BLAST-FU'RNAC E.

SPECIFICATION forming part of Letters Patent No. 594,577, dated November 30, 1897.

` Application led .Tnly 28, 1896. Serial N0. 600,764, (No model.)

To a/ZZ whom t may concern,.-

Beit known that I, MAXIMILIAN M. SUPPEs, of Lorain ,county of Lorain, State of Ohio, have invented certain new and useful Improvements in Blast-Furnaces, of which the following specification is a true and exact description, due reference'being had to the accompanying drawings.

My invention relates to certain improvements in blast-furnaces, and especially relates to the charging of the furnace.

As furnaces have been heretofore operated difficulty has been met in properly distributcharging-car hereinafter described. Fig. 3,

represents a side View of the charging-car. Fig. 4 shows a horizontal section through the car, and Fig. 5 is a vertical section ofthe same. Fig. 6 is the same section of the car, but in the position to discharge the load.

In a blast-furnace and the charging devices embodied in my invention there are preferably the following features: An elevator or skip-car for the purpose of elevating the several elements of the charge from the stockyard to a point above the top of the furnace, where the charge is transferred to a chargingcar. This charging-car travels upon a track passing directly over the bell of the furnace, and when it reaches this point the load is discharged into the bell, from whence it is dropped into the furnace. These being the general features, I will now describe my invention in detail.

Referring to Fig. 1, 1 is the furnace, the

top of which is closed by means of the bell 2. v

At a suitable point is the elevator or inclined railway 3, upon which is the skip-car 4:, adapted to elevate the material from the stockyard. This skip may be operated by any means, as the rope 5, and it is arranged to automatically deliver its load into the charging-car 6. This charging-car travels upon the track 7, Which passes from the deliverypoint. of the skip directly across the top of the furnace, so that when the charging-car is loaded from the skip it may be brought to a point directly over the center of the furnace, as is shown in the dotted line in Fig. 1. When it reaches this point, the load is dropped upon the bell 2 of the furnace.

The charging-car is constructed in the following novel manner: The frame S in Figs. 3 to G lis supported upon the wheels 9 and carries the cylindrical iiXed top shell 10. Be-

neath this shell is supported the conical bot- .are the rods 14, connected to the bail 15. At

a point to engage this bail when the car is central over the furnace is any suitable lifting device, as the hook 16,' operated by suitable power. (Not shown.)

When the car is in a suitable position to be emptied, it is necessary that the bail be upright in order to engage the hook 16, and when it is receiving the charge from the skip it should preferably be lying down out of the way. I providefor this in the following manner: Upon one end of the bail is the eXtension 17, projecting below the point of suspensionA and then extending' horizontally, as shown.

While the ear is to be under the skip the bail is down, but at the point of travel toward the furnace Where it is desired to raise it I place in its path bar 18, having its end inclined, as at 19. When in the course of travel of the car the arm 17 meets the incline, the bail is raised and maintained upright as it moves toward hook 16. It Will be understood IOO that while I have thus described the bail as movable it may also be fixed and remain at all times upright.

The bell 2 is operated by suitable means, as

the hydraulic cylinder 2O and counterweight 2l, acting through levers 22, yokes 23, and Suspenders 24. This construction is necessary in order that the charging-car may pass directly over the bell.

The operation of the several parts is as follows: The charging-car 6,which may be moved by any suitable power, is brought under the discharging position of the skip 4, and the several ingredients of the charge are emptied from the skip into it. It is then moved along the track 7, the bail 15, which was in the first place down, rising as it engages the bar 1S until the car is directly over the bell 2. The hook I6 now engages the bail 15, and by means of it the shell 13 is lifted so as to form an oritice around the bottom of it. charge to flow out into the mouth of the furnace, from whence from lowering bell it is dropped into the furnace. The shell 13 is I(hen lowered and the car moved back for another load. The distribution effected by the use of the conical bottom is verysuperior, the charge falling upon the bell very evenly distributed. This is a valuable feature, as even charging greatly increases the evenness of the output.

Having thus described my invention, what This allows thc I claim, and desire to protect by Letters Patent, is-

l. A charging-car for blast-furnaces, comprising a frame supporting a shell and a bottom member a distance below the shell whereby there is an opening between the bottom and the shell and a vertically-movable shell adapted to close the opening and open it for the discharge of the charge.

2. In a charging-car for blast-furnaces, a shell, a bottom, an annular orifice between the two and a vertically-movable shell adapted to close the orifice and open it for the emptying of the charge.

3. In combination with a charging-car ofthe class described, a bail on the operating member upon said car, a fixed stop adjacent to the track upon which the car runs and adapted to engage the bail and set it in the proper position.

In testimony whereof I have affixed my signature in presence of two witnesses.
