SPRING HINGE Filed Nov. 10. 1931 INVENTOR I (John 0. Olo
16 2O 7 UM ATTORNEY Patented Dec. 27, 1932 UNITED STATES JOHN 0. OLSON, F SEATTLE, WASHINGTON SPRING HINGE Application filed November 10,1931. Serial No. 574,127.
My invention relates to spring hinges and certain objects of the invention are to provide a hinge comprising a pair of leaf members one of which is provided with arms that are wider than the arms of the other whereby thick doors may be hinged to comparatively thin casings. Another object is to provide a raising member whereby my hinge may be used for hinging a door to a casing of equal thickness with the door. Further objects are to provide a hinge one leaf of which is provided with a single cylindrical spring containing member and the other leaf is provided with a stiffener flange thus materially increasing the strength of the hinge and providing bearing means for the ends of the spring.
With the above and other objects in view which will appear as the description proceeds, the invention consists of the novel construction, adaptation, combination and arrangement of parts hereinafter described and claimed. These objects are accomplished by devices illustrated in the accompanying drawing; wherein Figure 1 is a view in rear elevation of the hinge with a part broken away; Fig. 2 is a view in rear elevation of the channeled raising member that is used when the hinge is 39 secured to a door and casing of equal thickness; Fig. 3 is a view in horizontal section taken on a broken line 3-3 of Fig. 1 and showing the hinge secured to a door that is thicker than the casing; Fig. 4 is a top plan view showing the hinge secured to a door and easing of equal thickness and wherein the raising member is used; Fig. 5 is a view in perspective of the hinge leaf having the stiffener flange; Fig. 6 is a view in perspective of the hinge leaf having the cylindrical container for the spring; Fig. 7 is a view in elevation of the pintle; and Fig. 8 is a view in elevation of the coiled spring.
Referring to the drawing throughout which like reference numerals indicate like parts, the numeral 5 designates the hinge leaf having a cylindrical spring container memher 6 which is secured between ears 7 that are formed on arms 8 which are either bent at right angles to the ends of said leaf or are braised, welded or otherwise secured at right angles thereto. The inner edge 9 of said leaf forms a longitudinal shoulder. The cylindrical spring container 6 is provided'with upper and lower slots 10 and llrespectively for the ends of the spring. The ears 7 have the usual holes 12 for the pintle and the leaf 5 has the usual screw holes 13.
. The other leaf 14 of the hinge is provided on its ends with arms 15 which may be bent at right angles to said leaf or secured thereto at-right angles-in any desired manner. Said arms are somewhat wider than the arms 8 thus providing abutments or offsets 16 and the arms terminate in ears 17 that respectively fit over the ears 7 of the arms 8. Holes 18 are provided through said cars 17 which register with the holes 12 of said ears 7 and a pintle 19 is installed through all of said holes thus pivotally retaining the two hinge members together as will be understood. .The abutmentsor offsets 16 of the arms 15 have shoulders-20 thereon whichare formed by bending small metal projections thereon inwardly as most clearly shown in Fig. 5. The inner edge portion of the leaf 14 is bent inwardly at right angles to form a stiffener flange 21. 4
hen the two hinge members are pivotally connected by the pintle 19 the shoulders 20 .80 abut against the inner edge 9 of the leaf 5 thus retaining said leaf in parallel relation with the leaf 14. A coiled spring 22 is in.- stalled within the cylindrical container 6 and has its upper end 23 projecting through the slot 10 and bearing against the back of the leaf 5. The'lower end portion 24 of said spring projects through the slot 11, bears against the outer edge of the stiffener flange 21, and is bent inwardly to a termination against the back of the leaf 14. Said leaf is provided with the usual screw holes 25.
Referring to Fig. 3 of the drawing, it will be seen that the leaf 5 may be secured to a door 26 that is somewhat thicker than the casing 27, owing to the fact that the arms 15 are considerably wider than the arms 8 thus providing the abutments or offsets 16. This arrangement eliminates the use of wooden blocks which have heretofore been 11 secured to the casing in order to make same the thickness of the door when using the ordinary hinge with leaves disposed in parallel alignment. Referring to Figs. 2 and 4 of the drawing, I have provided a raising member designated by the numeral 28 and comprising a piece of sheet metal bent in rectangular form. Said memberis adapted to fit flush under the leaf 5 and is provided with screw holes 29 that are arranged to register with the screw holes 13 of said leaf. When said raising member is placed under said leaf and secured to the door 26 by long screws 30 passing through the leaf and raisins member into the door. the device may be used the same as an ordinary hinge in hang ing a door to a casing of the same thickness as the door. 7
The novelty of mv invention resides principally in the use of the raising member 28, the single cylindrical spring container 6. the st ffener flange 2L the shoulders 20 engaging the inner edge of the leaf 5, and the abutments or offsets 16 providing means whereby comparatively thick doors may be hinged to thin casings.
Having thus described my invention. it being understood that minor changes in its construction may be resorted to without departinq from the scope and spirit of the invention, what I claim and desire to secure by Letters Patent of the United States is A spring hinge comprising a pair of leaves each having right anglearms terminatino' in ears, the arms of one leaf being somewhat wider than the arms of the other leaf thereby providing" offset abutments at right angles to said leaf, a stiffener flange having; its ends fixed to said abutments and disposed at right angles to said'leaf, a cylindrical container having its ends fixed to the ears of the leaf having the wider arms and having slots in its end portions, a coiled spring within said container having one of its end portions projecting through one of said-slots and bearing against the leaf having the narrow arms the other end portion of the spring projecting through the other slot of the cylinder, bearing against thestiffener flange, and its end abutting against the leaf with the Wide arms, the inner edge of the leaf having the narrow arms forming a longitudinal shoulder, and shoulders formed on the offset abutments of the wider arms and arranged to engage the longitudinal inner edge shoulder of the other leaf whereby the two leaves are normally held in parallel relation.
In testimony whereof I aflix my signature.
JOHN O. OLSON.
