UNITED STATES FURMAN M. HANDLE, F ATLANTIC CITY, NEW JERSEY.
FURNACE GRATE.
applicati@ med August 1, 1927. serial No. 209,986.
The present invention relates to an improved furnace grate, and the purpose of the invention is to provide auxiliary grate members for use on the ordinary or usual grate bars, that is resting on and between them, whereby it is possible to burn a fine grade of coal, such as buck-wheat and rice coal in the furnace, enabling the ashes to pass through, and yet retain a substantial bed of hot coals.
In using the auxiliary grate members it is essential to use a blo-wer for sending a draft through the grate, and to assist in directing the draft upward and at the same time facilitate the passing of the ashes downward to the ash pit, the auxiliary grate members carry tins of elongated construction7 depending between the main grate bars.
These tins are in the form of blades extending the length of the auxiliary grate bars or members and are positioned between the main grate bars.
Another purpose is to provide auxiliary grate bars, which may be of the construction as in Figures 1 and 2.
It is to be understood that the particulars herein given are in no way limitive, and that while still keeping within the scope of the invention, any desired modification of de tails and proportions may be made in the construction of the appliance according to circumstances.
The invention comprises further features o and combination of parts to be hereinafter set forth, shown in the drawings and claimed.
In the drawings Figure l-is a plan view of a main grate of a furnace showing the auxiliary grate bars in position.
Figure Q-is a sectional view on line 2-2 of Figure l, through the frame of the grate showing the main grate and auxiliary grate bars.
Figure 3is a sectional view on line 3-`3 of Figure l. y n
Figure t-is a'pers'pective view of a por-y tion of a main grate showing an auxiliaryy grate bar resting on two of the main grate bars.
Figure -is a detail sectional view through Figure Ll.y
Referring to the drawings, 1 identifies a frame, which maybe any suitable construction and mounted for rocking movement therein is a plurality of main grate bars, Each main grate 'bar consists of a transverse bar or casting 3 withwhich a plurality of discs'or plates e are carried. These plates or discs may be integral with the bar 3 or mounted thereon in any suitable manner. Preferably the discs or platesa are integral with the bar 3.
In fact the bars 3 are adapted to rock in unison through the `medium of any well, known mechanism. `In `otherr words said bars 3 are interconnected by any suitable means notshown, sn that by the rocking movement of one bar 3, all the bars rock in unison, in which' case the discs or plates correspondingly move. Theidiscs orplates as` sume positions as shown in 'Figure 2, and resting on the edges of the plates tand betweeny adjacent series ofthe plate'sare auxiliary grate bars 5, which consist ofa plurality of relatively small discs 6, which are joined together by the interconnecting pieces 7. ln fact the auxiliary grate bars are in the form of castings, and as the main grate bars are rocked the auxiliary gratev bars roll back and forth 'between the edges of the plates 4 of the main grate bars, acting to agitate the coals andl thereby permit thek ashes to freely passtherethrough.
Depending from the series of discs 6 ofy the grate bars arey fins 8 which are inter posed between the opposed edges of the' plates 4 of themain gratebars.y These fins act as rbaffles to direct air from a blower upwardly through the grate, and at the same time they assist greatly in agitating and directing the ashes that pass between the main grate bars, and thereby facilitate the passage of the ashes. Adjacent where the fins 8 depend fromV the relatively small discs,
- the fins are cutaway as shown at 9, corresponding to ythe spaces betweenv the small discs, which also facilitates in agitating the ashes and facilitating their passage.
Referring to Figures 4 and 5 it will be noted that the fins 8 are eliminated, in which case the auxiliary grate bars simply rest on and between the adjacent edges of the plates j 4 yof the main grate bars.
with main rocking grate bars comprising pluralities of spaced disc plates, of auxiliary grate bars comprising pluralities of relatively small discs joined together,l the smaller discs resting edgewise to roll backwards and forwards on and between the edges of the disc plates of the main grate bars. t
2. In a furnace grate v the combination with main grate bars in parallelism comprising spaced disc plates, of auxiliary grate bars comprising relatively small discs spaced relatively closer together thanr the disc plates and restingto roll backwards and forwards on and between the edges of the disc plates and adapted to rock bachr andforth as the main grate bars are rocked. 3. In a furnace grate, the combination with main rockingl grate bars comprising pluralities of spaced disc plates, of auxiliary grate bars comprising pluralities of relatively small discs joined together, the smaller discs restingedgewise to roll backwards and forwards on andy between the edges of the disc plates of the main grate bars, andy depending longitudinal fins carried by the relatively small discs of the auxiliary grate bars, said ns being positioned betweenA the edges of the adjacent main grate bars, and acting to baflie the draft from a blower and direct the same upwardly between the bars.
4. In ayfurnace grate the combination with main grate bars in yparallelism comprising spaced disc plates, of auxiliary grate bars comprising relatively small discsy spaced relatively closer together than the disc plates and resting to roll backwards `and forwards on and between the edges of blower and direct the same upwardly be-.
tween the bars.
In testimony whereof he affixes his signature.
