Abstract
Abstract A press having a frame includes a slide reciprocatingly mounted on the frame for cooperation with the bed to perform work on workpieces. A drive means for reciprocating the slide is connected thereto by adjustable connection means for adjustable movement of the slide toward and away from the bed to vary the shut height. A variable indicating means is mounted on the slide for indicating the adjusted shut height position of the slide. An indicating drive mechanism is mounted on the adjustable connection for driving the indicator to vary the indication thereon and show the adjusted shut height position of the slide when the adjustable connection is adjusted. A flexible drive shaft drivingly connects the indicating drive mechanism with the indicator.

Claim 1
Independent Claim
121 words
In a press having a frame, slide means reciprocatingly mounted on said frame for cooperation with a bed on said frame to perform work on workpieces, drive means for reciprocating said slide means, adjustable connection means connecting said drive means to said slide means for adjustable movement of said slide means toward and away from said bed, variable indicating means mounted on said slide for indicating the adjusted position of said slide, indicating drive means mounted on said adjustable connection means for driving said indicating means to vary the indication thereon and show the adjusted position of said slide means when said adjustable connecting means is adjusted, and flexible shaft means drivingly connecting said indicating drive means with said indicating means.
Claim 2
Dependent Claim
121 words
In a press having a frame, slide means reciprocatingly mounted on said frame for cooperation with a bed on said frame to perform work on workpieces, drive means for reciprocating said slide means, adjustable connection means connecting said drive means to said slide means for adjustable movement of said slide means toward and away from said bed, variable indicating means mounted on said slide for indicating the adjusted position of said slide, indicating drive means mounted on said adjustable connection means for driving said indicating means to vary the indication thereon and show the adjusted position of said slide means when said adjustable connecting means is adjusted, and flexible shaft means drivingly connecting said indicating drive means with said indicating means.
Claim 3
Dependent Claim
56 words
The device of claim 1 wherein said slide means has a front surface, an opening in said front surface of said slide means, said indicating means being mounted in said opening, said indicating means having an indicating face, said indicating face being tilted forwardly from the vertical relative to said front surface of said slide means.
Claim 4
Dependent Claim
36 words
The device of claim 1 wherein said adjustable connection means includes a rotatable adjusting gear, said indicating drive means including a rotatable driven gear drivingly engaged with said adjusting gear and with said flexible shaft means.
Claim 5
Dependent Claim
