UNITED STATES PATENT OFFICE.
EMYGDIO SOARES MEDEEROS, OF NEW" BEDFORD, MASSACHUSETTS, ASSIGNOR OF ONE- HALF TO JOSE PACHECG C(JRREIA, OF NETN BEDFOBD, MASSACHUSETTS.
TENSION DEVICE FOR SPOGLING MACHINES.
Application filed April 30, 1925.
T 0 all whom it may concern:
Be it known that I, Errvenro SoAnns Mn- DEIROS, a citizen of the United States, residing at New Bedford, in the county of Bristol and State of Massachusetts, have invented a new and useful Improvement inTension Devices for Spooling li lachines, of which the following is a specification.
My invention has reference to an improvement in spooling machines and more particularly to an improvement in thread tension devices, such as shown in United States Patent No. 1,450,559, thread tension device, granted to me April 3, 1923.
In the usual. construction of spoolers, the thread tension devices, such as shown in my United States patent referred to form a fixed part of the spooler when in use and such spoolers have a bar with thread guide plates which have thread slots through which the threads go, from the bobbins through the tension device to the spools. The thread guide bar and plates of the spooler have a vertical movement and in this predetermined up and down movement of the thread guide bar it brings the threads at varying angles under the thread guides of the tension devices and this varying positioning of the threads causes an uneven tension on the threads.
The object of my invention is to provide the bar of the thread guide plates of spoolers with thread tension devices, whereby uneven tension on the threads as the threads come from the thread tension devices, to the spools, is eliminated.
A further object of my invention is to improve the construction of such a thread tension device, whereby the thread tension device is easily, quickly and rigidly secured to the thread guide plate bar of a spooler, the thread tension device is improved as a whole and a more perfect and uniform tension on the thread is obtained than has heretofore been done.
My invention consists in the peculiar and novel construction of a thread tension device for spooling machines and in the positioning of t e thread tension device on the thread guide plate bar of a spooling machine, said thread tension device having de tails of construction, as will be more fully set forth hereinafter and claimed.
Figure 1 is a side view of my improved thread tension device for spoolers, and
Serial No. 26,984.
showing part of a spooler with the spindle support rail and the bar of the spooler thread guide plates, in section.
Figure 2 is a front view of my improved thread tension device.
Figure 3 is a top plan view of the thread tension device.
Figure 4 is a detail vertical sectional View taken on line 4, 4 of Figure 3.
Figure 5 is a detail vertical sectional view taken on line 5, 5 of Figure 3, and
Figure 6 is a detail vertical sectional view taken on line 6, 6 of Figure 3.
Figures 2, 3, 4, 5 and 6 are enlarged to more clearly show my invention.
In the drawing 1 indicates a fixed spindle support rail in section, 2 a movable thread guide plate bar in section, 3 a bobbin spindle support of a spooler, 4 a bobbin, 5 a thread and 6 my improved thread tension device for spooling machines.
The spindle support ail 1, shown in section in Figure 1, forms a rigid part of the spooler and to it is secured the spindle sup port 3 having the usual spindle, shown in dotted lines in Figure 1. The bobbin 4 on which is wound the thread 5 is supported on the spindle of the spindle support 3 in the usual way. The thread guide bar 2, shown in section in Figure 1, carries the usual thread guide plates with slots for the threads, not shown and this bar 2 has a predetermined vertical movement when the spooler is in operation, as shown in Figure 1 the tension device 6 is in one of the posi tions assumed by the bar 2.
My improved thread tension device 6 for spooling machines consists of a flat plate 7 having a bifurcated end 8 forming a thread entrance slot 9 which terminates in a hole 10 in which is a porcelain thread guide eye 11, also having a thread entrance slot 12 coinciding with the thread entrance slot 9. The other end of the plate 7 is formed into an inverted U-shaped end 13 shaped to go over the thread guide plate bar 2 and having a bolt 14 screw-threaded through the end 13 and bearing on the bar 2. By tight ening the bolt 14, the tension device 6 is "1 ly secured to the bar 2. Located centrally on the plate 7 and somewhat off a central line is a round vertical metal stud 15 having a reduced stem 10 forming an annular shoulder 17. The stem 16 extends downwards through a hole 18 in the plate 7 and is screw-threaded on its lower end for a nut 19. Intermediate the bottom of the plate 7 and the nut 19 is a soft rubber washer 20. On the plate 7 is a porcelain thread tension washer 21 having a central hole 22 for the stem 16 and aneck 23 which abuts against the shoulder 17 of the stud 15 and on top of the thread tension washer 2-1 is a loose porcelain thread tension washer 2a having a central hole 25 for the stud 15, as shown in Figure 4. On the tension side of the plate 7 is secured a horizontal pin 26 to which is secured a lateral porcelain thread guide 27 having inwardly bent hook shaped ends 28, 28, as shown in Figures 2 and 3. Secured to the plate 7 is a wire guard 29 having vertical stems 30, 30 the lower ends of which are secured to the plate 7. hese vertical stems 30, 30 merge into L-shaped horizontal members 31, 31 having a loop shaped end 32, as shown in Figures 1, 2 and 3.
The operation of my improved thread tension device for spooling machines is as follows. The tension device is rigidly secured, as described, to the movable thread guide plate bar 2 which has a predetermined up and down movement in the spooling machine, to guide the threads on the spools. The thread..5 comes from the bobbin l upwards through the porcelain thread guide eye 11 then over and between the porcelain thread tension. washers 21 and 24 and partly around the neck 23, then down and under the lateral porcelain thread guide 27 and then upward and through a thread slot in a plate, not shown, on the thread guide plate bar 2 to a spool on which it is wound.
By this construction and positioning of my improved thread tension device in a spooling machine, the tension on the thread is always uniform, as the angle of the thread, as it comes from under the lateral thread guide 27 does not vary and is always at the same angle. With a thread tension device in a fixed position, as heretofore, the up and down movement of the thread guide plate bar of the spooler will cause the thread to assume innumerable angles and this causes the lateral thread guide 27 or its equivalent, from under which the thread comes, to vary the friction or tension on the thread.
I do not Wish to confine myself to the construction shown as the construction could be modified within the scope of the appended claims.
Having thus described my invention I claim as new 1. In a spooling machine, a thread tension device comprising a plate having a bifurcated end forming a thread slot. a porcelain thread guide eye at the end of the thread slot and having a corresponding thread slot, a lower porcelain thread tension washer on the plate and having a neck and a central hole, a stud having a shoulder bearing on the neck of the tension washer and a screw-threaded stem which extends through the tension washer and through a hole in the plate, a rubber washer and a nut on the screw-threaded stem and an upper porcelain tension washer on the lower tension washer and means for securing the thread tension device to the movable thread guide device of a spooling machine, for the purpose as described.
2. A movable thread tension device for spooling machines comprising a plate having a bifurcated end forming a thread slot, a porcelain thread guide eye at the end of the thread slot and having a corresponding thread slot, a lower porcelain. thread tension washer on the plate and having a neck and a central stud hole, a stud having a shoulder bearing on the neck of the tension washer and a screw-threaded stem which extends through the tension washer and a hole in the plate, a rubber washer and a nut on the stem, an upper porcelain tension washer on the lower tension washer, a lateralpin secured to the edge of the plate, a. porcelain thread guide secured to the lateral pin and means for securing the plate to the movable thread guide device of a spooling machine, for the purpose as described.
