WILLIAM FRASER Engineer 6 Livery Street Birmingham, do hereby declare the
nature of this invention to be as follows:-
The object of this invention is to obtain a perfect Tap or valve Union & hose pipe
connection.
In carrying out this invention it can be applied to Leather, Canvass, Rubber, or
any other kind of hose or pipeing or any kind of water or beer taps or valves or Gas
or any other kind of connections, and can be made in any kind of metal or suitable
material.
Figure I. is a full sized drawing of " Union & Coupling combined. A is a rubber
washer, with a hole right thro' same the size required to fit the tap or valve that is
to be operated upon, & fits into the interior of B, the external of same being screwed
to fit C. the internal of same being screwed & tapered to fit the former (i.e. a screwed
tapered nut).
D. is a collar the outside of which is milled, square, 6 or 8 sided or any other shape
suitable.
E&F. respectly. are screwed and tapered the very same as C. & B.
G. is a coupling tail suitable for inserting into the hose or pipe. The open space
marked H. receives the hose or pipe proper, i.e. the same is pushed over G, & is
encased between the inside of F. & outside of G. The former being split or cut into
six or eight claws or thereby of sufficient depth to ensure compression when Nut E.
is rotated or revolved, i.e. by revolving nut E. which is screwed & tapered, F. being
also screwed & divided into claws or sections, between each section or claw a slot or
open space interveanes, then by rotating E. F. is compressed, the open slots or space
between the claws provides the necessicary space for compression. The pipe or hose
is therefore held fast between F. & G.
The very same principal is applied at the other end.
The ends of the claws are turned inwards at both ends.
The top end to prevent the rubber washer A. from coming out. The bottom end to
ensure the claws holding the pipe or hose, same being held securely between F. & G.

page_text: By rotating . B. compresses the rubber washer A. to any degree of tightness
required, being then simply pushed on to the tap or valve the pressure from the
rubber washer is sufficient to hold it on.
Figures II. & III. shew the Union, & coupling disconnected or in two seperate
parts either of which can be used seperately or together.
Figure IV. shews a double coupling, suitable for connecting two pieces of hose or
pipe. The other figures shew the various ways, the same principal can be applied
without screwing & also that any of the Unions & connections can be fastened to the
Tap or valve by means of a strap or otherwise if required.

Improvements in Tap Unions, Valve or Hose Pipe Connections.
I, WILLIAM FRASER of 6 Livery Street Birmingham, in the County of Warwick,
Engineer, 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 said invention consists of the improvements hereinafter described, in couplings
or connections for flexible and other hose, pipes, speaking tubes, feeding bottles, soft
metal tubes and the like, and also in connections for taps, valves, unions and the like,
without making a permanent, soldered, or screwed joint.
Figure 1 represents in front elevation, a combined hose coupling, and union,
constructed and arranged according to one form of my invention. It will be seen
that the coupling tail upon one end, is shown naked, while the other end represents
a length of lose secured to the coupling, by means as hereinafter described.
Figure 2 represents partly in elevation, and partly in vertical section, the said
combined coupling and union-figure 1.
The same letters of reference, indicate corresponding parts in figures 1 and 2.
a² are separate coupling tails, connected together, at their inner ends, by an
internally flanged and screwed union ring b, with capstan arms 62, by means of which,
the said union ring, is conveniently rotated, for connecting, and dis-connecting, the
said coupling inner ends.
The coupling tail a, consists of a bulbous outer end, and with a broad collar a² near
the said end, a stop collar a³, midway between the inner and outer ends, a screwed
plain part a near the inner end, and a socketed flange as at the extreme inner end,
working within the recess and against the shoulder 63, of the union ring b.
The coupling tail a', has a bulbous outer end, with collar a², stop collar a³, plain
outside screwed part at, and a larger outside screwed collar part a, which screws
within an inside screwed part 6, of the union ring b.
The broad collars a², form stops, for the inward placing of two and three ply hose,
while for a one ply hose, it forms an annular extension, between itself and an outer
part, between which, the material of the end of a hose pipe is gripped, as represented
in the sectional end of the said figure 2.
c, care sliding coupling sleeves, bell-mouthed at their inside outer ends, and collared
or throttled at their inside inner ends; and which said coupling sleeves, slide upon
the parallel screwed part at, of the inner ends of the coupling a, a¹.
d, d, are inside screwed collars or nuts, working upon the parallel wormed parts a*
of the coupling tails; so that by rotating the said screwed collars or nuts outwardly,
the sleeves c, are forced over the ends of the hose piping e, which are gripped or.
pinched between the inside walls of the said sleeves, and the outsides of the bulbous
tail ends, or between the insides of the sleeves, and the outsides of the bulbous tail
ends, and broad collars a², best seen in the sectional view figure 2.
To release the hose pipes, it is only necessary, to turn the screwed collars or nuts d,'

