Title: Device for stopping a moving body at a predetermined positionon its track
Inventor: RENE MAGLOIRE
IPC: B25H7/00
Filed: 1961-11-14
Abstract: 985,224. Track apparatus. ETABLISSEMENTS EHL-LATIC. Nov. 14, 1961 [Nov. 19, 1960], No. 40677/61. Heading B7N. In an arrangement for stopping a movable body M, running on tracks 2, at a point which is a predetermined distance from the commencement of the track, the distance is measured by a calibrated rule 1 which is positioned alongside the track and includes marker means which cooperate with photo-electric means on the vehicle to bring it to a halt. The rule is mounted on rollers 3 and includes a portion supplied with a number of equally spaced markers m extending from a zero position on the rule in the direction of movement of the body and a portion 7 calibrated in fractions of the distance between two adjacent markers which extends in the opposite direction. Each marker comprises a rod 8 which can be moved from an inoperative position to an operative position in which it extends upwards from the upper surface of the rule. The predetermined distance is set by moving the required whole number marker to its operative position and by moving the rule in the direction of vehicle motion the required fractional amount, by means of a pinion which engages a rack on the rule and is turned by a hand wheel 6. The body includes a propelling motor which can be driven at fast and slow speeds and three photo-electric arrangements comprising respectively light sources 16a, 17a, 16b and photo-electric cells 16, 17, 16 each of which is positioned so that light passing from the source to the cell can be obscured by a marker rod 8 at its operative position. The body is driven from the commencement of the track at fast speed until cell 16 is obscured by the preset marker, and generates a signal which switches the propelling motor to slow speed; when cell 17 is obscured it generates a signal which switches off the drive and applies a brake.
