JAMES N. LONG, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR OF ONE- HALF PO` DAVID COULTER, OF SAME PLACE.
G RATE.
SPECIFICATION forming part of Letters-Patent No. 309,789, dated December 23, 1884.
Application filed April 2, 18811. (No model.)
T0 all whom it 71u11/ concern:
Be it known that I, JAMEs N. LONG, a citizen of the United States, and a resident of Philadelphia, Pennsylvania, have invented certain Improvements in Grates for Stoves and Furnaces, of which the following is a specification.
The object of my invention is to construct a simple form of combined shaking or agitating and dumping grate, and this object I attain in the manner hereinafter set forth, reference being had to the accompanying drawings, in Which- Figure 1 is a longitudinal section of part of the tire-place of a furnace with my improved grate; Figs. 2, 3, and 4, transverse sections of the grate-ring with the bars in elevation; and
Fig. 5, a sectional plan on the line l 2, Fig. 1.
A is the casing of the furnace, B, the ashpit; D, the dre-pot, and w the lire-brick lining of the latter, supportedupon a iiange, a, in4 the casing.
The grate comprises an outer ring, F, and
a series of bars, G, hung to the'outer ring by' front and rear truunions, b b d, each bar having ou the bottom projecting lugs f, which are connected together by a bar, g, pivoted to each lug, so that all ofthe bars are compelled to rock in unison when one of the bars is actuated. The ring F has a rear trunnion, 7L,
adapted to a bearing in a lug, fr', on the flange a., but the front trunnion, b, of the central bar of the grate is larger than the others, projects through the ring F, and is adapted to a bearing in a lug, t, so as to form also the front trunnion ot' the ring, the outer end of this trunnion being squared or otherwise constructed for the reception of a suitable tool whereby it may be rocked in`x its bearing. A pin, on, serves to look the ring F to the casing when it is not desired to dump the grate, in which case rocking of the trunnion b of the center bar, G, simply causes the tilting of the bars of the grate, as shown in Figs. 2 and 3; but when itis desired to dump the grate the pin m is removed, whereupon after the bars have reached the posit-ion shown in Fig. 2 further movement will be transmitted to the ring F, which will swing on its trunnions, as shown in Fig. 4. On the reverse movement a lug, n, on the flange a serves to stop the ring when it reaches a horizontal position.
I am aware that grates having bars trunnioned in a tilting ring are not new; but I am not aware that any grate of this character has been proposed in which a single trunnion serves both for the outer ring and the centra-l bar of the grate; hence I claim as my invention- The combination of the ring F, having a rear trunnion, 71, with the bars G, trunnioned in the ring and connected together, as described, the front trunnion, b', of the center bar projecting through the ring and serving as a truunion for the same, as set forth.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
JAMES N. LONG.
