To all whom it may concern:

Be it known that 1, EDGAR E. Bnosms, a citizen of the United States, residing at Pittsburgh, in thccounty of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in l urnaceCharging Devices, of which the following is a full, clear, and exact description, reference being had to the accompanyingdrawings, forming part of this specification, in which Figurel is a side elevation partially in section of one form of my charging device, in which the furnace is shown in section.

Fig. 2 is a plan view of the charging bar and the supporting bearings.

Fig. 3 is a sectional view on the line III-ill of Fig. 1.

Fig. 4- is a detail view of a portion of Fig. 3 on a larger scale.

Fig. 5 is a side elevation of a elevis for supporting one of the charging bar bearings, and

Fig. 6 is a front VlG'W thereof.

This invention relates to an improvement in furnace charging devices and is designed to provide a cheap and eilicicnt device, Which is adapted to be used in connection with old and Well known overhead cranes.

The object of my invention is to provide a. device of this character in Which most of T the parts are of standard construction, so that they can be used in the construction of charging devices of various sizes. and also to meet the diiferent conditions of different furnaces, due to the available space for the charging device.

Another object of my invention is to provide a device having two suspended bcarings for the charging bar, one of which. is fixed at a prcdclcrinined level from the crane support and which is arranged to move about a horizontal axis to permit the charging bar to be oscillated vertically. The second bearing is arranged to be suspended by the hoisting cable of the crane, and so arranged that it can be moved about its vcrtical axis. to permit the bar to oscillate in a horizontal. direction. A. still further object of my invention is to form the charging bar of a plurality of tubular members, so that bars of various size can readily be constructed from sections of tubing cut to the res quired length for the particular bar to be constructed.

The precise nature of my invention will be best understood by reference to the accompanying drawings, which will now be described, it being premised, however, that various changes may be made in the details of construction and arranglmient of the parts, without departing from the spirit and scope of my invention, as defined in the ap 'iended claims.

Referring to the :wcolnpanying drawings, the reference character 2 designates a crane bridge which is supported on. a track 3 by means of trucks, such as shown at 4, in

such a manner that the crane is arranged to be moved in a l mgitudinal direction in front of a furnace, or furnaces 5. Supported on tracks 6 on the crane bridge by means of wheels 7 is a trolley 8. This trolley is provided with the usual lllOlOl' and a 'wind ing drum 9 for a hoisting cable 10. 11 is a swivel l-ioisting hook supportml on a cable 10 by in ans of a sheave 12. Connected to one end of the fran'lc work of the trolley Sis an extension 13 having a horizontally disposed I-beam 14., supported on the lower flanges of which is a second trolley 15. Connected to this second trolley 15 is a flexible suspending member ll), which I have shown as a chain. The lower end of this chain is provided with a clevis having an I -bolt 17 and to which is connected a yoke 18. 1!) is a. lock nut for securing the yoke 18 in its adjust d position to the bolt 17. livolally conncctci l to the yoke 18 by means of a pin 20 is a b airing 21 for supporting one end of the charging bar, the other end thereof being supported by a bearing 22 which is connected to the book 11 by means of a flexible member 23. The charging bar is built up of a central tubular section 2| which is lclcsciuncally connected at one end with a. charging head member 25. This charging head. member is provided with a groove in which are seated rollers 2c in the bearing 22. The other end of the tubular section 2% is connected to a flange of a journal member 27 havingan annular groove for the reception of roller bearings 28 within the bearing n'lcmbor 2'1. Seated within the member 27 is a tubular section 29, which is rigidly connected thereto and extends to a point beyond the journal 111111111301. 27 and which is provided with a hand-wheel 30 for rotating the charging bar. as hereinafter described. Roi-med integrally, or connected to the outer end of the charginghead mc1nbcr 25, is a head 81, which st ruck on an are from the center of the pin 20, and which is arranged to engage the usual head engaging recess, such as 32, of a charging box Slidably mounted Within the charging bar 24' is a charging box locking bolt 35, one end of which is arranged to be seated in an opening 36 in the charging box to retain it in position on the head 31 when charging.

' The other end of this locking bolt 35 is provided with an actuating head 37 which is mounted for reciprocation within the tubular section 29. 38 is an actuating lever for the locking bolt which is pivoted to a yoke or bearing 39 connected to the tubular section 29, and which extends through a slot in the head 37, so that the locking bolt will be moved by said lever. Connected to the bearing 21 in any desired manner is a countel-weight 41 which is arranged to counterbalance the weight of the box and the load therein. The trolley 15 can readily be moved along the flanges on the I-beam. 1a to move the charging bar in a horizontal direction, as indicated in dotted lines in Fig. 2.

42 is a charging box car which is arranged to be moved in a longitudinal direction in front of the furnaces on rails 43.

W hen it is desired to charge a furnace, the charging boxes are brought into their proper position in front of the furnace to be charged on the cars 42, and the charging apparatus is then brought into proper positier. with relation to the boxes. The operator then lowers the front end of the charging-bar to engage it with the recess in the box 33, and after the head is in its proper position, the bolt 35 is moved forwardly to lock the box in position on the head. As the end of the head 31 is of are form and is struck from the normally fixed center of the pin 20, the head 31 will readily enter the recess 32, as the position of this center is fixed at a predetermined height with relation to the crane and the boxes on the car -42. After the box has been secured in position on the head, the drum 9 is rotatcd to lift the bar and the box to the proper height with relation to the furnacedoor, the bar moving about the center on the pin 20. The trolley 8 is then moved ina longitlulinal direction withrelation to the supporting bridge to move the box on the end of the charging bar into the furnace. The operator then swings the charging bar about the axis of the hook 11 in a horizontal direction to move the box -to a predetermined position in the furnace, and during such movement the auxiliary trolley 15 will readily move along the I-beam 14, as the weight of the charging box is counterbalanced by the counterweight 41. After the box has been moved to the predetermined position within the furnace, it may be lowered, if desired, by means of the hoisting cable 10, and is then rotated by the hand Wheel 30 in order to dump the contents of the box into the furnace. After the box has been dumped, it is returned to the car 42 and the succeeding boxes are dumped in the same manner.

It will readily be understood by those familiar with the art that if desired the two bearing members may be supported in the reverse manner by means of the suspension members.

The advantages of my invention result from the provision of a charging device which can be used in connection with an ordinary crane, and in which one of the bearings is supported at a fixed height and is arranged. to be bodily moved horizontally and adapted to oscillate about a horizontal axis; together with a second bearing suspended by the hoisting cable and which is ar 'anged to oscillate about a horizontal axis and to be raised and lowered by the supporting cable. Also from the provision of a track supported on the crane trolley which is arranged to support an auxiliary trolley for the suspension cable for one of the bearings. Also from the provision of a charging bar which is built up of a plurality of tubular sections, so that charging bars of different lengths can readily be made from tubing cut to the proper length for the different sections.

I claim:

1. A charging bar having two supporting bearings, a tubular section rotatably mounted in one of said bearings and extending forwardly thereof, a charging head on the outer end. of said sectibn, a journal member rotatably mounted in the other bearing, a tubular section connected to said rotatable member and the end of the charging head in the other bearing, a third tubular section. connected to the journal memher and extending rearwardly thereof, a locking bar'extending from the last mentioned tubular section through the other tubular section and charging head, and means on the last mentioned tubular section for actuating the locking ha substantially as described.
