Specification of Letters Patent.

Patented Jan. 1%, i911.

To (all whom it may concern:

Be it known that I, HARnrBnoUssnAU, a citizen of the UnitedStates, and a resident of New York, county and State of New York, have invented certain new and use- .ful Improvements in Gas-Generators, of

nnd entirely automatic requiring practically no attention after. beingonce started.

Other objects of the invention are to provide simple means whereby the car-bid may be suspended in the water; and to provide means whereby the water may be prevented I from rising too high in theapparatus.

Another object of the invention is to pro vide simple means whereby water may be forced into the apparatusand by the same means remove the air from within the gen- .erator when the apparatus is started.

A further object of the invention is to provide simple and etlicient means for directing the carbid to the feed, and to provide simple. means whereby he interior of the apparatus is readily accesEihle for cleaning, repairing or for other pu poses.

, Vith these and other ob ccts inview, the invention will be hereinafter mor'eparticnlarly described with reference to the accompanying drawings,.which form a part 'of this specification, and will then be ointed out in the claims at the end of the escription.

In the drawings Figure 1 is a vertical section, partly in elevatlon, of one form of apparatus'embodying my invention. F'g. 2 is a fragmentary sectional plan view 0 the apparatus, partly in elevat on, showingthe feed mechanism. Fig. 3 is-a section, partly in elevation, showing how the pressure of the gas may be made to automatically control the carbid feed mechanism. Fi dis a sectional view of the purifying-andfilteri 2 means for the gas, taken on the line IV-= V of Fig. 1. Fig. 5 is a fragmentary sectional plan, showing one form of means for en mitting the water within the receptacle or apparatus to automatically therefrom in case it rises too high when in operation. Fig. .6 is a fragmentary front elevation of the device shown in Fig. 5; and Fig. '7 is a vertical section, taken on the line VIE-Vii of Fig. 2'.

The receptacle 10 of the apparatus may be of any suitable construction and may comprise an upper section 11 for the carbid, and a lower section for the water or liquid medium. The upper section 11 is provided with a flange 13.nt its lower edge which is clamped by bolts 14, or otherwise, to a. flange 15 on the lower section 1:2, and between the flanges 13 and 15 is held the flanged edge 16 of a hopper 17 in which the carbid is adapted'to be placed. The section 11 has its top 18 provided with an opening 19, and this opening is covered by a cap .or head 2.0. The cap or head 20 has -a plurality of openin s in which are held the covers 21, and sai head 20 is provided with a tubular projecting part 22 which extends outwardly therefrom, and aninwardly pro'ecting tubular part 23 forming substantial y a continuation thereof. A red A extends through the tubular connection 23 and at one end passes through a shitting box 25 and has an operating handle 26 by which the said rod may be rotated. The rod 24. has a threaded portion '27 which engages a nut 28 held in the tubular part 23 so that said red may be raised or lowered, and when raised or lowered will carry a conical which is adapted to artly support and properly direct the carbid as the same passes the hopper 17.

1o properly feed the cal-bid to the water contained in the lower section 12,1 form thp hopper with a tapering bod which terinmates in a cylindrical tubu at part through which the earbid is adapted to pass freel without any obstruction other than the evice 29'. Thelower end of the tubular art 30 is provided with a carbid holder 31, igs. 1, 2 and 7, and this holder may be operated from the'tuhular partBO or formed as a part thereof. As shown, the holder 31 forms a part of the earbid feed and has an inclined side or wall 32 forming an inclined device 29 secured to the lower end thereof 7 base. fo r the tubular part 30, and an outer inclined side or wall 33 arranged angularly with respect to the rear wall 34, Fig. 2, so that the carbid will Jass along the Wall 32 over against the wal 33'wl1ich may extend high enough to prevent the cal-bid frompassing over the same. The space is thus entirely free for the 'carbid to pass to the, holder and to fill'the space between the walls 32 and 33. A star wheel or otheriro- 't'ary or' movable element 35 is held to move ad acent .to the tubular part and has the lower ortion thereof movable in the carbid ho der 31. This wheel is held to rotate with a shaft 36 and has four blades projecting outwardly therefrom, though this number may vary, and these blades are so arranged that they will not offer resistance to the free, feed of the carbid to crowd over a ainst the wall 33, and said blades are simp y-i'ntended 'as a pushing means-for forcing andfeeding a, determined quantity of carbid to;.the water, vIt will be seen that the ca'rbid will fill the spaces between the blades,

