Application filed February 15I To all whom, zit may concern:

Be it known that we, FRED S. JAOKS and .WILLIAM D. JACKS, citizens of the United- States, residingin the city and county of San Francisco, State of California, have invented an Improvement in Carburetors; and we hereby declare the following to be a full, clear, and exact description of the same.

Our invention relates to an apparatus which is designed for the manufacture of gas from hydrocarbon or like liquids from which the inflammable gas or. vapor can be produced.

It consists of the parts and the constructions and combinations of parts,which we will hereinafter describe and claim. I

Figure 1 is an elevation of the machine, parts shown in section. Fig. 2 is a vertical section through the valves controlling the flow of wa ter. Fig. 3 is adetail of the generator and its connections.

As shown in the present drawings, A is a gasometer-bell adapted. to rise and'fall ina tank B, containing Water, in which the lower which forms a seal in which the. bell A' rises and falls as the gas is increased or diminished within'it. 1

2 is a pump, which donsists of a hollow eylend, said cylinder being adapted to rise and fall within a tank 3, its lower end being submerged beneaththe.watercontained in the tank 3. 'In line beneath the center of thetank 8 is a hollow cylinder 4, in which a plunger 5 extending above the fits, and the plunger-rod 6 extends from the plunger or pistono up through a tubular-connection 10 with the bottom of the cylinder 3, and its upper end is connected with the top of the bell 2, so that when the piston is forced up by pressure it raises the hell 2, and when allowed to fall the bell willsink by gravitation. vBy means of a suction-pipe 7, to be here after described, air and gas are drawn into the hell 2 from the carbureter 8, with which the pipe connects, and ,when the bell sinks the gas is forced out through the same pipe into the 'carbureter, and thence through a conducting-pipe 9 into the gasometer-bell A. A tube 10 surrounds the plunger-rod 6, this tube surface of the Water in the tank 3, and a second tube 11 of larger di- 1'901. SeflalNo- ILMO. (No model.) V

ameter has its upper end fixed to the top of the bell 2 and extends down over the tube 10,

caping around the plungerrod. Parallel with and adjacent to the cylinder 4 is an air-pump cylinder 12, having within it a plunger 13,

and the rod .14 is connected by a cross arm or .FR'ED soAoKs AND WILLIAM D. JAoKs, on SAN FR Norseo, CALIFORNIA;

forming-a seal or lockto prevent any gas esbar'with a rod 15, which extends up'through I the tank 3 and is connected with the top of the tank in a similar manner to the rod 6. It also has similar inclosing tubes 10 and 11 toaetasagzeal...

Water under pressure is admitted into the lower part of the hydraulic cylinder 4 through a pipe 16, and the water is admitted and exhausted' by means ofvalves 17 and 18, which i are connected by their stems 19.with an (30- centric 20,1which is rotatable and operates so that when one valve is opened the other is closed. One of these valves,-as 17, controls the inlet through a pipe 21 from-any source of supply. The other, as 1:8,controls the outlet through a' pipe, as at 22. These valves are situated one upon each sideof a central opening in the valve-chamber,which connects with the supply-pipe-lti, leading to the -cy'lin der 4,'as previously described; J

23 is an air-chamber to steady the pressure and relieve the shock of water as it enters and leaves.

The shaft 20. of the eccentric 20 extends out through one end of the central portion or,

'the device containing the eccentric 20 and has upon it the loosely-turnable arms 24 25. The arm 25 is connected by chains 26 with the rod 15, one of these chains extending up-"- vwardly above the center line of the shaft and -the other downwardly. v I r The operation will then be as follows: If the piston or plunger 5 is at the bottom of its cylinder 4,- the inlet-valve 17 will beopened and the outlet-valve 18 closed by the turning of the eccentric sufficient to produce these results. The water under pressure passing through the admission-pipe 21,thence through the passage in the upper part of the valvechamber, and thence out through the pipe 16 enters the bottom of the cylinder 4 and forces the plunger 5 upwardly. This acts through its rod 6 to lift the hell 2 and produce a vaeuum within it above the water. The vacuum.

thus produced continues through the pipe 7 and into the carbureter 8, andthis draws the liquid from the measuring-tank 27, through a passage 28, into the carbureter-chamber8, at the same time an air-inlet valve at 29 is opened, so that a suitable proportion of air may pass in through this valve and into the carbureter. The upward movement of the bell acts upon the rod 15,.thus forcing theweight'upon it, will have passed the center.

