page_text: and each can be driven independant of the other, by suitably arranged stopping
and starting gear.
By driving the said shafts as aforementioned I am enabled to dispense with
gearing wheels consequently reducing the number of the working parts on the
machine, making it to run smoother and less noisely, and enabling the attendant
to stop it with greater precision.
On the knives shaft is a small spur wheel K which communicates motion through
the train L. M. N-the axles of which are fixed to the bracket O-thence to the
wheel P fixed to the shaft of the lower feeding roller G.
The arrangement for raising and lowering the upper feeding roller H. is as
follows, the links R-there being a similar arrangement on each side of the
machine-connect from the ends of the said roller shaft to pins S to which pins
also connect one end of a second link T, the other ends of the said links Tare
secured to a fulcrum shaft U. supported at each end of the machine in brackets V
which are secured to the sides of the slot F. A sector plate W provided with
suitable notches is secured to either of the brackets V; one end of a locking lever X
is secured to the fulcrum shaft U.
When it is required to raise the roller H-which must be done in order to place
a fresh skin or leather-the attendant releases the catch lever Y with his fingers,
then moves the locking lever X from him, thus raising the roller H; he then
secures the same in this position by allowing the catch lever to fall into one of the
notches in the sector plate, which enables him to lay the skin to be ground.flat
upon the lower roller, the roller H is then lowered so as to grip the skin between
the two, and is then locked. This arrangement is more efficient and handier for
the attendant than the ones heretofore employed.

The working of the machine is somewhat similar to the one described in the
specification of myself and others numbered 5459 of 1885.
The attendant on the front side of machine first raises the upper feeding roller
as herein before described, lays flat, and secures one end of the skin between the
feeding rollers the knives are then put into motion by the attendant pressing his
foot upon a treadle communicating with the. belt fork, the other end of the skin is
held on the feeding board Z so as to keep it flat and straight while the knives are
operating upon it; the front or neck end is received by the attendants at the back
of the machine who conduct it over the facing or fluffing roller. When the skin
has passed over in this manner it is turned round and the operation repeated.
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
i
:
First. The arrangement for raising and lowering the upper feeding roller con-
sisting of links (R and T) of the fulcrum shaft (U) fixed as aforementioned of a
locking lever (X) fixed to the said shaft provided with a catch lever (Y.) and of a
notched sector plate (W) all substantially as described and illustrated in the
accompanying sheet of Drawings.
k
Second. An arrangement of communicating motion to the knives and facing
roller shafts of a machine for grounding and softening skins or leathers, and the
driving of the said shafts independently, all substantially as described.
