" Heaters, of which the `following is a specifcation.

The object of this invention is to provide a simple, inexpensive and eflicient device whereby the air rising from a heater may be disseminated and caused to more rapidly circulate through a room than is ordinarily the case so that the room will be more thoroughly heated and its temperature quickly raised to the desired degree.

The preferred embodiment of the invention is illustrated in the accompanying drawings and consists in certain novel features which will be lirst fully described and then more particularly pointed Vout in the appended claims. Y

In the drawings:

Figure 1 is a perspective View of my device in operative position upon a cylindrical stove;

. Fig. 9. is a trans-verse section;

Fig. 3 is a horizontal section on the line 3-3 of Fig. 2.

The device constituting my invention is` intended more particularly for use in connection with stoves having cylindrical bodies, as indicated at 1, but it may, of course, be applied to heating units of any form or character.v In carrying out my invention, I employ a base ring 2 which may be made of various diameters and in any particular in stance will be of the proper diameter and form to iit closely around the top end of the stove and thereby support the device in position thereon. Rising from the base ring 2 are guards or posts 3 of stout wire or similar material and supported by the upper ends of the said guards is a disk or hood 4L provided at its center with a collar or sleeve 5 to receive the lower end 6 of a motor casing "7. The extension 6 of the motor casing forms the hub or bearing for a fan shaft 8, to the lower end of which is secured a plurality of radial fan blades 9. In the preferredform of the invention, which is illustrated in the accompanying drawings, the fan is driven by an electric motor contained within the casing 7 and current to which is supplied by a conductor l0 which may run from any convenient electric lamp socket. It is to be un derstood, however, that the fan may be driven bya pulley and belt connection with a distant motor if so desired or preferred, but in any event my invention contemplates the provision of a positively driven fan located and supported over, in or upon va heater.

The use of the device is thought to be obvious from the foregoing description, taken in connection with the accompanying drawings. The heat rising from the stove will be arrested by the hood or disk 4 so that it cannot pass directly upward and accumulate in theupper portion of a room as is now generally the case. The disk or hood will ob vio-usly serve to deiiect the heated currents, but if they were merely turned aside by the hood they would simply pass up around the edge of the same so that eli'ective lateral dissipation would not be attained. By provid ing a fan, however, which is positively rotated between the hood and the top of the stove, the hea-ted currents are driven laterally from the stove and will be caused to iiow horizontally or obliquely to an appreciable distance in all directions, the result being that the temperature in the room is more quickly raised to the desired degree and is made more uniform than has heretofore been possible. The fan is rotated in the direction indicated by the arrow a in Fig. 2 so that when the blade is set at an angle the lower face of the blade will meet the heated currents rising from the stove and will, consequently, throw them outwardly instead of throwing them upwardly against the hood or disk as would #be the case if the fan were rotated in the opposite direction. If so desired, the blades may be set so that their outer end edges will be vertical in which event the direction of rotation will not be so important inasmuch as rotation in either direction will forcibly propel the currents laterally from the space between the stove and the hood or deflecting disk. The base ring should be of such diameter than it will iit the top of the heater closely and thereby furnish a iirm support for the hood but may be instantly withdrawn `from the heater when desired. The guards or supports extending between the base ring and the hood effectually prevent persons coming in contact with and being injured by the fan blades, while at the same time they effectually support the hood without obstructing 4the escape of the heated llO currents under the influence of the fan. The device may be applied to radiators or other forms of heating unitsand may be support; ed on a separate stand extending over the heating unit While the motor may be at the lower end of the fan shaft but, for the greatest, efeency, the, fan, shaft shouldy be approximately Vertical.

Having thus described my invention, what isclaiined as new is:

l. A'deyiee forthe purposeset forth com,- prsng basememben 'afdptedft'o tn the top' ofA a` heater, rising from said member, a,y hod supported the'upperl,

ends ofsaid guards, and a positively driven fan arranged between the hood and the base member.

2. A device for the purpose set forth Comprising a base member adapted to engage the top of a heater, guards rising from said member, a hood supported by said guards, a bearing at` the center. of said hood, and a positively driven fanjournaled in said bearing and arranged to operate between the hoodand the top of the heater.

In' testimony whereof I aiiX my signature.
