GRATE BAR Filed Aug. 17, 1929 Fig. 2
Fig 3 [area/or rfieodo/vldolpb Jess en Patented Sept. 8, 1931 THEODOR ADOLlPI-I JESSEN, OF HUSUM, GERMANY GRATE BAR Application filed August 17, 1929, Serial No. 386,703, and in Austria October 27, 1928.
My invention relates to grate bars and it is an object of my invention to so design a grate bar that the circulation of the air through the fuel bee is improved.
To this end I provide on tne gra'e plurality of vanes which are directed ag the draught, and make the first rib rhoi than the other ribs.
In the drawings afiixed to this spociiisa tion and ferming part thereof, graie cinbodying my invention is illustrated diagrammatically by way of example.
In the drawings Fig. l is a cross section of two grate bars,
Fig. 2 is an elevation of one of the bars, and
Fig. 3 is a plan View of the two Referring now to the drawings, the bar (Z is provided with a tapered downwarc ly extending rib a which is equipped with lateral vanes Z) extending from the upper and widest part of the bar to the lower e-Ige of the rib a. As will appear i'rom 2, Ihe vanes b are so arranged that their lower ends are leading in the direction. of the draught which is supposed to come from the right in Jig. 2. They are preferably curved and reduced or pointed at their lower 0 ends. 0 is the first rib which is shorter than the other ribs, and it will be understood that by thus reducing the length of the first rib the draught is divided and deflected towards the front as well as the rear portion of the bar, and distributed uniformly throughout the length of the fuel bed.
As the ribs are reduced in thickness toward their lower ends the width of the passages between the ribs is conversely reducer toward their upper ends so that the velocity of the flow increases toward the upper ends of the air passages, and the upper parts of the grate bars will be cooled most intensely.
As the air is admitted to the fuel bed not in a Vertical but in an inclined direction, it is distributed uniformly and supplies an increased quantity of oxygen to the fuel bed without interfering with the space required for the movement of grate hooks or other implement.
fl au acen I wish it to be understood that I do not desire to be limited to the exact details of construction shown and described for obvious modifications will occur to a person skilled in the art.
In the claim affixed to this specification no selection of any particular modification of the invention is intended to the exclusion of other modifications thereof and the right to subsequently make claim to any modiiio0 cation not covered by the claim is expressly reserved.
I claim A grate bar having a body at its upper cud which constitutes a bearin surface and G5 is of uniform section throughout its effective length a tapered rib projecting downwardly from said body, and inclined vanes on said rib, one end vane being shorter than the others and the outer edges of said vanes being within the projected horizontal area of said body.
In testimony whereof I afiix my signature.
THEODOR ADOLPH J ESSEN.
