Abstract: A golf green repair tool having a plurality of spears centered around a plurality of tines. The tines and spears are biased by a spring inside a housing and sleeve. When the cap the housing is pressed by the foot of a greenskeeper or golfer the spring is compressed forcing the tines and spears into the turf. The tines are inserted around the periphery of the ball-mark to aerate and loosen the turf. The spears are inserted into the center of the ball-mark and aerate and pull the bottom of the ball-mark to the level of the surrounding turf. The bottom side of the ground-contacting sleeve pressed down the raised rim of the ball-mark correcting the entire ball-mark to the level of the surrounding turf.

Abstract: A wall system includes a grid constructed of horizontal main support channels mounted on a fixed wall and a plurality of spaced vertical standards secured to the channels at the front thereof. Each channel has a U-shaped cross-section with rearwardly extending arms diverging slightly so that overlapping channels may nest, one in the other. Ears projecting outward from the ends of the arms and lie in a common plane are used for securing the channel in place. The web of each channel is provided with a longitudinally extending row of equally spaced apertures. Each standard is provided with two longitudinally extending rows of holes with the rows being spaced by the distance between apertures and the holes in opposite rows being connected by lines that are perpendicular to the longitudinal axis of the standard. Fasteners extending through holes in each row are received by adjacent apertures in the channel web to automatically secure the standard in a position at right angles to the support channel.

Abstract: A soffit skeleton is constructed of a plurality of transverse frames mounted to a plurality of longitudinal spacer/cap tracks. Each frame is constructed of a metal channel having a U-shaped cross-section and bent into a plurality of end to end sections that are integrally connected at bend line joints. At some of these joints, the sections meeting thereat form interior angles and overlapping portions of each U-arm are secured together. The tracks are also U-shaped metal channels. Each of the latter is provided with equally spaced locating apertures in one arm thereof to receive an individual interior angle forming joint to thereby cap such joint and align said frames in a row in spaced parallel planes. The sections of each arm are separated by transverse notches. Prepunched fastener receiving apertures in the arms adjacent the notches are disposed so that when predetermined apertures are aligned there is a predetermined angle at the joint.
