SAMUEL ESKIN, OF NEW YORK, N. Y.

SELF-ADJUSTING- GUARD.

Specification of Letters Patent.

Application filed December 8, 1910. Serial No. 596,347.

To all whom it may concern:

Be it known that I, SAMUEL ESKIN, a subject of the Emperor of Russia, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Self-Adjusting Guards, of which the following is a specification.

This invention relates to eye glasses'and has for its object the product-ion of a selfadjustable guard therefor which is simple in construction and consists of a comparatively small number of parts.

Another object of this invention is the production of a guard which is self-adjustable and does not require any delicate mechanism to operate the same.

With these and other objects in view, this invention consists of certain novel constructions, combinations and arrangements of parts as will be hereinafter fully described and claimed, and it should be understood that this invention is susceptible of certain changes in construction as fall within the scope of the following specification and claims.

In the drawings :Figure 1 is a perspective View of a pair of glasses provided wit-h the improved self-adjustable guard. Fig. 2 is a sectional View through the spring looking at the side of. the guard which is attached to one end thereof. Fig. 3 is a front view of a portion of the glasses showing the connection of the guard and guard-arm in section. Fig. 4 is a detail perspective view of the guard. Fig 5 is a detail perspective of the guard-arm. Fig. 6 is a detail perspective view of a modified form of the guard and guard arm drawn apart.

Referring to the drawing by numerals, 1 designates the spring which engages at each end the channel head 2 of the studs 3. The studs 3 are provided with the usual straps 4 which engage the lenses 5. Positioned in the channel head 2 of the stud is one end of the guard arm 6 and said arm is secured within the head 2 by means of a screw 7 which passes through one of the adjusting apertures 8 formed in the upper end of said arm. The lower end of the arm 6 is curved inwardly and is provided with a punched cup-shaped socket portion 9 which has an aperture 10 formed therein. By reason of the apertures 8 being formed in the arm 6 it will be obvious that the arm may be readily adjusted to suit the wearer.

The guard 11 is of the usual shape or any other convenientshape and is provided with a cup-shaped socket portion 12 which has an aperture 13 formed therein. This cup-shaped socket portion is punched from the body of the guard thereby constituting a ball adapted to fit in the socket 9 formed in the guard arm. A screw, rivet or other fastening means 14 passes through the apertures 10 and 13 formed in the socket portion 9 and 13 re spectively. The guard 11 is loosely carried by the rivet or screw 14 and the head 15 is so carried within the socket 12 as to be at all times shielded therein. It will therefore be obvious that although the guard is loosely mounted on the guard arm the head of the securing screw will be held out of engagement with the nose of the wearer and will not be apt to irritate the same. A pair of laterally extending lugs 16 are formed upon one side of the guard 11 and straddle the guard arm 6 as illustrated in Figs. 1, 2 and In this way the guard will have only a limited rotary movement and will permit a lateral swinging movement.

It will be obvious that the guards 11 will readily adjust themselves to the nose of the wearer when the glasses are in use and that any slight movement of the head of the wearer will not be likely to throw the glasses oflf his nose, as is the case where the rigid guard is used, since a slight movement of the glasses is allowed relative to the guards.

In Fig. 6 a modified form of the guard and guard arm drawn apart is shown, wherein 11 indicates the guard which is provided with a cup-shaped socket-portion 17. The cup-shaped socket-portion projects upon one side of the guard and is provided with a laterally extending arm or finger 18. The guard arm 19 is used in connection with this type of a guard and this is provided with a socket portion 9 as in the preferred embodiment. A plurality of lugs 20 are formed upon the arm 19 and straddle the arm or finger 18 of the guard 11 for limiting rotary movement thereof.

What I claim is 1. An eye glass of the class described provided with a pair of guard arms, each guard arm comprising a cup-shaped socket portion, a guard carried by each guard arm provided with a punched socket portion eX- tending upon one side thereof and constituting a ball for fitting in said socket of said guard arm, securing means passing through said socket of said guard and said socket in 1 said guard arm, and having its head shielded within said socket of said guard, and means carried by said guard for limiting the rotary movement thereof upon said arm.

2. An eye glass frame of the class described comprising supporting means consisting of a plurallty of members, a universal joint connecting said members, integral lugs carried by one of said members and straddling a portion of said other member for limiting the rotary movement of one of said members upon the other member.

3. An eye glass frame of the class described comprising a guard arm, a guard, a universal joint connecting said guard and guard arm, integral laterally extending lugs formed upon said guard and straddling said guard arm for limiting the rotary movement of said guard upon said guard arm.

In testimony whereof I affix my signature in presence of two Witnesses.
