Letters Patent No. 108,945, dated November v1, 1870.

lMPROVElVIENl IIN CULTIVATORS.

The Schedule referred to in these Letters Patent and making part of the same.

To all 'whom it muy concern:

Be it known that l, DANIEL C. STOVER, of Lanark,

Ain the county of Carroll and State of Illinois, have invented certain Improvements on Oultivators; and I do hereby declare that the following is a full, clear, and exact description thereof', reference being had to the accompanying drawing, making part of this specitication, in which- Figure 1, plate 1, is an elevation of one side of my improvedv cultivator.

Figure 2, plate 1, is a top view of the cnltivator.

Figure 3, plate 2, is a section, in detail, of the improved devices.

Figures 4, 5, and (i, plate 2, are views, in detail, showing my mode of attaching the shovel-beams t the frame of the machine.

Figure 7, plate 2, is a view of my improved brace.

Similar letters ot' reference indicate correspondingr parts in the several figures.

This invention relates to innnovemcnts ou cultivators which have their shovel-beams `attached to carriages.

The nature of my invention consists y First; in a forked brace for connecting a shovelstandard to the beam in such manner as to allow the adjustment of the said standard to any desired angle with respect to the beam, and also to allow the detachment of the standard from such brace should the shovel meet with an obstruction in its path, which would be liable to break or derange the machine, as will be hereinafter explained.

Second, in applying the. adjustable eye-bearing, which connects the shovel-beam to the carriage, to a long tube or sleevel which is upon an inner cylindrical extension of the limb of the carriage, whereby-a vlong tubular bearing is. obtained for said eye-bearing, upon which thc latter can be adjusted laterally, for setting the shovel-beams at diicrent distances apart, as will be hereinafter explained.

To enable others skilled in the art to understand my invention I will describe its construction and operation.

In the accompanying drawing, Jigs. l and 2, I have represented my improvement applied to a two-wheel carriage.

.This carriage consists vof two wheels, A A, applied on axles C', which extend outwardly from twouprights, C C, 011 the upper ends of which is secured an axle-tree or horizontal cross-bar, D.

On this bar is secured a bifurcated draft-pole, l', carryingr loops a a on its rear entended ends, and having theaxle-uprights C C secured to it by brace-rods c c1 c2, as shown, or in any other suitable manner.

Such acarriage is especially adapted for use in cultivaters for tall crops, as the cross-bar l is lelevated sufficiently to clear the rows of plants under cultivation and allow the wheels and horses to travel in the furrows between the rows.

In order to attach the shovel-carrying beams D to a frame with an elevated cross-bar B, as above described, rod-extensionsl? I are applied to the inner ends ot' the short axles C C, on which rods tubes tare loosely applied, and kept in place by nuts p, screwed on the inner ends of' said rods.

These tubular bearings t should be of such lengthV respectively, as will allowthe required lateral adj ustment of the shovel-carrying beams.

On each tubular bearing t, au eye-bearing, J, is placed, and secured to it firmly by means of the setscrew h, or by any other device which will admit the said bearing J to be loosened from its bearing t, for adjustment.

The Aeye-bearing J receives on its top and bottom the plates Gr G, which are connected to the said bearing by a vertical pivot, lo.

The plates Gr G are secured permanently to the front end of the shovel-carrying beam D.

By means of the eye-bearing J and its tube t rocking ou the horizontal rod I, and the vertical pivotal connection I.: of the beam D to the said eye-bearing J, it will he seen that the beam D is allowed to receive universal movement.

The tube t is prevented from receiving endwisc movement on the rod I bythe cud abutments shown in figs. 4 and 5, but this tube is allowed to oscillate freely on said rod l), and thereby it will afford a long support forthe eye-bearing J, which is secured .to it.

'Ihe eye-bearing can be adjusted on its tube either toward the right or left hand by loosening the clampscrew h.-

The shovel-carrying beams, their handles or stilts F, and the standards E, and shovels c, may all be constructed in the usual well-known manner. The hooks a on the beams D are used-for suspending these beams and their attachments from the loops a on the rear ends of the draft-pole, and the cross-rods j' f, and block f1 are used toconnect the rear ends ofthe beams l) D together.

Ilach one-of the shovel-stalulards E is connected at its upper end to a beam, D, by means of a single transverse bolt, which will allow the standard to swing longitudinally as though it was pivoted.

Below the said pivot-bolt the standard is connected by a transverse bolt, i., to the inclined brace g, which extends forward and upward and is connected to beam D by a transverse pivot-bolt, n.

Each brace g has van ,e ye, gz, formed on one end andv a fork, g, formed on its opposite end; and by means of a washer and the bolt and nut fi, the forkend is secured to the standard, so as to resist any ordinary backward thrnstagainst the shovel; but should the shovel meet with an obstacle in its path which would be liable to derange or break the ma chine, thc attachment will give way and the bolt l1l will slip ont et' the slot n: and allow the shovel to fall back. y

The slot :1: is also made ot such length as will allow the standard to be adj usted and set at different angles with respect to the beam D;

I am well aware that closed slotted bra-ces, wooden pins with eye-braces, and Vother like devices have been employed in combination with drill-teeth, cultivatorstandards, and plow-standards, and I do not claim as my invention such devices.

I have constructed a brace, g, with an eye, g2, on one end and an open slot or fork on the opposite end, which open slotted end will allowr au adjustment ot' the cultivator-beam, so that it can be set to Work at different angles, and also allow the beam to become detached from the brace when subjected to extraer'- dnary strain.

Having thus described my invention,

What I claim as new, and desire to secure by Letters Patent, is-

il. The combination of the short sliding eycbearing J, long tubular bearing t, and retail'iing-screw 7i, substantially as described.

2. The short axle-extensions I?, tubes t, braces c c1 c2, and forked tongue, combined substantially as and for thc purpose described.

3. The tubular eye-bearing J with perforated ears,V

in combination with the shortaxle-extensions P, tnbe zf, plates G G, and beam I), substantially as described.
