This invention relates to spectacles and I has for its object to provide an article of such class, in a manner as hereinafter set forth, with means for not only reducing the ohstructed field of vision to a minimum, but also to prevent the nose bridge of the spectacles from riding downwardly on the nose to maintain the lenses in the position to which they have been. initially set.
I. In spectacles now in general use, the temporal attachment is connected 180' meridian of the lenses and these latter at ri ht angles with respect to the attachment; 0 positions of the attachment and lenses relative to each other not only have been an obstrucs tion to lateral vision, but further the nose brid e would shift downwardly on the nose to c ange the (positions of the lenses after initially set, an to overcome such ObJGCtlOHS is the primary objectof the invention, and
' to this end the invention consists in the elevoting, of the point of connection of the attachment with the lens frame or lenses, so
that the temporal attachment'is removed from a direct useful field of vision, thereby permitting ofa clear and unobstructed view of objects, which when otherwise obstructed, have a direct tendency to endanger human lives, and the invention furtherconsists in positioning the lens frame or lenses .at an obtuse angle with respect to the forward ends of the tem oral attachment, whereby the lens frame or enses will act to prevent the nose bridge from riding downwardly on the nose,
under such conditions maintaining the lenses parts,"as hereinafter more speci cally described and illustrated in the accompanying.
drawings, wherein is shown an embodiment of the invention, but it isyto be understood that changes, variations and modifications can of the claims hereunto appended.

Figure 6 a front elevation of a further modi ed form.
Referrin to Figures 1 to 3 of the drawings, the front 0 the spectacles consists of a heavy shell frame 1 formed of zylonite, fiberloid or other suitable material capable of resiliency and stretching under the application of heat.
The frame 1 includes a nose bri 2 and a a pair of lens receiving rims'3. e nose bridge 2 is arranged between the op osed inner-sides'of and'connects the pair ofrims. 3together. A lens 4 is mounted in each of the I'HIIS 3. I
The outer'side of each rim is termed the temple side and integral with such temple side is a protuberance 5 which has its inner end lique to the center of the horizontal meridian of the lens 4. The protuberances 5 on the temple sides of the rims are located above the spectacles are in place on the face. As illustrated, by way of example,- each protuber- I ance 'isarranged at the upper part of the temple side of the rim and disposed substantially tangentially with-respect to the latter. The rotuberances 5 arelocated out of the usefu field of vision and are termed end pieces, end piececonnections or oints of attachment for'the temple bars to epresently referred to and act as a means to maintain the temple bars out ofthe useful field of vision when the spectacles are worn. The angles included between the end piece connections and the plane of the lenses are acute. That part of the temple side of each rim from the protuberance tothe bottom of such side it. 5 by the hold-fast devices 14 and to the temple is formed in a mannerto prevent the impairing of the vision from the temple side of each rim from the protuberance to the bottom of such side is formed in a manner to prevent the impairing of the visionfr om the temple sides of-the spectacles. The: outer end of each end piece 5 is bevelled as at 6,
and is adapted to abut againstthe bevelled end surface 7 of the temple bar 8. The
temple bars 8 are connected to'the end pieces 5 by hinges 9. The axes of the hinges9 are inclined with respect to the-plane of the lenses. The bevelled end surfaces 6 and 7 extend throughout rearwardly at an inclination from the top thereof. The bevelled surfaces 6 are adapted to abut the bevelled surfaces 7. when the spectacles are worn whereby the frame 1 will be disposed at an acute angle'with respect to the forward ends of the bars 8, as clearly shown in FigureB, and this inanner of p0sitioning the frame 1 with respect to the bars 8 will prevent the nose bridge from riding downwardly 0n the nose so that the initial 'Each of-the templeb'a'r's 8 comprises an upper portion 10, a-dep'ending rearwardly. extending intermediate portion 11,. and a downwardly inclined rear portion 12. The
position of the lenses with respect to the eyes will be maintained.
upper portion 10 is of greater length than "either of the portions 11 and 12 and is. slightly curved in the direction of its len 'th'so that it will extend, intermediate its ends, towards the head ofzthe wearer.
It will be stated, however, that the temple bar can be set up of any suitable contour.
" The frame is applicable to receiveany size "'or'shape of lenses, as the-material of the- 1 frame can be readily stretched to receive the lenses-4:. The act of stretching will in no manner distort or move out of alignment the end pieces 5. It willbe noted that the end pieces 5 are always symmetrical as they are I based on straight lines instead of circles.
' The bevel faces on the opposedends of an The hinges 9 are secured .to the end pieces bars 8 by the hold-fast devices 15.
Referring to Figure 5, the angles formed by the bevel on the end piece 5 are shown in full lines and designated A, B. The angles formed by the bevel on the temple bar 8 are shown in full lines and designated C, D.
end piece andtemple bar are indicated-in dotted lines and designated E. The bevel on the temple bar is indicated in; dotted lines and designated E. The bevel on the temple bar 8 extends rearwardly at an inclination from the top thereof and the-bevel on the end-piece projects outwardly at an inclination from the-- top thereof. The bevelsalso extend trans versely of the end piece and temple bar. In
Figure 5,1t-he upper face of the end piece is indicated at H and thefront side face at I. The upper face of the temple bar is designated J and the outer side face thereof at K. The hinge connection is designated 9.
