MACHINE FOR TWISTING AND SPINNING FIBROUS MATERIALS.

SPECIFICATION formingpart of Letters Patent No. 699,203, dated May 6, 1902.

Application filed May 6,1901. Serial No. 58,867. (No model.)

To LZZ whom it may concern..-

Be it known that I, JOHN MARSHALL, a citizen of the United States, residing at Pawtucket, in the county of Providence, State of Rhode Island, have invented a certain new and useful Improvement in Machines for Twisting and Spinning Fibrous Materials, of which the following is a specification, reference being had therein to the accompanying 1o drawings.'

The invention has relation to twisting` and spinning frames ofthe class in which rotating rings are employed in lieu of 'the' fliers formerly used.

The invention consists in a novel means of supporting a rotating ringin machines'such as referred to and in the means of effecting lubrication.

The invention involves the use in connec- 2o tion with a rotating ring of antifrction-rolls or the like for the purposes of aifording lateral support to the ring, and preferablyvertical support as well, and in addition restraining the ring from rising out of place.

In the drawings, Figure 1 shows in vertical transverse section on the plane indicatedby the dotted line 1 1, Fig. 3,aring-rail having applied thereto a rotating ring of the character hereinbefore mentioned and illustrates one in vertical transverse section on the plane indicated by the dotted line 2 2in 3 shows in plan a portion ofthe length of the said rail and some of the parts which are applied thereto in practice. 'Fig 4 showsv in plan a pair of the antifriction rolls or Wheels and their carrying-plate removed from the rail. views showing modifications.

4o Having reference to the drawings, the ring# rail is designatedl', and therotating ring is designated2. contemplated'that` the ring 2 shall be driven by meansv of a band applied to the same, and the groove for the reception of the said band is designated 21. i

In Figs. 1 to 3 I have illustratedan em-` bodiment of the invention in Which ring 2 embodiment of the invention. Y Fig. 2 is a viewV Fig.

Figs. 5 to 9 are partly-sectional detail;

In the present instance it isantifriction rolls or wheels 3 3, dto., mounted in connection with the ring-rail and arranged symmetrically around the ring 2. These rolls or wheels constitute lateral bearings which sustain the ring against tendency to movement transversely. The rolls or wheels are shown mounted on vertical axes. Herein the rolls or wheels revolve upon pins 3 3, carried by plates 3b 3", resting on lugs 1a l, that `are cast or otherwise provided on the rail 1, the said plates being secured in place by meanslof screws 3 3C, passing through transverse slots 3d 3d in the said plates into tapped holesfinthe said lugs l la. Suitable heads or collars 3e 3e, on the lower ends of the pins 3a 3 aord vvertical support to the rolls or Wheels 3 3. In this embodiment of the invention the peripheries of the rolls or Wheels 3 3 are formed with V-shaped grooves receiving a projecting V-shaped rib 2b, with which the ring 2 is formed or provided. By the entrance of the V-shaped rib into the V-shaped grooves the ring 2 is supported vertically and at ,the same 4time is held from rising. Obviously the construction j ust, described may by reversed by forming the ring with a V- shaped groove and forming the rolls or wheels 2 2 with V-s haped peripheries to enter the groove in the ring. A rotatable ringmounted and supported in the manner which I have just described is capable of working at exceedingly high ve-y locities and with very slight friction and wear. The matter of properly lubricating the bearing-surfaces is ofexceedingly great importance in connection with spinning appliances, and especially when Working at the exceed-V ingly high velocities calledwfor in modern practice. With my inventionthe need for lubrication is lessened, while at the same time the matter of providing properly vfor eecting lubrication is facilitated and less injury will be experienced in case the supply of lubri-V cant should run low.

