Abstract: A carafe having a thermal filler, a housing, and a sealant between the filler and housing. The housing has a top with an annular groove facing a bottom of the housing. The groove has an angled surface between an interior side of the groove and the top of the groove. A neck of the thermal filler is located in the groove with the sealant in the groove forming a seal between the housing and filler.

Abstract: A utility box for storing and/or carrying articles to a remote site has a base and a cover with a clamping vise incorporated as an integral portion of the cover. The base is a box-like structure defining a chamber for holding the articles and having a set of four pedestals which provide a supporting structure for the integral vise. The base further includes an integral pair of clamping feet which extend from two of the pedestals to form a surface which can be used to clamp the utility box to a relatively stationary surface. The cover is hingedly secured to the base and mates with a positioning rib extending from the base in order to locate and position the cover with respect to the base. The integral vise defines a worksurface and includes a stationary jaw and a movable jaw. The movable jaw is movable via a pair of threaded rods which are rotatably mounted to the cover.

Abstract: In a housing (22) for a right-angle grinder (20), a pair of clamshell sections (24) and (26) are joined along a midplane (28). The interior of the housing (22) is formed with a motor case (34) and a gear case (36). Clamshell section (26) is formed with a rib (76) in a peripheral edge (72) thereof and is nested in a groove (58) formed in a peripheral edge (56) of clamshell section (24) to form an interlock for the housing (22). Slots (78) and (80) are formed transversely through the rib (76) along two spaced paths of the interlock to preclude a flowable lubricating substance from creeping from gear case (36), along the two spaced paths of the interlock to the motor case (34).

Abstract: An improved power lawn rake has a rotor provided with a plurality of ground-engaging spring tines. The dead leaves and other debris are carried by the rotor along the curved forward wall of a deflector box, and are discharged between the deflector box and a front channel and into a molded bin. The bin is removably mounted on respective side housings of the main frame of the power lawn rake. Ground-engaging forward wheels are vertically adjustable on brackets mounted on the front channel. The wheels are nested within externally-accessible recesses formed in the bin. A driving motor is cantilever mounted on one of the side housings of the frame for driving the rotor. The drive is through gearing (in a gear case secured to the motor housing) and through a belt and pulley arrangement accessible through a cover plate removably secured to the side housing.

Abstract: A turbine-driven sander includes a minimum of one-piece sealed housing members so interconnected as to form a nozzle, a turbine chamber, and a valve chamber. A plurality of elongated support members are integrally formed on a housing member. Fasteners are inserted in the elongated support members to clamp the housing members together. A flap valve mounted in the valve chamber opens the turbine chamber to a source of vacuum, thereby driving a turbine rotatably mounted in the turbine chamber. This rotation in turn vibrates a platen through a direct-drive system. The platen is supported upon one of the housing members by two platen support members. A noise attenuation system at the front end of the housing includes a two-passage nozzle which is curved to interrupt the line of sight from a turbine air inlet to the turbine. A side branch resonator communicates with the nozzle via noise-attenuating holes in a cover plate located above the nozzle.

Abstract: A drive assembly for a chain saw (10) having a brake (42) wherein lugs (102) formed integrally on the brake drum (78) are mechanically connected within opening (72) of adjacent pairs of teeth (70) on the sprocket (22) which drives the saw chain (18) so that upon application of the brake (42) the brake drum (78) and the sprocket (22) stop simultaneously. The drive assembly includes a clutch (94) and a fastener (26) threadedly received on the drive shaft (24) to complete the assembly.

Abstract: A turbine-driven sander includes a nozzle, turbine chamber, and a valve chamber. A flap valve mounted in the valve chamber opens the turbine chamber to a source of vacuum, thereby driving a turbine rotatably mounted in the turbine chamber. This rotation in turn vibrates a platen through a direct-drive system. The platen is supported upon one of the housing members by a pair of platen support members, each member being temporarily connected to a metal plate to form a subassembly. Each platen support member is a molded plastic unit having a cross-member, a pair of snaps for engaging the metal plate, and a pair of flexible posts extending from each end of the cross-member. The support member is attached to a mating recess in the lower surface of a housing member. The flexible posts are attached to a platen.

Abstract: A portable power driven chain saw (20) having an automatic oiling system (54) including an externally adjustable control valve (60) which meters an adjustable flow of oil (69) therethrough unidirectionally and to stop the flow in the valve when the chain saw (20) is stopped. An improved oil pump (58) is provided of the rotor (72) vane type. The adjustable member (124) of the control valve (60) has a longitudinal opening (130) for the flow of oil (69) therethrough to the guide bar (24), also the opening (130) slidably carries the stem (144) of the check valve (140) which provides for the unidirectional flow.

Abstract: A shut-off device (104) controlling the operation of the motive means such as an electric motor which powers a tool such as a chain saw (12) having a housing (14) with a brake (34) therein operative to stop the chain saw (12). The shut-off device (104) includes a switch (54) biased off and shiftable on. A pivotable or shiftable trigger (72) is shifted toward but remains out of contact with the switch (54). A link (92) is caused to shift responsive to the brake (34) when the brake becomes operative, but the link is otherwise disposed intermediate the switch (54) and the trigger (72) to permit the trigger (72) movement to actuate the switch (54). However, on brake actuation the link is removed from a path of motion between the switch (54) and trigger (72) thereby to restore the switch (54) to "off" position. Once the link (92) is removed from the path of motion it cannot be reinserted therein until after the trigger (72) is released.

Abstract: An improved, portable, electrically energized surface finishing tool for use with peripherally acting finishing devices and for use with planar finishing devices is disclosed.
