EYEGLASSES on SPECTACLES.

SPECIFICATION forming part of Letters Patent No. 782,57 5, dated February 14, 1905.

i Application filed May 11,1903. Serial No. 156,703.

T0 (all whom, it HMI/:7] concern,.- l Be it known that I, DAVID HUNT LUDLow, citizen of the United States, residing at Easton, in the county of Northampton and State of Pennsylvania, haye invented certain new and usefulImprovements in Eyeglasses or Spectacles, of which the following is a specification.

The principal objects of my invention are to secure greater adjustability and eiiciency in the nose-rests. I attain these objects by the means hereinafter explained. e

Devices embodying myimprovements are represented in the ,accompanying ldrawings and hereinafter described and claimed.

In the drawings, Figure 1 is a perspective view (from the left and rear) of a pair of eyeglasses embodying my improvements, which are also applicable to spectacles. Fig. 6 shows same as seen from above. Figs. 2, 3, 4", 7, 8,

9, 10, 12, 14, 16, 17,*18, 19 are perspective views of typical embodiments of my invention removed from the clamping-posts, illustrating various modes and phases of adjustment. Figs. 5, 11, 13, 15 show ,typical patterns in the fiat.

Similar letters ofV reference indicatel corresponding parts.

Z represents the lenses, and p the clampingposts, which are typical of any convenient means of attachment.

n represents any suitableform of nose-rest,

carried by an arm c/tj, which in turn is se cured to the clamping-post by theJ screw s or any other appropriate means.

is the ordinary spring connecting the clamping-post and is typical of any spring or bridge connecting the lenses directly or indirectly, with or without the interventionof the nose-rests or their arms and whether resting on the nose o r not.

` is used with an arrow to show the location and axis of bendings of the flat patterns.

The characteristic feature of my invention is the carrying-arm of the nose-rest. It may be integral with the body of the nose-rest and with the clamping-post or not, kas preferred. c/tj in the drawings is intended to be typical of any carrying-arm having through at least part of its extentits iat surfaces substantially parallel to the axis of the lenses; but in the preferred construction it may be considered for purposes of description as consisting of three portions, (preferably but not necessarily continuous and integral with each other,) namely:

First. Aterminal limb fo, secured at itslens end to the clam ping-post p and at its other extremity continuous through asheer bend with the second portion next to be described, while its intermediate part free from the post is available for purposes of adjustment, especially that shown in Fig. 6, t being carried (by torsion or' o) to it', or vice versa. o preferably enters box of vertical way-post from below', as shown in most of the tigures; butit Y the previously-described limb with the third portion next to be described and having through at least part of its extent its fiat sur- `faces substantially parallel to the axis of the lenses. This limb affords adjustment around one or more axes substantially parallel to the axis of the lenses. It' may be made to give a wide range of adjustment, as exemplified in Figs. 7, 8, 9, 16, 17, 18, 19, and notably afree adjustment of the body of the nose-rest upward, as shown typically in Figs. 16, 18, and downward, as shown typically in Figs. 17, 19, a much-needed adjustment not practicable with the forms of nose-rest now in use.

Third. A junctional portion (represented in the drawings by the fold j) which is intended to be typical ofA any adjustable means of connecting the carrying-arm with the body of the nose-rest whether integral (preferably) or otherwise. It may join the body of thenoserest at its top or bottom or any intermediate point and at its anterior edge or posterior edge orv anywhere between; but it is preferably made integral with the body of the nose-rest `may be made to enter from above, or a trans-l IOO near the middle of its posterior edge, as shown in the drawings. 7' completes the capability of adjustment of the body of the nose-rest on the arm at the posterior end of the latter. If a fold be used for this purpose, as preferred, its conveXity may be turned in any suitable direction.

It is evident that with a carrying-arm substantially as described the body of the noserest can readily be adjusted to any conceivable position, a desideratum not heretofore attained.

Having thus described my invention, I claim and desire to secure by Letters Patent- 1. A nose-rest provided With a carrying-arm having through at least part of its free portion its flat surfaces substantially parallel to the horizontal axis of the lenses and through at least part of its free portion its flat surfaces substantially vertical.

2. A nose-rest provided with a carrying-arm having through at least part of its extent its flat surfaces substantially parallel to the horizontal axis ot' the lenses and having a fold at its junction With the body of the nose-rest, substantially as described.

3. Anose-rest provided With a carrying-arm having fiat surfaces Whose normals point substantially laterally, vertically and antero-posteriorly, substantially as shown.

4. A nose-rest, n, provided with a carryingarrn consisting of the three portions o, L and j, o and L having their Hat surfaces substantially vertical and'horizontal respectively, substantially as described.

DAVID HUNT LUDLOVV.
