CHARGlNG-BUGGY.

SPECIFICATION forming part of Letters Patent No. 694,332, dated February 25, 1902.

Application filed November 20 1901. Serial No- 83,023- (No model.)

T (1 whom it may concern:

Be it known that I, OSCAR SUNDT, of Cleveland, Ouyahoga county, Ohio, have invented a new and useful Charging-Buggy, of which 5 the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in whieh- Figure 1 is a side elevation showing my improved tilting buggy in position about to discharge the ingot, the tilted position being indicated in dotted lines. Fig. 2 is a top plan view of the bugg and Fig. 3 is a vertical cross-section showing the supplemental shifting or moving device.

Myinvention relates to the buggies used for taking ingots to and depositing them upon a rolling-mill feed-table and is designed to simplify and improve the buggy and the mechanism for tilting it to discharge the ingot or bloom. To that end it consists in a buggy having a tilting holder pivoted thereon, the parts being so arranged that when the bugg strikes a stop the momentum of the ingot will automatically tip the holder and deposit the metal upon the table.

In the drawings, in which I show a preferred form of my invention, 2 represents a buggy having rear wheels 3, resting upon rails 4.

0 The buggy is preferably formed of strong steel castings and is provided in its rear portions with a chamber arranged to receive an electric motor 5, having slow-motion gearing 6 connecting it to the rear axle to drive the 5 buggy. The front part of the buggy is of yoke form and is provided with bearings 7 7, containing the trunnions 8 of the tilting holder 9. This holder is provided with side trunnions or stub-shafts, on which are pivo oted the front wheels 3. The rear portion of the holder is provided with the ingot-receiving cavity, which is open-topped, so that the ingot may be lowered into the holder, and projecting from its front portion are a pair of rockers 10, having curved front faces. These rockers are arranged to roll or rock upon a bed 11, situated between the tracks in the rear of the feed-table, whose rollers are indicated at 12, and at the sides of this bed portion are track extensions 13, having a sharp upward rise or curve, up which the front wheels of the buggy travel as its momentum is gradually absorbed during the tilting of the holder.

In the operation of the device when the ingot has been lowered into the holder the car is driven along the track by its electric motor, and as its'front wheels strike the upwardlycurved portions of the track the shock and the momentum of the metal and holder cause the holder to tilt as the wheels ride up the inclined or curved portions of the track. The holder is thus swung into position, (shown in dotted lines in Fig. 1,) depositing its contained ingot upon the feed-table rollers, the car then rolling back to the normal tracklevel. The amount of tilting of the holder is controlled by lugs 14 on the rockers, which contact with the frame in the position shown in dotted lines, and the center of gravity is then in such a position that the holder tilts back to place as the car runs back down the incline.

To insure against improper operation of the device by reason of its not traveling up the inclines a suffioient distance to eject the ingot, I provide a positive pusher arranged to act upon lugs 15, projecting from the side frames of the car or buggy and arranged to force the buggy forward and lift it. I have shown this apparatus as consisting of two blocks 16, pivoted to rear ends of connecting-links 17 and having rollers 18, which travel upon a bed or track having a downwardly-curved roar portion, as shown at 19. The links are connected to lever 20, secured to a rock-shaft 21,

extending laterally and actuated by motive cylinder 22, by means of which the shaft may be rocked in either direction. In case the motor has not given the car suflicient momentum to carry it to the desired point, fluid is admitted to the motive cylinders, and the links connecting the blocks are thus drawn forward. The blocks first rise or tilt from the position shown in full lines to that shown in dotted lines, and in such position they contact with the buggy-lugs and positively force it up the incline, the holder rocking on the bed-plate and discharging the ingot.

The advantages of my invention result from the simplicity of the buggy and its connections, all connections for tilting the holder being done away with. The weight of the holder and rockers is so proportioned with respect to the pivotal axis that when the ingot is in the holder the shock occasioned by the buggywheels striking the rise in the track will cause the tilting of the holder. The device for moving the buggy part is merely supplemental and is not ordinarily required. As the buggy carries its own motor, the system is self-contained, easily operated, and not liable to get out of order.

Many variations may be made in the form of the car, the holder, and the track Without departing from my invention.

I claim- 1. A charging-buggy having a holder pivotally mounted thereon, wheels pivoted to the holder, and mechanism for suddenly slowing up said wheels and thereby tilting the holder; substantially as described.

2. In rolling-mill feed mechanism, a feedtable, a track leading to its end, a wheeled charging-buggy having a tilting holder pivoted thereon, supporting-wheels pivoted to the holder, and mechanism for slowing up the holder-wheels at the end of the table to cause the tilting of the holder; substantially as described.

3. A track, a wheeled buggy movable thereon, a holder pivoted to the front portion of the buggy, wheels pivoted to the holder, and upwardly-curved inclines arranged to contact with the holder-wheels to cause tilting of said holder; substantially as described.

4. A Wheeled charging buggy having a holder pivoted in its front portion, a bed portion between the tracks and rockers on the holder arranged to rock upon said bed por tion; substantially as described.

5. A feed-table, a track leading thereto, and having upwardly-curved portions adjacent to the table, a wheeled buggy movable upon the track, and a holder pivoted in the front portion of the buggy, said holder having supporting-wheels pivoted thereto and also pro vided with curved rockers; substantially as described.

6. Afeed-table, a track leading thereto, a charging-buggy movable upon the track and having a drivingmotor thereon, a pivoted holder on the buggy, mechanism for tilting the holder as the buggy nears the table, and a push device arranged to engage the buggy and move it forward in the latter portion of its travel toward the table; substantially as described.

'7. A charging buggy having a pivoted holder, mechanism for tilting the holder as the buggy is moved forward at acertainpointin the track, and pusher mechanism arranged to engage the car near said point and force it forward; substantially as described.

8. A feed-table, a track leading thereto and having upwardly-curved end portions adjacent to the table, a buggy movable on the track and having a driving-motor, a pivoted holder mounted on the buggy and arranged to tilt as the buggy rides up the raised track portion, and a stationary motor having a pushing device arranged to engage the buggy and force it forward and up the incline; substantially as described.

In testimony whereof I have hereunto set my hand.

OSCAR SUNDT.
