Year: 1883

page_text: LETTERS PATENT to John Richardson of the Hope Foundry Farnworth near
Bolton in the County of Lancaster Loom Maker and Iron Founder and Joy
Robinson of the same place Manager, for an Invention of "IMPROVEMENTS
IN THE PICKING MOTION FOR LOOMS."
"
"
PROVISIONAL SPECIFICATION left by the said John Richardson and Joy
Robinson at the Office of the Commissioners of Patents on the 10th October
1883.
JOHN RICHARDSON of the Hope Foundry, Farnworth, near Bolton in the County
of Lancaster Loom Maker and Iron Founder and JoY ROBINSON of the same place,
Manager IMPROVEMENTS IN THE "PICKING MOTION" FOR LOOMS."
"
The object of our Invention to make a simple picking motion" and to
dispense with the sliding tumbler, scroll half moon and the tumbler staples, secured
to the fly wheel
In performing our Invention we fix a striker upon each of the two fly wheels:
this striker acts on the ordinary tongue fixed to the picking shaft for striking the
shuttle
In order to hold the picking shaft out of action when the shuttle is at the other
side of the loom we fix an eccentric or tappet on the weft motion or other
convenient shaft which acts on a projecting part of the picking shaft at every
other revolution of the crank or loom and turns the picking shaft in its bearings
thereby allowing the striker to pass without hitting the tongue on the picking
shaft until the shuttle comes to this side of the loom. The picking shaft is brought
back to its normal position ready to be acted upon by the striker by the ordinary
check leathers or springs, or by its own weight.
Our improvements are applicable to under pick looms with one or more shuttles.

by the said John Richardson and Joy Robinson in the Patent Office on the
10th April 1884.
JOHN RICHARDSON, of the Hope Foundry, Farnworth, near Bolton, in the County
of Lancaster, Loom Maker and Iron Founder and JOY ROBINSON, of the same place,
Manager "IMPROVEMENTS IN THE PICKING MOTION' FOR LOOMS"
'
The object of our Invention is to make a simple picking motion' and to dispense
with the sliding tumbler, scroll, half moon, and the tumbler staples, secured to the
fly wheel.
In performing our Invention we fix a striker upon each of the two fly wheels:
this striker acts on the ordinary tongue fixed to the picking shaft to actuate the
picking stick for striking the shuttle
In order to hold the picking shaft out of action when the shuttle is at the
other side of the loom we fix an eccentric or tappet on the weft motion or other
convenient shaft which acts on a projecting part of the picking shaft at every
other revolution of the crank or loom and turns the picking shaft in its bearings
thereby allowing the striker to pass without hitting the tongue on the picking
shaft until the shuttle comes to this side of the loom. The picking shaft is brought
back to its normal position, ready to be acted upon by the striker, by the ordinary
check leathers, or springs, or by its own weight.
Our improvements are applicable to under pick looms with one or more shuttles.
And in order that our Invention may be fully understood and readily carried into
effect we will proceed to describe the accompanying Drawing which represents part
of a loom to which our Invention is applied.
a is the picking shaft fitted in suitable brackets secured to the loom frame: bis
the tongue which is struck by a striker on the fly-wheel c to give motion to the
picking stick d: on the picking shaft we fix or form an additional tongue e parallel
with the tongue b: We fix a tappet or cam f on the weft motion shaft that comes
in contact with and moves the tongue e at every second revolution of the crank
shaft and when the cam f moves the tongue e, it turns the picking shaft a partly
round so that the tongue b is moved out of the path of the striker on the fly
wheel c which is thus only allowed to act on the picking shaft at every other
revolution.
Having stated the nature of our Invention and described the manner of
performing the same
We declare that we claim
The picking shaft a provided with a projection or tongue e actuated by a cam f.
substantially as and for the purpose herein set forth.
In witness whereof I the said John Richardson for myself and on behalf of the
said Joy Robinson have hereunto set my hand and seal this ninth day of April
One thousand eight hundred and eighty four.
