ACETYLENE-GAS APPARATUS.

SEIECIFIGATION forming part of Letters Patent N 0. 712,1 16, dated October 28, 1902.

Application filed April 4, 1900.

To all "whom, it Wtcty concern:

Be itknown that LEUGENE BOURNONVILLE, a citizen of the United States, and a resident of Jersey City, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Acetylene- Gas Apparatus, of which the following is a specification.

My invention relates to improvements in apparatus for producing acetylene gas; and it consists in the novel features and combinations hereinafter described, and particularly pointed out in the claims.

My invention is presented in this application in an apparatus comprising ageneratortank containing water, a gasometer receiving the gas f om said tank, means operable from the gasometer for feeding charges of the carbid to the said tank, and an outlet-pipe for gas from the gasometer, and the purpose of my invention is to improve such apparatus as a whole and also in its details.

My invention pertains more particularly to novel automatic means for feeding the charges of carbid to the generator-tank, to means intermediate the gasometer and the feed-wheel whereby the latter at the proper time and to the proper extent is actuated by the movement of the gasometer, to novel features hereinafter described pertaining to the generator-tank, and means for controlling and delivering the gas from the generatortank to the gasometer, and to novel features whereby the attendant may withdraw the water and deposits from the generator tank without interfering with the continued use of the apparatus.

The invention willbe fullyunderstood from the detailed description hereinafter presented, reference being had to the accompanying drawings, in which Figure 1 is a side elevation of an apparatus constructed in accordance with and embodying the invention, parts being shown in section. Fig. l isasectional View of the trapped funnel. Figs. 2 and 2 are views of the sealtrap. Fig. 3 is a vertical section of my generator. Fig. 4 is a plan view thereof. Fig. 5 is a plan view of the trap. Fig. 5 is a cross- Fig. 6 is a detached view 'within the auxiliary tank 1.

Serial N5. 11,451.- oa model.)

of the feed-wheel. Fig. 7 is a view of amodifled form thereof.

The casing A constitutes a generator-tank, into which the water is poured through the trapped funnel E. This casing A is divided into substantially'two sections, (lettered B and O.) A portion of said tank is partitioned ed by the plates G and H to form an auxiliary tank Ito receive the gasometer J and the water, (lettered K,) which is entirely separated from the water in the main tank and is employed as a seal for the gasometer The gasometer J is of customary form, construction, and operation and is adapted to have a vertical reciprocating movement The water K, employed for sealing the gasometer J, is never in communication with the water in the main tank A and is supplied to the tank I by being poured into the upper end thereof.

The bottom of the generator-is substantially fiat and one side is in the form of an inverted cone and the outlet therefrom is controlled by a valve L, which when opened will permit of the escape of the water from the tank A and all sediment and waste products which may have accumulated within the said tank A. Upon the flat part of the bottom of the generator is provided the scraper-blade M, to which is connected an operating device N, and which by means of the said operating device N may by given a revoluble movement over the said bottom for the purpose of loosening the waste products therefrom and causing them to pass into the cone-shaped outlet portion of the section B.

Within the auxiliary tank I is provided the vertical cylinder P, which extends upward from the partition H to within a short distance from the top of the casing of the generator and is provided upon its upper end with a layer of filtering media Q, confined between perforated or porous plates, cloths, or housings R R. The cylinder P is less in diameter than the diameter of the gasometer J, and said gasometer passes downward over said cylinder, as illustrated in Fig. 3. p The upper end of the cylinder P will always be above the water-level in the auxiliary tank I. The partition H below the cylinder P is open,

as at s, and through this opening, in the manner hereinafter described, the generated gas passes upward to within the cylinder P and thence passes through the filtering media Q 5 and into the gasometer J.

