COMPLETE SPECIFICATION,
Improvements in Water-heating Systems.
I, JOHN PHILIP BENJAMIN SADTLER, of 813 South Howard Street, Baltimore,
in the County of Baltimore, and State of Maryland, United States of America,
Gentleman, 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 an improvement in water heating, and particularly to
a water heating cylinder.
The invention is designed to render the ready and quick use of water in a range
or water heating cylinder immediately upon the entry of hot water from the range
waterback into the cylinder, or when the range is cut off, to render the water
heated in the cylinder by heat applied at the bottom ready for immediate use
without circulating the water through the cylinder in the usual manner.
The prime object of the invention is to provide a water heating tank or cylinder
having the usual water circulating pipes, with a supplemental connection from the
boiler to the usual hot water discharge pipe, whereby hot water may be obtained
for use as it enters the hot water cylinder, or it may be heated therein without
heating a great body of water, or without circulating such heated water through
the cylinder and through the hot water discharge pipe in the usual manner.
A further object of the invention is to provide an ordinary water heating and
circulating cylinder, with means whereby hot water may be passed transversely
through or from the cylinder and render ready for immediate use simultaneously
with the heating of the water without the necessity of circulating the hot water
through the cylinder and hot water discharge pipe in the usual manner.
The invention consists in the novel construction and arrangement of parts, and
resides essentially in making a supplemental hot water connection from the
cylinder to the usual hot water discharge pipe, so that at whatever point in the
cylinder the water is of greatest heat, hot water may be drawn directly from
such point.
In the accompanying drawings forming part of this application
Fig. 1, is an elevation partly in section of an ordinary range hot water cylinder
connected to a water back showing my invention applied.
Fig. 1, is a similar view shewing the application of a gas burner for directly
heating the water in the cylinder.
Fig. 2, is a similar view showing the transverse pipe of Fig. 1, divided, and
without a hood.
Fig. 3, shows the transverse pipe divided, one end of which is enlarged to receive
the other end.
Fig. 4, is a like view showing a pipe suspending a hood over the induction pipe.
Fig. 5, is a sectional view of a cylinder showing a hood suspended at the bottom
of the boiler by a vertical pipe connected through the side of the cylinder to the
usual hot water pipe.
The same numeral references denote the same parts throughout the several
figures of the drawings.

page_text: 1, denotes an ordinary range hot water cylinder having the usual hot and cold
water pipe connections 2, 3 and 39 respectively.
The supplemental hot water pipe 4 is connected to the cylinder 1 lower down
or near the bottom of the boiler than is customary, and extends transversely
through the boiler. The pipe 4 has an opening 5 from which depends a hood 6,
as shewn in Fig. 1, and from the cylinder the pipe 4 communicates with the hot
water pipe 3, so that hot water may be consumed directly from the water back 4°,
without circulating through the cylinder in the well known manner. The hood 6
acts as a funnel in drawing water from the cylinder when the range is cut off and
the water is heated by the application of a gas burner 8, to the bottom of the
cylinder, so that the water may be drawn off at its highest temperature directly
from the source of heat, this is shewn in Fig. 1^.
Referring to Fig. 2, the supplemental transverse pipe is made in two sections,
one section 9, for hot water induction, and the other section 10, for hot water
discharge. These sections are readily screwed in from opposite sides of the
cylinder until their inner ends stand in close proximity, one above the other, near the
bottom of the cylinder. Or, as shown in Fig. 3, the ends of the sections 11 and 12
end opposite, one having an enlargement 13 to receive the end of the other section.
Both of these accomplish the same results as the contiguous transverse pipe in
Fig. 1 when connected to a water back.
In Fig. 4, is shown a pipe 14, extending through the center of the cylinder, and
provided with a depending funnel or hood 15 opening from the pipe. The induc-
tion pipe 16, extends into the cylinder and ends under said funnel or hood and
may carry cold water into the cylinder to be heated under the hood by a suitable
heater applied to the bottom of the cylinder.
Referring to Fig. 5, the usual hot water pipes 18 and 21 and cold water pipes 19
and 20 are employed. The induction hot water pipe 22, connected to the said
pipe 21 by a pipe 23, enters the boiler about midway its length. A hood 24 is
suspended inside and near the bottom of the cylinder by a vertical hot water
pipe 25 which opens into the hood and is connected through the side of the
cylinder to the hot water pipe 18 by a transverse discharge pipe 26.
I do not wish to be understood as limiting myself to a single transverse pipe or
to a pipe or pipes with a hood or funnel in as much as the pipes may be divided
or used in sections and the funnels dispensed with.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what I
claim is:-
1. The combination with a hot water cylinder having the usual induction and
discharge hot water pipes, and a cold water induction pipe, of a supplemental hot
water discharge pipe from the cylinder and connected to the said usual hot water
discharge pipe upon the outside of the cylinder, as set forth.
2. The combination with a hot water cylinder having the usual water circu-
lating pipes, of a supplemental hot water discharge pipe extending from the
inside of the cylinder and connected to the usual hot water discharge pipe upon the
outside of the cylinder, as set forth.
3. The combination with a hot water cylinder having the usual water circulating
pipes, of a supplemental hot water discharge pipe extending through and from the
cylinder in communication with the latter, and connected to the said usual hot
water discharge pipe upon the outside of the cylinder, as set forth.
4. The combination with a hot water cylinder having the usual water circulating
pipes, of a supplemental discharge pipe extending from the cylinder and con-
nected to the said usual hot water discharge pipe upon the outside of the cylinder,
and a hood opening into the cylinder and connected to the said supplemental pipe,
as set forth.
5. The combination with a hot water cylinder having the usual water circulating
pipes, of a supplemental discharge pipe extending from the cylinder and con-

page_text: nected to the said usual hot water discharge pipe upon the outside of the cylinder,
and a hood opening into the cylinder and connected to the said supplemental pipe,
as set forth.
6. The combination with a hot water cylinder having the usual hot and cold
water pipes, of a supplemental discharge pipe connected to the hot water discharge
pipe and extending into the cylinder, of an open hood in the boiler, and a vertical
pipe connecting the hood with the said supplemental pipe, as set.forth.
