` SPECIFIQATION forinng part of Letters Patent No. 477,441, dated J une 21, 1892.

Application filed July 20, 1891.

To lf/ZZ whom t may concern-.-

Be it known that l, WILLIAM H. NAUMAN, a citizen ofthe United States, residing at Dayton, in the county of Montgomery and State 5 of Ohio, have invented certain new and useful Improvements in a Combined Harrow and Seeder, of which the following is a full7 clear, and exact description, reference being had to the accompanying` drawings, forming part of 1o this specification. Y

My invention `relates lto a harrow of the class known as rotary-disk hal-rows, upon which is mounted a seed-box whose feeding mechanism is operated by the disk gangs; and it has for its Object the improvement in construction and mode ot` operation of such machines, the novelty of which will be hercinafter more particularly pointed out and claimed. zo The iirst part of my improvements relates to the construction of the frame-Work which supports the disk gangs and in the method of pivoting the gangs of disks to the frame, whereby the disk gangs, whether set at an angle to each other or in a straight line, will always remain with the butter-heads on theinner end of the gangs in contactwith each other, thus insuring the positive relation of the gangs of disks with each other. In rotarydisk harrows of the ordinary construction, which are provided with butter or anti-friction heads at their inneren'ds,`these anti-tric` tion heads in contactare arranged,ordinarily, to touch when the gangs are set at right angies to the line of draft; but when `the gangs are set at an angle to each otherby operating the shifting-lever, the pivotal connection of the gangs to the supporting-trame being fixed, the anti-friction heads are thrown away from 4a each other as they swing on independent centers, and as a result the strain on the harrow is very largely increased. The object ot my improvement in this respect is to avoid this difficulty and do away with the consequent strain on the machine, and thisl accomplish by providing an oblong slotted hinge connection for the swivels of the gangs, so that the gangs may be allowed to approach each other as they are turned to the angular 5o position. y

The second part of my improvements consean Nn. 400.019. or@ man.)

sists of a novel methodot securing the anti- `friction heads of the gangs, so that they may be easily fastened to the gang-shaft, and yet be free to revolve independently thereof in either direction; and it consists, chiefly, in supplying pins passing through the recessed clamping-heads, which take into an encircling groove or channeled recess in the Vanti-friction head, and thus secure same to the gang- 6o except when actively engaged 4in removing mud or dirt, the contact of the mud with. the scraper automatically throwing it against the disk, while as soon as the mud is removed the scraper drops away from theface of the disk by its own gravity As ordinarily constructed, Scrapers of this description, While they may be independently adjustable, yet when the series of Scrapers are thrown against the disks they rub againstthe same, causing great tric- 8o tion, Whether there is mud to be removed or not, and if theyare angularly adjustable they cannot be in the older constructions at the same time laterally adjusted independent of each other, and it is to overcome these diliculties that this part of my invention is directed.

, The fourth part of my improvements relates to a novelconstruction ot' the force-feed seed-cup for the seeding attachment and to certain novel means for attaching the non-rotating cut-off cylinder to therotatingfeed- Wheel, so that both feed-wheel andcylinder will slide on the feed-shaft and so that each cylinder and feed-Wheel may be independently adj usted with reference to its seed-cup 95 on the reciprocating bar, while the entire seriesof feed-wheels maybe all simultaneously adjusted to sow any quantity of seed by adjusting the reciprocating bar, the novelty of which Will be hereinafter more pointed out and claimed.

Secured to the .gang-frames .iD `D are hangl.g ers vH H, Awithin'which are journaled in the) usual 4manner a gang of-concavo-convex disks K K. These disks are'ixed onsq-uare shafts@ L L, Fig. 7, between spools or sleeves ff in the usual way. rIhe disks and spools being provided with square .openings through 'the center` to fit the shaft are slipped onto the." shaft alternately, each disk being embraced by place. 'The inner disks of each gang are =iit` -ted to clampingheads M M, as'shown rin Fig. 7, which are provided with central cylindrical openings to receive the cylindrical necks Z Z of the independentlyfrevolving` anti-friction heads N N, whose meeting surfaces are convex and are at all times in contact with each other. :ln order to keep these antifriction heads permanently in place, the inner end of the necks-ZZ of the heads are each provided with a circumferential channel or groove m, and a -pin n is inserted through the clamping-head M, so :astto engage withi'nthe p groove m vot 'the anti-triction head, 'and ithus 'thelheadsare y.effectively lheld :fin place.

