UNITED STATES PATENToFFicE- ALFRED E. TI'iUs, 0E TRENTON, NEW JERSEY.
Application led October G, 1924. Serial N-o. 741,985.
To all whom t may coacem:
Be it known that I, ALFRED E.'
siding at Trenton, in the county of Mercer and State lof New Jersey, have.` invented certain new and useful Improvements in Door Hinges, of which the following is a specification.
TheA object of my invention is to provide a spring hinge for doors, more especially, the doors of refrigerators. Such hinge to be of a simple, practical and eiiicient construction that will insure the door being Vclosed automatically with a tight joint in its frame; and with these and other objects in view, my invention consists of the partsA and combination paits, as will be hereinafter, more fullylset forth.
In the drawings:
Figure l is a front' elevation of a fragmentary-part of a refrigerator and its door with my improved hinge thereon. Y
Figure 2l is a sectional view of the line 2 2 Figure 1 looking in the direction ofthe arrows. Y
Figure 3 is an enlarged detailed view. Figure i is an enlarged perspective view. Figure, 5 is a sectional view on the line f 5-5 Figure 2.
The reference numeral 1 designates the refrigerator and the door thereof, of any approved construction. i
The long leaf 3 of the hingeis secured to the door while the short leaf 4: is secured` to the refrigerator, as shown inthe drawings. I secured a bracket 5 to the hinge leaf i bymeans of bolts 6,- said bracket having its outer end yoked as at 7. To the leaf hinge 3 I secured a bracket 8, 'having the base plate 9, by means of the bolts 10, the bracket being, as shown in Figure 2, at right angles to base plate 9. I/Vhile' I have shown these brackets 5 and 8 as being screwed to the leaves ofthe hinge by means o f bolts it will, of course, be understood that these brackets maybe cast integral with the hinge. In applying my invention to hinges already on the doors of refrigerators it, Kof course, is necessary that the brackets 5 and 8 be secured thereto by means of bolts, or rivets.'
The bracket 8 is provided with a circular opening, to be hereinafter referred to, from one edge of which extends a circular flange 11 forming with the walls of the circular opening an extended bearing to be hereinafter referred to.
TrrUs, a citizen of the United States of America, re-
Slots 12, diametricallyopposite each "other, forms through the bracket 8, to be hereinafter referred to.
A- rod 13-is pivoted at 14 in the yoke Vend 7. of the bracket 5 and extends through the circular opening 11 of the bracket8,"as shown in Figure 2, said :rod having at one ,end an` adjusted nut 15 vadapted to be adjusted on the screw threads onone end-.of the rod 13, as shown in Figure 2. A stop `16 is rigidly secured on the rod 13 near its' free end and is providedv with arms 17 which are screw threaded into' stop 16, as clearly A coil spring 18 is secured around the rod y13 between the stop' shown in Figure 3.
16 and the adjusting nut 15 and is held between these two members under compression byreason of the fact that the arms 17 are'v prevented from passing through the slots 12 by the ievoluble plate 19 against 4which they bear. This revoluble plate '19 `isxprovided with elongated arcuated. slots 2O in which set screws 21 are mounted, said. set screws passes through both sets of slots thereby relieving the compression of spring 18, whereby the door 2will remain in any position in y which it may be set.`-Whilethe parts are in the position "shown f in VFigui-e 2, tine springA is under compression and the door will a1- ways be automatically forced by set springY to closed position.
After the desired compression has been.
placed on spring 18 the nut 15 is locked lagainst movement by means of set screw 25. In order to cover the rod and spring to 'prevent the lodgment and accumulation of dust, etc., 'I cover them bymeans of the tube 26.
In view of the above description, it is'iiot believed that a detailed statement ofv the operation of the several parts is necessary.
As above pointed out my invention may be applied to existing hinges by simply bolting the brackets 5 andA 8 to such hinges and `mounting the other parts thereon. So in order to availoneself of my invention it is not necessary to throw away the already unsupplied hinge. v
I prefer to provide therhinge proper with antlfrietlon washers 27.
l/Vlnle I am aware that some changes may vbe made in the details ot construction and relative arrangement of parts without departing from the scope of the appended claims,
Vhat I claim is: l. In a hinge, the combination with a bracket secured to each lea of the hinge, a rod` pivotally secured at one end to one of .said brackets and slidably mounted at its yother end in the other of said brackets, a
stop slidably mounted on said rod and adapted toengage one of said brackets, a .spring on said rod, one end or which abuts said stop, a tension slide on theother end of said f" rod against which the other end of the spring abuts. A slot in one of said brackets, and means to move said stop to register with said slot wherebythe stop ma7 move beyond its bracket and release the compression on the spring. f
2. In a hinge of the character described, a bracket for use therewith having an opening therethrough and slots in the walls of said opening diametrically opposite each other, a plate revolubly mounted on said Abracket and having a central opening therethrough the walll of which opening having diametrically opposite slots yspaced equally with the slots in the bracket. Y
S. In a hinge, the combination with a bracket mounted on each leaf ot the hinge,
a rod pivotally secured to one of said brack mit the stop to move beyond the bracket and release the compression of the spring.
4t. In a hinge, the combination with a bracket mounted on each leaf of thev hinge, a rod pivotally secured to one of said brackets and at its other end slidably mounted in the other of said brackets, an adjustable tension nut mounted on the pivoted end portion 0I' the rod, a stop lixedly secured to the other end portion of the rod, a coiled spring on said rod under compression between said nut and stop, a plate revolubly mounted on said bracket-and stop, said bracket and plate having equally spaced and diametrically opposite slots which slots when in register permit the stop to move beyond the bracket and release the compression of the spring and a casing for the rod spring nut and stop,
5. In a hinge, the combination with a bracket on each leaf of the hinge, a rod pivotally secured to the bracket on one of said leaves, and slidably mounted at its other end in the bracket of the other leaf, a coiled spring on said rod, diametrically opposite slots in the walls of the opening of the bracket with which the rod has a sliding relation, a stop adjustably ned on said rod and dian'ietrically opposite arms extending at right angles from said stop, and adapted to pass through the said slots, a plate revolubly mounted on the bracket with which the rod has .a sliding relation and provided with an opening registering with the opening in the bracket, diamet-rically opposite slots in the walls of the opening in said plate and adapted to register with the slots in the opening of the bracket to permit the stop and its arms to passvthrough the openings in the bracket and revoluble plate, to release the tension on the spring, and a tension device on said rod to govern the tension'on said spring.v Y s A In testimony whereof I affix my signature.
