I HENRY HARRIS LAKE, of the firm of Haseltine, Lake, and Co Patent Agents,
Southampton Buildings in the County of Middlesex do hereby declare the nature
of my invention for "IMPROVEMENTS IN THE MANUFACTURE OF METALLIC TUBING
to be as follows :-
27
This invention has for its object to provide improved metallic tubing which is
formed by spirally winding a metal strip, having a doubled channelled or S shape,
in such a manner that the edge of one of the channels of the strip which is being
wound is laid in the other channel of the part already wound.
An india-rubber strip wound between the convolutions of the metal strip ensures
the tightness of the tube.
The improved metal tube presents a certain flexibility and may be advantageously
employed for any of the purposes for which india-rubber tubing is employed,
especially for watering, as tubes of pumps or the like. These metal tubes possess
greater strength than india-rubber tubes.
In carrying the said invention into practice I employ a strip or band of copper
iron or other metal the section of which is in the form of two channels facing in
opposite directions or in the form of the letter S one channel having its convex
side towards the exterior of the tube and the other having its concave side towards
the exterior.
This band or strip is wound spirally, the outer edge of one channel being laid in
the other channel.
At the same time as the metal band or strip is wound a small band of caoutchouc
or india rubber is also wound with it in such a manner that the latter is enclosed
between the two adjacent edges of the metal band and forms a tight joint whilst
at the same time giving a certain flexibility to the tube.
The tubing can also be formed of a band of metal having inwardly turning
edges, the caoutchouc or india rubber packing being located in a channel.
The caoutchouc or india-rubber can be replaced by any other suitable packing,
such as string.

page_text: I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co, Patent Agents,

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 :-
An
This invention has for its object to provide improved metallic tubing which is
formed by spirally winding a metal strip, having a double channelled or S shape,
in such a manner that the edge of one of the channels of the portion of the strip
which is being wound is laid in the other channel of the part already wound.
india-rubber strip is generally wound between the overlapping portions of the
metal strip and ensures the tightness of the tube; in-certain-enses, however, this
india-rubber-strip is not necessary.
The improved metal tubing possesses certain flexibility, and may be advan-
tageously employed as garden or fire hose, as flexible gas tubing, as the supply and
delivery pipes of pumps, as the flexible tubes of compressed air or vacuum brake
apparatus, and in general as a substitute for ordinary flexible india-rubber tubing.
The metal tubing moreover possesses greater strength than india-rubber tubes.
The said invention is illustrated in the accompanying drawing, the figures of
which are hereinafter described.
In carrying the said invention into practice I employ a strip or band, of copper,
iron or other metal having the section shown in Figure 1, (which is drawn to an
enlarged scale) that is to say having two channels turned in opposite directions;
one channel a having its convex side towards the exterior of the tube and the
other having its concave side towards the exterior.
This band or strip is wound spirally as shown in longitudinal section in Figure 2,
and in elevation in Figure 3, the outer edge of the channel a being laid in the
channel b.
At the same time that the metal band or strip is wound, a small band e of india-
rubber is also wound with it, as shown in Figure 3, the said band being enclosed
between the two adjacent or overlapping edges of the metal band, and forming a
tight joint, whilst at the same time giving certain flexibility to the tubing.
The tubing can also be formed of a band of metal haying inwardly turning edges
as shown in Figure 4; in this case the packing is located in the grooves formed by
the said edges.
The india-rubber can be replaced by any other suitable packing such as string or
the like. Or as in Figure 5, the packing can, in certain cases, be-dispensed with
the metal being alone capable of ensuring complete tightness.
I will now proceed to show by way of example, how the improved tubing can
be applied when connected to the branch of a gas pipe, a lamp, a gas-stove or the
like. I employ for this purpose a joint which enables the tube to be adapted to
existing cocks having nozzles as shown in Figure 9.
This joint is represented in section Figure 6 and in front view and side elevation
respectively in Figures 7 and 8; Figure 9 shows the joint fitted to an ordinary
nozzle.

