Dec. 18, 1956 P. FORMENTI PROFILE ELEMENT FOR HARNESS FRAMES Filed Jun 27, 1951 INVEN TOR. P001 0 FOB/75W? United States Patent O PROFILE ELEMENT FOR HARNESS FRAMES Paolo Formenti, Carate Brianza (Milan), Italy Application June 27, 1951, Serial No. 233,784 Claims priority, application Italy June 23, 11950 4 Claims. (Cl. 13991) The present invention relates to a profiled metal element manufactured from a single sheet metal piece for use in connection with heddle frames and the like.

It is one of the objects of the invention to provide means resulting in a reinforced profiled element having folded flange means which increase the resistance to buckling, While permitting the use of a structure of extremely light weight. Another object of the invention is to provide means conducive to a profiled element of great strength with great resistance to both static and dynamic loads, which is made from one piece of sheet etal.

A further object of the invention resides in means affording an extremely economical profiled element which is easy to manufacure, which is readily cut into a plurality of elements of any desirable size and which has great rigidity.

These and other objects and features will become apparent from the following detailed description, reference being had to the drawing, in which preferred embodiments of the invention are illustrated.

Fig. 1 shows in perspective an element. embodying the invention.

Fig. 2 is a modified form of the invention schematically shown and somewhat in perspective.

The profiled element of Fig. l is obtained from a single piece of pressed, rolled, drawn sheet metal or the like, having its middle body A corrugated in order to obtain the necessary strength and rigidity. Longitudinal sides or end pieces B of the sheet are so bent at right angles to body A and upon themselves as to create two crosswise extending, parallel planes constituting longitudinal-guides for the sliding hooks supporting the heddle carrying blades '(not shown). The outer or end pieces 2 of the element are united to center body A on which they rest, by welding, for instance by electric welding or other suitable fastening means.

The profiled element illustrated in Fig. 2 has a middle or intermediary box shaped zone C in order to obtain the necessary rigidity of said element.

The box shaped portion is connected by means of end parts D to cross strip-like parts E to thereby form the Thus according to the invention a profiled element for use in heddle frames is provided which is formed from a single folded sheet metal, comprising'an intermediate body, and opposite T-shaped end pieces, saidint'erm'ediate body being provided with at least one portion offset with respect to the longitudinal center line passing through webs of said T-shaped end pieces, said T-shaped end pieces including each two web-forming strips substantially parallel to each other and substantially coinciding with said center line, furthermore two flange-forming strips extending from said web-forming strips in opposed direction to each other and substantially perpendicular to said longitudinal center line, at least one of said T -shaped end pieces being provided with a crossstrip interconnecting said two flange-forming strips adjacent the outermost ends, said flange-forming strips of said T-shaped end pieces extending in planes substantially parallel to each other and perpendicular to the plane passing through said center line.

It is preferred that the other of the T-shaped end pieces is also provided with a cross-strip interconnecting its flange-forming strips, one of said web-forming strips of said one T-shaped end piece being positioned in a plane different from that of the respective web-forming strip of the other T-shaped end piece, said respective one webforming strips of said T-shaped end pieces being oriented in opposite directions.

Said one web-forming strip of said one T-shaped end piece extends above the plane passing through the longitudinal center line, the one web-forming strip of the other T-shaped end piece being positioned below said plane.

The aforesaid intermediate body is preferably composed of two oifset portions each spaced a predetermined distance from said longitudinal center line and substantially level with said outermost ends of said flange-forming strips of said T-shaped end pieces;

Having thus described the invention, what is claimed as new and desired to be secured by Letters Patent, is:

1. A profiled element for use in heddle frames comprising a single folded metal sheet provided with an intermediate body, and with opposite T-shaped end pieces said intermediatebody being provided with at least one portion ofiset with respect to the longitudinal center line passing through the webs of said r shaped. end pieces, said T-shaped end pieces including each two web-forming strip parts substantially parallel to each other and posed direction to each other and substantially perpendicular to said longitudinal center line, at least one of said T-shaped end pieces being provided with a flatcrossstrip part interconnecting said two fiangerforming strip parts adjacent the outermost ends thereof, said flange forming strip parts of said T shaped end pieces being in height substantially coextensive with said offset portion and extending in planes substantially parallel to each other.

2. An element according to claim 1, wherein the other of said T shaped end pieces is also provided with a flat cross-strip interconnecting its flange-forming strip parts, one of said web-forming strip parts of said one T-shaped end piece being positioned in a plane different from that of the respective Web-forming strip part of the other T-' shaped end piece, said respective one Web-forming strip parts of said T-shapedendpieces being oriented in opposite directions. V

3. An element according to claim 2, wherein said one 7 Web-forming strip part of said one T-shaped end piece extends above the plane passing through the longitudinal center line, the one web-forming strip part of the other T-shaped end piece being positioned below said plane.

4. An element according to claim l, wherein said intermediate body is composed of two offset parallel por- I tions each'spaced a predetermined distancefrorn said Ion-f gitudinal center line and substantially level with said outermost ends of said flange-forming strip parts of said V o o 15 T-shaped end pieces. 7
