Claims25
In a weighing apparatus comprising a base, said base supporting balancing link means, said balancing link means being operatively engaged with rocker means, whereby vertical deflection of said balancing link means from a weight applied thereto is translated into horizontal motion of said rocker means, said rocker means being coupled to rack means driving pinion means, said pinion means including indicator means for indicating a measure of said weight applied to said balancing link, the improvement comprising main spring means suspended vertically from bracket means, said bracket means being supported by said base at two or more points, said bracket means including an opening through which said main spring means may pass, said main spring means being vertically suspended on said bracket means by hanger means traversing said opening and supported by said bracket means, said main spring means including means for operatively engaging said main spring means, whereby said balancing link means deflect proportionally to said weight applied to said balancing link means.
Support means for vertically supporting a main spring for a weighing apparatus, comprising a bracket having a horizontal member, the horizontal member having an opening therethrough for receiving said main spring, said support means further including a horizontal beam traversing said opening, said main spring hanging from said horizontal beam wherein said bracket opening is circular and has a first diameter, said horizontal beam being slideably received and supported by a circular ring, said circular ring having a lower flange extending into said bracket opening, said circular ring and lower flange being sized to allow horizontal and rotational movement of said circular ring within said bracket opening.
Support means for vertically supporting a main spring for a weighing apparatus, comprising a bracket having a horizontal member, the horizontal member having an opening therethrough for receiving said main spring, said support means further including a horizontal beam traversing said opening, said main spring hanging from said horizontal beam, wherein said bracket has at least three spaced-apart legs supporting said horizontal member, one of said legs including zero adjustment means.
A method of manufacturing a vertical main spring suspension system for a weighing apparatus, comprising the steps of:
- (a) providing a vertical main spring;
- (b) providing bracket means having an opening therein sized for receiving said vertical main spring;
- (c) positioning said main spring within said opening in said bracket means;
- (d) providing suspension means for vertically suspending said vertical main spring from said bracket means;
- and
- (e) suspending said main spring from said suspension means, wherein said bracket means includes three support legs for supporting said bracket on the base of a weighing apparatus.
A method of manufacturing a vertical main spring suspension system for a weighing apparatus, comprising the steps of:
- (a) providing a vertical main spring;
- (b) providing bracket means having an opening therein sized for receiving said vertical main spring;
- (c) positioning said main spring within said opening in said bracket means;
- (d) providing suspension means for vertically suspending said vertical main spring from said bracket means;
- and
- (e) suspending said main spring from said suspension means, wherein said suspension means comprises a ring having a lower flange and an upper flange having two slots therein for receiving a horizontal beam, wherein said lower flange is positioned within said bracket opening, said horizontal beam is positioned within said slots of said upper flange, and said main spring is suspended from said horizontal beam.
