Inthe example shown, provision of a concealed elongating hinge for the butt Iii is secured to the frame B and the butt hanging closures, such as automobile doors, the i! is fixed to the closure C.

In other words, the sections of the shank end portions 21 included between the edges I8l9 and --2l, as formed by the intersections of the planes P, are of constant dimensions substantially equalling that of the distance between said edges, due to the fact that the variable angular position of the shank end portions relative to the openings l6-l'! during movement of the shank end portions in curvilinear paths as governed by the pintles 38-31 is compensated by the variable cross-sectional width of said shank end portions disposed in said openings during various stages of movement of the shank end portions along said curvilinear paths, except that those sections, such as that formed by the intersection of the plane P, between the edges 20-2l, during stages of movement of the lever at one end portion of its curvilinear path, have dimensions less than that of the distance between said edges 20-21, whereby the butt H may independently swing about its pintle 3| for a predetermined distance at the beginning of its opening movement and at the end of its closing movement.

In swinging the closure C to an open position, the butt II will first swing from the position shown in Figure 2 to that illustrated in Figure 4 without affecting the relative positioning of the remaining parts of the hinge, and without any offset or elongating action, whereby the closure C may clear the closure frame B. Then, as shown in Figure 4, the edges 2lJ-2l of the butt H slidably contact the faces 28-29 of the lever shank in a manner whereby further opening movement of the hinge will bring about the desired elongating or throw-out action between the pivoted link end portions and the sliding shank end portions connecting the butts. On the return swing of the closure C, the edge 2! slidably forces the levers 24-25 into their normal closed positions, at which time the edge 2| is disposed adjacent the entrance of the notch 32, thus allowing the butt II to complete its final closing movement, without affecting the remaining parts of the hinge, this final movement being the same as the action of a single pintle hinge, whereby the closure may swing into its frame without requiring more than the usual angle or bevel therein.

Various changes may be made in the form of the invention herein shown and described, without departing from the spirit of the invention, or the scope of the following claims.

I claim:

1. A hinge construction comprising a pair of butts having openings transversely therethrough, said openings being defined at opposite sides of said butts by edges, a plurality of levers each including a link end portion and a shank end portion, means pivotally connecting said levers in crossed relation intermediate their end portions, means pivotally connecting said levers at their link end portions each to one of said butts, said shank end portions including convergent faces contacting said edges at opposite sides of said butts, said shank end portions being movable in curvilinear paths as governed by said pivot means to vary the angular and axial relationship of said shank end portions to said openings, the sections included between said edges during various stages of movement of said shank end portions relative to said openings having a constant dimension substantially equalling that of the distance between said edges.

2. A hinge construction comprising a pair of butts having openings transversely therethrough, said openings being defined at opposite sides of said butts by edges, a plurality of levers each including a link end portion and a shank end portion, means pivotally connecting said levers in crossed relation intermediate their end portions, means pivotally connecting said levers at their link end portions each to one of said butts, said shank end portions including convergent faces contacting said edges at opposite sides of said butts, said shank end portions being movable in curvilinear paths as governed by said pivot means to vary the angular and axial relationship of said shank end portions to said openings, the sections included between said edges during various stages of movement of said shank end portions relative to said openings having a constant dimension substantially equalling that of the distance between said edges, a given one of said shank end portions being provided with a reduced portion receiving one of said edges, whereby those sections included between the edges contiguous to the given shank end portion during stages of movement at one end of the curvilinear path of the given shank end portion have dimensions less than that of the distance between said edges.

3. A hinge construction comprising a pair of butts including cam walls defining openings extending transversely through said butts, a given one of said butts including a cam wall formed with a tooth, a plurality of levers each including a link end portion and a shank end portion, means pivotally connecting said levers in crossed relation intermediate their end portions, means pivotally connecting said levers at their link end portions each to one of said butts, said shank end portions including convergent faces each slidably contacting the cam walls of one of said openings whereby said shank end portions, upon relative swinging movement of said butts, are moved along curvilinear paths transversely of said butts, one of said shank end portions being provided in one of its convergent faces with a notch for the accommodation of said tooth, said notch being defined by an arcuate wall conforming to the arcuate movement of said tooth about the pivotal axis of said given butt.
