WILLIAM H. BOUTELLE, OF SOUTHBRIDGE, MASSACHUSETTS, ASSIGN'OR TO AMERI- CAN OPTICAL COMPANY, OF SOUTHIBRIDGE, MASSACHUSETTS, A VOLUNTARY AS- SOCIATION OF MASSACHUSETTS.
OPHTHALMIC MQUNTING.
Application filed April 18, 1922,
To all whom it may concern:
Be it known that I, WILLIAM H. Bou- TELLE, a citizen of the United States residing at Southbridge, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Ophthalmic Mountings, of which the following is a specification.
This invention relates to new and useful. improvements in ophthalmic mountings and more particularly to means for fastening lenses to a nose bridge, temple or the like. The main object of the present invention is the production of a new and improved means for fastening a lens in position in its mounting in such a manner that the lens will be brought and held tightly in close engagement with the mounting, and relative movement of the parts will be prevented.
The further object of this invention is the provision of means for tightening a lens against the edge engaging portion of a strap or clip, said means being arranged either at the direct fastening point or disposed between the edge of the lens and the adjacent portion of the strap.
A still further object of the invention is the provision of tightening means of the above character which can be quickly and readily applied during the fastening of the strap to the lens and adjusted after the fastening has been applied or the same may be arranged within the strap before fastening the same to the lens and then adjusted after the strap has been secured to the lens. Either method carries out the purpose of my invention to bring the edge engaging portion of the strap and the edge of the lens in a tight fitting engagement with each other to prevent relative movement of the parts.
With the above mentioned objects in view the invention consists in the novel features of construction, the combination and arrangement of parts herein-after more fully set forth, pointed out in the claims and shown in the accompanying drawings, in which-- Figure I is a front elevation of a pair of eyeglasses embodying my invention.
Figure II is a detailed longitudinal sec:

tion taken through one of the lens clips showing my improved tightening device arranged between the edge of the lens and the edge engaging portion of the strap.
Figure III is a similar view showing a slightly modified form of the invention the parts being-in disassembled relation.
Figure IV is a longitudinal section of the form illustrated in Figure III showing the same in an assembled position.
Figure V is a similar view illustrating another form of the invention, and
Figure VI is a longitudinal sectional view illustrating still another form of the invention.
Referring now more particularly to the drawings inwhich my invention is clearly illustrated I have shown the device embodied in a pair of eyeglasses comprising the nose bridge 1, the lens 2, and the strap 3, which are carried by the ends of the nose bridge and adapted to be secured to the lens 2. Considerable difficulty has heretofore been experienced in fastening straps to rimless eyeglasses and bringing the edge of the lens into close contact with the edge engaging portion of the lens strap so as to clearly retain the lens in its proper position in respect to the nose bridge 1. It is the main ob jectof my invention to provide means adapted to be used in connection with the fastening of the strap to the lens to take up any space which might be between the edge of the lens and the intermediate portion of the strap after the fastening screw has been placed in its proper relative position.
In Figure II I have illustrated. one form of the invention wherein the ears 4 are provided with the lined openings 5 adapted to coincide with the opening 6 in the lens to provide a direct opening through the strap and lens. In order to securely fasten the ears of the strap to the lens a tubular member 7 is fitted into the openings 5 and 6, said tube having its end swaged outwardly to form a retaining rim 8 which contacts with a portion of the outer face ears 4 and thus retains the lens 2 in position between the ears l.
The ears 4,: are provided with the adjacent edge engaging portion 9 with inwardly tapering openings 10 and fitted within these openings are the tapered sleeves or cams 11, the smaller ends of these sleeves being adapted to contact with the edge of the lens as shown in Figure 2 to till up the space between the edge of the lens and the portion 9. The interior of one or these sleeves orca-in-s 11 .is threaded, the other sleeve being provided with a central opening and fitted into the sleeve is a tightening screw 12 that when screwed inwardly will move the sleeves toward each other forcing the tapered side walls of the sleeves or cams 11 into contact with the edge 2, so as toentirely fill any space which mightremain between the edge of the lens 2 and the intermediate portion 9 and by wedging the lens against the fastening 6 prevent rocking movement of the lens in the strap.