page_text: in the reverse direction, when the sleeves can be moved inwardly, from off the
hose ends.
The collar a³ may be put on subsequent to the nut, and secured by soldering or
closing means, while the union may be connected to the inner end of the screwed
part a of the coupling end, by spreading or jumping the metal outwardly into a
collar a', or by soldering a ring on to the said end, after connection.
Figure 3 represents another form of my invention, of a hose coupling without a
union, and with the tail ends, and hose securing sleeves constructed the same as that
already represented, with respect to figures 1 and 2.
Figure 4 represents another form of my invention.
a, a¹, are separate coupling tails. is a union ring, constructed essentially as in
figures 1 and 2.
a is an inner end of the coupling tail a, and a is an inner outside
screwed end, of the coupling tail a¹. c, e are coned and fixed sleeves, carried upon
the middle of the plain part a, and upon the front of the screwed part a³, of the
parts a and a¹, respectively; so that the sleeves in this case, remain stationary, and
have their outer ends slit or subdivided inwardly, so as to form jaws or clamps
between the insides of them, and the outsides of the bulbous tail ends, the hose ends
are gripped, on the said outer and subdivided ends being contracted or gathered
inwards, by a slightly internally tapered or coned sliding ring d.
Thus when a hose is required to be connected, or the two ends of a hose coupled,
their inner ends are simply slipped over the bulbous tail ends, and the sliding rings d
moved outwardly in the direction of the arrow, when the hose is firmly coupled.
Figure 5 represents another form of my invention.
In this modification, the sleeve is externally screwed and coned outwardly, and with
the said screwed part slit or divided longitudinally.
The gathering in of the divided and screwed coned part, is effected by internally
screwed collars if, with capstan handles d², which on being rotated outwardly, draws
the split or divided parts upon the bulbous tail ends, with the hose or pipe ends
between them. The same results can be obtained, by leaving the screwed parts of
collars d tapered, then to fix the hose, the collars d would be placed at the extreme
ends of sleeves c respectively, and revolved or turned towards the centre, instead of
from the centre.
a, a are bulbous coupling ends, c are fixed sleeves, coned outwardly, screwed and
sub-divided, and e is the hose or flexible pipe.
Figure 6 represents a single coupling, applied to the bib or depending nose of a
tap; and in order to make a sound joint, the connection and coupling, is provided
with a rubber or other yielding ring.
Thus a is the bulbous tail end, c is a sliding sleeve, between the latter and the
former, the hose is gripped and held. d is an inside screwed ring or nut, rotating
upon the parallel screwed neck part a. a' is a shoulder, to the tap coupling part as
whose upper end is both coned inwardly, and slit inwardly, and within the interior of
which, is rubber or other yielding ring or short tube f, enclosed by turned in ends a³,
for keeping the inside rubber facing in position. is a plain slide or ring, working
upon the cone part a³, which on being forced outwardly draws in the sub-divided claw
like outer end, and forms a tight joint, between the tap nose, and coupling.
Thus, to connect the coupling to a tap, with the slide d² resting nominally against
the shoulder a, force the coupling end over the nose of the tap, then press upwards
the slide d², when a secure and sound connection can be made.
Figure 7 represents a modified form of my invention, in which the adjustable
coupling end is provided with an ordinary tail coupling. The drawing too, and
working of the adjustable part of the said coupling, is the same as that in figure 5.
The saine results can be obtained, by having the screwed part, in the nut or collar,
tapered, then to fix the union to the bib or tap, screw said nut or collar, from the tap,
instead of to it.
In figure 8, the adjustable coupling part is only screwed at its shank, and
marked a, and with the forward inside part d³ of the collar d. plain, and working upon