page_text: At the extremity of the flexible tube is fixed, by solder or otherwise, a ring e,
which has external screw threads for the application thereto of a socket f, which is
screwed onto the said ring and is provided with a lateral opening :
In applying the tube with the joint thereon the joint is placed against the nozzle
in an inclined position so that the nozzle enters the lateral opening of the
socket f
When the nozzle is inserted, the joint is straightened so that the
projections at the top of the lateral opening engage above the enlargement of
the nozzle. The extremity of the nozzle is thus pressed against the end of the
pipe T. At this point a small washer of india-rubber, leather, lead or the like can
be placed to form a hermetically tight joint; or the solder which unites the ring e
and the tube T can be used for this purpose. To form a perfect joint between the
nozzle and the end of the tube it is sufficient to turn the socket in order that the
latter shall be screwed upon the threads of the ring e and shall press against
the enlargement of the nozzle.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed as communicated to
me by my foreign correspondent I declare that what I claim is,
The improved metallic tubing consisting of a continuous metal band or strip
having two channels turned in opposite directions, the said strip being wound
spirally so that the outer edge of one channel lies in the other channel, with er
without a hand of india rubber or other packing material interposed between the.
overlapping edges of the band or strip thus wound to form a hermetic joint.

DIVIFICATION,
Improvements in the Manufacture of Metallic Tubing.
I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake & Co, Patent Agents,
Southampton Buildings, in the County of Middlesex, 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:—
An
This invention has for its object to provide improved metallic tubing which is
formed by spirally winding a metal strip, having a double channelled or S shape,
in such a manner that the edge of one of the channels of the portion of the strip
which is being wound is laid in the other channel of the part already wound.
india-rubber strip is generally wound between the overlapping portions of the
metal strip and ensures the tightness of the tube; in certain cases, however, this
india-rubber strip is not necessary.
The improved metal tubing possesses certain flexibility, and may be advan-
tageously employed as garden or fire hose, as flexible gas tubing, as the supply and
delivery pipes of pumps, as the flexible tubes of compressed air or vacuum brake
apparatus, and in general as a substitute for ordinary flexible india-rubber tubing.
The metal tubing moreover possesses greater strength than india-rubber tubes.
The said invention is illustrated in the accompanying drawing, the figures of
which are hereinafter described.
In carrying the said invention into practice I employ a strip or band, of copper,
iron or other metal having the section shown in Figure 1, (which is drawn to an
enlarged scale) that is to say having two channels turned in opposite directions;
one channel a having its convex side towards the exterior of the tube and the
other b having its concave side towards the exterior.
This band or strip is wound spirally as shown in longitudinal section in Figure 2,
and in elevation in Figure 3, the outer edge of the channel a being laid in the
channel b.
At the same time that the metal band or strip is wound, a small band c of india-
rubber is also wound with it, as shown in Figure 3, the said band being enclosed
between the two adjacent or overlapping edges of the metal band, and forming a
tight joint, whilst at the same time giving certain flexibility to the tubing.
The tubing can also be formed of a band of metal having inwardly turning edges
as shown in Figure 4; in this case the packing is located in the grooves formed by
the said edges.
'
The india-rubber can be replaced by any other suitable packing such as string or
the like. Or, as in Figure 5, the packing can, in certain cases, be dispensed with
the metal being alone capable of ensuring complete tightness.
I will now proceed to show by way of example, how the improved tubing can
be applied when connected to the branch of. a gas pipe, a lamp, a gas-stove or the
like. I employ for this purpose a joint which enables the tube to be adapted to
existing cocks having nozzles as shown in Figure 9.
This joint is represented in section Figure 6 and in front view and side elevation
respectively in Figures 7 and 8; Figure 9 shows the joint fitted to an ordinary
nozzle,

page_text: At the extremity of the flexible tube is fixed, by solder or otherwise, a ring e,
which has external screw threads for the application thereto of a socket f, which is
screwed onto the said ring and is provided with a lateral opening g.
In applying the tube with the joint thereon the joint is placed against the nozzle
in an inclined position so that the nozzle enters the lateral opening g of the
socket f. When the nozzle is inserted, the joint is straightened so that the
projections at the top of the lateral opening g engage above the enlargement of
the nozzle. The extremity of the nozzle is thus pressed against the end of the
pipe T. At this point a small washer of india-rubber, leather, lead or the like can
be placed to form a hermetically tight joint; or the solder which unites the ring e
and the tube T can be used for this purpose. To form a perfect joint between the
nozzle and the end of the tube it is sufficient to turn the socket fin order that the
latter shall be screwed upon the threads of the ring e and shall press against
the enlargement of the nozzle.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed as communicated to
me by my foreign correspondent I declare that what I claim is,
The improved metallic tubing consisting of a continuous metal band or strip
baving two channels turned in opposite directions, the said strip being wound
spirally so that the outer edge of one channel lies in the other channel, with or
without a band of india rubber or other packing material interposed between the
overlapping edges of the band or strip thus wound to form a hermetic joint.
