Be it known that I,

' Munhall, in the county of Allegheny-and State section of the same.

ing-box, showing the socket.

My invention relates to the means for detachably connecting an operating member,

such as the charging-bar of a machine for charging open-hearth furnaces, with a part, such as the charging-box, which is to be operated. Heretofore'these charging-boxeswere.

necessarily placed in accurate alinement with each other by reason of the fact that the head of the charging-bar moved downwardly into a broad vertical slot in the end of the box,- the flanges of the head fitting neatlywithin this socket, so that the-box wouldnot tilt. As.

the motions of the charging-bar are necessarily limited in character,the operation of attaching the bar to the.boxes was a difficult and tedious one. My invention entirely overcomes thesedifficulties and enables a charging-bar tobe used'which can be moved end wise into an open-ended socket at the end of the charging-box without the necessity of accurate alinement of these boxes, while the head of the bar is quickly and easily secured to or disengaged from the box-socket.

In the drawings, in which similar numerals indicate corresponding parts, 2 represents the casting forming the end of a charging-box,

this casting having an open-ended socket of general rectangular form, with its side 3 inclined or beveled outwardly, as shown. The

head l of the charging-bar 5 is provided with inclined faces 6,; which are anr'anged to slide over the inclined faces 3 of the charging-box socket and fit neatly within such socket.

This head is provided with a horizontal slot 7,

fwithin which are pivoted levers 8, said levers ALVA O. DINkEY, of,

operated by a wedge Fig. 3 is a partial hori-' zontal section of a modified form'of mechan-, ism; and Fig. 4=.is an endvie-w of thecharg I Application filed February K0. 624,686- (No model.)

a rod 12, which passes longitudinally through the charging-bar and may be operated by an Ihaving'locking projections 9, arranged to enter'recesses 10 in the end faces of the socket. In the form of Figs. 1 and 2 the levers 8 are u 11, secured tothe end of electric motor, a hydraulic cylinder, or any other suitable means. A second wedge 13 may be provided, which acts upon the rearv ends of the levers 8 to positively move their outerendsinwardly, though this is not essential. Ijinay-useother means for operating these levers-such, for instance, as thetog'glelinks 14 0f 'Fig. 3-'-which pivotally connect the levers 8' with the end of the operating- The operation of the device is apparent.

The boxesare placed on a suitable support and do not need to be accurately alined since the end of the charging-bar as it enters the socket by sliding over the inclined faces will move this end of the box, so as. to allow the entrance of the charging-bar head. I The 1ever's 8 then being moved outwardly by the wedge 01 other device therefor, the head and thehox are locked together, so that the box may be carried into and out of the furnace and turned at any point.

The ad vantages of the Invention result from the fact that fewer movements'of the charging-bar are needed, since its head moves endwisedirectly into the open-ended socket, and

the head itself as it enters the socket will bring the box into proper position for lockmg; to the box are easily performed, and the whole device is of few parts and not liable to get out of order. 3 1 Many variations in the form,constructi0n, and relative arrangement of the parts of my device may be made by the skilled mechanic The locking and'unlocking of the head without departure from .my invention, since What I claim is- 1. The combination with an element having at one end an open-ended socket, of a movable bar having a head arranged to move endwise directly into the socket, and a look ing mechanism arranged to rigidly connect the .bar and socket.

2. The'combination with an element to be operated, having, at one end an open-ended socket with inclined inner faces, of a bar movable endwise directly into the socket and having a head provided with inclined faces arranged to slide over the inclined faces of the socket and fit therein, a locking mechanism arranged to rigidly lock the head to the socket, and means for unlocking the head in any position of the element.

3. The combination with an element, having at one end an open-ended socket, of a bar having a head movable endwise directly into the socket, lockinglevers in the head. arranged to engage recesses in the sides ofithe socket and rigidly lock the head therein and means for positively moving said levers to lock or unlock the head in any position of the element.

4. The combination with a charging-box, having at one end an open-ended socket provided with inclined inner faces, of a charging-bar having a head provided with inclined outer faces arranged to fit within the socket,

locking-levers pivoted within the head and myhand.
