l Application tiled November `27. 1891. Serial No. l13,25 9. (No model.)

To all whom zizi may concern:

lie it known that l, ANTHONY J. BELLATI,

nsuhject of the King of italy, having decla-redmy intention of 'becoming n citizen' of the United States, and residing et the city of Philadelphia, in the county of Philadelphie sind Stnteof .Pennsylvanim hnveinvented certain new and useful improvements in Eye l glasses, of whichthe following is n specificol tion.

lily invention relates in gcncrnl to eyeglasses, and more pnrticulnrly tothe construction and arrangement of the various parts or devices thereof cooperating collectively for retnining the seine to piece upon the nose of thc wearer and individually for supportingthe lenses of the glasses in proper position: with respect to the eyes.

Ordinarily the requisito pressure for re- 'taining en eyeglass-treme to pince upon the nose el` the wearer is attained by ineens of' e how-spring connected at its respective extremities with the lenses and adapted to not upon the nose ot' the wearer through the instrumentality of nose-guards connected, respectively, with the lenstrninc. inasmuch as the size of the nose and eyes ztnd tl-so the location of these organs with respect to each other are not uniform in persons it has hither to been customary to connect the respective pnrts of eyeglass-frames together in such man ner ihn-t the freine could be more or less por.-

' fectly accommodated to dilerent persons.

This result, generally speaking, hns been nttempted hy the employment of two seperate edjustnientsjone relating to the how-springand the other to the nose-gnnrds. For the snke of perspcnity these two adjustments will he consideredseparately, although it must be borne in mind that they co-opcrnte in prectice for the production of n common resultnamely, that of permitting` of the accommodation of the frame to difierent persons. in spectacles it hns been customnry to provide n mnllenole nose-bridge disposed ohliquely with respect to the plane of the lenses in order to fit nnd rest upon the nose of theweerer and provided at its respective extremities with arms. These arms were either integrally connected with lthe lens-hows, so that the freine could be adjusted by bending the arms, or were adapted to work in slots ranging 1n the'plane of the lenses and to be clamped toA place therein, so that the lenses could be ndjusted upward or downward in their own` plane. In the first-instance the nosepiece was necessarily constructed of mslleeilolo` ymerel, eind therefore could not he applied to extending spring-how constructed to tit and rest upon the nose of the wearer. However, the contact of this springfnow with the nose of the wearer greatly impaired Vthe efficiency of the springns n ineens for retaining the glasses to place and also caused pressure to he exerted npon the nose by ineens of the howwpringr instead of by ineens of the nosegunrds, thns causing discomfort and injury to the shin oi the nose.

in eyeglass frames inedjustnble nosegunrds having; erms integral 'therewith here been used and vnrions menos have been em ployed for pern'iitting of certain adjustments of the noseguerds, 'Such adjustments have been of two general typos: first, those in which the nose-guards were afforded n range ot rotary motion about zi xcd pivot, and hence were incapable of rectiliner movement 'es o whole, either toward or sway from the pinne of the lenses, and, second, those in which the nosegunrds were permitted n ronge of recti linear or rotary movement'in the'plnne of the lenses.

In en eyeglass-freine embodying tentures of my invention use is made, first, of n resilient bow-spring disposed ohliqnely with reference to the plone of the lenses sind having the respective extremities thereof curved inward and extended forward through the troll of the how to form erins rnngingsnhstantinlly perpendicular to the piene ot the lenses andA ndnpted for rigid attachment to the lens hows or posts; second, of nose-guards connected with the llens howsor posts by means of slottod connections adapted to afford'the guards a range of rectilinear movement in a direction perpendicular to the plane of the lenses and without involving any rotary movement of the guards or of their supporting arms, and, third, of a nose-guard and a separate support* ing-arm connected together by av pivot and provided with a segmental slot and set-screw, the construction beingA such that the noseguard is afforded a range of rotary movementwith reference to the arm and may be clamped lto place by thesetscrew.

