OIL-BURNING- FURNACE.

Specification of Letters Patent.

' Patented J an. 13,1914.

Application filed April 21, 1913. Serial No. 762,530.

To all whom it may concern Be it known that I, JosnrH J. HASKIN, 'a citizen of the United States, residing at Stockton, in the county of San Joaquin and State of California, have invented new and useful Improvements in Oil-Burning Furnaces, of which the following is a specification.

My invention relates to improvements in furnaces which are especially designed for the burning of oil.

It consists in a novel construction of the furnace floor, the arch at the rear, and air draft openings, and in details of construction which will be more fully explained by reference to the accompanying drawings, in which Figure 1 is a side elevation and .vertical section of parts ofthe furnace. Fig. 2 is an end view and partial vertical section. Fig. 3 is a view of the arch at the rear of the furnace.

The object of my invention is to provide a more eflicient and permanent construction of brick lined furnaces, when used espec ally in connection with locomotive or similar furnaces which' are subjected to jars and other strains which are liable to loosen the bricks and cause them to fall, and which the present construction is designed to overcome, and to greatly extend the life and efficiency of the furnace.

Furnaces have been made with flat floors and also with arches built in the usual manner, but in such cases they soon become disintegrated. The sand which is used in cleanflues works its way into the cracks and joints of the furnace floor, and soon causes the floor to rise and interfere with the proper discharge of the fuelblast. Where the arch between the fire box and flue sheet is made in separate sections, the jar of the engine soon loosens these sections and they work out and the arch will drop. For the purposes of this description the flue sheet end will be called the front and the opposite end the rear.

In my invention the closed bottom A of the firebox has its upper side edges connected with the inner side walls of the water jacket below the mud ring, as shown at 2,

Fig. 2; thence these walls converge downwardly and at the lower edges they extend inwardly at right angles, thus forming inclined offsets and supports 2 forthe lining bricks which rest upon and cover the ledge thus formed, lying against the convergent sides and forming a continuation of the vertical. side walls 6 of the fire box. From the inner edges of the offsets 2 the bottom forms a flat, segmental, inverted arch which is lined with bricks 5, meeting and forming a continuation of the side linings; the arch and'the inc-lined sides insuring the retention of the lining in position and enabling the placing of this lining by unskilled labor.

The arch 4 of the furnace is composed of a plurality of segments, each of which forms a complete curve from side to side, and these segments are made with interlocking tongues and grooves on their meeting edges, as shown at 7. In the present case the grooves are made V-shaped and the tongues of the .same shape, following the curvature of the arch, and when the two are placed together they support each other and prevent any tendency to loosen or come out.

In order to make it possible to do this work with unskilled labor, the sides of the arch are offset, as shown at 8, and have the lower surfaces at the angles so made that they will rest flat upon the. lining bricks which are laid up straight, as previously described. The arch is shown as divergent and having an upward pitch from its junction with the front wall toward the interior of the furnace over which it overhangs. By this construction the parts of the side, lining and arch are effectively related and the life of the furnace is very greatly increased.

The burner 9 may be of any suit-able or desired description, such, for instance, as shown in my prior Patent No. 1,029,927, dated .June 18, 1912. This burner opens into the fire-box below the mud ring 3. Heated air is introduced into the rear part of the burner to commingle with and discharge the oil therefrom into the furnace.

Above the burner, between it and the mud ring, is a wide draft opening formed by means of a plate 5 which extends across the whole width of the opening. This forms an air inlet which allows air to pass in above the burner. The hot air, as before stated, is supplied from below and is enough to insure the proper ignition of the oil, while the supply which enters the fire box from chamber 10 serves to complete the combustion within the furnace as the gases pass to the rear and return beneath the arch 4.

Having thus described my invention, what I claim and desire to secure ent is- 1. A furnace fire box having substantially vertical and lined side walls and a mud ring, a bottom composed of inclined sides converging from the mud ring at the bottom of the side walls and having inwardly turned, ofiset supports at right angles, linings for said inclined sides, and a fiat inverted arch intermediate of the offsets, and a lining of abutting bricks fitting said arch and forming a continuation of the inclined side linings.

2. In a furnace fire with the water jacket, a bottom comprising side members attached at their upper sides to the water jacket, and an inverted arch by Letters Patbox, in combination vbricks on the projections and forming continuations of the last named bricks.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
