To all whom it may conceive;-

Be it known that I, Ann'xnnnnn S. CAPE- HART, a citizen of the-United States, and a resident of Bismarck, North Dakota, have inyented certain new and useful Improvements 1n Type-Line-Gasting Machines, of which-the followingisa full, clear, and. exact specificaliill I This invention relates to type-setting and' line-casting machines of that class wherein lines of movable female type or matrices or one'side of a mold and molten metal introduced at the opposite side for the purpose of castingslngs or type-high printing-bars havmg at one. of their edges relief-type the coun- 4 terparts of the intaglio characters or of the impressed "matrices, In machines of the charactor alluded to the casting mechanism -nsually comprises a casting-pot heated by the flame from 'a burner and having a plunger by which molten metal is forced through the month of the castingotinto the mold.

The chief objects 0 my'present invention are to avoid the presencecf a flame for heating the casting-pot, which unduly heats surrounding or other parts of the machine; to maintainlt-he metal in the casting-pot at the required temperature without nnduly'heat ing surrounding parts of the machine; to convey the molten metal fromja receptacle or source of supply independent of or separate from the line-casting machine to the casting:

- pot, by-which 'itis properly delivered at prede- 3 5 termined intervals and in the'reqnired quantities into the mold; to maintain the metal in the proper molten condition in transit from the remote receptacle or source of supply to the casting-pot rtqprovidemeans whereby a singlereceptacle or source of supply may be utilized to supply molten metal at the proper temperature to the casting-pots of a group of line-casting machines; to render the lin e-cas tjng machineles's disagreeable to the operator,

-and to secure regularity inthe product of the mac.

allyheat the casting-pot of thejlinecasting machine and connect it,through the medium of an electrically-heated pipe,- tube, or conduit,with a melting pet,receptaele,or vessel losated more orless remote from and independ;

ent of the line-casting machine, and heated by electrical or any other desired means.

The construction and arrangement of the various parts for carrying my invention into 'elfect may be widely varied, and therefore the illustration in the accompanying drawings is only designedas typical of many diiferent constructions and arran gemcnts that may be e1nployed. I p

In the drawings, Figurel is a sectional side elevation showing my invention in operative connect-ion with the mold of a monoline type setting and casting machine. Fig. 2 is a diagrammatical view indicatingseveral lin e-casting machines having' their casting-pots supplied according to my'invention, and Fig. 3 is a'detailview showing the preferred form of casting-pot.

I intend my inventionfo'rany type or linepotfor casting solid lines of type or type-high casting machine having a mold and casting printing-bars bearing relief-characters at one V edge which are the" counterparts of lines of movable female type or lines of impressed intaglios presented to and closing one side of the mold. I have, however, illustrated my'invention in connection with, a casting-pot and a mold similar to those used in the monoline type setting and-casting machine. v

In the drawings, the numeral 1 indicates a casting-pot, 2 a mold, and 3' one of several matrix-bars assembled in line at the side of the mold opposite the side presented to the casting-pot. The casting-pot, which is arranged inoperative connection with the mold, is preferably composed of a cylindrical casing containing a plunger-4 and constructed with a threat 5, rising from the lower end of the cas ing'and providedjwith a perforated deliverymonth 6 of a length coextensive with the length of the mold-cell in which the slug or The c 'linr type-high printing-bar is cast.

drical casing is also constructed near its lower end with a lateral inlet-orifice 7, which in any suitable manner is placed in communication A with a metallic pipe or tube 8, leading toand To aecemplisii'the objects stated, I electric.

communicatin with a melting pot or vessel erwise. Thamelting-potis isolated'orlocated at a point remote from and -is'independent. of

the typesetting and linewa'sting machine,

and preferably the melting-pot is arranged at a higher level than the casting-pot in the machine,'so that the molten metal will fio'w by gravity casting-pot.

The pipe or tube is electrically heated by properly coiling a naked'wire conductor 12- thereupon'a-nd connecting the same with a dynamo or other source of electricfluid. The casting-pot is also heated by an electric conductor 13,'coiled around the same and adapt-' ed to convey an electric current. for heating the pot. The electric conductor for heating the pot may be a part of or it may be independentof the electric conductor for heating the pipe ortubeleading etc the melting-pot. The electrical appliances 'for'heating the pipe ortube and-the casting-pot may be of any construction and arrangement suitable 'for the purpose in. hand, and therefore I wish it understood that my invention comprehends the electric heating of the pipe or tube and the casting-pot in any manner which will socure-the desired results of maintaining. the metal in the pipe or tubeand the pot in a f molten condition and avoiding the use of a flame from a gas or other burner in the linecasting machine. 4

, The plunger 4 of the casting-pot serves to open and close communication between the pot and the pipe or tube through the orifice '7. When the plunger descends, the com.-

, munication between the pot and the pipe or substantially in tube is closed, and the metal in the pot is displaced and forced through the threat 5 and delivery-mouth 6 into the mold-cell, where the printing-bar is cast. f When the plunger ascends,'the metal in the delivery-mouth and threat, is drawn by suction toward the casting-pot, and the communication between the latter and the pipe or tube is established for supplying the pot with-a quantity of metal proportion to the quantity which was delivered into the mold. The

melting-pot is designed to "communicate;

through the medium of aplurality of electrically-heated pipes or tubes, with-the cast- 4 ing-pots of a group of line-casting machines, whereby it is possible to'supply all the castto the mold ing-pots from a single vessel in which the metal .is melted.

