Abstract: A generally cylindrical shaped tool handle holds multiple sizes of tools. The handle includes one or more holding slots each positioned on one of multiple outer surface faces into which tools are inserted and held. Each holding slot includes one or more contoured compartments in which tools rest when engaged with the handle. Each contoured compartment is of a size and dimension which corresponds to one or more tool sizes. In the preferred embodiment of the tool handle, three of its outer surface faces have a continuous holding slot with multiple receiving holes for inserting therein hexagonal wrenches of multiple sizes. The continuous holding slots of the preferred embodiment of the handle include multiple contoured compartments for holding an inserted hexagonal wrench. Each contoured compartment is formed about a corresponding receiving hole. A lock is positioned over the contoured compartment to irremovably confine the short leg of the hexagonal wrench within the contoured compartment.

Abstract: An improved hammer head structure with integral nail-starting feature. The nail-starting feature is accomplished by a nail head seat horizontally forged, bored or otherwise machined into the neck of the hammer head parallel to and beneath the poll. The nail head seat is formed with a conical-taper to accommodate a range of nail types/sizes, and to eliminate sliding and prevent shifting of the nail head despite a downwardly-arcing drive. In addition, a nail-holding device is inserted upwardly into the poll of the hammer head, and this extends either a clip or magnet downward beneath the poll to support the length of the nail. The nail-holding device is flanked by two opposing lobes which provide a deeply grooved nail shaft guide for further support and protection of the nail. The length of the nail is supported by a clip or magnetic nail-holding insert that is set into a borehole running upward into the poll of the hammer.
Abstract: A claw hammer head having a body, a neck extending from the front of the body and having a face, and a claw extending from the back of the body. The claw is a multi-radius claw having a profile which maximizes hand-pull leverage during the entire scope of a nail pull rotation. The head has a high raised brow. The claw tips are tapered and pointed, enabling the claw to dig under nail heads that are below the wood surface. The claw has a very sharp V slot near the end of the claw. The head is provided with a cup in the pocket which is used to hold a nail head when one handed spiking with a nail positioned with the head of the nail in the cup and a shank in the slot captured by the V shape of the slot. The neck is a long reach neck with a progressive radius and the face is oversized and slightly contoured to about equal to a 6″ R. The edge of the face is chamfered. The head is provided with large side hitting faces on each side of the body.
Abstract: A dimpler tool comprises a handle member having a side wall, a closed bottom, and an open top defining an interior space. The dimpler tool further includes a lid threadably coupled to the handle member so as to removably cover the open top. A first portion of a shaft is embedded in the closed bottom of the handle member and a second portion of the shaft projects from the bottom and is normal thereto. A dimpler attachment is removably coupled to the second portion of the shaft and includes a tip that tapers to a point. The tip may be inserted into a hole left in a wall as a result of removal of a fastener, the hole being smoothed over by a rotational pressure applied to the dimpler tool by a user. The dimpler attachment is interchangeable with attachments having variously sized tips or with auxiliary attachments having variously configured screwdriver tips.
Abstract: A fastener driving assembly or tool includes a metal handle having opposite ends with an elongated driver shaft projecting from one end and a swivel knob installed on the other end. An electrical insulator is installed between the handle and the driver shaft and an insulating filler secures the shaft, insulator and handle together. The handle includes a recess for storing a lever arm or breaking bar adapted to outwardly pivot with respect to the longitudinal axis of the handle and driver shaft. A pivot rotatably connects one end of the lever arm with the handle.
Abstract: A noncircular-based undulating key-receiving configuration, opposed undulating side walls in said configuration, a centerline within said side walls, with the centerline of the configuration lying within inner and outer noncircular perimeters. A key-receiving configuration containing a first undulating configuration within a second undulating configuration. A key having a first body insertable within a second body with both bodies having undulating key configurations thereon. A key-receiving groove having chamfered edges.
Abstract: A set of firefighting tools for use in fighting forest fires and the like in different types of terrain and vegetation. An elongate handle is equipped with a releasably latching connector, and several different tool heads are attachable to the handle to perform various functions. One head has a pivotably attached shovel blade and is useful as a shovel, as a scraper or as a rake, when held in respective positions by a latching mechanism. Another tool head has a lightweight central body and replaceable oppositely directed axe and grub hoe blade portions. Yet a further tool head includes a resiliently flexible outer portion to which are fastened several flexible straps for beating out fires. Each head includes a socket adapted for emergency attachment to a simple wooden handle portion.
Abstract: A screw driver exclusively applied to drive a particular screw having compound drive recesses that can be driven by various conventional drivers, i.e., slot, cross, square-cross, square, and double-cross. The screw driver enables its drive bit to supply sufficiently large driving torques to the compound drive recesses of the screw and the screw driver lodges securely within the compound drive recesses of the screw as the drive bit of the driver turns.
Abstract: A mobile automatic machine for fastening fasteners which includes a rod mounted on wheels (11) and is attachable to and held in contact with a workpiece by a vacuum in suction cups (3) is disclosed. The fasteners are blown from a fastener feeder (14) through hoses (15) to a fastener driver (20) which includes a fastener holder (6). The fastener driver engages fasteners held by the fastener holder (6) and drives them into the workpiece under the control of a controller. The fastener driver (20) is slidably mounted on the rod and moves linearly at repeatable intervals or at a uniform speed along the entire length of rod (1) under the control of a controller. Other tools, such as drills or milling devices can substituted for the fastener driver.
Abstract: A method and apparatus for removing a closure from a center-fill drum opening.

Abstract: Described is a wrench comprising a base plate having a generally circular periphery. A plurality of teeth extend radially from the periphery of the base plate and are adapted to engage the indentations in the top of a compression ring of a base assembly. The base plate has a shaft extending upwardly therefrom. Preferably, the shaft includes a handle portion which an installer may use to apply torque to the tool and, thereby, to the compression ring. The shaft may, however, be adapted for engagement with another tool, such as a pipe wrench or electric drill.
Abstract: An open end wrench having two heads each of which provides ratchet action, each of which accepts fasteners of different nominal sizes, and each of which imposes torque on the fastener only on flat facets and not at apices between adjacent facets. Each head has a first jaw bearing a convex interior surface facing the interior surface of a second jaw. The second jaw has plural pairs of intersecting facets where, in a first embodiment, the included angle formed between intersecting facets is greater than ninety degrees and less than one hundred twenty degrees. In another embodiment, the included angle is greater than seventy degrees and less than ninety degrees. Each pair of intersecting facets accommodates a polygonal fastener of one nominal size. The two embodiments are usable with hexagonal and square headed fasteners, respectively.
