I THOMAS BROMLEY of 80 Blackburn Street, Bolton in the County of Lancaster,
Patent Picker Manufacturer, do hereby declare the nature of my Invention for
"IMPROVEMENTS IN THE CONSTRUCTION OF PICKERS AND STOPPERS EMPLOYED IN
LOOMS FOR WEAVING," to be as follows:-
My invention relates to improvements in single and double box pickers employed
in "overpicked" and "underpicked" looms, and in stoppers against which they
strike; the latter being placed on the outer ends of the spindles on which the
pickors slide; which are constructed or manufactured as usual from Buffalo Hide,
Brown Leather, Cloth, or other suitable materials, and consists in strengthening
the weak and wearing parts considerably, with the result of prolonging the use of
the pickers and stoppers, thereby effecting economy, both as regards labor and
expense.
It is well-known that those parts of a picker against which the shuttle tip
strikes, and also where the spindle passes through, are often worn away or burst
out long before the picker is worn out. To overcome these defects I press by
ordinary means a solid semi-circular or other conveniently shaped hoop or boss,
round the above named parts on the picker in an embossed form, which rises above
the face of the picker, giving greater additional strength to the same, thereby
enabling the picker to more firmly resist the action of the shuttle tip and spindle.
Round the outside of the holes in the picker head through which the spindle
passes, similar embossed hoops or bosses are provided, thereby increasing the
bearing surface, as well as the striking part.
I further strengthen the pickers by forming suitable embossed, corrugated, or
semi-circular bands or ridges between the embossed hoops or bosses round the part
where the shuttle tip strikes and those round the spindle holes in the picker head.
In some cases where necessary I continue the aforesaid bands or ridges round other
portions of the picker, such as, to the top side of the head on each side, or other-
wise, thereby increasing the strength of the sides and ends of the pickers, which
prevents them from bursting with the strain to which they are subjected.
In applying my improvements to the stoppers placed on the picker spindles, and
against which the pickers strike, I form the embossed hoop or boss round the holes
on the spindles, thereby increasing the strength of the part struck which prolongs
their existance, as well as that of the pickers.

page_text: I THOMAS BROMLEY of 80 Blackburn Street, Bolton in the County of Lancaster,
Patent picker Manufacturer, do hereby declare the nature of my Invention for
"IMPROVEMENTS IN. THE CONSTRUCTION OF PICKERS AND STOPPERS EMPLOYED IN
LOOMS FOR WEAVING," and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:―
My invention relates to improvements in single and double box pickers employed
in " overpicked" and "underpicked" looms, and in stoppers against which they
strike, the latter being placed on the spindles on which the pickers slide. Pickers
and stoppers made on my improved principle are manufactured as usual from
Buffalo Hide, Brown Leather, Cloth, or other suitable materials, and consists in
strengthening the weak and wearing parts, with the result of prolonging their use,
thereby effecting economy both as regards labor and expense.
It is well known that those parts of a picker against which the shuttle tip
strikes and also where the spindle passes through-the-head are often worn away or
burst out long before the picker is worn out. To overcome these defects I press by
ordinary means a solid semi-circular or other conveniently shaped hoop or boss
round the above named parts on the picker in an embossed form which rises above
the face of the picker, giving greater additional strength to the same, thereby
enabling the picker to more firmly resist the action of the shuttle tip and spindle.
Round the outside of the holes in the picker head which slides on the spindle
similar embossed hoops or bosses are provided, thereby increasing the bearing or
sliding surface as well as strengthening the striking part which operates against
the stoppers.
I further strengthen the pickers by forming suitable embossed, corrugated, or
semi-circular bands or ridges between the embossed hoops or bosses round the part
where the shuttle tip strikes and those round the spindle holes in the picker head.
In some cases where necessary I continue the aforesaid band or ridges round other
portions of the picker, such as, to the top side of the head on each side or other-
wise, thereby increasing the strength of the sides and ends of the pickers, which
prevents them from bursting with the strain to which they are subjected.
In applying my improvements to the stoppers placed on the picker spindles and
against which the pickers strike, I form the embossed hoops or bosses round the
holes on the spindle, thereby increasing the strength of the part struck which
prolongs their existance, as well as that of the pickers.
In order that my invention may be fully understood and readily carried into
operation, I will proceed to describe the annexed sheet of drawings, reference being
made to the figures and letters marked thereon.
Fig. 1 is a front elevation of a single box picker employed in "overpicked"
looms; Fig. 2 is a side view of the same; A is the picker; B the spindle on which
it slides; the leg of the picker where the shuttle tip strikes is provided with the
hoop or boss C, which rises above the face of the picker, giving additional strength
to the same, thereby enabling the picker to resist the tip of the shuttle from
bursting open that part. The cap or head of the picker is provided with the
bosses D round the holes which admit or slide on the spindle B, by which the
wearing or bearing surface is considerably increased, thus strengthening these
parts against wear and tear, which also materially aids the picker in checking the
blow against the stopper. The pickers A are further strengthened on the ends by
the bands or ridges E extending from the boss or hoop C round the part where
the shuttle tip strikes to the boss or hoop D round the holes for admitting the

page_text: spindle B. In some cases where necessary the bands or ridges E are carried up
and round the head or cap of the picker A as in Figs. 3 and 4. In another
arrangement I construct the hoop or boss C round the part where the shuttle tip
strikes in an oval form as in Fig. 5, thus giving more space for the action of the
shuttle tip.
Fig. 6 is an elevation of a single box picker for "underpicked" looms; the end
where the shuttle tip strikes is provided with the hoop or boss C, which is shewn
more clearly in Fig. 8, which is an end view of the picker. The opposite end of
the picker is strengthened by the corrugations F, of which Fig. 7 is an end view.
In another arrangement I construct the sides of the picker with the corrugations F',
as in Figs. 9 and 10, which give additional strength to those parts; Fig. 11 being
an end view where the shuttle tip strikes.
Fig. 12 is an end view of a double box picker; the outside of the spindle
holes G being strengthened with the bosses or hoops D as before described; the
part struck by the shuttle tip being provided with the boss or hoop C.
Fig. 13 is a plan of Fig. 12.
Figs. 14 and 10 are side elevations of the stoppers H, Figs. 15 and 17 being end
views of the same respectively; the holes G which fit on the spindles B are
provided with the bosses or hoops D, against which the bosses or boops D on the
pickers A strike by the action of the shuttle, thus giving additional strength as
well as bearing surface, which also gives additional cushioning power to resist the
action of the shuttle on the picker.
The whole of these improvements are performed in the usual way by dies
specially prepared to form the bosses, ridges, and corrugations, as desired, being
made of any suitable material as before described.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim is
1st Constructing pickers, employed in "overpicked" and "underpicked" looms,
with the embossed parts C and D, and the ridges E, for the purposes described, and
as shewn on the drawings, or any mere modification or imitation thereof.
2nd Constructing pickers for "underpicked " looms with the corrugations F, for
the purpose described and as shewn on the drawings in Figs. 6, 7, 9, and 10.
3rd Constructing the stoppers H with the bosses D for the purpose described
and as shewn on the drawings in Figs. 14, 15, 16, and 17.
