Application filed December 28, 1917. Serial No. 209,238.
To all whom it may concern:
Be it known that 1, WILLIAM SOHUTTLER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Locomotive-Arch Brick, of which the following is a specification.
The present invention relates to a refractory brick or tile adapted for use within locomotive fire-boxes, for the purpose of forming a deflecting baffle or arch within the same.
The principal objects of the invention are to provide a brick which will be easy of installation and removal, and which will be of such character as not to become readily mutilated or destroyed in shipping.
A further object of the invention is to form a passage extending crosswise of the brick and from edge to edge thereof, which will serve to permit of the escape of heat from the body of the brick in a uniform manner and the entrance of cold air into the body of the brick in a uniform manner, thus making a uniform heating and cooling of the brick in accordance with temperature changes.
The invention further consists in the features of construction and combination of parts hereinafter described and claimed.
In the drawings:
Figure 1 is a plan view, showing a plurality of the brick of the present invention in place upon water tubes, and with one of the bricks in section;
Fig. 2, a section on line 22 of Fig. 1 on a somewhat enlarged scale, and with a portion of the brick broken away;
Fig. 3, a section on line 3-3 of Fig. 1, with the Water tube removed; and
Fig. 4:, a perspective of the brick.
In the art towhich the present invention relates, tiling or brick composed of fireclay are positioned upon water tubes within a locomotive fire-box for the purpose of forming a bafiie or deflecting arch so as to more efficiently mix the products of combustion and lessen the amount of smoke, as well as increasing the heating efficiency. Owing to the frequent opening and closing of the fire-box door, temperature changes take place within the firebox. It happens that these bricks, becoming heated throughout, are chilled around their outer portions by the cold air coming through the open fire door, but the center remaining hot, there is an expansion of the brick at the center and a contraction around the outside, with the result that the brick cracks. This causes it to burn out more quickly and fall into the fire-box. In the present invention, a simple construction eliminates the difficulty of cracking from this cause.
Referring now to the drawings, particularly to Figs. 1 and 2, the brick are shown as mounted upon water tubes 5, which extend longitudinally of the fire-box of a locomotive in a manner well known to the art. Each of the bricks, which are designated by the general numeral 6, have grooves 7 formed along opposite sides thereof to allow them to partially embrace the water tubes and rest thereon, as shown in Fig. 2.
The portion of the brick 8 which depends below the tube is tapered as shown in the drawings to provide sloping walls 9, which serve to mix the gases as they traverse the bottom of the brick. Extending crosswise of the brick and in a direction crosswise of the tube 5 is a passage 10 extending from edge to edge of the brick, and, as shown in the drawing, opening partially above the water tubes.
The heat transmitted to the underface of the brick can pass out from the body of the brick through this passage 10 and into the fire-box, so that an even radiation of heat from allportions of the brick is obtained. When the fire-box is opened, the cold air coming in on top of the brick flows through this passage 10 and is communicated to all portions of the brick, causing a uniform cooling thereof. In this manner, the center of the brick does not remain in a heated condition while the outside cools, but all portions are heated and cooled in a uniform manner. This prevents an expansion of one portion of the brick and a contraction of another, which results, as previously stated, in a cracking thereof.
The brick is extremely cheap and simple of manufacture and is of such form as to enable it to be readily shipped without becoming mutilated.
As shown in the drawings, there are two of the passages 10 with a central web 11 be? tween them. This reinforces the brick so that. it is strong enough to withstand the strain when suspended between the water tubes. The brick can be installed and removed with the same case as is attendant upon baffle brick now used in locomotive tion crosswise of the brick and from side to fire-boxes. side thereof, said passage permitting a uni I claim: form heating and cooling of all portions of 10 A locomotive arch brick, comprising a the brick whereby an even expansion and body configured along opposite edges torest contraction of the entire body of the brick against Water tubes, said brick having a pasis obtained, substantially as described. sageformed therein extending in a direo- WILLIAM SCI-IUTTLER.
