OBHTBAIMIC MOUNTINGv Filed NOV. 10, 1927' buyer), or- Georyefif Da,
Patented Mar. 18, 1930 UNITED STATES GEORGE E. DAY, OF ROCHESTER, NEW YORK, ASSIGNOR TO BAUSGH & LOMB OPTICAL PATENT OFFICE COMPANY, OF ROCHESTER, NEW YORK, A CORPORATION OF NEW YORK OPHTHALMIC MOUNTING Application filed November 10, 1927.
The present invention relates to ophthalmic mountings, and more particularly to mountings of the sliding-bar-bridge type, and its objects are to simplify and improve ophthalmic mountings of this character, to the ends that the lens-holding rims shall hold firmly and with a uniform clamping action against the bar bridge, and that shall be capable of very wide ranges of adjustment, so
that a single mounting shall be adjustable, Within reason, to the facial characteristics of any wearer, and shall hold firmly and uniformly in any position of adjustment.
The invention will be more fully described in connection with the accompanying drawings, in which Fig. 1 is a rear elevation of an ophthalmic mounting constructed in accordance with a preferred embodiment of the present invention; Fig. 2 is a section taken upon the line 22 of Fig. 1, looking in the direction of the arrows; Figs. 3 and 5 are fragmentary rear elevations of the respective lens-holding rims with projections attached; and Fig. 4 is a perspective view of a preferred bridge-bar slotted tube adapted to receive the projections shown in Figs. 3 and 5.
Ophthalmic mountings usually comprise two lens-holding members 2 and 4. In mountings of the spectacle type, the temples 6 are provided. The invention is, however,
from some points of view, equally applicable to other mountings than spectacles. The lens-holding members 2 and 4 are shown as rims, but the invention may be embodied in mountings of the rimless type also, in
which event the rims 2 and 4 will be replaced by lens-holding clamps, as will be understood by persons skilled in the art. The rims are each provided with a projection 8 and a guard arm 10, which, in the case of rimless mountings, may be carried by the lens-holding clamps.
According to the preferred embodiment of the invention that is illustrated in the accompanying drawings, the projections 8 extend into a longitudinally slotted tube through opposite ends 12 of the tube. The sides 14 and 15 of the tube, on opposite sides of the longitudinal slot 17, are pressed into firm engagement with the projections 8, with a uni- Serial No. 232,431.
form and even pressing action, by means of screws 16. The screws 16 effect this result by clamping together oppositely disposed pairs of cooperating cars 18 that are disposed on the opposite sides 14 and 15 along the.
'The tube is thus firmly and uniformly held against the projections without danger of loosening, notwithstanding that the mounting may become subjected to severe and care less usage. The tube 14 may, if desired, be integral with one of the projections 8, but it is preferred to make it separate from both projections 8, as it may then be blanked out of sheet stock, ears 18 included, and then bent into final shape. If the integral construction is employed, the cars 18 may be soldered to the sides of the tube.
Each projection 8 comprises a first part 24 that extends forward, away from the wear er, and a second part 26 that extends inward toward the other rim, in a direction substantially parallel to the plane of the rim and at a height considerably above the center of the rims 2 and 4. It is the part 26 that extends into the slotted tube. This construction has two advantages, among others: first, it provides for adjustments for all pupillary disstances so that a single mounting may be adjusted to pupillary distance and shape of forehead of any wearer, and secondly, the clamping ears 18 may be positioned at the rear of the part 26, adjacent to the part 24 and at the bend between the parts 24 and 26, so as to be inconspicuous, and yet far enough away from the wearers face so as not to engage it. The better to effect these objects, the ears 18 are provided at the very terminals or ends of the slotted tube. The projections are made suificiently thick to permit of the necessary adjustments without breaking. The adjustment is of such nature, furthermore, as to permit tilting either lens out of the plane of the mounting.
Modifications will obviously occur to per sons skilled in the art, and all such are con sidered to be included within the spirit and scope of the invention, as defined in the appended claims.
What is claimed is:
1. An ophthalmic mounting comprising two lens-holding members each having a projection, a tube longitudinally slotted along one side only of the tube, the projections extending into the tube through opposite ends of the tube, and clamping means for contracting the edges of the tube along the slot to force the walls of the tube into engagement with the projections.
2. An ophthalmic mounting comprising two lens-holding members each having a projection, a slotted tube provided along the edges adjacent to the slot with oppositely disposed ears, the projections extending into the tube through opposite ends of the tube, and means for clamping the ears on opposite edges of the slot together to press the walls of the tube on opposite sides of the slot into engagement with the projections.
3. An ophthalmic mounting comprising two lens-holding members each having a pro jection a first part of which extends forward and a second part of which extends inward substantially parallel to the plane of the rim, a slotted tube provided along the edges adjacent to the slot with oppositely disposed terminal ears arranged in pairs, the second parts of the projections extending into the tube through opposite ends of the tube, and a screw for clamping each pair of ears together to press the walls of the tube on opposite sides of the slot into engagement with the projections, the clamped-together ears being disposed at the rear of the second parts of the projections and adjacent to the first parts of the projections.
In testimony whereof, I have hereunto subscribed my name.
GEORGE H. DAY.
