Patented Jan. 24, 1933 PATENT OFFHIE FERNAND PIRON, OF WOONSOCKET, RHOIJE TSLAND YARN GUIDE FOR A SPINNING MACHINE Application filed August 4, 1931.
This invention relates to spinning machines and has for its object to provide means by which the short fibers of the yarn will become pressed into the yarn and thus avoid the loss of these fibers as lint or waste.
Another object of this invention is the provision of means by which less cleaning of the waste collecting rolls will be required.
Another object of the invention is to pro vide a more uniform thread, thus reducing the lumps and bunches and thin places formed.
A further object of the invention is to provide a heavier thread for a given length Which emanates from the spinning machine.
A still further object of this invention is the provision of a guide so arranged as to size and shape that it may be located between a the front roll and the next adjacent pair of carrier rolls and supported in this position without interferring with the removal of the rolls for cleaning.
With these and other objects in view, the invention consists of certain novel features of construction, as will be more fully described,
and particularly pointed out in the appended claims.
In the accompanying drawings:
Fig. 1 is a top plan view of a portion of the stationary part of a mule spinning machine, showing the rolls mounted therein, with parts of some of the rolls omitted to show the rolls therebeneath.
Fig. 2 is a sectional view through a set of rolls for operating upon the yarn.
Fig. 3 is a detailed face view of the guide whichi's the subject of this invention.
Fig. 4 is a sectional view on line 4t of Fig. 3. j.
Some type of spinning such as mule spinning used for the better grades of yarn comprises a movable carriage and a stationary part of the machine, with relation to which the carriage moves. In this stationary portion of the machine, there is mounted a plu- Serial No. 554,978.
rality of pairs of rolls traveling at different relative surface speeds between which the yarn extends prior to its being drawn out by the movable carriage.
The pairs of rolls so employed are posi- 5 tloned with their centers as close together as possible, consistent with practical operation, thus bringing their surfaces closely adjacent.
It is of course recognized that the smaller the diameter of the rolls, the closer together may be the points of contact of the two pairs of rolls. There is, however, a limit to the minimum diameter which can be had for the rolls, as these rolls must be sufliciently strong to withstand certain strains which are placed 69 upon them in use; such as the pull of the yarn, the weight on the rolls for nipping the yarn, and the driving of the rolls from one end of the machine, which may extend for a considerable length. The surface of the pairs of rolls must also have a sufficient clearance to permit any lint, which is gathered by the roll from the yarn, to pass between the rolls.
These features limiting thedistance be- 7 tween the nips of the pairs of rolls is particularly important with reference to the front pair and next immediate adjacent pair of rolls. Thus the space which is provided between these two pair of rolls is very limited but will not permit a support or the like extending between the pairs of rolls, but I have provided a guide which may be located within this minimum space and be supported from the over-arms between the marking surfaces of the roll and which arms sup port the bearings for the different rolls. The guide which I provide does not interfere with the removal of the rolls, for the piecing up of broken ends, should such broken ends occur, and the following is a detailed description of the present embodiment of this invention, illustrating the preferred means by which these advantageous results may be accomplished.
. tionary frame part of the mule spinning ma- 1 With reference to the drawings, the stachine isdesignated 10 from which there is support bearings 11 for the bottom back roll 12, bearings'13 for the bottom front roll 14, and bearings 15, 16 and 17 for the lower intermediate rolls 18, 19 and 20. An overarm 20 is supported from the standard 21 upon which there is mounted bearing 22 for the upper back roll 23. A bearing 24 for the upper front roll 25, andbearings 26, 27 and 28 which for the upper intermediate rolls 29, 30 and 31. These upper bearings arein the form of slots with open ends into which the axles or pins through the upper rolls may be guided and easily removed from the bearings when desired.
A weight is applied to the upper front roll by means of an arm 32, pivoting as at 33 and engaging a suitable axle 34 of the upper roll. A link 35 extends downwardly from this lever 32 to which there is a link 36 which has pressure applied thereto by the lever 37, pivoted at 38 and weighted at 39.
During the passage of yarn through this set of rolls, the same is flattened out to a con siderable extent, and fibers fray from the,
edges and are picked up by the rolls such as 14,20 and 25, and in order that this fray j or lint may .beremoved from theserolls,
These cleaner rolls are provided with a coverin of flannel to pick up the lint from a the wor ing rolls l4 and 25, and thus remove gagement with the lower roll 14 by the lever 45* alever arm 43 weighted as at 44, for the block 42, while the roll 40 is swung into en'- arm 45, provided with a weighted end 46.
In order to reduce the accumulated lint or.
fray of short fibers, whichaccumulate about the front pair of rolls,.I have provided a guide consisting of an elongated member or bar 47 provided with notches 48 or suitably spaced surfaces 49 and 50 through which the arn may extend and which is of a size to lie positioned in the small space'between the pairs of rolls 14, 25, 20 and 31, the. position being such that the bottom edge 51 of the guide is slightly above the tangential line between the last mentioned two pairs of rolls so as to assure that the yarn will contact with the bottom and both side surfaces thereof.
This rod 47 is supported at the point of reduction of the rolls for their bearings from the over arms 2O generally directly below and in the plane of the overarm by means of a yoke 52, similar to the guides or bearing such as at 27 or 28, in which case the rod- These cleaners are held in engagement 1. In a spinning machine, a
pairs of rolls between which the yarn travels, including a pair of front rolls and 9.
is independently adjustable from these bear ings, or the rod may be secured to one of these waste, to lie parallel with the longer fibers of the yarn as it passes the front rolls to force the short fibers backinto the yarn and thus reduces the accumulation of waste, and.
I have found that there is 80% less waste with the useofthis guide, whereby less cleaning of the rolls 40 and 41 is necessary and I have also found that where it hasbeen previously necessary to clean the rolls fifteen to twenty times a day, that with thisimprovement cleaning four or five times a day is sufiicient. In other words, the run may be many' hours longer without cleaning where this improvement is used.
Further, the maintaining of these fibersin the yarn provides a yarnof, more uniformdimension.
- The foregoing description is directed sole- 'ly towards the construction illustrated, but
I desire itto be understood that I reserve the privilege of resorting to all the mechanical changes to which the device is susceptible, the invention being defined and limited only by the'terms of the appended claims.
. I have described this invention more particularly as applied to a mule spinning-machinebut the invention may be used in other than a mule spinning machine, such as in the other types of spinning where therolls are similarly arranged. r Y TIclaimz; q
