Aug. 9, 1938. r c. FISCHER 2 I CLASP FORGOGGLES Filed Feb. 25, 1937 wrlpnrllll INVENTOR Char/es Escher 1%,.

ATTORNEY Patented Aug. 9, 1938 UNITED STATES PATENT OFFICE 2 Claims.

The invention relates to improvements in clasps for goggles and has particularly to do with clasps for goggles used by aviators, drivers of racing automobiles, motor boats or any other apparatus 5 where a high speed is maintained.

The present invention has to do with an improved head band clasp and has for its object to provide a simple clasp which is adapted to lock the head band securely to the goggle, and which is not liable to break off or work loose from the goggle, while the goggle is being worn.

Other objects and advantages will become apparent as this specification proceeds. Referring to the drawing forming a part thereof:

15 Fig. 1 is a front elevation of the goggle embodying the improvements of the present invention;

Fig. 2 is an enlarged elevation of one form of improved head band clasp;

Fig. 3 is a section taken on line 3--3 of Fig. 2,

20 the hook being in its closed position; and Fig. 4

is a sectional view taken on line 4-4 of Fig. 2.

The goggle includes a pad in composed of soft rubber, provided with eye openings I I, and adapted to efliciently and comfortably conform to the 25 face of the wearer. Surrounding the eye openings and secured to the pad are light metal frames 2, hinged together at i3 and adapted to carry the lens members l4. Members 15 at the sides of the frame carry perforated lugs l6 which are utilized 30 as eyes for the hooks of the head band clasp hereinafter described.

Heretofore, the head band has carried a thin light open ring which was passed through the ears of the frame and then twisted by pliers. The

35 twisting of the ring strains it and crystallizes it.

Thereafter, the stresses to which the ring was subjected imposed further strain and led to breakage at the point of twisting.

The possibility of the head band clasp breaking 40 or working loose from the goggle and the resulting inconvenience and perhaps danger to the user, is avoided by the clasp shown in Figs. 2, 3 and 4c, in which a strap 23 is provided, slotted at 24 to receive one end of a head band 25. The

45 strap has a forwardly extending pocket 26, the strap and pocket being stamped from one piece of metal. Passing through the sides of the pocket is a pivot pin 21, and a strong hook 28 is pivoted on this pin. As illustrated, pivot pin 21 is ar- 50 ranged off-center, i. e. below the central horizontal plane of the pocket and below the line of force acting on hook 28. This arrangement results in the hook being securely locked to the frame when in closed position. In addition, the upper sides 55 of pocket 26 are pinched at 29 to provide a pair of spring jaws. When the hook is open, as shown in full lines in Fig. 2, the jaws act to hold the hook up and in a position which facilitates the passing of the free end of the hook through the perforated noses of the frame. When the hook is closed, the jaws give way to allow the hook to pass and then spring back behind the hook. Also, as shown, the extended lip 30 of pocket 26 is adapted to be engaged by and serve as a stop for the free end of hook 2B.

The above-described clasp is adapted to overcome the difiiculties experienced with prior types. 0 There is no twisting of the clasp to attach it to the frame, and, consequently, no premature straining of the hook, which would lead to breakage. The clasp is adapted to securely lock the head band to the goggle and the possibility of the clasp opening and the head band becoming disengage'd from the goggle, is avoided with certainty.

It will be understood, that, in carrying the invention into practice, changes may be made in the improvements described, without departing from the principle thereof.

I claim:

1. A clasp for goggle head bands comprising a slotted head band receiving member, a hook receiving member attached to one side of the head band receiving member, said hook receiving memher being U-shaped in cross-section both longitudinally and transversely, and a hook pivoted in said hook receiving member adjacent the juncture of the longitudinal and transverse closed edges thereof and extending toward the open side of said hook receiving member, the free end of said hook engaging the longitudinal closed edge of said hook receiving member at a point remote from the pivot of said hook when the hook is in the closed position.

2. A clasp for goggle head bands comprising a slotted head band receiving member, a hook receiving member attached to one side of the head band receiving member, said hook receiving mem- 40 her being U-shaped in cross-section both longitudinally and transversely, and a hook pivoted in said hook receiving member adjacent the juncture of the longitudinal and transverse closed edges thereof and extending toward the open side of said hook receiving member, inwardly extending spring jaws formed in said hook receiving member near juncture of the closed transverse edge and the open edges thereof, said hook in its open position being located on one side of the spring jaws and in its closed position on the other side thereof, and the free end of said hook engaging the longitudinal closed edge of said hook receiving member at a point remote from the pivot of said hook when the hook is in the closed position.

CHARLES FISCHER.
