20110107608 | RECIPROCATING SAW - A reciprocating saw includes a housing assembly and a motor positioned substantially within the housing assembly. The motor includes a pinion. A drive mechanism is positioned substantially within the housing assembly and includes a gear driven by the pinion, a spindle, and a connecting rod to transmit rotation of the gear into reciprocation of the spindle. A bushing is positioned substantially within the housing assembly about at least a portion of the spindle. The bushing is pivotable relative to the housing assembly to accommodate non-linear rocking motion of the spindle. A seal surrounds a portion of the bushing and includes a first lip extending radially from the bushing and a second lip spaced apart from the first lip and extending radially from the bushing. The second lip is movable relative to the first lip. Both the first lip and the second lip continuously engage the housing assembly when the bushing pivots relative to the housing assembly. | 05-12-2011 |
20130014968 | MOTOR MOUNT FOR A POWER TOOL - A power tool includes a motor having a can and a shaft extending axially from the can, a gear case having an inner surface that defines an opening, a bearing positioned around a portion of the shaft that extends from the can and at least partially within the opening in the gear case, and a motor mount coupled to the motor. The motor mount includes a flange extending away from the motor. The flange of the motor mount and the inner surface of the gear case axially and laterally locate the motor and the gear case on the bearing. | 01-17-2013 |
20130153253 | ROTARY HAMMER - A rotary hammer includes a motor, a spindle coupled to the motor for receiving torque from the motor, a piston at least partially received within the spindle for reciprocation therein, a striker received within the spindle for reciprocation in response to reciprocation of the piston, and an anvil received within the spindle and positioned between the striker and a tool bit. The rotary hammer also includes a retainer received within the spindle for selectively securing the striker in an idle position in which it is inhibited from reciprocating within the spindle, and an O-ring positioned between the retainer and the spindle. The O-ring is disposed around an outer peripheral surface of the anvil. The O-ring is compressible in response to the striker assuming the idle position. The compressed O-ring imparts a frictional force on the outer peripheral surface of the anvil to decelerate the anvil. | 06-20-2013 |
20140116739 | ROTARY HAMMER - A rotary hammer includes a motor, a spindle coupled to the motor for receiving torque from the motor, a piston at least partially received within the spindle for reciprocation therein, a striker received within the spindle for reciprocation in response to reciprocation of the piston, and an anvil received within the spindle and positioned between the striker and a tool bit. The rotary hammer also includes a retainer received within the spindle for selectively securing the striker in an idle position in which it is inhibited from reciprocating within the spindle, and an O-ring positioned between the retainer and the spindle. The O-ring is disposed around an outer peripheral surface of the anvil. The O-ring is compressible in response to the striker assuming the idle position. The compressed O-ring imparts a frictional force on the outer peripheral surface of the anvil to decelerate the anvil. | 05-01-2014 |

20090049869 | Thermal Protection Sleeve With Knit Thermal Protection Features And Method Of Construction Thereof - A knit protective sleeve and method of construction thereof provides a continuous and seamless sleeve wall knit from one or more yarns extending between opposite open ends of the sleeve. At least one heat vent opening is integrally knit within the wall between the ends. | 02-26-2009 |
20100084825 | TEXTILE GASKET AND METHOD OF CONSTRUCTION THEREOF - A textile gasket and method of construction thereof for establishing a seal between mating members in a high temperature application is provided. The gasket has a knit, tubular body constructed at least in part of non-metallic, heat-resistant yarns. The body extends between opposite ends with at least one of the ends being rolled toward the other end to form a circumferentially extending rolled portion of a predetermined diameter for receipt between the mating members. | 04-08-2010 |
20110162126 | TRI-LAYER KNIT FABRIC, THERMAL PROTECTIVE MEMBERS FORMED THEREFROM AND METHODS OF CONSTRUCTION THEREOF - A knit fabric, protective sleeve and glove constructed therefrom has three knit layers knit constructed and knit to one another in a single knitting operation to provide the fabric as a single piece of knit material. The fabric includes an outer layer, an inner layer and an intermediate layer sandwiched between the outer and inner layers. The outer layer is knit with a first yarn, the inner layer is knit with a second yarn and the intermediate layer is knit with a third yarn in looped fashion about at least some of the first and second yarns to provide an integrally knit structure having three layers knit stitched together in a single knitting process. | 07-07-2011 |
20130040081 | MULTILAYER TEXTILE SLEEVE AND METHOD OF CONSTRUCTION THEREOF - A multilayer textile sleeve and method of construction thereof is provided. The sleeve includes a textile wall having opposite edges extending lengthwise along a longitudinal axis of the sleeve between opposite ends. The opposite edges are configured to overlap one another to bound a central cavity of the sleeve. The wall has an inner layer with opposite inner and outer faces and an outer layer with opposite inner and outer faces. The inner and outer layers overlap one another and are constructed of interlinked yarn. The inner and outer layers are integrally connected to one another across interlinked portions adjacent the opposite edges by yarn common to each of the inner and outer layers. | 02-14-2013 |
20130224408 | KNIT SLEEVE FOR AN OIL DIP STICK TUBE, COMBINATION THEREOF, METHOD OF CONSTRUCTION THEREOF AND METHOD OF DAMPENING THE VIBRATION OF AN OIL DIP STICK TUBE - A knit sleeve for an oil dip stick tube, combination thereof, method of construction thereof and method of dampening the vibration of an oil dip stick tube is provided. The knit sleeve includes a circumferentially continuous, closed knit tubular wall extending between opposite ends with a pair of end sections adjacent the opposite ends and a midsection extending between the end sections. The end sections include heat-shrinkable yarn to allow the end sections to be heat-shrunk into a fixed relation about the oil dip stick tube. The midsection includes generally rigid, circumferentially extending, non-heat-shrinkable yarn to maintain the midsection having a circular configuration about the oil dip stick tube with an annular gap extending between the oil dip stick tube and an inner surface of the midsection. | 08-29-2013 |
20140273699 | Warp Knit Wrappable Sleeve With Extendable Electro-Functional Yarns and Method of Construction Thereof - A wrappable knit textile sleeve and method of construction thereof are provided. The sleeve includes a wall of knit yarn having opposite edges extending lengthwise along a longitudinal axis of the sleeve between opposite ends with a straightened length of the wall spanning between the opposite ends. The knit yarn includes warp yarns extending generally parallel to the longitudinal axis and weft yarns extending generally transversely to the longitudinal axis. The opposite edges are wrappable into overlapping one another to form a tubular cavity. At least one of the weft yarns is an electro-functional yarn having a straightened length that is greater than the straightened length of the wall, thereby allowing opposite ends of the at least one electro-functional member to be pulled axially outwardly from the opposite ends of the wall to form leads for attachment to a power source. | 09-18-2014 |
20150056881 | WRAPPABLE MULTI-LAYER HEAT SHIELD - A flexible, wrappable multilayered heat shield is provided. The heat shield includes a reflective metal outermost layer, an innermost layer of high temperature yarn capable of withstanding temperatures up to about | 02-26-2015 |
