COMBINED STEAM'AND HOT-WATER HEATER.

SPECIFICATION forming part of Letters Patent 1\T o. 681,226, dated August 27, 1901. `f i i Application filed April 20, 1901. `Seriallll'o. 56,726. (No model.)

T @ZZ whom t may concern.:

Connecticut, have invented certain new and useful Improvements in aCombined Steam e 1 l andHot-Water Heater, of which the following is a specification.

My invention relates to a combined hotwater and steam heater; and it has for its object the provision of means whereby the ordinary boiler now in use for steam-heating pure l poses only may be so divided that it may be utilized both as a steam-heater and a hot-water heater.

In the sectional steam-boiler now employed ,a the` sections or manifolds thereof are connected in assembling the boiler by through-r bolts, and in the steam-dome of the boiler and at its lower part these manifolds are y made to communicate with each other by what are known in the trade as push-nipa ples, which are castings or fixtures connecty ing one manifold with another manifold in order to afford free steam and water connec-` tion between all of the sections of which the 1"* 1 boiler is composed.

to employ steam for heating one part of a` t building and hot water for heating another i It frequently happens that it is desirable part of said building; and myinvention is designed particularly for enabling'both the a x steam and hot-water systems to beutilized, as desiredin;the same building and with but the use of a single boiler.'

My inventionmay be carried into effect in many ways, and the main object thereof is to so divide steam-boilersof `various kinds now e in use that one part of the boiler maybe utilized as a steam-heater 'and the other part thereof as a hot-water heater.

Incarrying out the invention I may employ aset of push nipples, having dial phragms or partitionsfor dividing the boiler into sections, or what are known as blind sections or manifolds may be employed, or a manifold dividing the boiler into the desired sections, said manifold having a longitudinal a, partition for accomplishing the same purpose,

maybe employed, the invention not being t limited to any specific device for carrying it i y into edect.

is a View similar to Fig. 5, representing another modiication in which one of the sections or manifolds is provided with a longitudinal diaphragm or partition.

Like characters designate similar parts throughout the several views.

Referring to the drawings, the numeral `designates a common form of sectional steamboiler to which my invention is shown applied, and the numerals 12 the manifolds or sections which are united by longitudinal rods or bolts 13 in assembling the boiler. These manifolds are hollow to afford a circulation of the water employed for generating steam, and the apparatus is provided with a steam-dome 14 with lateral pipes 15 and with a vertical pipe 16 for containing water. A water-supply pipe 17, containing a valve 17', by which the entrance of water is regulated, and the usual return-pipe 1S will also be found illustrated in Figs. 1 and 2.

l Designated by the numeral 19 is .an im-` proved form of push-nipple, which serves `to divide the heating apparatus illustrated into sections A and B, respectively, the section A serving as a steam-heater and the section B as ahot water heater. 4 lnipples are each provided with a diaphragm These push- 19', and when placed in the openings provided for their. reception in the sections or manifolds 12,'as illustrated in Figs. 1 and 2, serve to divide the apparatus into the two compartt ments A and B, respectively, above speciiied,

`in the former of which steam is generated for the purpose of heating by that agent and in the latter of whichjhot water is relied `upon as the heating agent. N

Connected'to the hot-,water section B of the apparatus are the usual supply andreturn pipes 22 and` 23, respectively, and leading from both sections of said apparatus are pipes Irs 24 and 25, respectively, for supplying steam and hot water to the parts of the building desired. Y

While nipples of a particular kind are illustrated, it is distinctly to be understood that the invention is not limited to the form of nipple shown, for other forms containing a diaphragm or partition may be employed as substitutes without departure from the scope thereof.

The usual grate 26 for receiving fuel is illustrated inFig. ,2, and the products of combustion emerge from the apparatus through the iiue 27 and pipe 28, leading to the chimney.

