414434000 | MOTION OR DRAFT RESPONSIVE LOAD HANDLER AND TRANSPORTER | 6 |
414437000 | Ground engageable means | 6 |
20090274541 | Safety cone placing device and method - Automatic placement of safety cones from a moving vehicle is provided. The preferred safety cone would have a flexible cone part. A receptacle holds a plurality of safety cones either with the flexible cone part in non-compressed position or in spring-loaded position. The receptacle is removably attached to the vehicle. A releasing means that is attached to the receptacle is controlled and advances the safety cones in an automatic and controlled fashion, one-by-one, to different locations on a ground surface from a moving vehicle. The advantage is that it automatically handles the placement of a plurality of safety cones while driving. There would be no more need for a person to manually place the safety cones. It provides for increased road safety since it decreases or even eliminates the number of fatal or non-fatal accidents as well as chronic injuries of road-workers that are involved in placing safety cones. | 11-05-2009 |

20130064631 | TENNIS BALL COLLECTION DEVICE - A tennis ball collection device includes a rotating drum that rotates at a higher speed than the rotation of the wheels that carry the device. Additionally, the drum rail that operates in connection with the rotating drum to lift a ball off of a ground is allowed to move in the horizontal direction. This back and forth movement is facilitated by a spring that otherwise biases the drum rail forward to a rest position. | 03-14-2013 |
20150093224 | TENNIS BALL COLLECTION DEVICE - A tennis ball collection device includes a rotating drum that rotates at a higher speed than the rotation of the wheels that carry the device. Additionally, the drum rail that operates in connection with the rotating drum to lift a ball off of a ground is allowed to move in the horizontal direction. This back and forth movement is facilitated by a spring that otherwise biases the drum rail forward to a rest position. | 04-02-2015 |

20130266410 | PINE CONE COLLECTION DEVICE - A rolling collection tool allows for retrieval of ground objects including pine cones by a user while standing erect. A method for construction of the device is provided in which a plurality of wires are formed into a generally oval shaped chamber and covered in a flexible covering in sets of two or more wires. The chamber is connected to a bail and handle and rolls to pick up and store objects in the chamber until emptied. The objects enter the chamber as the device rolls by temporary separation of the covered wires for the object, and the device retains the objects by resilient return movement of the covered wires to their original position. The flexible covering on the wires rotates around sets of the wires as the device retrieves objects. | 10-10-2013 |
20140161574 | Nut Gatherer and Method of Constructing Same - A nut gatherer device includes a cage formed by a plurality of wires. Each of the wires has a bowed middle segment and two straight end portions. Opposite end portions of the wires are secured within opposed hubs, each hub including first and second annular sets of spaced teeth, with the end portions of the wires secured in the radially-aligned spaces. A retainer affixed to the hub secures the wires between. A compressible washer between the wires and the retainer provides further securement and vibration dampening. An axle aperture in the hubs allows the cage to be rotatably attached to a handle. In use, the wire cage is rolled on the ground into contact with a bulky object, such as a nut, so that the object forces the wires to separate and permit the nut to pass into the cage where it is retained until emptying. | 06-12-2014 |

20080206029 | Trailer support apparatus and method - An apparatus includes a trailer support, and a lift mechanism attached to the trailer support. The apparatus also includes a first drive unit attached to the trailer support, and a second drive unit attached to the trailer support. The first drive unit steers the trailer support. The second drive unit moves the jack. | 08-28-2008 |
