SPECIFICATION forming part of Letters Patent No. 493,085, dated March 7, 1893. Application filed February 16, 1892- Serial No. 421,733. (No modell).
To @ZZ whom t may concern,.-
Be it known that I, LESTER HALL, of Kansas City, in the county of Wyandotte and State of Kansas, have invented certain new and useful Improvements in Rocking Grates, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, which form a part of this specification.
My invention relates to the peculiar construction of a rocking grate, so as to afford a great amount of air space, to enable the operator to thoroughly agitate the surface of the grates, and for discharging the ash without wasting the live fuel; and my invention consists incertain features of novelty hereinafter described and pointed out in the claims.
Figure I, is a detail perspective view of a furnace with my improvements located therein. Fig. 1I, is an enlarged detail perspective view of a section of the grate showing the means for agitati ng or rocking the same. Fig.l III, is an enlarged perspective view of one of the fixed bars. Fig. 1V, is a perspective View of one of the rocking grates. Fig. V, is a perspective View 0f the adjoining rocking grate. Fig. VI, is a top view of the bracket into which the rocking lever may be inserted. Fig. VII, is an enlarged detail perspective view of the rocking lever. Fig. VIII, is a vertical transverse section of the rocking lever, bracket and bar which are situated at the'forward end of the furnace.
Referring to the drawings, 1, represents the lower portion of a double furnace to which my improvements are attached.
2, represents a series of horizontal independent bars or slabs, said bars resting at their rear ends on an angle iron 3, and at their forward ends on an angle iron 4, there being a ends of the bars and the front of the furnace. The bars 2, are provided with lateral end projections 6, which keep the same equi distant from each other, leaving a series of spaces 7, between said bars.
' 8, represents a series of pivoted grates formed in divisions. See Fig. I.
In the drawings I have shown two divisions of the series, as shown at 9, 10, one division for each side of the furnace. These divisions may be increased or diminished, or the numbers in the series increased or diminished without departing from the spirit of my invention.
The individual rocking bars or grates 8, are formed in substantially a T shape, having a flat surface l1, on their tops, and a-convex face 12, on their sides. The object in making the side faces adjoining or meeting each other on the rocking grates convex, is to make them conform to each other while being rocked, in order that the space between the same shall always remain approximately the same, without at any time increasing the opening between the meeting ends of the same, and thus preventing the waste of the live fuel. For instance, as one series of the rocking grate is moved from its vertical position to an inclined one one end of the T will be forced downward, while the adjoining end of the T in the next series will be forced upward, (see Fig. I) the space between the ends always remaining practically the saine.
The grate bars 8, are pivoted to the stationary bars 2, by means of rods 13, which pass through each member of the rocking grates 8, and stationary bars 2, as shown at 14E, thus pivoting them at their upper ends, the bar 2, being reinforced at the openings by bosses 15, extending downward from the top of the same, and the rocking grates 8, being reinforced throughout their vertical length by means of bosses 16. The rocking grates 8, are provided with 'pendent lugs 17, through which are holes v18, through which pass rods 19, connecting the same at their lower ends, each alternate section of the rocking grate 8, being provided with a boss 20, in order to keep the legs of said grates equi distant from each other. The legs of the rocking grates forming a division are connected to each other by horizontal bars 21, through which the rods19, pass.
22, represents a rod having its forward end extending out through the front of the furnace, as shown at 23, for the purpose of rocking the movable grates, said rod 22, being connected with the bars 21, as shown at24, by means of a clevis 25, to which it is connected by jam nuts 26.
27, represents a cross rod connecting the IOO `the center. lian ges 40, in the extension 37.
' through ftheenlarge'd opening 39.
that the enlarged head or l\boss`f12;may pass This is in order' to compel the `operator to alwaysre turn the rocking grates to a `level-position` before withdrawing the lever, as at this point thegrates `will present a level surface. f
244, represents lugs situated on either side of the stationary bars 2, said lugs being for thepurpose ot guiding the rocking grates 8,i `and preventing them from warping or other# wise being displaced. i
1. Thecombination ofa series of iindepend-j entiixed bars extending the full length ot the grate surfaces; a series'of rocking grates placed `intermediate of said fixed bars and `rods extending therethrough and through the fixed bars by which they are pivoted thereto,l said rocking grates `having downwardly ex tending legs, and rods for connecting the same;substantially as and for` the purpose set forth.
2. The combination of a series of independ ent fixed bars extending the full length of the grate surfaces;` aseries of rocking grates,y placed intermediate of said bars, downwardly?y extending legs on said rocking grates; rods extendingthrough the fixed bars and through the rocking grates; rods for connecting the legs of each series to each other, and bars through which said rods pass for connecting the series; substantially as and for the purpose seti-forth.
3. The combination of the independent IiXed bars 2 extending the full length of the grate surfaces, the rocking grates 3, placed intermediate of the same, and rods by which they are pivoted thereto, and lugs 44, on said bars 2, intermediate of the rods for guiding said rocking grate-s; substantially as and for the purpose set forth.
4. The combination of the xed bars 2, a seriesof rocking grates, the individual members forming one of a series of said grates, being connected by Irods 19; rods 13 by which the rocking grates are pivoted to the fixed bars, bars 21 for connectingfthe series, and a A rodl22, connectedwith one of saidxbars 21, for
oscillating the saineiin orderto rocksaid grates;A substantially `as and for theV Apurpose set forth.
5. 'llhecolnbination ofthe fixedlbars 2i, rocking bars or 'grates' 8, `placed* intermediate of the same andV pivoted thereto;-f.rds119,'aud bars 21 connecting said grates,="rodsi27, and `28, forming a Vbrace,.and connecting bars 21,
with Athe rod '22,and means for oscillating said barsg substantially as :set forth.
6.L'llhe combination of` a series of rocking grates suitably pivoted; bars `21;connected wwith the samep'a rod22 securedtoaclevis 25;

8. The combination, with the operating rod 22; ot the bracket36, providedwith` an extension 37ihaving` an elongated opening 38, enlargement 39, and ianges 40,' thelever 33 pivoted to the bracket, the clevis 31 by which the lower end of the lever is connected with the operating rod, and the removable lever 41 having an enlarged .lower end 4t2` provided withan opening l13 fitting the upper end of the lever;` substantially as described.
