Improvements in the Method of and in Apparatus for Drying Leather
and the like.

I, ROWLAND MOHUN, of 26, St. Ann's Mount, Burley, Leeds, in the County of
York, Curier, do hereby declare the nature of this invention to be as follows
My invention relates to a method of drying leather after tanning, whereby the
process of drying 18 completed in about one-third the tame required by the ordinary
methods
I employ a circular, octagonal, or other suitable fiame of wood or of any suitable
material, provided with a series of concentric or other bars from which the leather
or skins to be died are suspended.
The sand frame 18 mounted horizontally on a central vertical shaft, which 18
diven by bevel or other suitable gearing so as to revolve the frame
The apparatus is enclosed in a suitable hot-air room, and is preferably driven
from without.
Two or more hurdles or the like may be employed beneath the frame when the
leather is in its wet state, these by coming in contact with the suspended leather
at each revolution of the frame keep the leather flexible
If requined the suspending bars may have suitable gups or hooks pivotted or
attached thereto to grip or hold the leather in the required position.

Improvements in the Method of and in Apparatus for Drying Leather
and the like.
I, ROWLAND MOHUN, of 26, St Ann's Mount, Burley, Leeds, in the County of
York, Cuirier, 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 the drying of leather after the tanning or stuffing
processes, the object being to reduce to a minimum the time required for such
drving process.

page_text: The method I adopt is to revolve the hides, while suspended from or attached
to a suitable frame, within a suitable hot-an chamber.
DESCRIPTION OF DRAWINGS
Fig. 1 is an elevation of the apparatus employed, one half being shown in
section
Fig. 2 18 a plan of Fig 1
In constructing my revolving drying frame I employ a main shaft A mounted
vertically in suitable bearings and duiven preferably from a shaft B by means of
bevel wheels C and D. The said vertical shaft A has a fixed collar E to which
are attached a series of horizontal 1adial arms F, which are enclosed within a
metal hoop or ring G and are supported at then outer ends by connecting aims H.
The said connecting aims H are bolted to a dished collar † on the shaft A, and
ale preferably forked at then outer ends L
The radial arms F are recessed at suitable intervals to receive a series of detacù-
able bars M, which are provided with projecting pins or hooks N from which the
leather to be dried may be 'suspended
To the outer and inner ends of each of the said radial arms F are attached
vertical bars P, R, having hooks S or other equivalent device for supporting and
adjusting a detachable radial arm Fl
These detachable arms F¹ are also recessed to receive a second series of detachable
suspending bars M' having hooks N¹
Small hides may be suspended from the top bars M and attached at then lower
ends to the corresponding lower bars or to the radial aims F1 by means of
suitable hooks. When much larger hides are being treated the lower frame may
he removed
If required each of the radial aims F and F may be provided with a sliding
locking bar T, recessed on its under side, to lock the suspending bars M and M
in position when the machine is working, the said bai having a limited longi-
tudinal movement on the said aim (80 as to release the bais), and working in
guides V (as shown in the lower frame in Fig 1) or within the forked end Ĺ of
the connecting arms H on the top frame
If desired a loose hurdle with a revolving adjustable cross-bai may be employel
to keep the leather flexible, the said hundle being placel under the frame.
between the vertical bars P and R, so as to come into contact with the suspended
hides at each revolution of the fiame
The cross-bar of the said hurdle is preferably slightly tapered or conical and by
revolving on its axis avoids the tendency to diag the hides from the suspending
bara
The hot-air chamber in which the apparatus is enclosed is preferably con-
stiucted in corrugated iron, with suitable openings to allow a free circulation of air,
the machine serving as its own fan
The drying frame may be constructed in various sizes to suit the class and
amount of leather to be treated. In the accompanying drawings the frame 18
shown with eight radial aims F, but in larger machines twelve or sixteen may be
employed with advantage.
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 The employment, as a means of rapidly drying leather and hides, of a revolv-
ing frame having suitable means of suspension or attachment, the said frame being
preferably enclosed in a suitably heated chamber, substantially as shown and
described
2. The combination with the means described and claimed for drying leath
and the like, of the aims or bars F1. M. hooka 8. and vertical bars P R aanged

and illustrated.
