PROVISIONAL SPECIFICATION.
Improved Apparatus for Engaging and Slipping Chains, Ropes, and
the like, and for all similar purposes.
I DENNIS HILL WILLEY, of Tynemouth Villa, Lodge Road, Southampton, in
the County of Hampshire, Engineer, do hereby declare the nature of this invention
to be as follows:-
My invention relates to improvements in the form and arrangement of slip
fittings, and the object of my invention is to provide a simple and effective apparatus
for use in temporarily attaching the ends, or parts, of chains, ropes, and the like, in
such a manner as will admit of their being readily connected, and disconnected
almost instantaneously.
1 attain this object by means of the form and arrangement, or similar thereto, of
the parts of an apparatus hereinafter described.
In making a complete apparatus according to one form or modification of my
invention, I first provide a fitting with a forged or cast shank of suitable length,
one end of same shaped into an eye, or hook, and the other into two palms, or plates
of approximately triangular shape, joined at the apex to the shank, and with a
space between them, thus forming a fork, or jaw.
At the two angles or corners at the base of the triangular shaped plates, I
provide and fit arms pivoting on pins passing through the ends of same and the jaw,
the form of the arms may be best described perhaps as that of a shank, or handle
ending in, or connected to, a disc and it is through the discs that the pins pass, and
it is noted in a position out of centre, thus when the shanks or handles connected
to the discs are actuated the latter have an eccentric motion consequently by placing
the handles in a given position the peripheries of the discs are brought together,
and when moved in the opposite direction separated; in other words the opening
between the jaws in a line with the pins upon which the discs pivot, is increased, or
decreased, according to the position in which the disc handles are placed.
Further I provide as a separate fitting an eyebolt, or hook, the end of the shank
of same opposite the eye being probably pear shaped.
To connect this eyebolt to the other part of the fitting it is first necessary to
bring the handles of the pivoted arms into the disengaged position, viz.-in a line
with the shank of that part of the fitting hereinbefore first described, but in the
opposite direction to same, the pear shaped end of the eyebolt or hook fitting is
then passed into the fork or jaw and between the discs, the handles are then returned
to the engaged position, which is one parallel and close to the shank of that part of
the fitting hereinbefore first described, and they the handles can be secured to the
shank by a mousing, or similar arrangement if desired, but it may not be necessary
to do so.
When the arms are in this, the engaged position, the pear shaped end of the
eyebolt is locked within the jaws of the fitting between, and by the discs, by reason
of the periphery of same being brought closer together than when in the disengaged
position hereinbefore described..
It is the eye, or hook, of one or both of the fittings forming the complete
apparatus that is connected to the ends or parts of the chain, or rope, that it is
desired to slip.
My invention essentially consists in the arrangement whereby, the eyebolt or
hook, provided with the pear shaped end, is locked within the jaw of the other part
of the fitting by means of the disc shaped part of the pivoted arms engaging with
the pear shaped end when the handles are brought into a given position, and
consequently when their position is reversed, released almost instantaneously, and

page_text: thereby the chains, or their equivalent, which the slip apparatus connects, in
manner hereinbefore substantially described.

