PORTABLE HEATER.
' Specification of Letters Patent.
' PatentedNov. 16, 1915.
Application filedJune 19, 1912. Serial No. 704,546.
'1 '0 all whom it may concern Be it known that we, EDWARD B. OnLKnR and FREEMAN C. LUDLoW, citizens of the lnited States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Portable Heaters, of which the following is a specification. I i 7 Our invention relates to improvements in portable heaters. I
One of its objects is to provide a .heater which may be moved from place toplace without liability of injuring the floor, rugs or articles offurniture.
Another object is to provide a heater in which the burners while well supplied with air are protected from drafts and excessive air currents.
Another object is to provide a heater in which the heated air is evenly disseminated into the room, and uniform air currents to and from the heater are insured.
Another object is'to provide for a supply of fuel thoroughly mixed with air and supplied to the burners in regular quantity and at uniform pressure. 1
Our invention further comprises certain details of form, combination and arrangement, all of which will be fully set. forth in connection with the accompanying drawings in which:
s Figure 1 is an end View; of our improved heater. Fig. 2 is a vertical section through the same on line at m of Fig. 3. Fig. 3 is a horizontal sectionjthrough the heater on line zzofFigQ, I
The accompanying drawings illustrate the preferred embodiment of our invention, which- A A represent the end plates of the heater. 7 j j B represents a cylindrical drum supported by the end plates and open to the air of the room at both ends through said end plates. D represents a sheet metal plate encircling the cylinder B and open at the bottom, said plate D being supportedinposition by and between said end plates.
Gaseous fuel is supplied through the tube 2 controlled by the cock 3, and is'mixed with external air in the'requisite proportion by means of an adjustable mixer 4. The mixed air and gas passes along the tube 5 supported by the end plates A A, in which tubetheair and gas are more thoroughly mixed and are heated by reason of the close proximity of the burner tubes.
Various causes such as uneven gas pressure, irregularity in the heating of the air and gas in tube 5 cause the fuel issuing from tube 5 to fiuctuate'to a certain extent in quantity or pressure, and
we therefore provide an equalizing or regu- V lating receptacle 6 to insure a constant supply and'practically uniform pressure of gas at the, burner jets, said receptacle being interposed between the exit end of tube 5 and the inlet ends of the burner tubes 7 and 8. This chamber 6 is preferably formed by being cast integral with the end plate A, and provided with inwardly projecting bosses 9,10 and 11, to receive and support the ends of the tubes 5, 7 and 8. The plate A is provided with blind or closed bosses' 12 to receive and support the opposite ends of the tubes 7" and 8, and a perforated boss 14 for the passage of the tube 5.
The burner jets or perforations in the respective tubes 7 and 8 are arranged as indicated in Figs. 2 and 3, so as to cause a circulation of heated air and products of combustion around the drum B and between said drum and the plate D, thereby heat ing said drum B andplate D and causing the air I in contact with the inner face .of the drum and the outer face of plate Dto become heated and to circulate by the laws of convection, giving place to fresh cooler air from beneath the heater.
In order, to control the circulation of air to and from the heater and protect the floor and articles of furniture frombeing excessively heated or injured, and to protect the burners from excessive drafts or air currents we provide an imperforate plate E beneath the burners which receives heat by radiation downwardly from the burners, .and protects the floor or rugs from excessive heat or injury. The heat taken up by the plate E is given off above and below to air in the side plates 17 and 18, or rises and takes up heat from the exterio of plates D f either passes out directly through openings and then passes out through openings in the a side plates 17", and 18. A perforated plate or cap H is preferably detachably seated above the upper portion of the plateD and air enters through the lower perforations in the sides of saidcap, becomes heated by contact with the exterior of plate D and escapes through. perforations in-the top and upper portion of the sides of said cap. If desired, the'cap H may be removed'or omitted. Also if desired, one of theside plates 17 and 18 may be imperforate and the other perforated, thus directing the heated air currents chiefly to one'side of the heater. I
' Ourimprovedheater thus protects itself from drafts and air currents,-and may be "freely and safely moved about w thout danger'of -1n ury from excessive heat, and whlle in operation, furnishes a copious supply of air heated to'moderate degree.
The device herein illustrated and de-,
' scribedis capable of considerable modifica- :tion without departing from the principle of our invention. c
Having described ourmvention what we claim is lfAportable heater comprising substantially vertical endplates each having upper and lower air inlet ports through their lower portions, a substantially cylindrical heating member supported upon and between the upper portions of said end plates above said air inlet ports and providedwith a central air. heating drum open 'at'both ends, an
' posite sides of said heatingmember, and inimperfor'ate substantially horizontal 7 deflector plate below said heating member and between the upper and lower 'air inlet ports and between said end plates, and substantially vertical side plates'extending from one of said end plates to the other'on' opclosing the space below said heating member 'to the floor, one of said side plates being perforated,'and said several plates'being so arranged as to cause the inflowing air cur-- rents through said inlet ports'to reach and 1 become heated from the exterior of saidheating member and'to thence escape through the-perforations of said side plate, a plurality of burner tubes extending from one end plate to the other below said heating imember, a tube supplying mixed air and gaseous fuel in position to be preheated from said burner tubes, and an equalizing receptacle carried by one of said end'plates,
and connecting said supply tube and said burner tubes, into which receptacle preheated air and gaseous fuel is discharged from said supply tubeand thence distributed to said burner tubes.
fiopies'of this patent may be obtained'for 2. A portable heater comprising substantially Vertical end plateshaving upper and lower air inlet ports through'their lower portions, a horizontal'cylindrical heating member supported at its ends upon and be tween'the upper portions of said end plates above the air inlet ports and provided with a central air heating drum open at both ends, an imperforate substantially horizontal deflector plate located intermediateof the upper and lower air inlet ports between said end plates, and substantially vertical. side plates extending from one of said end plates to the other on opposite sides of saidheat .ing member and inclosing the space below fsaid'heating member to the floor,'one of said side plates being perforated, and said several plates being so arranged'as to cause the inflowing air currents to enter through said respective air inlet ports to reach" and become heated from said heating member and said deflector plate, and to" thence escape through the perforations of said side plate.
3. A portable heater comprising substair' 'tially vertical end plates having upper and lower air inlet ports through theirlower portions, a horizontally cylindrical heating member supported at its ends upon and between the upper portions of said end plates above the air inlet ports-and provided with a central air heating drum open at'both ends,
an imperforate substantially horizontal deflector plate located below said heating member and between said upper and lower air inlet ports and between said" end plates, substantially vertical perforated side plates eX- tending from one of said end plates to the other on opposite sides of sald heating member and inclosin nthe space below said heating member to the floor, and a perforated cap member seating upon the upper edges of saidtend plates and side plates and inclosing the upper portion of sald-heating member with an intervening air space, said several members be ng so arranged as} to causeftl'ie inflowing air currents'to enter through said air inlet ports in said [s de plates and through the lower perforations in said cap member to reach and become heated from the exterior of said heating member, and to thence escape through the perforations of said side plate and upper perforations of said cap member.
' Intestimon-y whereof we have affixed our five cents each, by addressing" the Gommissioner'oflPatents, Washingt0n,D.C'. i
