Application led March B. 1918. Serial No. 221.103.

To all whom it may concern:

. Be it known that I, NORMAN C. Nicol., a

- citizen of the United States of America, and

a resident of the city of Buffalo, county of Erie, and State of New York, have invented certain new and useful improvements in Hinges, of which the following is a full, clear, and exact description.

My invention relates generally to hinges and more particularly to hinges of the concealed type, and which may be used on doors, gates, window sash, piano covers, wardrobes, closets, and for various kinds of cabinet work.

The principal object of my invention has been to provide a hinge which shall be simple in its operation and very compact in its design, so that it may be attached to comparatively thin materials.

Another object has been lto provide a hinge, the construction and o eration of which is such as to prevent t e movable member, to which it is attached, when in its closed position, froml moving away from the stationary trame or support to which it is pivotally attached. t

A further object has been to provide a device which shall have such a radius of movement as to give the movable member the desired amount of throw, whereby rubbing of the parts is prevented during the operation of the hinge, and whereby the same is made adapt-able for different thicknesses of material.

The above objects and advantages have been accomplished bythe device shown in the accompanying drawings. In the drawings:

Figure 1 is a front view its open position.

Fig. 2 is a sectional elevation of my device and is taken on line 2-2 of F1 1, with the hinge members in their close position.

Fig. 3 is a front elevation of my hinge, showing the relation of parts when the same is partially closed. y

Fig. 4 is a sectional elevation taken on line 4-4 of Fig. 2, showing the inner face of one of the hinge leaves.

Fig. 5 is a transverse sectional elevation taken on line 5-5 of Fig. 1.

Fig. 6 is a front elevation of a modified form of hinge.

Fig. 7 is a longitudinal, sectional elevation of another modified form of hinge.

of my hinge in I Referring now to the drawings, and partlcularly to Figs. 1 to 5, inclusive, 10 are the casings 0f my hinge, which are preferably made of sheet metal and formed in the shape of a box, as shown. 11 may represent the stationary member and 12 the mov- -able member, to which my hinge is attached;

the casings being 1ct into the edges of these members and set in flush with the face thereof. The usual screws 13 serve to retain the casings in position.

The butts are connected by a supplemental

hlnge comprising leaves

15 and 16. flhese loaves are pivotally united at their inner ends 17 'by a pin 18, Whose axis lies midway between 'the casin s, when in their open position and paralle to the faces of the side walls thereof. The end 17 of preferablv the leaf 15' is provided with a lip 19 which contacts with the upper surface of the end 17 of the leaf 16 when the parts are in their open position, as shown in Fig. .5, so that the ends are prevented from opening through an angle greater than 180. By th1s arrangement, the leaves close readily and binding thereof is prevented. The outer end of each of

thc leaves

15 and 16 is pivotally united with one of the casings 10 by means of a pivot pin 20. These pins are opposltely arranged, each .at an angle of 45o to the face of either of the side walls of the casings and they are supported within the casings 10 by means of a *lug 21, formed preferably by bending a portion of the end wall of the casing, and by an indented portion 22, formed preferably from one of the side walls of each of the casings. The

outer ends of each of the leaves is provided with a tab 23 and a tab 24, which are bent at substantially right angles to the face of the leaves and are pivotally attached to the pivot pins 20.

It will be seen, by reference to Fig. 2, that the two leaves 15 and 16 do not fully .close when the hinge is in its closed posiin Figs. 2 and 4f.A In order to make the

leaves

15 and 16 of light material and yet of sucient strength, the edges are preferably bent up at right angles to the face of the leaf, as clearly shown in the drawings. Each of the casings is provided with a closure plate 25, which is pivoted within the casing at the end opposite the pivotal connection ofthe leaves and which is arranged to close the openings within the casings when the hinge is in its open position, as lshown in Fig. 1. These plates are mounted upon pivot pins 26 and are elevated to the position shown in Fig. 1, by means of a sflxring 33, arranged beneath each plate. The p ates are maintained in the position shown in Fig.v 1, by any suitable means, but prefeifably a tab 27, formed from the side wall of the casing and bent over at right angles so as to act as a stop for the outward movenient of the plate.

