Appiicnon inea May i2,

To all 1li/1,0m z'z 'may concern Be it lrnown that I, FVILL'JAM L. EvansV Jr., a citizen'of the United Sta-tes, residing at YWashington, in the county of Daviess and State of Indiana, have invented new and useful Improvements in Hinges, of which the following is a specification.

This invention relates to hinges of the multiple pivot type, in which a door: plate and a. pair, of floor or ceiling plates are combined with a pair of swinging arms, the op- Y posite ends of which are pivoted respectively to'said plates in such relation to each other that they will always assume a non-parallel r position.V

TheY present invention is anV improvement on the hinges shown, described and claimed in my prior Patents No. 1,367,954 and No. 1,407,790, dated respectively February 8th, 1921, and February 28th, 1922.

In the hinge of the first patent, the elements of the hinge are not permanently connected together at the factory, but are constructed so as to be shipped in knoclndown .form and assembled on the job. When applying the hinges tothe door, it is necessary to properly space the arms, and this requires considerable care'and experience' in o-rderV that when the hinge is fastened to the door, the terminals of the arms will stand vertif cal; otherwise when swinging the arms they would bind and make the door hard to operate even to the extent of loosening the plates which have been seouredto the door.V Moreover, in this construction, wherein hinges are located at the top and bottom, theV load is entirely carried by the arms of 'the bottom hinge and this, to a certain extent, limits the application of the vhinge to lightv structures.

In the later Patent.1,407.790g-certain of the defects of the hinge of the first-mentioned patent'were avoided 'by making the hinge in entirely assembled form at Vthe factory; and also constructing the hinge so that the load should be divided between the top and bottom hinges of the door.

The extensive manufacture and sale ofV Vthese hinges has made it necessary to develop a further improvement` which is presented by the'stiucture ofthe present application, consisting of an improved connection between the terminalsof the arms'and the door and ceiling plates, and also by constructing the door plate of agi-eater length than the vlength of the arms, this construction being 1923. Serial'NoqGBSSG.

of advantage notonly in shipping the completed hinge, Ybut-.when Yapplying the Vhinge in position.

Also by this construction, ahinge isV prof from the bottom hinge; moreover the parts of thehinge are permanently Vconnected and assembled precluding the loss ormisplacement of any of the parts; and finally the hinge is'much easier to install on the door, and can be putin place by skilled person, for when the door plate is placed. horizontally onthe door, the termi- Y nals of the arms automatically assume avertical position in properV relation with the door. Y i

The invention will be best` understood `from aconsideration of the following de-l tailed description, taken in connection with Y the accompanying drawings forming partY of -this speciiication, with the understanding that the invention is notV limited to a. partic-V ular or exact form as'representedv in the drawing, but may be changed andmodified so long assuchvchanges and modifications features of the invention, appended claims. y

- r or other moyaole member is proh an ripper hinge and' a lower hinge7 each hinge consisting oi a pair ot arms, a door plate, and a iair oit "floor or ceiling plates. is the uL f and loi-yer hinges differ from each o only in the lenoth of the terminals oi the sii'ingingv ai. s, it is deemed unnecessary to describe both hinges. as a desorption ot one hing l apply to the other. a ach hinge has a pair o'i sir' l. l0 and ll ot' al'iproxiinately the sci-me fenff' and they are constructed like the arms a Each arm has an nptnrned and don'ntnrne-:l teri nal marked The nnturned terminals i0?? i it the lon'er hinge are lons .r than the do ed terminals l0", lib of the arms oi? the same inge While they terminal s the np# the corresponding Yterminals of the a oi the loiyer hinge.

The door plate l2 is made oi 'fiat metal and is secure to the inner ace or Jhe door hy screws or bolts at a oiit between the opposite side enges. The opposite ends of the plate are notched or cut ont a point hetiyeenthe top and bottom` and the metal aboye and below each oi the notches is coiled 'nto knuckles 122 which are yertically alined and spaced J530m each other by the said notches. Mounte in each notch or ch tasten-ed to the nptnrned terminals lilla. lla.. by a riyet or by spot-Welding'. By this construction, the collars turn with the uptnrned ences of the armse which in turn moye in the knuckles as the arms are sirene1 to and iro.

The downtnrned ends 10b and ll of tlie arms are secured to the Vdoor plates l2 in the manner shown in Figs. 3., ll. 5 and (i of the drawings. The iloor nietes are iorniediyith centrally disposed bosses provided with openings to pass the doWntiirne-d ends oi the arms, and are connterbored to form a recess or pocket to receive a collar lil. which is riveted or spot-Welded to the extremity of the terminal. i

Above the door plate. is another collar l5, ch is riveted or Spot-Welded to the termi-y nal. By this constructionl the two collars are caused to .more with thc terminal oi the erin. the collar l/l turning Within the recess o? the 'door plate. `while the collar lc,- turns on the outside ci the boss oi' the lio-or nlate. the tWo collars supporting` the load lcarried Y by the arms.

In applying the hinges to doors, the door oositionr and secured temporarily. The door plate should be placed horizontally on'the door, with the end of the plate about nine inches from the edge of the door, assuming that the arms are seven inches long, the iioor or ceilinp; plates just touching the lioor or ceiling, as the cese may he, and the door plate then secured i this position. NextV shi't the floor and o' plates alone` the floor or ceilingso i n eine' through the center .ch plate sh extend at a right angle ie door opening3 and screw the plates .esiti-ion. llepeat this the top for t 'ipper hinge and the door will be properl "tanl feature of this hinge is the door plate which exceeds the ther oit the arms. This is necesa. J- v L ce;V to atoid clashingy betr.. een the cn in this construction, Work in orizontal plane.

s terrine to Figure 2 of the drawingse wherein the door or moyable member is shown in a closed as Well as an open position, and the movement from the closed to the open position is indicated in dotted lines, it vwill be noted that the floor plates are locate in a straight line at different disiiroin the opening or Ventrance to the onipartnieirtyn and that said line yis at right Ns to said entrance or opening or to the door when closingJ the latter.

.it will also loe noted that in the closed poi sition of the door, one of the arms is at a sli 2eht angle to the door, While the other1 arm is at an a" le greater than a right angle and tiet the aries in their progressive movement heifer assume a parallel position to Veach swing in the saine horizontal plane. When the door is swung to its completely open nosition, the two arms are at an angle to each other. and thus hold the'door firmly in its open position Without the use of any tastenine: means.

By reason of the mounting of the ends of the arms in the floor door plate and floor and ceiling plates.A each arm carries its share of the load. and this arrangement enables the of the upper hinge toassist the arms of the lower hinge in sustaining the Weight of the door.

rl`he hinee of the present invention is capable oi' all the uses of the hinges of the aioresaid patents. being adapted to be applied to the doors of closets, screen partitions, wardrobes. garages, coal chutes. or to the sasl-,ies oi Windows. ventilators or to any movable part or member which is designed to close either a compartment* space or room, Where it is desired that the movable member shall vanish Within the compartment When open. The hinges are all made alike and are capable of being applied for either right hand or left hand use.
