GAS-MACHINE.

SPECIFICATION forming part of Letters Patent No. 253,028, dated January 31, 1882.

Application filed April 14, 1881.

To all Awhom it may concern Be it known that we, REEsE W. FLOWER, Jr., and EDWARD C. BURGEss, both citizens ot' the United States, and residents ofthe city and county of Philadelphia, and State of Pen nsylvania, have invented a new and useful Improvementin Gas-Machines, which improvementis fully set forth in the. following specicntion and accompanying drawings, in which- Figure 1 isa side elevation, partly sectional, of the gas-machine embodying our invention. Figs. 2 and 3 are views of detached portions thereof.

Similar letters of reference indicate corresponding parts in the several figures.

Ourinvention consists oi' a valve which opens at the proper time to permit the exhaust or' the generator.

It also consists of novel means for operating the supply-pump of the generator.

It also consists of means for preventing the forming of an air-cushion and a vacuum in the generator.

It also consists cfa pipe communicating with the air-chest of an air-pump and the exhaustpipe ofthe generator, whereby air is continuously intermixed with' the vapor, and the gas thus forced to the place ot' service.

Referringr to the drawings, A represents the vaporiZin'g-chambcr or gas-generator, which is ofthe form ot' a tube or cylinder supported upright on the frame B of the machine, and surrounded by a water-jacket, C.

Within the generator A is a piunger or piston, D, the stem E of which has connected to its upper end the piston F ot' an air-pump, G, which is properly mounted on a platform supported on the standards B' of the frame B.

Communicating with the air-chest G' ofthe pump G is an air-conveying' pipe, H, with which latter also communicates a pipe, J, leading from the interior ofthe generator A.

Attached to the stem E, outside ot' the generator, is a collar, K, which is provided with an arm, K', havin ga boss or sleeve, K", through which passes loosely the stem L of avalve, M, the shell of which rises from the base of the generatorA or the frame B and communicates with the pipe J, said stem L having secured to (No modell it stop-collars L', one of which is located at the upper end of the stem and the other between the ends of the stem, so that there is a collar above and below the boss K" ofthe arm K'.

N represents a pipe, which forms a communication between a pump, P, and the base ot' the generator A, said pump being properly located and supported and leading from a tank or other place ot supply of hydrocarbon or other proper fluid or oil.

The pump-rod Q has connected to its upper end acord or chain, R, which passes around a grooved wheel or pulley, S, and carries at the end opposite to the connection with the pumprod a weight, T. The pulley S is suitably suspended or supported by means ofayoke or other bearing, U, connected to the top platform or one ofthe standards B', and has Secured to one facea segmental ratchet,V,with which is adapted to engage a pawl, W, pivoted to the yokeU. An upright rod or pin,X, is passed through a horizont al eye, X', projecting from the yoke U, below the pawl W, and so disposed that when elevated it may strike said pawl from below and raise it clear ofthe ratchet Y, said pin bc-l ing pivoted to one end of a lever, Y, which has its axis on the yoke U, its other end being secured to the collar K of the stem E by means of a slotted connection, as at a, said lever Y being adapted when raised to strike the ratchet V.

The water-jacket C surrounds the sides and base ofthe generator A, the bottom or portion of said jacket below the base of the generator being shown at C'; and below said bottom C' is located the heating device Z, consisting in the present case of a series ot gas-jets arranged in annular form.

