COLLENDER'S IMPROVED BILLIARD TABLE.

In the accompanying engravings, we illustrate two important

improvements in the construction of billiard tables, which have

recently been devised by Mr. H. W. Collender, the well known billiard

table manufacturer of this city. The first, which is represented in

Fig. 1, relates to the construction of the bed-supporting frame, and

aims to render the same stronger while cheapening its manufacture.

In putting together the body and framework of the table, the usual

practice is to cut away the stock of the cross beam and longitudinal

beam, and halve them together. Longitudinal grooves are also formed on

the inner surface of the side and "broad rails," to accommodate tenons

on the ends of the cross beams; and the latter are secured in place

by bolts fastening their ends to the broad rails. Mr. Collender claims

that, by this mode of construction, not only are the cross beams

weakened by being halved together, but the broad rails are also

weakened by the cutting away of this stock near the middle to effect

the framing into them of the ends of the cross beams.

[Illustration: Fig 1, billiard table support frame]

From Fig. 1, it will be seen that the cross beam, A, is combined with

the side broad rails in the following manner: Upon the inner face of

each broad rail is secured a cast iron socket piece, B, into which

fits one end of the cross beam, A. From said beam the bolt, C, passes

through the shoe, B, and is secured by a nut, D, let into the stock of

the broad rail. The shoe, B, has lugs which enter the broad rail; and

the aperture in it, through which the bolt passes, is made oblong to

admit of the drawing of the parts together after the insertion of the

bolt. Upon the sides of the cross beam near the middle, and directly

opposite each other, are two shoes, E; these have no bolt holes. In

them are placed the adjacent ends of the longitudinal beams, F, the

other extremities of which are seated in shoes on the broad rails.

The shoes, E, have their lugs of such a length, compared with the

thickness of cross beam, A, that when put in place on said beam said

lugs will come together. The advantage of this is that, should the

beam, A, shrink in width, the shoes on each side of it will still

maintain their proper relation to form immovable abutments for the

ends of pieces, F. This construction allows of shorter stuff being

used in the manufacture, and renders the framework stronger.

[Illustration: Figure 2, billiard table frame corner]

In Fig. 2 is illustrated a new method of forming the corners of the

table. Hitherto it has been customary to use corner blocks, of various

sizes according to the dimensions of the table, located one at each

corner. Into these the broad rails were framed and secured. To this

arrangement Mr. Collender adduces a long category of objections, based

on the possibility of the weight of the bed being thrown on these

blocks in case of shrinkage of the frame, on the fact that the corner

of the table bed must necessarily be left without any support where

it extends over the upper end of the corner block, and also that in

a bevel table, in which the area of the top of the corner block is

unavoidably much greater than that of the top of the corner block of

a vertical-sided table, a large portion of the table bed will be left

without any support.

The new device consists of a cast iron union plate, G, which is bolted

to the leg as shown. The broad rails and casting are securely fastened

by the bolt, H. It will be seen that this bolt, passing through the

end of one broad rail, and into a nut let into the other rail,

will securely draw and hold together the ends of said rails and the

interposed metal plate clamped between them, and that as the plain

ends of the wooden rails just fit (widthwise) between the projecting

heads on the edges of said interposed plate, the latter will form a

sort of housing for the ends of the rails. And it will be understood

that in this construction not only does the bead on the outer edge of

the plate overlap the edges of the rails and form a neat and durable

corner finish to the body, but the broad rails being bolted together

in the direction of the grain of the wood with only an interposed

metal plate, there will be no tendency to a loosening of the union of

the parts of the frame. The main importance of this invention rests

in the idea of dispensing with the usual corner blocks, and thus

permitting the top edges of the broad rails, on which the bed rests,

to practically come together and afford a perfect support to the bed

clear out to the corners of the latter; at the same time the whole

structure is rendered stronger and more durable with less weight of

material.

These inventions are the subject of separate patents, that of the

first being dated April 4, 1876, and of the second, November 16, 1875.
