AGETYLENE-GAS GENERATOR.

Specification of Letters Patent.

Patented Jan. 7, 1908.

Application filed May 12.1906. Serial No. 316,569.

' seat for the valve controlling the feed of can bid to the generating chamber.

With this object in view, as will more fully hereinafter ap ear, the invention consists in certain nove features of construction and arrangement of parts, hereinafter fully de scribed, illustrated in the accompanying drawings, and particularly pointed out in the appended claim, it being'understood that various changes in the form, proportions, size and'minor details of the structure may be made without departing from the spirit or sacrificing'any of the-advantages of the in-- vention.

The accompanyin drawin s represent a l an acetylene gas generator constructed in accordance with he invention. I

Similar numerals of reference are employed to illustrate corresponding arts throughout the several figures of the rawings.

The generating tank 10 is preferably cylindrical in form and is provided with a frustoconical upper portion 11 that is connected I bya throat piece 12 to a carbid chamber 13.

The throat-piece 12'comprises a short cylindrical section with a conical flange 12 on its lower end diverging from the opening 12 through the throat piece at suchan angle as to fitsnugly on the upper portion 11 of the generating chamber, The top of the throat piece hasa flat surface 12 surrounding the 'aforesaid opening which forms the seat for the valve 16. Surrounding theflat surface 12 is a divergent flange 12 for theirusto conical end of the carbld chamber 13.

Arranged within the carbid chamber is a cylindrical valve guide 14, closed at the top' to rotect the valve from the weight of the car id, and said casing is held in position by a plurality of wings or ribs 15, extended inward from the main wall of the casin The casing is arranged to contain a cylindrical ice pipe.

valve 16 that slides vertically within said casing, and is elevated to permit the discharge Of a quantity of carbid to the genere the lower portion of the gasometer is a pipe 20 from which extends a vertical pipe 25 that forms a guide for a pendent tube 26 that is secured to the gasometer bell, the tube and pipe forming a guide for the bell during its vertidal movement. of the tube is sealed by the Water in the gasometer tank, but when the uantity of gas is in excess of the capacity oi the gasometer, the tube will move'above the water line and the gas may escape by way of the pipe 25 through which it flows and a pipe 28 to a point of dischar e'that may be disposed any distance from t e gasometer. Gas flowing from the generator through a pipe 30 enters the gasometer from below and discharges thereinto through a suitable pipe above the water level in a manner well understood.

Extending through the top of the generat- 7 ing tank to a point below the water line thereof is atube 36 having at its lower end a bracket 37 to which is pivoted a lever 38. One end of the leveris connected by a rod 39 to the valve, and the opposite end is connected by a rod 40 to a lever 41. One end or the lever 41 is pivoted to a bracket or lug 42 pro jecting from the side of the carbid chamber or other fixed point, while the opposite end has a flexible connection 43 with the top of the g'asometcr bell, so that as the bell moves up, the rod 40 will be elevated by the fall of the valve 16 and rod 39 cutting off the sup ply of the" carbid. When the supply of gas runs low in the gasometer, the bellldescends, and this results iii downward movement of the rod 40 which is transmitted through V the lever 38 to the valve rod 39, opening the valve and allowing a charge of carbid to fall into the generating tank.

Extending transversely through Normally the lower end" The operation is entirely automatic," and as fast as the gas is consumed, fresh charges of arbid are admitted th the tank to generate the gas. At'the bottom of the enerating tank is 2i valved outlet 45, by w ieh the .slush and water may be drawn oi i, andat one side of the tank is a tube 47 extending nearly to the bottom of the'tank and serving as a ide for. the rod 48 that is provided at-its ower end with a slush agitating bar 49, and

at its upper endwith a handle 50 for operating the slush bar.

Attention is called to the fact that'the throat piece 12 is shown of heavier material than -the tank and carbid chamber 13. This throat piece is so shaped that the valve 16 contacts solely with it when closed and the structure is therefore rendered much more lasting than should the valve necessaw rily rest upon the sheet metal or other comparati'vely thin material of which the carbid chamber is formed. Obviously should the valve seat which is formed by the throat piece'become worn as-a result of long usage a new throat piece could'be substitut d at comparatively slight cost. I Havin thus described the invention, whatis claims is r.

In an acetylene gas apparatus, a generating chamber having a frusto conical upper portion, a throat plece of heavier. material than the tank or chamber with a conical fian e on its lower end diverging from a ver-.

tica o e'ning therethrough at such an angle as to t snuglyon' the frusto conicalupper portion of the generating chamber, a divergent flange on the upper end 'of said throat piece between which and the vertical opening is a flat valve seat formed by the top of the throat piece, a carbid chamber having a frusto conical bottom seated in the upper divergent flange of the throat closin' valve adapted to contro the flow of carbi from the carbid chamber to the generating chamber and disposed when closed to fixed part of the apparatus, said second rod movably engaging the slotted portion of said lever, and a gasometer having a vertically movable bell connected to the other end. of the slotted lever. Y

j In testimony that I claim the foregoing as my own, I have-hereto aflixed my signature in the presence of two witnesses.
