CULTIVATOR BEAM LIFT Filed April 17, 1929 2 Sheets-Sheet 2 In venior filz'ejere: 20 8 W A itorney a I Patented Feb. 24, 1931 UNITED STATES PATENT OFFICE .mxnnnannns, or HARRIS, IOWA cULnvA'roa-nnm LIFT Application filed April 17,

The present invention relates to an attachment for cultivators of the one or two row type and has for its prime object to provide means whereby theshovels may be raised simultaneously and equally in respect to the ground.

' It is the common practice to hingedly mount the frame in which the cultivator shovels are mounted so that when the frame is raised or lowered the front shovels dig at a different depth than the rear shovels but with my attachment this undesirable feature is overcome as all the shovels will always be at the same depth.

A still further important object of the invention resides in the provision of an improved structure of this nature which is simple, inexpensive to manufacture, capable of being incorporated in standard equipment, thoroughly efficient and reliable in use and operation, and otherwise well adapted to the purpose for which it is designed.

With the above and numerous other objects in view as will appear as the description proceeds, the invention resides in certain novel features of construction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.

In the drawing:

Figure 1 is a verticallongitudinal section through a cultivator showing my improved attachment mounted thereon,

Figure 2 is a horizontal section therethrough,

Figure 3 is a perspective view of a portion of the attachment, and

Figure 4 is a perspective view of the links used with the attachment.

one of Referring to the drawing in detail it will be seen that the numeral 5 denotes the tongue of a cultivator mounted on the arched axle 6 in the usual well known manner.

The numeral 7 denotes an inverted U- shaped hanger each leg of which is provided with a pair of journals 8 and 9 the latter spaced upwardly from the former. Numerals 10 denote standard frames in which are mounted in the usual Well known manner cultivator shovels 11. These frames 10 are provided with arms 12 adjacent their. for- 1929, Serial n. 355,737.

ward ends inclining upwardly and forwardly. i r l Bearing blocks 14 and15 are provided with horizontal bores to receive the journals 8 and 9 respectively and with vertical bores to receive. depending pintles 16 of links 17 having lateral pintles l8 journaled in the forward ends of the frame 10and the upper extremities of the arms 12. r

The numeral 19 denotes standard raising and lowering means for the cultivator frame. Braces 20 extend from the extremities of journals 8 to portions of theaxlc 6to prevent swinging of the inverted U-shaped hanger 7.

From the above detailed description it will be seen that whenthe frames 10 are raised or lowered they move so as to always be in a plane substantially parallel with the tongue 5 because ofthe parallelogram arrangement afforded .by the links 17 as will be readily appreciated and therefore the frontand rear shovels as well as the intermediate shovels will always digat the same depth.

It is thought that the construction, oper ation, and advantages of this invention will now be quite apparent to those skilled in this art without a more detailed description thereof. x

The present embodiment of the invention has been disclosed in considerable detail merely for the purposes of exemplification since in actual practice it attains the features of advantage enumerated as desirable in the statement of the invention and the above description.

It will be apparent that changes in the details of construction, and in the combination and arrangement of parts may be resorted to without departing from the spirit or scope of the invention as hereinafter claimed or sacrificing any of its advantages.

Having thus described my invention, what I claim as new is:

1. A cultivator of the class described comprising a tongue, an axle on which said tongue is supported, wheels on the axle, a pair of cultivator frames, a substantially inverted U-shaped hanger depending from the tongue forwardly of said cultivator frame,

said hanger including spaced parallel legs, the legs of said hanger adjacent their lower ends being each provided with a pair of journals one above the other, bearing blocks having horizontal bores to receive said journals, on said journals,

said bearing blocks being further provided with vertical fbores,

links connecting said bearing blocks on the lowermost journals with the forward end of said? cultivator frame, arms rising upwardly and.

, forwardly from the forward end of said cultivator frame, links connecting the-bearing blocks on the upper ournals with the upper forward end of said arms,'all of said links at one end thereof being provided with a vertically disposed pintle receivable in the vertical bore of the respective bearing block,

and the links connecting the lowermost bear-V ing blocks with the forward end of said cultivator frame having laterally disposed pintles journaledinthe forward end of said culti-' vator frame, and the links connecting the upper bearing blocks with said arms having at their other ends laterally extending pintles journaled in the upper forwardend of'said arm, said links being arranged in parallelism, and means for connecting the frame forretainingthe latter always in a plane substantially with said tongue during the raising and lowering of said frame.

2. A' cultivator comprising in combination a tongue, an earth working implement sup 7 ortin frame ahan 'er de oendin from said tongue, said hanger including a vertically disposed le an arm pro ectlng upwardly and forwardly from said frame, said leg adjacent its lower end provided with a pair of upper and lower vertically spaced lateral journals, bearing blocks on said journals, said bearing blocks provided with vertical bores, a pair of links, said. links at one end provided with depending pintles' receivable in said bores, said links at their opposite ends provided with lateral pintles, and the lateral pintle of one of said links engaging the free end of said arm, and the lateral pintle of the other of said links engaging the forward end of said frame.

V In testimony whereof I affix my signature.
