March 4,' 1941. M. A. BOWERMAN' WINDOW SHADE ATTACHMENT Filed Aug. 2, 1959 nwal fNvENToR E" WAM?,

ATTORNEY` Patented Mar. 4, 1941 UNITED STATES PATENT OFFICE 2 Claims.

hem in the latter, which may be employed in connection with any type of window shade, which may be secured or removed without damage to the window shade, even by unskilled persons, and whereby the reversal of the window shade may be conveniently eected,

Another object of my invention is to provide a device of the above described character which ymay be readily attached to window shades already in use without modifying the latter and to window shades in which the hem portion has been severed or partially severed therefrom.

A further object of my invention is to provide 20, a device of the above described character which is simple in construction, durable in use, efficient in operation and economical in manufacture.

Other objects and advantages will be apparent from the following description, appended claims and annexed drawing.

Referring to the drawing wherein like reference characters designate like parts throughout the several views:

Figure l is an elevation of a window shade illustrating my invention as applied thereto.

Figure 2 is a detail sectional View, on an enlarged scale, taken on the line 2--2 of Figure 1 and illustrating my invention in attached condition to a shade. v

Figure 3 is a View similar to Figure 2 butillustrating my invention in condition for removal from or attachment to a shade.

In practicing my invention, as illustrated in the drawing, I provide a window shade 5, the

I o upper end (not shown) being attached to a shade roller 6. The lower end section 'I of the shade has attached thereto my improved form of window shade attachment 8, the latter comprising an elongated relatively thin resilient body inflected between its side edges to dene adjacently disposed side walls 9 and I0. The side wall 9 is formed with a longitudinally extending upper edge section II bent upon itself as at I2 and terminating ina beaded portion I3 disposed away from its wall 9, The side wall ID is formed with a longitudinally extending intermediate section I4 having a portion I5 bent upon itself and termnating in a loop I6 fashioned with a lengthu wise extending edge section I'I disposed in proximity to the section II for clamping therebetween a portion of the lower end section of the shade 5. The loop I 6 denes a lengthwise extending channel I8 in which the portion I3 extends a suicient distance to coact with the wall of the l channel to cohibitv movement of the walls 9 and I0 in a direction away from each other. When the portion I3 is thus disposed within the channel I8 the intermediate section I4 coacts with the wall 9 to clamp an adjacent portion of the shade l0 5 therebetween. The lower side edge of the body has swiveled thereto an eye I9 to which is attached a shade raising and lowering cord 20 whereby said shade may be operated.

From the foregoing it will be apparent that l5 when the walls 9 and I0 are urged in a direction away from each other, the lower edge section of the shade 5 may be inserted therebetween as clearly illustrated in Figure 3 of the drawing. When the lower edge section of the shade is thus .l0 inserted between the walls 9 and I 0, said walls are moved ina direction towards each other causing the beaded portion I3 to snap into the channel I8 and elTect clamping of adjacent portions of the shade between the sections I I and u Il and the section I4 and wall 9 subjacent the section II respectively, thereby providing an attachment by which the lower non-selvedge edge of the shade is protected from raveling and for operating the shade.

It is obvious that the invention is not coniined to the herein described use therefor as it may be utilized for any purpose to which it is adaptable.

It is therefore to be understood that the invention isnot limited to the specific construction 85 as illustrated and described, as the same is only illustrative of the principles of operation, which are capable of extended application in advance forms, and that the invention comprehends all construction within the Ascope of the appended o claims.

What I claim is:

1. In a device of the character described, comprising an elongated relatively thin resilient body portion having its upper edge bent inwardly Aand 5 downwardly and turned upwardly to form a beaded portion, the lower edge of the body portion bent upwardly to a point opposite to the beaded portion of the downwardly turned portion, the upper edge thereof turned downwardly and upwardly and ared outwardly, whereby when a piece of fabric is placed between the lower edge of the downwardly bent portion and the upper edge of the upwardly bent portion the fab- M ric is clamped at three distinct points when the loop portions are snapped together.

2. In a device of the character described comprising an elongated relatively thin body portion having its upper edge bent inwardly and downwardly, the lower edge of the body portion bent upwardly to a point opposite the lower edge of the downwardly turned, portion, the upper edge thereof turned downwardly and upwardly and flared outwardly, whereby when a. piece of fabric is placed between the lower edge of the downwardly bent portion and the upper edge of the upwardly bent portion, the fabric is clamped at three distinct points when the loo-p portions are snapped together.
