IMPROVEMENT IN THE LU-BRICATING OF SPINDLES.

Specieation forming part of Letters Patent No. 40.678, dated November 24, 1863.

.To all whom it may concern:

Be it known that I, JAMES EATON, of Boston, in the county of Suffolk and State of Massachusetts, have invented an Improve- Inent in Lubricators; and I do hereby declare that thefollowin gis afull and exact description thereof', reference being had to the accompanying drawings,` making a part of this specication, and to the letters and figures marked f. thereon.

Figure I is a plan of the mechanism; Fig. II, an elevation of the fixed part of the same; Fig. III, an elevation ofthe movable lubricator; Fig. IV, a plan of the same; Fig. V, a section on the line A B, Fig. I; Fig. VI, an enlarged section of a spindle-bearing.

The object of my improvement 1s to afford a constant supply ot' oil to spindles while they are in motion, by which they are always kept in good running order, instead ot' being at one time nooded with oil and at another nearly dry. At least one-halt' the oil now required fir lubricating spindles is saved by my improvement.

I am aware that various kinds of fibrous substances have been used for conveying oil to bearings, as inrailway-axles, te, and my improvement relates merely to the manner of applying the oil, fat, tallow, or other substance used for this purpose. The mechanism for effecting this is shown in the drawings. The rail C, that attords a bearing for the spindles, extends across the mule or spinning.

frame, and the bearings, instead ot' being circular, as usual, are semicircular, as at D, at the point of contact with the spindle, the whole form of the bearing being shown enlarged in Fig. VI. This form is used for the purpose ot' exposing the spindle. 'as at S, Fig. II, in such a position that the oil may be readily applied.

The lubrcator consists of a case, E, Figs. I, l

III, IV, V, which has atop, bottom, and front side, and within it a piece of felt, sponge, or other suitable fibrous substance, G, is placed,

the breadth of the case and inclosed felt being equal to the height or length of the bearing. Clamp-springs F F are attached to the rail and project from it a distance equal to the breadth of the case E. The spindles S S are held in close contact with the bearings D by the driving-bands, and need no support upon the opposite side. is slipped between the clamps, and the open or exposed side of the spindles rests in contact with the felt G, which is saturated with oil. The top ot' the case projects over the rail, as seen in Fig. V, and protects the bearing from dust and dirt. The clamp-springs F are pressed forward when closer contact of the felt with the spindle is required. The movable case can be readily lifted out, and the spindles can be adjusted with great facility by the use of my improvement.

, Although [consider the bearing ot' the. spindle upon one side (while the other is exposed to the lubricator) as sufficient to insure its steady action, an additional bearing may be formed by making the edges of the semicircular cavities at H in the4 top ot the case of suitable thickness for this purpose.

When bearin gs are made in the case, as

above named, it will be necessary to give it av iirm support and a iixed position with reference to its distance from the spindle. This may be effected by'form-ing a rabbet in the rail, as at- R, Figs. II and V, and fitting the top otl the case accurately to it.

What I claim, and desire to secure by Letters Pat-ent, is-

The movable case, containing the lubricating substance, and having one of its sides open, in combination with the sernieircular main bearing D, which allows a spindle tov come in contact with the lubricating subi stance, substantially as herein described.
