CHILLS EMPLOYED IN CASTING CORNER BLOCKS, DOVETAIL GROOVES, AND OTHER
PARTS OF METAL BEDSTEADS AND OTHER LIKE ARTICLES, IN FRAMES FOR
CARRYING SUCH MOULDS, AND IN TUBES FOR THE PILLARS OF BEDSTEADS AND

Sealed the 16th May 1862, and dated the 20th November 1861.
PROVISIONAL SPECIFICATION left by the said Edward Peyton and
William Fothergill Batho at the Office of the Commissioners of Patents,
with their Petition, on the 20th November 1861.
We, EDWARD PEYTON, of Birmingham, in the County of Warwick, Manu-
facturer, and WILLIAM FOTHERGILL BATHO, of the same Place, Manager, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN THE
MOULDS OR CHILLS EMPLOYED IN CASTING CORNER BLOCKS, DOVETAIL GROOVES, AND
OTHER PARTS OF METAL BEDSTEADS, AND OTHER LIKE ARTICLES, IN FRAMES FOR
CARRYING SUCH MOULDS, AND IN TUBES FOR THE PILLARS OF BEDSTEADS AND OTHER
LIKE ARTICLES," to be as follows:-
Our Invention consists in constructing the moulds.or chills in manner here-
after explained.
The moulds are composed by preference of two principal parts or boxes,
each of which will lift away from the other after the casting is completed.

page_text: We will describe first one part or box and then the other, supposing only two
parts to be used. The first part consists of two cheeks of iron, between which
is inserted what we term a bed, equal to the length or thickness of the intended
dovetail grooves; the cheeks and bed are bolted together. Upon the bed a
chill or metal mould containing the counter parts of the two dovetail grooves,
and of the inner side of the pillar block is inserted; and this chill is also
equal in length or thickness to that of the intended block, and dovetail grooves,
an aperture is made in the cheeks of the box for the pillar on which the casting
is to be effected to pass through. The second main part or box consists also
of two cheeks, between which a metal, chill or mould is fixed, which chill,
when the two boxes are placed together, completes the pattern or shape of
the corner block to be cast. Apertures are formed in the cheeks of the second
part, which correspond with those in the cheeks of the first for the reception of
the pillar on which the casting is to be effected. When any raised pattern or
device is to be cast on the outer part of the blocks which will not allow of the
casting leaving the moulds, then the chills must be formed in pieces, and
loose pieces may be added, which will come away with the casting and drop off
or be readily removed. The gate for pouring in the metal is formed in the
thickness of one of the cheeks in each of the boxes or main parts. Although
we have described the two boxes as formed of three pieces, yet they may,
though not generally so, advantageously be formed in one piece. The moulds
or chills for casting on other parts to the pillars are formed similarly to those
described, only the internal chill or mould must be varied according to the
form required to be produced. We sometimes make the internal chills, those
which fit into the boxes, in several parts, and clamp them together; at other
times we find it sufficient to form them in two parts only, one being inserted
in each of the boxes.
Again, instead of the internal mould or chill for the dovetails and inner side
of the pillar block being only equal in length or depth to that of the intended
dovetails and blocks, the chill may be made to pass through the cheeks of the
box, and may be composed of one, two, or more pieces.
In casting large corner blocks, in order to obtain lightness and ornament,
we sometimes use sand or loam cores in conjunction with the chill, and run
the sand out or not after the casting is completed through the centre of the
pillar or otherwise.
. We construct the frame for carrying the chills of a cast-iron planed bed, on
to which the chills are bolted; supported horizontally by two standards held
together by stretchers; there are journals, at the "ends of the planed bed,
working into suitable bearings in the standards, so that the bed is free to

page_text: revolve and carry the chills into the most convenient-position for. pouring.
The bed may be made double to carry two sets of chills...
The above frame, with the addition of suitable slides to carry the necessary
chills in the case of French ends, is applicable for casting stump and French
ends complete.
In casting dovetails on to the sides and ends of bedsteads, we use chills or
boxes open at top and bottom, which are placed on the frame before described,
and by means of it can be turned into such a position as will bring the gate on
the under side, and thereby do away; with grinding.
Our Invention further consists in forming the pillars for bedsteads and other
like articles at those parts where the corner blocks and dovetails or other
projections are to be applied by casting of increased diameter to that of the
other parts of the pillar.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Edward Peyton and William Fothergill Batho in the Great
Seal Patent Office on the 20th May 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, EDWARD
PEYTON, of Birmingham, in the County of Warwick, Manufacturer, and
WILLIAM FOTHERGILL BATHO, of the same Place, Manager, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twentieth day of November, in the year of our Lord
One thousand eight hundred and sixty-one, in the twenty-fifth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us, the
said Edward Peyton and William Fothergill Batho, Her special licence that
we,, the said Edward Peyton and William Fothergill Batho,. our executors,
administrators, and assigns, or such others as we, the said Edward. Peyton and
William Fothergill Batho, our 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 "INPROVE-
MENTS IN THE MOULDS. OR CHILLS EMPLOYED IN CASTING CORNER BLOCKS, DOVETAIL
GROOVES, AND, OTHER PARTS, OF METAL BEDSTEADS AND OTHER LIKE ARTICLES, IN
FRAMES FOR CARRYING SUCH MOULDS, AND IN TUBES FOR THE PILLARS OF BEDSTEADS
AND OTHER LIKE ARTICLES," upon the condition (amongst others) that we, the
Said Edward Peyton and William Fothergill Batho, or one of us, our execu

