Abstract: A railroad car truck including a first side frame, a second side frame, a bolster, and a first plurality of warp restraints, each first warp restraint configured to prevent warping of the bolster relative to the side frames. Various embodiments include opposing bearings of each warp restraint that engage each other.

Abstract: The Hat Display Device comprises an adjustable spacer, and two shaped blocks. The spacer may include one or more apertures to permit attachment of the Hat Display Device to a support stand.

Abstract: A portable apparatus that allows users to block, steam, stretch, and/or dry ball caps, including a kit and methods. The ball cap is placed onto the steamer. The steamer has a hemispherical back portion that provides steam, and a front portion that moves to stretch the ball cap while excluding steam from the decorated front portion of the ball cap. The ball cap can be stretched, with or without steam, to adjust the size of the cap. The ball cap can be hot-air dried by the apparatus to block the ball cap to the correct shape. The front portions may be interchangeable with different front portions having different shapes.

Abstract: A first arcuate band and a second arcuate band include a threaded rod and a ratchet rod, respectively, secured to one another by an adjustment block to define the operative elements of a hat stretcher. A pair of pawls, lockable in place, extend from the adjustment block to lockingly engage selected ratchet grooves of the ratchet rod and provide coarse adjustment. A threaded bore in the adjustment block threadedly receives the threaded rod to provide fine adjustment. Release and reengagement of the pawls with the selected grooves eliminates the need for readjustment of the hat stretcher between periods of use with a same sized hat.

Abstract: A hat size maintainer includes first and second arcuately shaped members configured to the shape of the interior surface of the headband of a hat or cap. First and second adjustable members, one end of each being attached to one of the first and second arcuately shaped members are adjustably joinable to enable the spacing between the first and second arcuately shaped members to be varied for different hat or cap sizes.

Abstract: A hat stretching device including a spaced apart pair of oppositely facing hat engaging arcuate bands which are interconnected by an adjustment block. One of the arcuate bands and the adjustment block cooperatively define a ratchet mechanism which allows the spacing between the hat engaging bands to be quickly, easily, and repeatable set to a coarsely adjusted size. The other arcuate band and the adjustment block cooperatively define a threaded adjustment mechanism which allows the spacing between the hat engaging bands to be finely adjusted to a precise hat engaging size.

Abstract: What may be termed a low-boy machine is provided with a side-positioned air-supplying blowing chamber, an air heating and upwardly and directing chamber-defining base part, a centrally disposed upright support post or column, an upright steam burst and heat-applying pipe assembly, an upper platform frame on the column that carries cap-finishing means, and a non-permeable bag positioned to extend upwardly between the base part and the upper frame to define a fluid-directing and mixing chamber for supplying steam and hot air to the cap-finishing means. The cap-finishing means has a pair of perforated cap-receiving and stretching parts through which steam and heated air is supplied to the inside of a fabric cap to be finished. The pair of parts have means for relatively moving them towards and away from each other to release and stretch a cap that is positioned thereon.
