    Abstract: An escape implement assists a firefighter in exiting a burning building through a window by securing an elongate bar extending longitudinally and juxtaposed with a corner of the window. The bar is secured in place with sharp-ended members projecting from the bar in the same lateral directions for piercing the wall to anchor the bar to the wall so as to span the corner, with an intermediate portion of the bar placed relative to the corner for enabling the attachment of an escape line to the intermediate portion of the bar. The escape line is attached to a looped member coupled with the bar for swiveling about the longitudinal direction so as to avoid the transmission of torque from the escape line to the bar which otherwise could tend to dislodge the sharp-ended members from the wall.

  • Patent number: 7062809
    Abstract: A roofing hatchet having a magnetic striking face is hereby disclosed. A unique shouldered cap housing the magnet dampens the forces transferred from the striking by transferring the force directly to the hatchet head, bypassing the magnet, thereby preventing demagnetization typically caused by such repeated linear forces. Additional features include a cutting blade housing adapted to adjustably receive a variety of different commercially available utility knife blades, an adjustable gauge for gauging a distance from the bitted end of the hatchet, and a pulling notch for pulling fasteners from a surface. Unlike prior art hatchets, the handle of the inventive hatchet is angled, relative to the striking face, such that the force transfer from the hand of a user to a fastener being driven into a sloping surface is optimized.

    Abstract: The HUMPHREYS FIRE-RESCUE TOOL is a multi-purpose, adjustable length combination tool which provides the fire-rescue worker the ability to perform a wide variety of tasks. The tool may be separated into two tools by removing the pry bar from the handle of the maul. This permits the user to drive the pry bar with the hammer into the material to be pried. The hammer can then be replaced on the pry bar to increase leverage for prying. This tool will supplement and often eliminate the need to carry bulky tools such as the axe, hammer, pry tools, short pike pole, gas wrench, chisel, and Glass Master. The firefighter can carry this 6.5-pound tool on his belt by means of an integral belt clip. This leaves both hands free to perform other tasks such as pulling a hoseline, yet the tool is available when it is needed. No other fire tool is as versatile or convenient to use.

  • Patent number: 5481950
    Abstract: A rigid head extending laterally from an adjustable handle has an elongate slot therethrough aligned with the longitudinal axis, of the handle for receiving and operating the handle of a valve. A first concave surface is formed in the upper edge of the head for pushing on the spokes of a brake wheel. The first concave surface has opposite ends of similar slope approaching ninety degrees relative to the upper edge for pushing on the spokes of a brake wheel and preventing kick-out of the tool from the brake wheel. A second concave surface is formed in the lower edge of the head for pulling on the spokes of a brake wheel. A first end of the second concave surface has a slope approaching ninety degrees relative to the lower edge. An opposite end of the second concave surface adjacent the outer edge of the head has a slope relative to the lower edge of the head which is significantly less than the slope of the first end to facilitate kick-out of the tool while the brake wheel is in motion.

  • Patent number: 5425176
    Abstract: An ice axe device comprising a handle having a gripping end and a working end and an impact member attached at the working end. The gripping end is configured about its longitudinal axis with a smaller, forward curvature and a larger, rearward curvature. The smaller, forward curvature is approximately defined by a radius slightly smaller than a corresponding radius of an arc formed at an inner surface of the user's fingers when wrapped about that portion of the gripping end. The larger, rearward curvature is approximately defined by a larger radius which is slightly smaller than a corresponding radius of an arc formed by a users palm and a proximate inside portion of an extending thumb when wrapped around the gripping end.

  • Patent number: 5297306
    Abstract: An ax has an elongated socket extending along the top of the ax head in parallel relationship with the top of the ax blade. A detachable implement, which may be a spade blade, a pick point, a saw blade or any of various other implements, has a tang which is fitted into the socket to fasten the implement to the ax head. A spring biased latch pin, disposed in a passage in the ax head, has a first end that extends into an opening in the implement tang and an opposite end that protrudes from the the base of the ax head to enable retraction of the pin and replacement of the implement with a different implement. The socket is preferably open at both ends with the latch pin being midway between the ends enabling entry of an implement tang from either of two opposite directions to accommodate to reversible implements such as a combination hoe and rake blade.

  • Patent number: 4958395
    Abstract: A cutting tool kit for outdoorsman consisting of a knife, a saw, a hatchet, and an ax. Four handles including two head handles releasably secured to the coupling hub openings in the ax and hatchet having tubular ends adapted to telescope onto the head handles and to a corresponding shaft on the saw. The hubs and head handles have coupling tapered keyways and keys which taper outwardly from the inner end of the hub to the outer end such that the ax coupling forces increase as the ax tends to move from the handle. The handles have slightly different lengths to form different operations. The grip handles have radial pin openings for coupling to spring-loaded pins in the head handles and shaft. A flat carrying case includes individual pockets for storage of the separate parts of the assembly.

  • Patent number: 4825918
    Abstract: The present disclosure is directed to a log splitting sledge. The sledge has a cutting blade projecting from a lower face of the head of the sledge. One face of the blade is integral with a side face of the head and extends at an angle of about 12 degrees of the handle. The angle is a result of either a bend in the handle or the handle being mounted in the head at a non 90 degree angle. The sledge is first used to drive one or more wedges in a log, partially splitting the log. The head of the sledge is then forced down into the partially split log, the log standing on end and the handle protruding upwardly. Then the sledge handle is moved through an arc having the blade edge as a pivot line to complete the splitting of the log. If any slivers are holding the split portions together, the sledge can be then used as a vertical axe with the front cutting edge slicing through the slivers.

  • Patent number: 4727609
    Abstract: A survival tool having a multi-function tool head secured to an elongated hollow shaft. The tool head includes a shovel blade portion with a marginal edge terminating at a rectilinear shoulder portion that is attached to the hollow shaft. An axe blade is formed in one piece with the shovel blade so as to be substantially coextensive with the shoulder portion of the shovel. The cutting edge of the axe blade is substantially continuous with the portion of the marginal edge of this shovel adjacent the shoulder portion. A hammer is formed in one piece with the shovel and axe that has a striking face extending outwardly from the shovel blade adjacent the shoulder portion thereof opposite the cutting edge of the axe. The hollow shaft includes a transverse slot adjacent the tool head which is sized to slidably receive a one-piece bow. An adjustable pressure plate within the hollow shaft engages the central portion of the bow to secure the bow in place.
