SPECIFICATION forming part of Letters Patent. No. 343,168, dated June 8, 1886.

Application filed October 531, 1885. Serial No. 180,538. (No model.)

To aZZ whom it may concern:

Be it known that I, PATRICK P. GARDNER, a citizen of the United States, residing at Bradford, in the county of McKean and State of Pennsylvania, have invented a new and useful Improvement in a Combined Cultivator, Corn-Planter, Rake, and Roller, of which the following is a specification,reference being had to the accompanying drawings.

My inventiourelates to improvements in a combined seeding and cultivating machine; and it consists in the novel construction and combination of thevarious parts, substantially as hereinafter fully set forth, and specifically pointed out in the claims.

6 is a view in detail of one end of the axle or driving-shaft. Fig. 7 is a View of the contin uously-reciproeating rake and the pressureroller. Fig. Sis a top plan view of the hop; per with the slide therein.

Referring by letter to the annexed drawings, in which similar letters of referencede; note corresponding parts in all the figures, A designates the frame of'my improved cultivator and seeder, which consists of a middle 3 5 longitudinal beam, a, and two side beams,'c,

arranged in an inclined position or at an angle thereto, and in the same horizontal plane, the forward ends of said inclined beams a being secured or connected to the'middle beam, a, At or near, the middle the inclined side beams are connected and braced by a curved bar, a, andthe middle beam, to, is provided with bearing; blocks or shoulders a to which the forward lower ends of the handles B are pivotally com nected. The forward end of the middle beam, a, is bent upwardly or provided with an in clined neck, 0. The'verticalside faces of the bent end of the middle beam are" recessed as at c and have transverse apertures c c 0 D is abearingroller ournaled'in abracket,

. Fig. 1. planter, only the first three cultivator-blades are employed; but when the seed and fertilizer Z, pivoted or swiveledat its upper end in a supporting-band, D, having apertures 11 (1 through the upper end of which a pin, (2 passes topivotally connect said band D to the inclined neck or end of the middle beam. The roller is held in a vertical position when the device is used as a seeder by means of a pin, D", that passes through the lower aperture, (1, of the band D and the'aperture c" of the beam; and when the machine is used as a cultivator the band is adjusted so as to bring its lower. aperture, (1 to register with the aperture 0 and thus bring the roller out of contact with the ground.

Edesign'ates a draft-link pivotally connect ed at its rear end to a bracket or loop, 0, and having a' longitudinal slot, ,cf, near its front end, through which slot a curved arm, E, passes. A wiftletreeis connected to an eye at thefront' end of the link E, to draw the machine forward, and the curved arm Ehas two or'more apertures, 6', through one of which a stop pin-or bolt-,6, passes to limit theplay of the said draftliukl l. The upperends of the handles B are braced and connected by crossbars I), and the side bars of said handles are provided with twov or more apertures, b, through which the upper ends of the bracerods 1) are passed to secure the handles firmly and securely in position, while at the same time permitting them to be adjusted nearer to or farther from the frame of the planter, the lower ends 'of said brace-rods I) being pivotally connectedto eyes b, secured to the rear ends of the side beams of theframeA... 3 F designates shovels or cultivator-blades se-I cured to the under surface of themiddle and side beams, a a, and arranged as shown in When the machine is to be used as a drOppingdeVicesare to bethrown outof use and the machine used as a cultivator all of the cultivator-blades, fivein number, are used-to throw the earth upon the corn or hills."

G designates a tahle' orj platform secured upon the main frame and'sup porting the hop per, its seed-slide actuating devices, the ma'rk{ er, and the continuously-moving rak'er framej as will be presently described. The table is preferably made in two longitudinal sections,

LII

g g, which are detachably fitted and bolted together and to the main frame A, to permit ready access to the various parts for the purpose of repairs, &c.

H designates the driving and supporting wheels to the rear end of the main frame, said wheels being loosely mounted on a shaft, H. The driving-wheels are provided with pawls ii, that are normally kept in engagement with ratchels h on the shaft H, to rotate the same; and the ends of this shaft are supported in the lower ends of supportingbrackets I. These brackets comprise two arms, '5 i, arranged at an angle to each other, the, arm 1' of each brack et being pivoted at its front end to a recessed portion of the side beams of the main frame and the arm i thereof having two or more apertures, 77', through one of which a lockinglatch, 1, is adapted to pass to hold the axle securely in place while permitting of its vertical adjustment, said latch I being pivoted to the upper face of the rear ends of the side beams of the frame. The arms 1" are arranged between the inner faces of the side beams. and gnide'plates 1, and when the latch 1 is out of engagement therewith the shaft or axle and d rivi fig-wheels are free to move or reciprocate up and down on the pivot of the arms z, and thus accommodate the main frame for use as a cultivator, to permit the blades to enter the ground to any desired depth; but when the machine is to be used as a seed-planter the latches l are thrown into engagement with one of the apertures of each of the arms f, a pawl, I, limiting the upward adjustment of the brackets I, by fitting in the angle formed by the arms '5 i thereof and pivoted to the in ner faces of the side beams, a. The driving shaft oraxle carries at or near its middle a beveled gear wheel or pinion,j, that meshes with a similar pinion, j, on a: shaft, J, jour naled in boxes j. These boxes j" are mounted or secured so as to slide laterally in ways or blocks k, secured to the under surface of the table section and to the rear one of these boxes 9" is connected a pin of a lever, K, pivoted at k" to the table-section g, and extending rearwardly beyond the same within convenient reach of the operator, who grasps the handles B to guide the machine, whereby, when the lever K is adjusted, or its front end th rown, inwardly toward, the middle of the tablesec tion 9, the journal-box j" of the rear end of 1 the shaft J will also be thrown or moved toward the middle of the table and out of its normal position, and will carry with it the with the wheel j of the driving-shaft, this mechanism being provided for throwing the drivingshaft out of engagement with the seed-slide-actuating devices.

