Abstract

866,682. Leather-working machines. MERCIER FRERES. Aug. 7, 1958 [Sept. 26, 1957], No. 25309/58. Class 76. [Also in Group XXIV] In a machine, such as a tannery machine, having moving parts, some of which are protected by a cover while others are exposed, the cover, or a part thereof, is movably mounted and associated with an electric switch controlling the exposed moving parts so that any shock or force exerted on the cover (e.g. by an operator who has lost his balance) causes the stopping of the exposed parts. The tannery machine shown comprises a bladed roller 2 which is belt-driven by a motor 3, a roller 5 which is chain-driven by a motor 13, and one or more conveying rollers 6 on an arm 7 which is oscillated between open and closed positions by an eccentric mechanism 16. The mechanism 16 is driven by the motor 13 through a coupling controlled by a pedal 18. When the arm 7 is in the closed position the conveying rollers 6 lie adjacent to and are driven by a gear fast with the roller 5; alternatively the conveying rollers may be driven by a belt which is tensioned only when the arm 7 is closed. The upper part of the machine is protected by a fixed cover part 19a to which is hinged, e.g. by a flexible plate, a movable cover part 19b associated with a microswitch so that any displacement of the part 19b stops the motor 13 and applies a brake associated therewith. In a modification the whole cover is in one piece and is movably carried by swinging links, Fig. 5 (not shown). In addition to the movable cover or cover part, the machine may be provided with switch-actuating tripbars such as 24, Fig. 7, in front of dangerous spaces, the bar co-operating with a microswitch 25. The pedal 18 also has a pivoted guard 26, or a trip-bar, co-operating with a microswitch. All the microswitches are connected in series with the coil of a contactor circuit-breaker for the motor 13, the circuit, Fig. 10 (not shown), including remote stopping and starting switches, a local starting button and a thermal relay. Specification 741,916 is referred to.
