Application filed F br ar 11, 1897. Serial No. 622,915. (No model.)

To all whom it may concern:

Be it known that we, FRANK E. STANLEY and FREELAN O. STANLEY, of Newton, county of Middlesex, State of Massachusetts, have invented an Improvement in Gas-Machines, of which the following description, in connection with the accompanying drawings, is a specification, like letters and figures on the drawings representing like parts.

This invention has for its object to improve the construction of gas-machines wherein naphtha or some other equivalent hydrocarbon liquid is converted into a gas for illuminat in g and other purposes, such a gas being commonly known as air-gas.

In accordance with this invention an airpressure device is employed for delivering air to the carbureter, and a delivering device is employed for delivering hydrocarbon liquid to said carbureter, and means are provided for operating said air-pressure and liquid-delivering devices conjunctively to store up a supply of air and hydrocarbon liquid, and said devices also operate conjunctively. to simnltaneously deliver the stored-up air and liquid in uniform proportions to the carburotor.

The quantities of airand hydrocarbon liquid stored up at each conjunctive operation of the air-pressure and liquid-delivering devices are proportionate to the quantities required in producing a certain quantity of gas of the desired quality, and as said devices operate con j unctively they will also deliver their respective stored-up supplies to the carbureter in uniform proportions.

The action of the delivering device is made absolutely dependent upon the action of the air-pressure device, and to accomplish this result the delivering device is constructed and arranged to be operated directly by the airpressure device instead of by the motive power or means which is employed to operate said air-pressure device, and, as herein shown, the said delivering device is operated directly by the air-pressure device to first store up a measured quantity of hydrocarbon liquid and is thereafter operated by said air-pressure device to deliver its stored-up supply to the carbureter. Our invention, however, is intended to include the important feature of operating the delivering device directly by the air-pressure device and utilizing the motive power solely for operating the air-pressure device, even in case a supply of hydrocarbon liquid should not be stored up at each operation.

The air-pressure device comprises, essentially, a gravitating air-receiver, and means are provided for raising it to store up a meas- 6o ured quantity of air which will be subsequently delivered to the carburetor, and said gravitating air-receiver is herein shown as connected with the operating member of the delivering device, so that as said air-receiver is raised to store up a quantity of air the delivering device will be operated at the same time to store up a proportionate quantity of hydrocarbon liquid, and as said air-receiver falls by gravity to deliver its stored-up sup- 7o ply of air to the carbureter the delivering device Will be operated at the same time to deliver its stored-up supply of hydrocarbon liquid to the carbureter, the action of the delivering device being thus absolutely depend- 7 5 cut upon the action of the air-pressure device.

As herein shown, the hydrocarbon liquid is expelled from the delivering device by displacement that is to say, the delivering device may consist of a receptacle which contains a supply of hydrocarbon liquid, and a body--such, for instance, as a hollow vessel, tube, or rodis adapted to be moved up and down in said receptacle and when descending to expel the hydrocarbon liquid by displacement.

As a means of supplying the delivering device with hydrocarbon liquid a supply-tank is provided, Which maybe located at any suitable or convenient place and which will contain a large supply of hydrocarbon liquid, and as herein shown a stand-pipe rises from said supply-pipe which is connected with said delivering device, a valve being employed to control the passage from said stand-pipe to 5 said delivering device. The hydrocarbon liquid is maintained in said stand-pipe at a predetermined elevation, so that whenever the controlling-valve is opened a measured quantity will flow from the stand-pipe into the delivering device to be subsequently (lelivered to the carburetor. The liquid is caused to rise in said stand-pipe by means controlled and operated automatically in order that the stand-pipe will be filled at all times sulliciently to supply the delivering device with a measured or predetermined quantity.

Many of the parts herein to be described are novel and are included in this invention, as well as connections whereby certain con- ;i unctive and automatic actions are produced, as will be hereinafter more fully specified.

