I WILLIAM LLOYD WISE of No. 46 Lincolns Inn Fields in the County of Middlesex
Consulting Engineer and Patent Agent do hereby declare the nature of this invention
to be as follows:-
Heretofore, besides engine power, manual power has often been employed to drive
centrifugal machines the requisite rotary motion being imparted to the centrifugal
apparatus with the aid of a hand fly wheel through suitable transmitting gear.
It has been found however by experience, that with such means it is very difficult
for the operator to maintain a constant speed of rotation, and the labor is very
exhausting even if the gearing be as perfectly designed as practicable, so that the
operator has to be relieved at frequent intervals. Thus the cost of labor becomes
considerable and even when employing relays of operators, it is very difficult to
maintain the constant speed of rotation that is necessary to the efficient working of
centrifugal apparatus.
By this invention these disadvantages are obviated rotary motion being imparted to
the centrifugal apparatus by the tread or foot. This mode possesses the great advantage
of enabling an operator to work a centrifugal apparatus for hours at a time without
becoming tired. To this end treadles or a cranked shaft are or is employed whereby
rotary motion is transmitted to the shaft of the centrifugal apparatus through suitable
gearing. Referring to the annexed illustrative drawings Figs. 1 and 2 are eleva-
tions at right angles to one another of an apparatus according to this invention. A is
a centrifugal vessel that may be of any suitable kind. B is intermediate gearing that
may also be of any suitable kind.
Arranged in connection with the latter is a horizontal shaft with two cranks D
provided with sleeves or pedals E.

page_text: The apparatus is arranged so that the operator can sit comfortably whilst working
the machine; he sits on a seat F, steadying himself by means of a handle G, and
works the shaft C with his feet.
The seat is attached to the top of a standard H, the lower end of which is
received into an adjustable foot-piece or base I formed with a bar K having a slot.
A bolt M. that screws into the base plate L passes through the slot, and so enables
the seat to be moved nearer to or further from the crank-shaft C to suit the operator;
when adjusted it is fixed in position by means of the bolt M.
As is well known treadles and pedals have been previously employed for various
purposes; and it is to be noted that this invention does not relate either broadly to the
employment of treadles or pedals for imparting rotary motion, or to any special
construction of treadles or pedals, or any special form of gearing, or special construc-
tion of centrifugal apparatus but has reference to the adaptation and use of treadles
or pedals for working centrifugal apparatus.
Improvements in the Combination of Apparatus with Centrifugal
Machines for the Purpose of Driving the same.
T, WILLIAM LLOYD WISE, of No. 46 Lincolns Inn Fields, in the County of Middlesex,
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 the combination with centrifugal machines and
apparatus for imparting rotary motion thereto by the tread or foot of a seat made for
the operator.
Such seat is made adjustable in relation to the treadle or crankshaft as I will now
describe.
Referring to the illustrative drawings filed with my provisional specification
Figs. 1 and 2 are elevations at right angles to one another of an apparatus according
to this invention.
A is a centrifugal vessel that may be of any suitable kind, B is intermediate
gearing that may also be of any suitable kind. Arranged in connection with
the latter is a horizontal shaft C with two cranks D provided with sleeves or
pedals E.

page_text: The apparatus is arranged so that the operator can sit comfortably whilst working
the machine; he sits on a seat F steadying himself by means of a handle G, and
works the shaft C with his feet.
The seat F is attached to the top of a standard H, the lower end of which is received
into an adjustable foot piece or base I formed with a bar K having a slot. A bolt M
that screws into the base plate L passes through the slot, and so enables the seat F to
be moved nearer to or further from the crankshaft C to suit the operator; when
adjusted it is fixed in position by means of the bolt M. Treadles and pedals have
been previously employed or proposed to be employed for various purposes including
the driving of centrifugal machines and it is to be noted that this invention does not
relate either broadly to the employment of treadles or pedals for imparting rotary
motion, or to any special construction of treadles or pedals, or any special form of
gearing, or special construction of centrifugal apparatus.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what I
claim is :-
Providing in connection with apparatus substantially such as described for imparting
rotary motion to a centrifugal machine by the feet an arrangement and combina-
tion of parts substantially such as described and illustrated in the drawings and
which comprises a seat F whereon the operator can sit in front of the treadle or
crank shaft in relation to which the said seat is made adjustable in the manner
described.
