Abstract: An integral pump and drain apparatus is contained in a common housing structure to reduce the required space needed for these components in the vicinity proximate the engine of a marine propulsion system. The valve of the drain is remotely actuated by air pressure and therefore does not require the boat operator to manually remove plugs or manually actuate mechanical components to cause the engine to drain through a drain conduit that is formed as an integral part of the housing structure.

Abstract: A ski rack for holding several pairs of skis and poles in a vertical position comprising a base, means formed in the base for holding the poles and ski holding means extending perpendicularly from said base.

Abstract: A corner tooth assembly, for an earthmoving implement having an upright sidewall and a cutting edge disposed in laterally extending relation from the sidewall, includes a corner tooth adapter having a hollow rearward portion secured to a lower forward outside surface of the sidewall and a nose portion extending forwardly of the sidewall, and a replaceable wear tip mounted on the nose portion of the adapter protectingly beyond the implement so that loads on the tip during forward movement of the implement are transmitted through the adapter directly rearwardly to the sidewall without affecting the cutting edge.

Abstract: A bulldozer assembly comprises a pair of laterally spaced push arms pivotally interconnected between a blade thereof and a vehicle. A pair of lift cylinders are also pivotally connected between the vehicle and the blade for selectively raising or lowering the blade relative to the vehicle. A tilt mechanism for selectively tilting the normally upright blade in a vertical plane comprises first and second members each pivotally interconnected between the vehicle and the blade on an outboard side thereof. A double-acting cylinder is pivotally interconnected between inboard sides of the members for selectively pivoting the members relative to each other to tilt the blade.

Abstract: A bulldozer blade comprises a push plate having a cutting edge mounted on a lower end thereof and a plurality of structural members secured on the back of the push plate and welded together to increase the structural integrity thereof. Each adjacent pair of such members are joined together at a weldment comprising a groove and contiguous dam formed on a surface of one member to have a corner of the other member disposed adjacent thereto and common weld means at least substantially filling the groove and securing the members together. The groove and dam are preformed on an arcuate portion of the first member during a cold forming operation.

Abstract: An apparatus for forming an elongated groove and contiguous dam on a member, such as the push plate of a bulldozer blade, comprises a pair of support and guide assemblies defining a space therebetween. The member is fed through the space and a forming roller, rotatably mounted on one of the assemblies, forms the groove and dam on the member.