L designates the hopper, secured upon the front end of the table G, and divided into two compartments, l Z,'by a vertical partition, I, one of said compartments being adapted to and, equal distribution of fertilizer. ciproeating slide M is provided at one edge ceive a fertilizing substance. Each of the compartments of the hopper has a dischargeopening, Z, in its bottom, and each opening is covered or protected by an independent slide, 1, which slides work in grooves provided therefor in its bottom. Each slide 1 can be adjusted to any desired distance, by hand, to

Q regulatethe amount of corn or fertilizer to be distributed, and they can be used to shut off the discharge of seed or fertilizer, or they may i be adjusted to permit only seed or fertilizer to be sown independently of each other.

M designates the reciprocating seed-slide,

, arranged to slide in ways or guides beneath the hopper, to permit the discharge at predetermined and at regular intervals, and to secure an even and regular planting of the corn The rewith a single aperture or discharge-opening,

, m, which lies beneath-the discharge-opening in the compartment for the corn; and at its Y opposite edge said reciprocating slide is provided with a series of smaller openings, m.

' which are arranged to register with and cut off the material from the dischargeexit from the fertilizer-compartment of said hopper.

M designates a'bell-crank lever pivoted to the table-section g at, the junction of its two arms, one arm of said lever being pivotally connected to the reciprocating seed-slide M, to actuate the same, and the other arm thereof is slottedat its other end, as at n, and fitted over a headed stud, n, to pivotally connect the said arm to a reciprocating bar or link, N. This reciprocating bar or link N is fitted to slide longitudinall y of the table within a groove formed in the lower section, g, thereof, and at its rear end it has, lip or tongue, a that projects through a slot or cut-away portion, a of the lower table-section, g, at or near the middle thereof.

O designates a shaft arranged transversely across the lower surface of the table G and the slot at in the lower section thereof, and said shaft journaled in bearings 0 at the sides of the table, This shaft is provided with a bevel gear-wheel, 0 that meshes with a similar gear-wheel, O", on the rear end of the shaft J, and said shaft 0 is revolved through motion, from the driving-shaft H, transmitted by the shaft J and the bevel gear-wheels j jOO", as clearly shown in Fig. 2. The shaft 0 projects at one end beyond the maehineframe and table, and is provided with a marker-arm, O, that is rotated and strikes the ground at regular predetermined intervals as the shaft 0 is revolved, and said shaft is further provided with bent crank-arms 1), that are connected near their lower ends by a crossbar, 1), said crank-arms revolving with, the shaft and working in the slot or cut-away portion n of the table.

I designates a shaft journaled in bearings p on the lower face of the platform, and having a crank-arm, g, at its middle that pro receive corn or other seed and the other torejects through a slot in the table-section g, and

said arm is pivotally connected to a link, Q, that works or reciprocates in a groove or guide in the upper surface of the table-section, and at its front end said link Qis provided with a tongue, q, that projects through the opening or slot a and is normally kept in the path of rotation of the crank-arm of the shaft 0, and serves to cause the shaft 1? to oscillate in its bearings for a purpose presently described. The link N has its lip also normally held in the path of rotation of the crank of the shaft 0 by means of a spring, 1-, rigidly secured at one end to the table-section gand bearing at its opposite free end on a shoulder or lug, r, of the bell-crank M, this spring serving to hold the reciprocating seed-slidethrough the medium of one arm of the bell-crank lever, so that its discharge-openings m m do not register with the openings in the bottom of the hopper to cut off the flow of seed and fertilizer, and in addition to holding the tongue of the link in the plane of rotation of the crank of the shaft 0, so that when the tongue of the link is struck by the crank in its rotation the link-N will be drawn rearwardly, turn or oscillate the bell-crank lever M on its pivot, and reciprocate the seed -'slide so that its discharge-apertures m at will register with the apertures in the bottom of the hopper and with the opening 8, formed or cut in the tablesection g, to permit the passage of the corn and fertilizer from the platform or table and hopper to the ground, and after the crank has ceased to act upon the tongue of the link to draw it rearwardly the spring 1' serves to force said link forwardly again to its normal position, and to draw the seed-slide apertures from coincidence with hopper and platform apertures, to cut off the discharge of seed and fertilizer.

