Application filed April 10, 1922. Serial N0. 551,344.

T all wlzom z't may c0n0e1m L' l3e it knownthat 13 CYRUS KEHR, a citizen 0f the Unitecl States, resicling at l Vashlhgton, in the District- 0i' Columbia, have inventecl a new and useful Improvement in Presses, of which the l?ollowing is a specificntion, rolerence being hacl to the 11000111- panying drawing.

This invention relaes partlcularly to p1esses containing a. series 01 group of superposecl horizontal plates o1 platons batween which sheet-form material is to be placecl f01 Pressing, the plates o1 platens being at cimes separatecl to permit the insortion of material between thor.n zm cl being afterwarcls forced towarcl ezwh other to engage ancl press the material.

The objeot of this invention is. to procluce a maohino emlooclying effective mechanism fol controlling anal moving the plates 017 platens.

In the accompanying chmvings,

Fig. 1 is-a frontelevation of a machine embodying my improvement, parts being 25 b1okon oway;

Fig. 2 is an elevation of one 013 Ehe encls of the same machine;

Fig. 3 is a plan of the same xnachine pnrts, being broken away;

Fig. 4: is ahorizontal section 011 Ehe line, 44, of Fig. l; k

F 5 is a horizontal section 011 the lino,

Referring to saicl dmwings, A, A ure lour upright corner posts OICOlU.II1I1S forming arts of the fmme 0f the machine. These columns aro of angle form, as shown in cross sectionih -Figs. l ancl A1; each encl of the machine, the upper ende of the cornezr postsore connectecl by a clmnnel bezun l loolcecl. to the corner posts; und at euch orul of the.machine, ehe corher posts a1e sinnllarly joinecl by a horizontal chzinnel beam, B bolted lzo the corner post ne2u the lowor encls 0'E he latter. At the front flil(l at the rearof: the machine, tho uppar oncl3 0'E the corner posts are joinecl by 21 horizontal angle beam, B ha ving a horizontal flange resting 011 Ehe upper encls ol the corner .posts while the other flange exencls clownward flatwise againt the outer faces of the corner posts. Saicl beams aie suitably bolte tl to the corner posts. At each slclo of the machino, near the lower encls of tho cornor posts a horizontal channel beam, B, joins sail corner posts, said beam. being boliecl so saicl posts. The memloers thus far clescribecl constlt-uto the fmme of the machine, excepting that the britlge pleces to be cleiscribed furthefon may also loe regarclecl as l1mne membors.

The plates or platens am horizontal und am 01 two kinds active :md idle. The active platens iue lirectly engagecl und raise l und lowerecl by lifting mechanism. The idlo platens am not engagecl by the lifting mechanlsm, bat are engagecl only loy the atctive platons.

C, C am the iclle platena These. alter- :mto in gosition With the acive platens D, D.

The 21ctlve platens a1e wicleonough to 1nake thelr front ancl rear clges mee the front ancl re:u flanges ol' the corner posls, A. Thus the platens are hold against for- W2ucl 01 backwarcl movoment. A bar, C extends across each ond of each platen, C, ancl is secured therotyo by bolts, C extencl ing through the bar into the platen. Tho oncl of each of saicl ba1s extends through an upright slot, A in 'the front anclrear flanges of ahe co1ner postS. Normally saicl bars rest in the lowo1 purt of the slots tho platen belng hold at rest in this 1112111118 Bach slot extencls abo-vothe bar, C fa1'- enough to allow he lifcing 0]? the platen through a short range.

'lhe bars, C Can 11011 move Sidewise in tho slotsl Hence saicl bars hold tho platens C, agains enclwise movemnt, whilo the ffont anal 1em; fianges of the corner posts, A, hold saicl plate:os ag ainst for-wrd or baclnvarcl movemenl.

Tho active platens, D, D am of the SBIDO width the iclle platens, C, C, am: the platens, D, D are long enough extencl against the encl fianges of the corner 'laosts, A, A. Thus tho active platens -are hold agalnst siclewiso movement anal uvainsfu endwise movemont. n oach encl o3': each platen, D, noar each corner pos't, is a horizontal wrist, D, which is rigid on the platen. Surroundmg eachsuch wr1st lS an antrfriction roller, D which is adaptecl to engage ehe fiange, F of a cam, F, which surrounds ancl is fixecl on the acljacent upright shaft, E. Bach of said shafts has its lower encl resting in a bearing, E whilo its upper encl extencls through a bearing, E Immediately above the bearing, E, eaeh shaift has an annular shoulcler or ring, E which rosts on the ajacent bearing, E On each ca1n, F, the flango, F is directecl upwarcl ancl is ooncenrio with tho shaft. Saicl fiange varies in heigl1t, so tl1ac cluring the rotat-ion oi' tl1e shaft anal the cam, the p'art oi' the fiange passing beneaz'ih the roller, D", Will vary in height. By this means, the roller, D ehe wrist, D und the platen are liftecl. Tno four cams which are opposite the sa1ne platen, D, aro set 011 their sl1afts to simultaneously present tl1e engaging parts of ino flanges in oho sarne horizontal plane, in orcler rhat the' platen may, during its movement, loe kept parallelto a horizontal plane.

