JAMES J. JOHNSTON, OF COLUMBIANA, OHIO, ASSIGNOR TO THE UNlTEI STATES IMPROVEMENT. COMPANY, (LIMITED,) OF SAME PLACE.

WASH-BOILER.

SPECIFICATION forming part of Letters Patent No. 266,835, dated October 31, 1852.

Application filed February 523. 1882.

To all whom it may concern Be it known that I, JAMES J. JOHNSTON, of Golnmbiana, in the county of Golumbiana and State of Ohio, have invented a certain new and useful Improvement in \Yash-Boilers; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

My invention relates to an improvement in wash-boi1ers; and it consists in making the bottom with a groove extending entirely around it, leaving a plane between the side walls of the boiler and said groove, and in forming a series of transverse grooves which communicate with first-mentioned groove, and in combining with said grooves a water-distributer consisting of two horizontal and parallel pipes connected to a pipe forming a tubular arch having a series of perforations therein, said horizontal and parallel pipes being adapted to tit insaid grooves, all of which will hereinafter more fully and at large appear.

To enable others skilled in the art with which my invention is most nearly connected to make and use it, I will proceed to describe its construction and operation.

In the accompanying drawings, which form a part of this specification, Figure 1 is a top view or plan of my improvement in wash-boilers. Fig. 2 is a side elevation of the same. Fig. 3 is a vertical and longitudinal section of the same at line w x of Fig. 1. Fig. 4is a vertical and transverse section at line y y of Fig. 1. Fig. 5 is a perspective view of the waterdistributer used in combination with my improvement in wash-boilers.

Reference being had to the accompanying drawings, A represents the body of the washboiler, which is constructed in the usual manner and of the ordinary form and of sheet tin or copper. The bottom B is formed with a groove, (J, extending entirely around the bottom, leaving a plane, D. between it and the outer wall of the body A, the outer edge of said plane having aflange, E, for securingthe bottom B to the body A. The bottom B is also furnished with transverse grooves F, which communicate with the groove O. The groove 0 and the grooves F are formed by means of (No model.)

dies, by what is known as the stamping pro cess, by which means several bottoms may be formed at a single operation. By having the groove 0 extending entirely around thr bottom it will greatly strengthen it longitudi nally, and will form a downward projectior tor entering the opening in the top of the stove and serving as a means for holding the boilei in proper position on the stove, as indicated in Fig. 4. The transverse grooves F, which communicate with groove 0, give transverse strength to the bottom, and by the combina tion of the groove 0 and grooves F great stitfness and strength are secured in the bottom with increased heating-surface.

The water-distrilmter A consists of twc horizontal and parallel pipes, G, to which is attached an arched pipe, H, havingin the arch a large number of perforations. Said water distributer should be so constructed that its pipes G will rest in the groove 0, as shown by dotted lines in Fig. 4, or rest in two of the grooves F, as shown by dotted lines in Fig. 3. By this means the water-distributor will be held in a fixed position in the boiler. The groove O and the grooves F, communicating with each other, will cause a longitudinal and transverse circulation of the water under the clothes in the'boiling process, and thereby t'acilitate said process, and also avoid all liability of burning or scorching the clothes, so common to the ordinary boiler. The waterdistributer A, (the ofiice of which is well understood in connection with wash-boilers,) when combined with the groove (3 and the grooves 1*, will cause a thorough circulation of the boiling water among the clothes, and thereby greatly facilitate the process of boiling the clothes and assist in washing them.

I am aware that a water-distributor combined with a wash-boiler is well known, and I am also aware that bottoms for wash-boilers with transverse grooves and a plane is old, and therefore do not claim the said devices, broadly; but

What I do claim is 1. In a wash-boiler, the bottom B, having groove 0, extending entirely around it, with transverse grooves F communicating therewith, in combination with the water-distribu- A, consisting of horizontal pipesG G and transverse grooves F, communicating therezical curved pipe H, having perforations I. with, and plane D, substantially as herein de- 10 l pipes G G adapted to fit in the groove 0 scribed, and for the purpose set forth.
