JAMES F. KING, OF AUBREY, KANSAS.

CULTlVATOR-SHOVEL.

SPECIFICATION forming part of Letters Patent No. 247,658, dated September 2'7, 1881. Application filed July 2, 1881. (No model.)

To all whom it may concern:

Be it known that I, JAMES F. KING, of Aubrey, in the county of Johnson and State of Kansas, have invented a new and useful Improvement in Cultivator-Shovels and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification, in which-- Figure 1 is a front view of my improved cultivator-shovel. Fig. 2 is a longitudinal section on line :0 x of Fig. 1. Fig. 3 is a section on line y y of Fig. 1; and Fig. 4 is a similar section, showing the employment of alap-joint connection between the plow-point and upper plate.

Myinvention relates to improvements in cultivator-shovels; and it consists in the peculiar construction and arrangement of the parts, as hereinafter more fully set forthand claimed.

In the accompanying drawings, a represents the 7 upper plate of my improved cultivatorshovel, the lower straight edge, I), of which is beveled for a purpose hereinafter described.

The plate a, is provided with holes 0 0, through which the ordinary bolts pass which secure the shovel to the standard of the cul tivator. The plate a is also provided with holes dd near its lower end for the passage of bolts e e, which also pass through holes in a supporting-plate, h, lying under the plate a and projecting below its lower end to support the plow-point. The heads of the bolts 0 e are provided with conical heads countersunk in the holes 1 d, so. that the. heads of the bolts are flush with the upper face of ,the plate a. The ends of the bolts are riveted to the sup.- porting-plate h, whereby the latter is securely attached to the lower face of the plate a. A hole, g, is also made in the supporting-plate h, registering with the hole 0 in the upper plate, for the passage of one of the bolts which secure the plate a to the standard, whereby the supporting-plate is secured directly to the standard. By this construction it will be seen that the upper plate, a, and supporting-plate h are securely attached to each other, and

each is bolted to the standard.

It represents a plow-point, preferably made of steel, of the usual form at its lower end. The upper straight edge, l, of the plow-point is beveled, so as to fit against the beveled edge I) of the plate a.

Instead of con necting the upper plate, a, and plow-point by a beveled joint, a lap joint, as shown in Fig. 4, may be employed.

at represents a hole made in the plow-point for the passage of a screw-bolt, 12, having a conical head countersunk in the plow-point, so that its head will be flush with the upper face of the plowpoint. The screw -bolt n also passes through a hole, 0, in the supportingplate h, made angular at its lower end. The screw-bolt n is held in place by a nut, 10, on its lower end.

By this construction, it will be seen that the point is securely held in position by means of its beveled or lap joint connection with the upper plate and the single bolt passing through holes in the plow-point and supporting-plate, and that when a plow-point is worn or broken it can readily be removed and a new plow-point substituted for it. It will also be seen that in the operation of the shovel the principal strain isborne by the supporting-plate h, which in my construction is secured to the upper plate, a, to the plow-point, and to the standard, and if the supporting-plate is broken it can readily be removed and another substituted for it.

I am aware of the patents for plow-points granted to S. M. White and I. A. Francis, dated August 13, 1878, No. 206,910; H. O. Beebe, dated January 6, 1880, N 0. 223,309, and H. A. Ridley, dated April 26, 1881, No. 240,766;

and I therefore lay no claim to such construction, my invention being confined to the details of construction whereby the upper plate, the plow-point, and the supporting-plate are each made of a separate and distinct plate, which may be replaced if broken, each plate being secured to both the others, and the upper and supporting plates riveted to each other, and both adapted to be secured by a bolt passing through both to the standard of a plow.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is--- The combination, with the upper plate, a, \vnrdly, and hole m, screw-bolt n, and nut 19, havingits lower straightedge, I), beveled downsubstantially as described, and for the purpose 1o wardly and provided with the holes 0 e d (I, set forth. of the snpportingplate h, riveted to the upper JAMES F KING 5 plate and projecting below it, and provided with the hole 0 and hole g, registering with \Vitnesses: the lower hole, 0, of the plate a, plow-point 7a, THOMAS 'l. HARRISON, provided with a straight edge, I, beveled up- A. M. YOUNG.
