To all u om tvmayiconcem:

Beit known that I, HEINRIon KoPrERs, a

-citzen of the German Empire, and resident of 30 .Isenbergstrasse, Essen on the Ruhr, Germany, have invented a certainnew and useful Horizontally-Moving Leveling-Rod for Horizontal Furnaces, off-which the following is a' specification.

This invention refers to the construction of leveling rodsl for coke furnaces which overcomesand considerably reduces the known Yro `obiec'tion of the bending ofL the same, as the .free part, of the leveling rod is formed like a ladderwhoseside walls consist of flat bar.

irons standing on edge, the rungs. forming the actual leveling parts. This form of construction easily permits of forming the free part of the rod as a body of almost uniform resistance against bendings resulting from its own weight,'consequently with the least deilection, masmuch as the side Walls decrease in height towards the end. -Such a'body onlyr makes verv slight swinging movements.

This method of construction alsov permits of making the rodv at the spot-where it enters the furnace of a 'height which surpasses that of the remaining free s ace, inasmuch as the cross rungs which realy serve for leveling, are made-of such dimensions at these spots that they do not reachv to thel lower edge of the side walls, and consequently the leveling `is not eected as in the old construction, at

the height of the lower edge of the supporting rod but this plane is situated higher than the lattell. On withdrawing the leveling rod only the side walls cut into and remain in the charge of coal, but this is o f no importance.

I shall now describe my invention with reference to the accompanying drawing, in which, i

vFigure 1 shows in elevation a leveling rod constructed according to the present invention. Fig. 2 is a plan view'of Fig. 1. Fig. 3 is a vertical longitudinal section through the levelin bar, and Fig. 4a plan of Fi 3.

The Ieveling rod, formed from flat ar iron arranged on edge, and riveted cross rungs b,

' shafts c. l

is guided in a horizontal direction by the The leveling rod-s both for introducing and withdrawing as well as for the leveling movements are operated by the endless chain d which is held tightly stretched by the tension roller e. This chain d is moved the Wallys oven cut 'somewhat into the leveling plane; lno obstacle,

withdrawal of the leveling rod from the furby means of the sprocket wneelf in the one or the other directlon according as to whether the open belt g or the cross belt h is passed from the loose pulley i to the correspondingly fixed pulley 7c, which latter is rigidly connect ed to the sprocket Wheelf. Both these belts run over t e pulley Z which is maintained in constant rotation by the electro-motor o by means of the co -wheels m n. Thejintroduction of the rod into the furnace p is preferably controlled by hand; the Vreversing at the end of the stroke of the actual working movement is eiiected automatically,..in a

slmilar manner to the known planing Ina-y chine gear, by stops g, qstriking against the v belt guide r'. j

The partof the leveling rod projecting into "the furnace p is so formed that the flat bar irons a decrease in height towards the fref` end, Now the cross rungs or plates b are ef such dimensions' that their workin edge projects at the front endsof the eveling ro beyond the walls a, whereas inwardly draw back 'towards the same. The a consequently in the first half of the however, is thus formed to the nace, as on account of the inclination of the lower edge of the walls, on the backward movement they are immediately. lifted up from the coal.

l. A leveling rod for coke ovens, comprising a'pair of spaced longitudinal bars of gradua ly reduced height, and a series of connect- 'ing cross rungs that roject below the lower edges ofthe .bars at t e reduced ends thereof, substantially asspeciiied. Y

2. A leveling rod for coke ovens, comprlsing a pair of spaced longitudinal bars of gradua ly reduced height, and a series of connecting cross rungs which project below the lower.

lower edges of said bars at the reduced forward I ends thereof and are set back from said edges along the rear ends thereof, substantially as specified.