The principal objects of my present invention are, first, to provide a light, neat, and durable eyeglass-frame which 4may be confveniently Aand accurately adjusted in all the directions that are requisite for accommodating it.t to different persons and which in use remains firmly in positionl upon the noseof the .wearer without exerting undue pressure -thereong second, to increase the efficiency and shift them out of range of the eyelashes and without otherwise changing the position of the lenses; fourth, to permit of the bending or spreading of they nose-guard arms to adjust the glasses to noses of diiferent widths without injuring the nose-pads, and, `fifth, to adord the nose-guards a range of rotary motion for permitting of the adjustmentthereof to any pecnliarity in the formation of the nose of the user and to provide moans for preventing accidental rotation of the nose-l guards after they have heen adjusted My present invention consists of the improvements hereinafter' fully described, and pointed ont' in the clainns.l

The nature and characteristic features of my present invention will he more fully nnyderstood from the following description, taken in connection with the accompanying drawings, forming part hereof, and in which-- Figure l is a perspective View of an eyeglass-frame embodying features of my invention. Figs. 2 and 3 are respectively an ole- Vation and a plan of my improved bow-sprin g, showing the extremities thereof curved in- Award and forward through the arch of the bow-spring and perforated to form attachingarms. Fig. '4 is an elevation of a nose-guard arm, showing the same slightly inclined at the conter thereof and provided at one of its extremities with straight parallel edges and with a slot ranging longitudinal-ly of the arm and at lthe other of its extremities with a socket and with a segmental slot concentric with the socket. Fig. 5 is a rear elevation of a nose-guard, showing a pivot and set-screw for engaging, respectively, the socket and segmental'slot of the nose-guard-supporting arm illustratedfinFig. 4. Fig. 6 is ancdge ecosse y 'view of the nose-guard, provided with a pad for engaging the noseof the wearer. Fig? is an elevation of a coupling-post adapted for attachment to the lenses -or to the lens-bows and provided with ways for the reception of one of the extremities of the bow-spring and of one of the nose-guard arms also showing abindingfscre-w for claims` ing the last-mentioned members to place. Fig. S is a detail view illustrating the means for permitting of the rectilinear adjustment of the nose-guards in a direction perpendicular to the plane of the lenses. Fig. 9 is a dctail view showing the nose-guard rotatably connected with the nose-guard-supporting arm by means of a pivot and a set -screw working in a segmental slot; and Fi". -l0 isa perspective View showing 'the nose-guards removed in order to permit of the adjust ment by bending the nose-guard arms toward or away from each other,v l

The bow-spring l), Figs. S3 and 3, is constructed ci. malleable or soft metal and is disposed o biiqueiy, Fig. 2, with reference to the planeet the lenses (indicated by the dotted lineyly.) bow-spring are curved inward, as ati-o2, Figs. 2 and 3and extend forward through the arch of the'how, Fig. 2, to forni arms h3, ranging substantially perpendicularl to the plane of showing the same f The respective extremities o 'of the the lenses. Each of the arms o3 is provided with an aperture b", oy means of which it may .be connected to the other parts of the frame.

(lne-errtremital portion of the nose-guard arm ci, Fig. li, is provided with straight. parallel edges d and with an oblong slot (Z2, ranging longitudinally of the arm. The other extrelnital portion of the armc is provided with an aperture or socket d3 and with a segmental slot d". Moreoventhe respective extremities of the nose-guard arm are inclined with respect to each other in order to cause the nose-guarl to Contact with the' lower portions of the bridge of the nose of the wearer. The rear surface of the nose-guardo is provided with a pivot c and a set-screw c2, andv the other face of the nose-guard is provided with a nose-pad c3, of cork, Celluloid, or other suitable material, and in order that certain fea tures of my invention may be fully underl stood it may be remarked that most of the materials that are adapted to this purpose are either fragile, like Celluloid, or easily aliraded, like cork.

The poste, Fig. 7, is provided with ways e', adapted for the receptionof one of tho arms b3 of the bow-spring b and of the longitudinally-slotted extremity of .the nose-guard-sup- EIC porting arm c7. and ranging at right angles with respect to the plane of tlielenses, as

orifice in the posts afer purposes to be preswhereupon the set-screw c2 is screwed to place Athen fitted into-the ways e and the longiscrews e2 are inserted through the slots d2 and to escape the eyebrows and forehead of the greater comfort is-obtained than has been ently described.

