This invention relates to wheeledr vehicles such as push carts, barrows and the'like and has for one of .its objects to improve generally upon this .type of vehicle,

Another object is to produce a device of this f kind having a relatively low wheel base with the bottomof the body or the platform part of the device and the handle members arranged in a definite Vcorrelated angularity with respect to each otherand in -a general plane in proximity to the periphery of the'groundfwheel or cylindrical supporting roller solas to aiford easy handling of the device as well as a convenient'placement of the handle members so that the device may be pushed or pulled with minimum physical effort on the part' of' the operator. 1'

Other objects and :advantages to be attained will hereinaftermore fully-appear in the 'following description'.l .l l i l 1- An illustrativebut@non-limiting'practical exemplication of the inventionv is illustrated in the accompanying drawing, in which:

s Figurel is a, top'planvviewy f Figure 2 is'a side elevational'view;

Figure Sis a forward` end View;

Figure 4 is aiear vend view; and

Figure 5 is a longitudinal section on the line 5`5 'ahdon asome'what enlarged scale. Y

Referring now to the drawing in detail, the

numeral 6 designates, generally, the main bodyV portion of the device which, as shown, is of the plain platform type. However, as far as the present invention is concerned, the body may include side and end walls (not shown) which may be either xedly secured to the platform or bottom portion 6 or provided and arranged so as to be detachable therefrom.

Instead of the usual narrow rimmed wheels a cylindrical hollow roller 'I is provided. This roller may be made of any suitable material, but as shown it is made of wood. The same may be constructed in any suitable or appro-ved manner. As shown, it comprises circular end heads 8 built up of strips or segments placed edgewise together and, preferably, each in double thickness with the strips or segments of the one layer disposed crosswise with relation to the other layer. So, too, the heads 8 maybe constructed in any other laminated or in a single piece form. The peripheral portion of the roller 1 may be built up of elongated rectangular strips or staves 9 and nailed or otherwise fastened at their ends to the heads 8 by nails or other suitable securing means.

The body or platform portion 6 is provided at its opposite longitudinal sides with cleats III on acxaims. (c1. 2804-58) 7 y theunder sidethereof. Y

.of beingl directly vertical.l

Secured on the inner sides of `the forward endlportions' of 'said cleats I0 are angular 'struts II which incline inwardly .and downwardly from said end `'portions of the vcleats -I'I.` These struts II are of a length so that vtheir lower ends terminate so as to be securedto 4the upper side'of the forward endportions of elongated frame members I2 which are extendedbeyond' the rear end of the body or platform. 6 to constitute handle members I3, the free end portions of said handle members I3'being reduced in size 'and shape to' provide convenient hand grips I4. i" g The innerend portions of thev cleats IIIofthe' body or' platform portionliga extended some distance so as'to bey securedonthe outside of the adjacentvintermediate portions ofv said integral frame side members I2 and handle extensions I3, as at I5 (see Figure 2)', Extending downwardly from the side frame members I2 at transversely opposite places where the platform 6 terminates at its innerend andthe handle extensions I3 continue therefrom is a pair of supporting legs I6. These `:legs I 6 extend'perpendicularly from the membersIZ so that when theleg members are supported withtheir lower' ends on the ground theywarefdisposed at a slight inclination instead Diagonal side brace members I 'I are attached at their forward ends to, the corner portion of the side framing adjacent the forward end of the platform 6, as at I8,"and their lower inner end portions are attached to the lower end portions of said leg members I6, Y

as at I9, the intermediate portion of the members II crossing the membersI I2 and being secured thereto, as at 20.

The forward strut members II are cross-connected by a transverse brace member 2I which is fastened at its ends to the outer face portions of said members II and it extends parallel adjacent .to the forward edge portion of the platform 6. The lower end portions of the supporting legs I6 are cross-connected by a transverse brace 22 and said legs I6 are also cross-connected by a diagonal brace 23 which is attached, as at 24,

to the lower end portionof the left legV I6 and closely contiguous to the adjacent end of the cross brace 22 and its opposite upper end portion is attached to the right leg I6, as at 25, closely adjacent the under side of the companion side frame member I2.

The cylindrical groundroller 1 may be mounted on the side frames of the device in any suitable or approved manner. As shown, the roller 'I is provided with a shaft 26 which extends axi- Y respecttoithefaxissoitiresupporting;rollercfl.A

That is to A say, the shaft and the roller rotate the one by and with the other and also they are fixed to move endwise. together,v The extreme end por- Y tions of5-theshaft 26" arev journaled a'conveny- 10 tional manner' in' bearing elements 21 secured' on the under side of the forward end portions `of said side frame members l2.
