  • Patent number: 4867626
    Abstract: The invention relates to apparatus for collating and stacking building components, such as roof tiles. The apparatus comprises pairs of shelves for receiving and supporting tiles which are fed into the shelves continuously by means of a conveyor arrangement. The shelves are moved downwards towards a stack support positioned beneath the shelves. As a pair of shelves becomes the lowermost pair, the two shelves move apart releasing the tile carried thereon onto the stack support to form part of a stack. When the stack is complete, the stack support is removed and the number of shelves between the uppermost and lowermost shelf increased to enable a predetermined number of tiles to be stored in the shelves while the stack support is being replaced.

  • 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.

  • Patent number: 4836731
    Abstract: A method and apparatus for cubing paving stones or similar stones which are not adapted to forming a self-supporting unit through the means of pressure applied to opposite sides of a tier of such stones. In the present invention, the stones on a flat pallet are contacted with side pressure to bring the stones into a compact unit on the pallet. While the stones are so clamped, the pallet is clamped along its opposite side edges and transported, with the tier of stones thereon, to a location above a previously deposited tier of such stones or a pallet. When so positioned, the pallet is withdrawn from its supporting position beneath the stones and the stones settle gently onto the previously laid tier or pallet. The force applied to the stones on the pallet is chosen to be less than the force that would be required to urge the stones against one another to form a self-supporting unit.

  • Patent number: 4832558
    Abstract: Presented is an apparatus for handling flat panes of plate glass. After manufacture, flat panes of glass are stored in large warehouses prior to distribution to glass distributors and wholesalers. Flat panes of glass are stored standing on edge, with multiple panes making up a "block" in which the individual panes are in close abutting relation to each other. "Blocks" of glass are supported on wood stringers lying flat on a concrete floor, and wood spacer members separate one "block" from the next adjacent "block." The apparatus of this invention includes a steel frame the lower edge of which is provided with adjustable "feet" that project under a "block" of glass and which can separate one or more panes from the "block." After elevating the selected and separated panes of glass above the remaining "block", telescoping fingers mounted on the upper edge of the frame move into position behind the separated panes to retain the separated panes on the frame for movement to a desired location.
