' Applicstionfiled August 12,1 eg7. malnirttnooi (lIenmdeL) i To all whom it may concern.-

Be it known that I, JOSEPH P. EOK, a citizen of the United. States, residing at Muncie, in

the county of Delaware and State of Indiana,

have invented a certain new and useful Irn-' provement in Electrical Apparatus for Oharg known as open-hearth? furnaces, with scrap or other iron and has for its object to provide a simple-and effective device for bringing about the several'opera'tion's necessary to perform the desired function .Tby a series of electrical motors, which are put under easy control of the 0perator;lwho stands upon a platform carried by': thetraveling crane or charging-frame. I1

With these ends in viewthis invention consists in the details of construction and comwhich this invention'appertains may undera' bination of elements hereinafter set forth and then specifically; designated-bythe claims. 1: In order that those skilled in the art to stand how to make and use'the same, the construction andoperat-ion will now be described in detail, referring to the accompanying drawings, forminga part of .this specifi-- cation, in which- Figure 1 is an elevation of an apparatus made in accordance with myimprovement, the

stationary supporting-tracks being in section Fig. 2; Fig. 4:, a section of a pOrtiOnof th'e' traveling crane, taken longitudinally through the charger-bar, showing the interior thereof; and-galcamqodafor locking the charging-pan to theouterlend of:zthis. bar; Fig. 5, a plan view .of the charger-tracks anditruck-frame adapted to run'thereon, and also the mechanism;for causing the charger-truck tracks to by means of th1s gearing.

move upon the supporting-tracks, so as to brin'glthe charger in its proper position relative' to the various doors of the furnace; Fig. 6, an enlarged section at the line 2, showing the oscillating casting and roller bearing through "which'the charger-bar passes; Fig; 7, an enlarged section of the outer end of the charger- I bar, illustrating the locking-cam holding the pan in position; and Fig. 8, across-section of theouter end of. the charger-barvupon a line I; with this cam,'the cam being turned upward inits locking position. Y

. In carrying out my invention as here embodied, K:is a track runningupon a runway L for carrying an electric crane. Each end of. track'K is carried upon a truck P. The lmachine'r'y for driving these trucks consists of a motor M and spur-wheels located at 9 or the backend of track K. The trucks are connected: by a shaft K, running the full length ofpthe track. This track may be carried from one end of the runway to the other Upon the track K'is located a charger-truck frame A and A D is the motor for driving the charger-truck carrying the loadinto the furna'ceand withdrawingithe charging-bar. 1 I The'spur-wheelsl). and D are connected to the shaft of the charger} truck. Spurwheel D? is made fast to the front'axle of the charger-truck and turns the flange-wheels D B is a hollow shaft used as'a charging-bar. Within this shaft is a small shaft orrod 0, on oneend of." whichis made fast a hand-wheel O. At theiother end is aneccentric cam G, which by turning thehand-wheel O is turned 7 within the, shaftorfextended through a notch in the wall of the shaft at the top, as shown in Fig; 7. 1

G represents the charging-pan, upon the back end of which is a large 'castin g, as shown. In this casting is a square .hole with a notch at the'back end, which cam O is made toenter by. means ;of the hand -,.wheel- 0 after the charging-bar. is entered into the square hole. This looks the charging-pan ,upon'the charging-bar securely, so that it maynot be off and left in the furnace. I

The charging-bar is supported-at' lfi by a casting H, which-is 'pivoted in casting-I, and casting I is bolted securely to A The chargdrawn IOO ing-bar is made to turn on pin-bearings X, X being a bearing similar to X and located at '7. On the back end of the charging-bar I is keyed a worm -wheel J for turning the charging-bar. Meshing into J is a screw T, and T is turned with a shaft by motor F, which is located upon a bracket bolted to the carrier U. Carrier U has a wide pin-bearing and shelf for motor 1 and motor F lowers and raises with carrier U, and the connecting wire is so coiled from the controller to motor as to hang loose. Carrier U is made to move up and down in slide U by means of the shafts It, the upper ends of which are threaded.

Motor E operates a shaft upon which is keyed two screws Y. These screws mesh into worm wheels V, which are screwed upon shafts R and held in place by brackets, as shown in Fig. 2. This gearing raises and lowers the back end of. the charging-bar I tilting the pan up or down.

N represents electric controllers.

l and 2 are field-wires stretched along one girder of the runway. A bracket-trolley supported from the truck I furnishes contact with these fieldwires. 3 and I represent a second pair of field-wires strung along the charger-track. 5 and 6 represent another pair of field-wires also upon the charger-track. These are connected to the switchboard at A and furnish current for motors D, E, F, and H, and this switchboard is for the purpose of making or breaking all of the currents from the controllers to the motors, so as to throw the current off when the apparatus is out of use.

Z represents a platform to accommodate the operator, and upon this platform are located the controllers N, here shown as four in numher, one for each motor, in order that the entire operations of the device may be under the immediate control of the operator standing upon the platform.

It is obvious that this immediate charger may be utilized in conjunction with a number of furnaces, the only requirement being that all of said furnaces are in a line in order that the charger-track may be brought into proper alinement with the doors thereof.

Having thus fully described my invention, what I claim as new and useful is 1. A furnace-charging apparatus consisting of a charger-track adapted to travel across the face of the furnace, a charger-frame adapted to run upon said track, a charger-bar pivotallysuspended within said frame, a rod rotatable in the charging-bar, a cam adapted to enter the wall of the charging-bar and engage the shank of the pan, means for raising and lowering the outer end of said chargenbar, and suitable electric motors in proper circuit for operating the various parts of the apparatus, as specified.
