SQUIRE BROADBENT and SQUIRE BROADBENT the younger, of Tong, in the
County of York, Colliery Proprietors IMPROVEMENTS IN THE METHOD OF AND
APPARATUS FOR THE GENERATION AND AUGMENTATION OF POWER FOR
MANUFACTURING PURPOSES
This invention has for its object the generation of motive power by force of
steam, wind or water at a much less cost than hitherto.
We accomplish our object by forming one or more grooves in the periphery of
a wheel and fit and secure within and for the full width of each groove a number
of teeth or projections formed somewhat in the same manner as ratchet. The
periphery and sides of the flanges forming the grooves are turned perfectly true
and covered for a certain distance with a curved plate made to accurately fit the
turned part of the wheel and flanges. To the curved plate one or more pipes are
connected, also as many sliding valves as there are pipes: this sliding valve (or
valves) rises and falls parallel to the face of the teeth, through the curved plate,
such motion being imparted by the valve being kept tight against the inclined
planes of the teeth by pressure of spiral or other springs secured to curved plate,
and when the pressure of steam, air or water is admitted the same acts upon the
straight side of the ratchet tooth or teeth, the sliding valve keeping the pressure
from the inclined portion, by which means the wheel is made to rotate.

County of York, Colliery Proprietors IMPROVEMENTS IN THE METHOD OF AND
APPARATUS FOR THE GENERATION AND AUGMENTATION OF POWER FOR
MANUFACTURING PURPOSES
.
This invention has for its object the construction of an apparatus for the
utilisation of power contained in steam, compressed air, or water, and this object
we attain by constructing a wheel the periphery of which is fitted with a series of
teeth and in combination with the wheel is one or more valves which admit and
cut off the pressure to and from the teeth.
In the case of having high pressure steam at command, we can utilise the
exhaust from the first inlet either to other teeth or projections, on the. same wheel,
or carry the exhaust steam to other wheels; thus we obtain the advantages of
compound engines in the manner as fully hereinafter described.
The wheels, grooves, teeth. or projections; covers and valves vary in size,
according to the power required to give off.
In order that our invention may be better understood, we will proceed to
describe the same by reference to the accompanying drawings in which like letters
indicate like parts.
Figure 1 represents the boss and such portions of a wheel as are necessary to
shew our invention. Figuro 2 is a section through a portion of a wheel and
valves drawn to a larger scale than is Figure 1. Figures 3 and 4 are cross sections
of a pair of wheels placed side by side the latter through line A A.
The wheel is mounted upon a shaft supported by journals in the ordinary
manner the shields B of the wheel are turned true inside over the periphery and
a portion of the outside: between the said shields are fitted and secured a number
of teeth T, and covering for a certain distance the wheel and teeth, is a curved
bracket C supported by beams D D. Between the bracket and the wheel we place
packing plates E which are adjusted by screws S to fit the periphery and sides of
the shields B.
Secured to the bracket C is valve casing F to which the pressure pipe G is
connected and made tight by means of stuffing box and gland H. Around the
lower portion of this pipe is mounted the sliding valve J the bottom part of which
is made angular to fit the incline of the teeth T, and the sides of the valve to fit
between the shields B. The valve J is kept in contact with the teeth, by means
of a spiral spring placed between the top of the sliding valve and a collar on the
pipe G or the valve casing F.
When the sliding valve is in the position as shewn in Figure 2 and the pressure
admitted to the pipe G, the steam, compressed air, or water will act upon the
face of the tooth immediately in front thereof, causing the wheel to move in the
direction of the arrow, and as the latter rotates the valve J will slide up the
incline of the tooth and close the valve opening at J' thereby stopping the supply.
The rotation of the wheel allows the exhaust steam to pass up opening X, and if of
high initial pressure, by means of a second valve J we can admit the exhaust
steam to the faces of teeth T, the steam passing through the openings J', which
are opened and closed by means of the valve sliding up the incline of teeth in
rotating wheel, the steam or other fluid finally escaping through opening M.

page_text: When the sliding valve J has mounted to the top of the tooth, the spiral spring
will cause the valve to drop down to the bottom of the next tooth, thus re-opening
J and admitting pressure to act on the next tooth and so on continuously so
long as the pressure is in the pipe G.
The small valve J2 shewn only at the back of the valve-casing F is acted upon
in the same manner as the sliding valve J by which any back pressure is allowed
to escape to the atmosphere, and the pipe X on the opposite side of J is so placed
that as soon as the pressure from sliding valve J acts upon another tooth, the
steam, compressed air, or water is allowed to escape from the space or tooth last
acted upon, and can be again used expansively on two or more teeth as before
described.
In Figure 2 we have only shewn two sets of valves fitted to the wheel, but we
wish it to be understood that more valves of the same construction may be placed
around the circumference of the wheel, the number varying according to the power
required, and to the initial pressure at command in order to obtain the advantages
of high pressure steam as in a compound engine.
What we claim as our invention is :-
The combination of a wheel having angular teeth with one or more automatic
opening and closing sliding valves arranged in the manner and for the purpose as
hereinbefore described
In Witness whereof, I the said Squire Broadbent, for and on behalf of myself
and the said Squire Broadbent the younger, have hereunto set my hand and
seal this thirtieth day of May in the year of our Lord One thousand eight
hundred and eighty three.
