;OFFLICE- 130m CHARLEY ,B'AILLY, OF. REAL, MINNESOTA, ASSIGNOR or: ONE-HALF TO SAMUEL BARRY, or FENTON, MINNESOTA.'
of Real, in the county of Clay and State of Minnesota, have made certain new and useful Improvements in Heat-Screens for Steam- (ihests, of which the following is a specifica- -tion.
My invention relates to certain novel features of construction. and to combinations of The object of my invention is to prevent the condensation of steam in steam-chests, due in part to the reduction in pressure in passing from the governor to the steam-chest and the consequent loss of heatand to the further loss of heat due to the radiation from the steam-chest covering. My invention is intended to prevent this radiation, and with this object in view I provide a heat-screen A (shown in Figs. 2 and 3) and composed of sheets of non-heat-conducting material arranged on the internal face of the steam-chest I cover and comprising from within outward a sheet of canvas A, a sheet of asbestos'B,a
core of pine wood C, a second sheet of asbes- I tos D, a second sheet of canvas E, a sheet of fiber F, and a sheet of perforated metalG,
I and I secure the heat-screen to the cover H of the steam-chest I by means of screwthreaded bolts J, passing through the screen andinto the inner faces of the steam-chest The sheets A, B, C, D, and E are of a' size to correspond with the internal faces of the steam-chest cover, while the sheet of fiber F is provided with depending portions L, closely conforming to the internal, faces of the side and end walls of the steam-chest I,
' and provided at one end with a slot M to receive the valve-rod N, attached to the valve N.
To assemble the parts, the screen A is secured to the steam-chest cover H by means of the bolts J, and the cover, with the attached screen, is placed in and over the open ingof the steamchest, and the cover is se- Specification of Letters Patent. Application filed. April 15, 1905. Serial No; 255,729.
Patented March 20, 1906.
cured-in place by the usual screw-threaded bolts 0.
By the use of the above-described screen I obtain a much greater efficiency with a small amount of fuel and water than is possible to obtain without its use, even by an increased consumption of fuel and a greater amount of water.
It will be evident that the screen'ma be used on any type of engine and on any orm of steam-chest by varying its-shape to conform to the shape and size of the steam-chest. I do not limit myself to the exact order of. placing the sheets together, since it is evident that such order may be varied within wide limits, nor do. I choose to limit myself to the material of which the different sheets are composed, as it is obvious that other nonheat-conducting material may be used with similar results.
Having thus described my invention, what I claim as new, and-desire to secure by Letters Patent, is-
1. The combination of a steam-chest, a cover for the chest, a heat-screen for the cover comprising a core of wood, sheets ofasbestos on eachl-face of the core, sheets 'of canvas covering the asbestos, a sheet of fiber covering theinternal face of the internal sheet of can vas, and provided with depending portions, a perforated metallic sheet upon the face of the sheet of fiber and within the depending por; tions, and screw-threaded bolts for securing the heat-screen to the steam-chest cover.
2. The combination of the steam-chest, a cover for the chest, a heat-screen for the cover comprising a core of wood, alternate sheets.
of asbestos and canvas on either face of the core, a sheet of fiber on the internal sheet of canvas and provided with depending portions, a perforated metallic sheet on the sheet of fiber and within the depending portions, and means to secure the screen tothe steam-chest cover.
3. The combination of a steam-chest, a cover therefor, a heat-screen for said cover comprising a core of wood, alternate sheets of asbestos and canvas on either face of the core, a perforated metallic sheet on the internal face of the heat-screen, and means for se curing the screen to the cover.
4. The combination of a steam-chest, a
cover. therefor, aheat-screen for thecover .1 comprlslng a core of wood, sheets .ofnonheat-conducting material on either face of the its face, and means for securing the screen to core, and means for securmg the screen to the the cover.
