SPECIFICATION forming part of Letters Patent No. 616,961, dated January 3, 1899.

Application filed January 21, 1898. Serial No. 667,512. (No model.)

To all whom it may concern.-

Be it known that 1, JAMES H. PATTEE, a citizen of the United States, residing at Monmouth, in the county of 'Warren and State of Illinois, have invented certain new and use ful Improvements in Cultivators, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to'improvements in V cultivators, and is shown applied to a walk in g straddle-row machine. It has for its leading object the production of improved mechanism to aid in lifting and holding elevated the plow beams and shovels attached thereto, the same consisting of devices which properly counterbalance the weight of such beams and shovels in any position. Y

Another object of my invention is the provision of means whereby the shovels carried by the beams can be independently and quickly adjusted so as to run at any desired depth in the soil.

These objects I accomplish by the devices and combinations of devices shown in the drawings and hereinafter fully described.

That which I regard as new will be pointed out in the claims.

In the accompanying drawings, Figure 1 is a side elevation, one of the wheels being removed and the axle being shown in section. Fig. 2 is a detail of the counterbalancing devices in the position they assume when the shovel-beam is raised, the position of. the shovel-beam being indicated by dotted lines. Fig. 3 is a detail, being a cross-section at line 3 3 of Fig. 1. Fig. at is a detail of a portion of a shovel-beam, showing my improved device for regulating the depth of cut of the shovel attached to its lower end; and Fig. 5 is an enlarged detail of the device for regulating the depth of cut of the shovel.

Like letters of reference indicate like parts in the several figures.

Referring to the several figures of the drawings, A represents one of the wheels of the machine, the companion wheel not being shown, that the improvements may by more clearly disclosed.

B represents an arched axle upon which is mounted a tongue 0, suitably braced by braces a, as usual. At the rear of the tongue are the ordinary hang-up hooks b.

D is a pipe-box upon each horizontal end of the axle B, upon which is suitably secured a collar 0, having rearwardly-extending arms 61 for receiving the bolt 6, that unites the yoke E at the forward endof the beam F to the pipe-box.

f indicates the usual eye on the upper side of the beam for suspending such beam to the hook I) at the end of the tongue.

9 indicates the beam -handle, and h the shovel-standards, either made integral with the beam or secured thereto, as shown.

The parts so far referred to are of ordinary construction and therefore need no further description.

Referring now to the counterbalancingmechanism, G represents a bent lever at the inner end of the pipe-box D and formed with or secured to such pipe-box. Secured to the forward and upper end of the bent lever G by a suitable pivot is a bar or rod II.

I represents a plate secured to one of the vertical portions of the arched axle B by a clip m, upon the ends of which are loosely mounted two cogged segments '5 and i, the teeth of which mesh with each other, as shown. Each cogged segment has a lateral extension 7c is, respectively, and to the extension 7c is pivoted the upper end of the bar or rod H.

J represents a coiled spring, the upper end of which is attached in any suitable manner to the extension and is attached at its lower end to a hook Z on the end of the lower and backwardly projecting portion of the bent lever G. Any suitable means 'may be employed for regulating the tension or pull of this spring.

The construction and arrangement of the parts, as above described, provide a perfect counterbalance at all times for the beam and its attached shovels, enabling the operator to raise or lower such beam with but slight effort. It will be understood that when the beam is in the position shown in Fig. 1 the spring J is extended and is pulling up on the backwardlyrojecting portion of the bent lever G and pulling downward on the cogged segment 'i. In consequence of its teeth meshtion shown in Fig. 2

ing with the teeth of the similar segment 2" it causes the same force to push down on the bar or rod II, and in this position it will be seen that the lower end of the bar or rod H is back of the pivotal point of the bent lever G and the downward force of the bar or rod H is in an opposite direction from the upward force of the spring J. Consequently one offsets the other and leaves the cultivatorshovels free to take the ground. It will be understood that in raising the beam from the position shown in Fig. l to the hang-up posithe bent lever G will turn with the pipe box D, to which it is secured, thereby throwing the upper end of the bent lever G forward and downward and causing the downward force of the bar or rod II to work in unison with the upward force of the spring on the other end of the bent lever G. \Vhen the shovels are in the ground, the spring when adjusted properlyin place works on practically a dead-center and is perfectly neutral in its action; but immediately the beam is swung upward a sufficient lifting force to balance the beam and attached shovels is exerted, the leverage growing greater as the spring shortens, so that an almost perfect balance is maintained until the eyefis placed over the hang-up hook b.

The device is shown and described as applied to one side of the cultivator only; but it will of course be understood that each side of the machine is equipped alike.

I have termed the part G a bent lever as a convenient single name for the two projecting parts, although they may be two independent lugs or projections extending out from the pipe-box.

Referring now to the second-stated object of my inventionviz., the means for adjusting the cultivator-shovels to diiferent positions to suit the depth that it is desired to have them penetrate the soil-K indicates a sleeve (see Figs. 4 and 5) secured to the tube or bar at the end of the shovel-standards, to which sleeve the shovels are adapted to be secured by clam p-sockets h, having set-screws 71 The sockets are constructed so that they can slip over the lower ends of the sleeves K and be rigidly secu red thereto in any adjusted position through the medium of the setscrews 7L2. The upper end of the sleeve K, where it goes over the said tube or bar on the shovel-standard, is slightly enlarged, as shown, and in such enlarged portion is a longitudinal slot '12. At the upper end, at each side of said slot 91, are cars 0, through holes in which is passed a bolt L, on the end of which is a nut 17. After the sleeve is adjusted in place it is secured by tightening up this nut 19, the effect of which is to draw the sleeve tightly against the tube or bar referred to, this being permitted by reason of the slot at, as will be understood. In many instances such an attachment will be found very usefulas,for example, in cultivatinglisted corn it is frequently desirable to have the inside shovels run from three to four inches below the outside ones, thereby permitting them to reach the level of the plant. Again, the sleeve can be used on the outside beams alone when it is desired that the outside shovels run the deepest, as in the case of bedded cotton. When it is not desired to use the sleeve, it can be very readily detached and the shovels applied as usual, as shown in Fig. 1.

That which I claim as my invention, and desire to secure by Letters Patent, is-

V 1. In a cultivator having an arched axle, the combination with a pipe-box on the wheel portion of said axle, of a shovel-beam connected with said pipe-box, a bent lever on said pipe-box, a rod extending upward from one arm of said lever, a spring secured to the other arm thereof, and two intermeshin g cogged pieces pivoted in place on the arched portion of the axle and connected respectively to the said rod and spring, substantially as and for the purpose specified.

2. In a cultivator having an arched axle, the combination with a pipe-box on the wheel portion of said axle, of a shovel-beam c011- nected with said pipe-box, a bent lever on said pi pe-box, a rod and a spring connected to different portions of said bent lever and connected with each other at their upper ends through a pair of intermeshing cogged pieces, substantially as and for the purpose specified.

3. The combination with a shovel-stand ard, of a sleeve constructed at one end with a longitudinal slot and two laterally-projecting ears, the slotted end of the sleeve being constructed to fit the end of the shovel-standard, a bolt passing through said ears to clamp the sleeve in position, and a cultivator-shovel having a clamp-socket constructed to be adjusted longitudinally along said sleeve when the latter is secured to the shovel-standard, and means for securing the clam p-socket on the sleeve in the desired position of adjustment, the clamp-socket also bein g constructed to fit the shovel-standard when the sleeve is removed, substantially as and for the purpose specified.
