NEW STYLE DOUBLE CLAMP. For many classes of work these Clamps will readily take the place of ordinary hand screws, and of course are verymuch stronger and more durable. The illustration shows the construction quite well. The screws are of steel 1 inch in diam. Flanges attached to the ends of screws; heads of screws are square to fit hand wheel. Surface of base against which stock is clamped is planed true, and the top and base castings are joined by steel rods. Distance from steel rod to outer end of base 3 in.; distance from top and bottom castings 16 in. These Clamps have holes in top of base suitable for 1 in. gas pipe, and by slipping as many clamps as are required on the pieces of pipe, as shown in illustration, the stock can be easily and quickly placed in position and the pressure applied. After one side has been filled the clamp can be turned over and the other side filled in the same manner. Price of Double Clamps, $3.50 each. This does not include Hand Wheels, which are $0.50 each. Our reason for pricing these separately is, that in many cases only one or two Hand Wheels would be desired for a large number of Clamps.
