Q may Patented Mar. 18, 1930 PATENT OFFICE VINCENT TOIPE, OF SHARPSVILLE, PENNSYLVANIA INGOT-MOLD FLASK Application filed February 25, 1929. Serial No. 342,360.

My invention relates to certain new and useful improvements in flasks for casting ingot molds, and important objects of the invention are to provide a flask of the character described, which will expedite ingot mold casting operations, which embodies novel means facilitating the removal of the cast ingot mold therefrom, and which may be repeatedly reused for ingot mold casting 10 operations.

Further objects of the invention are to provide a device of the class stated which is simple in its construction and arrangement, strong, durable and efficientin its use, and

15 comparatively inexpensive to manufacture,

maintain and operate.

With the foregoing and other objects in view which will appear as the description ro'ceeds, the invention resides in the comgo ination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the vention hereinafter disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

In the drawing wherein like, numerals of reference designate corresponding parts throughout the several views ingot mold flask constructed in accordance with the invention.

Figure 2 is a top plan view thereof. Figure 3 is a sectional view on line 3--3, Figure 2.

Figure 4 is a sectional view on line 44, Fi ure 2.

igure is a plan view of a clamp member. Figure 6 is an enlarged view of the releasable connecting bolts.

Figure 7 is an enlarged View of the gate block.

Referring in detail to the drawing 1 denotes the hollow body portion of my imroved flask which is vertically divided into our separate complemental quarter sections, respectivelyindicated at 2, 3, 4 and 5. The sections 2 and 3 are identical in construction and

sections

4 and 5 correspond in. construction.

Figure 1 is a side elevational view of an The periphery of each of the

sections

2, 3, 4

5, is provided with three vertically disposed, integrally formed, re-enforcing ribs, respectively indicated at 6 and 7 and with four horizontally disposed, circumferentially extending, re-enforcing ribs, respectively indicated at 8, 9, 10 and 11, which are merged at intersections with the

vertical ribs

6 and 7. The vertical ribs 6 of each of the

sections

2, 3, 4 and 5 are disposed at respective sides thereof, while the other vertical rib 7 is disposed centrally between the associated ribs 6. A staple 12 is fixed adjacent to each end of the ribs 7 to facilitate connections for handling

independent sections

2, 3, 4 and 5.

The adjacent ribs 6, of the sections 3 and 5, and of the

sections

2 and 4, are respectively joined together with a plurality of bolts 13, which extend horizontally through registering apertures 6 provided therefor in opposed ribs 6 of the sections 3 and 5, and of the

sections

2 and 4.

Each of the bolts 13 is secured in position by a fiat wedge 14, which extends through a slot 15 formed adjacent to one end of the bolt 13. A retaining bolt 16 extends through the lower narrow end of each of the wedges 14, to prevent the latters dis-engagement from its bolt slot 15 unless desired.

the

sections

4 and 5, securely together; The

opposed sides of associated ribs 6 are respectively provided with dowels and with corresponding apertures 31 to facilitate the positioning of the

sections

2, 3, 4 and 5, relatively to each other.

When the bolts 13 are secured in the adjacent ribs 6 of the sections 3 and 5, and in the opposed ribs 6 of the

sections

2 and 4, and when the clamps 17 are in their securing positions on the adjacent ribs 6 of the sections 2 and 3 and on the opposed ribs 6 of the sec--

tions

4 and 5, in the manner stated, all of the

sections

2, 3, 4 and 5 are properly joined together to constitute the flask body portion 1 having a large vertically extending flask opening 18, which is open at both ends and gradually and slightly increasing in area from its upper to its lower end.

The sections 2 and 3 are formed to combinedly form a vertically extending, laterally disposed, offset ortion 19, in which the vertically extending pouring gate 20is provi'ded. The lower end of the latter communicates with a horizontally extending recess 21, which is disposed adjacent to the lower end of the body portion 1 and communicates with the flask opening 18.

The recess 21 is adapted for the reception of a replaceable refractory gate block 22. The latter is formed with a passage 23 which communicates with the flask opening 18 and. the vertical pouring gate20.

When preparing my improved flask for pouring the metal, a gate stick 24 is positioned centrally in the pouring gate 20 with the lower end thereof inserted in the communicatin end of the block passage 23. Suitable sand is then tamped around the gate stick 24 and the latter withdrawn leav ing a continuous pouring passage through the tamped sand which communicates with flask opening 18, through the inter-communicating block passage 23. By this construction the metal, during the pouring operation, Will never contact with ordamage the pouring gate 20 and block recess 21. ()f course, before each casting operation it will be necessary to resand the pouring gate 20' and to replace the gate block 22. The pouring gate 20 is further provided with a plurality of vents 25 to dissipate potential gases created during the pouring operation, which would otherwise tend to disrupt the sand structure in the pouring gate 20.

A pair of opposed recesses 26 are formed at the upper end of the inner periphery of the body portion 1. Each of the recesses 26 is combinedly formed between respective

adj acent sections

2 and 4 and the sections 3 and 5. The recesses 26 provide for casting correspondingly shaped lugs upon the ingot mold being cast, to facilitate its handling.

The handling of the ingot mold being cast is further provided for by combinedly forming another recess 27 between the

sections

2 and 4. A lifting loop 28 is adapted for being properly sanded in the recesses 27, so that the free ends of the former are integrally em? bedded in the ingot mold, being cast, during the casting operation.

Another recess 29 is combinedly formed between these same sections 2 and4. The recess 29 is comparatively shallow and is intended to be properly sanded to receive a suitabie impress providing identifying characteristics on the ingot mold being cast.

All surfaces of the body portion 1, including the surface of the flask opening 18, are properly sanded before each casting operation, so that the damage to the flask is reduced to a minimum, thereby permitting of the use of the same flask for repeated casting operations;

During ingot mold casting operations, the usual sanded core bar, (not shown) is, of course, positioned in the flask opening 18, so that the ingot mold casting acquires the conformation of an ingotmold of regulation configuration.

In releasing the cast ingot mold from my 1mproved flask, the wedges 14 are driven up wardly to slightly release the bolts 13, and t clamps 17 are removed entirely. Such release of the bolts 13 willallow a slight disengagement of the connection of the sections 2 to 4, and 3 to 5, while the removal of the clamps 17 will permit of the parting of the connections of the sections 2 to 3 and 4 to 5. The release of the

sections

2, 3, 4 and 5, in the manner stated, will facilitate and expedite the removal of the cast ingot mold from the flask body portion 1.

The present invention provides a most efflcient flask for facilitating and expediting ingot mold castin operations in an economic manner.
