IMPROVEMENTS IN THE CONSTRUCTION OF SHUTTLES USED IN LOOMS FOR WEAVING
Year: 1882

page_text: LETTERS PATENT to John Rawlinson Richards, of Kirkham, near Preston, in
the County of Lancaster, for an Invention of "IMPROVEMENTS IN THE
CONSTRUCTION OF SHUTTLES USED IN LOOMS FOR WEAVING."
PROVISIONAL SPECIFICATION left by the said John Rawlinson Richards at
the Office of the Commissioners of Patents on the 25th January 1882.
JOHN RAWLINSON RICHARDS of Kirkham near Preston in the County of
Lancaster." IMPROVEMENTS IN THE CONSTRUCTION OF SHUTTLES USED IN LOOMS
FOR WEAVING."
My Invention relates to the construction of the tongue or peg of the shuttle,
the object of the Invention being to close the spring of the peg as the latter is
raised up out of the shuttle, so that the cop pirn or bobbin of weft can be easily
placed thereon or removed therefrom, and thus to diminish the liability to injury
to the interior thereof and consequent waste of the yarn. As tho peg with the cop
pirn or bobbin on it, is pressed back into the shuttle the spring expands, and holds
the cop pirn or bobbin fast.
According to one modification of my Invention I fix a double excentric or cam
in the slot at the heel end of the peg, and between this excentric and the end of
the spring of the peg passes a bent arm which is capable of oscillating on a pin
fixed in the wood of the shuttle. The form of this bent arm and of the double
excentric or cam fixed in the peg, is such that as the shuttle peg is turned outwards
from the shuttle the spring of the peg is closed in and the cop can be easily placed
thereon or removed but as the peg is pressed back into the shuttle the spring
expands and holds the cop pirn or bobbin of weft securely on the peg.
I sometimes make the bent arm double so that it will give more or less prossure
according to the power required.
In another modification of my Invention instead of having an excentric or cam
fixed in the heel end of the peg and turning with it I fix a somewhat similar
excentric by pins firmly in the wood of the shuttle, the peg of which is made with a
slot at the heel which works freely over the fixed excentric. The working surface
of the latter (against which the end of the peg spring acts) instead of being solid,
is made in the form of a spring, and the bent arm is dispensed with. This spring
portion of the excentric, acting against the end of the peg spring, not only expands
the latter when the peg is pressed into the shuttle, but at the same time counteracts
all tendency of the peg to fly up when the cop or pirn is in its place, and prevents
any oscillation of the same when working.

the said John Rawlinson Richards in the Great Seal Patent Office on the
24th July 1882.
JOHN RAWLINSON RICHARDS of Kirkham near Preston in the County of
Lancaster. "IMPROVEMENTS IN THE CONSTRUCTION OF SHUTTLES USED IN LOOMS
FOR WEAVING.”
My Invention relates to the construction of the tongue or peg of the shuttle the
object of the Invention being to allow the spring of the peg to close as the latter is
mised up out of the shuttle, so that the cop pirn or bobbin of weft can be easily
placed thereon or removed therefrom, and thus to diminish the liability of injury 1
to the interior thereof and consequent waste of the yarn. As the peg, with the cop
pirn or bobbin on it is pressed back into the shuttle the spring expands, and holds
the cop pirn or bobbin fast.
Such being the nature and object of my said Invention I will now proceed to
describe in detail the manner in which the same is to be or may be performed or 1
carried into practical effect and in order that the same may be clearly understood.
I have annexed hereunto a Sheet of Drawings illustrative thereof and have marked
the same with figures and letters of reference corresponding with those in the
following explanation thereof.
-According-to-one-modification_of_my_Invention illustrated by Figs. 1, 2, and 32
on the annexed Drawing I fix an excentric or cama, a in a slot-at-the-heel-end
of the peg b, b (see also plan view of peg Fig. 2) and between this excentric and
the end of the spring c, e of the peg passes a bent arm d, d which is capable of
oscillating on a pin e fixed on the wood of the shuttle.
The form of this bent arm d; d and of the excentric or cam a, a fixed in the peg, 2
is such that as the shuttle peg b, b is turned outwards from the shuttle (see Fig. 3)
the spring c; c of the peg is allowed to close in and the cop can be easily placed
thereon or removed but as the peg b, b is pressed back into the shuttle the spring c, c
is expanded by the bent arm d, d as shown at Fig. 1. and holds the cop pirn or
bobbin of weft securely on the peg.
I sometimes make the bent arni double so that it will give more or less pressure
according to the power required (see Fig. 2*).
In another modification of my Invention shown at Figs. 4 and 5 instead of
having an excentric or cam fixed in the heel end of the peg and turning with it I
fix a somewhat similar excentric f; f by pins firmly in the wood of the shuttle, the 3
peg b, b of which is made with a slot in the heel which works freely over the fixed
excentric, as in Fig. 2. The working surface of the latter (against which the
end of the peg spring c, c acts) instead of being solid, is made in the form of a
spring g, g and the bent arm d, d is dispensed with.
This spring portion g, g of the excentric ff acting against the end of the peg 4
spring c, c uot only expands the latter when the peg is pressed into the shuttle (see
Fig. 4.) but at the same time counteracts all tendency of the peg b, b to fly up when
the cop or pirn is in its place in the shuttle and prevents any oscillation of the same
when working.
In a further modification of my Invention shown at Figs. and 7. instead of 4
fixing the excentric (which acts against the heel end of the peg spring substantially
as described in the previous modification) in the shuttle firmly by pins I make it a
part of, or a combination of the ordinary shuttle spring h, h which acts against the
heel of the peg b, b.
In this case the one spring serves for two purposes,; vízt., to hold the peg in §

page_text: either the open or closed position, and secondly to allow the peg spring to close
when the peg is raised to remove or replace the pirn or cop.
Having now described the nature and object of my said Invention together with
the manner in which the same is to be or may be performed or carried into practical
effect I wish it to be understood that I claim as my Invention
First the construction of a shuttle peg with an excentric or cam fixed in a slot
at its heel and acting by means of a bent arm (fixed in the wood of the shuttle)
upon the end of the peg spring in such a manner as to expand the latter when the
peg is closed in the shuttle, and to allow it to close as the peg is raised up
substantially as illustrated by Figs. 1. 2 and 3. of the annexed Drawings and
hereinbefore described.
•
Secondly I claim a similar excentric or cam fixed in the wood of the shuttle and
provided with a curved spring piece to act upon the peg spring in the manner
described and illustrated by Figs. 4 and 5 of the annexed Drawing and
Thirdly I claim a similar spring piece or cam forming a portion or continuation
of the ordinary shuttle spring and acting upon the end of the peg spring substan-
tially as herein before described with reference to Figs. 6 and 7 of the annexed
Drawing.
In witness whereof I the said John Rawlinson Richards have hereunto set
my hand and seal this Twenty first day of July in the year of our Lord
One thousand eight hundred and eighty two.
