INVISIBLE HINGE.

Specification of Letters Patent.

Patented Oct. 29, 1907.

Appuomon nessuna 24.1907. sesam. 380.576.

declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to whichl it appertains to make and use the same.

My invention rela'tes to invisible hinges for cabinets, pianos, or other articles of furniture, and wherever a particularly neat appearance is desired.

The object of my invention is to produce a hinge oi this character which shall be at all times entirely concealed from view, and which shall permit the parts to which it is attached to open so wide that they may lie flat along side each other.

To these ends my'invention consists in providing two main sections of a hinge 'which are readily separable from each other, and which are at all times concealed by a cover.

My invention also consists in the novel combination of parts hereinafter described and particularly pointed out in the claims.

Referring to the accompanying drawingsforming a part` of this specification-Figure 1 represents my hinge with the parts to which it is applied opened out to about 90 andshowing only the cover of the hinge exposed. Fig. 2 is a sectional view taken through the top of the hinge casing, showing the various hinge members including the floating frame, in place. Fig. 3 is a sectional view, taken on the line 3-3 of Fig. 2, but also showing the parts to which the hinge is applied. Fig. 4 v

' on the line .5-5 of Fig. 2, and showing the hingecasings foldedback parallel to each other. Fig. 6 -is a sectional view taken on the line' 6-6 of Fig. 2, and showing the lhinge"casings closed as they are in Fig. 2. Fig. 7 is a perspectivel view showing one of the hinge casings, the hinge plate that goes therewith, and the floating frame. Figs. 8 and( 9 are perspective views of the bolts that vslidingly secure the parts together.

Like numbers designate like parts in all the views.

I The hinge consists of-two main sections, each section composed of 'a hinge casing .4, and a plate 11, pivoted thereto. It also consists of a cover 3, a floating frame 22, and two bolts 17.

Each casing 4 is provided with the guide horns 5, the guide plates Shaving theguide pins 7, and thecut away lower edges 8, and the hinge eyes 9. These hinge eyes 9 on one casing 4, are longitudinally displaced on the casing with respect to the corresponding hinge eyes on the other casing 4, so that the two sets of hinge eyes on the two casings 4 may come together and register in the same straight line, see- Fig. 2. Corresponding to the hinge eyes 9 on each casing 4, are another set of hinge eyes 10 on hinge plates 11, one hinge plate for each casing 4, and a plurality of short pins 20 pass through the hinge eyes 9 and 10 of each main hinge section, and of course lie in the same straight line when the parts are in the position shown in Figs. 2, 3 and 6. vThese plates 11 are provided with housings 12 having solid parts 13 cut away on their under sides at 14,and curved guides 15. Holes 16 are made through the solid parts 13 to accommodate the bolts 17, and cut away places 19 are provided next to the solid parts 13 to accommodate the curved guides l5 on opposite housings when the hinge is operated, as will appear more fully hereinbelow. Each of the plates 11 are likewise provided with cut away places 20 and 21, each to accommodate two guide plates-6 and 27, as will appear below.

The loatinglrame 22 is provided with the side strips 24, the end pieces 25, and the bottom strips 26. Each of these bottom strips are provided with two guide plates 27, one on each. side, as shown, and each plate 27 is provided with curved guide surfaces having the upp'er notches 28, the apex 29, and the lower notches 30. The notches 28 in one pair of plates are located opposite the notches 30 in another pair of plates, as shown. -The bottom strips 26 are also provided with the holes 18, as shown, and the cutaway places 31.

In assembling the parts, the two plates 11 are first hinged to the two casings 4by matching the hinge eyes 9 and 10 and by inserting a plurality of short pins 20 throughl said eyes. The two main sections of the hinge thus formed, are next brought together with their hinged sides parallel as shown in Fig. 5, and the hinge plates turned to an angle of about 90 with the said sides, in which position the guide plates 6 of the casings 4, are about one-half within and one-half without the housings 12. One of the strips24 of the oating `frame is next removed, and the bottom strips carrying the guides 27 are thrust underneath each plate 11 and between the same and the hinge edge of each casing 4, being careful to see that the said guides 27 enter the housings 12 on the plates 11, and that the pins 7 on the guide plates 6 contact with the guide surfaces 28, 29, 30 of said plates 11, as shown. In this position of the hinge, the bolts 17 may be thrust through the holes 18 from the outside, and the strips 24 that had been removed fromthe floating frame 22, may be now secured in place by solder or otherwise.

Upon opening and shutting the hinge after assembling the parts, as described, it will be found that the short pins 20 all aline, when the casings 4, are in the same straight line, as shown in Fig. 2, and that they separate, as shown in Fig. 5, when the said casings are brought parallel to each other while the floating frame seems to remain stationary and the solid portions of the hinge plates slide on the'bolts 17. The guide horns 5,. enter between the strips 24 and the housings 12, as shown, and .force the latter inward as the casings are carried from-the position shown in Fig. 5 to that shownf in Fig. 4, and finally to that shown in Fig.` 3. In opening out the casings from the position shown in Fig. 3 to that shown in'Eigs. 4 and 5, the guide horns 5, merely slide out from between the strips 24 and the housings 12, while the plates 6 on the casings 4, force the said housings to slide' outward, or apart on the'rods 17.v The casings 4 are fastened in the parts to' be'hnged, as shown, and holes 33 are provided in the plates 11, for accommodating a screw driver, when the said plates are at right angles to the hinge bottom of said casing and the screws shown in Fig. 3 are to be inserted.

It will be seen that4 the floating frame 22 remains practically lstationary with respect to any swinging movement of the housings '12, or in other words, this frame and these housings turn on a shifting pivot passing through the two sets of short pins 20. It results from this that the cover 3, will likewise .partake of the same motions, and always `occupy the space uncovered between the hinged parts l and 2, as shown in Figs. 4 and 5. The 'parts of the hinge are therefore always concealed and a neat appearance secured.

Inpractice, I prefer to make my hinge of brass, al# though any desired material may be employed, and to cast the casings 4 with the horns 5, the plates 6 and the hinge eyes 9 integral therewith. The plates 11 may be either stamped, or casa-and the floating frame with one side removed may be cast inione piece, and the said side in a separate piece, and then secured to said frame in any `suitable manner..
