PROVISIONAL SPECIFICATION.
Improvements in Drawing Frames for Fibrous Materials.
We, EDMUND TWEEDALE, SAMUEL TWEEDALE, and JOSEPH SMALLEY, of
Globe Works, Castleton, near Manchester in the County of Lancaster, Machine
Makers, do hereby declare the nature of this invention to be as follows:-
This invention comprises a new and improved construction and arrangement of
parts for raising and supporting the weights suspended from the top rollers of
drawing frames and for facilitating the renewal of broken parts. According to
bis invention we form holes in each end of the flat bars used for raising the roller
weights; these holes are placed near the top edge of the bar to caused them to
hang without tilting sideways.
Through these holes we put a rod and support each end of this rod by links
from an eccentric shaft that is connected to the sides of the roller beam.
Hitherto the holes in the hooks on which the roller weights are hung have
surrounded the flat bar and in case any of the hooks require renewal the bar has
had to be removed. To obviate this we form the hole in the hooks for the reception
of the bar with an opening on one side to enable them to be taken off or put on
without disturbing the bar from its working position.

Improvements in Drawing Frames for Fibrous Materials.
We, EDMUND TWEEDALE, SAMUEL TWEEDALE, and JOSEPH SMALLEY, of
Globe Works, Castleton, near Manchester, in the County of Lancaster, Machine
Makers, 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 :-
This invention comprises a new and improved construction and arrangement of
parts for raising and supporting the weights suspended from the top rollers of
drawing frames, and for facilitating the renewal of broken parts. According to
this invention we form holes in each end of the flat bars used for raising the roller
weights: these holes are placed near the top edge of the bar to cause them to
hang without tilting sideways.
Through these holes we put a rod and support each end of this rod by links
from an eccentric shaft that is connected to the sides of the roller beam or rail.
Hitberto the holes in the hooks on which the roller weights are hung have
surrounded the flat bar and when any of the hooks require renewal the bar has bad
to be removed. To obviate this we form the hole in the hooks for the reception of
the bar with an opening on one side to enable them to be taken off or put on without
disturbing the bar from its working position.
In order that our improvements may be more clearly understood reference is
made to the accompanying sheet of drawings wherein Fig. 1 is sectional elevation

page_text: of such parts of a drawing frame as is necessary to illustrate our invention, and
Fig. 2 is front elevation of same. A represents the top rollers of a drawing
frame on the axles of which are suspended hooks B connected by screwed rods C
to our improved hook D to the bottom of which the ordinary weights E are
suspended.
F are the flat bars made with suitable form of holes at each end for the reception
of rods G. The holes in each end of the flat bars are made above the centre or
near the top edge, so that more weight of metal is below the holes than above
them, by which means the bars will hang vertically without tilting sideways.
Each end of the rods G are supported and carried by links H which in turn are
supported by an eccentric shaft I mounted in brackets J connected to the sides of
the roller beam or rail K, therefore when it is necessary to remove the pressure of
the weights E off the top rollers A the handles L on the eccentric shaft are turned
partially around in doing which the rods G and flat bars F are raised, causing the
top edge of the said flat bars to bear on the pins or rollers M in our improved
hook D by which means the weights are for the time being supported upon the top
edge of the flat bars F.
Instead of the hook D surrounding the flat bars as is the case with those hooks
at present in use, our improved hook is made with an opening or aperture on one
side which permits any one of the hooks being removed without disturbing the bars
from their working position.
Fig. 3 is a front view of our hook and Fig. 4 side view of same on an enlarged
scale.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
Firstly. For removing the pressure of weights E off the top rollers in drawing
frames, the combination therewith of eccentric shaft I, links H rods G and
flat bars Farranged and operating in the manner described and shewn in the
drawings.
Secondly. The construction of hooks D having an opening or aperture on one
side as shewn and for purposes described.
