摘要： A recoil starter casing is made from a plate. The plate has a polygonal top face and a plurality of rectangular side faces integral with and extending from respective edges of the top face. Each of the side faces includes a recess in its edge, and a pair of projections at opposite ends of the recess. A plurality of air inlets are formed in the side faces. The side faces are bent from the top face along the respective edges of the top face. A fan cover has slots. The projections are inserted into the corresponding slots. The free ends of the projections are then bent so as to secure the starter casing to the fan cover. The inside of the starter casing is cooled through the air inlets and the recesses or air vents.

摘要： A recoil starter is provided which prevents malfunction, such as disengagement of a claw, after the engine is started repeatedly even if the starter is not made of a material of high intensity. A spring can be wound substantially precisely circularly. It is quite easy to mount a friction plate to the starter. Furthermore, this subassembly does not loosen after long-term usage. A rope guide can be easily mounted to the starter case, thus reducing the fabrication cost. The recoil starter can be placed and locked in position relative to a fan cover with high accuracy. When the ratchet is in its protruded position, the pivotal point of the ratchet is located radially inside a pulley around the position where the pulley engages the ratchet. A ratchet support portion is formed radially outside the pulley on the reel. The ratchet forms a beam supported at its both ends. The beam acts against a force exerted by the pulley due to a resistance produced when the engine is started. A cover is mounted at the top end of the support portion to prevent the ratchet from moving toward the top end of the ratchet. A cylindrical engaging portion is formed on the outer surface of the stem of the starter case. One end of the spring engages this engaging portion. A rope takeout port is formed in the outer surface of the case such that the rope is payed out while tilted upwardly from a horizontal plane. The rope guide made of a hard material and acting to guide the rope is fitted over the case between the rope takeout port and the reel.

摘要： A rotary cutter head for use with a rotating filament trimmer in which a reel for winding cords or filaments is held between a housing covering a lower portion thereof and a retainer or hub fixed on the driven rotating shaft of the trimmer unit and is rotatably disposed within the housing. Within the bore of the reel, an axially movable slider is normally biased toward the retainer by the elastic force of a spring so that meshing engagement occurs between a peripheral array of axially projecting tongues formed on one end of the slider and a plurality of radial teeth-like ribs formed on the inner side of the retainer and establishes a driving connection to rotate the reels. By applying an axial impact against the housing, the slider is moved axially by inertial forces against the biasing force of the spring to release that engagement, and axially projecting detent fingers formed around the other end of the slider press against the opposed slopes of a circular rib formed on the inner side of the housing and bring about both positive relative rotation of the reel and fix a limit to such rotation to a predetermined amount thereby to play out a limited length of fresh cords. In order that the reel may rotate in an opposite direction to rewind the cords, moreover, the radial ribs formed on the retainer and the tongues of the slider are formed with opposed cooperating cam slopes which force the slider axially until the tongues are clear of the ribs during backward rotation.

摘要： There is provided a recoil starter for starting an internal combustion engine which has a simple and compact structure with a reduced number of parts and which can be manufactured at a reduced cost. In a recoil starter wherein a shaft portion 2' having a reel 3' rotatably attached thereto is provided on a starter case 1 and wherein a rope 4 wound around the reel 3' by a restoring force of a spring 5 is drawn out to rotate the reel 3' thereby driving a pulley 31 to start an internal combustion engine, a configuration is employed wherein a frictional resistance means is provided on the shaft portion 2'; one end of an arm 28 assembled with frictional resistance against the rotation of the reel 3' is anchored or press-fitted to the friction resistance means with another end thereof engaged with a guide groove 27 on the reel 3'; and the rotation of the reel 3' causes the other end of the arm 28 to move in the guide groove 27 for a swinging motion which causes the arm 28 to be engaged with a notch 32 on the pulley 31. This allows the number of parts to be reduced to achieve a reduced overall size and allows manufacturing cost to be reduced.

摘要： Apparatus for cutting foliage having a rotating head and an annular ring mounted for independent rotation in the head. A cam follower is pivotally mounted in the ring and is guided along a circumferential camming surface formed in the head. The camming surface has spaced apart lobes located adjacent to stops. The free end of a supply line is passed over the cam follower and passed out of the ring to a predetermined cutting length. When the head is rotating at operational speed, the resultant centrifugal force of the follower and the line will hold the follower against the stop. If the line is worn or damaged the holding force is decreased and the follower is released and guided over the stop thus allowing the ring to turn relative to the head until the next stop is encountered. This causes a given amount of line to be played out to replenish the damaged or worn section.

摘要： A recoil starter composed of: a rotating reel which fits loosely around a supporting shaft in a housing, a cylindrical hub portion of the reel having a spiral spline which is integrally formed on its inner periphery; a clutch cylinder which is loosely inserted into the cylindrical hub portion and carries a spline groove for such engagement with the hub spline whereby relative rotation of the reel hub and clutch cylinder causes axial projection and retraction of the clutch cylinder; and clutch projections which are provided at the free end of the clutch cylinder such as to project and engage recesses integral with a flywheel on the associated engine. Inside the clutch cylinder at its bottom a stepped portion is provided where an axial notch is formed. A coiled spring is loosely fitted around the supporting shaft, and compressed and frictionally restrained by a fixed washer against free rotation which frictional resistance is applied to the clutch cylinder either directly via a hooked end of the coiled spring loosely inserted into the notch inside the clutch cylinder or indirectly through a collar keyed to the notch. In order to prevent the clutch cylinder from projecting when the engine has started, the axial notch includes a lateral extension to resemble an L, the extension projecting peripherally with respect to the axial direction.
