Patent Summary

U.S. Patent Classes & Classifications Covered in this listing:

Class 123: Internal-Combustion Engines

Inventions relating to prime movers or engines in which a combustible material is burned within an inc losed space or chamber and the heat energy thus developed converted into work by permitting the resulting products of combustion to act upon and through mechanical powers, the engine in question including suitable mechanism whereby the functions above enumerated are continually and automatically carried out, and such engine being designed to communicate power to some machine or device exterior to itself. This class also includes separate parts of engines coming within the above definition and also subordinate elements designed for use with such engines, and incapable of use in the manner contemplated with other devices or in other relations.

Subclass 43A: Parallel to shaft
Subclass 43B: Toroidal cylinders

Class 417: Pumps

This is the general class for the pumping of fluids, and includes the pumping of slurries, fluent material and the like if handled in a manner not inconsistent with the handling of fluids. A pump is defined as means to move a fluid by taking it from one place or location and moving it to another place or location different from whence it came, the pump, therefore having an inlet and an outlet for the pumped fluid which are separate and distinct. The pumping of the fluid is generally accomplished by action thereon of a mechanical member (eg. piston) or by contact or entrainment with another fluid (eg. jet pumps). Also, the pumping may be accomplished by the direct action on the pumped fluid of an electric or magnetic. This class is the residual home for the formation of a vacuum in an enclosed space by a gettering action; a getter being a material which when placed in an enclosed space reduces the gas or vapor content of the space either by a chemical or physical action. Also, included are those devices and processes in which the fluid is ionized to permit or enhance the gettering action. These devices are often termed "getter-ion pumps".

Subclass 494: Having means to selectively effect control at different positions of pumping member stroke

Class 418: Rotary Expansible Chamber Devices

This class relates to devices which include a working chamber the volume of which is progressively variable into which fluid alternately enters and exhausts and which is formed by a surface (or surfaces) of a moving solid member having relative movement with another solid surface (or surfaces), a portion of the working chamber boundary being substantially fixed, and in which: (1) The working member has rotary motion in a single direction about a fixed or movable axis. (2) The working member is circular and causes a change in the volume of the working chamber as it is progressively tilted in a single direction about a point on its axis to progressively contact said other surface. (3) The working member causes a change in the volume of the working chamber but does not have absolute rotation.

Subclass 68: ROTATING INTERNAL MEMBER ROTATES AND OSCILLATES OR RECIPROCATES
Subclass 221: MOVING ABUTMENT AND VANE
Subclass 241: ABUTMENT OR VANE HAS CONCURRENT ROCKING AND RADIALLY SLIDING MOVEMENT

Class 91: Motors: Expansible Chamber Type

Motors for converting the energy of a pressure fluid into mechanical work in which a charge of simple pressure fluid is admitted to an expansible chamber, the expansion of said chamber converting into work only the original energy of the charge, the charge after expansion of said chamber being exhausted to some place other than whence it came, and in which no energy is extracted from the charge except by expansion of the chamber, said motors when of the reciprocating or oscillating type including control of the fluid.

Subclass 499: Cylinders parallel to rotation axis

Class 92: Expansible Chamber Devices

Devices which include an expansible chamber, said chamber having a wall portion thereof movable in a to and fro motion to vary the volume of the chamber, and having a fluid conducting passage means in communication with the chamber for introducing or withdrawing fluid therefrom. This class also takes miscellaneous sub-combinations of motors or pumps disclosed as being of the type having a chamber. This class excludes means to control the fluid to or from the chamber, except in the case of a sealing means for a working member which is adapted under certain conditions of operation to flex away from the encompassing chamber wall to allow fluid passage between said means and the chamber wall.

Subclass 179: Articulated connecting rod end forms portions of piston face
Subclass 256: Fastening means for parts include resilient element

Class 74: Machine Element Or Mechanism

Mechanical combinations, contrivances, or devices constituting portions of machines, instruments and apparatus and consisting of two or more fixed and movable parts so combined that the motion of one compels a completely controlled or constrained motion of the other according to a law of operation inherent in and depending on the nature of the combination, and also the elemental parts of such machines not provided for in other machine element classes.

Subclass 112: Rotary to intermittent unidirectional motion
Subclass 125.5: Intermittently engaged clutch
Subclass 63: Rotary to rotary

Class 192: Clutches And Power-Stop Control

Clutches, combinations including vortex flow drive and clutch, vortex flow drive and brake, clutch and brake, and clutch and gear; and also includes mechanism for joint control of transmission and clutch, and transmission and brake. This class includes the control of those various power-transmission means, motors, and brakes the motions of which occur at the completion of a cycle of operations or which are due to contact with the material handled by the machine or to the defective action of the parts of the machine operated or to such operations as arise from the initiation of measures for the safety of the operator.

Subclass 58.91: Vanes on inner member
