SCHEMMEL HOOD CONSTRUCTION Application filed April 29, 1982. Serial, No. 608,282.

The invention relates to hood constructions and it has particular relation to the manner of hinging parts of the hood together and to a vehicle body.

In certain respects the invention relates to that disclosed in my prior applications for patents on hood constructions, Serial No. 588,566 filed January 25, 1932, and Serial- No. 602,516 filed April 1, 1932.

Similarly to the application for patent last filed, one object of the present invention is to provide a hood construction in which the wings of the hood are hinged directly together by coacting rolled edges and hinged to the radiator and the cowl of a vehicle without necessitating the use of a supporting pivot connecting such parts of the vehicle.

Another object of the invention is to provide a hood construction in which the wings of the hood are hinged together and to the radiator and cowl of the vehicle, directly'by rolled edge portions of the wings without requiring the use of any separate pintles, pins or the like.

Another object of the invention is to provide a hinge construction for a pair of plates or the like, in which a rolled edge portion of one of the plates constituting a part of a rolled edge hinge connecting them, may be employed directly as a pintle or pivot portion for pivoting the plates on a stationary support.

Another object of the invention is to provide an improved hinge construction for hoods, of this general character, which is so constructed that the outwardly exposed and finished surfaces of the hood in the region of the hinge will not be marred, scratched or otherwise injured during any opening or closing movement of the hood wings, and which has a smooth and efiicient manner of operation throughout such opening and closing movements.

Another object of the invention is to provide an improved hood wing hinge, which has desirable flexibility to the end that un desirable strains will not be imposed upon the pivotal connection between the wings,

hood and vehicle in closing or opening of either wing thereof, so that the hinge will be extremely durable and resistant 'to strains such .as usually caused during final opening movement of either wing when considerable momentum force is imparted to the hinge connection.

Other objects of the invention will be ap' parent from the following description, the drawing relating thereto and the claims hereinafter set forth.

For a better understanding of the invention reference may be had to the accompanying drawing forming a part of the specification, in which Figure 1 is a fragmentary plan view of a vehicle-having a hood construction designed according to on form of the invention;

Figure 2 is a cross-sectional view on a larger scale, taken substantially along the line 22 of Figure 1,

Figure 4 is a cross-sectional view on a larger scale taken substantially along the line 44 of Figure 2;

Figure 5 is a perspective, end view of the hood, particularly illustrating the hinge connection between-the hood wings, as seen whden the hood is removed from the vehicle; an

Figure 6 is an end view on a larger scale, as seen substantially along the line 6-6 of Figure 5.

Referring to Figure-1, a motor vehicle is the veillustrated at 10, the radiator thereof at 11 wings are pivoted on a long pin or pintle connected at opposite ends to the radiator and cowl, and the present invention particularly is concerned with the manner of hinging the wings together and to the radiator and cowl in an improved manner.

Referring now particularly to Figures 5 and 6, the hood wing 15 is illustrated as having an inwardly turned flange 17 and the wing 14 similarly as having an inturned flange 18, such flanges being shown as spaced and substantially parallel when the wings are in closed position. The flange 17 is rigidly connected as by Welding, for example, to a similar flange 20 on a male hinge element 21 formed by rolling an edge of the element in the manner shown. The flange 18 on the hood wing 14 similarly is connected to the flange 22 of a female hinge element 23 adapted to cooperate with the male member 21. It of course should be understood that the dges of the wings 14 and 15 may be rolled to provide the male and female hinge elements respectively, without manufacturing such elements separately and then welding them to the wings, but ordinarily the first described manner of manufacturing will facilitate the metal rolling operations. The particular construction of the male and female hing elements has been illustrated and described in my copending applications for patent above identified, and accordingly, it does not seem necessary to explain them herein in detail. It may be added that in many instances the male and female elements may constitute an article of manufacture, to be subsequently connected to hood wings by the purchaser.

When the parts are associated as shown in Figure 6, it is apparent that the male and female members are so related that further closing movement of cit-her hood wing is resisted. In opening either wing, as for example the wing 15 as shown in broken lines, the hook portion of the male hinge element, indicated at 24, finally hooks over the end edge of the female element, indicated at 25, to provide a limit or stop to the opening movement. Of course, if the wing 14 is opened, the male and female members will move relatively in the same manner as when opening the wing 15, although in the one case, the male element will move while the female element will remain stationary, while in the other case the male element will remain stationary and the female element will move. The male and female elements are associated by longitudinally telescoping them and it will be appreciated that the construction as shown simulates the ordinary hood hinge wherein a long pintle or pin is employed, without necessitating use of the latter. It is apparent that the male and-female members are continuous from the cowl to the radiator and hence that water or other matter may not leak into the space below the hood through the hinge. The flanges 17 and 20 on the wing 15 and the flanges 18 and 22 on the wing 14, being positively connected together, will pre- 1 vent the ingress of any water or the like into the motor space although, as stated previously, the male and female elements may be integral with the wings so as to completely eliminate any possibilit of seepage of water or the like between the anges on either wing.

