- .'I'he Schedule referred to in these-Letters Patent and part of the same.
To all whom it may concern: I
Beit known that -I, J ESSE REYNOLDS, of the city of 7 Philadelphia, in the Stateof Pennsylvania, have invented a certain' ,newand. useful Improvement on Grate-Rests or Bearing Bars; and I do hereby declare that the following is a full, clear and exact description of the construction and operation of the same, reference being had to theaccompa-nying drawings, and to the marks andletters thereon, which said drawings form part of this specification, and show a grate with my improvement as-a part thereof-.-
Figure l being a topgv'iew' of the grate; Figure'2, a viewby vertical section of; a draw-bar; and
Figure 3,,a view of the bearing-bar, shown detached from the grate. i
In each of these figures, when like parts are shown, like marks and letters are used to indicate the parts. In many instances,it is quite important that the bars of .grates for furnaces or heaters should be so constructed and arranged asto allow of suchmovements aswill permit the fire a be raked, and partly or wholly withdrawn from the surfaces of the bars and furnace. i
An invention'having this object in View, was made the subject of Letters Patent, which weregranted to me, and bear date on the 9th day of July, 1867.
The present invention has reference 'to' this patented invention, and is of-the character of an additional improvement thereto, although not limited in its application and use entirely to the firstnamed invention, I I Asv is shown by the. drawings herewith filed, the grate-surface is made up of flat bars a, and round bars b, suitably arranged within the grate-frame c. i i -The round bars 11 are commonly known as drawbars, and are used for the purpose of clearing the firepot of cinders, 8m, whilethe-fire is hot, by drawing them out and removing the cinders, 860., through the space left after they are withdrawn, andalso of emptying the fire-pot or cleaning itwheni'resh fire is to be made, and without removing the other grate-bars.
It generally is the case that whenthese bars are removed ,while the fire is hot, or become withdrawn from the holes in the bearing-barsd, made to hold their ends while raking with a poker, or in any other manner become dislodged, it is exceedingly difiicult to put them in'place, especially when the weight of the coal in the fire-pot is on them; and in many cases it is necessary-to empty the fire-pot, in order to replace the ends of the draw-bars.
Now, my present improvementis intended to obviate the-difiiculties above named; and I do this'by attaching a piece of metal, 0, to that part of the rest where the bars slip in, tapering it gradually'from' the bottom of the holes to a point much lower than the bottom of the draw-bars, when in their proper place. A section of the fire-pot,with the the draw-bar in place, is shown by fig. 20f thedrawings,-the rest or bearing-bar being indicated by the red lines, and the draw-bar by black lines.
Now, if the bar be removed, as isshown by the red lines 1; by pushing or striking on the outer end y, it readily and immediately slides up the incline surface it into its place, and on the principle of the wedge, raises any coal" or material that may impede its way. This projecting piece 0 may be made of any desirable length or. inclination, and may be made along the whole' length of the bearing-bars, so that the grate may be all of draw-bars.
If necessary to get the barin p1ace,"shou1d it be drawn out past the end of the projecting piece, all that will be required, is to place its end'upon the end of the inclinean operation in no way whatever diflicult to be performed-and by a blow, or by pushing thedraw-bar, force its end up the inclined surface.
What I claim as my invention, and desire tofsecure by Lettcrs'Patent, isg The combination and arrangement of the tapering or wedge-shaped piece 0 with the bearing-bars d of :the grate, and sliding bars b, whereby the bars may be. pushed up to their places, substantially as described.
This specification signed, this 19th day of January,
