Description

SPECIFICATION Food extruding device The present invention relates to a food extruding device.
There are various situations in which it is desirable to extrude an amount of food, e.g. when icing a cake, where the icing is extruded through a shaped nozzle from an icing bag by squeezing the bag or from a cylinder by forcing the piston along the cylinder in the direction of the nozzle. Also known are devices for delivering a measured amount of biscuit or cookie paste or dough to a baking tray prior to cooking. Such devices also work on the principle of forcing a piston along a barrel filled with the paste or dough and provided at one end with a nozzle. Such devices generally include what might be called a pistol-grip and an advancement mechanism, actuation of which causes a measured amount of paste or dough to be delivered.
We have sought to provide an improved extruder for paste-like food.
Accordingly, the present invention provides an extruder for paste-like food substances which comprises a barrel to hold the paste-like food substance and provided at one end with an outlet from which the paste-like food is caused to exit in measured amounts, a piston located in the barrel and capable of being forced along the barrel to extrude the paste-like food through the outlet, a piston-rod attached to the piston and provided with teeth, a pistol-grip at the other end of the barrel, one part of the pistol-grip is stationary relative to the barrel and the other part of the pistol-grip includes a lever pivoted intermediate its ends to the stationary part and is pivotal against the action of the spring when the pistol-grip is squeezed and a pawl resiliently urged into engagement with the teeth of the pistonrod when the pistol-grip is in its relaxed position, in use when the pistol-grip is squeezed one end of the lever engages one end of the pawl to bring the pawl out of engagement with the teeth of the piston-rod so as to permit the piston to advance a predetermined distance along the barrel to deliver a predetermined amount of paste-like food through the outlet.
Preferably the pawl is attached to a spring operated slide mechanism which includes an abutment means which is resiliently shifted by the teeth of the piston-rod to permit the piston-rod to advance along the barrel but which engages and obstructs the teeth to prevent the return of the piston-rod, the abutment means is manually disengaged from the teeth of the piston-rod by means of the slide mechanism to permit return of the piston along the barrel from the outlet end to the pistol grip end.
The device is simple to operate and requires only one hand to operate it, so leaving the other hand free to guide the barrel to ensure accurate extrusion of the contents of the barrel.
The present invention is further illustrated in the accompanying drawings, wherein: Figure l is a vertical cross-section through part of an extruder in accordance with the present invention showing the extruder in its relaxed or non-use position, Figure2 is a vertical cross-section through the extruder of Figure 1 showing operation of the handle to actuate the advancing mechanism, Figure 3 is a sectional detail of lines 3-3 of Figure 1, Figure 4 is a vertical cross-section through the extruder of Figure 1 showing operation of the release mechanism.
The extruder shown in the drawings comprises a hollow barrel 1. Attached to one end of the barrel 1 is an outlet (not shown) through which paste-like food substance held in the barrel can be extruded. The outlet can be removed to clean the barrel 1 and to permit the filling of the barrel 1 with a paste-likefood substance and may be fitted with plates of different shapes so as to extrude the paste-like food in different patterns. The other end of the barrel 1 is so shaped as to form a stationary part 2 of a pistol-grip shown generally as 3. The other part 4 of the pistol-grip 3 is moveable into and out of the part 2 of the pistol-grip 3 and includes a lever 5.
This lever 5 is pivotally mounted around a pivot point 6 on the stationary part 2 of the pistol-grip 3.
The lever 5 causes the part 4 of the pistol-grip 3 to be in the open position shown in Figure 1 when the device is in its relaxed or non-use position as it is under the influence of a spring 7, one end of which passes around the pivot point 6 and the other end of which passes through a support 8 on the stationary part 2 of the pistol-grip 3.
Slidably mounted within the barrel 1 and passing through a hole in the stationary part 2 is a piston-rod 9. One end of the piston-rod 9 is attached to a piston (not shown). Movement of the piston-rod 9 and piston along the barrel 1 pushes the paste-like food through the outlet. The other end of the piston-rod 9 is provided with a cap 10.
