摘要： A socket, which receives a tool having a cylindrical shaft and which is mounted for rotation to rotate the tool, has an outer sleeve which receives a clamping sleeve and a ram for engaging a first end of the clamping sleeve. The first end of the clamping sleeve is provided with slots defining resilient tongues which are moved from a clamping position radially outward to a position for releasing the shaft by engagement with the ram. The ram has either an outer conically tapered surface or partially conically outer tapered surfaces on projections which engage inner tapered surfaces of each of the tongues or fingers. Preferably, the tapers of the ram and fingers are selected so that only substantially a line contact is formed therebetween to reduce the force necessary to move the fingers or tongues radially outward to the declamping or disengaging position.

摘要： A ball catch coupling for releasably connecting two parts which permits relative rotation of the parts in the connected conditions as an annular section carried on one of the parts with a number of uniformly disposed bores at a periphery thereof, balls respectively received and rotatable in each of the bores, a closed resilient ring surrounding the balls, an annular groove in the annular section which receives the ring and permits limited axial displacement and free rotation thereof within said groove, and the other part to be connected having an annular groove which at least partially receives the ring and the balls when the two parts are connected. The limited displacement and free rotation of the ring with respect to the annular section permits engagement and disengagement to be undertaken particularly easily and with low wear.

摘要： An apparatus for connecting a testing electrode to a source of electrical energy having a housing for receiving a testing electrode and a member for connecting the testing electrode to a source of electrical energy. The invention is particularly characterized by contact means disposed about a common line, which face each other, and which are spaced apart by spring means, the arrangement being such that contact between the contact means of said housing and the contact means of said member can be effected by relative displacement of said housing and said member in the direction of said common line or by relative tilting of said housing and said member in any direction.
