To all whom it may concern :7.

Be it known thatI, EnwprBAYLIss, of Massillon, in the county of StarkandStateofOhio, have invented certain new and: useful 1m provements in Wheel-Harrows and Cultivators, of which-the following is a full, clear, and exact description.

. My invention relates to that class of wheelharrows having harrow, cultivator, or pulverigar disks arranged in gangs upon horizontal s afts.

. 1 "The object of -the first part of myinvention is to adapt the gangs. to follow or conform to uneven surfaces over \which they pass, which. end I attain by combining wheel or disk gangs with a transverse bar or main frame by means of interposed swiveling hinge connections, which allow the gangs to play freely relatively to the frame.

The object of the nextpart of my invention is to adjust the wheel-gangs-relatively to the ,line of draft without interfering with their vibrations on their hinge-connections, which end I attain by combining a main frame or main transverse bar, a tongue connected therewith, wheel or disk gangs united to the main frame by interposed swiveling hinge-connections, and an adjustable connection between the tongue and wheel or disk gangs, which latter connection allows their angle relatively to the line of draft to be varied without interfering with their vibratious'on their hinge-connections.

The object of the next part of my invention is to limit the oscillation of the wheel gangs or disks on their hinge.-connections, which end I attain by combining a main frame or main transverse bar, wheel or disk gangs connected therewith by interposed swiveling hinge-connections, and chains or stops, to limit the vibrations of the gangs relatively to the main frame.

My invention further consists in combining,

a 'in a 'wheel-harrow, a main frame or-main transversebar, a tongue, a ,drivers seat, wheel or disk gangs connected with the main frame by interposed swiveling hinge-connections, and

adjustable connections between the gangs and tongue, to adjust the angles of the disks relatively to thelino of draft, and'to limit their vibrations relatively to the main frame.

T e ne meme i s m R m t method of mounting the barrow-disks upon rotation, which end I attain by combiuin g harrow-disks having polygonal sockets-(oran equivalent adjusting device) with interposed spacing-ferrules constructed with projections engaging said sockets, as hereinafterset'forth.

mounting the disk-gangs in their bearings; Its objects are to prevent wear of the bearings briqation, which ends I attain by mounting the gang-spindles in hanger-bearings recessed to receive lubricating material and friction-washers, which take the end thrust occasioned by the inclination of the spindles to the line of draft. I

Figs. 7 and 8 show detail views of the disks and their locking devices.

sents a main frame, or its main. transverse bar,

pole or tongue, G, is pivoted. Instead of bolting the gang bars or frames D 1) directly to the'under face of the main frame or main transverse bar A, or simply connecting them therewith by a vertical pivot, to permit theii angular adjustment relative to the path of the class of machines,- I combine them with said connections shown in the drawings as consisting of ang e-irons or hinged plates E E E, united'with the frame-bar by a vertical pivot, whiclilpermits them to turn horizontally-to vary the angle of the gang-bars relative to the path of the machine, as above explained, and I also connect said hinged plates to the their spindles, in order to insure a-uniform' The next part of. my invention relates toor gang-spindles and insure their proper lu-L thereof; Fig. 3, a side elevation; Fig. 4, a rear.

their hinge-connections Fig. 5, a vertical cen- In the accompanying drawings, A repreand B a longitudinal bar'- or bars, to which a machine, as heretofore has been usual in this frame or bar by means of swiveling hinged acting as a stop to limit 2 I an? gang-bars by means of a horizontal transverse bolt or pivot, e, on which the gang-bars rock vertically to conform to the uneven surface 'of the ground over which they pass. v

Fig. 4 shows modifications of the hinge-connection abovedescribed. E represents a straphinge, one leaf of which is pivoted or bolted to the main frame or bar A; and the other to a block, 0, on the gang-bar. The hinge E is shown'as formed of two eyebolts, one secured in the frame-bar and the other in the gangbar, thus forming a the swiveling movements above described.

The gang-bars areremoved by their interposedhinged connections sufficiently far from the frame-bar to permit of their required vertical vibration relatively thereto. The hingeconnections may be adjusted transversely relatively to the machine by securing their pivot in any one of a series of holes, a, upon the frame-bar, and the gang-bars are likewise capable of a similar adjustment relatively to' their hinges by means -o'f a series of holes in them,'in any one of which the pivot 9 may be inserted. By means of these adjustments the strain of the wheel-gangs on either side of their-pivots or axis of oscillation may be adjusted, balanced, or varied.

The hinge or piv'otal connections between the frame-bar and gang-bars are preferably located at a point nearer their outer than their inner ends, so as to throw the greater strain or drag upon the in her end of each gang. The tendency thus" created for the inner ends to drag behind their outer ends is counteract d by means of an adjustable'connection between the inner, end of the wheel-gangs and the tongue, which'connectio'n is shown as consisting of a draft-rod, F, connected with each gang-bar, near its innenend, by an eyebolt, f,-

and 'by'a similar connection between the forward end of the draft-rod and an eyebolt, f, capabie'ofadjustment backward or forward in one of aseries of holes, f, on the tongue, by whichlmeans the angle of the gangs relatively to'the path of the machine may be adjusted as desired, I Adjustable links or. chains d d, attached at one end to the gang-bars and at the others to the frame-bar A or tongue 0, serve to limit the downward movement of the ends of the gang-bars, the frame-bar itself their upwardmovement.

The chains may be lengthened or shortened by hooking difl'erent l1nks into hooks d, to limit the flexibility of the disk-gangs to 'suit the ground over which they may be passing,

and to prevent the gan gs from turning too far ontheir horizontal pivots in turning corners, &c.

