To ail whom it may concern:

Be it known that we, HENRY P. Konus MEIER and GEORGE M. WALDORF, both ot Freeport, in the county of. Stephenson and State of Illinois, have invented certain new and useful Improvements in Spring-Hinges; and we do hereby declare the following is a full, clear, and exact description of the invention, that will enable'others skilled in the art to which it appertains to make and use the saine, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which forni a part of this specilication.

Figurel is a perspective :view of our iinproved spring-hinge. Fig. 2 is a vertical seetional view ofthe same. Fig. 3 is a peispective detail view of the sleeves removed from the hinge. Fig. 4 is a similar view of the sleeves, the spring, and the buttons separated; and Fig'. 5 is a view ofthe sleeves, showing a slight modification in the means for securing the spring and the buttons.

Similar letters of reference indicate corresponding parts in all the figures.

Our invention has relation to that class of spring-hinges in which the two leaves of the hinge are fornied with obliquely-projecting ears at the upper and lower ends of theiiinner edges, which ears are pivoted together, and which springs, arranged axial to the pintles of thehinge, are secured to the inner edges of the leaves, drawing them together; and it consists, fu rther, in the improved construction and coni binatioii ol' parts of such a hinge in which the spring isiseeured at its ends to two sleeves which surround the spring, and which turn upon each other, each sleeve, when used in connection with the leaves here shown, having a hook projecting from it, which engages an ear upon the inner edge of a leaf, all as hereinafter fully described and claimed.

In the accompanying drawings, the letters A A indicate the leaves of the hinge, which are provided at the ends of their inner edges with obliquely-projecting ears or lips B, which are pivoted together upon the pintlcs C, concentric to each other. The iniddles of the inner edges ot' the leaves are provided with wide slightly outwardly bent perforated ears or hails l), while otherwise the leaves are constructed similarly to the leaves of springhinges of this class. Two sleeves, E and F, inclose and completely cover the spring G, one sleeve, E, having a reduced inner portion, H,

upon which the other sleeve turns, and .the sleeves are provided at the inner meeting edges with ontwardly-projecting wide hooks I, when designed to be used with the leaves here shown, the ends of which project beyond the edge of the other sleeve, and which hooks engage the wide hails upon the inner edges of the leaves of the hinge. The outer edges ol' the sleeves'are provided with dianietricallyopposite notches J, and caps K, or buttons, titwith their inner reduced ends into the ends of the sleeves, having lips or projections L from the inner faces of their flanged outer portions, M, which fit into the notches J and prevent the caps from turning within the ends of the sleeves. The reduced inner portions ofthe caps are formed each with a perforation, N, which extends into a transverse recess, O, in the outer face of the cap, and the inwardlybent ends Q ofthe spring G lit into these perforations and recesses, and are retained in the saine. keeping the caps in their positions in the ends of the sleeves. that the spring and the caps will keep the sleeves together; and the caps ttting with their lips in the notches in the ends of the sleeves, the spring will be twisted when the sleeves are revolved upon each other, thus serving by its tension to draw the sleeves back into their original position, forcing the wide hooks toward each other. As these hooks are hooked into the ears at the niiddles of the inner edges of the hinge-leaves, the said inner edges will be drawn together in the saine manner as in spring-hinges ofasiniilar construction. After the leaves in opening have passed over the position in which they stand at right angles to each other, the spindle with the springs will be forced out froin a line with the,pintles of the hinge-ears, and the tension of the spring drawing upon the bails or ears ot' the leaves will tend to draw the leaves to stand in a po- It will thus be seen sition parallel with each other, so that at'ter the door has been opened beyond a certain distance it will be drawn open bysprings and held open by the springs.

It'desircd, the buttons or ca ps may he forined with a transverse groove, forining notches in the edges of the cap, into which groove the end of the spring may be placed; or the caps E hinge -leaves having lugs upon their inner may be heid together by means ot' an arial rivet, It, as shown in Fig. 5,while the ends of the spring are secured in notches S in the outer edges of the sleeves. It will thus be seen that the sleeves will serve as a easing for the spring, preventing any dust or dirt from entering into the spring and interfering with its Operative.- ness, and at the same time the sleeves will serve as means for conveying the power of the twisted spring to the hinge-leaves, as well as for holding the spring straight, and the vspring will hold all the parts ofthe spring mechanism of the hinge together, holding the caps together, which in their turn hohl the sleeves together.

From the foregoing description, taken in connection with the accompanying drawings, the construction, operation, and'advantages of our invention will be readily understood.

Our improved cover or casing for a doubleacting spring adds greatly to the durability,

' utility, and appearance of the springs.

Having thus described our invention, what we claim, and desire to secure by Letters Patent of the United States, is-

1. In a spring-hinge, the combination of hinge -leaves having lugs upon their inner edges', and two sleeves turni ng with their inner ends upon each other, and having hooks projecting from their sides, overlapping saidA sleeves in opposite directions and adapted to engage said lugs,with a spring inclosed within the sleeves and secured to the outer ends thereof.

2. In a spring-hinge, the combination of hinge-leaves having lugs upon their inner edges,with two sleeves turning with their ends upon each other, and having hooks projecting from their sides, aspring inclosed within the sleeves, and caps secured to the ends of the spring and to the ends of the sleeves.

3. In a spring-hinge, the combination of.

hinge-leaves having lugs upon their itineredges, and two sleeves turning with their inner 1 ends' upon each other, and having hooks projecting from their sides and engaging with said lugs, with a spring inclosed within the sleeves and secured to the outer ends of the sleeves, as and for the purpose shown and set forth.

4. In a sprng-hinge, the combination of l i l i edges, a sleeve having a reduced inner end, and having an outwardly-proiecting hook at the shoulder, formed bythe reduction, asleevc turning with its inner end upon the reduced portion ofthe other sleeve, and having a hook projecting outwardly from its inner end, said hooks engaging with said lugs, and a spring inclosed withi n the sleeves and secured to their outer ends with its ends, as and for the purpose shown and set forth.

5. In a spring hinge the combination of hinge leaves having lugs upon their inner edges, two sleeves turning with their inner ends upon each other, and having hooks projeeting from their sides and engaging with said lugs, removable and adjustable caps secured to the outer ends of said sleeves, and a spring inclosed by said sleeves and having its ends secured to said ca ps, substantially as and for the purpose set forth.

6. The combination of hingeleaves having lugs upon their inner edges, two sleeves turning with their inner ends upon cach other, and having hooks projecting from their sides and engaging with said lugs, and having notches in their outer ends, caps formed with recesses and perforations fitting into the outer ends of the sleeves, and having lips to engage with said notches, and a spring inclosed within the sleeves and having its ends inserted into the perfor-ations in said caps.

7. In a spring-hinge, the combination of two hinge-leaves having oblique ears at the ends of their inner edges pivoted together, and formed with wide perforated lugsor hails upon the middles of the inner edges, sleeves turning upon each other with theirinuer ends, and having wide hooks at their inner ends engaging said perforated lugs or bails, and a spring inclosed by the sleeves and having the ends thereofattaehed to said sleeves, as and for the purpose shown and set forth.

In testimony whereof we affix oui-signatures in presence ot two witnesses.
