Patent Number	Date	Title	Name	City	Description
1,608,113	Nov. 23, 1926	Chuck	Axel G. Lundin	Brooklyn, NY
		Chuck	George E. Nace	Brooklyn, NY
2,159,162	May. 23, 1939	Tap Holder Chuck	Carl W. Johnson	Brooklyn, Kings County, NY	Claim: In devices of this type it is usually desirable to provide means which allow a tap, or other tool Sto be quickly inserted and removed from the chuck in order that a minimum of time may be consumed in change of tool. In prior devices it has been customary to use screw threaded members for adjusting the centralizing elements or gripping jaws which bear upon the shanks of these tools. It is obvious that with this kind of a structure it is not possible to effect an extremely rapid change of tool because of the necessity of screwing parts thereof into proper position.
2,237,875	Apr. 08, 1941	Chuck Jaw	Frederick R. Brown	Brooklyn, Kings County, NY	Claim: Primarily, the improved appliance constituting the subject of the present application may be regarded as an improvement upon the tap holder chuck disclosed in the application for Letters Patent, dated 29 July, 1936, of Carl W. Johnson, now Patent No. 2,159,162. issued 23 May, 1939, and the present invention is of special utility when embodied in a tool of that character, although it is capable of general employment where provision is required for effecting a positive and secure grip upon an attached part.
2,293,053	Aug. 18, 1942	Bandsaw bread-slicing machine	Lester Ferenci	Brooklyn, NY
2,552,580	May. 15, 1951	Vise having jaws supportable on flat surface of machine tool by spindle adjustable and lockable in plane parallel to said surface	Henry Persson	Miami, FL	This is the well-known Float-Lock vise, which (as of 2017) is still in production as the Wahlstrom Float Lock Drill Press Vise from Penn Tool Co., Inc.
RE23,519	Jul. 01, 1952	Vise having jaws supportable by flat surface of machine tool by spindle adjustable and lockable in plane parallel to said surface	Henry Persson	Bloomfield, NJ	This is the well-known Float-Lock vise, which (as of 2017) is still in production as the Wahlstrom Float Lock Drill Press Vise from Penn Tool Co., Inc.
2,724,295	Nov. 22, 1955	Quick change vise having having jaw supportable on flat surface of a machine tool and a spindle adjustable and lockable in plane parallel to said surface	Henry Persson	Bloomfield, NJ	This patent contains improvements to the Float-Lock vise of patent 2,552,580, which was reissued as 23,519.
2,798,757	Jul. 09, 1957	Article lifting device	John Jackson	Brooklyn, NY	"This invention... is more particularly designed for grasping, lifting and transferring groups of small variable sized articles, such as eggs." This device was manufactured by an egg handling equipment manufacturer, Precision Egg Equipment Co., doing business as PEECO. It was originally made under license from American Machine & Foundry Co. In 2014 PEECO was acquired by KUHL Corp., which plans to continue making this invention under the PEECO name.
2,854,613	Sep. 30, 1958	Motor control system	Jesse R. Mowery	Lancaster, PA	"This invention relates to motor control systems, and more particularly to improvements in systems in which an alternating current motor is dynamically braked by the application of D. C. to its windings."
D186,423	Oct. 20, 1959	Radial arm tool for sawing, planing or the like	Roger Protas	Pittsburgh, PA
		Radial arm tool for sawing, planing or the like	Anton Parisson	Brentwood, PA
2,926,709	Mar. 01, 1960	Guard for rotary power cutter	Robert C. Kaley	Landisville, PA	This patent number has been seen on both AMF and DeWalt radial arm saws.
2,942,632	Jun. 28, 1960	Locking structure for power tool setting	Harold C. Cassey	Landisville, PA
2,973,674	Mar. 07, 1961	Drilling fixture for spherical objects	Joseph Anton Hladik	Cicero, IL	This fixture holds a bowling drill for drilling the grip holes. An example bears the AMF logo plus this patent number and "Cat. No. 45-62-03".
3,212,649	Oct. 19, 1965	Machine for Performing Work	Harry T. Johnson	Glenview, Cook County, IL	Claim: A machine of the type described, comprising a base, a column mounted thereon for rotary movement about a vertical axis, a horizontal arm mounted on said column for vertical movement therealong and for movement along a horizontal axis perpendicular to said vertical axis, a wrist member mounted at an end of said arm for rotary movement about said horizontal axis and for swinging about a central vertical axis perpendicular thereto, a work manipulating member mounted on said wrist member for engaging and handling a work piece, a first hydraulic actuator including means coupled to said column for reciprocally rotating said column, a second hydraulic actuator including means coupled to said arm for raising and lowering said arm, a third hydraulic actuator including means coupled to said arm for reciprocally moving said arm along said horizontal axis, a fourth hydraulic actuator including means coupled to said wrist member for rotating said wrist member, a fifth hydraulic actuator including means coupled to said wrist member for swinging said wrist member, a sixth hydraulic member for operating said work manipulating member, a source of fluid under pressure, manipulating member, a source of fluid under pressure, conduit means connecting said source to each of said hydraulic actuators, servo-valve means associated with each of said actuators for controlling the flow of fluid thereto and electrical control means for operating said valve means separately or in combination.