The ends of the spindles I upon .which the disk-gangs revolve screw into journal-bearings or nuts J J which are mounted in hange'rs G depending from the gang-bars D; and as the disks shown in the drawing are dished, with their concave sides turned towardthe center of the machine, and as the inner end double joint permitting of inner of each gang (inthe construction shown) is arranged to travel somewhat-in advanceof its outer end, the disks revolve in lines oblique to the line of draft, and tend to gather and throw the soil inward. It consequently bears against the concave sides of the disks, pressing their spindles hard outward int'n recesses or boxes in the outside hangers G. This pressure, in the present form of construction, causes the hangers soon to wear through and. need renewing.

My improvedconstruction for obviating this objection is shown in Fig. 5, the box being formed with a recess, 9, cored out at its closed end, of a diameter greater than that of itsopen end in which latter the journal-bearings of the spindle fit loosely. The recess 9 serves the twofold purpose of holding oil for lubricating the end or journal-bearingof the spindle I, and for the reception of two or more solid leather disks or washers, i, made to iit loosely in the recess, but so large as to pass through the open end of the box, only with considerable pressure. This, insures their .always remaining in place. These washers take the pressure off the spindle, and being constantly oiled, owing to the oil-receptacle, prevent the wear referred to above. Y

The inner pendants or down-hangers G'of each gang are constructed with a divided bearing,'each half of which is cast with a central groove, and the lower half with a reservoir,- the former for thereoeption of a collar on the inclosed thimbleand the latter for the reception of oil to keep the journals lubricated. The collar t serves to relieve the end thrust and to take the wear off the shaft, and, being thus inclosed, is protected from dirt and grit, to which the ordinary wearing-surfaces of this class of machines are exposed.

The harrowadisks H have a series of perforations, h, arranged in a circle around the 'spindle. The hubs 7: of the spacing-thimbles' K are provided with spurs or teats k, which enter into one of the series of perforationsabove mentioned in the disks, and the entire series of disks and thimbles, being clamped together by the usual nuts J J, insure uniform rotation of the disks.

- Instead of being perforated, the disks may have upon each face polygonal sockets, consisting of a raised head or flange, h, (concentric withv the spindle 1,) large enough to receive the ends of. hubs, or ferrules made of corresponding form, (but somewhat less in diameter to'allow for maccuracies in casting,) but at the same time large enough to insure the rotation together of the disks and tbimbles'. The nut which secures the end or last ferrulein place should be enlarged sufliciently to rest socket.

By the, employment of the series of perforations h, pins or polygonal sockets, and links as above described, the disks may be adjusted relatively to each other and to the spacingthimbles to-compensate for. variations in warpe on the face of the bead forming the ingof parts in cooling, and also for inaccuracies in molding. v v

The outer ends of the frame-bars may be provided with boxes to receive weights for increasing the efliciency of the barrow, or for adaptingit to the character of the ground on which it is used. Y

A drivers seat, M, is shown as mounted upon a standard, m, secured upon the tongue or its extension centrally over the frame-bar A.

When used as a cultivator, thedisk-gangs may be separated either by moving transverse ly the' hinge-connections in the main frame or in the gang-planks, or both, so as to straddle the row of corn or other crop to be cultivated; and, if necessary, shorter gangs can be used,

, consisting of a less number of disks, to suit the difl'erent widths between rows of diflerent kinds of crops. v

' By supplying shorter gang-planks and rods for the lesser number of thimbles and disks, themanufacturer may, at this slight extracost,

furnish a combined pulverizer and cultivator,

. as disks, thimbles, nuts, hangers, 8m, can be comngggfoboth. I r A ing attachment of any usual or preferred construction may be applied in the manner usual in this class of machines.

I claim as of my own invention- 1. The combination, substantially as hereinbefore set forth, of a main frame (or main transverse bar) and wheel or diskgangs connected therewith by interposed swiveling hingeconnections, which permit the gangs to vibrate freely relatively to the main frame to conform to uneven surfaces over which they pass.

2. The combination, substantiallyashereinw before set forth, of a main frame, (or maintransversebar,) a tongue connected therewith, wheel or disk gangs united with the main frame by interposedswiveling hinge-connec tions, and an adjustable connection between the tongue and wheel or disk gangs, whereby. the angle ot the gangs relatively to-the line of draft may be varied without interfering with their vibrations on their hinge-connections. s

3. The combination, substantially as hereinbefore set forth, of a main frame, (or' main transverse bar,) wheel or disk gangs connected with the main frame by interposed swiveling hinge-connections, and chains or stops, for limiting the vibrations of the gangs relatively to the main frame.

4. The, combination, substantially as-hereinbefore set forth, of a main frame, (or main transverse bar,) a tongue connected therewith a drivers seat, wheel ordisk gangs connected with the main-frame by interposed swiveling hin ge-connections, and adjustable connections between the gangs and tongue, to adjust the angles of the disks relatively to the line of draft, and to limit their vibrations relatively to the main frame. 4 1 1 5. Harrow-disks provided with polygonal sockets, or an equivalent adjusting device, in combination with the spacing-ferrule construct-- ed with projections interlocking with thedisksockets, substantially as shown, and for the purposes described.

6, The combination, substantially as hereinbefore set forth, of gang-bars, hangers havin g bearin gs enlarged atone end to constitute lubricating chambers, friction washers inclosed insaid lubricating-chambers, and diskgang spindles inclined to the line of dra whereby wear of the spindles is preven and lubrication insured.
