H. TER MORS SPINNING 0R Tws'rING SPINDLE Filed Nov. 5, 1958 mwN-roe HEN NB TER MORS Patented Oct. 31, 1939 UNITED STATES PATENT OFFICE SPINNING R TWISTING'SPINDLE Netherlands Application November 5, 1938, Serial No. 239,117 In the Netherlands November 9, 1937 4 Claims.

In spinning spindles it has already been attempted to avoid the well known ballooning. To this end it has been proposed to wind the yarn around the spindle by using a row of teeth arranged on the spindle tip. The thread guide is arranged immediately above said row of teeth in such a manner, that the yarn is bent twice angularly. Although ballooning may thereby be avoided the yarn is strongly loaded and the risk o of breakage of thread is rather considerable.

It has been attempted to remove this drawback by arranging the means for revolving the yarn not on the tip of the spinning spindle but at the top of the circumference of the spindle. The

5 yarn is suffering less thereby but another drawback isl then encountered; one has not succeeded in applying this construction to the socalled weft-spindles, i. e. thin spinning spindles and weft tubes telescoped into each other.

0 The invention has for its purpose to remove the drawbacks of the one construction as well as of the other and starts from a spinning or twisting spindle provided with anti-ballooning means locally projecting outside the imaginary exten- 5 sion of the upper end-portion of the spindle.

According to the invention in order to avoid ballooning the means for revolving the yarn arriving on the spinning or twisting spindle consist of a ring the plane of which occupies an upstanding position upon the spindle tip, the lower portion of which ring may be embedded in the upper tip surface.

In a spindle of this kind the tipA offers less air resistance and further less eddy air currents are 5 produced. The yarn is less loaded and the risk of breakage is reduced. The novel construction may be manufactured in a simple and sturdy manner.

The term ring besides including circular members also includes otherwise shaped equivalent elements the main shape of which is a circle, ellipse or similar regular gure. Y

The invention may be applied to warp spindles as well as to weft spindles by reason of the fact i that the tube may be readily passed over the annular yarn revolving member located above the spindle proper and allows for the extremely small deformation required at the upper end.

Theinventionl will be more fully understood i with reference' to the accompanying drawing illustrating two embodiments thereof.

Fig. l is a front elevation of a weft spindle according to the invention.

Fig. 2 is a corresponding side elevation of the i upper portion.

Figs. 3 and 4 are corresponding views of a warp spindle, the tip. in Fig. 4 being shown partially in section.

In Figs. l and 2, l is a weft spindle having a diameter at the top end of only 4 millimeters, on 5 the upper surface 2 of which a ring 3 has been soldered with the aid of copper. This ring projects laterally outside the extension of the upper portion of the spindle, so that the ring catches and carries along the arriving yarn supplied l0 centrally to the spindle and at some distance thereabove via a thread guide. Notwithstanding this the narrow upper end of a weft tube may be passed over the ring, while being temporarily slightly deformed. 18

'Ihe principle described may also be applied to warp spindles as shown in Figures 3 and 4 by way of example. On the spindle 4 a head 5 is screwed the circumferential surface of which is lying in one plane with that of the upper spindle 20 end and constitutes a continuation thereof. To the upper surface 2 of the head a ring 3 is soldered which is partially embedded into said upper surface. By using copper solder or otherwise the connection of the ring or the like with the g5 spindle proper may be such that there is no danger for the yarn to be caught. Also in the construction shown in Figs. 3 and 4 a weft tube may be readily passed over the spindle.

Since the annular yarn revolving means is not arranged at the upper end of the circumferential surface of the spindle the weft tubes, even from weft spinning spindles, may be easily removed.

The invention is not restricted to the practical embodiments illustrated but also includes all spinning or twisting spindles comprising on the tip surface an annular yarn revolving means locally projecting outside the imaginary extended circumferential surface of the upper spindle portion.

I claim:

1. A spinning or twisting spindle provided with yarn revolving means to avoid ballooning, comprising a ring arranged in upstanding position on the top of the spindle and locally projecting outside the imaginary extension of the upper spindle portion.

2. A spinning or twisting spindle provided with yarn revolving means to avoid ballooning, comprising a ring mounted inupstanding position on the top of the spindle with the lower portion of said ring embedded in the upper surface of the spindle tip, the side edges of said ring projecting laterally outside the imaginary extension of the upper spindle portion above the actual top end of the spindle.

3. A spinning or twisting weft spindle provided with yarn revolving means to avoid ballooning, comprising a ring soldered in upstanding position on the top of the spindle and projecting laterally outside the imaginary extension of the upper portion of the spindle.

4. A spinning or twisting warp spindle prom vided with yarn revolving means to avoid ballooning, comprising a ring soldered in upstandinz position on a head, said head being screwed'onto the top of the spindle and having a circumferential surface forming a continuation ot the spindle, the side edges of said ring projecting laterally outside the imaginary extension o! said cylindrical surface above the actual termination of said head.
