- Application filed January 22, 1906. Serial No= 297.3750.

To 1r/Z whom it may concern:

Be it knownthat I, FREDERICK F. CAVE, a citizen of the yUnited States, residing at Los Angeles, in the county of Los Angeles and useful Improvements in Acetylene-.Gas Maclnnes, of which the following is a specification. y

v My invention relates to that class of acetylene-gas machines in which the vcalcium carbldls'dropped into the water; and the object of my invention is to produce asimple, compact, and c flicient machine in which the supply of carbld will be fed into the water as fast as the gas isneeded for use. I accomplish and `illustrated in the accompanying drawings,I in which* e o Figure lis a'central vertical section of my machine. Fig. 2 is a section on line 2 1. Fig. 3 is a detail'` of the feed-valve.

In the drawings, 4 is the usual water-tank,`

which in my machine Iv utilize as a generatorchamber. Vertically movable in the watertank is the gas-bell 5, which is provided with guide-pulleys 6, which engage guide-bars 7,

' secured to the tank, thereby guiding the bell.

The carbid-chamber 8 has a downwardl -projecting delivery spout or tube 9, whic jects throughthe centerof the top of the gas-bell and is secured to said bell. This spout forms the outer casing of the feeding mechanism. Within the lower endv of this spout and vertically movable therein is the feed-valve 10, which consists of a hollow tube open at the upper end andclosed at the lower f end and having elliptical openin 1 1 in one side thereof. .To the lower end of t e tube is secured a stem 12, and to the lower end thereof is secured a weight 13 by means of chain 14, or the weight' could be directly attached thereto. Secured to the/top of the gas-bell and projecting downwardly therefrom 'are yokes v 15 and 16.. In these yokes are pivotally mounted the valve- operating levers 17 and 18, which have longitudinal slots 19 and 20\ in theirllower ends. One of these levers is on one side of the valve-stem and theother lever is on the other side of the valve-stem, and pins 21 pass through the slots inlthese levers and through the valve-stern.- To the outer ends of these levers are secured chains 22 and 23, upon the lower ends of which are carried weights 24 and 25, which weights rest upon supports 2'6 and 27 when the valve is lly opened, as shown in the drawings. A

invented new and 1 2 of Fig.

pro-

guide and sealing tube 28 is secured to the top of the gas-bell.l A U-shaped valve-closin rod 2 9 is secured to the lower end of the'v Yva ve-stem at one end and passes upwardly in guide-tube 28 and tothe upper end thereof handheld 30 when reiilling the machine.

I first close the valve by pulling on rod 29.

I then take cap 33 ofi' the carbid-chamber and fill the same with carbid. I then replace cap 33 and then gradually open the valve by led by pipe 34 out of the bell, passing downwardly and out near the bottom of the tank, where it is connected with a service-pipe 35, which leads the gasto its place of use. On vthe lower end. of this service-pipe is a cock 36, through which any moisture may be drawn from. the pipe. A cock 37 on the servicepipe is closed whenever it is desired to cut ofl" the gasfrom the place of use. To clean out the ash,`I have provided a pipe 38, which is provided with gate 39, and water may be supplied to the water-.tank through the pipe 40.` A stirrer-blade 41 has an operating-handle 42, which projects upwardly through a seal-- .be observed that as soon as weights 24 and 25 arel supported the further movement of the gas-bell downwardly will enable weight 13 to open the valve to permit the carbid to flow into the water.

Cross-bars 44 and 45 connect the lower end of the supporting-yokes together and form a y guidefor the lower end of the stem which "passes through them vand at the same time forms a stop to prevent the inner ends of the levers from .movingl downwardly after the valve-tube opening as passed below the de liveryspout, as shown in Figs. 1 and 3.

As the opening in the valve-tube is prefer- Ioo ablyzelliptic'al, it will be seen that. a very small quantity of carbid will first escape and that as the valve is opened wider a .greater quantity will be permitted to iiow into the- IIO Zwater. This is particularly important, as if a single light is being used the valve will only open suiiiciently to permit enough carbid to fall into the Water to generate suiiicient for this single light; and if more lights are used more carbid drops into the water, and at all times no more carbid is generated into gas than is required for use at that particular time. I have provided, however, a surplus of gasspace in the bell, so that it will furnish gas for the lights for some little time after a supply of carbid is exhausted It will be observed that byfeeding into the Water only the amount of carbid necessaryT to produce the gas required for use at that particular time the pressure on the gas is kept even and the lights do not flicker. It will also be observed that I have provided amachine of very compact form and simple construction.

Having described my invention, what I claim isl. In an acetylene-gas machine, a Watertank; a gas-bell vertically movable therein; guides for said gas-bell a carbid-hopper upon the top of the bell and having a deliverytube projecting into the bell; a tubular valve having an open top, a port in the side thereof and a closed bottom vertically movable within said delivery-tube; a weight connected to the bottom of said valve; levers carried by the bell and operatively connected to said valve; and Weights operatively connected to the outer ends of said levers.

2. In an acetylene-gas machine, a watertank; a gas-bell vertically movable therein; guides for said gas-bell; a carbid-hopper upon the top of the bell and having a deliverytube projecting into the bell; a valve on said delivery-tube comprising a tube open at the upper end and vertically movable in said d elivery-spout, said tubeb eng closed at its lower end and having an opening m one side thereof a stem secured to the lower end of said tube; supports secured to the top of the gas-bell and projecting downwardly therefrom one on each side of said delivery-spout; levers having slots in the ends thereof pivotally secured to said supports; a pin passing through said slots and through the stem secured to said valve; weights secured to the outer end of said levers; a weight secured to said valvestem; and a stop to hold the inner ends of said levers against too great downward movement.

In witness that I claim the foregoing I have hereunto subscribedl my name this 13th day of January, 1906.

FREDERICK I). CAVE.
