FREDERICK A. STEVENS, OF PROVIDENCE, RHODE ISLAND.

LENS-CASE Specification of Letters Patent.

Patented July 16, 1907.

Application and March 15,1907. Saris-1N0. 362.489.

To all whom it may crmcem:

lie it known that I, FREDERICK A. Srsvsns, a citizen of the United States, residing at Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Lens-Cases,'of which the following is a specification, reference being had therein to the accompanying draw- My invention relates to receptacles for lenses, particularly to, uncut lenses, which heretofore it has been the custom to inclose for transportation in 9. rolled paper bundle, whereby the particular lenses sought were and claimed;

In the drawings which form a part of these specifications, Figure 1 is a perspective view of the novel case closed. Fig. 2, plan view of the case interior in open position. Fig. 3, a section of the same on lines: a: of Fig. 2. Fig. 4, a section of the same on line 3 y of Fig. 2, and Fig- 5, a vertical section of a pocket enlarged, showing the pocket lining.

Like reference characters indicate like parts throughout the views.

A strip, A, of paper, skin, or other flexible material forms the body or outer covering of my case, of which one end, a, forms a lapel. Upon the interior face of the oblong strip, A, are a series of pockets, B, arranged in couplets transversely of the strip, the couplets extending in succession from the lower end of the strip up to the lapel portion thereof; and each couplet being interspaced from the next adjacent couplet a greater distance than between the next lower couplet, as shown at b, b, b, b",,a nd b, in Fig. 2. Each pocket is open at the top, and has its upper edge, b, upwardly curved,

for the purpose of facilitating the insertion of the lenses.

The lapel is provided with an opening, 0, to permit passage therethroughof fastening prongs, D, fixed to the outer face of the covering, A. The pockets are preferably lined with strips of cloth or other material, F, to prevent scratching of the lens surfaces.

G represents concave convex uncut lenses, whose margins extend slightly beyond the tops of the pockets, B. The lenses are arranged thus: One couplet has its convex surface against the inner wall of the pocket, while the next adjacent couplet has its convex surface against the outer wall of the pocket, and this alternate arrangement continues throughout the case; Thus it will be seen that in folding the case from bottom to top the lenses rest in compact layers with the convex sides of one lens couplet resting in the concave'sides of the adjacent lens couplet. Furthermore, the interspaced portions, b, b, etc., which increase in width from bottom to top of the strip, A, make suitable provision for the constantly increasing thickness of the case as it is being rolled and render it feasible for the convex sides of one lens couplet to snugly rest in the' concave sides of the adjacent lens couplet so as to contribute to the compactness of the case as a whole, and, at the same time, assure the lenses of one couplet being supported or reinforced by the lenses of the adjacent or cooperating couplet. that the pockets serve in the folded case to separate the lenses in one couplet from the lenses in an adjacent or cooperating couplet and in that way preclude the lenses of cooperating couplets scratching or otherwise marring each other.

What I claim is,

1. in a lens-case, the combination with s. flexible strip, of-a series of. pockets, of flexible or soft material, located upon ,the inner face of the'strip and separated by interspaccd portions of strip which increase in width toward one end of the strip. a

2. ln s. lens-case, the combination with n flexible strip, or a series of transverse couplets oi! pockets, of flexible or soft material, located upon the inner face of the strip; the said couplets being separated by interspsced portions of strip which increase in width toward one end of the strip. in testimony whereof I have sfllxed my signature in presence of two witnesses.
