To all whom it may concern.'

- Be it known that I, ALGERNON S. PHELPs,

J r., a citizen of the United States, residing in Chicago, in the county of` Cook and State of Illinois, have invented a new and useful Improvement in Acetylene-Gas Generators, of which the following is a speciiication.

My invention relates to improvements in acetylene gas generators.

The obj ect of my invention is to provide an acetylene gas generator, of a-simple, efficient, durable and safe construction, which will regularly and uniformly in measured charges as the gas is consumedyand whereby all danger or liability of delivering an excessive quantity of carbid to the generator and producing an excessive or unsafe pressure of gas My invention consists in the means I have devised and employ to accomplish this object or result, as herein shown and described, and more particularly specified in the claims.

-In the drawing forming a part of this speci fication, Fi ure 1 is a central vertical section of an acety ene gas generator embodying my invention showing some of the parts in elevation. Fig. 2 is a detail elevation of the carbid magazine and feed mechanism. Fig. 3 is an elevation of the same looking from the opposite side. Fig. 4 is a detail vertical section on line 4-4 of Fig. 1. Fig. 5 is a detail horizontal section on the broken line 5 5 of Fig. 2. Fig. 6 is a detail horizontal section on the broken line 6-6 of Fig. 2. Fig. 7 is a horizontal section on line 7 7 of Fig. 1. Fig. 8 is a detail vertical section on line 8-8 of Fig. 7 and Fig. 9 is a detail plan view of a part hereinafter to be described.

In the drawing, A represents the main tank of my acetylene gas generator. The tank A has at its lower portion a generator chamber A1, and an upper chamber A2 for the gasometer, the two compartments or chambers being separated by an annular dome shaped partition a, having a central tubular extension al.

B is the carbid holder or magazine fitting within the central tube a1.

C is a cylindrical hood or seal which fits over the central tube al and the carbid holder within said tube and to which said holder is attached.

D is the bell or gasometer, the same being of annular form, having an outer wall d fitting within and concentric to the cylindrical wall of the tank or casing A, and an inner wall d1 eccentric to the wall d and surrounding the central tube e1 and hood or seal C, the eccentricity of the inner wall d1 serving to give space between said inner wall d1 of the bell or gasometer and the hood or seal C to receive and accommodate the connection rod of the carbid feed mechanism.

E is the filter, the same consisting preferably of a cylindrical closed shell secured to the horizontal annular partition o and containing filtering material E1 of any well known kind.

G is the gas pipe extending through an opening in the annular partition a and secured thereto by lock nuts g g and through which the gas from the generator chamber A1 is conducted into the gasometer. The upper end of this tube projects above the water level in the tank A and is covered by a closed hood G1, the` lower end of which extends below the water level and is provided with ine perforations g1 through which the gas escapes into the water. Over the hood G, there is provided an outer hood G2, the lower end of which extends below the lower end of the inner hood G1, and the upper head g2 of which is provided with perforations g3 through which the gas escapes into the gasometer.

The gasometer D is furnished with a dome D1 which telescopes with the hoods G2 G1.

E2 is a pipe, the upper end of which communicates with the gasometer above the water level, and by which the gas is conducted from the gasometer into'the iilter E.

E3 is the gas conducting pipe leading from the filter to the service pipe E4 on the outside of the machine.

E5 is the drip pipe communicating with the' ipe E2 and service pipe F.4 and having its ower end extending into the b v-pass box F.

F1 is a blow-off pipe communicating at its l ometer is raised by the gas pressure above the height desired. K,...

F3 is a pipe extending through the outer wall of the tank, having a stop cockf 1, and communicating at its outer end with the bypass box F. The inner end of this pipe F3 determines the water level x1 in the lower or generator chamber A1 and also gives vent into the by-pass box F when the stop cock f1 is opened. The handle f 2 of the stop cockf1 is provided with a bent arm f3 having a foot f1 which serves as a lock to the gate or faucet]p5 by which the water is removed from the generator chamber A1 of the tank A to recharge the machine. This prevents opening the gate or faucetf5 before opening the stop cock f1 which gives vent into the by-pass box.

The by-pass box F is furnished with an overflow pipe f6 having an interior nipple f7 extending nearly tothe bottom of the by-pass box F, which regulates the water level x2 in the by-pass box F so that an air space is always maintained at the upper part of the by-pass box as required. y

The carbid holder or magazine B is provided at its lower portion with an incline b, giving the magazine a hopper shape, and terminates at its lower end in a reversely inclined chute B1, the lower inclined wall b1 of which is preferably rounded or curved, and the upper inclined wall b1 of which is preferably provided with an internal ledge or shoulder b3 to give the chute or passage B1 a contracted throat B2. The throat B2 is preferably furnished with a substantially upright wall b1 on the side opposite the incline b1 so as to give the feed passage B1 a downwardly opening mouth B3.

