QRN'AMENTAL IRON STAIR--BA IL STRUCTURE.

Application'filed May 6,1926. Serial No. 107,0 8).

- My invention relatesto an ornamental iron stair rail structure, more particularly to the means of securing the separate members of the side railing of stairs together, and the objects of my invention are: first, to provlde a'stair-rail structure of this class in which the separate members are rigidly secured together withoutwelding, riveting or the like; second, to provide a stair rail structure of this class in which the vertical bar members are provided with recess portions made by a and which will not readily deteriorate or get out of order.

With these and other objects in view as my invention con will appear hereinafter, sists of certain novel features of construction, combination and arrangementof parts and portions as will be hereinafter described in detail and particularly set forthin the appended claims, reference being had to the accompanying drawings and to the characters'of reference thereon which form a part of this application in which:

Figure 1 is a side elevational 'view of the vertical and angular bars showing by solid lines the position. of the angular bar at approximately a right angle tothe perpendicular bar before being secured rigidly together, and showing by 'dotted lines the angular position of the bar when the members are rigidly secured in position and ready for use. Figure 2 is a perspective view of the vertical and angular bars vwith the angular bars shown slightly below the position in which they are securely positioned, and Fig' ure 3 is a fragmentary side elevational view of a stair rail constructed of a plurality of the perpendicular and angular bars in their assembled position.

Similar characters of reference refer to similar parts and portions throughout the several views of the drawings.

Thevertical bars -1, and angular bars 2,

constitute the principal'parts and portions I of my ornamental iron structure. The vertical bars 1. are preferably made of square material about one-half inch square.

desired. Theyare each provided in opposite sides with

notches

1 and 1 which are preferably made by a punch press. It will be noted that on the one side there is a thin oo However, they may be polygon shaped 1f,-

web 1, in each of the notchesand on one I side only. The angular bars 2 are preferably about one-quarter 4'?) by one (1'1) or one and one-quarter (1%") lnches and they are provided with square holes 2 which holes are made to conform to a cross-section of the bar 1 In this case it is shownsquare and is slightly larger than the bar so that the bars 2 will readily slide over the bar- 1; and the upper innercorner of the walls surrounding the hole 2' is adapted to fit into the notch 1 and the lower .inner corner is adapted to fit into the notch 1 in the bar 1 when the member 2. is positioned in the proper angular position to the memberl for forming the proper angle for the stairrail, as shown best in Figure 3 of the drawings it beingnoted that the notches 1" and 1" are positioned relatively to each other so as to provide approximately the proper angle of the stair rail when finished, it being noted that the web 1 is crushed when themem bers land 2 are forced to the angular position with each other as shown by solid andv dotted lines in Figure 1 of the drawing,the-

web providing for a-rigid, tight fit of the members 1 and 2relatively to each other where there is slight variation between the various steps of the stairs.

g It will be noted that the upper member 2 as shown'in Figure 3 of the drawingfits on the upper end of theuprights 1. Therefore the upper notch 1 is not complete, the upper portion being cut off Then over the upper member 2 is, provided a cover member 3 for covering the upper end. The lower end of the upright ordinarily restsupon the end of the steps of the stairs as shown best'in. Figure 3 of the drawing. When assembling this structure a plurality of the uprights 1 are placed in the holes 2of a plurality of the angular bars 2 positioned adjacent the

notches

1 and 1 in spaced relation. Then the structure is forced to the angular position by raising the ends of the bars 2 rela tively to the bars 1 and the bars 2interlocking with the barsl asshown in Figure 3 of the drawing, and by dotted lines in Figure 1 of the drawings, after which they are secured at their ends, providing a rigid interlocking ornamental iron structure without welding, riveting or the like. i

In order to furthersupport the structure annular members 4 may be interposed between theseparate members 1 and 2 and resting against said members as shown in Figure 3 of the drawings.

Though I have shown and described aparticular construction, combination and arrangement of parts and portions, I do not wish to be liini-ted'to this particular construction, combination and arrangement but desire to include in the scope of my invention the construction, combination and arrangement substantially as set forth in the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is: '1 In a structure of the class described, a plurality of polygon cross section bars pro;- vided with pairs of angular notches in "opposite sides of said bars and a plurality of 7 other bar s connecting each of the former and V tively to each other.

6. In a stair rail of the class described, a

plurality of square, perpendicular members, provided with a plurality of pairs of spaced notches in opposite sides thereof-and webs in:

said notches, and a plurality of spaced bars provided with holes adapted to. fit. loosely over said perpendicular bars andfit in said notches and to crush said webs when turned to an angular position on said, .bars.

means interposed between said perpendicular and angular bars for holding said bars in separate spaced relation and rigidly securing them together. r

In testimony whereof, I-have hereunto set my handat Los Angeles, California, this 7 f 29th day of April, 1926.
