Improvements in or connected with Cooking or Heating Apparatus,
more especially intended for Infusing and Manipulating Coffee or
the like in large quantities.
I, EBENEZER BOYES, of Albert Road, Peckham, in the County of Surrey,
Wholesale Coffee Dealer, do hereby declare the nature of this invention to be as
follows:-
The invention relates to improvements in or connected with cooking or heating
apparatus more especially intended for infusing and manipulating coffee or the
like in large quantities.
In carrying the invention into effect a vessel of considerable capacity and
furnished with a cover is employed preferably formed of earthenware and sur-
rounded by a metal casing constituting a water jacket and this vessel is mounted
upon trunnions in a suitable skeleton frame formed as a stand or with feet
if desired furnished with wheels or casters so that it may be readily moved
about.
Fixed upon one of the trunnions is a toothed wheel which gears with a pinion
fixed upon a shaft mounted in bearings in the frame and provided with a crank
handle or any other suitable arrangement of gearing might be employed by the
aid of which the shaft may be rotated and the vessel thereby turned upon its
axes in order to pour off or decant the infusion of coffee at the times desired.
In order to retain the vessel in its tilted or inclined position during the
pouring operation and thus relieve the operator, the toothed wheel or a separate
ratchet wheel fixed with the trunnion or with the shaft is engaged by a locking
device or pawl adapted to be easily manipulated to lock or release the vessel at
the times desired by means of a treadle or otherwise.
The earthen vessel is provided at a suitable position below the mouth and
upon the interior of the vessel with a transverse bar or fence the office of which
is to keep back the grounds or the like during the pouring operation hereinafter
referred to so that the liquor will come off clear.
The jacket of the vessel is provided with a pouring lip and in order to avoid
the accidental spilling of the liquid during the pouring operation and to enable
said liquid to be decanted into separate vessels the said lip has attached thereto
a flexible chain of funnels or the like leading one into the other and adapted
to be readily separated and bodily removed for cleansing or other purposes and
it is desirable that the upper one of the chain of funnels be provided with a
strainer to arrest any floating particles in the liquor.
It is of course necessary to lift the lid or cover of the vessel from time to
time and inasmuch as to perform this operation by hand would involve con-
siderable labour it is desirable to provide mechanical means for doing this work
and for this purpose the cover or lid has fixed thereto a rod or spindle which
passes through a hole formed in a bar or frame extending across the vessel and
upon this rod is mounted upon an axis of motion a cam which bears upon the

page_text: bar or frame and is provided with an operating lever or handle by throwing over
which the lid may be easily raised and so. held during the pouring operation and
this device is so arranged that it may together with the cover be entirely removed
to give free access to the vessel for cleasing purposes.
Beneath the vessel is provided a gas or charcoal fire which effects the general
heating or boiling of the contents of the vessel and an auxiliary heating device
which may consist of a gas burner is so arranged as to follow the movements of
or travel with the vessel or a gas or other heating device may be suspended from
axes carried by the case or jacket at a short distance' from the bottom or it
might be suspended from the trunnions so as to automatically retain its level and
heat the bottom or side of the case or jacket according to its position.
When it is desired to boil the contents of the vessel a pipe is led from the
upper part of the jacket-down towards the bottom of the vessel and this pipe
is removably connected with the device so that it may be taken off when desired."
When the vessel is of comparatively small capacity the toothed gearing and
crank handle for tilting the same may be dispensed with and a simple handle
substituted therefor by means of which the vessel may be turned on its axes in
the required manner.
In, cases, where the apparatus is to be used on board ship it may be desirable to
mount the vessel in gimbals or the like.
By the means herein before described a convenient and practical form of
apparatus is obtained by the aid of which large quantities of coffee or other
material may be manipulated without difficulty.

Improvements in or connected with Cooking or Heating Apparatus,
more especially intended for Infusing and Manipulating Coffee or
the like in large quantities.
I, EBENEZER BOYES, of Albert Road, Peckham, in the County of Surrey,
Wholesale Coffee Dealer, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement: --
The invention relates to improvements in or connected with cooking or 'heating
apparatus more especially intended for infusing and manipulating coffee or the
like in large quantities.
In carrying the invention into effect a vessel of considerable capacity and
furnished with a cover is employed preferably formed of earthenware and sur-
rounded by a metal casing constituting a water jacket and this vessel is mounted
upon trunnions in a suitable skeleton frame formed as a stand or with feet.
Fixed upon one of the trunnions is a toothed wheel which gears with a pinion.
fixed upon a shaft mounted in bearings in the frame and provided with a crank.
handle or any other suitable arrangement of gearing might be employed by the
aid of which the shaft may be rotated and the vessel thereby turned upon its
axes in order to pour off or decant the infusion of coffee at the times desired.

