Specification of Letters Patent.

Patented Dec. 27, 1910.

Application led December 24, 1908. Serial No. 469,122.

To all whom it 'may concern:

Be it known that I, DANIEL HOWARD HAY- wooD, a citizen of the United States of America, and a resident of New York, county and State of New York, have in vented certain new and useful Improvements in Carbureters, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

My invention relates to improvements in carbureters in which volatile liquids are evaporated and the product therefrom and intermingled with air or other gaseous or aeriform fluid to be enriched. In one form of such apparatus fibrous or absorbent material is employed for receiving the volatile liquid fed to the apparatus.

It is the main object of my present invention to provide a simple and efficient form of automatic control for the liquid feed, whereby the fibrous or absorbent material may be maintained at a uniform degree of moisture without being flooded, and a uniform quality of gaseous mixture thereby produced without the apparatus requiring constant attention.

My invention also consists in certain details of construction and arrangement of parts as will more fully appear hereinafter, and in order that my invention may be thoroughly understood, I will now describe an embodiment thereof, having reference to the accompanying drawings, and will then point out the novel features in claims.

In the drawings: Figure 1 is a View in central section of a carbureter embodying my invention. Fig. 2 is a view in horizontal section therethrough. Figs. 3 and i are detail views of a valve employed. Fig. 5 is a view in central vertical section through a modified form of the apparatus. Fig. 6 is a view in horizontal section therethrough. Fig. 7 is a detail view in side elevation of a part of the apparatus.

The apparatus in general comprises a shell and a plurality of trays which sub-divide the same horizontally into a plurality of chambers. The shell shown consists of a vertical cylinder 10, a base 11, and a removable cap or hood 12. The trays comprise a substantially cylindrical portion 13, a bottom 14, a perforated top 15, and an in'en he space between the bottom 14: and the diaphragm 16 is preferably filled up with an absorbent fibrous material 17,-such as cotton waste,-while capillary threads 18,- such as wicking or the like,-are woven backward and forward between the two

perforated diaphragms

15 and 16. In the eX- ample of my invention shown in Figs. 1 and 2 the trays are supported upon trunnions 19, here shown in the form of hollow pipes, the said trunnions being arranged considerably to one side of the center of the trays and being conveniently disposed alternately upon opposite sides ofthe center, as will clearly appear by reference to Fig. 1. The trays are provided with counterbalancing weights 2() which are arranged in each case upon the short side of the tray,-that is to say, upon that side of the center which comprises the smaller portion of the tra the said weights being intended to be sufficient to normally lift the other end of the tray into a substantially horizontal position. The tubes or pipes 19 which constituteV the axis or supports for the trays are preferably provided with slots 21 therein, the said slots opening into the space in the trays between the bottoms 14 and the diaphragm 16, whereby liquid to be evaporated may be fed into the trays therethrough. A valve piece 22 is disposed upon the end of each said pipe 19, the said valve piece being preferably located at the exterior of the apparatus. This valve .piece has an opening therethrough which communicates through a lateral opening in the said pipe with the interior thereof, and the face of the said valve piece engages a valve seat 23 adjustably secured upon a casing 24 to which a supply pipe 25 is connected.

Liquid to be evaporated, which is supplied through the pipe 25, valve piece 22, and pipe 19 to the interior of a tray, is first absorbed by the material 17 and is then carried up by capillary attraction along the threads 13. The trays are intended to be so balanced that when the fibrous material is saturated to a sufficient degree the increase of weight carried by the tray will be sufficient to over-balance the counterbalancing weight 20 and thereby to depress the end of the tray which is opposite to the said weight 20. The effect of this will be to rotate the pipe 19 which carries the tray, to a sufficient degree to move the valve piece 22 across its seat' 23 to cut off further supply. After the liquid carried by the tray has been evaporated to a sufficient degree to so reduce the weight carried by the tray that the counterbalancing weight 20 will over-balance the opposite end of the tray, then the said tray will rock upon its support in the opposite direction to that just noted, the weighted end moving downward and the opposite end moving upward. This will reverse the position of the valve piece and will bring the ports and passages of the valve and its seat again into register so as to permit a further supply of liquid to be fed into the tray. By the foregoing means I am enabled to automatically feed the required quantity of liquid into the apparatus in exact proportion to that evaporated, whereby the fibrous material therein may be maintained at a uniform degree of moisture.

In the form of apparatus shown in Fig. 1 the trays are separated from each other by means of fixed diaphragms 36, the said diaphragms having openings 26 therethrough located alternately upon opposite sides of the apparatus, the trays having flat sides 27 between which and the cylindrical shell 10 are formed spaces or channels substantially corresponding to the said openings 26, whereby a continuous channel of zig-zig form is provided throughout the apparatus. A supply pipe 28 for air or other aeriform or gaseous fluid to be enriched is connected with the apparatus at the lower portion of the shell or casing so that the'air or the like will enter the lower-most chamber to thereby pass across the capillary threads and up through the opening 26, past the flat side 27 of the second tray, through the capillary threads of the second tray and so on, the passage of the current of air causing the kliquid to be rapidly evaporated from the capillary threads and the vapor to be intimately mingled with the said air. The mixed product is delivered through a delivery pipe 29. I have shown means for automatically controlling the admission of air through the pipe 28 so that air will only be admitted as the product is dra-wn off through the pipe 29, the same consisting of a pressure operated valve 30, the motor therefor being' connected by means of a branch pipe 31 with the said discharge pipe 29.

In Figs. 5 and 6 I have shown an appa` ratus in which the trays are held stationary, small trays or pans 32 of liquid being disposed beneath each tray. The pans are pivoted upon hollow trunnions 33 which connect with the supply pipe and are provided with counterbalance weights 34 similar to the weights 20 of the construction shown in Fig. 1. The bases of the trays in the form of` apparatus shown in Figs. 5 and 6 have a depressed portion 35, the lower part of which has openings therethrough and is received within the pans 32. Liquid is fed into the pans instead of directly into the trays, and the liquid is absorbed through the openings inthe portions 35 by the ab` sorbent material 17 in the trays, and is thence carried by the capillary threads as in the other form of apparatus. vWhen the absorbent material has absorbed all of the liquid it can carry the liquid will accumulate in the pan until the weight thereof will overbalance the weight 34 and will thereby carry off further supply. Upon evaporation taking place in the apparatus and further liquid being absorbed from the trays to take the place thereof, the weights 34 will finally be suiicient to reverse the position of the trays to once more open the supply.

The principle of operation of the two forms of apparatus will be seen to be entirely similar, the diierences being only structural. In bot-h cases the fibrous material is maintained in a substantially uniform condition of moisture, liquid fed to the apparatus in excess of that required, serving by its weight to close the inlet against further admission of liquid.
