Abstract
372,042. Excavating &c. BAILLIE, S., Pool Hayes Colliery, Short Heath, near Wolverhampton. March 23, 1931, No. 8859. [Class 68 (i).] A hammering tool for excavating, mining, &c. comprises a rotary member or pair of members 1, a hammer 9 freely movable vertically in frames 10 beneath the members 1 and a chain &c. 11 secured to the hammer and having a pin 12 engaging internal recesses 1d in the members 1 whereby upon rotation of the latter the hammer is raised and released automatically in its highest position. The rotary members may take the form of two parallel discs having rings 1b secured to their adjacent faces, the rings being formed with recesses 1d on their inner peripheries. Alternatively, a single disc may be used, Fig. 3, having a diametral slot 1f and recesses 1d to accommodate the pin 12, the disc being supported by rollers on its outer periphery. The disc may be driven through gearing from a motor mounted on the frame 10 or from a remotely disposed motor through a flexible shaft. The whole mechanism may be enclosed or mounted in an open frame provided with handles.
