COMBINED HARROW AND CULTIVATOR.

I SPECIFICATION forming part of Letters Patent No. 469,123, dated February 16, 1892.

Application filed March 25, 1891.

To all. whom, it may concern;

Be it known that I, JOHN C. BURRUss, of Shreveport, in the parish of Caddo and State of Louisiana, have invented a certain new and useful Improvement in a Combined Harrow and Cultivator, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

This is a device which has hooked teeth arranged to be swung back and upward by any immovable obstacle and to be righted by the force of the horse in drawing the implement forward. The features of novelty will be set forth in the claims.

Figure I is a top view of the implement. Fig. II is a side view of the implement. Fig. III is a perspective view of one of the teeth. Fig. 1V is a transverse section taken at IV IV, Fig. I. Fig. V is a transverse section taken at V V, Fig. I. Fig. VI is a side view of the draft-bar. Fig. VII is a detail transverse section showing a modification in which a wooden cross-bar is used.

The draft-bar 1 has three bolt- holes 1, 1 and 1 The hole 1 receives the bolt of the draft-clevis, the hole 1 the pivot-bolt 2, by which it is connected atits inner end to the intermediate tooth-section 3 and the front side tooth-sections 4. The form of the intermediate tooth-section is shown in Fig. II more particularly by the broken lines, which indicate it in raised position. This tooth-section has a bolt-hole 3, through which passes a bolt 5 when the tooth-section 3 is in its lower position, as shown in full lines in Fig. II, the bolt also passing through the hole 1 and serving to hold the tooth-section rigid with the draftbar. Even in this case the tooth is capable of lifting to pass overa fixed obstruction, the front end of the draft-bar descending as the tooth-section goes upward.

In using the implement as a cultivator the tooth-section 3 may be fixed up in the position shown by broken lines in Fig. II, so that a row may be straddled. When used as a harrow or between rows, the tooth-section 3 is in its lower position. Each of the side toothseotions 4 has two bolt-holes, one 4 at its front end and'the other 4 at the rear end of its shank 4.

6 are pivot bolts or rivets by which these Serial No. 386,322. 1 (No model.)

sections are pivoted together, each bolt passing through the hole 4 of one section and the hole 4 of the section behind it.

7 are washers-beneath the heads of the rivets or heads and nuts of the bolts to lessen the wear upon the heads.

Each section 4 just behind the pivot has an outward bend or offset 4, taking itout of contact with the rear part of the section in front, so that there will not be liability of weeds to lodge between the sections at that point. The front side sections 4 4 are in clinedoutward from their point of connection with the draft-bar, so as to give the following sections a direction widening to the rear end of the implement.

It will be understood that the pivot-bolts are not made so tight as to prevent the free movement of the hinges as the teeth pass over an obstruction and are drawn down again by the draft-strain on the implement.

The sides are braced by two transverse frames shown, respectively, in Figs. IV and V. The front frame 8 has two bars 8 8", connected to the side bars by lugs 9 and bolts 10. The lugs 9 of the upper bar 8 are outside the shanks 4 and the lugs 9 of the lower bar 8 are inside the shanks, the bolts or rivets 10 passing through both lugs and the shank.

The straps 11 on the fore ends of the handles 12 are secured to the latter by bolts 11 and pass between the bars 8 8", and are held in position by bolts or rivets 13, passingthrough the bars and the straps.

The rear frame 14 has a bar 14 extending from shank to shank of the rear tooth-sections and connected to them by downturned lugs 14", which are upon the inside of the shanks, and bolts or rivets 15, passing through lugs 14 upon the braces 14. Said lugs 14 being outside the shanks, the braces are fastened to the bar 14 by rivets 15.

14 is an upright frame secured to the bar 14 at its feet 14 by means of rivets 14 and having a cross-bar at top extending from side to side of the handles 12. The sides of the bolts to a wooden truss, instead of forming a part of the metal bars.

I claim as my invention 1. The combination of the side tooth-sections having oifsets, bolts by which the side sections are pivoted by their middle portions and offsets to the adjacent side sections, suitable cross-frames, the draft-bar, and means by which the draft-bar is pivoted to the front side sections, substantially as described.

2. The combination of the draft-bar, the side tooth-sections, the front cross-frame, the rear cross-frame consisting of the lower bar and brace-bars having pendent lugs embracing shanks of the side sections and the upright bar having feet secured to the lower bar, and the handles 12, secured between the bracebars and the upright bar and to the front cross-frame, substantially as described.

3. "The combination of the draft-bar, the side tooth-sections, the front cross-frame having upper and lower bars formed with pendent lugs, the rear cross-frame having lower bar and brace-bars formed with pendent lugs and the Vertical bar formed with feet, and the handles secured between the brace-bars and the upright bar, having straps 11 secured between the bars of the front cross-frame, substantially as described.
