ATTACHING DEVICE FOR CULTlVATOR-BLADES.

SPECIFICATION forming part of Letters Patent No. 791,853, dated June 6, 1905.

Application filed March 20, 1905. Serial N0. 251,051.

To all whom it may concern.-

Be it known that I, ARTHUR M. WORD, a citizen of the United States, residing at Rome, in the county of Floyd and State of Georgia, have invented certain new and useful Improvements in Attaching Devices for Cultivator- Blades; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improved means for attaching cultivator-blades.

The object-of the invention is to provide an attaching device of this character which will securely hold the blade of the cultivator in place and prevent the same from turning upon the standard of the plow.

With this and other objects in view the invention consists in certain novel features of construction, combination, and arrangement of parts, as will be hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a side elevation of the lower end of the plowstandard, showing the application of the invention. Fig. 2 is a front elevation of the same. Figs. 3 and I are respectively side and front elevations illustrating a different manner of applying the devices,and Fig. 5 is a detail perspective view of the attaching device removed from the standard.

Referring more particularly to the drawings, 1 denotes the standard, which may be of any suitable form, but which is here shown and is preferably constructed by bending a bar of iron upon itself in the form of a loop. To the lower end of the standard 1 is connected the usual or any desired form of cultivator-blade 2. The blade 2 is preferably secured to the standard 1 by means of a bolt 3, which passes through said blade and through the standard 1.

bolt 3 is adapted to be screwed a tail-nut 4:.

On the bolt 3, between the nut 4 and the rear side of the standard, is disposed a washerplate 5, said plate being provided with an elongated aperture 6, through which the bolt 3 passes, and is also provided adjacent to the ends of the same with laterally-projecting lugs Onto the threaded end of the 7. The lugs 7 are adapted to extend through the standard 1, the outer ends of the same projecting into a slot 8, formed in the blade 2, thereby firmly holding said blade against rotation upon the bolt 3.

In Figs. 3 and 4 of the drawings is shown a different arrangement of the washer-plate 5. In this instance the plate is arranged upon the outer side of the cultivator-blade, between the same and the head of the bolt 3, the lugs 7 on said plate projecting through the slot 8 in said cultivator-blade and into the standard 1. In either application of the washer-plate the cultivator-blade will be firmly held against rotation upon the bolt 3.

The washer-plate 5, as herein shown and described, is simple and inexpensive in construction, eflicient in use, and well adapted to the purpose for which it is designed.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the inven tion will be readily understood without requiring a more extended explanation.

Various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

An attaching device for cultivatorblades comprising an apertured rectangularlyformed washer-plate adapted to be engaged by the blade-attaching bolt of the cultivator,

laterally-projecting parallel lugs formed on said plate to enter the standard of the cultivator and to engage a slot formed in the cultivator-blade, thereby holding the latter against turning on its attaching-bolt, substantially as described.

- In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.

ARTHUR M. WORD.
