Improvements in the Bolster Bearings of Spindles for Self Acting
Mules and Twiners.
I, ROBERT TAYLOR, Junior, of the firm of Asa Lees and Company Limited, of
Soho Iron Works, Oldham, in the County of Lancaster, Engineer, do hereby
declare the nature of this invention, and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement :-
My invention relates to improvements in the bolster bearings of spindles for self
acting mules and twiners, and the chief object of my improvements is to ensure the
thorough lubrication of the spindle bolsters by simple and automatic means.
I accomplish this object by cutting away the front of each bolster bearing and
forming a trough or receptacle for lubricant which can thus come in contact with
the exposed portion of the spindle and lubricate it.
And in order that my invention may be fully understood and readily carried into
effect I will describe the accompanying sheet of drawings reference being had to
the figures and letters marked thereon.
Figures 1, 3, and 7 are cross sections and Figs. 2 4, 6 and 8 are plan views of
spindle bolsters and bearings constructed according to my invention.
Similar letters refer to similar parts throughout the several views, in which:-
a designates the bolster rail; b the spindle, c several forms of my improved
bolster bearings, and d the screws by which said bearings are secured to the
bolster rail a.
In the arrangement illustrated by Figs. 1 and 2 each bolster bearing c consists
of a small box or receptacle through which the spindle & passes. This box or
receptacle is filled with solidified oil or grease, or with cotton waste or other
suitable absorbent material which may be saturated with oil to lubricate the
spindle passing through the bearing, and is closed with a cover or lid e hinged
thereto at e. Each box or receptacle may have a separate cover or lid, but I
prefer to employ one plate e to cover a number of the bearings.
In the arrangement illustrated by Figs. 3 and 4 each bolster bearing c is formed
with a projecting portion c¹ through which a hole is drilled to allow lubricant
placed in said portion c¹ to come in contact with the spindle b. The hole in the
part is closed by a cap or cover e.
The arrangement illustrated by Figs. 5 and 6 is a modification of Figs. 1 and 2
and the only difference is that instead of having a separate box or receptacle for
each spindle the bolster bearing c is lengthened to form a trough to receive the
lubricant for any convenient number of spindles.
Similarly Figs. 7 and 8 illustrate a modification upon the same lines of Figs. 3
and 4 the trough to receive the lubricant being formed in front of the bearing c
and the lubricant passing through holes c¹ to each spindle b.
In each of the arrangements described and illustrated the lubricant comes in
contact with the portion of the spindle exposed in its bolster bearing and con-
sequently the spindles are kept constantly and effectively lubricated.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
:-
1. The combination with a spindle bolster bearing open or partially open on one
side, of a trough or receptacle for lubricant which comes in contact with and
lubricates the portion of the spindle or spindles exposed by said open bearing
substantially as herein set forth.
2. The several constructions and arrangements embodying my improvements in

page_text: the bolster bearings of spindles for self acting mules and twiners substantially as
and for the purposes herein described and as illustrated by the accompanying
drawings.
Dated this 9th day of December 1892.
