To 15 whom it may concern.-
Be 1t known that 1, WILLIAM R. llmcrrr a subject of the King of Great Britain, and
a resident of. Belleville, county of Essex and State of New Jersey, have invented new and useful Improvements in Playing-Balls of which the following is a specification.
The object of the invention is to construct a playing ball with means which will place the hall under control in all departments of the gan'ie in which. it is employed.
According to my invention the ball may be provided: with a: center having a heavy liquid that will aid its flight.
' The invention preferably relates to that class of playing-balls that are (specially adapted for the purpose of golfing and which have a liquid center. In performing my invention a playing-ball is constructed with a bag or container within which there are liquids of different specific gravities. The weight of the ball is dependent to a certain extent upon the particular combination of: liquids chosen and the amount of each liquid employed. With the proper selection of liquids a ball may be made comparatively heavy; that is the ball may be what is known as a non-floating ball or the ball may be made comparatively light, that is the ball.
may be what is known as the floating type of ball.
As illustrating the manner in which the invention may be realized reference is made to the accompanying drawing which forms a part of this specification and in which drawing- Figure 1 illustrates a playing-ball partially broken away so asto show its interior construction. Fig. 2 shows a core partially broken away which is utilized in the ball shown in Fig. 1.
The playing-ball comprises a bag or container A that is filled with incompressible liquids of diilerent specific gravities as B and F, B being the lighter liquid and F the heavier liquid. The bag or container A and the liquid thus constitute the nucleus'or core of the ball. Around this core there is preferably wound under a high degree of tension a rubber tape that may be for example approximately one inch in width. This rubber tape is comparatively thin. and when wound under a high degree of tension imparts great pressure upon the liquid in the bag or container A. The windings of tape are indicated by the reference character Q and around these windings of tape there is wound under a high degree of tension what may -be considered a thread of rubber which thread before winding may be approximately three thirty-seconds of an inch in width. These windings of rubber thread are indicated by the reference character l3. Finally there is placed upon and around these windings any suitable wear-resisting casing E, for example of gutta percha, which constitutes the exterior portion of theball. The bag or container' A is made so as to comprise the rubber portion a and fabric portion a) that con stitutes arcinforcing member or protecting member for the rubber in the casing.
It has been. previously indicated that any one of several combinations of liquids may be employed within the bag or container A, dependent upon the kind of ball ultimately desired. For example, it a heavy ball is desired the liquid within the bag or container A may comprise atcr for the lighter liquid 13 and mercury for the heavier liquid F. It a ball of a difi erent weight is'desircd acetylene tctrabromid may be employed for the heavier liquid, and amyl formate tor the ligl'itcr liquid. The former of these has a specific gravity of approximately and the latter a specific gravity ot approximately .868. If a floating ball is desired heptanc may be employed for the lighter liquid and amyl formats for the heavier liquid. The specific gravity of hcptanc is approximately .689 While that of amyl for-mate as above indicated is approximately .868. Other coinbinations which might be used are as follows but it will be understood that a large number of combinations could be employed. other than those indicated in this specification. Methyl salicylate and ainyl formats the relative specific gravities of which are respectively 1.185 and .868. Heptane and water the relative specific gravities of which are approximately .689 and 1.00.
The liquids in the different sets of combinations above referred to are not soluble in each other; in other words they are of such a character that they do not tend to mix but on the other'hand tend to separate and remain separated with the lighter liquid lloating' on the heavier liquid, and the expression do not mix with each other is intended to convey the meaning that these liquids will tend to separateand tend to remain sepa rated if allowed to do so.
it will be manifest that the invention may be embodied 'in'various forms and modifications Without departing from the spirit and scope thereof. b
What I claim is:
1. A playing-ball comprising in combination a bag or container filled with a plurality of liquids of: different specific gravities, windings of rubber surrounding said bag, and a Wear-resisting casing on the exterior of said windings.
2. A playing-ball comprising in combination a bag or container filled with liquids of different specificigraviti'es which liquids are of such a character that they tend to separate from eachother, rubber windings surrounding said bag or container, and Wearresisting casing on the exterior of said Windings. p
A playing-ball comprising inbombination a' bagorcontainer having therein a plurality of liquids of difierent specific Vgravities and which liquids are of such character that they do not mix With each other, windings surrounding said container, and a Wear-res1st1ng casing surrounding said windings. A
i. A playingball comprising in combination a bag or container having therein 1ncompressible llqulds of different specific ,gravities, windingssurrounding said container, and ,a Wear-resisting casing .surrounding said-windings.
5. A playing-ball having in combination a bag or container comprising-a layeroi' rubber and a layer oi material to protect said rubber, a plurality ofhquids one of which is mercury contained in said bag, Windin s of rubber about said bag, and a Wear-res1stwearer.
ing casing constituting the outer portion or" the. ball.
6. A play1ng-ball having a core which comprises a bag having a layer of fabric or other reinforcing material and a layer of rubber, a plurality of incompressible liquids in. said bag of difierent specific gravities, windings about said bag, and a Wear-resist ing casing constituting the outer portion of the ball.-
7. A core for playing-balls comprising in combination a bag or container having therein a plurality of liquids of different specific gravities, said. liquids being or such character that other. i
8; A playing-ball comprising in combination a bag or container having therein a plurality of liquids,-sueh as ater and mercury,
they are not soluble in each rubber windings surroundingsaid bag or 111A playing'ball of the class described oinprising in combination a bag or conf thin-er having therein liquids, such as Water and a liquid having a specific gravity difierent from Water, windings surrounding said bag or container, and a Wear-resisting cas-i ing constituting the outer portion of the ball.
