THOMAS BROOKS, OF PETERBOROUGH, CANADA.
HOT-WATER FURNACE.
SPECIFICATION forming part of Letters Patent No. 49 8,531, dated 1V[ay so, 1893. Application filed May 4, 1892. Serial No. 431,787. (No model.) Patented in Ganada. 3 17.116 21.1892, No. 39,171.
To all whom, it may concern:
Be it known that I, THOMAS BROOKS, of the town of Peterborough,in the'county of Peterborough, in the Province of Ontario, Canada, have invented a certain newand Improved Hot-Water Furnace, (for which I have obtained Letters Patent of the Domi-nio-n'of Gan-= proved hot water furnace, partially broken away to expose its interior construction. Fig. 2, 1s a side elevation, partially broken away.
In the drawings, A, represents the crown of the fire box and B, the grate of the same.
0, is the top of the water space which is formed between the plate 0, the crown of the fire box A, the side D, of the fire box and the side E, forming the outer wall ofthe water space. The water space formed is on both sides of the fire box and on its end remote from the fire box door F, as well as around the front of the furnace forming a complete water jacket around the fire box and, around which a smoke jacket G, is formed by the plates H, and I.
J, represents the distributing pipes and K, the returnpipes.
A smoke line L, is made through the water space and the smoke enters the smoke jacket G, if the damper M, is open and out of the smoke stack N, but by closing the damper M, it cannot escape until it has passed over the top of the water space down through the opening 0, into the side smoke jacket, thence into the smoke jacket formed at the end of the furnace and thence up through the pipe P,
one side of the furnace andthe other half toward the other opening 0, on the opposite side so as to surround the water space inclosed by the smoke jacket G. From this descriptionitfw'ill' be seenfthat th'e inside plates of the waterspace form the sides of the fire box.
Oonsequentlythe waterlin the space derives the fullest benefit from the direct heat of the fire, and owing to the formation of the smoke jacket-aroundthe water space or jacket, the heat in the smoke is utilized to its fullest extent toward heating the water in the water space. In this way I secure a very economical hot water furnace, as the water is carried in a space completely surrounded by heating surface, thereby securing the fullest benefit from the consumption of the fuel.
In order that the smoke jacket may be readily cleaned, I place at convenient points, doors R, which can be readily opened so as to permit the insertion of brushes for the purpose of cleaning out any soot which may accumulate in the smoke jacket.
F, represents the door of the fire box, T the door through which the cinders are raked oif the cinder grate U, and V, is the door of the ash pit.
With the view of still further utilizing the heat of the furnace, I sometimes make the bars forming the grate B, hollow, and connect them to the water space so that the water shall circulate through the bars and secure the direct benefit of the live coals lying on the grate. The grate may be made in an independent frame connected to the water spaces on either of the sides ofthe furnace, or the grate may be made as forming part of the furnace, being screwed into the plates forming the inner sides of the water space, as shown in the draw- A collar X, may be made around the smoke stack N, to form spaces around the smoke stack N and communicating with the Water space around the boiler.
In addition to the water grate, I sometimes add a water partition B, which extends along the center of the fire box, preferably a little above the grate so as to form a water parti tion surrounded entirely by the hot coals, thereby obtaining full benefit from the center of the fire. The partition B, may be connected to the side water jacket at one end and to the top water jacket at the other end,
as shown, or it may be otherwise connected so that the water will circulate through it.
I deem it important that this partition B be arranged in such a manner that it will be surrounded by the hot coals, as it is much betfrom rising if the partition is placed above said coals.
What I claim as my invention is,
jacket formed on top of the water space, a partition forming a longitudinal division of the said jacket and openings located on either teaser side to permit the smoke to pass down into jackets formed on each side of the furnace and communicating with a smoke jacket formed on the back ofthe furnace; substantially as and for the purpose specified.
2. In a furnace having a water space surrounding or partially surrounding it, a smoke flue leading from the fire box into a smoke jacket formedon top of the water space, and openings located on either side to permit smoke to pass down into jackets formed on each side of the water space, in combination with means, substantially as described, for
- closing the smoke flue M and driving the smoke through the side smoke jackets, as set 1. As an improved hot Water furnace, a War:
ter space formed around the fire box, a smoke flue leading from the fire box into a smokei forth.