Figure 1 shows in side elevation a gas-machine embodying this invention; Fig. 2, a side elevation of the actuating device for the air-pressure device; Fig. 3, a detail of the means employed for maintaining hydrocarbon liquid in the stand -pipe at a certain level; Fig. 4:, a detail to be referred to; Fig. 5, a side elevation of a portion of the gas-machine shown in Fig. 1; Fig. 6, a vertical section of the delivering device by which the hydrocarbon liquid is delivered to the carbureter; Fig. 7, a detail showing the indicator by which the operation of the machine may be observed; and Fig. 8, a vertical section of the valve which forms the essential element of the actuating device, which is solely connected with and adapted to operate the airpressure device.

The air is supplied or delivered to a carbureter or converter 0 by means of an air-pressure device, which consists of a tank or hollow cylinder a, nearly filled with water and open at the top, and a hollow air-receiving cylinder 1), open at the bottom only and made smaller in diameter than the cylinder at and suitably suspended or supported above said cylinder at and adapted to rise and fall within said cylinder a, thus working substantially on the principle of an ordinary gasometen;

It is designed and intended that the operation of said air-pressure device to store up and to deliver air to the carbureter shall be carried on without attention or action on the part of the user, and also that the actuating device jecting upwardly from its closed top wall, and

said rod 1) has attached to or mounted upon its upper end a plunger or piston a, which is adapted to fit tightly and work up and down within a cylinder D which may be held in an upright or vertical position by a suitable frame or support L to which it is attached. A pipe '0' leads from the valve u to said cylinder b entering it at a point below the piston a, and the water is forced through the pipe The air-receiving cylinder or air-receiver Z2 has a rod 1) fixed to and pro 01' into said cylinder b moving the piston or plunger a upward, and thereby bodily 1ift ing the air-receiver b. As the air-receiver Z) is thus raised the air is admitted and stored up for subsequent delivery to the carbureter as said receiver Z2 falls by gravity. Thus the air-pressure device is operated to store up air by water admitted under pressure, and operates to expel or deliver said air by the falling of its gravitating air-receiver b. The valve 1), Fig. 8, which controls the admission of water under pressure to said cylinder 17*, c011- sists of two cylinders o '0 located side by side and connected by a short pipe W. The cylinder '1) has a chamber 41 within it, provided with an inlet-port 'v for the inlet of the water, and an inlet-pipe o is connected with said cylinder 41 at such point. At the bottom of said chamber 4: a valve-seat o is located, which when open allows the water entering the chamber c to pass through it into the chamber 219 below said valve-seat and then into the pipe 1). A valve 12 is contained in the chamber 0 which is attached to a rod i2 passing'out through the upper end of the cylinder c and said valve is adapted to close on said valve-seat o to shut off the supply of water, preventing the water from entering the pipe 7). It will be seen that when said valve 11 is raised, as shown in Fig. 8, the water is free to enter the chamber and flow into the pipe 41, and when said valve is seated the water is shut off. The cylinder t has a chamber 12 within it and has also a valve-seat i1 and a valve 12 is adapted to close on said seat which is attached to a rod c", which passes out through the upper end of the cylinder c Above the valve-seat v another chamber 41 is provided, having an outletport r ",to which an outletpipe c is connected. The short pipe 11 connecting the two cylinders '0 is in open communication with the chambers 229 and 12 The two valve-rods r and r are connected together by a cross-head 01 so that the two valves will be simultaneonsly operated. It will be seen that as the valve c is raised, and thereby removed from its seat, the valve o will be closed on its seat, and with the parts in such position, as shown in Fig. 8, the water is free to enter and flow into the pipe '0 for the purpose of raising the air-receiver b, and as soon as said valves are operated in the opposite way, the valve n closing upon its seat and the valve 11 leaving its.seat, the supply of water will be shut off and an open passage provided from the pipe 4; through the chamber u", pipe 21 chambers r and o, and through the outlet-port v to the outlet-pipe c. The crosshead 11 of the valve 11, which controls the admission of water under pressure to said cylinder W, is connected to a plate 1), (see Fig. 2,) which is pivoted at m to the frame and as said plate is turned on its pivot in one or the other direction the valve 4) will be opened and closed. To turn said plate rom its pivot in one or the other direction to thereby con- ITO trol the action of the valve o, and thus control the admission of water, the arm m is pivoted at m and provided at its outer end with a weight w, and said arm is adapted to occupy two different positions, one, as shown in full lines, Fig. 2, wherein said arm rests upon a pin 19, projecting laterally from the plate 19, and the other, as shown by dotted lines, wherein said arm rests upon the pin m projecting laterally from said plate 