A great many engine" hood arrangements have heretofore been proposed and" used especially for locomotives where'the hoods are necessarily of very largesize and therefore normally very heavy and unwieldy to be handled or opened for'access to the engine as well as to the associated equipment'. In certain of'these arrangements 2. multimany of side: doorshave-been formed on the hood but the many hinges and the necessary fitting of the doors to the hood frame entails not only complications but expense in initial cost and maintenanceandin addition does not provide complete accessibilltyto the engine.
It is an objector my invention to provide an improved hoodi which is relatively simpleand economical in construction; operation and-main tenance: as Well as beingcompactandrugged" and afiording complete access to-the engine.
A further object is to provide an improved hood which can be readily and conveniently opened with minimum effort on the part of the operator and which'isadapted'tobe sealed in a simple'and direct'manner.
Other objects and advanta'ges will be more apparent to those skilled" in the art from the ML 3 lowing description of the accompanying drawings in whiclr:
Fig.1 is a diagrammatic perspective ofa' locomotive or other suitable vehicle employing my improved-hood;
Fig, 2 is an enlarged fragmentarysid'eelevation of my improved hood generally at the juncture of two hood sections;

Fig. 5 is a section taken on the line 5-4 of Fig. 2; and
Fig. 6 is a section taken-generally on the line Diesel engine and an electric genera-tondriven thereby or; if" desired; the engine may-bemechanically'connectedto the driving wheels; none' of which" are shown as they are well-knowninthe art and do not per se constitutea part of my present invention; The" compartmenthood- 4 is preferably stationary and consists of sheet metal preferablya continuous'stripto form'sides 5 and 6- and a; top' 1, the sides" being welded or otherwise suitably secured at their lower longitudinal edges to'angle'irons 8 and' s which are bolted "or welded to" the b'ed'frame' I. Thishood section extends preferably from the front wall ill of cab 2" forwardly for substantiaIly'ha-lf the length of the total hood length and it is broadly referred to hereizr'as a hood section for the reason that it covers certain accessories although in the same broadsense it could be for any other purpose so long: as it provides a medium into which or'over which the enginehood" couldbebrought into telesc'opicrelation.
The-engine compartment hoodis formed as a longitudinally movable unitary structure having sides I! and F2 and a top" 13. Suitable angle or channel irons F4 ei-it'end up,- across and down the sides and tops; 2; suitable number' of these frame elements being used at spacedpcints along the hood together with similar longitudinal reinforcin'g members 15; Fig-1 2L Theengine hoodsection 3' is of such size" as compared" to the accessories hood that they may be relatively moved"into-telescopic relation with each other; specificallyby moving the engine hood unit bodilybac'kwards into the accessories hood E. Tofacilitate such telescopic movement the engine hood is provided on each side with a pair of wheels l't and I8; Figs. 2 and 4, these wheels being groovedon' their periphery to ride upon suitable tracks 19' and 20 preferably in the form of tubes or pipes supported 'on brackets 2| which are: bolted as at 22' or otherwise suitably secured to the bed frame I-. cated within and extend for the, full length of bothhood-sectionsi and f. I
' 'Therollersas' shownin Fig. Gare individually supported in U -shaped brackets 23, which are welded or otherwise suitably secured to plates and blocks 24 which are preferably fitted in and secured to the vertical reinforcing members I 4 located at the two ends of the hood.
To afford a simple, direct and yet positive means for holding the sheet metal cover to the hood frames, I preferably employ, as part of the frame structure as shown in Figs. 5 and 6, channel members 14 and 25 respectively at the two The tracks are 10'- .II and firmly held therein. Such a clamping action at both ends of the sheet metal pulls the same taut in a longitudinal direction while the hood is pulled taut vertically and across the top by a pair of members 30 forced into the horizontal channels 25 at each lower edge of the hood sides. The members 28 and 30 may be gradually pushed home substantially simultaneously so that the sheet metal can uniformly adjust itselfduring the tightening operation. The hood for the accessories compartment 4 maybe provided with outwardly facing channels similar to channels I and 25, one of such channels being generally indicated at 3|, Fig. 5. A U-shaped member 32 is shown in its sheet metal clamping position.
To insure adequate sealing against rain or other adverse weather conditions and still permit the hood to be readily opened and closed, I provide the hood section 4 with an angle member 33, Fig. 5, extending inwardly from its front edge. Similarly, angle iron 34 is formed on the inner end of the hood section 3 and is spaced from and slightly overlaps the angle iron 33. These angle irons extend completely along the two sides and across the top of their respective hood sections and a rubber tube or other resilient sealing member 35 is secured to one of the angle irons. As a result, when the unitary movable hood section 3 slides to its forward position the sealing member 35 will be engaged by angle iron 34 to effect closure of the engine compartment. The front end of the hood section 3 may overlap or abut against any suitable radiator or shell 36 and may be locked in closed position by any desired means. grips may be placed at any desired points on the movable hood section.
From the foregoing disclosure, it is seen that in Suitable handles or other I order to have complete access to the engine or its generator within compartment 3 from both sides as well as the top it is only necessary for the operator to move the unitary hood section 3 into telescopic relation with stationary hood 4. The .two pairs of rollers I1 and I8 insure free and easy movement of hood 3 with minimum effort on the part of the operator and without any possibility of thehood being in the way of the workmen when they are repairing or inspecting the engine. The telescopic action not only automatically insures complete accessibility but simultaneously removes the entire physical unitaiy hood structure to a point that is wholly out of sight and out of the path of all workmen. It is not necessary to lay the hood on the ground or on some other part of the locomotive'or to have it swing out over a walkway as is necessary with usual swinging doors, all of which constitutes not only a nuisance but a hazard as well. The movable hood is not only simple and rugged by reason of being a self-contained unitary structure completely self supporting by itself but the entire hood is particularly inexpensive as there are no special fittings, hinges or other elements except those that can be purchased as standard structural members. The sheet metal sides and tops after being stretched into position by the clamps 28, etc., may then be suitably held by screws or rivets at various points such as 29. Gusset plates are provided if necessary to reinforce the angle irons of the hood frame which extend transversely and longitudinally.
It will of course be understood that various changes in details of construction and arrangement of parts may be made by those skilled in the art without departing from the. spirit of the invention as set forth in the appendedclaims.
I claim: 7 l. The combination in a locomotive of the type having a frame provided with a substantially horizontal floor surface extending generally .across and longitudinally of the locomotive and an engine compartment ext nding upwardly from said floor surface, comprising aplurality of different size telescopic hood sections of substantially equal length and adapted when ex,- tended to cover said engine compartment, each of said sections having a straight roof and straight sides which extend from the roof down to substantially the floor surface of the frame thereby to [provide a complete top and side engine enclosure of the same depth as said sides, said roof and sides being formed as a self-contained unitary structure in which the roof and sides extend parallel to the lengthwise axis of the locomotive frame, and means whereby said hood sections are relatively longitudinally movable into telescopic relation so as to render the engine compartment accessible.
2. The combination in a locomotive of the type having a frame provided with a substantially horizontal floor surface extending generally across and longitudinally of the locomotive and an engine compartment extending upwardly from said floor surfaces, comprising a plurality of different size telescopic hood sections one of which is normally stationary and the other of which is bodily movable as a unitary structure complete with sides and top each of which is straight throughout its length extending parallel to the lengthwise axis of the locomotive frame and said sides extending from the top down to substantially said floor surface, the engine compartment being covered from its top down to substantially said flo'or surface when said hood sections are extended, and means whereby said movable section may be bodily moved into telescopic relation with the stationary section to render the engine compartment completely accessible from the top and sides down to substantially said floor surface.
