Abstract: A rebar support is provided through an arm-type apparatus, which may have a plurality of dimensions for different concrete constructions. A tube in the apparatus is slid over an upright support such as a grade stake to hold the apparatus in place. Multiple instances of the apparatus may thus be placed over multiple stakes to hold rebar in the correct position for the grid pattern required to strengthen the concrete in a particular structure. Rebar may then be quickly and securely snapped into notches on the apparatus without tying or extensive training of personnel. In an embodiment different designs of the apparatus are provided with notches designed to fit rebar of different diameters. In another embodiment snap-out tabs in the notches are used so that one design of the apparatus may be employed with rebar with different dimensions. The apparatus may be Y-shaped to further strengthen the arms.

Abstract: A repeating rubber projectile firing toy gun is formed by a hollow handle and frame portion integrally connected with a gun barrel portion. A sprocket wheel magazine journalled by opposing side walls of the frame section projects above the gun frame for receiving one end portion of a rubber band, having its other end portion engaged over a notch at the forward end of the gun barrel. A trigger mechanism biases a spring urged pawl out of engagement with the sprocket wheel to permit angular rotation thereof and release at least one of the projectiles while a second pawl on the trigger mechanism interrupts the sprocket wheel rotation after the release of only one rubber band projectile or a succession of rubber band projectiles by repeated trigger pulls.
