    Abstract: A dual wheel caster (10) having a vertical pintle (16) in a central horn (11) to accommodate swivelling movement of the caster (10) with an integral forwardly extending projection of "nose" on the horn (11) having an upwardly inclined lower surface (41) that slides up on relatively high obstruction (60) to raise the forward end of the supported article (61) to reduce the possibility of a caster supported article tipping over in a forward direction. The horn (11) has an integral arcuate projection (50) adjacent this anti-tipping slide surface (41) to permit the caster (10) and the supported article (61)to ride up and over lower obstructions such as inclined door skills (63).

    Abstract: The following specification describes a caster in which a footoperated treadle rotatable about the wheel axis pivots an Lshaped integral spring lever and brake into engagement with the caster wheel and thereafter tenses the spring lever to hold the treadle, lever and brake in their operated position until released.

    Abstract: A caster brake and latch assembly consisting of a treadle pivotable about the axis of the caster wheel to pivot an L-shaped brake element into braking engagement with the caster wheel periphery. A pawl pivotally mounted on the caster horn is pivoted with the brake element to engage between the teeth of a latch member secured to the caster pintle. The pawl and latch engagement latches the horn to the pintle to prevent relative rotation therebetween.

    Abstract translation: 一种脚轮制动器和闩锁组件，其包括可围绕脚轮的轴线枢转的脚踏板，以将L形制动元件枢转以与脚轮轮周边制动接合。 枢转地安装在脚轮角上的棘爪与制动元件枢转以接合固定到脚轮枢轴的闩锁构件的齿之间。 棘爪和闩锁接合将喇叭闩锁到枢栓以防止它们之间的相对旋转。
