7 TENSION DEVICE FOR WINDING MACHINES Filed July 20, 1928 2 Sheets-Sheet 2 INYENTOR ATTORNEY Patented Mar. 25, 1930 PATENT OFFICE DAVID PALIN, or PAWTUCKET, nnonn snnnn TENSION DEVICE FOR WINDING MACHINES Application filed July 20,

Thisinvention relates to a tension device for winding machines, the general object of the invention being to provide means for controlling thetension of the thread or yarn as it is drawn off of a yarn carrier on to a receiver so as to wind the yarn evenly upon the spool and to free it of kinks and to make the device so that it can be adjusted for different grades of yarn.

Another object of the invention is to provide a plurality of wedge-shaped weights, with holding means for the same so that a weight of any desired size may be used with the device according to the kind of yarn being spooled.

This invention also consists in certain other features of construction and in the combina tion and arrangement of the several parts, to

be hereiaft r fully describe'd,"illustrated in the accomp nying drawings and specifically pointed out in the appended claims.

In describing the invention in detail, reference will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which Figure 1 is an elevation of the device.

Figure 2 is a front view thereof.

Figure 3, is a plan view.

Figure 4 is a section on line. 4-4.- of Figure 3.

Figure 5 is a section on line 5-5 of Figure 4.

Figures 6, 7 and 8 are perspective views of the weights.

, Figure :9 is a section on line 9- 9 of Figure 1.

In these views, the numeral 1 indicates an upright which is formed with a forked lower end to engage the transverse bar 2 of the machine on which the device is used, a bolt 3 acting to clamp the upright to the bar. This upright is formed with a slot 4 having notches 5 in one of its vertical walls and with a ver- 4 tical row of holes 6.

The spindle 7 for the bobbin 8 is carried by a substantially L-shaped bracket 9, the long arm of which is formed with a slotted angular extension 10, through the slot of which abolt 11 passes, this bolt being adapted to engage passes after it leaves the guide 15. 1 A similar- 1928. Serial No. 294,166.

.any one of the notches 5 whereby the bracket can be adjusted vertically on the upright. A teat 12 is carried by the extension 10 and is adapted to engagev any one of the holes 6 in the upright. A looped guide carrier 13 is adjustably connected with theupper part of the upright by the bolt 14 which passes through the looped part of the carrier and a guide 15, preferably formed of porcelain, has a threaded part passing through the eye of the long arm of the carrier, with a nut 16 on the bolt for clamping the guide to the carrier.

A forked plate 17 is fastened to the inclined upper end 18 of the upright by the bolt 19 and the wing nut 20 so that this plate can be removed when desired. A' depending plate 21 is fastened to one prong of theforked plate 17 by having its upper end bent to engage the prong and a bolt 22 passes through a Washer plate 23, a slot in the bent upper end of the plate 21 and through the prong. The lower end of the plate 21 is provided with a slot 24 through which the thread or yarn 1y shaped plate 25 'is adjustably connected with the other prong of the plate 17 by the bolt 26 which passes through a slot 27 in the prong and through the bent end of the plate 25. s will be seen, the plate 21 is adjustable toward and away from the plate 25, while the plate 25 is adjustable at right angles to the plate 21. The plate 25 is also much shorter than the plate 21. The

plates

21 and 25 are convergently arranged, with a space between their lower portions and as will be seen from Figure 4, the two plates form a V-shaped recess. A channel member 28 iscarried by the plate-25, the flanges of the member tapering downwardly with the tapered part of the member extending into the V-shaped recess as shown.

Any one of a number of wedge-shaped Weights, such as shown at 29, 29 and 29" in Figures 6, 7 and 8, is adapted to be placed in the channel member with its operative face resting against the plate 21 and thus engaging the thread and acting to-place the same under tension. After leaving the weight, the 100 thread passes over a stationary roll 30 held in the limbs of a U-shaped member 31 which is adjustably connected with the plate 17 by the bolts 32 passing through slots 33 formed in the bight of the member 31. A long bolt '34 passes through the roll 30 and through tightening the nut, the arm will be held in ad justed position.

From the foregoing it will be seen that the 2. A tension device for a winding machine comprising a support, a pair of convergent members carried by the support and forming a V-shaped recess, the lower end of which is open and one of the members having a notch in its lower end whereby a thread can passthrough the notch and through the recess and a wedge-shaped weight in the recess and pressing the thread against one of the convergent members;

In testimony whereof DAVID PALIN.

bracket 9 can be adjusted vertically to place the bobbin any desired distance from the guide 15 and that the weight holding member 28, as well as the roll 30, can also be adjusted to suit the conditions under which the device is working. The thread can be guided by one hand through the Me 15, the slot 24; and through the space 'etween the

members

21 and 28, the weight carried by the member 28 holding the thread in position. Then the thread is carried over the roll 30 under the arm 36 to the spool.

By adjusting the arm 36 in relation to the roll 30, the tension'exerted on the thread or yarn can be controlled and if this tension is not suficient, a heavier weight can be placed in the member 28 so that by using the proper size weight and adjusting the'arm 36, the

proper tension can be placed on the thread or yarn to remove kinks and to form a hard spool with the thread evenly wound thereon.

As will be seen, this device is extremely simple and can be easily assembled and the parts can be easily and quickly adjusted according to the kind of yarn being used and any part can be replaced when worn or broken. By removing the forlred plate 17, the

parts carried thereby can be used on other kinds of winding machines.

lt'is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combina tion and arrangement of the several parts, provided that such changes fall within the scope of the appended claims,

W hat I claim is:

l. A tension device for a winding machine comprising an upright, means for attaching it to a part of the machine, a plate attached to the upper end of the upright, a pair of depending convergent members carried by the plate, one of which has a slot therein, holding I means on the other member, and a wedge-- shaped weight removably held by the holdmg means and engaging one face of the slotted convergent member,
