Vtionship by a thin wooden pin i.

V constructed in a very simple manner.

A Itoy monorail gure 44 may be placed on top of the track 6 to roll down the trackway and make a loop the loop turn at the bottom of the trackway. The toy gure consists of two ilat boards 50-50 secured together in spaced parallel rela- A pair of grooved pulleys or wheels 52-52 are journalled between the boards 50, the groovesinthe wheels being of width just right to enable those'wheels to embrace and ride on the trackway previously described. Four wheels 54 are rotatably mounted on the outside of the boards 5U. The boards 59 may be decorated or shaped to simulate a toy figure. The center of gravity of theentire figure is appreciably -below the bottoms of the wheels` The toy iigure 49 has been illustrated in Figure 1 in a position on top of the trackway', with'th'e boards 50-50 thereof straddling but spaced fromY the trackway, and the monorail wheels 52-52 restingionvthe tra'ckwayjy AIf the figure is started rolling'down the inclineit will pass from thefportionl 8 of the incline tothe loop formed by the annulus25,traveling through the inside ofthe loopdue" tojthe momentum gained in' traveling downthe'trajckway 6, and then will travel along 1 thef'track formedby the edge of the board 3T.

TheV forward edge of theboard 31 is tapered, as indicated atl'l; so that the forward moving toyV is'"gradually brought closer to the ground until the 'wheels 54'thereof contact the ground, where-` uponfthe toy continues its advance on the ground due toits momentum;V Y l i'InFi-guresand 6 I have' shown a modied construction wherein the track 8 of Figure 1 is made/bf two separable parts, to faoiiitate packing offtl'ie unit for shipment. In/this construction theti'ackcomprises' separableflengths 8a and 8b ofplywoodlying in the sameplane and joined at""th`e"'support 18a. The bottom of the board 8a rests on thetop of the'board 8b and has' a inclinedtongue-GU `which enters into a corre-` spondingly'shapedslot 6I at the top of thel board 8b'. Thef support |8a` comprises two similarA fiat sided'jlboards [i5-.66 which are parallel toone IY Vaffecter:Thebottoms of the. Iboards lss-sant rectangulai"islots`V in the base- I4 and are securedthereiri in spaced relationship'. The dis'-v taicefbetween theboards 65-66 is equalto the thickness of theindividual boards 8a orSb." A

indicatedat 69, and embrace and hold the bot-` tmofthejtrack portion 8a against Jtransverse movement. The top of the track portion 8b and thelbottom'of the track portion 8a are vof the s amel construction as that of th'e corresponding Vportions of the track 8 previouslyV described.

The ltrack portion 8a maybe removed by a simple upward or lifting action.

' Fromtheabove description it is apparent that Y I have provided a simpleloop the loop type of;

monorail toy wherein the trackway constituting tlieincline is made in a simple manner and wherein the loop portion of thertrackway is also In 'compliance with the requirements of the patent statutes I have here shown and described a preferred' embodiment of myinvention. It is;

however, `to be understood that the invention is not `Qlimit'ed tor the precise construction here shown,V the Vsame vbeing merely illustrative of the `principles. of the invention. AWhat I consider i new and desire to secure lby Letters Patent is:

1. A trackway Afor a loop the loop monorail toy vehicle, said trackway comprising a thin board mounted in a vertical plane with an edge of the board inclined and constituting a portion of the trackway, a loop at the bottom of said portion of the trackway, said loop comprising a thin board of annular shapeslit by a line of cut extending `from `the innerecircleof Ythe Yannulus toits outer peripheryrthecut'. edges` being sep- 'Y arated from one another to form Ythe loop into aspiral of an arcuate extent substantially 360,

the loop being positioned with its axis at right angles tothe plane of the said rst mentioned board and with the inclined trackway tangent to the inner curve of the annulus,` said inner Vcurve of the annulus constituting another portion of the trackway and a continuation of said iirst V mentioned portion of the trackway.
