Year: 1873

page_text: LETTERS PATENT to Georgo Pomeray Dodge, of Upper Thames Street,
in the City of London, for the Invention of "IMPROVEMENTS IN
HOSE PIPES."-A communication from abroad by Gordon McKay, of
Boston, Massachusetts, United States of America.
Scaled the 13th May 1878, and dated the 11th March 1878.
PROVISIONAL SPECIFICATION left by the said George Pomeray Dodge
at the Office of the Commissioners of Patents, with his Petition,
on the 11th March 1873.
I, GEORGE POMERAY DODGE, of Upper Thames Street, in the City
of London, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN HOSE PIPES," a communication to me from abroad by
Gordon McKay, of Boston, Massachusetts, United States of America, to
bo as follows:-
This Invention relates to hose pipes of canvass or other suitable
material, coated on either or both surfaces with india-rubber or other
suitable composition, with a view to rendering the material more impor-
vious to air, gas, or liquid, or even made entirely uncoated, or of leather,

page_text: and consists of a novel and peculiar mode or method of forming the
seam or junction, which is effected by means of a stitching or sewing
machino constructed for the purpose. The said scam or junction is to be
overlapped, and reinforced or not, by having a strip of the material
stitched over and along the junction either inside or outside the hose, or 5
both insido and outsido, or the junction edges may be made to fold back
one over or under the other, so that the stitches or other fastenings shall
pass through more than two thicknessos, and shall in all cases be intro-
duced in a direction which is radial to the hose.
By this Invention greater economy in the cost of manufacture is 1
insured whilst greater facility is afforded for the manufacture of
internally coated lose than when the hose is woven in the form of a
cylinder, or wrapped or stuck together as in ordinary rubber hose, as
according to this Invention the material may be coated on one or both
faces before it is cut up into the strips which are afterwards formed into 1
hoso by the method of stitching or fastening the edges of such strips
herein-boforo set forth.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said George Pomoray Dodge in the Great Scal Patent
Office on the 10th September 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
POMERAY DODGE, of Upper Thames Street, in the City of London, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eleventh day of March, in the year of 2
our Lord One thousand eight hundred and seventy-three, in the thirty-
sixth year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said George Pomeray Dodge, Her special license
that I, the said George Pomeray Dodge, my exccutors, administrators,
and assigns, or such others as I, the said George Pomeray Dodge, a
my 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

page_text: and Ireland, the Channel Islands, and Isle of Man, an Invention for
“IMPROVEMENTS IN HOSE PIPES," a communication to me from abroad by
Gordon McKay, of Boston, Massachusetts, United States of America,
upon the condition (amongst others) that I, the said Georgo Pomeray
Dodge, my executors or administrators, by an instrument in writing under
my, or their, or one of their hands and seals, should particularly describe
and ascertain the nature of the said Invention, and in what manner
the same was to bo performed, and cause the same to be filed in the
Great Seal Patent Office within six calendar months next and imme-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said George Pomeray Dodge, do hereby
declare the nature of the said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained
in and by the following statement thereof, that is to say :—
This Invention relates to hose pipes of canvas or other suitable
material, coated on either or both surfaces with india-rubber or other
suitable composition, with a view to rendering the material more imper-
vious to air, gas, or liquid, or even made entirely uncoated or of leather,
and consists of a novel and peculiar mole or method of forming the
seam or junction, which is effected by means of a stitching or sewing
machine constructed for the purpose. The said seam or junction is to
be overlapped and reinforced or not by having a strip of the material
stitched over and along the junction, either inside or outside the hose, or
both inside and outside, or the junction edges may be made to fold back
one over or under the other, so that the stitches or other fastenings
shall pass through more than two thicknesses, and shall in all cases be
introduced in a direction which is radial to the hose.
By this Invention greater economy in the cost of manufacturo is
insured, whilst greater facility is afforded for the manufacture of internally
coated hose than when the hose is woven in the form of a cylinder, or
wrapped or stuck together as in ordinary rubber hose, as according to.
this Invention the material may be coated on one or both faces before it
is cut up into the strips, which are afterwards formed into hose by the
method of stitching or fastening the edges of such strips herein-before
set forth.

of sewed hose.
Figure 1 shews the machine in plan; Figure 2 is a front elevation of
it; Figure 3 is an end elevation; Figure 4 is a cross section of the arm
and guide on the line x, x; Figure 5 is a cross section of the arm
shewing the whorl in full size; Figure 6 is a section of the end of the
work-supporting arm, shewing the whorl in plan. a denotes a bed
plate, from which riso uprights 6, in which is journelled the driving
shaft c. The bed plate is mounted upon a 'suitable pillar or post d, and
upon one side of it it has an arm or extension e, to which is attached a
slide that carries the work-supporting arm g, in the front end of which
is the reciprocating or rotating whorl or thread guide h. From the
front upright 6 extend arms i, in which are the bearings for the verti-
cally reciprocating needle bar k and presser foot 2. The, needle mis a
hook needle, and has working in conjunction with it the ordinary hook :
needle cast-off extending from a bar n. The needle bar is connected by
a link o to an eccentric p on the shaft c, and the cast-off is operated by a
finger q extending from the needle bar and a spring r. The bars of the
presser foot is operated by a cam on the driving shaft (through the
intervention of a lever u) and a spring o, the cam t effecting the rise of
the presser foot, and the spring throwing it down, the presser foot being
at all times in contact with the work, except when raised by the cam
projection, at which rise the feed of the work is effected. The needle,
cast-off, presser foot, and thread guide perform their functions in the
formation of a stitch in the usual manner, the Invention so far as thoy 2
are concerned relating only to their arrangement.
'
When the hook of the needle has passed through the work and
entered the arm §, it passes through the eye or centre wo of the whorl,
and then the whorl is moved relatively to throw the thread running
through the thread eye around or partially around the needle shank, g
so that as the needle rises the thread will enter the hook, and be drawn
up with the needle.
The movement of the whorl is effected as follows:-Extending
through the arm is a slide bar y, having at one end gear teeth meshing
into teeth on the periphery of the whorl, this slide bar being jointed to
the foot of an arm a' extending from one end of a rocker shaft b³, at
whose opposite end is an arm c³ connected by a link d³ with a vertical
lever e³, from whose upper arm à pin extends into the groove of a cam

