Abstract:
A vise having a fixed jaw on a body which has a base secured to a work surface and may be rotated through 180.degree.. The body has a guide slot formed therein and a movable jaw is slidably received in the guide slot. A guide rod is disposed through an opening in the movable jaw and is threadably received in an upright lug secured to the base for movement of the movable jaw. A positioning nut is keyed to the threaded guide rod and secures the movable jaw to the guide rod. The vise has clamp claws on the inner and outer sides of the fixed and movable jaws so that the vise can exert force in both directions. The workpiece may be clamped between the inner side of the jaws and the jaws may be adjustably disposed within the workpiece to secure the workpiece about the outer side of the jaws. The end of the movable jaw which extends through the body has a notched slot therein and there is also a notched recess in the body of the vise. A workpiece may be disposed vertically in the notched slot and clamped against the notched recess in the body.
Abstract:
An apparatus is provided for controlling an electric motor that is doing some sort of work, whereby the apparatus automatically senses the presence of a work overload. Once the work overload is sensed, the apparatus automatically reverses the direction of rotation of the motor to eliminate the work overload. The reversed rotation is limited to either a predetermined period of time or to a predetermined number of reverse rotations. Once the predetermined limit of reverse rotation is reached, the apparatus automatically resumes normal rotation of the motor.
Abstract:
An internal combustion engine includes a set of gas chambers including a compression chamber for compressing a fuel/gas mixture and a combustion and exhaust chamber for combusting the fuel/gas mixture and for exhausting the waste gases. The compression chamber and the combustion and exhaust chamber are defined by a stationary wall and a moving wall. Means are provided for sequestering a portion of the gases in the compression chamber. The sequestering means are controlled by the position of the sequestering means with respect to the wall of the compression chamber. A transfer chamber saves the sequestering gases and releases the sequested gases into the combustion and exhaust chamber at a predetermined time in the engine cycle before the gases are exhausted from the engine. The gas sequestering and transfer means can be used in a rotary engine, a linear engine, and a reciprocating engine.
Abstract:
Disclosed is a lamination design for the stator of an electric motor, especially a two-pole single-phase induction motor. The stator lamination has a substantially elliptical configuration, and the circumferential spacing between the adjacent winding slots is greater at the minor axis of the ellipse than at the major axis thereof.
Abstract:
An internal combustion engine having as upper cylindrical gas chamber and a lower cylindrical gas chamber. The upper chamber having a bottom portion serving as the combustion chamber. A cooling jacket is provided between the two chambers to cool the sealing means therebetween. An inter-chamber passageway for direct communication between the bottom portion and lower chamber is provided.
Abstract:
An internal combustion engine having a bi-diameter or stepped piston configuration. The piston having a smaller upper piston portion and a larger lowre piston portion. A pumping chamber is formed in part by the larger lower piston portion separate from each of the crankcase and combustion chamber. Fluid reaches the pumping chamber from outside the pump/engine and is pumped-out beyond the pump/engine. The pumped fluid never communicates with either of the sealed crankcase or combustion chamber.
Abstract:
A two-cycle engine having upper and lower cylindrical gas chambers controlled by an inter-chamber passageway. The lower gas chamber acts as the combustion chamber. The upper gas chamber is divided into two parts by a piston wherein the lower portion of the upper chamber acts as a compression chamber for fuel and air introduced therein. The combustion products are expelled from the lower chamber via an exhaust port in a bottom part of the lower gas chamber.
Abstract:
A clamping device which includes a fixed member, a movable member and a threaded shaft passing through the members for pressing an object therebetween. A pressing head having external threads which are finer than the threads of the shaft is placed on the threaded shaft. A pressing cap having internal threads complementary to the threads of the pressing head surrounds the head. This cap provides stronger pressing power upon the object being clamped after the threaded shaft has been moved. A relatively small bolt head formation is formed on the threaded shaft and a relatively large fitting is formed on the pressing head. A handle is provided having a relatively small socket formed therein for being removably received on the relatively small bolt formation providing torque therefore, and a relatively large socket formed therein for being removably received on the relatively large fitting providing torque therefore.

Abstract:
It is an improved mechanism of vise; the feature of this invention is that on the two jaws of a vise, a sliding movable clamp piece is mounted for clamping a working piece having a plane surface, or irregular planes; in addition, said sliding movable clamp piece can automatically adjust its angular and eccentric sliding movement so as to tightly position a working piece on a vise.
