The invenion will be understood by felgen ence to the annexed dmwing, in which Figune l is e cross section of the entire heating and cooing-platej-aken on line -l in Fig. 5, Wien a record-mold ettachedthereto; Fig. 2 shows the vuppei' side of the bese; Fig. 3 is a, cross section o e portion of the Tosse and top-seat taken across one of the pockets on line 3-3 in Fig; Fig. 4 is e portion of the bese and top-seat teken on line 4 4 in iig. 2; Fig. 5 Ashows he upper side of ehe top-sent; Fig. 5 is e. section oi the top-seat on line 6 6 in Fig. 5; Fig. 7 is e. top View, and Figz e side View oi" the paritlon for ehe inkt-pocket.

Figa 9 o, top viem and Fig. l0 a side View of the partition for ihe outlet-pocket.

The base a., es shown in 3 and is formed of e thin isk with integral ribs o upon iis under side to rest upon the bedpinte or pieten.

Radial pockets c and d are formed in the upper side'of the base," the youter end of the inlet-pocket being connected with aninlet f and the outer endoftheoutlet-pocketfconnected with an outlet-pocketjf. Themargin of the base is provided with an upwardly projecting ring g to center the top-seat thereon. The said `seat is shown-With the top-portion Zz, of the body made relatively. thin, and a series of concentric'channel's' c" formed upon its under side by concentric ribs e which are -tted to rest upon the lower portion k2 wedge-shaped, as shown in Fig. 2wh,ere it projects downward into the pocket.. Y

The pocket is made Wider than thejthickness of the wedge, to afford clearance at its opposite sides for the fluid .to pass into the adjacent `ends of thechannels, as is indicated by the arrows in Fig. 2 at opposite sides ofthe partition. The wedge-shape of the partition facilitatesthe passage of the fluid from theinlet to the'whole length of the pocket.

The partition for the outlet-pocket d has a parallel portion Z extended about one-half its lengthA which is tted to the notches i next the center 'of the plate, and the par-L tition is wholly tapered therefrom in a thin wedge Z: to the' outer end` of the pocket, which coincides with 4the outlet-aperture f.

Where this partition extends downward into. the pocket d, it is formed with a wid- 'enedbutt Z2 whichjlls the pocket adjacent to the inner or central channels e, and is tapered to thesides ofthe body-portion Z.

.It thus restricts `the fiow from the inner channels which is only effected in the narrow wedge-shaped space a at the sides of such' butt.

'The tendency 'of an elastic fluid like steam, when a'dm'itted to these concentric channels, would be to take the shortest path through the channels next the center of the plate, so that the center of the plate would be heated much more quickly and effectively than the outer portion. v

. The restriction of the outlets from these central channelsto the pocket d prevents a rapid flow of fluid through these inner channels and causes' an equal distribution .of the Huid tothe outer channels, thus securing a uniform temperature of the whole plate.

It is obvious that if the notches z' of the Y faces.

ribs e 'were disposed over the pockets" c, d, the uid when introduced to the inlet-pocket .cfwould :pass from both edges of the same' pockets c, (Z. Such projecting parts would,v

however, interfere with the facing-oil? of the ribbed surface of `vthe top-seat, which is necessary to give it an equable bearing upon the top lof the base a, and the use of loose partitions thus vfacilitates the proper finishing of the parts.

The formation of the top-seat separa-te:

from the base is obviously necessary to introduce the partitions to the pockets', and the marginal rlng g serves to center the top-seat upon the base and'alsoto receivev an annular clamp g which is provided upon the ring g to press the margin of the topseat closely upon the base. v

A flange h3 is formed upon of the top-seat, and the annular' clamp is constructed to overlap the flange k3A and is enabled to form a steam-tight joint between the flange apd the base by pressing upon a collar of yleldingl packing between the flange and the under surface of the clamp. The clamp is securedto the ring g by numerous screws g2 which are adapted to resist the pressure of the steam employed in such plates when used -for heating purposes; and these screws are arranged to compress the packing j and spread the same to form a tight joint with the adjacent sur- The top-seat is also preferably secured to. the base by a center stud m extended through a hole a in the base and secured beneath the same by a nut m.

The inlet or outlet to either of the pockets.

may obviously be extended through the edge of the plate, as shown at f in Fig. 1, or to the bottom of the plate, as shown at f.

The disk mold p is shown in Fig. -1 clamped detachably upon the upper surface of the top-seat by gibs g and screws T, which illustrates the securing of such mold-parts to the plate to be heated and cooled thereby in a press.

the' margin Figs. 5 and 6 show bosses h upon the iny ner side of the top-portion 7L to receive the holes'l k2 for the screws 1 of the-gibs g., thus securlng lightness inthis partof the structure.

From the above construction it will be seen that my invention provides means, in

Laconic uted positively into opposite halves of the plate so as to heat them simultaneously and equally; and also prevents steam from passingA through shorter channels more freely than through the longer channels.

The edect ci the whole construction is to secure rapidity of uniform heating over the entire surface of the plate, and facilitating also the alternate heating and cooling of the plate when required. Y

Having thus .set forth the nature of the invention what is claimed herein is:

l. ln -a plate for heating or cooling, the combination, with a, base having a radial pocket in its upper side disposed as set forth, of a top-seat united to the base and having ribs forming channels encircling the center of said' seat and intersected radially by apartition extended downward into the 1 ocket in the base, with clearance in the poc et, at oppite sides of the partition, connecting with theA said channels, an inlet supplying a heating or cooling duid to the said pocket at one edge ot the base, and an outlet from the opposite side of the base, whereby fluid is distributed laterally in the said channels in both directions from the said pocket to reach the said outlet.

2. ln a plate lor heating or cooling, the combination, with a base having a dat top with opposite radial pockets therein, of a top-seat united to the base and provided next the base with a plurality-of circular channels, an inlet and outlet in the base connected respectively to 'the outer ends of the said pockets, the duid in the inlet-pocket being thus admitted from both sides oi the inletpocket into the channels between the ribs, to reach the outlet connected with the opposite Outletpochet, l Y

3. ln a plate :lor heating or cooling, the combination, with a base having opposite radial pockets in its upper side, of a top-seat united to the base `and provided nent the base vwith a plurality or" circular channels with opposite radial par Jitions intersecting the said channels and projected downward into the pockets for the purpose set forth.

d. ln a plate tor heating or cooling, the combination, with a base having opposite radial pockets in its upper side, of a top-seat united to the base and having a plurality oi" concentric vribs forming channels curving about the center ot said seat and intersected radially by opposite partitions extended downward into the said pockets, an inlet supplying a heating or coolin duid to the outer end of one oi the said poc ets, and an outlet from the outer end of the opposite pocket.

5. ln a plate for heating or cooling, the combination, with a base having a flat top with opposite radial vpockets therein and an inlet and outlet in the base connected respectively to the outer ends of the said pockets, of a topseat united to the hase and having a plurality of concentric ribs and channels supported upon the top of the base, and partitlcns radially intersecting said ribs and extended downward into the said pockets, with clearance in the pockets, at opposite sides of the partitions connecting with the channels between the said ribs.
