Disclosed herein is a dynamometer control for a dynamometer including a control field coil and an air gap, which dynamometer control includes a main current line connected to the control field coil and including an electronic switch, means for generating a crossing signal incident to a sinusoidal crossing associated with current flow in the main line, and a micro-processor connected to the crossing signal generating means and to the electronic switch and including a counter which is operable to count between a given count and a zero count at a given counting rate, which includes means for adjusting the given count to provide an adjusted given count, which is operable, when the count is zero, to render the counter inoperable and to output a signal which turns on the electronic switch so as to provide current flow to the control field coil of the dynamometer until the counter is again activated, and which is operable, in response to receipt of the crossing signal, to activate the counter, to load the counter with the adjusted given count, to decrement the counter from the adjusted given count to the zero count at the counting rate, and to turn off the electronic switch so as to halt current flow to the control field coil of the dynamometer until arrival at the zero count, whereby the control field coil is deenergized for a time period determined by the adjusted given count.

A machine for connecting successive rows of coil springs together into a coil spring assembly. The machine, in preferred form, initially picks up a row of coil springs by inserting a pick up finger into the barrel of each coil and moving the springs onto a support platen. In the course of transporting the coils between pick up and the support platen, the pick up fingers change the spacing of the coils. The springs are then compressed against the support platen to a desired height through use of a reciprocable compression bar. Thereafter, and through use of rotatable transfer fingers on a transfer shaft, the springs are removed from under the compression bar, and are moved into clamping dies. Leading rotary transfer fingers on the transfer shaft first pull the row of springs out from under the compression bar, and trailing rotary fingers then push the springs into the downstream one of upper and lower clamping dies. If a leading row of coil springs are already present in the clamping dies, the rows of clamping dies clamp together the upper and lower end loops of the leading and trailing rows of coil springs.

Disclosed herein is a mechanism adapted for twisting an eye formed at one end of a U-shaped link, said mechanism comprising a frame, an input shaft supported by the frame for rotation and adapted to be rotated by a power source, a clamp on the frame for gripping the link against movement and with the eye extending from the clamp, and a rotatable head on the frame and connected to the input shaft and engagable with the extending eye for twisting the eye in one direction through a first angular distance in response to one portion of the rotational cycle of the input shaft and for additionally twisting the eye in the one direction through an additional angular distance in response to another portion of the rotational cycle of the input shaft. Also disclosed herein is a wire chain and a wire fabric and methods of making the same incorporating the operation of the above disclosed eye twisting mechanism.

A single continuous length of spring wire is formed into a continuous length spiral or helix which is subsequently folded into a wave configuration for establishing in row form, a plurality of individual spring coils disposed generally parallel one to another. Each coil in the row is connected at its opposite ends to adjacent coils by head or connector end sections. The head or connector end sections are then formed, preferably into a planar Z-shaped configuration such that the formed connector sections at the same ends of the coils are disposed in a common plane normal to the axes of the coils which they interconnect. During forming of the end sections or heads of the coils, each connector section is deformed from a looped three-dimensional attitude into the planar Z-shaped attitude by interengagement with novel forming pins and forming dies.

The machine initially picks up a row of coil springs by inserting a pick up finger into the barrel of each coil and moving the springs onto a support platen. While transporting the coils, the pick up fingers change the spacing of the coils. The springs are then compressed against the support platen to a desired height through use of a reciprocable compression bar. Thereafter, rotatable transfer fingers remove the springs from under the compression bar, and move them into clamping dies. Leading rotary transfer fingers on the transfer shaft first pull the row of springs out from under the compression bar, and trailing rotary fingers then push the springs into the downstream one of upper and lower clamping dies. The rows of clamping dies clamp together the upper and lower end loops of the leading and trailing rows of coil springs. The rows of springs are then connected together by helical lacing wires while clamped between the clamping dies.
