A CORPORATION SPRING-HINGE.

SPECIFICATION forming part of Letters Patent No. 734,446, dated July 21, 1903. Application filed November 18,1902 o ri No. 131,822 (No model.)

To all whom it may concern:

Be it known that I, HARRY J. VALENTINE, a citizen of the United States of America, and a resident of Cleveland, Ouyahoga county, in

the State of Ohio, have invented certain new and useful Improvements in Spring-Hinges, of which the following is a specification.

This invention relates to spring-hinges, especially of the class which are used for light doors, such as screen-doors; and the objects of the invention are to provide a spring-hinge which is durable and economical, which consists of the fewest possible parts consistent with a satisfactory hinge of the described class, and to hold the parts firmly together; further, to provide means for adjusting the tension of the spring of such class of hinges.

To these ends my invention consists of sev-' eral features of construction and combinaac tions of parts, to be hereinafter described and then claimed.

In the accompanying drawings, Figure l is a front elevation of myimproved spring-hinge. Fig. 2 is a longitudinal sectional View taken in plane of the hinge. Fig. 3 is a transverse section on the line 3 3, Fig. 2. Fig. 4is a perspective view of one of the end tips of the hinge. Fig. 5 is a front view of a modification, and Fig. 6 is a section of the spring-ad 3o justing portion thereof.

Referring to the drawings Figs. 1 to 4, the simplest form of hinge shown comprises a pair of leaves A A, which are provided each with ears or lugs a a, respectively at opposite ends, and the inner edges of the leaves are bent upwardly to form flanges a to partially-inclose the spring 0. The leaves are preferably made of sheet metal and are counterparts one of the other, they being fixed to- 0 gether by means of preferably hollow sheetmetal tips 15 B, which form pintles on which the leaves of the hinge pivot. The leaves are placed together so that their ears overlap, as shown clearly in Fig. 2, the ear of leaf A at one end of the hinge being outside of the adjacent ear of the leaf A, while at the opposite end of the hinge the ear of the leaf A lies outside of the ear of leaf A. The ears are provided with suitable openings to receive 5o the pintl'e-tips, and into the openings of the locking-teat d. is provided with a diametrical longitudinallyextending slot 1). The helical spring 0 occuipies the space between the flanges a of the .the said slot. the tip B is driven into the registering openouter'ears of the respective leaves A A there projects from each ear, preferably in the plane thereof, at one end of the hinge a locking teat or projection 01 and at the other end a Each of the pintle-tips B B leaves, one end thereof abutting against the ear of the leaf A at the corresponding end of the hinge, while the other end of the spring abuts against the ear of the leaf A at the opposite end of the hinge. The opposite ends of the spring are bent diametrically across the spring at 0 C The pintle-tip B is driven through the registering openings in the ears at one end of the hinge, so that the teat or projection d will enter the slot of said tip and interlock with the same, the adjacent end of the spring being also caused to engage with At the other end of the hinge ings of the ears, the teat or projection dbeing caused to enter and interlock with the slot of the said tip B and the adjacent end O of the spring being caused to engage with the slot-'of the tip also. When the tips. are driven fully home, the parts of the springhinge are united, one end of the spring acting on one leaf and the other end of the spring acting on the other leaf. Each leaf bears at the opposite ends of the spring-hinge a tipin one case the tip B and in the other case 'the tip Band when the door towhich the hinges are applied is swung open the leaf on p the door acts to Wind up the spring and put it under tension,'so that when the door is released the spring will close the same. The tips B B are identical, and it will be seen thatin the entire spring-hinge described there are only three parts which differnamely, a leaf, the spring, and a tipthe two leaves being counterparts, as also the two tips. The exposed ends of the tips are rounded off to impart a finish to the ends, or theymay be stamped in any suitable shape. I V

In the modification shown in Figs. 5 and 6 the same reference-letters apply to corresponding parts, the only difference being at one end of the hinge. Here an elongated pin- ICO tle-tip E is not keyed to one of the leaves, but may turn in one pair of cars a a, it being forced home by the endwise expansion of the spring 0. The pintle-tip E has a slot 2, which receives the adjacent bent end of the spring C and also a head or flange e, against which the end coil abuts. Between the bead e'and the adjacent ear a the, pintle-tipE has an annular series of holes f, so that the pintle-tip may be turned like acapstan bya nail or the equivalent and the tension of the spring be adjusted, this tension being held by the abut ment upon the leaf A of a looking-pin F, inserted in one of the holesf.

What I claim as new and of my invention 1. In a spring-hinge, the combination of similar leaves provided each with equidistant ears at opposite ends, the ears being placed together in pairs so that atone end the ear of one leaf is at the outside and at the other end the ear of the other leaf is at the outside, tips inserted in said ears, and a helical spring arranged between the leaves and the two pairs of ears, and the ends of the spring being engaged with the tips, substantially as set forth.

2. In a spring-hinge, the combination of the leaves provided with ears at opposite ends having registering openings, tips inserted into the registering openings of the respective ends of the hinge, one tip being attached to move with one leaf at one end of the hinge, and the other tip engaged with the ears at the other end of the hinge, and a helical spring arranged between the leaves and the ends thereof being suitably engaged with the inner ends of the tips, substantially as set forth.

3. In a spring-hinge, the combination of the leaves provided with cars at each end having registering openings, a teat or projection on one of the leaves at one end of the hinge, projecting into one of the openings, slotted tips inserted into the registering openings at opposite ends of the hinge so that the teat or projection enters the slot ofthe appropriate tip to lock the tip against relative rotation to the leaf to which it is applied, and a helical spring arranged between the leaves with its ends in engagement with the slots of the tips, substantially as set forth.

4:. In a spring-hinge, the combination of leaves provided with a pair of adjacent perforated cars, a teat or projection extending inwardly from one ear, and a pintle-tip inserted in said ears, and having a slot at its inner end receiving said teat, said pintle-tip projecting beyond said ears, substantially as set forth.

5. In a spring-hinge, the combination of leaves provided with ears at the ends only having registering openings, pintle-tips inserted in the openings at both ends of the hinge, one of said tips being fast to one of the leaves at one end of the hinge, and the tip at the other end being provided with a series of tension-holes, a locking-pin engaged in one of the holes and abutting upon one leaf, and a helical spring between the leaves and the ears, engaged with both tips, substantially as set forth.
