Improvements in Frames or Cases for Oil and Gas Heaters.
We, JOHN HARPER AND COMPANY, LIMITED, of Albion Works, Willenhall
in the County of Stafford, Ironfounders and Manufacturers, and CHARLES
RETALLACK, of the same address Manager to the said Company, do hereby
declare the nature of this invention to be as follows: —
This invention relates to oil and gas heaters; and has for its object to greatly
facilitate the removal and replacement of the oil reservoirs and burners which are
carried thereby, or the gas burning appliance corresponding thereto when gas is the
fuel employed, from and within the frames or cases within which they are carried
when in use.
The above object. is effected, according to this invention, by forming the stand.or
base of each heater with an internal or inward flange on which a flange or shoulder
formed around the oil reservoir, or a corresponding flange or shoulder of a gas
burning appliance, rests, and preferably with an open framing, extending upwards
to about the level of the top of the burner, which supports a gallery to which the
lower end of the envelope, or portion of the case which surrounds the burner, is
fitted and by which it is carried; and the envelope is formed with lugs through
which screws are passed and screwed into the gallery to fix the envelope thereto.
The screws may be provided with suitably-shaped heads by means of which they
may be readily screwed up, and be unscrewed for removing the envelope from the
gallery. When it is desired to remove the oil reservoir and burner, or the gas
burning appliance, from the frame or case formed by the stand and envelope, the
screws are withdrawn and the envelope lifted off the gallery; the reservoir and
burner, or gas burning appliance, may then be readily lifted out of the stand
and the reservoir and burner, or gas burning appliance, may be as readily replaced
previously to refixing the envelope to the stand. The gallery is conveniently
formed of angle section, with the vertical member or flange of the angle upwards
and the horizontal member or flange outwards, and the bottom of the envelope is
placed upon the horizontal flange and around the vertical flange; but the horizontal
flange may be inwards, if desired, and the bottom of the envelope will then be inside
the vertical flange.
The open framing, aforesaid, allows of the reservoir, when such is used, being
re-filled without removing it from the case.
"
i
In lieu of forming an open framing with the stand, the envelope may be formed
as an open framing around its lower end, to allow for the passage of air to the
burner, and to allow of refilling the reservoir, when such is used, without first
removing it from the case; and in such an arrangement the part of the stand
on which the envelope rests is at about the level of the flange thereof on which
the reservoir, or gas burning appliance, rests; indeed it may rest on the same
flange.

We, JOHN HARPER AND COMPANY, LIMITED, of 'Albion Works, Willenhall
in the County of Stafford, Ironfounders and Manufacturers, and CHARLES
RETALLACK of the same address Manager to the said Company, 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:-
This invention relates to oil and gas heaters; and has for its object to greatly
facilitate the removal (for the purpose of cleaning or otherwise) and replacement
of the oil reservoirs and burners which are carried thereby, or the gas burning
appliances corresponding thereto when gas is the fuel employed, from and within
the,frames or cases within which they are carried when in use.
The above object is effected, according to this invention, by forming the stand
or base of each heater, with an internal or inward flange on which a flange or
shoulder formed around the oil reservoir, or a corresponding flange or shoulder of
a gas burning appliance, rests, and preferably with an open framing or support,
extending upwards to about the level of the top of the burner, which supports a
gallery to which the lower end of the envelope, or portion of the case which
surrounds the burner, is fitted and by which it is carried; and the envelope is
formed with lugs through which screws are passed and screwed into the gallery to
fix the envelope thereto. The screws should be provided with suitably-shaped
heads by means of which they may be readily screwed up, and be unscrewed for
removing the envelope from the gallery. When it is desired to remove the oil
reservoir and burner, or the gas burning appliance, from the frame or case, tlie
screws are withdrawn and the envelope lifted off the gallery; the reservoir and
burner, or gas burning appliance, may then be readily lifted out of the stand; and
the reservoir and burner, or gas burning. appliance, may be as readily replaced
previously to refixing the envelope to the stand.
