摘要： A vacuum-blower unit has an intake connected by a flexible hose to a molded plastics boot pivotally connected to the discharge portion of a rotary mower deck mounted on a riding tractor. The boot is also supported in horizontally spaced relation to the deck by a caster wheel to form an air gap and is adapted for convenient connection with decks of different sizes and configurations and having either a right or left discharge. The boot is cut to form an opening somewhat larger than the discharge outlet of the mower deck to extend the air gap which cooperates with air intake holes in the boot to avoid clogging of the boot with grass clippings, leaves and other debris transported by the vacuum-blower unit through flexible ducts to a trailing wheel supported cart. The cart includes a body enclosed by a canopy having an elongated top air discharge outlet covered by a screen and a row of independently pivotal louvers. The cart encloses a set of abutting containers which receive the debris and may be lined with disposable bags, and the containers are individually removable from the cart after the rear door of the cart is opened.

摘要： A cleaner system providing a compact package capable of installation and use in a minimal of space and substantially without loss of space by reason of its configuration. The arrangement provides for free access to all components. In preferred embodiment the system features vertically oriented pipe-like conduits serving as accepts and rejects headers which per se support vertically spaced pairs of cleaners connecting directly to said conduits in straight line configurations and with their rejects ends lower than their accepts ends. The cleaners of each pair are arranged parallel and functionally coupled to provide that to one end their accepts move in essentially parallel straight line flow to and tangentially inward of respectively opposite sides of the interior wall surface of the related accepts conduit. Their rejects flow in like fashion to and tangentially inward of respectively opposite sides of the interior wall surface of the related rejects conduit. The nature of the entry of accepts and the rejects into the respective conduits provide for an interfering flow pattern which renders more efficient and effective the suction means which are applied to one end or the other of the conduits, in accordance with the desired end results.

摘要： A centrifugal type cleaner or separator, the separating chamber of which is provided, in its interior, with a sudden and sharp reduction of its cross-sectional area by means at the outer periphery of which is an escape passage for the deflected portion of a vortex type flow. The arrangement provides that as a slurry is moved through the chamber in a vortex type flow, the outer portion of the flow including the larger and lighter solids in the slurry, it is intended to reject, will be deflected to the escape passage while the remaining heavy and small solids will find an exit through the underflow nozzle of the cleaner. In the preferred embodiment here illustrated the escape passage is designed to maintain a vortex type flow pattern for the escaping material.
