Patent number: 7797836Abstract: A compact utility knife includes a blade holder slidably connected to a handle. A trapezoidal utility blade detachably mounts to the blade holder via a blade lock mechanism. A slide lock mechanism selectively retains the blade holder in its extended or retracted position relative to the handle. When the blade holder is extended, the blade holder and a majority of the blade extend forwardly of a forwardmost point of the handle. Extending the blade holder significantly increases an overall length of the knife such that the knife is comfortable to use when in the extended position and longitudinally compact when in the retracted position. The knife includes a blade lock mechanism. An aperture in the front of the handle creates a gap between the blade and the handle to discourage debris on the blade from transferring to the handle when the blade is retracted.Type: GrantFiled: August 2, 2005Date of Patent: September 21, 2010Assignee: The Stanley WorksInventors: Eric Ranieri, Stephen Rowlay, Gary E Van Deursen

Patent number: 7797839Abstract: A trimmer head for a rotary line trimmer including a housing operatively connected to the trimmer and a spool for carrying cutting line thereon. The spool is operatively connected to the housing for rotation therewith and defines a line receptor channel having opposed open ends and traversing the spool. The channel is formed by line guide inserts held within the spool body preferably utilizing the shrinkage of the molded spool material about the inserts. The channel can be aligned with the eyelets in the housing skirt such that cutting line can be inserted therethrough and wrapped about the spool upon relative rotation of the spool and housing without having to interrupt the operative connection therebetween. A central portion of the channel is exposed to provide access to the line so that the line can be pulled from the head without having to interrupt the operative connection therebetween.Type: GrantFiled: February 15, 2008Date of Patent: September 21, 2010Assignee: Proulx Manufacturing, Inc.Inventor: Richard A.
