Application filed August 29, 1914. Serial No. 859,155.

To all whom t may concern Be it known that I, HENRY E. LEIBn, a

citizen of the United States, residing in the city of Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Folding Eyeglasses, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it' pertains to make, construct, and use the same, reference being had to the accompanying drawings, and tonumerals of reference marked thereon, forming a part of this specification.

This invention relates to improvements in folding eye-glasses, and has for its object, to provide the lens frames thereof with casings curving outwardly from said lens frames and projecting toward each other, said casings having pivotally secured thereto springactuated nose guards, and a spring-actuated bridge so arranged that the lens frames may be folded one upon the other.

Further objects of the invention are to simplify the general construction and operfront elevation of my improved device.`

Fig. 2 represents a plan view ofthe same.

Fig. 3 represents a similar view, illustratf ing the device in folded position. Fig. 4: represents a rear view of my improved device. Fig. 5 represents an enlarged and detached view of the bridge; and Fig. 6 represents a transverse section taken on line x-x of Fig. 2.

Referring to the drawings, 1 represents the frames for holding the lens and 2 the lenses, which may be of any desired form or configuration.

3 represent chambered casings or bridgesecuring means carrying the nose guards and which are secured to the lens frames in any convenient manner, preferably by solder, curving outwardly from the lens frames and projecting toward each other.

A spring-actuated bridge 4 provided with tubular ends 5, is pivotally connected to the casings 3, 3 at the ends thereof by means of split-pins 6, and so arranged that the lens frames 1 carrying the casings 3, to which are pivotally secured the spring-actuated nose guards 7, may be folded one upon the other, as clearly indicated in Fig. 3 of the drawings.

y A handle 8 on one end of the lens frame is provided with a guide-way, to receive the other lens frame, and is further provided with a spring-catch 9 for engagement with the entering lens frame, to lock the lens frames in folded position.

The chambered casing 3 is preferably channel-shaped in cross-section, (see Fig. 6), between the walls of which a tubular post 10 is rotatively located, the lower end of which is slotted as at 11 to receive the flattened end portion 12 of the nose guard 7.

A split-pin 13 is rigidly secured in the walls of the casing and passesthrough a suitable aperture in the end portion 12 of the nose guard, and through the tubular post 10, by means of which the parts are held in position. A spiral spring 111 is located within the post 10 and surrounds the pin 13, one end of said spring being secured in the slot of the pin and the other end is located in the slotted portion 11 of the post 10. Similar pins 6 secured to the outer ends of the casings 3 and passing through the tubular ends 5 of the bridge 4, have one end of a spiral spring 15 secured thereto in the same manner, the other end of which is secured to the tubular ends 5 in any desired manner.

Suitable stops 16 preferably formed integral with the upper portion of the bridge l and in close proximityV to the tubular ends 5 are provided to properly position the parts when in folded position, as clearly indicated Y in Fig. 3 of the drawings.

The chambered casings or bridge securing means are further provided with an elongated slot 17, to receive the fiattened end portion 12 of the nose guard 7.

Experience has demonstrated that the organization above described is a highly eiiicient one, and while the device described is the preferred embodiment of my invention, I do not wish to be limited to the exact details of construction and combination herein set forth, as minor variations thereof not involving the exercise of invention, may be made by any skilled mechanic, and such departures from what is herein described and claimed, not involvinginvention, l vconsider `Within the scope and terms of my claims.

I claim l. A pair of eye-,glasses comprising lenses, f

frames for holding the lenses, bridge-securmg means on said'lens frames, spring-actu-l ated nose guards `pivota'll'y secured to said' bridge-securing means, a `'spring-actuated `bridge 'pivotally connected tothe ends of said bridge-securing means and so arranged that the lens -framesmay be foldedvone upon the other, a handle on one ofthe lens'V frames l and locking meansY on the handle for engagetoward each other, each of said bridge-scour?,-

ing Ymeans `being provided With a slot, springactuated nose guards provided With flattened' end portions pivotally secured to said bridge-securing Vmeans, said flattened end portions projecting throughv the slots in said Vbridge-,securing means, a spring-actuated bridge provided with stops, pivotally connected to the ends of the said'bridge-se! curing means and so arranged' that the lens framesl may be properly positioned andl folded one upon the other.

3lV A pair of eye-'glasses comprising lenses,

frames for holding the lenses, bridge-securing means on said lefns'frames projecting toward each other, each of said bridge-sewn.

ing means beingV provided with a slot, spring-actuated nose guards provided lWith flattened end portions pivotally secu'red'to said bridge-'securing means,V said flattened end portions projecting'throu'gh the slots inV said bridge-securing means, a springactu! ated bridge provided with stops, pivotally connected to the ends ofthe said bridge-securing means and so arranged that the lens frames. may, be properly positioned and folded one upon the other,'a handle on one Copies of `this Vpatent may be obtained for :five cents each, by addressing the Commissioner Washington, D. C.

4. A pair of eye-glasses comprising lenses, frames for holding the lenses, slotted channel-shaped bridge-securing means on said lens frames projecting toward each other, spring-actuated nose guards provided with flattened end portions pivotally secured to said bridge securingmeans, said flattened end portions projecting through the slotted bridge-securing means, a spring-actuated bridge provided with tubular ends, and stops formed integral with the upper portion of the bridge in close proximity to the tubular ends pivotally connected to the ends of said bridge-securing means and so arranged that the lens frames may be properly positioned and folded one upon the other.

5. A pair of eye-glasses comprising lenses, frames for holding the lenses, channel* shaped bridge-securing means on said lens frames projecting toward each other, a post rotatively located in each of said bridge-securing means, the lower end of said post being. provided with a slot, spring-actuated nose guards provided With attened end portions pivotally secured to said bridgesecuring means, said flattened end por-` tions projecting through the slots in said lbridge-securing means and said tubular posts, a spring-actuated bridge provided with tubular ends and stops formed integral with the upper portion of the bridge in close proximity to the tubular ends pivotally connected to the ends of said bridge-securing means andvso arranged that the lens frames maybe properly positioned'and folded one upon the other.
