3 Claims.

This invention relates in general to an eye protector adapted to be used by mechanics and other persons to protect theirv eyes from dirt, and flying particlesA as well as air currents andli'ght, and to provide ventilation when in use.

One of the principal objects of the'invention is` which the cups including the fastening threads and the ventilation openings may be cast or molded in making the cup.

Other objects of the invention will appear hereinafter, the preferred construction being illustratcd in the accompanying drawing.

In the drawing, Fig. 1 is a front view of a pair of goggles constructed in accordance with this invention;

Fig. 2 is a section taken on the line 2-2 of Fig. 1; and Fig. 3 is a section taken on the line 3-3 of Fig. 2.

In the formation of goggles it is necessary to provide ventilation in the eye cups to prevent the lenses from fogging and the Ventilating holes should be so protected as to prevent direct rays of light from passing through the eye cups to interfere with the vision and to also exclude fine particles of dirt. dust and the like, which would be very objectionable. The present invention overcomes these objections by providing a. number of opposite perforations which are covered by the rim of the lens retaining cap or ring yet affording free circulation of air therethrough in a number of indirect paths which are directed toward each other and not toward the eye of a wearer.

Referring now more particularly to the drawing, a pair of eye cups 6, each formed with a projection 7 adjacent the nose and a side extension 8 to engage the side of the face are adjustably connected by a chain 9 having a exible tubular cover 10 and secured through each cup adjacent the projection 7 by an cyelet staple 1l. To adjust the cups toward or trom each other they arc relatively turned, twisting the chain 9 to contract or extend it in the cover 10.

At the outer end of each cup is a tubular porter. 2 14) non 12 having 'a reduction shoulder 13 at the outer edge to provideV a cylindrical shell in the outer surface of which are raised threads 14, opposite diametric portions of which are omitted, forming spaces as indicated at 15 in Fig. 3, so thatA in molding these parts the two opposite molds can be separated in forming the cup, without distorting the threads.

In the wall of the cup at the threaded portion thereof, preferably through the innermost thread or threads, are a number of ventilation openings 16 extending substantially parallel to each otherl and transversely through the cup as shown more clearly in Fig. 3. The threads being raised from the surface of the cup and the Ventilating holes extending through the innermost thread provide means for admitting suflicient circulation of air if the holes through the threads are not tightly covered.

One or more glasses or lenses 17 and 18, plain or colored, may be applied over the end of the cup where they are held tightly in place by a removable cap 19 having a flange 20 to engage and hold the lenses and having a rim with projecting internal threads 21 adapted to engage with the threads 14 on the cup and with a cut away edge 22 at the inside of the rim extending to the threads 21 to slightly increase the space between said rim and surface of the cup and which leads to the Ventilating holes 16. When the cap or ring is threaded tightly in place a. space is left all around the inner edge or rim of the cap communicating with the holes through the innermost thread on the cup member, thus providing unobstructed irregular passages for ventilation and for excluding light rays and dirt or other foreign matter from the interior of the cup members. It will be understood, however, that as the external threads on the cup and internal threads on the ring are raised above the adjoining surface or surfaces an annular space will be left between the rim or inner portion of the ring and surface of the cup the depth of the thread or threads, andconsequently in some instances it is not necessary to bevel the inner side of the rim as hereinbefore stated. The openings may be through the wall of the cup at the inner side of the threads and still be covered by the overlying rim of the cap, the important feature of construction being the raised threads on the interengaging parts which provide that the rim beyond the threads on thc ring is spaced from the surface of the cup forming an annular space leading to the ventilating holes with the rim overlying said holes to protect the goggles from direct rays lof light and from particlesentering the holes.

To hold the goggles upon the head of a wearer, perforated projections or eyelets are cast or formed on the outsides of the cups 6 to which the fastening tapes 26 are secured, the tapes being connected by a buckle or they may be tied together in any desired manner. As these goggles are form or face tting they are held tightly about the eyes by the tapes.

With this construction full ventilation may be provided without danger of admitting light, and without danger of the openings becoming clogged. If one or more of them should become stopped up it is easily cleaned by removing the cap and inserting a sharp instrument through the clogged opening.v If a single lens is used a washer may be provided either at the inside or the outside of Vsaid lens whichvis held in place by the cap without closing the passageways formed between the cap and the cup, and of course raised threads on the cup also provide fc.- a variable adjustment of the ring on the cup in accommodate glasses or lenses of diner-entthicknesses. A neat appearing goggle is thus provided entirelyifree from visible ventilation openings.

I claim:

1. A pair of goggles comprising guard members or cups adapted to t over the eyes and each having external threads at its outer edge raisedv above the adjoining surface or plain circumference of the cup, Ventilating holes extending through the sides of the cup at the threads, and a ring for retaining a glass in place having internal threads and a rim projecting beyond said threads, the internal threads engaging the threads on the cup, whereby an annular air space is provided between the rim and plain circumference of the cup communicating ith the aforesaid Ventilating holes.

2. A pair of goggles comprising guard members or cups adapted to fit over the eyes and each having external threads at its outer edge raised above the adjoining surface or plain circumference of the cup, Ventilating holes extending through the sides of the cup and threads, and a ring for retaining a glass' in place having in ternal threads and a rim projecting beyond the engaging portion of said threads, the internal threads engaging the threads on the cup, whereby an annular air space is provided between the projecting portion of the rim and plain circumference of the cup communicating with the aforesaid ventilating holes passing through the threads and sides of the cup.

3. A pair of goggles comprising guard members or cups adapted to fit over the eyes and each having external threads at its outer edge pro-Y jecting above the adjoining surface or plain circumference of the cup, Ventilating holes extending through the sides of the cup and threadsI and a ringfor retaining the glass in place having raised internal threads and a rim projecting beyond said threads, the raised internal threads engaging the threads on the cup, whereby an annular air space is provided between the rim and plain circumference of the cup communicating with the aforesaid Ventilating holes passing through the threads and sides of the cup.
