  • Patent number: 4429515
    Abstract: The invention comprises an improved lawn mowing machine with a forward mounted mower deck including a plurality of rotary cutters. The blades or cutters rotate in opposite direction on opposite sides of the deck to bring the grass clippings to a deck mounted central vacuum. The mower blades are driven by a belt drive to eliminate expensive drive shafts and gearboxes. Applicant's 45.degree. twist belt drive geometry provides increased life to the belt over prior art 90.degree. twist belt drive geometries.The mower deck includes novel side mower wings. A combined clutch and brake mechanism disengages the drive belt to the wing blade spindle and simultaneously brings the blade to a stop within one second when the wing is raised beyond its cutting range. The wing deck is attached to the mower central deck by a depressed hinge substantially close to the elevation of the mower blades.

  • Patent number: 4428184
    Abstract: A rotary lawn mower blade mounted on a blade carrier by diametrically spaced bolts is further retained against release from the drive shaft by a retainer fixed on the drive shaft and having a shank extending through a central opening in the blade and having an enlarged head to obstruct separation of the blade from the retainer. Preferably, the blade opening is larger than the shank and the retainer head is in the form of a transverse bar, narrower than such opening, so that the blade can be removed by manipulation in one direction to an eccentric position, then tilted to disengage it from one end of the bar, and then moved in the opposite direction to disengage it from the other end of the bar.

  • Patent number: 4426957
    Abstract: A safety-release pet collar to prevent animals from possibly choking in the event that the collar inadvertently becomes caught on a branch, twig, stump, fence post or the like. The collar comprises a two-piece band intended to encircle a pet's neck in the usual manner and to be fastened by a conventional buckle arrangement. The band has a second pair of separable ends which are held together by a releasable connector, such as cooperable loop and hook strips. The second pair of ends have loops through which a leash or clasp can be passed, to lock the ends together and prevent separation of the connector strips. When the pet is on the leash, strain on the connector strips is relieved and the pet cannot normally pull the connection loose. However, when the leash or clasp is removed and the collar remains in place, the Velcro connector strips can separate under force if it inadvertently becomes caught on or entangled in branches, etc.

  • Patent number: 4426827
    Abstract: A mowing implement essentially comprising a housing extending transversely of the direction of movement of the mowing implement, a plurality of mowing members rotatably journalled on said housing and a drive assembly arranged within said housing for driving the mowing members and formed by a sequence of gears including both driving gears connected with the moving members and at least four coupling gears drivingly interconnecting each adjacent pair of driving gears. All of the gears are small and are arranged in line so that the housing is narrow. The housing is made very rigid by fixedly interconnecting the top and bottom walls together by structure which supports the bearings for the coupling gears. The assembly is economical so that it can be replaced as a unit rather than being repaired.

  • Patent number: 4421058
    Abstract: This invention is concerned with devices for controlling movement of small animals, of the kind commonly known as "Cat Ports". The device is activated by an operating magnet worn by the small animal, which when the animal moves to pass through the device, closes a reed switch. The reed switch is adjustably pre-biased by a positionally adjustable permanent magnet, to afford the reed switch with a desired sensitivity, and a control circuit includes a re-setting coil to return the reed switch to its open position after a predetermined time interval. The device may readily be modified to control movement of animals in either, or both directions, to and from a designated area.

  • Patent number: 4419856
    Abstract: Apparatus is disclosed for harvesting a crop of the character having stalks which carry seed pods, such as the sesame plant. The apparatus includes a harvesting vehicle which mounts at its front end a header structure. The header structure includes side-by-side guide units adapted for movement along individual rows of the stalks. Each guide unit includes a pair of forwardly diverging guide members which gently guide the stalks for relative movement toward rotary cutter units disposed generally at the apex of the guide members. Horizontally extending, spaced-apart stabilizer fingers are mounted for movement along each guide unit in a path toward the cutter units for stabilizing the stalks prior to and during the time that they are cut off. Drive means is provided for controlling rearward movement of the fingers at a rate substantially equal to the rate of forward vehicle travel whereby the fingers maintain registry with the stalks up to the point at which they are cut off.
