OF BUTTE, MONTANA WALL SHIELD, SHELF, AND VENTILATOR -App1ication filed. May 31, 1932. Serial No. 614,511.

The invention aims to provide a new and improved combination article adapted primarily to be used over the rear portion of a hot water or steam radiator, for the purposes of preventing uprush of dusty air along the wall behind the radiator, forming a convenient shelf, and discharging fresh air into the hot air rising from the radiator, the fresh air serving effectively for ventilation, but

being effectively heated so that it will pro duce no drafts.

With the foregoing in view, the invention resides in the novel subject matter hereinafter described and claimed, description being accomplished by reference to the accom' panying drawing.

Fig. 1 is a front elevation showing the article mounted upon a wall over the rear portion of a radiator.

Fig. 2 is an end elevation, a portion of the wall and floor being in section.

Fig. 3 is a sectional perspective view through a portion of the combined wall shield, shelf and ventilator.

Fig. 1 is a diagrammatic view illustrating the manner in which fresh air may be supplied to the device.

The invention consists primarily of a horizontally elongated casing 5 preferably formed from sheet metal and adapted to be mounted over the rear portion of a steam or hot water radiator 6, said casing being provided with a fresh air supply pipe 7 and with a plurality of air discharge perforations 8. The pipe 7 may well connect with an air line 9 leading from a fan or blower 10 which receives fresh air through a screened inlet 11. Preferably, a valve 12 is provided in the pipe 7 to control the amount of fresh air entering and discharging from the caslhe casing 5 is preferably of substantially right angle triangle form in transverse section, and it may be provided with any appropriate means for mounting it against a wall 13 behind the radiator 6. In the present showing, the ends of the casing 5 are provided with vertical attaching flanges 14 secured by screws or other fasteners 15 to the wall,

said flanges being in the same plane with the vertical back wall 16 of the casing, so that the extreme lower corner 17 of the casing 5 will lie against the wall 13 to forwardly direct all ascending hot air, instead of allowing the latter to flow directly upward along the wall, with danger of carrying dust and the like and discoloring said wall. The front wall 18 of the casing 5 inclines from the edge 17 and is joined to the front edge of the top wall 19 of said casing. The ex-. treme upper longitudinal portion of the front wall 18 denoted at 20, preferably possesses considerably less inclination than the remainder of said front wall, and in this portion 20, the air discharge perforations 8 are formed. It is thus insured that the discharged air shall be directed downwardly to thoroughly mix with and become heated by the air rising from the radiator 6.

The device may be quickly and easily mounted over any radiator and when installed, it serves as a wall guard, to prevent the ascending heat from traveling directly along the wall 13, serves further as means for discharging ventilating air into the ascending hot air, and serves still further as" a convenient shelf.

WVhile the details disclosed may well be followed, variations may be made within the scope of the invention as claimed.

1 claim 1. A combined wall guard and ventilator for use over the rear portion of a radiator, comprising a horizontally elongated casing provided with an air inlet and having a forwardly inclined front wall for directing ascending air forwardly, the upper portion of said wall having air discharge perforations, and means for mounting said casing against a wall behind the radiator.

2. A combined wall guard, shelf and ventilator for use over the rear portion of a radiator, comprising a horizontally elongated casing, said casing having a vertical back wall to lie against a wall behind the radiator, a horizontal top wall, and an inclined front wall which inclines from the lower edge of said back wall to the front edge of said top wall, the upper portion of said front wall having air discharge perforations, means for fixedly mounting said casing, and means for supplying air thereto.

structure as specified in claim 2; said perforated upper portion of said front wall being disposed at a considerably less inclination than the remainder of said front wall to directthe discharging air downwardly.

In testimony whereof I aflix my signature.

TIMOTHY J. SULLIVAN.
