Abstract

Abstract Dough which is to be formed into small volumes for later baking into bread, etc. is moved from a mass of dough in the lower portion of a hopper by a pair of helical screws, through a conduit, first to a metering means and then through a dispensing nozzle. A paddle reciprocates through an arc adjacent the dispensing nozzle and on its downward stroke is oscillated so that its lower edge abuts the dispensing nozzle to sever the dough moved through the dispensing nozzle away from the oncoming dough, and then oscillates away from the dispensing nozzle as it returns to its ready position. The downward severing movement of the paddle is initiated by the metering means.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 169 words
A method of separating a viscous flowable paste material from a large mass of material into smaller masses of predetermined volumes of the material comprising the steps of continuously moving the material from the mass of material through a volume measuring means and then from the volume measuring means through the opening of a nozzle, continuously measuring the volume of the material moving through the volume measuring means, and in response to predetermined volumes of the material having moved through the volume measuring means continually, severing the material at the nozzle opening into volumes of material corresponding to the predetermined volumes of the material measured by the volume measuring means by moving a paddle member in biased contact with the nozzle across the nozzle opening from one side to the other side of the nozzle opening and returning the paddle to the one side of the nozzle opening through a path displaced from the nozzle opening so as to avoid contact with the material moving through the nozzle opening.
Claim 2
Independent Claim 169 words
A method of separating a viscous flowable paste material from a large mass of material into smaller masses of predetermined volumes of the material comprising the steps of continuously moving the material from the mass of material through a volume measuring means and then from the volume measuring means through the opening of a nozzle, continuously measuring the volume of the material moving through the volume measuring means, and in response to predetermined volumes of the material having moved through the volume measuring means continually, severing the material at the nozzle opening into volumes of material corresponding to the predetermined volumes of the material measured by the volume measuring means by moving a paddle member in biased contact with the nozzle across the nozzle opening from one side to the other side of the nozzle opening and returning the paddle to the one side of the nozzle opening through a path displaced from the nozzle opening so as to avoid contact with the material moving through the nozzle opening.
Claim 3
Dependent Claim 92 words
The method of claim 1 and wherein the step of continuously moving the material from the mass of material comprises placing a mass of the material in a hopper, rotating a pair of interference helical screw elements through the lower portion of the hopper to induce the dough to move along the lengths of the screw elements and out of the hopper, and creating a zone of reduced pressure in the hopper about a portion of the screw elements to induce the material in the hopper to move towward the screw elements.
Claim 4
Dependent Claim 59 words
The method of claim 1 and wherein the step of continously moving the material through a volume measuring means comprises moving the mass of material through a rotary vane metering means, and wherein the step of continously measuring the volume of material moving through the volume measuring means comprises measuring the rotational movement of the rotary vane metering means.
Claim 5
Dependent Claim 76 words
The method of claim 1 and wherein the step of continuously moving the mass of material through a volume measuring means comprises moving the mass of material through a magnetic flow meter and wherein the step of measuring the volume of material moving through the volume measuring means comprises inducing a magnetic field across the path of movement of the dough and detecting the voltage induced by the movement of the dough through the flow meter.
Claim 6
Dependent Claim 81 words
The method of claim 1 and wherein the step of continually severing the material at the nozzle opening comprises orienting a paddle at a downwardly sloped attitude and moving the lower edge of the paddle downwardly across the nozzle opening to sever the material moved through the nozzle opening from the oncoming material, and reorienting the paddle to move the lower edge of the paddle away from the nozzle opening and raising the paddle to a level above the nozzle opening.
Claim 7
Independent Claim 222 words
A method of separating a viscous flowable paste material from a large mass of material into smaller masses of predetermined volumes of the material comprising the steps of continuously moving the material from the mass of material through a volume measuring means and then from the volume measuring means through the opening of a nozzle, continuously measuring the volume of the material moving through the volume measuring means, and in response to predetermined volumes of the material having moved through the volume measuring means continually moving a paddle in a downward direction in front of the nozzle opening, biasing the paddle in a sloped attitude so that its lower leading edge portion is urged into engagement with the nozzle and the trailing portion of the paddle is displaced from the nozzle as the paddle moves downwardly across the nozzle opening, and turning the paddle away from the nozzle opening as the paddle moves in an upward direction with respect to the nozzle opening so that as the paddle moves downwardly the material is severed at the nozzle opening into volumes of material corresponding to the predetermined volumes of the material measured by the volume measuring means and so that as the paddle moves in an upward direction the material is free to move out of the nozzle opening without contacting the paddle.
