may concern:

Be it known that I, GUY A. LYON, a citizen of the United States, residing at Detroit, in the county of ayne and State of Michigan, have invented certain new and useful Improvements in Hood Hinges, of which the following is a specification.

This invention relates to hood hinges, and has for its object a hood hinge in which the hood sections can be given a varying locatiOn with respect to the hinge knuckle. In the ordinary hood top hinge a rough form of the old piano hinge is utilized and the knuckle rises above the upper surface of the wings for substantially the amount of its entire diameter. This is considered rather inartistic in the better models of automobiles. Various concealed hinges have been proposed and some of them used.` These, however, are not very well adapted for use on the ridge of the hood. They are better adapted for use at the sides of the hood where the two portions of the wings are hinged together and break inward instead of outward as at the top.

It is the object of the present invention to provide a hood hinge which permits the knuckle and the knuckle pin -to be more or less sunk below the upper surface of the hood. The degree of sinking the knuckle and knuckle pin with respect to this upper surface can be altered to suit the taste of the designer. This will more fully appear in the description following.

Fig. l is a perspective, fragmentary in character, showing the hinge and the adjoining hood portions.

Fig. 2 is a section on 1.

Fig. 3 is a longitudinal section through the hood hinge.

Fig. 4 is a fragment-ary perspective showing one of the hinge units.

The ordinary rough piano hinge now used in cheap body construction comprises knuckles formed by curling up into small cylinders alternate portions of the meeting edges of the wings. In place of this construction in my improved hinge and hood structure, I employ two separate vhinge Wings or deep channels a and b. These have alternate projecting porti ns a and b. These projecting portions ar formed each into a cylinder having an xtension web extending down in the trough of the channel to aid 1n comthe line 2-2 of Fig.

Va separate hinge of upwardly-opening channel strips having pleting a cylinder by closing it together, and also aid in anchoring the sections'rof the hood, as will presently be described. These extension webs are designated a2 and b2 depending upon whether associated with hinge member a or hinge member b.

The two hood sections are designated c and f. The hood section e is provided with a flange e and the hood section f with a flange Each of these anges is -bent at right angles to the main portion of the wing forming elbows adapted to be slipped into the channels between the outer wall of the channel and the hinge knuckle webs. Now obviously the depth of these flanges or elbow-s may be varied and also the depth to which they are slipped into the channels a and b. This, of course, determines the height of the hood section with respect to the hinge knuckle and consequently determines the degreeV this hinge knuckle is sunk with respect to the top surface of the hood. The two walls of the channel, the hood section flange and the hinge knuckle web may all be fastened together in the desired position, preferably by spot-welding.

What I claim is:

1. In a hood, the combination of two hood sections having their adjacent edges turned down into substantially perpendicular flanges, and a separate hinge section comprising a pair of upwardly opening channel strips having their inside adjacent walls provided with separated and extended portions curledover into knuckle eyes oset inwardly Jfrom the channel to present away from the channel opening, said eyes havingextending webs running down into the channel, the knuckle eyes of the two channels being in staggered'relation and arranged to align end to end, a knuckle pin running through said aligned knuckle eyes, said perpendicular flanges of the hood sections being abutted against the said webs of the knuckle eyes and extended down into the said upwardly opening channels and means for permanently uniting the flange to the web and' the two walls of the channel.

2. In a hood, the combination of two hood sections having their upper adjacent edges turned down into substantially right angular flanges having free lower edges, and section comprising a pair their inside Walls provided Withseparated and extended portions curled into knuckle eyes each offset inwardly from the. channel to present away from the channel opening and extend only part Way over the channel opening of the other hinge section when the parts are assembled together, extending only part Way over the channel of the hinge section of which they are apart vertical web run-v and provided each with a ning down into the channel and lyino against the inside Wall of suchchannel, the said knuckle eyes of the tWo channels besaid eyes In testimony whereof I aixrmy signature.l
