page_text: LETTERS PATENT to Herbert John Haddan, of the Firm of Herbert and
Company, Patent Agents, of 67, Strand, in the City of Westminster, Civil
Engineer, for the Invention of "IMPROVEMENTS IN COAL AND ASH SIEVES." A
communication from abroad by Peter Peckham, of New York City, United
States of America
Sealed the 6th April 1877, and dated the 23rd October 1876.
PROVISIONAL SPECIFICATION left by the said Herbert John Haddan at the
Office of the Commissioners of Patents on the 23rd October 1876.

The improvements consist in the use of a perforated disk fitted inside a cylindrical
vessel and attaching a handle or handles to said disk, by means of which the same
may be rotated inside the said cylinder, and the coal ashes and such like placed on
the disk be by the rotation of the same freed from dust, cinder, and such like; the
various parts may be of metal and made plain or ornamental.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by the
said Herbert John Haddan in the Great Seal Patent Office on the 18th April
1877.

page_text: The Invention consists in placing a perforated disk, serving as the coal sifter,
inside of a cylindrical vessel, and attaching a handle or handles to the said coal
sifter, by aid of which the same is rotated inside of the said cylinder. The coal
being placed on the top of the sifter will be freed from ashes, dust, and cinders,
simply by rotating the sifter by aid of the handle or handles. The perforated disk
forming the coal sifter may be supported inside of the cylinder in different ways
without changing the result of the operation.
In order more fully to describe the Invention I refer to the accompanying
Drawing forming a part of this Specification.
Figure I. represents a vertical sectional view of my improved coal and ash sifter;
Fig. 2 is a top view of the same.
Fig. 3 is a vertical sectional view, showing how the perforated disk B is supported
by rivets or friction rollers R, placed inside of the cylindrical vessel A, the handle
D being guided by the cross bar S. Fig. 4 is a top view of the same.
Fig. 5 is a vertical section showing that the perforated disk B is held in the
cylinder A where desired, by aid of the hand; the handle D serving as a guide for
the perforated disk. Fig. 6 is a top view of the same.
Fig. 7 is a vertical sectional view, showing how the perforated disk B is held inside
the cylinder A by aid of the shoulders E, E, on the handle D which rest on the
hinged cover F, which also serves as a guide, and revolves with the handle and the
perforated disk. Fig. 8 is a top view of the same.
Fig. 9 is a vertical sectional view showing how the perforated disk is supported
in the cylinder A by aid of the rim G, which is formed in the inetal. The cover O
is provided with a slot a and lid b, allowing the handle D to pass through the
cover; the lid, when closed, prevents. the exit of dust. Fig. 10 is a top view of the
same.
Fig. 11 represents a top view of a cylinder H, the side view being shown in
Fig. 9, placed on the top of the perforated disk B, fastened or not, holding the coal
on the sifter when the same is withdrawn from the cylindrical vessel.
Fig. 12 represents a front view of a handle I fastened to the outside of the
cylinder A, by aid of which the apparatus is held to a wall, when required, by aid
of a hook or nail. Fig. 13 is a side view of the same.
Fig. 14 is a vertical sectional view, showing that vertical rods J, J, are fastened
to the cover D¹ for the purpose of stirring the coal, pushed against the same when
being sifted. The cover D¹ is provided with a cross bar K for giving strength and
holding it firmly to the cylindrical vessel A by coupling m. Fig. 15 is a top view
of the same..
The
Fig. 16 is a vertical sectional view showing the cylinder H provided with a cross
bar d with spindle or loose rivet e at the bottom, on which revolves the perforated
disk B, to which the two vertical rods f, f, are fastened. The cylinder H is
provided with lips 8, s, which rest on the rim of the cylindrical vessel A.
cover g, with slots h, h, slips over the end of the rods f, f, and the perforated disk
B is thus revolved by taking hold of the end of the rods f, f, or a separate lever q
may be fastened to the cover g. Fig. 17 is a top view of the same with the cover g
removed, and Fig. 18 is a top view of the same with the cover g in its place.
Referring to Figs. 1 and 2, A is the cylindrical vessel in which the perforated
disk or coal sifter B is placed. To the perforated disk B is fastened the handle D,
which is provided with the perforated cross rod N. M is a spindle fastened to the
bottom of the vessel A in the centre, and this spindle or rod serves as a guide for
the perforated disk, which is rotated and elevated by the hand as the ashes
accumulate at the bottom of the vessel A. W is a vessel serving as a coal scuttle,
and serves also as a cover for the vessel A.
If desired, the vessel A may be made in two separate parts, with joints, so that
the lower part containing the ashes may be removed separately from the apparatus.
Having thus described the Invention, I desire to claim, a coal and ash sifter,
consisting of the perforated disk B, with the handle D, in combination with the

page_text: cylindrical vessel A, substantially, as shown and described, and for the purpose
set forth.
In witness whereof, I, the said Herbert John Haddan, have hereunto set my
hand and seal, this Seventeenth day of April, in the year of our Lord One
thousand eight hundred and seventy-seven.
