Improvements in and relating to Hose-pipes.
I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent Agents,
45 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:-
The object of my improvement is to lessen the injury occasioned to hose of various
binds by bending or abrasion incident to its contact with the end of a nipple or
analogous part. Perhaps its most important application is to the hose used in.
connection with air brakes, where such hose is united to the nipples of metal
comprised in the connections.
My improvement consists in arranging intermediate the hose and nipple, a
yielding substance which will prevent any injurious action of the nipple upon
the hose. This intermediate substance may be made in the form of a cap or
facing piece applied to the nipple.
In the accompanying drawing I have illustrated my invention in connection
with brake hose and nipple. Figure 1 is a central longitudinal section of a
nipple and a cap or facing piece of yielding substance applied thereto. It also
shows a piece of hose and a clamp for fastening it. Figure 2 is an end view.
Figures 3, 4, 5 and 6 are views like Figure 1, except that the hose and its clamp
are omitted. Similar letters of reference designate corresponding parts in all
figures.
A designates a nipple which is represented as being of the ordinary kind used
for hose connections in railway brakes. It has an externally screw threaded
portion a, an angular portion a suitable for engagement by a wrench and a
portion a² on whose exterior the hose is to be secured.
B designates hose, which may be of ordinary construction, made up of an inner
tube or lining of soft rubber, external layers of cloth cemented together by soft
rubber and an exterior of soft rubber. A. clamp D is shown for securing the end
of the hose upon the nipple. This clamp may be of any suitable construction.
E designates a cap or facing piece of yielding substance, as for instance, soft
rubber. In Figures 1 and 2 this cap or facing piece is made in the form of a
cylinder adapted to be fitted upon that portion a³ of the nipple upon which the
hose B is fitted, and an inwardly extending flange e capable of lapping over the
extremity of the said portion a2 of the nipple
As here shown, the portion a² of the nipple has a circumferential rib a³ which
will conduce to retain the cap or facing piece in place. I have. here shown the
outer extremity of the cap or facing piece as provided with a circumferential
rib or enlargement e¹.
In Figure 3, I have shown substantially the same construction as in Figures 1
and 2, but here the outer portion of the part 3 of the nipple is provided with

page_text: an external screw thread a³, and the cap or facing piece is internally provided
with a screw thread e2 for engaging therewith.
In Figure 4, I have shown the same construction as in Figure 1, except that
I have here omitted the circumferential rib or enlargement e¹ which is illustrated
in Figure 1.
In Figure 5, I have shown that the outer portion of the part a² of the nipple
may be provided with an internal screw thread a6, and that the cap or facing
piece may be extended around the end of this part of the nipple, and into the
interior of this part of the nipple and provided with a screw thread e³ for engaging
with said screw thread a6.
"I'
In Figure 6, I have shown a cap or facing piece which is U-shaped in cross
section and adapted to embrace both the outside and the inside as well as to
protect the end of the part a² of the nipple.
I wish to cover broadly, as of the essence of my invention, a yielding substance
applied in the form of a cap or facing piece of any suitable construction so
that it, or some portion of it will occupy a position intermediate the end of the
nipple and the hose which is to be secured to the nipple, my object being to
present a yielding surface to the hose instead of subjecting it to the rigid and
necessarily somewhat rough extremity of the nipple. Thus I reduce the liability
of injury to the hose, at or near its point of contact with the extremity of the
nipple.
By the term nipple, herein, I wish not only to include what is strictly known
as a nipple, but all analogous parts, as for example, the end of any pipe, and
by the term hose, I wish to include everything in the nature of flexible tubing,
especially that comprising soft rubber.
It would be within the spirit of my invention to employ at the end of the
nipple only, a facing piece fastened appropriately to the nipple, as, for example,
a protuberant facing piece such as is shown in some of the other figures, pro-
jecting circumferentially further than the exterior of the nipple; it would be
within the spirit of my invention to employ such an end facing piece with an
inner piece fitting or engaging the inner surface of the nipple.
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:-
1. A hose nipple, the end to which the hose is to be attached being provided
with a yielding facing or cap, piece of soft, yielding material interposed between
the nozzle and hose to prevent injury by bending or abrasion, substantially as
described.
2. A hose nipple, the end to which the hose is to be attached being provided
with a yielding facing or cap piece having a flange or transverse portion over-
lapping the end of the nipple, substantially as described.
A hose nipple, the end to which the hose is to be attached being provided
with a yielding facing or cap piece having an exterior circumferential rim, sub-
stantially as described.
4. A. hose nipple, the end to which the hose is to be attached being provided
with a yielding facing or cap piece having a flange or transverse portion over-
lapping the end of the nipple and having an exterior circumferential rim, sub-
stantially as described.
