. W. A. VIETOR GRATE BAR Filed Oct. 19
Patented Apr.. l?, 1923.
liwdd@ WILLIAM AUGUST VIETOR, OF EITREKA, CALIFORNIA .l
GRATE BAR.
Application filed. October 19, 1922.
T o au 'whom it may concern:
Be it known that l, WILLIAM AUGUST Vin'ron, a citizen of the United States, residing at 268 Hillsdale St., Eureka, in the county of Humboldt and State of California, have invented a new and useful Grate Bar, of which the following is a specification.
ll`he device forming the subject matter of this application is a furnace grate bar, and
the invention aims to provide a device of the sort above mentioned which will be well adapted to burn saw dust and mill refuse, the bar embodying a single detachable top plate, extended in a single length from one end of the bar to the other, the openings in the top plate being so located that the bearing bar which supports the top plate will be protected from the lire, no holes bein directly over the bearing bar, the
20 bearing bar being so constructed that air may be admitted beneath the top plate, means being provided whereby the top plate will be prevented from having vunnecessary movement on the bearing bar, it
being possible, nevertheless, for the top plate to expand and contract, the bearing bar being wedge-shaped at one end, so that it may enter the ashes on the grate frame, when the bar expands, the holes in the top plate being so constructed that they will clear themselves readily from dirt.
It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the invention appertains.
With the above and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that, within the scope of what is claimed, changes in the precise embodiment of the invention shown can be made without departing from the spirit of the invention.
In the drawings Figure 1 shows in side elevation, a device constructed in accordance with the invention, parts being broken away and parts appearing in section; Figure 2 is a top plan wherein the upper plate is broken away Figure 3 is a cross section on the line 3-3 oi Figure 2.
rThe device forming the subject matter of this application vcomprises a bearing bar Serial No. 595,594.
denoted generally by the numeral l and including sides 2 an end 3, an end 4 and a partition 6 connecting the sides 2 at a point intermediate the ends 3 and 4. A top plate 7 rests on the bearing bar l and is extended in a single length from one end oit' the bar to the other, the top plate being provided with openings 8 disposed out of alinement with the sides 2, the ends 3 and 4 and the partition 6, inorder to prevent these portions of the bearing bar l Jfrom being burned out. The openings 8 are downwardly flared, as shown at 9 so that they may clear themselves readily of ashes. The top plate 7 is provided with depending lugs l0, located on opposite sides of the partition 6. The lugs l() cooperate with the partition 6, to prevent undue longitudinal movement of the top plate 7 on the bearin bar l. The lugs l() cooperate, also, with t e sides 2 oi the bearing bar, to prevent the top plate 7 from shifting transversely to an undesirable extent. The lateral movement of the top plate 7 islimited, also, by depending lugs 25 on the top plate, adapted to cooperate with the sides 2. Depending lugs l1 are carried by the top plate 7, these lugs being located in certain of the corners formed by the sides 2 and the ends 3 and 4 of the bearing bar l, the lugs ll serving to prevent the top plate 7 from shifting to an undesirable extent either longitudinally or transversely. All of the lugs 10, 11 and 25 are spaced suiiiciently from the bearing bar l, so that the top plate 7 may expand and contract. Notches l2 are formed in the sides 2 of the bearing bar l beneath the top plate 7, and notches 14 are formed in the upper edges of the ends 3 and 4 of the bearing bar 1. The notches 14 and 12 admit air beneath the top plate 7. The partition 6 has a notch 15in its upper edge, which facilitates the circulation oi air beneath the top plate 7. One end of the top plate 7 is beveled as shown at 16 and the end 4 of the bearing bar l is correspondingly inclined, as shown at 5, thereby giving the grate bar, at one end, a wedge-shape, whereby the grate bar will enter readily into the ashes on the bar supporting frame, when the grate bar'expands.
What is claimed is ln a device of the class described, a bearing bar comprising sides, ends, and a partition connecting the sides, and a top plate resting on the bearing bar vand extended in a single length from one end oli' the har to the other, the top plate having openings disposed out of alinement with the Sides, the ends, and the partition, the top plate being supplied with depending lugscooperating` With the bearing bair to limit the movement of the top plate, the lugs being spaced from the bearing bar sufficiently so that the top plate can expand and `contraet, the bearing bar being provided in its upper edge with air-admise@ nothee on@ @ed of the beering bal' being downwardly and outwardly inclined, and the coi'esponding end of the top plate beinginclined to cooperate with the Slope of Said end of the bearing bar.
In testimony that claim the foregoing as my own, have helvetoeaflixed my signature in the presence of tivo Witnesses.
