are! 20; with brace 21 which I will now describe. Connected to the upper end of the vertical link 15, is a member 34, the rear end of which is provided with a longitudinally extending slot 35, the opposite ends of which slot are turned downwardly, as at This slot has a through pin 36, in the upper end of the vertical standard 20, therethrough. In Figs. 3 and 4, this member 34 is reversed, it will be noted so that the ends of the slot 35 are turned upwardly, instead of downwardly, as in Figs. 1 and 2. The reason for this will be described later in this specification. Pivotedto the upper end of said vertical standard 20, is an angle lever 3'7, pivoted at its angle at 38, and provided in its end or toe with a pin 39, positioned to engage under the end of the member 34. The upper end of said angle lever 3'7 has attached thereto a pull cable 40, whereby it can be rocked on its pivot mounting to raise its toe and the pin 39 therein to engage and raise the end of the member 34 to move the slot end 35' over the stop pin 36, and thus prevent endwise movement of said member 34, and also to prevent the rearward movement of the vertical member 15. The weight of the end of the member 34 normally holds the angle lever 37 in its upright position as seen in Figs. 1 and 2. In Figs. 3 and 4, said angle lever 3'7 is pulled to raise the end of the member 34 and thus to release it so it can be moved rearwardly with the slot 35 moving on the pin 36. I

' With the mechanism thus far described, it will be seen that pull on the vertical member 15, may be direct on the frame member 11 without any rearward thrust of the member 23, as in the positions shown in Figs. 1 and 3, or with the thrust movement permitted, as in positions shown in Figs. 2 and 4. The rearward thrust movement of said member 23, operates to move the vertical lever 22 rearwardly, and inasmuch as this is secured to the arch axle A, the action is to raise the frame members 10, as indicated in the light broken lines in Fig. '7.

I will now describe the two kinds of implements which can be secured to the rear ends of the frame members 10, 10, one implement, Figs. 1 and 2, being digger prongs, and the other, Figs. 3 and 4, being a scraper, both implements having stops for cooperation with the stop mechanism on the end of the long member 23.

Referring first to Figures 1 and 2, in which a digging device is shown, there is a series of yoke members or arms, as 40, spaced apart and secured at their top sides to angle members, as 41 and 42, and also 43, extended crosswise from one side to the other of said mechanism, and with plates, as 44 securedthereto, and by means of which said digging device is pivotally mounted in the ends of the two side members 10, 10, for revolving movement. Each of said arms is provided with a digging point or shoe 45, telescoped thereon and secured by means of through bolts 46. The digging points or shoes 45 have beads of extremely hard metal welded longitudinally along the outer surfaces of the digging tooth to offer greater wearing resistance. The plates 44 are formed with rearwardly projecting points, as at 44', to catch in the ground when said device is turned over and to cause it toturn instead of sliding. The pivotal connections at the opposite ends of said digging mechanism, designated 4'7, permits said digging device torotate between the ends of the frame members 10, 10, as will be understood from the showing. The cross members 41, 42 and 43, across the top of said device form stops to be engaged by the dogs or pawls 2'7 and 29, and the operation of which will be described later in this specification.

Referring to Figures 3 and 4, in which a scraper mechanism is shown, the scraper bowl is designated 48, pivotally connected at its opposite ends, as at 49, between the ends of said frame members 10, 10, in the same-manner as said digging device is mounted. These devices .or implements can be interchanged one for the other between the ends of said frame members 10, 10, as may be desired. Said scraper bowl has at its opposite ends, arch members, as 50, with slide shoes 51 around their forward sides, as shown. In the middle of said bowl is an arched member 52, provided with two stops 53 and 54 to be engaged by the dogs or pawls 2'7 and 29 at different times in the operation of said mechanism, as said bowl is turned on its pivotal mountings 49, under the rearwardly extending long member 23. In Figures 3 and 4, which are side elevations, the end arched members only are seen, but in Figure 5, the middle arched member 52 can be seen, and inasmuch as it is in the middle of the bowl, it has no slide shoe. The operation of this device will be described later herein. It will thus be seen that I have provided an earth working mechanism in which there is a body frame or structure, 10, 10, with

carrier wheels

13, 13, and with a coupling mechanism which includes a pivoted member 15, with coupler 18 therefor, and a longitudinal thrust member 23; that there is an earth working implement, 44 in one case, and 48 in another case, interchangeable in said body frame; that there is a supporting connection and holding mechanism on said longitudinal thrust member 23 for controlling the operative and inoperative positions of the earth working implement. I have also provided a spring S, connected with the underside of the frame member 10, and at its other end connected to an arm 14 on the arch axle A, whereby said body frameand said wheels are heldnormally and yieldingly in one position and their relative movements are against the tension of said spring S. The rela tive movement between the longitudinal thrust member 23 and the body frame 10, can be prevented by adjustment of the link or member 34, to interlock it with a pin 36 on the fixed vertical standard 20, where it is desired to prevent such relative movement.

The use and operation of the apparatus may be briefly described as follows:

Referring first to Figures 1 and 2, with the parts in the positions shown in full lines, if power is attached to the coupling means at 18, the digging ltd points 45 will be thrust into and through the earth as said apparatus is pulled over the surface thereof. With the link or member 34 in the position shown, it is free to move back and. forth longitudinally. With the parts in these positions, as said implement moves through the earth there to cause the points of the digger, or the edge of the scraper, to be directed upwardly. The spring S, acting on the arch axle A is yieldingly pulling on the arm 14, as the arch axle, with the frame, moves up slightly and back. Thus when working in earth having a varying degree of compactness or containing rocks and stones in varying density an uneven load or pull when operating at a given depth is exerted upon the draft mechanism causing the implement to move forward with a rocking movement, which decreases and increases the depth of operation as is necessary to maintain an even load or pull on the draft mechanism. In other words, when an obstruction is engaged by the implement so that the strain on the draft mechanism is increased, then the draft member 15 is forced back to the position shown in Fig. 2, and the implement is rocked as also shown in Figure 2, this extra pull also raises the body frame, as will be understood from the diagrammatic view, Fig. '7, causing the digger points to operate at a higher level which offers less resistance, thereby decreasing the strain on the draft mechanism. The length of the longitudinal thrust member 23 can be adjusted by the screw 24, thus making it possible to regulate the rearward pressure exerted on the top of the implement to resist the forward rocking thereof caused by the engaging of the points in the earth. In case it is desired to prevent any rearward movement of the thrust member 23, it is only necessary to pull on from said views.

from its operating position the cable 33 is pulled to withdraw dog 2'7 from engagement with stop 41, thus permitting the forward motion of the apparatus to revolve the implement, thereby withdrawing the digger points, in case of the digger implement, from their operative position, and in case of the scraper implement, revolving the bowl for discharging the accumulated material. To hold the digger implement in the inoperative position for transporting purposes the stop member 43 is permitted to engage dog 27, as illustrated by the dotted lines in Figure 1. The stop 54 on the scraper implement engages with dog 2'? for holding the bowl and blade in the position used for leveling and filling in. In Figures 3 and 4, where the scraper is shown as the implement, the member 34 is reversed, and it is normally interlocked to hold the scraper in the earth, but should it strike an obstruction, by pulling the cable 40, the

\ member 34 can be released, and the movement indicated in Figure 4 will result and the scraper will be raised out of the earth.
