DUMP WAGON.

Application filed January 6, 192-2, Serial No. 527,413. Renewed April 19, 1923.

To all whom it may concern:

Be it knownthat I, Josnrn GAssnn, a citi zen of the United States, residing at Trenton, in the county of Mercer and State of New Jersey, have invented new and useful Improvements in Dump Wagons, of which the following is a specification.

This invention relates to dump wagons and more particularly to that type or form of such wagons which is motor driven, means being actuable by the motor thereof to effect the tipping of the dump-box or body to discharge the contents whilst said dump-box or body can be promptly returned thereby to its normal position.

The primary object of this invention is to provide a novel mechanism for promptly raising and inclining the dump-box or body portion of a dump wagon from its normal position on the chassis or underframe, and vice versa.

Other objects of this invention are the provision of a simple, strong and very effective means for inclining a dump-wagon body portion of box relative to its supporting frame or chassis, saidmeans being operable by the wagon motor. 1

With the foregoing and other objects in view this invention consists essentially in the novel features of construction, combinations and arrangements of parts hereinafter fully described and more specifically defined by the appended claims.

In the further disclosure of the invention reference is to be had to the accompanying sheets of explanatory drawings constituting a part of this specification, and in which like characters of reference designate the same or corresponding parts in all the views. p Figure 1 is a side elevation showing the application of my invention to a motor driven dump-wagon, the dump-box or body portion being shown in itsinclined or dump- 7 thereof, all of saidparts being in accordance with the well known structures of such vehicles and forming no part of this invention.

According to my invention the dumpbox or body 7 is supported on rigidly connected longitudinal and opposed channels 8, 8 adapted to normally seat on the underframe 9 that is appropriately mounted on the chassis 41. In ,order to provide asuitable hinge connection between the dump-box or body 7 and the chassis l secure to said chassis a at its rear end a pair of brackets 10 in which is journaled a transverse shaft 11 the free ends whereof are suitably fixed to the aforesaid opposed channels 8, 8 and it will be easily seen from Figure 1 that said manner of connecting the dump-box or body 7 to the underframe 9 provides a very strong and serviceable means whereby any lateral displacement of the former relative to the latter is effectively prevented.

Appropriately journaled transversely beneath the dump-box or body 7 between the longitudinal channels 8. 8 is second shaft 12 to which are connected the upper ends of arcuate rack bars 13, 13 that serve as later' on explained to raise and incline said dumpbox or body 7 These arcuate rack bars 13, 13 are adapted to mesh with correspondingly toothed pinions 1 1, 14: having side flanges 15, of larger diameter secured thereto so that said arcuate racks 13, 13 are protected against lateral displacement and tor-- sional derangement. The aforesaid toothed pinions 14, lf are keyed or otherwise securely mounted on a transverse shaft 16 journaled in a duplex forked bearing 17 mounted in and securely attached to the 95 chassis 4:. On an examination of Figure 2 more particularly it will be seen that the duplex forked bearing journal portions 18 are upwardly extended to provide additional journals 19 for stub axles 20' having 100 anti-friction flanged rollers 21 adapted to engage that edge opposed to the toothed by those acquainted with the art, to which my invention appertains.

In. the form of my invention shown by Figure 1 it will be seen that the shaft 16 is provided With a Worm-Wheel 23 enclosed in an appropriate housing 24, and said Worm- Wheel 23 is rotated by a Worm 25 on a longitudinal shaft 26 driven through" suitable clutch gearing from the motor transmission are control lever 28 being provided in the drivers cab 29 for engaging; and disengaging said clutch gearing, as will be, clearly, un der stood by those conversant With motorpro- "pelled vehicles. An apropriateknock-out 15 not Sll0Wl1--dCtut1l)l6 by a rod 30 is provided for tripping the aforesaid clutch rearing When'the dump body or box '7 reaches its maximum elevation and lockingsaid dump body in such position. v

In the, modified form of the invention 7 shown by Figures Qand 3 it Will be seenthat' the shaft 16 is suitably journaled 'in an appropriate housing 24J'inounted on the aforesaid duplex-forked bearing17 and that it is provided with a pair of spacedspur gears 31 in mesh with correspondingly toothed pinionsSZ on a coun'ters'haft 38 that is fitted \viththe Worm-wheel 23 driven by the Worm 25 as hereinbefore described.

Which'is particularly serviceable for use in connection With the heavier service types of motor driven dump-Wagons. i

Appropriately supported on the housings -24'by a pivot pin 86 or other suitable advancng means are channel-shaped arcuate members or guides 85' of cross-section correspondstood from an examination of the drawings.

These members or guides areresiliently suspended at their other free end from loosely depending contractile springs 34: which are carried from the chassis by means I of suitable brackets fixed thereto.

These guide members 35 direct the course of the racl: bars 13 as the body descends. and encase thejguides protecting them from dust or dirt While the spring suspension of the free end of the guide absorbs. the shock con- I I From. the

clining means Will be clearly apparent Without further explanation, and v'vhilstthe same has been primarily devised for application to vehicles such as one usually finds devoted to the carryingof material subsequently to be dumped'or' quickly unloaded, I Wish it understood that I do not so restrict myself;

Still 'further it will'b'e obvious that detail changes may be efiected and other combina- Thus it' will vbe seen'that a reducing gear is provided foregoing description and an examination of the drawings, the" operation; and advantages of my novel dump-box ntions of parts evolved that will function in precisely the same manner as the embodiments of my invention hereinbefore out oted beneath and intermediate the ends of said hinged body, an arcuate guide supported from the vehicle, a gear housing member,
