in the County of Middlesex, Optician, for the Invention of "IMPROVEMENTS
IN APPARATUS FOR ROASTING."
}
Sealed the 5th March 1861, and dated the 8th September 1860.
PROVISIONAL SPECIFICATION left by the said Geminiano Zanni at the
Office of the Commissioners of Patents, with his Petition, on the 8th
September 1860.
I, GEMINIANO ZANNI, of Upper King Street, Holborn, in the County of
Middlesex, Optician, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN APPARATUS FOR ROASTING," to be as follows:-
This Invention of improvements in roasting apparatus is applicable to all
kinds of apparatus in which joints of meat, poultry, or game are exposed to the
action of the naked fire and require to be basted. The Invention has for its :
object to baste the meat continuously and with regularity, and to continue this
operation while the meat is exposed to the fire. To effect this object, the fat
or dripping from the meat is allowed to fall into the dripping pan, from whence.
it is conveyed along a suitable channel to a vessel or reservoir, in which is
mounted a pulley or band wheel. Around this wheel is passed a band, chain,
or strap, which carries small scoops or buckets, and passes round another band
wheel or pulley at the upper part of the apparatus. This upper band wheel is
actuated by means of clockwork, a smoke-jack, or in any other convenient.
manner, and by this means rotary motion is communicated to the endless.chain.

page_text: of scoops or buckets, which by dipping into the liquid fat or dripping in the
vessel below, will raise the liquid and pour it into a channel above, from whence
it will run into a perforated channel or dish placed above the meat. By keeping
the endless chain of scoops or buckets in action while the meat is roasting,
the meat or joint will be kept properly basted, a regular and constant supply of
dripping being maintained.
This Invention is applicable to all kinds of roasters, and when the self-
acting basting apparatus is applied to a spit roaster on which several joints
may be roasting at the same time, the dripping-pan may, if desired, be so con-
structed as to receive the dripping from every joint of meat in separate com-
partments, and convey it away to distinct and separate receptacles, each of
which will be provided with an elevating apparatus, so that each joint may be
basted with its own fat or dripping.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Geminiano Zanni in the Great Seal Patent Office on the
8th March 1861.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEMINIANO
ZANNI, of Upper King Street, Holborn, in the County of Middlesex, Optician,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eighth day of September, in the year of our Lord
One thousand eight hundred and sixty, in the twenty-fourth year of Her
reign, did, for, Herself, Her heirs and successors, give and grant unto me, the
said Geminiano Zanni, Her special license that I, the said Geminiano Zanni,
my executors, administrators, and assigns, or such others as I, the said
Geminiano Zanni, my executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times there-
after during the time 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 "IM-
PROVEMENTS IN APPARATUS FOR ROASTING," upon the condition (amongst others)
that I, the said Geminiano Zanni, by an instrument in writing under my hand
and seal, 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..

page_text: NOW KNOW YE, that I, the said Geminiano Zanni, do hereby declare
the nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement, reference being had to the Drawing hereunto annexed, and to
the letters and figures marked thereon, that is to say :-
This Invention of improvements in roasting apparatus is applicable to
all kinds of apparatus in which joints of meat, poultry, or game are exposed to
the action of the naked fire and require to be basted. The Invention has for
its object to baste the meat continuously and with regularity, and to continue
this operation while the meat is exposed to the fire. To effect this object, the
fat or dripping from the meat is allowed to fall into the dripping pan, from
whence it is conveyed along a suitable channel to a vessel or reservoir, from
which it is raised by means of my improved apparatus.
In the accompanying Drawing I have shewn three views of a meat screen,
with my improvements adapted thereto.
Fig. 1 is a front elevation, some of the parts being shewn in section ;
Fig. 2 is a transverse vertical section; and Fig. 3, a horizontal section of the.
same. a, a, a, is a meat screen of the ordinary form, and provided with a pan
b, into which the fat and dripping from the joint is allowed to fall, and is con-
veyed by the pipe c to the vessel or reservoir d, in which is mounted a pulley
or band wheel e. Around this wheel e is passed a band, chain, or strap f
which carries small scoops or buckets 9, 9, and passes round another band
wheel or pulley h at the upper part of the apparatus. This upper band wheel
h is actuated by means of clockwork, a smoke-jack, or in any other convenient
manner, as shewn at A, in Fig. 1, and by this means rotary motion is commu-
nicated to the endless chain of scoops or buckets g,g, which by dipping into
the liquid fat or dripping in the vessel d below, will raise the liquid and pour
it into a tumbling plate i, which is mounted on centres and is provided with a
weight j. After one of the buckets g has poured its contents on to the tumbling
plate i, it passes down, and in so doing pushes back the tumbling plate i,
which, immediately the bucket has passed will, by means of the weight j, be
brought back into its original position. The tumbling plate guides the drip-
ping into a gutter or channel k above, from whence it will run into a perforated
channel or dish placed above the meat. By keeping the endless chain of
scoops or buckets 9, 9, in action while the meat is roasting, the meat or joint
will be kept properly basted, a regular and constant supply of dripping being
maintained.
Although the Invention is shewn as applied to a single joint meat screen,
such as is ordinarily used in private families, it is also applicable to other kinds

page_text: of roasters in which several joints are, roasting at the same time. When the
self-acting basting apparatus is applied to a spit roaster or other apparatus on
which several joints may be roasting simultaneously, the dripping pan should
be divided into several compartments, so constructed and arranged as to
receive the dripping from every joint of meat separately. From these separate
compartments of the dripping pan, the dripping will be conducted to distinct'
and separate receptacles, each of which will be provided with an elevating
apparatus, such as that above described, so that each joint may be basted with
its own fat or dripping.
Having.now described my Invention of "Improvements in Apparatus for
Roasting," and having explained the manner of carrying the same into effect,
I claim as the Invention secured to me by Letters Patent as aforesaid, the,
apparatus herein set forth for basting meat while roasting.
In witness whereof, I, the said Geminiano Zanni; have hereunto set
my hand and seal, the Eighth day of March, in the year of our 1
Lord One thousand eight hundred and sixty-one.
Witness,
