RELEASING MECHANISM.

To all 'wkomit mag/wncern;

Be it known that I, SAMUEL SEOKENDORI;

a citizen. of the United States, residing at New. York, in the county and State of New York, have invented certain new and useful Improvements in Releasing Mechanism, of which the following. is a full, clear, and exactdescription.

The invention which constitutes the sub-. 1

ject: matter of thisapplication relates-to a lorgnette or eye-glass, theconstruction, objects, operation;;and advantages of which will appear from the detailed description '1" Fig. 2' isv arear view illustrating the device. in completely closed position suspended from its cord 01 chain. r

Fig. 3 is a longitudinal section taken pentrally through Fig. 2 but looking in a direc- .tion at right angles to the view in Fig. 2.

Fig. 4 is an enlarged 'detailillustrating the novel-means for maintaining or holding the lorgnette in folded position. 7 V Fig. 5 is a detailview illustrating the re.

- silient connection-between the two bridge portions connecting the glass settings or frames.

Referring. to the drawings in detail the reference numeral-'10 designates a sheath or mounting preferably of rectangular construction, provided with an outer fiangeor gallery 11 and a stem 'orneck portion 12,

the end of'which is connectedto a cord or f chain 13 from which the lorgnette is nor-.

mally suspended. The mounting is adapted to receive the frames 14 and 15 .of the glasses.

These frames are. providedwith bridge por-.v

tions 16 and 17,respectively, pivoted to each other at 18. The frame 14 is pivotedat 19 to the mounting 10.

In folding the lorgnette the frame 15, as viewed from Fig. 1, is rotated in a folding direction about itspivotal point 18 as a center until it comes into contact with and lies flat upon frame14. The two frames or set tings are now moved or folded bodily in a direction about the pivot 19 as a center until they lie flat upon the bottom of the mounting 10, in which condition the frames 14 Specification 'of Letters Patent.

not only enables the setting or frame 15 to v Patented Mar. 11, 1919. Application filed May 10, 1917. Serial No. 167,672. r

. and 1 5 willbe within the borders ofthef be positionedbetween the setting 14 and the sheath 11, but also enables the successive folding movements to take place in planes.

extending in the same: general directions.

The chain l3'is connected to the stem or neck 12 through the ring 21, spring pressed plunger 22 and casing, 23, in which said plunger is located, said casing being rigidly mounted in saidnecki 12; The plunger 22 is provided with a shouldered portion, 'or piston'24 adjacent to lower end which snugly fits the cylindrical casing 23 and in which it has a limited reciprocating movement. To the shouldered portion 24 ispreferably attached a plurality of fins 25 adapted to slide in slots 26 in the casing 23. These fins and slots not only serve to limit the upward movement of the plunger 22, but also pre:

vent any rotary movement being imparted thereto. The plunger head 27, to which the ring 21 is attached, limits the downward movement of the plunger 22. The plunger also carries-a 'member 28 which in thefolding operation snaps into a notch 29 contamed in the end of the bridge portion 16,

,thelatter being rounded .or cam-edged in order to cam the plunger 22 outwardly against the tension of a spring 30, located gbetwee'nthe upper end of thecasing 23 and the shoulder 24.

So. long as the me1nber28 is in effective engagement with the notch 29 the lorgnette is securely heldinfolded position. If now it is desired to use the lorgnette a pull is exertedupon the chain 13 which retrieves the plunger 22, disengaging the member 28 from the notch .29 when 'the frames will spring out to their correct optical positions about their respective pivots as previously described. The frame 15, in folded position, locates itself between the frame 14 and the bottom of the sheath 10. When the member .28 is therefore disengaged from notch 29 the spring 31 surrounding the pivot pin 32 1 is strong enough to initiate the movement of the frames 14' and 15 to open position. From'the foregoing it will be seen that in the operation of folding the lorgnette or other spectacle the bridge portion is auto matically engaged by the spring-pressed plunger which looks the same in folded position and that when it is desired to use the lorgnette it is only necessary to exert a slight pull upon the chain 13. This chain is inva-' riably anchored and to use the lorgnette it is only necessary to grasp the sheath 1 and exert a slight pull thereon which disengages themember 28 from the notch 29 and the parts then open automatically under the tension of the spring 31. For all practicalpur- It will of course be understood that the i V bridgeportions 16 and 17 are provided with" able upon each other and provided with a poses'therefore the device may be manipu l'atedto open position by one hand. 1

cooperating shoulders which limitthe opening movement of the same, such'as that employed in connection with an ordinary hinge; it will also be understood that the frames 14 and 15, bridge portions 16 and 17 mounting 10 and shank 12'may be made of any desired material, and it will bef-ur-f ther understood that many changes may be made'inp'oint of detail and other embodilnents resorted to without necessarily deviating from the true spirit andscope of my 7 plunger for automatically interlocking said sheath and settings in folded relation.
