The bed or table L and trestle M are mounted on elastic cushions or springs, as
shown, in order to moderate the action of the pressure roller, and its upper surface
is shaped to correspond approximately with the direction of movement or path of
the roller K. The workman stands in front of the upper end N of the bed or
table.
The above described arrangement for supporting and actuating the roller K
may be modified by substituting a crank for the flywheel on one side of the
machine; or the fly wheel connecting rod F and suspension rod G on one side of
the machine may be dispensed with, in which case the levers J are replaced by a
fork which constitutes a bearing for the roller K and is connected to a single
suspension rod G.

Improvements in Shagreening Machines.
A communication from abroad by WILHELM HEINRICH EBERHARD BRANDE, of
Hamburg, Germany, Merchant.
I, WILLIAM LLOYD WISE of No. 46 Lincoln's Inn Fields, in the County of
London, Consulting Engineer and Patent Agent, 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 :-
This invention has reference to improvements in shagreening machines as I will
[Price 8d.]

page_text: now proceed to explain by aid of the drawings left with my Provisional Specification
in which
Fig. 1 is a side elevation,
Fig. 2 a front elevation and
Fig. 3 a plan of such a machine.
Supported in bearings which rest on standards or frames A., and driven from the
belt pulley B is a shaft C, on each end of which is fixed a fly wheel D.
To a pin E fixed to one of the spokes of each fly wheel is connected one end of
a rod the other end of which is connected to a lever J. The two levers Jarc
jointed to the lower ends of two suspension rods G the upper ends of which are
fixed to a rock shaft supported in bearings attached to the ceiling of the work-
shop. The levers are journalled on pins a provided in the suspension rods G,
and carry between their lower ends the pressing or working roller K.
The leather to be shagreened or treated by the roller K is spread out on a bed
or table Larranged upon a trestle M below the roller K which is passed during
the operation of the machine to and fro in a swinging manner over the bed or
table L so as to act upon a certain width or strip of the leather thereon.
The bed or table and trestle M. are mounted on elastic cushions or springs as
shewn in order to moderate the action of the pressure roller, and its upper surface
is shaped to correspond approximately with the direction of movement or path of
the roller K.
At each revolution of the flywheels D the roller K describes an approximately
elliptical path, which allows of the leather being shifted on the bed or table during
the travel of the roller through the air, and also, when the flywheels are revolving
continuously, allows the roller to move over the leather in one direction only,
preferably, from top to bottom. The workman stands in front of the upper end N
of the bed or table.
The above described arrangement for supporting and actuating the roller K may
be modified by substituting a crank for the flywheel on one side of the machine:
or the flywheel, connecting rod F and suspension rods on one side of the machine
may be dispensed with, in which case the levers J are replaced by a fork which
• constitutes a bearing for the roller K and is connected to a single suspension
rod G.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed declare that what I
claim is :-
:-
1. A shagreening machine, comprising a roller K mounted in levers and to
which a swinging motion is imparted by means of suspension rods G pivotted to
brackets or hangers attached to the ceiling H of the workshop and actuated by
draw rods F cach driven from a fly wheel or crank, and an elastically mounted
table L the upper surface of which is shaped to correspond with the direction of
movement or path of the roller, and upon which the leather to be treated is spread
so as to be acted upon by said roller substantially as described and shewn in the
drawings.
2. The modified construction of machine in which the roller referred to in the
preceding claim is mounted in a fork that is supported by a single suspension rod
pivotted in a bracket or hanger attached to the ceiling H of the workshop, and is
actuated by one fly wheel or crank and connecting rod substantially as described.
Dated this 7th day of March 1892.