The casting-pot may in practice be made movable, so that its'mouth may be moved up when the printing-bar is to be cast, or the 'mold may move up to the month. of the casting-pot, or both parts may be made.-

movable with relation to each other.

The casting-pot and the whole or a part of thepipeor tube are jacketed, as at .14,'in any .rial to prevent undue radiation of heat.

. In-Fig. l-the cylinder of the casting-pot 1 is arranged within an outer cylinder around suitable manner with non-conducting matewhie'h the electric conductor or: wire 13.'is wound, and the whole is inclosed in a casing 16. This form of casing is similar to that. used in the monoline-casting machine.

through the pipe or tube to the .the casting-pot.

v In Fig. 3 1 illustrate the preferred form of casting-pot, wherein the electric heating-coil 13 is placed directly upon the cylinder in which the plunger 4 operates and extends along the throat 5 of the pot to a point in casting-pot shown in Fig. 3 is designed to be jacketed with any suitable insulating ma: terial.

The delivery of the molten metal to a cast- -ing-pot having a force-pump or its equivalent and a delivery-mouth constructed to cooperate .with a mold'designed to cast a printing-bar or a solid line of relief-characters is important in that the casting pot is constantly supplied and possesses the characteristics which are essential for the practicable production in a type-setting and line-casting machine of comparatively long slugs or printjuxtaposition to the'delivery-mouth 6. The I ing-bars, each having at one edge a line of .usefulresu'lt with the mol used in such machines andcannot' proper y supply the req-- uisite quantity of molten metal to a mold designed to cast a solid line bf type represent ing composed matter.

My invention is particularly-useful where the mouth of the. casting-potis of considerable leugth to cast comparatively long lines of .type. In such case it is difiicult to mamtain the throat and its delivery-mouth at the required temperature, and this cannot be effected by ordinary means without unduly heating parts of the machine which it isde-f sirable to avoid heating. If the metalflowing through the throat and its delivery-mouth 1s not properly heated, imperfect printing-oars are obtained because thenietal is too cool when the castingjs made. w w

The electric heating devices render it'pos-n sible to maintain the required temperature at the throat and mouthof the casting-pot without unduly heating other parts of, the machine and without theodor and otherannoyances' incident to ordinarymethods of heating While I prefer to heat the casting pot solely by electrical means, such as described and shown, I wish it understood that the pot may be heated partly by electrical means and part y by the flame from a burner. In such case the throat'and'mouth of the pot should be heated electrically. I consider, however, the heating partially by an electric current and partially by a gas or other burner under sirable and inferior.

a mold, a melting-pot and connectedwith the I may wind the electric wires or conductors, around the. inside of .1, and around the outside of the inner cylinder or well and the outside of the throat and the outer cylinder, Fig.

mouth.

Having thus described my invention, what I claim is- 1. The combination with the mold of atypeline-casting machine, constructed to cast a printing-bar bearing a line of reliefcharacters, of an electrically-heated casting-pot 00- operating with the mold, means for causing metal to flow from the casting-pot into the arranged remote from said casting-pot and independent of, or sepa-' rate from the line-casting machine, and an electrically-heated conduit leading from the melting-pot and coin m u nicating with the casting-pot.

2. The combination with the mold of a typeline-castin'g machine, constructed to cast a printing-bar bearing a line of relief-characters, of an electrically-heated casting-pot 00- operating with the mold and having a lateral orifice in its side, a melting-pot arranged remote 'from the casting-pot, an electricallyheated conduit leading from the melting-pot lateral orifice of the casting-pot, and a plunger which passes said orifice and thereby opens and closes com nurnication between said conduit and the castingpot through said lateral orifice, and serves to force the metal to the mold.

3. The combination of amold, a casting-pot heated casting-pots for displacing the metal therein and forcing it to flow into the mold.

4, The combination of a group'of line-casting machines, having molds and electricallycoiiperating with the molds, with a melting-pot independent of, or separate from the line-casting maehihe and having a plurality of electrically-heated connections with the casting-pots of said linecasting machines.

5. The combination with the mold of a typeline-casting machine, of a casting-pot having an electric heatingdevice applied about its throat which delivers the molten metal into the said mold, a melting-pot arranged remote from said casting-pot and independent of, or separate from the a conduitlcading from the melting-pot to the casting-pot, substantially as and for the purposes descrihcd.
