OPHTHALMI C MOUNT ING Filed March 21, 1951 vi EL I INVENTOR 2 5 BY eaz gelz izllzy Patented May 24, 1932 UNITED STATES PATENT OFFICE GEORGE L. TULLY, OF SOUTHBBIDGE, MASSACHUSETTS, ASBIGNOR TO AMERICAN OP- TICAL COMPANY, OF SOUTHBBIDGE, .MASSACHUSETTS, A VOLUNTARY ASSOCIATION OF MASSACHUSETTS OPHTHALMIC MOUNTING Application filed larch 21, 1931. Serial No. 524,303.
This invention relates to improvements in connecting or securing means and has particular reference to improved means for uniting the parts of an ophthalmic mountmg.
The principal object of the invention is to provide an improved connection or securing device for uniting the parts of an ophthalmic mounting wherein the said parts may be quickly interchanged or adjusted.
Another object of the invention is to provide improved means for connecting the lens holding members of an opthalmic mounting wherein the distance between said members may be quickly and easily adjusted to fit the facial requirements of the wearer.
Another object is to provide an improved adjustable bridge for an ophthalmic mounting and improved means of attaching the said bridge to the lens holding members of said mounting.
Another object is to provide improved means for securing the attaching means against displacement and consequently preventing the connecting means from becoming loose or detached from the lens holding members during the use of the ophthalmic mounting.
Another object is to provide a connecting or securing device which is simple and efiicient in its nature and operation and which may be quickly and economically manufactured. o
Other objects and-advantages of the invention will be apparent from the following description taken in connection with the accompanying drawings and it will be understood that many changes may be made in the details of construction and-arrangement of parts without departing from the spirit of the invention as expressed in the accompanying claims. I therefore do not wish to be limited to the exact details shown and described as the preferred forms only have been shown by way of illustration.
Referring to the drawings; Fig. I is a front elevation of an opthalmic mounting embodying the invention showing a portion thereof in section; 1
Fig. II is a perspective view of one of the .requirements of different individuals.

Fig. III is an enlarged fragmentary sec tional view taken on line IIIIII of Fig. II;
Fig. IV'is a sectional view taken on line IVIV of Fig. I showing the parts disunited; A
Fig. V is a view similar to Fig. III, showing a modified form of the invention;
' Fig. VI is a fragmentary view of the interiorof the. lens holding member shown in Fig. V showing a face view of the connecting means; 1
Fig. VII is a fragmentary perspective view of another modified form of the invention; Fig. VIII is a perspective view of the connecting means shown in Fig. VII; and
Fig. IX is a fragmentar sectional view of a further modification of t e invention.
With certain types of ophthalmic mountings particularly eye protectors and goggles it is necessary that the mounting be so formed that the distance between the lens holding members may be adjusted to fit the faciIal 11 prior art mountings where attempts have been made to accomplish this result it has been found diflicult top'roduce a connection that will hold the bridge member securely in position and yet be so constructed that the distance between the lens holding members maybe easily and quickly adjusted.
It 'is therefore the prime object of my invention to provide a simple and eflicient connection of the bridge means to the lens holding members of an ophthalmic mounting wherein the saidbridging means may be easily and quickly adjustedto the requirements of the wearer and be held securely in the adjusted position during the use of the mounting.
Referring more particularly to the drawings in which similar characters of reference designate corresponding parts throughout the several views the device to which the invention is shown applied comprises a pair of eyecup members 1 which are formed with a face contacting edge 2 shaped to the contour of the face and a threaded portion 3 to which a threaded lens retaining ring 4 is attached to secure a protection lens 5 within the eyecup.
The eyecup members 1 are connected centrally by a bridge member 6 and are provided with a suitable head band 7 to hold the mounting on the faceof the wearer.
A perforated shield member 8 is secured over an opening in the side of the eyecup 1 to provide the necessary ventilation.
The receding construction is of a commonly rnown goggle or eye protector and may be varied at will as may seem necessary to obtain the best results as the improved connecting or securing device embodying the invention may be used with many different constructions.
The bridging member 6 shown in Figures I to VII inclusive is flexible and is formed of a plurality of ball members 9 connected in spaced relation by a series of link members 10. The bridge. member is covered by a tubular member 11 which may be formed of a non inflammable substance, rubber or other soft protective material.
The connection of the bridge member 6 to the eyecups is formed by piercing the side Walls of the eyecups to form an opening 12 t-herethrough in which the ends of the bridge member 6 are secured. The securing means as shown in Figures I to IV inclusive is shown in Figures formed of a plate member 13 pivoted at 14 to the interior of the eyecup. The plate member is provided with a slot 15 which straddles a link member 10 between the ball members 9 and in this manner securely attaches the end of the bridge member to the eyecup. When the plate member 13 is in locked position on the link member 10 as shown in Figures II and III and the lens 5-has been secured in the eyecup, the end 16 of the plate 13 opposite the pivot connection 14: engages the under surface of the lens 5 and is in this manner held against displacement. This prevents the possible loosening and detaching of the bridge member during the use of the mounting.
An up turned portion 17 formed on the end 16 provides a thumb piece by which the plate 13 can be easily moved on its pivot.
When it is desired to interchange or adjust the bridge member 6 the retaining ring and lens 5 are removed from the eyecup and the plate member 13 is then moved outwardly on its pivot 14 as shown in Fig. IV. This permits the end of the bridge member to be adjusted or detached from the eyecup.
Both'ends of the bridge member 6 can be removable from the eyecups if desired or one end can be permanently attached to one of said eyecups.
A slight modification of the invention is V and VI wherein the be detached and adjustbridge member can the lens 5. This 1s aced without disturbing complished by pivotally mounting a plate member 18 so that it is free to rotate without engaging the lens 5. In this instance the plate member 18 is provided with a projection 19 which when the plate member is in locked position with the bridge 6 extends into a recess 20 in the eyecup and holds the plate member against displacement during the use of the mounting. The projection 19 is held in the recess 20 by the resiliency of the plate member 18. A lip 21 is formed on the plate member 18 adjacent the projection 19 so that the said projection can be lifted out of the recess 20 when it is desired to move the said plate member to interchange or adjust the length of the bridge.
Another modification is shown in Figures VII and VIII wherein a split washer member 22 is employed instead of the pivoted plate members 13 and 18. When the desired length of bridge is obtained the split washer 22 is forced over the link member 10 between the ball members 9 and thereby secures the end of the bridge member to the eyecup. The washer functions similarly to the plate members 13 and 18 but is not'secured to the eyecup.
In Fig. IX there is shown a further modification wherein a chain bridge member 23 is used instead of the ball and link arrangement referred to above. In this instance the slot 15 in the plate member 13 straddles one of the link members 24: adjacent the end of the bridge and the normally related link member 25 at the end of the bridge engages with the side of the plate member and locks the said bridge in the eyecup.
The plate 13 may also be formed with a projecting lug member 26 adjacent the slot 15 which when the chain bridge member 23 is used can be extended within the link member 24 or 25 to lock the bridge member to the eyecup. With this type of plate member either the ball and link bridge 6 or chain bridge member 23 can be used and the said chain bridge can .be attached to the eyecup through the use of the slot 15 or projecting lug 26 as desired.
From the foregoing it will be seen that I have provided simple, eflicient and economical means of carrying out .the objects of the invention, particularly in providing extremel v simple and efficient means for allowing the bridge member to be easily andquickly adjusted and for looking it in adjusted posi-' tion so that it cannot become disengaged while the mounting is in use.
