Abstract: The wall portion of a chain-type 4-wheel drive vehicle transfer case disposed adjacent and generally paralleling the slack reach of the transfer case chain when the associated vehicle is being driven in a forward direction has an opening formed therein registered with the midportion of the slack reach and a mounting plate having an opening formed therein is secured in position over the external surfaces of the wall portion with the openings registered with each other. One end of a guide sleeve is secured to the outer surface of the mounting plate in registry with the opening formed therein and an elongated shank member is slidably supported from the sleeve and projects through the registered openings with one end of the shank member projecting into the sleeve and the other end of the shank member projecting into the transfer case.

Abstract: A cage-type enclosure is provided for the lower end portions of the upstanding power leg of an outboard marine propulsion unit from which the propeller of the unit is journaled with the cage enclosing the propeller and thus protecting the latter from fouling by weeds and other underwater debris and also serving to prevent accidental injury due to body portions of persons disposed in the water adjacent the propulsion unit from coming in contact with the enclosed propeller. The cage is generally egg-shaped in horizontal plan, inverted U-shaped in vertical transverse section and fin-shaped in side elevation including a forwardly and upwardly curving forward end portion, a substantially vertical rear end portion and a horizontal upper portion. The cage includes clamp structure at its upper end for removable clamped support from the power leg of the associated outboard marine propulsion unit adjacent the cavitation plate thereof.
