  • Publication number: 20080047473
    Abstract: A pallet is created from two sets of thin stringers crossing and mated orthogonally, forming forkway notches and including ribs to guide the fingers of lifting machinery through the pallet. The pallet may include an optional mortised deck.

  • Patent number: 4841880
    Abstract: A pallet is constructed of two parallel lower beams on edge and four parallel upper beams on edge crossing the lower beams and connected to the lower beams by notched joints which provide clearance for the fork of a forklift beneath the upper beams at two sides of the pallet, and above the upper edges of the lower beams and below the upper edges of the upper beams at the other two sides of the pallet.

  • Patent number: 4841879
    Abstract: The stringers of two sets of stringers crossing orthogonally to form a skeleton stringer pallet have edge forkway notches, ends of which notches are formed by crossing stringers so that the upright faces of such crossing stringers serve as a guide for the prong of a forklift inserted into the forkway notches.

  • Patent number: 4782639
    Abstract: A shingle or shake panel is composed of shingles progressively increasing in width from one end of the panel, the narrowest shingle or shake being at least substantially three times the offset between adjacent shingle panels in adjacent courses. Apparatus for making such shingle or shake panels trims the individual shingles or shakes to width, accumulates them in a storage bin or wheel and dispenses the shingle or shakes from such storage bin or wheel to a fabricating table where the shingles or shakes are integrated by a strip secured to their outer face at a location such that the edge of the strip farther from the butts of the shingles or shakes is spaced from the butts of the shingles or shakes a distance equal to the weather exposure of the butt portions of the shingles or shakes.

  • Patent number: 4586309
    Abstract: A panel composed of wood sawn tapered shingles including an undercourse of longer shingles and an upper course of shorter shingles disposed with the tips of the shingles in the two courses even and the shingles of the two courses being integrated by staples penetrating both courses of shingles and extending into a narrow cleat behind the undercourse of shingles. The lower edge of the cleat is spaced from the butts of the shingles of the undercourse for engagement with the tips of the shingles of the next lower panel to serve as a gauge for establishing the relative positions of adjacent upper and lower panels applied to a roof or sidewall.

  • Patent number: 4391076
    Abstract: Generally rectangular wood shake covering elements laid up in overlapping courses are spaced apart transversely of their lengths by sawn wood shingle filler elements. Preferably the major portion of the overlapped portion of each course is formed by the tips of the sawn shingle filler elements, whereas the major portion of the exposed portion of each course is formed by the wood shake covering elements. One of such elements can be notched providing a transversely extending shoulder dividing such element into tip and butt portions of unequal width. In application, the shoulder tightly abuts the adjacent element. The covering and filler elements can be used to construct a roofing panel which includes a sawn shingle underlayer beneath each course and waterproof paper which underlies at least the major portion of the shingle underlayer but which is secured to the roofing panel by having one end portion interposed between the underlayer and the covering or filler element at one end of the panel.

  • Patent number: 4295314
    Abstract: The longitudinal sides of rectangular wood roofing shakes are stepped providing transversely extending shoulders facing the shake tips and dividing each shake into a narrower tip portion and a wider butt portion. In application, rectangular fillers are located between the tip portions of adjacent shakes with the butts of such fillers tightly abutting the shake shoulders. The width of each filler is substantially greater than the combined depths of the shake shoulders it abuts such that the adjacent longitudinal sides of the butt portions of the shakes are spaced apart a substantial distance.
