Abstract: This invention pertains to induced vibration and the dampening of these vibrations in the motor means. Vibration induced by rotating a shaft having eccentric weights thereon has been used to produce all kinds of shaking apparatus including large car shakers in which the induced force may be as much as eight thousand two hundred pounds. These vibrations can be as much as five thousand six hundred vibrations per minute and can be used for huge bins and hoppers in which the capacity may be as much as one hundred fifty thousand pounds. Vibrators using air, electric or hydraulic motors can be tuned or adjusted to provide the desired results. Most of these vibrators using a tuned motor may be temporarily or permanently attached. Motor driven vibrators, as far as is known, transmits the vibrational force into the shaft of the motor. Said motors, which are usually standard off-the-shelf units have their rotor bearings designed for rotary motion rather than combined with a vibratory force.

Vibrations induced by rotating a shaft having eccentric weights thereon have been used to produce all kinds of shaking apparatus including large car shakers in which the induced force may be much as eight thousand two hundred pounds. These vibrations may be as much as five thousand six hundred vibrations per minute and may be employed in hugh bins and hoppers in which the capacity is as great as one hundred fifty thousand pounds. Vibrators using air, electric or hydraulic motors can be tuned or adjusted to provide the desired results. Most of these vibrators using a tuned motor may be temporarily or permanently attached. Conventional motor driven vibrators, as far as is known, transmit the vibrational forces into the shaft of the motor. Said motors, which are usually conventional off-the-shelf units have their rotor bearings designed for rotary motion rather than combined with a vibratory force.

Abstract: This invention pertains to unidirectional vibration apparatus using resilient shock absorber mounting means to change multidirectional vibration into unidirectional vibration forces. Three embodiments pertain to the use of pressurized air for driving an eccentric weight at a desired speed. One embodiment employs a turbine which is carried between and by resilient disk members secured to mounting rings. A roller is driven by pressurized air and the vibrating apparatus is carried within and by a resilient ring. A ball vibrator also uses a resilient ring as a shock absorber.

Abstract: This invention pertains to cleaning apparatus for a conveyor belt. This cleaner employs gravitational force to apply vibratory action on the conveyor belt. A free-turning roller engages the inner surface of the returning extent of the conveyor belt at a point and position near the tail pulley. Four embodiments are shown. The first shows the motor and vibrated pulley disposed between the extents of belt. The second embodiment has the motor disposed below the return extent of belt. The third embodiment in which the belt extents are too close together to mount the motor between the belts has the motor disposed above the incomming belt. The fourth embodiment shows vibration isolators which are used to reduce any transmission of vibrations into the frame supporting the pulleys of the conveyor belt. The vibrated frame is carried in channel shaped guideways lined with a non-metallic liner so the vibrated frame is gravitationally movable in the channels.

Abstract: A container for receiving a charge of pressurized air and storing the air in this container until released through a blast nozzle and having a quick dump valve apparatus within this container. The valve includes a removable pipe which contains a large slidable piston which opens and closes the flow of accumulated air to the discharge. This piston is moved in response to a solenoid actuated small piston which is moved in a small tube. This small tube extends through the large piston which slides therealong.

Abstract: The cleaning of conveyor belts has been a problem since their widespread acceptance and the adoption of belts for the transporting of materials. Many materials so conveyed have a tackiness and/or an affinity or attraction for the outer surface of a conveyor belt. When this attraction occurs, the cleaning or removal of this material from the surface of the belt is a problem. Many methods have been used for removing this material or residue adhering to the conveyor belt. In the present invention there is shown a vibration device which is attached so as to vibrate the lower belt extent. This apparatus is carried on the under and inner side of the conveyor belt so that a vibration occurs shortly after the discharge of the material from this belt.

Abstract: A container for receiving a charge of pressurized air and storing the air in this container until released through a blast nozzle and having a quick dump valve apparatus within this container. In one embodiment a valve includes a removable pipe which contains a large slidable piston which opens and closes the flow of accumulated air to the discharge. This piston is moved in response to a solenoid actuated small piston which is moved in a small tube. This small tube extends through the large piston and it slides therealong. In another embodiment a ball valve is employed in a tubular chamber. An external three-way quick acting valve actuates the flow of pressurized air to the valve and to a venting to atmosphere. The ball is slightly smaller than the internal diameter of the tubular member so that pressurized air may flow by the ball in a forward position and into the container.

Abstract: The cleaning of conveyor belts has been a problem since their widespread acceptance and adoption for the transporting of materials. Many materials so conveyed have a tackiness or an affinity for the outer surface of the belt of the conveyor. When this occurs the cleaning or removal of this material from the surface of the belt becomes a problem. Prior to the present invention scrapers, brushes and similar devices have been widely used for removing this material or residue adhering to the conveyor belt. In the present invention there is shown a vibration device which is attached so as to vibrate a roller. This device is carried on the under and inner side of the conveyor belt so that this vibration occurs shortly after the discharge of the material from this belt. Shortly after passing over the discharge roller the conveyor belt is brought in way of a vibrated roller whereby any residual material on the exterior of the belt is loosened and knocked free by means of the localized vibrations.

Abstract: This invention relates to a vibrating table where a rotary motion vibrator is used to provide vertical oscillations. In this table top arrangement the vibrator is secured to a frame or lower plate member preferably at or about its midpoint. This lower frame member is conventionally supported by a support base through vibration isolators such as coil springs provided at its corners. To at least two edges of this lower frame member are secured transfer pads which also are secured to the like edges of and carry the upper table top a spaced distance above the lower frame. The resulting vertical motion and frequency are equal or substantially equal at all portions of the table top and there is an absence of "dead spots." Conventional table tops of vibrating tables to which the vibrator is directly secured have a dead spot or spots and the amplitude is unequal causing the material or product thereon to walk or move to one side.

Abstract: This invention pertains to an air-actuated vibrator of the turbine-type in which the rotor and enclosing chamber is contoured so as to provide within the normal operating range a low noise level which is below 80 db (hertz). In association with this chamber is a novel muffler which receives the output from the chamber and reduces the noise level to about 65 db or less which is much below the tolerance level established as acceptable. The rotor is the only moving part in this vibrator and has its periphery formed with small tooth-like transverse serrations but other similar profiles may be used. The tooth profile is of such small size that the driven rotor which is peripherally driven by pressurized air within a normal supply range produces noise levels which are sufficiently low so that the operation of the vibrator in combination with the associated muffler is considered to be virtually silent.

Abstract: This invention pertains to turbine-type vibrators in which the rotor member has the blade portions arranged in an annular pattern. The blades extend substantially at right angles to the plane of rotation of the rotor. The blades are carried on and extend from the side of the rotor and may have one or two parallel rows. When two rows of blades are provided one row is arranged on each side of the rotor and a divider is preferably provided between the blades. Each annular grouping has its own inlet and its own outlet.
