Application filed November 27, 1326. Serial ll'o. 151.1%.
Yarn, in its passage through. a tension device, such, for instance, as a tension device con'iprising a movable tension member and its support, wears away more or less rapidly the yarn contact surface of the support, finally cutting a groove so deep to cause the movable tension member to become inoperative by removing its pressure on the yarn. This wearing away of the yarn contact sur face of the support is particularly rapid when certain yarns are used such as jute and asbestos; or when yarn is used which is dirty or 'ritty or which is filled with size. The tension support, because of this wear on its yarn contact surface, has had to be replaced frequently at a considerable expense.
The object of my invention is to provide a replaceable stationary member interposed between the movable tension member and its support for protecting the support from wear or to permit the further use of a support having a worn yarn contact surface, said replaceable stationary member being preferably made of a material which will resist the wearing efiect of the yarn to a much greater degree than the material of which the tension support can feasibly be made. My invention more particularly comprises a replaceable stationary plate inserted between a gravity operated rotatable tension Washer and the usual yarn contact surface of its support, said plate being provided with means such as a depending flange for preventing the yarn from being accidentally threaded under the plate.
Practical embodiments of my invention are represented in the accompanying drawings, in which Fig. 1 represents in top plan a yarn tension device with one form of replaceable plate applied thereto.
Fig. 2 represents a side view of the same.
Fig. 3 represents a detail section taken in the plane of the line IIIIII of Fig. 1.
Figs. l, 5 and 6 represent a second form of replaceable plate in top plan, side elevation and transverse section respectively.
Figs. 7, 8 and 9 represent a third form of replaceable plate in top plan, side elevation and transverse section respectively.
Figs. 10, 11 and 12 represent a fourth form of replaceable plate in top plan, side elevation and transverse section.
The yarn tension device in connection with which I have chosen to illustrate my inventlon is shown as comprising the tension head 1 which forms a support for a pair of gravity operated weighted tension washers 2 which are loosely mounted on pins 3 uprising from the usual yarn contact surface 4 of the support along which the yarn is drawn beneath the washers 2. The usual yarn guard 5 for preventing the washers from jumping off from their pins is pivoted to the support at 6. This supportl may be provided with the usual leading-in guide 7 and tension equalizing bar 8..
To eliminate the wear upon the usual yarn contact surface of the support 1 by thepassage of the yarn thereover between said surface and the rotatable washers, or to render further useful, supports having worn yarn contact surfaces, 1 provide a replaceable stationary plate 9, (preferably of hardened steel) which is inserted between the usual yarn contact surface of the support and the tension washers. In the forms herein shown, this plate is provided with holes 10 for receiving the uprising pins 3, to properly position the plate on the yarn contact surface of the support and hold it stationary.
Means are provided on the plates 9 for preventing the accidental threading of the yarn underneath the plates, which means in Figures 1, 2 and 3 is shown as a single depending flange 11 extending from the leading-in on d of he plate partway toward its rearbnd in close proximity to its adjacent side of the support. In Figures 4t, 5 and 6, I have shown a second depending flange 12 extending from the rear end of the plate partway toward its leadingin end. In Figures 7, 8 and 9 I have shown a single depending flange 13 extending the full length of the plate. In Figures 10, 11 and 12 I have shown the plate as being provided with a depending flange 14 opposite the depending flange 11 in close proximity to its adjacent side of the support. In this last form these two depending flanges may be shaped to snugly engage the opposite sides of the support to keep the plate in a more rigid relationship to the support.
From the above description it will be seen that 1 are enabled to readily provide a replaceable stationary member for coaction with the movable tension member, said replaceable member being preferably made of 'a greater wear resisting material than would.
be feasible for the support, because of the expense incident thereto. It will furthermore be seen that these plates may be very easily and readily replaced at a slight expense.
Furthermore, it will be seen that these platesmay put in use in connection with the numerous tension devices of this character now in operation, even Where the yarn contact surfaces of the supports have become Worn, thereby obviating the necessity of replacing the said supports.
It is evident that the several embodiments shown andi'lescribed are onl-ya few of many different forms which the tension might assume. It also evident that various changes inthe construction, form and arrangement of the several parts might be made ivithout departingfrom the spirit and scope oil my invention; hence, I do not intend to be lim-' ited to the particular embodiments herein shown and described, but What I=c1ain 1 s':- 1. In a yarn tens on device, a tension Washena stationary support therefor hav sugar and for permit Washer, a stationary support therefor having the usual yarn contact surfaceunder said Washer, and a replaceable noiryielding; stationary Wearing plate located upon said yarn contact surface for p 'otecting the same from me; t 'ie ur her u e of the tension device, said plate having a depending'flangc extendingrearwardly from its leading-in end 'in close proximity to the adjacent side of the support for preventing the accidental threading of the yarn underneath the plate. r
8. In a y-a-rn tension device, a, tension Washer, a stationary sup-port therefor having the usual yarn contact surface, and a replaceable non-yielding Wearing plate located upon said yarn contact surface for protecting the same from wear and for permitting the further use of the tension device, said plate having;- a depending flange extending rearwardly from its leadingsin end and en gaging its adjacent side of the support for preventing the accidental threading of the yarn underneath the plate, the nflate also having another depending flange-engaging the opposite side of the support to keep the plate in a more rigid relationship to the support.-
In testimony, that I claim the foregoing as my invention, I-have signed my name this 24th day of November, 19-26;
JOHN o. Meir-nan
