1 Claim.

The present invention relates to new and useful improvements in wet reagent feeders and has for one of its important objects to provide, in a manner as hereinafter set forth, a device of this character which is adapted to be expeditiously and accurately adjusted to discharge the reagent at any desired rate of speed.

Another ver important object of the invention is to provide a feeder of the aforementioned character comprising adjustable means for electrically heatin or warming the reagent to any suitable temperature.

Still another important object of the invention is to provide a reagent feeder of the character described comprising a discharge spout which is adapted to be removed when desired for cleaning or replacement.

Other objects of the invention ar to provide a reagent feeder of the character set forth which will be comparatively simple in construction, strong, durable, highly efficient and reliable in use, compact and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawings wherein like characters of reference designate correspondin parts throughout the several views, and wherein:

Figure 1 is a view in front elevation of a reagent feeder constructed in accordance with the present invention.

Figure 2 is a View in side elevation thereof.

Figure 3 is a top plan view.

Figure 4 is a vertical sectional view, taken substantially on the line 44 of Figure 2. v

Figure 5 is a vertical sectional view, taken sub stantially on the line 5-5 of Figure 1.

Figure 6 is a diagrammatic view of the electric heatin or warming system.

Referring now to the drawings in detail, it will be seen that the embodiment of the invention which has been illustrated comprises a container for the reception of the wet reagent, said container being designated generally by reference numeral I. The container I may be of any suitable material and of an desired capacity.

The container I include an elevated bottom 2 thus providing a supportin base or skirt 3. The container I further includes a top portion 4 having hingedly mounted thereon a cover or lid 5. Any suitable means, as at 6, may be provided for securing the cover 5 in closed position.

The bottom 2 of the container I is provided is a variable rheostat with a discharge opening I the Walls of which are formed to provide a seat. The container bottom 2, it will be noted, slopes toward the discharge openin I.

Rising from the top portion 4 of the container I is a boss or neck 8. Threadedly mounted in the neck 8 is a needle valve 9. At its lower end, the needle valve 9 terminates in a comparatively long point In which projects all the way through the discharge opening I. At its upper end the needle valve 9 terminates in an operating handle II. The needle valve 9 is operable in a tubular guide I2 which is provided therefor on the adjacent wall of the container I.

Th container skirt 3 has formed therein an opening I3 which accommodates a discharge spout I 4. Fixed on the bottom of the spout I4 is a bracket I5 which is secured by a screw I6 to the skirt 3. It will thus be seen that the spout I4 may be expeditiously removed when desired.

Mounted beneath the bottom 2 of the container I is an electric heater IT. This heater may, of course, receive electric current from any suitable source. Mounted on one side of the container I I3 which is interposed in the electric circuit to the heater I I for controlling or regulating said heater. A hinged door I9 permits access to be readily had to the space or chamber which is provided beneath the container I by the elevated bottom 2.

It is thought that the operation of the device will be readily apparent from a consideration of the foregoing. Briefly, the wet reagent is placed in the container I and flows at the desired rate through the discharge opening I from which it drops into the inclined spout I4. The discharge of the wet reagent through the opening 1 is controlled through the medium of the needle valve 9, the construction and arrangement being such that any desired adjustment may be rapidly and accurately made and held. Further, the comparatively long point In of the needle valve 9, by reason of the fact that it extends clear through the opening 1, keeps said opening clear at all times. As hereinbefore stated, the spout I4 may be expeditiously taken oif for cleaning or replacement by simply removing the screw I6. The electric heater I'I maintains the reagent at the proper temperature to flow freely. The temperature is regulated through the medium of the rheostat l8.

It is believed that the many advantages of a wet reagent feeder constructed in accordance with the present invention will be readily understood, and although a preferred embodiment of the dean open trough extending at an inclination through the second-named opening and positioned beneath the first-named opening for receiving the reagent therefrom, a bracket depending from the trough, and means detachably securing said bracket to the container for removably securing the trough in the second-named opening.
