Plane stocks of cast iron
|
Hazard Knowles |
Colchester, CT |
This patent is the earliest American patent for a metallic plane, and it features prominently in both volumes of Roger K. Smith's books, "Patented Transitional and Metallic Planes in America."
According to Vol. I of PTAMPIA, "Apparently many other planemakers manufactured this type, either with or without license, because similar planes are known of various sizes and with minor design changes."
PTAMPIA Vol. II presents research relating to the manufacture of this design, including the fact that the known examples of the jointer plane also have Foster's patent 3,355 for a piece of soapstone inlet into the sole; in fact, Foster's patent, granted after this patent had already expired, shows a plane very similar to Knowles' design.
Several other Knowles patents were not restored after the 1836 patent-office fire: "Springs for carriages", 1825-11-04; "Mode of covering buildings", 1828-10-11; "Manufacturing wood screws", 1833-03-01; "Carriage to overcome obstruction in roads", 1833-08-29. |

Speed change pulley bracket support
|
Robert D. Phares |
Phoenix, AZ |
"This invention pertains to speed change pulley bracket supports for drill presses having frames with vertical columns supporting a drill head frame..." It provides a continuously variable speed mechanism using a pair of belts and a dual Reeves-style pulley. An example has been seen bearing a label, "Gilbert Engineering Co. / Phoenix, Arizona / Vari-Slo / Pat. 2,689,484 / Speed-Juster". Searching on "Speed-Juster" reveals that this design was also made by Savage Mfg. Co. of Phoenix, around 1951.
An article in the 1952-12-27 Arizona Republic mentions that Robert Phares was "general manager and chief designer" of Savage Mfg. Co., which had just introduced a new low-speed drill press attachment that cost less than $30. The idea came from Hal Savage of Arizona Welding Equipment Co., who originally intended to produce a new drill press with variable-speed drive. They also made a version for wood lathes and they developed a simplified unit for Sears, which was sold as the "Vari-Slo" variable-speed attachment for their 15" drill presses. Savage Mfg. Co. got into financial difficulty and was acquired by their landlord, Gilbert Engineering Co., who continued production until at least the late 1960s. |

Slow speed converter motor drive
|
Robert D. Phares |
Phoenix, AZ |
This is the patent for the Craftsman "Slo-Speed Converter" that was sold by Sears, Roebuck & Co. to convert a wood-cutting bandsaw to a metal-cutting saw. Every example we have seen is marked "PAT. PENDING". We have seen a couple of examples marked with the assignee's name, Savage Mfg. Co. That firm got into financial difficulty within a few years of this patent being issued, and this product's manufacture was taken over Savage Mfg.'s landlord, the Gilbert Engineering Co.
"This invention pertains to improvements in a slow speed converter motor drive applicable to electric drive motors for machine tools and other devices. ...easy to install...may be installed without any special machining or special brackets or fixtures or modification of the motor or machine...mounted on the drive shaft of the motor and supported by torque arms connectable to the mounting supports for the motor...readily shifted manually from a low speed drive to a high speed drive or vice versa with any special apparatus or skill..." |
