. 40mins (01.180-69) mobile, and terminate the hood directly at the front edges of the front doors, both for a lengthening effect, and for the elimination of matched l surfaces.

A further object is to provide, adjacent to front doors, automatic vertical adjustments for the hood rear corners.

Further objects of my invention will appear as the description proceeds. V 'The accompanying drawing illustrates my in-r vention. Here, Fig. l is a side elevation of the fore part of an automobile; Fig. 2 is a plan view of a part of the automobile illustrated in Fig. 1, here, with someparts left off Fig. 3 is a section substantially on lines 3-3 of Fig. 1, herewith some parts left off; Fig. 4 is a section substantially onlines 4-4 of Fig. 1, here illustratedin a larger scale; Fig. 5'is a section substantially on 30 lines 55 of Fig. 4; Fig. 6 is a modification of the invention.

Referring to -Figs. 1 to seen that an automobile body generally at H) is provided with a roof ll, Windshields l2, and exl5, andtterminates in a'usual dash board [6.

On the body are mounted a pair of front'doors, having main panels I'I, body' beads I8, curved provided (only one is shown) These are formed by the rear edges of the hood-panels 24. Panels H and 24 are in surface alignment. Inthe prefenders 25 (only one is shown) The fore part ofthe body is formed into a usual cowl structure, having fully spaced side vwalls 26 and'closer spaced side walls 21; On hood 26, an anti-squeak (preferably rubber) hood supporting liner 28 is provided.

The body .cowl structure, supports a hinged hood carrying bridge 30 as by spot welded brackets 3l,-and single hinge pins 32, indicated in Figs.

an exposed ventilator shelf, and in the preferred form, hinge it directly on the body of the auto- 5 inclusive, it will be posed'ventilator shelf l3 carrying a usual venti- 'lator l4. This shelf is formed into a hood ledge walls 20, upper frames 2|, and? windows 22. Directly in front of panels l'l', door gaps 23 are 1 ferred form, panels 24 are formed into front W curved nest 55",the hood will be held in open ledge 15, where it laterally. terminates in walls 1 and 2. As is clear from Figs. 4 and 5, pins 32 are provided with washers 33 and lock nuts 34. Pins 32 operate in vertically elongated openings 35 in door pillar side walls 36.

Bridge 30 serves as an adapter for an alligator .5 hood generally at 40, having a substantially hori- ,zontal upper wall 4! (in surface alignment with shelf I3), depending walls 42 (in surface alignment with walls 20) beads 33, and in-turned horizontal under walls 44. In the bridge 30, elonw gated bolt holes 45 and therein mounted bolts 45 form a longitudinal adjustment and securing means between the bridge and hoodunder walls. assuring a desired direct spacing gap between the hood shelf and door curved walls.

By these single hingc pins the hood'is operable for opening and closing. At the rear of liner 26, pins 32'automatically adjust themselves in the vertically elongated openings, maintaining the hood in the desired longitudinal relation to the body to assure constant direct door gaps 23 and a corresponding hood to ventilator shelf gap 51.

For locking the hood in closed position, a well known structure (not new with the applicant) is schematically indicated in Fig. 1; here, a pilot and catch pin 50, a fulcrumed trigger 5i (catch spring not shown), driving compartment operated release rod 52, and initial hood opening spring 53 compose the main elements. This construction is used on many cars; it is simple and prevents the theft'of the battery (now usually in the engine chamber). This is a single point locking andreleasing, and a simple slam closing" hood lock system. It is desired to depress the hood rear end when in locked position to prevent rattles. As is clear from Figs. 1, 2 and 3, bridge 30 is provided with a roller 54,riding on the surface of a cam-shaped spring 55, secured toydash board 16, as by bolts 56. In the position illustrated, the lateral angle portion of the spring willhold the hood downwardly by the component of about 45 angle. When the hood is manually'lifted and the roller passes the hump 55', the spring will assist in lifting the hood. When the roller reaches the upper position, by the exerted spring pressure on the cam corner (at the base of nest 55").

The above described alligator hood system issimple; it eliminates matched surfaces, it has only two self-aligning fulcrum. pins and one remote controlled'lock; pin.

Figs. 1 to 5 inclusive illustrate a single hinged alligator hood construction in direct spacing from the doors and hood shelf. Directly spaced 55 alligator hood construction is not limited to a single hinged system, when it is desired to use 9. directly spaced hood arranged to be supported by a differential hinge. This is illustrated in Fig. 6. Differential hinges are not new with the applicant, and as is clear from the drawing, here adjustable brackets 50 (only one is shown) are springs 55, by their toggle position, depress the hood rear end. When the hood is in open position, by reaching the opposing toggle position (not shown) the springs will hold the hood in open position.

Alligator hood construction is gaining, and the elimination of matched surfaces reduces the cost of construction and increases the lengthening effect even when exposed door pillars are provided below the hood, (not shown). For certain applications, I may continue the hood depending side walls below the usual bead line (not shown).

What applicant claims as his invention:

1. In an automobile, a body forwardly terminating in a cowl structure, front doors on said body having outer surfaces and front edges, a

windshield on said cowl structure, an exposed ventilator shelf formed at the top of said cowl structure in continuation of said windshield and a ventilator therein, a hood ledge in longitudinal and lateral continuation of said shelf, an alligator hood on said ledge aligned with said shelf and having lateral portions terminating at said door edges in surface alignment with said door surfaces, and hinge means for said hood at substantially the extreme sides of said cowl structure.

2. The invention described in claim 1, wherein spring means depress said hood in closed position and support said hood in open position.

3. In an automobile, a body forwardly terminating in a cowl structure, front doors on said body having outer surfaces and front edges, a windshield on said cowl structure, an exposed shelf formed at the top of said cowl structure in continuation of said windshield, a hood ledge. in

' longitudinal and lateral continuation of said shelf, an alligator hood on said ledge aligned with said shelf and having lateral portions terminating at said door edges in surface alignment with said door surfaces, and hinge means for said hood at substantially the extreme sides of said cowl structure.

4. The invention described in claim 3, wherein spring means depress said hood in. closed position "and support said hood in open position.
