My invention relates to an improved construction of attachment device for
harness and the like, which I will describe with reference to the accompanying
drawing, in which Fig. 1 shews a plan of the one part of the device, Fig. 2 shews
a plan of the other part, Fig. 3 shews a sectional side view of the two parts

parts turned relatively to each other into the position for detaching them.
The device consists firstly of a loop or chain link M having a rounded or
circular part and a narrow elongated part, the opening of which constitutes a
slot secondly of a hook shaped catch or key C shewn in plan at Fig. 2 and in
sectional side view at Fig. 3, consisting of a spherical or rounded head, adapted
to pass through the circular opening of the link M and to slide with its adjoining
neck along the slotted part of the link. From the neck the stem of the hook
is curved downward so that its base is at right angles to the head. When the
hook has been engaged with the link M as described and as shewn at Fig. 3,
it will be seen that the two parts of the attachment device are securely connected
to each other.

The two parts of the attachment device are each connected to the harness
traces, or the like, by means of a connecting ring or shackle A, connected thereto
by a swivel bolt or pin T, so that no twist can be transmitted through the
attachment device to the harness trace.
In order to prevent the hook or key C from becoming accidentally disengaged
from the link M by sliding back to the circular opening thereto when the traces
are slack, a safety device is employed, which consists in forming the swivel pin T
with a conical head projecting into the circular opening of M while in the
spherical head of the hook I form a corresponding V shaped notch E at the side
thereof, that is to say, at a right or other angle to the direction DD¹ of the
traces as at Fig. 4.
Thus if the key C slides straight back in the slot of M it is prevented by the
swivel head T from entering sufficiently into the circular opening to become dis-
engaged therefrom, and it is only when the key is turned round to a right or
other angled position, so as to cause the notch E to fit onto the head of T, as
shewn at Fig. 4, that the head can pass out of the circular opening.
When a pull is exerted upon the traces, the two parts M and C are in the
position shewn at Fig. 3 and 5, and are consequently effectually locked together.

page_text: Improved Attachment Device for Harness and the like.
I, PIERRE VAN EECKHOUT, of Rue Van Eyck 10, Brussels, Belgium, Captain
of Artillery, 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:-
My invention relates to an improved construction of attachment device for
harness and the like, which I will describe with reference to the drawing accom-
panying my Provisional Specification, in which Fig. 1 shews a plan of the one
part of the device, Fig. 2 shews a plan of the other part, Fig. 3 shews a sectional
side view of the two parts engaged with each other, Fig. 5 shews a plan of the
same, and Fig. 4 shews the parts turned relatively to each other into the position
for detaching them.
The device consists firstly of a loop or chain link M having a rounded or
circular part and a narrow elongated part, the opening of which constitutes a
slot secondly of a hook shaped catch or key C shewn in plan at Fig. 2 and in
sectional side view at Fig. 3, consisting of a spherical or rounded head, adapted
to pass through the circular opening of the link M and to slide with its adjoining
neck along the slotted part of the link. From the neck the stem of the hook
is curved downward so that its base is at right angles to the head. When the
hook has been engaged with the link M. as described and as shewn at Fig. 3,
it will be seen that the two parts of the attachment device are securely connected
to each other.
The two parts of the attachment device are each connected to the harness
traces, or the like, by means of a connecting ring or shackle A, connected thereto
by a swivel bolt or pin T, so that no twist can be transmitted through the
attachment device to the harness trace.
In order to prevent the hook or key C from becoming accidentally disengaged
from the link M by sliding back to the circular opening thereto when the traces
are slack, a safety device is employed, which consists in forming the swivel pin T
with a conical head projecting into the circular opening of M while in the
spherical head of the hook I form a corresponding V shaped notch E at the side
thereof, that is to say, at a right or other angle to the direction DD¹ of the
traces as at Fig. 4.
Thus if the key C slides straight back in the slot of M it is prevented by the
swivel head T from entering sufficiently into the circular opening to become dis-
engaged therefrom, and it is only when the key is turned round to a right or
other angled position, so as to cause the notch E to fit onto the head of T, as
shewn at Fig. 4, that the head can pass out of the circular opening.
When a pull is exerted upon the traces, the two parts M and C are in the
position shewn at Figs. and 5, and are consequently effectually locked together.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is-
An attachment device for harness and the like, consisting of the combination
of a link M having a narrow opening or slot terminating in a wider opening,
and a key or hook C having an enlarged head adapted to pass through the en-
larged opening of the link, but not through the narrow part, said head having
a notch E situated at an angle to the direction of the hook, while the enlarged
hole of the link M has a projection T that will prevent the head of the hook from

page_text: passing through such enlarged hole unless the head is turned into an angular
position in which the projection T engages with the notch E, substantially as
described.