The calcium carbid is fed to the generating-chamber of the casing A through the chute T, which is located adjacent to the upper portion of said section B and has its delivery end considerably below the water-level in said casing A. The chute T communicates with the interior of the section B, and hence becomes substantially filled with the water, and said chute at its lower end, which projects into the section 13, comprises the opposite sides VV and downwardly and inwardly inclined bottom V, upon which the calcium carbid will fall and which will direct said carbid inward to a proper extent within the section B. The sides W of the lower end of the chute T are led high enough to prevent the passage of any gas into the chute T and are not connected within the section 13 except by the aforesaid inclined bottom V and by an :5 outwardly and downwardly inclined plate X,

whose purpose is to deflect inward any ascending gas which in the absence of said plate might be inclined to pass out through the chute. Such portion of gas as may pass into the lower end of the chute T below and outward beyond the lower edge of the plate W will pass upward through the open space left between the outer vertical wall of the section B and the upper edge of the plate W.

.5 The upper part of the generator is provided with the air-vent valvefin order that the tank may be properly filled and emptied, and this air-vent valve also performs the function of showing when the water is at a sufficient height in the generator-tank.

In some cases it may be desirable to use a trap at the upper end of the generatingchamber to prevent backflow of gas when cleaning. This construction is shown in Figs.

5 2 and 2.

5 in Fig. 2, whereby the water seal 6 is formed,

through which the generated gas must pass on its way to the upper end of the section B. In addition to the formation of the water seal 6 by the deflecting-plates c d the plate (1, in

connection with the adjacent side wall of the section B, forms a receptacle which will hold water sufficient to at all times maintain the water seal, and particularly during such periods as the water may be withdrawn from the casing A. The generated gas passes to the upper side of the horizontal partition I), and hence when the water for any reason is 7 withdrawn from the casing A the quantity of l water held by the deflecting-plate (1 will be sufficient to prevent the downward passage of the gas from the upper to the lower side of the partition I), and thus the water may be withdrawn from the casing A and the latter cleansed without danger of the escape of the gas with the water and without interfering with the continued use of the gas within the gasometer J. The lower edges of the deflecting-plate c are preferably serrated to the more thoroughly diffuse the gas passing through the water seal 6 on its way to the upper end of the section B, and thereby prevent flickering at the burners. The horizontal partition Bis wrapped close around and above the inner protruding end of the valve f, which is on the line of the water-level within the section B and which when opened during the filling of the generator-tank with water will permit the escape of all of the air from below the partition I), and thus the formation of an air-cushion below said partition is prevented. The horizontal partition I) is provided with the downwardly-extending pipe g, whose lower end is curved upward, and the purpose of this pipe is to permit a circulation of the water from the upper to the lower side of the horizontal partition I) when, due to excess of pressure or other cause, such circulation is desired. The upwardly-turned lower end of the pipe 9 forms a water seal and will hold sufficient water to prevent under usual conditions the downward escape of gas through said pipe g when the main body of water is being withdrawn from the casing A during the cleansing of the latter.

Upon the section B of the main casing A is secured the dome h, within which the generated gas passes and from which said gas finds its outlet through the pipe 2', which extends downward from within the dome h to the trap j, Which is secured to the lower side of the partition H and at its upper end is entirely open and in line with the opening .5 at the base of the cylinder 1. The construction of the trap j is more clearly illustrated in Figs. 3, 5, 5 in which it will be seen that said trap is in the general form of an oblong receptacle containing a definite supply of water and having secured therein the elongated frame 7.5, which forms a gas-chamber into which the pipe 0} directly leads and which chamber is sealed around its lower edges with the water within said trap j, as shown in Fig. 3. The frame is of metal and secured to the trap j, and the sides of this frame 70 are serrated, as shown in Fig. 3, in order that the gas which passes into the chamber formed by the frame it may when escaping around the lower edges of the said frame be diffused by its contact with the serrations at the lower edges of the said sides. The gas which passes from the pipe '6 into the chamber formed by the frame 70 will pass below the serrated edges of the sides of said frame 70 and then ascend through the water held by the trap j and thence pass upward through the opening S into the cylinder P, whence it will pass through the filtering media Q and into the gasorneter J. Connected with the trap jis a pipe m, having on the outer leg the funnel u, said pipe being provided. with the plug 0. It will be seen that by filling this pipe with water the seal in the trap j will be maintained against the pressure of the gas. The plug 0 allowsthe water in the trap and pipe to be drawn off. The gas passes from the gasometer J through the pipe q, as shown in Fig. 3, to the nozzle 4", (shown in Fig. 1,) to which nozzle the customary pipe or tube leading to'the burners may be applied in a well-known manner. The pipe g at a point exterior to the casing A is connected with the safety-seal valve-box or governor F, as shown in Fig. 1.