The operation is as follows: The gas-jets are lighted, so that the water in the jacket is heated, thus heating the generator A. To start the machine the pump P may be operated by hand to inject a supply of fluid or oil into the generator. The oil is immediately' converted into vapor, the impulse of which elevates the piston D. As the stem E rises it lifts the lever Y and arm K'. The lever Y comes in contact with the ratchet V and rotates the pulley S, and the end of said lever, carrying the pin X,

descends, thus lowering said pin and permitting the pawl l to drop on the ratchet, which latter rides f'reely past the pawl until the lever has reached its highest point. The sleeve K", ascending with the arm K', strikes the upper stop-collar, L', and raises the plug or piston of the valve M. The vapor in the generator now enters the pipe H, where itjoins a volume of air forced into said pipe H by the action ofthe ascending piston F of the air-pump G, and thus the gas is forced to the place of service. The rotation of the pulley S by the action of the lever Y, as has been stated, lowers the chain on the side connected to the pump-rod, and the latter descends as one motion of said pump. The weight ofthe piston F of the airpump now causes the descent of the stem E and piston D of the generator, and as the lever Y leaves the ratchet V the pawl NV engages with the ratchet-in the present case the right-hand toothand prevents rotation of the pulley S. The descent of the stein E brings the sleeve l agaiustrthe lower stop-collar, L', thus closing the valve M, any remaining vapor in the generator heingforced outinto the pipe J by the descending piston D `just in advance of the closing of the valve. As the stem E 'descends it lowers the lever Y and gradually raises the pin X,which latter at the proper moment disengages the pawl WV from the ratchet V, whereby the weight T becomes operative and causes the rotation of the pulley S, so as to raise the pump-rod Q as another motion of the pump, and immediately a supply of oil is ejected or forced into the generator, where it is vaporized, and the succeeding operations are similar to those hereinbefore stated.

The base of the generator is widened or flaring and grooved on the upper face of its bottom plate, whereby a large heating and vaporizingsurfaee is obtained, andthe water-jacket conforms tothe shape of the base,so that every important part ot' the generator is heated.

rlhe pump Gr is double-acting, two of its valves opening from the atmosphere and two opening into the air-chest G', so that on hoth the ascent and descent of the piston F air is forced into the chest, and thus continuously directed into the pipe H, where it joins the vapor from the pipe J, and so the gas passes uniformly to the place of service.

The stem E of the pistons D F is hollow and perforated, so that it communicates with the generator A and barrel or cylinder of the airpump, respectively, above and below said pistons. Should there be air in the generator above its piston D, when the latter ascends the air is caused to enter the hollow stem E,

and so reaches the barrel of the pump, overcoming the formation of an air-cushion in the generator, whereby the ascent of the piston D is not retarded. When the pistons are ready to descend, the air may again enter the stem E and reach the generator through the hollow stem, thus preventing the formation of a vacuum in said generator, or relieving the latter of such, it' formed. The stem E is common to both pistons D F, and the construction and location of all parts are such that the machine is simple and compact in its nature.

The water-jacket has an inlet, b, for replenishingit with water, and an opening, c, for escape ot' steam.

Te are aware that it is not broadly new to surround a gas-generator with a water-jacket which applies hot water to the enlarged bottom and to the sides of said generator; also, that it is not broadly new to employ levers, rods, chains, pawls, and weights, in combination with the piston-rod of a generator and the source of supply of.' said genera-tor for governing the supply of gasoline; and that itis not new to utilize the hollow rod ot' a pumppiston for the passage of gas from a generator below the pump. We do not claim any of such constructions. Y

That we do claim is- 1. The generator A,in combination with the valve M and pipe J, and the connected piston-rod E and valve-stein L, substantially as and for the purpose set forth.

2. rlhe generator with its piston-rod and a connected arm, in combination with the pump mechanism consisting ofthe pump-rod, chain, pulley, pawl and ratchet, and weight, said weight operating reversely to said piston-rod of the generator in turning said pulley, substantially as and for the purpose set forth.

3. The pulley,pump-rod,and weight,incom bination with the ratchet V, pawl W, risingand-falling pin X, and mechanism for operating said pin, substantially as and for the purpose set forth.

4. The generator and air-pump,in combination with a communicating hollow piston-rod, substantially as and for the purpose set forth.

5. The gas-generator and an air-pump, in combination with a pipe communicating with the air-chest of said pump and the exhaust or discharge pipe of the generator, substantially as and for the purpose set forth.
