Abstract
An asymmetrical vibrator is provided, which is actuated by compressed air. The vibrator operates in a case, which has two bores disposed parallel on opposite sides of the casing. One of the bores is smaller than the second bore and the piston operating in the small bore is called the slow piston, since it is actuated with air to a relatively slow motion and the piston operating in the second larger bore is called the fast piston, since it is moves at a larger speed when driven directly by the compressed air. The asymmetric vibration motion can be employed to transport materials upwardly in factories and assembly stations. The air operated asymmetric vibrators need low maintenance and do not entail the spark dangers caused by the presence of electrical wiring for electrical drive motors.
Claims27
An asymmetrically accelerated vibrator comprising:
- a case having a first bore and a second bore arranged in coaxial relation to one another and in regulated fluid communication with a source of compressed fluid wherein a compressed fluid conduit is defined within said case, and arranged in fluid communication between a compressed fluid intake port and a threaded recess that is defined in said case;
- a first piston having a first diameter disposed in said first bore;
- a second piston having a second diameter disposed in said second bore;
- a mechanical connection between said first and second pistons such that said pistons are caused to oscillate in unison by regulated application of compressed fluid from said compressed fluid source;
- and
- a ball-valve disposed in fluid regulatory relation between said first bore, said second bore, and said source of compressed fluid so as to switch a flow of said compressed fluid between said first bore and said second bore upon interaction with a portion of said second piston.

An asymmetrically accelerated vibrator comprising:
- a case having a first open-ended chamber and a second open-ended chamber arranged in coaxial relation to one another and in regulated fluid communication with a source of compressed fluid;
- a first piston having a first diameter disposed in said first open-ended chamber;
- a second piston having a second diameter disposed in said second open-ended chamber;
- a compressed fluid conduit defined within said case and arranged in fluid communication between a compressed fluid intake port and a threaded recess that is defined in said case between said first open-ended chamber and said second open-ended chamber wherein said threaded recess is terminated by a radiused seat-wall having a through-bore that opens into said second open-ended chamber;
- a mechanical connection between said first and second pistons such that those pistons are caused to oscillate in unison by regulated application of compressed fluid from said compressed fluid source;
- and
- a ball-valve disposed in said threaded recess such that when said ball-valve is engaging said seat-wall, a segment of said ball-valve projects into said second open-ended chamber so as to be engagable by a portion of said second piston and thereby to provide fluid regulation between said first open-ended chamber, said second open-ended chamber, and said source of compressed fluid so as to switch a flow of said compressed fluid between said first open-ended chamber and said second open-ended chamber upon interaction of said segment with said portion of said second piston.
