Abstract: The nail driving tool magazine (10) includes a substantially elongate main body (12) adapted to be selectively attached to a nail driving tool (T). The main body includes at least two nail feed rails (14, 16) open at one end for loading the nails (N). The opposite end is connected to a feed chute (22) directing nails to a nailing chamber (21). Guide tracks (35, 36, 45, 46) are disposed adjacent each feed rail. A spring-loaded feed carriage (30, 40) rides in each guide track to advance the nails. A freely pivoting rail selector (24) is disposed in the feed chute to automatically switch to a full rail when the other rail is spent to selectively direct the nails to the nail driving chamber. In this position, the rail selector blocks the spent rail so that it may be reloaded.

Abstract: The powered adjustable pipe wrench has a motorized rotary grip to rotate a pipe component clamped therein and a laterally spaced stationary grip to hold a second pipe component stationary relative to the first as it is being rotated. The pipe wrench may have a cylindrical jaw housing with semicylindrical fixed and openable portions hinged to one another. One end of the housing includes a powered component to rotate the pipe component held therein, while the other housing end includes jaw components holding the second pipe component stationary. Alternatively, the pipe wrench may have a powered component extending from the jaw of the wrench body to rotate the first pipe component, and a rectilinearly adjustable jaw portion extending from the wrench body. A set of jaw components is axially spaced from the rotary component to hold the second pipe component stationary.

Abstract: A powered stapler (10) and method of operating same for stapling together two or more metal workpieces. The powered stapler (10) includes a main frame member (20) adapted to carry a strip of staples. The frame member has an anvil (20e) covered by a front nosepiece (48) at one end. A lower jaw member (22), having a lower cam slot (34), is pivotally attached to the main frame member. The lower jaw member (22) has a forming die (56). An upper ram member (24) has an upper cam slot (32) and a staple-driving hammer (52). The upper ram member (24) is pivotally attached to the lower jaw member (22). A drive rod (28) extends from a power unit (12) and has a cam bar (30) at one end protruding through the upper cam slot (32) in the upper ram member (24) and through the lower cam slot (34).

Abstract: Adjustable, torque compensating powered pipe wrench for the tightening and loosening of threaded pipe onto threaded pipe fittings. A portable wrench with size adjustable non-rotating grippers and size adjustable rotating grippers powered by a drive motor allows for the powered tightening and loosening of threaded pipe onto threaded pipe fittings.

Abstract: Combination light fixture/HVAC duct/ad card holder for transit vehicle has roof mounted light fixture having a housing extending inboard to receive roof fasteners readily accessible through a cover strip. A single panel provides ad display serves as air duct with air vents and is supported by a detachable hinge at the light housing. In another embodiment the lamp housing is below the card panel. Combination outboard extrusions form a wiring trough and attachment for duct lower wall, and inboard extrusions form detachable hinge, supporting display panel and card holder. Upper bracket extrusion receives panel and card. Extrusions are attached to display panel by double-sided adhesive tape. Light fixture has ballast member accessible from inside lamp housing.

Abstract: Overhead parcel rack and HVAC duct for public transportation vehicles such as buses and trains. Modular overhead parcel rack includes inboard and outboard vertical and bottom horizontal surfaces formed from composite material panels. Modular HVAC duct includes bottom horizontal and inboard vertical surfaces with attachment of overhead parcel rack to HVAC duct vertical surface. Longitudinally extending rail member attaches to inboard vertical surfaces of modular overhead parcel rack sections and is suspended from vehicle ceiling by means of formed hanger brackets. Modular sections of parcel rack and modular sections of duct are joined together by notched and formed unequal-length longitudinal strips.

Abstract: A combination light fixture/HVAC duct/advertising card holder for public transportation vehicles such as buses and trains. The light fixture includes a lens having a transparent bottom portion and ribbed side portions for directing light downward towards the passengers and diffusing light sideways towards the windows and driver. The advertising panel forms part of the HVAC duct, with the vehicle side and roof forming the remainder. The advertising panel and light fixture are pivotally secured by a detachable hinge allowing them to either pivot downwards or be completely detached. The HVAC duct and advertising panel may further include other light fixtures, ventilation openings, speakers, or other comfort aids.
