ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates generally to hand tools, and more particularly to a hand tool with features for sizing and resizing the tongue and groove features of construction panels and boards.
2. Description of Related Art
The following art defines the present state of this field:
Sipe et al., U.S. Pat. No. 769,191 provides in a channeling-took, a body, side flanges extending upward from the body, the side flanges provided with grooves upon their inner faces, the grooves being inclined downward and forward, a knife arranged within the grooves and extending between the side flanges, a screw extending transversely from one side flange to the other for binding the knife in place, the depth of the cut being regulated by the distance the knife protrudes from the lower and forward end of the body a horizontal adjustable guide carried by the body underneath the knife adapted to travel in contact with the edge of the leather and regulate the distance of the cut from the edge and a handle secured to the body and extending rearwardly therefrom.
Hauver, U.S. Pat. No. 849,681 describes a stock having a curved bearing-surface and with a transverse guideway near the bearing-surface, and operating-handle extending from the stock at one end, a head member adjustable disposed through the guideway and provided with transverse sockets, cutters adjustably disposed in said sockets with their operating ends extending in advance of the bearing-face of the stock, means for adjustably securing the head in the guideway and means for adjustably securing the cutters in the sockets.
Moore, U.S. Pat. No. 1,114,903 describes a reefing tool which comprises a handle with an integral head laterally extended and bifurcated at the extremity, and with a vertical blade adapted to enter and to be guided by a seam.
Tingle, U.S. Pat. No. 1,148,552 describes a tool or implement for stepping a tire casing in repairing blow-outs, comprising a shank provided with a guide member, and a cutter-blade connected with the guide member and extending below the same with the guide member extending upon opposite sides of the cutter-blade for substantial distances.
Gallagher, U.S. Pat. No. 3,155,997 describes a tool for raking out and smoothing mortar joints of masonry walls, a straight handle portion of flat relatively wide strap metal of rectangular cross section having one end of gooseneck shape terminating in a relatively narrow rake-out tongue with flared shoulders formed at an angle of about 45 degrees, the other end of the tool having a shank of the width of the rake-out tongue bent at substantially right angles to the handle portion in the same direction as the gooseneck end of the tool is bent and a trowel portion of approximately the width of the mortar joint integral with said shank extending from said shank at right angles substantially parallel to and spaced from the handle portion of the tool to dispose the handle at an angle to avoid contact of the hand with the wall.
Ellis, U.S. Pat. No. 3,310,826 describes a golfer's cleaning tool comprising an elongated blade member including a substantially flat central portion, a first end portion extending at an obtuse angle out of the plane of said central portion and terminating in a bifurcated shoe cleat cleaning extremity characterized by a substantially V-shaped opening between two relative blunt points, a second end portion extending arcuately from the plate of said central portion in a direction opposite to said first end portion and terminating in a relatively blunt point adapted for cleaning the junction between the sole and upper of a golfer's shoe, said second end portion having an opening therein adapted to receive a suspension device, and a pair of oppositely disposed reverted wing members each comprising a side portion extending in substantially perpendicular relation to an edge of said central portion, and an inwardly extending portion overlying said central portion and substantially parallel thereto, each inwardly extending portion terminating in a straight edge, said straight edges terminating in spaced opposed relation to each other to provide scraper blades adapted for the removal of mud from the golfer's shoes, said reverted wing portion extending from a longitudinal second portion, and terminating at a longitudinal point on said central portion spaced from said first end portion to provide auxiliary oppositely disposed scraping edges on the sides of said central body portion.
Vlchek, U.S. Pat. No. 1,195,297 describes a mortar joint scraper comprising a blade of plate material, scraper fingers projecting from the edges of the blade, and a handle supporting the blade whereby the blade takes a vertical position with relation to the face of a wall and the edges of the blade service as scrapers and guides.
Phillips, U.S. Pat. No. 3,820,185 describes a device for cleaning barbecue grills comprising a blade having a slot therein adapted to engage the grill rods. The blade is preferably twisted to facilitate pivoting the slot about the grill rods to clean the under surfaces thereof, and the blade may have two slots one an open slot at the tip thereof and one a closed slot set back from the tip, to enable cleaning of different sized grill rods. If the blade has two lots therein, the tip of the blade must be bent over just behind the scraping surface of the closed slot to permit engagement of the closed slot with the grill rods. In this case the closed slot is also preferably formed with an enlargement immediately behind the bend at the front of the slot, and the blade is preferably bent back near the opposite end of the closed slot.
Rastutis, U.S. Pat. No. 4,930,177 describes a scraping tool for removing paint residue from the friction seal of paint cans. The tool includes a handle of sufficient size to accommodate a human hand from which one of two scraping blades continue. Extending from the fore end of the tool is a rim scraping blade while conversely extending from the aft end is a lid scraping blade. The blades have contour edges shaped to approximate the cross sectional configuration of the rim and lid components of a paint can friction seal. The seal is cleaned completely, as the tool is designed to address both the rim and lid. Due to slightly smaller or larger blade dimensions, in respect to the seal configuration, the tool is allowed to move without encumbrance over the seal surface as it is cleaned. The blades are shaped to correspond specifically to the surfaces of the friction seal, permitting the tool to be used on assorted sizes of the cans as well as those of various manufacture.
Gruner, U.S. Pat. No. 5,638,570 describes a tool for scraping material from a bullnose installed on a corner joint of a drywall installation including an elongated device having a handle portion, a first end portion, a second end portion, and a size adapted for holding in one hand. The first end portion has a first convexly shaped edge that matches a concavely shaped portion of the bullnose. It enables a user to scrape the material from the bullnose by moving the convexly shaped edge along the concavely shaped portion of the bullnose. Preferably, the first concavely shaped edge is shaped in a 75-degree arc of 0.875 inch radius to match a convexly shaped portion of the bullnose when the bullnose is installed on a 90-degree corner joining, and the second end portion of the elongated device includes a second convexly shaped edge that is shaped in a 50-degree arc of 1.125 inch radius to match the concavely shaped portion of the bullnose when the bullnose is installed on a 135-degree corner joint. One embodiment takes the form of a 6.5 inch long aluminum bar having the specified shape.
Meier, PCT/EP97/02516 describes a tool for cleaning joints before they are filled with jointing compound, taking the form either of a plate-like handles or material-saving frames with at least one straight side from which projects a cleaning projection fitting into the joint to be cleaned, or as a handle section with interchangeable