In Fig. 6, I show a modification of my hinge, where the outer ends of the leaves 2 8 are pivotally united-to the casings 29 at angles of substantially 30 withwthe side wall of either of the casings 29.` AOne of the leaves 28"is shown in its closed position by the dotted lines in the left hand casing of Fig. 6. This View shows that, the pivot pins at the outer ends of the hinge leaves need not necessarily be arranged at an angle of 45 with the side walls of the c asings, but that this angle may be made 30 or varied to any other suitable angle. v v -I In Fig. 7 where I show another modified form of my invention, all the 'pivotal pins have their axes arranged in parallel planes. Thus the pivotal pins "3 1 for the, outer ends of the leaves are arranged parallel to each other when completely closed or open and each always parallel to the central pivotal From the foregoin 1t will be seen that my hinge is'very compact in its design and requires the use of a comparatively few parts, thus making itvery durable and not liable to get out of order. As shown in Fig. 3, my hinge when opening separates the parts to which it is attached, so that they have `reached 'nearly the maximum separa-- tion when opened to an angle of 90. Morerover the connections of all the parts in myhingeyare pivotal, thus doing away with all .sliding connections and the resulting friction.

From the' foregoing, will be seen that the leaves of the supplemental hinge are so1 mounted that when the casings are moved toward or from each other, the central pivot of lthe supplemental hinge leaves will move through a plane which is at right angles with the plane of rotation of the casings and assume constantly different angular relations with the casings.

While I have shown and described. the leaves of my supplemental hinge as having an angular connection with the casings of substantially 45 and 30, it is obviousfthat the parts may have any desired angular re,- lation.` plate 25 may be omitted, and the pivot pins tion o f my invention, it is preferably advisable, 1n order to secure the required stabil ity, to use more thanA one supplemental hinge. v

It will be clearly understood, however, from the foregoing description that when a plurality of supplemental hinges is employed, it will be a duplication of the single structure .herein shown and described. These and other 'modifications of the 'details herein shown and described may be made without departing from the spirit of my invention or the scope`of the appended. claims, and I do not, therefore, wish to be limited to the exact embodiment herein shown andA de- Furthermore, if desired, the closure f for the inner ends of the leaves may be ar- `ranged in parallel planes or in planesat an angle to each other. Owing to the construc-4 ico ings, a two-leaf supplemental hinge pro-` vided with a central pivot, a pivot pinfor the outer end of each leaf of the supplemental hinge, each pin being mounted in the casings and angularly arranged with respect to the faces of the side walls of the casings, and means for preventing the supplemental hinge members from opening through an angle greater than 180. 3. A hinge comprising box-shaped casings, a two-leaf supplemental hinge provided with a central pivot, a stop carried by' one of the leaves of said supplemental hinge and arranged 'to engageV the other leaf of said hinge, a pivot pin for the outer endr of each leaf of the supplemental hinge,l each pin'being mounted in the casings, and means,

for supporting the pivot, pins.

4f. A.o hinge comprising box-shapedy casings, a two-leaf supplemental hinge provided with a central pivot and a pivot pin for the outer end of each leaf of the supplemental hinge, each in beingmounted 1n the casmgs and angu arly arranged with respect 4to the faces of the side walls f the casings, and a closure plate disposed within each of the casings arranged to close the opening of each of the casings when the hinge is in its open position.

5. A hinge comprising` box-shaped casings, a two-leaf supplemental hingejy provided with a central pivot, a pivot pin for the outerwlend of each leaf of the s pplemental hlii'ge, each pin being mountfed in the casings and angularly arranged'. with respect tothe faces of'the side wallsv of the casings, and a closure plate pivoted within each of the casngs and arranged to close the opening within the casings when the hinge is in its open position.

6. A hinge means comprising a plurality of .box-shaped casings, and a plurality of supplemental hinges, I each supplemental hinge comprising two leaves having a commonV central pivot, and pivot pins for the outer ends of each of the supplemental hinges, the last mentioned pins beingmounted in the casings and angularly arranged with respect to the top faces of thecasings, as Well as the faces of the side walls thereof.

In testimony whereof, I have hereunto signed my name.
