Patented May 3, 1932 UNITED STATES PATENT OFFICE WILLIAM; J. BACON, OF MEMPHIS, TENNESSEE, .ASSIGNOR T MYRTLE M. BACON, 0F MEMPHIS, TENNESSEE RADIATOR COVER Application led J'une 4, 1928. Serial No. 282,852.

My said invention relates to a radiator cover, and it is an object of the same to provide a radiator cover which shall conform as nearly as possible to the structure of a {ire-place in which there is a forced draft.

This device may be set over any form of radiator for water or steam or a modied form may be arranged in front of a radiator set into a recess in a wall. Within the scope of i@ my invention it may also be used over other sources of heat which are broadly the equivalents of a radiator, specific terms being used in the claims for purposes of description rather than limitation. It has been found from actual experience that the best results are obtained with a casing having a mesh wire strainer covering an opening in the lower part of the front wall of the casing and another mesh wire strainer covering an opening in the upper part of said wall, the entire casing being preferably insulated, except at the openings, to prevent radiation which tends to set up a secondary circulation of air. It will be understood that if the air adjacent the outer walls of the casing is heated by radiation it will create a circulation such as will carry up dust from the floor without passing through the casing itself whereby the dust can be removed from the air by the 130 screens and also by reason of the changes of direction in the travel of the air through the casing.

It is an object of my invention to provide a casing in which the air shall change direct. approximately horizontally, then rises and then passes out approximately horizontally.

In this movement the air current strikes 40 against solid surfaces that help to cause particles of dirt in the air to be separated out of the same. Even in passing through the air screens or filters the current is not at rightangles to the filter and the impingement of 45 particles of dirt against the screen at an angle ion preferably three times; i. e., it passes in to the same helps to separate the dirt therefrom.

Another object of the invention is to prevent the formation ot a pocket of air at the top ofthe radiator and for this purpose I provide an inclined plate rising from the rear of the casing toward the front to direct the current through the upper opening whether or not the same is provided with a screen.

Another object is to provide a. forced draft. For this purpose I provide a smaller opening at the top of the casing than that at the bottom, which accelerates the passage of air out from the radiator, creating a draft along the floor and throwing the heated air out into the room away from the wall. By this means the room is heated more quickly than would otherwise be the case. For this purpose also I provide horizontal inwardly 5 curved surfaces at the front and back of the casing which create a throat in the radiator cover for accelerating the movement of air through the radiator. It has been found by experiment that if the outlet is smaller than the inlet the air will pass out with a greater speed and it is intended to provide a device which shall speed up the circulation of air in the middle of the room rather than merely along the walls and the ceiling.

Referring to v the drawings, which are made a part of this application and in which similar reference characters indicate similar parts:

Fig. 2, a transverse, vertical section of the same, and

Fig. 3, a perspective of a modified form.

In the drawings reference numeral 10 indicates a radiator of any conventional or cle--r` sired type with which my improved radiator casing may be used. The casing has a rear wall 11 with a longitudinal inward curved portion l2, a flat top 13, ends 14 and 15 and a `ISIS front wall 16 having a horizontal curved portion 17. The front, rear and side walls are insulated as indicated at 18 and an inclined plate '19 above .they top Vof the radiator or other heating device. is also insulated, this plate being for the purpose of throwing the air current forward and preventing the formation Y cated in Fig. 1 at 23.
