CEMENT RING FOR HOT-AIR FURNACES.
SPECIFICATION'formin-g part of Letters Patent No. 534,145, dated February 12, 18 95.
I Application filed April 28, 1894- Sarlal No. 609,420- (No model.)
To all whom it may concern.-'
Be it known that I, ERNEST 0. FOX, a citizen of the United States, and a resident of Cleve- 1and,county of Cuyahoga, State of Ohio, have invented certain new and useful Improvementsin Cement Rings for Hot-Air Furnaces, of which I hereby declare the following to be a full, clear, and exact description, such as will enable others skilled in the art to which 'drawingsand more specifically pointed out in the claim.
In the accompanying drawings,Figure 1 is a vertical section through cast iron top of furmace, and steel radiator shell, showing cement ring and annular retaining plates. Fig. 2 is a similar section through retaining bolts. Fig. 3 is a perspective view of a section of the annular retaining plates.
In the drawings A is the top furnace plate of cast iron.
B is the steel radiator plate at the side of the furnace.
fi C is the shoulder into which said steel plate D is the cement ring.
E and F are concave annular plates fitting over the edges of the top and side furnace plates and curved to form a retaining trough for the cement ring D. These plates are semixed together by lugs and screws G and H,
and the sections by terminal lugs I connected *by bolts.
' An enlargement J serves to inclosethe lugs A upon the cast iron top plate A, and slotted openings K and L in the annular plates permit the passage of the holding bolts M connecting top and bottom'of furnace.
Hitherto the disadvantag'e found in steel plate radiator furnaces has been that a tight joint between the steel'plate and cast iron top could.- not be made, on account of the difficulty in fitting the rough castings to the steel,
and dangerous gases might be permitted to escape into the air chamber. The cement ring entirely overcomes this objection, and can 'be readily secured about the joint and held in place as shown while serving to bind the furnace and assist in securing the top plate to the side radiator plate. I believe myself to be the first to employ a cement ring for this purpose.
I do not confine myself in this invention-to the application of the ring to any particular joints in the furnace, or to a cylindrical furnace, since it could be equally well applied to other shapes of furnace.
Having described my invention, what I claim as new, and desire to secure by Letters Patent, is-- In ahot air furnace the combination with a cast iron top plate and steel radiator side plate of a cement ring inclosing thejoint be-' tween said plates, and means for securing the cement ring inposition and for binding the plates together, consisting in sectional con: cave-plates clamped over said furnace joint and cement ring, substantially as set forth.
