NARCISSE ALEXANDRE GUILLAUME, OF PARIS, FRANCE.

GAS-GENERATOR.

SPECIFICATION forming part of Letters Patent No. 647,826, dated April 17, 1900.

v Application filed December 27, 1899. Serial No. 741,750. (No model.)

T0 all whom t may concern.:

Be it known that I, NARCISSE ALEXANDRE GUILLAUME, a citizen of France, residing at' 15 Rue du Louvre, Paris, France, have -invented certain new and usefullmprovements in Gas-Generators, of which the following is a specification.

This invention relates to that class of gasgenerators which Work by suction-that is to say, that class of gas-generators in which a mixture of steam and air drawn in either 'by a pump or directly by a motor is caused to traverse an appropriate fireplace or furnace.

My present invention consists in certain novel fuel-charging devices for such gas-generators, one object of which is to avoid the undesirable admission of air to the generator, which generator does not require a grate for the fuel, but which is provided with a sloping fireplace, in front of which is introduced the air and vapor mixture.

In order that my invention may be thoroughly understood, I will describe the same with reference to the accompanying drawings, in Which- Figure l is a transverse section through a I gas-generator to which my improvements are applied. Fig. 2 is a vertical section at right angles to Fig. l. Figs. 3 and i represent a modification in the form ofthe furnace. Figs. 5 and 6 show in section and plan the closed position of the slide.

A feed-hopper a. for the fuel is provided, having a wide mouth or opening t, which is normally closed by a cover c, pivoted at d and provided with a connterweight or counterweights e for the purpose of facilitating the opening and closing of the said cover. 'The lower end of this hopper is provided with a closing-plate t', Which can be slid horizontally to open and close the bottom of the hopper. The pivoted cover c is secured in its closed position by screw-boltsf, carried on a spindle g, pivoted to the body of the hopper, the said bolts being capable of being turned into po sition between ears on the cover c, thumbnuts h being screwed onto thebolts firmly against these ears, so as to tightly secure the cover in its closed position. The pivoted screw-bolts f are connected by arms p and links q, as at r, to levers s on a spindle t, mounted in bearings on the hopper a, the said spindle t having other arms `Lt connected to a bolt w for locking the sliding door t at the lower end of the hopper in its closed position, so that the said sliding door cannotbe moved to open the bottom of the hopper unless the screw-bolts are raised into position between the ears on the cover of the hopper. When the cover is closed and secured by the screw'- bolts f, the sliding door can be opened by means of a hand-wheelj on a spindleLcar'ry'- ing pinion 7c in gear with racks m on the slid'- ing door t'. The sliding door can by this means be opened, so as to completely uncover the bottom of the hopper a, and thus allow any fuel that had been placed in the hopper to drop into a tube n and thence into the gasgenerator proper, o.' The movement of the sliding door 1l to open the bottom of the hopper is not possible so long as the screw-bolts are not in the position to secure the cover of the hopper in its closed position, so that the direct communication-between the interior of the generator and the external atmosphere is prevented. Y Springs x are provided, having the tendency to force the slide plate or doorz' upward. The said door slides between two grooves in the table under which it slides,` and when in its closed position it remains motionless in spite of the draft caused by the suction. In order to insure this immobility and rigidity of the plate z'- and to avoid the springs becoming bent by the effect of the suction and under the weight of the fuel placed upon the said slide plate or door fi, and thus cause undesirable admission of air, I provide above the steam-chamber 14 a number of fixed wedges 22 and a corresponding number of similar Wedges 23, fixed to the lower face of the sliding door t', so-that when the door is moved into its closing position the wedges 23 on the door become wedged up against the fixedwedges and the door will be forced against the base of the feed-hopper a. As the springs a; only work in a very slight measure, they do not become bent, and any return of air will be thus prevented. The fuel passed from time to time into the gasgenerator drops gradually in a sloping direction, as show at y, Fig. 1, in front of the furnace-door z.

