In Great Britain September 2, 1929 4 Claims.

This invention relates to hinges for spectacles, eyeglasses and the like and has for its object to provide hinges for hinging the bridge or nosepiece of folding spectacles to the eye rims which will be neat in appearance and of robust construction.

Hinges according to my invention comprise essentially a hinge leaf integral with the bridge or nose-piece of the spectacles or eye-glasses, a second hinge leaf or leaves integral with a shaped fastening plate adapted to be secured to the rims or eye-pieces and a shoulder integral with said fastening plate to limit the position of the eyepieces relative to the bridge when the spectacles are in open position.

What may be termed the second hinge memberthat is the hinge element which is adapted to be secured to the rims or eye-piecesmay have a single hinge leaf but the construction I prefer is where there are two hinge leaves on this member between which a single hinge leaf on the other hinge element is pivoted.

An important feature of the invention is the provision of a shoulder on one hinge member cooperating with a stop or shoulder on the other hinge member so as to limit the opening movement of the hinge the arrangement being such that when in open position the adjacent surfaces of the parts of the hinge are all flush one with the other and present a smooth surface.

In the accompanying drawing I have illustrated typical examples of hinges constructed and adapted to operate in accordance with my invention.

In this drawing I shows in perspective one form of hinge and Figures 2 to 8 similarly illustrate modified constructions.

Referring to this drawing in which like numerals of reference indicate corresponding parts and wherever occurring the numeral I indicates a hinge leaf formed integral with the bridge or nose-piece 2 of a folding spectacle. The numeral 3 designates the fastening plate of a second hinge member, this fastening plate being adapted to be secured in a recess cut in the frame of the rim or eye-piece of the spectacles by riveting through the rivet holes 4. This fastening plate carries a hinge leaf 5 which is pivoted to the hinge leaf I by means of a pivot or hinge pin passing through the holes 6 and I, which, when, the two parts of the hinge are in engagement, coincide with each other. A shoulder or stop 8 is provided on the second hinge member and when the spectacles are in open position for use the side edge of the hinge leaf I abuts closely against this shoulder as shown so as to limit the opening rn'ovementof the hinge to bring theeyepieces to the desired position.

The construction shown in Figure 2 is much the same as that shown in Figure 1 except that a stop 9 projects from the hinge leaf I and co-operates with a recess Ill cut in the shoulder or stop 8.

In Figure 3 a stop member I I depends from the hinge leaf I and embraces the hinge leaf 5 which in this case is circular in form.

The arrangement shown in Figure 4 is slightly different in that both the hinge leaves I and 5 are circular and the bridge 2 is thickened at its end and a curved recess I2 is provided to accommodate the hinge leaf 5 and the shoulder 23 abuts against the wall of the hinge leaf I on one side only to form the limiting stop. In all the above cases two leaf hinges are shown.

In Figures 5 to 8 similar arrangements having three leaf hinges are shown. That is to say the hinge leaves on the second hinge member-that member which is secured to the spectacle frames or eyepiecesare duplicated and designated 5 and 5 and the hinge leaf on the ends of the bridge are housed between the two hinge leaves 5 and 5 Figure 5 shows a three leaf hinge on the lines of the hinge shown in Figure 1. Figure 6 shows a three leaf hinge corresponding to the two leaf hinge shown in Figure 2. Figure 7 shows a three leaf hinge corresponding to the two leaf hinge shown in Figure 4 and Figure 8 shows a three leaf hinge corresponding to the two leaf hinge shown in Figure 1.

Hinges of the foregoing character are neat in appearance and strong and durable in use.

It is to be understood that the use of the term integral in the specification and claims is not to be taken literally as it is intended to include cases where the parts are made separately and soldered or otherwise amalgamated into a rigid structure.

What I claim and desire to secure by Letters Patent is: r r

1. A hinged bridge for folding spectacles comprising a rigid bridge element, a hinge leaf integral with and projecting laterally from each end of the bridge element, and a pivot bearing in each hinge leaf, in combination with hinge elements for attachment to spectacle eye rims, said hinge elements each comprising a fastening plate provided with rivet holes for attaching to a face of the eye rim and a hinge leaf integral with and in the same plane as the fastening plate,,an upstanding shoulder located between the fastening plate and the hinge leaf and integral therewith to limit the position of the eye-pieces when the V spectaclesjare in open position, and a pivot beara 7 a ing in each leaf adapted on assembly with the bridge to come into alin'ement with the pivot bear- I ing of the bridge leaf to receive a pivot pin.
