Patent number: 7372210Abstract: A lamp drive circuit includes an electronic switch in series with the lamp and a source of DC voltage, a control input of the switch being pulse-width-modulated by a control circuit which includes a temperature-sensing circuit for reducing the pulse-width-modulation duty cycle when lamp temperature exceeds a predetermined temperature. The temperature-sensing circuit may include a thermal switch in series with one of two parallel-connected resistors in a timing circuit. Duty cycle may also be automatically adjusted in response to changes in the source voltage.Type: GrantFiled: October 1, 2003Date of Patent: May 13, 2008Assignee: Snap-on IncorporatedInventors: Martin S. Scolaro, Anil P. Ghode

Patent number: 7152695Abstract: A power tool is provided including a resilient boot having a radial flange mounted in a seat formed by housing halves in order to provide a sealed barrier segregating air of an inlet vent of a motor from air of an exhaust vent and the boot also mounting the motor and providing vibration dampening between the motor and the housing halves. The boot and housing also include wire management slots and the boot absorbs tolerance stack-up of components and provides shock absorption when the power tool is dropped.Type: GrantFiled: September 20, 2002Date of Patent: December 26, 2006Assignee: Snap-on IncorporatedInventors: Kenneth C. Happ, Anil P. Ghode, Ray D. Derome, Martin S. Scolaro

Patent number: 6043575Abstract: A power tool is provided and includes a tool housing having interior and exterior surfaces and inlet and outlet air vents and a motor disposed in the tool housing and having a motor housing with an external surface and inlet air ports for the passage of cooling air into the motor and outlet air ports for passage of warmed exhaust air from the motor. The inlet and outlet air ports open at the external surface and the outlet air ports are spaced from the inlet air ports. The tool also includes an air deflector resiliently coupled to the external surface. The air deflector includes wall structures bracketing the outlet air ports. The structures have portions extending to and contacting the interior surface of the tool housing and bracketing the outlet air vents to form a barrier around the outlet air ports and vents to channel exhaust air to the outlet vents and substantially inhibit exhaust air from the outlet air ports from entering the inlet air ports or other portions of the tool.Type: GrantFiled: March 5, 1999Date of Patent: March 28, 2000Assignee: Snap-on Tools CompanyInventors: Anil P. Ghode, Martin S. Scolaro, Raymond D. DeRome

Patent number: 5603393Abstract: A ratchet head assembly has a reversing knob with a metal shaft coupled to the pawl assembly of the ratchet mechanism and an enlarged-diameter plastic head insert molded around the outer end of the shaft and having a diameter two to three times that of the shaft and a density no greater than about one-fifth that of the shaft. Thus, the reversing knob has a low inertia so that it is not susceptible to self-reversing or self-locking during operation of the ratchet mechanism.Type: GrantFiled: October 12, 1993Date of Patent: February 18, 1997Assignee: Snap-on Technologies, Inc.Inventors: Anil P. Ghode, Martin S. Scolaro

Patent number: 5496139Abstract: An improved collet lock arrangement for a hand-held power tool having a housing is provided. The collet lock arrangement includes a powered rotatable shaft including a base portion and distal end portion defining a collet for adaptably connecting a driver tool attachment thereto and a locking structure for securely locking the shaft to the housing to selectively prevent the shaft from rotating when in a locked position while allowing the shaft to freely rotate in an unlocked position. The locking structure has a locking sleeve coaxially coupled around the shaft for axial movement relative thereto between the locked and unlocked positions, a clamp nut fixedly connected to the housing, and a sleeve guide non-rotatably coupling the locking sleeve to the clamp nut. The clamp nut and sleeve guide are coaxially arranged for coaxially receiving therethrough the shaft and the locking sleeve.Type: GrantFiled: September 19, 1994Date of Patent: March 5, 1996Assignee: Snap-on IncorporatedInventors: Anil P. Ghode, Martin S. Scolaro, Gordon A. Putney, Steven R. Wente

Patent number: 5237885Abstract: The tool includes a housing having two substantially semi-cylindrical members. An air motor in the housing has motor end members located adjacent each end thereof. Two O-rings, respectively disposed between the motor and the end members, are squeezable axially so as to be forced radially outwardly to abut the housing. A manifold includes a chamber of a size that dampens Helmholtz frequencies in the exhaust air. A bearing block includes an outer surface configured to transfer operating loads from a crank shaft extending through the bearing block to the housing. Each of the members of the housing has an arm with a cylindrical opening for receiving a rotatable drive body. The drive body has a knob including a shaft having an ear cooperating with an O-ring in the drive body for preventing the knob from inadvertently rotating between operating positions while the tool is in use. An O-ring between the knob and the drive body isolates the housing from shock to the knob resulting when the tool is dropped.Type: GrantFiled: July 21, 1992Date of Patent: August 24, 1993Assignee: Snap-on Tools CorporationInventors: Gordon A. Putney, Martin S. Scolaro, Kenneth C. Happ
