PATENT G EEICE.
OLIVER M. CHESNEY, lOF TOPEKA, KANSAS, ASSIGNOR ONE-HALF TO CHARLES R. FREDERICKSON, -OE KANSAS CITY, MISSOURI.
SPRING-HINGE.
SPECIFICATION forming part of Letters Patent No. 741,626, dated October 20, 1903.
Application led October 20, 1902. Serial No. 128,029. (No model.)
To all whom it may concern:
Be it known that I, OLIVER M. CHEsNEY, a citizen of the United States, residing at Topeka, in the county OfShaWnee and State of Kansas, have invented ynew and useful Improvements in Spring-Hinges, of which the following is a specification.
My invention relates to spring-hinges; and my invention consists' in constructing the frame and the spring of a single piece of wire and forming the leaves of' 'stamped metal and attaching them to the wire frame, as hereinafter described.
Referring now to the accompanying drawings, Figure lis an elevation of the preferred form of hinge embodying my invention. Fig. 2 is a section of one of fthe leaves, Vtaken on line II Il of Fig. l. Fig. 3 is a bottom plan view of the hinge. Fig. 4 is a transverse section of one of the leaves. Fig. 5 is a partlysectional elevation of a modified form of the invention.
Referring to Figs. 1, 2, 3, and 4, 1 desig nates as a whole the wire which forms the frame 3 3 and the torsion-coil 4. Said coil is formed by winding upon a mandrel the middle portion of the wire after first forming a small turn Ll, having the "same interna] diameter as the diameter of the wire,
used. The upper end of the coiled portions. is reduced in diameter, as shown, to form an opening of about the same diameter as that of the wire itself. The lower end of the coil is abruptly reduced in diameter, thereby forming a small turn 4.', which is adapted toY form a. bearing for the wire 1, near the lower end thereof.
be free to wabble within the lower end of the coil, and the door supported by the hinge (or hinges) would sag or work loosely. The course of the Wire, beginning with, e. g., the lower end, is to the left, then up, then to the right, forming the france3 of the lefthand leaf, thence downwardly and spirally, forming the coil 4, thence to the right, then up, then to the left, forming the frame 3 of the right-hand leaf, and down into the upper or smaller end of the coil.
Each leaf 6 is a rectangular piece of sheet metal and is secured to the wire frame 3 by bending its ends around the upper and lower portions of the frame, as shown. The leaves If it were not for this small turn 4' of the wire, the end of the wire would.
are provided with screw-holes?.- The longer edges of each leaf '6 arel bent outwardly,
forming iianges 6', which stiden or strengthen` thimble, so that a iiange is provided, which being pressed upon the end of the coil prevents the thimble from being pushed too far into the coil. In the heads of the respective thimbles are central openings just large enough to admit or pass the respective ends of the wire l2.- Thus the ends of the wire are pivoted in the heads of the thimbles 9 instead of in the endsof the coil, as in the preferred form described heretofore. 1313 are the leaves of the hinge. These leaves are stamped out of sheet metal, and they are securedA to the sides of the hinge by bendingv l'their ends around the upper and lower portions thereof. The thimbles 9 are held lin the ends of the coil 8 by the rigidity or stiffness of the frame -or sides of the hinge.
Having now fully described nmy invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-
A spring-hinge comprising a frame and a torsion-coil, both frame and coil being formed .of a'single piece of wire, said coil being formed by the middle portion of the wire, a
thimble within each end of said coil, each thimble having a head provided witha central opening, the ends of the wire passing through said openings respectively, and sheetmetal .leaves secured to the frame of the hinge'by having their ends bent around the upper and lower portions of said frame, substantially as described.
In testimony whereof I affix my signature in the presence of two witnesses.
