Specification of Letters Patent. Patented Feb. 28, 1922 imputation aiea'rebruary 24, 192i. semaine. 447,417. I

T0 all 107mm t may concer/11,:

Ber it known that l. lll'iLLniM L. Evans,

Jr., a citizen of the UnitedStates, residing'y at 'Vashington, in the county of Daviess and State of Indiana, have invented `a new and useful Hinge, of whiclrthe following a specification.

This -invention relateslto hinges of the multiple pivot type, in which are combined with a j amb plate and a door plate, a `pair of arms, the opposite ends 4of which are 'pivoted, respectively, to the said plates in suclirelation to each other` that they always assume a non-parallel position.

The invention is generally an improvenient upon the hinge showindesc 'ibed and claimed 'in my Patent, No. 1,367,954, dated February 8, 192i, but is more specifically an improvement on the construction of hinge shown, described and claimed in my cepending application, Serial No. 3&G,45'5,iiled Dec.

In said application, l have shown the jainb plate made angular in form, having at opposite ends vertical holes or sockets, which, when the jamb plate isapplied to the door jamb, disposes the said holes orsockets respectively inside and outside `the entrance or opening closed by the door, in different vertical planes. Associated with the angular jamb plate, is a door plate rigidly mounted on the door, and also having a pair of holes or sockets. The holes or sockets in the amb plate and door plate are adapted to loosely receive, respectively, the downturiied `and i'ipturned ends of a pair of swinging arms, said arms being removable from the jarnb plate and door plate at will.l v

In said construction, considerable mechanical skill is necessary in properly mounting the door and jamb plates in order to receive the ends of the swinging arms, and cause themto properly function, and, moreover, there are certain limitations imposed on suoli construction which prevent it from being used for general purposes.

To construct a hinge which is more easily k.installed and adapted` to a wider range of usefulness, I have connected the jainb plate and Vthe door plate to theends of the swinging arms, so that the four elements constitute a single unitary structure. I have made the arms out of two plates of flat metal, and have formed the pivotal connections between the arms and the door and jamb plates of interlockiiig eyes of articulated construction connected by hinge pins or bolts, the structure resembling` the ordinary butt hinge of commerce, but possess-' v ing advantages and having uses which are incapable of being performed byv ordinary hinges.

This new construction of hinge lends itself for use as an overhead hinge in warehouses, factories and garages,l in which uses, when the door is raised to its open position, it is adapted to form an awning or protection for the opening. It is, however, useful for ex@ terior and communicating doors,` garage doors, telephone booths, wardrobe lockers and even on many kindsof furniture.

The invention will be best understood from a consideration of the following detailed description, taken inconnectionwith the accompanying drawings' forming part of thisv specification, with the further understanding I.

that while" the ydrawings yshow a practical form oli' the invention, vthe latter is not con-V fined to strict conformity with the showing of the drawings, but may be changed and modified so longas such changes and modifications come 4within the scope of the appended claims. i i

Like reference characters indicate corresponding' parts in the several figures of the drawing.

The hinge constituting the present 4invention is represented in detail in Figs. 9 to le, inclusive, of the drawing. y

It consists in part of two arms 10 and 11 made of flat metal of the same length, width and thickness. `F or general purposes, they are each made eight inches long, but the length is varied to suit the special conditions of service. Both ends of the arms arev provided with spaced square notches, and the material is bent between'thenotches to form pintle eyes. In forming the eyes, the material is bent inwardly only so that the eyes do not project beyond the outer face of the arms (see Fig. 1l). By making the arms identical in shape and size, they may be stamped from the same dies.

The hinge includes a door plate and a jamb plate pivotally connected to the two arms. Both plates have substantially the same width as the arms. Thevdoor plate 12 is alsomade of Hat metal,-and is formed at its opposite ends with pintle eyes separated by notches in the same manner as the armsv l0, 11 and is providedwith screwiholes for the reception of screws or bolts in fastening,

the door plate to the-face of the door. The j amb plate 13 is bent transversely at an intermediate point of its length and` thereby made angular in form, and is providedV with holes tor screws or bolts in fastening the sameon the j amb, and has its ends provided with pintle eyes separated by notches the same as the door plate and the twoarms l0, 11. The jamb plate is larger than the door plate.. l

In assembling the parts of the hinge, the

pintle eyes onthe arms 10 and 11 fit in the Y notches which space'the pintle eyes Vof the door and jamb plates while the pintle eyes of the said plates ht in the notches oi said arms, in this way forming what is known as an articulated joint. being substantially identical in principle ot construction to the ordinary buttshinge. After the pintle eyes are thus assembled in matching relation, then pins or bolts are passed through the alined eyes so as to connect the four parts of the hinge together; that 'is to say,`the arms 10 and 11 each have one end connected in the manner described to the opposite ends of the door plate, while the other` ends ot said arms are connected to opposite ends of the jamb plate. In practice, the pins or bolts 14, which connect one of the ends of the arms 10 and 1]A to the door plate, and the pin orbolt 15 joining the other end of arm 11v to the jamb plate, have their ends riveted so that they cannot become detached,

