CULTIVATO R.

SPECIFICATION forming part of Letters Patent No. 334,327, dated January 12, 1886.

Application filed September 4, 1885. Serial No. 176,186.

To all whom it may concern:

Be it known that I, SAMUEL L. ALLEN, a citizen of the United States, and a resident of Oinnaminson, Burlington county, State of New Jersey, have invented certain new and useful Improvements in Cultivators, of which the following isa specification.

My invention relates to certain improve ments in cultivators, the object of which is to produce an improved device for connecting the standards which carry the mold-boards to the frame so that the standards may be readily adjusted in position.

I have already, in Letters Patent of the United States No. 281,426, granted to me July 17, 1883, shown and described a device for connecting the standards or arms which carry the share-like blades to the frame.

In my former patent I have shown a standard or arm made of struck-up steel, and having a rounded head bounded by a flange, on the upper edge of which are aseries of notches, into any one of which a locking projection or retainer connected to the frame was made to fit. I By using the device herein shown I am enabled to dispense with a retainer on the side bar of the cultivator for entering a notch on the upper edge of the rounded head of the arm or standard.

In the accompanying drawings, Figure 1 is a perspective view of the device. Figs. 2, 3, and 4 show,respectively, obvious substitutions in connecting the boltO to the side bar, A. Fig. 5 shows a front elevation of the bolt 0. Fig. 6 is a bottom View of the flanged head E of the standard, showing the position and arrangement of the teeth or notches which are engaged by the locking device F. Fig. 7 is a front elevation of the block D. Fig. 8 isa' plan view of the teeth F of the bolt 0. Fig. 9 is a top view,partly in section,of the block D. Fig. 10 is asectional view of the side bar, A, and stay-bar B, showing how the side bar, A, is constructed when cut away as in Fig. 2 and connected by the bolt 0, broken oil.

A is the sidebar of the cultivator; B, the

- stay-bar, which holds the head Eat a fixed distance from the central bar of the machine. G is a duplex bolt, provided with one or more teeth, and serves the double purpose of attaching the standard to the frame of the cul- (No model.)

tivator and also by the teeth at the point F of locking the standard in any position in which it is fixed.

D is a block, which I preferably use as a means for holding one end of the duplex bolt 0, and also to position the head of the standard, although the block D can be obviously dispensed with, as shown in Figs. 2 and 3.

One arm of the duplex bolt Opasses through the central hole of the head of the standard, andforms the axis of the standard, thence through the stay-bar B and the side bar, A, where it is clamped by the nut G. The other arm passes through the block D, which is firmly riveted to the bar A.

I have shown a device in Fig 2 which, while it is an obvious substitution ofthat shown in Fig. l, I am yet enabled to use a side bar as light as that shown in Fig. 1, and dispense with the block. The end of the bar is simply wedged or forged into the form ofa double eye, as shown, and one arm of the duplex bolt passes through each eye.

In Fig. 3 is shown an obvious substi'zuticn from Fig. 2, wherein,instead of a clip, block, or eye. Thebolt is passed through the sidebar itself. This, however, requires an increased thickness in the bar A.

In Fig. 4 I have shown an obvious substitution for the clip or block D shown in Fig. 1.

In the devices shown in Figs. 2and 3,where I do not use the clip or block D, it will be noticed that the end of the bar A is cut away at M to an amount equal to the thickness of the stay-bar B,which allows the side bar,A,to rest readily against the head E when all the parts are in place. This is illustrated in the sectional view in Fig. 5. V

I preferably make the standard provided with the flanged head, as described,ofstrucl:- up sheet-steel, as it can be rapidly made with suitable dies and a drop-press. The bolt 0, provided with the teeth F, can also be easily and rapidly formed from rods by means of dies and press.

When the nuts of the legs of the bolt 0 are loosened, the standard can be turned on the leg of the bolt, passing through the stay-bar as an axis, and so placed at any desired angle with reference to the line of draft. \Vhen the standard has been placed in the proper position,it is simply necessary to tighten the nuts of the bolt 0, and the teeth F are brought into connection with the notches E on the under side of the flanged head of the standard, by which means it is firmly held in position for work.

Among the many advantages of my improved device may be mentioned simplicity, both in the manufacture and use of the parts, and strength, and durability in action.

Having now fully described my invention, what I claim is 1. The combination of a standard having a notched head, E, with a side bar,A, and with teeth F, the side bar, A, and stay-bar B, sub- 20 stantially as described.

In witness whereof I have hereunto set my hand.

SAML. L. ALLEN.
