UNTTED STATES PATENT UTTTQTL HARRY JOSEPH ROWE, OF NEW KENfi-INGTON, PENNSYLVANIA.

CHARGING APPARATU$.

T0 aZZ whom it may concern:

Be it known that T, HARRY J. Rows, a citizen of the United States, and a resident of New Kensington, in the county of l Vestmoreland and State of Pennsylvania, have invented a new and Improved Charging Apparatus, of which the following is a full, clear, and exact description.

My invention comprises a device for charging furnaces by supplying fuel and other materials thereto, and it comprises certain improvements whereby the load can be carried to the supply opening of the furnace and automatically delivered to the interior of the same as soon as the carrier on which the load is placed reaches the supply opening.

Reference is to be had to the accompanying drawings forming a part of this specification, in which the same characters of reference indicate the same parts in all the views.

Figure 1 is a vertical sectional view taken through the center of my charging apparatus and showing the furnace and the manner in which the charging apparatus is mounted with respect to the same. Fig. 2 is a hori- Zontal section on the line 22 of Fig. 1; Fig. 3 is a sectional view of the charging apparatus taken on a plane passing centrally therethrough at right-angles to the plane of section on Fig. 1; Fig. l is a section on the line e it of Fig. 1; Fig. 5 is a top plan and Fig. 6 is a detail view partly in section, showing the manner in which the gate controlling the supply opening is mounted.

My invention is used in connection with a furnace 1, which may have an arched top 2 and be provided with a supply opening 3 located at any convenient point. This opening is supplied by means of a carrier which moves along guide rails 4:. These guide rails are shown as vertical, and are three in number, secured together at their upper ends by means of a triangular framework 5 arranged at the top of the side wall of the furnace and held in place by means of tie rods 6 passing through both side walls of the furnace and through a cross-bar 7 at the opposite ends, this cross-bar being sup ported upon vertical rails 8 on the opposite side, so that the sides of the furnace will at Specification of Letters Patent.

all times be prevented from bulging out- Ward.

The supply opening 3 is controlled by means of a sliding gate which moves up and down in vertical slots 9 in the adjacent side rails 1-, and this gate comprises a retangular frame 10 of metal, which is filled in with firebrick 11. The upper side of this frame is secured to a bar 12, the ends of which project into the slots 9 above noted.

The carrier or elevator which supplies the furnace through the discharge opening 3 is shown at 13, and this elevator is preferably provided with rollers 14: at the back near the top thereof, mounted upon a transverse shaft 15. These rollers are flanged and engage the rails 4; and assist to guide the platform or elevator in its up and down movements. The front of the carriage also carries a third roller 16 arranged centrally thereof and in the same horizontal plane as the rollers let. This roller 16 is mounted upon a short shaft 17 carried in hearings in a casing 18 supported by the elevator, and it engages the third or front rail 4. A similar centrally-located roller is located below the roller 16, and in the plane of this lastnamed roller are supplemental rollers 19 carried by short shafts 20 which rotate in bearings 21 formed in the sides of the elevator 13. These rollers 19 engage the back rails 4t, and the carriage 13 is thus guided by three upper and three lower rollers, two in back and one in front in each case, pass ing along the rails 1- in its up and down movements.

The platform may be provided with an upper floor 22 and a lower floor 23, the upper floor having vertical ribs 2 t extending upward therefrom and fro-m the back to the front of the elevator, these ribs having apertures through which the shaft 15 passes. Similar ribs 25 may be carried by the lower floor 23, the short shafts 2O terminating outside of these ribs. These ribs and the floors which carry them strengthen the elevator or carriage, as will be readily understood The carrier is raised and lowered by means of a cylinder 26, to which the motive agent is supplied by means of a conduit 27.

In this cylinder moves a piston 28, the rod 29 of which passes through an aperture in the lower floor 23 of the carrier, and is rigidly secured to the upper floor 22. hen this piston rises it carries the carrier up with it, and when the motive agent is with drawn from the cylinder it lowers the carrier. The lower floor 23 has an enlarged opening 30 therein to give passage to rod 29.

The carrier 13 is provided with a tilting table 31, this table also having a rim around its edges, and it is mounted to oscillate upon a spindle 32 mounted in bearings 33 formed in the sides of the carrier 13. A suitable bearing in the form of a sleeve 3 1 is secured to the bottom of this table in line with the bearings 33, so as to mount this table upon the spindle in the proper manner.

The table is tilted by means of a chain 35 secured to a lug 36 on the bottom at the end adjacent the furnace wall. This chain is anchored to a staple 37 at its lower end, and passes through apertures 38 in the floors 22 and 23 of the carrier 13.

lVhen the furnace is to be charged the carrier is loaded by heaping fuel or other materials, such as metals to be melted upon the table 31 and compressed air or steam, or even water power may be then supplied to the cylinder 26, to raise the piston 28. At this time the table will be kept horizontal, owing to the weight of the load upon it, the spindle 32 not being centrally located with respect to this table, whereby one edge of the same will rest upon the upper casing 18 for the gear 16. Furthermore, the gate will be in such position that it will close the supply opening 3, the weight thereof causing it to hang in such a position that the ends of the bar 12 will be at the lower ends of the slots 9. Vihen the carrier 13 rises, however, it will engage the lower edge of the gate and push the same upward to uncover the supply opening 3. Then the supply opening has been uncovered the chain 35 will become taut, tilting the table and causing the load thereon to slide off the same through the opening 3 into the furnace.

I prefer to arrange the parts so that normally the cylinder 26 will be below the level of the bed of the furnace, and to this end I excavate a pit shown at 39 and line the same with brick or any suitable material shown at 10. The cylinder may be of any desired length, and the opening 30 in the lower floor thereof may be wide enough to allow the upper end of the cylinder to pass therethrough. Consequently, when it is desired to load the table the carrier may be allowed to'sink far enough to bring the table 31 approximately to the level of the ground.

My invention is preferably intended for use in supplying fuel to furnaces, but ohviously it is not restricted to this field alone.

I may use it under any conditions that requirethe transportation of materials and the automatic delivery of the same from the carrier when the end of the travel of the latter is reached; and while I have shown the carrier as mounted to move vertically on the drawings, I do not wish to be limited to this vertical movement, as under some conditions it may be necessary to move the fuel or whatever else is carried by the table 13 in a horizontal or slanting direction instead.

My invention is especially useful in connection with tin melting furnaces and other plants used, for the purpose of fusing metals. hen I use my invention toaccomplish such objects the metals which are to be worked are loaded upon the platform 31.

I desire to have it understood further that the above description is illustrative only and discloses but one embodiment of my invention; that I do not care to be limited to the exact details thereof, but wish to reserve to myself the right to make such changes inthe shape, size and arrangement of the parts as fairly come within the scope and spirit of my invention.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:
