COMBINED HARROW AND CULTIVATOR.

SPECIFICATION forming part of Letters Patent No. 440,450, dated November 11, 1890.

Application filed May 6, 1890- Serial No. 350,831. (No model.)

To all whom it may concern:

Be it known that I, FRED G. UMBACH, of Athens, in the county of Clarke and State of Georgia, have invented a new and Improved Combined Harrow and Cultivator, of which the following is a full, clear, and exact description.

My invention relates to an improved harrow and cultivator, and has for its object to provide a harrow of exceedingly simple and durable construction, to which, when desired, a cultivator-tooth may be attached, whereby the implement as drawn forward will perform the dual functions of a harrow and a cultivator.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures of reference indicate corresponding parts in all the views.

Figure 1 is a plan view of the implement. Fig. 2 is a side elevation thereof. Fig, 3 is a plan view of the harrow-frame detached from the shank, and Fig. 4 is a side elevation of one of the harrow-teeth removed from the frame.

In connection with the device an ordinary plow-beam 10 is employed, to the rear end of which the usual handles 11 are attached, the forward end of the beam being provided with a suitable clevis 12. The shank 13 is curved and bifurcated, and is adjustably attached to the beam 10 by means of bolts 13", passed through apertures 14, formed in the upper portion of the members of the shank, one bolt being usually located immediately above and the other immediately beneath the beam.

The harrow-frame 15 is made of one piece of metal bent to an angular shape, represent ing approximately two sides of an equilateral triangle. At the apex of the frame the metal is struck up or otherwise manipulated to form an arch 16, the upper member or face of which. is given a downward inclination in the direction of the front, as is best illustrated in Figs. 2 and 3.

In the upper face or member of the arch 16 an opening 17 is produced, and a series of threaded apertures 18 is formed in the frame at each side of the said arch, as is best illus trated in Fig. 3. The apertures 18 are adapted for the reception of the upper threaded ends of the harrow-teeth 19, one of which teeth is illustrated in detail in Fig. 4. The bodies of the teeth may be either circular, square, or polygonal in cross-section, and the lower ends of said teeth are sharpened or pointed.

It will be observed that by reason of this construction nuts need not be employed in connection with the teeth, as the said teeth will maintain their position in the frame by simply being screwed into the apertures thereof, as aforesaid.

If in practice it is found desirable, the sides of the frame may be connected at the rear of the arch 16 by means of a transverse bar 20, in which event the bar is also provided with threaded apertures for the reception of additional harrow teeth; but the bar 20 may be omitted, if so desired.

The under face of the arch of the harr0wframe is adapted to rest upon the lower front face of the shank 13 and upon the outerface of member of the said arch. The upper end of a cultivator-tooth 21 has a bearing, which cultivator tooth inclines downward in the di rection of the front, and the frame and tooth are secured to the shank through the medium of a single bolt and nut, as shown at 22 in Fig. 2, the bolt being passed through the tooth, the opening 17 in the arch of the frame, and through the lower end of the shank, the lower extremity of which bolt has screwed thereon a suitable nut.

From the foregoing description it will be observed that a combined harrow and cultivator is obtained of very simple construction and capable of accomplishing good work, and that if the cultivatontooth is not required it may be readily and conveniently detached; also, that in the event of any of the h.arrow teeth becoming broken or otherwise injured they may be removed and others substituted.

When a side harrow only is desired, one member of the harrow-frame 15 is dispensed with, and the frame is made to include only one side arm and the arch.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. The combination, with a shank or standbarrow-frame 15, formed of a single piece of metal and provided with the central arch 16,

the curved and bifurcated shank secured to 15 'the beam, the teeth 19, secured in apertures in the frame, and the cultivator-tooth secured to the arch by a bolt passing through the tooth, arch, and shank, substantially as herein shown and described.
