Lette/rs'late'nt No. 87,101, dated February 23, 1 y 69.
The Schedule referred to these Letters Patent and making part of the lame.
To all whom it may concern;
Be it known that I, J AMES HARRIS, of the city of Janesville, in the county of Rock, and State of Wisconsin, have invented certain new and useful Improvements in Onltivators and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanyin g drawings. mak: ing a part of this specification, in which- Figure lis a side view or elevation of the dragbarand tooth or shovel of .a cnltivator, as I construct them, Aand as they appear when in use;
Figure 2 is also a side view or elevation of the same as they appear when the cultivator is backing;
Figure 3 is a longitudinal vertical section of the same as they appear when the tooth has been released by coming in contact with an obstruction; and
Figure 4 is a top view of a -portion of two drag-bars, showing their position in connection with the draughtrod.
The nature of my invention relates to the teeth and drag-bars of cnltivators, and consists- First, in connecting the shank of the tooth to an independent circle-iron, when constructed and used in connection with the drag-bar, substantially as and for the purpose hereinafter described.
Second, in joining the drag-bar to the draughtrod, by means of an elongated metallic box-bearing, substantially as and for the purpose hereinafter described.
To enable others skilled in the art to make and use my invention, I will proceed to describe its construction and operation.
In the drawings- A represents a drag-bar, of wood, or other suitable material;
B, the tooth;
C, the circle-iron; and
D, the elongated metallic box joining the drag-bar A to the draught-rod K, fig. 4.
The tooth at the end of the shank, and the circleiron at its upper end, have a common bearing on the pivot-pin a that passes through the drag-bar.
The lower end ofthe circle-iron is joined to the shank This safety-coupling consists of a simple bolt passing through the shank, and also through a slot, c, in the circle-iron.
' On the end of the bolt is a washer, larger than the width of the slot, and a nut to clamp them together.
The nut may be in the circle-iron andthe slot in a flange or short ear on the shank, if desired, or a boltstaple in the shank, clasping around the circle-iron, and dispensing with the slot, may be used.
'Io set the teeth, or to give them the desired pitch,
or inclination, I pierce the circle-iron with a series of holes, d, through either of which the setting-device E may be secured.
This setting-device may consist ot' the -bolt and square-faced' lugs, as shown, or of the simple pin l, shown in iig; 3. In the latter case, the upper face of the drag-bar (if of wood) should be covered with a metallic plate, to prevent the pin from indenting the woo l.
The elongated box-bearing D should be of cast-iron, of the form shown, in which case the forward end of the drag-bar should be slotted to receive it, and the same secured therein by a bolt, f, passing through the flange h.
The box is bored or cast with orlnce e, so as to nicely fit on the draught-rod K, g. 4, and extends beyond the drag-bar, on either side, one-half of the Width of the space between the bars.
The positionfof the drag-bars on the draught-rod, and the oice of the elongated box-bearing, are shown in iig. 4. v
As heretofore joined to the draught-rod, it hasbeen impossible to keep the drag-bars (and teeth) in line, as, owing to their short bearing on the draught-rod, they were constantly swinging and swaying sidewise.
As heretofore constructed, it has been the custom, in order to keep the bars the proper distance apart, tc fill the space between them on thedraught-rodlwith washers.
To avoid the use of washers, and to keep them securely in line, by giving them a broad, firm bearing on the rod, I employ the elongated metallic box described.
It is not essential to my invention that the box D should be inserted in a slot in the drag-bar, as the same results may be accomplished by bolting it underneath or on the top of the bar, or by constructing it in sections and bolting them upon the sides thereof.
It will be seen that the adjustable settingedevice E secures without change, when once set, the pitch or inclination of the teeth, and allows them to swing forward, as shown in fig. 2, when the cultivator is backed.
It willalso be seen that the safety-coupling?) holds the teeth with an adjustable force, and when once the tooth is drawn back by an obstruction, the short distance necessary to withdraw the bolt from the slot c, the tooth is not still held by the coupling, but is entirely free; also, that the freeing or loosening of the tooth does not affectthe previous setting of l'its pitch or inclination, which remains unchanged, however often the tooth maybe loosened.
What I claim, is-
1. The detached or independent circle-iron O.
2. The arrangement of the detached circle-iron O withthe tooth B, whereby both have a common bearing on the pivot-pin a, substantially as described.
3. The combination of the tooth B,eiro1eiron (Land 6. Joining the drag-bars to the draught-rod by coupling-device b, substantially as described. means of the elongated metallic box D, whereby e 4. The arrangement-0f the tooth B, independent broad,1'm bearing is secured, and washers between circle-iron C, setting-device E, and drag-bar A, subthe bars dispensed withfsubsteutielly as described. stentiaily as and for the purpose described.
