WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent
Agents, Southampton Buildings, London. "IMPROVEMENTS IN AND RELATING TO
DEVICES FOR SECURING HOSE OR FLEXIBLE PIPES UPON THEIR COUPLINGS, AND
FOR SIMILAR PURPOSES." [A communication from abroad by John H. Hubbell,
of Boston, and Freeborn Fairfield Raymond, of Newton, Gentleman, both. in
Massachusetts, United States of America.]
This Invention relates to devices whereby hose for conveying water or the like
and any similar articles may be secured or attached to couplings or other objects,
and whereby breakages may be repaired and extensions made in an easy, simple,
and durable manner with ordinary blacksmiths' pinchers or pipe tongs, or pliers
commonly used by gas fitters.
The said Invention also relates to apparatus for applying such devices in the
position they are to occupy.
One of the devices made according to this Invention consists of a strap or band
punched from a strip of sheet metal of sufficient length, having a tongue or
projection at one end and an aperture or slot at the other end, into which in
locking the strap on the band the end of the tongue is inserted, and through which
it is drawn by the implements above named, or any other suitable device, and

page_text: turned over upon the band. It is not essential however that the tongue be in one
piece with the band, as in lieu thereof I may cut the separate tongue from the
centre of the strap, provide an additional slot in the other end of the band, and use
the tongue thus cut as a loop in fastening the two ends of the main portion of the
band together. The band may also be provided with projections or starts which
are used as abutments against which the jaws of a vice, tongs, or pinchers may
rest, while bringing the two ends of the band together.
Another device which is adapted to the larger kind of hose, such as fire hose, is
constructed as follows, that is to say:-A strap of sheet metal is provided with a
burr, and a hook is formed on one end of the strap and is hooked into one side of
the burr, its free end being so adjusted as to lie next the hose at a point about the
middle of the neck of the coupling, which should be made in the usual manner,
either corrugated along the whole length as is usual in small couplings, or beaded
at its inner end. The strap is then passed through the other side of the burr and
tightly drawn up, so as to embed itself in the hose and compress the hose firmly
upon the neck of the coupling. It is best to make the burr of thicker metal than
the strap. It is obvious that round wires may be used in lieu of flat metal, either
singly or in gangs, in connection with this burr. The burr is a piece of metal with
a suitably shaped hole pierced in it to receive the band. If the band is of round
wires, this hole may be formed either round or oval, so as to give a considerably
transverse bearing to the wires, or it may be formed oblong and a gang of wires be
used.
In order to fasten or secure the device it is desirable to have a tool composed of
a flexible strap or chain adapted to surround the coupling over the place of the
band, and to be drawn together by a screw or other power, so as to shorten the
band by actual pressure upon its exterior surface, and embed it in the compressible
material of the hose itself, thereby bringing it into close contact with the neck of
the coupling, and thus allowing the band to be drawn through and turned back
over the burr. I therefore provide a tool for this purpose which is made as
follows, that is to say:-I employ a yoke having attached to it at one end a
flexible chain or strap, which chain is provided with abutments which may consist
of flexible rolls of an ordinary lathe-chain. At the other end of this yoke is
pivoted a nut through which works a hand serew carrying on its end a swivelled
jaw to take hold of the abutments referred to in the flexible strap. The hose
being slipped upon the coupling, a burr having a strap attached to it is put round
in its proper place, and the free end of the strap passed through the burr upward.
This apparatus is taken and the flexible band put round the hose, and the
abutment is engaged with the jaw. The burr should be adjusted so as to come at
the place of the yoke, the end of the yoke to which the chain is fastened being
placed over the edges of the burr. Upon tightening the screw it will be seen that
the burr is itself drawn down upon the hose. The band is then compressed by the
chain or its equivalent into and upon the hose throughout the entire circum-
ference of the hose, and will thus be shortened by the traverse of the chain over
it, and will be forced up at its free end through the burr. When a sufficient
amount has been protruded through the burr, the free end is turned down
and clinched by hammer or otherwise, and the screw being loosened it will be
found that the hose is tightly banded to the coupling. By this apparatus a
sufficient strain can be brought to bear upon the exterior of the hose in the place
of the band to crush the neck of the coupling itself, and consequently it is very
evident that it is easy with this simple tool to repair with these bands a large
piece of hose which may happen to burst on occasion of a fire in a street, simply by
cutting off the broken part of the hose and re-inserting the coupling or a short
piece of tube.
This method too offers great advantages for the coupling together of inflexible
pipes by means of flexible wrappings or tubes connecting their ends, which is a
desirable thing in hydraulic mining. So also these bands may be readily applied
by described apparatus to any compressible covering for a non-compressible core.

