Abstract
Abstract A container filler and weighing system is disclosed. The weighing system is made up of a scale with a support for a container supported on the scale. A vibrator connected to the support so that the material fed into the container from a feeder is packed and settled in the container. An electronic readout is connected to the scale and a digital readout connected to the electronic circuit whereby the readings can be recorded and an annunciator is connected to the electronic circuit to signal when the container is full. The vibrator connected to the container support delivers a vertical component of force that has an especially good and efficient packing reaction on the material in the container.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
89 words
A packer/weigh-scale made up of a scale platform, a vibrator attached to said scale platform adapted to vibrate said scale platform in a vertical plane only, an upper frame, resilient means supporting said an upper frame on said scale platform, a scale base, at least one load cell supported on said scale base, flexible tension means supporting said upper frame on said load cell whereby vibrations from said vibrator are transmitted to said scale in a vertical plane only, whereby material supported on said upper frame will be vibrated.
Claim 2
Dependent Claim
89 words
A packer/weigh-scale made up of a scale platform, a vibrator attached to said scale platform adapted to vibrate said scale platform in a vertical plane only, an upper frame, resilient means supporting said an upper frame on said scale platform, a scale base, at least one load cell supported on said scale base, flexible tension means supporting said upper frame on said load cell whereby vibrations from said vibrator are transmitted to said scale in a vertical plane only, whereby material supported on said upper frame will be vibrated.
Claim 3
Dependent Claim
22 words
The packer/weigh-scale recited in claim 1 wherein said packer/weigh-scale comprises a sensing element and a readout means connected to said load cell.
Claim 4
Dependent Claim
38 words
The packer/weigh-scale recited in claim 2 wherein an arm is fixed to said load cell and extends laterally from said load cell, said flexible tension means comprises cable means attached to said arm and to said scale platform.
Claim 5
Dependent Claim
34 words
The packer/weigh-scale recited in claim 1 wherein a container and a section of track are supported on said platform, said track section being adapted to convey containers to be weighed to said weigh scale.
Claim 6
Dependent Claim
19 words
The packer/weigh-scale recited in claim 4 wherein said track is disposed in operative relation to other sections of track.
Claim 7
Dependent Claim
13 words
The packer/weigh-scale recited in claim 4 wherein said track comprises a roller conveyor.
Claim 8
Dependent Claim
33 words
The packer/weigh-scale recited in claim 1 wherein said scale platform is supported by at least four said load cells spaced from one another, each said load cell being connected to said readout means.
Claim 9
Dependent Claim
56 words
The packer/weigh-scale recited in claim 7 wherein each said load cell has a laterally extending arm attached thereto, said scale platform has yokes, one of said yokes being disposed above each said arm and extending downward and then laterally below said arm, a tension means is attached to each said arm and to a said yoke.
