Application filed July 1(1), 1913.

T 0 all whom it may concern Be it known that l, .losnrri E. HIGGINS, a citizen of the United States, residing at Grand Island, in the county of Hall and State of Nebraska, have invented certain new and useful Improvements in Eyeglasses; and ll do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to optics, and more especially to eyeglasses although it is susceptible of use with spectacles; and the object of the same is to produce an improved automatic nose grip having spring-pressed means for grasping the bridge of the` nose and manually-operable devices for retracting the guards out of pinching or pressing condition when it is desired to remove the eyeglasses.

Heretofore nose grips of this kind have been applied to eye glasses by mounting the guards on vertical pivots so that they will swing in horizontal planes against opposite sides of the bridge of the nose, with finger pieces whereby they might be retracted or drawn apart when it was desired to remove the eyeglasses. But l have found that the bridge of the nose, whether it is thin or ieshy, generally has its exterior side walls converging toward each the face so that where the guards swing on vertical pivots they make contact with flesh at points where the latter is unfortunately so shaped that, especially if the skin be moist, they often slip off. l have therefore conceived the idea that if the guards are mounted on or moved by devices which are disposed in a horizontal plane, or even if the guards are themselves mounted on vertical pivots and swung by devices which rock in a vertical plane, the faces o-f the guards are thrown against the sides of the bridge of the nose by pressure exerted in such a direction that they will not slip oif. The present invention illust-rates means for carrying out this `idea in two ways, as described in the following specification and shown in the drawings wherein- Figure l is a perspective view showing one form of my invention, and Fig. 2 a perspective view showing another form. Fig. 3 is an enlarged perspective detail which will be referred to hereinafter.

I have conventionally illustrated the lenses L connected by mountings M to the ends of Specification of Letters Patent.

the bridge B, the latter being here a saddlebridge of the well known type, and I have sho-wn guards G which are spring-pressed against thesides of the bridge of the nose as usual. These parts form elements of my inventionY as. a whole, but no novelty is claimed as to their detailed structure. ln the type of my invention.illustrated in Fig. l, the guards have ears l projecting outward from them and pivotally connected with the yet to be described; whereas in the device illustrated in Fig. 2 the single guard therein shown is illustrated as provided with an integral tongue 2 bent around behind it and pivoted as at 3 to a bridge-arm 4l, the pivot in this case being upright 1n order to illustrate that my invention will operate with a pivot which is upright if desired. The pivot 10 in Fig. 1 is horizontal, as will yet be described.

rlhe feature of this invention which is common to all types is that on the bridgearm Il l provide bearings 5 in which is journaled a rock shaft 6 whose forward end is cranked as at 7 and carried outward over the mounting M and forward of the lens L where it terminates in. a bent finger piece 8, whereas its inner end is cranked as at 9 and connected with the guard. ln Fig. l the connection isby means of a pivot l0 whereby the crank is directly connected with the ear l. ln Fig. 2 the crank 9 projects downwith a bend formed in the tongue 2. When now the wearer places his thumb and finger astride the two finger pieces 8 and rocks them in the proper direction, it will be clear that the cranks 9 are correspondingly moved. lf thesev cranks directly carry the guards Gr as seen in Fig. l, the guards move with them; but if the cranks pass through the supports 2 for the guards as seen in Fig.

2, the guards are drawn away from the nose although they yet turn on their individual pivots 3, whatever the direction of` the latter. .F or throwing the guards toward the nose l also provide a feature which is common to any type of my invention, as shown in the drawings. This consists in a spiral spring ll coiled on the rock shaft 6 and having one end l2 engaging the bridge-arm l while its other end engages the shaft. The manner of this engagement is unimportant, but I preferably pass it into a socket 13 formed in the end of a pin la which latter projects from a collar 15 that 1s fast on the rock many respect further than .as set shaft beyo-nd its outermost bearing, and the latter is provided with an arc-shaped recess 16 in which the pin moves freely as the shaft and with it the collar is rocked to and fro. The disposition of the collar on the rock shaft will be such that the uncoiling of the spring 11 throws the pin 14 against one end of the recess 16 and projects the guard G inward as far as necessary to cause it to make contact with the thinnest nose; whereas the length of said recess is such that when the pin 14 is moved over against the other end wall by the wearer in the manner above described, the guard will be retracted to its greatest eXtent so that it will be drawn out of contact with the thickest nose. I do not wish to be limited in this respect, or, in fact, A forth in and the proportions are obviously not esoperation of this inthe yfollowing claims; and materials of parts sential to the successful vention.

What is claimed as new is:

1. The combination with a hose-bridge having at each end a lens-mounting, the guards, and a curved supporting arm for each guard connected with its mounting on an upright pivot; of a pair of horizontally i connecting the remote end disposed spring-actuated crank shafts carried by said mountings with their cranks moving through substantially vertical planes and disposed within said curved arms, and means for turning said shafts manually.

2. The combination with a hose-bridge having at each end a lens-mounting; of bearings o-n said mounting, a horizontally disposed rock shaft mounted in said bearings and having its forward end deflected laterally into a finger piece and its rear end cranked, the guard, an arm integral therewith and bent around behind it so as toy loosely embrace said crank, an upright pivot of said arm with the mounting, and a spring normally turning said shaft in a direction to bear the guard toward the center of the bridge.

3. The combination of a nose bridge having at each end a lens-mounting, bearings on thelsame having arc-shaped recesses, forwardly and rearwardly extending rock shafts mounted in said bearings and having -finger .pieces at their front ends, guards movable toward and from the bridge and actuated by the cranks on the inner ends of said shafts, collars fixed on said shafts and having laterally projecting pins to work in the arc-shaped recesses ofsaid bearings, said pins having sockets in their ends and springs coiled on said shafts and each having one of its ends anchored to one of the mountings and its other end inserted in the socket in one of said pins.

4. The' combination with a nose-bridge having at each end a lens-mounting; pair of bearings on said bridge near each end, one of which has a recess, a horizontally disposed rock shaft mounted insa-id bearings and having a finger piece at its forward end and its rearward end cranked, a guard, a tongue projecting therefrom and pivoted to the mountings, said tongue being loosely engaged by said crank, a spring turning the shaft so that its crank presses the guard normally toward the center of the bridge, and a collar fast on said rock shaftl and having a pin moving in said recess.

5. The combination with a nose-bridge having at each end a lens-mounting; of a pair of bearings on said bridge knear each end, one of which has4 an arc-shaped recess, a. horizontally disposed rock shaft mounted in said bearings and having its forward end deflected into a finger piece and its rearward end cranked, a guard movably connected with said crank, a spring bearing the guard normally toward the center ofthe bridge, and a collar fast on said rock shaft and hav'- ing a pin moving in said recess.

6. The combination with va nose-bridge having at each end a lens-mounting; of a pair of bearings on said bridge near each end, one of which has an arc-shaped recess,j a horizontally disposed rock shaft mounted in said bearings and having its forward end deiiected into a finger piece and its rearward lend cranked, a guard movably connected with said crank, a spring coiled lon said shaft with one end engaging the bridge, a collar Xed on .the shaft adjacent the recessed bearing and into the recess, and connections between the other end of said spring and this pin, for the purpose set forth. v

In testimony whereof Ihave hereunto set my hand in presence of two subscribing witnesses.
