WATER-EVAPORATOR.

Specification of Letters Patent.

Patented Apr. a, mic.

Application filed March 30, 1917'. Serial No. 158,594.

To all whom it may concern:

Be it known that T, SVEN LINDBERG, a citizen of the United States, and a resident of Galesburg, in the county of Knox and State of Illinois, have invented a new and useful vVater-Evaporator, of which the following is a specification.

The invention relates primarily to a device attachable to a hot-air pipe, adjacent a floor-register, and adapted to contain water to be heated by the hot. air passing from said pipe to and through the register, whereby to humidify the air in a room.

As the nature of the invention is more fully disclosed it will be evident that its use is not limited alone to hot air systems of heating, but that it may be used with equally as good results in connection with the radiators of steam, vapor and hot water heating equipments.

The principal object of the invention is to improve the construction and to increase the capacity, utility and efficiency of devices of this nature.

The invention consists in the improvements hereinafter described.

In the accompanying drawings, which illustrate a preferred and a modified embodiment of my invention:

Figure l is a perspective View showing the novel evaporator;

Fig. 2, a perspective, one of the side pieces of the water pan removed in order to more clearly show the interior structure;

Fig. 3, a vertical longitudinal section showing the evaporator as it. appears when in position for use; and

Fig. 4c, a plan view.

Considering the drawings in detail and referring to each element and, where necessary, to each part thereof by a distinguishing reference character, 2, 2 designate portions of a floor; 3 indicates an ordinary register-plate removably supported thereby and provided with openings 4 for the passage of air; and 5 denotes a hot-air pipe the box-top of which is provided with flared sides 6, flared ends 7, and a flange 8 operating as an open bottom.

The preferred type of my improvements is shown best in Fig. 1, wherein 9, 9 designate the outer, flared end-walls and 10, 10 the outer, flared side-walls of a water-pan 11 the inner side-walls of which are designated by 12 and the inner end walls by 13. The adjacent inner and outer walls are united at their lower edges whereby to provide a continuous water channel 14.

15, 15 indicate'pockets each of which has an open top which communicates with the channel 14 as follows: The side-pieces of each pocket extend upward substantially to the top of the pan 11, but their edges are open. A suitable number of registering slots 16 are cut in each end 13 and the vertical edges of the pocket extensions 17 are soldered one at each side of each slot, to the adjacent wall 12. The water may thus pass freely from the pan, through the several slots 16, into the watencirculating channels 18, and thence into the pockets 15.

In operation, the channel 14 having been filled with water a portion thereof will flow through the slots 16, pass between each coacting pair of pocket-extensions 17 and thence flow into the communicating pockets. Each pocket while of relatively small capacity contains a comparatively great heating surface which is constantly subjected to the hot air coming through the source of supply 5. The pockets being formed of metal, it of course follows that when their portions which lie below the bottom of the pan become heated, the heat will be communicated or pass upward to the extensions 17 which will thus aid in heating the water contained in the pan. The water in each pocket thus becomes quickly heated and it will rise and give off moisture. As it rises the pocket will fill with the cooler water, and the heating processes continue in the manner described, the water, it being particularly noted, being constantly circulated. The pan per 86 and the extensions are constantly subjected to the hot air coming from the pipe 5, and they of course become heated thereby and thus maintain in a warm condition all the water contained in the channel and between the extensions. The water will be quickly evaporated and the relative humidity of the air in the room greatly increased, making it much more sanitary and healthful. Dry air being most difficult to heat the device is of considerable economic value as regards fuel consumption. Furniture and musical instruments are damaged greatly by hot, dry air. This is especially true of pianos, the sounding boards of which become cracked, and the veneers and action-parts of which become warped, unglued and checked, whereby the instrument becomes practically worthless.

I claim as new and as my invention the t'ollowing, to-wit 1. In an evaporator, continuous inner and outer walls providing a continuous water channel opposite portions of the inner wall being provided with registering slots, and a plurality o1 plates attached each to the inner walls and at the edge of one of the slots, each adjacent pair of said plates thus forming a channel communicating with said continuous channel, and the lower portions of each coacting pair of plates united :to form a water pocket.

2. In an evaporator, an inner wall comprising sides and ends, the latter provided .With registering vertically arranged slots, an outer wall completely surrounding said inner wall and together therewith providing a continuous water-channel, a bottom common tosaid walls, and a plurality of heating-slates arranged'in spaced pairsand attached each to said inner walls and at the edge of one of the slots therein, each adja- 3.1n' an evaporator, continuous inner and Outer walls providing a continuous water channel substantially rectangular in outline, opposite portions of the inner wall being provided with registering slots, a bottom common to said walls, and a plurality of plates arranged in coacting pairs extending upward to approximately the-top .of the pan and ashort distance below said bottonn each pair of plates secured to said inner .wall and providingcommunication between opposite sides of said continuous channel, and the edges .of the slower portions of the pairs ,of plates united to form water pockets.

In testnnony whereof I hereunto set my 7 hand :this 27th day vof .March,'19l7.