In Fig. I have illustrated a modification in which the push-nipples, with diaphragms, are dispensed with, and what is termed a "blind section or manifold 29 is inserted between two of the manifolds 12 for the purpose of dividing olf or separating one of the sections of the apparatus from the other.

In the modication illustrated by Fig. 6 a section or manifold 30, having a longitudinal partition 31, is employed for eecting the same purpose.

Push-nipples 32 of ordinary form are illustrated in the several views for connecting the steam-dome of one section of the apparatus with the various manifolds in the section A, and similar push-nipples are also employed for permitting a circulation of the hot Water in the section B, as illustrated in Fig. 1.

It frequently happens that it is deemed necessary or desirable to utilize one section of the apparatus for steam heating purposes and the other section for hot-water heating, as above stated, and by dividing the boiler in the manner set forth I am enabled to accomplish these results with ease and facility.

While the invention is shown on atype of apparatus in which the sections or manifolds are arranged vertically, it is distinctly to be understood that it is not limited thereto, for it may be employed with various forms of boilers now on the market, whether of the vertical, horizontal, or other types, or with sections cast solid.

The blind nipples 19 containing the diaphragms or partitions 19 may be applied to any section of the boiler required without departure from the invention, and either the rear or front section of said boiler may be utilized as the hot-water section or the steamsection, if desired.

Having thus described my invention, what I claim isl. In aheatingapparatus,the combination, with a boiler, of closed nipples fordividing said boiler into sections, one of said sections to be utilized for generating steam fora steamheating system, and the other of said sections as a means for supplying hot water to a hotwater heating system.

2. The combination, with a boiler composed of separate sections, of closed nipples for dividing said sections so that one part of the boiler may be utilized as a steam-heater andthe other part of said boiler as a hotwater heater.

3. In an apparatus of the class specified, the combination, with a boiler composed of sections or manifolds, of means for uniting said manifolds; and closed push-nipples for separating a part of saidV manifolds fron another part thereof. v

4. The combination, with a boiler composed of tubular sections or manifolds, each of said manifolds having a series of openings, of means for connecting one manifold with another manifold, to permit a circulation of the heating agent; and closed push-nipples for dividing off one set of manifolds from another set, whereby the boiler is separated into sections, one of which may be employed as a steam-heater and the other as a hot-water heater.

5. The combination, with a boiler composed of manifolds perforated at dierent points to permit a circulation of the heating agent, of open nipples inserted in said perforation; and means located between two opposing open nipples for dividing said boiler into sections, whereby one part of the boiler may be utilized as a steam-heater Vand the other part thereof as a hot-water heater.

6. The combination, with a boiler composed of sets of manifolds, of means for uniting said manifolds; means for connecting the manifolds to afford a circulation of the heating agent and closed nipples for dividing one set of manifolds from another set, so that the sections of the boiler may be utilized for different purposes.`

7. The combination, with a boiler composed of sections, of closed nipples for uniting said sections; means for separating one section from another section, and supply and return pipes connected with each section.

8. The combination, with a boiler composed of tubular manifolds, of a set of nipples for connecting these manifolds at dierent points; and a set of blind nipples for dividing the boiler into sections, one section to be employed as a hot-Water heater and the other section as a steam-heater; and supply and return pipes for both sections.

9. The combination, with a boiler composed of manifolds, of open nipples uniting certain of said manifolds at different points;- and closed or blind nipples dividing one set of manifolds from another set 0f manifolds.

10. In a combined steam and hot-water boiler the combination, with manifolds having openings at their upper ends and other openings in their lower ends; of push-nipples connecting one manifold with another, and located in said openings; and push-nipples having diaphragms located in the openings of two adjacent manifolds, and serving to separate one set of manifolds from another set, thereby to divide the boiler into sections for utilization as steam and hot-water heaters.-

11. The combination, with a series of ver- IIO IZO

tubular sections, each section having an opening for the passage of Water, of a parti- 1o tion adapted to be located between the op posing openings, substantially as specified.
