  • a security lock shown here as a padlock 190, which may be of a well-known key-operated or combination type, is releasably locked to an aperture provided in the outer end of the latching element 182, the padlock 190 being too large to pass through the aperture 186 thus necessitating its removal before the latching element 182 can be disengaged from the door 144 to permit the latter to be opened.
  • the latching element 182 is biased to its latched position through means of a coil tension spring 192 having one end connected to the latching element 182 inwardly of the cap screw 184 and having its other end connected to a bracket 194 which is cantilever-supported from the hinge support bracket 104.
  • the latch structure 180 prevents the door 144 from accidentally falling on the operator when the latching pins 152 and 166 are released.
  • the notch 188 in the latching element 182 is made sufficiently large so as to permit the door 144 to be tilted out far enough to bring the latching pins 152 and 166 out of alignment with the respective apertures 156 and 170 so that the operator may remove both hands from the latching pins so that one hand can be used to operate the latch element 182 while the other is positioned to support the door 144 when it is released.
  • the front and rear latch structures 106 and 108 for releasably retaining the upper access door 98 in its closed position will be located entirely within the engine compartment 50 and will thus be inaccessible from the exterior of the compartment.
  • the lower access door 144 is in its closed position, it is disposed closely adjacent the respective ends of the handles 128 and 142 of the latching rods 110 and 112 so as to prevent the latch structures 106 and 108 from becoming accidentally unlatched.
  • This relationship of the access door 144 to the handles can be best appreciated with reference to FIG. 7. Accordingly, once a padlock is installed in the latching element 182 of the safety latch structure 180, unauthorized opening of the engine compartment is prevented.
  • An operator support structure is made as an integral part of the access door 144 so as to be located for supporting an operator when he is performing periodic servicing of components located within the engine compartment when the access doors 98 and 144 are open.
  • the operator support structure includes a narrow elongate platform 196 which is formed as an integral leg of the access door 144 and is disposed so as to extend horizontally above the base plate 80, when the access door is in its closed position, between a location just rearwardly of the foremost of the hinges 146 and a location just forwardly of the intermediate vertical support plate 88.
  • a plurality of gussets 198 are secured between the platform 196 and the inner wall of the door 144 to thereby provide support for the platform.

  • the normally outer planar surface of the access door will be in engagement with the outer planar surface 64 of the right channel member 60 and the platform 196 and step 200 will extend outwardly from the channel member 60, the step 200 now being disposed at a level below that of the platform 196.
  • a further step 204 is disposed so as to be located vertically below the step 200 when the access door is open.
  • An operator then wishing to service components located within the engine compartment 50 would first step on the step 204 and from there go to the step 200 and then onto the platform 196 if desired.
  • the steps 200 and 204 are located so as to be rearwardly of the rear pair of wheels 24, so as to be easily accessible to an operator, and that the platform 196 extends between the engine compartment 50 and the upper portion of the right wheel 24.
  • the upper and lower access doors 98 and 144 by providing the upper and lower access doors 98 and 144, the movement of the access doors to their respective open positions is in no way hindered by the rear pair of wheels 24.
  • the operation of the right side shield structure 70 is briefly summarized as follows. Assuming that the upper and lower access doors 98 and 144 are in their closed positions as shown in FIGS. 3 and 4, unauthorized access to the engine compartment will be prevented since the padlock 190 will prevent the latching element 182 of the safety latch structure 180 from being disengaged from the lower access door 144 and with this door closed, the latching rods 110 and 112 cannot be manipulated to release the upper access door 198. Further, the lower access door 144 will prevent any accidental movement of the latch rod handle 128 and 140 in a direction for disengaging the respective upper end portions 110 and 112 from their respective receptacles.
  • both portions of the doors 98 and 144 which overlap the baffle plate 90 will cooperate with the baffle plate to define paths for the passage of air and sound waves.
  • the upper access door 98 will first be returned to its closed position and the latching rods 110 and 112 will be rotated to their respective latched positions. Next, the operator will grasp and retract the latching pins 152 and 166 and simultaneously swing the lower access door 144 to its closed position. Once the door is in place the pins are released and the springs 158 and 172 act to latch them. The element 182 will now be located in the aperture 186 and be engaged with the door 144. To secure the compartment 50, the padlock 190 is then installed.
