Specification of Letters Patent.
Continuation of application Serial No. 173,358, filed June 7, 1917. This application filed November 15,
' 1917. Serial No. 202,204.
To all whom it may concern:
Be it known that I, WILLIAM L. EVANS, J12, a citizen of the United States, residing at Washington, in the county of Daviess and State oflndiana, have invented a new and useful Multiple-Lever Hinge, of which the following is a specification.
The invention relates to a hinge, and more especially to the class of vanishing. door hinges of the multiple pivot lever type, adaptable for use with wardrobes, telephone booths, lockers, lavatories, cupboards, cabinets, cases, garages, exterior and interior doors for public buildings and residences, steam or street railway cars or the like, their use being unlimited. The subject matter of this application is a continuation of an application filed on or about the 7th day of June, 1917, Serial Number 173,358.
Theprimary object of the invention isthe provision of a hinge of this character wherein single or double doors may be mounted to open and close, either to the rightor left, and when opened vanish within the compartment, booth, etc., thereby minimizing floor space, and avoiding obstructing the aisles or blocking the entrance to the adjoining compartment or booth.
' Another obj ect of the invention is the provision of a hinge of this character, wherein the movable member, such as a door, cannot stick; may be easily opened and closed; will operate without noise, and will not sag.
A still further object of the invention is the provision of a hinge of this character which is extremely simple and strong in construction, durable in use andinexpensive to manufacture and install.
The invention will be best understood from a consideration of the following detailed description, taken in connection with the accompanying drawings forming part of this specification, with the further understanding that while the drawings show a practical fornn and the preferred embodiment of the invention, the latter is not confined to any strict conformity with the showing of the drawings, but may be changed and modified, so long as such changes and modifications come within the scope of the appended claims.
In the accompanying drawings: I

Fig; 10 is a diagrammatic view showing by heavy and dotted lines, the paths oi travel of the door and hinge arms or ele-.
ments. respectively, in the opening and closing of the door.
Referring to the drawings in detail, particularly Figs. 1 and 2 thereot,"-A designates generally a telephone booth. of the wellknown construction. having therein a series of compartments B as usual, with an entrance. on opposite sides of which are jamb strips 11 serving as stops for the swinging door 12 when closed. The booth A in this instance, is made up in separable units. each comprising a floor 13', outer side walls 14,
back or rear wall 15, and a top 16 which are connected or joined together in any suitable manner, while the front of said booth is entirely open.
Each door 12 is mounted for movement upon hinges comprising upper and lower pairs of arms or elements C which, as shown, are in the form of double cranks (see Figs. 7 8 and 9 of the drawings), though I desire Patented Feb. 8, 1921.
it understood that this is merely the preferred form of the invention, and that it is susceptible of wide variation. Each arm or element includes a main straight portion 21 and vertically disposed oppositely extending terminal pivot ends 22 and 23, re-i spectively. The door has fixed thereto sleeves or socket bearings 24 formed with base plates 25 (see Fig. 6), having suitable holes for fasteners;to secure the bearings upon the door at its inner side, and provided with closed ends 26 to limit the insertion of the pivot ends 22 in the sockets. The other ivot end 23Iis engaged in a base or top bearing 27 referably formedwith a disklike base (see Fig. 5), and a socket 28 which rotat-ably receives said end 23 therein when the door is hung on the hinges.
The arms or elements C are-pivoted by means of the door bearings 24: to said door 12 on opposite sides of its longitudinal center but nearer to said center than to the side edges of the door, one pair of the arms or,
' extending horizontally from the front to the back of the compartment, which line is substantially parallel with the door when the latter is open, the space between said base and top bearings being shown as less than the space between the'door bearings. This imaglnary straight line is substantially at right angles to the opening which forms the entrance-to the compartment. By this arrangement of the arms or elements, the latter do not assume a parallel position with respect to each other, and each arm or element describes a different are from its fixed center of rotation. This will be made clear upon an examination of Figs. 2, 4 and 10 of the drawings.
at 0) just before the door reaches its open'.
position. The curved heavy line-e indicates the path followed by the central longitudinal axis of the door, "and theheavy line 7 shows the path of movement of the inner edge of the door. This diagram shows that the outer arm or element moves a half revolution and the inner arm or element a quarter revolution in opening and closing the door, and it position does not swing laterally towardthe' center of the booth, and that what lateral movement it has is practically all toward the side of the booth. The result of this is that the size of the booth or compartment may be reduced to the minimum, as allow.- ance does not have to be made for the move,- ment of the door; and moreover, the latter in moving cannot contact with any furniture Within the booth or compartment.
VYhen the door is in its closed pos1t1on,the outer arm or element is about parallel with the door, while the inner arm or element stands out from the door at an angle less than 90 to the door. As the door begins to open, it turns on the outer pivot 22 of the inner arm or element, (the arm or element itself moving very slightly), and swings on the'inner pivot 23 of the oute r arm or element, the latter remaining at this time practically parallel with the door. As the door continues its outward opening movement, the inner arm or element moves very slightly as before, while the outer arm or element not only swings on its inner pivot 23, but turns on the outer pivot 22, this operation continuing for a distance of approximately 45 to 60 of the opening-movement of the door. element begins to move more perceptibly and with increasing speed on its two pivots,
the outer arm or element moving more rapidly, and both arms or elements turning on both pivots. After the outer arm or element has completed half of its movement, the two arms or elements practically move together, the inner arm or element continuing to increase its speed, and both arms or elements turning on both theirv pivots, until finally the armsor elements assume the position shown in Fig. 7 of the drawing, with the door completely open.
In closing the door, the reverse movements take place; that is to say, the two arms or elements turn on both their pivots and move practically at the same speed, the inner arm or element slowing up but slightly until the outer arm or element approaches one-half its movement, whereupon the inner arm or element slows up more perceptibly until its motion is hardly noticeable, with the outer pivot 22 of the inner arm or element contiguous to the inner pivot 23 of the outer arm or element, the outer arm or elefinally; closed, when the two arms or elements assume the position shown in Fig. 9.
It will be noted that when the door is open, the two arms or elements are not parallel with each other, and when the door is From that point, the inner arm or.
ment continuing to turn until the door is closed the outer arm or element is substantially parallel with the door, but the inner arm or element extends out at an angle less than 90 to the outer arm or element.
When the two arms or elements are made of equal length as shown, they never assume a position parallel to each other at any time in the opening and closing movements of the door.
The door 12 in its movements when swung to open and closing positions, has the major portion thereof traveling within the booth or compartment, so as not to project the door to a material extent outside of the booth, thereby reducing the amount of floor space required in the operation of said door.
011 completely opening the door 12, it is well within the compartment B close against one of the side walls, while the outer edge of the door slightly protrudes beyond the entrance or door opening, thus giving a wide and unobstructed range of access to the compartment in the series of units thereof, and
avoiding encroaching upon the adjoining booth or compartment. I
The arms or elements C are shown as of equal length in each pair, and this is the simplest and preferred construction, yet the length thereof may be varied, as the occasion v 31 are constructed identically like the arms or elements C, and are mounted in bearings 32 and 33, respectively, carried by each door and on the floor and ceiling of the locker, said bearings being similar to the bearings hereinbefore described.