In Figures III and IV I have illustrated another form of the invention wherein in place ofthe sleeves-or cams 11 heretofore described I employ a rotatable cam member 13 which extends through the lined openings 14- in the ears 4-, this-cam having a central recess 15 which is adapted to face the opening end of the strap when placed in position so as to receive the edge of the lens as shown in Figure III. The ears 4: are then secured in posit-ion upon opposite faces of the lens ,byinserting the sleeve 16 into one end of the continuous openings through the lens and ears and inserting through the opposite side, screws 17 adapted to engage the threads upon the interior sleeve 16 whereby tightening of the screw 17 will move the sleeve 16 inwardly, to securely clamp the ears 4E in con- ,tact with the opposite faces of the lens. After the cars have been attached to the lens the member 18 is rotated, its ends being mounted into suitable bearing openings in the strap, so as to bring the cam face of the member 13 into contact with the edge of the lens as shown in Figure IV, it being understood that the cam surface of the member 13 will be sufficient to take up any loose movement be tween the edge of the lens and the intermediate portion of the strap.
In Figure V I have illustrated a slightly modified form of the invention wherein the adjusting or tightening means is combined with the strap fastening means and comprises two tapering sleeves 18, the inner ends ,of said sleeves being tapered off as at 19 while the outer ends 20 extend parallel with the walls of the openings in the ears 4.
These sleeves 18 are connected by means of a threaded pin 21. In placing these sleeves to pin in position within the opening in the lens and ears, one end of the pin can be attached to one of the sleeves and then inserted through the opening in the lens and strap for engagement with the opposite sleeve. The turning movement on the sleeves which are provided with transverse slots will tend to draw the inner ends of the sleeves 18 inwardly so that the tapered portion 19 will. contact with the wall of the opening through. the lens, forcing the lens toward the intermediate portion of the strap and thus take up any looseness between the edge of the lens and-the strap.
In Figure VI I have illustrated another form of theinvention'which is very similar to that shown in Figure V with the exception of the sleeves 23 which are continuously tapered. The sleeves 23 are arranged in position, the smaller ends being toward each other, and the pin or screw Ztis threaded in to said sleeves. On tightening of -the-screwthe sleeves 23 will move toward each other bringing the tapered outer side over into contact with the walls of the opening in'thelens and the inner edge of the apertures in-the strap ears, forcing the lens toward the intermediate portion ofthe lens strap. It will be readily apparent that in this form ofthe invention the device can be readily and quickly assembled or disassembled, as through turning the screw 24 the sleeves 23 maybe readily moved toward the ears.
While I have shown and described various means for use in connection with the fastening means of an ophthalmic mounting which is particularly adapted for fasteningthe lens straps or clips on to the lens, for taking up any space between the edge of the lens and the intermediate portion of the strap, it will be understood that various changes in the construction and location of the parts may be carried out without departing from the scope of my invention.v
What I claim is:
1. A device of the class described includinga lens having an opening therethru, a strap member having its ears arranged upon opposite faces of the lens, means extending thru the ears of the strap and the opening in the lens for retaining said strap in position,
said strap having a transverse opening, ta,,
- openings and a cam member arranged within said openings and adapted to be disposed between the intermediate portion of the strap and the edge of thelens to take up any looseness between the lens and the strap.
' A lens strap having spaced ears to receive a lens tlierebetween, said ears having aligned apertures to receive a transversely extending fastening member and having additional transverse apertures, and means tures being adapted to receive a fastening device extending through a lens, and cam means engaged in the other apertures for 10 engagement With the edge of a lens to force the engaged portion in the direction of the fastener receiving apertures.
WILLIAM H. BOUTELLE.
