4 Claims.

kThis invention relates to metal ingots and more lparticularly to ingots of thel type that are fed gradually into a melting ypot by an automatic feeder.

v j Prior to my invention ingots of such configuration and characteristics as to be adapted for use with automatic feeders of the Margach type for example have been devised. The"Marga ch feeder among other elements of equipment in-Y "c'ludes an endless chain `towhich may be attached at intervals a series'of hooks adapted to receive a series of ingotsA to be fed to the melting pot. One ingot for use with' the Margach feeder comprises simply an elongated bar, perforated near .35 oney of its ends in a manner to permit its being t Q the feeding of the ingots by the feeder into the molten bath with little attention from the operator Vduring the feeding process, arerelatively diflicult to thread onto the feeder prior to the feeding operation. Applicant has devised a new `r ingot of such proportions and configuration as to facilitate the loading of the feeder prior to ther feeding operation.

It is an object of the invention to provide a slip-off ingot suitable for use with the Margach s type or other feeders which is relatively rugged and facilitates the loading of the feeder. It is a further object of the invention to rprovide a 'slip-olf ingot having each end so formed as to o permit either end to be engaged with a Margach type or other feeder by a relatively simple operation.

' Other .objectsand the nature and advantages. Vof the invention will be apparent from the following description taken in conjunction with the accompanying drawing, wherein:

y Fig. 1 is a View in perspective of an ingot i accordance with my invention; Y

Fig. Zis a cross sectional view taken along lines *yz-f2 of Fig. 1 and looking in the direction of Y 5o the arrows;

Fig. 3 is a fragmentary view in perspective, ap-

-` proximately full size of an ingot attached to a'.v

,feeder ring of Aanautomatic feeder;

' Fig. 4 is a side elevation illustrating the feedi 55 fof t'hejingot into the melting pot; and,

Fig. 5 is a view similar `to Fig. 4 but with the feeding operation substantially completed, the ingot having slipped off the ring of the feeder.

Referring to the drawing, an ingot I0 comprising an elongated body portion I having a section ,-5

I2, as illustrated in Fig. 2, is formed at each of its ends I3 and |4 with a hook like configuration I5 and I6 adapted to be associated with the feeder hook ring as illustrated in Figs, 3 and 4. The ends I3 and |4 o-f the ingot bar I0 between the i0 hook portions I5 and I6 and the body portion have reduced portions I8 and I9, each of which are adapted to be grasped by the operator during the loading operation, or during the storing, packing, or shipping of the ingots. It is apparent .15 from the illustration that the portions I8 and I9 being situated as they are, are handy places for the operator to hold the ingot with a minimum of slippage, for if the operator will pull outward- 1y, the hooks |5 and I6 will become engaged. :'20

In the preferred form, the side 2D of the ingot bar I0 which is remote from the side 2|, at the Aends of which the hooks |5 and I6 arev formed, is substantially unbroken in configuration throughout the entire length of the ingot. The side 2| 25 at each end is formed with recessed portions 22 and 23, respectively, which recessed portions extend to approximately one-half the distance from the side 2| to the side 20 to form the hook ends I5 and I6, respectively. 30

When associating the ingot l0 with the hook ring I'I of the feeder chain 24, the ingot may be vsimply swung laterally toward the ring with one of the hook ends I3 or I4 slightly higher than the ring, great accuracy being unnecessary, until 35 virtue of the factthat the center of gravity of the said unmelted remaining portion is ofl center, until the remaining portion of the ingot slips off completely from the hook ring into the melting pot to complete the feeding of the ingot to the bath. The feeding machine Will then feed a second of a series of ingots to the bath in a similar manner and the cycle will be repeated. Y

It will be seen from the above that I have provided a relatively rugged, simple, slip-off type of ingot which permits of ready loading of automatic feeders of the Margach type feeder, for

example. It will further be understood that I have provided a slip-01T ingot of such configuration and characteristics as to permit of ready handling for shipping and storing.

As slip-off ingots, depend, for their association with automatic feeders, upon the configuration of their ends, any injury to same will prevent Athis necessary association. Accordingly, breakage at the end during handling, shipping or otherwise, prevents this association and necessitates recasting of the ingot, makes for delay, and is otherwise objectionable. Hence, each end of the ingot has been so formed as to permit of association with the hook ring of the feeder chain whereby even though one end is injured so as to prevent it being hooked through the hook ring, the other end may be so associated with the feeder hook ring. The particular configuration, then, at each end of the ingot performs the dual function, of first, facilitating handling, and second, effects the saving of time when one end is injured. Y.

While it is conceivable that ingots in accordance with my invention might be cut to shape, I prefer to cast them in a mold with the hook portions pointing in a horizontal direction, sufficient draft having been provided as indicated in the section illustrated in Fig. 2.

Though the ingot bar Ill has been described as having end portions I3 and I 4 including hook like configurations I5 and I6 and reduced portions I8 and I9, it is to be understood that the portions of the ends I3 and It may also be denoted by the terms nose part and base part.

-For example, the projecting portion to which the reference numeral I6 has been applied may be called the nose part of the end Ill and the reduced portion I9 may be called the base part of the end I4 and further, the reference numeral III may generally denote the entire hooked end including the portion I9 and the portion I6.

It will be obvious to those skilled in the art that various changes may be made in this device Without departing from the spirit of the invention and therefore the invention is not limited to What is shown in the drawing and described in the specification butfonly as indicated in the appended claims.

I claim:

LA slip-off ingot of the type suitable for use with an automatic type metal feeder and adapted to be substantially vertically suspended, said ingot comprising an elongated body portion and a hook shaped end portion for engaging the feeder, the center of gravity of the mass of the hook shaped end portion being so laterally remote from the longitudinal axis of the body portion as to effect an unbalancing of the hook end with relation to the feeder when the body portion has melted from the ingot, whereby a feeder'ingot engaging element associated with the said feeder may readily be threaded by said ingot end with the assurance that upon melting of the ingot up to the ingot end, the said ingot end will automatically disengage itself from the'feeder.

2. An ingot as in claim 1, having symmetrical ends whereby the loading of said feeder may be facilitated.

3. A slip-off ingot of the type suitable for use with an automatic type metal feeder, said ingot comprising an elongated body portion and a hooked end portion, said hooked end portion including a base part and a nose part, said base part being heavier than said nose part, whereby when said ingot body portion has been melted, said base part will overbalance said nose'part and automatically disengage itself from the feeder.

4. An ingot as inV claim 3 having symmetrical ends whereby the loading of said feeder maybe facilitated.
