IMPROVEMENT IN REIV'OIIIIVING-` SULKY-E'ARROW AND'SEEDER COMBINED.

The Schedule referred to in these Letters Patent and. making rpari: eithe same.

To all whom 'it concord:

Be it known .that I, AUeUsmr L. TAvnAU, of Ohaptico, in the county of St. Marys, in the State 'of' Maryland, have invented a new and useful machine for sowing fertilizers, grain and grass-seed, collectively or separately, and also harrowing in the same, at one operation, under the ttleof The Revolving Snlky- Harrow and Seeder Combined;? and I do hereby de-` clare that the following is a full, clear,'and exact de- Sl'ipin 0f the construction and operation of the same, reference being had to the annexed drawings, making a part of this speciication, in whichf- .Plate No. '1 is a side elevation;

Plate No. 2, a front sectional view;

Plate N o. 3, atop view; and

.Plate N o. 4,12. plan of details.

My invention is intended to perform the general `functions of a' barrow, either separately, or in combination with the seeding-attachment.'

It consists of a spikedcylinder-drum, M, suspended from the axle Lby the arms- D,- which i's held in position by the ystay-chains o, and made to revolve by the gear-wheels B, operating the pinions C on the journals e.

A gear-wheel, No.5, operated also ,by the 'gearing-,v wheel B, engages with No 2, which latter operates the two seeding-pinions, N 0s. -3-a nd 4L A worm onthe inner side of No. 5 operates the grass-seed rod No. 8.

`To enable others 'skilled' in workmanship to make and use my invention, I will proceed to describe its construction and operation.-

Iconstruct rny..revolving sulky-harrow and seeder combined. as follows:

I'take two cast-iron wheels, with cleatson the outer surfaces of' theirrims, and beaxinga flanged gearwheel, fB, on the spokes of the inner side .of each wheel, all'siinilar toreaper-wheels. These are `attachedA to the axle L, supporting the main frame E, and operate the pinions O, which ,are movable, and pass into gear, with the clutches m, at the outer ends of the cyliuderjournals e, by the pressureof thesprings s against the levers H."

' The cylinderM` is of hard wood.

, Thespikes g h are jointed in two parts. The lower joints', h, receive the tenons of the upper joints, g, which are secured below by bolts, and above by the wooden pins o, that breaknpon-encounte'ring any unusual obstruction, and thus save the tooth so striking fromdamage.

Av washer is placed between he'drum and each arm D, to obviate the.grinding of theone against the other.

These arms arefsuspendedfrom the axle L by'iron' straps, bolted throng Y Y' Their lower ends are provided with metal boxes f,

` for supporting the cylinder-Journals e, and a bearingpin, w, to sustain the comb-rod l.

'The braces fr are bolted to the arms D, 'and revolve with them, impinging against the axle, and sustained Y ,The pinions C are movable, and are furnished with spring-pawls, for the purpose of engaging them with'- the clutches m, when pressed into gear by the spring-V levers H.

The, outer ends o f the cylinder-journals e are squared to a shoulder, to receive the clutches m, which are secured by a washer and bolt screwed into the ends of the journals e.

The pinion-levers H iit around the collars 0f the pinions G, and have a mortise through .their centres, to receivel the pivots c.

Their upper ends are furnished with holes, for oscillating on the gearing-rods a, which hook on to the holes in the foot-leverfK.

'This foot-lever K oscillates on a pin-bolt, b, at- .tened-at its end, and secured, by screws,'to the under side of the crosstimber S.

It takes the pinions O ont of gear by engaging with the spring-catch Q.

The main frame E is slightly let in upon aud'bolted to the axle L, and oored over crosswise between the rollers N, and has a spring-seat, G, whose standardv passes down through'the iloorin g, and is bolted against the rear of the axle L in its centre.

main framelil4 by wooden boxes'p, and are conned by iron straps passing over them and keyed to the At eachjend of the. rollers N are iron pin-drums n,

for operating the stay-chains o.

