SPECIFICATION forming part of Letters Patent No. 251,591, dated December 27, 1881.V

Application filed September 3, 1881. (No model.) l

To all whom it may concern VBe it known that l, GUSTAV L. JAEGER, a

citizen of the United Sta-tes, residing at New York, in the county and State of New York,

have invented new and useful lmprovementsin Spring-Hinges, of which the following is a specification.

This invention relates to that class of springhinges which consist of two leaves and a torsional spring composed of a hat strip ot' metal adapted to be twisted by turning one of the leaves, whereby the torsional action ot` the metal plate will act to return the leaf to its normal position.

The objects of my invention are to simplify the construction of this class of hinges and to reduce the cost ot' manufacturing the same, whereby an efticientbut comparatively inexpensive hinge can be furnished, which is especially adapted for the lids of boxes. This object l accomplish by the construction of parts illustrated in the accompanying drawings, in which- Figure 1 represents aperspective view of my hinge when made of sheet metal. Fig. 2 is a transverse section of the same in the plane x m, Fig. l. Fig. 3 is a detached view of the torsional pintle. Fig. 4 is an end view of the same. Fig. 5 isa-perspective view of myhinge having wooden leaves. Fig. 6 is atransverse section in the plane yy, Fig. 5. Fig. 7 is a similar section in the plane z z, Fig. 5. Fig. S is adetached view of the torsional pintle used for the hinge. Fig. 9 is an end view ot' the same. Fig. l0 is a sectional face view of a hinge with a hollow pintle. Fig. 11 is an end View ot' the same.

Similar letters indicate corresponding parts.

In the drawings the letter A designates a hinge, the leaves a a. of which are made of sheet metal and provided with interlocking eyes b b', through which extends the piutle B. This pintle is made of metal wire, and after it has been passed through the eyes b b its ends c c are bent and fastened one end to the leaf a and the other to the leaf a. In theexample shown in Fig. lof the drawings the leaves a a are made ot' double layers ot' sheet metal, and the ends c c ofthe torsional pintle B are bent over twice, as shown in Fig. 3, so that they can be made to catch between the two layers ofthe leaves, as indicated in dotted lines in Fig. 1.

If the parts lto be hinged are made ot' wood, as shown in Fig. 5, the eyes b b are formed by means of staples, which are driven obliquely into the wood, (see Figs. G and 7,) so that the pintle B can pass through them, as shown in Fig. 5. rlChe ends c c ofthe pintle are simply bent and driven one into the part a and the other into the part a. The part a may represent the body of a box and the part a the cover, the two parts being connected by the torsional pintle and the two eyes.

ln both examples shown in the drawings the torsional pintle is applied to the leaves or parts a a ot' the hinge in such a manner that it has a tendency to throw said leaves open, and that if the leaves are closed, the pintle is twisted, so that when the leaves are released the torsional force of the pintlc throws the same open.

It will be readily seen from y the above description that my torsional pintle can be applied to the leaves a c of the hinge in such a manner that it has a tendency to keep said leaves closed, and that the ends of the pintle can be connected to theleaves'in a great many different ways which will readilysuggcst themselves to any mechanic of common sense.

It short heavy hinges are required, anumber of my spring-pintles may be employed in lthe same hole side by side, thereby giving the necessary elasticity, which a short and heavy spring-pintle would not give; or for heavy hinges a hollow pintle,d, maybe used, through which extends the torsional spring B, the ends c c of which are connected to theleaves c a of the hinge, respectively, as shown in Figs. 10 and 1l.

Heretofore springhinges have been constructed of two leaves and a met-al plate composing the torsional spring, which is attached at its ends to independent plugs, inserted in the ends of a spindle which connects the two leaves together, said plu gs being connected respectively with the two leaves ofthe hinge by means of transverse pins passing through the plugs and the eyes on the leaves. Springhinges have also been composed of two leaves, a connectingfpintle, and acoiled spring wound around the pintleandhavingitsends connected respectively'with the two leaves. Such con- IOO struction of hinges, however, not being myina hinge having interlocking eyes connected by vention, is not here claimed.

What I claim as new, and desire to secure by Letters Patent, is-

5 1. A spring-hinge combining in its structure two leaves having projecting eyes and a connecting torsional pintle consisting of a Wire extending through the said eyes and serving to connect the leaves and having its projecting 1o ends bent and attached directly to the said leaves ofthe hinge, substantially as described. 2. The combination, with the two leaves of a tube, of a torsional spring consisting of a Wire extending through the tube and having I5 its projecting ends bent and respectively acting on the leaves, substantially as described.

In testimony whereof I have hereunto set my hand and seal in the presence of two subscribin g witnesses.

GUSTAV L. JAEGER.
