TPROVEMENTS IN GARDEN ENGINES
Year: 1875

page_text: LETTERS PATENT to John Sanders Stevens, of No. 69, Princes Street,
Leicester Square, in the County of Middlesex, for the Invention
of "TPROVEMENTS IN GARDEN ENGINES”
PROVISIONAL SPECIFICATION left by the said John Sanders Stevens
at the Office of the Commissioners of Patents, with his Petition,
on the 10th April 1875.
I, JOHN SANDERS STEVENS, of No 69, Princes Street, Leicester
3 Square, in the County of Middlesex, do hereby declare the nature of
the said Invention for "IMPROVEMENTS IN GARDEN ENGINES," to be as
follows:-
This Invention consists in constructing garden engines in such manner
that the pump may be driven from the running wheel or wheels on
which the engine is mounted, so that at the same time that the engine
is moved either forwards or backwards the pump may be brought into
action and a stream of water delivered from the delivery jet or spreader.

page_text: This I prefer to effect by mounting a shaft above the top of the barrel
which contains the water supply of the engine, and driving such shaft by
means of an endless chain gearing with a chain wheel, which can be
made fast with the running wheels of the engine. This chain wheel I
make of larger diameter than the pinion upon the shaft, so that the
shaft shall revolve at a greater speed than the running wheels. From a
crank upon the shaft I transmit an up-and-down motion to the pump
rod. Other means than those above described may however be adopted
for transmitting motion from the running wheel or wheels of the engine
to the pump rod.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Sanders Stevens in the Great Scal Patcut
Office on the 8th October 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
SANDERS STEVENS, of No. 69, Princes Street, Leicester Square, in the
County of Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Tenth day of April, in the year of our
Lord One thousand eight hundred and seventy-five, in the thirty-
eighth year of Her reign, did, for Herself, or heirs and successors,
give and grant unto me, the said John Sanders Stevens, Her special
license that I, the said John Sanders Stevens, my executors, admi-
mistrators, and assigns, or such others, as I, the said John Sanders
Stevens, my executors, administrators, and assigns, should at any
time agreo with, and no others, from time to time and at all times
thereafter 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 "IMPROVEMENTS IN GARDEN ENGINES," upon the condition (amongst
others) that I, the said John Sanders Stevens, my executors or admin-
istrators, by an instrument in writing under my, or their, or one of
their hands and scals, 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

page_text: Office within six calendar months next and immediately after the date
of the said Letters Patent.
NOW KNOW YE, that I, the said John Sanders Stevens, 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:―
This Invention consists in constructing garden engines in such manner
that the pump may be driven from the running wheel or wheels on
which the engine is mounted, so that at the same time that the engine
is moved cither forwards or backwards the pump may be brought into
action and a stream of water delivered from the delivery jet or spreader.
This I prefer to effect by mounting a shaft above the top of the barrel
which contains the water supply of the engine, and driving such shaft by
means of an endless chain gearing with a chain wheel, which can bo
made fast with the running wheels of the engine. This chain wheel I
make of larger diameter than the pinion upon the shaft, so that the
shaft shall revolve at a greater speed than the running wheels. From a
crank upon the shaft I transmit an up-and-down motion to the pump
rod. Other means than those above described may however be adopted
for transmitting motion from the running wheel or wheels of the engine
to the pump rod.

page_text: Having thus described the nature of my said Invention and the
manner of performing the same, I would have it understood that what I
claim is, the construction of garden engines in which the pump is driven
from the bearing wheels.
In witness whereof, I, the said John Sanders Stevens, have herc-
unto set my hand and scal, this Seventh day of October,
in the year of our Lord One thousand eight hundred and seventy-
five.
