EYEGLASSES.

Application filed November 10, 1911.

To all whom it may concern:

Be it known that I, FRIEDRICH PELS-LEUS- DEN, a subject of the German Emperor, residing at Berlin, Germany, have invented certain new and useful Improvements in Eyeglasses, of which the following is a specification.

My invention relates to eyeglasses and has for its object to provide an eyeglass, capable of being easily positioned or removed, which while in position is very securely held and cannot readily tilt or slip and yet which maintains its position without undue pressure and consequent discomfort to the wearer.

A. further object of my invention is to provide an eyeglass as above set forth, in which the parts necessary for suitably positioning the eyeglass upon the wearer shall be conveniently and quickly adjustable so that the same type of eyeglass may be fitted to persons of varying facial characteristics.

Other objects of my invention will appear as the specification proceeds.

In eyeglasses of conventional type a difficulty which has hitherto been met with is that the eyeglasses usually ride or pivot upon the ridge of the nose and can only be held in place by considerable pressure of the springs connected with the nose clamps or clamping plates while in the case of persons having flat, broad and lean noses it is almost impossible to satisfactorily hold the eyeglasses in place with any reasonable pressure. The tendency is, therefore, for the glasses to tilt forward upon the nose, so that they rest at an angle with the optical axis of the eye, and to slip so as to displace the lens centers from said axis; this is uncomfortable and furthermore, apt to produce further injury of the eye. If the clamping plates be subjected to a very strong spring pressure with a view to overcoming the tilting and slipping the result is not only immediate and extreme personal discomfort but a resultant muscular and nervous strain apt to produce headache and injury to the eye itself.

I avoid the above disadvantages with my invention since it comprehends an eyeglass which is not clamped upon the nose proper but, rather, is provided with a pair of nose Specification of Letters Patent.

Serial No. 659,502.

clamps each of which extends into and clamps the root of the nose at the inner canthus or corner of the eye where the upper and lower eyelids meet, while a bridge similar to the ordinary spectacle bridge, which unites the glasses centrally and lies considerably below the level of the nose clamps, rests upon the ridge of the nose. This bridge may be bent or bowed to a greater or less degree to conform to the individual nose. In a preferable form the nose clamps are supported upon an upper bridge. I find that this construction, owing partly to the distance between the two points of support (2'. 6. between the bridge and the line of the two nose clamps), and partly to the fact that the line of the two nose clamps lies considerably above the center of gravity of the eyeglasses, will maintain the eyeglasses securely in position without tilting or slipping and with extremely small pressure upon the nose clamps. Clamping plates of much smaller area of contact than are employed in the usual construction, in which the bony part of the nose is gripped, may also be employed with my improved eyeglasses as just described. The u per bridge has great advantages in fixing tie eyeglass in the right position to the optical axis of the eye and in that greater freedom in the attachment and adjustability of the nose clamps is insured and, as there is greater space available than in the usual construction of eyeglasses, all the parts can be made stronger than heretofore, thereby reducing the liability to the damage of the spring parts to which the usual eyeglasses are constantly subjected in putting them on and removing them.

The exact character of my invention will be better understood by reference to the drawings which show the same in a number of its possible modifications; in these views, to save space, parts of the lenses proper are broken away when not required to'disclose the character of the invention.

Here Figures 1, 2 and 3 represent respectively a front elevation, a plan, and a section (along the line 3- 33 of Fig. 1) of a preferred form of my invention; Fig. 4: is an elevation and Fig 5 a section (along the line 5-5 of Fig. 4:), parts being omitted,

showing a form of my invention in which the upper bridge is attached to the feet of the lower bridge and is vertically adjustable relatively thereto; Figs. 6 and 7 are respectively an elevation and a plan of a modified form of my invention, very similar to that of Figs. 4 and 5, in which the upper bridge is elastic and carries linger pieces to manipulate the nose clamps; Figs. 6 and 7 are respectively elevation and plan of a modification of my invention, very similar to that of Figs. 6 and 7 but involving a different mode of attaching the nose clamp structure to the upper bridge; Figs. 8, 9 and 10 are respectively elevation, plan and section (along the line 10-10 of Fig. 8) of a modification of my invention in which the nose clamp structure is adjustable as a whole upon the upper bridge; Figs. 8 and 9 are, respectively, elevation and plan of a form of my invention similar to that of Figs. 8 to 10, except that the nose clamp structure is adapted to be adjusted in a somewhat clifferent way; Fig. 11 is a detail showing a special arrangement of the nose clamp structure when the upper bridge is made of round wire; Figs. 12 and 13 are respectively plan and sectional elevation of a detail showing another arrangement of the nose clamp structure for an upper bridge of round wire; Fig. 14 is a plan showing the arrangement of the nose clamp structure Fig. 11 suited to an upper bridge of round wire; Figs. 15 and 16 are respectively elevation and plan showing another modification of my invention, and Figs. 15 and 16 similar views respectively of a slight variation from this modification; Figs. 17, 18 and 19 are respectively elevation, plan and section (along the line of 1919 of Fig. 17) of another modifica tion of my invention; Figs. 17 and 18 are respectively elevation and plan of still another modification of my invention; Figs. 20 and 21 are respectively elevation and plan of a modification of my invention showing a special form of the upper bridge; Figs. 20 and 21 are respectively, elevation and plan of a modification of my invention similar to that of Figs. 20 and 21, in which a different mode of attaching the upper bridge is employed; Figs. 22 and 23 are, re-

