PROVISIONAL SPECIFICATION.
An Improved Fastening or Coupling.
I ROBERT AUBREY of 194 Kennington Road Kennington in the County of Surrey
Gymnast do hereby declare the nature of this invention to be as follows:-
--
This invention relates to an improved fastening or coupling for various purposes
such as for railway couplings harness boating tackle etcetera and has for its object to
provide a fastening or coupling-for the aforesaid purposes or for any other purposes
to which it can or may be applied-which can be easily and readily detached in a
moment while at the same time being perfectly secure and in no way liable to detach
itself the greater the strain on the coupling the more secure it becomes.
For this purpose my improved coupling or fastening is constructed as follows:-
One part of the coupling which I will call the "female" part consists of a tube
having an eye hook ring or other suitable means provided at its outer end for attaching
to one of the objects to be coupled and on this tube are formed or secured lugs cars
or trunnions in which a lever is mounted on a pin and having a cam surface or
projection on its inner end which when the outer end of the lever is pulled over
projects through into the interior of the tube or "female" part of the coupling.
The other or "male" part of the coupling consists of a straight pin which at its
outer end has also an eye hook ring or other suitable means provided for attaching to
the second object to be coupled or fastened and the other end of this pin or male part
is inserted in the tube or female part the aforesaid lever is then pulled over so that the
projection thereon projects through into the interior of the tube and enters a slot or
recess cut or formed in the "male" part to receive same and thus the two parts are
securely and rigidly coupled together.
By simply pulling the lever back again-and the greatest strain on the coupling
does not prevent this-the two parts are immediately and readily released.
If desired a suitable spring (for instance an india rubber band) may be used to
prevent the releasing lever being moved by jarring or otherwise.

COMPLETE SPECIFICATION.
An Improved Fastening or Coupling.
I ROBERT AUBREY of 194 Kennington Road Kennington in the County of Surrey
Gymnast 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 :-
:-
This invention relates to an improved fastening or coupling for various purposes
such as for railway couplings harness boating tackle etcetera and has for its object to
provide a fastening or coupling-for the aforesaid purposes or for any purpose or
purposes to which it can or may be applied-which can be easily and readily detached
while at the same time being strong secure and in no way liable to detach itself-the
greater the strain on the coupling the more secure it becomes.
For this purpose my improved coupling or fastening is constructed as follows :—
One part of the coupling which I will call the "female" part consists of a tube or
socket having
an eye hook ring buckle or other suitable means provided at its outer
end for attaching to one of the objects to be coupled and on this female part are
formed or secured lugs ears or trunnions in which a lever is mounted on a pin and

