Figure 3' isaviewsimilar to Figure 1 with the panel rotated into a horizontal position with the back upward. Figure 4 is a view similar to Figure 2 with the panel rotated through approximately 180 from its interior position to expose the entire back of the panel for access at the exterior of the enclosing cabinet.
Figure is a detail'view on the line VV of Figure 3.
The swingout construction of the present invention is starting of direct current motors.
At the opposite-sides of the backfacetof theplate 3 are mounted a pair of angles 4 and 5 extending beyond the plate 3 bottom thereof. On the mounted an angle 6, the upright 'legofwhich has a width substantially the same as the space between the rearwardly directed legs of the the lower ends of the angles 4 and 5 being bolted to'the-angle 6-by studs 7 and the upper end of the angles 4 and 5 being bolted to suitable brackets 8 on the top wall of the cabinet by studs 9.
2,769,940 Patented Nov. 6, 1956 2'. Intermediate the ends of the angles 4'and 5 and on the rearwardly directed legs thereof are mounted pins 11, as
openings-through which the pinsextend to provide a pivotal mounting. The upper ends of the straps 12 and 13 are provided with slots 14 through which project pins 15 carried by brackets 16'rigidly mounted upon'the opposite side walls of the cabinet corners.
The rearwardly extending side plates 17 provide protective barriers.
with the angles 6, the slots 14 permittin'g'this tilting until the pins 15 engage the upper ends' of the-slots. The posithe pins 11 with respect to the distributed weight ofthe panel and the elements mounted thereon so that the combined' mass of the panel is'substantially balanced about the access of rotationgFigure 3 is'a stable position. To provide'the complete access to the back'of the panel it is rotated beyond the position of Figure 3 through from its original position into the position'of Figure 4- back' of: the panel panel by the pins 11 and also by the mounting of straps effort and preventing uncontrolled movements of the parts whichniight result in damage. The invention also provides varying degrees of accessibility in suitable positions, providing for the forward tilted position of Figure 2, the horizontal position of Figure 3 and the completely door, a panel within said enclosure, circuit controlling,
