SPECIFICATION forming part of Letters Patent No. 444,366, dated January 6, 1891.

Application filed October 27, 1888. Serial No. 289,270. (No model.)

To all whom t may concern:

Beit known thatI, FRED.THEoDoENE1TscH, a citizen of the United States, and a resident of Houston, in the county of Harris and State of Texas,have invented certain new and useful Improvements in Cultivators; 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, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

Figure 1 of the drawings is a representation of a top view of the cultivator. Fig. 2 is a longitudinal vertical sectional view of the same. Fig. 3 is a detail view. Fig. et is a side view of the cultivator. Figs. 5, 6, 7, 8, 9, 10, and 11 representdetails of the parts.

This invention has relation to cultivatingmachines for cotton or corn; and it consists in the construction and novel combination of devices, as hereinafter set forth, and pointed out in the appended claims.

In the accompanying drawings, the letter A designates the outer or main frame, which is of rectangular form and is provided with the journals B, on which the wheels C turn. These wheels serve for transportation, and also gage the depth of work of the cultivating-wheels. The main frame is constructed with posts a, rising from the sill-frame and supporting the top frame b, on which are secured the boxes c for the shaft d of the pinion and hand-wheel W.

Shutters f f are arranged in series around the frame to cover in the cutters or cultivator-wheels and prevent accident therefrom.

The middle side posts are provided with the channeled slideways D, in which play the flanges g of the racks 7c, which extend downward and are secured to the inner or adj ustable frame F, which is of iron. This frame is rectangular and is provided with the side boxes h to receive the ends of the axles of the cultivator-Wheels E and G, said axles being secured by the outer and inner nuts o fc. The rear transverse bar of this inner frame is perforated at intervals, as at k', to receive the bolts which secure the scrapers H in position, the bar being notched, as at Z, to

form seats for the ends of said scrapers and prevent them from turning. .Each rack 'k is provided with-a perforated lug or tenon m, to which the transverse brace I is bolted and serves to hold the racks steady. The inner frame is provided with two axles, and the distance between them is such that the blades of the cultivator-wheels, which have an alternating arrangement, pass each other without striking, as indicated in the drawings.

The wheels E are socket-wheelsthat is, each wheel consists of a circular bodyhaving a hub portion and spokes and a rim portion n, which is formed with a series of sockets s, adapted to receive the tenons t of the blades L. The bladeL is of triangular curved form, having the forward concave edge e', the rear convex edge z', and the concave shoulder z, from which the tenon t springs. The concave edge e' is sharpened, as shown in the drawings, and the tenon is perforated to receive the securing-bolt which also passes through perforations of the socket-walls.

Sometimes I prefer, instead of the cuttingblades above described, to use flanged blades, which will raise or turn the soil on each side. This blade, being otherwise similar to the cutting-blade described, has on each side an oblique chord-ange p, which extends along the middle portion of the rear or convex part of the blade and is provided with internallybeveled edges extending forward.

The cultivating-wheels are designed to turn on the axle, and are separated to run at proper intervals apart by means of sleeves w.

Usually I prefer to use the cutting-blades L on the forward axle and the turning-blades T on the rear axle in opening up the ground, and in this connection, when a hill is to be formed, hilling-shovels extending back from the main frame serve to gather the earth toward the mediam line of the path of the machine. These shovels are vhinged tothe inner sides of the long sill-bars of the frame by staple-hinges, and each is provided with a branch shank g', which has a series of perforations for the passage of the fastening-bolt h', which also passes through one of a series of perforations in the rear transverse bar of the main frame. In this manner adjusting devices are provided to enable the operator IOO to set the shovels farther apart or closer together and to ix them at a higher or lower level, as may be desired.

By means of the rack and pinion the inner frame is allowed to rise or fall to suit the work. The carrying-Wheels form the gage for the Work of the cultivator-Wheels. As the curve of each blade is in the direction of movement of the Wheel-that is to say, down- 'Ward and forward in that part of the Wheel which is about to strike the ground-the blade Works squarely without shock or strain on the tenen, and is designed, therefore, to have durability. Should it, however, become injured, it can easily be replaced with a new blade.

When the machine is passing over roads or in transportation, the inner frame is raised so that its Wheels are clear of the ground, and it is secured in raised position by stron g hooks or other common fastenings.

Having described this invention, what I claim, and desire to secu re by Letters Patent, is-

l. The combination, with the main frame and its Wheels, of the inner frame and its F. T. NEITSCH.
