STOKING-TOOL.

Specification of Letters Patent.

Patented Feb. *7, 1911.

Application filed September 23, 1910. Serial No. 583,531.

To all whom it may concern:

Be it known that I, IViLLuM-C. FAHY, a citizen of the United States, and a resident of the city of Philadelphia, county of Philadelphia, State of Pennsylvania, have invented an Improvement in Stoking-Tools, of which the following is a specification.

My invention has reference to stoking tools and consists of certain improvements which are fully set forth in the following specification and shown in the accompanying drawings which form a part thereof.

The object of my invention is to provide a stoking tool in the form of a hoe which shall have capacity for pushing or drawing the coals of the fire and so shaped at the corners that it may be employed for breaking up large clinkers.

My object is also to so combine the hoe or blade portion with the handle portion, that the former may be easily replaced when worn by use and said replacement may be made by the fireman. obviating the necessity of sending the tool to a machine or forge shop.

The invention consists of certain features of construction which are clearly illustrated in the drawings, fully described in the specification and more specifically defined in the claims.

Referring to the drawings: Figure 1 is a side elevation of a stoking tool embodying my invention with the middle portion of the handle broken away; Fig. 2 is a front elevation of my improved stoking tool with the handle removed; Fig. 8 is avertical section of the same on line a200 of Fig. 2; and Fig. i is a perspective view of one corner of the tool taken below the line yy of Fig. 2.

2 is the body of the hoe portion and has its top and bottom edges thickened as indicated at 3, said thickened portions being formed by flaring walls from the body 2 outwardly to the top and bottom edges. The sides or ends of the body 2 are reinforced by flanges 4, which flanges form a width across the end of substantially the width across the top and bottom, as will be readily understood by reference to Figs. 3 and 4. By this construction, the hoe portion of the tool has slightly recessed front and back faces which enable the tool to take hold of the coal when moved either forward or backward. It will also be seen that the union between the flange ends 4t and the flaring or thickened portions 3 of the top and bottom provide heavy corners with knife edges 5, and moreover pointed pyramid corners as will be clearly understood by reference to Fig. ft. These heavy sharp corners are most excellent in breaking up large clinkers. By the mass of metal which is provided at the corners, there is considerable resistance to wear notwithstanding the roughest uses to which the tool may be put.

Extending laterally from one face of the body 2 and arranged near the upper edge thereof, is a socketportion 6 which is preferably inclined slightly to the plane of the body so that when held horizontally by the handle, the hoe portion will take a slight incline, as indicated in Fig.1. This socket portion may be reinforced in its connection with the body by ribs 7 which extend downward and also laterally. as clearly indicated in the several figures. These ribs also stiffen the body and this is important inasmuch as it is subjected to great heat.

The handle 8 consists of a long iron tube which fits into the socket and through the body and has its other or free end secured to acast iron handle 9 by means of a rivet 10. The tube 8 forming the handle may be strengthened or reinforced adjacent to the stoking end by means of an iron rod 11 extending through the tubular handle Sfrom the hoe part 2 of the tool to a considerable distance beyond the end of the socket (S. In this way, the handle adjacent to the socket and stoking tool end is strengthened against being bent when overheated. The handle with its reinforced center is firmly secured in the socket by means of a bolt or rivet 12 extending through the walls of the socket and the handle structure.

The stoking end of the tool is preferably made of cast steel because of its great resist ance to heat, but for cheapness, it may be made of ordinary white cast iron or malleable iron, if so desired. In the use of this tool, the coal or clinkers may be drawn or pushed and will tend to move with the tool because of its shape, and the weight of the tool is such that it may be used as a hammer or cutting tool for breaking up or dividing clinkers.

The construction of the tool is such that a stoking end may be removed and replaced with respect to the handle by any ordinary fireman or mechanic and without the necessity of sending the tool to a machine shop with its consequent delays and expense.

lVhile I have shown my improved stoking tool in the form which I have found most suitable for commercial use, I do not restrict myself to the details, as these maybe modihed without departing from the spirit of the invention.

Having now described my invention what I claim as new and desire to secure by Letters Patent is 1. A stoking tool consisting of a hoe portion formed of a fiat plate having its upper and lower edges thickened considerably relative to the thickness of the plate portion combined with a handle secured to the plate close to but out of contact .with one edge and at great distance from the other edge.

2. A stoking tool consisting of a hoe portion formed of a fiat plate having its upper and lower edges thickened considerably relative to the thickness of the plate portion combined with a detachable handle secured to the plate close to but out of contact with one edge and at great distance from the other edge, and means for detachably securing the handle to the hoe portion.

3. A stoking tool consisting of a hoe portion formed of a rectangular fiat plate having its upper and lower edges thickened considerably relative to the thickness of the plate port-ion and also having the side edges flanged and said flanges blending into the thickened top and bottom portions to form sharp angular knife edged corners combined with a handle secured to the plate close to but out of contact with one edge and at great distance from the other edge.

4. A stoking tool consisting of a hoe portion formed of a fiat plate having its upper and lower edges thickened considerably relative to the thickness of the plate portion, and also having a handle socket extending from one face but greatly nearer one edge than the other, combined with a detachable metal handle fitted to the socket, and means for detachably securing the handle to the socket.

5. In a stoking tool, a hoe part made of a tending part way through the handle beyond the socket, and means for securing the handle to the socket.

6. In a stoking tool, a hoe part made of a flat plate having a handle socket extending from one face, combined with a tubular 1netallic handle forming a sliding lit in the socket, a reinforcing metal core fitting within the tubular handle and socket and extending part way through the handle beyond the socket, and means for securing the handle to the socket consisting of a transverse pin extending through the socket wall tubular ,handle and reinforcing core.

7. In a stoking tool, a blade portion consisting of a rectangular flat plate having its top and bottom edges thickened by inclined outwardly extending walls and having a handle socket extending laterally from one face nearer to the top edge than to the bottom.

- 8. In a stoking tool, a blade portion consisting of a rectangular flat plate having its top and bottom edges thickened by inclined outwardlv extending walls and having a handle socket extending laterally from one face nearer to the top edge than to the bottom, and said plate also having its vertical edges fiangecl and said flanges blending at the corners with the thickened edges to form sharp angular knife edged cut-ting corners.

9. In a stoking tool, a fiat rectangular plate having flanged edges uniting to form sharp angular knife edged cutting corners and a handle extending from the plate at a distance from the corners and edges thereof, and said plate being of less thickness in its middle portion than adjacent to the edges thereof.

10. In a stoking tool, a part for operating upon the fire having a laterally extending handle socket, combined with a long tubular handle fitted into the socket, a reinforcing core rod fitting within the tubular handle where it connects with the socket and for a distance beyond in the direction of the handle, and means for securing the handle and core to the socket part.

In testimony of which invention, I hereunto set my hand.
