This invention relates to links for furnace grates and more particularly travelingchain grates. 1
The main obj ectof my invention is to provide the links with overlapping sideflanges to prevent droppage siftingv through the grate yet allow draft to pass through the.
same to sustain the fire thereon.
fr turther ob ect of my invention 18 to have there flanges so arranged that they may have movement relatively to each other to discharge the droppage therefrom as the links follow around one end of the. grate.
The invention consists further. in thematters hereinafter described and more particularly set forth in the appended claims.
In the accompanying drawings Fig. 1 is avertical longitudinal sectional view taken through the rear or tail end of an endless chain grate made of links of my invention v Fig. 2. is an enlarged side elevational view ota number of said links arranged as'in said r r Fig. 3 is a bottom plan view of the links in Fig; 2;
F1g.- i is a. transverse vertical sectional view taken on line e l of Fig. 2; and
Fig. 5 is an end view taken of alink.
Thev links. of my invention arejindicated by 1 and all are'alike so'that a description of one will sui'h'ce for all. Each link 1'. has a main body portion or web 2 laterally narrow and extending from end to end of the link. The web 2 is uprightwhen the link is in a grate structure. The upper end of the web 2 terminates in a larger or head portion 3, which is the fuel supporting part of the link when in the grate structure. This head portion 3 extends the full length of the link and projects outward on opposite sides of said web 2., as shown in Fig. l.
Below the head portion 3, the web 2 is provided on each side with outwardly projecting flanges 4i, 5, 6, 7. These flanges, on each side or the link,are arranged with the flanges l and 7 inclined downward and inward toward each other and at opposite ends 01 the link, while the flanges 5 and 6 are between them. The latter meet at their upper ends and diverge downward toward the associated end flanges a and 7, respectively, as shown in 2.
The end flanges 4t and 7 and their associ ated mid-flanges 5 and 6, on each side of the link, terminate in circular bosses 8, 9, which define cyhndric holes or bores '10, ll through the web 2 adjacent the ends thereof. These bores are made to accommodate link supportingrods 12, 12 oflthe grate structure. The lower edges or the webs 2at the front and rear ends of thelinks are shaped'to follow around the bosses 8,v 9 and thus provide spaces for the teeth of the sprocket wheels used to drive the grate.
When assembled to provide the grate structure shown in Fig. 1, the links 1 are arranged in rows extending lengthwise of said structure. The links in each row are in encwise alignment and each link is mounted on two rods 12, 12,]as shown in Fig. 3-. The links in' adjacent rows are in staggered relation, so thatbreak joints are provided at the ends of the=links, as shown in Fig. 3. This makes the rods 12 'at the front and rear ends of a link'in one row support'the rear and'front ends, respectively, of the links" in the adjacent rows on opposite sides thereof.
The flanges 5 and 6 of each link are in line, with the centers otthe adjacent bores 10, 11, as indicated bythe dotted lines a, b in Fig. 2. The end flanges 4: and 7 0i? each link are ofl'set above these centers, as'shown byfdotted lines' opal-in said figure. Bythe staggered relation" ot the links, the end flanges'dandi? of oneilink are adjacent the mid-flanges i -and G QrespectiVe'ly, of the links on" opposite sidesthereot, and by the ofl'setting mentioned, these end flanges are above the mid-flanges, as shown in Fig. 4t. As there illustrated, the'said flanges 5 and 6 extend outward from the webs 2 a greater distance than the end flanges l and 7, with the result that the latter are overlapped by the former and prevent droppage sitting through the grate. Said flanges catch droppage after passing between the heads 3, 3 and, by moving relatively to each other-as the links turn over the tail end 01" the grate, dump or discharge the droppage over such end of the grate. These flanges being oflset or spaced above each other in the manner described, allow draft to pass upward through When in chain grate form with upper and lower leads or runs, as shown in Fig. 1, these links 1, 1 prevent droppage sifting through the upper lead onto the lower lead.
This avoids the use of droppage collectingmeans or floors associated with the lower leads, as heretofore, Thus, with the drop-f page collecting means embodied in the links themselves, separate and additional expensive means for this purpose, as heretofore used,is avoided, with the attendant saving in material, structure and cost of operation.
- laterally spaced apart, each link having outwardly projecting inclined mid and end flanges on opposite sides of its web and disposed below the fuel supporting portion.
thereof, certain flanges of the links of alternate rows projecting over flanges of the links of intermediate rows to prevent fuel sifting through the grate and being vertically spaced for the passage of draft between them, said links each having rod receiving openings between the mid and end flanges thereof.
2. A grate link of the character described,
' comprising a web having an enlarged upper edge forming a head, inclined mid and end flanges projecting outward from a side of said web below said head, said inidflanges projecting outward farther than said end lapping in the spaces between the links below the heads to prevent droppage sifting through the grate, said links having holes therein and provided with outwardly projecting tubular bosses around the same, and
rods extending through said holes for connecting the links, said bosses being between the end and mid flanges with the adjacent ends. of said flanges terminating in said bosses, the links in one row beingstaggered withrespect to the links in the rows on op-- posite sides thereof andarranged with the end flanges abovethe mid flanges on links of adjacent rows.
4. A grate link of the characterdescribed, comprising a web having an enlarged upper edge forming ahead, inclined end and mid flanges on opposite sides of said web below said head with the mid-flanges projecting outward farther than said end flanges, said web having two' holes therein between the adjacent ends of said end and mid-flanges, tubular bosses on said websand surrounding said holes with the end and mid-flanges terminating therein, said flanges being so disposed that extensions of the end flanges would pass above the centers of said holes and extensions of the mid-flanges would'pass through said centers.
In testimony that I claim the foregoing asmy invention, I aflix my signature, this 20th day of January,'A. D. 1923. I