page_text: tors or administratörs, by an instrument in writing under our, or their,
or one of our or their hands and seals, should particularly describe and ascer-
tain 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 we, the said Edward Peyton and William Fothergill
Batho, do hereby declare the nature of our 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, reference being had to the
Drawings hereunto annexed, that is to say :-
Our Invention consists in constructing the moulds or chills in manner here-
after explained.
The moulds are composed by preference of two principal parts or boxes,
each of which will lift away from the other after the casting is completed.
We will describe, first, one part or box, and then the other, supposing only
two parts to be used. The first part consists of two cheeks of iron, between
which is inserted what we term a bed equal to the length or thickness of the
intended dovetail grooves; the cheeks and bed-are-bolted together. Upon
the bed a chill or metal mould containing the counterparts of the two dovetail
grooves and of the inner side of the pillar block is inserted, and this chill is
also equal in length or thickness to that of the intended block and dovetail
grooves, an aperture is made in the cheeks of the box for the pillar in which
the casting is to be effected to pass through. The second main part or box
consists also of two cheeks, between which a metal chill or mould is fixed;
which chill, when the two boxes are placed together, completes the pattern or
shape of the corner block to be cast: Apertures are formed in the cheeks
of the second part which correspond with those in the cheeks of the first, for
the reception of the pillar on which the casting is to be effected. When any
raised pattern or device is to be cast on the outer part of the blocks which
will not allow of the casting leaving the moulds, then the the chills must be
formed in pieces, and loose pieces may be added which will* come away with
the casting, and drop off, or be readily removed. The gate for pouring in
the metal is formed in the thickness of one of the cheeks in each of the
boxes or main parts: Although we have described the two boxes as formed of
three pieces, yet they may be formed in one piece. The moulds or chills for
casting on other parts to the pillars are formed similarly to those described,
only the internal "chill" or mould must be varied according to the form
required to be produced.

page_text: Again, instead of the internal mould or chill for the dovetails and inner side
of the pillar block being only equal in length or depth to that of the intended
dovetails and blocks, the chills may be made to pass through the cheeks of
the box, and may be composed of one, two, or more pieces.
:
In casting large corner blocks, in order to obtain lightness and ornament,
we sometimes use sand or loam cores in connection with the chill, and run the
sand out or not after the casting is completed through the centre of the pillar
or otherwise.
:
We construct the frame for carrying the chills of a cast-iron planed bed on
to which the chills are bolted supported horizontally by two standards held
together by stretchers. There are journals at the ends of the planed bed
working into suitable bearings in the standards, so that the bed is free to
revolve and carry the chills into the most convenient position for pouring.
The bed may be made double to carry two sets of chills.
The above frame, with the addition of suitable slides to carry the necessary
chills in the case of French ends, is applicable for casting stump and Frencli
ends complete.
In casting dovetails on to the sides and ends of bedsteads, we use chills or
boxes, open at top and bottom, which are placed on the frame before described,
and by means of it can be turned into such a position as will bring the gate
on the under side, and thereby do away with grinding..
Our Invention further consists in forming the pillars for bedsteads and other
like articles at those parts where the corner blocks and dovetails, or other
projections, are to be applied of increased diameter to that of the other
parts of the pillar.
Figure. 1 of the accompanying Drawings is a longitudinal. section of. a
mould or chill constructed. according to our Invention; Figure 2 is a cross
section through the line x, y, of the same; and Figure 3 is a plan thereof, also
partly in section. a is the upper, and b is the lower portion of the chill or mould
fitting accurately on one another, and between which the corner blocks and
dovetail grooves
are cast; c is the dovetail block laid in a recess, formed in
the lower portion 6 of the chill; wherein it is free to move within certain
limits, as will be presently described; e is a lever, having its fulcrum at f, the
short end of which bears against the under side of the dovetail block c, while
the long end thereof extends outside the chill, and carries an abutment g;
h, h', are levers, free to move with the shafts.i, i, and extending upwards round
the chills; each of these levers. terminates in hooks; & is an eccentric lever;
jointed to the lever h', whereby it is caused to become engaged or disengaged
with the lever h', and thus act as a clamp for holding the parts of the chill

