  • Patent number: 5058231
    Abstract: A street sweeping broom includes a helically formed brush strip which is tightly secured about the periphery of a rigid cylindrical core. The brush strip is of conventional construction including a plurality of reversely bent bristles with the bights thereof being maintained within a channel member by an anchoring wire and by crimping the sides of the channel member at spaced locations along the length thereof. At least one end of the helical brush strip is secured to a guide member which also secures the coil directly adjacent to the end of the brush strip so that the end coil thereof may not change diameter. A ring having a plurality of circumferentially spaced slots is secured to the end of the cylindrical core and the guide member is mounted on the ring in a fashion which allows movement of the guide member about the circumference of the ring in one rotational direction only.
