Abstract
A hoist includes an upper support plate connected to a lower guide plate by two sliding rods. The hoist is designed for lifting a plurality of elongated articles, such as projectiles, by hooking each article onto a fastener attached to the lower surface of the upper support plate with the article extending through one of several holes in the lower guide plate. The holes in the lower guide plate serve to keep the articles from banging together. Springs may be used to bias the upper support plate towards the lower guide plate. An associated method of using the hoist is especially well-suited for moving projectiles between pallets having different center-to-center or projectile separation distances.
Claims18
A hoist for lifting a plurality of like articles comprising:
- (a) an upper support plate having an upper surface and a lower surface,
- (b) a lower guide plate,
- (c) a first connector securing said lower guide plate to said upper support plate, said first connector allowing movement of said lower guide plate relative to said upper support plate in a direction normal to said lower guide plate,
- (d) a plurality of holes extending through said lower guide plate adapted to accommodate articles to be lifted, and
- (e) a plurality of fasteners mounted on the lower surface of said upper support plate, each fastener adapted to be secured to a catch on articles to be lifted,
- whereby each one of said fasteners may be secured to a catch on an article to be lifted such that the article is raised by the upper support plate by way of the fastener and the article extends through one of said holes in said lower guide plate.
A method of moving a plurality of vertically disposed like elongate articles, the steps comprising:
- (a) lowering a hoist having an upper support plate connected to a lower guide plate by at least two sliding rods fixed in a normal position to said lower guide plate, said sliding rods allowing movement of said lower guide plate relative to said upper support plate in a direction normal to said lower guide plate, said hoist being lowered until each of the elongate articles extends through one of a plurality of holes in said lower guide plate,
- (b) securing a plurality of fasteners mounted on a lower surface of said upper support plate to catches on the elongate articles, and
- (c) lifting the hoist such that the elongate articles are raised by the upper support plate by way of the fasteners with each of the elongate articles extending through one of said holes in said lower guide plate.
