EYEGLASS-MOUN'TING.

T all whom it may 001': (cm

Be it known that I, Lno F. ADT, of Albany, in the county of Albany and State of New York, have invented certain new and useful Improvements in Eyeglass-Mountings; and I do hereby declare the followingv of the lenses toward and from the nose and under .the action of resilient means, such as springs, operating portions or finger pieces being provided for separatingthe guards, and an object of the invention is to provide a construction in which the guards are so arranged that the pupilary distance of the mounting may be reduced to a minimum and the springs are so positioned that their removal is not necessary to the removal of the guards.

To these and other ends the invention consists in certain improvements and combinations of parts all as will be hereinafter more fully described, the novel features being pointed out in the claims at the end of the specification.

In the drawings: Figure 1 shows in enlarged front'elevation a mounting constructed in accordance with this invention, one of the guards and its spring being removed; Fig. 2 is an enlarged plan View of the mounting of the same parts removed; Fig. 3 is a cent 'al vertical section transverse to the plane of the lenses; Fig. t is a bottom view of a portion of the mounting in proximity to one of the guards; Fig. 5 is atop view of a modified form of the mounting in proximity to one of the guards, and Fig. 6 is a perspective view of one of the guards.

Inthe illustrated embodiment the lenses A are connected by a support comprising preferably a bridging portion 1, lens attaching devices or mounts 2, and portions 3, connecting the ends of the bridging portion with the lens attaching devices.

' To the end that the distance between the Specification of Letters Patent.

ends of the bridging and the lens attaching devices may be reduced to a minimum, the bridging portion is formed with hearing portions 4 near its ends to cooperate with bearings on the guards, each of the latter being held against looseness on its bearings 4 by a seat 5 formed on the upper surface of one of the connection portions 3 to engage the under surface of the guard and by a shoulder (3 extending outwardly from the bridging portion above the bearing 4 and engaging with the upper surface of the guard, so that while a. swinging movement substantially in a horizontal plane is provided, all vertical movement which would destroy the rigidity of the mounting is prevented. The guards in this instance each comprise a nose engaging member 7 having upper and lower pads and connected to the rear end of an operating lever 8 which may be made from flat stock and have at its inner edge a laterally opening bearing recess 9 for cooperation with a bearing 4 on the bridging portion 1, a linger piece 10 being provided at the forward end of the lever and being connected thereto by a downward or vertical bend or turn 11. Each lever may have its edge opposite its bearing recess 9.

provided with an upwardly turned and longitudinally extending flange or rib 152 which serves to strengthen the leverat the point where it is weakened by its recess. Projections 13 and 14 may also. depend from the outer edge of the lever to cooperate respec tively with the front and rear edges of the connecting portion 3, this being particularly desirable when the lengths of the connecting portions are increased for greater pupilary distances, as illustrated in Fig. 5, when the guard levers cannot cooperate with the lens attaching devices as is customary in mountings of this type.

The springs for positioning the guards are each preferably in the form of a coil 15, arranged below the support in advance of the turning axis of the guard and outwardly beyond the ends of the bridging portion so as to be hidden by the finger piece 10, one end 16 of the coil being extended rearwardly and secured to the under side of the support preferably by a socket 17 mounted at the junction of the connecting portion 3 and the lens attaching device 2. The other end of the coil is in the form of a spring arm 18 extended rearwardly beneath the support and cooperating with the guard in rear of the turning axis of the latter, a depending hook 19 being provided on thcinner edge of the guard lever in rear of the turningaxis to receive the hooked end 20 of the spring.

To operate the mounting, the finger pieces 10 are pressed together, thus separating the nose engaging portions 7 and permitting the mounting to be placed upon the nose of the wearer or to be removed therefrom. The

finger pieces are released when the desired position of the mounting is reached, thus permitting the springs to move the nose engaging members 7 toward each other@ The removal of 'a-guard is effected by detaching its spring arm 18 from the hook 19, thus permitting the guard to be moved outwardly from beneath its shoulders 6 and off the seat 5. The spring remains with the mounting but may be detached therefrom by withdrawing its end 16 from the socket '17.

An eyeglass mounting constructed in accordance with this invention may have its pupilary distance reduced to a minimum as it is not necessary to provide pivots between the bridge ends-and the lens attaching devices, the bridge ends themselves serving as the bearings for the guards. The springs for positioning the guards are supported in dependently of the bridging portion and be neath the support so that it is possible to utilize the entire inner surface of the bridging portion for cooperation with the nose.

In addition the springs are so located that they are shielded or partially covered by the finger pieces. The mounting presents the further advantages that its parts are capable of being quickly replaced by others for the purpose of repair or for adaptation to the, facial characteristics of a wearer.

I claim as my invention:

1. In a finger piece eyeglass mounting the combination with a support having a bearing thereon, and a guard lever having a bearing turning in engagement with the support, of a spring for positioning the guard embodying a coil located in front of the turning axis of the guard and an arm ex- 'tendingrearwardly from the coil'andcooperating with the guard in rear of its turn ing axis.

2. In a finger piece eyeglass mounting the combination with a support comprising a bridging portion, a lens attaching portion and a portion connecting the lens attaching portion with the bridging portion, of a nose guard embodying a lever arranged to swing above the" connecting portion, and a spring for positioning the guard embodying a coil arranged in front ofthe turning embodying two rearwardly extending arms passing on opposite sides of the pivot of the guard lever and connected by a bend forwardly of the pivot, one arm being arranged to'act against one of said first mentioned parts and the other beingarranged to slidably engage'the other. i 1 V .4. In a pair of finger piece eyeglasses, the

combination with the lenses, a bridge or equivalent member for connecting the lenses together, nose gripping members having pivotal'connection with the said bridge member, sprlngs for actuating the said nose gripping members to cause them to grip the nose of a wearer, one end of each of the said springs being in contact with thefixed part of the eyeglasses and extending thence forwardly and transversely of the plane of the lenses, thence inwardly and rea-rwardly, and the other end of. each of the said springs having operative connection with the said nose gripping members, and means for detachably securing the said springsin position. 1

5. In a finger piece eyeglass mounting the combination with a support for the lenses comprisinga bridging portion, a lens attaching device and a connecting portion between the bridging portion and the lens attaching device, of a guard embodying a lever mounted to turn above the connecting portion and having its forward end extending downwardly in front of the connecting portion, and a spring for positioning the guard embodying a coil arranged behind the:

downwardly extending portion of the guard lever and in front of the turning axis of the latter, and an arm extending rearwardly from the coil beneath thesupport and co-' operating with the guard in rear of its turning axis. 7
