IMPROVEMENT IN SPINDLE-LUBRICATORS FOR SPINNING-MACHINES.

Specification forming part of Letters Patent No. 42,569, dated May 3, 1864.

T 0 all whom it may concern.'

Be it known that I, JAMEs EATON, of Boston, in the county of Suffolk and State of Mas` sachusetts, have invented an Improvement in SpindleLnbricators and I do hereby declare that the following is a full and exact description of the construction and use of the same, reference being had to the accompanying drawings, andto theletters and figures marked thereon.

Similar letters of reference indicate corresponding parts iny all of the figures.

Figure I is a vertical section of the lubricator and rail. Fig. II is a plan of the rail and guide-plate. Fig. III is aplan, the guideplate being removed. Fig. IV is a section on the line A B, Fig. III. Fig. V is a section of the guide-plate. Fig. VI is a section of tubular form of the lubricator. Fig. VII is a top View of tubular lubricator; Figs. VIII and IX, sections on lines C D and E F, Fig. VII; Fig. X, section on line R S, Fig. VI, showing the position of the spindles in the tube.

The spindles of rin g-spinnin g frames, mules, and other spinning and twisting machines have heretofore revolved in a cup-shaped step or bearing, which receives the conical-shaped base of the spindle, the steps being detached fromeach other and secured to the lower rail of the spinning-frame.

A large quantity of oil is required to lubricate the spindles, which run at a very high velocity, and as it is necessarily applied to each step separately, great Waste occurs both in the application of the oil .to the detached steps and from its .being thrown o" by centrifugal force. By the use of iny improvement these difficulties are obviated; a constant and uniform suppl y of oil is insured,` and its waste entirely prevented. This is effected by dispensing with the detached steps, and supporting the lower end ofthe spindle by a suitable metallic guide-plate, which keeps it in place, while the base of the spindle projects below the guide-plate and rests upon a thin steel plate, being embedded (between the bottom plate and the guide-plate) in a strip of felt or other fibrous substance, which is saturated with oil or other lubricating material.

A longitudinal slot or cavity of the form shown in Fig. IV is made in the top of the lower rail, G, of the frame, and receives the hardened steel bearing or guide plate M, Fig. V, in which are holes T T', Fig. II, of such size as will prevent any lateral vibration, and at the same time allow the ends of the spindles L to project below the plate M, pass throughthe felt or other brous substance, I, Figs. I and III, and tnd a bearing on the face of the bottom plate, H. The slot extends the whole length of the rail, without any partitions or divisions. The base-plate H and the strip of felt I' also extend from end to end of the elongated box. The guide-plate M also forms a cover to prevent the evaporation of the oil, with which the felt I is saturated. It may be made in several pieces for convenience of removal, and it is also furnished with countersunk holes U, through which the oil or other lubricator is poured upon the felt.

The position of the spindles L, when in operation, is shown in Fig. I. They extend below the guide-plate M and through the saturated felt I, with their bases resting upon the bottom or bearing plate H.

Oil is usually employed as alubricator, but weten-soap and water-alkaline solutions, or other substances may be used, and in cases where the cavity in the rail is liable to rust it is lined with a tin box, which conforms to the shape of the cavity, the respective posi tions of the guideplate, the felt, and the bearing-plate remaining the same.

To prevent the oxidation of the spindles about one inch in length of the lower ends is electroplated with copper, brass, or any metal less liable to be corroded than the steel of which they are made.

In some cases I prefer to make the lubricator in tubular form, as shown in Figs. VI to X. The tube N lies in a groove made in the rail, and receives the ends of the spindles L L in the holes P P. Felt or Wick-yarn, O, is drawn through the tube, and its ends are closed with a screwcap, Q, to prevent the oil from escaping when the ber is saturated. The end of the spindle rests in the tube in the position shown in Fig. X, and when it is desirable to liavea larger surface 'in contact with the spindle the Walls of the tube are made thicker at the top and bottom, as at -V W, Figs. VIII, IX, X.