The chains are 'attached to theV lower ends of the arms D, in front, in a ring-bolt, pass around the pindrums n, and are secured by the snap-hooks on the lower ends of the arms D, in the rear. Controlled by the lever P,"ratchets O, and foot-paw] R, they raise the cylinder from the ground, or regulate the depth of its work. v-

This lever Pris secured around the ratchets O by a hinged band, bolted through, and is. provided with two inverse pawls P, for operating theinverse ratch-g ets 0. y

The foot-pawl R is also furnished with two inverse pawls, which reciprocate with the lever-pawls P.

The under side ofthe foot-pawl bar has two slightlyprojecting catches (on its under side) to lift the pawls oli' the ratchets.

This barpivots on the'supportcr t, and is furnished with a sole for the operators foot. y l

The comb l is an iron rod, bent around to such a form as will permit the spikes gto pass within it.,

It is hung on the pin-bolts w, on thelower ends of the arms D, audis supported yby the bracerods w, that arel attached to it by eye-bolts, and hook on to the upper ends of the arms D.

The rear of the comb is furnished with spring-teeth d, secured through holes in the comb-rod l, and then plates.

bent over and around it, and broughtto the front, passing between the spikes 'g, and almost touching the cylinder-drum M.

TheA seed and guano-box No. 1 is formed of two cast-iron head-plates, having grooved flanges on their outer and lower edges, and down their centres, for sustaining the side and bottom planks and division centre-board, and is suspended, at each end, on the main frame E.

A gear-wheel, No.2, is operated by a gear-wheel, No. 5, which latter is double the width of the former in the cogs, for the purpose ot' gearing'intd the main Agear-wheel B and gear-wheel No. 2 simultaneously,

and is' movable on its journal, and is furnished witha lever, U, for taking it in or out of gear with B.

The journal of gear-wheel No. 5 is 'sustained upon the lower edge of the main frame E by a box attached to the same, immediately against .the seed-box No. 1, and its extreme end is supported in a box attached lto that portion ofthe pole E beneath the iiooring.

Upon the inner side of this wheel is a cam-worm, for operating the grass-seed rod No. 8.

-The journal of gear-wheel No. 2 works through a brace, bolted to box N o. 1. Y

This wheel No. 2 is stationary upon its journal, and when in gear with No. 5, operates the two seedingpinions,-Nos. 3 and 4. These two pinions, 3 and4, are' also, like N o. 5, movable on their journals, around-which coil-springs are attached, for pressing their clutches into gear with a permanent pinon the outer ends af their journals.

An extra hole is pierced in each journal, for the purpose of allowing a pin to hold either back, out of gear, when desirable'.

The journals of both these pinions, 3 and 4, passv entirely through N o. 1, and are supported on its head- That of No. 3 is armed with spikes, alter` nating, in its revolutions, between `av stationary row ofA spikes attached to the side of the b'ox No. 1, in front, for pulverizingand passing the guano through the orifices below."

The journal of N o. 4 is mounted with anges, for the purpose of agitating and distributing the vgrain into the orifices beneath.

The box No. 1 is divided, lengthwise, into two equal compartments, for separating the guano' from the grain. Each compartment has a stationary bottom, under which slides, in grooves, a narrow' movable bottom, in a direction opposite to the pinions -3 and 4,-witha hand-strip 'f or operating it.

Both the stationary and sliding bottoms have lengthwise button-hole-shaped orifices, which overlap when theV movable bottoms are closed.

Running the entire length, and attached to the bottom of box No. 1, are two V-shaped tin receivers,l open above and below, against whose sides the grain and guano strike, in their descent, and thus perfect the broad-casting.

No. 6 is the grass-seed box, which is hung from the v rear of the main frame Eby curved, ilat iron braces,

N o. 7, resting in dat hooks onthe frame E.

These hooks are reversed, for the easier removal of rest firmly-in these hooks.

and 'has a wooden notched vibrating traveller, from the top centre of which an eye-bolted rod hooks into connection with rod No. 8, which, in turn, operated o of gear-wheel No. 5, puts the traveller in motion,1ying on the bottom of box No. 6, which thus distributes the seed throughthe holes below.

Both' the boxes No.1 and No.6 have hinged-levers.
