PROVISIONAL SPECIFICATION left by the said James Harrop at the
Office of the Commissioners of Patents, with his Petition, on the
28th March 1873.
I, JAMES HARROP, of Manchester, in the County of Lancaster, Mill-
wright, do hereby declare the nature of the said Invention for "IMPROVE.
MENTS IN MACHINERY OR APPARATUS FOR THE MANUFACTURE OF WHAT IS COMMONLY
CALLED INDIA-RUBBER HOSE AND INDIA-RUBBER PIPING AND OTHER TUBULAR
ARTICLES COMPOSED OF SIMILAR MATERIALS," to be as follows:-

For this purpose I use

page_text: a table provided with a projecting guard or fence, against which is
placed the core of the intended article, such core consisting, by pre-
ference for hose, of a rope threaded through an india-rubber tube, and
beneath this core one edge of the "ply" to be coiled is placed. Above
the core are two rollers capable of being turned upward or downward
upon a longitudinal shaft driven by the motive power, and carrying
gearing which gives motion to screws connected to the bearings of the
aforesaid rollers, which are also caused to revolve by suitable gearing.
The core and ply having been adapted as above mentioned, the two
rollers are turned down so as to be brought in contact with the former,
the guard or fence giving way against springs, and the machine being
then put in motion, the two rollers by their rotation coil the "ply"
upon the core, and at the same time move outward bodily to effect the
necessary number of coils. This outward movement may extend to any
distance after the whole of the "ply" has been coiled to effect a rolling
action, after which the motion of the machine is reversed and a rolling
inward takes place. The usual application of naptha or similar material
is of course adopted.
The above description has special reference to india-rubber hose, but
the operation will be the same for india-rubber piping and other tubular
articles of similar materials, such as buffers, made either separately or in
SPECIFICATION filed in pursuance of the conditions of the Letters
Patent, and of an Order of the Lord Chancellor, by the said James
Harrop in the Great Seal Patent Office on the 11th October 1873.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
HARROP, of Manchester, in the County of Lancaster, Millwright, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-eighth day of March in the year of our a
Lord One thousand eight hundred and seventy-three, in the thirty-seventh
year of Her reign, did, for Herself, Her heirs and successors, give and
grant unto me, the said James Harrop, Her special license, that I, the said
James Harrop, my executors, administrators, and assigns, or such others
as I, the said James Harrop, my executors, administrators, and assigns 3
should at any time agree with, and no others, from time to time and at

page_text: 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 "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR THE MANU-
FACTURE OF WHAT IS COMMONLY CALLED INDIA-RUBBER HOSE OR PIPING AND OTHER
TUBULAR ARTICLES COMPOSED OF SIMILAR MATERIALS," upon the condition,
amongst others, that I, the said James Harrop, by an instrument in
writing under my hand and seal, 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 on or before the Fourteenth day of October One
thousand eight hundred and seventy-three.
NOW KNOW YE, that I, the said James Harrop do hereby declare
the nature of my said Invention, and in what manner the same is to
be performed, to be particularly described and ascertained in and by the
following statement and accompanying Drawings, that is to say:
"
"
My Invention relates to a method of coiling india-rubber or several
plies upon each other, and subsequently submitting them to a
rolling action.
In the accompanying Drawing, Fig. 1 shews the arrangement I use
in plan view, Fig. 2 is a cross section of the same, and Fig. 3 and 4,
side and end views of parts which will hereafter be referred to; Fig. 5
is a view of certain parts which may be considered a portion of Fig. 2,
as will presently appear.
At 1 is a table similar to that which is employed in the ordinary
manufacture of india-rubber hose or piping when a sheet or sheets of
the material are coiled upon a mandril, and which table, as is well known,
is extended so as to carry the desired length of the article to be produced.
In the Drawing, this table together with certain parts which it carries is
shewn broken off, as it would be of too great length to be drawn entire,
but the intermediate parts are mere repetitions. Upon the table 1 is
mounted the main shaft 2, upon which there are two loose pullies 3, 4,
and one fast pulley 5. From the loose pullies 3, 4, (according to the
positions shewn) are two straps 6, 7, driven by an overhead or other line
shaft, but one of these (say that shewn at 6) is open and the other
crossed, by which arrangement therefore they drive in contrary directions.
These straps are embraced by forks 8, 9, attached to a bar 10, which by

