ALBERT A. KNISELEY, OF DETROIT, MICHIGAN.

GAS HEATER.

Application filed April 17, 1924. Serial No. 707,134.

To all whom it may concern:

Be it known that I, ALBERT A. Kivrsnnnv,

a citizen of the United States. and residing at Detroit, in the county of l/Vayne and State of Michigan, have invented a new and Improved Gas Heater, of which the following is a specification.

This invention relates to gas heaters especially adapted to be used for heating garage structures and it consists in the'novel features hereinafter described and claimed.

An object of the invention is to provide, a heater which uses gas as a fuel with means for leading a current of air from the exterior to the interior of agarage structure, the parts and features being so arranged that the said current of air may absorb the heat units as it passes through the heater and consequently is discharged into the garage structure in a-heated condition.

7 With the above objects in view the heater comprises a housing which passes through the wall of the garage structure, a door being hingedly mounted in the housing at its 25 upper edge and at a point between the ends of the housing. A gas burner is located in the inner portion of'thehousing and an air conduit is located above the burner and is,

adapted to receive a current of air under the lower edge of the door and from the outer portion of the housing and deliver the same through the top of the housing into the garage structure.

These objects and the several novel features of the invention are hereinaftermore fully described and claimed and the preferred form of construction by whichthese objects are attained is shown in the accompanying drawings in which Fig. l is a fragmentary section view 0 a garage wall with the heater applied and shown in section.

F'g. 2 is a plan view of the heater.

Fig. 3 is an end elevation of the heater.

Fig. 4 is a fragmentary sectional view of the roof of the garage showing a fume pipe passing therethrough.

As illustrated in the accompanying drawings the wall of agarage structure is indicated at 1 and the roofthereof at 2. A housing fi'pas'ses transversely through the burner 6 may be maintained in a lighted condition all of the time and may light the gas at the burner 4 when the valve in the pipe 5 is opened and permits the gas to flow to the burner 4 in the usual manner. A

fume pipe 7 connects with a cone shaped hood 16 hereinafter referred to. The said pipe 7 passes through the roof 2 as best shown in Fig. 4 of the drawings. A ventilating sleeve 8 is mo'unted upon the upper portion of the pipe 7 and also passes through the roof 2. A flashing 9 is connected with the ventilating sleeve 8 and the roof 2 in the usual manner and as shown in Fig. 4 of the drawings.

A door 10 is hingedly mounted at its upper edge in the upper intermediate portion of the housing 3 and is disposed transversely thereof. The door 10 is flanged outwardly atthe lower edge at 12 as shown and a partition 11 is provided across the housing 3 having raised beads 30 and 31 which space the door 10 from the panel 11, the door resting on these beads 30 and 31 and providing an air space between the door 10 andpanel 11 to prevent the door from becoming heated. The panel 11 is provided atthe lower edge with an inwardly disposed flange 13 and a handle 14 is secured to the lower portion of the door 10.

An air conduit 1518 located in the inner portion of the housing 3 and is disposed vertically above the burners 4 and 6. The inlet end of the conduit 15 is disposed below the lower edges of the flanges 12 and 13-01? the door 10 and panel 11 and the delivery end of the conduit 15 passes through the side of a cone shaped hood 16 mounted upon the top of the housing 3 and which is located vertically above the said burners. The pipe 7 is connected with the hood 16 as best shown in Fig. 1 of the drawings. A screen 17 (see Fig. 2) is disposed across the outlet end of the conduit and prevents rags or other material from being thrown or deposited in the conduit. The cone shaped plate 16 prevents the setting of oil cans or similar receptacles upon the top of the housing 3 above the burners a and 6. The flange 13 ot the innerpanel 11. is recessed at 18 to receive the lower portion oi the conduit 15 as shown in Figl'fll of the drawings. The conduit 15, as will be understood from Fig. 1', is niade up of a series of pipe sections 19, 19", 19, 19 and chambers 20. The lowern'iost conduit 19' is in the form or an elbow having an inlet end 19 and opening at its upper end to the lower chamber 20. The next pipe section 19" connects with the first chamber and discharges to the second chamber. The third section l9 connects at one end with the second chamber and the other end with the third chamber and the last pipe section 19 discharges through the hood 16 and is' provided with a screened outlet opening 17 as heretofore stated. The pipe sections are ar ranged in staggered relation as sl'iown'-that is, the end of one pipe section connects with one side of the chamber and the next pipe section connects with the opposite side of the same. Preferably the chambers are successivelv of less volunietric content successively decreasing in diameter. Baflie' plates 21 are mounted upen the inner surface of the inner panel 11 and are adapted to bear against the edges of the chambers where by the fumes and heated gases from the burners 4 and 6 are directed away from the door 10 and toward the intermediate portions of the disks 20. I

It is apparent that when the burners 4 and are lighted the heated gases andftumes 1 come in contact with the exterior surfaces of the pipes 19 and chambers 20' and the heat units are absorbed by the said pipes and chambers and transmitted to the current of air which is passing therethrou'gh.

The various parts of the conduit 15 are refer-ably welded tegether to prevent a leakage of the gases into the conduit.

From the. foregoing description it be comes evident that the device is very sir'nple' and efiicient in operation, will not easily get outer order, provides a safe means for heating a or siniilai? s iuc ture and 1'3 1 vit.les a device which accein )lisl1es the objects described.

Having thus-fully described intention, its'utility and mode of operation, what l claim and desire to secure by Letters Patent of the United States is" V 1:.