The calcium carbid maybe fed to the chute T in any suitable manner; but a part of the present invention pertains to the means illustrated in the drawings for effecting an automatic feeding of the carbid to the chute T in proper regulated quantities and through the instru mentality of mechanism connected with and influenced by the movement of the gasometer J. In accordance with this portion of my invention an inclosing casing Sis applied to the upper end of the chute T, and within this casing is mounted upon the horizontal shaft tthe feed-wheel to, which is directly below the downwardly and outwardly inclined wall a: of the hopper A, into which the calcium carbid in bulk will be placed. Attached to this casing Sis a plate S ,wh ich is made to conform to the contour of the feed-wheel and comes close to it to insure the carbid passing forward of the wheel. This plate is placed in the position shown in Figs. 1, 3. It will be obvious that the casing S might be so shaped as to take the place of the separate plate. The casing S extends above the wheel to, and its upper end 0 connects with the outer vertical side of the hopper A at a point directly above the wheel to, whereby there is formed an opening from the hopper A to the wheel 20 which is substantially vertical and tends to direct the calcium carbid on a line toward the outer side of the wheel to. The throat or opening from the hopper A into the chamber formed by the casing S is controlled by the weighted hinged gate D, which has a normal tendency to close said throat or opening and is only opened by the action against said carbid of the wheel w during the rotation of the latter. The action of the Weighted gate D is to prevent any surplus quantity of calcium carbid from being fed to the chuteT and to restrain the carbid upon the wheel to and permit the same to be fed to the machine by said wheel only in the limited quantities desired for the generation of the requisite amount of gas. The upper end of the hopper A is in the form of a hinged door, and thence said hopper may he opened to receive the calcium carbid in bulk and then closed. The upper end O of the casing S is plate S likewise in the form of a hinged door, which may be opened and closed at will, and hence the action of the feed-wheel w and gate D may be inspected at will. Upon the outer side of the casing S is also provided for convenience of inspection and of removal of the feed-wheel a hinged door E'.

Upon the outer side of the section B of the casing A and adjacent to the lower portions of the feed-chute T is provided the verticallyelongated glass panel G, through which the contents of the generator-tank may be inspected and through which also the ebullition created by the conversion of the calcium carbid into the gas may be observed. The glass panel G enables the attendant to observe the condition and action of the water within the main casing A, and thus serves as an accurate means for indicating whether the generator-tank is in proper operative condition and when it is necessary or desirable to with: draw the sediment and water from said tank and clean the latter.

The wheel to is formed as shown in Figs. 6,

"7, the only difl'erence between the two constructions being in one case the flange is straight and in the other it is flaring, the flaring form of flange being adopted to insure the throwing of the carbid in toward the projections on the wheel. These projections are in the shape of ratchet-teeth, as clearly shown in the drawings. By this form of wheel operated by the intermittent mechanism hereinafter described small quantities of carbid are fed intermittently as the volume of gas in the gas-holder diminishes, thus insuring thesuccessive generation of small quantities of gas in such a manner that the pressure of gas in the gas-holder has but a small limit of variation, or, in other Words, that only the exact quantity of carbid necessary to generate gas suflicient to replace that consumed will be dropped on the hopper. I also provide means for preventing any particles of calcium carbid from passing over the flanges of the ends of the feed-wheel and down between said ends and the sides of the inclosing casing S. These means are illustrated in Fig. 3 and consist in cheek-pieces S, Fig. 3, Which project downward from the inner walls of the upper contracted end of the casing S and have extensions w, with curved edges, which are in close proximity to the flanges w. of the wheel. These cheek-pieces extend backward to the It will be seen, therefore, that carbid can only be'fed into the chute by passing forward over the wheel.

