E'aPECIPICATION forming part oi' Letters Patent No. 298,609, dated May 13, 1884.

Application filed November 9, 1883. (No model.)

To all whom it may concern/.-

Be it known that I, GILPIN MOORE, a citizen ofthe United States, residing at Rock Island, in the county of Rock Island and State of Illinois, 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 theinvention, 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 or figures of reference marked thereon, which form a part of this specification.

I have shown in the drawings herewith, and will herein briefly describe, one construction or organization of one type of the cultivator generally known to the trade as the tongueless cultivator, but my present improvement, which is herein fully described, is applicable to any cultivator of this particular type in which the journals of the supporting wheels are hinged to the central parts or yoke which connects them,and the draft-bars are fixed to the wheel-journals, or the short frames in which said journals are fixed, in such manner that the wheels will swing with the draft-bars and be held in line by the same bars to properly ad vance the cultivator in operation.

In cultivators of this type different means have been used for sustaining the central part or yoke in its elevated position when the plowgangs are suspended thereon; and the object of my present invention is to provide means for sustaining said yoke, which means are always in position for operation when the draftanimals are hitched to the cultivator, and which will not in any manner interfere with the operations of the cultivator, nor with the plants either in moving the cultivator along the rows or turning it at the ends of the rows.

To the end of carrying out the foregoing object my invention consists in a pole or bar hinged to the yoke in such manner as to permit of swinging it horizontally 011 the yoke independently of the wheels and draft-plates, while it will at the same time sustain the yoke in an elevated position, either with the plows in operation or suspended on the yoke for local transportation. The hinged sustaining-pole,

which my invention embraces as its principal feature in the type of cultivator herein referred to, is not an ordinary tongue, in that the draft is not attached thereto, and is not an ordinary guide-pole, in that it is not connected with the cultivator, so as to act as a guide in any manner to the wheels or other parts, its only function being to sustain the yoke, as hereinafter described. As a secondary feature, springs may be used with my improved sustaining-pole in this type of cultivator to exert an upward force on the plowgangs and aid in their manipulation, all as hereinafter fully described.

In the accompanying drawings, Figure l is a perspective of a cultivator embodying my invention; Fig. 2, a side elevation; Fig. 3, a rear elevation of the yoke, wheels, and adjacent parts, and section of the sustaining-pole; Figs. 4 and 5, top plans.

Referring to the drawings byletters, Arep resents the central part or yoke formed of bars a a, rigidly united by plates a a to form an ordinary yoke with an elevated central part.

B B are spindles or journals on which the wheels 0 are journaled. The inner ends of the spindles B are fixed to vertical parts b,which are hinged or journaled to the plates a, so that the wheels 0 may swing laterally with reference to the yoke, as shown at Figs. 4 and 5.

1) D are the draftbars, one of which is fixed at its rear end to each spindle-frame B b in such manner that each wheel will swing with the draft-bar connected therewith.

The yoke A may be constructed as I have shown and described, or in any other ordinary or desired manner, and the wheel-spindles may be hinged to the yoke, as I have shown and described, or in any other desired manner, and the draft-plates may be connected with the wheel-spindles in any desired manner.

I have shown the plow-gangs E hinged to the yoke, as shown and fully described in Letters Patent No. 217,811, granted to me July 22, 1879, and they may be so hinged, or in any other desired manner, and may also be either hinged to the yoke, as shown, or to a projection from the wheel-spindles.

F is a bar fixed at its mid-length to the upper central part of the yoke A by a stirrup, f, and by braces f which braces extend from the bar F to the lower ends of the yoke A.

G G are hooks secured to the rear ends of the bar F.

H is a bar fixed transversely to and on the forward end of the bar F, and is secured by braces h,'which extend from its ends to the ends of the yoke A, as shown. A tension-spring, I, is connected at its rear end with an extension,e, of the joint, by which the plow-gangs are hinged to the yoke, in the same manner as in my aforesaid patent, and the forward ends of the springs I are connected one to each end of the bar F in such manner that the springs exert the ordinary upward force on the plowgangs to aid in manipulating them while in operation, and in raising them to suspend their rear ends on the hooks G.

J is the sustaining-pole, shown hinged near its rear end by avertical bolt, j, to the bar F, so that it may oscillate in a horizontal plane with reference to the yoke A; but I do not limit my claim to this method of hinging the the hinge by which it is connected with the bar F. The forward end. of the pole J is not shown in the drawings; but in operation it is connected with the draft-animals by a neckyoke, or in manner common to the ordinary cultivator-tongue or draft-pole, and will sustain the yoke A in an elevated position when the plow-gangs are suspended on the hooks G, as hereinbefore described for local transportation, for turning at the ends of the rows of plants, and for other purposes. The pole J will not interfere with turning the cultivator in any manner, nor interfere with the various movements and changes of parts relatively to each other, as are common to this type of cultivator. In turning at the ends of rows of plants, and when the wheels are deflected by the draft-animals, as shown by dotted lines at Fig. 5, the pole J will swing with the draftanimals independent of the yoke A, as shown by dotted lines at same figure, and thus permit of cultivating nearly to the ends of the rows, as can be done withthe ordinarytongueless cultivators. When one end of the yoke A is advanced by the draft-animals connected therewith, the pole J will swing and not interfere with such movement of the yoke, as shown at Fig. 4, nor interfere with the operations of the springs, which are arranged, as shown, in

such manner that the lateral movement of the pole J on the yoke or the lateral movement of the yoke relatively to said pole will not affect the springs, nor affect the plow-gangs through any action of the springs; and thus in all the operations of the cultivator, the pole J ,swinging independently of the wheels and of the yoke A, will not interfere with any of the movements, operations, or functions of these parts when combined in the same manner in a tongueless cultivator, while it will sustain the yoke in an elevated position, in order that the plows may be suspended thereon, and in order that the springs may exert an upward force on the plow-gangs without turning the yoke over rearwardly. 7

The plow-gangs may be suspended on the yoke A, as I have shown by dotted lines at Fig. 2, or in any other desired or ordinary manner.

I am aware of the use of springs in cultivators of the class shown in my patent of July 22, 1879, No. 217,811, and do not hereinmake any claim that would prevent the use of sp rings in that class of cultivators; but,

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

1. In a cultivator, in combination, a central part or yoke,A,awheel and draft-plate hinged to each end of said yoke, and adapted to swing relatively thereto, substantially as described, plow-gangs, a pole hinged in front of the yoke to swing laterally in reference thereto and independently of the wheels, and adapted to sustain the yoke in an elevated position, and springs connected at the forward ends with the yoke A or a projection in. front of the yoke, which projection is connected rigidly to the yoke, and at their rear ends connected with the plow-gangs and adapted to exert an upward force thereon, substantially as and for the purpose specified.

2. In combination, the yoke'A, wheels 0, hinged to the yoke A, draft-plates D, plowgangs E, bars F and H, said bar H rigidly connected with the bar F, springs I, and pivoted pole J, substantially as and for the purpose specified. p

3. In combination with the yoke A, formed of two parts, a a, and the wheels and draftplates hinged thereto, the bar F, and pole J, hinged to the bar F, and its rear end supported between the bars a a, substantially as and for the purpose specified.

In testimony whereof I affix my signature in presence of two witnesses.

GILPIN MOORE. Witnesses:

EUGENE LEWIS, L. B. KUHN.
