The frame described above has Y60 ‘therefrom, and a front-end closure-34 which con stitutes a ‘rounded continuation of the sides = and roof. The center panel -3l has down-turned ?anges Welded to angle bars 35 and 36 extending 2,407,506 3 4 longitudinally of the housing between the arch members l9 and 29. The flanges ofthe panel 3! lower edges hinged to the upper rails I’! and 18 by hinges 62 similar to the hinges 48. The upper edges of the panels are secured to the angle bars 35 and 36 by bolts 63.

The panel 3i also has a plural ity of ventilating ports 3'! spaced therealong each of ‘which is provided with a cover 38 hav the panels may be swung outwardly, leaving the greater portion of the roof open to admit light to the interior of the housing or provide access thereto from above.

Each of the doors 23 and 29 has a pair of guide and bearing edges of the vanes remote from their pivot pins have lugs '53 pivoted to a control bar M. The side members of the frame'éiii are notched at 15 to permit suf?cient movement of the bar 14 to turn the shutter vanes to closed position as shown in chain lines in'Figure 6. The exterior appearance of the vanes when in closed position is as shown inFigure 3. blocks 5t‘ welded inside the lower ?ange thereof, When the vanes are in open position as shown in Figure 6, the flanged edges thereof present the appearance of grille bars. By this construction, I eliminate the usual grille for protecting the radiator installed behind and a pair of guide blocks 5'17 welded inside the upper ?ange. The blocks 55 and 51 have slots adapted to receive the vertical ?anges of the angle bars 22 and ‘24. Each block‘55 also has a bear 45 the shutter vanes since the latter are made of ing ball 58 positioned in a hole 5g drilled through ' ' metal of sufiiciently heavy gauge to make them the block and the lower ?ange of ‘the door. A strong enough to serve effectively as a protective spring 69 is disposed behind the ball 58 and a grille.’ Any suitable mechanism may be provided plug 6! is threaded into the hole to hold the for operating the bar 14 from the cab to adjust spring and ball in place.

In addition, the com From the above description, it will be appar ent that the sides of the housing ‘H3 are uncle; structed between the panels l3a and Ma and the rear posts l5 and l 6. As a result, when the doors 2‘! and 32) are open, the doors 28' and 2S, respec tively, may be slid along the rails to the positions bination of hinged and sliding doors forming sub occupied by the doors 2'! and '38 when closed. stantially the entire sides of the housing and the Alternatively, both the doors 28 and 29 may be 65 hinged roof panels provides easy access to any‘ slid forwardly or rearwardly. It‘will be evident part of the engine or power plant requiring at that this arrangement provides ready access to tention. The entire construction, nevertheless, any point of the engine or power plant‘ within is relatively simple, being composed almost en~ the housing. At the same time, the location of tirely of plate and standard structural members the hinged doors 2'! and 30 at the extreme front so that it can be readily fabricated at relatively and rear of the sides, leaves them in out-of-the 70 low cost.
