and pumps, the improvements being based upon a previous Patent granted to me,"
dated 1st July 1876, No. 2716
In the Specification of that Patent I described sectors or quadrants working
within a rectangular frame as a piston, by which a direct thrust is obtained upon
the crank pin of the main shaft during the whole of its travel.
Now my present Invention consists in fitting sectors or quadrants in a frame; of
skeleton or other form, as an attachment to a piston rod or rods, so that the crank
pin may partake of a direct thrust from the rod or rods during the whole of its
travel apart from the positive action of the pistons, as previously referred to. The
quadrants or sectors are hung, suspended, or otherwise supported on vibrating links
or rods from plates or straps affixed to the piston rod or rods, to regularize the
motion during their oscillatory movements.
In arranging my quadrants or sectors on a frame, separate from the piston, I
purpose fitting them between two cylinders, in each of which is a piston for the
steam or other agent to act upon in alternate order for the to-and-fro travels, the
valves being arranged for the admission and for the exhaust from a rod worked by
an eccentric on the main shaft. The steam pipe is branched to serve both cylinders

jacket at the lower part into which the exhaust steam passes, the latter jacket being
in direct connection with a hollow base as a condenser. By this means the
cylinders or casings are kept hot,' and the admission valves also serve for the
exhaust.
Each single cylinder or casing may have the steam and exhaust passages formed
in the same casting.
In fitting my sector or quadrant mechanism within a piston, as described in the
Specification of my previous Patent, I form the steam pipe on the casing in the
same casting instead of having a separate pipe.
In applying my sector or quadrant mechanism to work the crank of ordinary
engines, I fit it outside and connect it to the piston rod or rods. I can also work
valve rods of engines by my mechanism.
The before-mentioned appliances are applicable to fast running engines, and also
for pumps.
In using two cylinders or power casings, one may be used as a pump barrel if
desired

"IMPROVEMENTS CONNECTED WITH STEAM AND OTHER ENGINES AND PUMPS."
:
This Invention relates to improvements connected with steam and other engines
and pumps, the improvements being based upon a previous Patent granted to me,
dated 1st July 1876, No. 2716.
In the Specification of that Patent I describe sectors or quadrants working
within a rectangular frame as a piston, by which a direct thrust is obtained upon
the crank pin of the main shaft during the whole of its travel. '
Now my present Invention consists in fitting sectors or quadrants outside the
steam cylinder or cylinders in a frame of skeleton or other form as an attachment
to à piston rod or rods, so that the crank pin may partake of a direct thrust from
the rod or rods during the whole of its travel apart from the positive action of the
pistons, as previously referred to. The quadrants or sectors are hung, suspended, or
otherwise supported on vibrating links or rods from plates or straps affixed to the
piston rod or rods, to regularize the motion during their oscillatory movements.
In arranging my quadrants or sectors on a frame, separate from the piston, I
purpose fitting them between two cylinders, in each of which is a piston for the steam
or other agent to act upon in alternate order for the to and fro travels, the valves
being arranged to act for the admission and for the exhaust from a rod worked by
an excentric on the main shaft, the steam pipe is branched to serve both cylinders
or casings from above, where a steam jacket is formed at the upper part and

page_text: another jacket at the lower part into which the exhaust steam passes, the latter
jacket being in direct connection with a hollow base as a condenser. By this means
the cylinders or casings are kept hot, and the admission valves also serve for the
exhaust.
Each single cylinder or casing may have the steam and exhaust passages formed
in the same casting.
By this
When I use one cylinder only I sometimes fit a pump barrel to the opposite end
of the foundation plate, so that the rod or rods of the rectangular or square frame
is or are attached to the plunger or bucket by which the liquid is raised.
means I make a direct-acting steam pump of a very simple character; such also is
the case with the two cylinder engine; the pump may however be disconnected,
whereby a single cylinder engine is formed for driving purposes generally.
An example of my Invention is shown in the annexed Drawings, Figure 1 of
which is a view of a two cylinder engine A, A, whose pistons B act upon the
rectangular frame by its attachment to the piston rods C, C, which preserve the
parallel action of the frame.
The upright or end bars D, D, are held at a fixed distance apart by collars and
keys on the stay or tie bars E, E; F, F, are links pinned loosely to the end
bars D, D, and with their upper ends G, G, linked to the top segments of the
quadrants H, H, so that the faces of the quadrants are kept constantly in contact
with the inner faces of the end pieces D, D, to ensure a direct thrust being taken
by the quadrants, and consequently the crank as the pistons push and draw the
frame along which direct action is maintained upon the crank during every part of
its circular travel in either direction.
I, I, are branches to supply steam to the two cylinders A, A, the branches leading
from one pipe J.
K, K, are valves taking a steam supply from the top chambers L, L, of the
cylinders, the valves acting alternately to admit steam to the faces of the pistons
B, B, when the rods M, M, are acted upon by the excentric N from the main
shaft P.
•
Qis a block carrying the shaft, the block being in halves which can be slid open
upon two supporting rods R, R, to admit the shaft and to allow for adjustment from
wear. The ends of the block are rigidly fixed to lugs upon the cylinders or to
uprights alongside the cylinders, as found convenient.
S is the fly wheel.
The valves K, K, are also exhaust valves to lead the spent steam into the opposite
end chambers T, T, of the cylinders, from whence it is condensed in the base
plate U, or may be blown off, as desired.
The rectangular frame may also be applied to an ordinary steam engine, for acting
upon the crank in the manner explained instead of the usual cross head sliding
block and connecting rod, if desired.
It will be seen that in Figure 1 the quadrants are supported by the links F, F.
In Figure 2 the quadrants are held and maintained in position by two thin bands
a, a, of springy steel placed between the working faces of the quadrants and the
end bars D, D, as shown, the upper ends of which are fastened to the inner faces of
the end bars D, D, by small screws b, b, whilst the lower ends are fastened in a
similar manner by screws c, c, to the lower ends of the quadrants H.
It is obvious that the two cylinders A, A, Figure 1, may be replaced by pump
barrels, and the piston or plunger reciprocated by the crank shaft P receiving
rotary motion from any prime mover.
And having now described the nature of my said Invention, and in what manner
the same is to be performed, I declare that I claim,-
First. Fitting a rectangular or square frame to piston rods of engines outside of
and between two cylinders, or of one cylinder only, said frame having two quadrant-
shaped levers within and against it, and against a crank of the engine shaft, as and
for the purposes described, and substantially as shown in the annexed Drawings.

page_text: Secondly. I claim the combination of appliances forming a two-cylinder engine,
as described, and as shown in the annexed Drawing for the purposes set forth.
Thirdly. I claim the method of supporting the quadrants H, H, by the bands of
steel, as herein-before described, and substantially as shown in the annexed
Drawings for the purposes set forth.
In witness whereof, I, the said Joseph Edlyn Outridge, have hereunto set
my hand and seal, this Twenty-ninth day of April, One thousand eight
hundred and seventy-eight.
