HARROW.

SPECIFICATION forming part of Letters Fatent No. 640,523, dated. January 2, 1900.

Application tiled July 15,1899.

To @ZZ 2071/072?, zit may concern:

Be it known that LWILLtnM M. BAKER, of Fortville, in the county of Hancock and State of Indiana,have invented a new and Improved Harrow, of which the following is a full, clear, and exact description.

The object of my invention is to so improve upon the construction ofthe harrow for which Letters Patent were granted to me April 25, 189D, No. 623,75), that the machine can be quickly adapted for work in trashy ground.

Another object of the invention is to provide a simple device which will not only remove trash from the toothed roller of a harrow, but will ett'ectually conduct the trash to the rear of the machine, and, furthermore, to so construct the cleaning device that it will also pulverize the ground taken up by the teeth of the roller.

rllhe invention consists in the novel con struction 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 characters of reference indicate correspon ding parts in all the figures.

Figure 1 is a partial plan View and horizontal section of a machine to which the improvement is applied. Fig. 2 is a side elevation of a machine with the improvement applied thereto, a part of the rear portion of the frame being broken away. Fig. 3 is a side elevation of a machine to which the improvement is particularly adapted, illustrating the machine as now used; and Figa is a longitudinal vertical section through a series of the cleaners and a portion of the devices employed for supporting the cleaners.

The improved device consists of a blade A, made of steel or other stiff sheet material. At the front central portion of the blade a downwardly-curved hook cr bill 10 is formed. and the upper part of the front portion 11 of the blade is curved upwardly and rearwardly from the top of said hook or bill, while the lower front portion 12 of the blade is inclined downwardly to meet a lower straight edge 13, while the upper inclined edge 11 meets an upper straight edge 14E. A projection 15 is Serial No. 728,902. (No model.)

and a notch 1G is made in the upper edge of this projection adapted to receive the rear beam of a harrow-fraine or the equivalent of the said beam.

The blades A are arranged in series at suitable distances apart upon an angular shaft 17, as shown in Figs. 1 and 4, being spaced by washers 18, and each blade has an opening at or near its center, through which the 6o said shaft 17 is passed. The ends of the shaft 17 are rigidly held in standards 19, adapted for attachment to the frame of the harrow, the blades being below the under surface of the frame.

The blades A are so grouped that their hooks or bills 10 will be intercurrent with teeth b, radiating from a drum or rollerB, as shown in Figs. 1 and 2. These blades are to be substituted for a plain roller when the har 7o row is to be used in trashy ground, and the action of the blades is such that as the toothed rollers, cylinders, or drums revolve the hook ends of the blades catch the refuse material, and the blades being rigid deliver such material at the rear of the harrow. The said bills or hooks likewise have the effect ot' pulverizing the soil.

In the form of the machine illustrated the frame O is provided with hangers 20, held to 8o slide on the side bars, being secured in adjusted position by set-screws 21, and said hangers journal the trunnions of the cylinders, drums, or rollers B. A sleeve 22 is likewise located near each end of each side bar of the frame, being adjustable thereon and held in position by set-screws or their equivalents, and each sleeve 22 is provided with a lateral extension 23, slotted to receive a pivoted latch 24, the free end of the latch enter- 9o ing the body portion of the sleeve, and the latches are held in locked position by means of pins 25. rlhe standards 19 are provided with notches 2G therein, and these standards are made to enter the rear sleeves 22 from 95 the bottom, and the latches carried by said sleeves are adapted to enter the notches 26 in the standards. Thus the standards may be adjuseed and locked in adjusted position. The forward sleeves 22 receive standards 28, roo in which a plain roller 27 is journaled, and

formed at the upper rear corner of the blade,l 1 these forward standards are likewise provided with notches 29,into which the forward latches 24 enter.

As above stated, theiinproved cleaning device is adapted as a substitute for the rear roller 27, usually employed in machines of the above type, as is shown in Fig. 3, vwhich rear roller is provided with standards 2S, capable of sliding in the rear sleeves 22.

The downward and rearward inclination of the forward edges l2 of the blades serve to direct the trash to the rear, while the upward and rearward inclined edges l1 of the blades serve to cause any trash that might be carried up between adjacent hooks or bills to pass downward or over the hooks or bills.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. In a barrow, a cleaner consisting of a blade provided with a downwardly-curved hook or bill at one end, for the purpose described.

2. A cleaning device for barrow-teeth, consisting of a blade provided with a downwardlycurved bill or hook at its forward end, the top and bottom front portions of the blade being oppositely inclined from said hook or bill, and means for supporting said blade, for the purpose set forth. Y

3. A toothed roller or cylinder, and a series of blades having hooked forward ends arranged intercurrent with the teeth of the said roller or cylinder, for the purpose set forth.

4. The combination, with a frame and a cylinder or roller provided with circularlyarranged rows of teeth, of a series of horizontal blades provided with downwardly-curved hooks o1' bills at their forward ends, arranged intercurrent with the rows of teeth on the drum 0r cylinder, and means for supporting said blades from the said frame, as and for the purpose set forth.
