4 Claims.

This invention relates to hood constructions and particularly relates to the arrangement of the hood wings and the manner of hinging them together on an automobile body.

An object of the invention is to provide an improved hinge construction with the hinged portions concealed from view and the hood Wings so arranged that only a single line opening, extending centrally longitudinally of the hood, is

19 visible.

Another object of the invention is to provide an improved hood construction in which the hinged hood wing members extend toward each other so that only a single line opening, extending centrally longitudinaly of the hood, is visible, and in which the wing members may be raised and lowered simultaneously without interfering with each other.

Another object of the invention is to provide an 2 improved-hood construction in which the wing members are hinged directly to each other and only a single line opening is visible extending longitudinally centrally of the hood.

Another object of the invention is to provide a hood construction in which the hood wings extend toward each other and are hinged to upstanding sides of a channel member, wherein the relationship between the wings and channel members is such that a maximum of movement of the wings is permitted without causing the finished surfaces of the wings to become marred.

Another object of the invention is to provide a hood construction in which the relation between the wings and hinges is such that the wings may extend toward each other closely adjacent to each other and may be simultaneously raised and lowered without interfering with each other.

Another object of the invention is to provide a hood construction relatively inexpensive to manufacture, simple in construction, and efiicient and effective in use.

Other objects of theinvention will become apparent from the following specification, the drawing relating thereto, and from the claims hereinafter set forth.

Fig. 7 is a cross-sectional view showing another .10 form of the invention, and

Fig. 8 is a cross-sectional view showing another form of the invention. i

Referring in further detail to Figure '1 of the drawing, hood wings ill and 12 are provided .15 which extend longitudinally and are so arranged that only a single line opening, extending centrally longitudinally of the hood, is visible. The radiator and the cowl of the automobile are indicated at M and I6, respectively, and in the em- 2 bodiments shown in Figures 2 to 4, the hood wings are connected thereto through a hinge support I8, which is terminally. secured tothe radiator and cowl. The support l8 comprises an elon gated channel-shaped member, opening upwardly and having a straight bottom portion'and upstanding sides. The sides comprise upstanding straight portions 20 having inwardly bent reversely curved portions 22 extending longitudinally of the support. Each upper edge of the sides is reversely beaded in a spiral manner inwardly and toward the adjacent side to form a male member 24 of a nested hinge, which is more specifically described in the patent to Hall Nos 1,987,774, for Hood construction, the present in- 35 vention constituting an improvement over the construction of the patent referred'to.

The female member 26 of the nested hinge may be formed separately and apart from the male member 24 and comprises a straight portion .40 28 and an inwardly reversely curved portion 30 complementaryin shape to the straight portion 20 and curved portion 22 of the support and terminating in a-curved portion 32. The inner face. of the curved portion 32 is substantially 45 and concentrically spiral with the outer face of the male member 24 when the straight portion 28 is in a position abutting the straight portion 20. The female member 26 is provided at its spiraled edge with a curved, portion 34 adapted to fit 50 around the inner edge of the male member to serve as a stop to hinging movement.

The hood wings l0 and I2 are preferably made of sheet metal material and comprise straight upstanding portions 36, secured in a suitable .55

manner, such as by welding, to the female members 26 on the outer faces of the straight portions 28 longitudinally thereof. Those portions of the hood wings which extend upwardly beyond the top of the curved portions 32 of the female members 26 are suitably bent inwardly and over the adjacent nested hinge to form inwardly directed flange portions 38. ,The hood wings l0 and I2 are then reversely' bent upon the flanges 38 providing the edges 39 and the visible piorjtilons of the hood construction, as indicate a The hood wings extend toward eaclrother with their edges 39 coming closelyadjacent to each other longitudinally centrally ..of .tthe .hood, so as to conceal the hinge structure, and the eupport and leave visible only a single line opening extending longitudinally centrally of the hood. As the centers of rotation of the edges 39 of thehood wings lie in a plane substantially below the plane of the edges 39, the edges 39 are separated from each other to an extent that the wings may be simultaneously raised and lowered without interfering with each other along their pathslof movement, as indicated by the arcs of Figure 2. As indicated by the dotted lines in Figure 2, the movement of the hood when in a raised position is limited by the under side of. the edge 39 striking against the upstanding straight portions 26 of the support 18 adjacent a lower corner. As the outside of the main portions 40 of the hood wings and the edges 39 need be the only portions given a finished appearance,;it can be seen that these portions are not contacted by other portions in raising and lowering the hood wings and the finished surfaces will therefore not be marred.

