WILLIAM H. TRACY, OF HOLLAND, KENTUCKY.

COMBINED CLOD-CRUSHEB AND SCRUB-GUTTER.

Application filed August 31, 1916.

To all whom it may concern:

Be it known that 1, WILLIAM H. TRACY, a citizen of the United States, residing at Holland, in the county of Allen, State of Kentucky, have invented a new and useful Combined Clod-Crusher and Scrub-Cutter; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same This invention relates to a combined clod crusher and scrub cutter, and one of the objects of the invention is to provide a device of this kind which is simple, etficient and practical in construction.

Another object of the invention is to provide a device of this kind consisting of a frame constructed in two sections hingedly united, the rear section of which has a plurality of clod or scrub cutters, and is adapted to be thrown upon the forward section, to hold the scrub cutters out of operation.

Another object of the invention is to provide yieldable supporting means forithe rear section, when folded upon the forward section.

Another object of the invention is to provide a plurality of bars pivoted transversely of the rear section, each carrying a series of clod and scrub cutters, each of which bars is adapted to be inverted, so as to hold the cutters out of operation, either when the rear section is folded or is thrown down to drag at the rear of the forward section.

In practical fields the details of construction may necessitate alterations falling within the scope of what is claimed.

The invention comprises further features and combination of parts as hereinafter set forth shown in the drawings and claimed.

In the drawings 1-- Figure 1 is a view in perspective of the improved clod crusher and scrub cutter con structed in accordance with the invention.

Fig. 2 is a longitudinal sectional view on line 22 of Fig. 1.

Fig. 8 is a sectional view showing the rear section folded.

Fig. A is a sectional View on line 44: of Fig. 2.

Fig. 5 is a sectional view on line 55 of Fig.

Referring more especially to the drawings 1 designates the frame as a whole of the improved clod crusher or scrub cutter, which Specification of Letters Patent.

frame consists of the forward and rear sections 2 and 3, which are hingedly united by means of the transverse rod 5 and the eyes 6 of the plates 7 which are secured at 8 to the sections. The sections consist of the side runner members 9 and 10. The sides 9 are connected by the transverse bars 11, the ends of which are counter-sunken in the sides 9, there being angled bars 12 for holding the bars 11 to the sides. Connecting the bars 11 is a central bar 13. The bars 11 are countersunken into the under face of the bar 13, while the bar 18 is countersunken in the upper faces of the bars 11, there being suitable bolts 1 1 connecting said bars. The bar 13 is additionally braced relative to the forward bar 11, by means of the angle bar 15. A suitable equalizer (not shown) may be connected to the forward extremity of the bar 13 whereby the machine may be drawn over the soil. Secured upon the under portions of the sides 9 are the runner plates 16. Referring to the rear section it is to be seen that transverse bars 17 have their ends countersunken in the upper edges of the sides 10, there being metal straps 18 bolted to the bars 17 and the sides 10 to insure a rigid structure. Connecting the bars 17 and countersunken therein is a central bar 19. A bolt 20 extends through the rear end of the bar 19 and the rear transverse bar 1'? thereby connecting the two bars. Secured by a bolt 21 and a bolt 22 is a supporting spring mem- 381 23, which is carried by the bar 19, so that the spring arm 24 will engage the bar 13 when the rear section is folded in an inverted position upon the forward section, thereby holding the cutters or their carrying bars out of engagement with the ground. The bolt 22 passes through the forward bar 17, and the central bar 19, thereby additionally reinforcing the structure. Bolted to the rear upper surfaces of the sides 10 are handle.

members 25, whereby the operator may fold the rear section upon the forward section. Arranged from one side 9 to the opposite side 9 are three bars 26, which in cross section, as shown in the drawings are disposed angularly. Secured upon the front faces of the bars 26 at their end are angular plates or straps 27, which are bolted at 28 to the adjacent faces of the sides 9. In the rear of the bars 26 are abutment plates 29, which are carried by the inner adjacent faces of the sides 9, to reinforce the bars 26. Wear plates 30 are bolted upon the bars 26, with which the clods and the like contact, thereby preventing wear upon the bars. The plates are angular in cross section, so as to fit the corners adjacent the under edges of said bars 26. Arranged transversely of the rear section are the transverse bars 31, the opposite ends of which are provided with angular straps or plates 32, which are pivoted upon bolts 33 to the inner faces of the sides 10, whereby the bars 31 may be arranged in different adjusted positions pivotally, so that the bars 31 may be disposed as shown in Fig. 2 in contact with the abutment plates '34-, which are carried by the inner faces of the sides 10. It is to be seen that the bars 31, each carry a series of cutting knives 35. Each knife consists of a single piece or strip of metal twisted upon itself as shown and bolted at 36 to the bar. It is to be seen that when the bars 31 are disposed as shown in Fig. 2, the knives are arranged in a rearward direction, so as to bury deep into the soil, for cutting and chopping the clods and the like. However, when the rear section is thrown down, in order to drag at the rear of the forward section, as shown in Fig. 2, the bars 31 may be moved upon their pivots, so as to dispose the cutting knives in an upward and forward direction, and out of operation, whereby the bars 31 may drag on the soil. This particular manner of disposing the bars 31 is particularly used when the rear section is folded in an inverted position upon the forward section, thereby holding the knives in suchwise as to prevent injury to the hands of the operator. Secared to the outer faces of the sides 9 are hinges 37, the pivoted leaves of which have slots 38, to receive the staples 39 of the outer faces of the sides 10, there being hooks l0 rear section may be folded upon the forward section and a spring support carried by the upper face of the rear section to engage the forward section, to support the rear section when folded, and of means for latching the two sections, whereby the rear section may drag rigidly .in the rear of the forward section, a plurality of drag bars connecting the sides of each section.

2. In a clod crusher and scrub cutting machine, the combination of a frame consisting of two sections hingedly united, whereby the rear section may be folded upon the forward section and a spring support carried by the upper face of the rear section to engage the forward section, to support the rear section when folded, of means for latching the two sections, whereby the rear section may drag rigidly in the rear of the forward section, a plurality of scraper bars connecting the sides of each section, means for pivoting the scraper bars of the rear section, abutment means for the pivoted scraper bars, and knives carried by said pivoted scraper bars.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses. 7
