Filed Sept. 28, 1951 Patented May 1, 1934 PATN GFFICE COAL HOD Gustaf Daln, Stockhohn, Sweden, assignor to Svenska Aktiebolaget Gasaccumulator, Stockholm, Sweden Application September 28, 1931, Serial No. 565,656

10 Claims.

My invention relates to coal hods or filling buckets for coal, coke or the like, and more particularly to coal hods for filling coal, coke or the like into a magazine of a stove, such, for example, as shown in U. s. Pat. No. 1,817,712, to

J. G. Scheer, granted August 4, 1931.

Putting coal or coke into a stove is generally considered as inherently involving dust and dirt. Furthermore, the application of coal or colic or other solid fuel to a stove is usually haphazard as to quantity and the fuel is often spilled over the top of the stove.

My invention aims to provide a coal hod for filling a stove which eliminates dust and dirt in the application of the fuel to the stove. Furthermore, my improved coal hod acts in conjunction with the magazine of a stove to constitute a meter for determining the quantity of coal in the magazine at the end of a filling operation.

The nature of the invention and the mode in which I contemplate carrying out the invention will be apparent from the following description, which is to be considered in conjunction with the accompanying drawing forming a part of this specification, and of which:

Fig. l is a vertical sectional view of a preferred form of coal hod showing the parts in position during the filling of a magazine of a stove;

Fig. 2 is a similar view with the parts of the coal hod in different relative positions; and

Fig. 3 is a horizontal sectional view taken on the line 3--3 of Fig. l.

The coal hod or bucket may be made of sheet iron or other suitable metal and, in the form shown, comprises an outer cylindrical wall or casing l. The cylindrical member 1 may, as shown, be beaded at the bottom and top. The bottom end of the cylinder 1 is in a plane perpendicular to the axis of the cylinder and constitutes a support for the coal hod on the floor or on the stove. Within member 1 is an inclined bottom member 2 which is conical, forming a funnel or hopper. At the bottom part of member 2 is a horizontal opening 5 which is slightly above the plane of the lower end of the member 1.

Centrally disposed in the casing is a tubular guide sleeve 3. Sleeve 3 extends from the upper part of the coal hod downwardly and terminates short of the bottom member. The sleeve 3 may be flared outwardly at the bottom as shown at 8a. The opening 5 is of substantially the same diameter or size as the member 3 and the member 3 and opening 5 are in vertical alignment.

Radially extending stays i are connected at the top to the sleeve 3 and the outer member 1 for supporting the sleeve in the casing.

Mounted within sleeve 3 and freely movable longitudinally and rotationally therein is a tubular shaft 6 having near its upper end a bulge or stop 9 formed therein which is adapted to seat over the upper end of sleeve 3 and to determine the lowermost position of said shaft. A handle 10 is attached to the upper end of shaft 6 for carrying the coal hod and for moving the shaft 6 within the sleeve 3. A tubular valve member 12 is connected to the lower part of shaft 6 as by strips or supporting members 7a which may be integral with the parts 6 and 12. The parts 6 and 12 may be made from a single cylindrical tubular member by cutting openings 7 leaving the strips 7a. It will be seen that the strips 1a are diametrically oppositely disposed, though any connection affording rigidity is sufficient.

Upward movement of shaft 6 is limited by a flange 8 on the lower end of member 12, which flange extends radially outwardly and, in lifted position of the handle 10, contacts the lower end of opening 5. This closes the opening 5 and prevents discharge of coal or coke from the coal hod inasmuch as the member 12 is of such height that, in its upper position, the upper part of member 12 is adjacent or within member 3. The flange 8 in elevated position is substantially on alinewith the lower end of member 1 so that if the coal hod rests on the door, the lower end of member 8 is at the floor level and thus the floor holds the member 8 in such position that the opening 5 is closed and coal cannot leave the coal hod.

In the operation of the device, the coal hod is first filled. The coal hod may be on thefioor when filled so that the parts are in the position shown in Fig. 2 and the lower opening is closed. The coal hod being lifted by the handle 10, the lower opening remains closed. The coal hod is placed on top of the stove with the member 12 over the opening 11 in the stove member 13. Handle 10 is then pushed downwardly or allowed to move downwardly and may be rotated about its central axis to and fro in order to loosen fuel pieces which possibly have jammed against one another and against the walls of the valve or member 12 and which would prevent the move ment of the valve up and down or render such movement difiioult. When the parts have been moved into the position shown in Fig. 1, the fuel contained in the coal hod will flow into the upper part of member 12 and through member 12 and into the magazine space, filling the same, as

shown in Fig. 1, and leaving a side space 14 free from fuel. Upon drawing the slide valve 12 upwardly by means of the member 6 and the handle 10, the fuel remaining within and directly above the valve member 12 will flow down and occupy the unfilled space 14. The volume of the interior of the valve 12 is preferably such that the coal supplied when the valve member is drawn up- Wardly substantially fills the space 14 but so that the magazine does not overflow. It will be seen that with this arrangement the operation of the coal hod determines the amount of coal filled into the stove and prevents overflow.

It will be obvious that the discharge spout may be of any predetermined height with relation to any particular stove construction and may therefore control the maximum quantity of fuel to be filled into the stove. Inasmuch as the magazine remains entirely closed while the fuel is being applied thereto, the escape of dust or of combustion gases is eliminated.

While the invention has been set forth as applied to a coal hod, the invention in some or all aspects thereof may be applied to other uses. While certain novel features of the invention have been disclosed and pointed out in the annexed claims, it will be apparent that various omissions, substitutions and changes may be made by those skilled in the art without departing from the spirit of the invention.

What I claim is:

1. A coal hod comprising side and bottom members, said bottom member having a circular opening therethrough, and a cylindrical valve member substantially fitting said opening and movable vertically therein, said valve member closing said opening in elevated position and providing a depending discharge spout in lowered position.
