Schneider, Buffalo, N.y Y. Application December 7, c claims. (corti-‘ssii ’ i This invention relates to a to-y railroad and has. as its object the provision of a trackway having a new and novel configuration. , Among the objects of the present invention, are the provision of a trackway for a toy railroad. whose Vcourse is new and novel and' has been found to be practical and pleasing to observe; the provision of a trackway which is continuous and >endless in its extent and is at the same time 10 free from grade crossings, thereby eliminating ' the necessity for switches., frogs, and the like; and the provision of a trackway which fulfills the foregoing objects and has suflicient variety in its tortuous pathway to avoid the usual mo-notony of devices of this class and at the same time pro vides a sim-ple and practicalconstruotion. In the drawing: Fig. 1 is a plan view of my new toy railroad trackway; 20 l SeriaLjNo. 114,527 - Fig. 2 is a side elevation thereof; Fig. 3 is a vertical cross sectional View along the line 3--3 of Fig. 1; and Y' ’ Fig. 4 is a vertical cross sectional View along the line 4_4 of Fig. 1. ' Atthisiznoint ya portion >I,5__ of trackway I3, I4 ex tends obliquely across the bar I0. This oblique track v‘portion merges lat each of its ends into a curvilinear portion I6, which in theinstance il lustrated is.' approldmately an .arc struck from thefcente'r of sealchblock ,I I `and Vextending through approximately 27.0°, whenzboth of the curvilinear portionsmerge into oblique >portions I'i which are ,substantially adjacent each other and ex tend ¿across <the >`:tlrst Amentioned oblique portion 10 ata‘bout-right îangles thereto. During the 4course .of the trackway from the first mentioned «oblique‘portion »to the two latter mentionedand co-'planar oblique portions the trackwafy inclines gradually vupwardly so .that the 15 two second Vnamed oblique: portions are spaced above the ñrst .named 'oblique portion at a dis tancesufllc‘ient .to permita toy electric train to poss'falong the -ñrst mentioned .oblique portion and-¿beneath ‘the two latter mentioned oblique portions. ' The two «oblique portions I’I again mergeinto :curvilinear portions »I8, which in the While various structural designs may be de vised for supporting my new trackway I have i1 instance illustratedapproximate arcs struck from the..~b'locks I I and :continue for about 270°, and merge into a common oblique track portion I9 .which is, in `theplan view, Aapproxirr'iately coin lustrated, for the purposes of exemplification'a cident with :thefñrst namedv oblique track por wooden base comprising a. longitudinalyextend-` ing member I9 having blocks II secured to the 30 opposite ends thereof. n A series of arms I2 ra diate horizontally from each block II and carry at their outer ends vertical supports of vary ing heights and which will later be described. The base members Ill, II and I2 are all adapt 35 ed to rest upon a floor or -similarsupporting sur face. The trackway itself may be of any con ventional type. I have illustrated a` form of trackway which consists of a baseer bedmember I3 which is preferably of wood or other insu 40 lating material and Vcarries thereon rails I4 which are of an electrical conducting material for the purpose of establishing an electrical circuit and supplying energy to a toy electric train of the usual type. In place of the construction 45 shown thetracks may be supported upon a me tallic Vbase structure with a third rail insulated from `the remaining structure and supplying the energizing current. Any desired and conven ient type of toy trains, electrical or otherwise, 50 may be used and the trackway adapted thereto. My new trackway is endless and continuous in extent, that is, it traverses a complete closed cir cuit, but for the purposes of the present descrip tion and for describing the path thereof I shall 55 begin at the >central lowermost portion thereof. tion'` 1.5. » . ' ' Y The curvilinear portions I8 also ascend grad -u‘ally so'that lthe oblique «track portion I9 is 30 spaced `above .the two adjacent intermediate track portions a. distance sufficient to permit a Ítoy’electric ‘train traversing either of the inter mediate adjacent track portions I‘I to pass be neath the upper track portion I9. Vertical sup ports 220 .extend- between »the ¿base .of the track plate :13 and -thefbase structures» Iii and I2 at suitableintervals--for supporting the trackway and the ïheight of theseveral vertical supports 20 is graduated as required. Aj `~It -will ¿be noted that the -curvatures of the lower track portions, »that is, the track portions extending from the lowest level to the interme diate level, are of >generally greater radius than the curvatures ofthe upper track portions, that is, those extending from the intermediate level tothe topmost level. This difference in radius is preferably about the width of the trackway and is provided so that the toy train, when travel ing from. the lower -to `the intermediate level, Will not be interfered with by the upper track portions or by their supports. ¿I prefer that my trackways be banked at curves so that there will be no danger of the toy train leaving the tracks owing to centrifugal 55 2 2,111,944. force. Such banking is illustrated at Fig. 3 which is a cross-sectional View taken at one of the curved portions. For greater structural sta bility I have shown, in my illustrated embodi Ul ment, reinforcing members 2| extending along the opposite sides of the railroad bed I3 in the vicinity of the central obliquely extending track portions I5, l1 and I9. It will be seen that the oblique straightaway 10 portions which are shown in the drawing- and of the other of the adjacent track portions re spectively, and curved track portions connecting the opposite ends of the lower track portion with the ends of the adjacent track portions lying opposite their juncture with the first mentioned tirely and the circular portions may be substan curved track portions to provide a continuous and endless trackway. 3. In a toy railroad, a trackway comprising two adjacent stretches of track, a track portion passing above and another track portion passing beneath said adjacent stretches of track, curved track portions connecting the opposite ends of tially complete so that they merge directly into each other, or the straightaway portions may the adjacent track portions and the opposite which have been described may be omitted en the upper track portion with one end of one of all extend in the same direction, that is, at’right end of the other of the adjacent track portions angles to the member I0 as viewed yin Fig. .1. respectively, and curved track portions connect The curvilinear portions have been shown as ing the opposite ends of the lower track portion arcuate but it will be understood that these por ` with the ends of the adjacent track portions lying tions of the track may be of any suitable shape opposite their juncture with the first mentioned curved track portions to provide a continuous 20 or configuration only so that they interconnect with the straightaway portions or with each other and endless trackway, said second mentioned curved track portions lying substantially outside in the manner and at the levels described. In operation the toy train beginning at the said ñrst mentioned curved track portions. h4. In a toy railroad, a trackway comprising lowermost portion I5 >oiy the trackwayvexecutes a figure 8. Midway in the'execution of this figure 8 the train will be found at the inter mediate level of track and upon `completion of the iigure 8 at the topmost level. ‘The train continues from this point to execute a second 30 ñgure 8, passing the intermediate level midway and again arriving at the lowermost level upon the completion of the second figure 8.: It has been found in practice that the toy rail way herein shown and described results in a. train 35 route which is pleasing to the eye and quite in triguing in that the path of the train does not readily photograph itself upon the -mind of the observer. The exact modusoperandi is not so clear from actual observation as pictorial delinea 40 tion and verbal description may make it appear. The path of movement of the train is graceful and to a large extent avoids 'the monotony in cident to observation of the operation of a toy railroad train in a single level.. The smoothness 45 and grace of operation is further enhanced by the complete absence vof switches ¿or frogs and this latter feature results. further. in more quiet operation than is usually the case in devices of this 50 class. - » 1» . » " the upper track portion with one end of one of the adjacent track portions and the opposite end of the other of the adjacent track portions re spectively, and arcuate track portions connect ing the opposite ends yof the lower track portion with the ends of the adjacent track portions lying opposite their juncture with the ñrst men 35 tioned curved track portions. 5.
