Specification of Letters Iatent. Patented Aug. 1919.

Application filed. May 215, 1918. Serial No. 236,646.

To all whom it may concern:

Be it known that I, EDGAR E. BROSIUS, a citizen of the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Machinesfor Charging Slabs, Billets, &c of which the following is a full, clear, and exact description, reference being had to the faccompanying drawings, forming part of this specification, in which- Figure 1 is a sectional elevation of a machine embodying my invention.

Fig. l is a diagrammatic view illustrating one way in which the peel may be suspended.

Fig. 2 is a similar view of a part of the machine on. a larger scale and with the movable parts in difierent positions.

Fig. 3 is a section on the line II IIII of Fig. 1, and

Fig. 4- is a section on the line IVIV of Fig. 2.

My invention is designed to provide a simple and efficient machine for charging slabs, billets and the like into furnaces; and more particularly, to provide a machine of this character which is hand manipulated and which can be operated by any usual crane mechanism. Also to provide a machine of this character by which the slabs and the billets can be readily and easily manipulated and brought into proper position.

The nature of my invention will be best understood by reference to the accompanying drawings in which I have shown a pre ferred embodiment thereof, and which will now be described,'it being premised, however, that various changes can be made in the details of construction and arrangement of the parts without departing from the spirit and scope of my invention, as defined in the appended claims. I

' In these draw-ings'the numeral 2 desig nates the peel of the charging machine or device, and which is shown as consisting of a tubular member journaled in a front bearing block 3 provided with roller or other suitable anti-friction bearings' l. The rear end portion of this peel member is connected by a tubular member 5 with the hub portion 6 of a rear bearing member 7, the

.latter being journaled on the anti-friction bearings 8 in the supension block 9. The block 9 is designed to be suspended from an overhead crane trolley (not shown) or-from a trailer attached to said vtrolley, as indicated by thesuspension chain 10. The front bearing block 3 is suspended, asindic'ated at 11, from the hook of any trolley of an overhead traveling crane (not shown), this suspension point being a movable point which allows of anydesired angle of operation.

12 designates a gear casing having the hinged cover portionv 12 and which is carried by a hub memlber 1-3 mounted in the forward end of the peel 2 on the anti-friction bearings 14. 1'5 designates a screw which extends upwardly into the gear casing 12 in Which it engages a sleeve-nut 16 17. Said screw extends downwardly through a guide block 18 and has an eye 19 at its lower end which carries a pin 20. 21 and 22 designate two links, .or toggles which, at one end portion, engage the pin 20, and which at their opposite end portions engage respectively the pins 23 and 24: which are seatedin oblique slots 25 in the guide block 18. 26 designate tong socket members which are respectively carried by the pins 23 and 24?, these socket members extending in opposite directions through openings in the guide block 18 and crossing each other withinsaid block. Secured to each socket memher is a tong member 27, the respective jaws 28 of said members being properly posi tioned to engage theoppo-slte ends of a slab or Ilzillet, such as indicated indottedlines at 29 is a beveled gear wheel whose, teeth engage theteeth'of the beveled gear wheel 17 before referred to, and which is rigidly secured to the endof a torsion rod 30, which extends backwardly throughv thepeel and .has an extension 31 at itsrear end which the Weight-on the tongs and tong centera.

having secured thereto a beveled gear wheel 38 is a ratchet on a bracket 42 secured to the bearing member 7.

to give the pawl a toggle-action which increases its. locking power on the ratchet wheel: 43 is a similar ratchet wheel secured to the peelextension 5 andhaving its teeth en:- gaged by a pawl 4i4-mounted on the bracket 45, also carried by the rear-suspension block 9; This last named pawl and ratchet device is a precaution against the possibility of the whole peel turning. on its roller bearing in a manner to tend: to: release thetongs.

The operation is as follows: The partsbeing iii-the position shown in Fig. 2, when the hand wheel 32 is turned in a clockwise direction, the screw 15 will be actuated to in turn actuate the l ink 21 and tongs 27 to close the latter 0n the slab or ingot the manner shown in Fig. 1. (hen the tongs are thus closed an extra pull on thehand wheel will setth'e pawl" 39 on the ratchet38, so as to maintain a constant pressure onthe tongs'suflicient to prevent their tripping, this being due to the spring in tlie rod- 30. The charging device with the ingotisthen lifted and moved by the'overhead crane to any desired point. If it is desiredtoturn the ingot in a horizontal plane about the vertical: axis ofthe screw 15, this can beeffected by turning the hand wheel 32 in clockwise direction; Inasmuch as the tongs-are closed upon the ingot, further relative movement of the nut and screw is prevented, and the entire peel will rotate on its frontand rear bearings.- The weight of the ingot on the screw, however, maintains thelatter in its vertical position, the hub portion 13 of the gear casing turning on the anti-friction bearings. 14. The gearing in the gear casing i the'reby caused to actin the manner of a differential gear to cause a rotation of the screw and nut, and thereby turn the ingot to the desired angle. as a safeguard to prevent any tendency of the entire peel to turn in an anti-clockwise direction onits bearings and thus tend to release the grip of the tongs. r

The advantages of my invention result from the provision of a simple and comparatively inexpensive charging device which can be lurid-manipulatedand operated by ordinary crane mechanlsm, and which is comparatively inexpensive.
