Abstract
In the disclosed apparatus, a slide is mounted on a guide bar for longitudinal as well as rotary motion. A recording instrument projects from the slide and a spring biases the slide about the guide bar so as to press the recording instrument against the record carrier. The speed measuring device moves the slide longitudinally on the basis of the measured speed.
Claims7
For recording the output of a speed measuring apparatus on a record carrier moving in a given direction, a recording device comprising:
- a guide bar, a slide, recording means, gear means coupling the speed measuring device to the slide and exhibiting slack therein, said slide being mounted on said guide bar for sliding movement along the bar as well as rotary movement, said recording means being mounted on said slide, said slide being linearly movable transverse to the moving direction of the record carrier and carrying said recording means so that the recording means can be held against the record carrier, spring means being coupled to the slide and angularly oriented simultaneously to bias the slide rotationally about the guide bar against the record carrier and longitudinally along the guide bar to bias the slide sufficiently to eliminate the slack in the gear means.
For recording the output of a speed measuring apparatus on a record carrier moving in a given direction, a recording device comprising:
- a guide bar, a slide, recording means, and spring means for applying a resilient force, said slide being linearly movable transverse to the moving direction of the record carrier and coupled to the speed measuring device and carrying said recording means while holding the recording means against the record carrier, said slide being mounted on said guide bar for sliding movement as well as rotary movement, said recording means being rigidly connected to said slide while said spring means is coupled to said slide and biases said slide rotationally bout said guide bar and said recording means against the carrier, said spring means including a leaf spring, the end of the spring being fastened to said slide while the other end forms a guide shoe resting on a plane parallel to the plane of the record carrier.
