` subject of 'King of Italy, residingy at Florence, Toscana, Italy, have invented new and usetul/ Improvements in` Compressed-Air ,ll/'atei' Elevators, of which the followingis aV spe'ciicz'ition.` y

The invention forming.;` thel subject-matter of ,the present application isfan improvethe corresponding applicationy thereof. In

the same`,'Fig. l is vaside elevation off the apparatus as appliedy forWorkingV purposes-fY IFig.l 2 is a longitudinal 'section 'ofthe chest for 4 they distribution of the rcompressed i air vFiga 3 is a transverse,sectional view ,taken approximatelyv on the line, 3-3 of Fig.r 1,'

'looking in thevdirection of ,the arrows, and drawn to a,y very lmuch larger scale than Flg.`

., ll, and Fig.,4is la rdetail of` the motive gear attached to the driving shaft. j

Fig, lshowsthe complete system in wor-lc` ing;l order, with ythefsuction pipes -w-b-f in communication with| the two receptacles Q -,de ,immersedin the liquid to be raised.` The twol pipes connect lthe 'twoI receptacles #c2-d with the dis-k I tributinpvchest-wl The two receptacles are furnished at their lowerrpartwithfvalves -cl-'rll-g' this allows the compressor `to draw in theair froml one o'l'the two recepta- 'cles and' to compress itin the other, in such manner that, of the two receptacles, the one sustainingr the pressure will'tendto discharge its water, which will be,l driven Vinto the outlet pipe through one, of the two valves -c2-d2-; thus the same receptacle will be emptied of water but illedlwith compressed air. As soon as the receptacle has delivered its water,-the passages in the air valve chest are reversed, so that, whereas, at first, {suction was effected from one receptacle and compression in the other, the converse will now occur, i. e. the compressed` air will be drawn in from the receptacle already yemptied of its water in order that it maybe sent into the other receptacle, so that its liq^ uid may, in its turn, be discharged and, in the mean time, the first receptacle may be permitted to be filled with water.

' The above mentioned reversion @of the`v chest passages isbrought about in the `following manner;y to the driving;y shaft "-9- '(Figf-` land 4i) of the compressor is fitted'V a`-worni 72 gearing with va* worm`-wheel y kwhich convey the/motion of the's'ha'it rgto the aXle 7cy I Said aigle -]cv 'entersk the vboxpea* fitted to ,the chest `-e-' and by meansof the endless screw `geariiipx--fmimparts the motion t0. the ytoothed wheel '-awhich, in its 'turn actson the cam esi -0-, which, by its rotation, imparts motion'to a lever ep# ofthe first class. This leve'r *p-fispivoted vto a 'smallfdouble piston glwhose pistonsf-r-s'- are equal4A in diameter andthe pressure on` whichr equilibrates said rod.r `The'Oscillationl ofthe lever-ip' effects a' rapid reciprocation of the pistor'i'rod 7 atk stated intervals, which, by suitably proportio'ning the `gearing", maybe.,

varied to suitthecharacteristic features of `the working of the'compressor'.` This isone system for Obtaining motionlofthisjdescription, but other means may fbe'e'mployed to so producethe same result 'and at the same,timem render it possible toloc'ate ,theV chest aty any distance from the compressor."

Q Assuming, for instance, thatpthejaxis of the ,helical screw l21`L,which Imovesfthe heli small electric motor, whose speed iswell de?y fined, instead of 'receiving itsimotion from the y'main shaft: of the'compressor'lby means `of the wormgearingf fue', manifestly the,"

eect in respect fotv the"'functioningr [of the" system is identical with that in thefirst instance ,Lit is also plain that the speed of rotationjoil the cam 0, besides being variedfby the regulationoit lthe speed ofthe smallino-v tor, may alsov be varied by changing'` the4 number of `Jteeth Lof the helicoidal lwheel n orl the number of the threads of 'the helical screw m, or also bythe transmission of the motion ofthe cam 0 by several couples ofy screws and helicoidal wheels or of gearings, which gradually bring about the slackening of the movement until a veryslow motion is imparted to the cam 0.

The same may be' lsaid should it be ldecoidal wheel n and, therefore, ,thecamclike-n -w1se, receives its movement vvdirectlyfrom a sired to employ a small compressed air mo? tor, viz: ka small aeromotor (instead of a small electric motor), which by also yacting y in the case ofthev small electric motor and tion alluded to, the small double piston g1-v instead of being operatedfrom the compressor assumesat given intervals of time one of the two rwell defined positions in order Ato alternately close either the couple of orificesk-s-t-uof the chest -ee- (and, in ,this case, into thepipe -awhich is at- I tached to the flange of the chamber .-'y-

is admitted the ,compressed air from the compressorpand through the pipe -bwhichvis attached to the flange of the chamber iii is effected the suction of the compressor) or 1 the coupleof orifices fw-- of the same chest ef- (and 1in this case through the pipe attachedyto the flange of the chamber -fl/-` is effected the suction ofthe compressor and into the pipe attached toy thefiange of the chamber -iisadmittedthe compressed air from the lcompressor itself.)

f In l,order to allow of the compressed air `which has beenaccumulating in one ofthe klower receptacles 0, d, passing as `"quickly as possible into the other receptacle to expel y 4therefromthewater which lias'been introduced into it meanwhile, r the length of the pistons i,fs of the small double pistonisless thanthewidth ofthe chamber -i/'between the kapertures tand androffthe chamber e 'bef ,tween the aperturesem/w, as shown in Fig.

2, the' result thereby obtained being that during thereversing-Qf the chest-a part ofl the compressed air of one of the receptacles passes rapidly and directlyfroni the chambervv into thefcharnber Ii/l., o r vice-versa, without acting on the compressor piston, 'which vifsof great advantage in respect of the use-y ful effect ofthe System and in ensuring the proper function-ing of the compressor. Moreover, the variation of the runfof` the fcurve'of the carrro it is possible, duringthe reversingmotion ofthesmall double piston to kvaryfthe time during which the direct discharge off-the compressed air between the two ,chambersA y and fv' takes place.l

The parts faand elform together a stuffing boit `for guiding the piston -rod g' at one end thereof while the parts 2 and 3 form together another stuiiing box for guiding said rod at lits opposite end. In order that the pistons 7' and s. may be made perfectly airtight, by the closure of two of the orifices z5-u and --fw-, the bores of which are all of the same diameter, all that is necessary, in cases where the degree of pressureis not very high, is that there shall be the least possible difference between the diameter of the oriices and -nx-fw-V and that of the'pistons -frand ,-sa difference of .Ol of atmillimeter being sufficient. For very high` degrees of pressure, the rairtight litting may be rendered more perfect by fitting/che pistons The flanges 'and 5 serve respectively for the drawing in and expulsion of air from the c.Ompressorn,y

The auxiliary valve allows ythe compressors suction also being taken fromr A liquid raising apparatus, comprising combination, an air compressor, a pair of receptacles having valve-controlled inlets for admission yof the liquid to be raised, a distributing chest between the compressor and said receptacles kfor alternately causing the air to be exhausted ,from .one receptacle and compressed in thel other and vice versa, said chest having a chamber in communication with @achtet-the receptacles a double piston axially slidablek in said chest for opening one `of'said chambers to lcompression"and, the

other to exhaustion during a part ofthe operation of the compressor, and reversing such action during the remainder of said operation, and a cam operated by the compressor for reciprocating said double" piston. .i

In testimony whereof I have r signed my naine to this specification.
