We, JOSEPH HORROCKS, and EDWIN HORROCKS, of Osborne Street, Park Road,
Bradford, in the County of York, Picker Manufacturers do hereby declare the naturo
of this invention to be as follows:-
This invention relates to improvements in the picking motion or mechanism for
actuating the picker in looms for weaving, and its object is to provide a durable and
efficient motion of simple construction and capable of allowing the loom to be turned
backwards without actuating the shuttle.
For this purpose we employ an arm, disc or wheel fixed on the end of the tappet
shaft and provided with a slot in which a stud is mounted carrying an antifriction
roller. A lever pivoted on an adjustable stud mounted in a slot in the loom frame and
normally lying in an approximately vertical position is vibrated at each revolution of
the tappet shaft by the said antifriction roller striking the lower end thereof. The
upper end of the said lever is preferably provided with an antifriction roller placed in
contact with an antifriction roller mounted on an arm projecting from a short vertical
picking shaft carrying the picking stick.
The various parts of the above described mechanism are so relatively arranged that
at each revolution of the tappet shaft when a pick is required to be made the said anti-
friction roller carried by the arm mounted on such shaft actuates the lever in contact
with the arm on the said picking shaft and partly rotating such shaft communicates
the requisite motion to the picking stick to impel the shuttle.
In order to impart an accelerating motion to the picking stick the upper end of the
above mentioned lever is arranged to slide along the arın towards the picking
shaft as it is actuating the same thus the speed of the pick is proportionately
accelerated.
The lower end of the said lever is provided with a pendent piece hinged thereto
and capable of being raised by the arm on the tappet shaft when the loom is turned
back to allow such arm to pass without actuating said lever.
It is obvious that a similar arrangement of mechanism will be required at the other
side of the loom.

We, JOSEPH HORROCKS, and EDWIN HORROCKS, of Newall Street, Manchester
Road, Bradford, in the County of York, Picker Manufacturers, 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 relates to improvements in the picking motion or mechanism. for
actuating the picker in looms for weaving, and its object is to provide a dourable and
officient motion or arrangement of simple construction and capable of allowing the
loom to be reversed without actuating or disturbing the shuttle.
The invention consists of the arrangement hereinafter described in which the picking
stick is mounted on a short vertical shaft provided with an arm near the top adapted
to engage with the upper end of an approximately vertical lever provided with a loose
pawl or pendant piece and actuated at the required time by an arm or its equivalent
projecting from the shaft commonly called the tappet shaft.
In the accompanying drawing Figure 1, represents a side view of such parts of a
loom as are necessary to illustrate the application of our improvements. Figure 2, is
a back view of one of the side frames and attachments thereto. In each figure
similar letters of reference indicate corresponding parts.
The picking stick A is connected in the ordinary manner to the top of a compara-
tively short vertical shaft B mounted in bearings C secured to the frame D. An
arm E projects at right angles from the shaft B and provided with a conical or
taper anti-friction roller F which engages with the anti-friction roller G mounted on
the top of the lever H pivoted on the stud J projecting from the loom frame D. An
arm K projecting from the end of the tappet shaft L carries an anti-friction roller M
which at each revolution of the tappet shaft bears against the pawl N, bereinafter
referred to, hinged to the lower end of the lover H thereby oscillating such lever and
thus communicating the necessary motion to the picking stick A through the medium
of the above described mechanism.
From the foregoing description it will be seen that as at the beginning of the pick
(the position represented in the drawings) the roller G bears against the extremity of
the roller F, but as the motion is extended it rolls along F and at the termination of
the pick has almost reached the inner end of such roller, thus proportionately accelera-
ting the speed of the picking stick which enables it to communicate a smooth throw
to the shuttle without jerking it. And it is obvious that the anti-friction
rollers F, G and M greatly reduce the friction of the working parts.
The above mentioned pawl or pendant piece N hinged to the lower end of the
lever His provided to enable the loom to be reversed and so allow the arm K to turn
backwards and by raising the pawl N pass the lever H without operating it.
It is obvious that a similar arrangement of mechanism will be required at the other
side of the loom.

page_text: 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 what we
claim is :
1. The general construction or arrangement of picking mechanism consisting of an
arm mounted upon the tappet shaft adapted to oscillate an approximately vertical
lever provided with a pawl and engaging a projection on a vertical picking shaft,
substantially as herein shown and described.
2. The pawl or pendant piece N, arranged substantially as herein shown and
described and for the purpose specified.
3. The combination with the said picking mechanism, of the anti-friction
rollers F, G and M, substantially as herein shown and described.
