JULIUS HUGO HOOF, OF QUINOY, DAKOTA TERRITORY.
ROTARY HARROW.
SPECIFICATION forming part of Letters Patent No. 291,515, dated January 8, 1884. Application mea August 16,1883. (No model.)
. Be it known that I, J ULIUs H. Hoor, a citizen of the United States, residing at Quincy, in the county of Traill and Territory of Dakota, have invented certain new and useful Improvements in Harrows; and lI Vdo hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and iigures of reference marked thereon.
Figure l of the drawings is a top plan view of a harrow constructed in accordance with my invention; Fig. 2, a rear end view of the same, with the harrow-teeth elevated; Fig. 8, a detail view, showing the manner of connecting the tongue to theframe.
The present invention has relation to certain new and useful improvements in rotary harrows 5 and the object thereof is to improve this class of agriculturalmachines, or what are commonly known as sulky-harrows, 7 7 whereby its effectiveness is materially increased, also its operation simplied, with decreased draft upon the team, as insteadof scattering the dirt it grinds and thoroughly pulverizes it, this being a special advantage when used on lumpy or heavy ground. These several objects I attain by the construction substantially as shown in the drawings and hereinafter described and claimed.
In the accompanying drawings, Arepresents a suitable frame, supporting a horizontal main shaft, B, upon the ends of which areloosely mounted wheels C. These wheels, upon the inner side of their hubs, are provided with clutch-teeth a, with which engage clutches D, adapted to slide on the ends of the main shaft B, and retained in contact with the teeth on the hubs by'a coil-spring, c.` The clutches D are operated by a hand-lever, E, and crankrods b, said rods being pivoted to the frame A, and connected to the clutches at their ends g. This lever E has notches h upon its sides,
in which the bent ends z' of the rods b are located, said lever sliding on a central bar, F,- which has a pin, It, extending up into a slot, l, in the lever, thus forming a guide for, the lever, and also holding it on the bar. Then it is desired to disengage the clutches with the clutch-teeth on the hubs of the wheels, the slotted lever E is moved in the direction of the rear of the harrow, as indicated by the arrow, Fig. l. This willcause the outer. ends, g, of the crank-rods b to be drawn in, and also the clutches D, the springs c automatically keeping the clutch-boxes in contact with the teeth on the wheel-hubs when the slotted lever E is not operated.
Depending from the sides of the frame A are posts G, which form guides for a verticallysliding beam, H, said lbeam forming bearings for vertical shafts I. At the lower end of theV shafts I are rigidly secured harrows K, and to said shafts, above the cross-beam H, are secured vertical pinions L, which mesh with suitable gear-wheels, M, secured to the main shaft B, the shafts I at their upper end having bearings in arms d, projecting horizontally from the inner sides of the frame A.
By the above means the harrows K have imparted to them a continuous horizontal rotary motion, the pinions being vertical and of such length that they will engage at all times with their gear-wheels, no matter how far the cross-beam slides up or down, within prescribed limits, thereby allowing the beam to adjust itself without in the least causing the pinions and gear-wheels to get out of gear with each other.
To raise the harrows K from contact with the surface of the ground, a bent lever, N, is employed, which is secured at one end by suitable means to the front of the central bar, F, and afterward extends downward to connect with the post c. This post projects upwardly from the sliding beam H, and hassecured to it a link, s, through which passes the lever N, said lever extending up within convenient reach of the driver, thereby enabling the horizontal or cross bar H to be raised, and with it the harrows, by means of this lever, as shown in Fig. 2.
The tongue O is connected to a bar, t, as shown in Fig. 3, this bar being pivoted to the sides of the frame A, at the front end thereof, thereby enabling the tongue to be raised or lowered, to accommodate it to different elevations. The tongue O is held at the height to which it is adjusted by a metal strap, m, and pin a, the latter passing through one of a series of holes, p, in the strap, and into a beam, r, arranged directly over the bar t.
It should be noticed that the harrows re- IOO volve horizontally, and in opposite directions va :www
drive-Wheels and suitable gear-Wheels, in coni- I 5 bination with a vertically-sliding cross-beam, vertical shafts carrying horizontally-revolving harrows, and elongated pinions, said beam having connected thereto an elevating-lever, substantially as and for the purpose set forth.
In testimony that I claim the above I have hereunto subscribed my naine in the presence of twowitnesses.
JULIUS HUGO HOOF.
