Specification of Letters Patent.

Patented Sept. 25, 1906.

Application filed January 6. 1906. Serial No. 294.979.

T0 aZZ whom it may concern:

Be it known that I, WVILLIAM T. MARTER- STECK, a citizen of the United States, residing at Sharon, Pennsylvania, have invented certain new and useful Improvements in Charging or Drawing Machines for Heating-Fur naces, of which the following is a specification.

My invention relates to a machine for charging and drawing heating-furnaces and is designed to materially simplify the construction and give greater effectiveness in manipulation; and to this end I have devised a construction which enables the operator to remain in one position in the manipulation of the boom, to have a clear vision of the boom end in charging and drawing the ingots,*and to provide such range of movement of the end of the boom as will permit the ingot to be lifted from the floor in case the dogs drop it.

So far as I am aware charging and drawing machines prior to my invention have been operated with more or less damage to the furnaces by reason of the fact that the framework and supporting structure leaves but a narrow Space for the working of the boom and the operator is unable to get a clear vision of the space beyond the line of the furnace-doors, with the result that when the boom is withdrawn it frequently occurs that the ingot will come in forcible contact with the sides of the door, thereby. injuring the structure, and I have overcome this entirely by my construction by dispensing with the obstructions, the o erator standing upon a platform in rear of tffe boom with his head above all the mechanism, so that the entire opening of the door is plainly visible and there is no danger of coming in contact with the adjacent walls of the door. The boom has a greater range of movement than has been found possible heretofore, with the result that the operator may pick up from the floor any ingots that may be dropped by the dogs either 1n charging or drawing, and this is a very great advantage.

Another advantage of my construction is that the boom is operated independently of the platform upon which it is supported and on which the operator stands, the result being that the operator maintains his position upon the stationary platform instead of moving with the platform, which in the constructions heretofore used have been raised and lowered with the movement of the boom.

In the form of the device shown the machine is adapted to run on the charging-floor, which renders unnecessary a heavy furnace-building with depending supports from an overhead structure, though I do not limit myself in this connection, as it is possible to utilize my improved construction with supporting means extending to an elevated framework.

I have illustrated the invention in a form preferred by me in the drawings, in which Figure 1 is a sectional elevation showing a part of the structure. Fig. 2 is an elevamechanism, and Fig. 3 is a plan View.

The machine is supported upon a bridge A, which may be of open framework of suitable dimensions and strength, and this runs upon suitable tracks back and forth in front of the series of furnaces under the manipulation of the operator, so as to bring the device in front of any furnace of the series, as is common. Mounted upon this bridge A is a carrier B, which moves back and forth upon the bridge at right angles to the movement of the bridge, so as to permit the charging and drawing of the furnace. upon suitable tracks, and it may be operated back and forth by a suitable motor (indicated at B) or in any other proper manner. The carrier B supports a turn-table C, which is rotated through suitablegear connections by means of a motor 0. The turn-table is supported on cone-rollers G which run on the rim of the internal gear B and bear upon the track-ring C. Supported on the turntable-O is the boom D, the bearing of the boom being shown at D. The boom is given an up and-down-motion through the motor D by means of the gearing D and the segment-gear D The boom is provided with dogs D at its front end, which approach toward and recede from each other by the backand-forth movement of the screw-rod D operated through a motor D and a suitable gearing, as more fully described in a companion application of even date herewith, Serial No. 294,978. The platform where the operator stands is immediately in rear of the segmental gear for operating the boom, and it will be observed that the operator in a standing position is above all the mechanism and has not only a clear view of the end of the boom, but of the furnaces being charged or drawn, and, indeed, there is nothing between him and the door-openings, so that he can readily and accurately direct the end of the boom in charging and drawing, so as to avoid any tion of the boom with part of the operating The carrier moves damage to the walls of the furnace-opening. This construction renders the raising and lowering of the boom with its mechanism unnecessary, as is common in the type ofdevices having the boom. supported from a depending structure, and the tilting action of the boom is entirely sufficient not only in the charging and drawing of the ingots from the furnaces, but also to pick up from the floor any ingots that may have been dropped.

' What I claim is- 1. In a device for charging and drawing ingots and the like, a bridge, a carrier mounted above the same, a turn-table mounted above and on. the carrier, a platform for the operator supported by the turn-table above the carrier, and a tilting boom. mounted. on the turn-table, substantially as described.

2. In a device for charging or drawing in gots, a bridge running upon the chargingfloor, a carrier, a turn-table mounted. thereon, a tilting boom carried by the turn-table and a platform for the operator having no vertical movement.

3. In a device for charging and drawing ingots and the like, a bridge, a carrier mounted above the same, a turn-table mounted on the carrier and having a platform located above the carrier and a boom pivotally supported by and above the platform, said platform being extended for the occupancy of the operator, the relation of the parts being such as to bring the head of the operator above the operating mechanism and to give him a clear vision of the furnaces and the working end of the boom, substantially as described.

4. In a device for charging or drawing ingots and the like, a bridge suitably supported, a carrier mounted thereon, a turn-table on the carrier, said parts having horizontal movement only, a boom pivoted on the turntable and a platform. for the operator carried by the turn-table, the boom and its operating mechanism all being below the level of the operators head so as to provide an unob structed View of the furnace and the end of the boom, substantially as described.

5. In a device for charging or drawing ingots and the like, a bridge running upon the charging-floor, a carrier or trolley having movement on the bridge, a turn-table mounted upon the carrier and a boom pivoted to have tilting movement surmounting the platform of the turn-table, substantially as described.

In testimony whereof I afliX my signature in presence of two witnesses.
