ADJUSTABLE HINGE Filed oct. 10, 1950 Rober @Polso/z Mami '25 ATTORNEYS Patented Nov. 3, 1953 UNITED STATE TENT OFFICE This invention relates in general to improvements in a double-acting spring hinge and check assembly for swing doors.

One object of the invention is to provide novel mounts for the upper and lower vertical pivots or spindles of the hinge assembly; such mounts being arranged to permit the spindles-by easy and convenient manipulation of readily accessible parts-to project said spindles for placement of the door inthe door opening in hinged Working position, or to retract the spindles to remove the door.

Another object of the invention is to provide a hinge assembly for swing doors, which includes a double-acting, spring actuated closure, and check mechanism of novel construction and function.

A further object of the invention is to provide a hinge assembly, for swing doors, which is simple to install and adjust after installation.

An additional object of the invention is to provide a hinge assembly, for the purpose described, which is designed for ease and economy of manufacture.

Still another object of the invention is to provide a practical and reliable hinge assembly for swing doors, and yet one which will be exceedingly effective for the purpose for which it is designed.

These objects are yaccomplished by means of such structure and relative arrangement of parts as will fully appear by a perusal of the following specication and claims.

In the drawing:

Fig. l is a foreshortened elevation of a door mounted by means of the improved hinge assembly; the upper and lower spindle mounts being in section.

Fig. 2 is a cross section on line 2-2 of Fig. l.

Fig. 3 is a plan View, partly broken away, of the spring actuated closure mechanism.

Fig. 4 is a sectional elevation of said closure mechanism, as in use.

Referring now more particularly to the characters of reference on the drawing, the improved hinge assembly is adapted for use in connection with a swing door, indicated generally at I, adapted to be mounted for to and fro swinging movement in a door frame which includes a door jamb 2 upstandingY from the floor 3, and a header 4. y Y

'I'he upper and inner corner of the door I is pivotally mounted in connection with the header 4 as follows:

A vertical sleeve 5 is disposed in a bore formed in the door I from its upper edge, and an upper, vertical spindle 6 is initially slidably disposed in said sleeve 5.

The upper, Vertical spindle 6 normally projects a distance above the upper edge of the door I and engages in a matching socket 'I of a socket plate 8 secured horizontally to the under side of the header 4.

A rotary shank il extends through the door horizontally from its inner edge; such shank at its inner end being formed as a pinion I0 which projects into the Vertical sleeve 5 and runs in mesh with a rack II formed on the spindle S intermediate its ends.

At its outer end the rotary shank s includes a slotted head I2 which seats ush in a socket I3 of a plate I4 attached to said inner edge of the door. The shank 9 is rotatable but axially removably secured with respect to the socket I3. By rotating the head I2 with a screw driver the upper Vertical spindle 6 may be caused to move between a retracted and an advanced or projecting position.

When the door I is being installed, the spindle E is initially in a retracted position, and after the door is disposed in place said spindle is run out or projected, in the manner above described, to engage in the socket l; all by the simple manipulation of the head I2 with `a screw driver.

The above constitutes the upper spindle mount of the hinge assembly; the lower spindle mount comprising the following:

The lower spindle is indicated at I5, and is in substantially vertical alinement with the upper spindle 6; being adjustable, however, in the manner as will hereinafter appear.

The lower spindle I5 is relatively short and projects upwardly in matching relation into a socket member Iii; there being a slot and screw arrangement I 'I exposed below the door, whereby the lower spindle I5 may be held up within the socket or permitted to drop into a depending position, and as is necessary in connection with the mounting of the door in place, as hereinafter set forth.

The socket member it is exteriorly rectangular and engages in a horizontal inverted U-shaped guide channel I8 which is recessed upwardly into the door I from its lower edge at the inner corner; such guide channel including, at its outer end, a vertical attachment plate IQ recessed into the rear edge of the door.

The channel I8 and attachment plate I9 are secured in place by screws, as shown.

