SPECIFICATION formingpart of Letters Patent No. 731,820, dated June 23, 1903. Application filed May 23, 1902. $eria1 No. 108,681- (No model.)

ToLaZZ whom it may concern:

Be it known that I, WILLIAME. STEVENS, a citizen of the United States, residing at Newark, in the county of Essex and State of N ew J ersey,have invented certain new and useful Improvements in a Lorgnette and Opera-Glass Combined 3 and I do hereby declare the following to be a full, clear, and exact description of'the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and

to letters of reference marked thereon, which form a part of this specification.

The objects of this invention are to provide a combined lorgnette and opera-glass which will be of more simple construction, of

lighter weight, more convenient and easy of I operation, and to enablethe lens-frames to unfold automatically when released, so that the parts will automatically assume a positionconvenient and proper for use, and to secure other advantages and results, some of which may be referred to hereinafter in connection with the description of the working parts. i

The invention consists. in the improved combined lorgnette and opera-glass and in the arrangementsand combinations of parts ofthe same allsubstantially as will be hereinafter set forth and finally embraced in the clauses of the claim.

Referringtothe accompanying drawings,

in which like letters of reference indicate for use.

corresponding parts in each of the several figures, Figure l is a top view or plan of the device open and ready for use. Fig. 2 is a similar view showing the lens-frames folded ready to be inserted in the handled case. Fig. 3 is a sectional view showing the same when the said lens-frames are foldedtogether view of the device when the parts are opened Fig. 5 is a section taken on line so of Fig. 4 in the direction of the arrow, and Fig. 6, is a sectional VlQW on the same line looking in the opposite direction from that indicated by the said arrow. Fig. 7 is a detail section at line 2, Fig. 2. Fig. 8 is a detail section showing the arrangement of the adjusting-screw and nut, and Fig. 9 is a deare adapted to turn.

Fig. tie a side tail view of the catch for holding the folded lens-frame in the case.

In carrying out my invention I employ a handled case a, which is of ornamental shape and .open at one side to receive the folded lens-frames and at its top is provided with a pivot 1), upon which the said lens-frames At the opposite side of the opening in said case from the pivot 22 the said case is provided with a catch 0, substantially such as is commonly employed in lorgnettes, the said catch being controlled by a spring d, Fig. 9, and adapted to be operated by a finger-piece e. The parts'are so arranged that bypushing the said finger-piece lengthwise of the handle the catch will be released from the folded frames that the latter will be enabled to move outwardly under the influence of a spring hereinafter described.

Around the pivot 19 and between the cars a a. of the case is arranged a drum f, within which is a coiled spring 9, Fig. 7, the said spring being attached to said drum'and tothe pivot and being normally under tension, so that when released the spring will turn said drum and the parts carried thereby to their open or outward position, the movements of the drum being limited, however, by means of a stop-bridge h, extending from one ear to the other, the said bridge serving also as a partial inclosure for the drum, whereby it is to some extent concealed from view and a better finish given to the casing. Attached to the said drum f is'an arm or bar '6, upon which the lens-frames 9j and k are pivoted. Said arm is preferably in sections z'"t' one section being adapted to slide on the other telescopically to enable the lens to be focused to suit the vision. The said arm or bar is longitudinally slotted to receive an adj Listing-screw m, the nut 42 of which lies in a transverse slot 0 of the arm-section i, as shown in Fig. 4, wherebywhen the nut 91. isturned the screw and the sliding member of the arm attached to the said screwm will be given a longitudinal movement with relation to the fixed member of the bar. Near the base of the arm 1' or its point of connection with the drum are pivoted the objective-lens frames j, which are pivoted at 19, Fig. 1, so as to fold against the opposite sides of the bar '5 when pressed by the hand, and when released from the hand or when released by withdrawal from the case to open automatically, so that the said frame will stand in a plane at right angles or approximately at right angles with the said arm or bar, the frames being each provided with a stop q for limiting the said frames when moved under the power of the springs r on the hinge-pinsp at such right-angular position. Upon the sliding member 7? of the sectional arm tare likewise pivoted the eyepiecelens frames 70 7a, which are also controlled by springs and are adapted to fold toward the bar, the movement, however, being in the reverse direction, so that the said eyepiece-frames 70 will overlap the objective frames j, as shown in Fig. 2. Thus the four lens-frames can be compactly folded together in a very short and narrow space and be retained in folded relation when turned into the case. After folding the said lenses, as described, and pressing them into the said case they are held therein by engagement with the catch 0. By disengaging the catch from said folded frames the spring g in the drum throws the sectional armthe'exerted power of the springs on their pivots, as described, and thus by simply operating the catch the four glasses automatically assume positions enabling the device to be used after the fashion of an ordinary operaglass, and when in operative relation the lenses in the frames may be focused to suit the eyes by means of the nut and screw 01 m.

I am aware that various changes in detail construction may be made without departing from the invention, and I do not Wish to limit myself by positive descriptive expressions hereinbefore employed excepting as the state of the art may require.

Having thus described the invention, what I claim as new is- 1. The combination of a collapsible operaglass frame pivotally mounted upon a rewhen collapsed, and provided with means for retaining said frame within, and positively releasing said frame from, said case, with means for automatically erecting the lenses of said frame in focal relation when released.

2. The combination with the case provided with a handle, of a pivoted sectional bar adapted to fold into said case and pivoted objective and eyepiece lenses adapted to fold toward said bar and with it enter the case, substantially as set forth.

4. The combination with a case provided with a pivot, of a sectional bar adapted to turn on said pivot, and objective and eyepiece lens frames pivoted respectively upon opposite ends of said bar and adapted to fold toward each other to lap one over the other and lie parallel with said bar, and with said bar be folded into the case.
