p &# 34 ; of the air pump upon the operating arm being moved toward the second position shown in fig9 . as best seen by referring to fig1 and 6 , side assemblies 24 each comprise a first side member 24a and a cooperating second side member 24b . each side member 24a has a lower extremity 35 which is interconnected with floor member 16 by suitable connectors such as screws 37 ( fig1 ). the upper portion 39 of each side member 24a is provided with an elongated , generally vertically extending slot 40 . each side member 24b is provided with a threaded connector 43 which includes a shank portion 43a that extends through and is slidably received within slot 40 . a wing nut 44 is threadably received on each connector 43 and functions when tightened against a side member 24a to position the side member 24b at a selected height above the base assembly 14 . turning to fig1 and 11 , it is to be noted that with the construction described in the preceding paragraph , side member 24b along with cross member 26 to which it is connected can be adjusted relative to side member 24a so as to controllably adjust the height of cross member 26 and , in turn , the operating arms 30 relative to the upper surface of floor member 16 . accordingly , when the apparatus of the invention is used with smaller dispensers , such as dispensers &# 34 ; d - 1 &# 34 ; which are of the character shown in fig1 and 11 , the wing nuts 44 of each side assembly 24 can be loosened and side member 24b can be lowered to enable the so operating arms 30 to moved into the correct operating position with respect to dispensers &# 34 ; d - 1 &# 34 ;. with the operating arms thusly positioned , they can be selectively operated to depress the plunger &# 34 ; p &# 34 ; of the dispenser &# 34 ; d - 1 &# 34 ; over which the arm is superimposed in the manner indicated by the phantom lines of fig1 . to provide rigidity to side members 24a , diagonal braces 27 extend between floor member 16 and each side member ( fig4 ). turning now to fig7 and 8 , it is to be observed that each of the operating arms 30 is pivotally interconnected with cross member 26 by means of brackets 48 which are , in turn , interconnected with cross member 26 by threaded connectors such as connectors 51 . each of the brackets 48 includes a channel - like opening 52 which closely receives the end portion 30a of an operating arm 30 . the side portions of bracket 48 , which define the channel - like opening , as well as end portion 30a of operating arm 30 , are drilled to accept a pivot pin 54 . as best seen in fig7 pivot pin 54 extends through drilled bores 53 provided in the side portions of bracket 48 and also through a drilled bore 55 provided in end portion 30a of operating arm 30 . with this construction , each arm 30 is readily pivotally movable between the first elevated position shown in fig4 and the second beverage dispensing position shown in fig9 . turning once again to fig2 and 3 , it is to be noted that first dispensing engaging member 18 of the locating means of the invention is affixed to floor member 16 by any suitable means such as adhesive bonding or threaded connectors . to closely receive the base portion of a dispenser &# 34 ; d &# 34 ;, a plurality of arcuate shaped cut - outs 63 are provided at longitudinally spaced locations along the length of first dispenser engaging member 18 ( fig1 ). the second dispenser engaging means , the configuration of which is best seen in fig3 rather than being fixedly connected to floor member 16 is slidably connected thereto so that the second dispenser engaging member can be moved toward and away from first dispenser engaging member 18 to accommodate dispensers of various sizes . more particularly , second dispenser engaging member 20 is provided with a plurality of longitudinally spaced , generally v - shaped cut - outs 65 the sides of which are movable into engagement with the base portions of the dispensers &# 34 ; d &# 34 ; as member 20 is moved in a sliding relationship with floor member 16 in a direction toward first dispenser engaging member 18 . to permit this sliding movement , dispensing engaging member 20 is provided with a pair of longitudinally spaced slots 67 which closely receive the shank portions 69a of a pair of spaced - apart threaded connectors 69 which are connected to and extend upwardly from the top surface of floor member 16 ( fig1 ). wing nuts 70 are provided on threaded connectors 69 so that dispenser engaging member 20 can be securely clamped at a selected location against floor member 16 . by loosening wing nuts 70 , member 20 can be moved either toward or away from dispenser engaging member 18 to accommodate dispensers having different size base portions . referring to fig1 and 11 , it is to be noted that in the form of the invention there shown , the first dispenser engaging member 18a is also slidable with respect to floor member 16 . for this purpose member 18a is slotted to receive shank portion of connectors such as connector 69 ( fig1 ) and functions in the same manner as sliding member 20 . as best seen by referring to fig3 second dispenser engaging member 20 is also uniquely provided with an elongated fluid capture channel 74 which , as illustrated in fig9 is adapted to contain fluid spills which may occur during the beverage dispensing operation ( see fig9 ). this capture channel functions to effectively capture and retain spilled liquids and thereby help to prevent the spill of liquids onto the floor and onto table tops located within the serving area . it is to be understood that the frame work of the apparatus of the invention can be constructed from plastic , wood , metal or any other suitable material . having now described the invention in detail in accordance with the requirements of the patent statutes , those skilled in this art will have no difficulty in making changes and modifications to the individual parts or their relative assembly in order to meet specific requirements or conditions . such changes and modifications may be made without departing from the scope and spirit of the invention , as set forth in the following claims .
