Application led October 1,

To all whom t may concern.' v

Be it known that I, HERMAN HANSON, a citizen of the United States, `residing at Garfield,V in the county of Douglas and State of Minnesota, have invented certain new and useful Improvements' in lVeeders and Pulverizers7 of which the following is a specification. v

This invention relates to a weeder and pulverizer attachment for cultivators and has for its principal objectto provide a device of this nature which will be efficient and reliable in operation and will be readily placed in and out of engagement with. the ground when so desired.

Another object of the invention is to provide simple and efficient means for attaching the device to a cultivator ofl conventional construction, said attaching means being -adjustable so as to accommodate the various differences found in conventional cultivators.

With these and numerous other objects in view the invention comprises certain novel features of construction and the arrangement and combination of parts aswill be hereinafter more fully described and claimed.

In the drawings Figure 1 is aY plan view of the device showing the same attached to a portion 0f a cultivator;

- Figure 2 is a fragmentary side elevation ofY the rear portion of the device;

Figure 3 is a longitudinal vertical section taken through the device; and,

Figure 4 is an enlarged section taken on the line 4-4 of Figure 1 `looking in the direction of the'arrow.

Referring to the drawing in detail it will be seen that 1 designates a cultivator of conventional construction which is usually provided with the rear diverging arms `2 and as isi well known the angle formed by these diverging arms 2 varies considerable inva` rious cultivators now commonly in use and it is the purpose7 therefore, of the present invention to provide an attachment which' is capable of being secured to practically all conventional cultivators having a portion somewhat similar to that illustrated to advantage in Figure 1.

This attachment consists of the beam 3 having fixed thereto a vplurality of curved fingers 4 each of which is provided with a shank 5 bent in L-shape so as to t over the top of the beam 3 andk along the forward side thereof. These Shanks are held in Speccaton'of Letters; Patent. Pafentedeuine 27',

place by means of eye bolts 6l which pass i through the beam- 3. U-shaped rod 7 i is fixed to each end of the beam 3 by having one leg thereof rivetedto the terminals of the beam as shown at 8 and the other leg 9 projecting a short .distance into the beam if .n

so desired.YY A coil 'spring 10 is disposed on theA rod 7 and has fori its fpurposeto noi`` provided with a longitudinally extending slot 13 and an eye 14 for yreceiving the rod 1 7. Theleaf 13 :is provided atV its terminal with a suitable eye which is in engagement p with an' eye 17 carried on a brace rod 18. The other end of the brace rod 18 is provided Vwith an aperture for receiving the bolt 19 which passed through the slot 13 and thus the angle between the leaves 12 .and 13 may be varied to accommodate the angle of the diverging arms 2. It will furthermore be seen that the attaching means is adjustable longitudinally of the beam 3 since the spring 10 maybe compressed for this purpose.

the Vdepending arm22 is attached to a coil spring 23 which is also `attached to a bar; 24 or any `,other suitable part of the culti-v vator 1 for the purpose of normally holding the fingers in engagement with the ground.

A flexible member 25 is povided with a snap f hook 26 at its'end and is suitably attached to the upstanding arm21'whereby this `flexible member may be pulled toward' the cultivator so as to rotate the beam thereby lifting the fingers 4 outV of engagement with the ground at' the same time expanding thercoil spring 23 and the snap hook 26 may be placed in engagement with any portionof the Vcultivator so as to keep thev fingers 4 out of engagement with the ground as long as desired. ,f

. e5 l By having the rods 7 passing through From the foregoing description taken in connection with the accompanying drawing, the construction and the operation of the attachment will be readily understoodwithout more extensive explanation. As numerous changes in form, proportion and the minor details of construction may bel resorted to without departurev from the spirit of this invention, l do notwish to limit the construction herein shown and described other than as claimed.

Having thus described my invention what I claim as new is:-

1 .In combination, a cultivator provided with rearwardly extending diverging arms, an attachment therefor consisting of a beam,

U-shaped rods secured to the ends of the beam, springs mounted on the rods, attaching means pivotally mounted on the rods and including a pair of hinged leaves one of which being provided with a slot, means for attaching the other leaf rigidly to the arms of the harrow, a brace rod pivotally mounted on the last mentioned leaf, and a bolt passing through the vslot of the other leafV
