Specification of Letters Patent.

Application fildnovember s, 1906. Serial No. 342,245.

Be it known that I, WILLIAM L. PAUL, a resident of South Bend, in the county of St. Joseph and State of Indiana, have invented certain new and useful Improvements in Cultivators and I do hereby 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.

My invention relates to improvements in wheeled cultivators, the object of the invention being to provide a cultivator having a tongue, with improved construction of gang shovel mounting to provide an improved draft equalizing, and the invention consists in certain novel features of construction and combinations and arrangements of parts as will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings, Figure 1 is a plan view illustrating my improvements. Fig. 2 is a view in side elevation, and Fig. 3 is a front view, and Figs. 4 and 5 are views of a modification. 1

1 represents the tongue of the cultivator, to which a bracket casting 2 is secured, and this casting provides parallel bearings 3, in which arch halves 4 are mounted and held against lateral movement in the bearings by collars 5 and set screws 6, but permitted free rotary or swinging movement, for a purpose which will more fully hereinafter appear. The outer ends of these arch halves 4 constitute axle stubs for the wheels 7, and between the wheels and upright portions of the arch halves, my improved brackets 8 are located and will now be described in detail.

A sleeve 9 is located on the arch half and the bracket 8 has a split sleeve 10 securely clamped on the sleeve 9 by-screws or bolts 12, and a key 11 on sleeve 9 enters a key way in one of the sections of the splitsleeve 10 to compel the sleeves to turn together on the arch half. A rearwardly rojecting vertical yoke 13 is made integra with one of the sleeve sections 10 and supports a vertical sleeve 14 secured in the yoke by a bolt 15 and nut 16, and a split bracket 17 secured on the forward end of a shovel beam or frame 18, is securely clamped on the sleeve 14.

The cultivator gang 18 carries two or more shovels of any desired construction, and the gang at each side of the machine has one inwardly and rearwardly projecting handle 19, the two handlesterminating in convenient reach of an operator on the ground, to enable him to readily manipulate both shovel gangs while walking. The term shovel gangs is intended to be understood as sufhciently broad to cover any form of frame carrying furrow opening devices and is not to be restricted to shovel plows. I

The rear end of the tongue 1, has hooks 20 secured to its opposite sides and these hooks 20 are adapted to engage perforated lugs 21 adjustably secured to the frames 18 for supporting the shovel gangs in elevated position.

22 represents an evener bar pivotally secured, midway between its ends, to a bifurcated casting 23 secured to the bottom face of tongue 1. To the ends of this evener bar 22, bifurcated brackets 24 are pivotally secured, and the latter are connected by rods 25 with brackets 26 on the upright portions of the arch halves.

' 27 represents draft irons which may be of various constructions connected to the arch halves. The form shown constitutes a fork or yoke, straddling the wheel and secured to arms 28 on the arch halves at opposite sides of the Wheel.

Counterbalance springs 29 are provided for both gangs and connect lugs 29 on the upper portions of the arch halves with lugs 29 on sleeves 8 to assist in lifting the shovel gangs to their inoperative position supported on the hooks.

The operation of my improvements is as follows :'A draft animal is hooked to each draft yoke 27 and it will be seen, that when one animal advances ahead of the other, he carries his shovel gang with him and also one half of the load of the frame of the cultivator by virtue of the evener bar 22, as the forward movement of one arch half will swing the evener bar and move the other arch half rearward and the draft is thereby equalized. When the shovel gangs are swung up and caught onto the hooks 20, both arch halves will be held against swinging movement and the cultivator can be readily transported from place to lace.

In the modification illustrated in Figs. 4 and 5, the arch halves 4 are shown connected to a frame and while the term frame is employed in the claims as that part to which the arch halves are connected it is to be understood that the term is intended to cover and include a pole or tongue as well.

A great many slight changes might be made in the general form and arrangement of the parts described Without departing from my invention, and hence I do not restrict myself to the precise details set forth but consider myself at liberty to make such slight changes and alterations as fairly fall within the spirit and scope of my invention.

Having fully described my invention what I claim as new and desire to secure by Letters Patent, is

1. In a cultivator, the combination with a pole, and two arch halves, each having a spindle portion for a wheel, of a shovel gang connected With the spindle portion of each arch hall, a draft iron also attached to the spindle portion of each arch half, a bar ivotally connected between its ends wit 1 the ole, and rods connecting the ends of said ar with the arch halves, the connection of said rods with the arch halves being independent of the connection of the draft irons with the s )indle portions of the arch halves.

2. n a cultivator, the combination with a tongue, of arch halves pivotally connected With the tongue, wheels supporting the outer ends of the arch halves, sleeves on the arch halves, brackets having split sleeves clamped on the arch halves, vertical sleeves supported in the brackets, shovel gangs secured to the vertical sleeves, lugs 011 the sleeves located on the arch halves, lugs on the upper port ions of the arch halves, and coiled springs connecting the lugs on the upper portions of the arch halves with the lugs on the sleeves.

In testimony whereof, I have signed this specification in the presence of two subscribing Witnesses.
