269  DF  THREE OR MORE CYLINDERS ARRANGED IN PARALLEL, RADIAL, OR CONICAL RELATIONSHIP WITH ROTARY TRANSMISSION AXIS {4}
273.~ Radial cylinders


DEFINITION

Classification: 417/273

(under subclass 269) Apparatus in which the longitudinal axes of said plural cylinders intersect at a common point from which they radiate and are contained within a common plane perpendicular to said axis of rotation.

(1) Note. In some instances, the longitudinal axes of the cylinders move relative to the axis of rotation and devices of this type are intended to be included hereunder if the individual cylinder axes pass through the common point in at least one position of their movement.

74, Machine Element or Mechanism, appropriate subclasses for mechanical motion converting apparatus having no pump fluid valving or parting claimed and see especially

55, for apparatus employing a cam and slide for converting rotary motion to or from reciprocating or oscillating motion.

91, Motors: Expansible Chamber Type,

491+, for three or more cylinders arranged in radial relationship with a rotary transmission axis which are generic to operation as either a pump or motor. 92, Expansible Chamber Devices, appropriate subclasses, for expansible chamber devices having plural radial cylinders in which there is no valving of pump fluid claimed and see especially

58, for plural rotating cylinders in which the axis of the cylinders intersect the rotation axis at a common point, subclasses 72+ for relatively movable working members interconnected with a common rotatable shaft and in which the shaft axis is intersected by the axis of the working members and subclass 148 for three or more unitarily mounted, radially arranged cylinders.
