able fromlthe press-without dismantling.
It has heretofore. been necessary to dis"- mantle-pot pressesin order to remove the I V begotten lntoi such position as to be tipped platens, as when platens are brokenfor required to be repaired.- Such'apress is shown,
in my prior Patent No". 1,478,699,0f Dec; 25,
1923. Presses} of this typehaving platens;
mounted on steps', as, forexampleylthe steps 24 shown in my said prior patent-,require all the'platensto be difierent'in construction in that the consecutive pl'a'tens are constructed with lugs for supporting 'them on theirstep supports; which lugs are of increasingly greater length from the bottom platenato the top platenof the'press, softhat when-the platens are dropped down afte'r'the pressing operation-is performed, each will be stopped at its-own normal location in the press. This has involved'the making of as manykinds of platens for each press as there are platens in the press: Platens so differently conp structed for the: diiferent locations in the press are not 'interch'angeableandin case of'a replacement, for example, of a broken platen, only a platen of the same construe-n tion and adapted for the particular location in'the press can be made' ilse of. Alfu'rther and very considerable disadvantage in such prior presses is that removal of'a platen can be accomplished only'by dismantling the press, includingthe' removal of the supportmg racks, and, in presses of certain makes, requiring the removal of the "pressh'eadand other major structuralparts of the press, all of which-must be reassembled and in'some cases the" press'practicallyrebuilt after the 1 platen is replaced.
The-principal object of the presentinvention is'the doing away with thenecessity for "dismantling of the structuralfpartsofthe press, such as racks,c0lun'1ns, presshead and the like,-in order to permit-removal orre placement of one "or more of the press platens. Another objectof the invention -,'consists in so constructing the platens as to a .c m a citizen of theUnitedStat'es, and a resident of East Orange, Essex County, "and State of New Jersey, have-invented anew andusefulflj Improvement in PlatensiforfPot Presses, of

VlSlOl'lbf meanswhereby lthe'stop lugs which ar' 'prefe'rablyj screwed in the platens "may be screwed out whilethe platen is in the press, Whichin turn permits the rcspective platens' to be-fdropped'down from their.re-' V spective steps'kwithout removal of the supporting racks, and whereby the. platens can up and withdrawn or, r f lO 7 between.
the column's'and racks. ofythe pressl'without f disturbing or "dismantling eithe'r the columns" 1 orracks. 1 f I p In the accompanyingdrawings,"Ifhave i shown 'suflicient' portions of the pot press to" '75; illustrate the application to such presses of thepresent invention and in said drawings"v Figll is apartial side view of a pot press,
such as shown in greater detail in Fig.- 1 of. my said prior patent, with parts broken away"fordisclosing'the interiorconstruction and with the runway members j or," platen slidesremoved'fromthe platens. Fig.2,isa
elf its step and one offits screw stop lugs looking in the, direction of the" arrows. Fig. 3is a horizontalsectional vi'ewflon the,
view 1 taken approximately along the line 4-4, Fig, 3,}showing' the lowermost of three "line 3+3,.Fig;l'1 fi Fig, 4 is a fragmentary I platens in-normalposition, the uppermost thereof raised and the intermediate platen ,9 Tlowereddown on one side and raised on the other side to'permit withdrawal of'the last named ,platen between the columns and Fig. 51lS a.
In said'drawings, the combined press'base and-"cylinder 10 and the presshead' 12 are" connected by the 0011111111514. The racks'l6 in which the press pots (not shown) slide in and outaresecured to the base-:andhead, preferably two on each side of thepress. f
These r'acks 16 are provided with the steps 18 which extend inwardly toward one another by uniformlyincreasingly greater dis tancesfrom the top to the hottom of the press in order that each platen may be stopped upon being dropped down after pressing by its respective'stop. The construction thus far described is as shown in my said prior patent.
A novel feature ofth e racks 16 of the ,niade alike and interchangeable, whereby they are adapted to be finish machined all alike in a gang or staclrand manufacture'is facilitated. Platens 22 are provided with bosses 23 at their corners. Said bosses have each a screw threaded hole 24 formed therein forfthe reception of the screw stop lugs 26.
Thecolumns 12 serve as guides for the up I and down movement of platens22 and the bored corners of platens 22 WlllCh run on the guide columns 12 are bored eccentrically as indicated at 40, Fig. 3, so as to make practically close contact with the columns'in the short inter-column direction and to have a moderately substantial clearance away from the columns on the line of the rela tively long inter-column direction. (See Fig. l.) This clearance is suflicient to establish such relation between the platens and columns that when the platens are otherwise free to tip they can be tipped in the direction of the longer inter-column dimension without making contact with and binding between the columns. trioity and capacity for tippability of the platens does not interfere with their being accurately guided by the columns when so tipped. One of the platens 22 isshown in Fig. 4 after having been tipped free from the columns in this manner.
In-order to remove the platen after the runways or platen slides (not shown) are removed from the platen and one or more pots taken out for working convenience, the
This eccenplaten to be removed is made accessible by raising the platen or platens located thereabove, whereupon the particular platen to be removed is raised somewhat as shown in Fig. 2 to bring the. screw stop lug 26 thereof opposite the recess 20 the rack 16. The screw stop, lugs can now be screwed out as indicated in the case of the right hand lug in the middle ,platen shown in Fig. 2. It
is usually sutlicient to unscrew two of the lugs on one of the ends of the platen, preferablythose of theend itis desiredito-ibe dropped or tippeddo'wn: W'hen'this :is done i the platen can be dropped down at'this end past its step and "raisedat the otherend" and made to assume substantially theposi tion shown in Fig. 4:. (It will be 'notedthat the pot runways42 in'the racks-16- are cleared by the platen. See"Fig.-3.) With the platen in tipped position as indicated in: Fig. isame can be drawn out'between the racks 16 while in such tippedposition, without disturbing orv dismantling either the racks or columns- This operation isreversedin case of insertionof: the platen.
I claim: V
