Protecting an Air Pump against Denting
Denting of Tire Pumps is Prevented by the Use of a Case Like That Shown
The brass cylinders of many tire pumps are made of thin metal, and a slight blow may dent them. Such injuries interfere with the action of the plunger, making the pump almost useless. A case which will afford protection to the pump is shown in the sketch. It was made of two strips of wood cored out on the inner sides to fit the pump and provided with small hinges and hooks, to lock it into place.
