2 Claims.

This application is a division of application Serial No. 617.709, filed September 21, 1945, which has become Patent No. 2,420,850, issued May 20, 194'?.

This invention relates to a dispensing apparatus particularly though not necessarily designed for use in connection with soda fountains from which a beverage from a mixture of liquids is dispensed. In this aspect of the invention, a principal object is to provide an apparatus of the character described hereinafter which will be highly efficientin use and economical in manufacture and of a simplified and improved construction.

A still further and equally important object of the invention is the provision for moving the syrup eiecting piston by resilient pressure, resulting from and by reason of a spring connection between the driving piston and the driven piston, with the resulting structure affording a predetermined movement of the driving piston prior to the movement of the driven piston,

against a body of syrup previously drawn into a measuring chamber. f Yet another and equally important object of the invention is the provision of a dispensing apparatus of the character hereinafter described, wherein there is obtained a high volume of gas in the carbonated water at the dispensing area, resulting` in the dispensing of a highly carbonated drink. with the minimum amount of foam.

Stilla further obiect of the invention is the provision of an apparatus of the character hereinafter described which. by its employment, assures a rapid dispensing of a mixed drink. usually consisting of a syrup and carbonatedwat'er. It is common knowledge that delay is encountered in preparing and serving a mixed drink by reason of the fact that in the dispensing of a drink consisting of a svrun and carbonated water. a large or deep foam head results. with the conseuuence that the operator must wait until the foam is substantially dissipated before adding to the drink additional carbonated water and syrup tc provide a mixed drink of proper volume. With this in mind. it is an object of the invention to dispense the syrup and carbonated water in the drinking glass in a manner such that a rel- The invention consists in the novel combinaon.. and arrangement of parts to be hereinafter escribed and claimed.

Between the cylinder body I4 and the block I2 is an insulating sleeve I 8 formed preferably of rub-v ber or the like and having a flange I9 disposedbetween the collar I6 and the outside wall plate'- The inner end portion 2l' of the cylinder body I4 projects inwardly beyond l the inner wall plate 22 of the wall II. Disposed f 20 of the wall II.

over this end portion of the cylinder body I4 is a cap 23 having an annular seat 24 formed therein in which a sealing ring 25 is positioned and bears against the wall plate 22. In the end portion 25 of the cylinder body I4 are threaded a'" pair of bolts 2'! which draw the cylinder body |41 l. in a direction to compress the collar IB against;
