1, HENRY HARRIS LAKE of the firm of Haseltine, Lake & Co. Patent Agents
Southampton Buildings in the County of Middlesex do hereby declare the nature
of this invention and in what manner the same is to be performed to be particu-
larly described and ascertained in and by the following statement :—
The leading object of this invention is to construct a motor composed of two
plates hinged together end to end, the free end of one of the plates being pivoted
to a support, in the flowing water, and the free end of the other plate left free
to vibrate between two stops, whereby the water flowing in the direction of the
piston's length causes the latter to automatically play back and forth laterally,
thus effecting simplicity and cheapness in the production of motors.
Other objects relating to the exhaust valves and certain changes in the piston
are set forth in the detailed descripton.
While I term the device a water-motor, for which it is more especially designed,
I do not limit it to the use of water, for steam, air, or other elements of power
may be used.
Neither do I desire to limit the pistons for use in motors, as they are equally
applicable to meters for measuring liquids and fluid flowing through pipes, and
the like.
In the drawing forming a part of this specification, Fig. 1 is a view with one
wall of the piston support or flume removed Figs. 2 and 4, same showing
changes.
In Fig. 2 parts are broken away, and in Fig. 4 parts are in section on line 2, 2,
in Fig. 6 Fig. 3 a section on line 1, 1 in Fig. 2; Fig. 5 an elevation of a
detail from Fig. 4 pointed out by like letters, and Fig. 6 is a plan of part f in
Fig. 4.
Referring to the lettered parts of the drawing, B shows a flume or chest
through which the water or other element flows in the direction from the upper
to the lower end.

page_text: The flumes in Figs. 2 and 4 are different in shape and are supported by legs
so as to be used in a vertical position but they may be located horizontally as
in Fig. 1, or Fig. 1 in turn may be set vertically if supplied with water from a
spout or hose.
The piston in Fig. 1 is composed of two bars or plates D D¹ hinged together.
The lower end of the lower plate is pivoted in the flume near the exhaust port
or open end of the flume. The upper end of the upper plate is left free to play
between the stops U. Water entering the flume in Fig. 1 at the left side of the
piston will force said piston over to the other side of the flume where it assumes
a position like the one it occupies at left side in Fig. 1. It will be observed
that the free end of the piston rests on the right hand stop U. As soon as the
piston moves to the right side the free end of the piston will be tilted over against
the left hand stop, thus taking the water from this side and letting it into the
other side. Thus the piston continues to operate automatically by the action of
the flowing stream, the lower part of the piston vibrating on its pivot and the
upper part vibrating on its hinge. In lieu of a closed flume only open at each
end, an open frame or any suitable support having a part to which the piston is
pivoted, and stops to limit the movement of the upper end of piston, may be sank
in a flowing stream, and the piston will operate.
Motion may be transmitted to other machinery by means of a crank shaft
forming the pivot of the piston, or by a piston rod at right angles to the
piston and attached to it at or near the joint or hinge. See a in Fig. 1.
To economize water and increase power it is desirable to employ a flume having
an exhaust valve and adjustable stopgates U. This valve in Fig. 1. consists of a
bar having wings CC attached at the ends, said bar being pivoted centrally on
the pivots of the piston plates. In Fig. 1, the water has exhausted from the
right sids of the piston because the water flowing in at the left side has tilted the
valve so as to open the right hand exhaust and close the left hand exhaust.
When the piston moves to the right the reverse action of the valve will take
place and thus automatically open and close the exhaust port. The stop gates U
are hinged at one end to the walls of the flume at the induction port. They are
adjusted by screws by being swung further in or out to fix the limit of the
swing of the piston at the free end, and to prevent the water from flowing back
of said end.
In Fig. 4 the piston is made the same, except the lower end is rigidly attached
to a laterally moving slide f, having bearings between the angled walls of the
flume B and the rollers e. The water acts upon this piston the same as upon
the pistou in Fig. 1, and the action is the same, except the lower end moves
from side to side with the reciprocating slide instead of vibrating on a pivot.
The exhaust ports in Fig. 4 are through the slide f, and are closed automati-
cally by the valves or doors S. At the right the valve S has opened, the move-
ment of the slide to the left having released the valve from the right hand roller e
which held it closed, the same as the left hand roller is holding the other valve
closed. In Fig. 4 the water has exhausted through the open valve, and is entering
at the left of the piston. When the piston and slide move to the right the open
valve will close, the other will open, and the free end of the piston will tilt over
against the other side of the induction port of the flume, shutting the water from
the left side of the piston, and letting it in at the right side. In this Fig. it is
shown that the walls of the flume at the induction port may form the stops to
the free end of the piston.
Power may be transmitted by attaching a piston-rod to the slide fas at Y
Fig. 3, or by employing a crank shaft F, Figs. 4 and 5. This shaft F has a
crank P, and a radial arm A loosely coupled to the slide, at the outer end of
the arm, said arm being entered in an open slot of the slide f. Thus when the
slide reciprocates, the arm A will vibrate and operate the crank-shaft F.
The same slide and exhaust valves f S are shown in Figs. 2 and 3, except the
valves are pivoted in the ports a little off their center, and are closed by coming

page_text: in contact with the angled walls of the flume instead of by rollers
in Fig. 4.
The piston D in Fig. 2 is jointedly or pivotally attached directly to the slide f
and it vibrates from side to side in the flowing stream the same as the free end
of the other piston, and reciprocates the slide the same as in Fig. 4.
A forked piston-rod Y is shown in Fig. 3 which may be attached to the
slide in either Fig. 2 and 4.
Having now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed as communicated to me by my
foreign correspondent I declare that what I claim is :-
1st. A motor comprising a suitable flume or support, a vibrating piston, a crank
shaft or specified equivalent, and suitable stops to limit the movement of the piston,
substantially as set forth.
2nd. The combination of a suitable flume having eduction and induction ports, a
jointed piston pivoted in the flume at the eduction end and left free at the other
end, and suitable stops to limit the play of said free end, substantially as set
forth.
3rd. The combination of a suitable flume having induction and eduction ports,
a jointed piston, suitable stops to limit the vibration of said piston and autoinatic
exhaust-valves at the eduction ports, substantially as set forth.
