IMPROVEMENTS IN LOOM PICKERS
Year: 1882

page_text: LETTERS PATENT to Henry Tetlow of Miles Platting in the County of
Lancaster and Joseph Holding of Lower Broughton in the Same County for
au Invention of "IMPROVEMENTS IN LOOM PICKERS "
PROVISIONAL SPECIFICATION left by the said Henry Tetlow and Joseph
Holding at the Office of the Commissioners of Patents on the 28th November
1882.
HENRY TETLOW of Miles Platting in the County of Lancaster and JOSEPH
HOLDING of Lower Broughton in the same County "IMPROVEMENTS IN LOOM
PICKERS
"
Our Invention relates to the pickers employed in looms for weaving and has for
its object to lessen the destructive force of the blow when the shuttle is struck by
the picker in order that the durability of the picker may be increased and that the
tendency for the shuttle to fly out of the box and for the cops to be damaged may
be lessened. To obtain these results we provide the picker with a yielding spring
buffer against which the shuttle tip strikes. The said buffer may be made of
leather, wood or other suitable material and be fitted to slide in a recess in the
shuttle or in a part secured thereto. When the shuttle strikes the buffer the
spring yields and the force of the shuttle is absorbed with less concussion than in
the case of the ordinary picker. In one construction we make the buffer of buffalo
hide moulded with a collar or head against which the picker strikes and with
a shank which slides in the picker body and is acted upon by a spiral or other
suitable spring. The picker body may be a wooden block bored to slide upon the
picker spindle and formed with a hole for the attachment of the band or otherwise
fitted for attachment thereto.

HENRY TETLOW of Miles Platting in the County of Lancaster and JOSEPH
HOLDING of Lower Broughton in the same County "IMPROVEMENTS IN LOOM
PICKERS
"
Our Invention relates to the pickers employed in looms for weaving and has for
its object to lessen the destructive force of the blow when the shuttle is struck by
the picker in order that the durability of the picker may be increased and that the
tendency for the shuttle to fly out of the box and for the cops to be damaged may
be lessened. To obtain these results we provide the picker with a yielding spring
buffer against which the shuttle tip- strikes. The said buffer may be made of
leather, wood or other suitable material and be fitted to slide in a recess in the
shuttle or in a part secured thereto. When the shuttle strikes the buffer the
spring yields and the force of the shuttle is absorbed with less concussion than in
the case of the ordinary picker.
In order that our invention may be fully understood we will refer in this place
to a sheet of drawings which we have attached hereto and which represent a
picker drawn to an enlarged scale. In the said drawings Fig 1 represents a side
view Fig 2 a section and Fig 3 an end view of our improved picker. In the said
Figs a is the body of the picker which in the example is supposed to be made of
wood but it may be made of a moulded material or of any material found to be
suitable. In the said body is formed a hole b for the attachment of the picking
band. The method of attachment or the preparation therefor may be varied. The
lower part of the picker is bored to receive a piston c consisting of a metal tube
which is closed at the outer end by means of a metal plate and is screwed or
securely attached to a buffer or head d of leather, buffalo hide, wood or other
suitable material. Within the said piston is a spiral spring e which presses the
buffer d outwards against a stop plate f which is screwed or secured to the front of
the picker and projects in front of the said head sufficiently to prevent the piston
from leaving the picker. It will be seen that the buffer d is formed with a flat
side which slides in contact with the face a' of the picker whereby the piston is
steadied in its movements and is prevented from rotating. If preferred however
the piston may be free to rotate. When the piston is at work the buffer d of the
piston strikes the shuttle tip when the shuttle is being driven out of the box and
by the yielding of the spring imparts a yielding or clastic blow to the shuttle and
on the other hand when the shuttle tip strikes the buffer d the yielding of the
spring lessens the force of the blow and the shuttle is brought to rest with less
shock than when the ordinary picker is used.
We do not confine ourselves to the form of the spring and may use a volute
spring made of flat steel or we may use other material than steel in the formation
of the spring. The piston c may be solid instead of tubular and may be in one
piece with the buffer or head d as for example we may mould the buffer d and the
piston or shank c in one piece from buffalo hide.
Having now fully set forth and indicated the nature of our said invention and
the manner in which we carry the same into practical effect we would have it to be
understood that we claim :-
First the picker constructed as set forth and indicated herein before and in and
by the accompanying drawings.

page_text: And secondly the picker fitted with a spring or elastic buffer so as to give
and receive elastic blows to and from the shuttle substantially as set forth and
indicated.
In witness whereof I the said Henry Tetlow for myself and on behalf of the
said Joseph Holding have hereunto set my hand and seal this twenty-fifth
day of May in the year of our Lord one thousand eight hundred and
eighty-three
igned, sealed and delivered
