EDWIN B. NATHAN, or MOUNT VERNON, AND FRANK NATHAN, on NEW YORK, N. Y.

CURTAIN WINDOW.

Application filed October 12, 1923. Serial No. 668,088.

To all whom it may cancer rt:

Be it known that we, EDWIN B. NATHAN and FRANK NATHAN, both citizens of the United States, residing, respectively, in the city of Mount Vernon, county of Westchester, and the city of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Curtain Windows, of which the is following is a specification.

This invention relates to improvements in curtain windows and methods of making the same. More particularly the invention is directed to window lights for the tops or curtains of automobiles, carriages and the like, an object of the invention being to provide a window of the character described having a securing frame of improved construction which results in a material saving of metal stock.

Another object is to provide a window of the character described in which the securing prongs of the frame member are integral with the inner edge thereof and bent so as to lie fiat for a portion of their length against the inner face of the frame member,

thereby strengthening said frame member and increasing its rigidity.

A further object is to provide a window frame of the character described the parts of which can be stamped from sheet metal or other suitable material with the securing prongs of the clamping member formed at the inner edge thereof, so as to avoid the wasting stock incidental to constructions heretofore made in which the prongs were formed at the outer edge of the clamping member. I

A still further object is to provide a window frame of the character described which may be readily assembled in connection with the transparent member so as to provide a neat, practical and eflicient construction at a comparatively low cost.

Other objects of this invention will in part be obvious and in part hereinafter pointed out.

The invention accordingly consists in the features of construction, combinations of elements and arrangements of parts which will be exemplified in the construction hereinafter described and of which the scope of application will be indicated in the following claim.

n the accompanying drawing, in which 7 is shown one of the various possible'illustrative embodiments of this invention,

Fig. 1 is a View in elevation, partly broken away, illustrating our improved window;

Fig. 2 is an enlarged cross-sectional view taken on line 2+2 of Fig. 1;

Fig. 3 is a plan view of the clamping member of the frame showing some of the prongs bent into operative position; and

Fig. 4 is a plan view of the other frame member. v

Referring in detail to the drawing, 1 represents a fragment of curtainin which our improved window 2 is secured. The curtain 1 is made preferably of suitable flexible material, and the window 2 may be of glass or other transparent or translucent material. The window 2 is secured in an opening 3 in the curtain 1 by my improved frame comprising a clamping member 4 and a frame member 5.

These members 4 and 5 are preferably stamped from sheet metal and may be of any desired shape. In the form shown in the drawing, the window illustrated is of general oblong or rectangular shape and hence the members 4 and 5 are of like shape and have preferably rounded or curved corners for neatness. Figures 4 and 5 show the separate members 4 and 5 as they are stamped from the sheet. The frame member 5 is slightly smaller than the clamping member 4, but both members have openings of the same size and shape for the window 2. The clamping member 4 is formed at its inner edges with integral prongs 6 which preferably taper from their inner to their free ends and terminate in sharp points which can be easily forced through the material of the curtain 1.

After the clamping member 4 is stamped, its rongs 6 are bent outwardl and flat against the inner face thereof. he prongs 6 are longer than the width of the frame bars and their extremities are bent at right angles forming sharp curtain puncturmg devices, as shown at 7, which are bent over the outer face of the frame member 5 to clamp the parts together as will more fully hereinafter appear.

To give added strength, and also for purposes of ornamentation, the bars of frame member 4, as well as the main portions of the prongs 6 are bent or curved transversely and convexly as shown most clearly in Fig. 2.

The window is preferably made in the following manner: An opening 3 of proper size is cut in the curtain 1 and a window or light provided which is larger than the opening is provided to cover the same. The window 2 is positioned against the curtain l with the frame member 5 against the same. The frame member 4 is located against the outer face of the curtain and the sharp ends 7 of prongs 6 forced through the curtain and bent flat against the frame member 5 tlier eby securely clamping the window in p ace.

It will thus be seen that the process or method by which the window curtain frame is made is exceedingly simple and affords an economical, cheap and durable construction.

It will thus be seen that there is provided a device in which the several objects of this invention are achieved and which is well adapted to meet the conditions of practical use.

As various possible embodiments might be made of the above invention and as various changes might be made in the embodiment above set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawings is to be interpreted as illustrative and not in a limiting sense.

Having thus described our invention, we claim as new and desire to secure" by Letters Patent In combination, a Window and front and rear securing frames adapted to retain the Window in a closure opening, prongs integral with the inner edges of the front frame and disposed to lie thereagainst, said front frame and prongs being; bent convexly outward, the extremities of said prongs being offset at substantially right angles with respect to the frame at the outer edges and adapted to ,serve as a puncturing means to be forced through the material forming the closure, said end prongs engaging over the outer edge of the rear frame for retaining the window against the outer and inner rim edgesof the convexly shaped front frame.

In testimony whereof we affix our signatures.

EDWIN: B;- NATHAN. FRANK NATHAN.
