BOILER FOR LOCOMOTIVES.
SPECIFICATION forming part of Letters Patent No. 226,694, dated April 20, 1880.
Application filed August 5, 1879. 4
To all whom it may concern Beit known that I, EUGENE HENRY ANGA- MAR, of New Orleans, in the parish of Orleans and State of Louisiana, have invented 5 a new and Improved Boiler for Locomotives,
of which the following is a specilication.
M v improvements relate to boilers that are applied beneath passenger-cars and supplied with hot water and steam from stationary boilxo ers at the end of the route, as more fully described in the Letters Patent granted to me November 27, 1877, No. 197,584.
The object of the present invention is to construct a boiler adapted for application to horse-cars now in use, so as to utilize such horse-cars without material changes; and my invention consists in a boiler made in two portions, separated by a mediate chamber, the water and steam spaces of the parts being The construction will be explained more particularly with reference to the accompanying drawings, and the invention pointed out in the claim.
In the drawings, Figure l is a plan view of 2 5 the boiler. Fig. 2 is a vertical longitudinal section on linexxot' Fig. 1, showing the boiler also in its relation to the car-wheels.
Similar letters of reference indicate corresponding parts.
'Ihe boiler is made in two parts, A B, of convenient sizeand form to place under the car-body, and between the parts A B is a space or chamber, a. The part A is deeper than the part B, and contains a lire-box or furnace, c, from which liues b extend to the space a..
The part B is tted with Lubes d, that extend from'the space a to the smoke-box e, and the part B is formed with a water-leg, f, one
4o side of which is formed by the wall of chamber a, and the leg f is connected by tubes g with the part A below the water-level. The steam-spaces et' the parts A B are connected by tubes h.
Upon the smoke box e and around the smoke-pipe the steam -dome 7c is placed. This dome is connected with the steam-space of A by pipes l. The steam -dome will project upward through the front platform of the 5o car'and the chimney will extend through the roo By the above-described construction, while the boiler is adapted for occupying the space beneath the car-body, it has ample water-space and a large extent of heating-surface, so that the initial pressure of the Water and steam when placed in the boiler may be readily maintained by a small tire.
It will be seen that the chamber a furnishes additional heating-surfaces, and the products 6o of combustion from the lfurnace, instead of passing straight to the chimney, are arrested in chamber a before passing to the dischargeues d. By these means the heat ot' the tire is utilized to the greatest possible extent to maintain the pressure and overcome thel deperdit-ion ot' heat or pressure occasioned by the exhaust of the engine.
By having the steam and Water spaces connected by double pipes attached to dii-ferent 7c points, as shown, the connection will not be interrupted by changes of level of the car, as when one pipe is choked the other will be free.
I am aware that it is not new to use steamchests or annular spaces around chimneys, or to use an auxiliary combustion-chamber between and connecting with two sections; but in these cases all the heat may pass directly through the chamber, the iiue-tubes being op- 8c posite, while in mine the heat is received by the back plate of the chamber, and must rise before escaping, my steam-dome being separate from boiler and connected with it by pipes,` so that chau ges of level will not interrupt circulation.
What I claim as new and of my invention 1s- A passenger-car boiler consisting ot' two parts, A B, intermediate chamber, a, smoke- 9c box e, and steam-dome k, arranged around smoke-stack and connected with steam-space, the part A having lire box and lines b c, and the part B having water-legf and tubes d, as shown and described.
