-1 Claim. 1

The present invention relates to a novel artiole of manufacture, and more particularly to a nose block for spectacle cases.

Heretofore nose blocls for optical cases have been made of wooden blocks shaped like an isosce es triangle with an opening bored therethrough for the usual stud, which serves to se cure the block in the optical case.

This prior shape of nose block has been found unsatisfactory particularly for Zyl frames, that is, a pair of spectacles with rims around the lenses, as the rims are pressedagainst ;the lower portions of the sides of the triangular blocks. Such pressure not only tends to twist and Warp the bridge which connects the lenses together, but causes breaking of the lenses and in particular at their connection to the arms of the bridge piece. The same is true Where frameless spectacles are used.

Accordingly one object of the present invention is to eliminate any contact of the lens rims or the lenses with a nose block, by providing straight sides from the base of the nose block, to thereby leave a gap between these sidesand the lens rims or the edges of the lenses depending upon the type of spectacle mounted thereon.

These prior wooden nose blocks are usually cut out from Wooden panels of a predetermined thickness which are first treated and painted or varnished. Considerable care and time is required for the proper selection of the Wood to be treated and out up into blocks or the blocks will split along the grain while they are being cut out. Also, every block out must have a stud hole bored through it, and unless the wood is cut on the proper bias of the wood grain the blocks will split during the stud hole boring step. Furthermore, after a wooden nose block has been finished it is not of durable nature, and will split if the blocks are not handled carefully and when made for shipment as articles of anufa if not packed prior to this final installation in an optical case, they will become damaged or split.

This disadvantage of splitting of wooden nose blocks is still present after they are installed in an optical case, and it has been found that they frequently split even without dropping or jarring the optical case in which they have been mounted due to their weakened condition from the stud hole boring step.

Accordingly another object of the present invention is to provide a novel metal nose block which is less expensive to manufacture than the prior wooden blocks, extremely durable and will not split during manufacture or during use.

A further object is to provide a novel metal nose block which can'be stamped, forged or molded from inexpensive sheet metal in one operation and requires no prior or subsequent painting or othertreatment such as is required in the manufacture of wooden nose blocks.

And still another object is to provide nose blocks formed with a countersunk stud opening, whereb the stud openings may be stamped and simultaneously formed with a hole and a countersunk well around the openingin one simple operation.

The above and other objects andnovel features of the invention will more fully appear from the following detailed description when the same is read in connection with the accompanying drawings. It is to be expressly understood, however, that the drawings are for purposes of illustration only and are not intended as a definition of the limits of the'invention. Reference should be had to the appended. claim to determine the limits of the presentinvention.

In the drawings wherein like reference characters refer to likeparts throughout-the-several views:

Figure 1 is a perspective view of a novel nose block mounted in a leather optical case.

Figure 2 is a rear view in perspective of the novel nose block.

Figure 3 is a longitudinal cross section view of the novel nose block showing a mounting and fastening stud and partial section of an optical case through which the stud projects, and

Figure 4 is a front elevation of my novel nose block showing it attached within an optical case, and showing a pair of spectacles mounted over the block.

Referring to the drawing, in detail, in the illustrated embodiment of the present invention, the device comprises a body it of a sheet of rigid material bendable under pressure or heat, such as a plastic or a metal. This material has been stamped, forged and punched in one operation by opposed cutting, forming and punching dies, not shown, into a five-sided body or pentagon member, specially shaped to protect the nose bridges of eyeglasses when the body I d is mounted in an optical case H by a stud H2. The stud l2 is of a conventional type and includes a head l3, a shank l4 and round rib l5 adapted to cooperate as a part of a snap fastener, not shown, in the optical case flap to.

The nose block comprises a front panel or plate H of polygonal shape, bounded on all sides by a continuous flange 18 extending rearwardly from each edge of the plate IT in difierent planes perpendicular to the plane of the plate IT.

For example, in one plane the flange extends rearwardly to provide a base portion 20, in another plane perpendicular to the base, the flange defines a pair of substantially parallel side portions 2| and 22, respectively. These side portions continue from the base portion 20 at each round corner 23 and 24 of the body.

In still two other planes, the flange extends onwardly from the side portions 2| and 22 into converging portions, 26 and 21 respectively.

The converging portions 26 and 2'1 terminate in a round nose or point 28. Thus there is provided a hollow body having a specially shaped top or front plate l7 bounded by walls or flange portions 20, 2|, 22, 26 and 21, all of which portions are part of a continuous flange 18 extending rearwardly from the plane of the plate l1.

Above the base 20 and between the two parallel Walls 2| and 22, the plate H is pushed in so as to define a countersunk portion or well 30. The center of the well 30 is punched out to provide an opening 3|, which receives the stud 52.

When the nose block 10 is applied to the inner wall of an optical case H, as best shown in Figure 3, the stud has its shank 14 extending beyond the edge of the flange and on through the wall of the case.

The stud l2 secures the nose block to the leather Wall of the case H as its head i3 seats at the bottom of the well or countersunk portion 30, and this head pulls the edges of the continuous flange 18 against the leather wall of the case when the end of the stud is upset against the outside wall of the case into the rounded portion l5, previously mentioned, which cooperates to fasten the closure flap of the case.

The function of the novel configuration of the nose block of the present invention is illustrated in Figure 4, which shows a pair of frameless spectacles 40 mounted on the same. For example, the bridge 4! with nose engaging pads 42 and 13 of the spectacles fits over the rounded point 28 engagement with the nose block flange portions 26 and 21 and the lenses 44 and 45 of the spectacles are spaced away from the flange portions 2! and 22 for the reasons hereinbefore e plained.

Without further description it is ught that the advantages of the present novel nose block over the prior art will now be apparent and there is thus provided a novel nose block adapted to provide greater security against lens breakage than heretofore. Also, there is provided a more economical durable, and superior article of manufacture than heretofore was possible for such articles.

What I claim is:

A spectacle case nose block comprising an elongated one-piece polygonal body having a front plate tapered at the top, said plate being bounded by flanges at right angles to each other around its lower half and bounded by upwardly converging flanges around its upper tapered top, and a countersunk opening in the lower half of said plate for a stud to project through to thereby secure the body within a spectacle case.