Referring to Figure 4, the front of the spectacles is formed from a frame constructed of light shell material and which includes a pair of rims 16, 17, connected together by a nose piece 18. Secured to each of the rims, at the top thereof, is a laterally extending tangentially disposed end piece comprising an inner clamping portion 19 and an outwardly extending short protuberance 20 disposed tangentially with respect to the rim. .The end piece ,or point of attachment, shown 1nFigL 1re 4, and which is referred to generally by the reference character 21, is
symmetrical and based on straight lines instead of circles. Pivotally connected, as at 22, to the outer end of the arm 20, is a temple bar 23, and the point of connection between the arms 20 and bars 23 is such as to maintain the lenses at an acute angle with respect to the temple bars. Each rim canbe stretched for any requirement, to conform to the shape of the lens 24.
Referring to Figure 6 of the drawings, it illustrates a. pair of rimless spectacles complete, and the lenses thereof are indicated at '25, and each of which is shown, by way of example, as of polygonal contour. The lenses 25 are coupled together by a nose bridge 26. Connected to each lens 25, at the top thereof, aswell as extending laterally there- ;from is a tangentially disposed end piece or point of attachment 27. Holdfast devices 28 are employedfor securing the inner end of the end piece 27 to the lens 25, and" the outer end ofthe end piece 27 is pivotally connected, as at 29, to a temple bar 3(l'and the connections between the end pieces 7 and temple bars 30 are such as to provide for the lenses to be disposed at an obtuse angle with respect,
to the forward end .of the temple bars 30. Bearing strips 31 are interposed between the end pieces 27 and the edges of the lenses 25, and bearing strips 32 are interposed between the nose bridge and. the lenses 25. The bridge 26is secured to the lenses 25 by the holdfast devices 33,.
It will appear by reference to Figures 4 and 6 that the end pieces 21, 27 each include a horizontal part anda part divergent from the latter. The divergent part is for connection in fixed relation with respect to the lens the temple is for pivotal connection to the horizontal part.
The inner end of each protuberance, end piece or point of attachment, of thevarious forms shown, is disposed at a meridian at an oblique angle to the horizontal with respect toja lens, that is to say the protuberance or -end piece or point of attachment of the/tempic is locatedabove the center of the pupil of the eye when the spectacle is in place before the eye. This arrangement permanently maintains the lenses in a predetermined fixed position, as well as prevents any tilting thereof and further acts to arrest the moving foryvard of lenses with less tensionon .ed by the use of an end piece or point of attachment, in accordance with this invention.
The end piece or point of attachment permits of greater range of adjustments, due to the fact that the temple is on a horizontal plane with the brow and top of the car as the dimension of the head is more uniform at the position of the end piece or point of attachment than where the temple runs over the cheek bones as is usually the case in the form of spectacles now used. The end piece or point of attachment, in accordance with this invention will in addition permit of a greater number of people being fitted and benefitted by glasses who heretofore, due to irregular facial contour, could not be supplied. Furthermore, the position of the end piece or point of attachment with respect to the lenses elevates the temporal attachment above the" position now generally employed, which is at the 180th meridian of the lenses, and by elevating the end piece or point of attachment, it is removed from a direct useful field of vision, thereby permitting of a clear, unobstructed view of objects. The setting up of the spectacles with the end piece or point of attachment, in accordance with this inven-- tion, necessitates no noticeable increase in the cost of manufacture, thereby not limiting its usages or advantagesto any one, at the same time it possesses more attractive and useful advantages.
As hereinbefore stated,'the positioning of the frame or the lenses at an acute angle with respect to the temple bars prevents the nose bridge from riding downwardly on the nose,
under such conditions maintaining the lenses in the position in which they have been in- .itiall y set to obtain proper vision at all times,
It is to be understood that in referring to the horizontal meridian or median line or the horizontal center of a lens, I am referring to the pupilary center thereof, that is, that point of a lens, regardless of the peripheral configuration of the lens, that is on a straight line with the center of the pupil" of the eye of the wearer when the eye is directed forwardly on a straight line and when the spectacle carryingthe lenses are in proper position before the eyes of the wearer. This is intended to distinguish clearly from What otherwise might be referred to as the geometrical center of a lens; the geometrical center being unimportant in the matter of determining the proper position of the lenses of a pair of spectacles before the eyes of the wearer. y s a It is thought the many advantages derived from a pair of spectacles, constructed in. accordance with this invention, can be readily understood, and-although the preferred embodiments of the invention are as illustrated and described, yet it is to be understood that changes in; the details of construction can be had which will fall within the scopeof the invention as claimed. i
