Original application filed October 1.8, 19 e i N 7 ,3; D i a d hi l ia fi ed Marga This case is a division of my .coepending application Serial No. 744,313, filed Octoba 1 1. 2 a

This invention relates toa novel and 1mpnoved arm particularly one from which arms may be .cut for use vvithdisplay raq s. It ,is the object .of the invention to provide an arm which shall-be strong enough to carry the heavy loads imposed thereon .and at the same time shall be light in weight, easily made andone which willretainit shape.

vIn the accompanying drawings in which I have shown aseleetedembodiment of this invention: r

Fig. 1 is an elevatien .of a dlsplay rack having an arm construe-ted of my novel and iniprouedarm. v d 7 Fig. 2 is an enlarged transverse section ,through the arm ,ofFig. 1.- p v Fig. 3 is anenlarged elevation of the same arm. p i

Fig, dis a section on the line of ,Eig. 2,. drawn .on an enlarged scale,

In Fig. 1 ,thearm 1 is pivoted iat2 to .a hinge ;bar ,3 secured to a Wall plate gwhlch in turn is attached to the avalle, or ;other suitable support. The outer end of vthe arm is provid t jro l r 6 adapted to keep the .arm 1 spaced from other, arms ,vv-h ch may be mounted upon .the ihinge plate, as s Well known in the art. ,Eaeh arm-ispreferably provided with a brace 7 to support it in 'ithe correct posit on, Eas'set forth in my aforesaid co-pending application.

Referring now particularly to Figs. 2 and 3, it will be seen that the arm is made from a single sheet of material, such as sheet metal and comprises a vertical stem 8 and a head 9, these forming a T-beam. The stem 8 1s m the form of a U having substantially vertical parallel sides 10, these sides being formed by bending the material as at 11. It Wlll be noted that one of the sides 10 is shorter than the other and as shown in Fig. 2 this side, which is the left one, has its upper end bent at 12 at substantially right angles to the vertical portion of the side to form a portion 13 of the horizontally disposed head 9. p

The other side 10 is bent at 14 to form a portion extending in substantially the same plane as the portion 13, and is then bent on itself at 15, depressed at 16 between the tops of the sides 10 and it is then carried over the Serial m. 32,611.

From the above it Will be evident that I have provided an arm from which arms may be cut for use With a display rack, or Which may be used for any other structural purpose for Which it maybe adapted, and which .is extremely light in Weight, at the same time possessing the requisite strength. F urthermore, my novel and improved arm is very cheaply and very easily made because, it is possible to manufacture iton a drawbench instead of employing a press. Furthermore, it may be easily manufactured in long pieces, from Which any desired length may be cut. The vertical stem With its tWo parallel sides furnishes a ready means for making connections of a piece of arm to other elements. All that is necessary is to insert a portion of the other element be tween the two sides which may then be pressed into engagement therewith, as 6X' emphhed ll'ifily CO-PGl'lCllHg application.

I am aware that changes in' the form, construction and arrangement of parts may be made without departing from the spirit and without sacrificing the advantages of the 10 invention and I reserve the right to make all such changes as fairly fall within the scope of the following claims.

I claim:

1. A display rack arm in the form of a T and formed of one piece of sheet material,

the stem of said T being in the form of a U, the sides of said U being bent outwardly to form the head of said T, and one of said sides being longer than the other and bent upon itself and'overlying the said other side terial beingin contacting relation with each other.

i 2. A display rack arm comprising a single sheet of material bent into the form of a T,

the stem of said T'being in the form of a :40 U, one of the sides of said U being longer than the other and each side being bent outwardly at right angles from the U to form the head of theT, the longer of said sides being folded back upon itself, depressed be- 35 tween the sides of said U, and overlying and folded under the outwardly bent portion of said shorterside. I

3. A display rack arm comprisinga single sheet of material bent into the form'of a T, 40, the stem of said T being in the form of a U, one of the sides of said U being longer than the other and each side being bent outwardly at'right angles from the. U to form the head of the T, the longer of said sides being folded back upon itself, depressed between the sides of said U, andoverlying and folded under the outwardly bent portion of' and formed of one piece of sheet-material,

the stem of said T being in the form of a U, the sidesof said U being bent outwardly to form the head of said T, and one of said sides being longer than the other and bent upon itself and overlying the said other side, said sides being knurled adjacent their edges to prevent relative longitudinal movement therebetween.

5. A display rack arm in the form of a T and formed of one piece of sheet material, the stem of said T beingin the form of a U, the sides of said U being bent outwardly to form the head of said T, and one of said sides being longer than the other and bent upon itself and overlying'the said'otherside and folded thereunder, said sides being knurledadjacent their edges to prevent relati've longitudinal movement therebetween.

6. A'display rack arm comprising a single sheet of material bent into the form' of a T,

the stem of said T being in the form of a U, one of the sides of said U being longer than the other and each side being bent outwardly at right angles from the U to form the head of the T, the longer of said sides being folded back upon itself, depressed between the sides of said U, and" overlying a'nd folded I under the outwardly bent portion of said shorter side, said sides being knurled adjacent their edges to pre'vent relative longitudinal movement therebetween.

' 7, An arm for a display rack, comprising i an elongated unitary member T-shaped in cross section, the stem of thesT being U shaped and the head of said T formed of contacting lateral portions'of said member, and the said head having a depression ex tending into the sa-id'stem.
