SPECIFICATION forming part of Letters Patent No. 271,791, dated. February 53, 1883,

V Application filed September 18, 1882. (No model.) v

To all whom it may concern:

Be it known that I, EDWIN CHILDREN, of

East Dubnqne, in the county of Jo Daviess ing drawings, and to the letters of reference marked thereon.

. The object of the invention involved in the snbject-matter of this specification is to produce a more perfect adjustment-of the cultivator-shovel upon its standard. 'One of thegreat difficulties in the way of the successful operation of cul'tivators is to make the shovels scour under all "circumstances. The couplings in common use provide means for turning the shovel in the seat in which it rests, and when turned to either side the friction is largely thrown to the side to which it is turned, and the shovel is thus placed in an unfavorable position to scour. By means of my improvement, hereinafter described, I am enabled to turn the shovel on the standard, and also at the same time to place its. point in a position so as to distribute the pressure more evenly over the whole surface of the shovel, thereby causing it to scour more perfectly, and tohandle more soil and with less liability to injure the roots of the corn.

To the accomplishment of the above results the invention consists principally in interposing a block or washer between the standard and the shoe or casting to which theshovel is secured, the same to be of the shape and size to conform with and accommodate the various models of such shoes or castings, all as more fully hereinafter described, and pointed out in the claim.

For the better understanding of my inven tion, and to enable those skilled in its relative art to know how to construct and makeuseof the same, I will proceed to descrtbeit with reference to the accompanying drawings. which illustrate the device as adapted for the accommodation of several different forms of the shoe or casting towhich the shovel is secured.

Likeletters of reference indicate correspond ing parts in all the figures.

In the drawings, A denotes the standard of any suitable construction B, a block or washer; O, the shoe or casting to which the shovel is secured; and D the shovel, secured thereto by any suitable means.

In all instances of usage the block or washer B, which may be'constructed of any desirable and'suitable material, rests flush upon the front of the standard A. As shown in Fig. 1, it is providedon its upper surface with a longitudinal concave cavity, a, for the reception of the convex portion of the shoe or casting O, which fits and rests therein.

In the convex portion of the shoe or casting G is a rectangular opening or slot, b through which and an orifice, 0, made in the block or washer B and the'standard A, 011 a line verti-' cal with said rectangular opening, passes a bolt, E. This bolt has a flanged or enlarged upper end, and is screw-threaded at its lower end to receive a washer and nut whereby the several parts are drawn together to their desired position and firmly clamped to the stand- .with its shovel, can readily be laterally ad- By means of the rectangular openingor justed and secured at any angle, for the purpose of turning the soil toward or from the corn, as maybe desired.

In the modification shown in Fig. 2 the construction of the block or washer B is the reverse to that shown in the preceding figurethat is, instead of it being hollowed out or made concave on its upper surface, it is made semi-cylindrical or convex in order to adapt itself to the chambered-out or concave portion of the shoe or casting G, in which it nicely fits. This shoe or casting has also the rectangular opening or slot 1), and the block orwasher and standard have likewise the orifice c for the in sertion ofthe bolt E, by means of which and its washer and nut the-shoe and its shovel can be adjusted and secured, as before described. In the form of the shoe or casting shown in Fig. 3 there is but a slight variance from the construction in that of Fig. 2, and therefore requires but littleor no change in the construction of the block or washer. In consequence of the absence of a rectangular opening or slot in this form of shoe, and owing to the employ- ICO ment of the stirrup or U-shaped bolt, no orifice is required to be made through the block or washer and the standard, but the former is pivotally secured to the latter, and by the stirrup or U-shaped bolt with its washer and nuts the shoe or casting, with its shovel, can be adjusted as readily to be effective as by the forms shown in the preceding figures.

It will be seen that this device is very simple in its construction, costs but little to manufacture, and can be readily modeled to accommodate audjit the various forms of the shoes or castings commonly used in attaching the shovels to the standards of cultivators; and, further, it such standards should be of an uncommon construction, it is evident that the under surface of the device could readily. be
