Year: 1884

page_text: PROVISIONAL SPECIFICATION.
I, ALEXANDER MELVILLE CLARK, of the firm of A. M. and Wm. Clark, of
53, Chancery Lane, in the County of Middlesex, Fellow of the Institute of Patent
Agents, do hereby declare the nature of the said Invention for "IMPROVEMENTS IN
HOSE COUPLINGS a communication to me from abroad by Garritt M Van Riper
and James O. St Clair, both of Republic in the County of Marquette, and State of
Michigan, United States of America to be as follows:-
"
This invention relates to that description of hose couplings in which, working on
a pivot upon opposite sides of one section of the coupling, is a lever handle piece
having hooks at its one end arranged to engage with pins on opposite sides of the
other section of the coupling, and it consists in a combination, with said handle-
piece, of links connecting it with the side pivots, and a rubber or elastic packing
interposed between the meeting end portions of the coupling sections, whereby
when the handle piece is closed to lock the coupling, its link connection serves, first,
to compress said packing, and afterwards, to admit of said packing yielding and
holding the handle piece in its locked position and the coupling closed.
The male sections of the coupling are arranged to enter one within the other at
their meeting end portions as usual and provided, the one section with one or more
lugs or guides, and the other with one or more corresponding recesses for said lugs
or guides to enter when putting the coupling together, for the purpose of adjusting
the coupling sections into proper relation with each other and holding the coupling
in place while coupling. The rubber or other elastic packing ring is inserted within
the enlarged head of the female section, for the entering end of the male section of
the coupling to bear against when closing the coupling.
The lever handle piece is arranged so as when closed to occupy a portion
lengthwise of the coupling upon the one side of it and to partly encircle the same.
It is made with two opposite side ears intermediately of its length in extended
partial encircling relation with the coupling, and to the extremities of which are
pivoted links that are connected at their opposite ends to central pivots on opposite
sides of the head or meeting end portion of the male coupling section; said handle

shaped extensions which engage with opposite central side studs or pins on the
female coupling section.
To close the coupling, after its two sections have been brought together, the
hooks of the handle piece are engaged with the pins and said handle piece shut
down or inward till the pivoted connection, of the links pass beyond the culminating
point of the links relatively to their pivots and the locking pins, or in other words,
beyond a straight line drawn to centrally intersect said pivots and pins. In this
action, the elastic packing ring will first be compressed, by the entered portion of
the male section, but afterward and as the pivoted connections of the links pass
their culminating point as described, will slightly yield and serve to hold the
handle piece in its locked position and the coupling sections securely closed.
To unlock the coupling, it is only necessary to move outward the handle piece
and to move it so that the hooks will pass out of the way of the locking pins when
or after which the coupling sections may be drawn apart.

53, Chancery Lane, in the County of Middlesex, Fellow of the Institute of Patent
Agents, do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN HOSE COUPLINGS" (a communication to me from abroad by Garritt M. Van
Riper and. James O St Clair both of Republic in the County of Marquette and
State of Michigan United States of America) and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement:
This invention relates to that description of hose couplings in which, working on
a pivot upon opposite sides of one section of the coupling, is a lever handle. piece
having hooks at its one end arranged to engage with pins on opposite sides of the
other section of the coupling, and it consists in a combination, with said handle-
piece, of links connecting it with the side pivots, and a rubber or elastic packing
interposed between the meeting end portions of the coupling sections, whereby
when the handle-piece is closed to lock the coupling, its link connection serves,
first, to compress said packing and afterwards, as said connection passes the
culminating point, to admit of said packing yielding and holding the handle-piece
in its locked position and the coupling secured closed, substantially as hereinafter
described.
Reference is to be [had to the accompanying drawings forming part of this
specification, in which similar letters of reference indicate corresponding parts in
all the figures.
Figure 1 represents a side view of the improved hose coupling enclosed, showing
also by dotted lines, the handle-piece in position for opening the coupling.
Figure 2 is a longitudinal view, looking in a direction at right angles to Figure 1
of one of the coupling sections, with its attached locking handle piece and
Figure 3, a view in perspective of the other coupling section.
A indicates the male section of the coupling and B the female section thereof,
arranged to enter one within the other at their meeting end portions as usual and
provided, that is the one section. A, with one or more lugs or guides b, and the
other section B, with one or more corresponding recesses c for said lugs or guides
to enter when putting the coupling together, for the purpose of adjusting the
coupling sections into proper relation with each other and holding the coupling in
place while coupling.
C is a rubber or other elastic packing ring, inserted within the enlarged head of
the female section B, for the entering end of the male section, A of the coupling to
bear against, when closing the coupling.
D is the lever handle-piece for locking and unlocking the coupling.
This handle piece is arranged to run when closed lengthwise of the coupling
upon the one side of it and to partly encircle the same. It is made with two
opposite side ears d d intermediately of its length in extended partial encircling
relation with the coupling and to the extremities of which are pivoted links E, E,
that are connected at their opposite ends to central pivots e e on opposite sides of
the head or meeting end portion of the coupling section A.; said handle piece D is
furthermore constructed, at its inner end, with opposite side hooks or hook shaped
extensions ff, which hooks engage with opposite central side studs or pins g g on
the coupling section B.
To close the coupling, after its two sections A, B, have been brought together,
the hooks ff, of the handle piece D are engaged with the pins g g and said handle

page_text: piece shut down or inward till the pivoted connection 8, 8, of the links E E pass
beyond the culminating point of the links relatively to their pivots e e and the
locking pins g, g, or in other words, beyond a straight line x, x., drawn to centrally
intersect said pivots and pins. In this action, the elastic packing ring C will first
be compressed by the entered portion of the male section A of the coupling, but
afterward, and as the pivoted connections 8 8, of the links pass their culminating
point as described, will slightly yield and serve to hold the handle-piece in its
locked position and the coupling sections securely closed.
To unlock the coupling, it is only necessary to move outward the handle-piece D,
as shown by dotted lines in Figure 1 and to move it so that the hooks ff, will pass
out of the way of the locking pins g g, when or after which the coupling
sections A B may be drawn apart. A single motion of the one hand will serve to
either couple or uncouple the device which will be found to constitute an extremely
simple efficient and quickly acting hose coupling.
Having now particularly described and ascertained the nature of the said
Invention and in what manner the same is to be performed I declare that what I
claim is:―
.
The combination with the male and female sections A, B, of the coupling, of the
elastic packing ring C, the locking pins g, on the one section, the pivots e on the
adjacent section in like central longitudinal line with the coupling as the pins g,
the bandle-piece D constructed with hooks f at its one end for engagement with
said pins, and the links E uniting said handle-piece with the pivots c, for operation
in connection with the elastic ring C, substantially as shown and described.