page_text: In order to retain the vessel in its tilted or inclined position during the
pouring operation and thus relieve the operator, the toothed wheel or a séparate
ratchet wheel fixed with the trunnion or with the shaft is engaged by a locking
device or pawl adapted to be easily manipulated to lock or release the vessel at
the times desired by means of a treadle or otherwise.
The earthen vessel is provided at a suitable position below the mouth and
upon the interior of the vessel with a transverse bar or fence the office of which
is to keep back the grounds or the like during the pouring operation hereinafter
referred to so that the liquor will come off clear.
The jacket of the vessel is provided with a pouring lip and in order to avoid
the accidental spilling of the liquid during the pouring operation and to enable
said liquid to be decanted into separate vessels the said lip has attached thereto
funnel or the like adapted to be readily separated and bodily removed for
cleansing or other purposes and it is desirable that the funnel be provided with
a strainer to arrest any floating particles in the liquor.
It is sometimes necessary to lift the lid or cover of the vessel from time to
time and inasmuch as to perform this operation by hand would involve con-
siderable labour it is desirable to provide mechanical means for doing this work
and for this purpose the cover or lid has fixed thereto a rod or spindle which
passes through a hole formed in a bar or frame extending across the vessel and
upon this rod is mounted upon an axis of motion a cam which bears upon the
bar or frame and is provided with an operating lever or handle by throwing over
which the lid may be easily raised and so held during the pouring operation and
this device is so arranged that it may together with the cover be entirely removed
to give free access to the vessel for cleansing purposes.
Beneath the vessel is provided a gas or charcoal fire which effects the general
heating or boiling of the contents of the vessel and an auxiliary heating device
which may consist of a gas burner is so arranged as to follow the movements of
or travel with the vessel or a gas or other healing device may be suspended from
axes carried by the case or jacket at a short distance from the bottom or it
might be suspended from the trunnions so as to automatically retain its level and
heat the bottom or side of the case or jacket according to its position.
When it is desired to boil the contents of the vessel a pipe is led from the
upper part of the jacket down toward the bottom of the vessel, and this pipe
is removably connected with the device so that it may be taken off when desired.
When the vessel is of comparatively small capacity the toothed gearing and
crank handle for tilting the same may be dispensed with and a simple handle
substituted therefor by means of which the vessel may be turned on its axes in
the required manner.
In cases where the apparatus is to be used on board ship it may be desirable to
mount the vessel in gimbals or the like.
And in order that the said invention may be more clearly understood and
readily carried into effect I will proceed aided by the accompanying drawings
more fully to describe the same.

In the several figures in which like parts are indicated by similar letters of
reference Figures 9, 11 and 12 are drawn to an increased scale and Figure 6 to
a further increased scale with respect to the other figures of the drawings.
Referring to Figures 1 to 6 a represents the vessel or container which is of
considerable capacity and preferably formed of earthenware and provided with
a removable cover or lid and this vessel a is by means of a flange a¹ resting
upon a bead a mounted within a metal casing or jacket a³ of larger diameter
the space between the parts being filled with water constituting a water jacket
surrounding the vessel ".
The casing and consequently the vessel a is provided with trunnions or
axes a a* mounted in bearings 62 carried by the upper ends of standards b¹
bolted to a base plate 6 provided with a rim or foot 6* which rests upon a table
or counter f.
Fixed upon that one a³ of the trunnions is a toothed wheel which gears with
a pinion fixed upon a short shaft c mounted with capability of revolving in
bearings provided in one of the standards b' and this shaft c is furnished with a
crank handle, or any other suitable device might be employed, by the aid
of which the shaft may be rotated and the vessel a thereby turned upon its
axes a 5* and more or less tilted as shown at Figure 5 in order to pour off or
decant the infusion of coffee or other contents thereof at the times desired.
To facilitate the pouring operation the earthen vessel a and the jacket a³ are
provided with lips or spouts a* and in order to hold in place the lid a² during
the tilting operation metal clips a are provided, at their lower ends attached
to the jacket and at their upper ends cranked to clip over the rim or edge
of the lid or cover a³.
In order to retain the vessel in its tilted or inclined position during the
pouring operation and thus relieve the operator, a toothed, notched or ratchet
wheel is fixed with the shaft c and engaged by a locking device or pawl 5
pivotally mounted upon the standard 61 and by means of a rod or link c con-
nected with a treadle by which means the pawl may be easily manipulated to
lock or release the vessel a at the times desired whilst leaving the operators
hands free, or the pawl might be otherwise operated if desired.
The earthen vessel a is provided at a suitable position below the mouth or
spout a and upon the interior of the vessel with a transverse bar or fence a the
office of which is to keep back the grounds or the like during the pouring opera-
tion so that the liquor will come off clear.
In order to avoid the accidental spilling of the liquid during the pouring
operation and to enable said liquid to be decanted into separate vessels the
lip a* of the jacket has suspended therefrom a funnel as adapted to be readily
separated therefrom and bodily removed for cleansing or other purposes and
this funnel is provided with a strainer or grating to arrest any floating particles
in the liquor which escape the fence a².
Beneath the vessel a the jacket a³ is dished or recessed and axially of said