and as the element rotates, it will force a determined uantity, according to the spacing of the b ades out through the open-- ing 37 o t the carbid holder, the latter being thereby avoid an explosion, for the Water in the receptacle 48 will fill the pipe 47 in case of back pressure but cannot pass by the check valve 49, the latter, of course, permitting the gas to pass by the same into said tank 48. This tank 48 has a chamber at the upper part thereof connected by a pipe 50 to the lower part of a receptacle or tank 51, and this tank may be filled with mineral Wool and carbid to remove moisture from the gas, and at the lower portion thereof maybe provided with baflled plates 52 and 53 which are angular-1y arranged and are adaptedto assist in collectin the moisture from the gas,.and fitted within the receptacle is a perforated plate 52 and a horizontally-extending plate 54 arranged below the same. to cause the as to take a circuitous route and also to d vide the gas in its passage through the mineral wool and carbid.

Theas passes from the tank or receptacle 51 t rough a pipe 55 which may have branches 56 and 57 controlled by suitable valves 58 and 59, respectively, to be used as desired, a safety valve, as ,59, being provided to prevent the gas from exceeding a. certain pressure within the receptacle 10.

74 opening into the atmosphere connects with the pipe 71 and in this pipe 74 isa valve 75. if the valves 70 and 75-are opened and the pump operated by the handle 72, air may be withdrawn from above the water in the receptacle through the pipe 09 past the check valve 68 and forced into the pipe water near the upper part. thu'cof.

71 out through the pipe 74-, This pumping element may also be'used for pumping water into the receptacle 10 and in this case the pipe 71 is extended to connect with the receptacle 10 and is provided with a valve 76, and the pipe 67 is'extended to connect with a source of water supply and is'controlled by a valve 77. Then it is desired to force water into the receptacle 10, the valves 70 and are closed and the valves 76 and 77 opened so that by operating the pump, water may be forced into the receptacle 10,

and when't-he valves 76 and 77 are closed and the valves 70 and 75 opened, air may be withdrawn from within the receptacle 10 on startin the apparatus as already explained.

As a means for preventing the water from rising too high in the receptacle or casing 10, which might result in the water reaching the carliid in the holder 31. and hopper 17, I provide a float- 78 which is connected '1 a rod 75) to a-valve rod 80. The casing of the receptacle 10 is provided with an opening, and this opening is closed by acap 81 so to permit proper movement of the arm or rod 79 and to form a means to rotatably hold the valve rod 80. as shown in "Fags. 1. 5 and 6.

The rod 80 may operate the plug member 82 of a cock 83, and this cock is connected to the receptacle so that the water may pass th'erethroug'h when the cock is opened by the lifting of the float 78 when the water rises too high witlrin the receptacle 10. i

A safety device is provided in case the water within the receptacle becomes too hot, which permits'the hot water to automatically escape and cold water to How into the As one means I provide a bracltct or arm t t, Fig. 1, which is of more cx'pansible material than the casing of the receptacle l0. and this arm is held in the S5 of less cxpansihle metal or material held to the arm 84, and this arm passes through a stalling box 80 on the' receptacle l0 and connects at its outer end to handles 87 and of the valves 89 and 90 respectively. The valve 89 is arranged in an outlet pipe 91 located near the water line and the valve 90 is arranged in an outlet wipe 92 which may be connected to a suitabie head or supply of water. so that if the water hecomes too heatedpit will cause the arm 84 to -expand and this will operate the arm 85 and through it the valve handles 88 and 87, permitting the water within the receptacle 10 to flow out through the pipe 91 and cold- A rod water topass in through the pipe 92 into the receptacle until the proper temperature of the water is restored. The start Wheel or feed element 85 may be rotated'by any suitable mechanism and this mechanism may be automatically controlled by the pressure of the gas within the receptacle 10 or otherwise' in any suitable manner. As shown, the shaft 36 is held to rotate in a sleeve 93, Figs. 2 and 3, and this sleeve projects through an opening 91 in thecasing and is held in a head or cap-piece 95, which is properly secured to the flange 96 of the receptacle casing. The head or cap-piece provided with a stuffing box 97 for the shaft 36, and this shaft is operated by a train of gears 98. similar to that of the ordinary clock, and this train of gears may be operated by a weight 99 which is held toa rope or other flexible connection- 100 passing around the drum 101 to which one of the gears of the train is held so that by rotating the drum 101, the' mechanism will rotate the shaft 36 and through it the feed wheel or element 35 to feed the carbid to the water. The train of gears 98 operates'a bevel gear 102, and this bevel gear is in mesh with a smaller bevel gear 103. The gear 103 is held to a shaft 104 and'this shaft is held to rotate in a boss or sleeve 105 projecting from a normally fixed governing element or block r 106 located on the gear frame 107. A

