Improvements in Hose Couplings and Adjustable Clamps therefor.
I, WILLIAM YERDON, Manufacturer, of Fort Plain, in the County of Mont-
gomery, and the State of New York, do hereby declare the nature of my invention
and in what manner the same is to be performed to be particularly described
and ascertained in and by the following statement :—
In the accompanying drawings-
Fig. 1 represents a side elevation of the coupling band, constructed according to
my invention, with the adjusting clamp applied;
Fig. 2 represents a perspective view of the band:
Fig. 3 represents a detail perspective view of the upper part of the band, taken
from below, to show the tongue and groove.
A designates the hose coupling band, which is provided, as usual with two
corresponding lugs, a, arranged one on each side of the top opening, these lugs
being perforated to allow the passage through them of a clamping bolt B having a
nut & for drawing the coupling together on the hose. A broad, slightly curved
tongue, al attached to the said band on one side of the said opening extends
across the same below the said lugs, and enters a recess a² in the opposite side.
Its function is to cover this opening and prevent the material of the hose from
being pinched between the lugs. It also, by engaging the side walls a³ of the said
recess braces the upper part of the band against sidewise strain.
The body of the band consists of two parallel bars CC, which are united near
the said lugs, leaving a slot D between them. When the coupling band is
clamped on the hose the material of the latter rises into the slot, so that the
said band will have a much more secure hold on the said hose than would be
possible to a single solid band. It is indeed, a double band, united at the ends near
the lugs where the clamping takes place. This band may be made of any material
strong enough to resist the strain of the hose while allowing such an amount of
bending as is necessary to tighten it on the latter. Wrought iron or strong brass
is preferred.
2
On each side of the band near the end of the slot D a broad exterior
shoulder E is formed. These shoulders are designed to receive the pressure of
inwardly facing jaws f, which are formed on the upper ends of two curved bars F,
the latter being hinged together at the bottom by lugs f¹ƒƒ³ and pintley passing
transversely through them. These hinged bars with their jaws constitute an
adjusting clamp for tightening the band on the hose more effectually than the bolts
and lugs before mentioned above could do it. This is effected by putting the said
adjusting clamp and band fitted together, into any ordinary vice and operating, the
latter to close on the said arms. Then with very little exertion the coupling band
may be drawn upon the hose as tightly as desired and the bolt B and nut b will
hold it so.
Of course the said nut and bolt may be used also for tightening the
band, but with less effect. The shoulders and clamping arms may be used with a
band, which has no slot, as may also the tongue and grooves. The perforated lugs
and bolt are not new.
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. A hose coupling band having a groove or recess in its inner face on one side
of the opening and a single broad tongue extending across from the other side into
said groove so as to cover the said opening substantially as set forth.

page_text: 2. A double hose coupling band consisting of two bands or bars having a slab
between them but united near their ends substantially as set forth.
3. A hose clamping band provided with external shoulders, in combination
with an adjusting clamp bearing against the said shoulders to tighten the said
clamp on the hose for the purpose set forth.
4. A hose coupling band provided with external shoulders in combination with
an adjusting clamp bearing against the said shoulders and devices for holding the
band in position after being tightened on the hose by the action of a vice on said
adjusting clamp substantially as set forth.
5. An adjusting clamp for a hose coupling band consisting of two arms hinged
together and provided with jaws, and adapted to be held in a vice substantially as
and for the purpose set forth.
6. A hose coupling band provided with perforated lugs and external shoulders
in combination with a pair of hinged clamping bars having jaws adapted to be
forced by a vice against the said shoulders and a bolt passing through said lugs
to hold the said band as thus adjusted.
