Propeller-Wheel.
Patent for "a construction of propeller-wheel that will permit a large reduction in the wheel-diameter without impairing its effectiveness, and which will thereby bring the resistance nearer to the crank-range of the motive power, and also to increase the bucket or blade surface of the wheel and at the same time afford such clearance at the center of the wheel as will relieve resistance to easy operation of the engine or motive power." (Lines 18-27) Includes instructions and illustrations.
Pump.
Patent for a pump "whereby the pressure exerted upon the liquid in the pressure-pipe is alternately high and low, the high pressure being utilized to elevate the pump-rod, giving a rapid upstroke, and the low pressure to lower said rod gradually and insure a return flow of the liquid in the pressure-pipe." (Lines 26-33) Includes instructions and illustrations.
Ratchet-Wrench.
Patent for a wrench that uses friction-rollers to clamp the thing that is being turned. A rotary ring-shaped cam is what actually turns the wrench's object, and there are teeth that surround the outside of the cam. A pawl, when turning the handle, turns the teeth. This is what makes the cam rotate.
