fie SUPPLEMENTAL HEATING ATTACHMENT FOR FURNACES.

To all whom it may concern:

Be it known that I, JOHN A. ABRAMS, a citizen of the United States, residing at Wadsworth, in the county of Medina and State of Ohio, have invented certain new and useful Improvements in Supplemental Heating Attachments for Furnaces; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in supplemental heating attachments for furnaces.

One object of the invention is to provide a gas heated attachment of this character whereby a portion of the air passing through the furnace is super-heated to an intense degree and then turned back and mixed with the main volume of air passing through the furnace thereby greatly increasing the heating capacity of the latter.

Another object is to provide a supplemental heating attachment of this character which is especially adapted for burning natural gas and which is provided with a water heating coil.

With these and other objects in view, the invention consists of certain novel features of construction, combination and arrange ment of parts as will be more fully described and particularly pointed out in the appended claims.

In the accompanying drawings: Figure 1 is a plan view showing the application of the invention; Fig. 2 is a vertical sectional View of the same on the line 22 of Fig. 1; Fig. 3 is a similar view at right angles to Fig. 2 and on the line 3-3 of Fig. 1.

In the embodiment of the invention I provide a box or casing 1 which is preferably of fiat rectangular shape and constructed in upper and lower sections 2 and 3. The upper edge of the lower section 3 is oifset to form a seat 4 and an attaching flange 5 for the lower edge of the upper section, said edge of the upper section being secured to the flange 5 by screws or other suitable fastening devices. The outer corners of the upper section 2 are preferably inclined as shown. The box is secured to one side of the furnace by fastening plates 6 and is connected with the air space of the furnace by upper and lower air conducting pipes 7 and Specification of Letters Patent.

Patented Nov. 14, 1911. Serial No. 607,692.

8 whereby a portion of the air from said space is conducted through the box.

Arranged in the box is a gas radiator 9 comprising a flat box of such size as to provide a space all around between the same and the inner walls of the casing 1. The radiator is supported in the casing by a horizontally disposed supporting rod 10 which extends through the radiator and casing and has its projecting ends threaded to receive fastening nuts 11. On the rod between the ends of the radiator and the adjacent ends of the casing. are arranged spacing sleeves 12, whereby the radiator is held in proper position in the casing. The lower end of the radiator is open and is provided'with a curved baffle plate 13 which forms a reduced space through which air may enter the radiator to provide the mess sary ventilation for the gasburner 1 1 which is in the form of a perforated tube and extends horizontally through the lower portion of the radiator and has its ends projecting through the ends of the same and through the ends of the casing. On one end of the burner tube is arranged a cap 15 and on the opposite end is arranged an air mixer 16 and a cut off valve 17. On the tube 14 between the outer ends of the radiator and the adjacent inner surface of the end of the casing are arranged spacing sleeves 18 whereby the lower portion of the radiator is held in position. In one end of the radiator immediately above the burner tube is arranged an opening 19 which alines with a similar opening 20 formed in the adjacent end of the box whereby the burner may be lighted. In the upper end of the radiator is arranged a vent pipe 21 which extends through the top of the casing and may connect with the chimney or flue. If desired the attachment may be provided with a water back which is here shown and is preferably in the form of a coil or loop of pipe 22 arranged transversely through the radiator and casing as shown.

By means of a heating attachment such as herein shown and described a portion of the air from the air space of the furnace is conducted through the casing 1 and superheated to an intense degree and then returned to the air space of the furnace thus mingling with the air therein and increasing the heat thereof whereby the capacity of the furnace is greatly increased.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention, as defined in the appended claims.

Having thus described my invention what I claim is 1. A supplemental heating attachment for furnaces comprising a casing, means to secure the same to the furnace, upper and lower air conducting pipes to connect said casing to the air space of the furnace, a gas heated radiator arranged in said casing and having an open bottom, said radiator being spaced from the walls of the casing, a supporting rod arranged through the upper portion of the radiator and through the casing, spacing sleeves on the ends of said rod whereby the radiator is held in position, a perforated burner tube arranged through the lower portion of the radiator and through the side of the casing, spacing sleeves on said tube, an air mixer on one end of the tube, a baffle plate arranged in the open lower end of the radiator, a vent pipe connected to the upper end thereof and a water heating coil arranged through the radiator and casing.

2. A supplemental heating attachment for furnaces comprising a casing, means to secure the same to the exterior of a furnace, upper and lower air-conducting pipes to connect said casing with the air space of the furnace, a radiator arranged in said casing and having an open bottom, said radiator being spaced from the walls of the casing, a supporting rod arranged through the upper portion of the radiator and through the casing, spacing sleeves on the ends of said rod whereby the radiator is held in position, a burner tube arranged throughthe lower portion of the radiator and through the sides of the casing, spacing sleeves on said tube, a baifie plate arranged in the lower open end of the radiator and a vent for the radiator.

3. A supplemental heating attachment for furnaces, comprising a casing to be arranged on the exterior of the furnace, upper and lower air-conducting pipes to connect said casing to the air space of the furnace, a radiator supported within the casing and spaced therefrom, the bottom of said radiator being open and disposed slightly above the lower air-conducting pipe, a transversely curved baffle plate arranged at the open bottom of the radiator and supported on the inner wall of the radiator whereby the air passing into the radiator through said lower air-conducting pipe will be deflected by said curved deflector away from the open bottom of the radiator, a burner in said radiator and a vent for said radiator.

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