length than the strips comprised in the intermediate sections, due to the indented ends of the sections where the sections are connected together.

The alley floor is constructed of strips 34, preferably of yellow pine, set on edge and side strips 35, which preferably are thicker rthan The strips 34 and 35 forming each section of the floor are connected together by bolts 36 which extend through aligned transverse openings in said strips, and the side strips 35,are recessed to receive the heads and nuts of the said bolts. At the meeting ends ofthe sections alternate strips extend beyond the intermediate strips, and the projecting strips of one Y section enter the recesses between the project-l ing strips of the other section, not only breaking joints but insuring a smooth, even surface and accurate alignment of the sections. The sections may therefore be made up at'the factory 'and be shipped ready to be laid upon the V3'7V may be bolted to the horizontal flanges ofthe e cross bars 21 and the flooring maybe secured in place in its supporting frame as by means of lagscrews 36a extending through openings in the` horizontal yflanges of the cross bars 2l into the lower sides of said sections. The protecting bars 37 lare in sections of approximately uniform length, y

theaggregate length of same being rthe'same as f the aggregate length of the four sections of f flooring. The protecting bars areeach therefore of a different length than that of the floor sections which additionally insures alignment of the oor sections. l

The floor of the players platform is Wider than the alley door and is formed of strips similarly to the alley floor. The strips 38 constituting this floor are of equal length and vall terminate in straight transverse lines at the ends of the platform. The strips are assembled and secured together by bolts 39 extending through transverse aligned openings Vin said strips and the side bars 27, as best shown in Figure 4.

The box or pit in which the pins are set up comprises side walls 40 resting at their forward ends on the horizontal flanges of the guard rails v25 (see Figs. `1' and5) The'box also comprises a floor 41 and an end wall 42. A board 43 encloses the front end of the box, while exposing at least the upper portion of the end of the runway. The ball-return trough, which extends throughout the length of the alley, comprises two parallelV angle-iron side bars 44 yconnected by yokes 45` (Figures 3 and 10). The yokes 45 are supported on standards 46, which in turn are carried by the lateral extensions 23 rof the cross bars 21 and the brackets 33. Inthe bottom of eachyoke is a plate 48, and eachof the plates carries an inverted channel bar 47, which forms the bottom of the skeletontrough.` 4At the pit end beyond the'runway the yokes are carried by straps 49 secured to the sides 40 of the pit or box. The ends of the trough carry transverse bars 50 in which are mounted buff` fers 51.

A standard 53 extending upwardly from one of the side plates 27 carries a score box 52.

The runway and platform are supported by jacks comprising base-portions 54, screw-threaded portions 55, and nuts 57 on said screw-threaded portions. The screw-threaded portions are Y iiattened adjacent their upper ends, as at 56, and such flattened portions `are secured to the 1 cross bars 21 and 28 by bolts 58. v

What I claim is: Y

l. A portable bowling alley comprising a sectional supporting fraine, each section comprising side bars and angleiron cross bars, the vertical l flanges 'of the cross bars being cut away where rthey meet the end bars and the horizontal i'ianges extending across and beyond the side bars, the extended portions being offset at their ends to form elevated seats, and angle-iron guardrails l supported on said seats.

2. A portable bowling alley, comprising a sectional runway, angle-iron guard bars spaced from the sides of said runway, each of said guard bars zontal ange of one of said guard bars, an end 1` wall and a floor. e Y

3. A portable'bowling alley, comprising a seck tional runway, a pair of guard bars supported,A

=portion of one of said guard bars which projects beyond said runway, a floor and an end Wall carried respectivelyby said side walls.Y tigo ALFONSO H. DUNLAP.v
