HINGE.

SPECIFICATION forming part of Letters Patent No. 633,075, dated September 12, 1899.

Application filed March 13, 1899.

To all whom 170' ntaz concern.-

Be itknown that I, GEORGE W. OLUM, a citizen of the United States, residing at Colum- Ohio, have invented new and useful Improvements in Spring-Hinges for Screen-Doors, of which the following is a specification.

My present invention relates to certain new and useful improvements in hinges, and more particularly to that type or class of hinge es pecially adapted for hanging screen-doors.

In mounting screen-doors it has been a common practice to secure the hinges to the outer surface of the doonframe and to introduce a block beneath one of the leaves of the hinge of the same depth or thickness as that of the screen-door in order that room may be left for the door to swing upon the pivots of the hinges. This block not only presents an unsightly appearance, but necessitates the construction of the same prior to the application of the hinge to the door and its frame.

It is the prime object of the present invention to avoid the use of the separate wood block referred to, to improve the class or type of hinges designed particularly for hanging screen-doors, and to so construct a hinge wherein one leaf thereof is provided with an integral offstanding flange around the outer edge thereof to form a practically hollow leafbody and wherein the outer faces of the two leaves will normally lie in the same plane, so as topresent a neat, compact, and attractive appearance. These objects are accomplished in the manner and by the means hereinafter described and claimed, reference being made to the accompanying drawings, in which Figure 1 is a front elevation of a springhinge for screen-doors embodying myinvention. Fig. 2 is a top plan view of the same, parts of the screen-doorand door-frame being indicated by dotted lines; and Fig. 3 is a detail perspective view, looking at theinside of one of the hinge-leaves.

In order to enable those skilled in the art scribe the same in detail, referring to the drawings, wherein the numerals 1 and2 indicate the two hinge-leaves having at the ends of their inner edges the overlapping perforated

cars

3 and 3, through which the hinge- Serial No. 708,906. on) model.)

pintle 1 passes. The

outer edges

8 and 8 of the leaves are triple-curved or scalloped, and the leaf 2 is castintegralat its inner edge between the ears 3 with an arched or curved spring-housing 4, behind which the hinge spring 7 is located. The two hinge-leaves normally lie in the same plane on their outer surfaeesthat is, when the screen-door is closedand the leaf 1 is formed integral with a triple-curved or scalloped flange 6, which stands off at right angles to the body of the leaf and extends continuously along the outer edge and the ends thereof,following the triplecurved or scalloped contour of the outer edge of the leaf. This construction forms a pram tically hollow leaf 1, and although it is of considerable depth or thickness its weight and cost of manufacture are not materially increased owing to the fact, as above stated,

that the leaf is practically hollow, and this I consider to be an important feature of the invention, especially from a practical point of view, since the weight of the leaf is decreased and the cost of production consequently lessened, which would not be the case if the leaf were made solid throughout. This offstanding continuous flange is of a depth or width the same as the depth or thickness of the screen-door 5, to which the hinge-leaf 1 is secured by screws passed through screw-holes formed between its inner edge 9 and the flange 6 on its outer edge.

To hang the screen-door, the inner edge of the flange 6 is made to bear against the doorframe, so that the leaf 2, while lying in the plane of the leaf 1, is in a position to bear against the screen-door, as in Fig. 2. The two leaves are secured by screws passing through screw-holes therein, as is obvious. The screen-door is then susceptible of being opened and closed in the same manner as if in the absence of the flange 6 a separate block were inserted under the hinge-leaf 1 to place the other leaf in proper position to be secured to the door; but the bad or unsightly appear-- ance of such block is avoided.

The flange is an integral permanent part of the hinge and does not materially increase its cost. In fact, it is less expensive and obviously more convenient than the separate wood block referred to, and as the flange follows the curvilinear outer edge and ends of the hinge-leaf 1 the hinge preserves its neat, compact, and ornamental appearance.

I have herein shown and described my invention as applied to spring-hinges; but I do not wish to be understood as limiting myself to this specific type of hinge, for it will be obvious that the otfstanding flange may be formed upon hinges of other character without departing from the spirit of myinvention.

I do not broadly claim a spring-hinge having two leaves normally lying in the same plane and connected by a pintle; nor do I broadly claim a spring-hinge having two pivoted leaves, one of which is formed with an arched spring-housing at its inner edge; nor do I claim a hinge composed of two leaves normally lying in different planes and one having at its inner edge a flange at right angles thereto for connecting said leaf with the hinge-pintle, and, finally, I do not claim a hinge wherein one leaf is composed of a plate having an extension at right angles therewith to which the other leaf or plate is pivoted.

Having thus described my invention, what I claim is 1. A spring-hinge for a screendoor, eonsistiug of two leaves normally lying in the same plane and having overlapping cars at the ends of their inner edges through which a pintle passes, one leaf formed integral with a flange offstanding from its outer edge and extending continuously along said outer edge to provide a practically hollow leaf member, the screw-holes of the flanged leaf lying between its inner edge and the said flange at its outer edge, the flange being constructed of a depth or width the same as the thickness of the door to be hung, substantially as described.

2. A spring-hinge for a-screen -door, consisting of two pivoted leaves normally lying in the same plane, one formed integral with a flange offstanding from its outer edge and around its opposite ends, whereby a hollow leaf member is formed, and the other formed at its inner edge with an arched spring-housing, said flange constructed ofadepth or width the same as the thickness of the door to be hung, substantially as described.

3. A screen-door hinge, consisting of two leaves having scalloped outer edges and each provided at the upper and lower ends of its inner edge with two perforated ears through which the pintle passes, one leaf having its scalloped outer edge formed integralwith a scalloped flange extending continnouslyalong said outer edge and around the opposite ends of said leaf to provide a practically hollow leaf member, and constructed of a depth or width the same as the thickness of the door to hear at its inner edge against the door-frame while the other leaf bears against the door and the outer surfaces of both leaves lying normally in the same plane, substantially as described.

4. A hinge for screen-doors, consisting of two pivoted leaves, the outer faces of which normally lie in substantially the same plane, and one of said leaves being formed with an integral otfstanding flange extending along the outer edge and opposite ends thereof to provide a practically hollow leaf -body, the said' flange being constructed of a depth or thickness the same as the thickness of the door to be hung, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

GEORGE IV. CLUM.