-By Way of enabling the lubrication of the contacting surfaces of the moving parts to be effected conveniently and readily Without Aloss of time or waste of lubricant I chamber the ring-rail, as shown in Figs. 1, 2, and 3,

and I arrange the antifriction rolls or wheels within the cavity or chamber` of the rail. The lubricant is simply poured intothe cavity or chamber. The lower ends of the pins 3 3L and portions of theantifriction rolls or wheels extend downward into the chamber or cavity of the rail to near .the bottom of the said chamber or cavity, and consequently become more or less immersed in the lubricant,which thereby is enabled to work in between the bearing-surfaces of the said rolls or wheels and the pins and also is carried by the rotation of the rolls or wheels to the portion of the ring which engages with the latter. Thereby all relatively moving surfaces are lubricated. In this construction the V-Shaped rib 2b is formed on a skirt projecting downwardly below the band-groove of the ring, the said skirt and V-shaped rib also extending below the plates 3", on which the antifriction rolls or wheels are mounted. The ring is arranged concentrically with relation to a sleeve 4, rising from the bottom of the chamber or cavity of the ring-rail. The spindle in connection with which the ring is employed passes upward in practice through the opening of this sleeve. For the purpose of more effectually providing against access of the lubricant to the spindle and to the bobbin or cop-tube and yarn-load thereon I continue the said sleeve 4 upward above the general level of the top of the ring-rail, as shown most clearly in Fig. 1, and I chamber the ring interiorly, as at 2C, to receive the upper portion of the sleeve. It is not intended that the sleeve and ring shall make lateral contact with each other. The chambering of the ring is advantageous in that it reduces the weight of the same.

5 are cover-plates which are applied to the top of the ring-rail above the plates 3* 3".

The inwardly-projecting portions of the plates 3b 3b are beveled off, as at 3f 3f, Fig. 1, in order that lubricant flashing off the antifriction-rolls or the rib 2" of the ring and striking against the ends of such portions may be deiected-downwardinstead of beingcaused to spatter upward against the cover-plates 5 5, the upper portion of the ring, or the drivingband.

For the purpose of enabling any required adjustment of the antifriction rolls or wheels relatively to the ring to be made-as, for example, for the purpose of causing the said rolls or wheels to tit properly against the ring as well as for the purpose of enabling the ring to be adjusted transversely into concentricity with the spindle-the plates 3b 3b are slotted, as described at 3d 3, where the screws 3c 3c pass through the same into the lugs l 1L of the ring-rail. For convenience in enabling the required adjustment to be made I provide, in connection with the said plates 3* 3, adjusting devices, here shown as constituted by set-screws 3lg 3,passinginwardly through tapped holes in the side walls of the ring-rail and making contact at their inner ends with the outer edges of the plates 3" 3", the said set-screws being provided with lock-nuts 3 3.

I provide the antifriction rolls or wheels 3 3 with elongated bearing portions 3- 3j, fitting the pins 3. 3", in order to distribute the wear, prevent unequal cutting or wearing of the said pins, and secure increased steadiness of the said rolls or wheels and the ring 2.

Various changes may be made in the form and arrangement of the antifrictiou rolls or wheels 3 3 andthe coperating portion of the ring, as well as in the relations of these parts, without involving a departure from the principles of the invention. Thus the peripheries of the rolls may be formed as short cylinders, as at 3k in Fig. 5, entering right-angled grooves in the skirt of th'e ring, or the peripheries may be beveled, as at 3, Fig. 6, entering a corresponding inclined or beveled groove in the skirt of the ring. Where the antifriction rolls or wheels are desired to hold the ring from upward movement without supporting the same vertically, the said rolls or wheels and ring may be shaped and combined as in Figs. 7 and 8. Where the rolls or wheels are required to support the ring vertically without acting to prevent the same from rising, the parts may be shaped and combined as in Fig. 9.

The number of rolls or wheels employed in connection with each ring may be'varied in practice.

The ring is provided in practice with a suitable guide 9, through which the roving or yarn passes on its way to the spindle, bobbin, or other receiver.