The shafts, E, ancl ehe cazns, F, are t0 be rotatecl continuously or at intervals as may be clesired.

On the upper encl of nach of saicl shafta is fixecl a worm wheel, E*, Whi0h is engaged by a Worm, G, fixecl 011 a horizontal shaft, G resting in bearings, G seatecl 011 tho upper end beams, B of the frame of tl1e machine. Such a shaft is locatecl at each oncl of tl1e machine. Ab the miclcllo of eaoh 0f said shafts is a worm Wheel, G which is fixecl to saicl shaft ai1d is engagecl by a worm, H, 011 the cross shafc, H which rests in bearings, H for'mecl 011 ehe transverse horizontal bricl e pieoes H which hav, their encls resting on ancl boltecl to oho uppor front ancl rear horizontal bean1s, B? Between the bearings, H a pulley, I, surrouncls ancl is fixed tothe shaft, H. Power is tobe applied to said Pulley by a holt.

When saicl pulley is rotated, the shafts, H G, andE, are rotatecl. By the rotation 0f the sh'afts, E, t-he oams, F, are rotatecl. The rocation of tho carns C&USGS tl'1e liftin'g and lowering of the active platens, D. WVhen tha highest parts of the i'iangs, F of tho oa1ns pass uncler tl1o roll@1*s, D of a platen, D th at platn is liftecl liigln onougl1 to bear agaiiist the next upper icllo platen, C, and

Durin'g the continuation o1 tl1e rotation 0f tl1ose four' cams, the higher parts of the carns again come im ler tlie rollers anl lift tll@ni ancl the1r platen unt1l S211Cl platen again bears.

against and lifts the next upper platen. This action continues as long as these ca1ns are being rotated. V

The four cams of any platen may be set into their radial relation 011 the shafts, E, without reference to tl1e radial set-ting oi the eams whicli are associated Witli other platens. If so desirecl, all he cams on tlae four shafts may be Set in tl1e samo radial re lation so that all oho cams will lift all the platens, D,simultaneously. Bub that would. involve tho lifting of all the active platens ancl all but the lower 013 the idle platens at ehe sa1ne time, tl1us making an accumulation of load equaling the weight oi all the platens, D ancl all the platens, C, excopting the lowest ancl tl16 maserial ab the time between the platens, exce'pt the lowest. Tne loacl to be thns liftecl can bo recluce(l by distributing o1 clivicling the radial arrangement of the cams 011 the shafts E. Any such division Will divicl6 the loacl 150 bo liftecl. The clrawings ill'ustrate a complete division of the arra1igement of tl1e carns, the highez-t part 013 t-he flanges 0f the several groups 01 cams being turnecl progressively to (livicle active Cams are brought successively to the upper l1in1 oi": the1r range of movement. By

this means wo attain the minimin of loacl to loe liftecl als one time.

It will 'be unclerstood tlra.t tlie sheet-i'orm inaterial to be pressecl is to oe placed into the space between any two platens whenthose platens are separatecl from eacl1 othei. It Will also b unclerstood that the material 1I1ay be left between anytwo platens until those platens have been separatecl ancl brought into engagement as; often as needed for the treapment of saicl material.

If it is clesircl to have tl1e plates warmor hob during operation, they n1ay be made hollow or otherwise formed for oonrlucting steam 01 l1ot water through themi Tl1e drawings show ports, J,J, on the ez1cls of the platens for the connection of tuloing through which hot water or steam may be cleliverecl into an l exhaustecl from tl1e platens in the manner alreacly known in this art. 7

lt is to be noted that the cams anal the rolleirs are no ooupled n or otlierwise'permanently engageclto eaoh other,that the canis 2116 free from the rollers, D tl1at they en glage the rollers only by moving upwalrcl ancl ens, arid"ndeans i.or liftii1'g'tlie platens of one of said groups at d1ileizant times, substa;nt1ally as desor1'bed.
