3 Claims. (Cl. 37-133) The present invention relates to new and useful improvements in earth working apparatus.

An object of the invention is to provide an earth working apparatus of generally improved design.

Another object of the invention is the provision of an earth working apparatus which is vhighly eiicient for scraping, earth carrying and load dumping.

A further object of the invention is to provide an apparatus of the above character having nuid actuated means for operating a scraping, carrying and dumping member thereof.

Still another object of the invention is to provide apparatus of the aforesaid character which is compact, durable and relatively simple in In describing my invention in detail, reference will be had to the accompanying drawings illustrating a practical adaptation-of the invention, and in which:

Figure 1 is a top plan view of the apparatus in earth carrying arrangement,

Figure 2 is a view partly in side elevation an partly in' section of the same,

Figure 3 is a longitudinal section taken on line 3-3 of Figure 1 with one section of the bowl in earth dumping position,

Figure 4 is a similar view showing the bowl of the apparatus in earth scraping position,

Figure 5 is a fragmentary longitudinal sectional view showing the digging elements in extended digging position,

F'Eure 6 is an end elevational View of one of the bowl sections,

Figure '7 is a transverse sectional view through the complementary bowl section,

Figure 8 is a transverse section taken on line 8--8 of Figure 1, and

Figure 9 is a top plan view of the frame of the apparatus.

With reference to the drawings,V wherein like characters of reference denote corresponding parts throughout the several views F generally designates the frame ofthe apparatus which embodies a rectangular shaped body section having an elongated draft bar l5 extending forwardly from the center of the front transverse frame bar I6. 'I'he rear transverse frame bar I1 is advantageously of channel shaped cross section formed with a pair of spaced forwardly directed bearing eyes I8. At the medial portion of each side bar I9 of the frame body is provided a bearing 20. A pair of converging bars 2| serve to reinforce the connection of the draft bar I5 with the body section of the frame. To the forward end ofthe draft bar is connected a hitch head 22 provided'with a plurality of apertures for adjustable connection with a tractor T or other suitable draft means.

In each of the side bearings 20 is rotatably mounted the inner transversely directed journal portion of an axle crank 23 having-the right angularly directed arm disposed outwardly of the framey and having each of a pair of supporting or carrier wheels 24 rotatably mounted on the outwardly directed spindles thereof. The. journals of these cranks are disposed in transversely aligned position and vare formed, at their inner ends, with anges forming transversely disposed disks 25 which serve to support a bowl section 26.

This bowl section embodies apair of approximately semi-circulan end walls 21' formed integral with or connected to the end edges of an essentially arcuate bottom wall 28 extending transversely of the frame between the end walls, and from the front of the section to a point slightly exceeding one-half the extent of the outer edge of each of the end walls. Secured to and extending between the rear portions of the end walls'21 is a longitudinal bar 29 formed at each end with a web terminating in an upwardly projecting apertured ear 30.' As shown to advantage at Figures 4 and 6, the forward marginal portion of the curved wall 28 may be practically straight to form a scraping portion which terminates in a bevelled scraping edge 3| projecting beyond the ends of the end walls.

Mounted to assume complementary relationship with the main bowl section 26 is an auxiliary bowl section 32 of reduced segmental size having approximately sector shaped end walls 33 whose outer peripheral edges are formed integral with or secured to the end of a bottom wall 3l extending transversely of l the frame and of arcuate transverse curvature corresponding to that of the outer edges of the end walls. In the redu ed ends the end walls 33 are provided with concentrically arranged apertures 35. To the outer side of each end wall 33 is secured an angle member 3 6 providing laterally directed stop lips position within the wall 34. The apertures 35 are fitted on sleeves 31 rotatably mounted on the crank journals between the disks 25 and the frame bearings so thatthe auxiliary bowl section is freely rotatable about the shaft portion of the cranks.

On the forward cross bar I6 are fastened a pair of aligned complementary bearing sleeves 38 having journalled therein a transversely extending rock shaft 39 formed with right angular crank arms 40 at the ends and a crank arm 4I at its center. The outer end of each crank arm 40 is pivotally connected to the inner end of a longitudinally extending connectingv rod 42 bent to form an offset at its medial portion and having its rear end pivotally connected to the ear 30 of the bowl section 31.

To the forward portion of the draft bar i is pivotally connected an elongated fluid containing cylinder 43 having ports 44 and 45 at its end portion and having a reciprocating cylinder 46 operatively mounted therein. To this piston is connected the inner end of a piston rod 41 slidable through a packed opening in -the front of the cylinder and having its outwardly extending end pivotally connected with the outer end of the crank arm 4| of the rock shaft. The ports 44 and 45 of the cylinder are connected with a control valve 48 through the medium of a pair of nexibleconduits 49 and 50. The valve 48 may advantageously embody a rotary plug having passages adjustable to connect the connecting lines 49 and 50 with either the feed port or the discharge port of the valve or, to intermediate positions to cut off the fluid supply. As illustrated at Figures 2, 3 and 4 the control valve 48 may be mounted upon a bracket 5l of the tractor in a position conveniently operable from the drivers seat.

At the rear of the frame F, immediately forward of the channel bar I1 are mounted a pair of parallel rods 52 extended through the apertured projections I8 and apertures in the sides of the frame to support thereon a plurality of, in the present example three, digging implements or picks 53. These implements embody iiat elongated bars having forwardly curved and pointed bottom ends and provided with apertures for adjustable connection with the support rods 62.

To the frame bar I6 is connected, by a hinge connection 54, an elongated scraper blade 55 extending transversely below the frame and preferably shaped to provide an arcuate transverse curvature. To this blade are connected a pair of arcuate arms 56 adapted for pivoted connection with the side bars I9 of the frame at two longitudinally spaced points for firmly bracing the scraper blade in its depending scraping position and to allow movement thereof to a forwardly directed elevated in-operative position. In the latter arrangement of the blade 55 it is releasably supported by a finger 51 slidably mounted on the draft bar by a slide yoke 58.

To swing the bowl of the apparatus from its an earth scraping position as illustrated at Figure 4, the valve 48 is actuated to connect the fluid conduit 49 with thel feed line from a source of iiuid pressure on the tractor so as to slide the `piston 46 toward the front end of its cylinder.

This movement of the piston retracts the, piston rod 41 and, through the medium of the rock shaft and the connecting rods 42, effects clockwise rotation or swinging movement of the closed bowl sections to dispose the scraping edge 3| thereof in a downward position. As the bowl is thus turned the cranks 23 are also rotated to elevate the carrier wheels 24 with relation to the frame and the bowl so that the forward edge portion of the latter is disposed below the lowest' counter clockwise movement while such further Y rotation of the auxiliary segmental'bowl section load carrying position, as shown at Figure 2, to

32 is restrained by the projecting lips 36 which contact with the side bars of the frame. This action separates or opens the bowl sections to provide a substantial gap or opening between lthe adjacent edges thereof for discharging or and dumping and having operative mechanism which can be easily and conveniently controlled from a tractor.

It is to be understood that the invention is not confined to the specific construction, arrangement o'r use illustrated and described and that considerable modification may be made therein within the spirit of the invention as defined by the appended claims. l

Having thus described the invention, I claim:

l. In apparatus of the character described, a frame, a pair of complementary cranks journalled on opposed sides of the frame, a pair of carrier wheels rotatably mounted on the spindles of the cranks, a main segmental bowl section mounted transversely of the frame and secured to the inner journals of the cranks, an auxiliary segmental bowl section pivotally connected with the crank separate the sections for dumping the load therefrom.
