Abstract: 894,886. Sawing. ETABLISSEMENTS GUILLIET. June 21, 1960 [June 22, 1959], No. 21780/60. Class 145. A device for controlling the transverse feed of the log carrier of a saw comprises an arm 55 which is rotatable proportionately to the movement of the carrier and carries vertically-spaced switches C1-C10, vertically-spaced stops 53 on a fixed part 20 and corresponding pushbuttons, one of which when pressed, prepares a circuit which is completed when a corresponding switch C1-C10 is closed by the appropriate stop 53, so that the feed motor is stopped. A chain and worm drive 34, 33 from a shaft driven by the feed motor rotates a shaft 25 to which the arm 55 is clutched by a pivoted member 64 fitting within the groove of a pulley 58. Lost motion is provided in the drive by a pair of pins 28, 29 loosely engaging a pin 27 so that the carrier can be retracted slightly by momentary reversal of the feed motor on the return stroke of the carrier, without altering the position of the shaft 25. The stops 53 are carried by saddles 46 slidable on the annulus 20 and locked to it by handles 48. A pointer 49 and scale 51 indicate the set positions of the stops and a pointer 42 and scale 41 on a bell-shaped member 38 on the shaft 25 indicate the position of the arm 55. In operation, the desired pushbutton is depressed and also a start button for the feed motor. The clutch member 64 is frictionally engaged with the pulley 58 and rotates the arm 55 in the direction to move the switches C1-C10 in turn past the stops 53. When the switch that has been rendered live by the pushbutton is reached, a motor relay is de-energized to stop the feed and a solenoid 69 is momentarily energized to tilt a lever 65 and allow the member 64 to release from the pulley so that a spring 62 returns the arm 55 to its original position against a stop 61.
