  • Patent number: 9295187
    Abstract: The dual blade garden hoe device includes an elongated handle having a shaft mounted at the working end thereof. A pair of blades is secured onto the shaft and disposed at a variable pitch. The blades can be positioned at various locations along the length of the shaft to create different widths between the blades. The blades comprise a cutting portion that create a pair of parallel troughs when dragged through soil. When the blades are in contact with the ground, each blade creates a separate and parallel trough, thereby reducing the time and effort needed to make a systematic gardens design or a plurality of farming rows. Additionally, the blades can move in a back and forth motion, depending upon the direction of travel, and laterally depending on obstructions in the soil.

  • Patent number: 8918998
    Abstract: A hedge trimmer having a rear handle, a tubular handle and a blade arrangement with at least one cutter bar disposed in a cutter bar plane. An internal combustion engine drives the cutter bars in a reciprocating manner, and has a combustion chamber and a crankshaft mounted in a crankcase so as to be rotatable about an axis of rotation. The combustion chamber faces the rear handle, and the crankcase faces the blade arrangement. The blade arrangement has a longitudinal central axis, and the hedge trimmer has a longitudinal plane that is disposed parallel to the axis of rotation of the crankshaft and transverse to the cutter bar plane. The longitudinal central axis of the blade arrangement lies in the longitudinal plane of the hedge trimmer.

  • Patent number: 8713803
    Abstract: A blade assembly of a hedge trimmer includes at least one cutting blade having cutting teeth. At least one portion of the cutting teeth are configured as protective teeth which, referred to the cutting blade axis, have an inner cutting region and from which an outer protective finger extends. The protective tooth is, referred to its tooth axis, configured unsymmetrically. The protective tooth has a cutting side and an opposite-lying holding side and a cutting edge in the cutting region on the cutting side and a holding edge on the holding side. The protective finger has a forward edge on the cutting side and a rearward edge on the holding side. Starting from the blade axis, the forward edge is inclined to the tooth axis and the rearward edge, starting from the blade axis, is inclined away from the tooth axis.

  • Patent number: 8713802
    Abstract: A hair-clipper includes a stationary blade and a movable blade. The comb projections of the stationary blade include a skin-contact surface which abuts against skin, and a slide surface with which the comb projections of the movable blade come into slide contact. Further, the main body of the stationary blade includes an opposed surface which is opposed to a plane including the skin-contact surface, and a shortest distance between the opposed surface and the plane including the skin-contact surface is equal to or greater than a distance between the plane including the skin-contact surface and the comb projection of the movable blade.

  • Patent number: 8549756
    Abstract: A vibrator motor in a hair clipper has a stationary piece and a moving piece. The stationary piece has a primary leg and at least one secondary leg. The primary leg fits through an opening in a coil. A flange is then press fit onto the leg so that the coil is captured on the primary leg. The flange provides a magnetic pole face that is larger than the opening in the coil, which increases the efficiency of the motor. The flange is press fit in a single operation by pressing a primary prong into a primary socket, and pressing two secondary prongs into secondary sockets. The secondary prongs are guided inwardly as they enter the secondary sockets, which closes the primary socket around the primary prong. A drive arm is secured to an arm of the moving piece. The arm is angled in relation to the drive arm to put even pressure on the moving blade in the hair clipper.

  • Patent number: 8397389
    Abstract: A power tool has a drive motor and first and second tool members driven reciprocatingly by the drive motor in opposite directions, respectively. The first tool member is driven by a first connecting rod and the first connecting rod is connected to the first tool member by a first pivot joint arranged on the first connecting rod. The second tool member is driven by a second connecting rod and the second connecting rod is connected to the second tool member by a second pivot joint arranged on the second connecting rod. The first pivot joint is arranged on an end of the first connecting rod which end is facing the tool members. The second pivot joint is arranged on an end of the second connecting rod which end is facing away from the tool members.

  • Patent number: 8341846
    Abstract: The hair clippers use a self-contained motor-driven adjustment mechanism to adjust the relative position of the stationary and reciprocating blades of a common type of blade set. Two momentary switches operable by the thumb of the hand holding the clipper afford a barber total automatic adjustment with the clipper itself in an on or off condition. Since the small gear motors used for the adjustment are brush type or brushless permanent magnet motors which are operated by direct current, the adjustment feature is most compatible with cordless clippers already using an on-board DC source in the form of a re-chargeable battery to drive the reciprocating blade. The invention will be described as a modification of a cordless clipper, although AC driven corded type clippers can also be modified with this feature by the addition of an on-board AC to DC power supply for the adjustment motor.

  • Patent number: 7340839
    Abstract: Disclosed is a hair clipper having a moving lower blade, in which the lower blade moves so that upper and lower blades reciprocate in opposite directions and cross each other. In the hair clipper, an eccentric cam is connected to a rotary shaft of a motor installed in a main body, and an eccentric shaft formed on the eccentric cam is inserted into a fixing groove formed in an upper blade fixing plate and vibrates horizontally, the lower blade is mounted on a blade support, such that the lower blade can move horizontally, and is fixed to one end of a link, the central portion of which is fixed to the blade support, and the other end of which is fixed to the lower surface of an upper blade fixing plate, to which an upper blade is fixed, and thus, when the upper blade fixing plate vibrates horizontally by the rotation of the motor, the lower blade vibrates on the blade support by the link in the direction opposite to the vibration of the upper blade.

  • Patent number: 5259116
    Abstract: The hair grooming clipper is driven by an improved eccentric coupling to a motor housed in the handle. The motor is incorporated in the clipper casing and utilizes an improved eccentric coupling that results in more power to the clipper head and less wear in the coupling. The improved design delivers more power to the clipper head, generating less heat.
