i-PECIFICATION formingpart of Letters Patent No. 745,037, dated November 24, 1903. Application filed June 23,1903; Serial No. 162,754. (No model.)

To (2% whom it may concern.-

Be it known that I, CHARLES AUGUSTUS BUTLER, a citizen of the United States, and a resident of Port Townsend, in the county of Jefferson and State of Washington, have in-. vented a new and Improved Gas-Machine, of, which the following is a full, clear, and exact I will describe a gas-machine'embodying my invention and then point out the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a sectional elevation of a gasmachine embodying my invention. Fig. 2 is a plan view of the discharging or feeding mechanism. Fig. 3 is a sectional elevation thereof on theline 3 3 of Fig. 2. Fig. eshows a resetting-bar employed, and Fig. 5 is a sectional detail showing the pawl-and-ratchet mechanism employed.

The generator of the machine comprises a fixed tank 5, in which the bell 6 operates. Arranged in the upper portion of the bell is a funnel-shaped hopper 7, in which the carbid is placed, the same being passed through an opening normally closed by a screwpressed cover 8. Arranged below the hopper is a rotary frame comprising uprights 9,With which the segmental discharging-plates 10 have swinging connection. These plates, as clearly shown in Fig. 2, are pivoted to rods 11, which have bearings in said upright portions 9. These several plates (here shown as four in number) meet at adjacent edges and at the center, the inner ends or apexes, however, being slightly cut away to permit the passage of a turning-rod 12, which is connected to the cross-bars of the frame. This rod 12 passes upward through a tube 13, the said tube being extended through the hopper and into a bell 14, arranged to rotate with 'the rod 12 in a water-cup 15.

The Water in the bell and cup serves as a seal to prevent any possible escape of gas from the tube 13.

Attached to the lower end of the tube 13 and below the plane of the several plates, when said plates are in normal or closed position, isa segmental plate 16, designed to be engaged by two of the plates to hold them in closed position, as indicated in Fig. 2. Ex-

tended partly around the frame is the resetting-rod 17. This rod hasits upwardly-turned ends connected to the hopper, as shown in Fig. Land it has a horizontal stretch 18 for a portion of its length and an upwardly-inclined or cam stretch 19 through a portion of its length. This resetting-rod is designed to be engaged, as will be hereinafter described, by arms 20, extended outward from the plates 10. The bell 14 is rigidly attached to the rod 12, and loosely mounted on the outer end of the rod is a pulley 21, carrying a pawl 22, designed to engage with a rack 23 on the upper side of the bell 14.

Arranged at one side of the generator is the gasometer, consisting of a fixed tank 24 and the bell 25. The bell is guided in its upward movements by rods 26, to the upper ends of which is connected at cross-bar 27, supporting pulleys 28 29. From the bell 25 a cord or chain 30 extends upward over the pulley 28, thence around the pulley 21, and back over the pulley 29, and the free end is provided with a counterweight 31, which serves to keep "the cord or chain taut.

From the generator a pipe 32 extends into the gasometer, this'pipe being provided with a cut-off valve and a petcock 34:. Leading from the gasometer is a service-pipe 35, provided with a petcock 36, through which dirt or sediment may be drained.

. As a means to permit the escape of gas should too great a supply be in the gasometer I employ pipes 37 38, the pipe 37 being connected to the bell 25 and telescoping over the pipe 38, the said pipe 38 being provided with a port or outlet 39 for discharging into the atmosphere. The pipe 37 is provided with perforations 40, through which gas escapes to pass into the pipe 38 when said perforations are raised above the level of the water in the gasometer.

As a means for agitating the sediment that may accumulate in the generator I employ a scraper or scoop 41, which extends transversely over the bottom of the generator at a slight upward curve. This scraper or scoop is attached to a rod 42, extended upward between the tank 5 and the hell 6 and having bearings in lugs 43, attached to the inner surfaces of the tank, the upper end of the rod being provided with an outwardly-extended handle 44. By oscillating the rod the sediment will be stirred up, so that it may escape with water through the outlet 45 at the bottom of the generator.

In the operation the carbid will pass from the hopper 7 through the spout 46 and fall upon one of the plates 10, that may be underneath the spout. It will be noted that the spout is at one side of the center or practically in a position to discharge oarbid at the center of each plate. As the gas is consumed and the gasometer-bell moves downward it will rotate the pulley 21, which, through the medium of the pawl 22 and the rack 23, will rotate the frame 9, carrying a loaded plate to a position to bring its inner end out of engagement with the plate 16. Then this loaded plate will tilt and discharge its carbid. The arm 20 of said plate when tilted upward will engage with the cam portion 19 of the resetting-rod. Of course at this time there will be another plate underneath the spout 46 to receive a charge of carbid. The generator gas passing into the gasometer will raise the bell 25, and the weight 31 will rotate the pulley 21; but as the pawl at this time slides over the ratchet there will be no back movement of the platecarrying frame. As the frame is again rotated the arm of the discharged plate will engage with the horizon tal portion 18 of the resetting-rod, holding the plate in its normal or closed position until its inner end again engages with the plate 16.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. In a gas-machine, a generator comprising a fixed portion and a bell, a carbid-hopper supported in the upperportion of the bell, a frame mounted to rotate below the hopper, a plurality of plates mounted to swing on the frame, means for rotating the frame, a segmental plate for supporting certain of the discharging-plates in elevated position, and

means for returning the plates to elevatedposition after discharging carbid.

2. In a gas-machine, a generator comprising a fixed portion and a bell therein, a hop-- per in the upper portion of the bell, a rod extended through the hopper, a frame attached to the lower end of said rod below the hopper, a plurality of segmental-shaped plates mounted to swing on the frame, a plate of segmental form for supporting the first-named plates, arms extended outward from the several plates, and a resetting-rod extended partly around the frame the said rod having a horizontal portion and an upwardly-inclined portion designed to be engaged by said arms.

3. 'In a gas-machine, a generator, ahopper arranged in the generator, a plurality of discharge-plates arranged underneath the hopper, a rotary frame on which the plates are mounted to swing, a rod extended upward through the hopper, a pulley on said rod, a gasometer, and a connection between said pulley and the gasometer, whereby the pulley is rotated to rotate the frame when the bell of the gasometer lowers.

4. In a gas-machine, a generator, a carbidhopper arranged in the bell of the generator, a tube extended through the hopper, a rod extended through said tube, a bell attached to the upper portion of said rod, a water vessel in which said bell is mounted to rotate, discharging devices supported on the lower end of said rod within the generator-bell, a pulley loosely mounted on the outer end of said rod, a pawl-and-ratchet connection between said pulley and the bell attached to the rod, a gasometer, pulleys arranged above the gasometer, a cord or chain attached to the gasometer-bell, and passing over one of said pulleys, thence around the first-named pulley and over the other pulley above the gasometer, and a weight on the free end of said cord or chain.

5. In a gas-machine, a generator comprising a fixed portion and a bell, a hopper carried by the bell, a plurality of plates below the hopper, the said plates being mounted to rotate and to swing vertically and independently one of another, means for successively releasing the plates, and means for returning the plates to carbid-receiving position.

In testimonywhereofl have signed myname to this specification in the presence of two subscribing witnesses.