The piston-rod 9 is of U-shaped cross-section with the ends of the arms of the U-shaped piston-rod having teeth 11. Each of the teeth 11 has a cam portion 20 and a straight portion 21.
A pawl 12 is slidably mounted on the stationary part 2 of the pistol-grip 3 by means of a slot 13 accommodating a pin 14 of the stationary part 2. In the relaxed or non-use position shown in Figure 1 edge 15 of the pawl 12 is urged into contact with the straight portion 21 of a tooth 11 of piston-rod 9 by means of a spring 16.
The advancement of the piston-rod 9 along the barrel 1 is shown in Figure 2. As the part 4 of the pistol-grip 3 is squeezed in the direction shown by arrow 'A' end 17 of the lever 5 moves in an anti-clockwise direction against the action of the spring 7 to engage edge 18 of pawl 12. Edge 18 of the pawl 12 then moves in a clockwise direction because of the movement of pin 14 in slot 13 to run along the cam portion 20 of one of the teeth 11 to engage the straight portion 21 of the next tooth 11. This causes movement of the piston-rod 9 in the direction shown by arrow 'B' thereby to deliver a measured amount of the paste-like food in the barrel 1 throughtthe outlet. The relaxed or non-use position of the part 4, lever 5 and pawl 12 are shown in dotted lines in Figure 2.
When part 4 of the pistol-grip 3 is released the lever returns to its relaxed or non-use position under the influence of the spring 7 and the edge 15 of the pawl 12 remains in contact with the straight part 21 of 1 of one of the teeth 11. Movement of the piston-rod 9 in a direction opposite to that shown by arrow 'B' in Figure 2 is prevented by a plate 22 shown most clearly in Figure 3. The plate 22 is located in the stationary part 2 of the pistol-grip 3 and is slidably moveable in a direction which is transverse to the direction of movement of the pistol-grip 9. As shown in Figures 1 and 2 the plate 22 is urged towards the left by means of spring 23.
The plate 22 is provided with an opening 24 through which the piston-rod 9 passes. Edge 25 of the opening 24 is urged into engagement with the straight part 21 of 1 of the teeth 11 under the influence of the spring 23. In the position shown Figure 1 the edge 25 of the plate 22 engages one of the teeth 11 of the piston-rod 9 along the straight part 21. When the part 4 of the pistol-grip 3 is squeezed as shown in Figure 2 the advancement of the pistol-rod 9 in the direction shown by arrob 'B' causes the edge 25 of the plate 22 to ride over the cam surface 20 of the tooth 11 against the action of spring 23 thus advancement of the piston-rod 9 in the direction shown by arrow 'B' is not prevented.
When the part 4 of the pistol-grip 3 is released and the device is again in its relaxed or non-use position as shown in Figure 1 the edge 25 of the plate 22 again engages the straight portion 21 of another of the teeth of 11 of the piston-rod 9 and so prevents return movement of the piston-rod 9 in a direction opposite of that shown by arrow 'B'.
When the piston-rod 9 has been advanced the required distance in the direction shown by arrow 'B', i.e when the extrusion of the paste-like food from the barrel is complete, the piston-rod 9 is returned to its start position to permit refilling of the barrel 1 with paste-like food. To achieve this button 26 is pressed in the direction shown by arrow 'C' in Figure 4 against the action of the spring 23 and this causes the edge 25 of the plate 22 to come out of contact with the piston-rod 9 so as to permit movement of the piston-rod 9 in the direction shown by arrow 'D' in Figure 4. The piston-rod 9 is moved in the direction of the arrow 'D' by the user's pulling on cap 10. The barrel 1 is then ready to receive a further amount of paste-like food for extrusion.
The extruder of the present invention is easy to use. It can be readily dismantled for cleaning and reassembling for use and those parts which come into contact with food are preferably made of synthetic plastic material which is hygienic and easily cleanable.
