AGETYLENE GAS GENERATOR.

ATTO R N E ofthe chamber so as to admit sullicient liggjht ttion bolted npon the top 'of said tank, a

to ei'mit.ready'observation of its contents.

Water gage l) is conneeted'ivith the ueneratingv chamber 'so as to afford 'a inca-ns of determining the level of water therein.

For convenience in drawing; oil' the `crater andsediinent from the generatingchamber l lprovide a 'blonofl cock d in the bottoni of this chamber which when open will permit,

the' blowing out-of the tank.

' e i'e nesents the cover for the carbid chamber which is held .in place by the clamp 7' the latter having' a clamp screw q passing' therethrough adapted tobear upon the cover and i5 force it against the packing ring' i, and as the clamp is provided with hookedcnds for engagement with the flange of the casing' it may berreadily removed by simply barking' Off the clamp screw' g and sliding the clamp sidewise after Which the cover may be lifted from its place. Y

In Fig. 2 I have shown a slight modilication of the valve actuating mechanism which consists in pivotiii the lever to the bracket and connecting' said lever with the lever G by therod thus when the rod I is vforced upward the i'od is forced downward and the valve AF is forced upward allowing a further 'flow of carbid and when the floating;

tank O rises the projection P thus releasinii'v the lever .l and permittingr the valve F to be closed by action of the weight R suspended from the lever J the yvalve E in this case acts to spread the carbid aroundin the Water in the generator. v

Among the principal advantages of my improvement is the safety valve .F which absolutely prevents Vthe excessive generation of into the generating chamber.

'gas and consequent damage should the valve mechanism become disairanged or broken, v.for 'inV this case the safety valve i'emains 'j closed and prevents the further 'flow of carbid 4 Another advantage of my ,present improvement is. the spreading' and imitating' eap .L which greatly facilitates'the lregulation of thevfeeding of the carbid. y

Having thus fully described niy invention, What liclairn as nov.' and useful, is-'- 1. An acetylene gas generator consisting,l of a generator tank, a funnel shaped particarbid holder secured to'said tank and Soparated therefrom by the funnel-shaped paw tition, said .partition haring; an. opening' therein, a valve rod extending; through said opening, a regulating valve secured to said rod and adapted to close said opening, a safety valve also secured upon said rod adapted to close, said opening should the valve i'od er .its connections be broken, a spreader cap fitted loosely upon the rod, a .flared stand pipe connected with the generating tank, a gasometer, the floating' tank of which is adapted to operate the valve rod to open the regulating valve, as speciied.v

2. In an apparatus of the character described, a generating tank, a` carbid tank secured thereto, a funnel-shaped partitionseparating the tivo tanks, said partition having ari/opening therethrough, a valve'rod p assing throuoh said opening, tWo valvesl secured upon saiderod, a notched edge spreading cap covering' the upper valve, said rod passing through said cap so as to vibrate the-latter,

a gasonieter, and means dependent upon the movements of the floating tank of said gasoineter to operate the valves, as specified.

3.v In an acetylene gas generator, a generating tank, a funnel shaped'partition secured.

upon the top of said tank, a'carbid holder s ecured upon said partition so-jthat the said partition willserve as a bottom. for said holder, said partition having an .opening in the center thereof, a valve rod extending through said opening, a regulating valve secured t'o said rod below the partition,v a safety valve secured to said rod above the partition, a spreader cap fitted loosely upon said rod, the edges of said capbeingnotched, two transparent sections set 1n the opposite Walls of the carbid holder, a gasoineter, and

4 means dependent upon the movement of the floating' tank of 'saidgasome'ter to operate the valves, as specified.

In testimony whereof, I have hereunto a'HiXed my signature in the pi'esence of two subscribing Witnesses: A

AUGUST J. MARJENHOFE litnesses A. M. ONEILL, A. W. CoNNon.