19, and as the pivot m is between said pins it will be seen that the plate will be turned in one or the other direction by the to-and-fro movement of the arm m. l/Vhen the arm m is in the full-line position shown, resting upon the pin p,the plate 19 is turned to close the valve 0), and when said arm is moved into the dottedline position shown said plate 10 will be turned to open said valve Q). To automatically control the valve '0 by means of the airpressure device a b, we provide mechanism whereby said actuating-arm m Will be operated by the rising-and-falling air-receiver b. An arm m is provided for operating the arm m, it being pivoted at m in front of the plate 19, and the arm m has a pin m projecting from itlaterally at a point near its pivot m against which the lower end m of said arm m bears when said arm m is in the full-line position shown in Fig. 2. As said arm m is depressed or caused to occupy the dotted-line position shown, its lower end m by engaging the pin on" will positively raise said arm m to a vertical position and cause it to pass the center, when said arm on will fall by gravity into its dotted-line position, and as said arm m is raised or caused to occupy its fullline position it will engage said pin m on the arm m, but at the opposite side of its pivot, and will move said arm m into a vertical position and cause it to pass the center, when it will fall by gravity into the full-line position shown. Thus by depressing said arm m the arm m will be caused to move from its full to its dotted line position and in so doing will rock the plate 1) and open the valve 7:, and by raising said arm the arm m will be caused to return to its full-line position, and in so doing will return the plate 1) and close the valve o. To thus depress and elevate the arm m to operate the arm m, it is made long enough to enter and work between or cooperate with two nuts m m, adj ustably located upon and at the upper part of the rod m which is fixed to and projects upwardly from the top wall of the gravitatin g air-receiver b, and as said airreceiver falls the uppermost nut on will engage said arm m and depress it a certain distance, sufficient to raise the arm m and cause it to pass its center in order that it may fall into the dotted-line'position shown by gravity, and when said arm m thus falls its pin m will strike the arm m at the opposite side of its pivot and will further depress said arm m and as said air-receiver rises the lowermost nut in will engage said arm m and elevate ita certain distance, sufficient to raise the arm m from its dotted-line position into a vertical position and cause it to pass the center in order that it may fall into the full-line position shown by gravity, and when said arm m thus falls its pin hi will strike the arm m at the opposite side of its pivot and further elevate said arm on, causing it to bear against the uppermost nut m Thus it will be seen that when the valve is open the water under pressure will be admitted to elevate the air-receiver b of the air-pressure device and that when said air-receiver h rises to a certain elevation the said valve 1* will be closed and will remain closed while said air-receiver falls to expel the air and deliver it to the carbureter,and when the falling air-receiver reaches a certain point it will operate to open said valve 1; to again admit the water. It will thus be seen that the air-pressure device is automatically actuated to store up air to be thereafter delivered to the carbureter and that its actuator is in turn controlled by the air-receiver b of said air-pressure device.

The valve 72, through which air is admitted to the air-pressure device, consists of an airtight box n, partly filled with a liquid, a pipe M, which passes down through the top wall of said box and extends down into the liquid and terminates some distance below its level, and a pipe at, which leads from the top wall of said box n. The pipe n extends to and connects with a T-coupling 30, located beneath the tank a, and a pipe 31 extends from said T-coupling 30 up through the bottom of said tank a and through the liquid contained therein and terminates at a point above the level of said liquid. A check-valve of any wellknown or suitable construction (not shown) will be contained in the pipe 11 to prevent back pressure of the air. As the airreceiver 7) rises a partial vacuum is produced within it, and air is drawn in through the pipe n and through the liquid in the box '17., and thence through the pipe 07/, T-coupling 30, and pipe 31 into the air-receiver b to equalize the pressure. This particular construction of valve for controlling the admission of air is employed for the reason that it is air-tight. A pipe d leads from the T-coupling 30 to a short vertical pipe (1 which rises to a height just above the carbureter O, and a short horizontal pipe d is connected to the upper end of said vertical pipe (Z and to the opposite end of said short horizontal pipe (1 a vertical pipe (1 is connected, which passes down along the side of the carbureter G to a valve (1 at or near the lower end of said carbureter O, and from said valve (1 a pipe connects with the lower end of the carbureter, and as the air receiver Z1 falls the air contained therein is forced through the pipe 31, T-coupling 30, pipes (Z d d (Z and valve d and thence to the carbureter O to mix with the hydrocarbon liquid which is being supplied.

