Specification of Letters Patent.

Application filed April 7, 1919. Serial No. 288,147.

To all whom it may concern Be it known that I, BYRON K. Ln Gnome, a citizen of the United States of America, a

resident oi- Efl'ingham, in the county of Effingham, State of Illinois, haveinvented certain new and useful Improvements in.

Apparatus for Making Stereotypes, of which the following is a fu 1, clear, and exact de-' scription, reference being had to the accompanying drawings, forming a part of this specification.

My invention relatesto a self-contained stereotype casting apparatus having therein all of the essentials of a stereotype molding operation and so constructed as to provide for the quick and easy transfer of molten metal from a melting pot to the stereotype casting box, thereby making it possible to produce electrotypes at the maximum of speed. Furthermore, the apparatus is so constructed as to provide for instant assemblage and separation of the elements of the apparatus, sothat the parts maybe asembled and disassembled without the use of connectin appliances requiring time for their manipulation.

Figure I is a top pla'n view of my stereotype making apparatus, portions of the melting pot and casting box being shown broken out and in section.

. Fig. II is a side elevation of the apparatus which preferably includes inclined rear members 1 and front members 2, connected by upwardly extending joined arms 3 prov1ded with a keeper 4. 5 is a burner supported by the stand A, said burner bein of any suitable construction for supplying eat to melt the metal used in making stereotypes.

6 designates a tilt table pivoted intermediate of its ends to the upper portion of the stand A by trunnions 7. Said table is adapted at one time to occupy a horizontal position, in which its front end rests upon a ledge 3 at the upper end of the arm 3 of the stand A, as seen in Fig. II, and at another time occupies a tilted or inclined position, as shown in Fig. III. When the tilt .the separable sections of which are held asser'nbled in any ordinary manner. The casting box, which is intended to hold a matrix as usual, is provided at one of its ends with a mouthpiece 10 through which molten metal is poured to enter the box, said mouthpiece having formed thereon or secured thereto side lugs 11 of utility to be hereinafter mentioned. l i

12 designates a melting pot of e g shape, as shown, or of any other suitable shape. This melting pot occupies an opening in the forward portion of the tilt table 6 and is provided with a top opening through which metal to be melted may be introduced and whichis normally closed by a door 13. At the rear end of the melting pot is a mouthpiece 14 with which the mouth-piece 10 on the casting box 6 registers when the casting box and melting pot are in position upon the tilt table 6.

At each side of the melting pot 12 is a side lug 15 adapted to seat within and be held by an L-shaped arm. carried by the tilt table 6, the lugs 15 being located in front of the legs of said L-shaped arms, and the wings of said arms extending forwardly from said lugs, thereby preventing either rearward or upward movement of the melting pot when the lugs 15 are in engagement with the arms 16.

The melting pot 12 is also provided with rearwardly extending hook arms 1 having vertical fingers 19 spaced from each other a distance greater than the width'of the mouthpiece 10 of the melting pot 9, and adapted to be engaged by the side lugs 11 carried b said mouthpiece. By engaging the side ugs 11 on the mouthpiece of the casting box with the fingers of the hook arms 18, the mouthpiece of the casting box is held in engagement with the mouthpiece .of the melting pot.12, and to make such engagement firm the forward faces of the hook arm fingers 19 are inclined, as seen at 19, and the rear faces of the lugs llare also inclined, thereby providing a wedging action between said lugs and fingers which results in the adjustment of the smooth end ing downwardly from the rearward projecfaces of the mouthpieces and 14 into close contact.

The melting pot 12, in addition to being i detachably connected to the tilt table 6'by the engagement of the 1ugs15 with the L-- arms 16 on the table, is also placed mengagement with said table by a lug 17 extendtion of the pot which carries the hookarms 18. The melting pot is therefore engaged with the tilt table at three points, two of which prevent rearward movement of the pot on the'table and. the other of which holds the pot from lateral movement.

In the use of my apparatus,the melting pot is readily slipped into place on the tilt, table 6 by disposing it in the opening 1n the forward portion of the table and moving it 'rearwardly, so that the side lugs 15 w1ll become engaged with the L-arms 16 and the lug 17 will drop into the opening provided therefor in the table. The melting pot having been securedin place, a casting box having the described mouthpiece is so presented to the melting pot as tocause the side lugs of its mouthpiece to ride downwardly along the inclined forward 'faces of the hook arm fingers 19 until the two mouthpieces 10 and 14 arebrought into registering relation and held firmly assembled to avold leakage of metal through the joint between the mouthpieces. The operations just described are performed while the tilt table is in the horizontal position shown in Figs. I and 11. Assuming now that molten metal, heated by V the use ofthe burnerv 5, is present in the melting pot, the next act. of the operator is to release the.latch 8 and tilt the table 6 from the horizontal position to the inclined position shown in Fig. III. By so tilting the table the melting pot and the casting box supported thereon are placed in inclined position, the molten metal passing from the pot to the box through the mouth pieces 14 and 10, with resultant casting operation.

. The tilttable'is then returned to a horizontal position prior to the separation of the M casting box from the melting pot. To per mit the ready separation of the casting box from the melting pot'the lower portions of the lugs 11, carried by the mouthpiece of the casting box, are rounded or cut away, as seen at 1-1, so that the rear edges of these portions of the lugs are separated from the opposing portions of the hook arm fingers l9 engaged by the remaining portions of the lugs. These cut away portions'of the lugs 11 enable the operator to tilt the casting box casting boxes may be employed in the use of my apparatus, it being essential only'that the mouth piece of the box, irrespective of the size of the box, be of a size and shape to fit the mouth piece of the melting pot.

' I claim:
