HINGE.

SPECIFICATION formingpart of Reissued Letters Patent No. 10,024, dated January 31, 1882.

Original No. 200,657, dated February 26, 1873. Application for reissue filed July 5, 1881.

To all whom it may concern:

'Be it known that I,-WEsLnY HULL, of Fort Wayne, in the county of Allen and State of Indiana, have im'ented a new and useful Improvement in Spring-Hinges, which improvement is fully set forth in the following specification and accompanying drawings.

Figure 1 is a i'ront'view of a gate with hinges attached. Fig.2isafrontviewofhinge. Figs. 3, 4, and 5 are views of the hinge and detached parts, and Figs. 6 and 7 are detached views of a regulating-drum.

Like letters of rel'erence indicate like parts.

Myimprovementsconsistin the combination, with the leaves of a hinge, a rod serving to connect the said leaves, and a springadapted to impart a swinging motion to said leaves, of a lower bearing consisting of a circular shell extending from and turning with a socket affixed to one of the said leaves, wholly surrounding the rod, and receiving around it the end portion of the spring which acts upon the leaf of the hinge that is provided with said socket, thereby holding the spring away from said rod, and an inclined end bearing for the spring at the base of said shell. By these means I keep the spring in proper position parallel to the rod, and I at the same time keep it away from the rod.

The improvements further consist in the combination, with the leaves of the hinge and a rod whereby they are connected, of a spring adapted to impart a swinging motion to said leaves, and an upper hearing for the'end portion of the spring,impinging against the outer side of the same and holding it out of contact with the rod, the spring being exposed below said upper bearing. Through this combination of parts I am also enabled to keep the spring away from the rod and avoid its abrasion by the rod.

The improvements further consist in the combination, with the leaves of a hinge, a rod connecting them, anda spring for imparting a swinging motion to them, of a lower bearing consisting of a shell fitting inside one end of the spring, and an upper bearing acting on the outside of the other end of the spring to keep it away from the rod.

The improvements further consist in a novel combination of parts hereinafter claimed.

In the accompanying drawings, Grepresents the gate. A and B represent different leaves of the hinge. On leaf B is formed a catch, J, extending up near the socket D. .Upon the upper end of said socket is formed a thin circular shell, I, (see Fig. 4,) wholly surrounding the rod It, whereby the leaves are connected, and extending sufficiently from it to enter the lower end of spring E and keep it from commg in contact with rod R, thus avoiding friction. At the base of shell I, on the top of socket D, is formed an incline, terminating near catch J, designed to fit the lowerend of spring E and to form an inclined bearing for the spring, so as to equalize the pressure upon it with a view to keep the spring as straight as possible when compressed. For a similar purpose an incline is formed in the regulatingdrum F, to fit the upper end of said spring.

The rod R is rigidly secured to the leaf A, as seen in Fig. 3, detached view, and passes up loosely through socket D of leaf B, and extends above it sufficien tly to receive the spring E and regulating devices. The spring encir- 5 cles rod R and shell I. The extreme end of said spring, being bent out, engages catch J, by which it is held securely. The upper end of said spring E enters and fits within the lower end of the regulating-drum F. The mg ulating-drum at the upper end fits upon thev rod R, but may be turned thereon. The flange or rim of the drum F forms an outside upper bearin g, which impinges against the end portion only of the spring, and the latter is exposed beyond said upper bearing. Above it there is rigidly atfixed to the rod R a cap, 0, which is provided on the under side with notches or teeth, with which other notches on the top of the regulating-drum engage. As the rod R is connected to the leaf A of the hinge and the drum F and cap G are attached to this rod, the said drum and cap are attached to the said leaf A. The extreme upper end of said spring, being bent out, enters a recess, 0', 5 (see Fig. 6,) formed in the drum, by which it is held secure from turning. The upper end of the spring presses against the upper end of the interior of said drum, which is spirallyinclined to form an inclined end bearing for the upper end of the spring, to equalize the pressure upon it, in order that it may not be forced is kept from coming in contact with the rod B,

thus avoiding friction being exerted on the spring. The spring, by being compressed, acts upon the regulating-drum F to keep the notches on teeth on its upper end engaged with, the notches or teeth'on the lower end of cap 0, automatically holding said drum where itmay be moved in regulatingthetension ofthe spring to the required power to close the gate or door. Projections h h on the regulating-drum F form a hold for the hand, by-which to turn it in regulating the tension of the spring, to increase which it must be turned in the direction the spring is turned, when it will move over the inclines of the notches or teeth. WVhen desiring to lessen the tension of the spring it will be necessary to force down thedrum F until the notches or teeth become disengaged, thus allowing it to be moved when desired.

It is often necessary or desirable for certain purposes to have the gate remain open for the time being. For this purpose a projection or check, K, is formed on the socket D of leaf B, having a gentle incline, a, on the rear end and a steep incline, I), on the front. There is a projection, L, on the leaf A, having a gentle incline, c, in front and steep incline cl on the rear of it. Thus bothgentle inclines are opposite each other when the gate is closed, oii'ering but little resistance to projection K passing over the projection L in opening the gate. But when the gate is opened almost or entirely against the fence the steep incline of the projection or check K drops down that of the projection L, thus locking the gate open at a point to which it is seldom, if ever, opened in general .use, and thus giving ample protection to inclosures, and also afl'ording the conveniences lower hinge; or, if necessary, both may be spring-hinges. v

What I claim as my invention, and desire to secure by Letters Patent, is

1. The combination, with the leaves of a hinge, a rod serving to connect the leaves, and aspring adapted to impart a swinging motion to said leaves, of a lower bearing consisting of a circular shell extending from and turning with a socket affixed to one of the said leaves,

wholly surrounding the rod, and receiving around it the end portion of the springwhich acts upon the leafof the hinge that is provided.

'3. The combination, with the leaves of a.

hinge and a rod whereby they are connected, ofa spring adapted to impart a swinging motion to said leaves, a lower bearing consisting of a shell extending from and turning with a socket aflixed to one leaf, fitting upon the rod and receiving around it one end portion of the spring, and an upper bearing for the other end portion of the spring, impinging against the outer side of the same and holding it out of contact with the rod, the spring being exposed" between said lower bearing and upper outside bearing, substantially as specified.

4. The regulating-drum F, cap 0, and rod R, in combination with spring E, secured to the exterior end of socket D, substantially as and for the purpose set forth and described.