A valve d" is placed in the pipe (1* or at some other convenient point to permit passage of the air from the falling air-receiver b to the IIO carbureter, but which closes when the pressure is removed-as, for instance, while the air-receiver Z) is being drawn up by the action of the water admitted under pressure, and during which time the air is being drawn into said cylinder through the inlet-valve.

The hydrocarbon liquid to be consumed is contained in a supply-tank P, which may be located at any convenient or suitable place, and said hydrocarbon liquid is delivered in its liquid state to the carbureter O, entering at the top thereof and being converted into gas as it passes downward, and to accomplish this result a delivering, device of novel construction is employed, which is operated by and consequently conjunctively with the airpressure device, so that a proper delivery is insured of both liquid and air in uniform proportions, yet the delivery of the liquid is absolutely dependent upon the operation of the air-pressure device, and this conjunctive action of the delivering device and airpressure device and the dependence of the action of the former on the latter constitutes one of the most important features of this invention. The said delivering device (see Fig. 3) consists of a long tube or cylinderf, which is secured in a vertical position to an upright 12 on the frame If 'and said tube or cylinder contains the hydrocarbon liquid which is to be delivered to the carbureter, and said tubef is closed at both ends, except as hereinafter described, to thereby form a liquid holding receptacle. f represents a short tube or cylinder which loosely fits and is adapted to work up and down within said long tube or cylinder f, it acting by displacement as it falls to cause the hydrocarbon liquidto rise in the cylinder, and to thus expel it, The tube f is attached to and suspended from a vertical rod f which passes up through a hole in the top of the cylinder, and the upper end of said rod f is connected by a rodf to the rod on, so that said rods f 3 and 177, will move in unison, and as said rod on" is attached to the air-receiver b of the air-pressure device and moved by it said rod f and inner tube f, supported by it, will be correspondingly moved up and down with said air-receiver b.

