Year: 1862

page_text: LETTERS PATENT to William Harrison and John Harrison, both of the
Firm of Messieurs J. Harrison and Sons, of Blackburn, in the
County of Lancaster, Machine Makers, and John Oddie and William
Parkinson, Foremen in the Employ of the above J. Harrison and Sons,
for the Invention of "CERTAIN IMPROVEMENTS IN MACHINERY FOR WINDING,
SIZING, AND WEAVING."
Sealed the 11th November 1862, and dated the 26th May 1862.
PROVISIONAL SPECIFICATION left by the said William Harrison, John
Harrison, John Oddie and William Parkinson at the Office of the
Commissioners of Patents, with their Petition, on the 26th May
1862.
We, WILLIAM HARRISON and JOHN HARRISON, both of the Firm of
Messieurs J. Harrison and Sons, of Blackburn, in the County of Lancaster,
Machine Makers, and JOHN ODDIE and WILLIAM PARKINSON, Foremen in
the Employ of the above J. Harrison and Sons, do hereby declare the nature
of the said Invention for "IMPROVEMENTS IN MACHINERY FOR WINDING, SIZING,
AND WEAVING," to be as follows:-
Our improvement in winding machines consists in an improved mode
of constructing the rails for the bearings of the spindles. We cast the throstle
rail with two ribs; in the lower rib the foot steps of the spindles are drilled,
and to the upper rib the bearings or bolsters for the spindles are secured.
By this arrangement the construction is simplified and the loose covers
now required are dispensed with.
Our improvement in machinery for sizing consists in supporting the end

page_text: of the cone shaft in a swivel bearing acted upon by a lever for throwing the
pinion on the cone shaft in or out of gear with the wheel to be driven.
Our improvements in machinery for weaving consist, first, in applying a
regulating screw to the bearing of the tappet shaft for regulating the depth of
gear of the wheels.
Secondly, in connecting the picking tappet to the tappet shaft by means of
a bush fixed to the shaft, on which bush and on the picking tappet teeth are
cast; by this means the picking tappet is securely held and its position can be
easily regulated.
Thirdly, in applying a catch to the incline which passes through a slot in
the breast beam and serves as a stop to the lever supporting the weft fork
for applying the break to the fly wheel when the weft motion acts.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Harrison, John Harrison, John Oddie, and William
Parkinson in the Great Seal Patent Office on the 26th November
1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, WILLIAM
HARRISON and JOHN HARRISON, both of the Firm of Messieurs J. Harrison
and Sons, of Blackburn, in the County of Lancaster, Machine Makers, and
JOHN ODDIE and WILLIAM PARKINSON, Foremen in the Employ of the above
J. Harrison and Sons, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-sixth day of May, in the year of our Lord
One thousand eight hundred and sixty-two, in the twenty-fifth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto s
us, the said William Harrison, John Harrison, John Oddie, and William
Parkinson, Her special license that we, the said William Harrison, John
Harrison, John Oddie, and William Parkinson, our executors, administrators,
and assigns, or such others as we, the said William Harrison, John Harrison,
John Oddie, and William Parkinson, our executors, administrators, and
assigns, should at any time agree with, and no others, from time, to
time and at all times thereafter during the term therein expressed, should
and lawfully might make, use, exercise, and vend, within the United
Kingdom of Great Britain and Ireland, the Channel Islands, and Isle of
Man, an Invention for "CERTAIN IMPROVEMENTS IN MACHINERY FOR WINDING, S
SIZING, AND WEAVING," upon the condition (amongst others) that we, the said

page_text: William Harrison, John Harrison, John Oddie, and William Parkinson,
our executors or administrators, by an instrument in writing under our,
or their, or one of our or their hands and seals, should particularly describe
and ascertain the nature of the said Invention, and in what manner the same
was to be performed, and cause the same to be filed in the Great Seal Patent
Office within six calendar months next and immediately.after the date of the
said Letters Patent.
NOW KNOW YE, that we, the said William Harrison, John Harrison;
John Oddie, and William Parkinson, do hereby declare the nature of our
said Invention, and in what manner the same is to be performed, to be par-
ticularly described and ascertained in and by the following statement, that is to
say:
Our improvement in winding machines consists in an improved. mode of
constructing the rails for the bearings of the spindles.
Our improvement in machinery for sizing consists in supporting the end
of the cone shaft in a swivel bearing acted upon by a lever for throwing the
pinion on the cone shaft, in or out of gear with the wheel to be driven.
Our improvements in machinery for weaving consists, first, in applying a
regulating screw to the bearing of the tappet shaft for relguating the depth of
gear of the wheels.
Secondly, in connecting the picking tappet to the tappet shaft by means
of a bush fixed to the shaft, on which bush and on the picking tappet teeth
are cast; by this means the picking tappet is securely held, and its position can
be easily regulated.
.
Thirdly, in applying a catch to the incline which passes through a slot
in the breast beam and serves as a stop to the lever supporting the weft fork,
for applying the break to the fly wheel when the weft motion acts.
And in order that our Invention may be fully understood and readily carried
into effect, we will proceed to describe the accompanying Sheet of. Drawings,.
reference being had to the figures and letters marked thereon:
Fig. 1 represents an elevation of the end of a winding machine; a, a, are
the spindles revolving in bearings in the top or bolster rail b, shewn in
section on an enlarged scale in Fig. 2, and partly in plan on Fig. 3. The
lower ends of the spindles a revolve in adjustable footsteps in the bottom or
spindle rail c, shewn in section in Fig. 4, and partly in plan in Fig. 5. The
rail c is cast with projections which are bored out to receive the footsteps d,'
in which the ends of the spindles revolve; the footsteps are held in their places
by the set screws e, and the regulating screws fact on the under side of the
footsteps to set them up when the. footstep or the end of the spindle is worn away

