Application filed January 16, 1905. Serial No. 241,201.

To all whom it may concern:

Be it known that I, ELIAS HAIMAN, acitizen of the United States, residing at Cleveland, in the county of (Juyahoga and State of Ohio, have invented certain new and useful Improvements in Cultivators; and I do declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same. Y

My invention relates to improvements in cultivators; andthe invention consists in the construction, combination, and arrangement of parts thereof all substantially as shown and described, and particularly pointed out in the claims. I

In the accompanying drawings, Figure 1 is a perspective view of a cultivator comprising thereof.

my improvements, and the remaining figures are enlarged views of details and sections Fig. 2isa side elevation of a section of the central'bar or beam with my improved mechanism shown thereon in elevation. Fig. '3 is a plan view of 'Fig. 2,and Fig. 4 is aperspective view of. the two parts of my improved attachment seen together in Figs. 2 and 3 and separated to disclose the details of their construction. FigsI 5 and 6 are end elevations of Fig. 2; and Fig. 7' is a crosssection corresponding to line a: aflFig. 2, looking to the right.

The idea of the invention as thus disclosed in the several views is to obtain a positive and convenient adjustment of the side bars of the cultivator in respect to the central bar according to the width to be covered at any given time, the said mechanism b'eing within easy reach through a suitable lever whereby the operator can in a moment.

adjust the side bars to any desired width within the range of adjustment provided for and when adj ustmentis efiected rigidly fix the said bars in that relation, all as will'more clearly.

appear in the details of description.

Iam aware, of course, that'various devices have been made and used having the same gen eral object in view and that numerous patents struction is that it is exceedingly simple in itself and economical in manufacture and especially efiective and advantageous in use aml that sofar as I know and believe it is essentially new.

Referring again to the drawings, A represents the central tooth-bar of the. cultivator, and C the respective side bars thereof. These bars are equipped with cultivator-teeth a all around, which may be rigid with said bars or have standards C of their own pivoted and adjustable upon said bars to give more or less pitch to theteeth, as may be desired, and

either an integral or a pivoted construction may be used.

otally'engaged upon box B, and the two are adapted to slide together on bar A to effect the various adjustments of the side bars.

The box B is formed with right angled flanges d and d along its upper and lower edges, adapted to lap over the edges and side of bar A, top and bottom, and to confine the said section B upon said bar independently of the pivoted part D. In this sense, therefore, th-ebox B is an independent member remaining permanently in a slidable position on bar A, and it can be conveniently placed upon said bar, over the rear end thereof, before the rear cultivator-standard O is placed thereon. The

side bars O are connected with this box by upper and lower links 2 and 3, respectively, which I ver G,' whereby the position of the box is .con-

trolled. The pivoted side wing or looking member D is provided with short hinge-arms 6, having right-angled pivot-points 7 adapted to engage in the sockets or bearings 8 in the top ofsection B above and over the beam A in this instance, and the said arms are presumably engaged -in thesesockets before the parts are assembled upon bar A, so as to be permanently confined therein. .These arms tion.

andtheir pivot-points 7 in said sockets afford a free lateral rotation or swinging movement to the part D, so that it'may be rotated or turned away from the bar A to disengage therefrom when adjustment is to be effected and which will automatically spring or drop back against said bar again when adjustment has been made and the box is to be locked in working position. To these ends the said pivoted locking member D is provided with a series of holes 9 or their equivalent between its ends at suitableintervals apart, which are adapted to engage with the pin, projection,

or lug 10 on the side of bar A. Preferably this lug or pin is made a separate part fixed in bar A; but it might be formed in or from the bar itself and is treated herein as a part of the bar. Said pin has a tapered body set into a correspondingly-tapered seat and is upset on its opposite end to fasten it in the bar, which makes a convenient method of manufacture and a desirable locking projection for the box. The said pivoted part D is designed normally to rest against the side of bar A in a locked position by engaging one of its holes over lug or pin 10, and it is held in such position by a spring 12, which is confined between corresponding lateral projections 18 and 14: on the two parts B and D. This spring comes on the opposite side from the pivoted locking member or wing D and the pivots thereof on the side of box B, so that its tendency is to hold part D in locked position, and adjustment can only be effected when the said part or member D has been carried or swung laterally upon .its pivots a suflicient distance to disengage it from pin 10. This is accomplished by means of a crank-lever g at the top of main lever G, which is connected by a wire or its equivalent g with the lateral projection 15 at. the top and edge of the said member or wing D. When such disengagement is effected by these or equivalent means, the .box as a whole, with wing D, may be moved along by lever Gr upon the beam A back or forth, as may be required, and when lever g is released and part D drops back to engaging position it is easy to move it into connection with the nearest hole 9 upon the lug 10, if this has not already occurred, and thislocks the parts again in working posi- Any suitable means may be provided as a fulcrum for lever G; but in this instance a link 16, connected'with the cross-bar 17 on the handle-supporting braces 18, serve as such fulcrum.

It will be noticed that the bearings 8 for pivot or hinge projections 7 are raised portions in the overhanging upper right-angled edge cl of the box B and that engagement with said bearings or sockets can only be made from beneath before the box is placed on the central bar, and when on both parts B and D are permanently engaged on said bar. It will also be noticed that the said locking member D has only such width that it will come be tween the edges d and d of box B, and the said box has therefore an open side to receive the said member D and which enables it to slide without contacting with projection 10.

Obviously the openings or holes in the locking member D might extend to the bottom edge thereof, which would give it the appearance of a rack-bar; but this would be equivalent only to what is shown, and said member or part D might be as much shorter as a more limited range of adjustment would suggest.

YVhat I claim is- 1. In cultivators, a central and side bar, a slidable member on the central bar and a locking device pivoted thereon, said central bar provided with a projection at its side to engage said locking device therewith, a controlling-lever for said slidable member and means thereon operatively connected with said locking device to release the same from locking engagement.

2. In cultivators, a central bar having a fixed lateral projection at its side, side bars and meansto fix the working position of the side bars in respect to the central bar comprising a device slidable on the central bar, links conmeeting said device with the said side bars and a lock for said device pivoted thereon and constructed to engage adjustably with the said lateral projection on the central bar.

3. In cultivators, central and side bars and means to adjustably fix the relations of the side bars comprising a box slidable on the central bar and links connecting said box with the side bars, said central bar having a lateral projection at its side, and a lock for said box. provided with a series of openings adapted to engage with said projection.

4.. Acultivator having central and sidebars, means for controlling the position of side bars consisting of a box on the central beam having an open side lengthwise, a locking device for said box in said open side and the said central bar constructed at'its side to engage said locking device.
