- l '.roYy DUMPING WAGONQ Application yfiled January, 179273. `Serial No.,6`11,053. i I i This invention relates to improvements` in toy'dumping wagons, proposing a construc-y tion which includesan endwise-tiltable'load carrying element or bodyk and 'operating ,5 ymechanism therefor, thebody `having a normal horizontal position and alongijtudinally inclined dumping or .discharging ,posi-A tion l.and the operating mechanism being available to movcthe ybody into either of lorsaid positions. l'

'The inventlon'particularly relateswto theI construction :ofthe body operating mech,- anism and tothe relation of the parts of such mechanisml to none another, to the body aii'dto other parts of the wagon, the inven-y tion'y consisting in novel features ofestructure and arrangement which' Awill be pointed out as the descriptionproceeds and which serve the'objects of strength and-sturdiness, enablingl the wagon to withstand rough. or careless usage, of ease, quickness and positiveness of operation, of the certain' and secure retention ofthe wagon body in either of its operativev positions and of avoiding 5 any interference with the movement of the wagon upon its supporting wheels.

A toy wagon in which the features of the invention are incorporated is shown in the accompanying drawings, wherein: y

3 Figure 1 is a side elevation, a rear wheel being removed. l

Figure 2 is a bottom plan view. Figurek 3 is alongitudinal sectional view, the body being in dumping position.

Figure 4 is a section on the line 4;-4 of Figure; i*

. Figure is a perspective view of the wagon frame. 4 i

The load carrying element l may be of,

yany suitable form but as shown and pref ferred is in the form of a body having iioor. and vertical or approximately'vertical walls. The body land theoperating parts to be later described are mounted ony a frame 2 which includes side bars 3 and cross bars or axles 4, the side bars being preferably extendedat each end for a suitable distance beyond the cross bars..v The wagon is suitably supported, as by wheels 5, although other supports such as runners could be employed. As shown Athe wheels I, 5 are secured by screws l6 which' extendy through lcentral openingsin saidwheels and ends .of the bars y' bars 3.

"the reverse directions.

are engaged inthreaded krecesses 7 atlhc y The wagoni'nay, -of course, be'madejto simulate vanystandard industrial vehicle and is *showny inthe form ofl a motor 'truck wherein ajblock 8v is fashioned to-representy thefhood which encloses theengine and is mounted on a floor plate 9 and securedby screws 10 -to the `front bar` 4. 'lfhe 'plate also carries thev drivers seat 11andvestibulevr i 12, the body 1 "beingllocated behindsuch vestibule. y

The body 1 isflpro'vided on its under side Y with transversefcleats 13 and lll and is `piv-` oted vat or nearitsrear endy tothe rear ends ofthe bars 3, as at`15, thepivot pins (preferably in, the I formof screws) being tted axially iii-"the,` ends of the cleat 13 and engaged in bearings 16 provided on ythe The operating-` 4mechanism is actuated by a crank y17, located at one side of the body land having a rock-shaft extension 18 which is journalled; in a bearing 19 'projecting laterally inward from one 0f the side bars 3. The mechanism includes a two-armed lever 2O which is iiXedly mounted at a point be tween its vends upon Athe rock-shaft 18. A link 21 serves as a connection between the lever 20 and the wagon body, said link bel the cleat 14.' Theleve'r 20 has a normal rearward and downward inclination and thelink 2l a normal forward and upward vinclination from which it follows that the crank" 17is moved clockwise ink order to e shift the body 1 to dumping position,'the upwardmovement ofthe portion of the lever 20 behind vthe shaft y18 being transmitted by the link 21to the front portion ofthe body 1 which is thus moved about its `f pivot 15 to the rearwardly and downwardly inclined position shownin Figure 3.( To restore the body 1 toits normal horizontal position the crank 17 is moved counterclockwise, the connected kparts moving in The relation `of the, parts is preferably such thatwhenfthe `body lis indumping position the rock shaft 18 and they pivots lOO of the link 2l are along dead centers, or substantially so, as shown in Figure 3, whereby the lever 2O and linlr 21 furnish stable and unyielding` support for the Wagon body; and in order to prevent continued movement of the body l beyond such position, the lever 2O is or'ined at its re'a'r end with a stop lug- 22 which comes into engagement ivitli the under edge of tli'e linl; 2l.

The manipulation of the crank 18 may be aided by the employment oi a tension' spring' 23 for the use of which the leverQO is made tivo-armed as above dssrib'e'd. Tlie spring 23 is connected to the front end oi. the lever 20' and to a fixed part of the Wagon', preferably the rear cross bar 4 and is arranged to extend above the axis of the s'lia-ft 1S and tli'e pivotal connection of the lever 2O and link 2l ivlien' the Wagon body is in normal position and to eitend lieloiv said axis and pivotal connectionivlien tlie Wagon body isI in dumpingposition, `these relations being` sho'ivn in Figures l and 3 respectively. It will be apparent 'that the spring 23 completes the final stage of the movement of the parts in either direction and in either position of the Wagon body and holds' tlie same' and the co'nne'fte'd parts against loose play or accidental displacement.

Having fully described my invention, I claim:

A dump Wagon comprising a frame hav ing tWO longitudinal side' bars, liront and rear cross bars connecting,- tbe iront and rear parts of said side bars, pivot lugs projecting upwardly from the rear ends oi' said side bars, an intermediate bearingl projecting` transversely inward from one oi' said side bars between the front and rear cross ba'rs and terminating midway between said side bars, said side bars, cross bars, pivot lugs and bearing' being 'fornei'l integrally, a vertically swinging box provided on 'the rear part 0i its under-side Witli a depending block Wliicli is iu'jranged betiveen said pivot lugs andp'ivotally c oi'ine'c'ted tliereii'i'tli, a roel;- shaft jonrn'aled iii ,saidl beziring'niid provided at itsx outer end Witli a cra'nl', :i lever connected viitli the innor end of said sliaft and liaving 'front and rear oirnrs and a stop `lu0` on saidirear arm.A alink ,connecting tlil lrear arm of said lever and the iront part of said bei; Iand adapted to enf l'oiveripxart said lug, and spring connecting' tli'e'vfr'ont `arm` of said lever Witli said rear cross bar and adapted to yiel'din'gly li'old said bo'( in its livrd or elevated positions.