page_text: wheel on the driving shaft. The link is so jointed to the lever
armo as to disconnect therefrom by raising the link, such disconnection'
enabling the arm g to be drawn back for inspection of the whorl or
introduction of the thread, the thread running from the spool under the
5 arm through a holo g, and thence through the whorl, and out through.
the top of the arm. Under and around the arm g extends the work
guide. This guide is a long plate curved transversoly, and changing
in form from a shallow convex upper surface at its outer end to a
tubular form at its opposite end. Into its outer ond enters the and of the
0 strip to be formed into a hose, the opposite edges of such strip passing
under guide lips 3. As the strip passes through this guide it is
gradually and uniformly bent, and at the opposite end of the guido it
emerges bont into tubular form with one odge lapping the other, or
the end of the guide surrounding the arm g, and the lapped edges as
5 they emerge resting upon the arm, the end of the guide being close to
the eye or hole in the top of the arm through which the neodle enters.
Thus as the lapped edges emerge from the guide they are united by the
stitch-forming mechanism. At the end of the guide one edge of the
strip may abut against a shoulder formed on the guide, the other edgo
O lapping over it, and a short distance back the guide may have plates ³
made with internal guide lips for guiding the respective opposito edges
of the strip.
The work is brought to the action of the stitch-forming 'mechanism as
follows:-At one end of the bed plate are bearings for supporting two
5 shafts o³, p³, the bearings of the lower shaft p being stationary, and
those of the upper shaft movable. These shafts are geared together at
their rear end, and at their front ends are feed wheels q³, r". These
wheels are made as ratchet wheels, and the bottom wheel has direct
intermittent rotative movement imparted to it as follows:-Upon the
0 shaft p³ is hung a pawl lover &' having jointed to its vertical arm a
pawl which engages with the teeth of a ratchet wheel on the
shaft p. The other and horizontal arm of the lever has jointed to it a
vertical link u³ connected at its upper end to one arm of a lever v³, from
whoso other arm a pin extends into the groove of a cam wheel w³ on
5 the driving shaft e, the intermittent outward movement of the lever arm
by the cam imparting through its connections with the pawl the
intermittent forward or feed movements of the pawl and of the food
wheel with which the pawl engages. As the shafts aro geared together
7

page_text: the rotative movement of the lower shaft drives the upper one, so that
both feed wheels move together. The sewed tube is drawn through or
between these feed rolls in a flat or collapsed form, and by their action
they impart the requisito feed, such feed acting in conjunction with the
needle, whorl, &c., to form the continuous succession of stitches to form
the tube. As the stitches form a ridge upon the top of the sewed tube
the upper roll may be grooved, as seen at Figure 3, to receive such ridge.
The respective movements of the various parts of the mechanism are
timed so that when the needle descends the work is at rest, held by the
presser foot, the feed wheels being stationary, and after the needle has
risen the presser foot rises and releases the work, and the feed wheels
then rotate and effect the forward movement of the work. The guide ⁄ª
is attached to the machine by a pivot y, and for forming hose of
various sizes series of guides adapted to such sizes are used inter-
changeably.
The simplest form of the hose made from the woven strip, as
described, is shewn in Figure 7, the edges being lapped and then united
by a line of stitches passing from inside to outside, or vice versa.
In Figure 8 the lapping edges are bent so as to hook together, being
then united by the stitches passing from inside to outside, as shown..
In Figure 9 is shown the seam of a tube made by lapping the edges
and then uniting them by stitches passing through a fold made by
bending the lapped edges and stitching through from outside to out-
side.
In Figure 10 two such scams are shewn.
In Figure 11 there are two seams, one passing from inside to outside,
and the other from outside to outside.
In Figure 12 a welt piece is first stitched to one edge of the strip, and
the opposite edge of the strip is then inserted between the first edge and
the welt, the thrco being then united as shewn..
In Figure 18 is shown a seam made with the strip wrong side out,
the seam being made and the tube being then reversed or turned right
side out.

ment of mechanism for forming hose, and the hose made of a strip of
woven material, having its opposite edges united by a sowing machino,
substantially as described.
In witness whereof, I, the said George Pomorny Dodge, have here-
unto set my hand and scal, this Sixth day of September, in
the year of our Lord One thousand cight hundred and seventy-
throo.
