Application filed September 17, 1923. Serial No. 663,180.
This invention relates to improvements, in ophthalmic mountings, and has particular reference to that form of mounting in which adjustable means are employed for insuring correct positioning of the mounting on the face, and additional holding means are employed for securing the mounting in position.
An important object of the invention is the provision of an improved mounting of this type in which the various parts shall be detachably connected and of standard construction to permit of removal, replacement and interchangeability of the parts as desired; the provision of adjusting means whereby the supports and the anchoring means may be easily conformed to the facial requirements of the wearer, and a simplification of construction whereby the various parts may be accommodated in minimum space and present the most attractive appearance.
Another very important object of the invention is to provide a mounting of this character having a pair of independent guard members mounted upon a pivot, one of which members is pivotally mounted, while the other or lower guard is locked against rotation, both of said guards being provided with loop members to allow for proper adjustment to the users face.
A still further object of the invention includes the provision of an ophthalmic mounting which may be readily adjusted to comfortably yet securely fit and engage the nose, and a general simplification of the details of construction of mountings of this character whereby the same may be readily produced in large quantities.
Other and important objects of the invention will become ap arent during the course of the following escription.
In the drawings, wherein like numerals are employed to designate like parts throughout the same:
Figure 1 is a front elevation of my invention in use.
Figure 2 illustrates a fragmentary side elevation showing the parts disassembled.
Figure 3 is a detail of the pivoted guard member, and
Figure 4c is a detail of the lower or rigid guard member.
In the drawings, wherein for the purpose designates the lenses secured within the clips 2 carried by the bridge 3 by screws or other customary lens securing means.
Located at each side of the mounting and forming a part of the bridge 3 is a seat member t, on which is mounted the extremity 5 of the guard 6, said extremity 5 having the notch 7 receiving a portion of the strap to facilitate the locking of the guard'against rotation.
The guard 6, as is clearly shown in Figure 4, is provided with a loop 8 whichhas a portion extending rearwardly from the bridge and then turning forwardly to the attachment of the guard pad 9 to permit of the proper-adjustment of the lower pad upon the face of the user. The usual guard pad 9 is rigidly mounted on the forward extension of the loop 8. Itwillbe understood, however, that any form of locking means may be provided to prevent rotation of the lower guard. A pivot or securing screw 10 passes through the portion 5 of the guard to the support, while mounted on the pivot and bearing against one face of the guard 6 is the tube 11, the pivot 10 having a shoulder 12 bearing against the outer portion of the tube to securely force the same downward onto the guard to clamp the guard in position. Turning on the tube is a guard lever 13 having an operating handle portion 14 which overlies the front of the lens at one end and has a looped portion 15 at the other end which has a rearwardly extending portion, a turn and a forwardly extending portion terminating in an angular extension 16 to form means whereby a guard pad 17 may be rockingly mounted thereon. An actuating spring 18 is provided for swinging the lever into clamping position, although I do not restrict myself to the particular form of spring illustrated.
When in use it will be seen that the lower guard will be locked against rotation while the upper guard will be pivotally mounted and may be so pivoted by means of the handle operating end 14. of the guard 13, while the spring 18 will turn the guard lever 13 to its normal position when pressure has been released from the operating end. Due to the fact that the loop 15 is provided and that the pad 17 is loosely mounted thereon,
the guard pads to be adjusted in, out, up or down, as required or to the desired angle by bending.
It is to be understood that the form of my invention herewith shown and described is to be taken as the preferred embodiment of the, same and that various changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subj oined claims.
'Having thus described my invention,
what I claim as new is:
1. In a device ofthecharacter described, in combinationwith a pair of lenses, abridge connecting the lenses, pivots at each end of the brid e, a lever on each pivot having a projecting. handle overlying the front surface of a lens, and a rearwardly projecting arm having a loop portion extending rearwardly from the arm'and then forwardly, a nose guard, on the forwardly extending portion of the loop, a second arm on each pivot held against rotation, having a rearwardly extending arm and a loop portion extending rearwardly from the arm and then forwardly, and a nose guard secured to the forwardly extending portion of the loop portion. r
2. A device of the character described in combination with a pair of lenses, a bridge connecting the lenses, pivots at each end of the bridge, a lever on each pivot having a projecting handleoverlying the front surface of a lens, and a rearwardly projecting arm having a loop portion extending rearwardly from the arm and then forwardly, a nose guard on the forwardly extending portion of the loop, a second arm on each pivot held against rotation having a rearwarclly extending arm and a loop portionextending rearwardly from the arm and then forwardly, a nose guard secured to the forwardly extending portion of the loop portion, a bushing having a flange and a central orifice on each of the pivots, said bushing resting on the second arm and extending through the first arm, the flange overlyingfthe first arm, a spring for cooperating with the first arm, and a pivot screw'through the bushing to hold the parts in alignment.
