Machinery for automated manufacture of formed wire structures such as innerspring assemblies for mattresses and seating and flexible support structures includes one or more coil formation devices configurable to produce generally helical spring coils having a terminal convolution which extends beyond an end of the coil; a conveyor system having a plurality of flights slidably mounted upon a continuous track and connected to a chain and driven by an index driver; a coil transfer machine which removes a row of coils from the conveyor and inserts the coils into an innerspring assembler; an innerspring assembler having first and second sets of coil-engaging dies in a parallel arrangement, each set of dies having an upper row positioned over a lower row, the dies being mounted upon carrier bars which are vertically translated within the innerspring assembler to diverge the upper and lower dies of a set to allow positioning of a row of uncompressed coils between the upper and lower dies, and to converge the upper and lower dies upon a row of coils to compress and thereby securely hold the coils in a row; a coil interconnection device for interconnecting adjacent rows of coils in the first and second sets of dies by attachment of fastening means about the adjacent coils; and an indexer assembly engageable with the carrier bars and operative to laterally translate the carrier bars, whereby the lateral position of the first and second sets of dies can be exchanged to provide continuous attachment of rows of coils to produce an interconnected array of coils as an innerspring assembly.

An instrument for obtaining tissue samples from a site deep within the body. The instrument has an elongated proximal portion that is constructed to follow a long, torturous path to the site and has a distal end constructed to sever and remove a tissue sample from the body, including tissue specimens, polyps or the like. The instrument is constructed to take multiple biopsy samples without being withdrawn from the body. The instrument includes a tissue sample retractor. The retractor is axially movable between an extended tissue-engaging position and a retracted position. There is an open passage into which the retractor moves when moving from the extended to the retracted position. The retractor has a distal end portion constructed to engage tissue and apply axial transporting force thereto while moving from the extended to the retracted position. The retractor is constructed to be advanced and retracted repeatedly to accumulate a series of samples in the instrument.

A compact, 4-chamber gas meter comprising crankpost and valve drive mechanisms whereby each reciprocating valve moves from a stroke shifting point near center to a stroke endpoint and back to said stroke shifting point with each 180.degree. rotation of the crankpost and each stroke of each diaphragm occurs over said 180.degree. rotation of the crankpost.
