An Improved Slip Hook for Instantly Releasing a Fallen Horse
from the Shafts or Pole of a Waggon or Cart.
I, FREDERICK SHEPHERD, of 53 Lafone Street, Horsleydown, in the County
of Surrey, Smith and Farrier, do hereby declare the nature of this invention and
n what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:—
This invention has reference to improvements in slip hooks constructed as
described in the Specification of Letters Patent No. 13,609 A.D. 1889, granted to
me. The long hook, therein described, is extended beyond the pivot to partially
embrace the link of the chain to which the apparatus is, for the time being,
fastened. By this means the strain is put upon the pivot-end of the hook, which
is formed to bear against the box, or frame and thus relieves the pivot of the
strain when the hook is closed.
The V spring by means of which the hook is sprung open on the release of the
sliding catch is made to bear upon the said extension of the long hook instead of its
longer end.
The apparatus is made of five pieces, i.e. the box or frame, sliding catch, hook,
and two V springs. The box is hollow and formed of two pieces fixed together by
three screws.
The hook is made very long and hardened at the hole through
very slight.
which it is pivotted to the box with a steel pivot, so that the wear
At the free end of the hook is formed a catch, which, when the hook is closed
meets with the said sliding catch which is held firmly and securely in position by
one of the V springs.
And in order that my invention may be more fully understood and carried into
practice, I will now proceed to describe the same with reference to the accom-
panying explanatory sheet of drawings in all the figures of which the same parts
are marked with similar reference letters.

Figures 1 and 3 shew the apparatus with the top plate 6 of the box a removed,
and with the hook e closed and open respectively; in the latter figure the sliding
catch d is shewn drawn back to release the hook c. Figure 2 shews the top plate b
in position and the manner in which it embraces the extended end of the hook c
so that the pivot is relieved of all strain, which strain is thrown on the said
extension g and the curved ends of the plate b and box a, when the hook is closed.

The hook-opening spring e is arranged to bear upon the hook-extension
suitably shaped for the purpose. The spring fis employed to actuate the sliding
catch d.

The box is provided with an opening on each side to allow of the insertion of a
finger into a hole in the sliding catch d for the purpose of withdrawing it from
engagement with the hook, which is then instantly released.
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
