Abstract: A panel having a suspending hook at a lower end thereof slidably receives an optimum-weight comparison chart. The hook is used to support a basket or sling in which a child is held for weighing. A spring-loaded limb overlies the panel, and has a stylus in an end thereof, with a second hook at the opposite end thereof. The second hook is used to suspend the panel from a tree branch, a beam, or such, and the weight of a child causes the panel to descend, against the biasing of the spring-loaded limb. The stylus is depressed to make a hole in the chart for comparison with an optimum trajectory of weight/development of children of like age, and to keep a record of the measured weight, and to track weight gain or loss with successive weighings and stylus hole-punching of the chart.

Abstract: Apparatus for folding a paper sheet includes a pair of spaced parallel flaps pivotally mounted on a frame. A die has an inner side and is mounted on the frame between the flaps to allow insertion of the paper sheet to a loaded position on the inside of the die and in front of the flaps. An actuator is coupled to the flaps for alternately closing them against the inner side of the die to doubly fold the paper sheet.
