Specification of Letters Patent.

Tatented Mar. id, 19M. Renewed June 30, 1913. Serial No. 776,707.

To all uf/lam 'it muy concern Be it known that l, GEORGE F. PRENDER- ons'r, a citizen ot the Unitel States, residing at Bu;tl"alo, in the county of Erie and Ccitate ot New York, have invented certain new and useful improvements in Spinninglops, of which the following is a specification.

My invention relates to spinning it has for its primary object the provision of a top comprising two spinning members, one or" which ,is retained on or within the other and adapted to be forcibly removed when the top is driven into contact with the ground, the spinning member forcibly removed being propelled a considerable distance in the air and caused to spin so that when it gravitates it will strike the ground with its peg and both spinning members will spin at the same time.

ii further object oit my invention is the provision oit a top having two spinning members, one provided with a movable peg and with a cavity and the other provided with a rigid peg and adapted to tit into the cavity et' the first-mentioned member, said movable pcg being driven into its member to :forcibly project the member having the rigid aeg.

lilith these and other objects in view to be hereinafter described, the invention consists in the novel features ot construction and in the arrangement and combination of parts to be hereinafter described and particularly pointed out in the subjoined claims.

ln the drauf'inga-lligure l is a side elevation ot' a top embodying my invention. ll 2 is a central vertical section of the top. llig. 8 is a cross-section takenon line ii-3, Fig. Q.

Referring new to the drawings in detail .like numerals of reference refer 'to like parts in the several figures.

rllhe reference numeral l designates the top considered as a whole, which comprises two spinning parts or members 2, 3, the spinning member 2 having a cavity 1i in its upper end, :from the lower end of which entends a bore 5 which opens at the apex, as at 6. Said bere is reduced in diameter at its upper end, as at 7, to provide a shoulder S and in lower end is threaded or otherwise securely fastened a sleeve or ierrule 9 having a bore corresponding in diam` eter to that of the top at 7. Arranged slidably within the bore of the top and that of the sleeve or errule 9 is a peg 10 having a tops, and i collar or other projection 11, said collar or projection being adapted for movement within the large portion. oit the bore 5 bctween the inner end of the sleeve or iferrule 9 and the shoulder 8, said shoulder and sleeve acting as stops to limit the movement in opposite directions et said peg. The peg has free sliding movement within the bore of member 2 and the sleeve 9 and is normally extended through the apex et' the top with the collar l() in contact with the ierrule or sleeve 9.

rlhe spinning member 2 is preferably constructed -trom wood and the cavity therein is shaped to receive the spinning member 3 and retain the same in place by irictional contact. The spinning' member 3 is preferably constructed oi Celluloid or other light material and may be hollow, as clearly shown in Fig. 2, the usual methods for .manufacturing hollow Celluloid articles being employed for this purpose. Member 3 has a rigid peg l2 secured thereto in any suit- Iable manner and when said member is placed in position within its receiving cavity, the rigid peg 12 is in direct line with the slidable peg l0. liVhen the spinning member 3 is placed within member 2 it projects slightly above the upper edge oi' the latter so that the top is given an appearance resembling the standard top so generally in use. rl`he operation of spinning the same is like that ot the ordinary top, it being simply necessary to wind the string around member 2 in the usual manner and when propelling the top to the ground, the slidable peg is forced into the top by quick and powerful action caused by its impact with the ground so that the inner end thereof is brought violently against the fixed peg oi' member 3, thus causing the latter to be projected into the air a considerable distance while spinning. ritter the force imparted to member 3 to propel it upwardly has been expended, said member gravitates to the ground, striking the same with its peg and spinning until the whirling force applied to it has been eX- hausted. This top therefore has two spinning members, both of which are caused to spin upon the ground by a single unwinding of the spinning string. If desired, member 3 may be caught upon a paddle or the hand while gravitating and be retained in position on the paddle or hand while spinning.

llVhile I have shown the member 3 con- Cir structed ot' Celluloid or other liOht material I it may, Aiowever, be constructed of wood or other material and need not neceesarily be made hollow, although l have found by experience that if constructed light and made hollow it may be propelled into the air a greater distance than ir" made solid and of heavy material.

Member 2 may be referred to as the main top and member' 3 may be termed an auxiliary top, and while the construction shown and described is now considered the preferred, minor changes in construction may be resorted to without departing from the spirit ot my invention or sacriiicing any ot the aovantages thereof.

Having thus described I claim is,-

l. ln combination in a top, two top members, one carrying the other and having a movable element adapted to project said other upwardly when the top is brought in Contact with the ground.

2. fr spinning top comprising a main top having a movable peg and an auxiliary top carried by said main top and adapted to be driven into the air by the movable peg of said main top.

3. A spinning top comprising a main top having a cavity in its upper end and a slidable peg normally projected and adapted to my invention7 what be moved into the main top when brought in contact with the ground, an auxiliary top held within the cavity of said main top and having its peg in line with the slidable peg of said main top and adapted to be forcibly engaged by said slida-ble peg to cause the auxiliary top to be driven from its cavity while spinning said main top.

t. A spinning top comprising a main top having a Cavity in its upper end and a shouldered bore extending downwardly from said cavity, a errule fitting into said bore from the apex of the top, a peg slidable in said errule and bore and having a collar adapted to engage the shoulder of said bore and the inner end of said errule in its opposite movements, and an auxiliary top held in said cavity by irictional contact and having a ixed peg adapted to be engaged by the inner end of said slidable peg when the top is propelled to the ground so as to project Jdie auxiliary top from its cavity while both pegs are spinning.

In testimony whereof, l have atlixed my signature in the presence of two subscribing witnesses.
