IMPROVE- MENTS IN MACHINERY FOR TRANSMITTING POWER."
Year: 1864

page_text: LETTERS PATENT to Thomas Smith and Thomas Lister, of Hippenholme,
near Halifax, in the County of York, for the Invention of "IMPROVE-
MENTS IN MACHINERY FOR TRANSMITTING POWER."
PROVISIONAL SPECIFICATION left by the said Thomas Smith and
Thomas Lister at the Office of the Commissioners of Patents, with their
Petition, on the 12th February 1864.
We, THOMAS SMITH and THOMAS LISTER, of Hippenholme, near Halifax,
in the County of York, do hereby declare the nature of the Invention for
"IMPROVEMENTS IN MACHINERY FOR TRANSMITTING POWER," to be as follows:-
This Invention has for its object improvements in machinery for trans-
mitting power. For these purposes the power of a steam engine or other
first. mover is applied to drive a shaft, on which are fixed two excentrics, each
of which in its rotation gives motion to and lifts one end of a weighted lever
which moves on a fulcrum at its other end. Each of these levers at a point
near to the fulcrum by a connecting rod gives motion to a piston in a cylinder.
To each of the cylinders there is a branch pipe of less diameter than the

page_text: cylinder, and it is preferred that each cylinder should gradually diminish in
diameter till it comes to the diameter of the branch pipe. Water or other
fluid is placed in each cylinder, and its branch pipe and the proper quantity of
fluid is kept supplied to each by a suitable inlet, and there is a safety valve
applied on each branch pipe to regulate the pressure. Within the outer end
of each of the branch pipes is a piston or plunger of less diameter than the
piston in the cylinder connected with such branch pipe, hence as the pistons
in the cylinders are caused alternately to move a distance in their respective
cylinders by the descent of their weighted levers, the pistons or plungers in
the respective branch pipes will be moved a distance and at an increased
speed to the pistons in the cylinders, depending on the relative areas of the
plungers in the branch pipes and the areas of the pistons in the cylinders.
The rods of the plungers or pistons which work in the outer ends of the
branch pipes are by suitable rods connected to cranks on a crank shaft, on
which there is a fly wheel, and from such crank shaft the power is com-
municated to the machinery which it is desired to drive. The speed of
rotation of the crank shaft, as compared with the first shaft on which..the.
excentrics are fixed, will depend on the relative areas of the pistons in the
cylinders and the areas of the plungers or pistons in the branch pipes.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Thomas Smith and Thomas Lister in the Great Seal Patent
Office on the 12th August 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, THOMAS
SMITH and THOMAS LISTER, of Hipperholme, near Halifax, in the County
of York, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twelfth day of February, in the year of our Lord
Que thousand eight hundred and sixty-four, in the twenty-seventh year
of Her reign, did, for Herself, Her heirs and successors, give and grant unto
us,. the said Thomas Smith and Thomas Lister, Her special licence that we,
the said Thomas Smith and Thomas Lister, our executors, administrators,
and assigns, or such others as we, the said. Thomas Smith and Thomas
Lister, our executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times thereafter

page_text: during the term therein expressed, should and lawfully might make, use,
exercise, and vend, within the United Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, an Invention for "IMPROVE-
MENTS IN MACHINERY FOR TRANSMITTING POWER," upon the condition (amongst
others) that we, the said Thomas Smith and Thomas Lister, our executors or
administrators, by an instrument in writing under our or their hands and seals,
or under the hand and seal of one of us or them, should particularly describe
and ascertain the nature of the said Invention, and in what manner the
same was to be performed, and cause the same to be filed in the Great Seal
Patent Office within six calendar months next and immediately after the date
of the said Letters Patent.
NOW KNOW YE, that we, the said Thomas Smith and Thomas Lister, do
hereby declare the nature of the said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained in and
by the following statement thereof (that is to say) :-
one end of a weighted lever,
Each of these levers at a point
This Invention has for its object improvements in machinery for trans-
mitting power. For these purposes the power of a steam engine or other first
mover is applied to drive a shaft on which are fixed two excentrics, each of
which in its rotation gives motion to and lifts
which moves on a fulcrum at its other end.
near to its fulcrum by a connecting rod gives motion to a piston in a cylinder..
To each of the cylinders, there is a branch pipe of less diameter than the
cylinder, and it is preferred that each cylinder should gradually diminish in
diameter till it comes to the diameter of the branch pipe. Water or other
fluid is placed in each cylinder and its branch pipe, and the proper quantity of
fluid is kept supplied to each by a suitable inlet, and there is a safety valve
applied on each branch pipe to regulate the pressure. Within the outer end
of each of the branch pipes is a piston or plunger of less diameter than the
piston in the cylinder connected with such branch pipe, hence as the pistons
in the cylinders are caused alternately to move a distance in their respective
cylinders by the descent of their weighted levers, the pistons or plungers in
the respective branch pipes will be moved a distance and at an increased
speed to the pistons in the cylinders, depending on the relative areas of the
plungers in the branch pipes and the areas of the pistons in the cylinders.
The rods of the plungers or pistons which work in the outer ends of the branch
pipes are by suitable rods connected to cranks on a crank shaft, on which
there is a fly wheel, and from such crank shaft the power is communicated to
the machinery which it is desired to drive. The speed of rotation of the crank

page_text: section, of apparatus arranged according to our Invention. a, a, is the framing
of the machine, at one end of which aro the standards a', a', which carry the
shaft or axis b, on which are fixed two excentrics 6. Motion is communicated
to the shaft from a steam engine or other motive power to drive the two
excentrics, which in their rotation give motion to and lift the weighted levers €,
which move on fulcrums at c³, carried by standards a³, a³, from the framing of
the machine. To each of the levers c is attached a connecting rod d, the other
end of which is connected to the piston or plunger e, which moves in the
cylinder f. To each of the cylinders f there is a branch pipe 9, of less
diameter than the cylinder, and, as will be seen by the Drawings, the cylinder f
gradually diminishes in diameter to that of the branch pipe. Within each
branch pipe is a piston or plunger h, and between this piston and that in the
cylinder water is supplied by the small pipe i, and a safety valvej is applied as
shewn to regulate the pressure in the cylinder and branch pipe. To each of
the pistons or plungers h is attached a rod k, which at its other end is attached
to the cross head l, which moves in guides formed in the framing of the
machine; thus it will be seen that as the pistons e are caused to move alter-
nately a distance in their respective cylinders by the descent of their weighted
levers c, the pistons or plungers in the branch pipes will be moved a greater
distance, and at an increased speed, depending on the relative areas of the
pistons or plungers e and h. To each of the cross heads is attached the con-
necting rod m, which gives motion to the crank shaft or axis n, which gives
motion to the machinery it is desired to drive. On the crank shaft or axis is
applied the fly wheel o, as shewn.
Figure 3 shows another arrangement, in which the connecting rod d is
attached to the end of the weighted lever c, and the fulcrum is arranged
intermediate of its length.
Although we have shown and described only two excentrics and apparatus
connected therewith for carrying our Invention into effect, three or more

page_text: excentrics and apparatus connected therewith may be advantageously
employed.
In witness whereof, we, the said Thomas Smith and Thomas Lister,
have hereunto set our hands and seals, this Sixth day of August, in
the year of our Lord One thousand eight hundred and sixty-four.
Signed, sealed, and delivered by the
above-named Thomas Smith and
