n -rm rot PVRESYSES wxrn Hmm'e n Application filed l fliareh 12, 1930. Serial No. 435,282.

My invention pertains to platens for presses withh ating coils therein.

Myinvention'is used in connection with presses which have heatingc'oils in the pres- 5 sure plates or heads of thepresses, sothat when molds are pressed between said plates or heads, thatthey become heatedbythesteam passing through the said'plates or heads. It is sometimes o desirable in order to press a lo larger number of parts to be moulded, to have relatively loosely fitting platens which may be positioned between the pressure plates or heads of the press and to have these platens with heating coils therein, the steam passing by a flexible hose connection from the press heads to the platens, and molds can be placed between the platens and between the platens and the pressure heads, thus increasing the capacity of the press. Multi-pressing with 29 floating platens as described above is in use and common practice.

My invention pertains to an improvement in the type of platens used and in the method of making such platens with heating coils 2; cast therein, instead of casting steam passages with intricate core work or drilling steam passages into the solid metal.

Another object of my invention is in the arrangement of the heating coils'in the plat- 30 en by which a circulation of the hot steam i is paralleled by a circulation of the cooled steam which is being exhausted from the particular platen and thus give a more even tem perature over the whole of the platen. In

platen so that the hot live steam circulates, from the peripheral portion of the platen in a spiral like pipe tothe center of the platen and then flows out through a similar spiral type of pipe but in opposite direction; the i 59 ingoing and outgoing steam traveling oppothe prior practice it has been more or less:

common to form the platens out of a metal c sitely in parallelpipes which are adjacent each other. I 1

'Another object of my invention makingthe -coil for carrying: the steam and imbedding this in the platen in a casting operation the coil of pipe'being suitably supported in i the mold.

Another detailed object of my invention is making the coilof pipe in a plurality or parts, there'being one part havinga'somewhat spiral type of coiling for carrying the steam" inwardlyto thecenter; this'if'the platen is' square, having sides parallel to the sides of the platen and a second coili designed to carry thesteamfrom the center of the plat en outwardly. The pipe oi these two coils are so spaced that the 'coils may be fittedto' gether and a connecting short section of pipe welded at the center of the coils making therefore a continuous-connection. The sin-- gle coil'thus 'so-forme'd is placed in the mold coil."

My invention is illustrated in panying drawings, in Which,

Fig. 1 illustrates a plan of the coil of pipe carrying the steamifro'm the outside to the inside of theplaten; j l 'Fig; 2 is aplan'of he coil of pipe carrying the steam from the inside to'the outside of and the metal of the platen'cast' about such" the platen;"' a l r v FigI'B'is a plan of the two coilsof Figs. 1 and 2, connecte'd'together with suitable "bracis a plan of the platen; 7 -Fig'. 5 is an end elevation of the platen. 1

In the drawings, the coil for theinfl owing steam from the exterior to the interior of the platenis'indicatedby'the numeral 11, having an" intake end 12, the steambeing designed to flow' inthje direction of the arrow 13. If the platen is 'squ'are the coil 'is formed with straight sections joined by curved bends. At the "center there is sharply curved-section 14, terminating at 15;

' The coil for the outgoing steam designated" the accom center, outwardly. There are lugs at the sides of the platen'havingholes 26 therev through. .These holes are to accommodate end 20. In this case if the platen is square the coil is made of straight sections of pipe joined by corner or angle bends and in any case the coils 11 and 16 shown in Figs. 1 and 2 .are so made as to interiit. These coils when so made are interfitted and the ends 15 and 17 at the center are connected by a short designated at 24. These illustrations show; the center line of the pipe sections of the coil and indicate the manner in which the steam flows towards the center and then from the guide rods for the platen. There aresmall transverse holes27 drilled in the lugs to be used if morethan one floating platen is to be hung-.011 the press.

on the coils, it is-usual to cast the device in at the end 12 of the coil and passes inwardly, following the direction of the arrow 13. The r e the outflow is of a-lower temperature from steam follows the zigzag path of the platen,

the vertical position with the intake and discharge ends of the pipes of the coil at the bottom of the mold.

It will be seen thatthe hot steam enters hot steam therefore circulates practically the whole of the platen adjacent the periphery and then by succeeding loops of the, coil, travels towards the center. By the short section of pipe 21 thesteam is transferred from the inflowing coil to the coil for outflowing steam and flows reversely outwardly follow-' ing the path'of the arrow 19. The steam in that of the intake, on account of the loss of temperature in heating the platen and the articles to be pressed, but on'account of the outgoing steam pipe sections being spaced between the inflowing' steam, a relatively equable temperature of the platen is obtained from side to side and from the center to the outerperiphery. This gives a materially better uniform heating effect than where the in'which latter case the platen is usually hotter at one side thanat the other. VThe materials used in making the 'coil in the platen are preferably steel-tubes, as such tubes may xbe bent more readily and give sufiicient strength to withstand steam pressure, should a high pressure be desired and these pipes are cast in a semi-steel. Thus the platen as a whole has a semi-steel body with steam pipe coils formed therein.

Various changes may be made in the prin- In casting the metal ciples of my invention without departing from the spirit thereof as set forth in the description, drawings and claim.

I claim A platen for presses comprising two pipes, each coiled into a spiral, each spiral having adjacent sides at right angles one to the other, the connecting corners having curved bends,

said pipes being positioned in-the same plane,

therebeing spacers for spacing the pipes, the inner ends of each pipe having a semi-circular bend, the ends of said bends being connected bya straight pipe section, said pipes being arranged with the sections of one pipe xbetween parallel sections of the otherpipe,

one of said pipes being for an inflowing fluid and the other for an outflowing, the inlet and outlet pipes being parallel in all sections except at the semi-circular bends, the exposed ends of said pipes being contiguous, said pipes being embedded in a cast metal body. I

In testimony whereof I have signed my name to this specification. I
