similar Purposes.
We, JOHN HUNTER of Sterling Valley, Cayuga County, Manufacturer, FREDERICK
WILLIAM TUERK Jnr. Machinist and JAMES CONRAD HUNTER Manufacturer both of
the City of Syracuse, in the County of Onondaga, State of New York, one of the
United States of America, 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 :-
Our invention relates to improvements in bands for hose couplings which are
clamped over the hose to secure the coupling therein, and the object is to provide an
efficient and simple device which will evenly clamp the hose onto the coupling, and
securely retain the same in position.
And to this end our invention consists in a band of metal either cast or struck up,
formed with its central portion straight and its ends curved, so that it may be readily
bent into form without weakening the ends, and in strengthening the same by
providing ribs on the edges of the band, and extensions oppositely located on the
respective ends, and in providing the ends with recessed and counter-sunk apertures
for the passage of the clamping bolt.
It consists also in the datail construction and arrangement of the parts,
all as hereinafter more fully described and pointed out in the claims.
In the accompanying drawing
Figure 1, is a top plan of the blank from which our improved band for hose-
couplings is formed.
Figure 2 is an isometric view showing the underside of the blank and the curved
ends provided with the oppositely arranged extensions.
Figure 3 is an isometric view of the blank bent up in shape and provided with the
clamping-screw, illustrating particularly the shape of the recess which holds the nut
of the clamping bolt or screw.
Figure 4 shows the device applied to the hose, clamping the coupling in
position.
Figure 5 is a transverse section taken on line x, x, Figure 3; and

page_text: Figure 6 is a side view of a hose and coupling with the band in place
thereon.
A represents the blank from which our improved band for hose couplings is formed,
and the same may be struck up or cast of suitable metal which will permit the same
to be bent into form as presently explained.
The blank A has a straight central portion B Figure 2 and curved ends C, C, and
is provided with the ribbed edges a, a Figure 1, b, b, Figure 2, and with the
oppositely arranged extensions, E, E, Figure 2 and the ends D. D Figures 1 and 2.
The ribs a, a, b, b, are provided to strengthen the blanks when bent into form, and
the curved ends C, C, are provided in order that when the blank is bent in shape, the
bend comes on the straight portion B, thereby permitting the blank to be shaped
without weakening the ribbed ends C. C.
The ribs a, a, on the curved ends C. C, of the band are made flaring at a' from the
central straight portion B, of the band A, the flaring ribs terminating at the top or upper
extremity of the lugs D, when the band is formed into shape; the object of thus flaring
the ribs is to impart great strength and stiffness to the lugs D with the minimum
quantity of metal at this point, and the desired result is thereby secured as the curved
ends are unaffected by bending the band into shape, while the flaring ribs serves as a
brace or tie against the draw of the clamping bolt in clamping the band on the hose L
to secure the coupling therein.
The ribbed ends C, C, D, D, form lugs when the blank is bent in shape as best
shown in Figures 3 and 4, and one of said lugs D has a recess g¹ between the
flaring ribbed edges a, a, into which the nut of the clamping bolt G, is inserted and
held by the flaring ribbed edges a¹ a¹ to hold the nut when the bolt is turned to clamp
the band onto a hose and coupling.
The opposite lug D, is provided with the counter sunk hole f¹, for the head I
Figure 4, of the clamping bolt G.
The extensions E, E, as will be observed are located on opposite edges of the ends DD
of the blank, and when the blank is shaped the said extensions E E form tongues
which lap into the opposite bend of the band and form a continuous circular clamp
which is rendered adjustable or compressible by tightening up or unscrewing the
clamping bolt G.
The object of providing the projecting tongues E is to provide means for compressing
the material of the hose uniformly, and thus evenly clamping the hose to the
coupling.
In all of the bands for hose-couplings now used, no provision is made for this purpose,
and the band clamps the hose to the coupling and squeezes the material of which the
hose is composed into a fold between the two jaws or lugs of the clamp, thereby
straining the hose out of shape and weakening the same without securely holding
the coupling in place, and by frequently tightening and loosening the band,
the end of the hose becomes frayed out and destroyed, rendering it necessary to cut
off the end.
The main difficulty in the use of the old band results from the insecure and uneven
clamping of the hose to the coupling.
Our invention remidies this defect for the reason that the extensions E, E, bear
against the hose from opposite sides and exert the pressure equally thereon so as to
tighten or compress the material circumferentially, and evenly clamp the hose to the
coupling.
Furthermore, the old band for hose-coupling is necessarily weak at the clamp for
the reason that the clamp screw compresses the lugs at the point furthest from the
circumference of the coupling, and the tendency is to break the lugs off, while in our
improved band the extensions E. E pass under the opposite bends of the band A and
underneath the lugs D, D, thus affording a circumferential hold entirely around the
hose, strengthening and stiffening the lugs so that the clamp screw compresses the
band evenly without twisting, and thereby weakening the lugs in the operation.
It will be observed that the projecting ribs bb leave a channel or recess in the under
side of the band, and the extensions E. E. slide in the said recess and are prevented

page_text: from squeezing out laterally as the band is compressed, the opposite edges serving to
guide the extensions within the recess and forming a wall or flange to prevent the
extensions from squeezing out.
The operation of our invention will be readily understood from the foregoing and
from a consideration of the drawings.
The blank A is bent in shape on the straight portion B, and the bolt G is provided,
and the device is applied to the hose L over the coupling N which is provided with
the union M as shown in Figures 4 and 6, and the band is clamped securely on to the
hose with a screw-driver, the nut H being securely held in the recess g₁ against the
flaring ribbed edges a¹ a¹ and the band A may be readily removed by loosening
the screw bolt G.
The ribbed edges b b serve also to compress the material of the hose against the
thread of the coupling N, thus serving to provide a very secure connection of the
coupling to the hose.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is;
First. The herein described blank for hose-coupling bands consisting of a metal
band having
a straight central portion and curved ends provided with oppositely
arranged projecting extensions formed integral therewith, the longitudinal edges of
the blank adjacent to the extensions being provided with ribs which form guides for
the extensions when the blank is bent into shape for use, and the ends of the blank
provided with holes for the clamp bolt substantially as and for the purpose set
forth.
Second. As a new article of manufacture, a hose coupling band formed of metal
having oppositely arranged extensions on its ends interlocking with ribs formed on
the inner edges thereof, and a clamp bolt passing through lugs on the ends of the
band to secure the band on the hose coupling, substantially as and for the purpose set
forth.
Third. The combination of the band A having oppositely arranged projecting
extensions E E, ribs bb on inner side adjacent to the extension E, ribs a on outer side
of the band, lugs D D, recess g' for the nut H, and the bolt G, all substantially as and
for the purpose set forth.
Fourth. The cast metal hose coupling band A, having extensions E E oppositely
arranged on the ends thereof, ribs b on the inner side of the band, lugs D D on the ends,
and strengthening ribs a a¹ flaring to the top of the lugs, substantially as and for the
purpose set forth.
