Specification forming part of Letters .Patent No. 199,707, dated January 29, 1878; application led November 6, 1877. f
To all whom it may concern:
Be it known that we, NICOLAUs HENZEL, of- Prag, and PAUL WILHELM LrnBIcn, of Teplitz, Austria, have invented a new and lmproved Grate-Bar, of which the following is a specification This invention relates to an improved grate 'bar for furnaces in which a 4high degree of i slotted sides, all as hereinafter more 'fully described. i
In the accompanying drawing, Figure l is a top view, partly in section, of our improved grate-bar. Fig. 2 is a vertical longitudinal central section of the same; Fig. 3, a bottom view thereof, and Fig. 4 a vertical transverse section on the line x x, Fig. 1.
Similar letters of reference indicate corresponding parts in all the figures.
The letter A represents our improved gratebar. The same is preferably cast in one piece of metal, and is made of the usual long and narrow form, as shown in the drawing, but it may also be made annular or of other form.
It is provided at its ends, and may also be provided at its sides, with suitable prongs or cross-pieces a c, by which it is hung in the furnace in the customary manner. Aseries of such grate-bars, thus hung side by side, constitute the entire grate. i
The grate-bar A is made hollow and open at the bottom, as clearly `shown in Fig. 4. Its upper plate b, to wit-that part on which the fuel is placed, is provided from end to end with transverse oblique slots, arranged at preferably equal intervals, which slots exa tend to within a short distance from the edges of the grate-bar. Y
In this manner the top or part b is composed of a longitudinal rib at each side, said two `ribs being connected by transverse oblique knife-edged ribs, d cl, alternating with oblique braces g g, that extend farther downward than the ribs 0l, as shown.
The vertical sides e e, Fig. 2, of the gratebarA are also slotted similar to the upper side b, but the slots f in said sides are preferably slightly curved, as indicated in Fig.
2. The slots andthe ribs in the top and sides should bein line with each other, as indicated in Fig. 2.
g g are a series of parallel blades or braces, placed obliquely within the hollow of the gratebar A, and attached to the inner faces of the sides e e. We prefer to so space these blades that two slots, f, will be in each side e between every two pairs of said blades, as shown in the sectional part of Fig. 1; but a greater or less numberof blades may be used. The blades g are parallel to the ribs d, and are perforated at their upper portions, so that an air-passage is created directly below the top of the grate-bar through all the blades.
It will be seen that a grate-bar of the above construction supplies to the fuel a constant current of air. The air enters from below, between the blades g g, and also through the slots f in the sides c c, then passes under the top, and through the slots in the top, where it reaches the fuel, supplying the same with the necessary oxygen, and embracing the ribs cl so as to keep them comparatively cool.
As, by this construction, each grate bar supplies within the dimensions of its body the necessary fresh air for combustion, the gratebars constituting the entire grate may be placed close to each other, as the air needs not be supplied between the series of grate bars, as was heretofore usually necessary. The fuel will, consequently, not be apt to drop and remain suspended between the grate bars, at the saine time the ribs d d are placed close enough together that the fuel cannot fall between them or burn the sides of suchf` i This speeieation signed by us this the 7th ribs. Thus the fuel Will only be in Contact day of September, 187 7. With the surface of the grate-bars, and the same will therefore be less liable to Wear out NIKOLAUS HENZL.
. or Warp than those heretofore in use. vPAUL WILHELM LIEBICH.
We claim as ourinvention- The hollow grate-bar A, having diagon Witnesses: knife-edged ribs d, and diagonal perforated V. O. -GRIKRYLN, blades g, combined with the slotted sides e e, E, BRANDEIs. substantially as herein shown and described.
