mercial, construction, institutional and industrial markets. It was Joseph Brad- ford Sargent, entering into this world in 1822, who formed the beginnings of SARGENT as we know it today, way back in 1884. Figure 43 A SARGENT Salute SARGENT’s pins and pin kits are numer- ous. They span many years from the cre- ation of the Conventional 437C pin kit to the innovative 437DGM Pin Kit for the SARGENT Degree Key System. Figure 41 shows these pin kits. Square Pin in a Round Hole? No, not exactly, but it’s one of the more novel pin types out there. It is known as the SARGENT square pin, circa early 1900s. It does sound counterintuitive to have a functional "square pin" in a lock- ing device, but it worked! The pins are stepped in a similar way to master wafers in a cam lock. It was invented to elimi- nate the use of split pin masters, making it more pick resistant. This was accom- plished by having two steps in each pin with a right hand blade change key and a leſt hand blade master key. Per Billy Ed- wards, CML, they were used in churches in New England (allegedly only Roman Catholic ones). As you can see from Figure 42 (cour- tesy of Arnold Saintnicholas), the five chamber holes are square, as are the pins. However, the 5-pin key appears to have only "traditional" wear. Who would have thunk it? SARGENT Signature 437S Pin Kit The 437S is the preferred kit (11" x 8.25" x 2") for those also pinning SARGENT con- ventional cylinders, as well as the SAR- GENT Signature and the SARGENT XC line. Consider it a 3-in-1 pin kit (Figures 43-44). WWW.ALOA.ORG Figure 42. As you can see here, the five chamber holes are square, as are the pins. SARGENT Degree DGM This is the premiere SARGENT Degree master kit (quite large at 16" x 12.5" x 2") for those pinning not only the De- gree DG1 cylinders and cores, but also the security DG2 and high security DG3 (rotating/angled pins, similar to Biaxial Original) cylinders. Plenty to play with in this kit (Figures 45-46). SARGENT Mini DUR-X LMDSGT We mustn’t forget the smaller SARGENT kit for those who may only pin an occa- sional SARGENT conventional cylinder from time to time. Ten bottom pins, 8 master pins, and 5 drivers reside in this quaint home alongside the snuggled cyl- inder springs (Figure 47). Tubular Yep, it’s the lock cylinder that’s designed with the pin tumblers in a circle, not in a straight line. The patent was established in 1935 for the first ACE tubular lock, the pattern for most of those that fol- lowed (Figure 48). Usually, seven pins are arranged in a circular pattern, and the corresponding key is also tubular or cylindrical in shape. It wasn’t until 1985 that the ACE II was created, and it’s still in use today. Figure 44 Figures 43-44. The 437S is the preferred kit for those also pinning SARGENT conven- tional cylinders, as well as the SARGENT Signature and the SARGENT XC line. Figure 45 Figure 46 Figures 45-46. The SARGENT Degree DGM is the premiere SARGENT Degree master kit for those pinning not only the Degree DG1 cylinders and cores, but the security DG2 and high security DG3 (rotating/angled pins, similar to Biaxial Original) cylinders.
