Abstract
Abstract Disclosed herein is a reciprocating drive mechanism and means for either amplifying or suppressing the output of the mechanism. The mechanism includes a rotating cam adjacent to which is positioned a carriage member having a cam follower mounted thereon. The carriage member acts as a housing for a pair of racks which have interengaging teeth and are preferably mounted perpendicular to each other. The carriage is mounted for translatory movement in response to the action of the cam and cam follower and the racks are forced into relative movement with respect to the carriage by a stationary elongated member. The elongated member has a track on one face thereof, in which is engaged a roller, the roller being mounted on the surface opposite the teeth of one of the racks. When the carriage moves, the follower within the elongated member will force its associated rack to move within the carriage, which movement of the associated rack will cause the other rack to have corresponding movement. The angular orientation of the elongated member controls the amount of movement of the other rack and can be adjusted to cause the effective movement of the other rack to be amplified or suppressed.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
163 words
A reciprocating drive mechanism comprising a movable carriage, first and second toothed racks slidably mounted on said carriage at right angles to each other with the teeth thereof intermeshing, drive means for reciprocating said carriage in a direction parallel with said first rack, said first rack being aligned with the path of movement of said carriage and the angle of inclination of the teeth of said first and second racks being such that movement of the second rack imparts a movement to said first rack, an elongated slideway having a track thereon, and a member attached to said second rack and engaged with said track, alignment of said elongated slideway with the inclination of the teeth of said first and second racks reducing the relative travel between said carriage and said first rack and alignment of said elongated slideway opposite to the inclination of the teeth of said first and second rack increasing the relative travel between said carriage and said first rack.
Claim 2
Dependent Claim
163 words
A reciprocating drive mechanism comprising a movable carriage, first and second toothed racks slidably mounted on said carriage at right angles to each other with the teeth thereof intermeshing, drive means for reciprocating said carriage in a direction parallel with said first rack, said first rack being aligned with the path of movement of said carriage and the angle of inclination of the teeth of said first and second racks being such that movement of the second rack imparts a movement to said first rack, an elongated slideway having a track thereon, and a member attached to said second rack and engaged with said track, alignment of said elongated slideway with the inclination of the teeth of said first and second racks reducing the relative travel between said carriage and said first rack and alignment of said elongated slideway opposite to the inclination of the teeth of said first and second rack increasing the relative travel between said carriage and said first rack.
Claim 3
Dependent Claim
159 words
A reciprocating drive mechanism comprising a movable carriage, first and second toothed racks slidably mounted on said carriage at right angles to each other with the teeth thereof intermeshing, said first rack being aligned with the path of movement of said carriage and the angle of inclination of the teeth of said first and second racks being such the movement of the second rack imparts a movement to said first rack, an elongated slidway having a track thereon, and a member attached to said second rack and engaged with said track, alignment of said elongated slideway with the inclination of the teeth of said first and second racks reducing the relative travel between said carriage and said first rack and alignment of said elongated slideway opposite to the inclination of the teeth of said first and second racks increasing the relative travel between said carriage and said first rack, and means for varying the inclination of the elongated member.
Claim 4
Dependent Claim
159 words
A reciprocating drive mechanism comprising a movable carriage, first and second toothed racks slidably mounted on said carriage at right angles to each other with the teeth thereof intermeshing, said first rack being aligned with the path of movement of said carriage and the angle of inclination of the teeth of said first and second racks being such the movement of the second rack imparts a movement to said first rack, an elongated slidway having a track thereon, and a member attached to said second rack and engaged with said track, alignment of said elongated slideway with the inclination of the teeth of said first and second racks reducing the relative travel between said carriage and said first rack and alignment of said elongated slideway opposite to the inclination of the teeth of said first and second racks increasing the relative travel between said carriage and said first rack, and means for varying the inclination of the elongated member.
Claim 5
Dependent Claim
34 words
A mechanism according to claim 1 in which said track is defined by a groove in said elongated slideway and said member attached to said second rack includes a roller movable in said groove.
Claim 6
Dependent Claim
32 words
A mechanism according to claim 1 in which the teeth of said first and second racks are inclined at an angle of at least 45* to the longitudinal axes of said racks.
Claim 7
Dependent Claim
25 words
A mechanism according to claim 1 in which the maximum angle of inclination of said elongated slideway is 45* with respect to the first rack.
Claim 8
Dependent Claim
17 words
A mechanism according to claim 1 wherein said carriage is slidably carried between a pair of shafts.
Claim 9
Dependent Claim
37 words
A mechanism according to claim 1 wherein said carriage includes a horizontal slideway and a vertical slideway, said first rack is slidably received in said horizontal slideway and said second rack is slidably received in vertical slideway.
Claim 10
Dependent Claim
21 words
A mechanism according to claim 1 wherein said member attached to said second rack is mounted half-way along said second rack.
Claim 11
Dependent Claim
29 words
The combination according to claim 1, in which said drive means comprises a rotatably driven cam and a cam follower roller carried by said carriage and engaging said cam.
