PROVISIONAL SPECIFICATION.
Improvements in or relating to Portable Punkahs.
We SAMUEL ROBERT BAILDON of 1 Whitefriars Street, and JAMES KERSHAW of
97 Wood Street, City of London, Gentlemen, do hereby declare the nature of this
invention to be as follows:-
The object of this invention is, to construct or arrange a frame by which a punkah
can be supported either for a to and fro or rotatory action and capable of being driven
by hand or foot power.
The apparatus is of a portable character and can be moved from place to place such
as from a room to a garden or otherwise.
The apparatus consists of a couple of uprights braced by suitable rods or bars at the
desired distance apart said uprights having splayed out or other feet, the ends of which
may be pointed for the better gripping the ground and to prevent oscillation while the
fan or punkah is being worked.
The punkah proper is affixed to a cross bar near the upper part of the uprights and
by crank, pulley, or the like, motion can be given to it by pull or endless cord operated
by hand by a person sitting under the punkali or by an attendant close to the punkah
or at a distance therefrom in which case the punkah and its crank and the crank or
driver wheel of the distant frame could balance each other and thus reduce labour to a
minimum whether the motion be by the hand or from a pedal.

COMPLETE SPECIFICATION.
Improvements in or relating to Portable Punkahs.
We, SAMUEL ROBERT BAILDON, of 1 Whitefriars Street, and JAMES KERSHAW, of
97 Wood Street, City of London, Gentlemen, 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:-
The object of this invention is to construct or arrange a frame by which a punkah
can be supported, either for a to and fro, or rotatory action, and capable of being driven
by hand, or foot power.
The apparatus is of a portable character and can be moved from place to place, such
as from a room to a garden, or otherwise.
The apparatus consists of a couple of uprights braced by suitable rods or bars at
the desired distance apart, said uprights having splayed out or other feet, the ends of
which may be pointed for the better gripping the ground and to prevent oscillation
while the frame or punkah is being worked.
The punkah proper is affixed to a cross bar near the upper part of the uprights and
by crank, pulley, or the like, motion can be given to it by puil or endless cord operated
by hand by a person sitting under the punkah, or by an attendant close to the punkah,
or at a distance therefrom, in which case, the punkah and its crank and the crank or
driver wheel of the distant frame could balance each other and thus reduce labour to a
minimum, whether the motion be by the hand, or from a pedal.
The invention will be clearly understood by the annexed drawings, in which
Figure 1 is a perspective elevation of a rotatable punkab provided with a single fan
and a balance weight and workable from one of the uprights.

motion from a pull cord.

motion by a swing weighted lever like a pendulum.

C, C. tie bars.
D, the punkah.
E, winch, or other driving gear.
According to Figure 1, we rotate the punkah by the handle E and endless
cord E.
The punkah, at Figure 2, is driven by alternately pulling at the cord ends, each
cord being wound on and off the driver wheel.
The seats may be ordinary chairs, or folding chairs, or deck seats can be placed
under the punkah and used by the person while working the punkah.
The working of the punkah, shown at Figure 4, can also be effected in the same
manner if the driver frame be placed close enough and the cord be of reduced length
to that shown but we purpose placing the driver frame at a distance to be operated by
an attendant by hand or pedal.
According to Figure 3, the punkah frame and seat is in one structure, and for this
purpose we hinge the seat back F to a lower tie bar, and also the scat G, to the front
corners of which, we joint two rods or links H, these having other links´I, I, jointed
to them to support a foot board J.
These jointed parts can all be folded towards the uprights A, A, and be fastened in
any convenient manner, and the simplest way would be to use the two short
pieces K, K, which temporarily hold the seat back at the proper inclination.
Having now particularly described and ascertained the nature of this inven
tion and in what manner the same is to be performed we declare that what we
claim is :-
The portable punkahs shown in the annexed drawings, and the methods of operating
hem, substantially as described.
em, substantially as described.
