Abstract: A lobby dust pan of the type generally having a receptacle portion pivotally connected to a yoke. The yoke is flexible and is connected to a shaft. The yoke is deformable to enable latching means thereon to be retained with or released from a slot on the receptacle. The shaft in turn is connected to a novel handle having an axially extending body portion, a connecting portion formed proximate one end of said body portion and connected to the upper end of the shaft, and a transverse downwardly extending ridge portion formed at the other end of said body portion. The novel ridge portion of the handle permits the lobby dust pan to easily be carried over the arm of the user when moving from job to job, thus freeing the hands for other purposes. Also, it allows the lobby dust pan to be "hooked" over receptacle containers when temporarily not in use.

Abstract: An agitator of impeller shape includes an agitator hub with a plurality of radially extending arms for attachment to a drive shaft for the mixing of substances in vessels, such as substances that tend to material build-up, incrustation and/or incipient polymerization. The hub is totally closed by welding a cap over the end of the hub. At least one of the agitator arms is formed of two components, a shorter stub arm attached to the hub and longer main arm. Both components are formed of a pair of parallel, spaced apart tubes connected by a pair of webs. Each tube includes a bushing for retaining a centering bolt to attach the main portion to the stub portion. The two components are then welded together and polished to remove any gaps and sharp edges.
