1 Claim.

to the bars in the approximate center of the grille as a utilitarian as well as an ornamental feature.

Another object of the invention is to provide an arrangement as set forth whereby the device attached yto the grille will assume the desired position when the grille is expanded or contract-ed to conform to an opening, depending upon the manner or position in which it is origi nally applied to the grille.

With the foregoing objects as paramount, the Y invention has particular reference to its salient features of construction and arrangement of parts which will become manifest as the descrip'- tion proceeds, taken in connection with the accompanying drawing, wherein:

Figure 1 is a front elevational view of the invention, showing the grille expanded and the i attached device in dotted lines,

Figure 2 is a fragmentary View of the grille contracted, showing the attached device in solid lines and its manner of changing positions when the grille is contracted, and

Figure 3 is another fragmentary view of the grille, showing a mail boxas an attached device.

Continuing with a moreY detailed description of the drawing, it is first pointed out that the most popular type of grille is the intercrossed bar type in which the ends of the bars are curled, such as shown in applicants co-pending application, Serial Number 204,182, now Patent No. 2,210,371 issued August 6, 1940. This type of grille, however, has no provision for the application thereto of a name plate or other such device other than by perforating the bars to ren ceive screws or rivets for holding the attachment. It is obvious that to attach a device to such a grille would render the latter incapable of adjustment as to length and width, the rivets restraining reiative movement of the bars.

'I'he present invention provides for the attachment to the bars of the grille any desired form of device without hindering lateral or vertical adjustment of the grille by restricting or preventing relative pivotal movement of the intercrossed bars constituting the same.

Accordingly, l designates obliquely disposed bars arranged to intercross bars 2, each being pivoted to the other at a, in the form of a toggle. However, there is provided in the present case a pair of axially aligned intermediate bars 3, similar in all respects to the bars l and 2 with the exception that the bars 3 terminate at b near the center of the grille and on opposite sides of the central corresponding bar, at which point they are perforated as at c. At the outer ends of each bar there is provided aV scroll or curl 4.

At the top of the grille, a horizontal arrangement of bars 5 is provided, adjustable to conform to the effective width of the grille, each bar being provided with an end scroll 6 which is riveted to the sides of the opening in which the grille is installed.

The horizontal bars are secured to the grille by close fitting collars l, the latter also securing the decorative-member 8 to the grille. This arrangement affords a means to prevent Whipping of the upper scrolls of the grille and forms the .subject matter of the above identied c0- pending application.

Returning to the subject of the present invention, it will be observed that a name plate 9 is pivoted at the points c to the inner perforated ends b of the bars 3 and at d to the central bar I midway of its ends.

In Figure 3, a mail box l 0 is mounted in a manner similar to that just described.

It is apparent that before attachment of the plate 9 in the manner described, each bar section 3 may be swung independently of all other bars about the pivot a. Also, before attachment of plate S, bar section 3 may be subjected to a movement of translation which will cause the grille to assume rhomboidal shape. After plate 9 is attached, the pivots allow movement of bar sections 3 whichwill cause all members to move to still another outline, thus providing greater adjustability than heretofore possible.

It is apparent from the foregoing that a grille such as described may be sold to a purchaser who may select his own device for attachment to the grille, and when attached in the manner provided for, adjustment of the grille either horizontally or vertically is not interfered with in any manner as would be the case were it not for the provision of the relatively short bars 3, perforated as they are for the reception of rivets for retaining the device 9.

It is to be noted that the device 9 is first seassume the desired position when the grille is adjusted to a position in'xed relation to an opening.

Manifestly, the construction as shown and described is capable of some modification and such modification as may be construed to fall within the scope and meaning of the appended claim is also considered to be Witlin the spirit and intent of the invention.

What is claimed is:

A grille for screen doors and other openings comprising in combination, two sets of relatively spaced bars, the bars of one set intercrossing.r the bars of the companion set, each bar of one set being pivoted to the intercrossing bars of the cured to the grille .in 'such a position that it will companion set at each intersection; a` pair'of axially alined bars supplanting the` intermediate bar of one set, each having a singlepivotal connection intermediate its ends to apoint intermediate the ends of bars of the companion set and Whose inner and outer ends are displaceable rel-- ative to the remaining bars of their set and tothe bars of the' companion set, the inner ends of said pair of bars terminating on either side of" the corresponding bar of the companion set and; utilitarian means pivoted to the inner ends of said complementary bars and to a point midway between the ends of said corresponding barr whereby to be movable independently of the com-- panion bars of said grille.
