Abstract
Abstract Apparatus for machining the end walls of slant axis rotary mechanisms including a base, a support pivoted on the base for rotation about a first axis, a shaft journalled on the support for rotation about a second axis nonparallel to the first axis, a work holder carried by the shaft for receiving a housing element of a slant axis rotary mechanism to have an end wall machined thereon, a tool adjacent the work holder operable to perform a machining operation on a housing element received on the work holder, a drive for rotating the shaft, and a mechanism responsive to the rotation of the shaft for oscillating the support about the first axis in timed relation to rotation of the shaft so that a housing element will be rotated and oscillated against the tool to machine an end wall thereon.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
167 words
Apparatus for machining the end walls of slant axis rotary mechanisms, comprising: a base; a support pivoted on said base for rotation in a single plane about a first axis; a shaft journalled on said support for rotation about a second axis nonparallel to said first axis and movable with said support in said single plane; a work holder carried by and rotatable with said shaft for receiving a housing element of a slant axis rotary mechanism to have an end wall machined thereon said work holder being shiftable with said shaft only in said single plane; means, including a tool adjacent said work holder operable to perform a machining operation on a housing element received on said work holder; means for rotating said shaft; and means responsive to rotation of said shaft for oscillating said support about said first axis in timed relation to rotation of said shaft, whereby a housing element will be rotated and oscillated against said tool to machine an end wall thereon.
Claim 2
Dependent Claim
167 words
Apparatus for machining the end walls of slant axis rotary mechanisms, comprising: a base; a support pivoted on said base for rotation in a single plane about a first axis; a shaft journalled on said support for rotation about a second axis nonparallel to said first axis and movable with said support in said single plane; a work holder carried by and rotatable with said shaft for receiving a housing element of a slant axis rotary mechanism to have an end wall machined thereon said work holder being shiftable with said shaft only in said single plane; means, including a tool adjacent said work holder operable to perform a machining operation on a housing element received on said work holder; means for rotating said shaft; and means responsive to rotation of said shaft for oscillating said support about said first axis in timed relation to rotation of said shaft, whereby a housing element will be rotated and oscillated against said tool to machine an end wall thereon.
Claim 3
Dependent Claim
16 words
The apparatus of claim 1 wherein said tool is mounted for reciprocation across said work holder.
Claim 4
Dependent Claim
24 words
The apparatus of claim 1 wherein said tool is a rotatable disc journalled for rotation about an axis substantially parallel to said first axis.
Claim 5
Dependent Claim
23 words
The apparatus of claim 3 wherein said oscillating means includes an oval shaped cam rotatable at the same angular velocity as said shaft.
Claim 6
Dependent Claim
13 words
The apparatus of claim 4 wherein said cam is carried by said shaft.
Claim 7
Dependent Claim
158 words
Apparatus for machining the end walls of slant axis rotary mechanisms, comprising: a base; a support pivoted on said base for rotation about a first axis; a shaft journalled on said support for rotation about a second axis nonparallel to said first axis; a work holder carried by said shaft for receiving a housing element of a slant axis rotary mechanism to have an end wall machined thereon; a cutting tool; means mounting said tool adjacent said work holder for reciprocation across said work holder to provide generally radially extending machine marks on an end wall received on said work holder; means for rotating said shaft; and cam means rotated by said shaft and engageable with cam following means supported by said base for oscillating said support about said first axis in timed relation to the rotation of said shaft, whereby a housing element will be rotated and oscillated against said tool to machine an end wall thereon.
Claim 8
Dependent Claim
158 words
Apparatus for machining the end walls of slant axis rotary mechanisms, comprising: a base; a support pivoted on said base for rotation about a first axis; a shaft journalled on said support for rotation about a second axis nonparallel to said first axis; a work holder carried by said shaft for receiving a housing element of a slant axis rotary mechanism to have an end wall machined thereon; a cutting tool; means mounting said tool adjacent said work holder for reciprocation across said work holder to provide generally radially extending machine marks on an end wall received on said work holder; means for rotating said shaft; and cam means rotated by said shaft and engageable with cam following means supported by said base for oscillating said support about said first axis in timed relation to the rotation of said shaft, whereby a housing element will be rotated and oscillated against said tool to machine an end wall thereon.
Claim 9
Dependent Claim
157 words
Apparatus for machining the end walls of slant axis rotary mechanisms, comprising: a base; a support pivoted on said base for rotation about a first axis; a shaft journalled on said support for rotation about a second axis nonparallel to said first axis; a work holder carried by said shaft for receiving a housing element of a slant axis rotary mechanism to have an end wall machined thereon; rotatable tool means adjacent said work holder and rotatable about a third axis parallel to said first axis to perform a machining operation on a housing element received on said work holder; means for rotating said shaft; and cam means rotated by said shaft and engageable with cam following means supported by said base for oscillating said support about said first axis in timed relation to the rotation of said shaft, whereby a housing element will be rotated and oscillated against said tool to machine an end wall thereon.
Claim 10
Dependent Claim
157 words
