Sealed the 29th December 1874, and dated the 10th October 1874.
COMPLETE SPECIFICATION filed by the said George Haseltine at the
Office of the Commissioners of Patents, with his Petition and
Declaration, on the 10th October 1874, pursuant to the 9th Section
of the Patent Law Amendment, Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
HASELTINE, of the "International Patent Office," Southampton Build-
ings, London, Doctor of Laws, send greeting.
WHEREAS I am in possession of an Invention for "IMPROVEMENTS
IN APPARATUS FOR FEEDING GAS RETORTS, AND FOR OTHER ANALOGOUS PURPOSES,”
and have petitioned Her Majesty to grant unto me, my executors,
administrators, and assigns, Her Royal Letters Patent for the same, and
have made solemn Declaration that it has been communicated to me

page_text: from abroad by James Bothwell, of Emerald Hill, near Melbourne,
Victoria, Stoker.
NOW KNOW YE, that I, the said George Haseltine, do hereby declare
that the following Complete Specification, under my hand and seal,
fully describes and ascertains the nature of the said Invention, and in
what manner the same is to be performed, in and by the following
statement, reference being had to the accompanying Drawing forming
part of this Specification :-
This Invention consists of certain improvements in apparatus for
feeding gas retorts and for other analogous purposes, which have been
designed for the purpose of enabling the scoops to be worked with
greater facility and with less loss of gas during the operation of feoding.
Hitherto they have been carried from the coal heap to the retort by three
men, one at the end or handle, and one at either end of a horse placed
underneath the body of the scoop. Now by my method only one man is 1
required for the work. I provide a travelling under carriage, upon
which I construct a bed for the scoop to rest in, at the same level as the
retorts to be fed. A scoop so constructed and arranged can be wheeled
to the coal heap and filled; the retort can then be opened and emptied
of its coke, and the scoop wheeled round so as to enable it to be run
right into the retort, turned over, emptied, and finally drawn back again
on its bed, wheeled away, and if necessary refilled whilst the door of the
retort is being closed up. In order to make the same under carriage
answer for retorts on different levels I make the height of the beds
adjustable. The method shewn in the Drawings consists of a fixed stud
or spindle on the under carriage, over which there passes a tubular
support for the bed. These tubular supports are made of different
lengths, so as to carry the scoops on a level with the several layers of
retorts. Other means of making them adjustable may be substituted for
those I have described

tho scoop when it is being withdrawn from the retort.
·
Having thus described the nature of my Invention, and the manner
of performing the same, I would have it understood that I do not
confine myself to any particular shape or size of scoop, or to the height
of the bed on which it rests, or to the method of adjusting it, or to the
nature of the travelling under carriage, nor to any other precise detail,
but Talaim
Second. The use of semicircular peas on traveling under carriages for
such scoops.
Third. The use of adjustable supports for such beds.
In witness whereof, I, the said George Haseltine, have hereunto set
my hand and scal, this Tenth day of October, in the year of our
Lord One thousand eight hundred and seventy-four.
