EYEGLASS-MOUNTING.

Specification of Letters Patent.

Patented Oct. 29, 1912.

Application filed February 24, 1909. Serial No. 479,808.

'1 '0 all whom it may concern.

Be it known that I, Lao F. AM, of Albany, in the county of Albany and State of New York, have invented certain new and useful Improvements in Eyeglass-Mountings; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the referencenumerals marked thereon.

The present invention relates to eyeglass mountings, and more particularly to that type in which the nose guards are mounted to swing relatively to the support for the lenses; an object of the invention being to mount the springs in such a position that they will be inconspicuous when the mounting is viewed from the front, and a maximum resiliency will be obtained.

Another ob ect of the invention is to roride for mounting the springs in sue a manner that the latter may be quickly detached for the urpose of repair or the substitution of ot 1er nose guards without the necessity of employin separate fasteners which are not only liable to work loose and become lost but to increase the size of the mounting.

To these and other ends the invention consists in certain improvements and combinatinns of parts all as will be hereinafter more fully described, the novel features being pointed out in the claims at the end of the specification.

In the drawings :--Figure l is an enlarged front view of one embodiment of an eyeglass mountin showing portions in proximity to one of the guards; Figs. 2, 3 and 4 are respectively a rear, a to and a bottom view of the same portions; F 1g. 5 is a central vertical section of the mounting; Figs. (3, 7 and 8 are detail perspective views, respectively, of a )ortion of the support, a spring and a guar such as shown in Figs. 1 to 5, and F1 s. 9 and 10 are detail perspective views oi the support and a spring of another embodiment of the invention.

Referrin more particularly to the drawings A in icates tie lenses connected by a support comprising preferably a bridglng portion 1 having orizontal seats 2 at its ends rigidly secured to the lens attaching devices 3. Mounted to swing on the support, preferably in a horizontal plane, are the nose guards, the swinging in this instance being affected by a pivot pin 4 which may project upwardly from the horizontal Iportion 2 of the support to cooperate with a carin 5 on the guard, the bearing openin lateralTy so that the guard ma be remove from beneath the head 6 on t e upper end of the pivot or hearing 4.

Each guard preferably embodies a lever provided intermediately of its ends with the recess 5 and having one end rojecting forwardly of the plane of the enses and the other end projecting in rear of said lane, the forward end in this instance sing turned downwardly at 7 and outwardly at 8 to provide a finger piece. The rear end of the lever carries a nose bearin portion referably embodying upper pa 9 and ower pad 10, and having an arm 11 arranged intermediately of the pads and secured to an upright ortion 12 on the lever.

The spring of eac guard may be in the form of a true 5 iral coil 13 arranged in a. plane in rear of tie lenses and having a forwardly projecting arm 14 preferably operating on that side of the support op osite that on which its guard is mounte its outer end cooperating with its guard in advance of the pivot of the latter. As a means for securin each spring to the support, the latter may e provided with a pro ection 15 extending rearwardly from the rear face of the support and receivin the recessed 0rtion or socket 16 arranged above the coi 13 thus permitting the spring to be detached quickly from the support.

Accidental separation of the spring from the support may be prevented by providing the spring with a hook or recessed portion 17 at the forward end of the arm 14 to interlock with the recessed portion 18 on the guard in advance of the pivot. This form of the 5 ring may be made from flat stock with a ateral projection at one end, the lateral projection being bent transversely of the stock to provide the socket member 16 and the stock in roximity to the socket member being coiled about a vertical axis into a true s iral. That portion of the stock beyond t e coil 13 is twisted at 19 in order to present the (lat face at the extreme end of the spring horizontally, thus giving strength to the ortion which must receive the greatest strain.

In F i 's. 9 and 10 the connection between the spring and the support is established by providing a socket member 15 on the support to receive a projection 16" on the spring, the other )art of the mounting being, it desirable, the same as that shown in Figs. 1 to 8.

To remove the mounting from the nose of a wearer or to place it upon the nose, the finger pieces 8 are pressed together, thus separatmg the nose engaging portions in rear of the lenses, and upon the releasing of the finger pieces the nose engaging portions move together under the action of the springs. To remove a guard for the purpose of repair or to adapt. the mounting to a different nose, a hook portion 17 is disengaged from its cooperating recessed portion 18, thus permitting a bearing 5 to be separated from its bearing 4 by the lateral or sidewise movement of the uard, the spring remaining on the support by reason of the connections 15, 16. If it is desired to remove a spring without removing its guard 11 disconnection between the interlocked parts 17 and 18 is first effected when the spring may be moved rearwardly to separate the parts 15 and 16.

Eyeglass mountings constructed in accordance with this invention are inexpensive to manufacture and simple in operation. The springs for positioning the guards are so located that they are hidden behind the support when viewed from the front and the increased length of the forwardly projecting arm 14 produces an easier action in the guard. The interlocking connection between the sprin and the support and between the spring an the guard maintains these parts in proper operative relation while at the same time permitting an almost instantaneous detachment. The connections also dis )enses with the use of screw fasteners or 0t er independent fasteners which in addition to increasing the size of the mounting are liable to work loose and become lost.

I claim as my invention 1. In an eyeglass mounting, the combination with a support for the lenses and a nose guard mounted to swin on the support, of a spring unsupported between its ends, in rear of the support and having one end detachably interlocked with the sup ort and the other end detaehably interlocnd with the guard, both of said interlocking connections being held in engagement by the action of the spring.
