RADIANT-HEATER ATTACHMENT.

Application filed August 1, 1927. Serial No. 209,832.

My invention relates. to radiant electric or gas heaters for domestic use, and it has for a purpose the provision of an attachment for heaters of this character by which the radiant heat generated therein is converted into convected heat by causing air to be circulated by thermal action through the interior and against the exterior of the attachment, thus heating the air more rapidly and thereby increasing the heating cfiic-iency of the conventional radiant heater.

I will describe only one form of radiant heater attachment embodying my invention and will then point out the novel features in claims.

In the accompanying drawing:

Fig. 1 is a view showing in side elevation one form of attachment embodying my invention in applied position to an electric radiant heater;

Fig. 2 is aview showing the heater and attachment in top plan; and

Fig. 8 is a vertical sectional view taken on the line 33 of Fig. 1.

In carrying out my invention, the attachment may be of any suitable design to render it applicable to a gas or radiant heater of any particular form so long as it embodies the structural characteristics necessary to accomplish the conversion of radiant heat into convected heat. a

My invcntion in its present embodiment is in the form of a cylindrical body 15 of metal or other suitable material and of such diameter as to render it applicable to the concave side of a reflector of an electrical radiant heater. One end of the body 15 is closed by a wall 16, the opposite end of the body being open and detachably secured to the reflector R of the heater by means of clips 17 arranged at circumferentially spaced intervals on the attachment body so as to engage the periphery of the reflector and. thereby secure the attachment to the reflector in such position that its axis is centered with respect to the axis of the reflector.

As clearly illustrated in Fig. 3, the inner side of the wall 16 is provided with a suitable baflie member 18 which. in the present Instance, is cylindrical in form and positioned concentrically of the body 15 so as to provide an interposing medium between a pair of

openings

19 and 20 formed in the body 15 preferably at diametrically opposed points. In the present instance the lower opening 19 is disposed directly below the teriorly and exteriorly. By reason of the

openings

19 and 20 the thermal action of the radiant heat causes atmospheric air to be circulated through the interior and against the exterior of the attachment whereby a more rapid heating of the air is effected than is possible by direct radiation. Thus, the heating efficiency of the heater is greatly increased.

By a consideration of Fig. 3 it will be evident that the battle 18 distributes the incoming cool air uniformly over the entire interior surface of the attachment thereby effect ing a maximum conversion of the radiant heat into convected heat, the heated air escaping through the opening 20 to atmosphere. In this manner a constant circulation of cool air interiorly of the attachment is produced, and conversely av consistent discharge of heated air from the attachment.

My invention renders more practicable the use of a radiant heater in a small room, such as a bathroom, where concentrated reflected heat is impractical and dangerous. In actual use my attachment provides a heating surface of relatively low temperature due to the constantly circulating convection currents, the temperature being similar to that of a steam radiator and thereby reducing fire risk and preventing burning or overheating of the air which results by direct contact with highly heated surfaces, and which is objectionable from a sanitary and health standpoint.

Although I have herein shown and de scribed only one form of radiant heater attachment embodying my invention, it is to be understood that various changes and modifications may be made herein without departing from the spirit of. the invention and the spirit and scope of the appended claims.

I claim:

1. An attachment for radiant heaters comprising a circular body closed at one end and open at the other, diametrically opposed openings in the body adjacent the closed end thereof, and a circular battle in the body and concentrically spaced therefrom, said baflie being disposed between said openings.

2. The combination With a radiant'heater employing a concavo-convex reflector, of an attachment therefor consisting of a cylindrical body member open at its rear portion and closed at its front portion, the open rear portion having a diameter agreeing approximately with that of the reflector of the heater,

a cylindrical baflie extending from the closed frontportion of the body member and terminating in spaced relation to the said open at a point beneath the battle and an outlet 2 opening above the baiiie for the heated air, and means securing the body member to the reflector of the heater so as to closely relate the said open rear portion with the concave of the reflector.
