Abstract
637,007. Hand actuating devices for switches; locking switches. WILLIAMS, H. M. April 20, 1948, No. 10832. [Class 38 (v)] A link 4 connecting together switch handles 3, 3a is formed with a slot 7 and a handle-receiving bore 6 in which the handle 3 is secured by a bolt 5, the slot permitting the handle 3a to be moved in one direction by the link but not in the other, provision being made at holes 9 in the slot for a bolt 8 to effect the control of the handle 3a so that both handles can be moved in unison if desired. The slot 7 may be extended in the link and a hole 9a provided therein so that the handles 3, 3a may be locked facing opposite directions. In another embodiment, Fig. 9, the handles are rectangular in crosssection, and are drilled to receive a split-pin 5a or the movable bolt 8. To prevent the handle 3 leaving the slot the link is drilled at 9c, 9d and one of the bolts' 8 passed through these holes and the hole 9b in the handle. The slot may be also extended and an additional hole 14 provided so that the handles may be locked with one switch " on," the other " off." A further modification, Fig. 12, comprises two bars 4 bent to suit the switch handles and spaced apart by spacers. To prevent the link parting from the handles the bars 4 may be provided with chamfered sides 7a at the slots 7 or the handles may be drilled to receive a crossbar, Fig. 11 (not shown) or a bolt 8, or the bars may be shaped to embrace the knob 3c on the handle, Figs. 13, 14, 15 (not shown). The bars may be provided with a support, Fig. 13 (not shown) which holds the link clear of the switch face-plate. The bars 4 may have holes 22 which can be aligned with a staple 21 secured to the face-plate so that the switches can be locked. Springs 18 may be secured to the link to cause it to return the switches to the initial position when the operator's finger is removed. A solid link slotted to suit the number of switch handles controlled thereby may be used also (Figs. 16, 17, not shown).
