Machinery Made from Scraps

��The material from which it was made was strewn about camp, and was mere junk

��WHEN the time came to pave the top of the Kensico Dam, in New York, the superintendent, George H. Angel, didn't go to the extra expense of purchasing new paving equipment.- He took a hurried inventory of the odds and ends of machinery that lay about the con- struction camp and decided that he could make some machinery of his own out of them.

Our illustrations show what he did with a few pieces of discarded pipe, wheels, nuts, bolts, etc. A roller was made by fitting an old belt-pulley with a wrought-iron handle. The asphalt-heater was made out of an old steel form that had been used for casting concrete blocks. By riveting in a false bottom near the middle of the form, cut- ting a door in the lower half at one end and riveting on a hinged cover and smoke stack, the heater was ready for use. The asphalt was placed in the upper half and a wood fire was built underneath the false bottom.

The mixer for the mortar was made by joining flanges to the ends of a short length of riveted steel pipe and by bolting cover plates to them. An axle with paddles ran through the center and the propelling force was a small motor placed at one end. The machine was mounted on an old wagon body.

The roadway across the top of the dam

���An old steel form for concrete blocks was converted into a heater

is twenty-one feet wide and two thousand, five hundred feet in length. There is a cement sidewalk on one side and a concrete curb on the other, each about eight inches above the surface of the roadway gutter. The forms for the concrete were all made from scrap material which was readily obtainable at the camp, and a locomotive crane was used to transport the cement from the mixer to the roadway, where it was spread by hand. The machinery made from odds and ends gave as good service for the purpo e as new machinery.
