this cylinder is the ixed obturfi'ting plete 5 which. is common to all three cylinders while :there the piston (i o' si suitable l'iydrnulicpreliniiiuufy pressing device 7 is located;

when the cylinder has heen charged Ythis I piston descends and produces a cylindrical preliininurily pressed Vbut also provided with u cavity for the reception of the ether. i

:in order to prevent the nuiss from escaping upward u cover tney he provided which is provided with u central aperture for the p statige of the piston G. After this preinn y pressingr operation the' cylinder' 2 h itf charge is mused to occupy the positii 1 il' loy ifevolrirnigF it above the plate 5; th s is the position which the cylinder 3 is rcprNI rita-d :is occui'iying' iii-lijn". l oi' the draining. The revolution can he facilitated by suppinfting the lmll hearing' 8 of the body curryine; the cjiflinders Q, 3 and 4. on elastic materiel such as leather or the like which` the compression pressure ceases, slightly litts the cylinders from the plate 5` lo. the position ilv the cylinder is located :diode Ki, depression l() in the tuhle plete which contains u mixing' arm ll (Figs. l und secured to u screw spindle 12. At its upper purt the cylinder is closed by u. cover l-S which is preferably also hydrulicully applied und which provided -with a pussage lll` for the admission of the ether und ii I issepe lf3 VFor the discharge of the nir during; the charging. lt is preferable to provide for the obturation of both passages hy upon ai vulve rod und yicldubly pressed iu its scf-ut hy :i coiled spring :it the upper end ot 'the vulve rod. rlhe vulve can he depressed hy any desired Ineens such :is thev com und lever illustrated in Fig. l. The ether mimitted fills the previously 'formed ce i'ity und thus from the cou'iuiencement cornes large proportion of the 100 into contact 'with n amiss:l thereby largely facilitating the mixing'. The spindle l2 of the mixingr erm is driven in any convenient manner for eX- ;irnule by means oit belts 17, one running drum 19 which is in mesh with yu geur wheel 110 u single cone-shuped vulve 16, mounted it and 'the other crossed und runningT 105 ment tion Hl. ln order to obtain a uniform mixture and simultaneously an even division of thc mass provision is made enabling the mixing arin in its two end positions to carry out several rotations without advancing. Thesquare-threaded nut Q1, by 'which the mixing` spindle 12 is moved, is rotatably mounted ou ball-bearings: during,y the upward and downward movement of the mixing arm this nut is held Jfast by the pawl Q2 under inwardly directed spring pressure, which pawl re against the nose 24 ot' the threaded nut. lo, pon reaching the end of vthe upper or lower stroke a' cone friction wheel 25, by pressingr on a roller-2G of the pawl 22. diseng'ajes the latter. The nut is thus released. which. due to the thread friction which is always greater than the friction in the ball bearings, rotates with the mixing spindle 12. and hence the mixing' arm carries out a purely rotary movement. security the cone friction wheels 25 are each provided with a rigid stop Q3, which forcibly rotates the nut 2l after release ot the detent at the nose Q4. The movement ot the spindle 1Q advantageously reversed by some suitable means actin;i automatically upon the completion of a given number of revolutions. Then the mixingr is completed `the cylinder containing the mass is further rotated into the position lll it' desired beneath a suitable cover which may be fixed and extend from U to Hl. l'n the position lll it is located above a sieve-like die 28 and beneath a hydraulic press piston 29 which upon its descent toi-ces` the mass through'the die in the usual manner except t'or a portion which remains above the matrix in the form ot cake in which is retained any foreign bodies which it may contain. The material forced through the die reaches a suitable table 30 or convcyer mechanism in a form corresponding to the perforations in the die. Preferably the die tor the pressingr operation is rigidly connected with the cylinder and after the pressing it is re.

moved for cleaning purposes.

Naturally 'the position ot' the cylinder should be selected in such a inanncrthat in all three cylinders` the three operations proceed simultaneously, that is to say, While the mass is beingr charged and preliminarily Liedes@ ether i-1y ad' fl while ni .z

pressed in cylinder P and mixed in cylinder the mass is forced out.

ln addition to its employment 'tor die inanutacture of smokeless powder the machine described can also be utilized i'or exannile by adapting the construction to the special conditions tor the manui'facture of other products in which :i mass is to be mir-ed with a liquid and the paste thus l'ormcd brought into itslliual form bv pre. ip; and possiblj.'v subsequent disinte ral-ion.
