This invention relates to bowling or ten pins and the method of making them.

A primary object of the invention is to so construct such a pin that its wearing qualities will be greatly increased and which will yet be cheap to manufacture and which will produce the ring which heretofore has only been produced from pins made of wood.

Another object of the invention is to construct a composition pin which while shock absorbing and resilient is suficiently heavy to meet the requirements and which will withstand the shock incident to the hitting or" the pin by the ball.

In carrying out these objects, the invention is susceptible of a wide range of modification without departing from the spirit or sacrificing any of the advantages of the claimed invention; there being shown in the drawings .for illustrative purposes a preferred and practical form, in which.

In the accompanying drawings: Figure 1 represents a side elevation partly in longitudinal section of a pin constructed in accordance with this invention;

Fig. 2 is a transverse section taken on the line 22 of Fig. 1; and

Fig. 3 is a similar view taken on the line 3-3 of Fig. l.

In the construction of the pin constituting this invention and which is here numbered 1, a wooden core 2 extends longitudinally through thebarrel or body portion of the pin and has made integral therewith a neck 3 and a head 4:. The neck 3 flares toward the lower end and has a shoulder 5 at its junction with the core 2. y

The barrel and bottom of the pin are built up of vulcanized fiber board washers, someof which are apertured and some not, and which are moulded into form and then pressed on and glued. Any desired number of these washers may be employed, ten being here shown, the top and bottom washers 6 and 7, respectively, and the middle washer 8 being made solid throughout except where they are equipped with an opening to fit the core 2 as is shown clearly in the drawing.

The three washers 9, l0 and 11 arranged above the solid central washer 8 and the :four washers 12, 13, 14- and 15 arranged below said washer 8 are apertured to provide air cavities rendering the pin resilient and shock absorbin and also operate to lighten the weight 0' the-pin. The number and size of the air cavities in a fiber washer being determined by the amount of fiber that might be ranged about mid-way the length or the barrel or body of the pin is located at the spot where the pin ishit by the ball and it is necessary that this section of the pin be solid so as to withstand the shock incident to the strike.

The fiber discs or washers have fiat fittin faces at their peripheries which are curve or bevelled so that when assembled they will form the proper shape of the pin which is buged atits center and tapers towards its en s. s I

A wooden core and head are provided so as to obtain the desired ring of the pin when struck by a ball since wood is the onl known materialothat willaccomplish this unction. The barrel and bottom being made of vulcanized fiber board is much more durable than wood, hence the life of the pin is greatly prolonged, since the barrel and bottom are subject to the hardest wear.

The cost of producing a composition pin of this character is less than that of producing a solid wooden pin such as is now used.

Without further description it is thought that the references and advantages of the invention will be readily apparent to those skilled in the art, and it will, of course, be understood that changes in the form, proportion and minor details of construction may be resorted to, without departing from the spirit of the invention or its scope as claimed.

it claim:

l. A composite bowling pin comprising ahead, neck and core of wood with a shoulder at the junction of the core and neck, a plurality of fiber boa-rd washers strung on said core and arranged in abutting relation, secured to each other and to the core, some of said washers having air cavities therein.

2. A bowling pin having a body formed of fiber board with air cavities formed at intervals therein to render the pih light and shock absorbing said body being provided with a solid portlon at the center or striking part of the body to resist the strains of the ball. 5 3. A bowling pin comprising a wooden head and neck with a core extending longitudinally from the neck and having a shoulder formed at the junction with the neck, a

plurality of fiber washers arranged on said I 10 core secured to each other and to the core,

some of said washers having air pockets therein and some being made solid.

4. A bowling pin comprising a wooden head and neck, with a wooden core extendin 1ongitudinally from the neck, a pluralit o fiber washers arranged on said core an secured to each other and to the core, some of said washers having air pockets therein and some being made solid.
