  • Publication number: 20070281601
    Abstract: A snap-on downwardly deflecting air diverter for freeblow evaporator and/or heating units. The diverter includes a hood having a closed upper section and an open bottom section defined by a front panel and two side panels that extend generally perpendicularly from the front panel. The free edge of-each side panel has at least one fastening element for removably securing the diverter to the outlet grille of the evaporator and/or heating unit. With the diverter in place, air exiting the evaporator and/or heating unit passes through the grille and, in that area covered by the diverter, strikes the inner surface of the hood and is directed downwardly through the open bottom section.

  • Patent number: 7246502
    Abstract: An air conditioning unit having a flush-mounted self-contained evaporator assembly adapted for mounting into the front or rear bulkhead of a bus or similar type vehicle. The evaporator assembly includes a specially designed housing to provide a compact self-contained unit that can fit in a small space, such as the bulkhead above a passenger compartment, while the associated compressor and condenser units are distally located. The housing has chamfered top surfaces so as to provide additional clearance within the bulkhead during installation, and a floor pan with two sloping surfaces forming an inverted apex. Lateral drains located at both ends of the apex facilitate drainage of condensate from the unit when the vehicle is in motion or in a non-level stationary position.

  • Patent number: 5161515
    Abstract: The reversible archery arrow holder rest device includes a bracket having a side plate mounted on an archery bow sidewall, and a rear clamp. The clamp adjustably holds a pair of vertically spaced cross-arms behind the bow riser, which arms extend transversely to a point behind the bow window and support a pair of blades, namely, the rest blade and the holder blade. Thus, the rest includes an upwardly and forwardly projecting resilient blade, the front end of which has a side surface which slopes downwardly towards the bow sidewall. The holder is above the rest and includes a downwardly and forwardly extending resilient blade, the front end of which has a side surface which slopes upwardly towards the bow sidewall. A first arrow vane-receiving space is between the front ends of the rest and holder. A second connecting space is defined by the rest, holder and bow sidewall and receives the remaining vanes and shaft of the arrow for free clearance during arrow flight from the bow.

  • Patent number: 4703745
    Abstract: An attachment for a bow to be used in cooperation with known supports which engage respectively a side of an arrow and also the lower surface of an arrow. The attachment has a flexible leaf and a cam head. An arrow is mounted to the known supports by moving the arrow shaft laterally against the cam head flexing the leaf upwardly. As the arrow shaft moves past the cam head the leaf snaps back downwardly pressing the arrow against the aforementioned known supports, whereby the attachment acts to prevent an arrow from laterally falling from the bow when mounted on the bow in any shooting position of the bow but not interfering with longitudinal movement of the arrow from the bow when shot therefrom.
