JOHN D. MGKEAN, 0F WES'IFIELD, MASSACHUSETTS, ASSIGNOE T0 MACHINE 7 COMPANY, OF WES'EFIELD, TEASSACHUSETTS, A CORPOBATIGN OF MASSACHUSETTS.
TENSION DEVICE.
Application filedFebruary 4, 1922. Serial No. 534,145.
To (/JZ 107M772, it may concern Be it known that I, Join O. Molina a citizen or" the United States, and resident of Westiield, in the county of Ha-mpden and State of Massachusetts, have invented a new and useiiul Improvement in Tension Devices, of which the "following is a specification.
In drawing yarn from the bobbin over the head there is a tendency for the yarn to kink as it leaves the bobbin. This: is especially true where the yarn has a particularly hard wind or twist. p
The object oi? my invention is to provide a tension device which will coa'ct with the bobbin to prevent the kinking of: the yarn as it is drawn from. the bobbin over the head of the bobbin.
The object of my invention more particularly is toprovide a gravity operated tension device which will press against the bobbin head, between which tension device and the bobbin, the yarn will be caused to pass as it is drawn from the bobbin, it being understood that the bobbin is held stationary.
A practical embodiment oi my invention is represented in the accompanying drawings, in which- Fig. 1 represents so much of a winding machine as will illustrate my invention.
Fig. 2 reprggents a section taken in the plane of the line IIII of Fig. 1.
Fig 3 represents an end view of one of the bobbins and tension device whch coacts therewith.
The bobbin holder comprises a bracket, two arms 1 and 2 of which embrace a bar 3 of the machine. A set screw 4- may be used for adjustably securing the bracket to the said bar 8. This bracket is provided with a third arm 5 from which project two substantially parallel pins 6 and 7. In the present instance these pins project diagonah ly upward from the bracket and the stationary bobbin 8 is mounted against rotation on the pin 7.
The tension device which I have shown herein comprises a sleeve 9 which is adjustable along the pin 6 and also rot-atively adjustable thereon so as to enable it to be fixed in any desired longitudinal and rotative adjustment with respect to the bobbin. A set screw 10 may be provided for clamping the sleeve 9 in its adjusted position. This sleeve 9 is provided with two cars 11 and 12 arranged to receive the free ends of a gravity operated U-shaped element 13, whereby the element is pivoted to the sleeve. Tlhis element may be removed from the sleeve by springing its tree ends out of their pivotal engagement with the ears 11- and 1:2.
' This gravity operated element 13 presses lightly against the bobbin head and the yarn as it is drawn from the bobbin over the head is caused to pass between this gravity operated element and the bobbin, thus not not only preventing the tendency of the yarn to kink at this point, but also serving to exert a slight tension. on the yarn.
The pin 6 may be developed into a yarn guide 1% beyond the bobbin head.
It is evident that various changes in the construction, form and arrangement oi the several parts may be made without, departingfrom the spirit and scope of my invention; hence do not wish to limit myself to the particular embodiment herein represented, but,
What I claimis 1. A bobbin holder, and a gravity operated tension device arranged to coact with the bobbin to prevent the kinking of the yarn as it is drawn from the bobbin over the head of the bobbin.
2. A bobbin holder, and a gravity operated tension device arranged to press against the bobbin head, between which ten sion device and bobbin head the yarn passes as it is drawn from the bobbin over the head of the bobbin, to prevent the kinking of the 3. A bobbin holder, a gravity operated tension device arranged to coact with the bobbin to prevent the kinking of the yarn as it is drawn from the bobbin over the head of the bobbin, and a support for the tension device, carried by the bobbin holder.
4. A bobbin holder, a gravity operated tension device arranged to press against the bobbin head, between which tension device and bobbin head the yarn passes as it is drawn from the bobbin over the head of the bobbin, to prevent the kinking of the yarn, and a support for the tension device, carried by the bobbin holder.
5. A bobbin holder comprising a bracket, 3. pin projecting therefrom, a second pin projecting from the bracket alongside of the bobbin, and a tension device carried by the second pin and arranged to coact with the bobbin head to prevent the kinking of the yarn as it is drawn fromthe bobbin over the head of the bobbin.
6. A bobbin holder comprising a bracket,
a pin projecting therefrom, a second pin projecting from the bracket alongside of the first named pin, and a'gravity operated tension device carried by the second pin and arranged to coact With the bobbin head to which tension device and bobbin. head the yarn passes as itis drawn from the bobbin over the head of the bobbin, to prevent the kinking of the yarn.
8. A bobbin holder comprising a bracket, a pin projecting therefrom, a secondpin projecting. from the. bracket alongside of the first named pin, and a gravity operated tension device carried by the second pin and arrangedto press against the bobbin head, between which tension device and bobbin head the yarn passes as it is drawn from the bobbin over the head of the. bobbin, to. prevent the kinking of the yarn.
9. A bobbin holder, and a tension device having a gravity operated. removable. element. arranged to coact with the bobbin to prevent the kinking} of the yarn as it is drawn from the bobbin over the head of the bobbin.
10. A bobbin holder, and a tension device having a gravity operated removable element arranged to press against the bobbin head, between Which element and bobbin head, to prevent the kinking of the yarn as it is drawn from the bobbin over the head of the bobbin.
12. A bobbin holder comprising a bracket,
a pin projecting therefrom, a second pin a developed into a yarn guide, and a tension device carried by the second pin comprising a sleeve adjustable along the pin, and.
a gravity operated removable element arranged to coact with the bobbin head, to prevent the kinking of the yarn as it is drawn from the bobbin over the head of the bobbin. I
In testimony, that I claim the foregoing as my invention, I have signed my name Feb, 1922.
