GRAIN*- DRILL.

SPECIFICATION forming part of Lettersvlatent No. 458,371, dated August 25, 1891.,

Application tiled June 12, 1891. Serial No. 395,999. (No model.)

T0 all whom t may concern:

Be it known that I, DANIEL E. MCSHERRY, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Grain-Drills, of which the following is a specification, reference being had therein to the accompanying drawings, in which- Figure l represents a perspective view of one of myimproved grain shoes or hoes complete; Fig. 2, a vertical sectional view showing the pivotal connection between the wheel or roller and the rear side of the seed boot or spout, and Fig. 3 a detail perspective view of the casting swivelly connecting the wheel to the hoe.

This invention has special relation to graindrills wherein each shoe-runner and hoe carries a spring-depressed pivotally-connected pressure or covering wheel that follows' along in the furrow behind the shoe and serves to yieldingly press the soil down upon and cover the seed dropped in4 the furrow, each wheel operating independently1 of every other and being free to rise and fall and swing laterally as the exigencies of the case may require; and it has for its objects, particularly, the provision of simple and eectual means for making a swiveling connectionof the covering-wheels to the rear sides of the seed spouts or boots of each shoe, so that each wheel will be free to rise and fall independently of the others, and also swing laterally to readily follow the furrow, as will be more fully hereinafter described.

In the drawings annexed, c designates the seed-spout of an ordinary or anyimproved grain hoe or shoe, and as this forms no part of my present invention I do not deem it necessary to further refer to it in this specification.

Riveted or formed integral with the seedspout, on its rear side near its upper end, is a pair of separated rearwardly-proj ectin glu gs or ears b Z), between which is pivoted bya vertical bolt c a laterally-swinging casting d, said vertical pivotalboltpassing downthrough holes in the ears and the intermediate casting and provided with a nut on its lower end. Clamped between the upper end of the casting and the upper ear is the lower horizontal portion of an upwardly extending angular arm e, the upper end or portion e of which is bent horizontally rearwardly. Formed integrally with the swinging casting is a horizontal tube or sleeve d', this sleeve extending across its rear side or edge and having'a passage through it for the horizontal pivotal bolt f. The bolt f pivotally clamps the forward ends of the arms g of the presser-wheel g to the opposite ends of the transverse sleeve d', the presser-wheel being journaled between the rear ends of the arms. At a suitable point between the wheel and the pivotal head is rigidly clamped between the arms, and by means of a horizontal bolt h', a short bar or plate 71., the bolt passing entirely through it and the arms. Pivoted on the bolt h', in an opening in the plate h, is the lower end of a fiat vertical bar 7e, the upper end of which works freely in a slot in the horizontal p01'- tion e of the angular arm. A coiled expansible spring is placed upon the rod It between the arm e and the block h, to keep the wheel yieldingly pressed downwardly.

It will be observed thatV by this construction of the connecting devices the presserwheels will be free to swing both vertically and laterally and at the same time be kept pressed constantly downward, no matter in what position the wheels may be in respect to the hoe. The vertical movement is ativantageous in that it permits the wheels to yield independently of each other in riding over obstructions and undulations in the soil, and the laterally-swinging movement is obviously important in that it permits the wheels to freely follow the furrows whether they be curved or straight. The pivoted arm e is an important feature in that it is free to swing around with the wheel and keep it constantly pressed downwardly. This connection is eX- tremely simple and effectual, and will not be liable to readily get out of order.

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

l. The combination of a grain-drill shoe, a casting or block pivoted on the rear side of the same by a vertical bolt, a transverse sleeve carried by the casting, wheel-carrying arms IOC pivoted to this transverse sleeve, and means for-.depressing the wheel, substantially as described.

2. 'The combination of a grain-drill shoe provlded with ears on its rear side, a casting piyoted between these ears byavertical bolt, this casting having formed integral-with it across its rear side a horizontal tube or sleeve, and arms pivoted to the ends of this sleeve bya horizontal bolt, Said arms carrying a Wheel at then` rear ends, substantially as described.

3. Thev combination of a grain-drill shoe, a laterally-swinging casting pivoted thereto by a Vertical bolt, a horizontal bolt pivoted to the rear side thereof, and vertically-swinging arms pivoted on said bolt, said arms carry- 1ngapresser-wheel,substantiallyasdescribed.

4. The combination of a grain-drill shoe, a
