COMPLETE SPECIFICATION.
Improvements in Apparatus for Preventing "Singles" in Preparing
Spinning, Doubling, and Winding Fibrous Materials.
I WILLIAM NIELD of 79 Rochdale Road. Shaw near Oldham in the County of
Lancaster Mule Overlooker do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascertained
n and by the following statement:-
This invention relates to improvements upon an invention for which Letters Patent
No. 11586 bearing date 11th August 1888 were granted to Thomas Bentley of which
Letters Patent I am assignee.
The object of my invention is to simplify the manufacture of the apparatus to
reduce its cost and increase the efficiency thereof.
In carrying out these improvements I dispense with the plate marked, on the
drawings annexed to the said Specification No. 11586,, the guide eyes c and the
traversing vertical plate e¹ which I am enabled to do by constructing the apparatus in
the manner hereinafter described.
The precise nature of my invention and the manner in which the same is to be
performed or carried into practical effect will be readily understood on reference to
the sheet of drawings hereunto annexed and the following explanation thereof.
Fig. 1 is a partial section and
Fig. 2 a plan view of the improved apparatus.
Fig. 3 is an elevation of one of the fixed guide plates between which the weighted
balanced levers work, and
Fig. 4 is a similar view and
Fig. 5 a plan view of one of the weighted levers.
I mount the whole apparatus on a rail or plate a (Figs. 1 and 2) to which a
traversing movement is given in any convenient manner.
This rail or plate a I place on the side next to the creel and 1 dispense with the
guide eyes (marked c on Bentleys drawing) by making holes c (Fig. 1) through
the same for the passage of the slivers.
Next to this plate I mount a catch lever b provided with two projections 61 and 6"
which prevent it and the weighted balanced levers h, h' from falling too low, either
forwards or backwards.
The fixed guides d, and d' (Fig. 3) between which the balanced levers work are
held in position by means of a square bolt e the nut of which is screwed up tight.
The guide d nearest to the rollers is provided with a forked arm d" for traversing
the doubled sliver between the rollers.
The weighted balanced lever h, (Figs. 4 and 5) is made with a round bole k which
works on a bush (see detached view Fig. 6) which is slightly thicker than the
lever h; the catch band the lever works upon a similar bush so that when the
nut of the bolt e is screwed up tight it will bind the two guide plates d and d¹ and
allow the balanced levers to work freely.
I make these balanced levers of sheet steel punched out to the required form and
I drill in the upper edge thereof taper holes (see Fig. 5) into which I drive the needle
points.
It will be understood that this invention does not stop the frame when a single
sliver breaks down but only breaks the other sliver or slivers and thus prevents any
single "from going through.

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 :-
"
The several improvements in the construction of apparatus for preventing "singles
in preparing, spinning, doubling and winding fibrous materials substantially as herein-
before particularly described and illustrated by the drawings annexed.
Dated this 26th day of March 1890.
