HUMIDIFYING ATTACHMENT FOR RADIATOBS.

To all whom it may concern.-

Be it known that'I, PHILIP 'T. JAoKsoN. of the city of Toronto, in'the'county of York, Province of Ontario, Canada, have invented certain new and useful Improve ments in Humidifying Attachments for Badiators, of which the following is a specification. i

This invention relates to devices for increasing the quantity of water vapor held suspended in the air of buildings heated artificially and particularly to devices for use in connection with heating means such as hot water and steam radiators to take advantage of the heat thereof to obtain efficient evaporation, and my object is to devise humidifying means which will be as inconspicuous as possible, which will not occupy any valuable space, and which will possess very high efficiency, and in which the water containers shall be as nearly dust proof as possible.

I attain my object by means of the constructions hereinafter described and illustrated in the accompanying drawings in V which Fig. 1 is a front elevation of a radiator, partly broken'away, provided with my im proved humidifying attachment;

Fig. 2 an end view of the radiator partly broken away;

Fig. 3 an enlarged section through one of the troughs of the attachment, and the water supply conduit;

Fig. 4 is a front view of in Fig. 3;

Fig. 5 a front view of one of the plates shown for supporting the rod from which the absorbent sheets are hung; and

Fig. 6 a plan view, of the water troughs the parts shown for a live section radiator and the conduit to which they are connected.

In the'drawings like numerals of reference indicate corresponding parts in the different figures.

In the drawings I show a radiator constructed as usual of a plurality of sections 1, such sections being formed of a plurality of loops' as shown. 2is a water distributing conduit, which. may be connected with a source of supply in which a constant water level is maintained in any well known manner but which is shown as connected with the water space of the radiator itself to draw its supply therefrom as hereinafter described. This conduit communicates with Specification of Letters Patent.

and hooks 9 secured to the Patented May 30, 1922.

the rear ends of a plurality of troughs 3 adjacent their bottoms and is of small diameter relative to the height of said troughs. These troughs are narrow and high relative to their width, their length and other proportions being such that they will extend through from the back or front of the radiator, as the case may be, to a point adjacent the other edges of-the radiator sections. The height of these troughs must be small relative to .the' height of the radiator so as to provide sufficient space above the tops to the troughs for the projection to a 'suitable height of absorbent sheets as'hereinafter re ferred to.

While any suitable means may be pro-' vided to support the conduit and troughs in position as shown above the nipples connects ing the radiator sections, at any desired. level, I prefer to employ the construction shown comprising an angle bar 4' lying against the rear edges ofthe radiator sections and a bar 5 fitted" between the loops of thesections, said bars running lengthwise of the radiator and being secured together by bolts 6. The bars are thus easily adjusted to vary the vertical position of the troughs and to level up the conduit whenever necessary.

Into each trough clips the lower part of a sheet 7 of suitable absorbent material. Heavy blotting paper, with or without a reinforcement of textile fabric, I find to be suitable for my purpose. If these sheets are heavy enough and not too tall, I find that they may stand unsupported in the troughs with their upper parts extendingsufliciently above the same to form evaporating surfaces.

- These sheets should be in height at lea'st equal to the height to which capillary action will raise the water. I

If the sheets of absorbent material are as high as stated and which is necessary to secure a maximumof evaporating capacity, I find it preferable to provide means for hanging them from-theupper'parts of the radiator sections. I show for this purpose a rod 8 connected with the radiator sections and extending from end to end of the radiator, upper ends of the sheets 7. To form a suitable attachment for the hooks, I provide each of the sheets 7 with a metallic reinforcement or binding 10. to which reinforcement the hooks are suitably secured. Each hook is preferably provided with shoulders 1l andl2 at diflertion shown satisfactory in most cases.

ent distances from the reinforcement so that each sheet may be held suspended at will in two different positions, either immersed in or just clear of the surface of the water.

The shoulders are preferably so positioned that each sheet may be suspended with its lower edge close to the bottom ofthe trough or with its lower edge raised above the water level in the trough.

While the rod 8 may be held in position in any suitable manner, I find the construc- The rod passes between two loops of each radiator section and at each outer end is supported by two plates 13 and 14 which lie respectively against the inner and outer surfaces of the end sections of the radiator and are clamped against the same by bolts 15. When the rod 8 is engaged with the lower shoulder of the hook 9 thus holding thesheet free of the surface of the water, the sheet will still be retained between the sides of its trough which thus act as guides when the sheet is lowered to dip into the water. It is desirable to exclude dust as far as possible from the water troughs 3. therefore contract the sides of each trough adjacent its upper edge as indicated at 18, so that the sides substantially contact with the sides of the absorbent sheet, sufficient space, however, being left to, permit of the introduction and withdrawal of the absorbent sheets. As there is a possibility that contact of the upper edges of the trough with the sides of the absorbent sheetmight result in water drawn up by the capillary action of the sheets being transferred to the upper edges of the trough to flow down outside the trough, I prefer to outwardly flare the upper edges of each trough as indicated at 19.

To facilitate the introduction of the lower edges of each sheet 7 into the trough, I.

proportion the free end and the sides of each trough so that the sides extend above the free end of the trough as shown particularly in Figs. 3 and 4. If the lower part of the edge of the sheet be introduced between the sides above the free end, the sheet is readily pushed into position between the upstanding edges and is then readily dropped to its operative position within the trough and supported'by the rod 8.

To hold each sheet as far as possible out of contact with the radiator sections, I preferably provide flanges 20 along the lower edges of the metal reinforcement 10 of each strip.

To facilitate the handling of the attachment and to avoid strain on the connection betweenthe troughs and'the water conduit, I prefer to connect the ends ofthe troughs adjacent :the conduit by means of a plate 21 to which the troughs are soldered or otherwise suitably connected. .This plate an upward extension of an may in fact be I from which the conduit is integral sheet rolled.

In practice variations of the means for supporting the absorbent strips and the troughs with their conduit will be necessary owing to variations in the construction, divisions and arrangement of various radiators, and such variations would fall within the scope of anyinventioh.

The conduit 2 is shown as connected with the water space of one of the radiator sections by a pipe 22 in'which is located a valve 23, manually controllable or otherwise, by means of which water may be supplied as needed from the interior of the radiator to be evaporated in the humidifying attachment. v

The combination with a sectional radiator of a humidifying device comprising a water duet; a plurality of substantially parallel narrow troughs each communicating at one end with the duct and. adapted to lie between the sections of the radiator above the lower connect-ions thereof. and sheets of absorbent material having their lower parts lying in said troughs and extending above the same between the radiator sections to form evaporating surfaces, said troughs being of small height relative tothe height of the radiator, and the height of said troughs also being small relative to the height to which capillary action will raise the water in the sheets.

2. The combination with a. sectional radiator of a humidifying device comprising a plurality of substantially parallel narrow troughs adapted to lie botweenthe sections of the sectional radiator, said troughs being of small. height relative to the height of the radiator; and a tubular duct of. small diameter relative to the height of the troughs communicating with each trough at its end adjacent its bottom.
