Filed: 1959-05-04
Abstract: 870,563. Record changers. COLLARO Ltd. April 7, 1960 [May 4, 1959], No. 15202/59. Class 40 (2). In a record changer of the kind described in Specification 859,372 having a cam-disc performing one revolution for each automatic cycle and in which cam-disc a follower, controlling the horizontal movements of the pickup, enters an outer groove after the last record has been played, the cam-disc is arrested and located in its datum position by a follower thereon which engages a notch in a spring- loaded lever, and the machine is stopped by means associated therewith. Fig. 2 shows the condition of the apparatus during the playing of a record before an automatic cycle has been initiated. When an automatic cycle commences a follower 18 on the cam-disc 7 leaves a V-shaped notch in a spring-loaded lever 20 carrying a pin 22 which meanwhile rests against the end of a slot 23 in the base-plate 1. Near the end of the automatic cycle when the follower 18 reaches the position shown in Fig. 3, the lever 20 moves to the position shown and moves with it a lever 47 which allows a bar 51 to be moved longitudinally under the influence of a spring 52 on to a step 57 on the base-plate 1. If the last record has been played, the follower 17 controlling the pick-up arm is following the outer groove 59 in the cam-disc and comes into contact with a lug 61 on a lever 62 so that the other end thereof kicks the end of the bar 51 from the step 57 and takes up the position shown in Fig. 4. As the follower 18 enters the V-shaped notch in the lever 20 both lever 20 and lever 47 move clockwise and the end 49 of lever 47 urges the bar 51 against the end of a switch lever 35 and trips it to the position shown in Fig. 5 to break the switch contacts 26, 27 and stop the machine.

Abstract: 552,477. Electric-welding. LATIMER, J., CROSS, J. E., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Dec. 3, 1941, No. 15590. [Class 83 (iv)] In a flash welding apparatus having a variable minimum-gap. i.e. distance between the work clamps at the end of the welding operation, a pointer movable proportionately with the movable work platen, co-operates with a scale for indicating the position of the pointer for different valves of the minimum gap and also cooperates with a second scale which is adjustable for indicating the position of the pointer corresponding to the position of the movable work platen at the ends of the flashing and upset periods. The work platens may thus be preset in correct initial position to receive work of different sizes and classes in relation to the desired allowances for flash, upset and minimumgap. An arcuate scale 3, graduated in teams of the minimum gap between the work clamps is secured to a plate 6 in which is mounted an angularly adjustable flashing scale 4 to the spindle 8 of a pointer 5. The scale 4 is carried by a boss 7 and is provided with graduations to indicate the travel of the movable platen, the mark U indicating the end of flashing and beginning of upset period when extra pressure is to be applied to complete the weld and the mark O indicating the end of the welding operation. The scale 4 is provided with a window 15 through which a portion of scale 3 is visible, the scale 3 co-operating with a mark M, G on the scale 4 to set the scale 4 to the required minimum gap. The scale 4 is connected to the scale 3 by a slot and bolt and is secured in position thereon by a clamping nut 18. The spindle 8 of the pointer is connected to one part of a clutch 9 which is pressed by a spring 12 against the other part carrying a spindle 10 connected by linkage 11 to the movable platen 2. The linkage is adjustable to vary the travel to suit different welding machines. The front part of the clutch carries an adjustable abutment 21 to engage the actuating plunger 20a of normally closed switch 20 which is secured to a bracket 19 on the boss 7 of the scale 4 so that the tripping of the switch is variable correspondingly with the movement of the scale 4. When the scales and pointer are set in required position the work parts are fixed in position in the clamps and welding started, light pressure being applied to the movable platen to start the flashing period. When the pointer reaches the mark U the flashing period ends and increased pressure is applied. When the pointer is between marks U and O the abutment 21 engages the plunger 20a to open the welding switch. When the pointer reaches the mark O the upset period ends and the weld is thus completed. The bracket 19 carries a projector 23 which engages the abutment 21 and trips the clutch 9 to arrest the pointer in case of any further movement of the movable platen. The apparatus may be applied to manually or automatically controlled welding machines.