page_text: Various modifications of the style of hose bands herein described may be
employed without departing from the same principle, namely, a loop, hole,
aperture, or projection at one end of the band, which furnishes an abutment or
rest for the other end of the band, which is drawn over it tightly and then
bent down and clinched.
The bands may be used for compressing any flexible or elastic material upon
a metallic core of any other construction than that of a coupling.

This Invention relates to hose couplings, clamps, or fastenings which are not of
the common kind known as hose couplings, but are new and useful devices whereby
hose for conveying water, or the like, and similar articles may be attached to
couplings or other objects, and whereby breakages may be repaired and extensions
made in an easy, simple, and durable manner with an ordinary blacksmiths' pincers
or pipe-tongs, or pliers commonly used by gas fitters. The said Invention also
relates to apparatus for applying such devices in the position they are to occupy.
One form of the clamping device made according to this Invention is shewn in

page_text: .
Figures 7, 8, and 9, and consists of a strap or band punched from a strip of sheet
metal of sufficient length, and having a tongue or projection at one end, and an
aperture or slot at the other end into which in locking the strap on the band the
end of the tongue is inserted, and through which it is drawn by the implements.
above named or any other suitable device, and turned over upon the band,
substantially as shewn in Figure 7. It is not essential however that the tongue
be in one piece with the band, as in lieu thereof I may cut a separate tongue
from the centre of the looped strap, provide an additional slot in the other end of
the band, and use the tongue or crossbar thus cut as a loop in fastening the two
ends of the main portion of the band together, as shewn in Figures 10, 11, and 12.
The band may also be provided with projections which are used as abutments,
against which the jaws of a vice, tongs, or pincers may rest while bringing the two
ends of the band together, substantially as shewn in Figure 8.
Another form of the clamping device which is adapted to the larger kinds of
hose, such as fire hose is shewn in Figures 1, 2, 3, 4, 5, and 6.
A is the coupling, formed in the usual manner of metal, and properly prepared
on its exterior to receive the flexible hose; B is the flexible hose, which is adapted
to be slipped over the coupling in the usual manner; C is the burr; and D is the
strap. A hook is formed on one end of the said strap D, and is hooked into one side
of the burr C, its free end being so adjusted as to lie next the hose B at a point
about the middle of the neck of the coupling, which should be made in the usual
manner, either corrugated along the whole length, as is usual in small couplings, or
beaded at its inner end. The strap D is then passed through the other side of the
burr C, and tightly drawn up so as to embed itself in the hose and compress the
hose firmly upon the neck of the coupling. It is best to make the burr of thicker
metal than the strap.
I have described this contrivance as employing a burr and a strap of sheet
metal, but it is obvious that round wires may be used in lieu of flat metal, either
singly or in bundles, in connection with the burr above mentioned. The said burr
is a piece of metal with a suitably shaped hole pierced in it to receive the band.
If the band is of round wires, this hole may be formed either round or oval so as
to give a large transverse bearing to the wires, or it may be formed oblong and a
bundle of wires be used.
Although the burr and band of this apparatus bear a certain resemblance to a
cotton-bale-tie, yet when the nature of the operation of this apparatus is compared
with the nature of the operation of the cotton-bale-tie, it will be seen that there is
a fundamental difference between them.
A cotton-bale or any other bale of goods is compressible throughout its bulk,
and in the application of the ties they are put onto the bale somewhat slack, and
when the latter is compressed by machinery to a smaller bulk than it assumes
when banded and released from the press, so that the tightening of the bands is
due to the elasticity of the compressed material.
In the case of a hose, I employ a non-compressible core with a compressible
exterior which is to be bound to the non-compressible core, in order that it may be
so closely secured to the core as not to slide upon it longitudinally. In order to
do this it is necessary that the strain should be applied to the band, and that the
band itself should be positively forced into its compressing position.
In order to do this it is desirable to have a tool composed of a flexible strap or
chain adapted to surround the coupling over the band, and whose ends can be
drawn together by a screw or other power, so as to shorten the band by actual
pressure upon its exterior surface and embed it in the compressible material of the
hose itself, thereby bringing it into close contact with the neck of the coupling, and
thus allowing the band to be drawn through and turned back over the burr.
It will be seen therefore that while in a bale-tie both ends of the strap are
turned under and moused by the expansion of the compressed material, in this
band there is no opportunity to turn in the free end for the purpose of mousing it,
and reliance must be had upon the tensile strength of the metal and its stiffness at

