I, HENRY LEVICK of Green Hill Tannery, Grantham, in the County of Lincoln,
Tanner, do hereby declare the nature of this invention to be as follows:-
In the present process of tanning the hides are raised by hooks out of the pits
containing the liquor. The use of hooks necessitates the placing of the hides in the
pits with the flesh side downwards, as otherwise, the grain side would be injured, and
even as it is the grain side is often scratched and the leather deteriorated in value.
According to my invention I perform the operations of tanning with the flesh side
upwards whereby a better result is obtained and I dispense altogether with the use of
hooks by providing means for lifting the hides in the pits till they can be reached by
the workman and removed by hand. Usually I employ a rope or ropes for this
purpose, which pass beneath the bottom hide in the pit, one end being fixed and the
other end being brought up out of the pit at one side. By pulling the rope or ropes
all the bides are raised and can be removed one by one by the workman, the rope
being shortened from time to time.
When the pit contains a large number of hides a winch or other convenient
winding apparatus may be employed.
Tan liquor may also be introduced during the removal of the bides from the pits
so as to keep the pit full and relieve the strain on the ropes, and also to enable the
workman to wash off loose bark if any has been placed between the hides.

page_text: J, HENRY LEVICK, of Green Hill Tannery, Grantham, in the County of Lincoln,
Tanner, 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:
In the present process of tanning the hides are raised by hooks out of the pits
containing the liquor. The use of hooks necessitates the placing of the hides in
the pits with the flesh side downwards, as otherwise the grain side would be
injured, and even as it is the grain side is often scratched and the leather deteriorated
in value.
I perform the operations of tanning with the flesh side upwards whereby a better
result is obtained dispensing altogether with the use of hooks by providing means
for lifting the hides in the pits till they can be reached by the workmen and removed
by hand. This has before been attempted but without much practical success.
According to my invention I arrange lifting apparatus as follows:-I employ
ropes which pass beneath the bottom hide in the pit, one end of each rope is fixed
near the top of the pit on one side and the other end is brought up out of the pit
on the other side. By tightening the ropes all the hides are raised and can be
removed one by one by the workmen the ropes being shortened from time to time.
A winch or other convenient winding apparatus is employed to shorten the ropes
when desirable.
Tan liquor may also be introduced during the removal of the hides from the pits
so as to keep the pit full and to enable the workmen to wash off loose bark if any
has been placed between the hides. In place of ropes, cords, bands, or chains might
be employed.
Figure 1 of the annexed drawings shews a plan and Figure 2 a longitudinal vertical
section of tan pits provided with apparatus for carrying out my.invention.
a a are two pits-b is the pile of hides in one of them-cc are ropes, one end of
each is secured to the bar d, and the other end goes to the winch barrel e. As the
hides are removed from the pit the ropes c c are wound up so as to keep the top of
the pile within reach of the workman who is removing the hides.
ff are draining boards on which the hides are laid.
The winch is moveable from pit to pit.
In place of the winch a simple rolfer or bar resting on the side walls of the pit
and turned by hand or hand spikes may be substituted but the winch is more con-
venient when lifting heavy weights,

page_text: 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 :-
1. Raising the hides in the pit as they are being removed by apparatus substantially
as described so that they can be taken one by one by the workmen without the use
of hooks.
2. The combination of apparatus substantially as shown in the drawings annexed.
Dated this 28th day of January 1889.