A further portion of the invention relates to the means'i'ntermediate the feed-wheel w and the gasometer J, whereby the latter may be relied upon to actuate at the proper time and to the proper extent the wheel to to feed the calcium carbid to the generator-tank, and this portion of the'invention is not limited to the special feed-wheel to, but comprises any feed-wheel adapted to be operated by the means constituting this portion of the invention and located intermediate the feed-wheel and the gasometer. The mechanism constituting this portion of the invention is illustrated in Figs. 1, 3, and 4, and comprises a chain or flexible connection J, positively secured atone end to the gasometer J,and thence extending upward over the pulleys K L, and thence downward to the outer end of the lever M, which is swiveled upon the end of the shaft 25, carrying the feed-wheel w. The lever M is provided with the spring-pawl N, which is in engagement with the ratchet-wheel O, secured upon the shaft t. The lever B is heavier at its outer end, to which the chain J is secured, and hence will descend at that end of its own weight until arrested by the rigid stop P, which defines the limit of the downward movement the end of the lever M shall have. When the end of the lever M is descending of its own weight to the stop P, the pawl N will simply slide over the teeth of the ratchet-Wheel 0 without rotating the latter, and consequently without rotating the shaft t and feed-wheel 20. When, however, the outer end of the lever M is elevated under the action of the chain J, the pawl N will engage the teeth of the ratchet-wheel O and cause the latter to have a definite revolving motion in one direction, and at such time this revolving motion of the ratchet-wheel 0 will be communicated, through the shaft t, to the feed-wheel w, and thus the feed-wheel to will be caused at such period to feed alimited quantity of the calcium carbid to the feed-chute T. The chain J has a fixed connection at one end to the gasometer J and at the other end with the outer portion of the lever M, and that portion of the chain J intermediate the pulley-wheel L and the lever M is preferably provided with the weight Q, which will preserve the chain in a taut condition over the pulleys K L. It is to be observed, however, that the chain J is of such length that it is not taut throughout its entire length except at the definite period when the gasometer J is reaching and leaving its lower position and it becomes necessary to elevate the outer end of the lever M for the purpose of causing the pawl N to rotate the ratchet-wheel O and feed-wheel w. In the condition of the apparatus illustrated in Figs. 1 and 3 it may be assumed that the gasometer J is either ascending or descending. If it is assumed that the gasometer J (shown in Figs. 1 and is ascending, it will be observed that in the natural operation of the weight Q the chain J will be by said weight drawn over the pulley-wheels K and L and will hang downward in a slackened condition adjacent to the outer end of the lever M. On the other hand, if it be assumed that the gasometer J, due to the consumption of the gas, is descending it will be apparent that the weight of the gasometer J will draw on the chain J, and finally when nearly to its lowest position will, by moving all of the slack from said chain, draw the latter to a taut condition from the gasometer to the lever M, and thereupon during the final descending movement of the gasometer J the motion of the latter by continuing to pull on the chain J will effect a limited upward movement of the outer end of the lever M for the purpose thereby of effecting a limited revoluble motion of the ratchet-wheel O and the feedwheel to, the latter being thus caused to feed a proper quantity of the calcium carbid to the chute T. Thus it will be understood that the chain J is never taut except during the final portion of the descending motion of the gasometer J and possibly during the first upward portion of the motion of the gasometer J, the chain being then held taut by the weight of the lever M until the latter has descended to and become arrested by the stop P. It is one of the purposes of this portion of the invention to prevent the gasometer, through the chain J, from acting on the feed-wheel to at any time other than during the final portion of the downward motion of the gasometer J and to provide such actuating means intermediate the gasometer J and the feed-wheel to that the latter may remain entirely idle, except during the latter portion of the de scending motion of the gasometer, and then be actuated by a reasonably-quick motion and only during a limited portion of the movement of the gasometer. The dropping of the carbid into the water sometimes causes water to be splashed up on the wheel, wetting the surface, so as to cause generation of small amounts of gas, which can escape through the top of the hopper. To prevent this, I provide a splash-plate T, which is fixed to the casing below the feed-wheel and extends outward to the feedwheel in the position clearly shown in Fig. 3.