The mixture of air and vapor is supplied to the furnace under the action of the draft,

y the'suction taking place through the conduit 1 at the upper endof the generator. The air and the vapor are mixed by regulation-cocks in al 4proportion suitable to insure the proper function of the gas-generator and pass through' a tubular nozzle 2 into a cast-metal box or chest 3, which extends around one-half ofthe circumference of the generator.

' part 4 ofthis curved conduit forms la gutter 5, the objeetof which is topermit'of there-l ception of a thin sheet of water, by the aid of which it would be possible to immediately V discover any return of air in vcaseofany defeet inthe jointibetween the gas-generatorr proper and the apparatus placed at its upper` part. The mixture of air andvapor drawn in by suction at 1 into the curved box or chest -3 descends atboth sides along the gas-generator by thefconduits 6, Fig. 2, which-discharge the gaseous mixture ihrough'suitableorifices 7 atl both sides of the furnace.- Under Y the eifect ofthe suction through the conduit 1 vthe gases are transformed as they pass through the column of fuel'y io, and they spread-out in a chamber 8 above the fueljwhich surrounds the -tube n in communication with the hopp` perthrough which the fuel enters the genera- "tor,` The suction producedin the conduit 1 by thepump extracts the gas from the generator by the intermediary of a bell-shaped or arched vpassage 9, separated .from the main gas-chamber S by means of an annular plate 10, provided with orifices of variable diameters, in such a manner that the resistance opposed to the traversing of the annular or bellshaped passage and irregularly-perforated' plate 10 will be nearly the same throughout the circumference. 'The effect of this arrangement is to produce an absolutely-regular draft across the whole mass or bulk of the contents of the generator, and consequently to pre vent'the drawn-up gases from traversing the column of fuel by following all the same course-nam ely, that offering the least resistance-whereby gases unsuitable for efficient use would be obtained.

When it becomes necessary to stoke the fire andto remove cnde'rs and residues from the v furnace, the furnace-door z is opened, which door is providedV with a counterweight,the pivot 11vof which is connected in a suitable manner to the seat of a cock 12, placed on a secondary steam-cond uit 13, forming a branch Y of the main conduit. By opening the furnacea modification in the arrangement of the gas- The upperA generator, according to which the 'entrance to the furnace presents the shape of a vault and the capacityof the gas-generator is increased by dispensing' with the conical reduced portion at thevlower part. Above the steam-chamber 14 a pressure-regulatin g valve 15 is provided, which valve comprises two differen tial pistons 16 17 one of which, 16, covers p the entrance of the exhaust-pipe 18, while the other, 17, allows steam to enter the chamber 20, placed at the upper part of the valve and provided with a series of small orifices 19.

When the pressure in the steam-chamber 14 and17, will lift them until the piston 16 covers the entrance of the exhaust-port 18.. When the `decrease in the pressure resulting from the loss of vapor is sufficient, the pistons will descend. In the opposite case the vapor, actving upon the other piston 17, will continue to lift the latter until it touches the cover of the chamber 20. At this moment the vapor'will be enabled to freely pass under this piston in the said' chamber` and thence into kthe atmosphere through lthe orifices 19.

. Having now particularly described and ascertained the nature of the said inventionand in what manner the same is to be performed,A

for securing the said plate in its closed position and meansA whereby the top of the hopper is prevented from being opened beforethe lower end of the said hopper is closed by the sliding plate substantially as hereinbefore de= scribed. Y v

2. In ay gas-generator operating by suction a fuel-charging device comprising a hopper closed at itsupper end by a hinged lid or cover secured in its closed position by hinged bolts and nuts, a sliding plate for closingthe bottom of the hopper and a bolt a retaining device for securing the said plate in its, closed position, a system of levers connecting the securingbolts for the top cover tov the boltretaining device for the sliding plate or bottom cover so thatboth covers cannot be open at the same time and springs arranged. beneath the sliding plate to press it against the bottom of the hopper to prevent vibrations of the plate by the action of the suction pump or motorsubstantiallyas hereinbeforedescribed.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
