Application filed October 9, 1917, Serial No. 195,601. Renewed April 17, 1919.

To all whom it may concern 7 Be it known that I, EUGENE G. BERNHEIM, 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 Eyeglasses, of which the following is a specification.

My invention relates to improvements in eyeglasses and refers particularly'to the type orcharacter of eyeglasses known as finger lever eye-glasses. i V

In eye-glass mountingsof the finger lever type and in general and commonuse having long'tubular bearings it has been found that by perspiration becomes deposited upon and between the. two tubular bearings of the mounting forming a thick coagulated substance which in time covers or coats said bearings and considerably reduces the efiicien'cy' and proper easy action of the parts and further destroys the resiliency or quick action of the actuating springs, due to the congealing of the said 1 matter between the two tubular bearings.

The main object of my invention is the provision of an eye-glass mounting employing tubular bearings which will convey the said coagulated matter away from between the bearing faces of the tubular bearings and'prevent its coagulating at points which would impede or interfere with the action of the springs or the proper movement of the tubular bearings, thus overcoming the serious defect and objection noted. f

Other objects of my invention are the pros vision of an eye glass mounting of extremely simple construction whose parts may be quickly assembled with the fingers; in which absolute accuracy and automatic alinement of the parts are assured; which provides a broad bearing surface for the telescoping cylinders and prevents undue strain or wear upon individual parts; and which requires practically no time-wasting adjustment of parts to insure absolutely perfect lens alinement.

Still further objects of the invention are the provision of a mounting which will have I a greater amount of bearing surface than ordinary mountings of this character; which will eliminate entirely the strain or wear upon the pivot screw; which will reduce the Specification of Letters Patent.

the tubular bearings and posts to receive and retain the oleaginous matter and prevent its coagulation between said posts and tubular bearings. r

The invention further consists of an eyeglass mounting embodying novel features of construction and combination of parts for service substantially as shown, described and particularly defined by the claims.

In order'that the details of construction and operation of my mounting may be understood and its many advantages be appreciated, I have shown in the accompanying drawing an eyeglass mounting constructed according to my invention.

Figure 1 is a front elevation of an eveglass mounting constructed in accordance with and embodying my invention.

Figs. 2, 3, 4, 5, 6, 7 and 11 are sectional views of modified forms of my improvement.

Fig. 8 is a. detail view'illustrating the evolutions in the method of forming the tubular bearing on the tables of the bridge.

Fig. 9 is a detail view of one of the guard levers, showing the evolutions from flat m etal in producing the drawn up tubular bearings to fit upon the tubular bearings shown in Fig. 8, and v Fig. 10 shows the blank metal before and after the guard lever has been blanked out and superfluous metal has been removed.

In the drawings:

The letter A designates the lenses; B the clips; 0 the straps; D the bridge formed with the tables E. and F the finger levers 1 which carry guards.

lllwlllluj. UL lLlLbLklll integral part of the stock of the bridge and lever which is the preferred manner of making this tubular bearing, and which is accomplished by punching, stamping or drawing out the tubular bearing direct from the stock of which the levers and bridge are made, thus avoiding soldering or brazing which weakens the stock and retaining unimpaired the original stilfness of the metal.

The several forms or modifications shown illustrate practical structures for carrying my invention into effect, but I wish it understood that the main and essential feature of my invention consists in the location of a chamber between the rigid hearin or support and the tubular bearings on the levers, which would act to collect the matter from the skin induced by prespiration, and for a long period of time prevent its accumulation or clogging, as at present, owing to the limited space between the posts and tubular bearings, which accumulation more quickly destroys the resiliency or quick action of the springs.

It will also be noted that my improvements provide bearings at the top andbottom producing bearings having less friction than the tubular bearings made of continuous metal and thereby forms the cavity or chamber as before noted.

Copies of this patent may be obtained for tubular bearings and retained in pivots and tiibular bearings to form receptacles.

4-. An eye-glass, consisting of the lenses, bridge and lever carrying guards, posts rising from the bridge and each formed with a head, tubular bearings carried by the le vers and pivoted on theposts, a chambered portion between the posts and tubular bearings and actuating springs coiled around the position by theheads on said posts.

5. An eyeglass, consisting of lenses, bridge, supports mounted in said bridge, levers having tubular bearings fitting on said supports, a chamber disposed between the said supports and bearings, and actuating springs for the levers disposed upon said tubular bearings.

6. An eyeglass, consisting of lenses, bridge, supports mounted in said bridge and formed with a head, guard carrying finger levers having tubular bearings mounted on said supports, a chamber between said supports. and tubular bearings, and actuating springs for the levers disposed upon said the heads of the supports. I

.7. An eyeglass, consisting 'of lenses, bridge connection, vertical supports on said bridge connection, levers carrying guards. and having tubular bearings mounted on the vertical supports, and means between the supports and tubular hearings to receive secretions or discharged matter from the skin of the nose.

. In testimony whereof I 'aflix my signature in the presence of two witnesses.