Contained within and located near the bottom of the tube or cylinder f is a valve f shown as a plug, made considerably smaller in diameter than the interior of the tube f and having its lower end formed to seat upon and close the upper end of an inlet-pipe s, which projects up into the lower end of the tube f, passing up through a cap or nut s, which is screwed onto and closes the lower end of said tubef, and said valve f is movable toward and from the valve-formed end of said inlet-pipes to open and close the outlet of said pipe. The pipe 3 serves as an inlet-pipe for the admission of hydrocarbon liquid to the tube or cylinderf, and said inlet-pipe s is connected by a short pipe with a stand-pipe 0 at .9 as hereinafter described and said stand pipe 0 is kept continously filled with the hydrocarbon liquid to a predetermined elevation. The valve f is attached to the lower end of a rod f which projects up into the inner tube or cylinder f, which is contained within the tube or cylinder f, and the upper end of said rod f is bifurcated or 0therwise divided into several fingers which are sprung apart and caused to engage frictionally the interior of said inner tube or cylinder f. By thus frictionally connecting the rod f, to which the valve is attached, with the short tube or cylinderf", said valve will be raised and lowered by said tube or cylinder f A pin 00 is passed through the wall of the cylinder f near its lower end, which projects into the upward path of movement of said valve f and said pin 00 serves as a stop to limit the ascent of said valve f As the tube f is raised the rod f having the bifurcated end in frictional engagement with the interior thereof, will be drawn up with it, and the valvef will ascend until it strikes against the pin at, and then as the tubef continues to rise the valve f will remain in engagement with the said pin a;, the bifurcated end of the rod f at such time sliding along in said tube. As the tubej descends the valvef will descend with it until it strikes and is seated upon the upper end of the inlet-pipe 8, closing said inlet, and then owing to the frictional sliding connection of the rod with said tube f the latter may continue to descend for the purpose of expelling the liquid contained in a cylinder f by displacement. Thus the valve f will be lifted and removed from its seat at the beginning of the ascent of the tubef; but its ascent will be checked by the stop at, and by means of the sliding connection of the rod with said tube f said tube f may continue to ascend, holding the valvef up against said stop, and as the tube'f is connected with the air-receiver b said tube will rise conj unctively therewith, and the result is that the valve remains lifted and open during the time the air-receiver is rising to store up a supply of air, and during the time that the valve 1" is thus elevated the hydrocarbon liquid is free to enter and rise in the cylinderf to a predetermined elevation. Thus a quantity of air and a quantity of hydrocarbon liquid are stored up in their respective receivers to be subsequently delivered, and it will also be seen that the valve f will be caused to descend and to close upon its seat at the beginning of the descent of the tube f to thereby close the inlet, and by means of the aforesaid sliding connection of the rod f with the tube f said tube f will be permitted to continue its descent con j unctively with the gravitating air-receiver and,falling in the liquid contained in the cylinder,will act by displacement to expel the liquid, delivering it to the carbureter conjunctively with the delivery of the air.

Leading from the cylinder f of the delivering device, near its upper end, is a small pipe 7L which extends to the carbureter O, and

the hydrocarbon liquid contained in said cylinder f is expelled and caused to pass through said pipe 7L to the carbureter as the inner tube f descends.

As the tube f is connected with the air-receiver, as before described, it will be seen that it will descend with said air-receiver and will cause the liquid contained in the cylinder f to pass through the pipe If at a certain speed proportional to the descent of the airreceiver, so that the liquid and air will be delivered to the carbureter in uniform proportions and the delivery of the liquid will be absolutely dependent upon the delivery of the air.

It is designed that the hydrocarbon liquid shall rise in the cylinderfto a predetermined height when the inlet-valve is open to thus regulate the quantity to be used proportional to the air which is supplied by the airreceiver, and to accomplish this result we employ a stand-pipe 0 which rises from a supply-tank P to asuitable height and which is kept filled with hydrocarbon liquid to a predetermined height or above a certain level by means to be described, and said stand-pipe 0 is tapped at .9 and the inlet-pipe s is connected to the stand-pipe at such point and enters the lower end of the cylinder f, as before described, and the passage through said pipe .9 is controlled by the valve f moving toward and from its inner end, and when said valve is open the hydrocarbon liquid will rise in the cylinder f to a level with the liquid contained in the stand-pipe 0 The outlet h of the cylinder f is just at or above the normal level of the hydrocarbon liquid contained in the standpipe 0 but the liquid is expelled through said outlet 71 by displacement produced by the falling tube f when the valve f is closed upon the end of the inlet-pipe s and is conducted to the carbureter C.

