` STAIB.
Application led November The present invention lrelates to stair constructions and has for its object to improve upon present-day stairs, to the end that their manufacture may be simplified` and their cost decreased, without in' any way impairing their efficiency. n The invention will be'explained in connection with the accompanying drawings, in whichFig. 1 is a vertical section through a stairway constructed in accordance with the present invention, thesection being taken substantially upon the line 1 1 of Fig. 4, looking in the direction of the arrows; Fig. 2 is a vertical section of a modification; Fig. 3 is a vertical section, upon a larger scale, taken upon the line 3-3 of Fig. 1, looking in the direction ofthe arrows; Fig. 4 is a similar' horizontal section, taken upon the line 4--4 of Fig. 1, looking upward in the direction of the arrows; Fig. 5 is a section similar to Fig. 3 of a modification; Fig. 6 is a perspective of the securing element shown in' Fig. 5; Fig. 7 is a section similar to Fig. 3 of a further modification; Fig. 8
is .a perspective of the modified securing element shown in Fig. 7; Fig. 9 is a section similar to Fig. 3 of another modification; Fig. 10 is a perspective of the modied securing element shown in Fig. 9; Fig. 11 is a section similar to Fig. 4 of still another modification; and Fig. 12 is a section similar to Fig. 4 of the modification shown in Fig. 9.
Three horizontal treads 2 of a stairway are illustrated in Figs. 1 and 2, each connected at their ends tosupports or stringers 4. `These stringers are usually mounted in vertical planes, and may be constituted of standard channels, plates, bent-plate channels, and the like. Only one Stringer 4 is illustrated, the views being broken away so as not to show the other Stringer. In Fig. 1, the treads are shown connected by risersA 6. `These risers may be panelled or plain. In the stairs of Figs. 2, the treads are separatedV from each other, without any connecting risers. If risers are employed, the riser 6 of each` tread may be caused to lap over the tread 2 of the next higher tread, as shown at 8, and the lapped parts may be secured together in any desired way. In the case of sheet-metal risers and treads, the securing means may consist of rivets or bolts 10. T'hese rivets or bolts, together with other projecting parts 34, 38 and the like, to be described hereinafter, may

help to anchor in place a marble, slate or other stonewear plate 12, as illustrated. The lapping parts 8 of the riser 6 may aid the performanceof this function. The bottom of the-wear plate is provided with openings to .receivev the projecting parts and is se-v cured to the tread by a layer of cement or other binder that fills in the projectionreceiving openings and the space above the tread 2 up to the level of the lapped-over portion 8 of the riser. This provides a substantial anchoring effect to hold the wear plate in place.v The separated treads shown in Fig. 2 may be made by bending a sheet metal plate 14 into oblong form, with the top of the oblong open atk 16. One or'both sides of the sheet may terminate at 18 and 19 at the top of the oblong. Preferably, however one of these sides is bent a small distance at 20 into vthe top plane of the oblong and both these sides may be so bent if desired. The oblong is then filled with concrete or other 'filler 22. Other types of stairs, too, may equally well be employed Without departing from the present invention.-
According to one embodiment of the invention, each tread is provided at each end with a pluralityof openings (two are illustrated, but three or more may be used), shown at 24 and 26, and the stringers are each provided with ay corresponding number of openings 28 and '30, the tread openings and the stringer openingsbeing correspondingly disposed inpairs 24, 28 and 26, 30. .An' eyed bolt 32 lextends through each stringer opening 28 and 30Vand a bolt 34 extends through the eye'36 of the eyed bolt and through the opening 24 or 26, as the case may be, ofthe tread. One or more nuts 38 serve to hold the bolt'34, the tread 2 and the eyed bolt 32 together. One `or more nuts 40 threaded on the threaded end of the eyed bolt 32 holds the latter in place. The tread is thus secured to the Stringer bythe direct interaction of the bolts 32 and 34, and rests upon the'eyed bolts 32. A yspacer bar or plate 42 is disposed between the tread 2 and the nuts 38, being provided with openings 44 and 46 toreceive the bolts 34. Thespaeer bar serves as a backing for the nuts 38, and also tov stillen the tread against transverse bending.
The above-described construction may, o course, be varied in many ways within the scope of the invention. Thus, instead Vof using the nut 40, the free end of the eyed bolt may be bent over against, and into-engagement with, the Stringer, exterior to the anglerbetween the tread and the support, as illustrated at 48, Figs. 7 and L8; or the bolts 32 and 34 may be replaced by a single bent rod, as shown at 50 in these same two views and 52 in Figs. 5 and 6, the arms 53 being continuous with ythe rest of the rod. The constructions Shown in Figs. to 8 are urther advantageous in that they present a better appearance from below the tread, in the angle between the tread and the support, Showing only the bent portion of the bent rod or=52. Equally eflicient is the modification shown in Fig. 11, comprising a single rod having threaded arms 54 and 56 extending through the Stringer openings 28 and 30, and having two bent eyes or openings 58 and 60 for alining with the tread openings 24 and 26 and the spacer bar openings and through which extend the bolts 34 tohold the parts together.
According to the modifications illustrated in Figs. 9, 10 and 12, a rod 62 is provided with an end upon whi'ehthe nut 40 is threaded, as in Figs. 3, 4, 5 and 11, or bent over an arm 53 continuous with the end portion, as in Figs. 5 to 8. Continuous with the arm 53 is, however, a portion 64 which bends at 66 down through an additional opening 68 in the tread 2, and then backward at 70 underneath the tread. A very secure locking effect is thus obtained. The openings 24 (or 26) and 68 are shown elongated in Fig. 9, to facilitate mountingA the rod 62 therein. The rod 62 is tirst inserted through the tread openings 24 and 68, then moved longitudinally through the Stringer' opening 28 (or 30), and the nut 40 is finally applied, locking the parts firmly together.
Other modifications, too, within the spirit and scope of the invention, will readily occur to persons Skilled in the art, and are intended to be expressed in the appended claims.
What'is claimed is: l. Stairs comprising a Stringer, a tread abutting against and extending outward at an angle from the Stringer, the St-ringer and the tread each having a plurality of openings,
