Abstract
Abstract A truck weighing scale capable of measuring various axle configurations and providing individual axle weights and total truck weights. The individual axle weights are determined by successively accumulating total weights each time an axle enters on the scale and subtracting the next preceding accumulated axle weight.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
240 words
A truck weigh scale comprising a weigh platform for a truck; a weigh scale for said weigh platform; detector means for truck axles on said platform; axle configuration selector means responsive to predetermined programming for arranging the axles of a truck in a series of predetermined axle configurations as its axles are detected by said detector means; and weight register means responsive to said axle configuration selector means to register weight on said weigh scale, said weight register means comprising a first memory register for weight on said weigh platform having an updating time base, a logic control, a calculating network, a data interface and an information recorder, said logic control being responsive to said axle configuration selector means to operate said calculating network to accept the weight information in said first memory register upon the operation of said logic control, said time base being less than the time between entry of succeeding axle configurations in use, a second memory register adapted to accept and record the weight information transferred to said calculating network when said calculating network is operated by said logic control for use by said Calculating network at the next following time of operation of said logic control, said calculating network being adapted to calculate the difference between the weight information on said memory registers at the time of operation of said logic control and transmit it to said data interface for use by said information recorder.
Claim 2
Dependent Claim

A truck weigh scale comprising a weigh platform for a truck; a weigh scale for said weigh platform; detector means for truck axles on said platform; axle configuration selector means responsive to predetermined programming for arranging the axles of a truck in a series of predetermined axle configurations as its axles are detected by said detector means; and weight register means responsive to said axle configuration selector means to register weight on said weigh scale, said weight register means comprising a first memory register for weight on said weigh platform having an updating time base, a logic control, a calculating network, a data interface and an information recorder, said logic control being responsive to said axle configuration selector means to operate said calculating network to accept the weight information in said first memory register upon the operation of said logic control, said time base being less than the time between entry of succeeding axle configurations in use, a second memory register adapted to accept and record the weight information transferred to said calculating network when said calculating network is operated by said logic control for use by said Calculating network at the next following time of operation of said logic control, said calculating network being adapted to calculate the difference between the weight information on said memory registers at the time of operation of said logic control and transmit it to said data interface for use by said information recorder.
Claim 3
Independent Claim
80 words
A method of measuring the loading of a series of axle configurations of a truck comprising the steps of moving the truck onto a weigh platform having a length to admit said series of axle configurations, recording the total weight on the platform at the time of entry thereon of each axle configuration, and subtracting from the total weight as just aforesaid the total weight on the platform at the time of entry thereon of the next preceding axle configuration.
Claim 4
Independent Claim
80 words
A method of measuring the loading of a series of axle configurations of a truck comprising the steps of moving the truck onto a weigh platform having a length to admit said series of axle configurations, recording the total weight on the platform at the time of entry thereon of each axle configuration, and subtracting from the total weight as just aforesaid the total weight on the platform at the time of entry thereon of the next preceding axle configuration.
Claim 5
Dependent Claim
43 words
A method of measuring the loading of a series of axle configurations of a truck as claimed in claim 2 including recording in addition the total weight on the platform at the time of entry of the last axle configuration in the series.
Claim 6
Dependent Claim
175 words
A truck weigh scale comprising a weigh platform for a truck having a length to receive a series of truck axle configurations, a weigh scale for said weigh platform with an output, a first register means connected to said output of said weigh scale, a second register means connected to the output of said weigh scale with a memory, a logic control operable upon the entry of each successive axle configuration to said weigh platform, a calculating network, a data interface, said calculating network being responsive to operation of said logic control to register the total weight on said weigh platform on said first register means at the time of operation of said logic control, calculate the difference between the total weight on said weigh platform at the next preceding time of operation of said logic control and the time of operation of said logic control, communicate the said difference to a data interface for use and transfer the total weight at the time of operation of said logic control to said second register means.
Claim 7
Dependent Claim
175 words
A truck weigh scale comprising a weigh platform for a truck having a length to receive a series of truck axle configurations, a weigh scale for said weigh platform with an output, a first register means connected to said output of said weigh scale, a second register means connected to the output of said weigh scale with a memory, a logic control operable upon the entry of each successive axle configuration to said weigh platform, a calculating network, a data interface, said calculating network being responsive to operation of said logic control to register the total weight on said weigh platform on said first register means at the time of operation of said logic control, calculate the difference between the total weight on said weigh platform at the next preceding time of operation of said logic control and the time of operation of said logic control, communicate the said difference to a data interface for use and transfer the total weight at the time of operation of said logic control to said second register means.
