TO ALL WHOM IT MAY CONCERN:

i Be it known that 'MosEs CIIANDLER, of East Corinth, in the county of Penobscot and State of Maine, has inveuted a new and improved Horse-Hec; and we, JOHN C. FLINT, 'of Banger, in the State of Maine, and R. B. DUNN, of Banger, in the same State, ass ignees of said patent bymesne assignments, do' hereby declare that the following is a full, clear, and exact description of the same, reference being hadto the accompanying drawings, making a part of this specification,`in which Figur-e 1 is a plan or top view of the inventon. Figura 2, a side seetional view of the same, taken in the line X X, fig. 1. Similar letters of reference indicate corresponding parts in the two figures. The object of this 'invention is to provide an implement of simple construction,'whic h may be radily' adjusted'so as. to furrow land for planting either in lills or drills, and to form the furrows at a greater orless distance apart, and at a greaterpr less depth, 'as may be desired; the implcment also being so constructed as to be adapted for covering seed in.the drills of a uniform depth, and of any desireddepth; and also to hoe'and hill up growing crops; i I

The nvention consists in the employment of two shares eonverging towards their tear, and made capable of adjustment to or from eachother, either at their front or rear ends, or both.

Also in so attaching or' jointing the forward ends of these shares to their supporting rods as that they may be turned and adjusted tl'ereon, as on c'eztres, u ore or less obliqnely, rolatively to the beam.

'Also in a means for adjusting vertioally the rcar, and also the front ends of these shares, to vary the depth of their pene'tration into the earth. i

Also in appending'to these shares pivoted wings, extending rearwards therefrom. Also in *so connectiig these wings to the shares as that they will partake of their vertical adjustments, and also admit 'oi'being' thrown up out of action when not needed. i i i Also in forming the under side of these wings with a slight eoncave curvature, to round up the dirt as the furrow is covered. i

Also in adjustably securiug and steadying the share-supporting rods to the beam by means of screwthreaded eyes and nuts. v

`Also in the employment of adjustable and yielding eultivator-blades, which are also adapted to be lifted and held out of action when desired.

Also in 'a means for adjusting the cultivator-blades and their'lsupports to or from each other, without unfastening them from the bar to'whichthey are secured. i

Also in a provision'for adjusting the stay-rods which braee the shares, so as to meet the changes of positions of the shares; and in other details hereinafter moutioned.

To enable those skilled in the art fully to understand and construct a. horse-hee and cultivator made in accordance with the invention, 'I will p'occed to describe it.

A represents the beam of the implement, the back part of which has two handles, B B, attached tojt of the usuol form. C"s a cross-bar, which is attached to thebeamA at a point a short distance in front of the lower ends of the handles B B. Thiscross-barprojects a't equal distances from the'beau A at each side, and on said bar C, at each side of the beam, there is itted a spiral or coil, a, of a stout metal bar or rod, D, the inner ends of the spirals or coils-being attached to the bean A, as shown at b. The spi'als or coils a form springs for the rods D, and each rod, at about midway between its free end and bar C, is wound into a single coil or loop to receive the ends of bar E, the rods being retained in p'roper place on bar E by pins e( To the lower end of v each rod D there is attached a cultivator-blade, F. The' force exerted by the coila tends always to bear the blade forward against the pull of the chain. Each rod, D, has a chain, G, attached to it, said chains being connected to the beam A. By taking u'p or lengthening these ch'ains on the beam ^A, in any well-known manner, the -ods D may be more or less nclined, and the depth of the penetration ofthe blades F in the earth regu I lated as desired. Whiflle-trees are attached to the ends of the cross-bar C. H H represent two shares, and

their pivoted wings or blades, d designating the share, and e the wing or blade, slightly orvedon its under side, the two being connected together by'a pivot or`bolt, The shares ci are attached to curved or bent rods I J, which are secured to the under side of the bea'mA by eyes or loops g at the lower ends of thescrew-bolt K, which pass through the heam, -as shown clearly in fig. 2. The front ends of the parts d of the wings H are attached by joints h to the rods I, so that said parts d may be turned thereon, and adjusted, more or less obliquely, relatively to the heam A, and also raised or lowered by means of the screw-thread and nut on the rods, and the back eds of the parte d are attacled to the rods J, by the pivots or bolts f, which pass. through oblong vertical slots i in the lower parts of the rods J', and are adjustable thei-ein. By means of these pr6- Visions for djustment, the shares may be lowered or raised at will and held in the desired position, either at V their front or reat ends, or both. To. the front endof each part, d ,of the wings, there is attached a stay-red,

dina1s1ot,j,in thebeam 'A i T The implement is used as follows: When drills are to be made, the shares are adjusted so as to be nearly L., The front ends of'the rods L are attached-to the lower end of a bolt, M, which is fitted in a loig'itu- -paral-lel with each other, and-at a distance apart corresponding with the required distance between the drills.

This may be-effected by adjusting the rods I J' longitudinally to the proper positions in the eyes qof `the bolts K, and securing them firmly in such positions;

In forming or making furrows,the cultivator-blades -F may be drawu up free from the ground, and retained in such position b the chains G. The greater the angle to which the shares are adjusted relatively to each other, the deeper will be thefurrows. i

In covering seed in drills, the shares d are placed in a more or less oblique position relatively to the beam, and the wings e are more or less elevated, 'according to the height of the ridge of earth required over the seed.

'The higher the wings eare raised, the higher the ridge of earth will be, and 'vice vai-sa, and the greater their curvature on the under side, the more will the top of the ridge be rounded oh'. The depth of the penetration of the shares d in the earth may be graduated by raising their rea'r ends', the slots 'z' in the lower parts of the rods J admitting of sch adjustment. It will bc seen that the shares and their blades or wings will throw earth upon both sides of the growing plants, and as near torthe same as -may'bedesirable, and when used for such purpose the cultivato r-blades F F are lowered by lengthening the chains G, so that they may act upon'the earth and serve to loosen or lighten up'the same, and deprive it of weeds. The springs of the rods Dare snfliciently strong to allow the bladesF to pass throughthe earth and perform their proper functions, but theywillyield' or givein case the blades meet with any obstruction in the earth, and will therefore prevent the rods being broken orinjured orany parte connected therewith being strained. -They also allow the lateral adjustment of the blades F. The blades F F may be adjusted at a greater or less distance apartby slidingthe rods DDon the bar E, and securing them nearer` together or further apart by means of the pin a. The stay-rods L are adjusted to suit the difi'ei'ent .adjustments of the shares d by means of the adjustable bolt M in the'slot j of the beam,'a nut thereon serving to'secure the bolt firmly in thedesired position;

It is evident'that-my improved implement isadapted for great Varieties of crops, not being confined in its uses to any particular Vegetable production. It will be perc'eived from the above description that ;this single machine, both simple and.. cheap, has a very 'wide'range of usefulness, comprising literallywithin itself the,

fupctions of a drill, a drill-coverer, (hillinf'g up from both sides of the dri1l, a cultivator, and a weeder, the parts being easily adjusted, or thrown out ofaction, for the performance of these different dutics, and also for performing them in diiferent ways, and under di'erent conditions;

furrow is covered.
