Year: 1875

page_text: LETTERS PATENT to William Dewhirst Cliff, of Wortley, near
Leeds, in the County of York, for the Invention of "IMPROVE-
MENTS IN CARRIAGES FOR RECEIVING CLAY RETORTS AND OTHER SIMILAR
HEAVY ARTICLES AS THEY ARE MADE, AND FOR CARRYING THEM AWAY AND
DEPOSITING THEM WHERE REQUIRED.
"
Sealed the 18th February 1876, and dated the 2nd December 1875.
PROVISIONAL SPECIFICATION left by the said William Dewhirst
Cliff at the Office of the Commissioners of Patents, with his
Petition, on the 2nd December 1875.
I, WILLIAM DEWHIRST CLIFF, of Wortley, near Leeds, in the
County of York, do hereby declare the nature of the said Invention
for "IMPROVEMENTS IN CARRIAGES FOR RECEIVING CLAY RETORTS AND OTHER
SIMILAR HEAVY ARTICLES AS THEY ARE MADE, AND FOR CARRYING THEM AWAY
AND DEPOSITING THEM WHERE REQUIRED," to be as follows:-

page_text: raised and lowered at pleasure. This may be done in various ways,
for instance, by arrangements of worms and worm wheels, racks and
pinions, screws, wheels, and levers; by hydraulic pressure, or by the
pressure of steam or compressed air in combination with cylinders and
pistons, or by eccentrics, cams, or cranks mounted or formed on shafts
carried by the framing of the carriage or on the axles of the carrying
wheels, in which latter case the wheels would be arranged to run loosely
on their axles.
The present Invention is specially adapted for use in combination
with my "Improvements in Machinery for Making Clay Retorts and
other similar Heavy Articles made from Clay," forming the subject of
former Letters Patent granted to me, dated June 11, 1874, No. 2034.
The mode in which carriages constructed according to my present In-
vention are used is as follows:-The carriage is placed in position on
the table H, described in the Specification of Letters Patent herein-
before referred to, either with the moveable top thereof in a raised,
lowered, or intermediate position. On the moveable top of the carriage
is placed a loose board or receiver, which overhangs or projects beyond
the sides of the carriage. The table H is then moved up to the die
used in the formation of the retort or other similar heavy article.
When the retort or other article is made, the carriage is run off to the
place where it is desired to place it. Loose blocks or packings or other
supports are then inserted underneath two or three of the overhanging
sides of the loose board or receiver, or the carriage may be run into
position between suitable supports. The moveable top of the carriage
is then lowered, when the packings or supports take the weight of the
retort or other article, after which the top is still further lowered, when
the carriage is drawn out leaving the retort in the desired position.
1.
If the moveable top of the carriage is in its normal or lowest position
when the retort is made, then when taken to its place in the shed, the
moveable top of the carriage must be first raised in order to enable the
loose board to be placed in position on the moveable blocks or packings
or other supports, after which the moveable top is lowered, leaving the
retort or other article in its desired position.

filed by the said William Dewhirst Cliff in the Great Seal
Patent Office on the 31st May 1876.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
DEWHIRST CLIFF, of Wortley, near Leeds, in the County of York,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Second day of December, in the
year of our Lord One thousand eight hundred and seventy-five, in the
thirty-ninth year of Her reign, did, for Herself, Her heirs and suc-
cessors, give and grant unto me, the said William Dewhirst Cliff,
Her special license that I, the said William Dewhirst Cliff, my
executors, administrators, and assigns, or such others as I, the said
William Dewhirst Cliff, my executors, administrators, and assigns,
should at any time agree 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 CARRIAGES FOR RECEIVING
CLAY RETORTS AND OTHER SIMILAR HEAVY ARTICLES AS THEY ARE MADE,
AND FOR CARRYING THEM AWAY, AND DEPOSITING THEM WHERE REQUIRED,'
upon the condition (amongst others) that I, the said William
Dewhirst Cliff, my executors or administrators, by an instrument in
writing under my, or their, or one of their hands and seals, 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 I, the said William Dewhirst Cliff, do
hereby declare the nature of the said Invention, and in what manner
the same is to be performed, to be particularly described and ascer-
tained in and by the following statement thereof, that is to say :—
The Invention consists in so constructing the carriage that the top
thereof, which is properly supported and guided, is capable of being
raised and lowered at pleasure. This may be done in various ways,

page_text: for instance, by arrangement of worms and worm wheels, racks and
pinions, screws, wheels, and levers; by hydraulic pressure, or by the
pressure of steam or compressed air in combination with cylinders and
pistons, or by eccentrics, cams, or cranks mounted or formed on shafts
carried by the framing of the carriage, or on the axles of the carrying
wheels, in which latter case the wheels would be arranged to run loosely

page_text: readily raised or lowered through the action of the toggle links or
levers d, d¹.
The mode in which carriages constructed according to my present In-
vention are used is as follows:-The carriage is placed in position on or
run on to the table H, described in the Specification of Letters Patent
herein-before referred to, either with the moveable top c thereof in a
raised, lowered, or intermediate position. On the moveable top c of the
carriage is placed a loose board or receiver, which overhangs or projects
beyond the sides or frame a of the carriage. The aforesaid table H is
then moved up to the die used in the formation of the retort or other
similar heavy,artiole.
When the retort or other article is made the carriage is run off to
the place where it is desired to place it. Loose blocks or packings or
other supports are then inserted underneath two or three of the over-
hanging sides of the loose board or receiver, or the carriage may be run
into position between suitable supports. The moveable top c of the
carriage is then lowered, when the packings or supports take the weight
of the retort or other article, after which the top c is still further
lowered, when the carriage is drawn out, leaving the retort in the
desired position.
If the moveable top c of the carriage is in its normal or lowest
position when the retort is made, then when taken to its place in the
shed, the moveable top c of the carriage must be first raised, in order to
enable the loose board to be placed in position on the moveable blocks
or packings or other supports, after which the moveable top c is
lowered, leaving the retort or other article in its desired position.
Having thus described the nature of my said Invention and the mode
in which I prefer to carry the same into effect, I would here remark
that I do not confine myself to the means herein shown and described
for raising and lowering the top c of the table, nor to the forms of the
guides for such top, as many arrangements would readily be suggested
to the mind of a competent mechanic for effecting the same purpose;
but what I do claim as my said improvements in carriages for receiving
clay retorts and other similar heavy articles as they are made, and
for carrying them away, and depositing them where required, is the
adaptation to or combination with the carriage body or frame a of a
moveable top c, arranged to work in suitable guides and capable of

page_text: being readily raised and lowered in manner and for the purpose sub-
stantially as herein shown and described.
In witness whereof, I, the said William Dewhirst Cliff, have
hereunto set my hand and seal, this Twenty-fourth day of May,
in the year of our Lord One thousand eight hundred and seventy-
six.