The open framing or support, aforesaid, allows of access of air to the burner,
and allows of the reservoir, when such is used, being refilled without removing it
from the case.
In lieu of forming an open framing or support with the stand, the envelope may
be formed as an open framing or with open spaces around its lower end, to allow of
access of air to the burner, and to allow of refilling the reservoir, when such is
used, without first removing the envelope from around it; and in such an arrange-
ment, the part of the stand on which the envelope rests is at about the level of the
flange thereof on which the reservoir, or gas burning appliance, rests; indeed it
may rest on the same flange.
The burner may be exposed for lighting in any usual or convenient manner, such
as by opening a door forming a portion of the envelope and lifting the chimney
which is within it.
In order that the invention may be clearly understood we will now proceed to
describe a practical application thereof by the aid of the drawings herewith.
Figure 1 of such drawings is an elevation of a frame or case of an oil heater
constructed according to the modification' above described in which the envelope
is removably carried by an open framing or support which stands above the
base. Figure 2 is a sectional plan of the same taken on line xx of Figure 1.
Figure 3 is a vertical section thereof taken, as to one side, in a vertical plane
indicated by line yy of Figure 4, and as to the other side in a vertical plane
indicated by line y y of Figure 4; and
Figure 4 is a plan of the stand or base with the open framing or support, and

page_text: shews also a sectional plan, taken on line x², x¹ of Figure 3, of one half of the
envelope.
The oil reservoir and burner are shewn by broken lines Figure 3.
The stand or base A is formed with a flange a on which the reservoir B is
supported by its flange 6 resting thereon, the lower portion of the reservoir passing
down through the opening which is surrounded by the flange a.
The open
framing or support C which supports the gallery D on which the envelope E is
removably fixed consists, in the construction thereof shewn by the drawings, of &
number of short pillars c. These pillars are, conveniently, fixed to the base A by
means of screws d. These screws pass through lugs e of the pillars which rest upon
the flange a or top of the base, and such screws are screwed down into the base.
The gallery D is shewn by the drawings to be formed with a vertical portion f by
means of which it is fixed to the upper ends of the pillars c, screws g being passed
for such purpose through the pillars and screwed into the portion f. The gallery
is shewn also with a shoulder or horizontal portion m upon which the foot of the
envelope rests, and with a vertical flange h around which the foot of the envelope
is placed. The foot of the envelope is formed with lugs i through which screws k
are passed and screwed into the gallery to fix the envelope thereon. Two of these
lugs placed opposite to one another will usually be found sufficient. The heads
of the screws may be carried up to any height and be formed to any shape or
pattern which will enable them to be readily screwed up and unscrewed between
the finger and thumb, and thus the envelope may be readily unfixed and removed
for the removal and replacement of the reservoir B, and be as readily replaced
and refixed. The open framing or support C permits, however, as will be obvious,
of the reservoir being readily replenished from time to time without removal, the
inlet 7 being for such purpose placed in position opposite an opening between two of
the pillars c.
The base A, pillars c and envelope E, are usually greatly embellished with floral
or other design, the pillars being usually shaped as foliage. For the sake of
simplicity, however, we have shewn the parts plain in shape and without ornamenta-
tion. The top of the base is shewn as hexagonal, but it may of course be circular
or of other desired shape, and the envelope instead of being circular as shewn may
be of other desired shape.
The application of the invention to gas heaters, and the above-described
modification of the invention in which the lower portion of the envelope is
formed as an open framing or with open spaces therearound and is fixed direct
upon the stand or base instead of upon a gallery supported by an open
framing or support, will now be sufficiently obvious without further description
or illustration.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
1. A frame or case for an oil or gas heater, in which the envelope is detachably
fixed to a gallery supported from the base or stand by an open framing or open
support, or has its lower portion formed as an open framing or with openings there-
around and is detachably fixed direct to the base or stand, substantially as described,
for the purpose set forth.
2. A frame or case for an oil heater, in which the envelope is detachably fixed to
a gallery supported from the base or stand by an open framing or open support,
constructed substantially as described and shewn by the drawings herewith.
Dated this 23rd day of April 1905.
