Definitions
- the invention relates to a locomotive grate structure of the general type disclosed in my U. S.
- the unbafhed draft air passing through said straight-draft openings would carry burning fuel from the grate through the locomotive flues and stack, not only wasting .i'uel but causing slagging of ilues, and cinder cutting.
- the present invention aims to so improve the grate finge-r of' the aforesaid nt as to overcome the above discussed dimand extended use of ylocomotive grates ving the improved ngers, has proven that the ed end has Ybeen attained.
- each grate section includes separate fingers on a finger bar, it is to be understood that the improvements are equally applicable to a unitary grate section.
- Each grate 'section in the present disclosure comprises a finger bar II) and a plurality of 1ingers ll mounted thereon, the pivots of the finger bars being denoted at I2.
- These finger bars are provided with the usual downwardly projecting arms I3 which are pivoted to the conventional shaker rigging it.
- Each 'finger lI comprises an enlarged head l5 extending longitudinally of the upper edge of a vertical web I6, and said head consists of a longitudinal'ridge Il and ribs I8 extending longitudinally of the lower portion of said ridge.
- the ridge lll is centrally located andthere are two .of the ribs'it projecting laterally from the plis-.hed by reference to the accompanying drawings.
- Figure i is a fragmentary top plan view showing a grate constructed in accordance with the present invention.
- Figure 2 is a vertical longitudinal sectional l view on line 2-2 of Fig. l showing the grate secopposite sides of ⁇ said ridge.
- the ribs I form the bottoms of airconducting valleys I 9 between the fire-supporting yridges I1.
- the valleys I9 have suitable air inlet openings or tuyres 20 lwhich baffle and diffuse the draught air drawn through.
- the grate under the infiuence of the locomotive exhaust, and the fire-supporting ridges Il are formed with transverse air-conducting channels ZI. Everything so far described is disclosed in the above mentioned patent.
- each finger head I5 consists' of an upper half lle disposed substantially in a ltransverse plane inclined in one direction, and a lower half lll disposed substantially in a second transverse plane Vinclined in the other direction, said upper and lowerr halves converging to a transverse horizontal ridge line 23 at the extreme end of said head I5.
- the end walls 22 at opposite sides of the ridge Il extend upwardly from the ribs i8 to the ridge line 23 and the outer transverse sides of these walls form portions of the inclined lower half I'Ib of the above described end surface of said head I5.
