How would you use Daly's device? In the patent he describes the operation as follows:
"Now, upon making up a freight train in which this device may be used, the number, of the engine is first ascertained and its corresponding scale ring over that particular road is placed in position., Then for each car 'to' be transported, its gross weight is learned and the propelling, pin is placed in the hole 11 opposite a number designating 102 an amount equal to the gross weight of the .car. The pin and disk are turned clockwise until the propelling pin strikes against .the fixed stop 7 and the number of gross tons that car represents on that road will be registered upon the registering wheels. A car at a time may be added and the same process employed so long as: neither the limit in the number of cars has been reached, nor the sum upon the registering mechanism exceeds U 5 the tonnage rate of the engine."
