GEORGE GALHORE, OF SATER, OHIO, ASSIGNOR OF ONE-HALF TO GEORGE VVABNITZ, JR, OF SAME PLACE.

HARROW.

SPECIFICATION forming part of Letters Patent No. 249,830, dated November 22, 1881.

Application filed September 3, 1881. (No model.)

To all whom it may concern Be it known that I, GEORGE GALMORE, of Sater, Hamilton county, Ohio, have invented certain new and useful improvements in Harrows, of which the following is a specification.

My invention consists in arranging two harrow-sections fore and aft, flexibly coupling them together, and providing the rear barrow with a rack, a pair of handles, and connecting- 1o rods, in order that the driver may operate the rock-shafts of one section independently of the rock-shafts of the other section, and thereby adjust the teeth of the implement at any desired angle, as hereinafter more fully explained.

In the annexed drawings, Figure 1 is a plan of my improved harrow, the teeth of the implement being in an erect position. Fig. 2 is a sectionized elevation of the same. Fig. 3 is another sectionized elevation, but showing the teeth of the front harrow inclined rearwardly,

so as to free them from weeds and other trash.

The front section of the harrow consists, essentially, of two stout runners, A A, united by transverse beams B B, the beam B being 2 5 furnished with a suitable coupling, I), to which the team is hitched. J ournaled in the upper part of these runners is a rock-shaft, O, armed with a number of teeth, 0, of any approved construction.

D and E represent two other rock-shafts, disposed parallel with reference to the central one, C, and armed, respectively, with teeth d c.

Projecting rigidly from the main rock-shaft O is a lever, F, having pivoted to it atf a link, G, uniting two levers, H I, secured to the secondary rock-shafts D E.

J is a connecting-rod that unites lever F with its operating-handle X.

b b are couplings uniting the front harrowsection to the beam K, which beam, in connection with another one, K, secures the two rear runners, L L, firmly together, said runners affording bearings for a central rock-shaft, N, and two side shafts, O P, having, respectively, teeth a 0 p. Of these rock-shafts or beams the main one, N, has rigidly secured to it a lever, B, connected by pivot r to a link, S, uniting the levers T U of the auxiliary beams O P.

Secured at one end to the beam K and supported on a standard, k, of the beam K is an so inclined beam, V, carrying at its elevated end a curved bar or plate, W, the edges of which are notched to afford ratchet-teeth w 20, wherewith are engaged handles X X, pivoted, respectively, at w m to standard'lc. 5 5

Y is a connecting-rod that unites lever R with its operating-handle X.

When it is desired to maintain the teeth 0 d e n 0 p in an erect position it is only necessary to engage the handles X X with their appropriate racks w w, as seen in Figs. 1 and 2, and the implement is then employed in the usual manner, the loose couplings b I) causing the rear section to follow, practically, in the path made by the front section. however, as there is a lodgrnent or accumulation of grass, weeds, dirt, and other trash against the teeth 0 d e, the driver has simply to throw the handle X forward, as seen in Fig. 3, which act inclines rearwardly said teeth, and thus frees them from the grass, &c. This handle X, being now restored to its original position, causes the teeth 0 cl 6 to become perpendicular. Evidently the teeth a 0 p of the rear section can be freed from trash in a precisely similar manner by properly operating the other handle, X; but by swinging the handles XX rearwardly the various teeth will be inclined toward the front of the harrow, and thus compel the implement to take more ground. Furthermore, it is evident the rear section, K K L L, can be used alone, in which event the connecting-rod I, handle X, and rack 10 would be dispensed with.

From the above description it is apparent either of the sections can be cleaned without stopping the team or employing any kind of. tool or implement for the purpose, which facility of cleaning preven ts the ground being cut up by deep furrows and ditches caused by 0 grass, weeds, roots, 850., lodging against the teeth. Finally, the teeth, being so readily kept clear of dirt, &c., are not liable to rust and create friction in passing through the ground, and consequently my harrow has a very light 5 draft on the horses.

I am aware it is not new to dispose two or more barrow-sections side by side, as such a As soon, 6

onstruction is seen in several patents, and herefore my improvements are limited to two r more flexibly-coupled sections arranged fore nd aft or in line with each other, and with he teeth-adjusting devices applied to the rear :nplement.

I claim as my invention- 1. The combination of two flexibly-coupled arrow-sections arranged fore and aft, each t said implements being provided with a seies of rock-shafts armed with teeth and deices for operating said'shafts, While the rear ection carries the handles or racks, or their qnivalent devices, for rocking the shafts of ne section independently of the shafts of the ther section, substantially as described.

2. The front barrow-section, A A B B, having the pivoted shafts G c, D d, E e, and devices F f Gr H I J for operating them, and the loosely-coupled rear section, K K L L, 20 having pivoted shafts N n, O 0,1 19, operating devices R 1' S T U Y, double rack w w, and handle X X, whereby the driver is enabled to rock the shafts of one section independently of the shafts of the other section, substantially 25 as herein described.

In testimony whereof I aflix my signature in presence of two witnesses.

GEORGE GALMORE.