page_text: "
having an eccentric surface or projection on its inner end which-when the outer
end of the lever is pulled over-projects through into the interior of the "female"
part of the coupling.
The other or "male" part of the coupling at its outer end has also an eye hook
ring or other suitable means provided for attaching to the second object to be coupled
or fastened and the other end of this "male" part is inserted in the female part the
aforesaid lever is then pulled over so that the projection thereon projects through into
the interior of the socket and enters a slot or recess cut or formed in the "male" part
to receive same and thus the two parts are securely and rigidly coupled together.
By simply pulling the lever back again-and strain on the coupling does not
prevent this the two parts are immediately and readily released.
If desired a suitable spring (for instance an india rubber band) may be used to
prevent the releasing lever being unintentionally moved by jarring or otherwise.
The male and female parts that is the stem and socket of my improved coupling
may both be made correspondingly round flat oval or of other suitable form in cross
section and either straight wedge shaped curved or of other convenient form
longitudinally (according to the purpose to which such coupling is to be applied) the
locking lever being formed in a corresponding manner.
And in order that my present invention may be easily understood and readily
carried into practice 1 will proceed to describe the same with reference to the drawings
hereunto annexed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 shows an exterior longitudinal side view of my improved coupling-the
case illustrated being a straight coupling the male and female parts being round in
cross section.
Figure 2 is an end view of same.
Figure 3 is same view as Figure 1 with parts removed or broken away to show the
interior of the coupling.
Figure 4 is a cross section on liue y Figure 3.
Figure 5 is similar view to Figure 3 but with the locking lever a raised to release
the parts.
Figure 6 shows the parts released and partially withdrawn.
The locking lever a turns on and has its fulcrum on the pin or axis 6 in the
trunnions or bearings c formed on or secured to the socket or "female" part d the
interior of which latter is in the case illustrated formed cylindrical.
The inner end of the lever a is forined nearly flat at the point e and having a pro-
jecting or eccentric part which latter part when the lever a is pulled over (or shut
down as shown in Figures 1 and 3) projects into the interior of the passage in the
female part d.
g is the stem or male part corresponding in form with the interior of the socket d
and having a groove slot or recess i formed therein into which the eccentric or
projecting part of the locking lever a enters and thereby securely holds the two
parts d and g together.
jis an india rubber band which may be used to prevent unintentional opening of
the lever a by jarring or otherwise.
m m are eyes for connecting up to the two parts to be coupled-but these parts m m
form no part of my invention as any other suitable form of connection may be used
if desired.
In the case of a cylindrical coupling as illustrated a tongue or projection o on the
part g is provided to enter a corresponding recess p cut in the tube d to receive any
torsional strain that may be put on the coupling which otherwise would be thrown on
the point of the eccentric locking lever; or an annular groove all round the stem g
may be formed at the point i so that the coupling will act which ever way the round
pin or stem g is inserted-the tongue o and recess p being dispensed with. When the
parts d and g are of any other section than round such tongue o and corresponding
recess would not be found necessary.

page_text: The recess in the part o may be either a slot formed of the exact size to receive
the eccentric surface fas shown in Figure 4 or it may be a slot or groove right across
the part 9 or if it is desired that this coupling be capable of rotating so as to form a
swivel joint then such groove is formed all round the stem 9 as above and the
shoulder o and recess p are dispensed with.
To make a coupling for harness or such like purposes in accordance with my present
invention the lever a with eccentric surface thereon would be of much the same
form and mounted and arranged to act much in the same manner as in the coupling
illustrated but the stem part would be made of a thin plate having a recess cut or
formed therein to receive the eccentric surface of the locking lever as before which
thin flat stem enters a corresponding thin flat socket and the locking lever mounted
and arranged to act (as before described) upon one side edge of the latter so that the
projecting surface f serves to lock the two parts securely together.
In like manner this lever a can be modified and adapted to act in a similar
manner with other shapes or forms of couplings according to the purposes for which
such couplings or fastenings are required.
It will be obvious that such a coupling or fastening can be adapted in various ways
to numerous purposes and the cases 1 have illustrated and described will enable such
modifications and adaptation to be readily carried out as desired so long as the
direct acting locking lever (which constitutes the main feature of my invention) is
retained.
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 coupling or fastening consisting of a locking and releasing lever a having its
fulcrum on an axis or pin 6 in bearings or trunnions c which latter are mounted on
the socket part d of the coupling with such lever acting directly over the two parts
d and 9 of the coupling and having a surface or projection f at the inner end thereof
eccentric to the said pin or axis b so that when said lever a is pulled over such pro-
jecting surface will enter a slot or recess i in the second or stem part 9 of the
coupling and thus securely hold the two said parts d and g together the several parts
being arranged and combined substantially in the manner and for the purposes
hereinbefore described and illustrated in the drawings hereunto annexed.
2. In a coupling or fastening I claim the lever a having the surface ƒ on its inner
end mounted and arranged to act substantially in the manner and for the purposes
hereinbefore set forth.
3. A coupling or fastening, consisting of a socket part having bearings or trunnions
arranged thereon, a pin or axis in such bearings, a lever turning on such pin and
baving its fulcrum thereon, a projecting surface on one side of the inner end of such
lever which projects through the side and partly into the interior of said socket when
the outer end of such lever is pulled over, a stem part which corresponds with and
fits into the socket part of the coupling, and a slot or recess formed in the inner end
of such stem to receive the projecting surface of such lever so as to lock the two parts
securely together all substantially as and for the purposes set forth.