but the pin or bolt 15EL connecting arm l() to the end ofl the j amb plate is maderemovable for the purpose of permitting the hinge to be mounted in place. It will be obvious that by removing the bolt 15a, the j amb plate may be detached at one end and the arms of the hinge .opened out allowing the door plate 12 to `be fastened to the door, at'tcr which the jamb plate may be-fastened in place, and when this is done, arm 10 may be again connected to the free end of the jamb plate and held thereto by the 'boltl 4 The hinge may be applied to a door swinging in a horizontal plane or. in a vertical plane, and I have disclosed herein both uses of the hinge. In vmaking either application, the only change necessary in a standard door frame, is thata strip 16 be sccured to the door frame to which the hingeV is secured.v This strip, which should be of substantial construction, is grooved out at 16L to receive one arm of the j amb plate. (See Figs. 6 and 15). The other arm fits against the outer exposed face of the strip, andboth arms are secured in place by screws or bolts', as shown. This arrangement brings the pivotal connections of the arms 10 and 11 to the jamb` platefin different vertical planes, and at an angle to each other,the pivot, connecting the arm 10 to the jamb plate being located at the inner endof the groove 16a, and inthe angle formed between fiatv said strip 16 and a part of the doonframe.

The other connection between the arm 11 and the jamb strip is extended out beyond the strip 16 and is spaced therefrom. Prccisely the same arrangement is followed, whether the door be hung toswing vertically or horizontally, as will be obvious upon a comparison between Fig. 6 and Fig. 8, the

latter representing the mounting yof the hinge when the door swingshorizontally.

Fig. 7 shows the improved hingemounted l on an ordinary ldoor 'swinging in a horizon-v tal plane, it being noted that the hinges are applied directly to the face of the door. In small doors, two hinges are all that are necessary, each composed of the `elements shown inv Fig. 9; but in large doors, three or even four hinges may be found desirable for use,

and they may be made of greater dimen-k sions than the size previously given.

In F l to 5, inclusive, the hinge is shown in connection with doors which are swung upwardly. three doors are sliowmeach equipped with two hinges. closed, and the other swung up into a horizontal position, in which position the door serves as an awning or protection for the opening, which is normally closed by the door. In small doors, no counter-Weight is required to hold the doors in their open horizontal position when once raised, for the reason that the arms of the hinge reach past theghorizontal center .of the door, but in the caseof large doors, it isnecessary to use a Weight to counterbalance the same and' to hold the doors in such position.k I have shown in Figs. 3, 4t and 5 how counterbalancing Weights may be applied. In Fig. a single large Vdoor 1s shown having a conn-v terbalancing Weightconnected byv ropes to the sides of the door, and moving in guides of the framework. This door is shown pro vided With four hinges. Fig. 4 represents a.

sectional view shovvingthe door closed, While door open 1n a horizontal.

Fig. 5 shows the position. g l

It ivill ybe understood that this constructionlof hinge possesses all the advantages of thev hinge structure shown, described and claimed in my co-pending application Serial No. 346,455, but has thefurther advantage.

cially adapted. In churches andgschools, it

is customary to provide movable partitions to dividethe auditorium into separate class rooms. At the end of the class exercises it is necessary to remove the partitions, which takes considerable time and trouble, but with the hinge of the present invention, the partitions may be raised and carried up to the top of the frame in a horizontal plane, Where they are out of theavay and above the headr of any person in the room, andithis may lbe accomplished with little effort.Y and almost` at a moments notice.

Thisfeature isalso desirable for garage doors, for vwhich purpose the door may be made as three separate doors, as shownin Fig. l, or as a single door, shown in F ig. 3.

This constructionis also adapted for Warehousesand factory purposes, in which uses In 'Fig'. l, a `series .of

Tivo of the doors are shown awning for the opening, makes is peculiarly popular.

The construction may also be employed..

for short doors or sashes, or doors under stage fronts for schools. Y

vThe hinge of the present invention may be applied to ordinary lhorizontal swinging.

doors,asfsho\vn in Figs. 7 and 8 of the drawings, all thechange necessary to be made be ing to remove the ordinary hinges and apply the hinge of the present invention by inserting the strip 16 previously described.

The hinge is also useful for exterior and communicating doors, telephone booths,

v1wardrobes, lockers, passenger coach doors,

this in- As hereinbefore stated, the pin or bolt 15 I,

ifonnecting the arm l()` to the'inner end kof the' jamb plate, is the Vonly one ofthe four. pins or boltswvhich is made removable. NOW, when the door is in the closed position (see Fig. 6), it will be noted that the edge'of the door overhangs the piniorbolt, and itl cannot then be removed. yThe pin or bolty can only be removed when the door is eitherl partly or entirely open; Of course, in struc@y r doors or other closures, I do not Wish to be* limited to special applications of the hinge,

for I have already indicated that it hasYV a very WideA range of usefulness. In the claims,` therefore, I shall use the terms stationary member 'and movable mem# berlin referring to the jamb or door frame and the door respectively, for in Whatever relation or position orruse the hinge may be put, one part of the hinge Vmust be seicured to a Vmovablememberand the other part to a stationary-member. s f

The operation of the door* in swinging from a. if'ertical vlto fa; yhorizontal position is shown 1n dotted lines iniFig. 6 of the draw'- ings. The same' operation may be underof the door vanishesk Within the compart- Vment stall, booth or space closed by the door.

The extent to which the door vanishes with# in the compartment, ete.,-may be regulated by increasingor decreasing the length of the arms 1,0, l1.
