Figure 1 is a front elevation of-the mold and its supporting disc with lily-improve ment inoperative relation thereto, the cooling devices being shown ;-in dottedlines.

In the form shown, the mold consists, as usual, of cap and body portions se pu'rposeof changing the size of the mold-slot art. The mold is firmly secured in a vertical central stu or journal C, carried by an arm slide D, this 'arrangement permittim the disc to be freely rotated and also allowing it to be moved bodily forward and backward in order to carrythe mold toward and frpm the matrix line/ E represents a'horizontal ejectorblade' slug is brought opposite the ejector, the latter may be advanced through the mold in order to deliver the sin therefrom between the usual trimming devices into the receiving galley.

sents a plate of copper or similar material, secured to the support G, or the guide, D, or both, its front face being flattened and adaptto form an intimate contact with the rear facenf the .mold when the latter is in the "cieciing'position. This cooling plate is slotfor 4 the through,.an d is provided with a passa e h extending around the slot and connecte at the end with a water supply pipe h, and a drainage pipe h, by means of which water or other fcooling fluid' may he flowed continuously through the plate in order to keep the same at a low temperature.

. Under ordinary circumstances, it will be suflicient to make the plate of a size substantiallycorresponding to that of the mold, but it may be enlarged or extended in the'path of ,the'r'nold to any desired extent'in order to prolong the period of contact.

' The plate, if properly cooled, will rapidly absorb heat from the mold and exert a marked influence, preventing the over-heatin'gl orthe irregular heating of the mold. In at er words, it will tend,to keep the temperature of themold within such limits as to prevent excessiveor irregular expansion.

The essence of the invention lies in combiningwith the mold, whatever its form, and without regard to the manner in which it is supported or carried, an external cooling body of any suitable form adapted to contact with the mold.

, It is to be obseryed'that the fluid passages 5 shown herein areclosed, or in other words,

are without joints or openings of any kind adjacent to the mold. his permits of the use of water or other cooling -li uid, as a cooling grnedium without" danger of leakage into the '5? fnold, where its presence would be attended thf'flisastrous results on the admission of the mol-tea meta -When a r orfother gaseous medium is em- Passing now to my improvement, H repreassage-of the ejector thereployed for coolin purposes, small openings may be made in t e plate G to permit the air to esca e and contact with the mold, but under or inary conditions this is not recommended. I

It is to be observed that the cooling means which I have rovided form no part of the gold, but are istinct and independent there- The cooling medium does not enter the mold, and there are no movable joints or openings through which the water can, bv any possibility, reach the surfaces with whic the molten metal contacts.

Having described my invention, what I claim is 1. In a linot e machine, a mold in combination with an independent cooling body ar ranged to contact therewith.

2. In a linotype machine, a slotted mold, an independent cooling body, and means for carrying the mold into and out of contact with said body.

3. In a linotype machine, a slotted mold in combination with an independent coolin body arranged to contact therewith, an

means for artificially cooling said body.

4. In a linotype machine, the combination of a slotted mold, its revoluble supporting disc, and a fixed cooling plate or body H independent of the mold proper and arranged to contact with the rear face of the mold.

5. In a linotype machine, a slotted mold, its rotary supportin disc, aslidd sup the disc, and a mo d-cooling bod from the mold carried with said sli e.

6. In a linotype machine, the combination istinct orting of a slotted mold and an independent external I cooling bodyarran ed to contact with the rear face of the mol said bod being slotted for the passage of the ejector t 'erethrough.

7. The combination of the mold A, the rotarydisc B supporting the same, and the nonrotating cooling body H distinct from the mold arranged to contact with the rear face of the disc. In testimony whereof I hereunto set my hand this thirty first day of October, '1906, in the presence of two attesting witnesses.
