DISPENSING MECHANISM FOR SYRUPS.

ecaece.

To all whom it may concern:

Be it known that I, LOUIS A. BECKER, a citizen of the United States, residing at Chicagofin the county of Cook and State of Illinois, have invented certain new and useful Improvements in Dispensing Mechanism for Syrups, of which I do declare the following to be a full, clear, and exact description, reference being had to the drawing forming part of this specification.

My present invention has relation more particularly to the improvement of dispens ing apparatus such as is used for withdrawing from the syrup jars of soda water fountains a measured quantity of syrup and the object of the invention is to provide a simple, cheap, effective and durable construction of dispensing apparatus.

To this end the invention consists in the features of improvement hereinafter described, illustrated in the accompanying drawing and particularly pointed out in the claims at the end of this specification.

Figure 1 is a view in vertical section through a portion of a soda water fountain having my invention applied thereto, the mechanism embodying my invention being shown in elevation. Fig. 2 is a view in cen tral vertical section through my improved dispensing apparatus, the section being taken on line 2 2 of Fig. l. Fig. 3 is a view in perspective showing upon an enlarged scale the lower portion of my improved apparatus.

In the accompanying drawing A designates that portion of the soda water fountain adapted to receive the syrup containing jars,-a portion of one of said jars being shown and designated as B in the drawing. Preferably the jar B is provided with a pocket or depression Z2 in its bottom to better admit the syrup to the measuring cup of my improved apparatus. In the drawing the receptacle A is shown as provided with a downwardly folding door A that is hinged at a, this being one simple and familiar form of receptacle.

Through an opening in the top of the chamber A and above the syrup jar B eX- tends the upper portion of my improved dispensing apparatus, and as shown, a plug or bushing a2 may be inserted in the opening at the top of the chamber A to better guide the reciprocating movement of the dispensing apparatus.

Specification of Letters Patent.

Application filed October 30, 1905.

Patented J uly 5, 1910.

Serial No. 284,969.

My improved apparatus comprises a tube C having a measuring cup D connected at its lower end, and this measuring cup is adapted to receive a piston E that will reciprocate within the cup. A stem E of the piston E is tubular and leads upward from a central opening in the piston and through the tube C to the lower end of which is connested the cap or cover D of the cup D. The upper end of the hollow piston stem E is connected to the head portion of a discharge spout G through which the syrup will be discharged into drinking glasses or like receptacles. As shown, an outer tube I-I extends downwardly from the discharge spout G at its lower end overlapping in manner free to move, the upper end of the tube C. Within the outer tube I-I and encircling the upper portion of the hollow piston stem E, is placed a coiled spring J, the upper end of which bears against the lower portion of the head of the discharge spout Gr, while its lower end bears against the upper end of the tube C.

In the preferred form of my invention the cap or cover D of the cup D, is formed with an interiorly threaded flange d adapted to .iit around and engage the correspondingly threaded upper portion of the cup E, so that the cup may be detacliably connected to its cap. By this means, cups of different sizes may be employed according to the demands of the customer and the character of syrup or other fluid that is dispensed. As shown, the cap or cover D of the cup D is substantially the same in interior diameter as the cup D, so that the piston E may move freely from the cap or cover D into the cup D and across the threaded joint that unites the two. The cap or cover D is formed more or less open to admit the syrup into the cup D beneath the piston E, and this may be accomplished by employing any desired number of holes or openings Z2 in the cap or cover D. Preferably, the cap or cover D is attached to the tube C by a screwthreaded joint c that enables these parts to be conveniently formed and to be readily taken apart for cleaning or other purposes.

By preference, the upper end of the hollow stem E is attached to the head of the discharge spout G by a screw-threadedjoint e and by preference also, the outer tube II is connected to the head of the discharge spout Gr by a similar threaded joint h. A

port g in the head of the discharge spout Gr connects with the main channel g of said spout. As shown, the discharge spout Gr is provided with a pressure plate Gr whereby the attendant may conveniently depress the discharge spout Gr, as will presently appear, and preferably this pressure plate G is formed with a threaded stein g2 adapted to set within a correspondingly threaded opening in the top of the head portion of the discharge spout G.

From the foregoing description, the operation of my improved dispensing apparatus will be seen to be as follows: lVhen the parts are in the normal position shown in the drawings, the piston E will be held by the coiled spring J in the upper portion of the cap or cover D of the cup D, so that syrup or like liquid from the jar B may pass through the opening Z2 into the cup D. If now the discharge spout Gr be forced downward by the pressure of the hand of the attendant upon the pressure plate Gr', the piston E will move down into the cup D and will force the liquid contained therein up through the hollow piston stem E and through the discharge spout Gr into the drinking glass or like receptacle placed beneath the spout. Then the attendant relieves the pressure of his hand from the discharge spout G the coiled spring J will restore the parts to the normal position shown in the drawing. It will thus be seen that each time the attendant depresses the discharge spout of the apparatus, a measured quantity of syrup or like liquid will be delivered through the discharge spout.

It should be noted that -the improved dispensing device is in no way dependent upon any support at its upper end. 1t is only necessary that the dispensing device rest upon the bottom of the receptacle containing the liquid to be delivered. The operating-spring J serves to hold the piston within the upper end of the dispensing cup against its cap and is protected from contact with the liquid in the jar by the tube or sleeve H. The dispensing device consists of few parts which may be readily detached from one another for cleaning. By having a closed bottom to the dispensing cup D with inlet openings at its upper end above which the piston E is normally held, it is not necessary to provide valves of anv sort in the device. This is quite an advantage since such valves readily deteriorate, leak and wear out.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
