BYRON C. BRADLEY, OF CHICAGO, ILLINOIS, ASSIGNOR TO FURS'I 8t BRADLEY MANUFACTURING COMPANY, OF SAME PLACE.

CULTIVATOR.

SPECIFICATION forming part of Letters Patent Nd. 293,557, dated February 1.2, 1884.

Application filed April 30, 1883.

To all whom, it may concern:

Be it known that I, BYRON C. BRADLEY, residing at Chicago, in the county of Cook and State of Illinois, and a citizen of the United States, have invented a new and useful Improvement in Cultivators, of which the following is a full description, reference being had to the accompanying drawings, in which- Figure 1 is a top or plan view; Fig. 2, a side elevation; Fig. 3, a section on line w of Fig. 1, looking toward the draft devices; Fig. 4, a detail showing the form of the hanger to which the hitch is made.

This invention relates to the hitch of cultivators; and it has for its objects to secure a.

hitch to correspond to the height of the team and the running-depth of the shovels, and at the same time have the devices also perform the work of equalizing the draft; andits nature consists in the devices and combinations of devices hereinafter described, and pointed out in the claims, for attaining the objects named.

In the drawings, A represents a draftevener or double-tree, made of wood or other suitable material, either in the form shown or any other suitable form,

B is a crossbar, of wood or other material, secured to the under side of the tongue by bolts, clips, or otherwise, so as to be in line, or nearly so, with the draft-evener or doubletree A, which is mounted above the tongue and supported on a cross-piece, 13, secured to the tongue, or in some other suitable manner held in position so as to turn or swing on its bolt or pivot a. The draft-evener A and the crossbar 13 each project on each side of the tongue [the required distance to bring their ends in line with the point where the hitch is to be made.

C represents hangers, one 'for each end of the draft evener or double tree A. Each hanger is made of a pieceof flat metal or other suitable material, and has at its upper end, as shown, a slot, 0, for the passage of a bolt or pin, 0, by means of which it is connected with the end of the draft-evener or doubletree, and each hanger isalso pivoted to the end of the crossbar B by means of a pin or pivot, d, so that it can turn or swing on this (No modelJ' pivot as the draft-evener or double-tree turns 6 of the hangers C, and its other end is secured in any suitable manner to the single-tree.

E represents the single-trees, one for each side of the cultivator, as usual.

F is the tongue, which, as shown, is what is termed a split tongue, but may be of some other form.

C is the axle-tree, to which the rear end of the tongue is secured in any suitable manner,

and which is to be provided on each side with a suitable spindle for the wheels.

The draft-evener or double-tree is located on the tongue at the proper 'pointfor the attachment of the horses on each side, the horses being attached to the single-trees E, as usual, and the operation-is as follows: The hitch has to be higher or lower to suit different depths of plowing and the height of the team, and the proper height for the hitch is secured by connecting the rod or hook D in the proper hole to bring the draft at the proper point for the depth of plowing and the height of the team. The hitch being made to the hangers C, and each hanger being independently pivalso loosely connected with the ends of the draft-evener or double-tree A, it will be seen that the movement of either hanger gives a reverse movement to the opposite hangerthat is to say, if the lower end of the hanger on one side is drawn forward from any cause the lower end of the opposite hanger will be forced backward, for the reason that the end of the draft-evener or double-tree to which the upper end of the hanger, the lower end of which is carried forward, is connected will be forced backward, forcing the opposite end forward+and by this arrangement it will be seen that the draft will be equalized, as just so much as the draft is increased on one side it is decreased on the other. a

oted to the end of the cross-bar B, and being It will be seen that the hangers C not only furnish the means for changing the hitch to suit the draft and the team, but at the same time they furnish the means, by their pivotal connection and the attachment of their upper ends to the draft-evener or double-tree, by

- which reliable and perfect equalization of the draft is secured, dispensing with the use of double devices for securing these two objects of proper hitch and equalizing the draft and accomplishing both objects by one and the same means.

As shown, the bar B extends across underneath the tongue; but it is evident that brackets or arms projecting out from the tongue could be used forv furnishing the support and pivotal connection for the hangers.

The free swing of the ends of the doubletree is permitted by the slots in the upper ends of the hangers, and this free swing is necessary to have the double-tree act as a draftequalizer, and any other connection of the upper end of the hangers with the ends of the double-tree which will allow free swing than the slot and pin can be used-such, for instance, as a slotted or grooved plate on the hanger, and a pin with a button or head on the end of the double-tree working in the slot or groove; or the plate could be on the end of the doubletree and head or button in the hanger, so long as a free swing was produced.

W'h'at Ifclaim as new, and desire to secure by Letters Patent, is

1. The hangers O, loosely connected with the draft-evener, and having a central pivotal connection with a fixed support, and constructed to receive adj ustably the draft-connection, substantially as described.

2. The combination of the draft-evener A, support B, the hangers O, pivoted to the sup port and connected with the draft-evener, the single-trees E, and hooks or rods D, connecting the single-trees to the hangers, substantially as described.
