July 9, 1935. R. MALCOM GOGGLE FASTENING MEANS Filed. May 31, 1934 \NQM Patented July 9, 1935 UNITED I STAT Es PATENT OFFICE 9 Claims.

My invention relates to means whereby the eyecups of goggles are adjustably secured together thereby adapting the goggles to the different facial contours and the variations in eye-positions of I different individuals.

The invention has for its object the provision of a construction that is simple in design and which may be easily adjusted by the user without need of tools or special skill; a construction which will maintain its adjusted positions; a considerable latitude or range of adjustmentsbeing possible.

The objects and advantages of my invention will be readily comprehended from the following detailed description of the exemplifications of my invention disclosed in the accompanying drawing, wherein-- I Figure 1 is a front elevation of a goggle with my improved fastening means; the head straps being omitted. I

My invention relates more especially to goggles intended for commercial purposes, namely in industries where the eyes of workmen require protection from flying particles or from the action of certain light raysand the invention exists in the means whereby the eye-cups of the goggle are adjustably fastened together by a flexible nosebridge. r

As the facial contours and positions of eyes of 7 different users vary at times to a considerable degree, it is essential to provide eye-cup fastening means which may be readily adjusted .to hold the two eye-cups in proper position without, however, placing them under a contracting tension which would subject the wearer to an uncomfortable pressure and injurious strains;

In the particular exemplifications of the invention, the eye-cups Ill, [B of the goggle are made of a rigid material, such as bakelite, and preferably shaped to completely enclose the eye-socket; the inner perimeters of the eye-cups being formed to fit the contour of the face about the eyes. The walls of the eye-cups are preferably comparatively thick as shown to withstand more or less rough usage by workmen.

In goggles of this character the lenses II, II are generally removably held in place by the lens- 10 rings l2 which are threaded onto the cup walls or have lug and groove interlocking relation; the eye-cup walls being enlarged beyond the applied position of the lens'holding rings so as to provide a shoulder below the ring asat l3. The lens I l is intended to rest on the annular perimeter of the eye-cup where it is held by the flange of the lens ring l2 in the usual manner. v

The inner or nose side of each eye-'cup,fat a point just beneath the plane ofthe shoulder I3, is provided with an opening [4 extending entirely through the wall; and the eye-cup wall at a point coincident with opening I4 is provided with a slot l5 extending in a direction transversely of the wall from the lens seating perimeter to a point preferably slightly beyond the opening I4 as shown at l6. V

The inner end it of the slot H5 is intermediate of the inner and outer surfaces of the eye-cup; that is to say, this end of the slot is surrounded on both sides by the eye-cup wall; while the upper or outer end of the slot will be exposed when the lense holding ring I2 is removed.

The openings M in the side walls of the eyecups are of size sufficient to permit passage of the well known type of ball-chain, consisting of a suitable flexible cord or wire IT on which the small balls it are threaded and arranged in comparatively close relation, with the end balls firmly secured to the wire or cord H in the usual well known manner. The flexible ball-chain is of the conventional type found in the open market.

Thisball-chain forms a flexible nose piece for yieldingly connecting the two eye-cups together, and in order to prevent injury to the nose of the wearer the chain is preferably provided with a soft yieldablecovering or small rubber tubing 18 of length corresponding to the minimum spacing of the eye-cups but of sufficient length to cover the portion which passes over the bridge of the nose.

The slot Iii, in the side wall of each eye-cup, is shown provided with a small locking member 20 which is slidably mounted in place and is adapted to provide locking or holding engagement with the ball-chain.

The locking member employed in Figure 2 is shown in perspective in Figure 3 and consists of a thin, preferably metal, strip having one end bent back as shown at 2I so as to receive the reduced outer end portion 22 of the wall of the eye-cup between the finger engaging end ZI and the main portion of member 20, as shown in Figure 2.

The other end of slide piece or member 26 is provided with a passage 23 which in this specific embodiment is in the nature of a notch or slot of width less than the diameters of the spherical portions or balls I8 of the chain. It will be understood that the member 20 consists of a thin metal piece which will readily fit between two adjacent balls I8 as shown in Figure 2.

The lens seating perimeter of the eye-cup, coincident with the slot I5, is preferably notched or recessed to receive the curled or bent portion 24 of thelocking member 20 and permit said portion to be flush with the lens-seat.

The notched or slotted end of the member 26 isshown preferably slightly rounded to ensure the easy passage of the member 26 across the chain.