COMPLETE SPECIFICATION.
Improved Apparatus for Engaging and Slipping Chains, Ropes, and
the like, and for all similar purposes.
I DENNIS HILL WILLEY of Tynemouth Villa, Lodge Road, Southampton, in
the County of Hampshire, 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 :-
My invention relates to improvements in the form of slip fittings, or couplings,
and the object of my invention is to provide a simple and effective apparatus for
use in temporarily attaching the ends, or parts, of chains, ropes, rods, and the like,
in such a manner as will admit of their being easily connected and disconnected
almost instantly, but will not detach the same unless it is so desired.
I attain this object by constructing my improved apparatus or coupling in the
following manner, or similar thereto.
Referring to the accompanying drawings which serve to illustrate my invention
Figs. 1, 2, 3, show respectively in outside elevation, plan, and sectional plan, my
complete slip fitting or coupling when in the engaged position and
Figs. 4, 5, 6, the same respectively in elevation, plan, and sectional plan, when
in the disengaged position, and ready for immediate engagement.
Figs. 7, and 8, are sectional plans illustrating more especially a modification in
the form at 1, of that part of the fitting lettered, in the other views.
Fig. 9, is an end view at 1, 1.
The same letters of reference indicate corresponding parts in all the figures.
The complete apparatus consists of two separate parts or fittings A, and B, and
I shall hereinafter refer to the part A, as the female fitting and the part B, as the
male fitting.
The female fitting is a forging, or casting having a shank or stem, which
finishes at one end in an eye or hook c, (or in any other form convenient for the
attachment of ropes, or their equivalent,) and at the other end in a fork or jaw d,
or recess of any other suitable form.
Between the jaw I fit two handles or lever arms e, e, or e¹, e¹, pivoting at the
end f, or f, on a pin k, passing through same, and the jaw, the form of the arms
where pivoted may be either that shewn at f, f, or f¹,, as preferred, or of any
other suitable shape provided the result as herein described is attained.
The pins k, k, upon which the lever arms pivot pass through the end f,f, or f³,ƒ³,
of each arm where pivoted-out of centre, whereby an eccentric, or cam motion is
imparted to the lever arms when actuated.
The male fitting B, is formed at one end into an eye or hook (or into any suitable
shape convenient for the attachment of ropes or their equivalent) and at the other
endi, (namely that part which is inserted in the female fitting A,) into a form
which may be, and is shewn of approximately pear shape, the cross section being
either round, rectangular, or oval, if of round cross section the male fitting could
swivel in the female fitting.
When connecting up the apparatus the end i, of the male fitting is inserted
between the jaw or recess d, of the female fitting A, and the lever arms e, e, or e¹, e¹;
and the latter are then pulled round into the position as shewn at Figs. 1, 2, 3,
and 8, whereby the end i, of the male fitting is secured in the female fitting by the
ends f, f, or ff, of the lever arms e, e, or e¹, e¹.
2

page_text: It is only necessary to reverse this position of the lever arms (that is to place
them in position as shewn at Figs. 4, 5, 6, and 7,) to release the male fitting B,
from the female fitting A, and thereby the connections that may be attached to the
ends c, h, of the male and female fittings.
The handles or lever arms may be secured in the engaged position if desired by
a suitable mousing j, and further, in the disengaged position (see Figs. 4, 5, 6,
and 7) the lever arms cannot come closer together than a distance at least equal to
the greatest size or diameter of the end i, of the male fitting B, as the travel of the
lever arms in that direction is limited by stops p, p, p, p, formed by slightly
recessing the inside part of the jaw d, as shewn at 7, 7, 7, 7', and with which stops
the ends, or f, f, of the lever arms, come in contact when the arms are pulled
over to the disengaged position.
It is noted that even should one of the lever arms e, e, or e', el be accidently
brought into the disengaged position, the other lever arm, if kept in the engaged
position, will still hold, the male fitting B, within the female fitting A, as the
distance between the pivoted ends of the lever arms is even then close enough to
keep the male fitting secured between them.
I do not confine myself to the exact shape as shewn, either of the male or female
fittings of my apparatus, the same may vary provided the essential features of my
invention (as herein before described and illustrated in accompanying drawings) are
retained, which more especially consist in a pair of lever arms, the ends of which
pivot in a suitable fitting out of centre whereby the distance between the ends of
the arms e, e, or ele, at f, f, or flf in a line with the centres upon which they
pivot, increases or decreases, according to the position in which the lever arms are
placed.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is :-
1st. The improved apparatus designed for temporarily attaching and securing,
and subsequently letting go, or slipping, the ends, or parts of chains, ropes and the
like, as hereinbefore substantially described, and illustrated in accompanying
drawing.
2nd. In an engaging and slipping apparatus two lever arms e, e, or e¹, e¹, working
in the jaw or recess d, of a female fitting A, or similar thereto, the said lever arms
pivoting on pins k, k, which pass through the ends f, or f¹, of each lever arm out of
centre of same, and through the jaw d, the said lever ends being arranged and
adapted to engage with and lock within the female fitting A, a male fitting B, or
similar thereto, when the latter is passed into or between the jaw or recess d, and
they (the lever arms) are brought into the engaged position, the male fitting B,
being immediately released from the female fitting A, upon reversing the position
of arms, in manner hereinbefore described and illustrated in accompanying
drawing.
3rd. In an engaging and slipping apparatus I claim the two levers e, e, or e¹, e¹,
forming part of a fitting A, so mounted and arranged that should one of the said
lever arms be accidentally brought into the disengaged position, the other still securely
holds the fitting B, in the engaged position, as herein before substantially described
and illustrated in accompanying drawing.