The operation of the apparatus hereinbefore described has been substantially pointed out in connection with the description of the construction of the apparatus. The calcium carbid in bulk will be placed within the hopper A, and the water will be supplied to the generator-tank, the trap j, the blow-off valve or governor F, and the auxiliary tank I. The water supplied to the auxiliarytank Iis simply for the purpose of sealing the gasometer J, and the water supplied to the main casing exterior to the tank I is for the purpose of converting the calcium carbid into the gas, and this water, as hereinbefore described, will fill the generator-tank up to the level of the horizontal partition Z). In first starting the apparatus into actual operation a portion of the carbid will be manually fed to the chute T; but thereafterthe feeding of the carbid to the chute T will be accomplished automatically by the movement of the gasometer J. The gas generated within the tank formed by the casing A will ascend to the chamber above the horizontal partition I) and enter the dome h, whence it will descend through the pipe 2' into the chamber formed by the frame 70, and thence descend around the lower edges of the sides of said frame and after passing through the Water contained in the trap j will pass upward through the opening S and into the vertical cylinder P, from which the gas will pass directly through the filtering media Q and into the gasometer J, whence it will be fed to the burners by means of the pipe q. The automatic feeding of the carbid to the feedchute T is accomplished from the gasometer J by means of the chain J, lever M, pawl N, ratchet-wheel O, shaft t, and feed-wheel w, and, as above described, in the operation of this part of the apparatus the feed-wheel w is maintained entirely idle, except during the latter portion of the downward motion of the gasometer, at which time the gasometer having then drawn the chain J taut will on its final movement downward elevate the weighted end of the lever M, and through the intermediate mechanism above described effect a limited motion of the wheel w, and thereby cause said wheel to carry a limited quantity of the calcium carbid to a position in which it will be left unsupported and be allowed to fall directly into the chute T and be by said chute directed into the water contained within the generator tanln The carbid is directed to the wheel to through the substantially vertical throat and from a hopper having an inclined base, and thereby the bulk of the carbid is largely supported within the hopper and is prevented from having a tenden'cy to leave the hopper with undue speed. That portion of the body of the carbid which is allowed to pass through the throat leading from the hopper A is supported upon the wheel 20 and is retarded in its outward movement by the weighted gate D in its operation and simply presses against and upon the carbid leaving the hopper A by gravity and prevents the carbid from moving with undue freedom over the wheel w. I

The scraper-blade M, having the operating device N, is for the purpose of removing the lime or other deposits from the bottom of that part of the tank A within the influence of the scraper. The withdrawal of the lime and other products, as well as the water, from the generator-tank will be readily accomplished by opening the valve L and permitting the entire contents of the generator-tank to escape.

The employment of the trapj is of advantage in that thereby the gas passing into the cylinder p becomes more thoroughly diffused and said trapprevents the return of the gas from the gasometer J and cylinder P into the generator-tank under any conditions in which it might be desired to open the valve L and cleanse the generator-tank.

The general form and construction of the exterior casing, subdivided by the partitions G H into the generator-tank and auxiliary tank, the latter to receive the gasometer, are of advantage, since thereby a very compact structure having the maximum capacity for the generation of gas is produced.
