Application June 20, 1945, Serial No.2600-,595 6 Claims. (Cl. 2_14-26) 1 , 2 VThe box 6 of Fig. 1 is shown in more detail in Figs-2 to 6 inclusive. This box is open-topped and has a bottom Ill, a low end II, a high end I2, a low side I3, and a high side I4. The high end I2 is provided with a wall I5 spaced apart therefrom and slottedas at I-B to receive the free end of peel This invention relates generally to the art of handling solids, and particularly to new appara tus for use with an open hearth charging ma- chine in cleaning solids from the charging floor in front of an open hearth furnace. During the operation of an open hearth fur» nace various solids are charged into the furnace and some ofk those solids are spilled onto the charging floor in frontl of the furnace. Hereto fore such solids have been cleared away by hand 5 and'isalso providedwith holes I'I to receive pins at the end of the peel. ' When the free end oi the peel 5 is inserted between the-end wall I2 and spaced wall I5 and the pins are inserted in holes I‘I, the- box may be lifted, rotated and moved end wise by the peel and' also moved sidewise when the charging machine runs along its rails. shoveling which necessitated the expenditure of considerable labor. The present invention pro vides apparatus which can be operated by the charging machine to clear away substantially all such solids without the expenditure >of any sub stantial amount of hand labor. Altho the herein illustrated and described em« bodiment of the present invention is especially ' Strengthening ribs 20 extend along the outer surface of bottom Iû and side I4 substantially parallel to ends II and I2 of the box. Each of these ribs merges into an offset ñange 2l which extends along the upper edge of side wall Ill. A corresponding oiïset flange 2'2 extends along the suited to use with a charging machine, it will be understood that other devices embodying the in vention may be used with other types of actuating apparatus which are capable of shifting such a upper edge of the low end II of the box and an other similar o?iset flange 22.extends along the upper edge of the high end I2 of the box. The ribs 20 and the adjacent ends of iianges 2I define device to scraping, carrying, or dumping positions and of propelling it during the loading operation. spaces 23 therebetween for a purpose presently ' For example, the attaching means at one end of 25 to appear. It will be noted that the upper edge of side I4 the box herein illustrated may be altered to fit of the box is inclined at an acute angle to the a suitable arm on an automobile, tractor or other bottom Ill of the box and that the low and high wheeled vehicle for use in scraping up solids and ends of the box have integral wings 25 and 26, transporting them to a place where they are to be RO respectively, which extend part way across the dumped. _ ends. A scraper blade 2‘I is disposed on the in The present invention will be better understood clined upper edge oi side I4 of the box and has by those skilled in the art from the following de scription and the drawings which accompany this ends 28 which extend along the ends of the box. Blade 2l has substantially parallel longitudinal specification and in which, Figure 1 is a fragmentary perspective View ., showing a box constituting one embodiment of the invention and adapted for use with an open hearth charging machine; edges, one of which bears against the upper edge of side I4 of the box while the side surface of the blade bears against the inner surface of offset flanges 2I. Similarly, theends 28 of the blade Figure 2 is a top plan view of the box of Fig. 1; rest on the upper edges of ends I I and I2 and bear ' Figure 3 is a cross-sectional view taken on line against ñanges 22. This blade with its ends con stitutes extensions of side I4 and ends II and I2 of the box. Blade 2'I has exterior, integral, yribs 3-3 of Fig. 2; Figure 4 is an elevational View of the right hand end of the box of Fig. .2; Figure 5 is a lefthand elevational view of the box of Fig. 2; and, 29 which extend downwardly below its lower edge, lie in the spaces 23 parallel and adjacentto ribs 20, and may be detachably connected to those Figure 6 is a side elevational view of the scraper ribs, as by bolts and nuts 39.