As these arms turn loosely upon the shaft they will not act to move the shaft or to change the position of the valves 17 and 18 until the weighted arm 24 falls and strikes one of the pins 33,which project from the eccentric-shaft. The weight striking this pin will then suddenly turn the eccentric and reverse the position of the valves, closing the valve 17 and opening the valve 18. t This shuts off a supply of water through the pipe 21 and opens a discharge from the pipe 16 through the pipe 22.

" 'then causes the'plunger 5 to sink and with it The weight of the hell 2 or any additional weight which may be placed-upon it the bell. The water in the cylinder4 will be forced out through the dischargepipes, as before described, and the gas which has been drawn throu'gh the pipe 7 by the upward movement of the-bell 2 will now be forced back through-the carbu reter8, thence through the pipe 9-, and into the gasometer-bell A.

Each reciprocation of the parts of the appa-' ratus will produce a s'imilar action, and the amount of gas itrthe gasometer will be renewed at each operation.

The pipe 28, leading from the measuringtank 27, extends up into the tank to a point which is above the level of the liquid'therein, and its upper end is open. Asecond pipe 34, closed at the upper end and of larger di ameter, fits down over this pipe 28, extending to near the bottom of the tank, and this forms a passage between the two, so that any pressure upon the surface of the liquid caused by direct pressure or by vacuum through the carbureter willcause the liquid to flow up in the pipes 28 and 34, and thence down through 28 to the point of discharge. The pipe 34 may be raised or lowered by means of a screw 35, connecting with its upper end and turnable in a suitable threaded nut, as shown. Thus the discharge end or the pipe 34 may be raised or lowered with relation to the bottom of the measuring-tank. A check-valve is connected with the measuring-chamber through a at 40, and thisiserves to regulate the pressure of air within t tank 31.

41 is a check-valve in the pipe 30 to prevent the return of air-when the pressure through the pipe 30 is reduced. This checkvalve may be similar to the valves above de scribed or of any suitable or well-known character, and a similar valve is connected with the air-inlet pipe 29, as shown.

An overflow-pipe is located at 42', contiguous to the tanks B and 3, and 'a pipe 43 con-. nects the tanks B and 3, and. through this the water isallowcd to pass from one chattiber to the other in case the water rises higher in either one than'the other. Drain-cocks are connected with the waste-pipe, as shown at 44, for the removal of surplus water from the tanks or the overflow 42.

Any suitable or well-known form of car bureter may be employed. In the present arrangementwe have shown acarbureter as having spirally-disposed-plates 46 in the form of a coil or coils extending between the top and bottom of the carbureter-chamber, and in the space between these coils are loosely wound ropes or equivalent masses of fibrous absorbent material 47 The inlet-pipe may deliver into the outer part of the coil, as shown, and the outlet-pipe discharge from the center, so that the air drawn through the hydrocarbon in the carburetenis continually brought into contact therewith and fully saturated in passing through. The supply of water for the tank 3 is kept up,by such. leakage as passes the piston 5 of the cylinder 4, and as the tube 10 connects with the top of the cylinder this water will be delivered from its upper end into the tank. The pipe 43 will convey water from 3 to B and keep B supplied, and the surplus willdischarge through the overflow-pipe 42. Both-g'asometer and 1e pipe 30 and in the gasolenepump-bellsA and 2 are guided in their rise v and fall by vertical central rods or equivalent tubes, as at tier 6. gasolene or equivalent hydrocarbon through the carbureter and its vaporization cause such a reduction of temperature that freezing and stoppage will take place unless there is some means to prevent it. This means is provided in our device by the tank 3, containing a large body-of water which raises the temperature of the vapor or gas which is drawn through it by the upward movement of the bell 2, and when this gas is forced through the carbureter and into the gasome- The passage of the ter by the downward movement of the hell 2 its slower movement and contact with the waterand the slight compression will prevent its becoming detrimentallycoldz' The measuring-tank has within it a float 27, and a tube 27" extends upwardly from the Heat, open at the top and closed at the bottom. This tube contains mercury, and the end of the fixed conducting-pipe 32 extendsinto the tube 27. hen the floathasrise'n so that the mouth of the tube is submerged in the mercury, further supply to the measuringtank and carbureter is cut off, and when the the siphon-pipes 28-and 351, as previously de:

\ 48 is a vacuum relief-valve connecting with tank 27 to admit air as the liquid flows out to the carbureten' When the How of gasolene through'the pipe I 32 from the reservoir 31 is stopped by the mercury seal above described, the pressure in the reservoir througlnthe ainpipe 30 is regue lated by a relief-valve at 40.
