v Vthatwhilelsuch pressis'shown as avertically ',acting:press,-it'will :be obvious, fromttlcre en-.v Vsuingdescription, that the .Valver'neehanism- `is applicable to other styles of'yertical presses, and lalso toother than, ,-uertically acting presses, Without'ldepartingrfrom.the essential.v spirit ofmy invention.` I joxvrever, as' Shown., V`12des'gna'tes aninlet or -supply pipeleading from any4 suitable source of wateresupply, under head or. pressure,i and extendin'ghori'- zontally across one sideof themachine. At one end, this inlet-pipe12isconnectedto an inlet-valve casing 13.v containing.'a'fyertically movable inlet'valve 14 and? communicatmg,

by a :lateral outlet, located. nears/the upper endiof the Valve-casing, ,with ancinlet-chander 1 fand communicating withi thepstonchamber thereof. 1 At-a'suitablefpoint, this 'inlet-pipe.' 12 is also connected to a second i inlet-.valve casing 16 which issimilar in all 8 0 nel v15t'ormed in the' lower part of the cylin#v respects to theinletfvalve casing 13an`d which presses :provided Awith-wan automatic 'valve-r communicates in precisely'similar.manner j with thepiston-'chamber ofthe cylinder 2; fthe inlet-valve casing 16 containing also anfinlet -jfvalve (not'shown) which is precisely similar "to the inlet-valve 14 justdescribed.- The arrangement is such that, when the inlet-valves 14 are-alternately raised, .water is allowed 'to f iow through .the valve-casingsl and 16 and -the pistons or plungers 3' and 5 areeaused' to alternately rise, while when theinlet-valves j14 are depressed, water is shut Yolf'Y fromtheY valve-casings and eylinders,.and the pistons IOO . ,55.f` plungers'iand.with their..

. a suitablepoint, this main outlet-pipe com` nected one end of a branch outlet-pipe 18. At its opposite end,the branch outlet-pipe is connected with the casing 19 of avertically inovable outlet-gate valve, of any usual or pre1 ferred type; this casing 19 beinglocated at the opposite side of the cylinder 1 from `that to which the inlet-valve casing13 is adjacent, and being also connected to a main outletpipe 2O shown as extending horizontally at the opposite side of the machine from that to which the main inlet-pipe12 isadjacent. At

municates also with a second outlet-gatevalve casing 21 whichcasing communicates with the `lower part of the piston-chamber of the cylinder 2 inprecisely the saine manner as the outlet-gate valve casing 19 communicates with the piston-chamber of the cylinder 1; the outlet-valve casing 21 being located at the opposite sideot the cylinder 2 from the inlet-valve casing 16, and containing a vertically movable gate similar to the gate in the casing 19. The arrangement is such that, by

alternately raising the outlet-valve gates inl the gate-valve casings 19 and 21,the `water will be alternately discharged from the cylinders 1 and 2 and the plungei's 3 and 5 will be allowed to alternately descend. 22 designates a rock-arm which is secured midway of its length upon oneend of'a rockshaft 23; this shaft extending horizontally between the upper ends of the two cylinders 1 and 2 and the rock-arm 22 extending along that side of the machine to which the inletvalve casings 13 and 16 are adjacent. At one of its ends, the rock-arm 22 is connected, by a pendent link 24 to the upper end of the stem 25 of the inlet-valve 14, and at' its opposite end said rock-arm is connected by a pendent link -26 to the upper end of the stem 27 of the inlet-valve in the valve-casing 16.

Upon the opposite end of the rock-shaft23, from that which carriesthe rock-arm 22, is secured (midway of its length) a second rockarm 28 one end of which is connectedby a pendent link 29, to the upper end of the stein 30 of the outlet-gate in the valve-casing 19. The opposite end of the rock-arm 28 is connected, by a pendent link 31, to the stem 33 of the companion outlebgate in the valvecasing 21.

34 designatesa lever whichis pvoted midway of its length in a hanger 35 which is pendent from the under side of the cap orl head 7, and 36 designates a second lever which is pivoted midway of its length in a hanger 37 pendent from the under side of the cap or head 9; these levers 34 and 36 extending approximately transversely above the plungers 3 and 5 respectively.

To one end of the lever 34 is connected the upper end of apendentlink 38 the lower end of which is connected to the rockarm 22 near that end of said rock-arm to which the link 24 is connected. To the corresponding end of the companiondever 36 is connected the upper end of a pendent link 39 the lower end of which isconnected to the rock-arm 22 near that endof said rock-arm to` which the link 26 is connected. Totlie opposite end of the is connected, is connected the upper endofa pendent link 40 the lowerendof which is connected to the companion rock-arm 28 near that end oi said rock-arm to which the upper end of the link 29 is connected. To the op posite end of the lever 36, frointhat end to which the link 39 is connected, is connected the upper end of a pendent link 41 the lower end of which is `connected to the rock-arm 28 near that end to which the pendent link 3l is connected. l

' -To the lever. 34,at a` point `between its `hanger 35 and the end` to which the link 40 isconnected, is pivotallyconnccted the up- .i per end of a short. pendent"strikerfarm 42,`

while to the companion-lever 36, at a point between its hanger 37ifand the end to which' thelink 41 is connectedy is pivotally con-l nected the upper end ot asecond shortpend` ent striker-arm 43. These arms 42 and 43 "lever 34, from that end to which the link 38 are shown respectively as working loosely i through the outer ends of guideariiis44 and 45 which extend liorizontallyffrom tlietwo ini nerstandards8 and 10 ofthe machine, but

theseguide-arms may either be employed or i dispensed with as preferred.

The operation of the above, described valvethe link 24 is connected and depresses theinlet-valve 14 in the valve-casing 13 so as to close said valve, and thus shut otE the water from the piston 1. Simultaneously, the upward movement of thelever 34 and the consequent upward movement of the link 40 lifts and opens the outlet'- gate in the casing 19 and allows the water to `escape from the cylinder 1; the plunger 3 instantly descending.

` On the other hand, the depression of said end ot' the rock-arm 22 to which the link 24 is connected is accompanied by the ascent of the opposite end of said rock-arm and of the link 26 which is connected thereto. This ascent of the link 26 lifts and opens the inlet-valve in the valvecasiiigllG `and admitswater to the cylinder 2, and at the saine time, the ascent of this end ofthe rock-arm 22, acting through the link 39, tilts the companiondever 36 so as to depress that end of said lever to which the link 41 is connected. The depression of the link 41 lowers and closes the outlet-gate in the casing 2l and so prevents the escape of water from the cylinder 2;` the plunger 5 of said cylinder consequently rising as the pluri ger3 of cylinder l falls. Plunger 5, at thc completion of. its upward movement, strikes ioo` rio