S designates a rakebar having a series of teeth, 8 s", arranged to actupon the ground, to clear the furrow of leaves, stones, &c., said rake-bar being arranged in rear of the machine and supported in curved side bars, S, which extend upwardly and forwardly of the machine-platform. The side bars, S, are connected together at their front ends by a crossbar, S which fits between the table-sections g g and in a groove in the lower surface of the upper section, 9. The side bars lie alongside of the side edges of the table or platform, and are provided with loops or eyes t at or near the point where the ends of the shaft P project from the side edges of the platform or table, the ends of said shaft being bent to form crank-arms t, which engage or fit in the loops t of the raker-frame S S", and serve to reciprocate said frame to give the rake-bar S a continuous vertical movement when the shaft 1? is oscillated through motion from the crankshaft 0, transmitted by the link Q. The weight 0, except when its said link is forced rearthus oscillate the shaft P and reciprocate the raker-frame. The front cross-bar, S lies over the rear end of the link N, and is normally kept depressed upon said link, to keep the latter in place by means of a spring, 8 secured at one end within a recess in the upper table-section, and free at its other end to bear on said link N and cross-bar S", which serves as a pivot for the raker-frame in its reciproeating movements. The seed-slide and rakerframe reciprocating devices are all hid from View and protected by the upper table-section,

g, which is recessed or cut away on its under surface at proper points, to permit of the proper movement of the various devices, said section 9 being detachably secured or bolted to the table-section g, to permit its ready removal for the purpose of repairs, &c.

T designates a rollerjournaled in the side bars of the roller-frame T, the front ends of which are pivoted to arms U in rear of the raker-bar S, and said frame and roller are free to work or move independent ofthe rakerbar and frame, beingloosely connected to said frame and of such a weight as to keep the roller in contact with the ground at all times. The gear-wheels jj are keyed on their shafts H J, so as to permit of their removal and exchange for similar wheels having a different number of teeth, so that the seed'slide can be operated more rapidly or at a slower rate, to vary the distance apart at which the seed and fertilizer are distributed, as will be very readily understood.

The machine may be converted into a drill by attaching a conducting tube or spout or boot to the under surface of themiddle beam,

(1, so that it will register with the dischargeopening 3 therein, and guide the seed and fertilizer to the hill. The teeth 8 of the rakebar S are arranged at each end of the said bar, and are longer than the teeth 8 thereof, which are arranged between the outer teeth, 8. The shorter teeth, 8", serve to gather-up the stones and leaves, 810., and deposit them at regular intervals by the reciprocation of the rakerframe, and when the machine is used as a cultivator the raker-frame ceases its reciprocatory movements, and the raker-teeth s carry-the stones and leaves, 850., with it, until, when crossing a hill, the longer teeth, 8", elevate the frame and bar a sufficient distance'to permit the stones, &c., to escape from the teeth 3", and are deposited in the furrow between the hills.

- The operation of my invention is obvious. \Vhen the machine is to be used as a cornplanter and fertilizerdistributer, the seedslides Z are properly adjusted to regulate the quantity of seed and fertilizer to be distributed, and the bevel-wheel j of the shaft J thrown into engagement with the bevel-wheel of the shaft H. \Vhen the machine is drawn across the field (the horse being attached to the draft linkE and the caster-wheel D, and bearing- IIO cillates the bell-crank lever M, which reciprocates the seed-slide, and the slide, link, and

bell-crank are forced back to their normal positions by the spring 1', to bring the tongue of the link in the path of the crank to be acted upon again, to repeat the above movements. The tongue of the link Q, when struck by the crank of the shaft 0, forces said link rearwardly and oscillates the shaft 1?, which in turn reciprocates the raker-frame, giving a continuous vertical movement thereto.

If it is desired to employ the machine for cultivating purposes, the bearing-Wheel D is adjusted so as to be out of contact with the ground and the shaft H is adjusted so as to bring its wheels H above the plane of the cultivator-blades, to permit themxto enter the ground to the required depth, or said shaft is disconnected from the latches I, and given a free up-and-down movement in connection with its pivoted supporting-brackets to accommodate itself to the surface of the ground.

In moving the machine from one field to another the driving-wheel pawls are disconnected from the ratchets of the shaft H, and said driving-wheels are permitted to rotate freely on the shaft without affecting the other parts of the machine.

Various changes in the form and proportion of parts and details of construction can be made without departing from the principle or sacrificing the advantages of my invention.
