Patented Apr. 7, 1931 NORTON A. MEARS, OF CHICAGO, ILLINOIS ,assmma To c FACTURING COMPANY, or CHICAGO, IL-L'Irmrs, n oonPoRATion or iLiL'I'NoIs HINGE Application filed December My invention relates to a hinge and par ticularly to a hinge which may be used to support two or more adj acently hinged members. One use of my invent-ion is for the hinging of adjacent and overlying cover members. Another object is to provide a hinge in which covers or hinged members may be raised separately or together. An-

other object is to provide a hinge of the general type disclosed in which all the parts are made of stampings or :E-orgings and in which castings are eliminated. Other objects will appear from time to time in the course of the specification and claims.

I illustrate my invention more or less diagrammatically in the accompanying drawings, wherein Figure 1 is a side elevation of my hinge with parts in section;

Figure 2 is a rear view of the hinge with parts broken away; and

Figure 3 is a section on the line 33 of Figure 1.

I Like parts are indicated by like symbols throughout the specification and drawings.

A generally indicates any suitable base or abutment upon which the hinge may be employed. A is a hinge base member provided with .a square or non-circular aperture A adapted for example to receive the squared portion A of the buttonhead bolt A The shank A of the bolt passes through a circu lar aperture A in the base A and when the bolt is drawn into'position, as by the nut A the hinge base member A is not only firmly held against the base A, but is held against rotation about a vertical axis. The base A is provided at one end, with the upwardly turned ears or lugs A having the aligned apertures A I p B indicates a pivot pin passing through the apertures A. It may forexample be headed as at B with the opposite end upset as at B although-I do not wish to limit myself to any particular means for or method of holding the pin in place. Mounted for rotation about the pivot B are the hinge members B and B The member B is indicated as relatively short and as having cars 13 which are curled to form the apertures B through which passes :thepin B- -Note that theears B are positioned exteriorly of the lugsor "e'a'rS A of the hinge 'base'A The hinge member B is provided with a a single "ear which is curle-d'to form-an eyelet B through When'thehingebasememberA or apair i i of them, when a pair areemployed, ar' placed upon; the 5 base A, they maybe secureda and positronedg-j as='by-'- dropping the carriagebolt l "or buttonhe'ad bolt A A A into the'f posif- 'tion; in which it te -showman 7 Figure; '1.

On the other hand they may both be rotated simulioeeo renam emiw p taneously. No matter whether they are rota-ted simultaneously or not their relation is always the same at the end of the movement of rotation of the two covers.

An additional advantage in my device rests I in the fact that it reduces to a minimum the exposed members and tends to give a concealed hinge effect. In doing away with the heavy castings and cross-bar of the present conventional hinge employed for example in toilet seats, I. reduce the exposed surface and limit the accumulation of dirt thereon and corrosion thereof. The entire device, the base a and the hinge leaves, including the hinge, is more readily cleaned and kept clean.

I claim:

1. In a hinge for a multiple hinge member, a hinge base and means for securing it and for preventing its rotation about the axis of the securing means, a pivot receiving upward extension from said base, and a plurality of hinge members concentrically pivoted to said extension, said extension including a pair of cars or lugs and a pivot pin extending through said ears, one of said hinge members being provided with bearing portions in engagement with said pin outside of said ears, the other being provided with a bearing portion engaging said pin between said ears.

2. In a hinge and cover assembly, a base member, a plurality of hinge members conentrically mounted thereupon, said hinge members being of unequal length and being adapted to lie, when at either limit of their rotation, in closely adjacent parallel planes, a lower cover member fixed to the shorter of "aidhinge members and an upper cover member fixed to the longer of said hinge members.

3. In a hinge and cover assembly, a base member, a hinge abutment projecting upwardly therefrom, a plurality of hinged mem bers concentrically mounted upon said hinge abutment, said hinge members being of unequal length, a lower cover member fixed to the shorter ofsaid hinge members and an upper cover member fixed to the longer of said hinge members, said hinge members lying in planes generally perpendicular to the planes of said cover members.

4. In a hinge, a base member, a pivot abutment projecting upwardly therefrom, a plurality of hinge elements concentrically pivoted thereupon, said hinge elements being of unequal length and being adapted, at either limit of their rotation, to lie in closely adjacent parallel planes with the opposed faces of the two hinge members in contact with each other.

Signed at Chicago, county of Cook, and State of Illinois, this 21st day of November,

NORTON A. MEARS.
