J. BEYRE ON THE MANUFACTURE OF SPARKLING WINES. 337 



the stand d d on which the bottle is placed. On releasing the 

 treadle, the springs r r press the bottle against a circular piece of 

 India-rubber in the middle of c c. Take now the p^ateaw c c, move 

 it forward so as to turn it over the body K of the stopcock, which 

 forms part of the upper plate c c ; thus the frame c c, c' c' is 

 brought in the position indicated by the punctuated lines, and 

 the bottle is in B. After this semicircular motion the gas in 

 the interior of the bottle is balanced by that in the interior of the 

 ball S. 



This is plain if we examine Figs. 47 and 48, in which the stop- 

 cock 11 is represented in detail (one fourth size in Fij. 47, one 

 half size in Fig. 48, with the same letters in both figures). The 

 body E is represented by the letters A B D E. It consists of a 

 piece with a plate C F {Fig. 47), and the picee of the cylinder d d', 

 furnished with a thread of a screw, fastened by a vice of bronze 

 h h\ the use of which is to keep the circular piece of India-rubber 

 in its place, against which the head of the bottle V is pressed. 

 The lower metallic mass of C D E F contains two round grooves ; 

 to the vertical one r r' is screwed a silver pij^e r", at the lower 

 extremity of which a flexible pipe r' r" is fastened, long enough 

 to reach the bottom of the bottle. The other groove z v^ thrice as 

 broad, is intersected by the first at d d' ; it inclines about 40° to 

 the left, and extends to the key at v. 



This key of the cock is immovable ; it consists of a long fur- 

 row T T' T'', and its conical part has four openings from D to E. 

 The first one, ?", terminates the furrow m m\ which is to receive 

 the carbonic gas ; the second, G, opens the furrow G II, through 

 which the wine runs into the ball S. 



These two openings lie in the vertical plane T z T' ; the two 

 other ones are 45° from this place and the centre of the cock m 

 {FigA9). 



The one, u, lets the gas escape which entered by m m' ; the 

 other, ?/, is the entrance of another branch arm 3/ o, of a second 

 furrow o 0, with an opening by the same key, 8 or 4 millimeters 

 back of VI m'. This furrow terminates in a second branch arm 

 0' y' (a little to the right of point T), and the opening y corre- 

 sponds with the furrow y' N, intersected by the stopcock N. The 

 furrow m in' shov/s a stopcock O R between T' T". This cock 

 has three passages ; the furrow T" connects with the furrow X", 

 which lets in the gas from the regulator or condenser. The ver- 

 tical furrow ^"' joins the furrow X', which connects with the 

 ball S. 



Now the treadle is pressed down, and the bottle, after the dregs 

 have been removed, is inserted in the frame. The grooves r r' 

 and V z are closed by the key of the cock ; the wine is in a vessel 

 which is hermetically closed. The frame is taken off, in order to 

 turn the bottle upside down, so as to give it the position v' z'. 

 While this is going on the body of the cock first brings the open-
