PROVISIONAL SPECIFICATION.
New or Improved Apparatus for Manufacturing Material for
Preventing the Radiation or Transmission of Heat.
I JAMES CROFT SEWELL of the Firm of Sewell and Company of 24 River Street
Shiffball Street Bolton in the County of Lancaster, Composition Manufacturers do
hereby declare the nature of my said invention to be as follows
This invention relates to new or improved apparatus for manufacturing heat
non-conducting material for covering hot and cold water pipes, steam boilers, steam
pipes, hot air pipes, ice houses, refrigerators, gas stoves, chemical apparatus, and
the like, and consists of a machine whereby the same may be performed by hand or
power. This I carry into effect by constructing the machine of suitable frame
work of any convenient width and length to which is secured at one end fixings or
bearings to receive a roller containing woven wire of any suitable or required thickness
that will allow of wrapping or otherwise. The woven wire passes from the
aforesaid roller through a split roller to produce tension and on to a pole with pins
and a roller mounted on the other end of the machine. When the woven wire
is distended across the machine pads composed of silicate cotton or slag wool or
asbestos fibre are placed thereon and secured thereto by means of wires passed over
the same; the said wires being supplied from reels through needles bent to form a
shed and curve. The wires as they pass from the reels are delivered to hanging
pulleys provided with weights to form a yielding and uniform tension. The
needles are provided with grooves to receive the wires and are mounted in a frame
that can be handled by the operator to pass the same through the woven wire,
after which the same is secured by wire being drawn across underneath by a hook
and bent over on the upper side of the woven wire. The locking or under wire is
drawn or supplied from a reel or hobbin suitably mounted on the machine. The
tension of the wires is regulated by a yielding frame hung in any convenient
manner. In a power machine the wires are operated by shuttle.

New or Improved Apparatus for Manufacturing Material for
Preventing the Radiation or Transmission of Heat.
I, JAMES CROFT SEWELL, of the Firm of Sewell and Company, of 24, River
Street, Bolton, in the County of Lancaster, Composition Manufacturers, do hereby
declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement, that is to say :-
It relates to new or improved apparatus for manufacturing material to be used
as means for preventing the radiation or transmission of heat from hot and to cold
water-pipes, or from steam boilers, steam pipes, hot-air pipes, gas stoves, chemical
apparatus, or to ice houses, refrigerators and the like, and consists of a machine
whereby the same may be performed by hand or power, and in order that my said
Din, 7

page_text: mvention may be more ready understood I have nereunto appended sheets
drawings illustrative thereof to which by figures and letters reference is made in the
following description:-
Figs. 1, 2 and 3 are side, sectional end and top views respectively of mechanism
produced in accordance with my invention and for manual operation.
Fig. 4 is sectional end view showing a peculiar form of roller used in my said
niechanism.
Figs. 5 and 6 are drawings in detail (enlarged scale) showing the formation of
the material produced by the machine.
Figs. 7 and 8 are sectional side elevation and end view illustrative of an
arrangement followed in the production of mechanism to be operated by power, the
frame work being emitted in order that the operating parts may be more clearly
seen, and as the several parts are alike on both sides of the machine only one side
is shown by Fig. 8.
In carrying any invention into effect 1 make use of suitable framework a a which
is of any convenient length and width, and at one end of this framework a a
I mount a roller which revolves freely on its bearings.
C
Wound around the roller is a web of woven wire of the strength or thickness
required.
This web of wire e is carried from the roller b through a slot made longi-
tudinally in the roller d, across the machine to a roller (which is furnished with
pins that radiate from its periphery in such a manner as to lay hold of the woven
wire e passing over it) thence to the roller g on which it is coiled or wound.
The rollers and revolve freely on their axles, while the rollers d and are
held against revolving by the ratchets h and k and ratchet wheels k¹ respectively,
thus when the web c is held at one end by the pins on the roller and the
roller is rotated in the direction of the arrow m said web e will be stretched
between these rollers and d to enable the operation, hereinafter described to be
carried out.
When the web or woven wire e is distended as above described, pads n of silicate
cotton or slag-wool or asbestos fibre are placed thereon or secured thereto by means
of wires oo passing over same, these said wires oo being supplied from reels PP
through bent needles which pass through the web e to form a shed or opening
beneath, through which opening another wire supplied by the reels is drawn by a
booked rod or otherwise, the ends of the doubled wire thus drawn through
being bent over the edge of the web e as shown by Fig. 6, thus it is secured in
position. The wires o o as they are delivered from the reels pp pass over hanging
jullies having weights in order to allow the necessary movements of these
wires oo and yet keep them in a proper state of tension. Small weighted wires or
cords passing over or under the grooved flanges of the reels are employed
to prevent these latter from over-running, while a clamping device consisting of the
pieces lined with leather, indiarubber, or the like, and held together by bolts, is
employed for keeping the wires oo in their relative positions.
The needles are grooved at the back and have openings near their points (as shown
in detail drawings Figs. 9 and 10) so that the wires oo may lie therein and pass
therethrough, while they are further mounted upon a bar or frame in order that
they may be handled by the operater to pass them through the web e and on the
securing of the wires then to withdraw these needles to again move them over
the top of another of the pads as will be understood.
After one stretched portion of web c has been supplied with pads a then the
ratchet is thrown back and the roller g is rotated by its winch until all the
padded or prepared part has passed over or on to the roller on which the ratchet h
is again placed in position and the roller d by its winch d² is rotated as and for the
purposes above described.
In adapting my mechanism to be operated by power I mount the needle bar r
on lever arms to one of these being mounted on one side of the machine the other
on the other side thereof. These arms are caused to oscillate by the cams w

