Improvements in Cap Bars for Mules, and Ring and other Spinning
and Doubling Frames.
I, ROBERT TAYLOR, Junior, of the Firm of Asa Lees and Company Limited,
of 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 the cap bars for the leather covered or other top rollers
employed in mules, and ring and other spinning and doubling frames and the object
of my invention is to avoid loss by breakage and to facilitate the operation of
machining and finishing the cap fingers.
In ordinary practice the cap fingers and cap bars are cast together in one piece,
and one objection to this course lies in the difficulty of machining the fingers, as the
castings are of awkward shape and liable to be easily broken.
To effect my object I cast the bar with feet in one piece to receive the cap fingers
which are cast or otherwise made separately and these parts are then secured
together in any convenient manner.
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.
Fig. 1 is a plan and Fig. 2 an end view of a cap bar made according to my
invention and Fig. 3 is an end view of the same slightly modified.
Fig. 4 is a plan of another modification and Fig. 5 is a view of the cap bar shown
in Fig. 4.
In these views, a is the main portion of the cap bar, a¹ the pivots on which it
is mounted, a' the feet shown drilled at a³, Figs. 1 and 2, and partly cut away at a³
in Fig. 3, to receive the prepared ends 61 of the cap fingers which are separate
parts each secured by a set screw c. In Figs. 1 and 2 the screw c is threaded through
the foot a² and its end simply bears against the shank of the cap finger b which
is fitted into a recess in the part a'; whereas in Fig. 3 the screw c passes freely
through the foot a² and its end enters the shank which is tapped to receive it, a
washer c is placed under the head of the screw cand the prepared shank is pulled
against the prepared surface of the foot a² by tightening the screw c. The fingers b
are slotted as usual at 62 to receive the adjustable cap nebs which are secured to
the fingers by screws e.
By securing the cap fingers to the feet a² of the cap bars in the manner shown
and described or in an equivalent manner the fingers can be much more readily
machined and finished and should a finger be broken it can be very readily and
cheaply replaced.
In place of making the feet as shown in Figs. 1, 2 and 3 the cap bar could have
projections a² cast upon its side or edge to receive the prepared ends of the fingers
as shown in Figs.
and 5.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I wish it to be
clearly understood that I do not claim broadly the construction of cap bars and
fingers as separate parts, as I am aware that prior to my present invention cap bars
and fingers have been made separately, but in such case the cap bar was a plain rod
or bar without feet or projections to receive the fingers which were fitted on the rod
n

page_text: and secured by screws and consequently the result was not satisfactory and I
declare that what I claim is :-
The construction of a cap bar formed with feet or projections into or to which
the fingers are fitted and secured substantially as herein shown and described.
