ATENT GEORGE O. TUPPER,
OF NEW YORK, N. Y.
FURNACE GRATE-BAR. g
To all whom it may coneem:
Be it known that I, GEORGE O. TUPPER, of the city, County, and State of New York, have invented a new and useful Improvement in Furace Grate-Bars; and I do hereby (leclare that the following is a full, clear, and exact description hGI'GOf, which Will enable others skilled in the art to make and use the same, reference being had to the accompanying drawing-s, forming part ot' this specitication, in which Figure l is a perspective View of my iniproved grate-bar. Fig. 2 is a top View of the same. Fig. 3 is acrosssectiou of the same taken through the line x x, Fig. 2.
My invention has for its object to Furnish an improved grate-bar for furnace-grates, simple and cheap in construction, and which will be protected against vertical pressure or lateral warping from the effects ot' heat; and it consists ot' a grate-bar the rib or lower part of which is corrugated longitudinally with one or more corrugations on each side, as hercinalter nore 'ully described.
A is the grate-bar, the upper surface and ends of which are constructed in the ordinary manner. a' are lugs formed upon the upperside edges of the bars A. These lugs to' rest against similar lugs on the sides of the adjacent bars, and they should be ot' a size proportioned to the size ot' the grate and to the size of the required space between the bars. The number of these lugs on each side of the bar will also depend upon the size ot' the grate in which the bars are to be used.
One great difficulty attending the use of grate-bars arises from the et't'ect of heat, causing the bars to warp or spring laterally. This difficulty has been sought to be remedied in various ways, but the most of the bars constructed for this purpose have been too complicated in their structure to answer a good purpose, and too costly for general use.
lt is well known that if thesame amount of metal is made into two bars, the one plain and the other corrugated longitudinally, the corrugated bar will sustain much the greatest pressure. For this reason I make the rib or lower part, a of the bar with one or more longitudinal corrugations on each side, as shown in Figs. 1 and 3. By this Construction, without using so much metal as to make the bar cunibersome or to diminish the draft, I obtain a bar of sufficient strcngth to resist downward or lateral pressure, whether from the weight of the fire or the eft'ect of the heat, or from both combined, and thus obtain a grate-bar light and simple in Construction and of great dura bility. lt may be observed that in the construction of grates for large furnaces two or more of these bars A may be placed end to end in the ordinary manner.
lVhat I claim as new, and desire to secure by Letters Patent, is
As a new article of manufacture, a furnace grate-bar the rib or lower part of which is corrugated longitudinally with one or more corrugations on each side, substantially as herein described, and for the purpose set forth.
The above specification of my invention signed by me this 9th day ot' February, 1866.
GEO. O. TUPPER.
