HENRY F. KEIL, OF NEW YORK, N. Y.

SPRING- HINGE.

SPECIFICATION forming part of Letters Patent No. 387,421, dated August 7, 1888.

Application filed March 30, 1888.

To cLZZ zar/"tom it may concern..-

Beit known that l, HENRY F. KEIL, ofthe city, county, and State ofNew York, haveinvented a new and Improved Spring-Butt, of which the following is a full, clear, and exact description.

My invention relates to a springbut.t, and has for its object to provide a butt of simple, durable, and effective construction, whereby the tension of the spring may be regulated by the manipulation of one tip, and wherein the spring will be completely concealed and the device have the outward appearance of an'ordinary butt.

The invention consists in providing a butt with tubular pins or pintles,the combination, with said tubular pintles, ofa revolving spindle, the combination, with a pintle and spindle, of a spring, and iu the construction and combination of the several parts as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of the butt. Fig. 2 is a central vertical section thereof. Y Fig. 3 is an elevation of one section of the pintledetached, the spring being partly in section. Fig. 4 is a transverse section on line4 4 of Fig. 1, and Fig. 5 is asimilar section on line 5 5 of Fig. 2.

ln carrying out the invention, leaves 10 are provided, having attached thereto ordinary knuckles 1l, adapted to interlock in the ordinary manner. Upon one leaf, at the upper end, at theintersection of said leaf with the upper knuckle, a vertical post or projection, 12, is cast integral therewith, for a purpose hereinafter stated, and in thelower knuckle, upon the inner side at the bottom, a recess,13, is produced.

The pintle 14 is tubular and divided into two sections, 15 and 16, each section being provided with a tip, 17, adapted to surmount the knuckles at top and bottom. The pintle-section 15, which is the upper section, is provided with a spindle, 18, cast integral therewith or otherwise secured thereto, which spindle projects from the under side of the tip or head Serial No. 269,004. (No model.)

17, vertically downward'within the center of the section and out therefrom. Below the lower end of the upper pintle-section, 15, a

second section of spindle 19 is secured to the aforesaid upper spindle-section, 18.

The lower spindle-section is adapted to revolve upon the upper spindlese'ction, which is preferably accomplished in the following manner: The end of the upper spindlesection is provided with a longitudinal aperture, 20, and the lower spindle-section with a post, 21, adapted for insertion in the aforesaid aperture 20. The post having been entered in the aperture, the walls of the upper spindle-section are depressed in any suitable manner, as shown at 22 in Fig. 5, and also in Fig. 2, whereby the outer depression of the metal forms projections in the wall of the aperture 20, which projections enter an annular groove, 23, produced upon the surface of the spindle post 2l, as best illustrated in Fig. 2.

The lower spindle section, 19, is of a length .sufficient to pass through the lower pintlesection, 16, and extend a distance upward in the tip or head 17 of that section. Both sections of the spindle are of the same contour, which is polygonal, and the lower spindle-section is securely held in the lower pintle-section by entrance in an aperture, 24, produced in the inner surface of the lower head, as clearly shown in Fig. 2, the aperture 24 being so shaped as to be perfectly adapted to the contour of the spindle and prevent the same from turning.

Thelower pintlesectiou, 16, below the flange or collar 25, which normally rests against the lower knuckle of the leaves, is provided with a longitudinal post, 26, of a contour similar to the contour ofthe recess 13 in the said lower knuckle, the post or projection 26 being adapted for entrance in the said recess, as will be hereinafter set forth.

The neck of the lower tip orhead, 17, is provided with aconical diametrical aperture, 27, which aperture is adapted to register with an aperture,28, in the lower spindle-section, when the said spindle section is in its normal position, as indicated in Fig. 2.

The spring 29, adapted to surround both sections of the spindle, is a closelycoiled spring, the wire at each end being bent to the IOO contour of the spindle, the body ofthe spring being circuler. It will thus be seen thut when the spindle is passed through the spring the seid spring is prevented from turning upon the spindle, but Will be contracted when the spindle is rotated.

In the `collar 30 ol' theupper tip or houd,

which corresponds to the llungc or coller 25 of the lower tip, e series ol" apertures, 31, uro drilled or otherwise produced, which upertures are adapted `for the reception of u pin,32.

The severulknuekles of the leaves having been fitted to place, the spring 29 is passed over the spiudleinto the upper pintle-section,

15, to u bearing against the under side of the head. The upper spindle-section, the spring,

und the spindle ure then passed down through the several knuckles until the flange 30 rests upon the surface of the upper knuckle. The loWer pintieseetion, 1G, is then introduced in the knuckle over the spring und pressed upward to un essentiel contact with the upper pintleseetion, the lug or projection 2G .upon the seid lower pintle-sretion being inside to enter the recess 13 in the lower knuckle.

Thenpcrture in thelower section ofthe spindle-section will now liuve been broughtin ister with the aperture 28 in the neck of the lower heed, 17, the lower end of the spindle having been entered into the recess 24- iu the said lower heud. 1When this adjustment hns been accolnplislied,the pin 83 is passed through the apertures 2S und 27, which provides un auxiliary menus of holding the lower spindlesection in rigid contact with the lowerpiule section, us clearly shown in Fig. 2.

To exert a tension upon the spring,ihe hinge having non heen placed together, it simply becomes necessary to grasp the upper tip, 17, und revolve the sume, whereupon the upper spindleseetion revolving upon the lo iver spindle-seelion,\vl1ich is stationary, contracts the spring, and when the spring has been sufficicntly contracted to suit the operator the pin 32 is entered in the aperture 31, adjacent to the lug 12, und the heed is released, the parts being held in the aforesaid position by the engagement of the seid piu 32 with the seid projection l2, us clearly shown in Fig. l.

Having thus fully described my invention,I cleiin us new und desire to secure by Letters Patentl. In u spring butt-hinge, the combination, with the leuves und knuckles thereof, of a sectional tubulur pi ntle, u spindle connecting said sections, und u spring surrounding the spindle within the sectional tubular pintle, substantiully es herein shown end described.

2. ln u spring butt-hinge, the combination, with the leaves provided with knuckles, of u sectional tubular pintle, u sectional andjointed spindle connecting the suid sections, und a spring surrounding the spindle Within the tubulnr piutle, substuntiully es herein shown und described.

3. In u butt-hiuge,the eoinbinutio1i,\vith the leaves und knuckles tliereooi'nsectional tubulur pin or pintle, u divided spindle heving one section revolving upon the other,tl1e outer ends of which spindle ere held in the respective pintle-section, und e spring held upon seid spindle und controlled thereby, substuutiully us shown und described.

4. In e. spring butthinge, the combination, willi the leuves '.ind knuckles, of :i sectional tubular pin or pintle, u divided spindle huving one section revolving upon the other, the outer ends of which spindle ure held in the respective pintleseetions, u spring held upon Suid spindle und controlled thereby, und ineens, substuntiully es shown and described, for retaining the spring in n. contracted posi tion, us und for the purpose specilied.
