ALBERT S. WEAVER, OF PROVIDENCE, RHODE ISLAND, ASSIGNOR OF ONE- HALF TO GEORGE HOBART, OF SAME PLACE.

EYEGLASSES.

SPECIFICATION formingpart of Letters Patent No. 543,363, dated July 23, 1895 Application filed November 21,1894. Serial No. 529,461. (No man.)

' State of Rhode Island, have invented certain new and useful Improvements in Eyeglasses; and I hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification.

This invention has reference to improvements in what are known as spring-bar eyeglasses, in which the nose-bridge is made in two parts which are connected to a horizontal bar on which they slide, so that the glasses are adjusted on a horizontal plane.

The object of the invention is to secure greater strength and economy in construction.

Another object of the invention is to provide a flexible and automatically-adjustable cushion bearing on the nose.

'The invention consists in the peculiar and novel construction which will be more fully described hereinafter, and pointed out in the claims.

Figure 1 is a side view of a pair of eyeglasses provided with my improved springbridge and nose-cushions. Fig. 2 is a top view 7 of the same.- Fig. 3 is a vertical sectional view showing one bridge-piece with its nose-cushion. Fig. at is a view of the bar-blank, and Fig. 5 a sectional view of the bar. Fig. 6 is a view of the blank from which one-half of the bridge is made. Fig. 7 is an edge view of the blank shown in Fig. 6 after the same is bent to form one-half of the bridge. Fig. 8 is a perspective view of one of the nose-cushions.

In the drawings, 10 10 indicate the rims of the lenses; 11 11, the posts secured to the rims and projecting therefrom, to which the bridge-pieces are fastened in the usual manner by means of the screws 12. Each half of the bridge is made of one piece of metal stamped out by suitable dies into the blank shown in Fig. 6. forms the rod around which thespiral spring lis placed, 15 the upper bearing, 16 the lower bearing, and 17 the recess into which the bar 18 enters. 19 forms the bent portion of the bridge, and 20 the support for the nose-cush- On this blank the part 13 ion, on the upper and lower ends of which the pintles 21 21 are formed, on which the frame of sheet metal 22, having the bent-over perforated ends 21' and provided with the cushion 23, is pivotally connected. The bar 18 is formed by stamping the blank shown in Fig. 4: from sheet metal and bending up the perforated ends 24..

In associating the parts neither skilled labor nor mechanical knowledge is required. The blank shown in Fig. 6 is bent either to the right or left. It is then'inserted into the slot 18 of the bar 18. The spiral spring 14 is placed over the rod 13, the end of which is passed 6 5 into the hole of the end 24c of the bar 18. The ends 21 are sprung so as'to pass overthe pintles 21, and thus the nose-cushions are secured, when the bow is secured to the posts' 11 by the screws 12 in the usual mannenthe .whole forming a strong yet light and durable bridge for eyeglasses, automatically. adjustable, that can be manufactured and sold for less money than spring-bar eyeglasses as heretofore constructed.

My improved spring-bar bridge is applicable to lenses without rims, in which the posts are secured to the glasses direct. I

Having .thus described my invention, I claim as new and desire to secure by Letters Patent 1. In spring-bar eye-glasses, the combina tion with the two lenses and the posts, of two bent metal-blanks each comprising a support for the nose-cushion and a spring-supporting 8 5 bar, and a bar provided with ways for the bridgepieces and abutments for the coilingspring; the whole adapted for automatic adj ustment, as described.

2. In spring-bar eye-glasses, the combina- 0 tion with the two lenses and the posts, of the adjustable bridge-connection consisting of a bar provided with ways and bent-up perforated ends, two bent metal-blanks each "comprising in one piece the support for a nose- 5 cushion, the recesses 17 and'the rod 13, and the coiled-springs 14: each abutting against a bent-up perforated end of the way-bar and the recessed portion of the blank, as described.

3. In spring-bar eye-glasses, the combination with the lenses and the posts 11, of the .bar 18 provided with the bent-up perforated In Witness whereof I have hereunto set my hand.

ALBERT s. WEAVER.
