Abstract

Abstract A platform scale having an interconnected lever type suspension in which all of the suspension links are adjustable for optimum alignment of the mechanism. Each suspension member has an adjustable pin with a V-notch to receive a thin blade type hanger link, each pin having locking means by which the mechanism can be set with all the hanger links accurately vertical, so that no offset loads or drag are applied to the scale. The mechanism is applicable to electronic readout systems utilizing strain gauges or similar force indicating means, or to beam type scale mechanisms with adjustable weights.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 137 words
A platform scale, comprising: a housing, a weighing platform mounted above said housing, a suspension frame attached to said platform and extending downwardly into the housing, lever means pivotally suspended in said housing and having an output arm for attachment to weight readout means, said suspension frame being pivotally attached to said lever means, certain of the pivotal attachments between said lever means and said suspension frame each including a hanger pin longitudinally secured in the lever means and having a V-notch therein, a link plate pivotally attached to the suspension frame and having a blade portion engaged in the V-notch fixing the longitudinal position of the blade portion along the length of the hanger pin, and means for selectively adjusting the longitudinal fixed position of the hanger pin thereby selectively moving the position of the link.
Claim 2
Dependent Claim 137 words
A platform scale, comprising: a housing, a weighing platform mounted above said housing, a suspension frame attached to said platform and extending downwardly into the housing, lever means pivotally suspended in said housing and having an output arm for attachment to weight readout means, said suspension frame being pivotally attached to said lever means, certain of the pivotal attachments between said lever means and said suspension frame each including a hanger pin longitudinally secured in the lever means and having a V-notch therein, a link plate pivotally attached to the suspension frame and having a blade portion engaged in the V-notch fixing the longitudinal position of the blade portion along the length of the hanger pin, and means for selectively adjusting the longitudinal fixed position of the hanger pin thereby selectively moving the position of the link.
Claim 3
Dependent Claim 89 words
A platform scale according to claim 1, wherein certain of the pivotal connections of said lever means to the housing each includes a support pin longitudinally secured in the lever means and having a V-notch therein, a link plate pivotally attached to the housing and having a blade portion engaged in the V-notch fixing the longitudinal position of the blade portion along the length of the support pin, and means for selectively adjusting the longitudinal fixed position of the support pin thereby selectively moving the position of the link.
Claim 4
Dependent Claim 41 words
A platform scale according to claim 2, wherein each of said link plates has an opening to receive the respective pin, with the blade thereof extending across one end of the opening, the sides of the opening converging toward the blade.
Claim 5
Dependent Claim 129 words
A platform scale according to claim 1, wherein said lever means comprises a pair of generally T-shaped levers each having a cross bar and a stem perpendicular to the cross bar, the stems extending toward each other in substantially parallel alignment and being pivotally interconnected, the pivotal interconnection of said stems includes a connecting pin longitudinally adjustably secured in each stem, said connecting pins overlapping and having V-notches on opposite sides thereof, a link plate having blade portions engaged in the V-notches and connecting the levers, which V-notches fix the longitudinal position of the blade portions along the length of the respective connecting pin, and means for selectively adjusting the longitudinal fixed position of each of the connecting pins to thereby selectively move the position of the link plate.
Claim 6
Dependent Claim 38 words
A platform scale according to claim 4, wherein one of said levers is suspended higher than the other, and said output arm being fixed to the cross bar of the higher lever and extending over the other lever.
Claim 7
Dependent Claim 61 words
A platform scale according to claim 4, wherein said suspension frame includes hanger bars parallel to and spaced below said cross bars, said hanger pins being longitudinally slidable through the cross bars, means for fixing the longitudinal position of said hanger pins to given positions in said cross bars, and the associated link plates being pivotally attached to said hanger bars.
Claim 8
Dependent Claim 27 words
A platform scale according to claim 6, wherein said hanger bars have longitudinally extending vertical slots therein, said last mentioned link plates being held in said slots.
Claim 9
Dependent Claim 28 words
A platform scale according to claim 6, wherein said support pins are slidable through said cross bars, and the associated link plates have flexible connections to said housing.
Claim 10
Dependent Claim 23 words
A platform scale according to claim 8, wherein said support pins and hanger pins are parallel and perpendicular to the respective cross bars.
Claim 11
Dependent Claim 18 words
A platform scale according to claim 9, wherein one of said levers is suspended higher than the other;
Claim 12
Dependent Claim 41 words
the pivotal interconnection of said stems including a connecting pin longitudinally slidable in each stem, said connecting pins overlapping in vertically spaced relation and having V-notches in opposite sides thereof, and a link plate having blade portions engaged in the V-notches.
Claim 13
Dependent Claim 41 words
the pivotal interconnection of said stems including a connecting pin longitudinally slidable in each stem, said connecting pins overlapping in vertically spaced relation and having V-notches in opposite sides thereof, and a link plate having blade portions engaged in the V-notches.
Claim 14
Dependent Claim 40 words
A platform scale according to claim 10, and including lock screws for securing said support pins, said hanger pins and said connecting pins; said housing having an opening below the platform through which all of said lock screws are accessible.
