WHEELED CULTIVATOB.

li .escso lie it l-nown that. l, llowum M. l'lmnnav. a citizen oit the United States. and a resident ot South end, in the count)7 of Saint Joseph and State ot lndiana, have invented certain new and useiul lmprovements in ll'hceled tultivators: and l do hereby decare the Afollowing` to he a toll. clear. and exact, description oi the invention, such as will enable others skilled in the art to which it appertains to make and use the saine.

This in\.'cution relates to innlirovements in wheeled cultivators, this case beingr a division ot application tiled by nie on the ltth da)Y ot December. 1915 and designated bv Serial No. (37.231.

(')ne object ot in v present invention is to provide a scat construction 'tor cnltivators which may he easilv shifted laterallyY with slight, exertion on the part ot the operator. whereby the operator may be permitted readil)Y to view the plants being cultivated.

A\ 'further object is to provide simple and eli'icient means whereby the laterally-shiftable scat construction ma)7 be readilli7 adjusted. or he VFolded when the machine is operated as a walkingcultivator.

lVith these and other objects in view, the invention consists in certain novel features ot construction and combinations ot parts as hcreinat'tcr set forth and pointed out in the claims.

Divided and this application tiled March 23.

ol a rear arch axle, the respective members` T. T, of the latter being mounted in said tubular bar and in the hubs o'l' carrying wheels 8.

'.lhc pole 3 is provided with a rearward extension 9 (which may comprise two metal bars l0-ll secured to the upper and lower 'Faces ot the tongue and secured together rearivardl)Y 0i.' the tongue. as shown at l2 Fig. B) and with said rearward tongue cxtension, a Yfront a rch 13 is connected througrh the medium otl a coupling` 1l which is keyed to said arch and pivotall)Y connected with the tongue extension 9, as shown in Fig. The lower ends oi the respective men'ibcrs ot the Vfront arch lf3 are made with laterally projecting' horizontal arms l5. lor attachment of cultivator `Qjang frames 1V. ln eiiecting' such connections between the gang trames and the arms o't` the front arch. couplings 1T are mounted on said arch. arms and with these coupling-s. the gang trames are pivotall)Y connected bv vertical pivots as shown at 1S. The pivotal connection between the gangT trame and coupling` is located near one end oi the latter and a rod 19 is attached to said coupling' near its other end.the rear end of. said rod being' threaded and adjustahly connected with a bracket Q0 secured to and projecting laterall'v trom the lrang 'trame.---such construction affording means t'or adjusting the gang 'trames laterally.

An evcner bar 2l is pivotallv connected between its ends to thel tongue 3 and with respective ends ot' said bar7 depending draft eoualizers 22 are pivotallv connected. These vertical equalizer bars are adapted tor the adjustable attachment ot swingletrees 2?). and at their lower ends. said equalizer bars are connected with the arms of the front arch h v means of suitable links Q4. Brace bars are attached at their forward ends to brackets Q6 mounted on the tront arch arms and extend rearwardly and upwardly therefrmn. the rear ends of said brace bars being: attached to the brackets G at the rear end oiE the main frame.

T emploi7 a seat trame comprisingl flat bars o? 67 disposed edgewise and connected vat their forward converging ends by a bracket. 68. said trame bars beingT separated somewhat forwardlv of their rear ends by a cross bar k-which latter is mounted over the,

arch axle as presently explained. rIhe rear ends of the bars 67 are bent downwardly to form depending arms 7 0, each having a se ries of perforations 71. The forward ends of seat arms 72 are pivotally connected with the bars 67 forwardly of the depending arms 7l and adjustablyY support a seat 73. The seat arms and the seat are adjustably supported by bolts 74 passing through any of the series of perforations in the depending arms 70. By means of this construction the seat may be adjusted vertically to accommo` date a particular operator and enable him te readily reach the stirrups 66 en the cultivator gangs. This construction also permits the seat to be folded over the machine rout of the way when adjustment of the through the boss 76 and is provided at its lower end with a head countersunk into the bracket 7 5,-the upper end of said bolt being threaded to receive a nut 78, between which and the upper ends of the bars 76 and hub 77, a washer 79 is disposed. The cross bar 69 is made in .its under side with elongated grooves or runways 80 for antifriction balls 81 and the upper face of the bracket 75 affords trackways for these balls. Stops 82 are provided on the bracket to prevent escape of the anti-friction balls.

The bracket 68 is provided in its rear por tion with an elongated slot 83 in which a roller 8l enters, said roller being carried by a pin 85 projecting upwardly from the tongue extension 9, and in this manner the forward end of the seat frame is loosely connected with the rear end of the tongue.

The bracket 68 is provided at its forward end with upwardly projecting arms 86 braced by a spreader 87, and in said bracket, (at thelower ends of the arms 86)., a roller 88 is mounted. This roller is adapted to run on a transverse bar 90 (disposed above the same) when the seat frame is swung laterally on its pivotal mounting. The transverse bar 90 is connected with the main frame bars l, by means of brackets 91, and the respective end portions of said transverse bar are connected, by means of rods 92 with Vbrackets 93 on its lower horizontal arms of the front arch 13, as shown in Figs. l and 2.

' It will be understood that when the operator is sitting upon the seat 7 3, his weight will be sustained upon the arch axle through the intervention of the antifriction balls, and that the roller at the forward end of the pivoted seat frame will press upwardly against the transverse bar 90. When the op crater forces the seat to the right or left, the cross bar 69 will pivot on the bracket 75 and the balls 8l will roll on the trackways afferded bythe cross bar 69 and bracket 75, while the roller 88 will rub on the transverse bar 90. Such construction reduces frictional resistance and renders easy the shifting of the wheels and shovel gangs for cultivating plantsnot planted in straight lines, and by disposing the bars of the seat structure edgewise, the operator is enabled more readily to see the plants being cultivated.

A hook link 94 may be attached to one of the brackets 91and adapted to be connected with the front arch for locking the same against side movement, when the machine is being transported.

Various slight changes might be made in the details of construction of my invention without departing from the spirit thereof. or limiting its scope and hence l do not wish to restrict myself to the precise details herein set forth.

Having fully described my invention what l. claim as new and desire to secure by Letters-Patent is l. The combination with a wheeled frame, and a cultivator gang connected therewith, of a seat frame including a transverse bar a horizontal bracket secured to the wheeled frame, means pivotally connecting the transverse bar of the'seat frame and said bracket, anti-friction devices between said transverse bar and bracket, a forward transverse bar secured to the wheeled frame, and aroller carried by the forward end of the seat frame and adapted to run on the under side of said forward transverse bar.

2. The combination with a wheeled frame and a tongue, of a pivotal connection between said forward portion of the wheeled frame and tongue, a seat frame pivotally mounted between its ends on the wheeled frame, a loose connection between the for ward portion of said seat frame and the tongue, a cross bar carried by the forward portion of the wheeled frame, and means on the forward portion of the seat frame movable on the under side of said cross bar.

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.

EDWARD M. HEYLMAN.
