page_text: LETTERS PATENT to Joseph Holding of Lower Broughton in the County of
Lancaster Engineer for an Invention of " IMPROVEMENTS IN PICKERS AND
IN THE PARTS UPON WHICH THEY SLIDE AND IN THE METHOD OF AND MEANS
FOR CHECKING DICKEng"
PROVISIONAL SPECIFICATION left by the said Joseph Holding at the
Office of the Commissioners of Patents on the 13th July 1883.
JOSEPH HOLDING of Lower Broughton in the County of Lancaster, Engineer
*IMPROVEMENTS IN PICKERS AND IN THE PARTS UPON WHICH THEY SLIDE AND
IN THE METHOD OF AND MEANS FOR CHECKING PICKERS
•
My Invention relates in the first place to the pickers employed in looms for
weaving and has for its object to prevent the shuttle from flying out of the race.
In the pressing of the picker or at any suitable time I force a conical ended die
into the face of the picker so as to form a smooth 'recess to receive the shuttle tip
whereby the necessity for the cutting out of such recess is obviated and the picker
is rendered more durable. I may so form the said recess as that the shuttle tip is
raised when entering the recess. The effect of this is that when the shuttle is
driven out of the box the other end of the shuttle is depressed whereby the
tendency for the shuttle to fly out" is lessened. To effect the same object I may
form the shuttle with a projecting foot or with an inclined face.
In the second place to guide the shuttle I employ two rectangular or nearly
rectangular bars or channeled bars of cast iron. In some cases I may use steel or
wrought iron of flat, rectangular, "tee," "angle" or other suitable section. In the
manufacture of pickers to work on the said bars I mould or press a groove or
rectangular channel on each side of the picker or a channel suitable to the forms
of the said bars.
In the third place I dispense with the ordinary check strap and employ a hinged
weight or a lever or spring or a spring-lever to check each picker. In one case à
hinged lever with or without a spring is formed with an inclined or curved face
upon which the picker acts to raise the lever when driven to the end of the box
the shuttle being thereby checked. In other cases curved or bent springs are
substituted for levers.

"IMPROVEMENTS IN PICKERS AND IN THE PARTS UPON WHICH THEY SLIDE AND
IN THE METHOD OF AND MEANS FOR CHECKING PICKERS"
My Invention relates in the first place to the pickers employed in looms for
weaving and has for its object to prevent the shuttle from flying out of the race.
In the pressing of the picker or at any suitable time I force a conical ended die
into the face of the picker so as to form a smooth recess to receive the shuttle tip
whereby the necessity for the cutting out of such recess is obviated and the picker
is rendered more durable. I may so form the said recess as that the shuttle tip is
raised when entering.the recess. The effect of this is that when the shuttle is
driven out of the box the other end of the shuttle is depressed whereby the
tendency for the shuttle to fly out is lessened. To effect the same object I'may
form the shuttle with a projecting foot or with an inclined face.
In the second place to guide the picker I employ two rectangular or nearly
rectangular bars or channelled bars of cast iron. In some cases I may use steel
or wrought iron of flat rectangular "tee" angle or other suitable section. In the
manufacture of pickers to work on the said bars I mould or press a groove or
rectangular channel on each side of the picker or a channel suitable to the forms
of the said bars.
In order that my Invention may be fully understood I have attached hereunto
a sheet of drawings to which I will refer when describing my invention. In the
said drawings Fig 1 partly in section represents a front elevation and Fig 2
represents an end elevation of a picker formed in accordance with my invention.
In the said Figs a is the recess which I form in the face of the picker to receive
the tip of the shuttle. Fig 3 illustrates the means whereby the said recess is
formed. In this Fig b is the lower part of a picker shewn in section and c, c also
in section represent the parts of the dies which are employed to press the picker
into form. In one of these dies a hole is bored and in this hole a die d is fitted
to slide. The inner end of this die is made of a rounded form or of the form
which it is desired that the recess shall have. If preferred the end-of the said die
may be conical or it may be partly conical or partly conical and partly rounded or
be of any desired form. When the picker is being pressed the die d is forced
inwards by means of a lever or cam or by other suitable means so as to form the
said recess. If preferred the recess may be formed by an operation subsequent to
the ordinary pressing in dies a sliding die or punch being used in connection with
a die or part to hold the picker. A corresponding recess may be formed on each
face of the picker two dies sliding in opposite directions being employed or the
picker may be reversed for the formation of the second recess. Fig 6 illustrates a
formation of the recess designed to lessen the tendency of the shuttle to fly out of
the race.
The recess is so formed as that in entering the recess the tip of the
shuttle is slightly lifted. Fig 5 illustrates the manner in which I provide the
picker with a projecting foot to obtain the same effect. The foot e is either formed
from the material of the picker in the manufacture or pressing of the same or
is a separate piece of hide or metal or substance fixed to the lower end of the
picker.
:
The second part of my invention is illustrated by Fig 4 which is a perspective,
view of a picker adapted to slide upon and between two bars. The picker is formed

page_text: with channels at each side these channels being made of a form to suit the bars ff
which in the example are rectangular in cross section the channels therefore being
flat bottomed. prefer to form the channels by pressure the dies being adapted
to impart the required forin without any cutting away of the material to form the
channels. The channel or channels on one side of the picker are indicated at g, g
in Fig 5
Having now fully set forth and indicated the nature of my said invention I
would have it to be understood that I claim :
First. The picker formed with a recess on the face or on each face by pressing
a suitably formed die into the substance of the picker substantially as set forth
and indicated herein before and in and by the accompanying drawings.
Secondly. Forming a recess in the face or in each face of a picker by the
means substantially as set forth and indicated with reference to Fig 3 of the
drawings.
Thirdly. A picker with a projecting foot e for the purpose set forth and
indicated.
And lastly. Providing two bars for the picker to slide upon and forming the
picker with side channels or grooves to suit the said bars substantially as set forth
and indicated.
In witness whereof I the said Joseph Holding have hereunto set my hand and
seal the eleventh day of January in the year of our Lord One thousand eight
hundred and eighty four.