H H1 is the feeder by which the carbid is fed automatically and regularly in measured quantities from the holder or magazine B into the generator chamber A1, the same comprising a rocking shoe H and a tilting dump pan H1 arranged below the shoe, the rocking or swinging shoe moving concentric or parallel to the curvature of the dump pan so as to avoid any wedging, clamping or binding action upon the carbid material between the dump pan and the swinging shoe The shoe H has a crank arm h pivoted to the lug b5 on the chute B1 by suitable pins h1. On the pivot 71,1 of the arm 7L, a lever 77,2 is fulcrumed to the lower end of which is pivoted the hook lever h3 by a pin h1, the hook lever h3 having a downwardly opening curved or wedging slot r" to adapt the hook lever to readily engage the bail or crank M, through which motion is communicated to the rocking shoe H from the gasonieter D. To facilitate the engagement of the hook lever h3 with the bail or crank M when the carbid holder or magazine B is lowered into the central tube a1, the hook leverh3 is furnished with an arm h6 having a notch k7 which engages the lug 126 on the reversely inclined chute B1, thus setting the hook lever in proper` position to engage the bail M. Vhen the engagement takes place between the hook lever h3 and bail M, the further lowering of the magazine causes the bail M to raise the hook lever so as to disengage itself from the lug b and thus leave the hook free to move under action of the gasometcr D. 'lhe rocking or swinging shoe H is provided at its opposite side with an arm LS, carrying at its lower end afriction wheel 7L" which is adapted to engage the curved lower face of the dump pan ll1 and close the same or turn it into a horizontal position beneath the discharge mouth B of the chute as the shoe H begins to swing open and before said shoe moves sul lieientl y in its opening movement to permit the carbid to fall therefrom into the generator chamber A1. rlhe operation of the dump pan is to close or turn into horizontal position before the shoe H in its opening movement begins to discharge the carbid therefrom.

To hold the dump pan ll1 which hinged by a pin 7L to the lugs 1f on the chute B1 in its closed or horizontal position beneath the discharge mouth of the chute while the shoe H is swinging open or out of the. way, the dump pan H1 is provided with a` dog or arm 71/10 which engages a latch or trip device /111 pivoted to the chute B1 or its lugs lf at /1"". The latch or trip device '71,11 automatieally released or tripped by engagement with the arm hs on the rocking shoe H when said rocking shoe H is in its closed or horizontal position beneath the discharge mouth B olv the chute B1 at which time the friction wheel or roller h1 on said arm swings past and clears the dump pan H1, thus permitting the dump pan to swing freely and suddenly open and deliver the charge of carbid therein into the generator chamber. To partially counterbalance the rocking shoe ll', it is provided with a weighted arm t11 and the dump pan H1 is provided with a similarweighted arm h1.

N is an agitator fitting in an opening If in the chute B1 and projecting downwardly into the mouth B3 of the chute for the purpose of preventing danger of clogging. This agitator N has a crank arm n, preferably integral therewith, which fits in an arm 71/11 on the lever h1 fulcrumed on the hinge pin /11 of the rocking or swinging shoe, so that the agitator is automatically operated from and by the shoe H.

Motion is communicated to the bail or crank M which operates the feeder ll [l1 by the up and down movement of the gasometer D by means of a lever P connected to the gasoineter by a pivoted link p and provided with a cam P1 of open slot form which engages the friction roller p1 on the. lever p1 and which is connected by a link p1 with the arm nly ol' the bail or crank M. The lever l.) is fulcrumed at p1 on a bracket p5 on the tank or casing A. The lever p1 is provided with a weight p to turn or hold the crank M in proper position for engagement of its bail arm m1 with the hook lever h3 when the carbid holder or magazine Bis lifted out and returned to position in the central tube a1. By reason of the open slot form of the cam P1 when the gas pressure rises too high, the gasometer operates to entirely disengage the cam P1 from the roller p1 on the lever p2, thus entirely disengaging the feed mechanism from the gasometer. The cam P1 has extended neutral portions p7 p8 above and below the operative portion p, said neutral portions being curved concentrically with the pivot p1 about which the lever P turns, so that the gasometer may have the requisite extent of travel without acting upon the feed mechanism excepting at the operative or inclined portion p1 of the cam.

The generator chamber A1 has an inclined bottom a2, terminating in a drain channel a3 and is provided with a rotary agitator R to stir up the sediment before drawing off the water in the generator-chamber A1 and recharging the same. This agitator R is secured to a shaft r having a crank r1 for operating the same, on the outside of the tank A.

The connecting rod p3 between the crank or bail M and the lever p2 is provided with a link p10 and an adjustable connection therewith preferably consisting of screw threads on the connecting rod p3 and lock nuts p11 p12.
