OPHTHALMIC MOUNTING.
\ Application filed February a construction that will do away with what.
is known as a drop temple, that is a temple which works loosely on the lens frame. Another object of the invention is to provide a construction which will give the temple securing screw a longer bearing in the end piece. Still another object of the invention is to provide. a construction which will make it possible to take up for wear of the temple on the bearing of the end piece.
To these and other ends, the invention consists of certain parts and combinations of parts, all of which will be hereinafter set forth: the novel features being pointed out in the appended claims.
In the drawings:
Fig. 1 is a plan View ofan ophthalmic mounting,constructed. in accordance with this invention;
Fig. 2 is an enlarged view showing the end pieces before the bearing sleeve is secured thereto;
Fig. 3 is a similar view showing the bearing sleeve in position;
Fig. 4 is a sectional view showing the end pieces secured together with the temple mounted to turn on the end pieces; and
Fig. 5 is a perspective view of the bearing sleeve. 7
Referring more particularly to the illustrated embodiment of the invention, 1 indicates the lens rings connected by a bridge 2 and each being split and having two end pieces 3 and 4 secured thereto adjacent the split. These end pieces have two abutting faces 5 held in engagement with each other by a screw fastener 6 which extends through an opening in the end piece 3 and is anchored in the end piece 4: by engaging the screw threaded walls of an opening 7 in the end piece 4. The end piece 3 has a countersunk portion 8 which receives the enlarged end 9 of the screw fastener 6.
The two end pieces have formed between them a recess for the reception of the ear or terminal 10 of the temple 11. In this instance, the recess is formed by recessing both portions as at 12. Secured to one of the 10, 1926. Serial No. 87,206.
end pieces is a tubular or post piece 13 which lies in an opening in the piece 4 in drive fit or soldered connection with the walls of said opening. member bridges the recess formed by, the recessed portions 12 and extends into an opening formed in the end piece 3. This opening has a cylindrically formed portion 14. which fits the outer surface of the post and a flaring portion 15. The postlS has the temple ear 10 turning thereon and its.
length is such that when it'fits into the cylindrical portion let it does not extend to the inner end of the cylindrical portion. A fastener having a screw threaded portion 16 is anchored in the post and has a flared head 17 which fits the flared portion 15 of the opening in the end piece 3. Owingto this flared portion of the screw fastener and the flared portion of the wall of the opening of the end piece 3, together with the fact that the post, 13 does not extend to the inner end of the cylindrical portion 14 of the inner end of the end piece 8, it is possible by turning the screw fastener 1617 to produce any desired amount of frictional engagement between the faces of the terminal 10 of the temple and the walls of the recess formed between the end pieces 3 and 4. At the same time the temple ear turns on a cylindrical surface which is fixed and prevents: the temple ear from acting directly on the screw fastener and thereby effecting the loosening of the latter. Furthermore, in assembling the parts it is possible to fit the temple on the post 13 before the two end pieces 3 are secured together, so that by fastening the screw fastener 6 not only the lens is secured in place, but the temple is secured in place and thereafter the desired pressure on the temple between the two end pieces is obtained by fastening the screw fastener 16l7 in position. F urthermore, should either of the screws break the other will hold the parts together.
In ophthalmic mountings it is desirable that the temple should be firmly enough clamped to the end piece that it will require a slight pressure to move it, but it should not be too tight. In practice, the temple very often works loose and it is then known as a drop temple. In this invention, it is more easy to take up for wear caused by the temple working in the end pieces than This tubular or post on the regular type of end piece. The screw which secures the temple is threaded all the way through the tube or post and this gives a much stronger bearing than the ordinary screw. By having two screws in the end pieces it is possible to make the adjustment of the temple more positive and naturally holds the end pieces together more securely than one screw would.
What I claim as my invention and desire to secure by Letters Patent is:
1. An ophthalmic mounting comprising a split lens ring having two end pieces projecting outwardly adjacent the split, the end pieces being formed to provide a temple receiving recess between them, one of said end pieces having an opening intersecting one wall of the temple receiving recess, a tubular temple bearing post internally threaded and rigidly secured to the other end piece, projecting across the recess and detachably fitting in the opening of the other end piece to bridge the recess, a temple mounted to turn on the post, and a screw fastener passed through said opening and engaging the end piece in which the open ing is provided and also extending in and anchored to the post to draw the two walls of the temple receiving recess into engagement with opposite faces of the temple.
2. An ophthalmic mounting comprising a split lens ring having two end. pieces project-ing outwardly adjacent the split, the end pieces being formed to provide a temple receiving recess between them, one of said end pieces having an opening intersecting one wall of the temple receiving recess, a tubular temple bearing post internally threaded and rigidly secured to the other end piece, projecting across the recess and detachably fitting in the opening of the other end piece to bridge the recess, a temple mounted to turn on the post, a screw fastener passed through said'opening and engaging the end piece in which the opening is provided and also extending in and anchored to the post to draw the two walls of the temple receiving recess into engagement with opposite faces of the temple, and a separate screw fastener connecting the end pieces at a point on the inner side of the temple receiving recess.
3. An ophthalmic mounting comprising a split lens receiving ring having two end pieces projecting therefrom adjacent the split, said end pieces having temple receiving recesses formed between them, a temple bearing post rigidly secured to one of the end pieces and having a bore, the walls of which are screw threaded, the other end piece having an opening formed with a cylindrical portion receiving the post and an enlarged portion at the outer end thereof, the post entirely bridging the recess, a temple mounted to tum on the post, and a screw fastener anchored in the post and having a head cooperating with the hollow wall of the enlarged portion of the opening to draw the two walls of the recess into frictional engagement with the temple.
