tains to make and use the same.

This invention relates to a new and useful improvementin carburetors and it consists in the construction and arrangement of parts hereinafter described and definitely pointed out in the claims.

The aim and purpose of this invention is the provision of an improved carburetor, having provision for retaining a constant and uniform supply of gas, and further to construct a receiving tank or reservoir for the gas which will be automatic in its operation and simple in its construction.

A still further object of the invention is to so arrange the carburetor that an increased evaporating surface may be had in a comparatively small apparatus, and finally in the details of the construction hereinafter described for rendering the apparatus exceedingly simple for general use. These objects are obtained by the construction illustrated by the accompanying drawings, and in which- Figure 1 represents a vertical section of the apparatus including the gasometer and Fig. 2, is a detail elevation of the out off valve.

In the drawings A represents a carburetor casing, formed with horizontal dividing walls B dividing the interior of the easing into three compartments A A and A The upper portion of the interior of the casing is formed with an inclined partition or cap 0 inclining downward to a common center and located a short distance from the top B thereby forming a space D.

F represents a feed tube passing through the top 13*, the partition G andinto the chamber A.

F represents a feed tube arranged beside the feed tube F, extending into the chamber A and F represents a feed tube entering cham ber A These tubes F, F have the perforations a, a a therein located at points above the normal height of the liquid in the compartments.

G represents a suitable wicking extendlng up from the bottom of the compartment A through suitable opening in the edge of the partition 0 and carried down the face thereof resting on vertical ribs 0 formed on the upper face of the partition 0. The partition is also provided'at the highest point between the ribs with suitable apertures.

Arranged across the interior of the compartments A A are supporting rods 71, located at points'adjacent to the upper end or top of I the compartments. Over these rods h is passed the wickin g H, the rods being arranged so that the wicking will be carried up from the bottom over the rods down and up unt1l it reaches the opposite side, the arrangement being substantiallythe same in each compartment. Instead of carrying the WlOklIlg directly down at the center it is spanned or carried over the central adjacent rods forming a flat surface at this point.

I represents an air supply pipe leading into the space D through the cap the same being connected with any suitable air supl in a aratus. p Lod ate d within the compartments A, A A are floats K'having stems extending up through the tubes F, F F at the top of the apparatus. The stems may have a series of indicating marks thereon and pass through the caps K of the tubes. The liquid within the compartment will force the float up, the

stems within the tubes projecting beyond the.

end thereof and indicating the height of the liquid within the compartment.

Lis the discharge pipe having a series of branch pipes Z, Z and Z extending into the carburetor at different elevations, the pipe Z extends up into the drum N at which point it is provided with a suitable cut ofl: m of the following construction: The discharge end of the pipe L is formed with three or more apertures O and has pivoted thereon a cut ofif valve 0 having three corresponding apertures registering with the apertures of the discharge end of the pipe. The valve 0 has aweighted arm 0 extending out from one edge thereof, to which a suitable chain P is attached, the opposite end of the chain being carried up and secured to the dome of the drum. Ears 0' are formed on the opposite side of the valve 0' which engage a suitable lug 0 on the nozzle on the pipe L. By this means the movement of the valve is limited.

In operation the caps of the feed tubes F, F and F are removed. Gasoline is filled into the compartments, that passing through the tubes F, F entering the compartments A A \Vhen the compartments are filled to a point slightly below the rods h the caps are replaced on the filling tubes and air is forced in through the tube 1. The cock in the pipe L is then opened and the gas allowed to pass therethrough. The wicking G, by capillary attraction, carries the gasoline into the compartment D at which point it is vaporized, the contact of the air being both above and below the wicking, by reasons of the ribs 0 which hold the wicking above the partition. All drippings from the wicks G are caught and held by the upper or outer faces of the ribs, while the apertures in the partition 0 allow the air to pass therethrough onto the gasoline compartments below. hen the amount of gasoline in the compartments has been reduced the cocks in the uppermost pipes are closed and the lowermost pipes opened so that the dense vapors near the surface of the gasoline in the lower compartments will escape. By this means the density of the vapors and consequently the richness and regularity of the gas may be retained and supplied to the gasoineter irrespective of the quantity of the gasoline in the carburetor. By placing the wicking H in the compartments in the manner above described an increased area or surface for the gasoline, is exposed to the action of the air all of which tend to enrich or increase the density of the gas. The perforations in the feed pipes are arranged to admit air to the compartments A A and to allow the gas to escape when the lower pipes are closed. As the gas escapes through the pipe L it enters drum M, the valve 0 being normally opened by reason of the weighted arm. As the drum or hell rises carrying the chain P up the weight is lifted closing the valve shutting off the supply of gas. By dividing the carburetor easing into two or more compartments an increased area or exposed surface is obtained, the vapor passing up from the lower compartments through the 3 tube E when the pipe Z is closed.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-

1. In a carburetor, the combination with the casin g, having horizontal partitions therein dividing the interior thereof into a series of compartments, feeding tubes leading into the respective compartments, those for the lower compartment passing through the compartments above and formed with a series of perforations at points Within the uppermost compartment, a suspended wicking above the upper compartment, wicking in the lower compartments, extending from the bottom to the tops thereof in a series of folds orloops, an air supply pipe, at discharge pipe entering the top of the casing, a series of branch pipes leading from the said discharge pipe and entering respectively the respective compartments and a gasometer in which the discharge pipe leads, substantially as described.

2.'In a carburetor, the combination with the casing, having two or more compartments therein arranged one above the other and having com munication with each other, means for supplying the compartments with a volatile liquid an inclined perforated partition above the upper compartment formed with openings therein, a suitable wick extending from the compartment below the partition up to and over the inclined partition, horizontal supports in the compartments near their upper ends arranged at intervals, wicking supported by said supports and extending down toward the bottom of the compartments, means forsupplying air to the compartments, and a series of discharge pipes entering the respective compartments and leading into a common discharge pipe, substantially as described.

3. In a carburetor, the combination with the casing having horizontal partitions therein dividing the interior thereof into a series of compartments, feeding tubes leading into the respective compartments, those for the lower compartments passing through the compartments above, and formed with a series of perforations at points within the uppermost compartment, floats in the respective compartments having stems passing through and above the tubes, a suspended wicking above the upper compartment, wicking in the lower compartments, extending from the bottom to the tops thereof in a series of folds or loops, an air supply pipe, a discharge pipe ontering the top of the casing, a series of branch pipes leading from the said discharge pipe and entering respectively the respective compartments and a gasometer in which the discharge pipe leads, substantially as described.

In testimony whereof we affix our signatures in presence of two witnesses.
