" Specification of Letters Patent. Patented Aug. 31, 132 1),

Application filed April 29, 1920. Serial No. 377,649.

This invention relates to improvements in cultivators, and more particularly to hand operated cultlvators ofthe wheel type,

an object of the invention being to provide improved means for connecting the standards and braces of the structure to the frame supporting the same, whereby the parts may be easily and quickly adjusted or re-arranged to perform the desired functions.

A further object is to provide an improved cultivator which is adapted to be pulled or pushed over the ground, which can be conveniently transported from place to place, and which will most efiiciently perform the functions for which it is intended.

A further object is to improve upon the construction. illustrated in my prior application filed November 29, 1919, and given S'erial No. 3 11,3533. V H

With these and other objects in view the invention consists in certain .novel features of construction and combinations and ar-j rangements of parts, asv willbe more fully hereinafter described'andpointed the claims. 7

In the accompanying drawing's v Figure 1 is a view in longitudinal section on the line 1-1 of Fig. 2, illustrating the position of parts when thedevice is to be pulled over the ground.

Fig. 2 is a top plan view of Fig. 1.

Fig. 3 is a view in longitudinal section on the line '33 of Fig; 4:, showing the "cultivator in position for pushing and also showing a modified arrangement of parts.

Fig. 4; is a top plan view of Fig.3. Fig. 5 is a view in section on the line 55 of Fig. 6, showing the parts inposition for movement from place to place.

' Fig. 6 is a top. planview of Fig. 5. r

Fig. 7 is a fragmentary perspective view illustrating the. manner of supporting one end of the transverse frame bars and the 7 connection. of the brace therewith.

Fig. 8 is an enlarged fragmentary View in. longitudinal section through the center of one of the standards.

Figs. 9 and 10 are fragmentary views in elevation at right angles to each other illustrating themanner of connecting one or the braces with the transverserod.

1, 1,'represent apairof wheels, preferably of relatively large diameter but light in weight. These wheels 1, 1, support an axle 2 and a pair of bracket arms 3, 3, have their forward ends bent forming sleeves 4L receiving the axle 2 andhence, pivotally mounted on theaxle. v

The bracket arms 3, 3, support a pair of bars 5 and 6. These bars 5 and 6 have trunnions 7. at their ends which are supported on the bracket arms 3, 3, and are held in position 011 the bracket arms by recessed bearing plates 8 positioned over the trunnions and secured by bolts 9 to the bracket arms 3. This construction and mounting of the bars 5 and 6 permits them to turn or pivot so that they can readily take any angular disposition desired in connectionwith my improved mounting for the standards 10 and braces 11, as will more fully hereinafter appear. 7 i

pair of handle bars 12 are employed and are connected at 1 their forward ends by a rubber covered handle 13. Therear ends ofthe bars 12 are connectedtothe axle 2 by means of co'llars 14 and 15. In other words, each bar is fixed to a collar 14: and, the collars 14; and 15 are connected byrectangular extensions 16, which constitute portions'of the handle bars and wliiclfextend normally I under the bracket arms 3, as

clearly shown in Figs. 1 and 2, so that by i imparting a pivotal movement to the handle, j tlie plows'can be raised and lowered and give thedesired elevation. The handle bars 12 are'preferably strengthened by a transverse brace rod 17 connecting them.

.The standards 10, above referred to, are

' at their upper portions in the'form of relatively flat bars havinga longitudinal series of slot's'18 therein. The bars 5 and 6 support a series of turn buttons 19, the shanks 20 of these turn'buttons having rotary is c mounting in the bars and the elongated I heads 21of said. buttons are of such a shape as to be projected throughv the, slots 18 and when turned at right angles. to the slots, will rigidly hold the'standards against the bars.

The lower portions of the standards have laterally and rearwardly projecting wings 22 which are recessed, as shown at .23, for the accommodation ofa tubular rod 24.

Each standard 10 is provided with a.

holding strip 25 pivotally connected to the wings 22 at its lower end as shown at 26, and adapted to be positioned across the rod 24 to hold the latter in the recess 23, or, in other words, couple the lower end of the standard to the rod. The upper end of this holding strip 25 is secured in place by means of a turn button 27, the shank 28 of which has rotarymounting in a rod 29 secured to the standard.

Vfhen the turn button 27 is inone position, the parts can be securely held, and when turned to its releasing position, the strip 25 canbe swung downwardly to disconnect the standard from the rod. Any suitable form of plow 30 may be connected to the lower end of the standard.

The standards 10 are removably connected to the rear transverse bar 6 and are strengthened by the braces 11 which connect the rod 2 with the transverse bar 5. These braces 11 are in the form of relatively flat strips or bars having a longitudinal series of slots 32 to receive in any of them the turn buttons 19 on bar 5.

The lower rear ends of the braces 11 are bowed or bent into U-shape, as shown at 33, particular reference being made to Figs. 9 and 10, and holding strips 34 are hingedly connected to the ends of the strip, as shown at 35, and are provided with slots 36 to receive turn buttons 37 on the braces to secure theniin position on the rod 24;.

It will thus be noted that I employ turn buttons to secure the standards to the bar 6, to secure the braces 11 to the bar 5, to secure the standards 10 and rod 24 together, and to couple the ends of the braces 11 to the rod 24. By reason of this construction, the parts can be easily and quickly connected and disconnected to form any desired assemblage and can be easily adjusted to give the proper angular disposition to the standards in accordance with the work to be done.

'In Figs. 1, 2, 5 and 6, I illustrate a single rod 24 extending. transversely of the cultivator, while in Figs. 3 and 4:, I illustrate a pair of these rods spaced apart at their center, and it is obvious that any desired arrangement of rods and standards can be employed according. to the work to be done by the cultivator. v

The parts are shown in Figs. 1 and 2 for pulling 'the cultivator over the ground. Figs. 3 and 4 illustrate the parts reversed when the cultivator is to be pushed over the ground, and Figs, 5 and 6 illustrate the bracket arms 3 and their connected parts thrown forwardly and supported on the handle bars so that the device can be conv veniently transported from place to place.

The pivotal -mounting of the bars 5 and 6 enables such bars to take any desired angular position so that'the standards and the braces can be connected or assembled in any desired manner without bending either of said parts, and hence, this feature enables an easy adjustment and control of angular disposition of'the standard and brace, as may be desired.

Various slight changes might be made in.

the generalform and arrangement of parts described without departing from the 1nvention, and hence I do not limit myself to the precise details set forth, but consider curing the standards to the bar, and braces connecting the lower portions of the standards with the forward bar.
