March 7, 1933. M. F, SWERER ADJUSTABLE DOOR HINGE Filed March 11.

- INVENTOR MESwerer BY QM? .u.m;

ATTORNEY Patented Mar. 7, 1933 MILLARD F. SWERER, OF JAMESTOWN, CALIFORNII IA ADJUSTABLE DOOR. HINGE Application filed March 11, 1932'. Serial No. 598,153.

This invention relates to door hinges and particularly to a type of hinge especially adapted for use on wooden doors exposed to the weather and which constantly tend to expand or contract with changes in temperature and humidity conditions. In such cases the free vertical edge of the door is either liable to stick in the jamb or on the other hand to be so far away from the jamb that the catch members cannot cooperate.

The principal object of my invention is to provide an adjustable form of hinge for use under such conditions arranged so that the vertical edge of the door may be adjusted to and from the casing or jamb a certain distance as the expansion or contraction of the door may require. Such adjustments may be easily effected by anyone without any mechanical knowledge being necessary and without loosening or altering the position of the hinge screws and which would not tend to cause the screws to lose their hold in the wood.

I have also provided a means which may be associated with this hinge for adjusting the vertical position of the door relative to the casing.

A further object of the invention is to produce a simple and inexpensive device and yet one which will be exceedingly effective for the purpose for which it is designed.

These objects I accomplish by means of such structure and relative arrangementof parts as will fully appear by a perusal of the following specification and claims.

In the drawing similar characters of reference indicate corresponding parts in the several views:

Fig. 1 is a side view of the hinge as attached to a door and with the hinge adjusted to bring the adjacent vertical edges .of the door and jamb close together.

Fig. 2 is a sectional elevation of the hinge showing the same adjusted to separate the adjacent edges ofthe door and j-amb.

Fig. 3 is a sectional plan onthe line 3-3 of Fig. 1.

Fig. 4 is a similar view on Fig. 2.

Figs.

the line 4-4 of 5 and 6 are sectional plans of the hinge showing a different fitting of the eccentric members relative to each other andin different positions.

Referring now more particularly to the characters of reference on the drawing, the numeral 1 denotes the door engaging plate of the hinge which is disposed against the face of the door 2 and provided with vertically spaced circular sleeves 3 normally overhanging the amb. The jamb plate 4 of the hinge is secured to the edge of the jamb which faces the adjacent edge of the door and has other circular sleeves 6' disposed above and below as well as between the sleeves 3 in close association therewith.

Turnably fitted in the

sleeves

3 and 6 are

cylindrical members

7 and 8 respectively forming eccentrics as will be hereinafter seen.

- The sleeves 7 are concentrically alined with each other as arethe sleeves 8 with each other, but the two sets are ordinarily positioned outof axial alinement with each other.

This out of alinement is maintained by a hinge pin 9 preferably of hexagonal cross section which removably extends through all the members in eccentric relation to their centers. To hold the pin against removal it may have an enlarged head 10 on its upper end resting on the adjacent eccentric member 8. The lower end of the pin projects below so the bottom eccentric so as to be exposed for engagement with a wrench. By means of this arrangement it will be seen that on turning the pin one way or the other they relative positions of the hinge sleeves will be altered, causing the door to be moved one way or the other relative to the door jamb and casing.

The greatest possible adjustment is of course had when the eccentrics are mountedon the pin in diametral alinement with each other,as shown in Figs. 3 and 4 a half turn of the pin moving the door sleeves through their maximum movement.

:A lesser adjusting movement is bad by setting the eccentricson the pin in different positions relctive to the diametral lines, as shown in Figs. 5 and 6something which can be easilydone onaccount of the hexagonal form of thepin. During seasons when no adjustment is required and the door is disposed as originally fitted for instance, the eccentrics may be maintained in concentric alinement with each other by suitable readjustment of the pin in the eccentrics. This will maintain the hinge sleeves in alinement with each other when the door is closed and will give the same the appearance of the ordinary hinge. When swinging the door on the hinges the sleeves 3 turn on the corresponding eccentrics and to prevent possible turning'of the eccentrics 8 in their sleeves and the consequent loss of a previously set adjustment, I may hold one of said eccentrics 8 positively stationary in its sleeve by a set screw 11 or the like.

To enable a door to be adjusted vertically independent of its horizontal adjustment I may mount a bracket 12 on the door above the plate 1. A vertical bolt 13 mounted in a horizontal flange 14 on top of the plate 1 projects upwardly therefrom and is engaged by nuts 15 above and below the bracket. The screws 16 which secure the plate 1 to the door project through vertical slots 17 in the plate, so that on loosening the screws and turning the nuts one way or the other the door will be raised or lowered. After an adjustment of the door is thus obtained the screws 16 are of course again tightened up so as to relieve the bolt 13 of its load.

From the foregoing description it will be readily seen that I have produced such a device as substantially fulfills the objects of the invention as set forth herein.

While this specification sets forth in detail the present and preferred construction of the device, still in practice such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention, as defined by the appended claims.

Having thus described my invention what I claim as new and useful and desire to secure by Letters Patent is:

1. In a hinge, separate knuckles for the 7 leaves of the hinge, bushings in the knuckles,

the bushings in the knuckles of one leaf being turnable therein, and means connecting a l the bushings for disposing them in eccentric or concentric and non-turning relationship with each other selectively.

2. In a hinge, separate knuckles for the leaves of the hinge, bushings in the knuckles, the bushings in the knuckles of one leaf be ing turnable therein, and means connecting all the bushings for disposing them in different eccentric positions and in non-turning relationship to each other 3. In a hinge, separate knuckles for the leaves of the hinge, bushings in the knuckles, the bushings in the knuckles of one leaf be ing turnable therein, all said bushings having polygonal sided holes extending there- I through in eccentric relation to their axes,

and a pin of similar form removably engaging all said holes.
