CARBURETER.

SPECIFICATION forming part of Letters Patent No. 671,052, dated April 2, 1901.

Application filed October 5, 1900. Serial No. 32,129I (No model.)

To all whom it may 0071/0071711:

Be it known that I, FRANZ KELLER KURZ, a citizen of the Republic of Switzerland, residing at Lucerne, Switzerland, have invented certain new and useful Improvements in Apparatus for Carbureting Gas by the Vapor of Liquid, of which the following is a specification.

This invention relates to an apparatus for carbureting gas with the vapor of an appropriate liquid, particularly applicable to the manufacture of air-gas-that is to say, of a combustible mixture made by pressing air over a porous mass saturated with gasolene or the like. As is known, such a mixture may be used as a substitute for coal-gas.

The essence of the invention resides in the fact that the supply of gasolene is automatically regulated to correspond with the consumption of the gas. The compressed air necessary for working the apparatus is derived either from a holder or from au appropriate blower', which may be set in action at the beginning of the gas consumption and supplies a current of air to the carbureter. In the latter case the whole working may be automatic.

By way of example there is shown in elevation, partly in section, in the accompanying drawing an apparatus constructed according to this invention.

The carbureter a is in this instance counterbalanced on an ordinary weigh-bridge.

The counterweight mechanism is shown to be composed of a platform S10, supported near one end upon the knife-edge S8 of a lever s', which is in turn supported upon knife-edge S11. The platform and lever are respectively connected by rods S2 s3 with the scale-beam,

partition e, which, however, extends only across the interior of the porous cylinder. The air enters into the interior of the lower compartment of the cylinder through the pipe fand passes through the porous wall into the space between the sheath and the cylinder, and thence it again passes through the porous wall into the upper compartment and finally flows out through a pipe g. The connection of the pipes f and g with the fixed parts of the pipe which conducts the air to the apparatus and that which leads away the gas, respectively, are made telescopic with liquid seals 7L 'L' in order to allow free movement of the carbureter. The seal t is connected to post A by arm t" and collar 112. A draw-O cock i3 serves to remove any possible accumulation of liquid from the gas-discharge pipe t4. The seal h has the air-pipe h2 and is connected to the vertical post A by arm t'* and collar h5. A small coil h4, having cock hlserves to discharge any possible accumulation of gasolene from the carbureter. The two parts of the carbureter-sheath are also connected by a liquid seal d'.

Vertically above the carbureter is supported a gasolene-tank k, adapted to be filled through Siphon-tube 7.06 and of a capacity sufficient for, say, a twodays supply. The tank 7c is connected to post A by arm 7c' and collar 7a2. The arm k is, by brace 7c3 and bent arm 7a4, connected to a second collar h5 of post A, so that any vertical displacement of tank 7.o is prevented. At the bottom of the tank is a pipe l, closed at its upper end by a valve m and opening at its lower end in a vessel n, supported on the carbureter. The connection between the pipe 'Z and this vessel is a water seal. The valve m is attached to a wire or rod m', which at a certain height of the carbureter bears at its lower end on the bottom of the vessel n. This vessel is, through pipe g, connected to carbnreter d, and thus rises and falls together with the same. A bent Siphon-tube o leads the gasolene from the vessel 'a to the carbureter. The height of the column of liquid which remains in this Siphon-tube o is so chosen that a pressure in the carbureter will not cause gas to flow by way of the vessel n. From the tube o the gasolene Hows into a gutter ot on the conical cover of the carburetor-cylinder b, which gut- IOO if. La'

ter, as well as the cover, is coated with porthence is uniformly distributed over the whole surface of the cylinder-a result which is aided by the packing between the rings of which the cylinder is composed.

The tank 7c is closed above and is in cornmunication with a bag p, which receives the y -part of the gasolene the carbureter becomes gas or vapor expelled when the tank 'is filled. The filling is effected through a stop-cock funnel froina vessel q, also provided with a cock g3 and which discharges the gasolene into tank It through tube k6. The vessel q is connected to post A by arm q/ and collar q2. The cover of the tank 7c also carries a glass tube r, in which is the end of a wire m2, carried by the valve m, the position of this end y in the tube serving to indicate the position 2 A float with an indicator, also extending into the glass tube, shows the level 1 of the valve.

of the liquid in the tank it. `The vessel n is provided at its lower part with a draw-offl` cock s.

The apparatus works as follows: The tank k is rst filled with gasolene. There being no weights on the counterbalancing-pan of the weigh-bridge, the carbureter is in its lowest position and the valve-rod m is out of;

ows the gutter and passes over the porous i material which covers the conical cover of the carbureter. At the edge of the cover it falls in drops into the gutter a2 of the upper- -1 most ring b and descends gradually through the pores of such rings, while the rings c Will By placing weights on ihe scale-pan the carbureter is raised and the valve m is lifted to a certain i cause a uniform distribution of the liquid. In this Way the weight of the porous cylinder is increased, so that the carbureter sinks and the valve m closes. By proper adjustment of the weights the amount of gasolene admitted may be regulated to the proper proportion for the air. If it is undesirable that the whole of the gasolene should enter the carbureter, a portion can be drawn off from the vessel n by the cock S. As the air passes through the carbureter and carries away a lighter and is raised until it opens the valve and admits more gasolene. While gas is being produced the apparatus and weights should be in equilibrium, which may be observed on the indicator of the weigh-bridge.

The degree of carb u reting may be varied i-n this apparatus accordingly as illuminating or heating gas is required.

I claim- 1. In a carbureting apparatus, the combination of a counterbalanced porous gasilier, with an air-inlet pipe, agas-delivery pipe, and a gasolene-tank communicating therewith, and with a valve between the gasolene-tank and the gasiiier which is automatically set by the latter, substantially specified.

2. In a carbureting apparatus, a gasifier composed of a series of porous rings, intervening porous packings,a su rroundingjacket, and a partition, combined with an air-inlet pipe entering the lower section of the gasifier, a gas-delivery pipe entering the upper section of the gasiiier, a gasolene-tank communicating with the upper section of the gasifier, an intervening valve which is automatically set by the latter, and means for counterbalancing the gasifier, substantially as specified.

In witness whereof l have hereunto signed my naine in the presence of two subscribing witnesses.

FRANZKELLER KURZ.
