Granted: 1898-01-15
Abstract: 1445. Eberhardt, U. Jan. 19. Milling. - Machines for cutting toothed gearing are provided with a carriage D, reciprocated by a nut b rotated alternately in opposite direction by two trains of wheels, and clutch c' from a shaft L, driven from the shatt J and pulley J<2>. The blank mandrel A<1> is carried by a head F in the standard E, and is rotated by the worm gearing H, I<1>, shaft I, and gearing K with a friction device I<2> from the pulley J<2>. The shaft I is connected by change gearing I<3>, S' with a shaft S carrying a notch disc d with which a pawl e can engage to hold the gearing for rotating the blank stationary at the required time. During the backward traverse of the carriage D a chain p, attached to the bracket P<2>, pulls a detent h to disengage the pawl e, leaving the gearing free to rotate the blank through the required distance. The bracket P<2>, acting on a stop on the rod P, moves over a lever n, which, acting on an arm g<2>, moves the clutch c into its inoperative position, but ready to be pressed over to reverse the direction of rotation of the nut on the screw, by a spring latch l in the lever n bearing against an inclined piece l<1>. The arm g' is prevented from moving till the pawl e again enters the notch in the disc d by a rod N engaging a projection o<2> on a slide o connected by rod o<1> to the arm g<2>. The pawl e is positively moved into engagement with the notch by a cam d<2> acting on an arm f of the pawl, and the arm e<1> at the same time lifts the rod N, releasing the slide o, and allowing the clutch to be shifted. The cam d' may be replaced by a grooved cam on the face of the disc d, engaging a pin on the arm f. For cutting worm-wheels, the spindle Y with the cutter u may be connected with the shaft S by bevel gearing, a shaft t supported in swivelling bearings, and suitable bevel and spur gearing.

Abstract: 16,114. Hamal, L. T. Aug. 8. Banjoes, guitars, mandolins, and like instruments. -The invention relates to a stringed instrument embracing some of the characteristics both of a banjo and a mandolin. Some of the improvements are applicable to both of these instruments, and also to guitars. The body C has a vellum head D, and is made of sheet or cast metal. It may have a back K, made in one with it, or attached to it in any suitable way. The back may also consist of vellum attached to the body in the same way as the head, that is by a ring N tightened by hooks F. The hooks for the head and back are arranged in pairs with right and left handed screws, so that boch members of each pair can be operated together. When the frame is of sheet metal, its edges are bent over so as to avoid injuring the vellum. In the case shown, the hooks F pass through lugs E on the frame, which have recesses to receive the tightening-nuts G. The frame may have a flange H to support the neck, but the principal attachment for the neck consists of a bolt I passing through the body. The bolt, which may be replaced by a wooden dowel, is applicable where the back is closed, but where the inside of the body can be reached, a screw applied from the inside may be used. The stringing is the same as that of a mandolin. The strings may be attached directly to the ring N, or may pass through holes in the ring and be attached to pins projecting from the body. The bridge L reaches entirely across the head. In a modified construction, a strengthening- strut is applied inside the body, and a plate is pressed upon the strings, between the bridge and their attachments, by bolts which pass through the head and engage with the back. These bolts act as sound-posts. The body is provided with sound holes.
