Abstract: A lock for safety belts having a lock housing secured to a surface of a vehicle and an inner housing slideably located in the lock housing and held therein by spring tension. The lock is also provided with a latch tongue, insertable into the inner housing, and with a latch positioned within the inner housing adapted to engage a depression in the latch tongue under spring loading, with the latch tongue insertable into the inner housing, preventing the withdrawal of the latch tongue therefrom. A release key located on the lock housing is operable from the outside thereof; and said lock further comprises a lever pivotable on a pivot comprising part of said lock housing and engaged by said release key.

Abstract: An apparatus for winding spring wire from a stationary supply spool into a helical or spiral spring. The apparatus is equipped with a rotationally driven winding mandrel having a forward end and being provided with a radial slot at its forward end for the reception of the spring wire. The mandrel is axially movable with the increasing length of a helical or spiral spring, from a withdrawn or forward initial position into a projecting final position. The apparatus further includes a transfer head, having a guide channel, positioned adjacent to the final position of the mandrel and with the guide channel in the transfer head coaxially aligned with the mandrel, for the passage of the spring therethrough. At least one roller compressively biased against the forward end of the mandrel in the final position thereof and is rotatable in a plane passing through the rotational axis of the mandrel; and the transfer head is driven coaxially and synchronously with the mandrel.
