I LAMP SHADE Mary E. Morgenroth, Chicago, in. 4 Application November 13, 1244, :Serial No. 563,157 h 1 Claim. (01. 240-108) F i My invention relates to lamp shades; and more particularly to the manner of their application to their supporting frames.

Lamp shades are usually made of silk, cloth or other fabric; and some are made of paper. In either case the shade is mounted on a skeleton type .of frame-to lend it support and the desired form. When made of textile material, the shade is usually stretched over a wire frame, turned in with hems over the top and bottom bands of the frame, and the hems sewed secure. In the case of the paper shades, these are pressed on their frames and made secure by an adhesive. In either case the job is a permanent one, whether done by hand or machine; and the assembly of the shade and frame must be entirely discarded in case the shade becomes badly soiled, worn or torn. Sincethe metal frame in the case of a textile lamp shade is of a nature to last indefinite- 1y, it is a wasteful practice to discard it along with the shade, and one object of the present invention is to devise the combination of a shade and frame which enables the shade alone to be renewed and replaced in theevent it becomes soiled, otherwise unfit or unsightly.

A further object is to provide a shade which may be sold as a unit in any number of designs or patterns and in sizes suitable for application to or wrapping around standard lamp shade frames improved in accordance with the present invention.

Another object is to design the combination of a shade and frame therefor with means cooperative to easily apply and securely fasten the shade to the frame. I

A still further object is to construct a lamp shade frame with means to have a shade secured to the same by snap fasteners, string loops' or a threaded cord.

With the above objects in view and any others which may suggest themselves from the description to follow, a better understanding of the invention may be had by reference to the accompanying drawing, in which Fig. 1 is a perspective view of a conventional lamp shade frame improved with the basic form of the invention at the top;

Fig. 2 is a similar fragmental view, showing the basic improvement both at the top and bottom;

Fig. 3 is a developed view, partly broken away, of a shade applicable to the frames illustrated in Figs. 1 and 2;

Fig. 4 is a sectional detail showing the use of the band a snap fastener in assembling the shade with the frame; and

Fig. 5 shows a modified shade employing the principle of the invention.

In accordance with the foregoing, specific reference to the drawing indicates the top band of. a conventional lamp shade frame at ID, the bottom wire ring at H, and the inclined wire stays at a I 2.

A shade for a frame of the above character may be made in the customary finished form, which is frusto-conical; or it may be supplied in the fiat or developed form. This is the original form of d the shade in either case and is illustrated at l3. The shade is applicable to the frame in either the original or finished form after means for securing it to the frame have been provided. In respect to the frame such means involve the basic formation of the top band ll] with a longitudinal series of round perforations l4. When the finished shade has been lowered on the frame--or one in the original form wrapped around the samethe perforations l4 permit the attachment of the top portion of the shade to II) by string loops from the shade at each occurrance or by a long cord threaded from the shade through the band by way of the perforations. 7 As these securing methods are obvious, their illustration is not believed necessary.

While the shade securing means jsut mentioned are feasible and may prove eflicient, they involve more or less labor and time, and my purpose is to utilize the perforations in the band In to better advantage. Thus, Figs. 2 and 4 show that one component l5 of a standard snap fastener has been'fitted in each perforation l4; and Fig. 3 shows that the other component l6 has been applied in a series along the top of the shade I3. With both sets of components correspondingly spaced, it is apparent that the shade-whether lowered upon or wrapped around the framemay be quickly secured to the same by the coupling of the related snap fasteners, so that the shade forms a, covering for the frame.

In case it is desirable to secure the shade more firmly or tautly in respect to the frame, the above fastening may be duplicated at the bottom by making the frame with a bottom band I! instead of a wire ring, as shown in Fig. 2. Dotted-line circles in Fig. 3 indicate the application of snap the shade easily removable for cleaning or replaceable Whenever a change is necessary or advisable. Further, the assembly is no longer a custom or factory product, as the shade can be purchased by the'owner of the lamp in any design or pattern and in a size made to fit the particular frame. Also, the shade need not necessarily be stocked in the finished form, which makes end creases when it is collapsed, but may be compactly carried or stored and sold in the original or fiat form, forthe customer to wrap around the frame and fasten the shade to the same as previously described. Or, the shade may be made in petal-like sections l9, as shown in Fig. 5, applicable by individual fasteners 20 in overlapping sequence. In conclusion, the invention not only conserves the lamp shade frameas-a fix ture, but facilitates the removal and. replacement of lamp shades by the owner as often as desired, in a most simple manner, and withrthe'possibility of a wide choice of designs and patterns when the shade is replaced.

While I have described the invention along basic and modified lines, various other minor changes or refinements may be made therein without departing from its principle, and I desire to consider such changes and refinements as coming within the scope and spirit of the appended claim.

I claim: I l r A lamp shadecomprising a frame of skeleton form, said frame having at least one band formed with one of the components of a snap fastener in a longitudinal series, and a shade for said frame having at least one series of the other component of said snapfastener positioned to engage the frame series when the shade is mounted on the frame.
