STEREOTYPING APPARATUS.

Patented Aug. 21, 1906.

Application filed February 21,1903. Serial No. 144,550.

cago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Stereotyping Apparatus,

of which the following is a specificatlon, reference being had to the accompanying drawuninterruptedly therethrough.

ings.

My invention relates to stereotyping apparatus, and has for its object to provide a multiple casting-box, thereby making it pos sible to conduct the operation of making a cast in one section of the apparatus while another section is being prepared, thus economizing time, which is of the utmost impor- I accomplish this object in the manner hereinafter specified and as illustrated in the accompanying drawings.

What I regard as new ,is set forth in the claims.

In the accompanying drawings, Figure 1 is a side elevation. Fig. 2 isa section on line 2 2 of Fig. 1. Fig. 3 is a front view. Fig. 4 is a plan view. Fig. 5 is a vertical section on line 5 5 of Fig. 4. Fig. 6 is an enlarged detail, being a partial cross-section of one of the sections of the apparatus. Fig. 7 is a partial side elevation. Fig. 8 is a partial section on line 8 8 of Fig. 7. Fig. 9 is a side view illustrating a modification. Fig. 10 is a horizon tal section on line 10 10 of Fig. 9, and Fig. 11 is a plan view of the parts shown in Fig. 9.

, Referring to the drawings, 13 indicates the base of the apparatus, which carries the lower member 14 of a turntable.

15 indicates a hollow shaft which extends through the base and up through the center of the apparatus, as shown in Fig. 5;

16 indicates the side frames of the apparatus, which are secured to the base 13 and are connected at their upper ends by a crosspiece 17, as shown in Fig. 3.

As best shown in Fig. 5, the shaft 15 passes through the cross-piece 17 the latter serving to hold said shaft rigidly upright.

18 indicates a cylindrical or externally convex core which is mounted upon the shaft 15 and rests upon a pedestal 19, supported by the upper member 20 of the turntable. Balls 21 are preferably provided between the two members of the turn-table to much as the obviate friction. It will thus be seen that the core 18 is free to rotate about a vertical axis and at all times maintains its upright position.

As best shown in Fig. 5, a plug 22 is provided in the shaft 15 near the lower end of the core 18, the object of" said plug being to prevent water in the shaft 15 from flowing 23 indicates a perforation in the shaft 15 below the plug 22. 24 indicates perforations in said shaft above said plug. The object of this arrangement is to provide for conducting water into the core 18 through the shaft 15 and to maintain a circulation therein. The core 18 fits tightly upon the shaft 15, which rotates with it, the ends of the shaft 15 being connected up by couplings 24c 24*, so as to permit the shaft to rotate independently of the stationary supply and discharge pipes with which it connects.

25 26 indicate the cases of the two sections of the casting-box illustrated in Fig. 5. Each of said cases is semicylindrical or internally concave in form, as shown in Fig. 2. The case 25 is provided at its lower end with lugs 27, mounted on a pivot 28, carried by the pedestal 19. Similarly the case 26 is mounted on a pivot 29 by means of lugs 30, said pivot 29 being arranged at the opposite side of the pedestal 19, as shown in Fig. 5. By this construction the two cases are adapted to swing in the same plane, but at opposite sides of the core 18. The pivots are so placed as to permit the cases 25 26 to swing up and overlie the appropriate portions of the core, so that each of said cases forms with half the core a complete casting-box open at the top. The upper edge of the core 18 is beveled, as shown at 31, to form a funnelshaped space, into which the molten metal is poured, and from which it passes into the space between the case and the core. Inascases 25 26 are carried on the pedestal 19, which also carries the core 18, when said cases are in operative position they may be rotated with the core and the shaft 15.

In practice the apparatus is so placed with reference to a source of supply of molten metal that by rotating the casting-box one section thereof may be moved into position to receive a charge, while the other section they lie 5 holds the side strip in position. the pivots 41 and bosses 42 lie in recesses 44 tion,'I provide fiat springs may be opened up for the removal of the plate and preparation for another cast. This construction is illustrated in Fig. 5.

In order to facilitate the raisingand lowering of the cases 25 26, lifting and balancing mechanism is provided comprising a liftingframe composed of side bars 32 and a semicircular cross-bar 33, connecting said side bars at their outer ends, as shown in Figs. 1, 2, and 4. Said side bars 32 are pivotally secured by pivots 34 to the lower portions of the side frames 16, as shown in Figs. 1 and 2, so that when said side bars are in their vertical position they lie adjacent to the side edges of the case which is to be turned down out of operative position, the cross-bar 33 extending around the upper portion of such case. Couriterbalance-weights 35 are provided at the opposite sides of the lifting-frame, said weights being connected to the outer ends of the side bars'32 by cords or other flexible connections 36, which pass over pulleys 37, carried bythe side frames 16. By this construction the liftin'g frame is normally held in its upright position. When, however, the case is'to be turned down to itshorizontal or inoperative position, it rests in said liftingframe and is supported by the counterbalance-weights 35, so that it may readily be moved up or down.

