2 Sheets-Sheet 42 INVENTOR ATTORNEY h. mayn'ess i MLUSWDE? b H1, Malines.. ne'real 511.1 f Sender@ z link between the balustrade rail and the balusterup special to conform to any required inclination ofthe rail as determined by the inclination of the steps for which the rail is to be used. It is the object of thel present invention to provide a standard rail with standard balusters which may be suppliedin anydesired lengths, or cut on the jobto the required length to assemble them at the time of their installation so that the balusters have a uniform length and the rail has substantially any required.A

inclination. The rail at its ends may-be connected with up-rights or posts by conventional fittings already available. Another object of the invention is to provide unif Y form upper and lower rails between which the balusters are placed. Another object of the invention is Yto provide.

means to lock the rail and baluster together and to prevent any relative movement between them and to provide a firm bearing of the rail upon the balusters so that they will furnish a firm support. Sincevthese balustrades can be assembled at the time of Ytheir erection they can be n transported in a knocked down condition yand require much less space for their transportation. j

Other'objects and advantages of the invention will be apparent from the following description and the accompanying drawings forming a part hereof and in which: Figure g1 is a balustrade shown in elevation made in accordance with this invention, showing in dotted lines the same balustrade swung to an inclined position.

Figure 2 is a cross-sectional view on an enlarged scale through the rail of Figure 1' on line .2 2 of Figure 4, showing the center of the balusters broken away.

Figure 3 is a sectional view through the rail on lin i.

Figure '4 is a top plan view on a reduced scale of the rail with the top section broken away on` line 4--4 of Figure 2.

Figure 5 is a sectional view on a reduced scale on line 5 5 of Figure 2.

In the drawings similar numerals refer to similar parts throughout the several views.

yThe hand rail 1 of the balustrade is preferably tubular Y and made of metal and can be either cast orv extruded and in cross-section as clearly shown in Figure 2. The same rail may be inverted asjat Z to formthe bottomrail of the balustrade. The rail -1 has a large inner opening 3 with strengthing ribs '4, 5, and 6'projecting therein from the upper'inner face of the rail. The lower portion of the rail has a slot 7 therein which in the form shown has spaced bearing faces 8 and 9 on each side of the slot with an open portion betweeny to lessen the requirement for metal in the rail. The lower section 10 of the inner opening 3 of the tubular rail 1 forms anges or shoulders projecting towards each other and within the slot 7 slide rectangularly cross-sectioned balusters 11 which snugly iit between the projections 8 and v9 forming annexes# I, I

The extreme ends of the balusters are formed on the ysarne radiusV 15 as the openings 12 and this radius on the pivots around the ends 15V and as the balusters pivot' around the normalbends or portions 14 of the rod 13. v

The plurality of bearing surfaces 8 and 9 on. each side of the baluster prevent therail from rocking around the ends of the balusters normal to the rail.`

It will be apparent that the space between surfaces 8 and 9 on each side of the rail could beclosed to present straight slotted walls tothe balustersif desired and that Y other modifications in the shape andconstruction of the parts could be made without departing from the invention as set forth in the following claims. v What is claimed as new and isdesired I O bersecured b Letters Patent is: l

I. A tubular rail having a longitudinal slot along one side thereof, a .plurality of balusters each having one end -tted into said slot and having an opening therein the axis of which extends cross-wise of the axis of the rail, a rodwithin the rail having spaced `zig-zag bends therein, certain of said bends extending cross-wise of the rod, the balusters rbeing engaged on the cross-wise bends of the rod through the said openings 'to anchor the ends ofthe balusters securely in the rail, the `balusters projecting from the rail slot, a plurality of balusters being anchored by Y zig-zag bends therein, certain of said bends extending n cross-wise of the rod over the anges within the tubular. rail,` a plurality of balusters each havingv one end fittedl Yinto said rail slot and having a' transverse opening ,therein engaged on the said cross-wise bends of the ro'd to secure the balusters in the rail, a plurality of'balustersr being secured by the rod.

3. In abalustrade, a tubular rail having a longitudinal slotalong one side-.thereof presenting spaced opposed flanges, 'a balusterfha'ving a transverse opening adjacent one end thereof, said end fitting securely in the rail slot, and a rod with spaced zig-zag bends therein, within the tubular rail, certain of said bends of the rod extending substantially normal tothe rail axis cross-wise of the rail and flanges and engaging the balusters through said openings on the said cross-wise bends to retain said ends of the balusters within the rail slot and space them therealong a plurality of balusters being retained by the rod.

4. TheV balustradeof claim E5, in which the rail slot flanges Vhave' faces contacting the balusters at a plurality `.of points lengthwise of the balusters to prevent rotation t of the rail relative thereto around the axis of the rail.

5. In a balustrade, a tubular rail having a longitudiinner shoulders on the slot sides, a plurality ofl .balusters ,nally extending 'slot *..along oneside thereof and presenting 5 rod extending cross-wise o fnand substantially normal to 10 the rail andslot and resting on said shoulders, said balusters being engaged through said openings on the Across-Wisegbends of the rod and securely pivotally held in the rail and spaced therealong by the rod,la plurality Vofbalus ters being heldby therod, thesspacingof the openings, v from the.y endsof-vthe balusters with the rod therethrough holding the balusters adjacent the top ofthe `tubular rail to `limit relativemovement between the rail and balusters.

6l A tubular rail having a longitudinal slot along one side thereof, a plurality of balustersA each having one end slidable in said slot and having an opening therein, the axis of which extends cross-wise of the axis of the rail, a rod with spaced zig-zag bends therein slidably tted into the tubular rail with certain of said bends extending substantially normal to and across and beyond the slot sides and having thereon ballis'ters mounted through said openings on the said ybends of the rod extending across the slot with the balusters projecting from the rai-l slot and beingY securely `locked' therein by the :said rod crosswise bendsprojecting beyond the Vsidesy of the slot'in the rail, a plurality of balusters being locked by the rod;
