Specification of Letters Patent. Paeeneeqi lnn" its Application filed January 6, 191%). .fierisffio. 5.3385 5%a of which thofollowing is specification.

This invention relates to improvements in jointers for plows, nntl has for its objectto provide :1 simple, strong, effective and inexpensive device, which capable of? being readily and quickly attached to the beam of a plow ztlltl is also adjustable to tliiltlOliil service positions.

A particular object oi the invention is to provide a jointer for splitting, skimming and turning over the top of the lt'nrrmvslice in advance 'ol the turning operation by the main plow; the jointer being positioned intermediate the point of the share and the mold-board of the. plat, one point of the jointer overlapping illltlyieldingly held against one side of the colt-er.

It further object to provide a jointer which is reversible, and which. may he i1(.l jnstecl so as to throw the surface soil or sod in different directions as compared with the throw oi. the reniaiiuler of tl i'urrowslice. And 2L fuitlieii is provide device of the class which will increase the elieetiveness of the work of a coinnmn plow without incrensing the draft.

The dispos lg .e jointer an inch or two -eerwi cutting E) of the when, latter to do its work few and owing to the feet th bears against the Coll er at 7' there is verylittle, if- 7 draft. From the point of cont-not lo the cotter and jointer, the latter then curves upwardly and outwardly away from the colter, thus providing a large clear gap between these two parts, through which weeds, grass, and clods may pass freely withoutany tendency to clog the plow.

As may be seen by reference to Figs. 2 and 3, the gap between thejointer and colter increases from'the point of contact upwardly by the outward curving, of the jointer. .The form and arrangementof these auxiliary parts are such that there are no points, corners or angles to gather, or to obstruct the free passage of, the earth and refuse, during the operation of the plow. In the preferred arrangement and disposition of the jointer and colter, the lower extremities of both of these parts are preferably spaced and held a few inches above and clear of the share of the plow, and they should also be disposed several niches rearwardly of the point of the share. By arranging the colter and jointer in the manner herein shown and described, these parts have a tendency to steady or balance the plow, and by the peculiar arrangement and relation of the jointer and colter toeach other, as well as to the plow, I am able to skim off the top of the soil and turn it over,

' in advance of the large mold-board, which 30 immediately follows, picks up and turns over the substrata of the furrow-slice, thereby com- ,pletely covering up the entire top surface.

Under this construction, arran ement and operation of a plow, equippe with my jointer, every particle of the top orv surface-soil, including grass, stubble, &c., is completely turned over and buried. By changing the shape or angle of the shank 13, the jointer may be set at a greater or less angle as compared with the mold-board 5, for the purpose of varying the work of the jointer. The same result may also be attained, though in a limited degree, by adjusting the jointer to differentpositions on the shank 13, by means of the bolt 14h It is obvious that some changes and modifications may be made in the device, and in v the application of the same, wit-hout'departing from. the spirit of my invention, and I therefore do not restrict myself to precise construction, arrangement and application of the same as herein shown and described.

Having thus described my invention what I claim as new and desire to secure by Letters Patent, 'is I 1. In a plow-jointer, the combination with the colter .of a plow, of an adjustable plate pointed at its opposite ends, its body curved to form a reversible mold-board adapted for cutting and turning over the surface soil, a

spring shank for supporting the said plate,

arranged to hold the forward point of the plate against one side of the colter, means for adjustably securing the plate to the shank, and means for clamping the plate and colter to the beam and holding the plate against the colter under a constant spring tenslon.

2. In a Pl0W-]O1I1t1, the combinatlon with a colter carried by the beam of a plow, of

' a constant spring tension, said shank having its lower end formed to hold the opposite or rearward point of the j-pinter away from the colter to provide a gap increasing in width from the forward point of the jointer to the opposite end thereof, the said forward point of the jointer being positioned rearwardly of the cutting edge ofthe colter, means for clamping the shank of the jointer to the beam and drawing the jointcr against the colter and means for adjustably' securing the jointer at ditt'erent angles to the springshank.

The combination with a plow. and a colter supported by the beam of the plow, of a spring-shank mounted on the opposite side of the beam to the colter and depending coincidingly with the colter, a jointer comprising a curved-plate having like entering points formed at its opposite ends, the said plate attached to the lower end of the spring-shank andadapted to be held by the tension of said shank so that its forwardpoint bears against the furrow-side under a constant spring tension, and rearwardly of the cutting edge, of the colter, a bolt piercing thesaid plate and also said shankfor rigidly holding the jointer in place, and means for clamping the jointer under'a constant spring tension against the colter.

In testimony whereof I affix my signature in presence of two witnesses.
