1 Claim.

My invention relates to improvements in humidifiers, and the object of the invention is to devise a simple, cheap construction which will eliminate the gurgling sounds usually produced in the generation of steam, and it consists essentially of the arrangement and construction of parts all as hereinafter more particularly explained.

Fig. 1 is a perspective view of my humidifier showing the pipe extending between the humidifying chamber and generator broken away intermediately of its length.

Fig. 2 is a longitudinal sectional view through Fig. 1.

In the drawing like letters of reference indicate corresponding parts in each figure.

1 indicates a fragmentary portion of a wall of the fire pot of a furnace. 2 is a pipe extending through such wall and leading at one end to the generator 3 located within the fire pot and at the opposite end to the humidifying chamber 4. The lower or bottom wall of the generator is stepped as indicated at 3 to increase the heat absorbing surfaces and also the body of metal whereby the heat is retained. The chamber 3 located within the generator has a bottom portion 5 which is flush with the bottom of the pipe 2 and at the inner end of such surface is provided with a stepped down surface 5*. The bottom end of the generator from such stepped down portion is inclined upwardly to the rear end of the generator. By this means any sediment which precipitates in the water collects directly adjacent to such stepped down portion 5 and is, therefore, easily removed.

The humidifier chamber 4 is substantially cylindrical, one end being secured to the opposite end of the pipe 2 as previously stated, the outer end of the chamber being reduced as indicated at 4 into which reduced portion is secured a drip pipe 6, the lower portion of which is also fiush with the bottom of the generator and with the bottom of the pipe 2. By this means an even surface is provided extending from the front portion of the generator through the pipe 2, humidifying chamber 4 and drip pipe 6. The chamber 4 is provided with an upwardly extending boss 1 in which is formed an inclined passage 1 the surface 1 forming a directing bafile for directing the steam generated up through a pipe 8 into a casing 9 provided with a fioor grid In which is, of course, flush with the floor of the chamber which it is designed to humidify.

II is a water supply pipe. I2 is a drip valve preferably of needle construction and adapted to drip water a drop at a time into the cup l3 which is connected by a short pipe I4 extending through the top wall of the humidifying chamber 1 so as to supply water into the interior of the humidifying chamber.

In operation the valve I2 is set so as to drip water very slowly into the humidifying chamber so as to maintain a very shallow depth of water l5 extending through the pipe I2 from the humidifying chamber into the generating chamber as indicated in Fig. 2. By this means steam rising from the generating chamber is mostly directed up by the bafile wall 1 into the pipe 8, to the casing 9 and through the grid l0 into the room. If there is an over supply of steam it merely passes out through the drip pipe 6. I

By this means the gurgling sound which is caused in the generator through the over production of steam is eliminated.

It may-be stated, however, that the supply of water by the drip valve l2 can be so regulated that a mere film of water i3 is formed so that most of this water is directly converted into steam to pass up through the grid in for humidification. 7

What I claim as my invention is:-

The combination with a generator extending into the interior of the furnace and provided with aslightly stepped down portion and a raised portion, ofa pipe extending into the generator and having its lower'surface flush with the raised portion in the generator, a humidifier into which the outer end of the pipe fits and having its lower interior portion flush with the lower surface of the pipe so that the lower surface of the aforesaid pipe, lower interior portion of the humidifier, and raised portion of the lower surface of the generator are in a line and an inclined baille formed in the humidifier, a pipe leading upwardly from immediately above the inclined baflie, a drip valve and pipe leading into the upper portion of the humidifier and a drip or drain pipe having its lowermost surface fiush with the lowermost surface of the generator.