bracket 108 extends upwardly from the frame 107 and on the bracket is a normally fixed governing element or block 109. blocks, devices or elements 106 and 109 have one end beveled, as at 110 and movably held between the blocks 100 and 109 is a brake. element 111. This element is provided with a sleeve portion 112 and is slidingly held on the shaft 104, and by means of a feather and spline is adapted to rotate therewith. The brake element 111 has a beveled tapering recess 113 adapted toengage the beveled end of the element 109 and has a tapering or beveled recess 11 1 adapted to engage the beveled end 110 of the element 106 so that when the sleeve portion 112 and brake element 111 is moved upward or downward be yond a normal position sufficiently to engage either of the blocks 100 and 109, it will stop the rotation of the shaft 104.; The shaft-10at at its upper end is provided with pivotally held arms 115 which are normally. forced toward each other by a spring 116, and on the end of the arms 115 are weights 117 which are adapted when rotated beyond a certain speed to engage the inner surface of a ring or device 118 supported on a bracket 10S and thereby regulate the rotary move ment of the shaft 104: if the same exceeds a certain speed. 7

A lever 119 is pivotally held, at 120, to a The supporting bracket 121, and this lever at one or the like; that simple lever 125 will impart a greater movement to its tension varied by means of a wmg or purifying the gas and f r removing the moisture therefrom, and t thesame time means for positively forcing'water mtoltiis having means to enter a groove 123 of the sleeve 112 whereby when the lever 119 is-operated, it will raise or lower the sleeve 112 according to which way it is moved, and at the same time permit rotary movement of said sleeve. The lever 119 is pivotally held, at 124, to the end of a shorter lever 125, and this lever 125 is pivoted at 126 to a bracket 127, forming a; part of the casing of a suit able gas regulator 128. This regulator may be of the usual construction and may have a connection, as 129, to the upper portion of the receptacle 10 in order that-the gas may exert a pressure on the under side of a diaphragm 130. The diaphragm 130 is adapted to move a device or arm 131 connected to the levers 125, so that a slight movement of the the lever 119 and thereby the brake element 111. The lever 119 has a rod 131' connected thereto at one end, and this rod passes through a tubular part 132 of the regulator casing, and said rod is normall forced in one direction by a spring 133 whic may have other nut 134. The action of the ring 133 against the outward movement Z? the diaphragm I30 so that the action of the brake element 111 ma be regulated according to the pressure in the receptacle, 10. The mechanism thus described, serves as a very efieo tive-means for controlling the operating mechanism of the feed.

From the foregoing it will be seen that a ve simple and efiective feed is rovided WhlCh permits" a free flow of the car id, and which will positively 'force and deposit a determined quantity of the carbid at eachmoveinent of the movable feed element; that effective means is provided for regulating the speed of the feed automation ly an through the ressure. of gas-in the apparatus; that e ective means is provid for om aback-flash is provided for cleaning the apparatus that sa d appe ratus is so constructed as to self-contained preventing an explosion and automatic in its action sothat .very little attention is required;-t at simple means is provided for regulating lie-normal water line to prevent the water from reachingthe stored carbid; that simplem'eansis vided for regulating the tem ratureo water so as to automatical ysupplys eold" water to the receptacle injcaee the water therein becomes too hot' and to provide receptacle. or to remove air therefrom 'whenstarting the-apparatus. -T v 7 Having thus described my invention, ;1 claim as new and desire to secure by Letters Patent Y 1.