page_text: together. The shafts i, i, terminate at each end in right and left-handed
screws, and, work through nuts 1, 7, in recesses at the lower part of the chili;
m, m, are pieces of metal or "draw backs," inserted in the chills and cor-
responding with the pattern of pillar being cast. Any number of these pieces
may be used in fact where elaborate pillars are required. The whole of
the chills may be made in pieces according to the pattern or device to be
produced.
:
The operation is as follows:-Supposing the two portions of the chills to be
together with. the dovetail block c, in position at the bottom of the lower
portion 6 of the chill; then on metal being poured into the chill it will run
round the sand core, as seen in Figure 1, and on the dovetail block c, whereby
the dovetail grooves and corners are formed; now to remove the casting from
the chills, which is effected as soon as the metal has sufficiently set, turn the
lever k, which disengages the books on the levers h, h, and allows them to be
opened or divided, thereby causing the two ends of the lower portion 6 of the
chill to recede, at the same time the lever h' acts against the abutment 9,
depresses the long end of the lever e, raises the short end t thereof, and with it
the dovetail block and pillar out of the lower portion of the chill; the upper
portion a of the chill is then removed, and the casting is raised. On the
upper portion a and pieces m, m, being replaced, and the two ends of the
lower portion of the chills being brought together by the levers h, h¹, the
chills are ready to receive a fresh casting.
Figure 4 is a side elevation; Figure 5 is an end view with a portion of the
chill, removed, and Figure 6 is a plan of a chill for casting the corner pieces
solid instead of hollow as before described; c is the dovetail block as before.
In this case the loose pieces or drawbacks are dispensed with, but in some
cases they may be used; in other respects the construction is similar to that
before described, and similar letters of reference in the previous Figures refer
to corresponding parts in these.
Figure 10 is a side elevation; Figure 11 is a longitudinal_section, and
Figure 12 is a plan of a chill or mould for casting the dovetails on to the
side and end rails; a is the upper, and bis the lower chill or mould, d is the
dovetail block inserted between the upper chill a and the lower chill b; e is a
screw pin or stud for securing the dovetail block; f. is the gate by which
molten metal is run into the chills. The piece is removed after the metal
has sufficiently set by raising the upper chill a. . The chills may be secured
together during the casting by clamps or otherwise.
Figure 13 is an end elevation; Figure 14. is a side elevation, and Figure
15 is a plan of a chill or mould for casting dovetail grooves on to the "French"

page_text: ends of bedsteads. a is the upper and 6 is the lower chill; c is the angle iron
inserted between the upper and lower chill; d is the dovetail block and c is
the gate by which molten metal is run into the mould. The dovetail block is
inserted by raising the upper from the lower chill and the casting is remioved
by a similar process.
Figure 16 is a side elevation; Figure 17 is an end elevation, and Figure
18 is a plan of a frame constructed according to our Invention for carrying
the chills or moulds; a is the planed bed into which the chills are bolted;
this bed is supported by standards b, b, which are united by girders or stretchers
c, c. The bed a is mounted on trunnions or journals which are free to turn
in bearings d, d, formed in the standards b, b; these trunnions extend outside
the standards and carry at one or both ends, a crank bandle e whereby
the frame is caused to turn or oscillate; is a pin inserted in a hole formed
in the end of the crank and entering a corresponding aperture formed in one
of the standards whereby the frame is kept steady when desired. When the
frame is used for casting "French" ends the cross slides g, g are fitted in
addition to the bed a. The operation is as follows:-Supposing one end of a
French bedstead to be under manufacture, the chills-h, hare bolted to the
planed bed a and the frame is kept secure by the crank e and pin f, the rods
are then inserted in the chills and the frame is turned or set at an angle by
means of the crank e for the convenience of pouring in the molten metal.
And having now described the nature of our said Invention and in what
manner the same is to be performed, we declare that we claim as our
"Improvements in the Moulds or Chills employed in Casting Corner Blocks,
Dovetail Grooves, and other Parts of Metal Bedsteads and other like
Articles and in Frames for Carrying such Moulds,
First, the construction of chills or moulds by preference in two principal
parts or boxes containing a dovetail block or bed and core of sand or loam
rounded, and on which the molten metal is run to form dovetail grooves, and
hollow pillar corners substantially in manner herein-before described with
reference.to Figures 1, 2, and 3 of the accompanying Drawings.
Second, the employment of machinery or apparatus for operating the chills
or moulds together with the employment of loose pieces or "draw backs" made
to act substantially in manner and for the purposes herein-before described
and illustrated in the accompanying Drawings.
Third, the construction of chills or moulds containing dovetail blocks for
casting the corner pieces solid as herein-before described with reference to
Figures 4, 5, and 6 of the accompanying Drawings.
Fourth, the construction of chills or moulds containing dovetail blocks for