page_text: the point where it turns over the burr. An apparatus. for this purpose is illustrated
in Figure 6, which shews the manner in which a chain compressor operates to fit
the band to its place.
F is a yoke having attached to it at one end a flexible chain, band, or strap G,
which is provided with abutments, which in this case consist of flexible rolls h of
an ordinary lathe-chain. At the other end of this yoke F is pivoted a nut I,
through which works the hand-screw K carrying on its end a swivelled jaw L to
take hold of the abutments referred to in the flexible strap.
The operation of this apparatus to apply one of the bands to its coupling is as
follows, that is to say:-The hose being slipped upon the coupling, a strap having a
burr attached to it is put round in its proper place and the free end of the strap
passed upward through the burr. The said apparatus is then taken and the
flexible band G put round the hose, and one of the abutments h is engaged with
the jaw L. The burr should be adjusted to a position beneath the yoke, the end
of the yoke to which the chain is fastened being placed over the edges of the burr.
Upon tightening the screw it will be seen that the burr is itself drawn down upon
the hose. The band D is then compressed by the chain or its equivalent into and'
upon the hose throughout the entire circumference of the latter, and will thus be
shortened by the traverse of the chain over it, and will be forced up at its free
end through the burr. When a sufficient amount has been protruded through the
burr the free end is turned down and clinched by a hammer or otherwise, and
after loosening the screw it will be found that the hose is tightly banded to the
coupling.
i
By this apparatus a sufficient strain can be brought to bear upon the exterior of
the hose at the place of the band to crush the neck of the coupling itself, and
consequently it is evident that it is easy with this simple tool or apparatus to
repair with the bands a large piece of hose which may burst on the occasion of a
fire in the street simply by cutting off the broken part of the hose and re-inserting
the coupling or a short piece of tube.
This method also offers great advantages for the coupling of inflexible pipes by
means of flexible wrappings or tubes connecting their ends, which is a desirable
object in hydraulic mining. These bands may also be readily applied by the
above described apparatus to any compressible covering for a non-compressible
core.
Various modifications of the forms of hose-bands herein described are shewn in
Figures 13, 14, and 15, and are applied in substantially the same manner and
involve substantially the same principles, namely, a loop hole, aperture, or
projection at one end of the band, which furnishes an abutment or rest for the
other end of the band, which is drawn over it tightly and then bent down and
clinched.
The bands may be used for compressing any flexible or elastic material upon a
metallic core of any other construction than that of a coupling.
Having thus fully described the nature of the said Invention, as communicated to
me by my foreign correspondents, and the manner of performing the same, I wish it
understood that I claim,-
First. A strap or band forming a clamp or fastening for hose stamped or punched
out of sheet metal in one piece and having perforations and corresponding tongues
or projections, substantially as above set forth.
Second. A strap or band forming a clamp or fastening to unite a flexible hose to

the said band at any degree of tension desired at the time, substantially as and for
the purposes described.
Third. The combination for hose coupling of hollow metallic core adapted to be
united in the usual manner to its counterpart upon the adjacent piece of hose, the
flexible hose enveloping and being slipped over the said hollow metallic core and the

end at any desired degree of tension, substantially as above set forth.
Fourth. As, a means of compressing the flexible pipe for a hose upon its end