It is pointed out that the channel support I8 is so mounted with respect to theradiator and cowl, that water draining from the hood is collected within the channel and removed tothe end of the hood, and from there permittedxto fall harmlessly and free of the motor.

It will be apparent from the above description that the male and female parts of the. hinge are so designed that when assembled together by sliding the male section into' the female section, a smooth working shake-proof hinge results, which cannot be disengaged except in precisely the same manner as that in which the parts are assembled. 1

In order to prevent longitudinal movement of the male and female members relative to each other, as shown in Figures'3 and 4, a portion of the male member 24 is removed and the female member 32 is inwardly distorted from its concentrically spiral shape over a portion thereof coextensive with the removed portion of the male member in a manner providing a longitudinal, abutting relationship between the edge 4! of the remaining portion 24 ofthe male' member and theopposing edge '42 of the distorted portion '44 of the female member. I 1

In the modified form of structure shown in Figure 5,.'a construction is :provided in which the hood wings are directly hingedly connected to each other and the channel-shaped support l8 of Figure 2 is dispensed with. In this modification, the hinged Wing l0 and the female hinge member 26 attached thereto are similar in construction to those parts as shown in Figure 2. The hood wing i2 is bent downwardly at the edge 59 to have a downwardly directed portion 52, is then bent outwardly as at 52 and upwardly as at 54, to provide an upwardly opening elongated channel-shaped member. The male hinge member 24 cooperates with the female hinge member 32 in the manner described in regard to the embodiment shown in Figures 2 to 4, andhas a downwardly directed straight portion 56 which is suitably secured, as by welding, along its inner face to the outer face of the upstanding portions 54. In this modification, the pivot axis of the hinge is ofiset to one side of the longitudinal' center of thehood construction, which is substantially at the line between the edge 39 and ...,Do rtion 59; and also it can be seen that the edge '39 and portion 59 may be closer to each other than'the edges 39 in the embodiment shown in Figure 2, as the hood wing I2 is pivoted about the same axis asthe hood wing 10 and the arcs described by the edges 39 when the hood wings are simultaneously raised would be concentric and-the two edges moving in opposite directions,

so that the hood wings could be simultaneously raised and lowered without the edges 39 interfering; with each other. The ends of the hinge may bepivotally mounted on the radiator and cowl ina manner similar to that more specifically described in the patent to Hall No. 2,006,163.

-The channel-shaped support IS in Figure 2 may be modified as disclosed in Figure 6, where the upwardly directed sides are terminated at the top of the straight portions 29, the male member 24 being formed of a separate sheet metal member having a straight vertical portion 58 secured along its inner face to the outer face of the straight portion 29, as by welding. Other suitable securing means, such as riveting or the like, may be substituted for the welding suggested in connection with this structure.

A modified structure is shown in Figure '7, in which the sides of the channel support l8 are inclined inwardly, so as to permit the hood wingsto move to a greater distance when they are raised before the under side of the edges 39 is stopped by striking against the inner faces of the straight portions 20. It is to be understood that the hinge may be constructed, if desired, so that the inner edge of the female portion of the hinge is stopped by the male member before the edge strikesv against the inner face.

It is desirable to have the hood wings extend toward each other, with. their edges as close to each other as is possible without interference with each other when the hood wings are raised or lowered simultaneously, and in Fig. 8 a structure is provided in which the portions 69 of the hood wings adjacent the edges 39 are offset downwardly so that the edges 39 lie in substantially the same plane as the plane through the pivot axes of the opposed hood members. It is evident from this construction that when the hood wings are raised or lowered simultaneously the arcs described by the edges 39 would not intersect, but that the edges 39 would immediately begin to recede from each other as the hood members are raised simultaneously and inter- .ference between the two hood wings is prevented invention, the scope of which is commensurate with the appended claims. I
