SUPPORT AND DRIVING MECHANISM FOR SPINNING-SPINDLES.

SPECIFICATION forming part of Letters Patent No. 589,995, dated September 1 4, 1897.

I Application filed August 1, 1890. Renewed October 6, 1893. Serial No. 487,389. (No model.)

dles and I do hereby declare the following to I be a sufficiently full, clear, and exact description thereof as to enable others skilled in the art to make and use the said invention.

This invention relates to spindles for spinning slivers of fibrous materials into yarns,

and has for its object the avoidance of friction in such spindles and the reduction of wear be- The nature of this invention to effect thesedeslderata consists in a bushing provided with l a shoulder and nut for holding the same in the rail of a spinning-machine frame, ad'just- 1 ing-screws to center the same into alinement with the other parts of the spinningmechanism, a shell or body fitted to screw into the bushing in central alinement and containing a hollow sleeve upon which the Whirl or pulley turns with devices for avoiding friction and within which the spindle is fitted concen trically, a lower bearing and lubricating-supply and waste-lubricant receptacle, and an equalizing or balancing carrier for transmiting rotary motion from the whirl to the spindle without imparting any lateral strain thereto.

The construction and operation of this invention are illustrated in the accompanying drawings, in which-- Figure 1 shows an elevation of the spindle containing this invention asapplied in the rail of a ring-spinning machine; Fig. 2, a central vertical sectionthereof; Fig. 3, a plan view; Fig. 4, a detached view of the bushing for holding the spindle-support in the frame,

1 represents a portion of the spindle-supporting rail of a spinning-frame; 2, the ring- -rail; 3, the ring; a, the traveler; 5, the coptube; 6, the spindle; 7, the lower bushing or hearing of the spindle; S,'the step under the bottom end of the spindle; 9, a bushing, preferably of hardened steel, in which the spindle rotates, and 10 a whirl or grooved pulley receiving motion from an endless cord or band The whirl 10 rotates around the upper part of the bushing 9 and, as shown in all of the figures of the drawings excepting only Fig. 11, is fitted with two or more series of spherical rollers 12, preferably of hardened steel, upon which it rolls around the bushing 9 with scarcely appreciable friction.

The bushing 9 is fitted into a bearing formed within and concentric with the axis of a tube 13, closed at the lower end, fitting exactly with a screw-thread 14c into a corresponding screw-thread in the interior of a bushing 15, and secured by a nut 16 in the bearingrail 1 of the spinning-frame.

The tube 13 is provided with a shoulder 17, which fits against the under surface of the bushing 15, the parts being so fitted or finished that the tube 13 isalways,whe1 1 screwed tightly into the bushing l5, coincidentin axis therewith. p

The bushings 15 are of sufficiently less diameter than the openings in the ring-rail in which they are placed as to permit of adjustment to line them concentrically with the rings 3 in the ring-rail 2.

In order to facilitate the centering of the rupting the working of contiguous spindles and without waiting for the ring-rail 2 to reach the upper end of its stroke.

Upon the upper side of the whirl 10 are formed two diametrically opposite projections 30,which engage in slots 31 in a plate 18, having two other slots 19 at right angles thereto, each of which engages one of two projections 20, diametrically opposite to each other, secured to the spindle 6 and transmitting the rotary motion from the whirl 10 through the projections 30, slotted plate 18, and projections 20 to the spindle 6.

The whirl 10 is supported upon the outer surface of the bushing f) and has no other connection with the spindle than through the slotted plate 18.

The slots in the plate 18 permit a sliding motion of the projections 30 and 20 in directions at right angles to each other, so that equal force is transmitted upon opposite sides of the spindle 6, and the spindle is thus protected from the effects of any concussions upon the whirl 10 from inequality of the driving-bands.

In the form shown in Fig. 12 a fork 32, fitting pivotally through the spindle with prongs 33 turned downward, engages in opposite radial slots 31 in the Whirl 10, and in the form shown in Fig. 13 a tube 35, connected pivotally by gimbal- rings 36 and 37 to the spindle and whirl,respectively,transinits rotative motion from the whirl to the spindle without transmitting any vibratory motion between the parts. The balls 12 roll between the inner surfaces of the whirl 10 and the outer surfaces of the bushing 9, so that a minimum of friction is preserved. The balls 12 are kept in their proper planes of rotation by a collar 22 and shoulder 21, formed in the whirl 10, and a like shoulder upon the bushing 9. (See Fig. In this form the weight of the whirl and the downward pressure resulting from the strain of the driving-band 23 are sustained by the balls 12 between the shoulder 21 and the shoulder of the said bushing, avoiding the friction otherwise incident to surfaces mov ing in sliding contact with each other.

As shown in Figs. 12 and 13, there are several series of balls interposed between the bushing 0 and whirl 10. It should be observed that the lower series of balls 12, which support the weight of the whirl 10 and the downward thrust or draft of the drivingband 23, do not touch the cylindric surface of the bushing, but are free to roll with the velocity acquired from the shoulder 21 on the whirl 10.

In Fig. 11 of the drawings is shown a form of this invention, in which the whirl 10 is fitted directly upon the bushing 9, and consequently requires lubrication more frequently. 0n the lower part of the whirl 10 there is formed a rim 21, having its greatest external diameter at the lower edge. The function of the rim 24: is to convey any surplus oil from the whirl 10 downwardly within a surrounding rim 25, formed on the upper end of the tube 13, in which rim 25 such oil is whirled from the rim 21 and collected, whence it is conducted downwardly, as hereinafter described, and utilized in lubricating the lower wearing parts. The tube 13 is bored out accurately in line with the axis of the screwed portion and exactly true with the shoulder 17, so that the bushing, 9 and bearing 7 and step 8 are always accurately in line. Chambers 26 are formed between the bearings of the bushings 9 and bearing '7 and step 8, and channels 31 are cut lengthwise through these bearings to permit oil to flow down from the top to lubricate them and to flow below the step 8 and deposit any sediment or heavier foreign substances in the oil below the bearin g-surfaces, thus protecting the wearing parts from injury and affording a space for the subsidence of the oil after its lubricating properties are exhausted or impaired. A spring-plate 28, attached by screws 38 (shown in Fig. 3) to the bushing 15, projects over the whirl 10 and serves to prevent the whirl 10 and spindle 6 being accidentally lifted from the bearing,and by being pressed downwardly at the free end into contact with the whirl 10 serves as a brake to arrest its rotation.

To remove any of the spindles and bearings, it is merely requisite to unscrew them from the bushing 15 and withdraw them downwardly, which can be done with the ring-bearing rail in any position and without the least interference with the work of contiguous spindles. A cap 27 serves to cover and protect the carrier and whirl from dust.

I am aware that spinning-spindles have been made elastically connected with driving-whirls, and that spinning-spindles connected by frictional surfaces with their driving-whirls have been used also, that spinning-spindles supported to gyrate upon axes other than that of their geometric form have been connected with their driving-whirls by a cross-pin passing through the spindle loosely and secured in the whirl, none of which devices do I claim; but,

Having described my invention, what I claim is 1. In a spinning-spindle supporting and driving mechanism a stationary bushing or bearing sleeve, the spindle having a journal bearing in said bushing or hearing sleeve, a whirl concentric with said spindle and supported upon said bushing or bearing sleeve independently of the spindle, in combination with a rotative driving mechanism, consisting of a pair of projections attached to the spindle, a pair of projections attached to the whirl, and the connecting-plate 18 engaged on said projections for transmitting rotary motion and permitting motion of each pair of projections in a direction at right angles to the motion of the other pair of projections substantially as set forth.
