Abstract
Abstract A device for translating rotary motion of one member into linear motion of another. It includes a rotating member, such as a screw, which is removably engageable with a threaded partial nut. On engagement, screw rotation causes linear nut movement. This movement may be used to control motion of further devices.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
90 words
A device for converting rotary motion of one member into linear movement of another member, comprising: a traveling member movable only in a first linear direction, said traveling member including an interiorly threaded partial nut portion; a screw member positioned for rotational movement, said screw member having a threaded portion matingly engageable with said traveling member''s threaded portion; and means for causing linear motion of said screw member in a further direction perpendicular to said first direction thereby causing engagement and disengagement of said traveling and screw members'' threaded portions.
Claim 2
Independent Claim
90 words
A device for converting rotary motion of one member into linear movement of another member, comprising: a traveling member movable only in a first linear direction, said traveling member including an interiorly threaded partial nut portion; a screw member positioned for rotational movement, said screw member having a threaded portion matingly engageable with said traveling member''s threaded portion; and means for causing linear motion of said screw member in a further direction perpendicular to said first direction thereby causing engagement and disengagement of said traveling and screw members'' threaded portions.
Claim 3
Dependent Claim
21 words
The device of claim 1 and including means for causing oscillation of a yoke device on said traveling member moving linearly.
Claim 4
Dependent Claim
19 words
The device of claim 2 wherein said oscillation causing means includes a transverse pin carried by said traveling member.
Claim 5
Dependent Claim
37 words
The device of claim 1 wherein said screw member linear motion causing means includes a block portion rotatably receiving said screw member, and means for carrying said screw into and out of engagement with said partial nut.
Claim 6
Dependent Claim
17 words
The device of claim 4 wherein said engagement means includes a cam device engageable with said block.
Claim 7
Dependent Claim
45 words
The device of claim 4 wherein said engagement means includes a structure having a portion for passage therethrough of the shank of a fastener, and a fastener, said fastener having a head portion received by said block, and a shank passing through said passage portion.
Claim 8
Independent Claim
95 words
A device for actuating a valve comprising: Valve stem receiving means, said means including slotted arms; pin member received by said slotted arms, said pin member received by a linearly movable rod, said rod including a threaded partial nut portion; rotatable screw member having a threaded portion removably engageable with said partial nut portion, said screw member including means for causing rotation thereof; and means for causing movement of said screw member in a direction intersecting the direction of movement of said rod, thereby causing engagement and disengagement of said screw and partial nut portion.
Claim 9
Independent Claim
95 words
A device for actuating a valve comprising: Valve stem receiving means, said means including slotted arms; pin member received by said slotted arms, said pin member received by a linearly movable rod, said rod including a threaded partial nut portion; rotatable screw member having a threaded portion removably engageable with said partial nut portion, said screw member including means for causing rotation thereof; and means for causing movement of said screw member in a direction intersecting the direction of movement of said rod, thereby causing engagement and disengagement of said screw and partial nut portion.