page_text: The rear inside part , of the collar d, is screwed, and takes upon the parallel
screwed part a', to which the ordinary coupling tail g is connected; so that by turning
coller d forwardly, the partially divided outer end a, is drawn together, thereby
drawing the inside rubber facing, up to the nose or spout of the tap.
Figure 9 represents another form of my invention, in which the same is represented
shown in connection with a tap. In this form, the coupling is internally chambered,
for preventing concussion or vibration on the hose pipe, when the tap on same, is
suddenly closed; this is accomplished, by providing the inside coupling, with an air
chamber, wherein the air enclosed, cushions the water, when the tap on the hose pipe
is suddenly closed.
a is a bulbous ended coupling tail, a² a broad collar near to it, a³ is a stop collar,
a is an outside screwed shank part, and as an annular shoulder, upon a screwed
fore part of which, the tap coupling a with a coned, and sub-divided front part, is
secured.
d² is a slide, which works upon the plain fore part of the said tap coupling a³; so
that by sliding upwards the slide d, the sub-divided fore part is contracted, which
compresses the rubber inside facing upon the outside of the tap. The same results
may be obtained, by having d² tapered internally, the opposite way, and having as also
tapered the opposite way.
a. is an inside casing, arranged concentric with the inside of the outside part a, a,
thus leaving an intervening space a', between the said parts, and access to which is
gained by a hole a; so that when the coupling is in use, air accumulates within the
annular space a', and cushions the water pressure, thereby preventing concussion or
vibration, when the tap, on the.hoso, is suddenly closed.
The coupling can be assisted or held in position, by a buckle strap h, which is
connected at its ends to the coupling, and with the loop part passing around the body
of the tap.
Figure 10 represents another form of my invention, in which the sleeve c, which is
tapered internally, and the inside screwed collar or nut d are made in one piece; so
that by rotating the said part d, (which is milled, or has facets made for a spanner
to work it.) the sleeve c is moved backwards or forwards upon the wormed neck part
of the coupling, by being rotated from the centre, towards the ends, holds or grips the
hose, on the same principle as described in figure 2.
Figure 11 represents my invention applied to the teat and tube of a child's feeding
bottle.
I wish it to be understood, that I am aware that the loose and sliding coupling
sleeve, and the bulbous coupling tails, are old.
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 :-
First. Operating or moving forward, and affixing in position, the securing sleeves
of hose unions, couplings or other connections, of the kind, as herein described, by an
internally wormed collar, nut, or its equivalent, screwing and travelling upon a
wormed outside part of the said hose union, coupling or connection, as set forth in
figures 1 and 2.
Secondly. Providing the coupling tails of hose unions, and other like connections,
as herein described, with a swell or enlargement a², for the purpose, substantially as
described and set forth in figures 1, 2 and 9.
Thirdly. The combination of a union, with a hose or other coupling, substantially
as described and set forth in figures 1, 2, 4 and 10 of the drawings.
Fourthly. A solid double tail coupling, with hose sleeve operating screw collars,
working upon the screwed shanks, substantially as set forth in figure 3.
Fifthly. Making the gripping sleeves c, of hose couplings or other like connections,
fixedly connected to, or made in one piece with, a bulbous tail end, and with the said
sleeve, partially slitted, or longitudinally divided from front to rear, and which slitted
or sub-divided part, is contracted or closed in, either by a plain slide, or ring d, as in

page_text: '
figure 4, or by an internally wormed ring or collar, screwing upon the wormed slitted
end of the sleeve, as in figure 5, already described.
Sixthly. In a combined tap and hose coupling, or other connection, constructed
and arranged, as herein described and set forth in figures 6, 7 and 8.
Seventhly Combining with a tap connection, of a yielding internal facing f;
enclosed within the inside of a slitted or sub-divided connection a', as, in figures 6,
and 8, and as in figure 9 as set forth.
Eighthly. Providing the inside of a hose, or other coupling, or connection, as
herein described, with an annular space, wherein air accumulates for cushioning the
water pressure, as set forth in figure 9, and already described.
Ninthly. Carrying or making in one piece, the coupling sleeve c, and an internally
wormed collar or nut d, or its equivalent, as set forth in figure 10.
Lastly. The various forms of hose, and other couplings, and connections, as already
described, illustrated, and set forth, in the several figures of the drawings.
