Patent number: 4080704Abstract: A method of making a multi-V-grooved sheet metal pulley from a flat sheet metal strip. The strip is passed through forming rolls which preform a plurality of generally V-shaped, transversely spaced, longitudinally extending grooves in a portion of the strip, and a generally flat hub wall flange in a transversely adjacent second portion of the strip. The hub wall flange portion of the strip then is notched to preshape the flange prior to circular forming the bottom hub wall of a pulley therefrom. The preformed grooved and notched strip then is severed into individual strips, each of which provides the material for a cup-shaped sheet metal pulley. Each strip then is passed between a pair of wrapping rolls which form the strip into a circular, preferably cylindrical configuration with the strip ends located adjacent to each other. The adjacent ends of the strip then are abutted and welded together, forming a cup-shaped pulley.Type: GrantFiled: January 26, 1977Date of Patent: March 28, 1978Assignee: Blakesley Pulley CorporationInventor: Roland F.

Patent number: 4080701Abstract: A simplified method for the fabrication of a fireplace water jacket, and the water jacket produced by the fabrication method. Each of several walls of a water jacket is formed from first and second metal plates. The first metal plate of each wall is disposed in a generally horizontal position on an orificed support, and a punch is brought into operative engagement therewith to punch a hole in the plate and simultaneously deform the area surrounding the hole so that the plane of the hole is spaced a given distance as from the plane of the plate. The first plate is then placed on the second plate so that the plates are generally parallel and so that the area surrounding the hole in the first plate abuts the second plate, and then the plates are secured together by welding around the area defining the hole in the first plate to the portion of the second plate visible through the hole in the first plate. The plates when joined together are spaced apart a distance S and water may circulate between the plates.Type: GrantFiled: March 31, 1977Date of Patent: March 28, 1978Assignee: Ridgway Steel Fabricators, Inc.Inventor: Clarence W.

Patent number: 4077559Abstract: This invention relates to apparatus for facilitating the construction of a heat exchanger, such as a condenser or evaporator employed in an air conditioning system, wherein exchanger tubes extending through a plate fin assembly are joined together by means of return bend connections or the like. The ends of the tube are provided with an oval shaped bell in which are telescoped the return bends. Diametrically opposed nibs are formed on the outer surface of the return bend connectors near the distal end thereof. The outside diameter over the nibs is slightly larger than the minor inside diameter of the oval bell. The nibs are inserted into the bell aligned along the minor diameter of the opening. The nibs are thus caused to ride in engagement against the wall of the bell to frictionally support the connector in assembly. The joint is then immersed in a molten solder bath whereby solder flows freely into the joint region along the major axis to create a highly reliable joint.Type: GrantFiled: September 27, 1976Date of Patent: March 7, 1978Assignee: Carrier CorporationInventor: James J.
