Abstract: A tool for straightening indentations in sheet metal has a pair of substantially L-shaped rods, one leg of one of the rods being mounted concentrically within a corresponding leg of the other of the rods for movement axially along and rotatable about the common axis. The second leg of the outer rod has a recess shaped for receiving the corresponding second leg of the inner rod so that in a first position the second leg of the inner rod may be nestled within the second leg of the outer rod to provide a cross-sectional profile less than the composite of the two rods and both may be inserted and removed as a unit into and from a hole formed in the sheet metal. The inner rod may thereafter be rotated 180 degrees about the common axis and locked in position for applying a pulling force against the sheet metal. A spring detent locking pin secures the rods in the pulling disposition and also in the insertion/removal disposition of the rods.

Abstract: A tool for straightening indentations in sheet metal has a pair of levers each having first and second legs disposed angularly to one another and a pivot pin for journally mounting the levers together for pivotable movement about the pin. The levers may be pivoted from a position in which the axes of the first legs are superposed upon each other for insertion of both first legs simultaneously into a hole formed in the sheet metal for receiving the legs. The levers may then be pivoted to a second position in which the first legs face in opposite directions from the pivot pin and engage the sheet metal about the hole. In one embodiment the axes of the second legs in the second position are disposed angularly to one another and a spreader member is removably secured to the legs. A clevis member being secured to the spreader member for application of a pulling force. In two other embodiments the axes of the second legs are superposed upon each other and a clevis member is directly removably secured to both legs.

Abstract: A motor vehicle internal combustion engine having a pair of heat risers on the exhaust manifold and a plenum chamber positioned about the carburator fuel reservoir. Air from one of the heat risers is directed into the front of the air cleaner assembly. Air from the other heat riser is directed into the plenum where it preheats the fuel in the reservoir, and then exhaust into the air cleaner assembly where it is mixed with the air received from the first heat riser. Significant savings in fuel consumed by the engine have been noted by thus preheating the air and the fuel without vapor lock occurrences.
