Claim!` (Cl. 273-82) This invention relates to an improved bowling pin and has for one of its principal objects the provision of a bowling pin, ten pin, or the'like, which shall combine all the advantages of a solid wooden pin while at the same time eliminat- 0 tion is the provision of a composite bowling pin or the like which is made up of a plurality oi parts, preferably a core, a head, and neck 0f wood, whereby the desired click of the ball against the pins in action is retained, While at the same time the expense of production of a solid wooden pin and the difficulties of manufacture thereof are considerably lessened.

Another important object of this invention is the provision, in a composite bowling pin or the like, of replaceable parts of some material other than wood which will combine or exceed the advantages of wood so far as resiliency and resistance to wear are concerned, while at the same time retaining the necessary weight per pin and also making suitable provision for the retention of the center of gravity of the pin in the same point as it is found in the wooden pins.

Other and further important objects of the invention will be apparent from the disclosures in the accompanying drawings and following speci cation.

The invention, in a preferred form, is illus trated in the drawings and hereinafter more fully described.

In the drawings:

Figure 1 is a vertical elevation, partlyV in section, of the improved composite bowling pin of this invention.

Figure 2 is a horizontal sectional view on the line 2-2 of Figure 1.

Figure 3 is a section on the line 3--3 of Figure l.

Figure 4 illustrates a modification of the invention.

Figure 5 shows a still further modification.

As shown in the drawings:

The reference numeral 10 indicates, generally, a core for the pin, which core is' preferably of a suitable wood or the like, and which has, integral therewith or attached thereto, a head and neck 12, also preferably of the same material, such as hard maple or'some similar wood. The dimensions of the combination core, head and neck are such that a considerably larger number of these parts may be obtained from a log or block of the Wood than would be possible if solid pins were made therefrom, while at the same time the desirable ring or click of the .pins in action is retained.

The core 10 may extend tothe bottom of the o pin ii' desired, or the same may be shortened as illustrated in the ligure and the required length be built up from the composition material applied to the core.

This composition is preferably in three pieces, 05

as indicated at le, 16, and 18 inFigure 1, the member le comprising the upper part oi the body oi the pin and having an inner cylindrical portion adapted to closely nt about the shank of the core 10, and is preferably glued or otherwise attached thereto in a desired or suitable manner.

It will be noted that an annular upwardly extending shoulder 20 4is provided at the upper end of the member i4., and the corresponding lower end oi the neck l2 is out away so as vto ilt snugly into this shoulder, this construction avoiding the possibility oi breakage at this point.

In order to afford the necessary lightness, while at the same time retaining the desired strength, a 30 plurality of radially extending webs 22 is provided in the member 14, these webs being best` illustrated in Figure 2. The number and size" `ci these webs may be varied as desired so as to produce a necessary result, and the material of 35 the elements 14, 16, and 18 may be ci any of a number oi suitable compositions now on the market, such as a phenol condensation product, fiber, celluloid, or some cellulose composition, or may be composed of some fibrous or textile material such as strawboard, canvas, or the like, impregnated with a suitable composition which will afford the necessary strength and resiliency.

The lower element 16 is preferably shaped as shown in Figure l but may have a cylindrical V opening throughout its length allowing the core 10 to extend therethrough to the bottom thereof. Suitable air spaces are provided in the member 16 by means of webs or the like, similar to those illustrated in Figure 2. This member is likewise glued or otherwise fastened to the core, and,

if desired, may be keyed thereon by means of a wedge or the like 24.

There is preferably provided between the members 14 and 16 ,a horizontally extending disk 18 105 ings 26, which may be of any desired size and U0 properly position the center of gravity ofthe bln'.

As illustrated, the inner and outerlperipherie's of the disk 18 are provided with shoulders 28 and 30, respectively, whereby a more accurate fitting to corresponding portions of the members 14 and 16 may be provided; but this feature may be eliminated if desired without affecting the qualities of the pin in any way. f

A modification of the invention is illustrated in Figure 4, wherein a core 40 is either built onto or formed integral with the head and neck 42, the

lcombination being provided with'V a squared shoulder 44 at their point of junction, and about this core is built up a body comprising a plurality of layers of fiber or some similar material, as shown .in 46. 'I'he upper layerv 48 is shaped to correspond to the `iunction orshoulder 44, where; by breakageat this point is minimized, and the bottom element may present a continuous under-surface having a slight recess 52 therein for spotting or the like, and a socket 54 in its upper face for the reception of the lower end of the core 40.` These layersof fiber may be 'cut away or recessed at suitable points, as shown at 56, and may be drilled, as shown at 57, to provide lightness and also air spaces for resiliency. These to size and position, that the center of gravity In Figure 5 is illustrated still a further modifi-` cation of a combined core d0 and head and neck 82, wherein a junction of these parts is further strengthened by the use of a metallic sleeve 64 which can be fitted around the upper end of the neck 60, and which may further cooperate with a suitable metallic washer or the like 66/ which fits snugly against the lower end of the neck, thereby reinforcing the same. In this ngure the core 60 is shown as extending completely throughout the length of the pin and with-.a lrecess 60 provided in its bottom for spotting or setting purposes, as in the usual construction.

4 It willbe evident that herein is provided a composite pin for bowling or the like which will meet all the requirements of the solid wooden pins heretofore considered necessary, while at the same time afford a cheaper and more durable construction and one which is composed of replaceable or renewable parts, thereby rendering the same susceptible of repairing after damage through length of service, while at the same time retaining the original head,nec k and core which provide the desirable playing qualities.

I am aware that many changes may be made and numerous details in construction varied throughout a wide range, without departing from :,ceasvs l l the principles of this invention, and I therefore do not purpose limiting the patent granted hereon otherwise than asl necessitated by the prior art.

I claim as my invention:

1. A composite bowling pin, including a head, neck, andv core of wood, with a shoulder at the junction of the core and neck, and reinforcing means for said junction, said reinforcing means comprising a metallic sleeve and washer, and a body of fibrous material built up onthe core, said body having air cavities therein.

2.,` A bowling pin construction comprising the combination of an axially disposed wooden spinxdle having a portion .shaped to form the pin head and neck, composition shell members each encompassing and secured to the spindle below the neck and having their external surfaces 'shaped' to form the ldesiredsurface contour of thepin'body, and a girth ring secured to the compassing and secured tothe spindle and se.

cured to and aiording the adjacent shell members marginal vsupport radially of thepin, said shell members being shaped externally to vform the desired contour of. the pin body.
