SPECIFICATION forming part of LettersfPatent No. 756,095, dated March 29, 1904.

Applicationiled May v28, 1903.

T0 all whom, it may concern:

Beit known that I, ROBERT D. BRowNING, a citizen of the United States, and a resident ofy Orange, in the county of Orange' and State of Virginia, have made certain new and useful Improvements in Grain-Drills, of which the following is a specification.

The object of my invention is to provide' simple and effective means for regulatingthe depth that the disks of disk-drills shall run iny the ground, and is specially adapted to hilly or rolling land, the disks being divided into sets, preferably a set on each side of the center of the drill and having means for regulating each set independently of the other and for locking the sets in anyl desired adjustment with reference to each other.

The special construction and operation of my improvement will now be set forth in detail in the appendedspecication*and its novel features pointed out and claimed, reference being had to the accompanying drawings, in whichv y Figure l is a rear elevation ofthe skeleton of adisk-drill provided with my improvement, parts` of the same being shown in section. Fig. 2 is a central vertical section through Fig.` k1 on about line-.2 2, looking to the left and yshowing the left portion of my regulating device. Fig. 3 is a perspective view of one of the shaft-heads and its bearings. Fig. 4L is a rear elevation of the inner ends of thev shaftsections and theirheads and supporting-stands.

Referring to the drawings, A is a disk-drill having the two sets of disks B and B. In the construction shown the grain-drill, which may arms D3 and D, carried by the twosections ofthe divided bar D at the rear of the drill. This barDhas its outer ends journaled in suitable bearings A4 on the frame of the drill and corresponds to the bar usually employed in drills for raising and lowering the plows. It is preferably made square to permit the crankarms D3 and D4 and the heads at the inner `heads form rotatable supports for the inner Serial (No. 159,097. (No model.)

Y ends of the two sections of the bar to be more easily secured thereto against rotation.

Special attention is now called tothe parts at the 4inner` ends of the sections D 4and D2 of the bar D. Two similarheads E andF are provided with central apertures or bores E and F', respectively, into which are received andrigidlysecured bybolts or otherwise the inner ends of the' sections D and D2 of the divided bar. At their innerends these heads are in abutting engagement with each other, x and the central aperture E of the head E has a reduced portion E2 at its inner `end, which extends outwardlyfrom the inner end of the bar D', while the bar D2' extends inwardly from the head F and has its inner end projecting beyondv the face of said head and formed into a journal adapted to be received into said reduced bore E2 of the head E. These ends of the sections D and of the divided bar, said heads' being mounted to turn -in vthe* angular supporting-stands E3 and F3, respectively. These stands have angular flanges or f feet at their lower ends by which they are'secured to the rear transverse ,bar A5 of the drill-frame. The heads and Fare each provided near their inner ends With similarupwardly -extending lever-y arms E4 and Fi,

having at their upper ends outwardly-turned handles` The inner faces of 'said'supportingstandards are preferably brought into engage# y y ment with the outer faces ofsaid arms, which arrangement prevents the heads E and Fl from pulling apart from each other. i y

The standard E3 is'provided with a rackl segmentfEr. The lever-arm E? carries on its outer face a pawl E6, adapted to engage the rack E5 and connected. with a handle-lever E7, D by which it may be released at will. The lever-arm'Ei also carries on its inner side the rack E8, rigidly secured vthereto by bolts or otherwise. The` lever-arm F* carries on its inner side a pawl F5, similar to the pawl EG carried on the armA E'and the vpawl F5 is 95 adapted to engage the rack E8. This pawl F 5 has a releasing handle-lever F6. The head handle-levers on the two operating-arms E4 g and F4 are connected with their respective pawls Aby suitable. connecting-rods.

IOO

It will be seen that the pawl F5 when in engagement with the rack Es locks the two heads E and F together. In this condition the two heads and the two sections of the divided bar controlling the whole series of plows or disks may be rotated in unison by the lever E4 and may be held in any desired position by engaging the pawl E with the rack E5. If, however, it is desired to raise or lower the group of disks controlled by the section D2 of the divided bar with reference to the other group, this may be readily effected by the lever I"4 when its pawl has been disengaged from the rack E8. When the two sets of disks are brought into the desired relative elevation to each other, they are locked in this position by the pawl F5 and the rack E8. Hence I have a divided bar or shaft with its shaft-sections having supporting-heads in pivotal engagement at their meeting ends, and an operating-lever for each section by which each may be rotated independently of the other, combined with mechanism for locking the two bars in any desired position relative to each other, and, further, means for then rotating the bars in unison with each other as if they constituted but a single bar, the mechanism employed to control the two sections of the bar independently of each other being utilized to perform all the operations mentioned.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination with separate shaft-sections, of heads secu red on the adjacent ends of said sections, stands having bearings for said heads, a rack-segment on one of said stands, a handle-lever on the head journaled in the stand provided with the rack-segment, a pawl on said lever for engaging such rack-segment, a

rack-segment in connection with said handlelever, and a handle-lever on the otherhead and provided with a pawl for engagement with the said latter rack-segment.

2. The combination of two shaft-sections in alinement, an independent support for the inner end of each shaft-section, ind ependent rocking means at the adjacent ends of said shaftsections., devices for locking the rocking means of the first section in any desired position, devices for locking the rocking means of the second shaft-section to those for rocking the first shaft-section, and means at the adjacent ends of the shaft-sections to prevent said sections from pulling in a direction from each other.

3. The combination of the shaft-sections means for rocking one of said sections, devices for locking said means in any desired adjustment, means for rocking the other shaft-section, devices for locking said rocking means to the rocking means of the lirst shaft-section, and means at the adjacent ends of the shaftsections to hold said sections against movement in a direction from each other.
