Abstract

The dispenser comprises a two roller peristaltic pump driven by the manual pivoting of the handle via chains and sprockets, the sprocket on shaft A incorporating a one-way clutch. The dispenser may be arranged to dispense pre-determined amounts of liquid, e.g. alcoholic beverage, and may be in a case sealed against tampering. <IMAGE>

Description

MANUAL ALCOHOLIC DISPENSING UNIT ================================== The application relates to a manually operated dispensing unit, intended for use in dispensing alcoholic beverages.
The present system of dispensing beers & ciders, without the use of pressure, involves a lift pump connected to a handle.
which draws liquid from a reservoir to the dispense point.
Because of the nature of the pump, the liquid that remains in the system can deteriorate and have to be discarded, which can amount to quite a substantial loss over a period of time. They are also very difficult to keep hygienically clean, thus avoiding contaminating the product.
The unit comprises of a peristaltic pump assembly connected via a positive mechanical drive to a manually operated lever, which when moved causes the pump to rotate, and the liquid to be draw from the reservoir and expelled at the outlet.
The unit is to be self contained in a suitable casing to allow installation to be made either to a suitable existing support unit, or by the addition of a suitable support frame, be self supporting.
Because of the possible need for accurate volume dispensing, provision will be made to calibrate and seal the units against unauthorized interference to satisfy the relevant government department such as H.M CUSTOMS & EXCISE.
To provide more detail on the invention, the following description is provided, with reference to the drawing listed below FIGURE 1. Shows a schematic diagram illustrating the flow of liquid through the unit, and the direction of movement of the primary parts.
The diagram shows the power transmission from actuating handle, (shown in the start position), to the pump unit provided by chain & sprockets, this illustration was shown because of its simplicity, but alternative drives such as gear trains could also be used to provide the same results.
With reference to FIG 1, the pump unit consists of a two roller peristaltic pump with a chain sprocket, incorporating means to restrict the drive rotation to one direction only, rigidly fixed to the pump rotor mounted on SHAFT 'A'. The drive to the pump is provided by an open ended chain, fixed at one end with a spring tensioner, and at the other end to an actuating arm. The actuating arm is rigidly fixed to a chain sprocket mounted on SHAFT 'B'which is connected via an endless chain to a sprocket on SHAPT 'C'. Rigidly attached to the sprocket is the main actuating handle, which when pulled causes SHAFT 'C' to rotate, SHAFT 'B' also rotates and the actuating lever pulls the chain connected to SHAPT 'A' causing the pump to rotate and the spring tensioner to expand.When the handle is pulled to the maximum extent of its travel, (approx one third of a revolution) it is pushed back to the starting position. When the handle is being returned to the start position the pump is not rotating, but the tensioner is pulling the open ended chain back to its original position, this being possible by the 'freewheeling of the chain sprocket on SHAPT 'A'. The pump is now ready to dispense again.
By connecting the input side of the pump to a suitable reservoir of liquid, the peristaltic action will draw the liquid through the pump and dispense at the outlet, which when placed adjacent to the actuating handle, enables operation of the unit by one person.
The precise amount dispensed per full movement of the actuating handle would be preset by the bore size and radius of the pump and also the movement of the actuating arm mounted on SHAPT 'B', and with the unit contained in a case which when sealed cannot be tampered with without destruction of the seal, the unit can provide very accurate and calibrated measures of liquid

Claims (2)

  1. CLAIMS 1, A manually operated self contained dispenser, consisting of a peristaltic pump connected to a manually operated handle via a positive mechanicaludrive which when connected to a suitable reservoir of liquid will dispense pre determined amounts of liquid to the outlet.
  2. 2, A manually operated self contained dispenser as claimed in claim 1 to dispense un calibrated amounts into a calibrated measuring device.
