(7.) In a machine of the class described, the combination of the following instrumentalities—namely, threading rolls or discs to act on the wire and form the threads thereon, a rotatable carrier for said threading-rolls, and means to deflect or bend the wire on its passage to the threading-rolls, comprising loosely mounted wheels or rolls arranged substantially in line with each other, substantially as described. (8.) In a machine of the class described, the combination of the following instrumentalities—namely, rotatable threading discs or rolls to act on the wire and form the threads thereon, a wire-deflecting- or bending-device to act on the unthreaded wire and cause the same on its movement toward the threading discs or rolls to travel in a path at an angle to the path in which the said wire is moved while under the action of the threading rolls or discs, and an oiling-device for the unthreaded wire with which said wire makes contact previous to its meeting the deflecting- or bending-device, substantially as described. (9.) In a machine of the class described, threading discs or rolls, supports for said rolls provided with oppositely inclined faces, discs secured to said oppositely inclined faces, studs or pins projecting beyond said discs and on which said rolls are loosely mounted, a cap or head on said studs or pins, and anti-friction bearings for the said threading-rolls interposed between said studs and said threading-rolls, and between the threading-rolls and the discs secured to the inclined faces, and between the cap or head on the studs or pins and said threading-rolls, substantially as described. (10.) In a machine of the class described, the combination of the following instrumentalities—namely, mechanism to act on wire and form threads thereon, and means to cause the wire on its passage to the threading-mechanism to move in a path at an angle to the path in which the wire is moved while under the action of the threading-mechanism, substantially as described. (11.) In a machine of the class described, the combination of the following instrumentalities—namely, mechanism to act on wire and form threads thereon, and means to bend the wire before its presentation to the threading-mechanism.
