PROVISIONAL SPECIFICATION.
Improvements in Steam and other Motive Power Engines.
WILLIAM TURNER LORD, Stamford Brook Villa, Hammersmith, London, W.,
do hereby declare the nature of this invention to be as follows :—
The object of my invention is to effect the economical use of steam, compressed
air, or other fluid, by such simple construction that high speed, and great regularity,
under varying loads, can be obtained.
I form an opening through cylinder cover, and a chamber or steam box upon the
cover ending in a cap or extra box with opening in any suitable part, conducting
to exhaust.
Steam is conducted from the boiler into the chamber or steam box; at each end
of this box are rings or some other form of packing.
Within this steam box is a sleeve piece with one or more openings through which
steam can pass, or the steam box can be formed so as to dispense with a sleeve
piece. Where it is required to have variable, or automatic cut off; this sleeve or
slipper, is made to rotate by means of the governor, and the opening or openings
are formed within the compass of a right angled triangle one of the right sides
being parallel with plane of cylinder cover, and the other at right angles to it and
parallel with axis of sleeve.
The piston is formed with a long hollow cylinder attached to it in any convenient
manner. This cylinder is partitioned into two parts to form passages for conducting
live steam into the cylinder, and exhaust steam from the cylinder. At the base of
this cylinder is a valve either oscillating slide or other form, which can be moved
by the throw of the crank and connecting rod or any other suitable means, by which
when the piston is at the top of the stroke, the valve will open a port or passage
which will allow steam to pass from steam box down steam passage in long cylinder
into the cylinder proper and at the bottom of stroke this valve will close, and by
the same means another port or passage will open and allow steam to pass from
cylinder into exhaust passage of long cylinder and away.
The rotating of the sleeve, by the governor or by hand will bring a long or short
part of the opening or openings in it, opposite the opening of steam passage in long
cylinder and allow a proportionate quantity of steam to enter the cylinder, and by
having a throttle valve in connection with this an automatic cut off and governor
will be made.
I shape the top of piston with raised rim when it is desirable to keep the packing
rings above the level of top of oscillating or other valve and or to collect the con-
densed steam near mouth of exhaust and to obtain good fixing for the long cylinder
in head of piston.
My connecting rod and crank can be either exposed, or enclosed in a chamber.
In either or both cases I arrange for lubricating cranks by means of oil ducts and
grooved channels, which utilizes the centrifugal motion to convey the lubricant
also. I form the crank case, or fit to it if open suitable guards, to prevent the
oil &c. being thrown outside the engine.

Improvements in Steam and other Motive Power Engines.
WILLIAM TURNER LORD, Stamford Brook Villa, Hammersmith, London, W..
Architect, 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 :—
My invention specially applies to quick running engines, altho' applicable to
others.
To illustrate and describe it, I use the drawing in which Fig. 1. is a section of the
upper part of a single acting engine, of which 1 is the cylinder & 2 the piston.
which has an extension 12 which passes through the cylinder top 4 which has a
steam box 3. formed upon it, or, as shewn in Fig. 2 and 3, is carried up as a
sleeve 6, in which the extension 12 work-.
The sleeve 6 has one or more ports or opening, 31 open to the steam supply
which enters from 11.
There is an upper sleeve or box 7, connected with exhaust 8. Packing of any
suitable kind is used upon or about the extension 12 to confine the steam supply
within its limits, until it is used through the passage 27. (two arrangements are shewn
at 9 and 10). The extension 12 is divided by a central partition 26 into the
passage 27 and 28; one serving to conduct steam to the valve passage and ports 14
15 & 16, into the cylinder: and on the return stroke, when the valve has been
reversed; through 23. 24 & 25. through the passage 28, to exhaust 8: or in
compounded engines, for further expansion in low pressure cylinder.
The port 30. can be modified in size or shape, or several openings can be made.
and the same modification can be made in 31.
In Figs. 2 and 3. a modification of detail is shewn, in which the base of 12 is
widened out to allow the formation of the passage 16, which is alternately connected
with 14 and 25.
It will be evident that if the functions of 27 and 28 are reversed, or made
reversible at option the engine will be reversible.
Flaving now particularly described and ascertained the nature of my said inven-
tion, and in what manuer the same is to be performed, declare that what I
claim is :--
1st. The tubular extension ecnnerted with the piston and divided into two
passages to serve as supply and exhaust passages.
2nd. The combination of the tubular extension of piston with the trunk piston
containing an oscillating or other valve, the said extension of piston, being divided
into passages as herein set forth.
3rd. The general combination of parts as herein set forth.
