Publication number: 20230112745Abstract: An improved arcuate sweep elbow pipe connector section having an increased flow capacity and is a replacement for conventional ninety degree elbows as part of the piping system used to deliver water from a source to a fire sprinkler head. The arcuate sweep elbow pipe connector section is integrally formed at one end with a first connecting section and integrally formed at a section end with a second connection section. The connecting sections are positioned ninety degrees relative to each other and the arcuate sweep elbow pipe connector section optimizes water flow through both connecting sections.Type: ApplicationFiled: December 14, 2022Publication date: April 13, 2023Inventor: Douglas Swingley

Patent number: 11473694Abstract: A valve operator assembly may include a housing, a yoke, and one or more stoppers. The housing is mountable on a valve, and includes a body having a sidewall including a shaft bore, to receive a shaft rotatable within the housing, and a cover having a top member mountable on a top portion of the body and a side portion extending downwards adjacent to and partially overlapping the sidewall. The yoke is operably coupled by a yoke nut to the shaft to impart rotation to a valve stem of the valve when the shaft is rotated. The one or more stoppers are disposed within the housing to restrict the linear motion of the yoke nut.Type: GrantFiled: September 2, 2021Date of Patent: October 18, 2022Assignee: Spears Manufacturing Co.Inventors: Wayne Spears, David Glover, Douglas Swingley

Patent number: 8381655Abstract: A cartridge casing for rifles is made from a high strength aluminum alloy. A method for making such cartridge casing includes the steps of (a) forming a cylindrical blank from an aluminum alloy having a tensile strength greater than 80,000 psi, and (b) rotating the blank at a rate greater than 500 rpm and forcing the blank into a die, the die having a bore with progressively reduced interior diameters which are less than the external diameter of the blank. In the method, the forcing of the blank into the die results in the finished cartridge casing having a distal end with an external diameter which is less than the external diameter of its proximal end.Type: GrantFiled: March 28, 2012Date of Patent: February 26, 2013Assignee: Spears Manufacturing Co.Inventors: Douglas Swingley, Robert Wayne Spears, Scott Miller, Mehroujan Shirvanian

Patent number: 7426784Abstract: The invention satisfies this need. The invention is an internally threaded insert for use with a polymetric pipe fitting in a fire sprinkler system. The insert comprises an outer side surface, an outer rearward surface and an outer forward surface. The outer forward surface is adapted to retain a fire sprinkler at a forward end of the insert. The outer side surface of the insert is sized and dimensioned so as to closely match the bores of standard polymeric pipe fittings, so as to be capable of being slidably and snugly received into the bores of a standard polymeric pipe fitting. The insert can be conveniently affixed within the bores by non-mechanical means, such as by gluing.Type: GrantFiled: September 14, 2005Date of Patent: September 23, 2008Assignee: Spears Manufacturing Co.Inventors: Wayne Spears, Douglas Swingley

Publication number: 20050258650Abstract: A pressure fitting has a body with an internal bore of a specific nominal diameter. The internal bore is threaded with internal bore threads. The internal bore threads have sides, crests and roots. The sides are disposed at a specific angle ?. The roots are recessed such that, when an externally threaded pipe having (i) the same nominal diameter as the bore of the pressure fitting body, and (ii) external threads with sides disposed at the same specific angle ? and with sharp crests is disposed within the bore of the pressure fitting body, the sharp crests of the external threads do not impinge upon the roots of the internal threads.Type: ApplicationFiled: May 6, 2005Publication date: November 24, 2005Inventor: Douglas Swingley

Patent number: 6899127Abstract: A ball check valve comprises a valve body chamber which includes an inlet opening, an outlet opening, and a ball that is free to travel within the valve body chamber. A valve seat is adapted for receiving the ball. A body clearance section is located downstream of the inlet opening. A bore section is located downstream of the body clearance section. Fluid flow is allowed to flow through the valve body from the inlet opening through the outlet opening, but fluid flow through the valve body from the outlet opening through the inlet opening is prohibited by the interaction of the ball and the valve seat. The inlet opening is smoothly contoured to urge fluid flow between the inlet opening and the outlet opening to be laminar in nature.Type: GrantFiled: August 9, 2002Date of Patent: May 31, 2005Assignee: Spears Manufacturing Co.Inventor: Douglas Swingley
