TYPOGRAPHICAL CASTING-MACHINE.

Specification of Letters Patent.

Application led May `1, 1913. Serial o. 764,744..

.To all whom t may conce/11n Be it known that I, Davie S. KENNEDY, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented certain new and ixseful Improvements in Tvpographical Casting-Machines, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to typographical casting machines, such for instance as linotype machines of the general character' represented in Letters Patent of the United States, No. 436,532, to O. Mergenthaleiy wherein a composed line of matrices is presented momentarily to the face of a slotted mold in order to form type characters on the edge of a printing slug cast therein. lhen these machines are Operated under certain conditions, the molds become unduly heated by the molten type metal delivered thereto, and means are therefore provided to regulate their temperature within the proper limits by the use of cold water or other cooling mediums, as set forth in my previous Letters Patent, No. 959,755. May 31, 1910. In the specific construction illustrated in the said patent, the mold disk is mounted to rotate about a hollow stud. to which the water or other cooling fluid is supplied through suitable piping. rdinarily, this piping connects with the customary source of water supply, or the water is forced therethrough. by a pump from a reservoir. In the present instance I preferably employ a closed and continuous system including a reservoir, and rely for circulation upon the thermic currents induced by the heat of the mold.

' In such machines, also, the mold carrier is mounted on a reciprocating slide, and as the reservoir is stationary, I have devised means to permit this relative movement Without the interruption of the piping, or the danger of its disconnectionand the leakage resulting therefrom. To this latter end I provide the piping with flexible or extensible members at suitable points, and in this way permit the said relative movement.

In the accompanying drawing, I have illustrated my invention in preferred form and by way of example, and as adapted to the ordinary linotype casting mechanism. However, many variations and alterations may be made therein, and in its mode of application, which will still be comprised within its spirit. Generally speaking, I desire it to be understood that I do not limit myself to any specific form or embodiment, except in so far as such limitations are speci- `tied in the claims.

The drawing is a perspective view, partly in section, of Ia portion of the casting mechanism, having my improvements embodied therein.

As set forth in my previous Letters Iatent, the mold'wheel or carrier A is equipped with. the `slotted mold B and is mounted upon the reciprocating mold slide C, `in such manner that the mold may be moved laterally toward and from the composed line, not shown herein. Also as in said Letters Patent, the carrier A is arranged to rotate about the large, hollow stud E, through which water or other equivalent cooling medium is aured to circulate from the pipe system In the present instance, the pipes F, F are stationary and lead respectively from and to the reservoir Gr, which is also stationary, and is mounted in any desired manner, preferably Within the column or base frame G of the machine.` The hollow stud E is provided with the inlet and outlet tubes II and H', which necessarily partake of the reciprocating movements of the mold slide C. The tubes H and H are respectively connected to the stationary pipe branches F and F by the flexible members J and J This yielding or flexible connection permits the relative movement of the mold carrier C and the hollow stud E, with reference to the stationary reservoir and piping, without the danger of interruption or breakage, and the consequent leakage of the cooling medium so disadvantageous in connection with high temperatures `and apparatus of this description. Also, as above indicated, the chambers in the stud E, the tubes I'I, I-I, the members J, J', the pipes I?, F', and the reservoir G, constitute a closed and continuous system, wherein the circulation is secured through the thermic currents induced by the high temperature of the mold B.

As previously stated, I have shown my invention in preferred form and by way of example, but many variations may be made Thus, the points of application of the yield ing or flexible connections may be varied, or other equivalent devices, such as sliding Patented ct. 26, 1915. i

Itherein without departure from its scope.

joints, or the like, may be substituted therefor. Or the arrangement and location or" the yelements of the closed system maybe suitably changed. These and other modifications will l, suggest themselves f to those skilled in the art.

y Having thus described my invention, its construction and mode of operation, what I claim and desire to secure by Letters Patent of the Unitedy States, is as follows:

'1. In a typographical casting machine, the combination of -a` mold adapted to contain f molten metah and'means for cooling the Vmold and its contents to prevent 'overheating thereof due to the successive castingoperations,` said coolingr means including a tank or reservoir to contain the cooling medium, a cooling chamber, and a pipe system connecting the cooling chamber and reservoir so that the cooling medium may circulate freely back and lforth between the two, and the said cooling' chamber being arranged in proximity to the mold and within the heatingI zone yof the molten metal therein so Copies lof this patent may be obtained. for

that the heat thereof will eiiect and control the circulation of the cooling medium which, in turn, maintains the mold and its contents at a uniform temperature.

2. In a typographical casting machine, the

.. combination of a mold mounted to reciprotem comprising sections which are flexibly connected to permit the reciprocating movement of the cooling chamber with the mold. In testimony whereof I have aiiixed my signature in presence of two witnesses.
