McPherson Hose Shoe Aids Men Patents have been granted to Duncan McPherson for a hose shoe which is now being marketed by the General Apparatus Corporation, Los Angeles, Cal. The device was designed to be instantly attached to a hose back of the nozzle to simplify the work of handling charged lines under pressure. The empty hose can be mounted on the shoe with an open nozzle pointed at an object. The water pressure can then he turned on from a remote point and the device will not move hut will hold the line in position. The shoe weighs thirty-three pounds. An attractive rack is provided for holding the hose shoe on the running board. On the ground, the hose shoe converts back-pressure into a downward pressure.
