Abstract: ABSTRACT OF THE DISCLOSURE           An apparatus that facilitates the manufacture of wooden stairs of the type having treads and risers extending between and affixed to side housings or stringers.  The apparatus provides multiple, parallel guides for the router used to cut the grooves in the stringers into which are fitted the treads and risers.          By using a parallelogram construction for the multiple guides, the apparatus can be quickly adjusted and set to produce almost any size of stairs.  An index bar used with the apparatus allows the apparatus to be quickly set for the particular stairs desired so that the grooves for both the treads and risers can be cut quickly and accurately in the stringers.  The router is moved along each of the parallel guides to cut the grooves for all of the treads, and then the apparatus is quickly and easily reset and locked into position to set the guides for cutting of the grooves for the risers.

Abstract: ABSTRACT OF THE DISCLOSURE           A mechanism for angling, pitching, and tilting a dozer blade utilized in a conventional bulldozer is provided wherein the blade is connected by means of a universal joint to the center bright portion of a C-shaped frame.  A vertical mast support structure at the center of the bight portion of the frame mounts one end of the extensible links used for angling, tilting, and pitching the blade.  The angling and pitching control includes a pair of piston-cylinders connected between the vertical mast and the respective sides of the bulldozer blade.  The hydraulic circuitry for the cylinders simultaneously extends the piston rod of one cylinder while retracting the piston rod of the opposed cylinder to angle the blade about a vertical axis.  Simultaneous extension or retraction of both piston rods causes the blade to pitch about a horizontal transverse axis.  The blade is additionally connected to the top end of the vertical mast structure by a tilt cylinder which is disposed parallel to the top edge of the blade.  The blade adjustment construction provides that when the blade is angled, the blade tilt is not changed.  The present construction eliminates conventional complex push lever and linkage arrange-ments, and the operation does not require a complex hydraulic system.
