WILLIAM DIETRICH, OF CHICAGO, ILLINOIS, ASSIGNOR, BY MESNE ASSIGNMENTS, TO

. CASTING-MACHINE.

To all whom t may concern.' l

Be it known that I, WILLIAMDIBTRICH, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois', have invented a new and useful Casting-Machine, of which the following is a specification.

My invention relates to casting machines for casting rectangular blocks of metal in which the size of the mold for'vthe block can be varied in'size, V and the objects of my improvements are first, to retain the mold 1n a rectangular form; second, to make two sides of the mold movable; third, to provide means for retaining the one movable sidev of the mold in a rectangular position'to the balance of the mold while being moved; fourth, to provide sliding blocks on two opposing sides of the mold to assist in forming one movable side of the mold; fifth,to provide means for securing the different sides of the mold in proper position; sixth,

.to make a neat, cheap and eflicient device 1 and other features to become apparent from the description to follow.

As above mentioned my invention pertains to machines for casting rectangular blocks of metal, the blocks being used inthe art of printing for securing a page of type in to a chasel and for any other suitable purpose.

In the use of these rectangular blocks it has v been found that work is greatly facilitated by forming or casting the blocks Vas fast ,as

they are needed and after they have served their lpurpose to recast them into other blocks of different sizes as again required. This eliminates the necessity of keeping a largestock of blocks on hand'and the ,dan-v ger lof imutilating the blocks by oft han- (lling. l p

To describe lmy invention so that others versal in the art to which it pertains can make and'use the same I have illustrated it on the accompanying two sheets of drawings forming a part of this specification in whichty Y Y Figure l is a planview of a machine em- Fig. 2 is a fragmentary plan view showing one side of the mold moved to an open position; n

Fig. '3 is a cross sectional view 4 taken on line :SW3 of Fig, l; .and l Specification of Reissued Letters Patent. Reissued'oct. 2, 1917- i Original No. 1,104,728, dated .Tuly 21, 1914, Ser1a1 110.804,778, led December 4, 1913. Application `for Y reissue led September 30, 1915. Serial No. 53,453. l

and which preferably has the depending reinforcing flange 6 at its four edges. The table 5 is rectangular in shape and of any desirable size. Secured rigidly tothe top of the table 5, by means of 4screws 7 or otherwise, are the three metal bars 8, 9 and 10, to form three sides or walls of a' rectangle', which rest upon'the table 5, as clearly shown in Fig. 3. The bar 8v being located at the front edge of the table' 5, the bar 9 being located at theleft hand end of the table 5 and the bar 10 being located at the rear edge of the `table 5; Atthe right hand edge ofy the table 5 is' provided va bar 11 forming the fourth 'side of the rectangle formedby the to swing in a horizontal plane. The free' end of the bar 1l is detachably secured in position vagainst the right hand end of bar 8 by a pin 13 fitting snugly into a `hole providedv therefor in the bar l1 and fits snugly to the table 5 and againstthe end of bar 8 so that molten metal cannot escape past the same.

A bar 14 is mounted to slide freely laterally forward and back on the table 5 and has attached to each end by means of a screw o-r pin, 15, a rackbar 16which rackbars eX- tend rearwardly from the bar 14 along beside the bars 9 and 11, through guide-ways 17 provided therefor in the under side ofv the bar 10 as seen .in Fig. 4.

The bar 14 is of such length as to fit be'- tween the bars 9 and 11, and lies parallel to the bar 8, and as said bar 14 is moved toward and away 'from the bar 8 it is retained parallelto the bar 8. The bars 14, 11 and '8 form three sides of the mold into whichA the molten metal is poured, therefore the bar 14 also iits snugly to the table 5 and against the side of the bar 11. The bar 14 is moved as desired toward and away fromv lot allel bars resting on the top of said table, one of the aforesaid-bars being stationary andthe othermovable fromK and toward the same, mechanism for actuating the aforesaid movable bar, and a third bar mounted in proximity to corresponding ends of the other-two bars adaptedto be moved in a horizontal plane, leaving theend` of the table unobstructed for a portion of its length at the ends of the other two bars,'and adjustable guides on the aforesaid parallel bars for determining the length of the block tobecast. v

8. In a casting machine, a table, two parallel bars on said table, one of the aforesaid bars' being stationary andthe other movable from and toward the saine, Ymechanism'for actuating said movable bar, a third bar extending at right angles to the' corresponding ends of the other two bars, said third bar being pivoted at one end thereof to the table and adapted to be moved in` a horizontal plane, adjustable guide blocks mounted kupon the aforesaid parallel bars and a removableA piece abutting said guide blocks -to form the fourth side of the mold or frame formed bythe aforesaid bars. 1

9. In a casting machine, .a table,faV mold formed of two parallel bars arranged on said table, one of said bars being stationary.

and the otherV being movable from and toward thesame,-graduations on said bars, a

third bar extending at right angles to and abutting the corresponding'ends of the parallel bars, guide blocks adjustably mounted on said parallel bars to form the rcompartment of the mold, aremovable piece abut- Y ting against said guide block to form the fourth wall of thel mold, and means including gears and rack bars operating with said Y movable bar to carry it toward and from the stationary bar.

10. In a machine for casting rectangular blocks. of metal, comprising a table, a stationary bar arranged at the front edge of the table and extending above the surface of the table, a bar movable laterally7 across said table from and toward the stationary bar, guide blocks adjustably mounted on said bars, means for engaging said movable bar at two separate points for positively moving it from and toward the lstationary bar and maintaining it at all times parallel therewith, and bars at opposite ends of the aforesaid stationary and movable bars to form a rectangular frame.

11. In a machine for casting rectangular blocks of metal, a table, two bars extending parallel to each other on said table, one of which is stationary, the other movable, a third bar mounted on the table and movable from a position above the table at right angles to the movable bar, to a position away from the top of the table to provide a doorway through which the block .may be r6- moved, guide blocks .adjustably mounted be swung in a horizontal planeaWay-from j the movable bar yto permit the cast-block to be removed, guide blocks adjustably: mount-` ed on the parallel bars, .g and vav removablev piece abutting said guide blocks toform the fourth wall of the mold, and actuating means `connected with the first. mentioned movable bark adapted to move the sameltoward and fromjthe stationary barto main# tainsaid baralw'ays parallel with thestationary bar oppositerthereto.

, 13. In a machine for casting recv angular blocksI of metal, a table, a stationaryvbarl on said table, a: second bar on thel table movable laterally toward and from the. stationary bar, actuating mechanism for the movable bar-arranged to move opposite ends of the movable bar simultaneously in the same direction and to the same extentA so as always to maintain the two bars in parallelism with each other, each of said bars provided with graduations distributed lengthwise thereof, adjustable vblocksv mov,-

able lengthwise of said lbars, and a removable: piece abutting said `blocks torform one lat.

eral wall of the mold, a bar extending at right angles to correspondingendsvof the parallel bars, said last named bar bein pivoted at one end thereof to the table an adapted to swing in a horizontal plane to provide an opening for removing the cast block from the mold.

14:. In a machine for casting blocks of metal, a table, two parallel bars mounted on said table, one of said bars being stationary, the other movable, a third bar extending at right angles to corresponding ends of said parallel bars, blocks adjustablymounted on said parallel bars, and a removable piece abutting said blocks to form the fourth side of a mold ofthe desired length and width to receive the molten metal therein to form the block.