For pivoting the wings 011 the radiator and cowl, the male element 21 extends beyond opposite ends of the hood as shown by Fig. 5, and such pro ecting ends, as also illustrated in Figure 4, preferably constitute a portion of the male element, in which the flange 20 and a curved part of the element, are removed substantially to the line 25. While such projecting ends of the male member may not constitute an arcuate element having a single radius of curvature, they may be satisfactorily pivoted in journals 27 mounted on the radiator and cowl. It would, of course, be possible to have the projecting ends of the male element provided with truly cylindrical surfaces so as to smoothly fit in the journals 27 but normally this would not be necessary as satisfactory pivotal action may be obtained without doing this, and it is much easier to use the projecting ends of the male element without altering their curvature, as to make such alterations would introduce other manufacturing steps and increase the expense of manufacture. The journals 27 have flanges 28 and 29 fitting under portions 30 and 31 of the cowl and radiator and such flanges are secured in position by means of bolts 32. Normally, the hood wings 14 and 15 have their side edges resting on such portions 30 and 31 of the radiator and cowl and this arrangement still further stabilizes the position of the ends of the male element in the journals .27. v

In opening the hood wing 15, for example, it is apparent that the male element will move with the wing and hence pivot in the journals 27 and that finally when the wing reaches its open position, the hook portion 24 of the element will engage the end edge 25 of the female element to hold and lock the wing in open position. If the hood wing 14 is opened, the male element will remain substantially stationary and hence any substantial pivotal movement of its projecting ends in the journals 27 will not be necessary. In a construction of this character, attention is directed to the fact that a considerable manual and momentum force may be exerted through a wing when it is thrown into its open position owing to the moment arm through which the force is imparted by the hand moving the side edge of the wing and this force naturally tends to forcefully continue movement of the hood wing past its intended open position. For example, in opening the wing 15, there is a considerable force tending to move the wing past its intended, open position in which the hook 24 on the male element initially engages the end edge 25' on the female element. In the ordinary hood in which a pintle is used, this force has a very undesirable result in that eventually and ordinarily in a short time, parts of the hinge connection between the wings and between the wings and the cowl the radiator become broken. In the present construction, after the wing 15 reaches the intended final open position, the momentum force of the wing will be dissipated through the give and resiliency of the hinge elements and largely through the female element and adjacent .portions of the wing 14. If the wing 14 is opened, this force tending to move it past its final open position, is resiliently dissipated largely through themale element and the adjacent parts of the wing 15. Moreover, this momentum force does not act appreciably, if at all, on the journals 27 and the male element portions therein except to rotate them, but to the contrary is dissipated mainly through the opposite wing and there is very little tendency to impart any force to the journals or the male elements therein to loosen the journal connections on the radiator and cowl. This may be illustrated perhaps a little more clearly by using the arrow A in Figure 6. In opening the wing 15, when the latter tends to move past its supposed limited open position, the momentum force, instead of acting on the journals 27, merely tends to slightly move the female element and parts of the wing 14, downwardly into the motor space in the direction generally indicated by such letter A. Of course, this movement is slight and practically unnoticeable, but nevertheless it is extremely advantageous in that it cushions the force and prevents the imparting of undesirable forces to the journals 27, as well as to the rolled por-, tions of the hinge.

A hood of the type described may be manufactured very inexpensively because it is only necessary to roll the male and female members from edges of elongate and fiat plates and then fasten such elements to the wings,

' orelse roll such edges directly into edge portions of the wings without manufacturing them separately of the latter. The use of .pintles or pins of any character is avoided and it is only necessary to manufacture the wings and then pivot them on the radiator and cowl by means of projecting ends of the male element. The hinged construction thus provided is water tight and, moreover, its appearance is especially pleasing in that it simulates the ordinary type of hinge to which the public has become accustomed. Moreover, as stated in my prior copending appli-.

cations for patent, the hinge is so constructed that surfaces exposed to view on the wings of the hood will not be marred or scratched during any movement of the wings to their open or closed positions.

Although only one form of the invention has been described and illustrated in detail,

it will be apparent to those skilled in the art that various modifications may be made without departing from the scope of the appended claims.
