The bridge is constructed description of the embodiment illustratedin the 95 in two parts, each part forming a portion of the drawing in which: cross piece and one leg ofthe bridge. One of Fig. 1 is a front elevation of a pair of goggles the parts constitutes a shank, and the other part constructed in accordance with my invention; has a chuck formed thereon which is adapted to Fig. 2 is a plan of the same; receive and clamp the shank of the 'other part. Fig. 3 is an enlarged fragmentary sectionillus- 100 The two parts are .separable and by virtue of trating the bridge member and its connection to the construction, the bridge is adjustable to the eyecup; vary the .distance between the eyecups. The Fig. 4 is an enlarged fragmentary plan partly chuck comprises a plurality of jaws which are in section taken. on the line 4 4 of Fig. 3, and tapered on their outer surface. The jaws are showing the bearing socket in the eyecup for the .pressed into clamping position by an internally legcf the bridge member; threaded sleeve Vwhich fits over the jaws. A Fig. 5 is an enlarged fragmentary end elevastop shoulder is provided on the chuck which tion; y limits the'movement of this internally threaded Fig. 6 is an enlarged fragmentary sectional sleeve. By-providing this stop shoulder, the dielevation; i

ber and are identical with the exceptionthatV they are relatively reversed. Each eyecup is split transversely at the temple end andv a looking means is provided at the split. The locking means provided is the same for each eyecup and includes a link 2 which is pivotally secured Itoy the eyecup. The link is curvedto correspond with thatportion of the eyecup over which it is adapted to lie. At one end of the link, there is formed a hinge 3 which is pivoted to a lug 4 formd on a plate 5 which is secured to the inner surface of the eyecup, the lug extending through the eyecup. The link is shaped to fitisnugly against the outer surface of the eyecupv'and it is provided with an overlapping portion 6 which overlapsthe bezel of the eyecup, andwhen lthe eyecup is closed, the link overlies the transverse split therein.

On the eyecup at one side of the` split therein, opposite to that to which the link is pivoted, there is formed an elevated portion '7.v Through this elevated portion of the eyecup av pin 8 extends, the pin 8 extending laterally from, the outer surface of the eyecup and being secured to the eyecup. On the pin, there is rotatably mounted a locking member 9 which is frustc-conical in shape having diametrically opposedV surfaces planed to form a pair of parallel sides 10, making the base of the locking member oblong in cross section. The locking member is secured in place on the pin 8 by a cap 11 formed on the top ofthe pin and overhanging the end of the locking member. The distance between the parallel sidesY of the locking member is equal to the width of the extension 7 formed on the eyecup and from which the locking member extends.

The link 2 has a slot 12 formed therethrough. The slot 12 is of sufficient width and length to receive the extension '7 formed on the eyecup, and'to receive the locking member 9 when the locking member is positioned with its major transverse axis, or the parallel sides thereof, parallel to the longitudinal axis of the slot. The slot is of less width, however, than the major axis of the locking member. When the locking member is positioned with the-major axis parallel to the longitudinal axis` of the slot andY the eyecup is held in the closed position, the link may be swung about itshinge connection tc the eyecup to lie against the eyecup, the locking member passing through the slotin the hinge. When the hinge is in the closed position and the locking member is rotated about the pin so that this major axis is transverse to the longitudinal axis of the slot, the link is securely locked in the closed position.

To prevent accidental opening of the eyecup during service, the pin extending from the extension 7 on the eyecup is provided with a transverse hole 13. The looking-member is also provided with a transverse hole 14 which passes through the parallel sides of the locking member. The transverse hole 13 through the pin lies in the plane including the longitudinal axis of the slot formed through the link 2. When the locking member is turned so that its major transverse axis is perpendicular to the longitudinal axis of the slot, in which position the link is locked over the extension 7 on the eyecup, the hole 13 through the pin and the hole 14 through the locking member are in alignment, and the attachment for the head band may pass through these holes thereby securing the head band to the goggle and at the same time, securing the locking member in the looked position.

