`ALvIiv `n-LEIBE, or rnvineron, NEW annsny. j i


.(Applcation led September 3, 1921.` Serial 4Nb. 4983983 To all whom t may concern: i

Beit known that I, ALviNLrLEIBE, acitizen ofthe United States, residing at Irving` ton, in the county of Essex"v and State `of NewA Jersey, haveinvented certain new and useful Improvements in rEyeglasses and the.4

To obtain` a clearl `understanding of the objects of this invention,` it may be stated at this point that it is at present customary `in the manufacture of devices of this character to take a piece of spring stock for the bridge and connect thereto a knuckle piece or joint menibereither by soldering the` saine so as to make it integral or attacliing the part by means of a screw. The eye-glass rim has then `secured to it what is known in the trade as a screwhollowwire, and this is usually cut through and provided with al screw by means of which the rim is opened. and closed when inserting alens and at one end of this part is soldered a spring Areceivj ing barrel `to receive a coil spring for `actuating the glass infunfolding; To thisthe Abridge piece with its joint is connected in the usual way by arivet pin and usually the parts are suitably washered as maybe re-` quired. j'

This method of manufacture, almost universally followed, `has a number of disadvantages, among which may be mentioned that in the first place the process of mount-` ing of suchsmall parts is delicate and `tedious work and requires a number of operations, whichl makes for expense in assembling. Again, the bridgespring is necessarily foreshortened andthis materially af` fects the resiliency or flexibility w'liichis ob-l tainable andreduc'es the life ofthe bridge spring. I

It' is the object ofrthis invention to simplify materially the manufacture of these articles by so forming the bridge spi'iiig"it` self as to embody a spring container which is adapted to be connected with the joint member of a lens support whereby to obtain the benefit of increased length of the bridge spring and essentially theliexibil'ity of this part.

It isI further an object to provide a single member or connection forthe lens mounting to replace the ordinariljT separate parts, that` for receiving the clamping screw land that which receives the actuating` spring herein` before mentioned. l These and such other objects `as may hereinafter appear are attained `by the novel constructir'in,v combination and arrangement off parts to be hereinafter specifically described and claimed. Reference will/now be lhad toV the-accompanying drawings forming a part `of this'speciiication wherein:`

Figure l is affrontelevation` of a folding oxfordfconstructed in accordance withr my invention.` j j Figure 2 is a sectional view on` the line 2-2 of Figure l, considerably enlarged.

.Figure 3 is an enlarged sectional. view onv the line 3-3 of Figure 2 showing more clearly the formation of th i extremity. j

Figure 4 is a detail perspective view of the end of the bridge spring.

Figure 5 is a bottom plan view oftheI convnector piece for the lensl support. i

rlhrougliout the following detailed description and on the several figures 'o'i the like reference characters.

Referring to 'the drawings7 ldesignates a lens rimoi' supportof thc conventional tvpe.

Upon the upper part of this is attached by j llaai bridge spring j drawing, similar parts are referred to `by 9()y means ot solder or otherwise the' connector piece 2 shown most clearly in Figure 5 of the drawing. rThis part is formedof asniall` piece of sheet metalstamped or lrolled into the form shown in thefigure just mentioned extends into the main part 2 ,so as to pro-l duce the necessary clamping action.

The bridge spring 5 has each of its eX'- tremities bent into the configuration shown most clearly in Figures and liso as to forni a substantially .cylindrical spring con'-- tainer 6 which. as will be observed, constitutes the receiver for the actuating spring 7, coiled aboutthe pintle Swhich forms the inbefore described.

pivot connection between the bridge springr and the connector part orl piece 2. @ne enti `of this coil spring passes out laterally throughthe side of the part 2 adjacentto the bore for the pintle as shown at 7', while the rim as shown in Figure 3. This special conguration is utilized to obtain a .co-action between the end Aof the spring and the rim y which limits the pivotal or unfolding move-V` ment of the eye-glass or lens support.

lt will thus be seen that without departing from the conventional form of-a folding `oxford ll'have produced a simplication of the `parts Without sacrificing any of the strength which is required, but rather, on

the other hand, obtaining a much more satisi factory connection or mounting thanA isolotainable with the known constructionheref By the formation ofthe bridge spring in the manner specified, benefit is obtained of the full length of the spring part up to the pintle, thus increasing the `flexibility yof this element which is in a device of this character extremely .important owing to the fact that there is :i gre amount of strain produced by folding o lens into position upon the other, as is ens-- tomary inL these devices.

Having thus described myi invention, what `lf claim as new and desire to secure b Letters Patent is: Y

l. In a folding oxford, the combination with a lens rim, of a connector piece attached `thereto and having a bifiircated portion, a bridge spring having itsextremity returned toprovide a spring container adapted to be received within the bifurcated portion of the `connector piece, said spring container having a portion which is adapted to co-act with the rim to form a limit-ing means restricting the pivotal movement of the rim withrespect to the bridge spring, a pivot connection loe-` tween the bridge spring and theconnector piece, and a spring operatively'mounted within the springconnector.

2. ln a device of the class described, the combination of a connectormember attached thereto, a bridge spring having its extremity bent backwardly so as to form a spring container, theJ rresiliency of the bridge spring being thus renderedetliective to the en-' thereof, said container being adapted to be received by the connector member, a pintle` passing through the connector member and bridge spring, and spring means surroiinding said pintle and seated in the rbarrel nf the bridge spring v .Y f i v 3. In an optical dev-ice of thefclass described, the combination with a glass rim,

of a connector part attached thereto vand having oiie'end bifurcated to receive the end of a bridge spring, a bridge spring vhaving its extremity turned inwardlyto form a spring container, theresiliency of the bridge spring being thus 'rendered effective up to the end thereof, and apintle passing through the connector piecev andthe bridge spring container. i i l V 4, ln a foldingfoxford, the combination with. alens rinizof a connector piece attached thereto and. provided witha. cylinderbore at one end to receive a screw, said piece bein-g bifurcated at its opposite end tonreceive'a bridgespring, a bridge spring haying its extremity bent around to form a spring container adapted 'to be receivedby the con-- nector piece asluaforesaid, ,the extremity, of said bridgespring being shapedto coact with the rim to forni a limiting means restricting the pivotal movement of thek glass y'withrespect to the bridge spring, anda pivot connection between the bridge spring and the connector piece. y i 5. in a folding oxford of the 'class described, the combination with' a lens support ofV a connector piece formed ofstainped metal rolled together at one. end to provide a screw receiving bore, and bifurca-ted at its opposite end `to pivotally receive thebridge spring.. p Y

G. A s a new article of manufacture, a iiexible bridge spring strip for folding Oxfords and the like havingits extremities bentl in` wardly and aroiundto: form a, substantially cylindrical spring container. i

7.. As a newI articleof manufacture, a ilexible bridge spring stripl for holding Oxfords or the lilrehaving its extremities bent sharply inward and around to forni a= substantially.

cylindrical.container and ay flattened shoulder` or surface adapted to coact with a glass frame foiylimiting the swingingmovement of the* latter. i i u U `S.v lign a folding oxford, the combination with a lens rim, of a connector piece attached thereto and having a bifurcatedportion, a resilient bridge spring strip, having one end thereof lreturned to provide a spring container' adapted to be received within the bifurcated portionof theconnectoigthe resiliencyjof the bridge spring being thus rendered eifective to the end'thereoya pivot connection between the bridge spring and.

the connector piece, and a spring operatively mounted within the spring container.

In testimony whereof l affix my signature. ALVIN ILLEIBE.
