county of Cookv and Statehof Illinois, have invented certainnew and useful Improvements in Eyeglasshlouiitings, of wliieh'the following is a specification.

This invention relates mor the fraineless type ofi eyeglasses, and .has for its different objects First-,eto provide a simple and efficientconstruction of 'the manually actuated lever 'tand nose piece or' grip, and involving the ready, andv economilcal production of said' parts'as one piece, with the retention of the original resiliency of the metal from which [said members areforined. Second,V to provide a siinplevand efficient one piece construction ofthe-,s ring for. actuating the nose grip carrying lever, withl which the attachment ofthe spring to the eyeglass bridge is attained in simple and very substantial manner. All' aswill hereinafter more fully appear. i

1n the accompanying drawings: Figure 1, is a perspective lview of a riniless eyeglass mounting, with the lensto the left removed to more effectively illust-rtitehthed'etail construction and arrangement of the present invention. Fig. 2,is a pers iective view of the arched bridgeand attac iing clips, the

' nose piece' or grip and carrying lever, `the spring and the pivot screw, in a detached conditiom Fig.l 3, is an elevation ofthe blank or stamping from which the nose grip spring is formed.v Fig'. 4, is a similar view of the blank or stamping from which theI integrally connected nose grip `and carry-l ing lever Vare formed. Fig. 5, is a detail perspective view of a modified constructionl of the carrying llever ofthe nose lpiece orv srip- ,o n

Similar numerals of reference indicate like parts in the several views. U

Referring to the drawings, ll represents the rirnless lens of a pair of eyeglasses,and 2 the rigid archedbridge 'connecting the lenses together in proper spaced relation.`

3 are attaching clips provided with resilient bracing members 4, said parts beiner preferably of an integral construction with rthe arched bi'idge 2, aforesaid, in manner set forth in detail in iny companion application for patent Serial No. 486,485, filed on an even date herewith.

5 are the leverswhich carry the nose piece well "or grips hereinafter described. Said leversV extend transversely ofthe bridge 2 andare -pivoted thereto,"about midway their'length -by the pivot screws 6 screwing into the pivot Patented sept; zo, 1910.

enlargements 7 at the base of the arched portion vof the bridge asshown. The for- 'ward arms of the. levers are curved out- "Wardly and endy in enlarged skeleton finger ',pieces 8, of an approximate-ly U form, and adapted to be manipulated by the fingers of vthe user as usual 'in the present ty e of eye-l glasses. The reararms of said' evers are of an' z 'pproxgnnately 'straight form and end in ,resilient loops 9 which connectl the levers vto' the `respective nose iecesor grips 140. In

the'prefei'red form o the resent improvenient each lever with its in ividual grip, as

s the ls ring engaging hook herein- 'after Y escribe are integrally formed from 'a single blank or stamping of the fiat forni shown-in Fig. 4, and subsequently bent and otherwise mani ulated to form the completed article il ustrated in Figs. 1- and 2; the' object being to provide economy in manufacture ane4 to preserve the original resiliency of the material, which resiliency would be affected more rless by the heat were thel parts made separate and asseinbled by theusual brazing operation.

10 are the nose pieces oi grips above referred to, and pre erably comprising main body portions curved in reversed directions and. ending 4in return bends 11 ofV a lobular form, as set forth in detail in my applica- 'tion Serial No. 500,413. v r

1,2 are spi-ings individual to the levers 5,`

and which in the present improvement are formed from `flat blanks of the form shown in Fig.r3, eac-li `blank comprising a rectangular 'end portion 13 formed with acentral orifice 14, and an elongated tongue offset from said end portion 13 as shown. In forming 'the sring from said blank, the rectangular en portion 13 and elongated tognue 15 are bent into right-angle relation to each other, after which the middle ortion of said tongue is bent into a volute orm around an axial line passing through the orifice 14 aforesaid, and in a planea small distance removed from the end portion 13 so as to leave a space between the two or-V tions, and so that said portions ma stra die the arched bride 2 of the ey'eg ass when the parts are assembled. The free end of said tongue 15 extends awa from the volute portion aforesaid and is a apted to engage tongue on said lever, bent into a stirrup shape as shown. With the described arrangement, the connection of the tongues or extensions 15 of the springs 12 to the levers 5, are made at distant points from the pivot axis of said levers, andv said extensions are thusutilized to attain increased smoothness and uniformity in the ceiling and uncoilingof the springs.

In an assemblage of the parts above described, the spring 12 will be engaged with the arched bridge 2, as above described, after which the lever 5 is superimposed above the spring, and tlie attaching screw G inserted through the parts to effect the desired pivotal connection.

In the vmodified forni of the nose grip lever 5 shown in Fig. 5, the lever is shown as a separate piece, and is rigidly connectedto a nose piece or grip by a rectangular stirrup formation 17 on its rear end, into which the central port-ion of the nosegrip' fitsV and is secured by an attaching screw. In order to provide the proper thickness of metal at the heel of the stirrupformation 17 to receive the attaching screw the metal of said' stirriip is folded upon itself as shown. f

Having thus fully described my said in- Aveiition what I claim as new and -desire to secure by Letters Patent, is :--l

1. In an eyeglass of thetype herein described, the combination of a rigid arched bridge, a pair of levers pivoted thereon at opposite sides of the arch of said bridge, nose grips carried by said levers, and opera-ting springs of a. volute form interposed between the levers and the bridge and protected thereby, the inner ends of said springs being connected bo the bridge and the outer ends to the levers, substantially as set forth.

2. In an eyeglass ofthe type lherein described, the combination of a rigid arched bridge, a pair of levers pivoted thereon at opposite sides of the arch of' said brid e and provided With stirriips. at the rear o their points of pivotal attachment, nose grips carried by said levers, and'operating springs of a Ivolute forni interposed between 'thel levers and the bridge and protected there-'- by, the inner ends of said springs being connected to the bridge and the outer ends to the aforesaid stirrups of the levers, substantially as set forth.

3. In an eyeglass of the type herein described, the "combination of a rigid arched bridge, a y.pair of levers pivoted thereon at opposite sides of the arch of said bridge,

nose 'grips carried by said. levers, each leverv havingan intermediate resilient loop and spring attaching. stirrup, and springs atl tached to the bridge between said bridge and the levers, said springs surrounding the pivot axis of the levers and having extensions or tongues engaging the aforesaid attaching stiiriips of the levers, substantially as set forth. A

elf. In an eyeglass of the type herein described, tlie combination of a rigid arched bridge, a pairof levers pivoted thereon at l opposite sides ofthe arch of said bridge, nose grips carried by said levers, and springs interposed between said levers and bridge, each spring comprising a, -iat oriiced end 'portion and an elongated tongue portion bent 'into a volute form, the two portions of y tlie spring being separated to forin a receiving cavity for the eyeglass bridge, substantially as set forth.

5. In an eyeglass of t-lie type herein described, the combination of a rigid arched bridge, a pair of levers pivotedthereon atopposite sides of the 'arch` of said bridge, nose grips carried by said levers, and springs interposed between said levers and bridge,-

each spring comprising a atoriced end portion and an elongated tongue' portion entl into a volute form and having a pro-` jecting end engaging a lever, the'twoortions of the spring being separated to orm a receiving eavityifor the eyeglass bridge,

substantially as set forth.
