BOWLING-ALLEY.

SPECIFICATION forming part f Letters Patent N0. 543,141, dated July 23, 1895.

l Application led December 5, 1894. Serial No. 530,872. (No model.)

To @ZZ whom it may concern:

Be it known that I, JOHN A. RIEPER, of New York city, New York, have invented an Improved Bowling-Alley, of which the following is a specification.

This invention relates to a bowling-alley composed'ofrportable sections that may be readily fitted together and'leveled. Thus the bowling-alley may be put up in a short time and without the great care and expense necessary to build the usual permanent alleys.

In the accompanying drawings, Figure l is a side view of my improved bowling-alley with the gutter partially broken away. Fig. 2 is a plan of the alley with one of the gutters partly removed; Fig. 3, a perspective view of 'a joint between two adjoining sections; Fig. 4, an end view of one of the sections; Fig. 5, a longitudinal section on line 5, Fig. 4; andFig 6, a similar section on line 6, 6, Fig. 4.

My improved bowlingalley is composed of a series of portable sections A B C D, doc., each made of convenient length and all adaptedto be so iitted together that when connected they form a continuous alley of proper length. Each section is composed, essentially, of a foundation, a superposed bed, and transverse end girders that are adapted to interlock with the end girders ofthe adjoining sections.

The foundation is composed of two or more These free ends of the girders are perforated for the reception of screw-bolts e, that engage tapped door-plates e', let into or supported upon the floor of the building. Nuts e2 es,

carried by the screw-bolts, serve to respectr ively support the girder and to relieve the lower end of the bolt from strain. The two girders c d, secured to the adjacent ends of every two adjoining sections, are of slightlydifferent construction and are so made as to form. a lock-joint between them.

Each girder is provided with a horizontal top flange and a horizontal bottom flange to form, in effect, a V-beam adapted for the reception of the reduced ends of beams a. The girders are attached to the beams by the screw-bolts f, Fig. 5, that pass through a longitudinal bore of the beams and are held in place by 4nuts f secured within mortises a3. The girder c is provided on its top flange with a nose c', which is set back from the edge of the girder and has an undercut outer'edge c2.

The girder d is provided on its top flange with a nose d', which projects outwardly beyond the edge of the girder and has a beveled outer edge d2. When the two sections A B are put together, the nose d will project over the top iiange of girder c, Fig. 6, and enter beneath the beveled edge c2 of nose c. Inv this'way the girders c d are interlocked in such a way that any vertical motion of one girder will be transmitted to the other girder,--/"Jl and thus the girders will always maintain precisely the same level. That this is of the utmost importance at the joint between the sec-v tions A B is evident.

To prevent any possible displacement, the girders o d may be connected by screws g at their outwardly-projecting ends.

In order to level the alley, the nuts e2 eare slackened, the bolts e raised or lowered, and then the nuts are again tightened, when the alley will be securely supported and connect` ed in all its parts.

To increase the stability of the structure,

the cross-beams a should be supported atv their free ends by additional screw-bolts h, placed at suitable distances apart and engaging the tapped Hoor-plates h.

At the sides of the alley I secure to the iioor of the building the longitudinal gutter-rails i, having an offset to support the outer edge ofthe gutterboards, the inner edge of which is supported upon the projecting ends of the girders c d. j

It will be seen that my improved bowlingalley presents a compact structure, which may be readily put up or knocked down, and which locking laterally projecting end girders, floor plates, and screw bolts that secure the girders to the floor plates, substantially as specified.

4. The combination in a bowling alley of the following elements: foundation beams, floor boards supported thereby, laterally pro jecting 'interlocking girders, screw bolts engaging the girders, floor plates engaged by the screw bolts, and gutters that are supported by the free ends of the girders, substantially as specified.
