Brace Or Prop To Support Tilted Load Body Patents (Class 298/17B)
  • Patent number: 6036275
    Abstract: An attachment mounting structure is provided for cargo bed and sprayer assembly attachments usable on a utility vehicle adapted for use in turf related applications. The structure includes pivotable supports between each attachment and the vehicle frame that permit them to be interchangeably mounted on the vehicle. The structure further includes a connection on each attachment that permits it to be secured to a hydraulic cylinder carried by the vehicle, thereby allowing the attachment to be tilted upward and rearwardly so as to provide access to the engine and/or related drive components carried beneath the attachment. The mounting structure also permits the two attachments to be quickly and easily interchanged so that the vehicle could be better utilized.

  • Patent number: 4836610
    Abstract: A collector cart includes a body having an open rear end, which is closed by a canopy pivotally mounted adjacent its front end on the body adjacent its front end. The body has a support pivotally connected to caster wheel supports and a tow bar attached to a riding lawn mower hitch bar. Telescoping chutes connect the mower outlet with a canopy port to fill the cart with debris. When the cart is to be dumped, a linkage mechanism is activated by an operator, who remains on the mower, raising a lift handle to initially cause rearward shifting of the canopy relative to the body to release a locking connection of the rear of the canopy to the rear of the body. The body is released from its tow bar at the same time so that continued raising of the lift handle by the operator causes the body to pivot to a dumping position while the canopy pivots away from the body due to a rope of a fixed length connecting the front of the canopy to the mower.

    Abstract: Tractor front loaders have sometimes been provided with struts enabling them to be locked in raised position. These struts have had to be moved bodily between operative and inoperative positions. To avoid the need for bodily movement, the struts are made telescopic and are pivotable on loader support frames fixed to opposite sides of the tractor. Loader booms, and the rams of ram-and-cylinder assemblies for pivoting the booms, are pivotable on the support frames in known manner. The struts comprise inner and outer channel sections and are pivotable between retracted inoperative positions in which they are secured to the support frames and extended operative positions in which they are secured in contact with the adjacent ends of the cylinders of the extended assemblies.

  • Patent number: 4388038
    Abstract: An automatic locking pin retraction mechanism for a skid-steer loader is disclosed wherein the locking pins for locking the loader boom arms in an elevated position will be automatically retracted under conditions where the locking pins are extended into the path of movement of the boom arms and the boom arms are below the locking pins and moving upwardly toward engagement with the locking pins, so as to avoid engagement between the boom arms and the locking pins. The retraction mechanism includes a pivotally mounted first member engageable with one of the boom arms and a link interconnecting the first member and a mechanism for simultaneously actuating the locking pins. Pivotal movement of the first member caused by engagement with the boom arm effects a retraction of the locking pins before the boom arms can engage therewith. An over-center spring arrangement is provided to bias the first member in the engagement position or in a neutral position, depending on the position of the first member.

The wedge comprises a main body in which are rotatably mounted a pair of driven rollers designed for riding on the frame of the truck and allowing translation of the body along the frame, and a driving roller designed for riding on the frame of the dumping platform. The driving roller which forms part of the wedge, positively engages the driven rollers and rotates them in the opposite direction towards the junction between the frame of the truck and the frame of the platform when the dumping platform is moving down, thus causing movement of the wedge towards said junction and self-blocking of the platform in dumping position. This wedge which automatically blocks up to the platform of a truck in dumping position in the case of failure of the hydraulic mechanism used for rising up the platform, can advantageously be used as safety device by a mechanic who has to work under the platform of a dumping truck.

The brace includes a support column, one end of which is pivotally connected to a body longsill and the other end is retained by a release mechanism located on the body for holding the column in riding position. Provided on the chassis is a retainer for securely retaining the column when it extends between the body (when raised) and chassis as a brace to prevent the body from falling. A stop is provided for limiting the pivot angle of the column. The brace is installed in supporting position without an operator having to locate any portion of his body under the truck body while raised. This is accomplished by actuating the release mechanism to release the column. The body is then raised from remote control location and the column pivots until it abuts its stop mechanism which locates the lower end of the column above the retainer on the chassis.
