3 Claims. ,(ol. 273-45) My invention refers to improvements the manufacture of billiards and pool-table and more particularly to'the construction of thebed as well as the parts connected with'the same.

.5 Billiards and similar appliances usually comprise a wooden base-structure, a suitably reinforced frame supported .by the former and a playing-plate or bed, forwhich slate, marble or similar substances are used and which is supported by a frame-structure.

In some cases a wooden frame-structure duly reinforced in longitudinal and transverse direction is used for directly supporting the plate or bed., Base-struc tures made of a'metal such asiron have also been suggested heretofore.

The cushion holders which, when made of wood, must be very voluminous, are usually connected with the plate or bed by means of screws.

Now on beds made of marble the rollingball produces a hard sound and forthis reason billiards have been usually equipped witha bed or playing-plate of slate; Slate, however, is a comparatively soft material of laminated structure and therefore very liable to become damaged, which is particularly the case during transport. Nevertheless slate is generally preferred and chiefly employed in the construction of billiards beds orplates mainly because the connection of the same with the cushion or the abutting cushwhich is possible only with the aid of nuts inbores for the screw threads break away and become inaccurate in consequence of the parts concerned being repeatedly taken to pieces, when the cloth is renewed or its proper tension is reestablished. a r

The above-mentioned various drawbacks of the known complicated wooden or metallic billiard base-structures as well as of the fastening of the playing-plate orbed are obviated according to the present invention thereby, that the playingsurface, plate or bed, upon which the game is executed, is made of metal, as for instance castiron, steel, light metal ora metal alloy and of course afterwards covered with cloth'in the usual manner. The metal plate may be provided with reinforcing ribs and may consist of one piece or may be composed of a plurality of pieces.

Theinvention is illustrated diagrammatically and by way of examplein the accompanying surface of the bed. 1 areprojections 5 (Figs.

The rubber cushions 3 are inserted into the frame formed by said ledges, as shown in Fig. 3. Theprofile of the side rails may be chosen as desired. On the bottom 1 and 3) to which the legs 6 are secured by means of screws 10. The legs may consist of any desired material. The playing plate may also consist of several parts.

The advantages presented by this construction, as well as by the use of metal for the playing plate and for the cushion frame are extraordinarily numerous.

Slate plates of such a quality and such a thickness as requisite for the purpose in view are obtainable only in very few countries, whereas there are nearly everywhere foundries and machine works, wheremetal plate suited for said purpose can be made.

Assembling the members constituting my pres- 35 ent improved billiard is very simple and can be effected also by unskilled hands. I

In the case of a large billiard it is possible to reduce the weight thereof considerably by using a light metal for the playing bed and by omitting all separate supporting members'for said bed,

which is rendered possible by thelparticular construction described; that lesser weight facilitates cushions, retensioning the cloth, and the like can be carried out far more easily and in a shorter, time than is possible with billiards of anyof the known constructions.

No other material than metal renders it posemployed for said beds.

whatever, the balls run noiselessly, and the very,

sible to manufacture the playing plate so plane, accurate, properly right-angled, and lasting.

The metallic playingfbedpresents unforeseen advantages over all other materials up to now There is no resonance the assemblage of the members constituting the billiard is greatly facilitated-landing) insertedinuts are required.
