Anti-Friction Wagon Slide.

Patent for a new and improved anti-friction wagon slide. This design "consists of flat side pieces provided with bolt-holes near their ends, and connected to diametrically-opposite points of nearly-cylindrical end pieces, which have holes through their axes for the reception of the roller-shaft. The recess is so formed that the lower portion of the end pieces shall bear against its ends when the frame is put in place.
