Application filed August 26; 1925. Serial No. 52,609.

To all whom itmag 0092mm:

Be it. known that 1, JOHN FaSNninmia citizen of the United States of America, and resident of Weston, in the county of UmawThis invention relates to weeders, and

particularly to a' type of .weeder having blades which are operative over af relatively wide area as-the weeder is drawn over the soil tobe weeded, and it is an object of this invention to produce a-weederin which the blades may beelevated to cause them to clear obstructions or to rid 'themselvesof accumlation's of weeds or deposits which sometimes foul the bladts devices of this type.

It is a further object of this invention to provide a novel mounting and. draft rigging for the "blades and to produce means tby 'which the blades maybe manipulated for raising them clear of the soil being treated when foul deposits are to be displaced.

-. It is a' still further object of this invention to produce a weeder which theoperator may manipulate while riding on the-equipment.

It is furthermore an. object of this inven tion to produce a device of the character indicated which can. be moved without employing undue force, since the blade carrying mechanism is to an extent counterbalanced.

With the foregoing and other objects in View, the invention consists in the details of construction, and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, reference will be had to the accompanying drawings forming part of this application wherein like characters denote corresponding parts in the several views, and in which .Figure 1 illustrates a view in elevation of a fragment of a device embodying theinvention' Figure 2 illustrates a plan view of the said device with parts omitted;

Figure 3 illustrates an enlarged detail view of the blade manipulating shaft and arm; and

Figure 4: illustrates a view in elevation of a device embodying the invention slightly modified as to relation and positioning of the parts.

In these drawings 5 may be, regarded if as an axle having traction wheels such as 6, one of which will beat eachend of the said axle, and the equipment for assembling the traction wheels in operative relation tothe axle may be of any conventional type, and the inventor doesnot wish to be limited with respect to such detail. The traction wheel is therefore connected to the axle in a conventional way which need not be described in detail.

Aplatform, in The present embodiment of the invention, is produced through the'use of tworearwardly' extending sills 7 and 8 which are supported at their'rear ends by a wheel 9, themounting of which wheel'may be of any suitable type in order that the-platform andparts mounted on itmay travel over a field while dragging the 'weeding mechanism, as will be presently explained.

I Preferably the platform is supplied with an operatofisseat mounted in appropriate manner in such proximity to atoothed' segment 11 and a lever 12 as to permit the so operator when seated. to manipulate the lever. The lever" may have an appropriate detent that 'may enter the spaces between the teeth of the segment for the purpose of holding the lever at different positions of adjustment. A link 14; is pivotally connected to a the lever, and the said link is connected to an arm 16 of a rockshaft 17 which is rotatable in appropriate bearings such as" 18 anchored on the platform. 'The rock shaft is provided with arms 19, each of which is connected by a link 20 to an arm 21 attached to a bar 22. The bars are separated from each other at their inner ends and they extend outwardly to approximately the ends of the axle.

The bars constitute anchorages for the beams 23 which extend rearwardly from the bars .and have downwardly curved portions, and a weeder blade 24 is attached to a plurality of the beams that are mounted on each bar. In other words, a plurality of beams of identical construction are anchored to each bar, and the plurality of beams of each bar carry a blade such as 24.

As shown in Fig. 2, he inner ends of'the blades lap each other and they have angularly disposed parallel portions which serve to insure proper weeding of'the soil throughout the width of the machine. The bars 22 are connected by flexible couplings such as links 25 to the axle or such structure associated with it as may constitute an anchorage for the hooks 26 which the links 23 engage. The weight of the blades and their mountings is to a degree counterbalanced by a spring 27 that is connected to the arm 16 and an anchoring bracket 28. A spring may be provided for each arm, although this detail may be changed to suit particular requirements, but it is the purpose of the inventor that the spring or springs shall be of such strength as to nearly counterbalance the blade structure and require only anominal effort on the part of the operator when the blades are to be raised. The blade elevating mechanism when it is locked also serves to prevent the blades from being driven too far into the soil being treated.

In the modification shown in Fig. 4, only slight changes are made with respect to the arrangement of parts, and it will be seen that the segment 11, the lever 12, the link 14, the arm 16, the shaft 17 and the hearing 18 are very nearly the same as parts heretofore described in connection with the device shown in Figs 1 and 2, there being only a slight change in the angularity of parts or the connections. The detailed illustration of the modified construction is such that a reading of the disclosure hereat angles to the first mentioned arm, bars, means for loosely connectlng the bars to a portion of the wheeled structure, a series of beams on each bar extending rearwardly therefrom and having downwardly curved ends, a weeding blade connected to each series of said beams, an arm attached to each bar at approximately its longitudinal center, and a connection between one of the second mentioned arms and one of the last mentioned arms, whereby motion of the second mentioned arm is communicated to the bar for elevating the weeder blade of the bar being-manipulated. 1

2. In a weeding machine, a wheeled platform, a toothed segment thereon, a lever adapted to be operated in conjunction with the segment, a rock shaft rotatably mounted transverselyof the platform, an arm thereon, a link connecting the said arm to said lever, arms carried by the said rock shaft at angles to the first mentioned arm, bars, means for loosely connecting the bars to a portion of the wheeled structure, a series of beams on each bar extending rearwardly therefrom and having downwardly curved ends, a Weeding blade connected to each series of said beams, the inner end of each blade being angularly disposed with respect to the main portion of the blade and the angular portions extending parallel to each other, an arm attached to each bar at approximately itslongitudinal center, and a connection between one of the second mentioned arms and one of the last mentioned arms, whereby motion of the second mentioned arm is communicated to the bar for elevating the weeder blade of the bar being manipulated.
