Description
NITED STATES PATENT BOILER-FRONT.
SPECIFICATION forming part of Letters Patent No. 286,174, dated January 4, 1881.
To all whom it may concern:
Be it known that we, THOMAS H. PARVIN and JOHN PARVIN, of Garmi, in the county of White and State of Illinois, have invented a new and Improved Boiler-Front, of which the following is a Specification.
The object of this invention is to provide a combined boiler-front and feed-Water heater, especially adapted to stationary boilers.
Ordinarily the fronts of horizontal cylindrical stationary boilers are made of single plates of iron, that permit a great and constant loss of heat by radiation from the fires, and that quickly burn out, crack, and become distorted.
Our invention is designed to remedy these defects; and it consists of a boiler-front constructed with hollow walls of boiler-plate or other suitable material, so as to form a waterchamber in which the boiler feed-water may pass and become heated on its passage to the boiler.
Figure 1 is a perspective elevation of the I device with a portion broken away to exhibit other parts. Fig. 2 is a horizontal section on line 0050, Fig. 1. Fig. 3 is a side elevation, showing the front supporting the end of a cylindrical boiler.
Similar letters of reference indicate corresponding parts.
In the drawings, A represents the boilerfront, consisting of outer and inner plates, A A, respectively held apart and joined at their edges by the edge-plates B, and about the fire-door and ash-pit openings by plates B, as shown, thereby forming a hollow front to be filled with the boiler feed-water. The front end of the boiler is designed to be supported in the semicircular depression 0 in the top of the boiler-front, and a a represent the fire-door openings, and b b the ash-pit openings. In one leg of this boiler-front A is an opening or 1')ipe-connection, d, to which the feed-water pipe is to be attached, while to the opening or connection f, or any other conven- Application filed May 13, 1880. (Model) ient place, the boiler-supply pipe h is to be attached. This front A supports the boiler, instead of masonry, is designed to be hollow throughout, and may be so constructed as to bear an equal steam-pressure with the boiler. Suitable valves for regulating the feed or supply of water to the boiler-front and the boiler are to be placed in the supply-pipes.
The feed-water passing through the front A may, if desired, be retained therein long enough to become heated to the boiling-point before entering the boiler, and at all times it keeps the said front from burning out or cracking, and also preserves a more moderate temperature in front of the boiler, thus avoiding the excessive radiation and consequent loss of heat common to ordinary boiler-fronts, and saving the expense and trouble of the ordinary feed-Water heaters. The legs 9 g of this front A, being hollow, serve as mud-drums for the deposit of the sediment from the' feed-water, and suitable openings or man-holes will be made in said legs 9 g for the removal of said deposit.
The connecting water-pipes can be attached to any points in the boiler-front that may be most suitable or convenient.
Having thus described our invention, we claim as new and desire to secure by Letters Patent- The within-described combined boiler-front support and water-heater, consisting of a box with a recess adapted to receive the end of a cylindrical boiler, provided with fuel and ashpit openings, communicating with an inletpipe and with the boiler, but detachable from the latter and from the walls of the fire-place, and constituting the front and supporting the end of the boiler, as set forth.
