STOKING DEVICE Filed Nov. 30, 1935 FIG N J1; 1" INVENTOR ATTORNEY Patented Nov. 17, 1936 UNITED i s Es PATENT OFFICE STOKING DEVICE Frederick L. Balzer, Beaver Falls, Pa. v Application November 30, 1935 Serial No. 52,377

2 Claims. (01. 294-11) are secured to the hollow rod l, and the blade 3, i V

This invention relates to new and useful improvements in devices for stoking fuel beds and the like and is particularly adapted for use in the stoking of small furnaces.

It is among the objects of the invention to provide a combination stoking tool which shall be especially adapted for the arrangement of the fuel beds of furnaces to obtain maximum combustion efficiency thereby eliminating the waste of combustible gases by passage through the stack.

A further object of the invention is the provision of a stoking device of the above designated character which shall be provided with means for removing large or small clinkers from the fuel bed and which means shall be operable in a convenient and accessible manner without exposing the user to the intense heat of the furnace.

Still another object of the invention is the provision of a stoking device of the above designated character which shall be of a construction and shape to render it useful for removing the ashes from the ash pit of a furnace.

These and other objects of the invention will become more apparent from a consideration of the accompanying drawing constituting a part hereof in which like reference characters designate like parts and in which:

Figure 1 is a plan view partially in section of a stoking device embodying the principles of this invention;

Figure 2 a sectional elevational view thereof;

Figure 3 an end elevational view; and

Figure 4 a cross section near the end taken along the line 4-4, Figure 2, with a portion of a gripping jaw broken away.

With reference to the figures of the drawing, the numeral l designates a hollow rod or tube having a grip or handle portion 2 at one end and a relatively wide and long blade 3 at the other end, the device in appearance resembling a hoe. As appears in Figures 1 and 3 of the drawing, the blade element 3 is provided with ribs or corrugations 4 which give it a structural shape, making it highly resistant to bending and other distorting stresses. The blade element is attached to the end of the hollow rod l by welding it direct on the face of the rod or it may be otherwise secured in a manner not to interfere with the free movement of a rod 5 that is disposed within the hollow member I.

The free end of the blade 3 is inclined or bent at 6, Figures 2 and 3, to constitute one face of a jaw-like member, which cooperates with a movable jaw I having a serrated surface 8, and which is pivoted at 9 to a pair of angle brackets 10 that as shown in Figure 2 of the drawing.

The assembly of the jaw and its relation to the angle brackets and hollow rod 1 is shown in the enlarged view of Figure 4 wherein it is shown that a portion of the jaw extends through a slot II of the tube into the bifurcated end of the rod 5 to which it is pivotally joined by a rivet I2.

With reference to Figure 2 of the drawing, the rod 5 within the tube I extends into the handle portion 2 and is itself provided with a handle or grip I3, which constitutes an abutment for a helical spring M, the other end of which abuts against the end face l5 of the hollow rod I.

As hereinbefore stated under the objects of the invention, the stoking device has several uses as follows:

The normal position of the jaw 1 is that shown in Figure 2 in which position it is held by coil spring M which extends rod 5 in the direction of the grip or handle 2, thus pulling on the short lever of jaw l and causing the jaw to abut against the in-turned end B of the blade 3. In this position, the blade 3 may be inserted in the ash pit to scrape and remove the ashes therefrom by placing it lengthwise on the floor of the pit.

By holding the stoking device in the position shown in Figure 2, it can be used to break-up clinkers and to sink into the fuel bed to loosen up the bed. Such manipulation of the stoking device will bring the clinkers to the top of the fuel bed, and by gripping the handle [3 of the rod 5, the latter can be pressed forward, causing jaw l to retract as shown by dotted lines in Figure 2 and by permitting the handle I 3 to be extended either by action of the coil spring M or by pulling it, or both, jaw 1 will engage either a very small or large clinker by coaction with the face and particularly the end 6 of the blade 3. By releasing the jaw 1 whereby it assumes the normal position of Figure 2, the blade 3 can be deeply sunk into the fuel bed at the portion adjacent the door of the firebox, and the hot ashes can then be pushed forward against the back wall of the firebox. In this manner, all of the hot coals or ashes can be displaced from the front portion of the firebox adjacent the charging door to make place for coal or coke, which is charged into the firebox.

This method of stoking fuel beds is most efficient as the products of combustion, including the volatile gases, must pass over the hot coals to pass to the stack, usually located at the rear of the firebox, and the combustible gases are thus consumed to generate heat instead of passing in an unburnt condition into the stack.

One of the features of the hereinbefore described stoking device is the normal bias of the jaw 1 against the blade 3, which leaves the operator free to grip only the handle 2 for manipulating the stoking device in the hereinbefore described manner. It is only necessary to manipulate handle l3, when the device is utilized for the removal of clinkers from the fuel bed.

Although one embodiment of the invention has been herein illustrated and described, it will be apparent to those skilled in the art that various modifications may be made in the details of construction without departing from the principles J herein set forth.

I claim:

1. A stoking device comprising a relativelywide and long blade having a hollow manipulatingrod secured thereto, said blade and rod being hoe-like in appearance, said blade being corrugated and" axis of the blade, and a rod within said manipulating rod pivotally connected to said movable jaw, said movable jaw being of substantially less width than the corrugated blade.

2. A stoking device comprising a relatively wide blade of substantial length having a hollow manipulating rod attached at the top end thereof, said rod having a looped grip at the opposite end thereof, a movable jaw pivotally mounted adjacent the blade, the jaw extending substantially parallel to the inner face of the blade, a rod disposed in the hollow rod portion and extending beyond the end thereof, said inner rod being pivoted to the movable jaw, and being provided with-a grip, and a spring disposed between the grip and hollow rod to normally bias the inner rod in a manner to extend the movable jaw into abutting engagement with the blade, said blade and jaw having their ends in-turned to constitute a gripping jaw, and said movable jaw being of substantially less Width than the blade and having its in-turned portion serrated.
