Abstract: An eccentrically rotatable chair comprises a base having a horizontal surface and a central support fixedly secured to the base. A horizontal arm extends from the central support and is connected with the support by a longitudinally extending anti-friction lineal bearing in the arm engaging an annular flange on the central support so that the arm can move longitudinally and can rotate about the central support but is restrained from rotation about the longtudinal axis of the arm. A seat is supported at the outer end of the arm and a ball bearing at the outer end of the arm can roll in any direction on the base. With this construction the seat can be moved toward and away from the central support and can orbit around the central support but is maintained upright by the bearing connecting the arm with the central support. In one embodiment the central support is a vertical post with two annular flanges spaced vertically from one another.

Abstract: Apparatus for making tubular articles formed of a length of material wound in helical form with contiguous edges of successive convolutions of the material joined with one another comprises a forming section made up of a plurality of guide rollers supported by a vertical arch-type frame so as to define a generally cylindrical configuration. Feed rollers propel a strip of material in a lengthwise direction through the arch of the frame and around the support provided by the guide rollers in a helical path with edges of successive convolutions of the helix abutting one another. As the material is thus in effect coiled into helical form, a sewing machine joins contiguous edges of successive convolutions to form a continuous tubular article.

Abstract: A pants-type garment comprises two bands of material, one for each leg, and a side extension piece which extends at an angle from one side of an upper portion of each band. Each of the bands together with its side extension piece is wound helically and adjacent edges of successive convolutions are joined in a helical junction line to form a leg and associated body portion of the garment. The two body portions are then joined to form the garment. To provide greater fullness, a V-shaped crotch band is joined to upper edge portions of each band and respective side extension piece and the two crotch bands are then joined along a central junction line. The V-shaped crotch band may be used without the side extension pieces and may be used in pants-type garments having legs and associated body portions formed of panels with vertical rather than helical seams.

Abstract: The inner ends of cover-supporting ribs of an umbrella are pivotally connected to a rib carrier which is longitudinally slidable in a hollow shaft by means of a projection extending out through a longitudinal slot in the shaft. The rib carrier is slidable between a closed position in which the rib carrier is near the lower end of the shaft and the rib members together with the cover are in the shaft and an open position in which the rib carrier is at the upper end of the shaft and the rib members radiate out from the rib carrier so as to support the cover. Each of the ribs comprises inner and outer tubular sections which are telescopically slidable one in the other. When the umbrella is in open position, the telescopic ribs are extended so as to support a larger cover. When the umbrella is in closed condition, the telescopic ribs are contracted so as to be received in a shorter shaft.

Abstract: A pants-type garment comprises two panels of material each comprising a lower leg-forming portion and an upper body-forming portion having a contoured edge defining a generally U-shaped cutout for the formation of a crotch. A crotch band has opposite side edges joined respectively with the contoured edges of the two panels to unite the panels and thereby form a body portion of the garment. Each of the two panels may be a band of material which is wound helically to form a leg of the garment with adjacent edges of successive convolutions stitched together.

Abstract: A body-type garment, i.e. a garment intended to cover at least a portion of the torso of the wearer comprises a strip of material having generally parallel side edges and inclined end edges defining at least approximately a parallelogram shape. String passages, for example a hem or fold, extend at least along the side edges of the strip. The strip is coiled into helical form about the body of the wearer with side edges of adjacent convolutions of the strip adjacent one another. String extending through the string passages is drawn taut and secured so as to hold the side edges of adjacent convolutions adjacent one another. A pants-type garment comprising a body portion and two leg portions extending downward from the body portion has each leg and an associated portion of the body portion made from a strip of material likewise having side edges and inclined helical edges defining at least approximately a parallelogram.

Abstract: A table suitable for many uses comprises a rectangular prismatic base having a vertical well located near one corner and a rectangular table top having near one corner a downwardly extending supporting post rotatably received in the well of the base and longitudinally slidable therein. A pin projecting inwardly in the well is engageable in a longitudinal slot in the top-supporting post and, when the table top is raised, is engageable with a lower end surface of the post to support the table top in raised position while permitting rotation of the table top relative to the base. The post also has a downward extension at the lower end of which there is provided a notched disc which is also engageable with the inwardly projecting pin of the well to support the table top rotatably at a third height. In another embodiment the base is larger and has wells at opposite sides to receive the supporting posts of four table tops.
