IMPROVEMENT IN AlRAND GAS CARBURETERS. J I

Specification fol-mini: out

To all whom itmay. concern:

Be itknown that we, A oNzo W. Bonnie and ,FRANOIS. M." GRIMES, of New York, in the county of New York-and State of new York, have invented a new and valuable Improvelnent in- Air and Gas Garbureters ant we'do horebydeclare that the following isa full, clear, and exact description of the constructi n-and operation of the same, reference being bad to the anneied drawings, making a .part of this specificatiomand to th evlett'ers and figures of reference marked thereon.

Figure 1 of the drawings is' a representation of a front-tiew,;part sectional, of-'our. carbureter. Jiig. '2' is a verticalsectional view of the same, and Fig. 3 is aplan. view containing gasoline, in one compartment of which floats. the hollow vessel which actuates the valve in the feed-chamber, as will be hereinafterzexplained. The invention finally consists inan automatic regulator of the heat, which we design ate ahydro-therm'ostat, which is applied to the gasifyingchamber or chambers, for the purpose ofi Inaintainingthe proper vaporizingtemperature in these chambers, as will be hereinafter explained.

In th" annexed drawings, A "designatesia rectangular boxof any suitable capacityf which is dividedby a partition, a, into twocompartments, b b, communicating with each other "by means of openings through the bottom of the partition a. B is the supply-pipe for the gasoline," which pipe leads from an ele- Yatedreservoirof this fluid into the compartment b, terminating therein in a valve-box, O, outof which leads verticallya discharge-pipe, B. The stem of thevalve in the box (-1 has an arm, 0,.keyed Quit, the free end of which is of Letters Patent No. 168,048, dated September 21; 1975; reissue No. 6,865, dated January 18, 1676; application fi led December 14, 1875.

a pipe, D and has a float, D, secured to its lower end. The float D is vertically movable and-fall of the float D the valve in the box is actu'ated,'and the flow of the fluid into chain" ber b is regulated or cut 0d. The pipe D rises in chamber 1) several inches, or at least high enough to preygent the gasoline therein from'flowingover it. Inthe chamber 1) there is-afdiyision-plate, b, rising a'few inches for allowing the gasoline to collect in the chamber 1) and to flow over-into the discharging portion of the chamber b From thecha mber b the gasoline flows in a thin broad sheet forward conduit, G, which folds are corrugated, as shown in.F-ig's 1 and 2. The object of corru- 'gatin-gflonwaving the folds'ot the conduitis toface. By this means the volatilization of the tions also give undulating motion to the flowin liquid. From the conduit G the gasoline flows into the first one of a series of chambers, J,-"which are separated by. partitions c', open alternately at their ends for the purpose of causing air or gas introduced through a end to the other of everyone of said chain hers J over the gasoline therein. After leaving the last one .of the series of chambers the air or gas circulates through the conduit G,- 'where; it takes up the vapor of hydrocarbon and becomes highly enriched. From the highest one of the folds of the conduit G the enriched .gas' enters chamber 1), from which it is drawn off for use through a pipe, K.

The apparatus above described is arranged inside of a tank, L, which is designed for con-- taining water, andwhich may extend up any desired height. In the bottom of the tank L are two sinks, f g, which. communicate with" an annular box-,N, byineans of'pipes f. and g. The-pipe g allows'water to pass from the ter when being heated. In an offset of the pivoted to a rod, D, thatpasses freely through i tank L we arrange a shallow vessel, M, which i-nfthegasoline in achamber, E. By the rise and backward through a number of folds of a obtain a very'large amount of surface in a comparatively sinall space, andgto cause the fluid to spread itself evenly over its entire surfluid is greatly accelerated'. The corruga pipe, H, to circulate back and forth from. one

tank into the box N, and from the latter, when heated, through pipe f, back into the tank, thus keeping up acirculation of the waother. The pipe 1" comi'ninlicatcs with the pipe K by means of a pipe, K, and from the upper end of pipc'l? a small pipe, It, is carried downward and beneath the box N, for the purpose of furnishing a small taper flame to a circular burner, S. This circular burner S is arranged directly beneath the box N, and, when lighted, will heat the water in this box and maintain a proper temperature of the mercury below. the boiling-point of gasoline forthe operation of the h yd ro-thermostat. The circular burner S is supplied with gas from a pipe. 7), leading from the upper end of the pipe P. When the liquid in the tank L reaches a temperature of 20 Fahrenheit the mercury in thcwesscl M will rise and cut oti' the supply of gas to the burner S, thus putting out the flame and allowing the temperature of the fluid in said tank to fall. The mercury in the vessel M will descend and open a. con'nnunication again for the supply of gas to the burner S, which will be ignited by the taper kept constantly burning in close relation to the burner S. By these means, which we designate a hydro-thermostat, the proper temperature of the fluid in the tank ismaiutained at all times.

We have represented a valve formed of mercury, which, by its expansion and contraction, will close or open the communication automatically actuated by the heat of the space sur rounding it. The pipe .T, which extends to the bottom of the float-chamber, will have a pump attached to it, for the purpose of removin g water or anyheavyresiduum which may accumulate in said chamber.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-- 1. A vaporizing-conduit, Gr, formed of hollow corrugated folds, substantially as described. y 2. A carbureting-chamber, having the passages J and partitions e, combined with the conduit G and the chamber E, containing a float, D substantially as described.

3. In a carbureting apparatus, the tank L, sinksfg, pipes f g, heater N, burner S, and its taper, in combination with the mercuryvessel M and pipes P I? K K, substantially as described.

4:. In an air or gas carbureting machine a' broad horizontal corrugated vaporizing fold or conduit with intermediate spaces between the folds combined with an automatic feeding device, substantially as described.

5. The combination, with a machine forearbure'ting air or enriching gas, of a hydrothermostat which automatically regulz-ttesthe tem-' perature of the fluid hydrocarbon below the boiling-point of gasoline, substantially as and for the purpose set forth.

6. The combination, with a heater, of a carbureter set in a water-tank in which is a mercuryalve, actuated by the heat of the water,

the temperature of which it controls and maintains at any point below boiling.

In testimony that we claim the above we have hereunto subscribed our names in the presence of two witnesses.