page_text: being slidden in the one direction or the other, is capable of placing
either of the straps 6, 9, on to the fast pulley 5. Upon the shaft 2 are
worms 11, 11*, in gear with wheels 12, 12*, the bosses of which are
provided with nuts, in which are situate screws 13, 13*, the said wheels
12, 12*, and their nuts being in brackets 14, 14*, which are capable of
swivelling upon the said shaft. On ends of the screws 13, 13*, are brackets
15, 15*, which carry two rollers 16, 17, free to revolve therein, and to
the upper ends of the said brackets are jointed rods 18, 18*, terminating
in chains which are attached to pullies 19 (see Fig. 5) carried by
brackets 20 which may be supposed as fixed to the roofing of the building.
Upon the axes of the pullies 19 is a worm wheel 21, taking into a
worm 22, the axis of which is provided with a pulley handle 23, and by
turning which therefore the rollers 16, 17, may be elevated or depressed.
Upon the main shaft 2 is a worm taking into a worm wheel 25, carried
by a bracket 26, which swivels on the shaft 2, the said worm wheel
being provided with a key situate within a groove formed in a shaft 27,
which shaft at its end is supported by a frame 28, which also carries the
two rollers 16, 17, and is provided with a worm 29, taking into a worm
wheel 30, carried by a short shaft 31. On this shaft 31 is a spur pinion
32 in gear with two pinions 33, 34, mounted respectively on the two
rollers 16, 17, when therefore motion is communicated to the main
shaft 2 the shaft 27 is also caused to revolve and communicate rotatory
motion through the medium of the gearing 29, 30, 32, 33, 34, to the
rollers 16, 17, and so as to cause them to rotate in the same directions,
but as the said shaft 27 is driven through the medium of a key and
slot it is free while driving the rollers 16, 17, as above referred to to
slide inward and outward within the worm wheel 25. In the table 1 is
a slit within which is placed a strip of wood 35, extending the whole
length of the said table and born upward by springs 36, situate at
interval within a casing 37.
The operation of the machine is as follows:-The attendant first places
the core of the intended article upon the table 1 against the fence 35,
such core being of any usual construction, such as a tube of india-rubber
with a cord threaded through it, then the material intended to form the
'plios" is placed upon the table, its inward edge being beneath the
core, and the usual application of naptha or similar material having been
made, the pulley handle 23 is turned so as to lower the rollers 16, 17,
on to the core which will then be situate between them. The strap
"

page_text: (say 7) is now moved from the loose on to the fast pulley 5, whereby
the main shaft 2 will be driven and by means of the worm and worm
wheel 25 will cause the shaft 27 to revolve, and this by means of the
gearing above described will impart rotatory motion to the rollers 16, 17,
both of them revolving in the same direction. At the same time the
worm 11 by driving the worm wheels 12, 12*, which as before stated
are provided with nuts in their bosses will cause the screws 13, 13*, to
traverse outward carrying with them the rollers 16, 17, by these double
movements therefore the core is caused to revolve and coil the material
spread upon the table thereon, while at the same time it is moved
bodily outward as the coils are made.
The whole of the material having been rolled upon the core, the
strap 7 may be removed from the fast pulley 5 and the other strap 6
placed thereon, by which means the whole of the gearing above described
becomes reversed, the rollers 16, 17, are driven in the contrary direction to
that above assumed, and the screws 13, 13*, also in like manner changed
in motion, by which means the finished article will be rolled back to
the fence 35, and will become consolidated by that operation, after
which it may again if desired be rolled outward and inward. This con-
solidation may, however, be effected by continuing the outward motion
of the rollers 16, 17, upon the table 1, after the whole of the material
has been coiled, if the said table be sufficiently wide.
In cases where it is desired to coil a greater width of material than
the table will hold, a portion thereof may be coiled as above described,
and the rollers, 16, 17, having been raised by turning the pulley handle
23, may be run back to the position shewn, and the partly finished
article having been moved to the fence 35, the same operations to those
above described may be repeated. The fence 35 is formed with an
incline on its upper part for the purpose of allowing the rollers 16, 17,
to depress it, should they be allowed to traverse too far inward. The
above described machinery may be used for the manufacture of what is
commonly called india-rubber hose or piping or similar tubular articles
composed of the like materials, such as buffers, either separately or in
longer lengths, to be subsequently cut up. The Drawing shews only two
screws 13, 13*, but more may be adapted at intervals along the rollers.
16, 17, and the left hand end of the said rollers may be geared up as
described in reference to the right hand end. The weight upon the hose
may be regulated by balance weights applied to the rollers 16, 17.

page_text: Having thus described the nature of my said Invention, and the manner
in which the same is to be performed, I desire it to be understood that I
claim as secured to me under the above in part recited Letters Patent,
and for the aforesaid purposes, the use of the rollers illustrated at 16, 17,
having a bodily as well as a rotatory motion imparted to them,
substantially as described.
In witness whereof, I, the said James Harrop, have hereunto set
my hand and seal, this Twenty-seventh day of September, in the
year of our Lord One thousand eight hundred and seventy-three.
JAMES HARROP. (L.S.)
