Description

UNITED STATES PATENT OEEIcE.
MICHAEL HELBLING, OF ALLEGHENY GITY,PENNSYLVANIA, ASSIGNOR TO HIMSELF AND' JOHN F. MGKINNEY, OF SAME PLAGE.
IMPROVEMENT IN GRATE-BARS.
'Specification forming part of Letters Patent No. 87,564, dated March 9, 1869.
To all whom it may concern:
Be it known that I, MICHAEL HELBLING, of Allegheny Oity,in the county of Allegheny and State of Pennsylvania, have invented a `new and -useful Improvement `in Grate-Bars;
and I do hereby vdeclare the following' to be a full, clear, and exact description thereof, reference being had to the accompanying drawing, making'a part of this speciiication, in which- Figure l is a perspective view of my improved, grate-bar, and Figs. 2 and 3 are side views of molding strips or patterns used in i making the mold when a bar is required of less secured, and at the same time a bar is made of more than usual strength and durability.
To enable others skilled in theart to make and use my invention, I will proceed to describe the same.
A is a grate-bar or grating for a furnace, molded and cast in the usual way. In form it consists of two side or main ribs, a a', of sufficient vertical depth to secure the required strength, of ends b b', and of cross-ribs c c, the latter running, as shown, diagonally across from onefside, a., or end b, to the other end, b', or side a', or vice versa.
It will be observed that the diagonal ribs 'o c intersect each other so as to leave square or diamond shaped apertures d for the admission of air tothe fuel. The size of these apertures d, as well as the thickness of the diagonal ribs c, may be varied at pleasure.
The upper faces of all the ribs are guttered I or grooved, as at s, so that, such gutters or grooves being iilled with ashes, the faces of the ribs themselves will be, in part, protected against the destructive action of the fire above.
0n the outer faces of the side ribs a a cars e are cast, by which the desired apertures between bars are preserved. v The grating described rests by its ends b b on properly-shaped bearings.
Among` other advantages I claim an easily and cheaply cast and durable bar, having the required strength, and not liable to be broken or warped by the expansion and contraction resulting from a high degree of furnace-heat, especially since such expansion and contraction will be uniform in all directions.
I am aware that grate-bars have been made with short cross-bars projecting from the main bar and connected at their ends 5 but such bars are liable to warp and sag-an objection which is obviated by my improvement.
I am also aware that web-shaped gratings have been used; but such gratings lack the side ribs described, which are essential to my improved grate-bar.
What I claim as my invention, and desire to secure by Letters Patent, is-
A reticulated. grate-bar or grating for furnaces vconsisting of side ribs a a', ends b b', and diagonal cross-ribs c, intersecting each other, substantially as and for the purposes hereinbefore set forth.
In testimony whereof I, the said MICHAEL HELBLING, have hereunto set my hand.
MICHAEL HELBLING.
