page_text: LETTERS PATENT to Charles Askew, of 27, Charles Street, Hamp-,
stead Road, in the County of Middlesex, Coppersmith, and David
Ritchie, of 42, Willaim Street, Regent's Park, in County of Mid-
dlesex, Engineer, for the Invention of "IMPROVEMENTS IN ROASTING
MACHINE FOR MEAT, POULTRY, OR GAME OF ANY KIND, TO BE WORKED BY
SPRING JACK MOVEMENTS OR BY THE ORDINARY SMOKE-JACK."
Sealed the 20th April 1858, and dated the 9th February 1858.
PROVISIONAL SPECIFICATION left by the said Charles Askew and David
Ritchie at the Office of the Commissioners of Patents, with their Petition,
on the 9th February 1858.
We, CHARLES ASKEW, of 27, Charles Street, Hampstead Road, in the
County of Middlesex, Coppersmith, and DAVID RITCHIE, of 42, William Street,
Regent's Park, in the County of Middlesex, Engineer, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN ROASTING MACHINE FOR
MEAT, POULTRY, OR GAME OF ANY KIND, TO BE WORKED BY SPRING JACK MOVEMENTS
OR BY THE ORDINARY SMOKE-JACK," to be as follows:-
These improvements in the roasting machine consists in arranging the guide
slides in the sides of the roasting oven, for the convenience and ease of taking
out of the oven the meat, poultry, or game, and in the sliding door at the side
of the oven, for taking out the basting spoon or spoons.
In carrying out this improved Invention, many mechanical movements may
be imployed, from the horizontal or vertical spit in the oven to the basting

page_text: spoon or spoons. As a mode of effecting this, a small bevel cog wheel is fixed
on the horizontal or virtical spit, and another horizontal sharft is fixed on the
side of the ovan, with a small bevel cog wheel, to suit the bevel cog wheel on
the spit, to which a endless chain is attached with one or more basting spoons,
as the case may be required, and as the spit revolves it causes the sharft on
the side of the oven to revolve, by which the basting spoon or spoons is carried
from the dripping well in the bottom of the oven to the top of the oven, and
as the basting spoon or spoons arrive at the top of the oven they emptyes there
contents into a recess, and the dripping continually fall over the roasting meat,
'poultry, or game.
This improvement in self-basting machine may be made to attach togather
one, two, or more machines side by side, or one on the other, by having a
granulated wheel fixed on the spit of each oven, and worked by means of
endless chain from one granulated wheel to the other, and the whole can be
worked by the spring clock movements. or by the ordinary smoke jack.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Charles Askew and David Ritchie in the Great Seal Patent
Office on the 26th May 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, CHARLES
ASKEW, of Number 27, Charles Street, Hampstead Road, in the County of
Middlesex, Engineer, and DAVID RITCHIE, of Number 42, William Street,
Regent's Park, in the County of Middlesex, Engineer, send greeting.

One thousand eight hundred and fifty-eight, in the twenty-second year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us, the
said Charles Askew and David Ritchie, Her special licence, that we, the said
Charles Askew and David Ritchie, our executors, administrators, and assigns,
or such others as we, the said Charles Askew and David Ritchie, our execu-
tors, 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 ex-
pressed, 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 ROASTING MACHINES FOR MEAT,
POULTRY, OR GAME OF ANY KIND, TO BE WORKED BY SPRING JACK MOVEMENTS, OR BY
THE ORDINARY SMOKE-JACK," upon the condition, (amongst others) that we, the

