Publication number: 20240100609Abstract: A holesaw system comprises a holesaw including a base and a generally cylindrical wall with a proximal end coupled to the base and a distal end with a cutting edge; a pilot drill bit including a front cutting tip, a rear shank portion, and an intermediate portion between the front cutting tip and the rear shank portion; and an arbor coupleable to the holesaw and to the pilot drill bit. The arbor is configured to be operable in a first mode in which the holesaw and the pilot drill bit are rotatable in unison to form a hole in a workpiece and in a second mode in which the pilot drill bit is rotatable independently of the holesaw to remove a plug of material from the holesaw.Type: ApplicationFiled: September 21, 2023Publication date: March 28, 2024Inventors: Poinon Z. SANOGO, Marco LOURENCO, Jackson Mead BRANDIN, Andrew C. REIST, Joseph T.

Patent number: 9744604Abstract: A hacksaw with an improved mechanism for applying and adjusting the tension on a blade mounted to a blade mount on a front arm and a blade mount on a rocker arm. The rocker arm is pivotally coupled to a handle and is spring biased to place an initial tension on a blade held by the rocker arm and the front arm. A rotatably mounted lever is positioned on the handle for vertically displacing a nut captured in the rocker arm to pivot the rocker arm and adjust the tension on the rocker arm-held blade. An elongate top frame bar of the hacksaw defines a hollow I-beam cross-section accessible from the face of the front handle and is capable of storing saw blades. A bale screw is positioned in the front member for securing the blades in a position extending past the front handle.Type: GrantFiled: November 11, 2014Date of Patent: August 29, 2017Assignee: IRWIN INDUSTRIAL TOOL COMPANYInventors: Matthew C Green, Joseph Novak, Peter Weremchuk

Patent number: 9463516Abstract: A tensioning mechanism for a hack saw blade extends through a pin holder mounting slot of a hack saw frame and applies tension to a hack saw blade attached thereto. The tensioning mechanism includes a first portion having a configuration that, with respect to a configuration of the slot, permits rotation of the tensioning mechanism when the first portion extends through the mounting slot. The tensioning mechanism also includes a second portion having a configuration that, with respect to the configuration of the slot, engages into the slot only in select rotational orientations thereof relative to the slot, wherein one of said orientations is angularly separated from another orientation by a substantially set rotational angle of the second portion. The tensioning mechanism further includes first and second mechanisms configured to prevent removal of the tensioning mechanism from the mounting slot once extended therethrough.Type: GrantFiled: March 14, 2013Date of Patent: October 11, 2016Assignee: Irwin Industrial Tool CompanyInventors: Matthew C. Green, Christopher F. Fitzgerald

Patent number: 9358625Abstract: A hack saw comprises a proximal end, a proximal handle located at the proximal end, and a distal end spaced from the proximal handle for mounting a hack saw blade therebetween. The handle includes a proximal cavity at a base end thereof, dimensioned to allow a portion of a proximal pin holder therethrough, and a proximal pin holder retaining member within the proximal handle proximally spaced from the proximal cavity, defining a slot therebetween for retention of a pin holder therein. The pin holder retaining member is positioned to form an interference with the proximal pin holder when the pin holder is located in the handle and prevents the proximal pin holder from dislodging or being removed therefrom.Type: GrantFiled: March 14, 2013Date of Patent: June 7, 2016Assignee: Irwin Industrial Tool CompanyInventor: Matthew C.

Patent number: 9205551Abstract: A device for storage and transfer of tools and supplies that includes a housing, a cover and a handle. The housing defines a storage area therein and is configured to receive a plurality of tools and supplies. The cover is pivotally attached to the housing and is movable between a closed position covering the storage area and any tools and supplies therein, and an open position at least partially exposing and permitting access to the storage area and any tools and supplies therein. The handle is pivotally attached to the housing and is movable between a storage position located within the housing and a use position projecting from the housing for carrying the device thereby. The cover is movable between the closed and open positions while the handle is either in the storage position or the use position.Type: GrantFiled: March 14, 2014Date of Patent: December 8, 2015Assignee: Irwin Industrial Tool CompanyInventors: Matthew C.

Patent number: 9067313Abstract: A kit for carrying hole saws has a hole saw carrier configured to releasably carry thereon a plurality of nested hole saws, and is movable between (i) a storage position and (ii) a use position for removing one or more hole saws therefrom. The carrier is axially-elongated and receivable through an arbor hole in a hole saw to releasably carry the hole saw thereon and to allow one hole saw to be nested within another thereon. The carrier is pivotally mounted and movable between the storage and use positions.Type: GrantFiled: February 11, 2014Date of Patent: June 30, 2015Assignee: Irwin Industrial Tool CompanyInventors: Matthew C.