the bar through which the securing-bolt p passes is slotted, as shown at o, Fig. 10, which enables each scraper to be adj usted within the limits of the slot o along the bar. A slotted cap T, Fig. 11, surrounds the head of the scraper, against which the nut of the bolt p bears in securing the scraper to the bar. This cap is cut away at Y to allow room for the passage of the shank of the scraper, the open` ing Y being slightly wider than the shank, so that in its normal position the shank of the scraper will rest against thev lower edge a' of the opening in the cap. The scrapers are so adjusted on the reciprocating bar that in their normal position their scraping-edges are a shortdistance from the concave surface of their respective disks, so that they will not rub against their disks, but will leave a slight space between the edge of the scraper and the disk, as shown at b', Fig. l0. Should there be any mud or dirt on the face of the disk, however, the edge of the scraper, coming in contact with the mud, will then be thrown up into contact with the disk, so that the shank of the scraper will then bear against and be stopped by the upper edge c' of the capT and the mud will be completely scraped off, when the scraper will at onceV by its own gravity return to its normal position, resting against the face a' of the cap. In this way the scrapers are automatic in their action,

never rubbing against the disks except when engaged in active work, and thus the friction of the machine is very largely decreased. Should the mud be very tenacious, however, the driver by pressing on the foot-leverS can bring the entire series of Scrapers to bear on the disks more strongly than they act under their automatic action. In order that each scraper may likewise be set atany desired angle to the face of the disk, the cap T is slotted at Cl' andthe upper part of the cap is cut away at e', so as to lit up closely against the lower face of the angle-'iron scraper-bar,

as shown in Fig. l0, and it will be manifestl that it' the head of the scraper is iixed in one position on the scraper-bar and the cap T is moved back and forth within the limits of the slot the bearing of the face d' of the cap against the shank of the' scraper" will cause the scraper to swing on the bolt p as a center, and the angle of the' scraper to the bar or to the disk can thus be varied at will.

W XV are a pair of seed boxes or hoppers of the usual construction, rigidly secured to the frames D D by the standards f'f', and braced by straps g' g'. n

Upon one of the spools orsleevesf of each gang of disks is a sprocket-wheel h', from which a sprocket-chain't" extends up to a sprocket-wheel Z', having aclutclrhub m'and loose on the shaft A', journaled in suitable hangers extending down from the seed-box. Keyed to this shaft A', so as to revolve with it,'but adjustable alongthe shaft, is another clutch-hub n', which is thrown intro mesh with the sprocketwheel hubm' by the action f the coiled spring o', surroundingthe shaft A', one end of which bears against the collar B', iixedto the shaft, and the other against the movableclutch-hub n".

C' is a hand-leverconnected with the mov- 4able clutch-huhu' to throw the same out of mesh with the sprocket-wheel hub when the feeding mechanism is not to beoperated.

Upon the end of the shaftV A' is lsecured a pinion D', which meshes with the gear-wheel E' on the feed-shaft F' of the seed-box. This feed-shaft F'is journaled in suitable bearings atthe ends of the seed-box and extends lengthwise across the bottom of the hopper, and is preferably square in cross-section.

At suitable intervals as many seed-cups H, Fig. 8, as may be desirable are arranged along the bottom of the hopper, through the center of each of which thefeed-shaft F' extends.

On this shaft are arranged thelongitudinally uted or ribbed hollow :force-feed wheels G', i

one for each seed-cup.

Alongside ot' each feed-wheel on the feedshat't and preferably of equal diainetertherewith are the smooth cut-off` cylinders L', which are coupled to the feed-Wheels by means ofthe collar or sleeve M', which' at its inner end is provided with a flange s', and is secured to the vfeed-wheel Vso as to revolve with it by the lugp' on the inner face of the feed-wheel taking into a groove or notch in the flange of the collar. At its outer end this collar is provided with a circumferential groove lr', within which a key-plate" N' is inserted, and thus the cut-off cylinder L" is coupled to the feed-wheel.

The collar M' is provided with a square openingt' to fit around the squarefeedshaft and to revolve with it, while its outer cylindrical surface fits loosely in theV cut-off cylinder L', so thatr the collar, and with it the feed-wheel, can revolve Without revolving the cut-offcylinder. Each seed-cup Il is provided with one of these feed-wheels and cutoff cylinders, the farther end of the feed wheel fitting between the flutes of the rim P", which revolves freely in the end of the seed-cup, as usual, to prevent the improper discharge of seed. The other end of the seed-cup has a` cylindrical opening to receive 'the cut-ofi:l

lcylinder L', and is provided with a notch u' to receive the rib o' on the cylinder, which prevents the cylinder L'frozn rotating with the shaft, but allows it to slide horizontally thereon. Through thespace R' in each seedcup the bar S' is passed, and to this bar the feed-wheels and cut-off cylinders are each secured by the bolts w', secured by nuts a", which pass through the bar S' and vthe slots a' y' in the plates T U', one of which plates T' is a part of the key-plate'N' and the other U' is a part of the cut-off cylinder L'.

The sliding bar S', to which the feed-wheels and cut-off cylinders are attached, is provided with an arm or lever A", securely bolted thereto, which arm slide'sover a slotted plate B", securedto the bottom of the hopper, while a thumb-screw b" on the arm A", bearing IIO against this plata-enables the feed-bar S to be secured in any desired position. way the entire series of feed-wheels can simultaneously be adjusted to sow the desired amount of seed. As the bar S is moved it carries with it thevfeed-wheels and cut-ott cylinders and leaves a larger or smaller surface of the feedwheels within the seed-cups to receive the seed and force it from the cup.

Beside this simultaneous adjustment of all each other as the parts wear loose or happen to vary in size in the casting. By moving the key-plate N or its extension T on the plate U it will draw the feed-wheel and cutoff cylinder together. In this way three adj ustments of the parts are possible, and with my improved arrangement all the parts can be cast and readily put together, so that it' any ot the parts become broken they alone need be supplied.

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