To maintain the hydrocarbon liquid at a predetermined height in the stand-pipe 0 we provide a tank 0', (see Figs. 1, 3, and 5,) which contains within it a vertical partitionwall 0 dividing it into two compartments 4 and 5, and said partition-wall 0 terminates just above the bottom of said tank to allow free and unobstructed passage beneath it, as at 2. The stand-pipe 0 rising from the supply-tank P, extends a short distance above the tank 0 and has a T-coupling c at a point about on a level with said tank, from which a short bent pipe 0 leads to said tank, opening into the compartment 4 thereof at a point substantially midway the height of the tank. NVater is introduced into the tank 0 in suitable quantities, which upon rising therein high enough will enter said pipe 0 and pass down the stand-pipe 0 into the supply-tank P and upon settling to the bottom of said supply-tank will displace a corresponding quantity of hydrocarbon liquid, which will rise in said stand-pipe and will enter the compartment 4 of the tank and float upon the surface of the water therein. The water is introduced into the tank 0 by a pipe 0, which is connected with the cylinder b containing the piston a, and as said piston (1/ falls the water will be conducted into the compartment 5 of the tank 0' by said pipe 0. It will be seen that the cylinder 1) is not vented, and hence the water will be retained therein and will only pass out gradually as the piston a falls, although it is obvious that the water might be allowed to escape at once and be conducted to the tank 0, and in either case the result will be the same. The water upon entering the compartment 5 of the tank 0' passes beneath the partition-wall c ,"and thence into and down the stand-pipe 0 but to provide against the passage of too much water and consequent trouble which might arise an overflow or waste pipe 6 is provided in the compartment 5 of the tank 0', the upper end of which terminates substantially on a level with the center of the pipe 0 and if more water enters than is required to raise the hydrocarbon liquid to such a predetermined level in the compartment 4 of the tank 0 then it will be carried away. Thus it will be seen that the hydrocarbon liquid and the .Water establish themselves in the tank a in a ratio corresponding to their respective specitic gravities. Referring to Fig. 2, the dotted line indicates the level of the water in the compartment 4, above which is the hydrocarbon liquid, and it will be understood that said hydrocarbon liquid is maintained at such a predetermined height and that the stand-pipe 0 will consequently be filled to such a level, and when a quantity is taken from said stand-pipe to fill the cylinder f of the delivering device the predetermined level in the tank 0 will necessarily fall and the Water will rise in said compartment 4 and soon will reach such a level as to enter the pipe 0 and to flow down the stand-pipe 0 into the supply-tank P and to cause a corresponding quantity of hydrocarbon liquid to rise. Thus it will be observed that the hydrocarbon liquid is automatically maintained at a predermined height in order that the delivering device may be refilled as desired.

The carbureter or converter or mixer 0 consists of a tank which contains within it a coil or worm (P, the upper end of which is connected with the pipe d and the lower end of which is connected with the pipe W, and said reservoir is adapted to be filled with water, which may be warm, if desired, to facilitate the evaporation into gas of the hydrocarbon liquid. The hydrocarbon liquid expelled from the cylinder f at 71 passes along said pipe b and is delivered into the pipe 01 at a point near the connection of said pipe d with the coil or worm d and then passes down through said coil or worm and meets an inflow of air, which enters said coil or worm at the bottom through a pipe 61 and the liquid is converted into gas by being taken up or commiugled with the air before it reaches the bottom of the coil, and as a consequence there is no waste.

Anindicating device is preferably provided to ascertain whether or not the machine is in operation, and, as herein shown, such indicating device consists of two pipes to u, (see Fig. 4,) brought nearly together and inclosed within a case it, having a glass front, so that the dropping of the hydrocarbon liquid can be seen. This indicating device is connected in the pipe 71 which leads from the delivering device to the carbureter.

The gas generated in the carbureter passes through the pipes 01 (Z d (Z and (Z to a receiver 92 which may be the rising-and-falling tank of a gasometer of any usual orsuitable construction. The passage of the gas along said pipes to the carbureter is controlled by a pressure-regulating valve.

The pressure-regulatin g valve herein shown and which is preferably employed consists of a sleeve f, placed within a T- coupling (see Fig. 1,) a plunger 3 which fitstightly into the said sleeve 2 and which is connected to a rod which projects vertically out of the top of the T-coupling, and a lever g pivoted to an upright arm 3 secured to said rod and resting upon the top of said gas-receiver or gasometer The height of the receiving-tank x of the gasometer remains constant while the airpressnre device is descending, and the pressure-regulating valve admits gas to the gasoineter as fast as the gas contained in the gasometer is consumed.

While the cylinder 1) of the air-pressu re device is being lifted the receiver 00 of the gasometer falls to supply the consumption of gas during such interval of time; but as soon as the air-pressure device is refilled and its air-receiver again begins to descend the receiver m of the gasometer rises until an equalization of pressure is again established.

When the supply tank P becomes filled with water, it will be pumped out in any suitable manner before it is refilled with hydrocarbon liquid.