The socket member I6 includes an ear 2G which upstands through a slot 2| in the top of the inverted guide channel 8, and a horizontal screw rod 22 is threaded through such ear, being rotatably but non-axially movably mounted in connection with said guide channel la above the same, as in an eye member '23 threaded into the web of said channel. At its outer end the screw rod 22 is formed with a slotted head 24 which is flush with the attachment plate i9.

Upon rotation of the slotted head ZAby means of a screw driver, with resultant turning of the rod 22, the socket member I9 is caused to move in the guide channel IS, whereby to alter the distance of the spindle I from the rear edge of the door. The purpose of this adjustment is of course to attain true vertical ali'nement of the rear edge of the door relative to the door jamb 2.

The lower spindle I5 engages, when the door is in place and the spindle is lowered as previous- -ly described, in .detachable connection with ia .double-a,cting, spring .actuated .closure .mechanism, indicated generally at 25, and which-lacon- .structed in detail asfollows:

The closure mechanism 2.5 comprisesa V,top plate 25 which overlies lan opening .3.1 precut in ythe floor below the lower .inner corner .of the door I; said plate being secured to the floor .by screws, as shown,rand to the door jamb 2 through the medium of upstanding Y.ears 2,8 screwed to said jamb.

A .case 29 is fixed in .connection `with the top plate .26 .and .depends .through the floor .opening 21, and a vertical axis rotor 39 isdisposed in .such

case; said rotor including .a lower vtrunnion 3! and an Vupper trunnion 32 journaled Vin the bot- .tom ofthe case and insaid plate 25, respectively.

rEhe trunnion .3L-2 is formed with an upwardly opening socket 33 `into which the .lowerfspindle l5 normally seats; .saidspmdle and ,socket .being of 4matching nonpcircular .configuration whereby when .thedoor vl swings one way `or theothercorresponding part-circle rotation is imparted to .the :rotor Nlill. The lower spindle l5 .isadjnsted .downwardly Vby the slot and screw `arrangement Il so `that suchspindle seats in the .

socket

3,3, .as aforesaid.

The rotor 3d is formed with a horizontal .cross bore .34 at .right angles to .the .closed .position of the door` l, and opposed .plnng-ers 35 project Linto -the `cross bore .3A from opposite ends; Ysuch plungers being socketedat Atheir .inner .end portions and telescopic, having a heavy-.duty cornpression spring 3.6 engaged inthe socketed portions of-said telescoped plungers to `urge the latter apart.

At their outer ends the opposed .plungers 35 are each formed witha fork .3.1, .which orkstraddles a horizontal elliptical .track 38' formed in the case 29 about the vertical walls thereof.

Rollers ,39 are journaled in the forks 31 Vand ride the inner edge .of said Yelliptical track 3 8.. AS the forks 3l' straddle the track 38 the rollers 39 are always maintained in proper ,engagement lwith said track, without the necessity of any keyway or guide means ,between the plungers 35 and lthe rotor 36.

The major axis of the elliptical track 38 is parallel to the normal position of the door l so that under the action of the spring 2G the opposed plungers 35 normally seek the position shown in Fig. 3, whereby to maintain the `swing door I in its closed position. However, `upon opening of said swing door l 90 in either direction from its closed position, the rollers 39 snapengage into notches 4l] at opposite ends of the elliptical track 38, thereby releasably holding the door in an open position.

With the above described hinge assembly a swing door may be readily initially installed in place or subsequently easily removed; the door when in place being under the effective control of the double-acting spring actuated closure mechanism. While the mounts for vthe upper and lower spindles 5 and I5, respectively, are of simplie fied structure, they nevertheless provide for iq-uick adjustment of said spindles between a re- Ttracted position which permits the door to be removed, and an advanced or projected position withthedoor then subject to the control of the mechanismzi From the foregoing description it will be readily seen tthat there has been produced such a device as substantially fullls the objects of the invention, .asset forth herein.

While .this `specification-sets forth in detail the present and preferred construction .of thedevce -stillin practice suchdezviations from such detail `may .be resorted .to as .do not form .a departure from .the spirit of the invention, v.as dened by .the appended .claims.

.Having thus ,described the invention, -the'lfollowing .is claimed .asenew `and useful, `and .upon which Letters Patent are desired:
