PROVISIONAL SPECIFICATION.
Improvements in and connected with Hydraulic and Pneumatic
Motors.
I, WALTER SMEDLEY of Ashover in the County of Derby, Tailor, do
hereby declare the nature of this invention to be as follows:-
:-
The object of my invention is to provide an improved construction or arrange-
ment of hydraulic or pneumatic motor or mechanism for obtaining the most
economic results therefrom.
In carrying out my invention I provide two or more cylinders, and for the sake
of illustration I will assume that there are two of the said cylinders, placed side
by side cach of which is bored in a vertical direction so that the bottom of the
vertical communicates with the end of the horizontal cylinder. Into the horizontal
parts of the cylinders insert suitable rams or pistons which are connected at
their outer ends to suitable cranks and shafting for the purpose of transmitting
the power given by the aforesaid rams or pistons. Into the two vertical parts of
the cylinders I place a sufficient quantity of water or any other liquid or gas that
may be equally suitable for my purpose, but which for the present purpose of
description I will assume to be water. Into each of these vertical cylinders 1
insert a vertical ram or piston carrying at its lower end the usual cup or the like
to come into contact with the water or other liquid or gas and the sides of the
cylinder. To one of the vertical rams and at a suitable distance from the top
thereof pivot or joint a lever and to the other ram nearest to the crank shaft I
connect the said lever by means of a swinging joint. The top or other suitable
portion of each ram is weighted in any adjustable or interchangeable manner.
Connected to one or both ends of the lever I arrange a suitable crank or cranks
which I drive by means of a motor the latter being preferably but not necessarily
driven by means of a compressed substance such as air, gas or liquid from an
accumulator provided with a suitable overflow or safety valve, the exhaust from
the accumulator I purpose to replace by means of a pump connected to the exhaust
reservoir.
The alternate rise and fall of the weighted rams communicates motion by means
of water or other liquid or gas to the horizontal rains an 1 cranked shaft, as the said
vertical rams are operated by means of the lever and motor.
It is evident that any suitable packing may be employed for the different joints
or bearings and that any suitable joints or connections be made between the
different parts also that any number of vertical or horizontal or approximately
vertical and horizontal rams and cylinders may be employed, and that any suitable
means may be employed for preserving a constant supply of water or other liquid
or gas to the various cylinders and receptacles without departing from the spirit of
my invention.

WALTER SMEDLEY Tailor Ashover Chesterfield. 1, de 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:-
Into
Into
The object of my invention is to provide an improved construction or arrange-
ment of hydraulic or pneumatic motor or mechanism for obtaining the most
economic results therefrom, &, in fully describing my arrangement, I purpose
giving details of the hydraulic arrangement for illustration. In carrying out my
invention, provide two or more cylinders, but, for the sake of illustration, I will
assume that there are two of the said cylinders Fig. 1 placed side by side at a
suitable distance apart, each of which is bored in a vertical, and also horizontal
direction, (that is to say, they resemble in form the letter L) Fig. (A 1) so that the
bottom of the vertical communicates with the end of the horizontal cylinder.
the horizontal parts of the cylinders, insert suitable rams A or pistons which
are connected at their outer ends to suitable cranks B and shafting C for the
purpose of transmitting the power given by the aforesaid rams or piston A.
the two vertical parts of the cylinders I place a sufficient quantity of water
suitable for my purpose. Into each of these vertical cylinders I also insert a ram
or piston D carrying at its lower end the usual cup or the like to come into contact
with the water & the sides of the cylinder. To one of the vertical rains, & at a
suitable distance from the top E thereof, I pivot, or joint a lever I and, to the
other ram,
I connect the said lever H by means of a swinging joint (or slot) F.
The top, or other suitable portion of each ram is weighted G in any adjustable or
interchangeable manner. Connected to one end of the lever Harrange a
suitable crank or eccentric, which drive by means of a water-motor Fig. 2,
the latter being driven by means of water under pressure from an hydraulic
accumulator Fig. 3, which is provided with a suitable overflow J or safety valve.
The exhausted water from the accumulator Fig. 3 & motor Fig. 2 I purpose to
replace by means of force-pumps Fig. 4 which are connected to the exhaust
reservoir Fig. 5. In constructing the force-pumps Fig. 4, I arrange two cylinders
side by side at the bottom or other suitable portion of the reservoir Fig. 5 which
I provide for the exhausted water from the water-motor Fig. 2. These two
force-pumps are connected by means of pipeing K to the hydraulic accumulator
Fig. 3 before mentioned with all necessary valves L etc. The rams or pistons D D
used for these force-pumps slide through bearings Z and are fitted at a suitable
distance from the top E with adjustable or interchangeable weights or springs G,
& are coupled together by means of a lever H and slot F which is also worked by
the water-motor Fig. 2 by means of a crank or eccentric I fitted to the outer end
of the lever H. The water under pressure in the accumulator Fig. 3 upon being
allowed to pass through the water-motor Fig. 2 communicates motion to the
lever H which is connected to the rams D D belonging to the force-pumps Fig. 4,
and at once commences to pump the water into the accumulator Fig. 3 from the
exhaust reservoir Fig. 5, and, owing to the rams D, D or pistons being weighted G,
the rise and fall of the lever H receives alternately its fulcrum from the
accumulator Fig. 3, thus gaining power which in turn gives the alternate rise and
fall to the weighted rams D D in the vertical portion of the two cylinders before
mentioned which are in the form of an L-Fig. A 1-and connected to suitable
shafting C with cranks B to give rotary motion. It is evident that any suitable
packing may be employed for the different joints or bearings, and, that any
suitable joints or connections may be made between the different parts; also, that
any number of vertical or horizontal, or approximately vertical and horizontal

page_text: rams and cylinders may be employed, and, that any suitable means may be
employed for preserving a constant supply of water or any other to the various
cylinders and receptacles without departing from the spirit of my invention.
Having now particularly described & ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is as follows:-
(1st.) An hydraulic accumulator with suitable fittings Fig. 3.
(2.) A water-motor with suitable fittings Fig. 2.
(3.) An exhaust reservoir to contain the water exhausted by the water-motor
Fig. 5.
(4.) Two force-pumps Fig. 4, with suitable valves, packing, and connections for
connecting to the aforesaid hydraulic accumulator.
(5.) Two rams D D fitted with cups and packing to fit the force-pumps, being
also fitted with adjustable or interchangeable weights or springs G.
(6.) One lever H fitted with slot F to connect the two rams D D belonging to
the two force-pumps Fig. 4 carrying at the outer end a crank or eccentric I to
connect to the water-motor Fig. 2.
(7.) Two cylinders bored in the form of an L Fig. 1.
(8.) Two rams DD to fit the vertical portion of the cylinders Fig. 1 fitted
with suitable adjustable or interchangeable weights or springs G.
(9.) Two rams A A. to fit the horizontal parts of the cylinders Fig. 1 fitted at
the outer end with cranks B or eccentrics to connect to the shafting C.
(10.) One piece of shafting C with suitable cranks & bearings.
(11.) One lever H fitted with slot F to connect the two vertical rams D D
belonging to the cylinders Fig. 1 aforementioned in Claim Seven.
(12.) One crank or eccentric to connect the lever H mentioned in
Claim Eleven, to the water-motor Fig. 2.
(13.) Suitable bearings Z, for the rams D D.
(14.) One small pin (M) to form a working radius for the levers.
(15.) O, one fly wheel or driving pully.
(16.) N space for inserting suitable tap & governors for starting & stopping.
