circular in'cross-sectiomthe same being reduced as at 34 to provide a fin 35 with openings 36 therein for receiving the hook on the link 2i Instead of cutting out a portion of this weight 33 to receive a weight with in it as described above, I have provided an are shaped weight 31 which itself partially receives the common weight units for weighting the front rolls thereof.- In this manner the weights are kept compact and l the points of connection and pull and the center of'the nip rolls are all maintained in substantially thesame vertical plane. r
Fig. 6 illustrates the common weight 33 for both units which may be of any desired cross-section shape, and instead of providing a weight below the breast beam I0 I have mounted the weight 39 directly on the lever arm-2'! thuspositioning this weight 39 above the breast beam ill, this weight being adjustable along the arm and held in position by a suita le set screw 40.
In each of these constructions above described whichembody the lever 21 the same is pivoted about a fulcrum 4| consisting of an inverted Ll sl'ia ped member 42 adjustably mounted in the by which these advanba k to b k spinning units. substantial length being defined and 33 extending between the In some instances it is desirable to apply the back roll and to commonly weight the back rolls of two back to back units of a spinning frame. In Fig. 8 I have illustrated an are shaped weight 45 as hanging over and partly receiving the weight 33 as described in connection with Figs. 4 and 5 and extending a thereaio-ng, the same being provided with points of attachment 46 adjacent each end which are connected by links and 48 directly to the reduced portion of the back roll between the working surfaces thereof. The
weight directly to the openings 49 through the breast beam permit the I passage of these links and the unobstructed application of this pressure along the links to the back rolls.
By this arrangement I am enabled to connect the weights so that their center of mass or pull is in the plane with the point of connection of the weights to the rolls, thereby applying a pull or pressure upon the rolls in the desired ,direc- .tion without twist or distortion or requirement of balance. Also by this arrangement I provide a minimum number of parts which is important.
where disconnection is desired for removal of any of the rolls. The construction is such that the weights may act independently on the back and front rolls without interference with each other and yet close positioning of the rolls is permitted that long draft spinning may the weights are so arranged that the intermediate rolls may be lifted from position as desired without removing or disturbing any of the weights used, and the weights are housed one within the other that the minimum bulk or space is oocupied. I
Theforegoing description is directed solely towards the construction illustrated, but I desire it to be understood that I reserve the privilege of resorting to all the mechanical changes to which the device is susceptible; the invention limited only by the terms of the appended claims.
