UNITED STATES PATENT OFFICE attain SLAG CONVEYER .i'oseph B. James, Salt Lake City, Utah Application August 28, 1934, Serial No. 741,865 I 1 Claim. (Cl. 193-11) This invention relates to an improved appaflattened formation 2| of the water delivery pipe ratus characterized principally by a conveyor in that it tends to flatten the stream or water and especially constructed for conveying slag to d to Spread it evenly Over e fi t bottom of a predetermined point of deposit by way of a the tro Also the toilet the trough is p suitable conveyer and water flotation process. to allow the attendant to remove clinkers and 5 The invention is expressly designed for use in obstructing particles before the suspended mass association with a blast furnace and is conf w er a d a e s t e p pe 8. structed for rendering the slag substantially Under s me conditions instead of introduc buoyant and depositing it in a flowing stream of Water through e op 9 in the end wall of water in the conveyor in a manner to conduct it t t it s t oduced 'in the manner shown 10 without undue obstruction to a point where it can 111 ure 7.

This leads to the conveyer carry it with a reasonable fall, or it may be belt or screw conveyor (not shown). At the pumped at any angle with slightly greater head intake end of the trough is a rectangular hole l9 pressure at the intake end of the trough, for inwhich is of a length equal to the width of the fiat stance, a pressure which would be sufiicient to bottom ll.

It is thought that persons skilled in the art to which the invention relates will be able to obtain a clear understanding of the invention after considering the description in connection with the drawings. Therefore, a. more lengthy description is regarded as unnecessary.

Minor changes in shape, size, and rearrangement of details coming within the field of inven-- tion claimed may be resorted to in actual practice if desired.

Having thus described the invention, what is claimed as new is:

Means for conveying slag from a furnace comprising an inclined chute having a considerable portion of its receiving end of channel shape in cross section with its top open and its bottom flat and the remaining part of the chute being of integral tubular form whereby the top of said remaining part is closed, said inlet end of the chute having a rectangular shaped opening in its upper extremity opening directly upon the bottom of the chute and which is of the same length as the width of the bottom, a. water supply pipe having a rectangular shaped outlet end connected to the chute and surrounding the opening, the bottom of the chute being plain to provide an even flow of the mixture of water and slag over the same, and means for discharging the slag into the channel part a slight distance below 15 the water inlet opening.
