PROVISIONAL SPECIFICATION.
Improved Self-acting Stop Gear for Manilla Hemp Drawing
Machines.
DANIEL LISTER 85 Ash Grove Wavertree Liverpool Mechanical Engineer
I do hereby declare the nature of this invention to be as follows:-
My invention is for instantly stopping manilla hemp drawing machines from
breaking down which is caused by the hemp taking its wrong course in the machine
and going round the bars of the slow sheet of the machine, thus causing the said
bars to take the wrong course and break some part of the machine.
To prevent these breakages I have a casting bolted to the frame side of the
machine which carries a cross bar, the cross bar end coming through the frame side
with a fork firmly attached to it and opposite to the lever on the starting rod of the
machine in the cross bar I have a small catch which holds the cross bar in position
when the machine is working all right, from the other end of the cross bar I have
an arm coming down with a wheel working on a stud close above the revolving bars
of the machine.
As soon as the hemp gets fast round the bars of the slow sheet of the machine it
lifts the bars which come in contact with the small wheel which latter relieves the
catch on the cross bar and as soon as this is relieved a spring forces the cross bar
against the starting lever of the machine which instantly stops it and prevents
breakages as before mentioned thus saving a large amount of labour and material
in repairs.

Improved Self-acting Stop Gear for Manilla Hemp Drawing
Machines.
I, DANIEL LISTER of 85 Ash Grove Wavertree Liverpool 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:-
The object of my invention is to instantly stop manilla hemp drawing machines,
and thereby prevent break-downs, should the hemp take a wrong course in the
machine and go around the bars of the slow sheet, thus causing said bars to be
thrown out of position and break some part of the machine.
But in order that my invention may be better understood reference is made to
the accompanying sheet of drawings which represents a section of a manilla hemp
drawing machine provided with my self acting stop gear.
In carrying out the invention I bolt to one side frame (A) of the machine, a
suitably shaped casting (B) to carry a cross bar (C), one end of which projects
through said frame (A) and is secured to a fork (D) in which is loosely arranged
the lever (E) connecting with the starting rod (F) of the machine, whilst the other

page_text: end of said cross bar carries a vertical arm (G) in the lower portion of which is a
stud (H) to support a small wheel (I) placed just above the revolving bars (J) of
the machine. In the cross bar is a notch (K) to engage with a correspondingly
shaped projection formed on the casting (B) so as to retain said cross bar in position
when the machine is working all right. A spiral spring (L) draws the cross bar
outwardly when it is released from the catch.
To operate my invention, say the hemp has got fast round the bars (J) of the
slow sheet of the machine, the effect is, that said bars are lifted and come in
contact with the wheel (I) and also raises the arm (G) sufficiently to release the
catch, the spring (L) then comes into action and draws the cross-bar forwardly, so
as to force the lever (E) outwardly, thereby turning the starting rod (F) which
instantly stops the machine.
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 :
A self acting stop gear for manilla hemp drawing machines consisting of the
cross bar (C) having an arm (G) provided with a wheel (1), on one end, and a
fork (D) on the other, together with the spring (L) and catch, all arranged and
combined, as and for the purposes herein set forth.
