This invention relates tol new and useful improvements in toys andthe primary obj ect is to provide a toydesigned in the form of a tractor which Iis adapted tov be drawn'along the ground by achildthrough the medium of a flexible connection. l 'i A further object of the i vention resides in providing a device of the character mentioned in which opposed guide membersarev provided between which operates loosely disposed Iground engagingelements, the latter pushing; one another forwardly as Athe device is drawn along the ground.

l Still another ob] ect of theinventionresides stantiallyfoval `shaped guide, members or tracks upon and between which the loosely disposed ground engaging members are supported, so "that as thedevice is propelled, l

`these ground engaging elementswill travel continuously around the opposed members,

themselves forcing" one another forwardly into ground engaging position. f

` Still another object resides in providing a `device which will beextremely novelin appearance,vinteresting-to children as well `as n silnple'rland durablein constructioni l With'theseandnumerous other objects in view my invention` consists in the novel features of construction, combination and` arrangementofparts aswill be hereinafter ,l referred to wandmore particularly `pointed out in the :specification andclaims.

i fIn :describing` the invention I shall refer therdrawngs in which similar-reference @hamsters designate mrrespondng -perts said" `blocks slidefloosely` sand `readily over these members 1 :and 2. :As many of the blocks maybe providedas desired to ll the ,drop `downwardly by gravity; over the curved n the device is propelled forwardly. Y

throughout the several views and in which 1 and 2 designate substantially oval-shaped track members which are positioned in `opposed relation and held in spaced yrelation one tothe other,;through the medium of brac'-

ing elements

5 and 6. These track members are formed preferably of metalland aref'substantially channelshaped incross sectionyas clearly shown'in `Figure 2;"of thedrawings.

The purpose of this will `be" hereinafterand ce more particularly set forth.;` l Supported `on `certain i of the transverse bracing elements 5 1s a member 7 representing.;l

a pilot `house or cock-pit inwhich isdisposed afigure represented by the numeral.` Any i form offgureor member may be placed in y U ,thisposition as a substitute if desired,as this forms no essential feature of the invention. 'pI-he tractor feature Vofthis `device is supplied by the medium ofa plurality of blocks 9, in the ends of which are provided grooves A1V()\for reception therein of the outer-most horizontal flange of the channel-shaped members :1 and `2, asclearlygrshown in Figures 2 Y and 4 of the drawings. Theseblocks 9 are swung. into place between the track members `1 and 2 so that the grooveslO receive the up# per-most flanges of these members g1 and 2 and entire-space, ifV desired, but preferably a less ,number is provided: than would be `necessary to thev entire rack so thatthe blocks may Y `18.5 forward portion of themembers 1 and 2 as `A bail memb ern/12 engaged the meme `bers 1 and 2.at `theforward endfthereof to" `whichfis connectedwa: flexibler connection 13 ground by a child playing therewith. As the device is drawn forwardly the elements 9 contacting with the surface of the ground will be forced rearwardly one against the other and said members are forced over the tracks l and 2, travelling continuously thereover. f As the--blockmembers 9 yon "the upper stretchlof 'the track members land` 2 'reach the forward curvature of said members they willv dro downwardly V by gravity into A,position to ge ground. In this manner a tractor is `provided Wherein the tractor elements aredthemselves disconnected and force one another over the tracks and into ground engaging position. y e

InfFigui-es I5 and 6 as shown "a slightly modified 'form of groundV engagingfelements. Each such element, designated yby the inumeral 14 is made from `a"singlestrip of meta-l "berit'and looped :to yform a lmIlOwineInber. One faceof the member'is corrugated as shownatfl, the corrugations extending llongitudinally of the member to VVform friction means for engaging the Vsur-face of Ythe ground. The end'eiges 'oftheinember 14.- are rd as shownn at l''toreceivethe'i-ein the upper horizontal ianges of vthe track rinein- 'bers 17and"2. Thisifs'one modification of down-engaging elements and it 'will' be y understoodV that various other En'iodiiications lmay rbeuti'liz'edf. In the preferred form of the vinvention using the blocks 9 vthe weight of the blocks tend to'retain'the device against 'the surface of'ltlie ground. AWhen 'usingthe modification as shown in 'Figures 5 and 6, should the devic'ebe too light, a'weiyght'inember -niaybeprovided'in connection Awith the ligure or hou'singheld' between 'the vopposed track members.` g Y This toy, as stated herenbove, isusefi'il 'fior instruction' 7purposes land *to lcarry out this idea, the upper faces ofthe blocks `9 arep'ief- `erabl s" respectively 'provided with 'letters of the alphabet, Which'may 'bei painted or otherwise Vinscribedthereon. A As fthe device is these letters may 1 be viewed-'from the top "ofthe device and afs the blocksmove 'forwardly on the i device "the various ,letters may'be 'studied f a' chil,I playing with' the toy. The use of'lettersfia"ofcourse, illustrated of omem'ans f'applying instruction educational elements to this device and I do notwishfto'be limited strictly/to ythe use ofthe letters ofthe' alphabet asfit is apparent timttvari'ilsfotherilustrations may be' used rt'o actbmpxlisn'the same purpose.v l Y t e lioregoingdesei'jiption of thefc'onof ni'yimproved device,`fthe1opra itwill seen nthat I have rovidedafsimple, nexnsite randIetic'ieniiti j eaiisffer carrying 'dut y objects thefinvention. L y 1 Y While #I Ahave alitieulariy descbeii 'fthe dem man wdofpefforni the ffuneengaged with Ithe "surface o1 the tions set forth, it is obvious that various changes in form, proportion and in the minor details of construct-ion may be restorted to, without departing from the spirit or sacrificing any of the principles of the invention.
