Application tiled Gctober 8,

To all eas/1.0m it may conce/m.' f

Be it known that "I, AUGUsr SUNDH, a citizen of the United States, residing in Hastings-uponludson, in the county of estchester and State of `rlew York, have invented a new and useful Improvement in Hinge Mechanisms, of which the following is a specification.

My invention relates to hinges for use on doors, gates, and the like, and is particularly adapted for usein situations exposed to the weather, and where they receive no particular care. It is a matter of common knowledge that outdoor hinges or hinged gates seldomvworlr perfectly. This isvdue largely to ineliicient lubrication, and because the hinges.` springs, and other kmechanism are subjected to the elements and rust and wear rapidly, and also becomecl'ogged up with mud, ice, etc.

An object of my invention is to overcomer these objections, and provider an automatic self-closing gate having 'zi-hinge inclosed vin a casi-ng which forms an oil reservoir so constructed 'as `to prevent rust, or `the access of water, dirt, ice, or any-thing to interfere with the perfect working yof the' mechanism.

Other objects `of the invention and the exact nature thereof will appear hereinafter.

Referring Ito the accompanying drawings, Figure 1 is a sectional elevation y view of hinge mechanism constructed in accordance with my invention, and also showing a portion of a gate attached thereto ;4 Fig. 2 is a sectional 'elevation view ,of the hinge mechanism taken on a plane at righty angles to that of Fig. 1; 3 is a'sectional view as`indi' cated by the line 3-3 'on Fig. Q; Fig. eis sectional view as indicated by the line on Fig. 1; Fig; 5 is a view showing a gate with my -improved form of hingeattached thereto;` Fig. '6 `is a similar view showing a modified arrangement for attaching the gate to ,its support. o A

The gate G, as shown in Fig. 5, is hinged to a gate post 1 by means of the hinge mechanism A, 4nmunted 'on the upper end of the post l `and lower hinge 2; fthe latter is in the' form of astrap or heavy band loose on the postand riveted or otherwise secured to the gate. This arrangement permits the gate to move up and `down freely, as herein set forth; A dummy A', corresponding in outward appearance to the device A; may be mounted on the opposite gate post.

tail. infigs. 1 and 2, comprises a stationary member 3, the upper portion of which is in the 'form of a cylindrical receptacley 11. De pending `l'rom this receptacle is an extension 5 adapted to enter the hollow post 1. Ribs 6v formed on the extension o,have a tight t in the postand secure the member 3 rigidly in positioi'i. These ribs may be of sullicient depth to slightly spring the postl vtr-hen driven into place. Extending upward within. the receptacle is a tubular projection or sleeve 7. `The opening through the exten.- sion 7 is continued downward into the 'projection 5J as shown, and forms a cylinder or k'socket to receive a vertical pivot pin or pintle 8. This' construction provides a long vertical .bearing surface between the hinge members, which reduces wear to a minimum and 4prevents the-gate from sagging.' Rigidly secured to the pintley S is a movable hingey member 9. The latter is in the form of a hollow cylinder or sleeve with a portion cut away vto form inclined bearing surfaces 10. The latter cooperate with an anti-friction roller 11 mounted for rotation on a pin 12; Said pin is threaded into the wallof the `oil chamber or receptacle e, and also has a bearing in the extension 7. The roller 11 is frustoconical in shape so as to present an inclined bearing surface, `on which the inclined surfaces 10 of the movable hinge member are adapted to roll. 10 are substantially spiral or helical, so that the pitch is uniform throughout. Mounted on the hinge member 9 is a protective device 13 forming a cap or cover for the receptacle e, an'dffparts contained therein. An outer flange `1i 'extends downward outside of the oil chamber e, and an inner annular flange 15 entends downward` within the oil chamber. Theliange' 15 forms a squared opening 16 with its sides vflaring outwardly and downwardly to receive the upper squared end `1'? of the rotary hinge member. lt will be observed that the coperating 4surfaces of the `

darts

15 and 17 are somewhat diverent to permit a limited swinging movement of the member 13 in the plane 0f the gate to accenimodate'the .latter if the hinges are not in exact vertical alinement. rl`his Aadjust#r The surfaces ment is preferably permittedonly in one `dif rection;` the bearing surfaces at right angles being preferably a close-ht, as indicated in Figft: with an extensionA I2() forming a socket to receive a `v"section 21 -of the fence.' The -oil The member -3 be provided casing is adapted to contain a suitable lubri eating oil which when the member 9 is in its lowered position completely covers the bearing surfaces l0 and 11. T he pintle 8, which forms a pivot member is adapted to rotate freely and also to have a vertical movement in the cylindrical opening through the parts 5 and 7. rhe groove or recess 22 extends from the lower end of said rod upward to a point beyond the upper end of the/projection 7. T he purpose of this groove is to permit the escape of oil fromthe lower end of the cylinder as the rod descends, and to permit the entranceof oil as the rod is lifted. Said opening` may be of such size as to throttle the fluid more or less as the gate'swings to a closed position, and thereby effect a dashpot action, preventing too great an acceleration of the gate as it swings by gravity to its closed position. A bracket 24 preferably cast integral with the 'cover member 13 forms a rigid'connection between the latter and the gate.

The operation of my improved hinge mechanism will be apparent without any extended explanation. As the gate is swung open in either direction, the hinge member 9 is compelled to rotate with the gate and the inclined surface l0 rides up the roller 11, thereby lifting the gate in a vertical direction through a distance proportional to its swinging movement. When the gate is released its weight carries it downward andV the inclined bearing surface 10 causes it to swing to closed position, where itl is automatically fastened by a latch device 23. The latter is preferably constructed in accordance with my invention as fully set forth in my co-pending application for patent on latch, filed of even date herewith. As shown in Fig. l the gate and moving parts carried thereby swing about a vertical axis extending through the center of thepost 1.

In the arrangement shown in Fig. 6 the hinge devices A are provided both at the top and near the bottom of the gate. In this instance the brackets 25 are used to attach the hinges to the gate post. Y

As the hinge mechanism is fully inclosed and the relatively movable contacting surfaces arekept in an oil bath and continually lubricated, a smooth, reliable and eflicient action of the mechanism is insured. The parts are fully protected against they entrance of dirt, ice, snow or vforeign substances of any kind. They are also fully protected against rust. The mechanism therefore does not quickly get out of order as do the usual constructions in use at the Vpresent time.

f giving entire satisfaction. It will be understood that various modifications in the details-ofconstruction and arrangement ofr parts might be made without departing from the spirit and scope of my invention. I wish therefore not to be limited to the precise structures herein disclosed, as the invention comprehends all such modifications Aas come within the scope of the appended claims. y
