Description
- UNIT -D STATES-PAT NT OFFICE FREDERICK VAN PATTEN AND GEORGE w. PERRY, OE AUBURN, NEW YORK.
IMPROVEMENT IN GRATE-BARS.
Specification forming part of Letters Patent No. 222,165, dated December 2, 1879; application filed July 17, 1879.
To all whom it may concern Be it known that we, FREDERIOK VAN PAT- TEN and GEORGE W. PERRY, of the city. of
Auburn, county of Cayuga, and State of New York, have invented certain new and useful Improvements in Grate-Bars; and we do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, in which-- Figure 1 is a side elevation of our grate-bar, showing its position in the furnace when in use. Fig. 2 is a plan view of the same, one of the fuel-supports being removed to show the retaining-lugs on the side of the bearing-bar. Fig. 3 is a side elevation of one end of the bearing-bar, with one of the intermediate fuelsupports, in dotted lines, inposition. Fig. 4 is a side elevation, partly in section, of one of the end fuel-supports. Fig. 5 is an end view of the same. Fig.6 is-a view of one end of the bearing-bar. Fig. 7 isan end view of one of the intermediatefuelsupports. Fig. 8 is a section of the bearing-bar on line 00 m, Fig. 3.
The object of our invention is to produce a grate-bar composed, essentially, of a bearingbar and removable fuel-bearings less liable to be destroyed by heat or use than those employed prior to our invention 5 and it consists in such grate-bar and the peculiar construction and combination of the parts composing it, as will be hereinafter fully described and claimed.
In the drawings, 1 is a bearing-bar, provided with a series of lugs, 2, two on each side of said bar, for each intermediate fuel-bearing,
for a purpose to be explained, said bar being preferably made of cast-iron. This bar 1 is provided with hook-shaped ends 3, for a purpose to be explained.
4 are end removable fuel-supports, and 5 intermediate removable fuel-supports, preferably made of cast-iron. Each of the end fuelsupports 4 is provided wi th standards 6 and 7,
forming intimate parts with the same. Each standard 6 has a perforation, 8, the upper and lower walls of which are inclined to receive and retain the hook-shaped ends 3 of the bearin g-bar 1. Each standard 7 is slotted to straddle and rest upon the bearing-bar 1.
, in gs.
The fuel- supports 4 and 5 are slotted, as
shown in the drawings, and an opening is made beneath them in each standard to allow a free circulation of air, and thus prevent their rapid destruction by heat and the conveyance gf much heat by conduction to the bearing- The hook-shaped ends 3 of the bearingbar 1 are inserted in the perforations S of the end fuel-bearin gs 4, and the standards 7 of the latter straddle and rest upon said bar in use,
the outer ends of said fuel-bearin gs 4 resting upon suitable ledges built in the walls of the furnace, as shown in Figs. 1 and 2 of the draw- The intermediate fuel-bearings 5 have their slotted standards 7 straddling and restin g upon the bearing-bar l and over their re spective lugs 2 on said bar. The bearing-bar 1 is thus hung so low down in the furnace that it is not liable to become warped or burned by the heat. The slotted fuel-bearings and standards provided with openings allow a free circulation of air, heat up the heat-currents, and thus prevent their rapid destruction and the transmission of heat to the bearing-bar.
The fuel-supports can expand and contract without any strain upon themselves and the bearing-bar, and the latter is also free to ex pand and contract without danger of warping or twisting.
When one of thefuel-bearings becomes worn out or burned, it can be readily removed and a new one substituted at small expense.
Having thus described our invention, what we claim as new, and desire to secure by Let ters Patent, is-- 1. The combination, in a grate-bar, of a bear ing-bar and end fuelsupports, which also support said bar, arranged, substantiallyas shown,
below them, substantially as described.
2. Fuel-bearings slotted and provided with standards having openings, substantially as described.
3. End fuel bearings provided with standards, one of which is slotted to straddle and rest upon the bearing-bar 1, and the other with a perforation to receive the hook-shaped end of said bar, substantially as described.
4. Intermediate fuel-bearings slotted substantially as shown, and provided with standards having openings, substantially as shown, and slotted to straddle and rest upon the bearing-bar 1, substantially as described.
5. The combination, with the bearin g-barprovided with lugs 2, of intermediate fuel-supports having standards slotted substantially as shown, to straddle and rest upon said bar over their respective sets of lugs, substantially as described.
6. A grate-bar composed, essentially, of end and intermediate fuel-supports, and a bearingbar supported by said end fuel-supports, substantially as described.
In testimony whereof We have signed our names to this specification inthe presence of two subscribing witnesses.
