INVISIBLE HINGE.

Speccation of Letters Patent.

Patented Sept. 24, 1912.

Application filed January 4, 1912. Serial No. 669,302.

To all 'whom 'it may concern:

Be it known that I, EMIL ZUGKERMAN, a citizen of the United States, and a resident-r of Yonkers, in the county of Vestchester and State of New York, have invented a new and Improved Invisible Hinge, 'of which the following is a full, clear, and exact description.

The obj ect of the invention is to provide a new and improved invisible hinge for use on doors, boxes, pianos, furniture and other articles and devices, and arranged to be invisible when the door lor 'other movable member is in a closed position, and to provide a space between lthe movable member and the fixed member when the door is opened. For the purpose mentioned use is made of attaching members arranged for attachment to the fixed and movable parts of the device on which the hinge is to be used, and links mounted to slide one on the other in the direction of the length of the links, the links being pivotally rconnected with and guided by the attaching members.

A practical embodiment of the invention is represented in the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a sectional plan view of the invisible hinge as applied to a door and door casing, the door being shown in closed position and the section being on the line 1 1 of Fig. G; Fig. 2 is a like view of the same with the door partly open; Fig. 3 is a similar view of the same with the door fully open; Fig. 4 is a face view of the same; Fig. 5 is a sectional face view of the same on the line 5--5 of Fig. 1; Fig. 6 is a similar view of the same on the line 6--6` of Fig. 1; Fig. 7 is a cross section of the same on t-he line 7-7 of Fig. 5; Fig. 8 is a sectional plan view of a modified form of the hinge as applied to a door for allowing the latter to swing inward and outward, the door being` shown in closed position; Fig. 9 is a similar view of the same showing the door open; Fig. 10 is an inverted sectional plan view of the same on the line 10-10 of Fig. 11; and Fig. 11 isa sectional side elevation of the same on the line 11-11 of Fig. 8.

As shown in the drawings, the hinge is applied to a door A and a door casing B, and the hinge is provided with attaching members C and D of approximately box y shape and mortised inthe adjacent ends of the door A and the door casing B and fastened thereto by screws E, as plainly indicated in Fig. 4. The attaching members Gand D are connected with each other by links F and G mounted to slide one on the other in the direction of the length of the links, the link F being provided between its ends with a pivot F journaled in the attaching member C, and the said link F is provided at the end extending into the member D with lugs F2 engaging segmental guideways D formed in the member D at the top and bottom thereof. The link Gis provided with a pivot G journaled in the top and bottom of the attaching member D; the end of the link G extending into the attaching member C is provided with a lug G2 engaging .guideways C formed in the top and bottom of the attaching member C. Thus the link F is fulcrumed in the attaching member C and engages the guideways D in the other attaching member D, and the link G is fulcrumed in the attaching member D and engages guideways C in the attaching member C. In order to slide the links F and G lengthwise one on the other the links are provided with longitudinallyextending ribs F3 and G3 engaging corresponding grooves in the links F and G (see Fig. 7). Now when the door A is in a closed position the hinge is completely concealed as the links F and G are contained within the attaching members C and D. Vhen the door A is swung into an open position it swings on the pivot F of the link F as a fulcrum but the link F slides on the link G and the latter swings on its pivot G in the member D. Now the guideways C and D are made segmentaland eccentric relative to the pivots F and G so that when the door A is swung open the latter is held spaced from the casing B owing to the lugs F2 and G2 traveling in the segmental slots D and C.

From the foregoing it will be seen that the links F and G pivoted in the attaching members C and D are mounted to slide one on the vother in the direction of the length of the links, and the link F is guided in the attaching member D and the link G is guided in the attaching member C. In order to permit Ithe links F and G to pass the pivots G and F the said links are provided with cut-out portions F, G4 at or near the middle thereof, and the ends of.

the links F and G are provided With recesses F5, G5 adapted to engage the corresponding lugs G2, F2 (see Fig. 3).

In the modified term illustrated in Figs. 8, 9, l0 and ll, the attaching members C2 and D2 are secured to the door A and the door casing B in the same manner as above described relative to the single hinge shown in Figs. l to 7, and the said attaching member' C2 and D2 are providedv With double guideways C3, -Da engaged by lugs H and I of links H and I provided at their inner ends with pivots H2, I2 journaled in the attaching members D2 and C2, respectively. The inner ends of the links H and I are also provided with saddles H3, I3, of which the saddle H3 slidingly engages the link I and the saddle I3 slidingly engages the link H, so that the links H and I slide one on top of the other in the direction of the length of the links. The pivot H2 of the link H is provided with a lug H4 engaged at its opposite faces by springs J, J attached to a stud J 2 secured to the attaching member D2. Then the door A is swung into an open position in one direction, as shown in Fig. 9, then the lugs H and I travel in one portion of the double guideWays C3, D3, at the same time the pivots H2, I2 turn in their bearings in t-he att-aching members D2, C2 so that the spring J is placed under tension, and when the door A is released the spring bears on the lug H4 with sufficient force to return the door A to closed position. When the door A is sivung open in an opposite direction then the lugs H2 and I2 travel in the other portion of the double guideways C3, D3, and the spring J is now placed under tension and When the door A is released the pressure of the spring J on the lug H3 causes the door A to swing into closed position.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:
