BILLIARD-TABLE.

Speeication of Letters Patent.

Patented May 1l, 1909.

Application led December 5, 1907. Serial No. 1li-05,289.

To all whom it may concern:

Be it known that l, Kani. ALBERT AUGUST Bnliciinn, of the city of Toronto, in the county of York and Province of Ontario, Canada, have invented certain new and useful Improvements in Billiard-"fables, and l hereby declare that the following is a full, clear, and exact description of the same.

The present invention relates to the construction of a billiard table bed comprising several table bed sections made of a concrete mixture and maintained in their fixed position to each other by dowel pins contained in dowel sockets inserted in their adjoining edges, and by nuts inserted in their outer edges to receive the bolts, by which the table bed sections are secured to the billiard table cushion.

For an understanding of the invention reference is to be had to the following description and to the accompanying drawings in which:-

Figure 1, is a plan of a billiard table bed consisting of three sections. Fig. 2, is a horilrontal section showing the location of the dowel sockets and pins and the cushion bolts and nuts. Fig. 3, is a vertical section showing a screw for securing the table bed sections to the under framing of the billiard table. Fig. 4, is a section of part of two adjoining table bed sections on a larger scale than Fig. 2. Fig. 5, is a section of two dowel sockets and a dowel pin on a larger scale than in the preceding gures, and, Fig. 6, is a section of a cushion bolt and nut.

Like characters of reference refer to like parts throughout the specification and drawings.

The billiard table bed as shown in the accompanying drawings consists of three table bed sections c a a. In molding the table bed the table bed sections a a are formed at their outer corners with pocket apertures t' and the middle section a is formed at the middle of its outer sides with pocket apertures i but in certain classes of billiard tables these pocket apertures may be omitted. The table bed sections are preferably made of a mixture of cement and a refractory material such as sand and crushed slate, or stone, ground to a very fine mesh and preferably in proportion of about one part of cement to one part of sand and two parts of crushed stone intimately mixed and bonded together. In molding the table bed sect-ions a metal netting y is placed in the concrete mixture, the metal netting yg/ being apertured when necessary to form the corner and middle pockets in the table lied sections.

For a billiard table of ordinary dimensions three nuts 7c are employed along each. end and six nuts along each side of the billiard table bed, being placed in the concrete mixture during the molding of the table bed sections. The purpose of the nuts la' is to receive the cushion bolts m by which the table bed sections are fastened to the cushion of the billiard table framing. To prevent the nuts k turning in the table bed sections the former are preferably of a multi-facet formation and to revent them being withdrawn from the ta le bed sections they are of a tapering shape and are formed with projecting lugs 0 which become embedded in the concrete mixture beyond the body of the nuts to securely hold them in their lixed position. At the middle of the adjoining sides of the table bed sections are dowel sockets g and q centered to receive the dowel pins r which maintain the middle table bed section in a fixed position to the outer table bed sections when the table bed sections are assembled. The dowel sockets are formed with peripheral grooves g to receive some of the concrete mixture which prevents their withdrawal. The bore of the dowel socket Q is `preferably screw threaded to receive the screw threaded end r of the dowel pin r, and the bore of the dowel socket g is smooth to receive the smooth end r" of the dowel pin. The table bed sections are secured to the under framing of the billiard table by bolts or screws s which extend through the apertures t, the apertures t being counter-sunk to receive the heads of the bolts or screws s. When the table bed sections have been cast and the concrete mixture has set their adjoining edges are matched by grinding or by other means until a perfect jointis formed and their surfaces are then ground and polished until the playing surface is perfectly even and smooth. Then the table bed sections are assembled on the billiard table framing they are locked to the billiard table cushion by the bolts m which enter the nuts le and to the under framing by the screws s which securely fasten the table bed sections against lateral and longitudinal displacement, the dowel pins and sockets holding the adjoining edges of the table bed sections properly matched, and maintaining their top surface in the same even plane.

Havin(r thus fully described my invention What I claim as new and desire to secure by Letters Patent is l A billiard table comprising several separate table bed sections constructed of concrete material, nuts for the cushion bolts embedded inthe outer sides of the table bed sections, dowel sockets embedded in the adjoining sides of the table bed sections registering with one another, and doWel pins contained inthe idowel sockets to hold the table bed sections positioned.

2. vA billiard table comprising several separate table bed sections constructed of concrete material, nuts for the cush-ion bolts embedded in the outer sides of the ltable bed sections, dowel sockets embedded in the advsections positioned, and means for 'fastening embedded in the adjoining sides of the table Y bed sections registering with one another, doWel ins contained in the doWel sockets to hold te table bed sections positioned relatively to each other, the table bed sections being apertured to receive the fastening means by which they are secured to the uni der framing of the billiard table,