page_text: through the medium of the levers w³ and rods w³ as said cams rotate with the
shaft w upon which they are mounted, in order that the needles may be thereby
at one time caused to pass through the web of wire c and enter the openings
made in the stationary race z as shown by full lines in Fig. 7 at which time the
cam y strikes the lever arms y' thus moving the sliding piece y' and so throwing
the shuttle y across the racer, while at the other time said cams w¹ cause the
needles to rise out of this position into the one shown by broken lines of said
Fig. 7 on which a row of pads are supplied thereto (by any appropriately formed
mechanism, such as a travelling belt having provision for carrying properly
prepared pads, and operating mechanism for causing it to advance as hereinafter
described, together with appropriate mechanism for pushing said prepared pads in
regular order from said belt onto the said web of wire at this time) ready for the
operations to be repeated.
As the needles are rising out of contact with the web e the clamping device
which in this case slides on the bearings formed on the framework of the
machine, is caused to recede by the springs from its forward position shown by
full lines Fig. 7 into its rear position shown by broken lines of said Fig. 7 in which
position it is arrested by its levers coming into contact with the stop-piece *
although the rods (through which it is operated by same being coupled to the
lever arms w) may continue their motion; in this manner the wires fed to the
needles are kept at the desired tension and are further supplied to said needles without
any more strain being put upon these latter than is necessary to keep the wires
straight and in order. Also during the said rising motion of the needles and at the
time when they are just raised clear of the web c, the rollers and are caused
by any suitable ratchet lever and wheel mechanism to rotate and advance the said
web e through a space equal to the breadth or width of one pad n at which time
also other mechanism is, by any appropriate device as a lever arm operated by a
cam, causing a row of pads to be slided from the supply belt (which is coupled, as
by the beans upon which it is mounted being geared with those at and d², to
travel with and as said web e travels) on to said web as above described.
Although the backing and means for attaching the padding material thereto are
herein referred to as being of wire, it will readily be seen that the mechanism
made in accordance with my invention may be employed with equal advantages
for attaching similarly bulky materials or substances to other classes or kinds of
backing.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. The mechanism berein described for attaching pads of material to a woven or
otherwise prepared backing substantially as specified.
2. In mechanism for the purpose described, the combination of means for holding
a piece or pieces of woven wire, a series of needles carried by a bar for operating in
connection with said woven wire, and means for supplying a series of wires to said
series of needles, substantially as herein set forth and described.
3. In mechanism of the nature specified, the combination of a web or webs of
woven wire, rollers for supporting same constructed as described, a series of
needles, a series of wires arranged to be supplied to said needles, means for holding
said wires in position and tension regulating mechanism for same substantially as
set forth.
