This invention relates to material conveying apparatus of the type employing a vibrating conveying surface and relates, more particularly, to a novel vibrator for use with such conveying apparatus and to combination of the vibrator with conveyors of various types. The aim of the present invention is to provide an improved mechanism for imparting vibrations to conveyor surfaces such as utilized in feed hoppers and transfer rails.
Included in this aim is the provision of a simple compact mechanism which will have a long trouble-free service life, which will produce the desired vibratory movement and without varying the position of the conveyor relative to the base, which is conveniently adjustable in use of variable amplitude and of variable vertical to horizontal component rates, and which is relatively unaffected by variations in load of material being conveyed.
