A tank manhole has a periphery defined by a tubular reinforcing ring 1 which extends through and is welded to the shell 2 of the tank and the manhole is closed by an in and out swing door 3 which seals against the end edge of the ring within the tank in the closed position and which is carried by a universal joint on a substantially straight arm 9 one end of which is hinged to the inner peripheral surface of the ring and the edge of the door adjacent to the hinge is arranged to move away from the ring initially when the door is opened. The arm 9 is hinged at 10 to the inside of the reinforcing ring 1 and a sleeve 11 is slidably mounted on the arm 9 and carries, beyond the end of the arm, a transverse stud 6 which is rigidly screwed into a boss 7 welded to the centre of the door 3. The stud 6 is rotatable in the end portion of the sleeve 11 and the sleeve 11 is also rotatable on the arm 9 and the combination results in a universal joint. A strongback 5 is rotatable on the stud 6 and when a wing nut 8 is screwed inwards along the stud it forces the strongback against the inner peripheral surface of the reinforcing ring 1 when the strongback: spans the inner axis of the elliptical manhole. To ensure alignment between the door and the manhole before the strongback is tightened the stud 6 has a recess into which a projection 16 from the end of the arm enters when the alignment is right. The door is opened, after the strongback has been loosened in six stages, as follows:- (i) The sleeve 11 and, door 3 are slid axially along the arm 9 to the .position shown in chain-dotted line 3a, Fig. II, to enable the part of the rim 4 nearest the hinge 10 to clear the inner edge of the reinforcing ring 1. (ii) The door is swung inwards about its hinge to the position 3b. (iii) The door is turned through 90 degrees about the stud 6 to the position shown in full lines in Fig. III, in which its major axis is vertical. (iv) The sleeve 11 and door 3 are turned about the arm 9 through 90 degrees until the door is in the horizontal position 3c, Fig. III. (v) The door is swung about the hinge 10 out through the manhole to the position 3d. (vi) The door is turned through 90 degrees about the arm 9 into the vertical plane, Fig. V. Fig. V also shows a modification in which an insulating wall 17 is spaced from the shell 2 of the tank and a shroud 18 extends through the wall 17, outwardly flared at the same angle as the reinforcing ring 1 and flush with it. A cork lining 19 is also shown. The chief parts of the device are preferably made of stainless steel.

In the piano action shown, the key 24 is connected to a downwardly extending striker 58 pivoted at its lower end to the whip 52. Connection to the striker is made by a rubber or felt grommet 66 held between knurling 64 and the head of a screw 62 extending from the head of the striker. Driven into the head of the key is a member 70 which carries at its outer end a key-hole shaped slot (Fig. 4, not shown) which engages around the grommet but allows it to be detached if desired. To remove the action, the grommets are withdrawn from the key holes and the strikers moved to the dotted positions where they engage back checks 76 attached to the whips.
