Improvements in and relating to the Spindle Bolsters of Self Acting
Mules and Twiners.
I ROBERT TAYLOR of the firm of Asa Lees and Company Limited of Oldham in
the County of Lancaster Manager, do hereby declare the nature of this Invention to
be as follows:-
The object of my Invention is to insure the thorough and automatic lubrication of
the spindles in the bolsters of self acting mules and twiners.
To effect this object I employ an open bolster that is to say, a bolster having spindle
holes open at the front sufficiently to expose the spindles but not so open as to permit
the spindles to be taken out at the front. I attach a piece of fannel or other suitable
material to the inner side of the upper portion of the ordinary baywood rib or top
board which is divided longitudinally into two pieces which are preferably hinged
together. The piece of Hannel or other material is saturated with oil or other
lubricant and lies in contact with and so effectually and automatically lubricates the
exposed portions of the revolving spindles.
am aware that open bolsters have been used prior to the date of my present
Invention and I wish it to be understood that I lay no claim broadly to open bolsters
but only in combination with the lubricating arrangement as aforesaid.
Dated this 15th day of June 1888.

I ROBERT TAYLOR of the firm of Asa Lees and Company Limited of Oldham in
the County of Lancaster Manager, 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 :-
The object of my Invention is to insure the thorough and automatic lubrication of
the spindles in the bolsters of self acting mules and twiners.
To effect this object I employ an open bolster, that is to say, a bolster having spindle
holes open at the front sufficiently to expose the spindles but not so open as to permit
the spindles to be taken out at the front. I attach a piece of flannel or other suitable
material to the inner side of the upper portion of the ordinary baywood rib or top
board which is divided longitudinally into two pieces which are preferably hinged
together. The piece of flannel or other material is saturated with oil or other
lubricant and lies in contact with and so effectually and automatically lubricates the
exposed portions of the revolving spindles.
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.
Figure 1 is a front elevation of part of the spindle bolster of a self-acting mule
to which my improvements are applied. Fig. 2 is a plan and Fig. 3 a transverse
vertical section of the same.
In these views. a designates the spindle bolster which is carried by a bolster rail b
and has spindle holes which are placed at equal distances apart and are drilled near
the front edge of the bolster a and the metal cut away so as to expose the
spindles c without however allowing them to be taken out at the front of the
bolster. The strip of flannel or other suitable material d is secured to the upper
portion e of the baywood rib or top board and the piece e is by preference hinged
at e as shown to the lower portion e². The spindles c are supported below as usual
in the footstep f.
It will be readily seen that after the flannel strip d has been saturated with
lubricant and the piece e has been turned into the position shown best in Fig. 3
to press the said strip d against the spindles that the latter will be thoroughly and
automatically lubricated as they revolve in the bolster.
I am aware that open bolsters have been used prior to the date of my present
Invention and I wish it to be understood that I lay no claim broadly to open bolsters
but only in combination with the lubricating arrangement as aforesaid.

page_text: 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. In a self acting mule or twiner, the combination with a bolster having open
spindle holes, of a strip of flannel or other suitable material attached to the ordinary
bay wood rib or top board for the purpose of supplying lubricant to the spindles
substantially as specified.
2. The combination with the bolster a having open holes as specified for the
spindles C₁ of the flannel or other strip d attached to the hinged piece e substantially
as and for the purpose herein described and as illustrated by the accompanying
Drawings.
