United States I Patent 2,992,001 OUTDOOR BOWLING ALLEY Cyrus Y. Ferris, Jr., Barre, Vt., assignor to Rock of Ages Corporation, Barre, Vt., a corporation of Vermont Filed Oct. 16, 1958, Ser. No. 767,621 Claims. (Cl. 273-51) This invention relates to a construction for an outdoor bowling alley and in particular relates to an outdoor bowling alley made of granite.

Outdoor bowling alleys have been constructed in the past of either wood or concrete. The outdoor bowling alleys surfaced in wood have been plagued with warping and buckling by virtue of the exposure of the wood to the elements and this has resulted in a surface that was entirely too rough and hence unsatisfactory for any degree of enjoyable competition. Also, no satisfactory manner of compensating for the expansion and contraction at each of the joints along the surface of the alley has been devised.

The outdoor bowling alleys surfaced with concrete, on the other hand, have proven to be unsatisfactory primarily because of the relatively high temperature coefficient of linear expansion of the concrete which produces cracks in the surface with fluctuations in temperature. Exposure to wind and rain also makes it very difficult to obtain and maintain a smooth surface on such an outdoor bowling alley. Also, the cement surface tends to have an abrasive effect on the plastic balls which are used.

It has been discovered according to the present invention that by making the bowling surface from two slabs of granite in a construction providing for expansion only at the ends of the granite slabs these problems may be obviated. Furthermore, this invention includes a novel bulfer to be used in connection with the permanent installation on the granite bowling alley. It has been found that if the surface is not buffed it will have an abrasive effect on the plastic balls which are used. Moreover, it has been discovered that this bulling must be performed at the site of the permanent installations because the heat generated in the bufiing operation causes some slight vitrification of the granite slabs which in the course of of shipping results in small surface cracks which will not withstand the pounding and rolling of the bowling ball. Means are also provided to establish and maintain the granite slabs level so that the alleys shall not be adversely affected by ground settling, buckling produced by frost or. other factors causing elevation changes in the ground. 7 Accordingly, it is a primary object of the present invention to provide an outdoor bowling alley that will not be adversely alfected by changes in temperature, wind, rain, and the elements. It is another object of the present invention to provide an outdoor bowling alley that may be maintained in a smooth and level condition. It is a further object of the present invention to provide a novel means for maintaining the bowling alleys smooth. It is an additional object of the invention to provide means for compensating for ground settling or swelling.

These and further objects and advantages of the invention will become more apparent upon reference to the following specification and claims and appended. drawings wherein:

FIGURE 15 is an end view of the bufier of FIG- URE 13. v

Referring now to FIGURE '1 of the drawings, an 'approach to the bowling alley is shown at 20. Granite slabs 22 and 24 are placed on a concrete foundation indicated generally at 28. The slabs 22 and 24 are aligned and in substantially abutting relationship so as to form a joint 26. The juncture between the bowling alley approach 20 and the first slab 22 is indicated at 30. A pit 32 is shown at the far end of the alley remote from the approach 20. V FIGURES 2 through 6 disclose some of the details of the concrete foundation 28 and the manner in which it supports the granite slabs 22, 24 and the approach 20. Wall-like legs 40 are adapted to extend downwardly into the earth. A footing or flanged portion 34 is disposed at the base of each leg 40 which legs extend about the entire periphery of the alley so as to completely encircle the foundation. A shoulder 36, shown in FIGURE 3, engages three sides of the approach end 20. Referring to FIGURE 4 there is seen a shoulder 42 which engages the sides of the slabs 22 and 24 and is somewhat lower than the shoulder 36 at the approach end 20. Referring a grout or other suitable mortar 38 is placed between the concrete foundation 28 and the granite slab 22, 24 and the approach 20.

It will be apparent that FIGURES 1-6 show .a bowling alley without gutters, ball return, pin spotters and other standard equipment and it is to be expressly understood that such standard accessories form no part of the present invention. These accessories may be purchased from a bowling equipment manufacturer, such as the Brunswick Balke Collender Company. a L f Reference is now made to FIGURES 7-9 which show the manner of establishing a preferred type of joint be tween the slabs 22 and'24. A pair of angle plates designated generally at 48 is placed on each side of the slabs 22, 24 so as to straddle the'joint 26. Each angle plate 48 is shown to comprise a leg 50 which contactsthe sides of the granite slabs and a leg 52 which is at right angles to the sides of the granite slabs. A pin 54 is shown to extend through a bore in each leg 50 and into the adjacent granite slab. A threaded stud 56 passes through a bore in each of the legs 52 and each stud 56 is placed under tension by tightening a pair of nuts 58. A rigid plate 62, preferably of steel, underlies the granite slabs 22 and 24 on a horizontally disposed pol:

In'zthe operation of the buffer an operator grasps the handle 96 and oscillates. the buffing disc 94 which pivots with the horizontal pivot member 86 about the pivot pin 8-8. The-'buffing disc 94 is construeted of any standard granite bufling abrasive and is adapted to be used on the granite slabs 22 and 24 prior to the installation of the acces sory bo wlin g equipment. v r

The joit between the approach end '20 and the first granite slab 22 is approximately brie-half inch in' width and 'is filled with pitch "or other suitable flexible compound. This permits this end of slab 22 to 'ex: pand. Slab 24 is completely unrestrained at "its end remote from the joint 26. Therefore, any'ariiouht'of expansion is possible fortl'iei'grani'te slab 24.
