ALLAN CHESMAN GRANT, OF ST. GEORGE, NEW BRUNSWICK, CANADA.

ACETYLENE-GAS' GENERATOR.

Specification of Letters Patent.

Patented May 36 1911.

Application filed August 29, 1910. Serial No. 579,434.

T 0 all whom it may concern:

Be it known that I, ALLAN OHESMAN GRANT, of the town of St. George, in the Province of New Brunswick, Canada, have invented certain new and useful Improvements in Acetylene-Gas Generators, of which the following is the specification.

My invention relates to acetylene gas machines, and the object of the invention is to devise a simple machine in which the feed valves will not clog through slack adhering to them and in which such valves will be positively closed to cut off the feed of the carbid.

It consists essentially of an outer tank, an inner casing supported within the tank by suitable hangers depending from the sides of the tank, a tubular neck extending upwardly from the casing to the interior of which the neck communicates, a carbid holder provided with a conical bottom depending into the neck, feed valves pivotally secured to the outside of the carbid chamber in proximity to the depending apex located within the tubular neck of the inner casing, a toggle joint connection between the pivoted valves and the wall of the tubular neck, a float located in the casing and hangers connecting the toggle joint connection to the float as hereinafter more particularly explained.

The drawing represents a vertical section of my machine.

A is a tank designed to contain water.

B is an inner casing supported within the tank A by depending hangers B, which are secured to the inside of the wall of the tank A in proximity to the top thereof. The hangers B extend downwardly in an oblique direction and are suitably secured to the bottom rim of the inner casing B. On referring to the drawing it will be seen that the casing B has an open bottom.

G is a tubular neck extending upward from the top of the inner casing to the interior of which it communicates.

D is a carbid receptacle provided with an inverted conical bottom D extending down and fitting into the tubular neck C.

D are feed openings located in the bottom D in proximity to the apex thereof.

D are castings secured to the bottom D of the carbid receptacle D and provided with feed openings D registering with the openings D D are lugs forming part of the castings D D are valves pivotally connected to the lugs D by pins D D are brackets secured to the inside of the tubular neck C.

D and D are links pivotally connected together by a pin D and to the valves D and brackets D by pins D and D respectively.

F is a float located in the receptacle B.

F are link rods secured at their lower ends to the float F and are provided at their upper ends with forked castings F extending to each side of the links D and D and through which the pins D also pass.

J is a pipe leading from the neck C through and around the bottom of the easing B into a supplemental water chamber J.

J is a depending tube having a closed upper end and into which the tube J extends above the water level in the chamber J.

I is a pipe leading to the service pipe H. The gas in passing through the water in the chamber J is cooled at it passes to the service pipe.

K is a gage rod by which the depth of the carbid in the carbid holder is indicated.

G is a blow out pipe.

G is a branch pipe connecting the blow off pipe with the interior of the tubular neck 0. The tubular pipe G is provided with a closing valve G H is a service pipe which is provided with a suitable filter H located at any suitable point in its length. The filter H comprises a tubular casing filled with felt or any other suit-able filtering material.

H is a drip pipe.

Having described the principal parts involved in my invention I shall briefly describe the operation of the same.

It will be understood that the casing B and necks 0 form the gas generating chamber. As the gas is fed through the service pipe H the pressure in the casing B is necessarily reduced allowing the water contained in the tank A to rise within the casing B. The water continues to rise untilit lifts the float F. The lifting of the float F breaks the toggle joint formed by the links D and D, the float being connected to such toggle joint by the link rods F as hereinbefore described. By this means the valves D are swung away on the pins D from the openings D thereby allowing the carbid to feed through the openings D and D into the generating chamber. It will also be understood that as soon as the gas pressure increases the water contained in the casing B will be forced downward carrying with it the float F. Immediately the water has left the float F the full weight of the float will serve to spread the toggle joint links D and D apart so as to bring them into alinement and thereby swing the valves D into their closed position.

From this description it will be seen that I have devised a very simple machine in which the feed valves are not liable to become clogged and in which no springs or gaskets are employed, which are liable to wear out or otherwise be deleteriously affected.

lVhat I claim as my invention is:

1. In a device of the class described, the combination with a carbid receptacle having an inverted conical bottom having :teed openings in proximity to the bottom thereof, and a hollow neck supporting the carbid receptacle, of pivoted valves located in proximity to the feed openings, brackets secured to the inside of the neck, toggle jointed links connecting the valves with the brackets, a float and connecting means between the float and toggle jointed links designed to break the joint upon the rising of the float, as and for the purpose specified.

2. In a device of the class described, the combination with the carbid receptacle having a vertical conical bottom, having feed openings located in proximity to the apex thereof, of castings secured to the said bottom having feed openings registering with the feed openings in such bottom,bearing lugs forming part of the castings, valves pivotally connected to the lugs, suitably supported brackets, toggle jointed links between the brackets and the valves, a float, and links connecting the float with the toggle jointed links designed to break the toggle by the raising of the float, as and for the purpose specified.

ALLAN OHESMAN GRANT. lVitnesses:

CHARLES J OHNSON, W. F. MORIN.
