Abstract: 14,041. Saulson, P. J. Oct. 29, 1914, [Convention date]. Fixed-chamber apparatus for aerated liquids with automatic control of flow; discharge by separate fluid; controlling passage of air and gases.-In a machine for filling bottles, siphons, &c. with beer or other liquid under pressure and out of contact with atmospheric air, in which the liquid is forced from a measuring- vessel to the bottle &c. under gas pressure admitted to the vessel subsequent to the admission of the liquid, automatically operated valves are provided to ensure a flow of gas into the vessel as soon as the vessel has been cut off from the source of liquid supply. The receptacle A, Figs. 1 and 5, to be filled rests upon a support b with its discharge nozzle a<5> in the terminal c<x> of the filling-pipe c''. Gas from a cylinder C<1> forces the beer &c. from a barrel C to a foam-separating and equalizing chamber c<5>, whence it passes by a pipe c<6>, valve D, T-piece c', and pipe c' to a measuring-vessel E. The measured quantity of liquid passes under gas pressure from the vessel E by the pipe c<8>, T-piece c<7>, and valve D<1> to the filling-pipe c<9>. Gas is supplied to the vessel E by a pipe c<11>, valve F<1>, pipe c<12>, and a needle controlling-valve G; and the gas displaced by the incoming liquid is led through a pipe c<13>, valve F, and pipe c<14> to the filling-terminal c<x>. The liquid valves D, D' and the gas valves F, F<1> are of similar construction. The valve D, Fig. 7, comprises a block d with a central bore d<1> and a passage d<3> terminating in an annular groove d<4> surrounding the seat d<2> of a spring-pressed diaphragm d<5>. The pipes c<6>, c' communicate with the passages d<1>, d<3>, respectively. The valves D, D<1>, F, F<1> are controlled by a float e<4> in the vessel E, the stem e<5> of which is connected to a lever e<7>, which is connected by a link e<10> to a lever e<11> pivoted at e<12>. The lever e<11> underlies a transverse pin e<13> of an arm e<14> on a shaft H, which is pivotally supported by a double lever h carrying at its forward end a cross-bar h<1>, by which the lever is pressed down, either by the operator or by contact with the nozzle a<5> of the siphon when this latter is placed on the support b. When the parts are in the filling position, a hook h<5> on the shaft H engages an arm i<1> of a shaft i<2> which carries an arm i<3> connected to a link i<4> pivoted to a forked lever i<5> engaging the cross-head d<8> of the plunger d<7> of the valve D. A link i<6> connects the arm i<3> to a forked lever i<7> which operates the valve D'. The valve F<1> is operated by a forked lever connected by a link to an arm on the shaft i<2>, and the valve F by a forked lever connected by a link to the same arm. A third arm i<31> on the shaft i<2> is connected to the spring-pressed plunger of a. dash-pot K. When the measured quantity of liquid is contained in the vessel E, the float e<4> is in its highest position and disengages the hook h<5> from the arm i<1>, whereupon the dash-pot K rotates the shaft i<2>, thus closing the valves D, F and opening the valves D<1>, F<1>. On removing the siphon, a weighted arm h<4> moves the frame h upwards and engages the hook h<5> with the arm i<1>; and when the forward end of the frame is depressed, the valves D, F are opened and the valves D<1>, F<1> closed. A valve e<2> carried by a float e<3> closes the outlet at the bottom of the vessel E when the vessel is empty. Figs. 9 and 10 show a modification in which the two liquid valves D, D<1> are replaced by a single rotary valve D<x>, and the two gas valves F, F<1> by a single rotary valve F<x>. The valves D<x>, F<x> are mounted on a shaft i<2x> having an arm i<8x>, Fig. 18, connected to the dash-pot K and an arm i<1x> for engagement with the latch h<5>, which is now pivoted in fixed bearings h<5x> and connected directly to the arm e<14x>. The valve D<x> comprises a fixed central body d<1x> loose on the shaft i<2x> and provided with chambered ends d<2x>, d<3x> on which are screwed caps d<4x>, d<5x>. The pipe c<8> and chamber d<3x> are always in communication by a passage d<5x>; the chamber d<2x> and pipe c<6> are connected by a passage d<7x>, the chamber d<3x> and pipe c‹ by a passage d<8x>, and the two chambers d<2x>, d<3x> by a passage d<9x>. Two valve-disks d<10x> keyed to the shaft i<2x> and pressed against the opposite faces of the body d<1x> are provided with ports d<12x>. When the parts are in the filling position, these ports register with the passage d<9x> and liquid flows from chamber d<2x> to chamber d<3x> and thence by the pipe c<8> to the vessel E. When the hook h<5> is disengaged and the shaft i<2x> is rotated by the dash-pot K, the port d<12x> of one disk registers with the passage d<8x> and the vessel E communicates with the pipe c‹. The gas valve F<x> is similar inconstruction to the liquid valve D<x>. Fig. 12 shows a machine provided with means for adding syruporextract, the rotary liquid valve D<x> being constructed as shown in Fig. 9, and the rotary gas valve F<1x> as shown in Figs. 13 and 14. The syrup passes by a pipe m to a measuring-vessel M, which preferably consists of a central glass portion m<1> with metal end-caps m<2>, m<3>. A vent-valve m<7> is operated by a float m<6> adjustably suspended by a screwed rod carried by a lever pivoted in the upper cap m<2>. The syrup is admitted to and discharged from the vessel M through a. bottom connexion m<8> and valve N, which may be of similar construction to the valve D<x>, Fig. 9. In one position, syrup flows into the vessel M from the pipe m and in another position the syrup flows from the vessel M through the pipe n<1> to the siphon, in advance of the liquid from the vessel E. Passages f<6x>, f<7x> in the stationary part f<1x> of the valve connect the chamber f<3x> with the gassupply pipes c<12>, c<11>. A passage f<8x> connects the chamber f<2x> and the pipe m<9> leading to the top of the vessel M, and a passage f<9x> connects the chamber f<2x> and the pipe c<13> so that gas displaced in the vessel E may be delivered to the syrup vessel M. The valve-disks f<10x> have ports f<12x> registering alternately with the passages f<9x>, f<7x>. When the predetermined quantity of liquid has entered the vessel E, the latch h<5> is disengaged and the shaft i<2x> rotated by the dash-pot K so that the valve D<x> places the vessel E in communication with the pipe c<9> while the valve F<1x> places the vessel E in communication with the pipe c<11> and closes the connexion between the pipes c<13>, m<9>, thereby cutting off the gas from the vessel M and allowing the vent-valve m<7> to open; the valve N cuts off communication between the vessel M and the fining-terminal e<x>, and opens communication between the syrup pipe m and the vessel M until the flow is cut off by the float m<6> closing the valve m<7>.
