THOMAS I. RANKIN, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO 'FI-IE ABRAM COX STOVE COMPANY, OF SAME PLACE.

WATER-H EATER.

SPECIFICATION forming part of Letters Patent No. 663,363.dated December 4, 1900.

Original application led April 8, 1899, Serial No. 712,252. Divided and this application filed September 12,1900. Serial No.

To all whom it may concern.'

Beit known that LTHOMAS I. RANKIN,a citizen of the United States, residing in Philadelphia,Pennsylvania,have invented certain Improveinents in Vater-I-Ieaters, (beinga division of au application for patent filed by me on April 8, 1899, under Serial No. 712,252,) of which the following is a specification.

The object of my invention is to construct a gas-heater for heating water which can be used in place of the ordinary water-back of a range or can be used in addition to said waterback, as desired.

rlhis application is a division of an application filed by me on the Sth day of April, 1899,

Serial No. 712,252.

In the accompanying drawings, Figure 1 is a longitudinal sectional View of my improved water-heater on the line 1 1, Fig. 2; and Fig. 2 is a transverse sectional view on the line 2 2, Fig. 1.

A is a water-chamber made of cast metal and preferably in a single piece. In the present instance it is quadrangular in form, having side bars a a and cross-bars ct at top and bottom and intermediate cross-bars d2. All the bars are tubular and are so shaped and arranged as to provide for the ready circulation of the water to be heated. By making the bars tapered in cross-section accurate castings can be readily produced. The crossbars a2 are staggered, as shown, and the end bars d are corrugated to correspond therewith. 'Ihis arrangement deflects the products of combustion, so that all portions of the casting will be subjected to the direct action of the same.

The water-chamber Ais inclosed within a casing B. This casing in the present instance consists of a lower frame B, a cap-plate b, sides b, and end plates b2. The cap-plate b is flanged and the side plates are secured to the said Flange and to the bottom plates by screwbolts or rivets. In the present instance the side and end plates are made of a single sheet of ornamented metal lined with a non-couducting material, so that heat will be retained in the water-heater.

(No model.)

The cap-plate b has a fine-opening c, above which is ashort stack C to carry off the waste 5o products of combustion.

Forming part of the lower frame B' is the cap d of the burner D. Arms d connect the cap with the portion of the frame secured to the casing. Secured to the capd isa troughshaped bottom section D', the edges of this section fitting snugly against the iianges of the cap, as shown in Fig. 2, and screw-bolts cl2 pass through the cap and trough-section, holding the parts together.

The cap d has a series of perfor-ations z for the escape of gas. Agas-pipe I is connected to one end of the burner, as shown in Fig. 1. The pipe is provided with the usual valve (not shown) and an air-valve i. Air and gas are mixed at the valve il, and the mixture enters the burner, escaping through the perforations and mixing with a certain quantity of air entering through the space between the ange of the frame B and the depending 7o cap b.

At each upper corner ot the water-chamber A are threaded bosses e e, and in the lower cross-bar al are threaded bosses e' e'. The water-pipes E E, leading to the boiler, are coupled to one of the upper bosses and'to one of the lower bosses. The openings in the other two bosses are closed by suitable plugs.

By providing the bosses as shown the waterheater can be used either right or lett handed. 8o

My improved water-heater can be attached to the circulating-pipes of an ordinary range using a boiler and water-back or may be used independently of the water-back, if desired.

As soon as the water in the boiler or other receptacle reaches a certain temperature the gas can be turned off, thus economizing in the fuel. The water-heater may be coupled to a supply-pipe at any point desired and 9o Water heated independently of a range or a water-heater at the range.

I claim as my invention- 1. A casting having tubular corrugated side bars and tubular cross-bars communieating with the tubular side bars, said crossbars being staggered, in combination With a casing inclosing said casting and a burner under the said casing, substantially as described.

2. The combination of acasting made in a single piece and having tubular corrugated side bars and tubular cross-bars communicating with the tubular side bars, the said cross-bars being staggered and tapered, with a casing inclosing the said Watercl1amber, and a burner under the said casing, substantially as described.

3. The combination ot' a'Water-chamber, a casing inclosing said Water-chamber, said casing consisting of an open base-frame, a top plate having a flue -opening therein and flanged, with a side plate or plates secured to the base-frame and the flanges of the top plate, a longitudinally-arranged burner directly under the casing, the cap of the burner forming part of the base-frame of the casing, the trough-shaped lower portion of the burner being secured to the cap, and a gas pipe coupled to the said-burner, substantially as described.

4. The combination of a water-chamber, a casing in which the Water-chamber is mounted, said casing having a base-frame, a burner situated under the casing, the cap of lsaid` name to this specification in the presence of two subscribing witnesses.
