4793. Haddan, R., [Pfaff, R.]. Feb. 26. Bottling.-In a rotary-table bottling-machine of the type in which the bottle-holders are lifted by fluid under pressure, all the operations for charging with pressure gas and filling the bottles, and for the supply and return of pressure fluid for lifting the bottles to the filling- heads, are controlled by a single central cock. In the form shown, the plug 2 of the central cock is stationary and the shell 3 revolves with the filling-heads, but this arrangement may be reversed. The supply vessel 4 is carried by the plug, suitable passages being provided for the supply of pressure gas and liquid to the filling- heads 6 and the return of snifted gas to the reservoir. In one form of the invention, compressed air for lifting each bottle-holder 29 is supplied by an air-pump, not shown, through channels 9, 11, 8 in the plug 2, one of the channels 12 in the shell, and a pipe 13, shown at the left-hand side of Fig. 1, to the cylinder 31. At the end of the filling-operation, rotation of the machine enables the air to flow through the right-hand pipe 13, channels 12, 14, 15, 16, and a pipe 34, into the atmosphere, allowing the bottle-holder to descend. The pressure of the compressed air is sufficient to overcome the bottling counter-pressure as well as the weight of the parts. In a modification of the invention, Fig. 6, water under pressure is used for pressing the bottles against the filling-heads. The water is forced through a pipe 41 by a pressure and suction pump 40, and then through passages in the plug and shell and.a pipe 13 to the cylinder 31. Instead of exhausting to the atmosphere, the liquid flows back to the pump through the passages 14, 15, 16, 17, a pipe 34, a channel 44 in the standard, and a pipe 47.