.spectively, elevation and plan showing another modification of my invention; Fig. 24 is a section along the line 2 l24= of Fig. 22, and Fig. 25 is a transverse section along the line 25.25 of Fig. 2 1 both sections being enlarged; Figs. 26 and 27 are respectively, plan and section (along the line 27-27 of Fig. 26) showing another arrangement of the nose clamp structure; Fig. 28 is an elevation showing still another arrangement of the nose clamp structure; Figs. 29 and 80 are respectively, plan and elevation (the latter on. an enlarged scale) of another modiployed within the spirit of my invention.

In the form shown in Figs. 1 to 3, the bridge 2 is bowed outwardly and upwardly and rests upon the ridge of the nose just as does the bridge in the case of the conventional spectacle.

vertically above the bridge a second or up per bridge 6 extends from lens to lens, being attached to the upper end of each lobe 5 and supported upon this upper bridge is a pair of clamp arms 7 carrying upon their inner ends nose clamps 7 and provided at their outer ends with finger pieces 8 by means of which the clamp arms may be opened and the nose clamps separated against the resistance of a double armed spring 9, centrally fastened to said upper bridge. Suitable stops may be used to limit the movement of the clamp arms. The upper bridge 6 should be at such a height above the lower bridge as, when suitably bent or bowed inwardly, to rest against the root of the nose or against the forehead just above the root of the nose. A preferred height is a little below the upper rim of the lens in the case of the ordinary ellipticallens. The clamp arms are so dimensioned that when the glasses are in place with the lower bridge upon the ridge of the nose and the upper bridge against the root of the nose or against the forehead just above the root of the nose, the nose clamps 7" will project into the inner corners or canthi of the eye. By attaching the clamp arms to the lower side of the upper bridge instead of to the upper side the said upper bridge may be raised still higher and farther away from the lower bridge.

In order to adapt the eyeglass to different noses I may provide the lobes 5 with a slotted lug in which the end of the upper bridge is sliclable, a screw 18 being used to hold the bridge fast in the lug when the proper adjustment of said bridge has been determined or I may omit the lug and depend uponbending only of the upper bridge to secure adjustment.

In the modification shown in Figs. 4; and 5, the upper bridge 10 does not attach to the lobes 5, but has each end bent downwardly and slotted at 11 to slip over the foot of the lower bridge 2, so as to rest against the edge of the lobe 5; a vertical adjustment of the upper bridge is thus provided, a screw 15 At a considerable distance being used to clamp the bridge when set at the desired height.

Figs. 6 and 7 show a modified form of my invention in which an upper bridge, comprising a cross bar 19 joined by welding or other suitable means to stem members 12, very similar to the upper bridge of Figs. 4 and 5, is used. Each stem member 12 is however, bent rearwardly, where it joins the cross bar, to constitute a clamp arm 16, which carries the nose clamp 7 The cross bar 19 is elastic and may be bent so as to spread the nose clamps in attaching the eyeglasses to the nose by pressing together the finger pieces 13.

Figs. 6 and 7 show a clamp arm 17, integrally a part of the cross bar 19, this cross bar being joined to the lower bridge by the stem member 14. The bridge may be bent to spread the nose clamps 7 by using the finger pieces 13 as before.

Figs. "8, 9 and 10 show a modified form of my invention in which the nose clamp structure is provided with a slotted base portion 21, arranged to engage the upper bridge and to be adjusted laterally thereupon. The structure is held in any desired adjustment by means of suitable set screws, and twisting is prevented by the overlapping portions of the base.

Figs. 8 and 9 show a form of my invention very similar to that of Figs. 8 to 10, in which the nose clamp structure is adjustable by turning.

Fig. 11 is a detail, showing one mode of attaching the nose clamp structure to the upper bridge where the aforesaid bridge is made of round wire. In this case a tapered sleeve 25, slit longitudinally is fixed upon the bridge 19 by a second sleeve 2a which is pressed on the tapered end of the sleeve 25. Preferably both parts may be provided with a screw thread at their tapering ends. The second sleeve 24:, hollowed out to receive a coiled spring 26, is slotted at one side to receive the clamp arm 7, which is drilled to fit over the bridge. By giving a suitable length to the slot the nose clamp structure is slidable in the length of the bridge against the resistance of the spring 26.

Figs. 12 and 13 show another arrangement of the nose clamp structure applied to a bridge of round wire. Here the clamp arm 7 provided with a spring 28, one end of which attached to a sleeve 2& linearly adjustable upon the bridge wire and adapted to be fixed in any desired position by a set screw 29. The clamp arm is provided with a finger piece 27, and a slot fitting over the bridge wire. The end of the clamp can be made of round wire and bent around the upper bridge to avoid slitting.

lar to that of Fig. 11 as regards linear adjustment of the nose clamp as a whole, but the bridge 19 is itself made elastic so as to permit the nose clamps to be separated by bending the eyeglasses out of their normal plane.

