PROVISIONAL SPECIFICATION.
Improvements in Spinning and Twisting Machinery.
We, JOHN DAWSON and ROBERT SOUTHWORTH DAWSON, both of Bower
Green Shed, Leeds Road, Bradford, in the County of York, Spinners, do hereby
declare the nature of this invention to be as follows
-
This invention relates to that class of machinery for spinning and twisting
fibrous material in which tension pulleys supported by pendant brackets or castings
are employed to regulate the tension of the driving bands or tapes, and its object is
to more fully utilize the weight of said bracket and the tension pulley carried
thereby to keep the said bauds on tapes at the tension required.
For this pui pose we suspend each bracket considerably on one side in relation
to the axis of its tension pulley that is say it is suspended from a rod or its
equivalent not immediately above the normal position of the tension pulley but
more vi less on one side in the direction of the side of the pulley round which the
band passes. By this means the weight of the bracket winch naturally tends to
swing down and rest beneath its point of suspension keeps the band or tape at the
tension required.
The bracket may be formed in two pieces and the upper one may be oxtended or
bent towards the said rod and be hooked on suspended theicon.

Improvements in Spinning and Twisting Machinery.
We, JOHN DAWSON and ROBERT SOUTHWORTH DAWSON, both of Bower
Green Shed, Leeds Road, Bradford, in the County of York, Spinners, do hereby
declare the nature of this invention and in what manner the same 19 to be
performed, to be particularly described and ascertained in and by the following
statement:-
This invention relates to that class of machmety for spinuing and twisting
fibrous material in which tension pulloys supported by pendant brackets or castings
are employed to regulate the tension of the driving bauds on tapes, and its object is
to more fully utilize the weight of the said bracket and the tension pulley carried
thereby to keep the said bands on tapes at the tension required
For this purpose we suspend each bracket considerably on one side in relation
to the axis of its tension pulley that is to say it is suspended from a rod or its
equivalent not immediately above the normal position of the tension pulley but
more or less on one side in the duection of the side of the pulley round which the
band passes. By this means the weight of the bracket which naturally tends to
swing down and test beneath its point of suspension keeps the band or tape at the
tension required.
The bracket may be formed in two pieces and the upper one may be extended or
bent towards the said 1od and be hooked or suspended thereon.

page_text: Reference is to be had to the accompanying sheet of drawings forming a part of
this Specification, in which similar letters of reference indicate corresponding parts
in each of the figures.
Figure 1, represents a cross sectional view of such portions of a spinning frame
as are necessary to illustrate the application of our improvements.
Figure 2, represents a plan view of the same.
The spindles A, the tubes B, the wharles C, the lifter plate D and the
cylinder E are of the usual type.
The tension tollets F and the brackets II are preferably arranged as shown in
our previous Specification No 18,691 dated the 3rd day of October 1894. The
pendant pioce L however is made with an approximately horizontal projection L2
(or its equivalent) provided with claws L3 adapted to be hooked on the rod R
aud be suspended thereby. The length of the tape N is such that each bracket is
hept approximately in the position shown in relation to the rod R consequently
the weight of the bincket, which normally tends to swing down beneath its point
of suspension, keeps the tape at the required tension and a tension weight is not
1equired.
Having now particularly described and ascertained the nature of our said inven-
Lion, and in what manner the same is to be performed, we declaio that what we
claim is.
In spinning and twisting machinery, suspending the tension rollet in the manner
herein shown and described and for the purpose specified
