IMPROVEMENT IN CULTIVATORS.

Specification forming part of Letters Patent No. 107,069, dated September 6, 1870.V

I, JAMES R. LITTLE, of Galesburg, in the county of Knox and State ot Illinois, have invented certain Improvements in Cultivators, of which the following is a specification:

Nature and Objects of Invention.

The nature of my invention relates to improvements in securing the shovels or spades of cultivators to the shanks; and the invention consists in a hollow semicircula-r metallic plate, bolted securely to the rear side ot thel shovel, a sliding button titting the cavity be,- tween said plate, and the shovel carries a bolt, projec ing through a slot in the plate, by

means of which, with a nut, the shovel may Description of the Accompanying Drawing.

Fig. 3 is a side elevation of a shovel with the plate B of Fig. l attached. Fig. 4 is a rear elevation of the plate B detached. Fig. 5 is a side eleva-tion of the plate C of Figs. l and 2 detached.

General Description.

A is an ordinary cultivator shovel or spade. B is a semicircular plate, with lugs b b at each end, through which rivet-bolts b b pass for the purpose of securing it to the shovel A. The plate B is slotted, as shown at Fig. 4. by B. D is a button or slide, (shown at Fig. 6,) one side of which is curved to correspond with the concave side of the plate B, against which it rests. E is a bolt carried by the button D, and projecting through the slot B', and, being somewhat smaller than thc slot, allows the bolt to move freely laterally, while it may be adjusted vertically, in the slot. The plate B has a recess, B", into which the bolt E is slid for convenience in inserting the button D. C is a metal socket, the lower end grooved to iit the face of the plate B, and pierced with a hole,through which thebolt E passes, as shown in Figs. l and 2. The rear side of the socket C, above thebolt E,is deeply grooved for the reception of the standard H, which is pivoted therein at its lower end by the bolt J. L L' are holes in the upper end of the socket C. A wooden pin passed through the hole L will secure the shovel at an angle to the shank. (Shown by Fig. l.) By withdrawing the pin and bringing the upper end of the socket C forward until the hole L is brought to coincide with the hole L" in the shank H, the position of the shovel A may be brought nearer vertical. Sis a square metal plug, seated in one of the jaws of the socket C, and pierced with a hole for the reception of the bolt J, in such manner that when the tap j is tightened up the head of the bolt J, resting on the plug S, alone will draw the plug against the side of the shank H, as shown at Fig. 7, thereby furnishing a sure and simple means for holding rmly the shank H between the two solid jaws C C;

The operation of my invention is deemed obvious from an inspection of the accompanying drawing.

In case a wooden shank is used,it should be cut out at the lower end to adapt it to the face ot' the plate B, and be pierced witha hole for the bolt E, when, being placed in position by means of the nut on the bolt E, it may be held securely in place.

Then the nut on bolt E is loosened the bolt and button D may be moved upward or downward in the slot B', for the purpose of adjusting the position of the shovel A vertically, and the bolt E may be moved laterally in the slot B', for the purpose of adjusting the angle oi' the shovel A to the line of progression of the cultivator, for the purpose of throwing the dirt to or from the row of plants.

lNhen an iron shank is used, as shown in the drawing, the plate C may be adjusted on the plate B in the same manner and for the same purposes last described for a wooden shank.

An additional adj ustment is secured between the plate C and the iron shank H. When the pin L is withdrawn, the lower end of the shovel A may be moved forward or back, Swingin g on the pivot J, and the pin L, by being Inserted in the different holes L L', may be made to adjust the vertical angle of the shovel A with the ground.

The pin used in the holes L L', being wood, will break when a solid obstruction is struck by the shovel A, and the shovel then swinging back on the pivot J will save breakage at any other pla-ee.

Claims.

I claim as my invention- 1. The plate B, constructed substantially as described, arranged with the shovels and.v