' The hcreinbefore-described detaii parts are coupled together in the following manner to constitute an eyeglass-frame embodying my improvements: The posts e are riveted to the retaining-rims that surround the lenses a and a', or, if preferred, to the lenses themselves, care ,being exercised to canse the ways-e. to ran-ge at right angles with the plane of the lenses. The arms b's of the spring-bow b are tudinally-slotted extremities of the nosetruard arms d are superposed upon the arms b3, whereupon the shauks ofthe binding*- tlie apertures b4 and screwed into the posts e. c The .lips or side walls of the lways e` not only serve to prevent accidental rotation of the lenses with respect to the `lidar-spring", but also serve a purpose to be presentlydescribed. The-pivot c of .the nose-guard is then insert'- cd into the socket@S of the supporting-arm d,

in the nose-guardwith its shank in eng-agement with the segmental slot d4.

In the use of my improved eyeglass-frame the peculiar form and disposition ofthe bow or saddle-shaped spring b are productive of the following very important advantages and results: First, the bends b2 serve to increase the resiliency and efficiency of the bow-spring, and thus cause the frame to grip the. nose with a firm yet vsufficiently-yielding; pressure; second, the inclination of the bow-spring to the plane of the lenses permits the former wearer without contacting; with the bridge ot' the nose, whereby accidentalxremoval of the glasses due to changes of facial expression of the user is avoided; third, the shape or general construction o f the bog):-l springs, as illustrated inthe drawings, en-v ables the optician to readilyadj ust the glasses to the proper plane of vision; fourth,` such type of bow-spring affords A'ready means for' increasing` or decreasing the tension of the same on the nose of the person, so that far` possible in the use of bow-springs of the type heretofore employed in connection with eyeglasses, and, fifth, the saddle-shaped spring I) is much more sightly and far less conspicuous on the nose, which is a desideratum with many wearing' or using eyeglasses.

lt frequently happens that eyeglasses rcquire adjustment in order to accommodate them to different persons. )ly improved eyeglass-frame is susceptible of the following three independent adjustments: First, the nose-guards may be adjusted toward or away from each other, in order to accommodate noses of different widths, by bending the supporting-arms' d toward or away 4from each other. This operation would of course be performed by means of pliers or other simi-` -means of the set-screw c2 ot position.

ment of the arms.'

'lar instruments. However, the application of the jaws of-,the pliers or` other similar instruments to the pads c3 of the nose-guards,

would tend to injure the pads. However, in my invention the nose -be detached from the arms d, as shown 1n Fig. 10, by the removal ofv the set-screws c2,

whereupon the arms d may be seized by the jaws of the pliers and` bent toward or 'away from each other until the required adjustment has been attained. -The nose-guards c are then secured to place upon the arms dby and pivots c. Second, the nose-guards may be separately rotated with reference to thearms d., Fig. 9, in order to accommodate them to any peculiar formation efthe bridge of the noose, by loosening the set-screw c2 and rotating the noseguard about the pivot c until, the required adjustment has been attained, whereupon the ,nose-guard is clamped to place by means of 'the set-screw c2. .is normally supported at two points-1. e.,by the pivot c and vons that it cannot be accident-ally shifted out Third, thelenses a and af may inasmuch as the nose-guard be independently shifted in a direction perpendicular to the plane thereof and to the normal line-of visionin order to place them out of range of the eyelashes of the user, Fig. 8, by loosening the binding-screws e2 and' then shifting the arms d either backwardor forward, as required. During this operation the lips or side walls of the ways e engage the parallel edges d of the arms d and insure the movement thereof in a direction at right angles with the plane of the lenses, and the slots d? serve to limit the range of move- After the required adjustment has been attained the arms d may be clamped to place by means of the setscrews e2. v

It will be obvious to thosev skilled in the 'art to which my invention appertainsthat some of the hereinbefore-described improvements may be employed separately in cionneeton with certain well-known types of eyeglass trames and that modifications may bc made in details without departing` from the true spirit of the invention. .Hence l do 'not guards or pads may Y IOC' limit myself to the exact construction hercinbefore set forth; but,
