Abstract:

A caster wheel brake system for a mobile support system such as a cart or other wheeled structure is operable to selectively secure caster wheels against rolling rotation. The system includes a caster wheel assembly and a braking mechanism mounted nearby. A pair of brake actuation inputs, such as handles or levers, can be secured to the cart and independently operated to rotate a rotator link, which in turn rotates a brake-actuating link. Rotation of the brake-actuating link deactivates the braking mechanism to allow rolling rotation of the caster wheels. Optionally, the operation of one of the handles to deactivate the braking mechanism has no effect on the other handle.

Abstract:

A caster wheel brake and anti-swivel system for carts and other wheeled articles is operable to secure free-castering wheels against swiveling rotation about their swivel axes, and against rolling rotation along their horizontal rotation axes. The system includes a swiveling caster wheel assembly and an actuation link, with an anti-swivel actuator and a brake actuator coupled thereto. Linear movement of the actuation link causes the anti-swivel actuator to engage the anti-swivel member that rotates with the caster wheel about the swivel axis, to selectively prevent the anti-swivel member and wheel from swiveling. The actuation link's movement also urges a brake actuator to move a wheel brake and drives a braking surface into engagement with the wheel, thereby preventing the wheel from rolling at the same time it is prevented from swiveling by the pawl. Optionally, a foot-operated torque shaft and a rack-and-pinion arrangement are used to operate the actuation link.

Abstract:

A plant product extraction apparatus or extractor is provided for separating or grading fine particles from a larger portion of material, such as separating trichomes from a stalk or flower of a plant. The apparatus imparts a plurality modes or patterns of oscillations and vibrations to a particle separator or sieve that holds the plant matter. A motor drives a back and forth motion to a support platform supporting a sieve. The sieve is constrained by a retention tray that is supported by the support platform. Vibratory motors provide rapid shaking vibration through the retention tray to the sieve. Agitators may be placed inside of the sieve to facilitate the separation of the plant materials. The various motors and locomotion patterns facilitate the separation of finer plant materials from a larger portion of a plant.

Abstract:

A product sorting apparatus is operable to sort products by inducing an oscillating or rocking motion to a plurality of sorting trays in a vertically stacked arrangement. A subset of the products in a top-most tray selectively pass to successive sorting trays. Each of the sorting trays is configured to receive and selectively transmit the selected products according to a separator or sorting panel that is disposed between an input and an output of a given tray. Each of the separator panels defines apertures that facilitate sorting of the products according to size and/or shape. The rocking or oscillating motion has an amplitude and a period according to an input from a drive mechanism, which may include a motor and drive link with a controller and/or a power switch. Optionally, a safety cage and one or more cutoff switches are provided for protecting the sorter and personnel.
