LENSJEASTENING FOR FSIQSE-GLASSEfi.

Specification of Letters Patent.

Fatented Jan. '7, 1908.

Application filed May EL 1907. Serial No. 372,679-

To all'who'm, it may concern:

Be it known that I, Gsone-n B. How, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain new and useful Improvements in Lens-Fastenings for Nose-Glasses, oi which the following is a specification.

T he object of my invention is to produce a stud member for connection with an eyeglass lens of any thickness, the construction being such that the connection with the lens may be readily made and unmade.

'l he accompanying drawings illustrate my invention.

Figure 1 is a magnified elevation of one form of in improved structure showing the adjacent ends of two lenses, one of said lenses being secured in position while the other has just been placed readyto'be secured, Fig. 2 a similar view of another form; Fig. 3 a section on line 3-3 of Fig. 1-; Fig. at a similar section of a modified form; Fig. 5 a similar section of another modification and Fig. 6 a section of the construction shown in Fig. 5, showing the manner of placing the lens.

In Figs. 1, 3 and 4, 10 indicates the main body of a stud provided at one end with flanges 11 between which may be secured, in an ordinary manner, a spring bridge 12 and nose-piece 13. Body 10 is provided at its lower end with a finger 14 which projects from one side of the flange 15 adapted to embrace the edge of the lens 16. Finger 14 on one face carries a pin 17, preferably tapered, the axils of which is substantially parallel with the inner curved face of the flange 15 and said pin is of a length preferably a trifle less than the thickness of the lens to be placed thereon. The lens 16 is of course to be provided with a tapered opening 18 to receive the pin 17 and fits snugly thereon.

in order'to hold the lens on the pin 1. provide a spring clip or finger20,which is rotatably mounted in the body 11. In order to adapt the structure to lenses of different thicknesses, the finger 20 is preferably adjustable toward and from the finger 14 in the direction of the axis of pin 17, and a convenient means of obtaining this adjustment, as Well as permitting a swinging movement of the spring finger 20, is to provide the spring 20 with a threaded stem 21 and provide a threaded opening 22 in the body 10 to receive the stem 21.

In Fig. 3 I show the opening 22 inclined slightly to the axis of pin 1'? so that, as finger 20 1S rotated on the axis of the threaded ortion 21, it will swing in a plane at an ang e to the face oi the lens and thus a proach the. lens more rapidly than the pitch ot the threads of stem 21. i find it desirable to provide the under taro 0i finger 20 with a small boss 20 adapted to seat itself in the end of the perforation .18 of the lens.

in Fig. 4 the stem 21 lies substantially parallel with the axis of linger 17, while in'Fig. 5 the pin 17 is provided with a threaded opening adapted to receive the threaded shank of the spring finger 20. I

Any desirable tension of the spring finger on the lens may be obtained by screwing the stem into and out of the threaded hole the required distance.

1 claim as my invention:

1. An eye-glass fitting comprising a main bod y having a lens-receiving finger, a ta ered pin carried by said finger, and as ring 'nger rotatably mounted on said main ody to cooperate with the lens-receiving finger.

2. Au eye-glass fitting comprising a main body having a lens-receiving finger, a pin carried by said linger, and a spring finger rotatably mounted on said main body to 00-- operate with the lens-receiving finger.

3. An eyeglass fitting comprising a main body having a lens-recciving finger, a tapered end carried by said finger, and. a spring finger cor'ipcrating with said first mentioned finger, said spring finger having a threaded stem screwed into a threaded opening formed through said main body 1. An eye-glass fitting comprising a main body having a lens-receivng finger, a pin carried by said finger, and a spring finger 00- operating with said first mentioned finger, said spring linger having a threaded stem screwed into a threaded opening formed through said main body.

An eyeglass fitting comprising a main body having a lens-receiving finger, a ta cred pin carried by said finger and aspring ger rotatably mounted on said main body on an axis at an angle to said tapered pin to cooperate with the lens-receiving finger. 6. An eye-glass lit'ting comprising a main body having a loin-receiving linger, a pin carried by said finger, and a spring finger rotatably mounted on said main body on an axis at an angle to the axis of the pin to cooperate with the leus-receiving linger.

7. An eye-glass fitting comprising a main body havi I aliens-receiving finger, ata ered l screwed into a threaded opening formed pin carried y said finger, and a spring ger oooferating with said first-mentioned finger. 1 sin spring finger having a threaded stem screwed into a threadedv opening formed. through said main body at an angle tothe axis of the pin. v

8. A11 eye-glass fitting comprising a main body having a lens-receiving finger, a pin.

carried by said finger, and a spring finger oooperating with said first-mentioned finger,

said spring finger'having a. threaded stem.

through said main body at an angle to the axis of the pin.

In witness whereof, I, have hereunto set my hand and seal at Indianapolis, Indiana, this eighth day of April, A. D. one thousand nine hundred and seven.
