RAY B. COX, BERKELEY, CALIFORNIA.

HINGE.

Application filed July 13, 1922.

To all whom it may concern:

Be it known that I, RAY B. Cox, a citizen of the United States, and a resident of Berkeley, in the county of Alameda and State of California, have invented new and useful Improvements in Hinges, of which the following is a specification.

This invention relates in general to hinges, and more particularly to a form of flush hinge adapted to be used for table tops and the like, where it is necessary and desirable that the hingebe positioned either'below or flush with the upper surface of the table. Another object is to provide a flush hinge of selffsupporting character which in addition to performing the functions of a hinge, will also serve to support one member in horizontal alinement with another member, and thus eliminate the necessity for cleats, brackets, or other supports such as are used for table tops and the like.

A further object is to provide in a hinge of the character described, a pair of main hinge noembers similar in form and character to'ordinary strap hinges, which are pivot-ally connected together at their inner ends at spaced points, instead of at a single point as in the case of the ordinary strap hinge. In other words, it is an object to provide a linked connection between the fulcrums of the two straps of the hinge, so that when the said.straps are folded together, their adjacent faces may be in contact. r

Still another object of this invention is to provide a pair of straps, each of which is provided with right-angular abutments for contact with each other, a plurality of links pivotally held on and connecting said straps, and a plurality of depending and abutting members adapted to be fixedly held in the adjacent portions of the members to which the hinge is attached, so that when one of said members is extended relative to the other, the upper surfaces of both members will be flush.

Other objects will appear as the description progresses.

I have shown one practical embodiment of my invention in the accompanying drawings, in which:

Fig. -1 is a plan viewof my improved hinge shown in connection'with a fragment of two table members which are hinged togather thereby.

Serial No. 574,686.

Fig. 2 is -a 22.

Fig. 3 is. an end View of the hinge with one set of the connecting links and abutments omitted.

Fig. 1 is a perspective view of the lower side of the hinge in extended position.

Fig. 5 is a perspective view of one of th hinge straps dis-asssembled.

Fig. 6 is a perspective view of one of the abutments dis-assembled.

Fig. 7 is a perspective view of one of the hinge links dis-assembled.

Fig. 8 is a perspective view of the hinge in folded position.

Fig. 9 is a section of the hinge on line 9-9 of Fig. 1.

Fig. 10 is a section of the same on line 1010 of Fig. 1.

By reference to the said drawings it will be observed that my hinge includes a pair of

straps

1, 1, each of which has elongated

flat members

2, 2, adapted to be secured to opposite members T'and T of a table or the like, by means of screws which may be inserted through a plurality of holes 3, 3, etc., therein. Members T and T of a table shelf or the like are relatively foldable so that, for instance, the member T may be folded backwardly over the upper surface of the member T by means of my hinge. The

members

1, 1, also have depending flat members l, 4, which are integrally formed with and are disposed at right angles to the

portions

2, 2, of the hinge, the members 1 being bent as shown in Fig. 5 to form the

portions

2 and 4, as shown.

At the bent portion 5 of the members 1, I provide a pair of

elongated apertures

6, 6, which are transversely spaced apart and are also spaced inwardly from the outer edges of

members

1, 1. Said apertures are of such width to accommodate a pair or more of links 7, as shown in Fig. 7 and one or more of the abutments S such as is shown in Fig. 6. The links 7 are'slightly elongatedand have spaced bores 9 and 10 therein which are adapted to receive

hinge pins

11 and 12 resection of the same on line spectively. Said links also have an elongated central portion 13, and reduced

portions

14, 14, at the ends thereof, whereby

shoulders

15,15, are provided at the ends of the portion 13. V

The abutments 8 are of triangular form and constitute ribs for bracing the

opposite members

1, 1, against each other. Said members have bores 16 formed therein and an enlargement 17 partially surrounding said bore, while the right

angular edges

18 and 19 of member 8 is cut away below the edges 20 and 21 of said enlargement, so as to provide shoulders 22, 22, at the extremes of said enlargement, and the bore 16 is adapted to receive the

hinge pins

11 or 12, as the case may be.

The

hinge pins

11 and 12 are inserted in the bores 9 and 10 of the link 7 and the bores 16 of the abutments 8, one of said abutments being positioned between a pair of said links on each of the pins 11 and'12, and a complete set of said members including a pair of links and a single abutment is mounted on each of the members 1, and near the outer edges thereof, as shown, the links 7 being extended through the

openings

6, 6, in the members 1, and the pOItiOllSl, 4, of

members

1, 1, being positioned in abutting relation, as shown.

Now, when the

straps

1, 1, are extended as shown in Fig. 1, the edges 13 of links 7, and the edges 21 of abutments8 will be held in the

openings

6, 6, in the straps and flush with the upper surface of the straps, and the

shoulders

15, 15, of the'links, and 22, 22, of the abutments will rest almost or not quite against the edges of the

openings

6, 6. Likewise the edges 19- of the abutments will engage the lower surface of the

portions

2, 2, of the hinges, while the edges 18 thereof will engage the depending portions 4:, 1, and thus serve to hold the hinge together, so that the

members

1, 1, may be adjusted relative to each other without dis-assembling the hinge, and the links 7 and abutments 8 will at all times be held in the position shown when the members l, 1, are moved into any position about the axis of the

pins

11 and 12.

The abutments 8' are adapted to be in serted in kerfs or grooves cut in the members T and T, as'at 23 in Fig. 2, and the

straps

1, 1, are adapted to'be countersunk in the upper surfaces of members T and T as in the case of ordinary strap hinges. Thus, it will be seen as shown in the drawings, that

theopposite members

1, 1, of the hinge are pivotally connected together by means of the links 7 7, and the

hinge pins

11 and 12 at two spaced points, and the hinge when extended as shown in Fig. 4 will be held in the position shown by means 4 of the

shoulders

15, 15, on the links 7 which engage the ends of the apertures 6 in the straps. i

The .braces 8 are held between a'pair of the links 7 as shown, and the shoulders 22 thereon also engage the ends of the openings 6. N ow, when the hinge is attached to two relatively movable members, as at T and T, said members maybe extended into horizontal alinement as shown in "Figs. 1

and 2, and held without any braces other than the

members

8, 8, etc., which serves to reinforce the hinge and hold the leaves of a table or extensible shelf in extended position.

It will be readily apparent that I may form the hinges of any suitable or necessary Width and that I may provide as many of the

members

7 and 8 as may be necessary to accomplish the'objects of my invention.

While I have shown my improved hinge in connection with a table top, I may also use my hinge in other cases where a flush hinge is required and where it is necessary to provide, or desirable to do so, a rigid firm support for an extensiblemember.

As shown in Fig. 8 it will be observed that the

members

1, 1, may be folded backwardly into contact so that the members T and T which are connected by the hinge may be folded in like manner.