rlhe eyecups are formed from sheet metal so that they can ex in their own plane. Asclearly shown in Fig. 8, the eyecups taper inwardly from the bezel thereof. For each eyecup. there is provided a cushion 15. Each cushion has an outwardly extending lip 16 which is adapted to extend into the eyecup. The outwardly extending lip ofthe cushion is also tapered, the taper of the lip being complementary to the taper of the eyecup.V Secured to the inner circumferential surface of the lip of the cushion, there is a flexible sheet metal reinforcing band .17. When in position in the eyecup, and the eyecup is closed over the lip of the cushion, the inner circumferential surface of thexeyecup engages the outer circumferential surface of the lip of the cushion. The reinforcing band 17 .prevents the lip of the cushion from flexing within the eyecup, and the taper .of the eyecupfand the lip of the cushion prevent relative movement of the eyecup and cushion in a direction. to withdraw the lip of the cushion from the eyecup. The cushion abutting against the edge of they eyecup serves to prevent outward axial movement of the cushion. Byopening the eyecup and flexing the eyecup in its own piane, the cushion may be readily removed and replaced. y

The two eyecups are united by a bridge member which is constructed in two parts. Each part of thebridge member forms a part of the cross-piece and one leg 18 thereof. One of the parts has a chuck formed thereon which includes a plurality of jaws 19. The jaws are tapered longitudinally and are threaded on their outer surfaces. The threads on the outer, surface ofthe jaws of the chuck are engaged by an internally threaded cup-shaped sleeve 20. As vthe sleeve is threaded onto the jaws, the taper of the jaws causes the -jaws to be moved towards `,the axial center of the? chuck and as Vthe sleeve'Y is moved in the opposite direction the jaws return to their original position under their own resiliency. At the end of the jaws, there is a shoulder 21 formed on the bridge member. This shoulder acts as a stop shoulder to limit the movement of the sleeve.. `In limiting the movement of the sleeve, the shoulder also determines the direction which the sleeve must be turned in order to loosen or tighten the. chuck. Thus, when the'vsleeve is abutting against. the shoulder, the chuck is in its clamping position and exerting its maximum clamping effect. To loosen the chuck, the sleeve mustl be rotated so that the coaction of ,the threads will be to move the sleeve away from the shoulder. Y, f

The chuck is adapted to clampthat portion 22 of the other part ofthe bridge member .which forms part of the'cross-piece thereof andwhich constitutes a shank. When the chuck is loosened, the shank may be inserted between the jaws yof the chuck through an opening in the end of the sleeve 20 and when the sleeve is tightened on the jaws, the shank is firmly clamped between the jaws. It is obvious that the shank may be inserted in the chuck to a lesser or greater distance depending upon the desired distance between the eyecups.y

The bridge member is secured to the leyecups through the legs 18 thereof which are received in bearing sockets 23 secured to and extending into the eyecups. Each bearing socket is provided with an arm 24 which is riveted to the outer circumferential surface of the eyecup. Each of the legs of the bridge member is bifurcated at its end to form a resilient end section. These resilient end sections are provided with a shoulder 25 which, when the leg is in position in the bearing socket, is adapted to engage the end of the bearing socket. The leg is also provided with an integral collar 26 which is adapted to abut against the upper end of the bearing socket to limit the inward movement of the leg. Intermediate the end of the leg of the bridge, there is a pin 2'7 extending laterally from the surface of the leg. The inner wall of the bearing socket is provided with communicating longitudinal and circumferential slots 28 and 29 which are adapted to receive the pin 27. The circumferential slot 29 terminates at one end in alignment with the side wall of the longitudinal slot 28. With this construction, when it is desired to remove the eyecup from the bridge member, the pin may be aligned with the longitudinal slot by rotating rthe eyecup with respect to the leg of the bridge member until the pin Vabuts against the end of the circumferential slot, in which position it will be in alignment with the longitudinal slot. The end ofthe leg member may then be pressed so as to release the shoulder 25 from the lower edge of the bearing socket and the leg may be withdrawn from the bearing socket.

It is obvious that various changes may be made in the details of the embodiment illustrated in the drawing and above particularly described within the principle and scope of our invention as expressed in the appended claims.
