The present invention has forits principal object to provide a simply-constructed lens mounting of the general character and con? struction hereinafter more fully set fortln] in which the parts have been reduced to a minimum, the device being easily appliedito lenses ofvarying thickness, without chang- 'ing or. disturbing the parts of, the mounting i isia central sectional representationof the parts llustrated in said Fig. 1,'showing thei lens' firmlyfmounted and supported by the stud; "Fig; 3 is a similar sectional Patented No v 3,1914; I

Pteferringnow to the figures of theidraw ings," the reference-character "1 indicates the usual lens provided near its marginal edgeportion and upon the major {axis of the lens j vit hfa post-receiving hole 2. Arranged vin screwed ajscrew-threaded nut-like member this'hole is a post 3 which is formed with a screwthreaded portion 4: projecting beyond the surface 5 of 'the lens' and upon :whichis connected with' the portion? 015 said post '3, and-integrally united-therewith, is a suitably shaped fiattenedfiout member 8,

forming a pivot-plate extending substan tiallynina plane atfa right angle totheiaxis foffs aid post 3; This pivot-plate is slightly angularly'bent, as at-'9, see Figs.= 2and13 of the drawings, so'aslto extend slightlyaway from'the surfacelO of the lens, said'iangular portion being alsofprovided Jnear its free end-portion ll lwith asuitably formed hookreceiving perforation or hole, as 12, for the purposes to be presently more fully described, When the post 3 is inserted in the hole orperforation 2 in the lens, the pivotplate and said post are rigidly fixed in posi tionfby screwing thenut-likemember 6 down upon the screw threaded portion 4 of the post 3 andupon the surface 5 of lens, as shown in saidFigs. 2 and 3.

The combined. pivot-plate and post are preferably made a single pieceof wire of the proper. gage, the part 8, being bent at the proper angle to; the part formingfthe post 3, and being suitably flattenedout in a The reference-character 13, in Figs. 1 to 7 inclusive, indicates a stud with which are integrally connected the arcshap'ed strap members or elements 14 which are adapted to be fitted upon and engage the adjacent edge of the lens. The stud is also: further provided with the flanges 15 between which are arranged in the usual manner, the endportions of the nose-bridge 1G and the noseguards 17, the said end-portions being suitably secured in position by means of a screw 15 18, or any other suitable fastening means. Extending from the lower edge-portion of the inner flat surface 19 of the stud 13, is a suitably formed hook or lug, as 20, adapted to beinserted in the perforation or hole 12,

2o hereinabove mentioned. and in alinement from the upper edge-portion of said flat surface 19 is a forwardly extending holding plate-like member or element, as .21, adapted, to bearranged upon the flat surface 5 of the lens, and haying its front end-portion preferably made much thinner than the 'remaining portion of said plate-like member or element 21, said thin end-portion being so pronged or bifurcated, as at 22, all being adapted to be arranged above the, element 4 ofthe post 3 and embracing that portion of the post 3 above said element 6, in the manner clearly represented said Fig. 2 of the drawings. Suitably secured upon the upper 'surface of saidplate-likeme1iiber or element 1 p 2.1, bymeans of a pin, rivet, orscrew, as 23, or by means of any other suitable fastening means, is a holding catch 24:, made in the 40 form of -a resilient spring-plate'or finger, the free end-portion of which, when the hook or lug Q'Ohas been insertedin the hole l9. and is pivotally moved in the directionj of the arrow y, see.Fi'g.- 3, passes over the free end-portion of the post 3', whereby a hole 'orlperforation 25 in said resilient spring-plate or catch 24 is" brought directly.

over the end of the said post, sothat the said post enters the hole or perforation 25 ;:and,

with the said spring-plate or catch 24 snap; ping into holding engagement with the post 3,. it will be clearly evidentthat' the stud 13 and lens 1 will be securely connected with relation to each other, but may beyjust as readily separated when the spring-plate or catch 24: is raised into the dotted position indicated in said Fig. 2, and whereby the stud can be swung into the position shown in Fig. 3 of the drawings, and readily separated from its holding engagement with. the flat plate 8, so thatthe lens and stud will be brought into their separated relation, aswill be clearly understood from an inspection of said Fig. 3. To prevent the hook or lug 20 p from entering too far into the hole or perfora-tion 12, and thereby perhaps interfering with the pivotal movements of the parts, the hook-element or"lug 20 is preferably made with a pair of ofi-sets or shoulders as 26, which cooperate with the part 11 of the fiat plate 9,- as will be clearly evident.

The operation of the device or mechanism in bringing the stud and lens into their snapped engaged relation, and the manner of separating the stud and lens will be fully understood from the foregoing description, and from an inspection of the severalfigures of the drawings, andneed not, for that reason, be furtherdescribed.

Instead of making the combined pivot- 0 plate and post 3 from wire, in the manner herein-above stated, itmay be made from a flat piece of sheet-metal of the general configuration represented in Fig. 8 of the drawings, the same comprising the pivot-plate with said hook or lug 9.0 and extending part 27 with which is connected, by means of a narrow neck-portion 28, an extension, as 29. Thisextension is bent, at saidneckportion28, at an angle to the plane of the part 27, and theextension is curled in a manher so as to form a tubular post, as 30, see

Fig.9, which is also provided with a screwthreaded portion for the previously men tioned nut-like element. The construction and operation of the remaining parts ofthe eye-glass mounting,-as will be seen from an inspection of saidFig. 8, is the same as that described in connection with the construc- .struction of the said parts, comprising my novel eye-glass mounting, without departing from the scope ofthe invention as described in the foregoing specification, and

as set forth in the appended claims. Hence, I do-not limit my invention'to the exact arrangements and combinations of the several devices and parts, as described in the said specification, nor do I confine myself to the exact details of the construction of the said parts as illustrated in the accompanying drawings.

' .I claimP- a -1. In eye-glasses, combination with a lens,a combined pivot-plate and post made from single piece, said plate being located upon one sideof the lens, and the post extending through the lens, and means upon said post for rigidly securing the combined pivot plate and post to. said lens. v 2. Ineye-glas'ses, in combination with a lens, a combined pivot-plate and post made from a single piece, said plate being located 7 upon one side" of the lens, and said post having a screw-threaded portion extending i said screw-threaded portion of the lens for.
