A device for machining a plurality of workpieces. The device having a plurality of identical independent machining assemblies attached on a rotating carousel plate such that one operator can unload and load a workpiece at one machining assembly while the other machining assemblies are machining the workpiece therein such that when a machining assembly returns from rotation on the carousel plate it is finished machining.

A rotary vane machine includes a rotor having one or more sliding vanes. The rotor rotates within a chamber of a housing. At least one sealing plate is located between an end surface of the rotor and a corresponding inner surface of the housing. The sealing plate improves the seal between the rotor surface and the inner housing surface.

In a milling machine or the like having a socket for a removable arbor having, a frictional engaging member is positioned around the removable arbor such that the frictional engaging member is positioned between the removable arbor and the spindle when the arbor is inserted into the spindle. A flange is positioned below the clamping member on the removable arbor to limit the downward motion of the clamping member and to communicate with the spindle to limit the inward placement of the arbor within the spindle. A sleeve connects the arbor to a drawbar and a drive collar engages the arbor with the spindle for rotation.

A blade sharpener includes a handle to which first and second sharpening members are pivotally attached. The handle has first and second receiving slots for the first and second sharpening members, each slot being on a side opposite the other within the handle. The sharpening members are capable of pivoting from a slot engaging position to an upwardly inclined position, the upwardly inclined position being defined by engagement of a stop within the handle. The sharpening members are inclined in opposite directions resulting in their upper portions being in a spaced relationship. When the blade sharpener is not in use, the sharpening members are pivoted into their respective receiving slots forming a compact unit for storage.

The present invention relates to the construction of sports rackets, such as those used for tennis and similar games. The racket has weight means which moves transverse to the plane of the racket stringing, mounted adjacent to the bow or head of the racket to provide inertial rebound deadening when the racket strikes a ball.