In the arrangement shown in Figs. 15 and 16, the clamping plates or nose clamps are round and quite small. The clamping arms are provided with finger pieces 13 and attached to the stem 22 by the screw 30.

Figs. 15 and 16 show a form substantially the same as that shown in Figs. 15 and 16, except that the clamp arms are not provided with finger pieces and are pivotally fastened to the cross bar 19, instead of to the stem 22. In both forms (Figs. 15, 16, 15 and 16) the nose clamps 7 are themselves pivoted upon the clamp arms 7 and the upper bridge is joined to the lower bridge.

Eyeglasses of my invention may be either finger-piece eyeglasses or, if preferred, both the upper and lower bridge may be made springy, so that they may be readily bent, thus throwing the lenses out of their normal plane and separating the nose clamps; in this construction the finger pieces themselves may be omitted. Figs. 17 to 19 show eyeglasses of this form. The stem 21 of the upper bridge is here attached to the foot of the lower bridge and may be given vertical adjustment; it is held in position by a screw 15.

Figs. 17 and 18 show a form similar to that of Figs. 17 to 19, except that the upper bridge is integrally a part of the lower bridge or secured thereon.

Figs. 20 and 21 show structures in which the nose clamps are roughened plates 23, attached directly to a sharp rearward bend of the upper bridge on each side of its central spring portion. The upper bridge 20, through the stem 21, is attached to the foot of the lower bridge and held by a screw 31. Thereby the stem is vertically and rotatively adjustable.

Figs. 20 and 21 show a structure practically the same as that of Figs 20 and 21, in which the bridge 20 is not attached to the lower bridge but is slidable in the slotted upper part of the lobe 5, a screw 32 being used to hold the bridge fast, whereby a certain amount of lateral sliding adjustment is provided.

Figs. 22 to 25 inclusive show a modification of my invention in which the nose clamp structures are pivotally attached to the upper bridge are provided with finger pieces, and are operated against the resistance of suitable springs. These nose clamp structures are also adjustable toward and away from one another, to provide for different noses. To accomplish these results The arrangement shown in Fig. 14; is simithe upper bridge 19 is a straight, hollow tube, adjustably attached by stems 14 and screws 15 to the lobes 5. Within this tube is a screw 32, the ends of which are oppositely threaded. Each clamp arm 7 passes through a little box, 34, and is there engaged,

with a coiled spring 35, one end of which is attached to said box. Upon the top of the boxis a ring 33, adapted to be slipped up through a slot in the bottom of tube 19 so as to fit within said tube and threaded so as to be engaged by one of the ends of screw 32. An exterior head 36, at the end of the screw, enables the same to be rotated so as to bring the boxes 34, closer together or carry them farther apart.

. Figs. 26 and 27 show another modification of the nose clamp structure. The clamp arms 7 are pivotally fastened to slotted base portions 24 which are held in any desired adjustment on the upper bridge 19 by means of suitable set screws. Arms 39 fixed to the axis 40 of the clamp arms 7 are held in position by a spring 37 which is connected to a face plate 38. Twisting of the base portions 24 is prevented by overlapping portions of the base or by the arms 39 being let into the upper bridge 19.

Fig. 28 shows a modification of my invention in which the upper bridge is entirely omitted, the nose clamps 7 a being supported upon elastic clamp arms 37 which are themselves supported from the feet of the lower bridge. These clamp arms may be adjustable just as is the case with other forms previously described. Finger pieces are employed to spread the nose clamps.

Figs. 29 to 31 show a modification of my invention in which the nose clamps have Here the practically universal adjustment. upper bridge comprises a hollow tube or sleeve 38 adjustably attached to the lobes 5 by stem members 39 and screws 40. The clamp arms 7 carrying the nose clamps 7 pass through a longitudinal slot at the rear of this sleeve and terminate in plates 41 which are slidably fitted within the sleeve and tend to be drawn together by a spiral spring 42. Each plate has fixed to its inner side a spindle 43 which passes loosely through a suitable hole in the other plate and loosely through the head 44 at the end of the sleeve; the spindle 43 terminates outside of the sleeve in a button 45. By pressing together the two buttons 45 the nose clamps 7 may be pressed apart so that the eyeglasses may be positioned upon the nose. Nuts 46 are threaded upon each spindle 43 just inside the head and may be adjusted so as to fix the extent to which the nose clam as may be separated. The sleeve 38 may e axially rotated between the stem members so as to raise or lower the nose clamps 7 and is provided with a face plate. The clips 7 may have any desired shape and position,

and, if preferred, they may grip the nose a pair of lenses connected by a rigid bridge adapted to rest upon the ridge of the nose, an upper bridge adapted to rest near the root of the nose, and clamping devices adapted to grip the root of the nose at the inner canthi supported from said. upper bridge.
