' Application filed May as, 1917. Serial No. 171,693.

- To all whom it may concern:

Be it known that I, Gnoncn H. LorLANn, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Im-.

roved Mounting for Lenses, of which the ollowing is a full, clear, and exact .description.

Among the principal objects which the present invention has in view are: to avoid breakage of lenses whenmounting the same in a handle; to reduce the cost of the mount-' ing; and to simplify the operation of providing lenses with service handles.

Figures.

Figure 1 is a side view of a lens and mounting therefor constructed and arranged in accordance with the present invention, part of the figure being cut away to show in section the interior construction;

Fig. 2 is a detail view in perspective showing a mounting band constructed and arranged in accordance with the present invention, said band being shown 1n its opened position;

Fig. 3 is a similar view showin a holding frame in closed position with a binding ring therefor constructed and arranged in accordance with the present invention;

Fig. 4 is a detail view on an enlarged scale showingend fragments of the holding frame and in the form assumed thereby prior to assembling the same;

- Fi 5 is-a detail view showing in perspective the binding ring employed for holding the ends of the framing; band together.

Description. As seen in the drawings, the lens 10 is I framed by a band 11.

Lenses of the character shown are sometimes irregular'in shape and dimension. For this reason it is expedient'to provide some means of connecting the ends of the. i

band which is adaptive'to these conditions.

To this end, the present invention employs mg reduced ends 12. The ends 12 are integral" with the band 11, and being centrally located in said-band, the groove 13 formed therein is also formed in said ends 12.

in forming the band 11, a continuous metal strip of proper width has routed therein the groove 13. Subsequently the strip is cut into separate pieces of dented the said. ends 12 when the outer extremities of the said ends are engaged. The combined efi'ect of the ends 12 is to form a-tapered extension from the ring-like band 11, said tapered extension operating in conjunction with the coil spring retaimng ferrule 16 to 11, which otherwise might operate to injure.

the lens 10. I

After the ferrule 16 has been disposed as shown in Figs. 1 and 3 of the drawings, the

hold the ends of the band together to .form

tube 17 is adjusted to infold the said ends 12 and ferrule 16. In practice, the tube 17 looselyv fits the ferrule 16. Solder or plastic setting-cement is then poured into the tube 17 to embed the ferrule 16 and ends 12, en-.

tering the inters'paces of the coil forming the ferrule and also entering the gap 15 between the ends 12. The surface adhesion of the solder to the tube 17 is suflicient to -maintain the said tube permanently engaged with the said ends and binding'ferrule therefor.

When the solder 18 above referred to congeals, the-handle'l and finishing feri'11le20 are adjusted to the tube 17, being adhered thereto by any suitable means.

1. A mounting as characterized com rising a centrally grooved framing band avintegral reduced ends extending from the joined ends of said band a proxnnately perpendicularto the connecte portions of said band; and means for holding said ends in juxtaposed relation and for exertmg a closure strain upon said band, said means. embodying a cylindrical member, a tube infolg'in'g said member, and a. filling forsald Q tu l 2. A mounting a characterized com rising a centrally grooved framing band aving integral reduced ends extending from the joined ends ofsaid band approximately perpendicular to the connected portions of said band; and means for holding said ends in juxtaposed relation and for exerting a closure strain upon said band, said means embodying a corrugated ferrule adapted for extension over said ends to draw the terminals of. said band toward each other, a tube for infolding said ferrule, and a suitable cement filling said tube in surrounding relation to said ferrule.

3. A mounting as characterized comprising a pliable metal band having reduced ends integrally formed with and extended from the terminals of Said band, said ends being partiallysevered from said band to form an angle therewith removed from the terminal extremities of said band; and a resilient cylindrical member fitting said ends for exerting a pulling strain thereon fordrawing the terminals of said band in juxtaposition.

4:. A mounting as characterized comprising a pliable metal band having reduced ends integrally formed with and extended from the terminals of aid band, said ends being partially severed from said band to form an angle therewith removed from the terminal extremities of said band; and a spring coil ferrule adapted for extension naeaoae over said ends for drawing the terminals of said band in juxtaposed relation.

5. A mounting as characterized comprising a pliable metal band having reduced ends integrally formed with and extended from the terminals of said band, said ends being partially evered from said band to form an angle therewith removed from the terminal extremities of said band; a sprin coil ferrule adapted for extension over sai ends for drawing the terminal of said band in juxtaposed relation; and means for permanently uniting said ends and said ferrule, said means embodying a suitable cement intimately surrounding and infolding said ends and said ferrule.

6. A mounting as characterized comprising a pliable metal band having reduced ends integrally formed with and extended from the terminals of said band, said ends being partially severed from said band to form an angle therewith removed from the terminal extremities of said band; a spring coil ferrule adapted for extension over said ends for drawing the terminals of said band in juxtaposed relation; and means for permanently uniting said ends and said ferrule, said means embodying a suitable cement intimately surrounding and infolding said ends and said ferrule; and a tube surrounding said ends, ferrule, and'cement uniting the same.
