" Renewed June 4, 1936 'l'his invention relates to eye protective devices; and it is among the objects of the invention to provide a device havingvgoggle cups formed to effectively cover theeyes and capable ofbeing 5 quickly adapted to any size head and being easily put on or off. Other objects and advantages will appear as thewdescription proceeds.

To the accomplishment of the foregoing and" related ends, the invention then, comprisesthe lo ifeatures hereinafterffully described and particularly pointed out inrthe claims, the following description and the annexed drawing setting forth I indetail certainillustrative embodiments of the the invention may be employed. In said annexed drawing: a a f Fig. 1 is a perspective view 0f anembodiment of the invention; Fig. 2, isa s'ideelevati'onal view,

. parts beingomitt'ed; Figs. 3 and 4 are detail elevations: Fig.25 isa reduced scaleplan detail; Fig. 6 is a fragmentary sectional view-of a'modiflcation; and Figs. 7 and 8 are elevationaldetails of i Y w stretching up to the limit of the extended length i the same. :9

Referring ,more-lsparticularly to the drawing, i there is shown a protective goggle comprising.

gogglecups 2,v a nose-bridge Sand holding means 4. The goggle cups are formed of suitably light 1 materiaL -aridwhileinsomecases metallic shells may be used, generally synthetic resin molded shells are preferable. Each goggle a, cup is equippedwith a-glassiat its front, the glass being held by any suitable means,, as, for instance a.

screwcap 6, and at the rear thecup, has its edges I superand sub-orbital portions ofthe face.

Means for ventilation is desirably provided, as-ior instance screens I which maybe set, in the outer quadrant. If desired, perforations may be addiin thekcup body above and;

tionally providedbelow. At the outer rear edge ofeach cup, the

holding means 4 comes into engagement, =,As g V coilspring means 3a, Fig. l, or other features, in some instances it may include a section of take-up shown more in detail in Fig. 2, this means involves 55 between beads. and having ears Ill, H, which may reclai s. (ore-114) t v invention,'these beingyindicative however, of but a few of the various ways in which the principle of a chain 8. of suitable form, preferablyas dumbbells or small balls, or beadsheld serially togetherandallowingsome internal take-up movement from bead tobead such movement however, I U being limited both as to extension and compres be bent down sufliciently tightly to prevent dis engagement of the chain from out of the notch. Such lug maybe rigid on the cup or preferably may havehinge-like connection onto a bail 9a of the outer rear end of the cup. As seen, such fix ture allows of g the chain being inserted at any selected position, that is at any link desired, and in a device of size-range required the surplus links for anyadjustment need not be many inany case, and are unnoticeable. Associated with the chain is a take-upspring I2, providing suflicient resiliencyto yield and allow easy removal, or when the device is in place serving to hold it sufficient tautly to prevent accidental displacement. In the form shown, the spring comprises a coil section extending through a partial arc,of the band 4, and

' being fastened at its ends to the chain 8 by having the ends of the spring wire sufllciently tightly clampeddowmbetween beads. By'locking the spring in place when'the chain 8 is held in a compressed position, that is with the links brought together in closest positions,,the spring 12 as finally locked to the chainwill readily allow of what flattened and having suflicient resiliency to M snap over the, ears [0, H on the goggle cup. The

same, resiliency allows the ring 14 to be sprung loose when desired, by applying suflicient pressure. a r 1 p While the nose bridge! between the goggle cups may be of varied construction, including takeup chain 8a, 6, like the'main holding chain described. Such chain may engage regulably in each goggle cup, so as to allow of lengthening or shortening asdesired. For instance, the end of the chain may extend through a key-hole-like slot in the goggle cup, the enlarged portion l5 of i the slot being of size to just allow passage of the chain, while the narrow or slotted portion I6 of the key-hole is of a size to just receive the narrow portions of the links or the wires between beads. By setting the chain to the length desired between the goggle cups, and pushing the narrowed portion back into the slot 48, and then putting the cap 6 on in place, the edge of the latter covers the enlargement I of the key-hole slot and finally prevents any disengagement of the chain from its adjusted position. A guard ll of tubular form, for instance a tube of rubber, celluloid or other desired material, may be applied over the chain as a further refinement.

Since eye protective devices generally have to be worn for hours at a time, and under uncomfortable conditions of exposure to heat, flying particles, etc., it is of particular importance that a device beaccurately fitting and comfortable to the wearer. The present invention makes possible a realization of highly effective placement over the eyes, and yet without discomfort even on long continued wearing. In the event also that the device is to be used by others, quick adjustment to the precise head size may be quickly had.

Other modes of applying the principle of the invention may be employed, change being made as regards the details described, providing the means stated in any of the following claims, or the equivalent of such, be employed.

I therefore particularly point out and distinctly claim as my invention:-

1. An eye protective device, comprising goggle cups'and holding-means for holding the same in place, including a chain, a tubular cover therefor, and snap-securing means for anchoring the cover.

2. An eye protective device, comprising goggle cups and holding-means for holding the same in place, including a chain, a tubular cover therefor, and a resilient snap for anchoring the coverend.

3. An eye protective device, comprising goggle cups, holding-means for holding the same in place, including a chain, slotted lugs on each goggle cup for engaging narrowed link portions of the chain, bent-down ears for locking the chain in place, a coil spring surrounding said chain for at least part of its length, a tubular cover for said chain and spring, and snap-securing means for anchoring the cover.

4. An eye protective device,'comprising goggle cups and holding-means for holding the same in place, including a chain, a slotted lug at the outer rear end of each cup for receiving a narrowed portion of the chain, ears for locking the chain against displacement from the slot, a tubular cover for the chain, and a resilient ring on each .end of the tubular cover for snapping over said ears.
