Improvements in Hot Water Heaters.
I, TIMOTHY HOLLAND, of Number 89 Lake Street in the City of Chicago in
the State of Illinois, one of the United States of America, Merchant, do hereby
declare the nature of this invention and in what manner the same may be
performed, to be particularly described and ascertained in and by the following
statement :-
My invention relates to warming apparatus for residences; and the object of my
improvements is to adapt a hot water heater to a fire place in conjunction with a
pair of loop radiators serving as the jambs thereto and as a support for the mantel
piece, the whole constituting an ornamental, convenient and economic apparatus.
I attain this object by the means illustrated in the accompanying drawings, in
which
Figure 1 is a front elevation of an apparatus of the class named, embodying my
invention.
Figure 2 is an enlarged vertical section taken on the line 2-2 of Fig. 1.
Figure 3 is an enlarged horizontal section taken on the line 3-3, of Fig. 1.
Figure 4 is a detail showing an enlarged horizontal section taken on the line 4-4
of Fig. 1.
Figure 5 is a front elevation of the water back with the fire grate and front wall
removed, the hood or cover over the fire place being in vertical section.
Figure 6 is a vertical section through the flues, it being taken on the line 6-6
of Fig. 3.
In the drawings, A designates the water-back, which is surmounted by a water-
dome or hood, B. Said back and hood are hollow, and preferably cast separately
and connected by nipples a (shown in dotted lines, Fig. 4), so that the water can
freshly circulate from the back to and through the hood.
The interior face-side of the water back is concave, and provided with a
flange a', or equivalent device for supporting the fire basket A', and grate A' in
connection therewith, as seen in Fig. 2; and the front which forms the complement
to the water back and encloses the fire basket A¹, is provided with doors b b for
introducing the fuel, doors or openings 661 for affording access to clean and shake
the grate, and sliding dampers for regulating the draft, the doors being pro-
vided with mica panels and being similar in construction and general appearance to
the corresponding parts of a base burner heating stove.
The rear of the hood is provided with a flue opening B¹ at one side, which com-
municates with a down-flue B' and the latter connects through an opening B³ at the
bottom, with an up-flue B' which enters the chimney. The rear part of the hood
and water back containing the flues, is adapted to be set back in the fire place and
under the shelf of a mantel with the up-flue B' corresponding in position with the
himney leaving the front of the hood and the part enclosing the fire basket and
oors for introducing fuel to project out into the room to be warmed, so that the
adiation from the front will be out in the room somewhat more than the heat from
fire place.
At the sides of the water back A, next to the wall of the room and in place of
ie jambs of a fire place, I arrange two loop radiators C, composed of a series of
ops, which are connected with one another and with the water back at the bottom,
y nipples c, so that water from the supply pipe c' can enter the loops and water back.
he top of the radiator loops is similarly connected one with the other by nipples c
d with the hood B by means of a pipe C¹.
The heated water rises to the hood and thence through pipe C to the top of the
diator loops, causing a circulation of the cooler water from the bottom or lower

page_text: part upward, and away through circulating pipes C' to other radiators (not shown)
which are to be located in other rooms of the same building and connected in the
ordinary manner so as to include them with radiators C in one connected system
for warming the different rooms.
The radiator loops are provided with vertical fing D cast on the rear side of the
loops; and the water back also has a similar fin D' on each side. Said fins come
together when the parts are connected and from vertical flúes d at the back of the
radiators through which the air is drawn from the floor and deflected outward by
the mantel shelf E, made of a marble slab, which is placed on the top of the
radiator.
:D
By providing an opening e in the wall of the building, a supply of fresh air may
be admitted from the outside just under the radiators so that it will be warmed and
discharged into the room, this introducing a fresh supply of warm air for
ventilation.
The front part of the water back projects inside of the line of the wall, against
which the fins D come when the apparatus is in place, and the space intermediate
this part of the water back and the radiator loops can give off radiation of heat in
the same manner that an ordinary stove would if placed close to the wall; so that
the warmth produced from this part of the apparatus is comparatively greater
than that which could be produced from the consumption of a given amount of
fuel in a fire place. By deffecting the products of combustion through the down
flue B and through the up-flue B, which are surrounded by the water space A, a
further saving of heat is effected without in the least interfering with the draft,
which will be required to be checked by closing the dampers as soon as the
apparatus has become warm. The heat thus saved is utilized by means of the
radiator loops. and goes to augment that which would be saved and used for warming
the room by the heater alone.
Having now particularly described. and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I.declare that what I
claim is:
1. In a mantel hot water heater, the combination with an enclosed fire pot, of a
concave water back, a hollow water hood over the water back, a down flue in the
water back communicating through the hood with the fire pot, an up-flue in the
water back communicating with the down-flue at the bottom, nipples connecting
the water back and hood, a leop radiator on each side of the water back, connected
by nipples with the bottom portion of the water back and by nipples and a pipe
with the top of the hood, and a mantel shelf supported on the top of said loop
radiators substantially as specified.
2. In a mantel hot water heater, the combination with an enclosed fire pot
provided in front with a door and draft regulator and in the rear with a concave
water back, of a water hood over the fire pot and connected by nipples with the
water back, a down flue and an up flue in the water back communicating with one
another at the bottom and with the fire pot under the hood at the top of the
up-flue, a loop radiator on each side of the water back, connected therewith at the
bottom and with the hood at the top, for causing a circulation of water through
said loops, water back and hood, substantially as specified.
3. In a mantel hot water heater, the combination with an enclosed fire pot, of a
water back, a water hood over the fire pot, a loop radiator on each side of the
water back, and a mantel shelf surmounting the same, the loops of said radiators
being connected with said water back and water hood so as to afford a circulation
of water therein, substantially as specified.
4. In a mantel hot water heater, and in combination, an enclosed fire pot, a water
hood over said fire pot, flues communicating with said fire pot, and having a mean-
dering course through said water back, a radiator composed of a series of separate
vertical loops on each side of said water back, extending above the said hood and
surmounted by a mantel shelf, said radiator loops, water back, and hood, being

page_text: specified.
80 88 to afford a circulation through the same, substantially as
5. In a mantel hot water heater of the class described, the water back provided
with a fin on each side, a series of separate radiator loops at each side provided
with fins adapted to be used in conjunction with one another and the fins on the
water back to form air flues behind said loops, and a mantel shelf mounted on said
radiator loops and adapted to deflect the heat from said air flues outward from the
walls, as specified.
