ANDERSON, OF GROSSE ILE, MIGHIGAN, ASSIGNOR TO AMERICAN BLOWER CORPORATION, OF DETROIT, MICHIGAN, A CORPORATION OF DELAWARE UN IT HEATER AND VENTILATOB Application filed June 16,
tories and other large commercial buildings.
It is my object to provide a relatively shallow, tall casing, the walls of which are spaced above the floor to withdraw cold air fromthe floor, elevate the air in a broad narrow stream, heat it or otherwise condition it and discharge it at a relatively high point in the room where it cannot cause drafts and where it will be distributed in a broad narrow stream.
It is particularly mg} object to move the air in the same plane. eretofore, it has been necessary to take the air in through the side of a fan in its eye and then change its direction at right angles and discharge it. This results in large and cumbersome structures which are not adapted for unit heating and ventilating of this character. There is a material reduction in power consumption and a vast increase in efliciency of heating by being able to move the air in a. single blast in a narrow stream and distribute it in a narrow stream over a broad area.
It will be understood that this heater can be used either with or without a recirculating box; the primary object ,of my invention is the application of the heater section to a line flow fan.
Referring to the drawings Figure 1 is a side elevation of the casing containing a line flow fan and heater;
Figure 2 is a side elevation thereof; Figure 3 is a top plan view; Figure 4 is a section on the line 44. of Figure 1;

Figure 11 is a section on the line 11-11 of Figure 8;

Figure 15 is a section on the line 1515 of Figure 14;
Figure 16 is an end elevation of a form with a right-angle flow with the radiator and the outlet;
Figure 17 is a section on the line 17-17 of Figure 16.
Referring to the drawings in detail, I provide a frame work consisting of angle iron corner pieces 1 having transverse floor mem-v bers 2 joining the frame members in pairs. Spaced above the floor, leaving air inlet openings 3, I mount on these corner pieces 1, side walls 4 and front and rear walls 5. These walls terminate about midway the structure and are provided at their upper ends with braces 16 so that an air outlet'opening 17 is Figure .13 is a section showing another.
provided. In the form shown in Figures 1 t0 7, the discharge is directly upwardly, while,' in the remaining forms, the discharge is lateral. In the form shown in Figures 8 to 13 one of the walls 8 is formed into an ar- I cuate hood 18 to effect this lateral discharge. The motor is supported upon a bracket 19 of any suitable character.
It will be noted that the line flow fan extends completely across the outlet opening i and across the relatively long and narrow radiator. The diameter of the fan is a fraction of its length.
I preferably provide an air inlet guiding;
of the casing for supporting the fan and motor shaft 14.
The purpose of the guiding plate is to direct the air into that half of the fan where the blades are moving from the air inlet to the air outlet and to cooperate with the screen plate 21 in screening the blades as they re turn from the air outlet towards the air inlet. I prefer that form shown in Figures 5 and 7 and Figures 12 and 13 where there is an appreciable air flow space 24: adjacent those blades that are moved from the air inlet to the air outlet so that the air has an unimpeded passageway through which it is impelled and induced to flow by these blades that are traveling in the direction of the air while these blades that are traveling in the reverse direction are screened from coming in contact with the air by the closely adjacent arcuate screen 21.
The radiator, or any other equivalent mechanism, such as a cooling coil or air conditioning mechanism is provided with circulation pipes 25 and 26.
It will be understood that I desire to comprehend within my'invention such modifica- 1 of the fanffrom the tions as may be necessary to adapt it to varying conditions and uses.
Having thus fully described my invention, what I claim. as new and desire to secure by Letters Patent, is
1. In combination, a casing having a lower air inlet and an upper air outlet, a line flow fan mounted therein, the axis of which is ofiset to one side of said casing providing a fan free space to one side of said fan but not on the other side.
2. In combination, a casing havin a bottom inlet and a top outlet, a line fIow fan therein providing free space to one side of the fan, and means to screen the blades of the fan from the fiowing'air passing throu h the casing as those blades return from t e air outlet position to the air inlet position.
3. In combination, a casing forming an air passagewa and having a bottom inlet and a top out et, a line flow fan therein, and means in said passagewa to screen the blades owing air passing through the casing as those blades return from the air outlet position to the air inlet position, said screen comprising a guide plate, an arcuate screen and an outlet plate.
4. In combination, a vertically disposed broad shallow casing supported above a floor having an open bottom and an open top, a
radiator therein, a line flow fan adjacent thereto and extending across a broad side of the casing adapted to move air over the radiator and discharge it from said casing.
5. In combination, a vertically disposed broad shallow casing supported above a floor having an open bottom and an 0 en top, a radiator therein, a line flow fan a jacent thereto and extending across a broad side of the casing adaptedto move air over the radiator and discharge it fromsaid casing,
said fan being so arranged that the air enters one side and leaves the other side in the same plane.
6. In combination, a casing supported above a floor having an open bottom and an open top, a radiator therein, a line flow fan having horizontal blades adjacent thereto adapted to move air over the radiator and discharge it from said casing, the blades of said fan being so arranged that the air enters one side of the fan and leaves the other side in the same plane, and means to provide a fan free space to one side of the fan adjacent the blades of the fan which are moved from the air inlet to the air outlet position.
7. In combination, a shallow broad casing, means of supporting it above the floor, said casing having an open bottom and top, a line flow fan coextensive with the width of the casing having its major axis parallel thereto and adapted to take air in through one side of the fan through the bottom of the casing and dischargeit through the other side of the fan out of the top of the casipg Without changing the plane of movement'of theair as it is discharged in a broad narrow stream, and means of su portingsaid fan with its axis offset from tlie transverse center line of the casing.