page_text: said Charles Askew and David Ritchie, our executors or administrators, by
an instrument in writing under our, 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 im-
mediately after the date of the said Letters Patent.
NOW KNOW YE, that we, the said Charles Askew and David Ritchie,
do hereby declare the nature of our 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):
Our said Invention refers to a mode of arranging several mechanical move-
ments in such a manner that they shall be employed as spit or spits, both
horizontally and vertically in a screen oven, and which said mechanical move-
ments are geared in and over the same with shafts, bevel, pinion, and other
toothed wheels, which are affixed to proper bearings, so as to allow the same
to freely work; and such several agencies are operated upon and worked with
an endless chain or chains or such like appliances, by the means of either
spring jack movements, the ordinary smoke-jack or other power, turning the
same wholly round; and are so constructed that two or more of the said
roasting machines can be placed at work side by side, or over or on the top of
the other.
And for the better understanding our said improvements, we will now pro-
ceed to detail the nature thereof, reference being bad to the Drawings annexed,
in which the same letters apply to like parts throughout.
DESCRIPTION OF DRAWINGS.
Figure 1 is a front and interior view of our improved roasting machine,
showing the general arrangements of the screen oven. A, A, is a horizontal
shaft, fitted at one end with a coupling box and pin fastening, and the other is
the driving end, with the necessary shifting wheels and pulleys for enabling
the same to be put in motion from the jack spring or other, moving powers.
The same is attached and affixed with bracket bearings to the side of the
screen oven, and the coupling box enables the spit and shaft to be fixed or
moved at pleasure. B is a driving cog or pinion wheel, keyed on the shaft A,.
which an endless chain works on, off, or around pinion wheel C, rotating the
shaft E, and which carries a cog wheel at the end, and which shaft also carries
three, or more bevel wheels, acting on a like number F, F, F, in a vertical
position, which vertical wheels are turned -round-simultaneously, and to which
are affixed the split hook end shafts, on which are placed the articles for

page_text: roasting; G, G, are two standard bearings, affixed and bolted on to the top of
the screen oven, on which a horizontal shaft works by means of a cog wheel,
and on which also a pinion wheel H is keyed on, for carrying the endless chain
I over the same, and to which endless chain are affixed the basting buckets
J, J, J. As the shaft E revolves, the cog wheel L and the pinion wheel H
are in motion working the chain L, and raising and lowering the service
basting buckets from the well N at the bottom of the screen oven to the
basting recess at the top. O shows the wheel on the shaf A, with projecting
arms pressing on an eccentric P, which raises the basting spoon Q through
orifice R at the top of the screen oven; S is a partition in the pan, at the
bottom of the screen oven, preventing the gravies mixing; T is a door at the
back of the screen oven; U is a compartment for depositing plates and dishes
for the purpose of warming; V shews a pump for raising the material for
basting.
Figure 2 is a top view of the screen oven. A is a perforation, to 'admit
the basting buckets to pass through to discharge their contents into service
recess B; B, B, B, are also service recesses, for basting either meat, poultry,
.or game.
Figure 3 is a side end view of the screen oven. A shows the position of
the guide slides to the bracket bearings, for placing or removing the spit;
B is a spring for keeping the lever C that works the basting spoon in its proper
position; D is a latch, for holding down and keeping the horizontal spit in its
position; E shows the compartment for placing the plates, dishes, &c., for
warming; F is the door at the side of the screen oven, for the purpose of
removing the basting spoon, as more clearly shewn in Figure 1.
Having thus fully described our said Invention, we would wish it to be
understood that we do not limit ourselves to the precise details herein
described, in placement of our several mechanical arrangements, or the
materials or dimensions, as they may be modified, but what we proclaim as our
Invention is,
Firstly, the horizontal coupling shafts at the side of the screen oven, with
the bracket bearings for placing and removing the spit and shafts at will.
Secondly, the arrangement of the endless chain from the pinion or cog
wheel on the coupling shaft to the pinion or cog wheel on the driving shaft,
with its bevel wheels geared into like wheels on the vertical spit hooks, as
affixed on the top of the oven, the working of the shaft carrying a pinion cog
wheel, which works any number of basting buckets that may be required on
the endless chain from the well at the bottom of the oven to the top, as shewn
in Figure 1.

page_text: Thirdly, the door and spring C and B at the side of the screen oven, as
shewn in Figure 3, for keeping the shaft in its proper position, for the con-
venience of taking out the basting spoon or cup; also the latch D, for keeping
in position the horizontal spit; and also a pump or pumps attached to the
oven for basting.
Fourthly, the signal bell on jack or clockwork movement, for giving
notice to the attendant when the clockwork or jack movement power is
about stopping, and requires to be rewound; and the sliding frought under
top of oven.
Fifthly, the partitions in the pan of screen oven for the separation of the
gravies, and the general arrangement of the whole.
In witness whereof, we, the said Charles Askew and David Ritchie,
have hereunto set our hands and seals, this the 8th day of April,
in the year of our Lord One thousand eight hundred and fifty-
eight.
