5 Claims.

My invention relates to air-current attachments for heating radiators.

More particularly, embodiments of my invention are designed for assembly with heating radiators by direct support upon the heating radiator, securement being preferably had by hook-like elements or equivalent embracing a portion of the radiator assembly.

Preferred embodiments of my present inven tion comprise a housing enclosing and supporting one or more motor and fan assemblies, a septum provided with an opening or openings correlated respectively with such fan or fans, and ingress openings in the housing communicating with the interior of the housing above such septum.

Commercial embodiments of my invention comprise the stated essential elements combined as a unitary assembly, thus affording pre-fabrieating and assembly in a factory or the like, and facilitating installation relative to a radiator, removal of the assembly as a unit for inspection, cleaning and repair, etc. Desirably, such unitary assemblies may be of standard lengths of casing, the number of the motor-fan units being determined by the size of the casing and the motor-fan unit output.

During the stage of operation of the fan, assuming steam or other suitable heating medium to be supplied to the radiator, air is projected downwardly and in heat exchange relation with the heating surfaces of the radiator, thus increasing the effective heat units delivered by the radiator, the air projected by the fan or fans being induced through the air ingress openings of the casing and bringing about the positive circulation, additionally to rise of temperature, of the air of the room or other space served by the radiator.

Further features and objects of the invention will be more fully understood from the following detail description and the accompanying drawing, in which- Fig. 1 is a side elevation, partly broken away in vertical section for the sake of clarity, of a preferred form of a preferred embodiment of my invention.

Fig. 2 is a sectional view on line 2-2 of Fig. 1.

Referring to the preferred embodiment shown in Figs. 1 and 2, the illustrated type of my invention comprises a casing It! having a substantially fully open bottom I I, members such as the angle plates I2, I2, respectively having one angled portion, see In, welded or otherwise secured to the material of the opposite sides I3, I4, of the casing ID, the projecting angled portions, see I2b, serving to rest upon aligned top face portions of the heating radiator assembly, R, usually of sections as shown in the drawing. By such or equivalent provision of means, the casing I0 is arranged to 5 engage and be supported by such engagement with the upper face portions of a radiator assembly.

If desired, stability of support of the casing I0 is had by lowerly extending the opposite sides I3, ,10 I4, of the casing III, as is indicated at I3a, I la. Also, hook-like members, see I5, adjustably secured and carried at their fixed ends, see I5a, as by means of nut and threading, may beemployed, as appears more fully hereinafter, for anchoring 5 the casing relative to the radiator assembly R.

One or more motor and fan assemblies maybe utilized, the illustrated embodiment of Figs. 1 and 2 showing two such assemblies, each motor being indicated I6 and its associated fan I'I. Such motor-fan assembly is suitably housed within and supported by the casing I 0, as by means of a bracket I8, one angled portion IBa of which may be secured by bolt and nut, or equivalent, to, say, the inner face of the rear side I3 of the casing or housing I0. Preferably, each motor-fan assembly is resiliently suspended, conveniently had by suspending elements I9, I9, desirably of one length of resilient steel or other suitable metal or other material, suitably bent, and riveted or, otherwise supended from the free angled portion of its associated bracket I8.

Coordinated with such fan I! I provide a septum 20 extending imperforately end to end within the casing or housing II! from one lateral side I3 to the opposite lateral side I4 excepting the one or more openings 201, corresponding to the number of fans, which opening 20a. each has a diameter slightly larger than the efiective diameter of the therewith coordinated fan. If desired, the edge of each opening 200. may be provided with a cylindrically extending flange, serving in coordination with the blades of the associated fan to form a tunnel for the projected circulation therethrough of air. 1

Ingress openings for air are shown in the illustrated preferred embodiment at El, in this instance disposed wholly in one lateral side, i. e., the front side Id of the casing, the remaining sides of the casing I0, i. e. its top 22, its opposite end sides 23, 24, and its rear side I3 being imperforate; each of such air ingress openings ii is effectively located above the septum 20. However, if desired, air ingress openings may be provided in the material of more than one side, such 7 turn in heat exchange relation with the heating surfaces of the radiator assembly R, a suit- ,able heating medium being assumed to be supplied to the radiator assembly,

The material of such septum 20 may afiord, as shown, dual functioning, i. e., for the anchoring and adjustable positioning of the securing hooks l5, IS, in addition to its above stated purposes. 'l'ireierably, .also, as shown, the septum 20 is spaced a predetermined clearance from the heating surfaces of the radiator assembly, as by means ofspacers, see 25, conveniently of U-bent plates, the base of the U-formation engaging the fiat under face of the septum 20 and embracing the body portion of the associated hook-like member IS, the free edges of the U-formation being usually rectilinear to rest upon usually aligned top faces of the radiator assembly, or

configurated in correspondence to the configuration of the top faces of the radiator assembly.

operation the air of the room or other space is Embodiments of my invention find particular I The period of actuation of the one or more motor-fan assemblies may be controlled by a manually operated switch, diagrammatically indicated at 26, which may provide for multiple speed actuation. Advantageously, such current controlling switch 26 may be thermostatically. responsive, most advantageously responsive ther mostatically to differential temperature setting, as for example, providing for full speed'of each motor-fan assembly for a set minimum temperature, half or other partial speed for a set intermediate temperature, and off for a set maximum temperature.

-Under the stages of operation of the fan assembly of my, attachment to a heating radiator, air induced through the ingress openings is projected downwardly upon and in heat exchange relation to the heatingfsurfaces of the radiator assembly, and generally toward the floor of the room or other space served by the radiator. The greater the speed of any given fan assembly the more effectively the thus heated air is projected to such floor, thus correspondinglyenhancing,

desiring such objective; In all such stages of fan re-circ'ulated as Well as increased in temperature,

The resilient mounting of the motor and fan assembly serves to minimize mechanical trans mission of vibration to thecasing proper, and

silence otherwise, incident to the actuation of the motor and of the fan, also to minimize mechanical shock or stresses to the motor or fan incident to handling of the assembly, etc.

By covering and/or enclosing the top of the radiator assembly, my invention serves to conceal the radiator assembly, which objective may be further attained by extending the front side of the casing to extend forwardly of or in front 1. The combination with a radiator assembly,