page_text: recess is provided a Bunsen burner d, or it might be any other heating contrivance
which is carried by the base plate and surrounded by a screen or shield 63 and
this burner is supplied through a branch controlled by a cock from the
service pipe d³ and this burner d effects the general heating of the vessel a in
the first instance after which the supply is turned off and the required degree of
heat is maintained by the auxiliary heating device hereinafter described.
The trunnion a* is formed hollow and tapered and ground into the bearing ba
like the plug of a cock and it is provided with a way a** for the admission of a
supply of gas which is conducted thereto by a branch controlled by a cock d³
from the service pipe.
The gas flows into the hollow trunnion a* and is thence conducted by a pipe e
through an air mixing chamber el to a semi-circular auxiliary burner e perforated
with a number of jets so arranged that when the vessel a is tilted the flames from
said jets will impinge upon that part of the casing or jacket as to which the water
therein naturally gravitates and by these means the auxiliary burner e is caused
to follow the movements of the vessel a.
The vessel a is provided with a steam pipe a leading nearly to the bottom
thereof and passing through a perforation in the lid or cover a² and this pipe
beyond the lid is bent downward and at its end is tapered to removably fit and
form a steam tight joint with a correspondingly shaped fitting a¹0, shown more
particularly at Figure 6, leading from the steam space of the jacket a³ and
thus the contents of the vessel a may be boiled when desired whilst the steam-
pipe a may be readily removed when not required or to facilitate the taking
off of the lid a².
The jacket is fitted with a screw filler «**, a water gauge all to give an
indication of the general level of the water therein and with a cock a¹² by the
aid of which the contents thereof may be drawn off when required.
In the example given at Figure 7 the auxiliary burner e is by the pipe c³
pivotally suspended from the trunnion * and supplied with gas through a
flexible pipe e* and said burner is thus caused to automatically retain its level
in the normal position of the vessel or to follow the tilting movement thereof
and take up a position best suited to heat the water within the jacket a³ as
shown by the dotted lines.
In the example given at Figures 8 to 12 is shown a means of lifting the lid of
large vessel a unprovided with a spout when it is desired to pour the contents
thereof and inasmuch as to perform this operation by hand would involve con-
siderable labour it is desirable to provide mechanical means for doing this work.
For this purpose the cover or lid a² has fixed thereto a rod or spindle a which
passes through a hole formed in a bar or frame a extending across the vessel a
and fixed to the jacket by screw bolts a¹5 provided with fly heads and upon
the upper end of the rod a3 is mounted upon an axis of motion a¹6 a cam a¹7
which bears upon the bar or frame a and is provided with an operating lever
or handle as by throwing up which as shown at Figures 10 to 12 the lid a² may
be easily raised and so held during the pouring operation whilst by unscrewing
the bolts a the entire device together with the lid may be removed to give
free access to the vessel a for cleansing purposes.
In the example given at Figures 13 14 and 15 a modified form of tilting
apparatus is shown.
In this case a frame 8 is by means of a short horizontal shaft pivotally
mounted upon an independent standard c* and normally fixed in a horizontal
position by means of a clamping plate 10 removeably fixed with the standard c*
by means of a screw bolt el furnished with a fly-head.
Mounted with capability of revolving in the frame is a threaded shaft or
spindle furnished with crank handles and mounted with capability of
travelling upon the screw c is a nut c¹ to which is pivotally connected one end
of a link the other end of which is pivotally connected to a crank & fixed
upon the trunnion a³.

page_text: by rotating the left hand crank handle the nut c¹ will be caused to travel upon
the screw c towards the right hand thereby gradually tilting the vessel until
the nut reaches the end of its traverse as indicated at Figure 15 when by slacking
the bolt and turning the clamping plate co out of the way the entire frame c
may be turned on its axis in the direction of the arrows Figure 15 until the
position of the crank handles is reversed whereby the nut and the vessel a
will be carried back to their initial positions as shown by the dotted lines in
Figure 15 when by fixing the clamping plate 10 again in position the above
operations may be repeated.
When the vessel a is of comparatively small capacity the toothed gearing
herein before described with respect to the previous figures and the device lastly
described may be dispensed with and a simple lever or handle substituted there-
for by means of which the vessel may be turned on its axes in the required
manner.
In the example given at Figure 16 the apparatus is generally the same in
character as that hereinbefore shown and described with respect to Figures 1 to 5
but in this case means are provided whereby the removal of the vessel bodily
from its bearings is facilitated.
For this purpose the bearings 62 are formed open topped and the trunnion 7.5*
is extended beyond its bearing and the tapered or plug like end thereof is fitted
into a boss formed on the upper end of an elbow a furnished with a regulating
cock and provided with a union 8 connecting the same with the branch
by unscrewing which the entire device may be lifted out of its bearings.
In cases where the apparatus is to be used on board ship it may be desirable
to mount the vessel in gimbals, or the like.
and
By the means herein before described a convenient and practical form of
apparatus is obtained by the aid of which large quantities of coffee or other
material may be manipulated without difficulty.
