Abstract

556,504. Repeated-impact testing machine. BRENNAN, J. B. June 23, 1942, No 8593. [Class 106 (ii) ] The specimen is driven outwardly by mechanical contact means against the influence of a spring which returns it under control of the driving means until the head of the specimen impacts against the anvil, the construction being such that the contact means re-engages the specimen without shock. The base-plate 1 supports cam casings 8 and a massive anvil-holding casting 9. Behind this is a block 10 sliding on rails 11. A driving shaft 2 having at one end a fly-wheel 3 and at the other a counter 4 is driven from an electric motor. Fig. 3 shows a section of one impact unit of which two are provided in the casings 8 which form oil baths. The cam 14 is bolted to a flange 15 on the shaft 2 and engages a tappet 17 which reciprocates in a bearing 16 and engages the head of a long hardened sleeve 18 which slides in a cast-iron anvil 19 removably fitted to the casting 9. A spring 20 keeps the sleeve 18 and tappet 17 in contact with the cam 14. The specimen has a striking head 21 and a trip-portion 23 having a notch 21a between them. A slot 24 and screw 25 prevent the sleeve from turning, while a slot 26 has passing through it a pin 27 having an insulated head engaging a spring 29. When the specimen breaks, the trip moves past the pin 27 which drops and allows the spring 29 to make an electric contact and stop the motor. In operation, the block 10 is run back, distance pieces 33 and springs 31 removed, and the trips 23 of the specimen inserted into the sleeves 18. The distance pieces 33 and springs 31 are replaced and the block 10 moved back by turning the screwed shaft 12 so as to clamp the distance pieces against the anvils. The motor is then started. The specimen is passed through the opening 34. The springs are compressed by the cam and the parts return under the influence of the springs, the sleeve 18 leaving the head 2 at impact and completing its movement under influence of spring 20.