page_text: Fig. 6 is a section of our improved rails for the bearings of the spindles of
winding machines. The throstle rail is cast with two ribs marked b and c;
in the lower rib c the footsteps of the spindles are drilled, and to the upper rib
6 the bearing or bolsters b', in which the spindles revolve, are secured by. a
bolt in such wise that the bearing or bolster b₁ can be adjusted to
the footstep. By this means the construction of the rails of winding
machines is simplified, and the loose covers now required to close the
space between the two rails are dispensed with. Fig. 8 represents
part of a sizing machine of the usual construction to which our improve-
ments are applied; g is the cone shaft, one end of which is supported by the
bearing h, which is acted upon by the horizontal arm i of the elbow lever i'.
When the elbow lever is in the position shewn by the full lines. in Fig. 8,
the pinion on the cone shaft is in gear with the wheel J by which it is
driven; but when it is requisite to throw the wheels out of gear the. upper
end of the lever ¹, is disengaged from the retaining notch, and the lever
then assumes the position indicated by dotted lines, thus lowering the end of
the cone shaft g.
Our improvements in looms for weaving are illustrated by the Figs. 9,
to 14. Fig. 9 is an end view, and Fig. 10. part of a front view of a loom
to which the first of our improvements in looms is applied; k is the crank
shaft and the tappet shaft which revolves in the adjustable bearing ; to this
bearing is fixed a screw passing through a bracket cast or fixed to the
loom side, the screw has a lock nut above and below the bracket, and by
means of these lock nuts and the screw the depth of gear of the wheels k¹
and 13 can be regulated so as to keep the wheels 13 and k' always in proper
gear, thus preserving the teeth of the wheels when the loom is picking.
Fig. 11 is a detached view of the picking tappet m, and Fig. 12 is a
detached view of the bush n by which the picking tappet is connected to the
tappet shaft 7. The bush n is keyed on the tappet shaft ; this bush and the
picking tappet m, which is loose on the shaft, are cast with teeth fitting.
into each other, when the tappet and bush are bolted together, as shewn
in Fig. 10. The position of the picking tappet can be regulated with great
accuracy by this improved mode of connecting the tappet to the shaft, and.
when the tappet is in its true position it is securely and firmly held by the
contact of the toothed surfaces and by the bolts. Fig. 13 is an end view of a s
loom, and Fig. 14 part of a front view of the same, to which the third of our
improvements in looms is applied; k is the crank shaft; o is the break acting
as usual on the break or fly wheel ; p is the frog connected to the break o
by the side bar p; under the side bar p' is a weighted elbow lever p², con-

page_text: nected by the link p to the lever with the incline p*; q is the spring
starting lever connected to the frog p by a screw and nuts q¹, and furnished
with a projection q' acting on the incline p'; r is the breast beam and s
the lever supporting the weft fork; these parts are made in the usual manner.
excepting that the lever with the incline p* is made with a catch p', passing
through a slot in the breast beam r, which catch serves as a stop for the lever s.
The mode of operation is as follows:-When the weft motion acts, the
lever s being pushed forward in the usual manner liberates the catch p³; the
weighted end of the elbow lever på then drops and applies the break o to the fly
wheel when the spring starting lever q, is being replaced into its proper
position for again starting the loom, the projection q³, acting on the incline
p', raises the catch 2 into its former position for holding the weft fork
lever s.
Having thus stated the nature of our Invention and described the manner of
performing the same, we declare that we claim,—
First, the improved mode of constructing the rails of the spindles of winding
machines, as shewn and described in reference to Figs. 6 and 7.
Secondly, the use of a swivel bearing for supporting the end of the cone
shaft of winding machines, and the application of a lever for throwing the pinion
on the cone shaft in and out of gear with the wheel to be driven, as shewn and
described in reference to Fig. 8.
Thirdly, the application of a regulating screw to the bearings of the
tappet shafts of looms, as shewn and described in reference to Figs. 9
and 10.
Fourthly, the improved mode of connecting the picking tappet to the
tappet shaft of the loom, as shewn and described in reference to Figs. 10,
11 and 12.
And, lastly, the application of the catch marked p³s to the lever with the
incline p', in the manner and for the purpose described in reference to Figs. 13
and 14.
In witness whereof, I, the said John Harrison, have hereunto set my
hand and seal, this Twenty-fifth day of November, in the year of our
Lord One thousand eight hundred and sixty-two.
JOHN HARRISON. (L.s.)