Before the lenses I I and the lens holding rings are put into place, the length of the chain or nose piece is regulated to, maintain the two eye-cups in proper position and spaced relation in keeping with the eye spacing of the wearer.

This adjustment is accomplished by inserting the ends of the chain, preferably to equal distances, through the holes I4, I4 in the eye-cup walls and then sliding the locking members or pieces 20 into the slot I5 so the end provided with the slot or passage 23 intersects the chain and passes into the closed end I6 of the slot I5; while the bent end 2I laps the inner portion 22 of the eye-cup wall. The lenses I I are then placed onto the perimeter or seat of the eye-cup and the lens rings I2 put into place. It is apparent from the construction shown and described, the inner or notched end of the locking member will be disposed within'the eye-cup wall; while the outer or bent end will have the portion 22 of the eyecup wall on one side of the main portion of member 20 and the lens holding ring I2 on the opposite side and as a result the lock member 29 will be completely enclosed or walled in, making it impossible to distort or bend the member 2!) although it is made of a very thin piece of metal. At the same time it will be seen that when the lens and the lens holding ring are in place, the

locking member 20 must be in looking position and. be held there against any possible movement. As a result, a secure fastening for the eye-cups is provided and the goggle maintained in its adjusted position, which, however, may be readily altered by simply removing a lens and lens holding ring and then sliding the lock member in the direction of the lens-seat until the notched end of member 26 clears the chain, permitting the latter to be moved farther into or out of the eye-cup.

In Figures 4 and 5 I illustrate a modification of the locking member 2t! which is identical with member 20 except that the bent portion 25 is somewhat longer than the portion 2I of member 20, and this portion 25 is curled toward the bending the short end 25 as shown at 26, a better finger grasping portion is provided; the locking member being of a. quite thin piece of metal, with preferably a sufficient amount of resiliency to effect the binding or gripping relation with the cup wall portion 22.

In Figures 6 and 7, a further modification of the locking member is shown; the construction of the eye-cups for receiving the locking member being the same as that heretofore described; being provided with the chain receiving passage or hole I4 and the wall at a point coincident with the hole having the transverse slot I5 for receiving one leg or side 21 of locking member 28, while the other leg 29 extends snugly against the side wall and within the eye-cup, with the cup wall portion 22 disposed between the two legs 21 and 29.

The locking member 28 is shown with the end of leg 2'! notched or slotted at 30 in a manner similar to that shown in Figiu'e 3; the notch or slot being of less width than the diameters of the enlarged or spherica1 portions of the nose piece.

The other side or leg 29 is shown provided with a key-hole type of passage 3|; with the narrow or lower portion of the passage in alignment with the lower or closed end of the notch or slot 30; while the large end of the passage 3| is in a plane slightly above the open end of slot 30. In order that this may be accomplished, the leg or side 29 is made longer than the side or leg 21. The upper or large end of the passage 3! is made large enough to permit passage of the spherical portions or balls I8 of the chain therethrough, while the lower narrower end of the passage, like that of the passage 30, is of less width than the diameters of the balls of the chain and will merely receive the cord portion I'I. As a result, a double locking engagement with the nose piece or chain is provided.

Like in the previously described constructions, the lock member 28, in order to permit adjustment of the nose-piece, must be moved from its normal or the operative position shown in Figure 6 by sliding member 28 outwardly in the direction of the lens after the lens holding ring I2 and the lens II have been removed; the member 28 being slid outwardly a distance sufficient to position the large end of passage 3| in alignment with the hole or passage I4 in the side wall of the eye-cup. Such positioning will also place the open end of the slot or notch 3!! in proper position to permit free movement of the chain.

It is apparent from the various embodiments of the invention that the locking members will be held against movement as soon as the lenses and the lens holding rings have been put into place; and that these lock members may be of very thin sheet metal as flexing or bending of the members, while in use, will be impossible because the main legs or sides ride into the closed ends I6 of the transverse slots within the walls of the eye-cups and hence are not only reenforced by the eye-cup walls but are also backed up or reenforced by the lens holding rings.

With the main portion of the locking member arranged within the side wall of the eye-cup, interference with easy access to the inner surface of the lens is obviated; the construction permitting the entire inner surface of the lens to be properly cleaned or wiped.

My invention provides a simple and very efficient adjustable fastening means for the flexible nose piece of the goggle and while I have disclosed what are believed to be the best embodiments of the invention, other modifications are possible and may be made without, however, departing from the spirit of my invention which has been described. in terms employed for purposes of description and not as terms of limitation.