Asbest shown in Fig. 2, the core 18is provided at diametrically opposite points with longitudinal ribs 38 39, which are arranged to coact with the side edges of the cases 25 26 to form tight joints and'prevent the escape-of molten metal at the sides of the casting-box. Between each side edge of the cases 25 26 and the opposite surfaces of the ribs38 39 side strips 40 are-provided, which serve as packing-strips and also to retain the matrix in position, as best shown in Figs. 2 and 6. Said side strips are carried upon pivots 41, mounted ontheside edges of the cases-25 26, as shown in F i .6, the side strips having bosses 42, which fit upon said pivots, as shown. Hand-levers '43 areprovided for rocking the strips 40 upon their pivots '41. When the side strips 40 are in their normal position, flat upon the side edges of the case and project over the side edges of the matrix, binding it in place; butby rocking the lever 43 the side strips may be turned to a position at right angles to that shown in Fig. 6 to facilitatethe removal of the plate and matrix after a cast. This operation is of'course conducted after the case has been turned down to inoperative position, as when it is in its op 39 of the core At this time erative position the-rib 38 or in the ribs 38 39, as shown in Fig. 6. In order to hold the side strips 40 in their different positions when the case is in inoperative posi- 45, which are secured to the side edges of the case, as shown in Fig. 6, and by bearing against flattened surfaces of the bosses 42, as therein illus trated, serve to prevent accidental movement of the strips 40. The cases 25 26 are also provided with end strips 46, which are semicircular in form and are adapted to prevent the escape of molten metal at the lower end of the casting-box and also hold the end of the matrix inplace. As best shown in Fig. 5, the strips 46 are fitted in recesses 47, provided at the lower ends of the cases 25 26, and are heldin position by pins 48, which are fitted in the cases, asshown. The pins 48 also serve as a'means of facilitating the removal of the end strips 46, as will be hereinafter explained. The cases 25 26 are'locked in operative position'by latches 49, provided at the side edges thereof near their outer ends and adapted to engage pins 50, projecting from the ribs 38 39, as shownin Fig. 2.

The entire casting-box is locked, except when'being rotated, by a dog 51, mounted on a rock shaft 52, supported on the base 13, as shown in Fig. 8. Said dog 51 is adapted to enter notches 53 in the members 14 and 20 of the turn-table, so that the upper member 20 is locked against rotation when the dog 51 is in operative-position. By rockin the shaft 52 the dog 51 may be moved out of the notch 53, thereby permitting the turn-table with the casting-box to rotate. The dog 51 is normally held in operative position by a spring 54, mounted on the shaft 52, one end of said spring being secured to-the shaft and the other end to the base, so that when said shaft is rocked the spring 54 is twisted. In order to rock the shaft 52 and unlock the turn-table, foot-levers 55 56 are provided, arranged at opposite sides of the machine, as shown in Figs. 3 and 8, said foot-levers being arranged so that downward pressure on either of them operates to rock the shaft 52 to carry the dog .51 out of operative position. This isbest secured by mounting the footlever 55 directly upon the shaft 52 and keying it thereto and providing said'lever with an arm 57, projecting at an angle thereto, said armbeing connected by a link 58 with an arm 59,projectin at an angle to the lever 56, which is mounte on apivot 60, as shown in Fig. 3. The arms 57 and 59 extend in opposite directions, as shown. The result is that downward pressure on either of the footlevers rocks the shaft52 in the direction indicated by the arrow in Fig. 3, and consequently unlocks the turn-table.

61 indicates an arm carried by'the shaft 52, said arm being so-placed as tolie under and adjacent to the head of the pin 48 when either of'the cases 25 26 is in its horizontal position, as shown in Fig. 5. By this arrangement when the-shaft 52 is rocked to unlock the turn-table the-arm 61 is thrown upward, pressing the pin 48 inward and forcing p lies, thereby releasing the matrix to permit its removal from the case. A spring 62 is provided between the head of each pin 48 and the adjacent surface of the case to press the pin outward and restore the strip 46 to operative position when released from the pressure of the arm 61.

From the foregoing description it Will be seen that in the form of apparatus described in which there are two sections to the cast ing-box, either of said sections may be swung into position to receive a charge and that while the cast is being made in such section the case of the other section may be turned down to be put in readiness for the next cast. A single lifting or balancing device suffices for the entire apparatus.

In Figs. 9, 10, and 11 I have illustrated my improvements as applied to a casting-box having a larger number of sections; but the general features of construction are substantially the same. In the form of apparatus illustrated in said figures the core instead of being cylindrical is provided with four semicylindrical sections 63, 64, 65, and 66, respectively, all carried by and connected with a central support 67, which is pivotally mounted in the manner already described, so as to rotate about a vertical axis. Similarly cases 68, 69, 70, and 71 are provided for said coresections, respectively, the different cases being adapted to swing down to inoperative position in the manner described. 72, 73, 7 4, and 75 indicate the pivots of the different cases, as shown in Fig. 10, all of which are carried by a pedestal 76, corresponding to the pedestal 19 and similarly mounted 011 the upper member of a turn-table 77. A single lifting device is provided similar to that already described, the parts of which are indicated by the same reference-numerals The locking devices are also the same except that, as shown in Fig. 10, the turn-table is provided with four notches 58 instead of two. If desired, by providing a plurality of lifting devices and arranging to supply molten metal to a plurality of casting-box sections at the same time the capacity of the apparatus could be multiplied; but for ordinary purposes a single lifting device in connection with means for supplying molten metal to a single casting-section at a time is sufficient.

It will be understood that while I have de scribed specifically the embodiment of my invention illustrated in the drawings, I do not wish to be restricted to such specific details of construction except in so far as they are particularly claimed, since my invention includes the generic features set forth in the broader claims. Moreover, my improvements are not restricted in their application to apparatus for casting stereotype-plates except the end strip 46 in the recess in which it l I in so far as such limitations is expressed in the claims.
