`Specitlcation forming part of `Letters PatentNo. 53,459, dated March Q7, 1866; reissneNo. 6,078, dated October 6, 1874;' application filed August 31,1874.

To all `whom it may concern: f Be it known thatr we, DANIEL. LUsE and DANIEL F. LUSE, of Centre Hall, formerly. of Spring Mills, in the county of lCentre and State of Pennsylvania, have invented certain new and useful Improvements in .Corn-Planters'. of which the following is a specification: Thisinvention relates to that class of cornplanters in which the seed is dropped by a 4disk revolving within the hopper; and conages, and Fig. 5 a central vertical section of the seed-brush and its fastenings.

We ordinarilyemploy a common triangular frame, A, supported'by two wheels, B, near the rear end, and gaged in height by a casterwheel, a, in front. 'The seed-box() is situated as usual, and is provided'with an ordinaryv dropping-disk, l), which `may `be revolved in any appropriate manner by connecting mechanism underneath. Gr is a brush., located within the seed-box on the circle of the seedholes p, and preferably in acovc, as shown in Fig. 3, so that seed cannotl enter these holes between the brush and the delivery-hole. This l brush is adjustable, so that it may be raised or lowered as may be necessary, dependingL on the size of the grain to be dropped. ,orthe quantity desired to be dropped, and `when so adjusted prevents more than the desired `quantity of grain being carried under it by the relvolving disk to the ,delivery-opening. It is made round, sov that when one side becomes worn by the action of the-jseed'it maybe turned to present a new front..\' We prefer lto confine the bristles forming the brush in a' tube, open or lclosed at they top,` which serves as a. handle;-bnt theymay beconned by wrapping, or in any well-know'n'. and .approq priate manner;v on' isa curved hook,-embrac J ingthebrush, as shown, andhaving a screwshank reaching back through the-side of the seed-box,- and securedby a'.V lint, fn, which tightens the brush, as desired, 'and allows it to be'adjusted atpleasure. Then ythe brush reaches up to the cover of theA seed-box, or is i prevented from rising .by any appropriate means, thecurved hook m need not be screwed up vso as to tightly engage the brush, but vmay loosely'engage it,- so as to allow it to revolve and adjust itself as to wea-r, though we prefer to have the hook tightly hold the brush. The drill-tooth Iy is fastened to a swinging bail, L, of crankform, whose bearingsll are above the under-'side of the frame. A flange, t, Fig. 4, projecting upward from the ybail at the center, and provided' with a bolt hole or i holes, serves to attach'the drillftooth tothe bail; There is a set 'of bolt-holes, o o, inthe upperf part", of ythe drill-tooth, '-by which v t-he depth of the drill-tooths running maybeadjusted to any desired extent, whiletheswinging ofthe bail enables the drill-tooth to bead! justed also to anyangledesired. In order to adjust this angle a rod, m, is `hingedlto the. drill-tooth at s, and extends thence ,forwardl and lupward through theframe of the Inachine, and terminates .in "a screw-thread, sov

-that anut, r, thereon adjusts the length of the rod, as desired. a .wooden pin, which will break when any'oblstruction strikes the drill-tooth,thereby cans ing the same to give way without injury to the machine. The plow or furrow-clearer N in front ofthe drill-tooth has a regular double share, w, and two regular or complete,y

mold-boards or wings, e r1w'l1ereby not only turfs and other `undesirable obstructions are pushedaside from the furrow, but are turned'- away like a furrow-slice,k thus invariablyinsuring the completeremoval of: the obstrucl tions from thevrows, and: leaving the ground f fine and clear at and near the furrow. l `f We are aware that furrow openers and clearersofvarious forms have been" used before,

but so `rfar aswe are advised.A no` previous arrangement `of'a \doubl'e lshare and a double rlhe joint at s may have mold-board plow or furrow-c1earer, completely turning furrows both ways, have been used in this connection;

XVe have shown suitable mechanism connecting the gear 011 the driving-shaft and the revolving disk for operating the machine, but any other known appropriate mechanism may. be used.

Having thus described our invention, what we claim as new, and desire to secure by Lettersr Patent, is-

1. The bail L, provided with the attaching and adjusting ange t, and angle-adjusting rod m., for mounting the drill-tooth upon, substantially as and for the purpose herein specied.

2. The double share and full double mold.-- board furrow-clearing plow fw, in combination with the drill-tooth I, substantially as and for 1 the purpose herein set forth.

3. A vertically and circularly adjustable n brush, arranged in front of the seed-delivery opening, for the purpose ofregulating the quantity of seed dropped, and freeing it, before being dropped, from the lmass of seed in the hopper, substantially as specified.

4. In the seed-box, the cove, as shown,l for A
