oPH'rHfALMIc, MOUNTING.

Application'led June 13, 1922. Serial No4 567,995. v

To all whom t may concern.:

VBe it known that I, 'WAYNE S. SE'ARLnm a citizen ot 'the United States, residing at Providence, in the county of Providence andA members by which the `temple members are secured to the iframe, and an improved means tor securing one of 'the members of the joint to the end portion of the frame in such a way as to reduce the cost, and render more practical and permanentfthe construction of the mounting.

With these and other objects in View, the

invention consists of certainv novel featuresl of construction, as will be more fully described, and particularly1 pointed out in' the appended claims.

ln the accompanying drawings:

Figure l isa perspective view showing a non-metallic spectacle frame in which my improved temple joint is employed. j

Figure 2 is a sectional edge view of the frame at the joint, showing the arrangement of the ljointspurs also the stop in the joint. j

Figure 3 is a side view of the joint partly in section illustrating the stop` lugs of one of the members of the joint as engaging recessesin the other member of the joint for the purpose of providing a stop in; the joint for limiting its opening motion.

Figure a is a side elevation of the joint showing the arrangementor" the spurs and the arrangement of the stop in the joint.

Figure 5 is a view of the rear of the end piece of the frame showingthe transverse groove across the face thereof whereby the extremityv of the end ypiece may be bent back into the position illustrated in `dotted lines in .Figure 2, to permitlpiercing' and positioning of the joint spurinto the end piece after which this portion'may be bent back to. normal.

Figure .6 is a modification showing the nection with the, temple and, therefore, it

is found .ofl advantage to form these end .pieces straight or` on al line substantially parallel with the plane of the sidefedg'es of the lens frames `so thatthe whole .may

be cutfrom a sheet of' stock to remain or operate in. their normal'plane. It isalso found of advantage to set `the spur of one of the hinge members intol itsend piece 'so thatits axis vwi'l'l be substantially parallel with the plane of the si'deedgesont the lens'frame, Vand also to provide afstop in the jjoint within the circumferenceof the body portion thereof to limit theopening swing of' the/temple member; and the following is Aa .detailed description of means by which 'these results may be accomplished:-

With reference to the drawings, 10 desvignatesth'e usual spectacle frame whichis formed who'lly 'or' in partof non-metallic material such `for instance as Celluloid, Zylonite or other Vsuitable material and vvon the opposite extremities of this vframe .are formed .end pieces 11 integral therewith.

It is found'of advantage to form the end pieces straight,' instead 'of curving them 'back beyond 'the plane of the vside edges 'of the frame for several reasons: first, the end piecey remains permanently 'in its, normal plane yas ,cutfrom' sheet stock; second, the temple" member in swinging inwardly willv lay jtl'at against the inner` edges of the f frame to take upthe miniinumlspacewhen folded; andnthirchthe spur oitthelhinge may *be more vreadil 'positioned lin the end :p'ie'ce as presently c escrib'ed.

Myj'special 'construction of joint is preferably formed vof two members, one 'having a Vprong or spur/,13 tot s et intofthetemp'lem.

as shown in dotted lines in Figure 2, While the other has a prong spur ll arranged to set intofthe endpiece l1, which latter is preferably 'offset bodily inwardly from the inner tace of the endpiece 11 and its axis is lpreferably set so that ywhen positioned therein it will be substantially in line with the plane oi" the inner face oi the end piece, and to facilitate the connecting or" this joint member to the. end piece and also to facilitate the setting oit. the spur thereinto, I preferably form a transverse groove 16 across the rear tace or" the end piece as best shown in Figure 5, into which groove is set Athe body portion 17 of the hinge, whereby when heated the portion 18 of the end piece Vmay' [back into its normal shape Where it will be lushivith the outer edge of the temple.

In some instances-instead of .setting the spur ,Qna line parallel With the side edges of the lens frame, `I kmay set the spur on an angle as illustratedin Figure 6, throughthe end piece and secure the same therein'.

by 'means of a pin 19.

It is found in practice to be of advantage in theconstruction of hinges of this character to provide a stopin the hinge to limit the opening` swine' of' the temple, and to do this in a simple and practical Way I havel recessed `at 91l the members 20 ot the body portion of the joint 17, and I have pro-- vided the inner member 220i the joint with a pair of transverse lugs 23l adapted to swing in the recesses 21 in the opposite mem ber and to bring up against lthe end Walls 24 of these recesses thereby limiting the opening swing of the temple and in thisconstructionthe stop is formed entirely Within the circle of the periphery of the body of the jointA thus forming a strong and durable stop Without taking up extra room in the joint.

with a stop lug 25 on the back portion of the body of the middle memiber, which is arranged to engage the hack portion 26 oil the forkedmember of the hinge at a point between its branchesto limitthe opening motion of the hinge.

My improved construction of end piece and joint membei connected thereto, forms a practicalconstruction .which is strong and vdurable and efiicient in its. action.

The foregoing description is directed solely towards the construction illustrated, but I desire it tobe understood that I reserve the privilege of resorting to all the mechanical changes to which the device is susceptible, `the r,invention being defined and limited only by'tlie'terms of theappended claims.

Another construction is to provide a hinge lend piece in a line substantially parallel 4with the, plane'` of said frame edges, and

means engagingy the spur to lock it in the end piece.

2. An ophthalmic mounting comprising a non-metallic frame having an. end` piece with its rear 'tace disposed in a plane substantially' parallel With that ot the side edges of the frame, a temple, a hinge for connecting the temple to said end piece, one member of said hinge having a spur set into said end piece, and the body portion or said hinge member being provided with a. stop for limiting the opening swing ofthe temple. i j j 3. An ophthalmic mounting comprising a non-metallic trame having an end piece with its rear face disposed in `a plane substantial? ly parallel'ivitli that of the sideedges `of the frame', a temple, a hinge for connecting the temple to said end piece, one member of said hinge having a spur set into said end. piece7 and a stop formed in said hinge With-l in' the circumference of its body portion for vlimiting the opening swing of the temple.

6. An ophthalmic mounting comprising a non-metallic 'frame having an end piece, saidv ly parallel with that of the side edges ,ot

the frame the end piecehaving a portion `adjustable from a plane substantially at right angles to the side edges of the vtraine to facilitate positioning of a spur, the ad-y justable member forming an abutment or stop for the temple.

`.In testim on'vvjvhereof I affix my signature.
