Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
137 words
In a press mechanism having means for adjusting the shut height, a device for indicating the instantaneous position of a movable slide relative to a fixed frame comprising: (a) a first rack slidably supported in the slide and adapted to engage the frame and remain stationary relative thereto when biased in one direction outward from the slide; (b) means alternatively for yieldably biasing said first rack in the one direction and for moving the first rack in the other direction for withdrawal into the slide and away from contact with the frame; (c) a pinion carried by the slide and in mesh with the first rack; and (d) an indicator on the slide driven by the pinion and operative to display the position of the slide relative to the frame when the first rack engages the frame.
Claim 2
Dependent Claim
137 words
In a press mechanism having means for adjusting the shut height, a device for indicating the instantaneous position of a movable slide relative to a fixed frame comprising: (a) a first rack slidably supported in the slide and adapted to engage the frame and remain stationary relative thereto when biased in one direction outward from the slide; (b) means alternatively for yieldably biasing said first rack in the one direction and for moving the first rack in the other direction for withdrawal into the slide and away from contact with the frame; (c) a pinion carried by the slide and in mesh with the first rack; and (d) an indicator on the slide driven by the pinion and operative to display the position of the slide relative to the frame when the first rack engages the frame.
Claim 3
Dependent Claim
96 words
The device of claim 1, wherein: (a) a rack carrier is attached to the slide and defines a guideway along which the first rack moves in a direction parallel to the direction of movement of the slide relative to the frame; (b) an abutment extends from the frame to a position in alignment with the rack carrier; and (c) the first rack is moved in said one direction along the rack carrier to extend therefrom to yieldably engage said abutment and in the other of said directions to a position out of contact with said abutment.
Claim 4
Dependent Claim
49 words
The device of claim 2, wherein: (a) the means for biasing is a piston and cylinder motor connected to a second rack for reciprocation thereof; and (b) the second rack is mechanically connected to rotate the pinion and to drive the first rack in one and the other directions.
Claim 5
Dependent Claim
22 words
The device of claim 3, wherein the pinion and second rack and the piston and cylinder motor are supported on the slide.
Claim 6
Dependent Claim
84 words
The device of claim 2, wherein: (a) a first face is formed on the rack carrier inclined at an acute angle to the direction of movement of the first rack in the rack carrier; (b) a second face complementary to the first face is formed on the slide and abuts the first face; and (c) said rack carrier fixed to the slide in a selected position wherein interaction of said first and second faces positions the pinion in backlash-free engagement with the first rack.
