  • Patent number: 4722374
    Abstract: A wooden spiral staircase having a hollow central support column, treads which abut but do not attach to such column, tread supports ending in tenons which completely intersect the column and are secured by a wedged-through mortise joint, spacerblocks between every two adjacent treads and under the bottommost tread, and an optional laminate bent handrail and optional balusters which serve no support function, enabling the manufacturer to construct and ship the main body of the staircase as a single unit that can easily be installed through "screwing" it through the doorway(s) of the intended site. The method of constructing such a staircase in which the placement of the mortises on the central column is determined by the use of a computer generated template, thereby allowing for every staircase to be custom-designed as well as ensuring extreme precision in the final product.

  • Patent number: 4720989
    Abstract: An I-beam blank is rolled from a bloom by rolling into opposite edges of the bloom respective central triangular section notches of predetermined apex angle, apex radius of curvature, width, and height in a succession of roll passes. According to this invention the radius and apex angle of the notches are progressively increased a plurality of times during the succession of roll passes. Then the notches are pressed by rolling generally out of the bloom edges in at least one final rolling pass, thereby flattening these edges. The rolling passes are carried out between respective pairs of rolls having facing grooves bases and the roll pairs of the grooving steps are formed with respective triangular-section ridges complementary to the notches being formed. In addition the bloom is rolled repeatedly in the first pair of grooves until the material of the bloom flanking the notch mainly fills these grooves, that i until the bloom bottoms in the grooves.

  • Patent number: 4717613
    Abstract: A cushioning dunnage producing mechanism and method wherein the mechanism utilizes one or more webs of sheet-like stock material, with the stock material being adapted to be disposed by the mechanism in generally superimposed relation and then fed into a crumpler section of tubular-like construction, to radially compress the sheet-like material into a pad-like dunnage product. The lateral edges of the stock material are caused to be rolled inwardly into generally spiral-like form, prior to passage of the stock material into the crumpler section, by a forming frame of generally triangular-like shape both in plan and in side elevation, with the nose of the forming frame being disposed closely adjacent the entranceway to the crumpler section. Meshed spur gears coacting with the crumpler section, coin or stitch the confronting portions of the rolled edges of stock material together, to hold the produced dunnage product in a pad-like configuration.

  • Patent number: 4711278
    Abstract: A tree pruning machine which has a body for vertically elevating on a standing tree through a wheel driven by an engine, a rotary device for turning on the periphery of the body, a cutting unit provided in the rotary device and having a detector for detecting the cutting resistance effected from the cutting branch, and a rotating speed reduction unit of the rotary device, wherein the rotating speed reduction unit is controlled by the detector of the cutting resistance. If a branch having a large current resistance such as a thick or hard branch makes contact with the cutting unit, the detector detects the contact of the cutting unit with the branch having large cutting resistance, the contact is detected by the detector to decelerate the rotating speed. Thus, the pruning machine can cut branches of a standing tree having large cutting resistance such as thick or hard branches.
