[Class 83 (iii).] The file 5 is mounted between upper and lower plungers 9, 18 respectively. The plunger 18 is guided in the base 1 and is reciprocated by an eccentric 4 belt driven. The plunger 9 is guided in a hollow cylinder 8 carried by an arm 6 detachably secured to the base 1. To maintain the tool under tension, a spring 10, Fig. 3, is arranged between the lower end of the cylinder 8 and a collar 11 loosely mounted on the plunger 9 and abutting against a pin 91 thereon. To relieve the tension on the tool when removing it, a hollow cylindrical implement 101, Fig. 2, is inserted in the upper end of the cylinder 8 to depress the collar 11 away from the pin 9<1> ; a pin 11<1> is passed through holes 81 in the cylinder 8 and holes 102 in the implement to hold the spring compressed. The tool 5 is secured in the lower end of the plunger 9 by means of a springy metal member 13 bent over to form two semi-circular jaws between which the end of the tool is clamped. The member 13 is lodged in a recess 14 in the end of the plunger 9 and clamped by a screw 15; the tool is similarly secured at its lower end to the plunger 18. Alternatively, the lower end of the plunger 9 has a longitudinal slot 28, Fig. 5, in which the tool is clamped by a screw 29 ; for fine tools a clamping plate 30 is placed between the screw 29 and tool 5, the plate being positioned by a roll 31 received in a hole 32 in the plunger. Where the tool used has a cross-pin this is received in a downwardly directed slot 34 in the plunger. The arm 6 may be removed and the plunger 9 guided in the lower end of a tubular member 22 held against a ceiling piece 26, Fig. 4, by three stays 24. The collar 11 is provided with lugs 27 projecting through vertical slots in the member 22 whereby the collar can be depressed to compress the spring.

Filed: 1935-09-07
Abstract: 467,331. Skips. DEMAG AKT.-GES. Sept. 7, 1935, No. 13133/37. Divided out of and addition to 467,260 under which a Specification was laid open to inspection under Sect. 91 of the Acts, March 9, 1936. [Class 78 (iv)] The invention described in the parent Specification is modified in that the energy. converter and the auxiliary device are controlled by auto. matically operated valves In the embodiment shown the energy-converter 29 is operated by relative move. ment between the skip and a suspended cable 26, and the anti-breakage flap 30 is con. nected to a piston 32 which is actuated by fluid-pressure from the converter 29 under the control of valves 35, 36, 37. When the skip is at the bottom of the shaft, the piston 29b is raised to its uppermost position by the spring 28 whereby the pressure in the pipe 34a is reduced. If the skip is now loaded, the pressure in the pipe 34b is increased due to the weight of the charge on the flap 30, and the valve 37 is opened, thus permitting the flap to move slowly downwards. When the skip has been raised to a discharge position and emptied, on closing the door 38 the valve 35 is re-opened to allow the piston 29b to descend under the weight of the cable 26 and build up an increased pressure in the pipe 34a. This causes the valve 36 to open whereby pressure is transmitted to the pipe 34b to return the flap 30 to its operative position.
