SECIFIQATION formingpart of Letters Patent No. 685,946, dated November 5, 1901. Original application filed February 28, 1901, Serial No. 49,248. Divided and this application filed July 22, 1901. Serial To otZZ whom it may concern.-
Be it known that I, GEORGE L. ROBY, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new anduseful Improvements in Grain-Drills, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specifica tion.
My invention relates to grain-drills, and more particularly to that class of grain-drills employing spring-pressuredevices for the furrow-openers, whether the same be disks or hoes; and it has for its object the provision of novel means whereby the spring-pressure upon thefurroW-openers may be distributed equally or unequally to enable the drill to do proper work, both on level ground and on hillsides, all as will be hereinafter more fully set forth, and specifically pointed out in the claims. V
In the accompanying drawings, Figure 1 is a sectional side elevation of a grain-drill embodying my invention. Fig. 2 is a rear elevation-of the machine with parts omitted to better illustrate the remaining parts. Fig. 3 is an enlarged detail side elevation, partly in section, of one of the spring-pressure devices and associated parts.
The same letters of reference are used to indicate identical parts in all the figures.
Referring to Figs. 1 and 2, A is the main frame of the drill, of the usual or any suitable construction, supported on an axle B, having on its end the usual carrying-wheels C,which are united to the axle by ratchet-andpawl mechanism in a well-known manner in this class of machines to cause the rotation of the axle forward when the machine is drawn forward or is being turned and to release it from rotation when the machine is being backed.
D is the hopper, carried upon the main frame and provided in its bottom with a series of openings, to which are united in the usual or any suitable manner the feed-cups Ct, containing the usual or any suitably-constructed force-feed wheels fast upon a shaft (No model.)
hopper and extending through openings in all the cups a after a manner well known in grain-drill construction.
The feed-shaft E andthe feed-wheels carried thereby are rotated by driving mechanism from the axle B in a manner described in a prior application of mine to feed the grain in a constant regulated stream from the hopper down through the feed-cups into usual spouts F, suspended therefrom, which convey it to depositing-channels either in the boots of hoes which form the furrow-openers or to sides of disks G near the ground, which disks form the furrow-openers,'the disks and hoes being well known as interchangeable means for forming the furrows in grain-drills and both of which are carried on independent drag-bars H, whose forward ends are pivoted,usually, to the forward cross-bar of the main frame A, as indicated in Fig. l.
The description of the machine sofar is of I a well known type and familiar to those skilled in the art, and I will now proceed to describe the first feature of' my invention for giving an equal or unequal spring-pressure to the furrow-openers.
Heretofore it has been common in graindrills to employa single rock-shaft connected by spring-pressure devices to all of the dragbars or to the hoes or disks for the purpose of forcing the furrow-openers, whether hoes or disks, into the groundto the proper depth and at the same time by reason of the spring connection to permit any hoe or disk to ride independently in passing an obstructiomsuch as a stump or stone, and then immediately resume its proper working position in the ground and by means of the same rock-shaft and connections to raise all of the furrowopeners from the ground in transporting the machine from place to place when not in use. This old method of uniting all of the furrowopeners to a single rock-shaft has been found objectionable in hillside-Work, for the reason that the lower side'of the machine sustain- 5 ing the greater part of the weight would force the furrow-openers from the middle to the lower end ofthe machine into the ground'to a greater depth than the other furrow openers from the middle to the upper end of the machine, which would not be properly forced into the ground, and as a result furrows of unequal depths would be made, the upper f urrows not being sufficiently deep and the lower furrows being deeper than necessary, and to overcome this objection I employ a two-part or divided rock-shaft I, journaled in brackets 11 at each end carried on the main frame A and at their abutting or middle ends in a segment-rack support a, secured to the rear cross-bar of the main frame at its middle. The inner end of the divided shaft 1 has fast to it a hand lock-lever J, engaging the segment-rack C and the inner end of the shaft I has fast upon it a hand-lever K adjacent to the hand-lever J and capable of being locked thereto by means of a segment-arm L, containing a series of perforations with any one of which a pin secured to the lever K in any suitable or convenient manner can be made to engage in order to lock the lever K to the lever J-in any of its adjusted positions, and
thereby lock the shaft 1 to the shaft I when the two have been properly adjust'ed'to each Coiled around the shafts I I are vo-' lute springs A whose rear ends are boltedor made fast to the shaft and whose forwardf ends, straightened out, have secured to them slottedhead-blocks C through which the up-' other.
per ends of the rigid rods N are passed and are engaged by pins e, extending through two i of a series of perforations on the upperandf undersides ofthe head-block, as seenin Fig. 1.
The-lower ends of the rods or bars N are pivoted, asat d,tothe furrow-openersrthe construc tion being such that the forward rotation of *1 the shafts'I I will'put the springs A undertension, therebypressin g down thebars Nto force the furrow-openers into'th'eground to the requireddepth, as will 'be'readily understood.
'lo'l'ift'alll of the bars N and'furrow-openers by the'backward rocking of the shafts II, I provid'ebr'acket-arms B FigsJl and3, which, sey cured to the shafts I I, extend forward and have angular'exten'sions h engaging the under sides'of the springs A near the head-blocks, so
thatin lifting the furrow-openers very little,
if any, strain will be; put upon the sprinfgsAi, and they are not uncoiled bythe lifting of;
the'furrow-openersto any degree whatever,
as will be readily understood. While I'ha've described this particular and novel form of coiled spring-pressure device applied to the rear endsof the furrow-openers, it is to'be understood that my invention in respect to the dividedrock-shaft'andindependent lever mechanismtherefor is not to be limited to thispartkjular form of spring-pressure device as there are a variety of other well--" known forms of" spring-pressure devices c ommon to thegrain-drill artfor applying springmidway, assee'n in Fig. 1, when'thedivided shaft I I is in normal position and all of the springs A are either without tension or are under the same tension, and by operating the lever J under this condition of adjustment all of the furrow-openers are pressed into the ground with equal tension or may be lifted entirely out of the ground, and this is the adjustment used when the machine is working on level ground. Should the machine be worked on a sidehill and assuming that the left-hand end of Fig. 2 was on the upper side of the hill, the lever K would be advanced toward the lever J, thereby imparting a much greater tension to the springs carried by the shaft I than to those carried by the shaft 1, thereby equalizing the depth of penetration of the entire set of furrow openers and insuring the depositing of the seed to the right depth'in the soil. If, on the other hand, the right-hand side of the machine of Fig. 2 was on the elevated sid'e'of the hill, the lever J would be advanced and the lever K drawn backward to give greater pressure to the springs on the right-hand side than to those on the left, as will be readily understood. At the same time it will be observed that both levers are coupled for unitary action through the medium of the hand le'verJ, as will be readily understood.
' This application is a division'of'theapplication filed by me February 28, 1901', Serial ,No. 49,248, and the machine herein illustrated and described is the same as the machine shown in said application, and any sub= ject-matter. claimed by said'application is hereby disclaime'd'in this case.
