WILLIAM S. GRAHAM, F CANTON, iI-LINGIS, ASSIGNOR TO PARLIN AND ORENDORFF COMPANY, OF CANTON, ILLINOIS, CORPORATIQ N 0F ILLINOI$.

CULTIVATOR.

' Canton, in the county of Fulton and State of Illinois, have invented certain new and useful Improvements in Cultivators, of which the following is a specification, reference being had to the accompanying drawings. My invention relates to cultivators, and its object is to provide a new and improved construction by which'the wheels may be angled and the gangs shifted laterally simultaneously by the same lever movement, by

which the gangs may be raised or lowered either separately or 'in'pairs, by which the wheels maybe shifted backward relative to the frame simultaneously with the raising of the gangs in pairsby means of a single layer, by which the wheels may be automatically locked against angling and the gangs against lateral. movement when the gangs are raised or when the wheels are shifted to their rearmost position, and by JWhlCll the wheels may be shifted laterally 'for diflercnt widths between the rows to be cultivated." I accomplish this object by the means shown in the drawings and herein after specifically described. That which I believe to be new will be set forth in the claims. I 1 v In the draw1ngs:*l l1gure 1 is a side elevation of a cultivator embodying my improvements. with one of the wheels removed for the sake of'clearness of illustration.

lteferringto the drawings :20 indicates cariying wheels mounted upon spindles Qt. llachsspindleQl is provided with a vertical portion 22 (see 8). which, at its upper end, is provided with a torward ly-projecting portion 533 (see Fig, 5), the three parts being formed ii'iteg'ral. Each spindle member 21 is rcvolubly mounted in a vertical sleeve 24., said sleeve being cut away for the greater portion of its length at its front side 'to enable the integral spindle member to be inserted.

As shown in Fig. 5, the lower end of the sleeve that is not cut awayis enlarged to receive the lower end of a block (see Fig. (3) which is used to take the place of the cut-out portion of the slceye to hold the spindle ll'lQl'l'lllQI' 21 in position, said block being secured in place at its upper end by a bolt passing through it and through loss 26 on the sleeve. At the pointwhere the torwardly-projccting portion 23 emerges from the sleeve 24, sufiicient play is. provided to enable the part22 to be rotated to a limited extent in the sleeve 24. by the lateral movement of the front end of the part 23, thus angling the wheels relative to the machine. as will 'bereadily understood.

As shown in Fig. the sleeve it is part oi a bracket comprising also a ho; izontal bar 27, a diagonal bar 28. and horizontal transversesleeves 21) and 30, one of suchbi'avkcts being provided at each side of the machine, as shown in Fig. 4.. 31 indicates a tubular bauextcnding "from side to side of the machine. each end-being inserted in one of the sleeves 30 so as to slide treelyiherein. 32 indicates rods. one at each side of the machine, each adapted to slideircely at its inner end in said tubular bar 3l and each bqdted or otherwise secured. at its outer end viding for a free and easy movement of each bracket laterally relative to the tubular bar 31, as will be seen. The rod 32, tubular bars 31, spindle members 21 and the brackets by which such parts are connected, constitute in effect a wheel-arch pivoted relative to the frame. 33 indicates two brackets one of which is securely attached upon each end of the tubular bar 31 by means of a wedge bolt 33 34: indicates hounds which are bolted at their rear ends to the brackets 33 and at their forward ends to the tongue 35, as shown inFig. 2. 36 indicates seat-supporting bars which are, by means of angle irons 37, secured at their forward ends to the crossbar 50 hereinafter referred to, extending rearwardly therefrom and resting upon the tubular bar 31. Secured to the rear ends of these bars 36 is a seat 38 of any suitable type.

As shown in Figs. and 7, the forward ends of the portions 23 of the spindle members are pivotally connected between two parallel transverse bars 39 whereby by movement of the bars 39 longitudinally of themselves the wheels may be simultaneously angled.

As best'shown in Figs. 13 and 1d, each of the brackets33 is provided on its rear and "lower side with a circumferential flange or rib 40. 41 indicates a block grooved on its front face to engage said rib &0. These blocks ll are adapted to be bolted to the horizontal portions 27 of the brackets which connect the wheel spindles to the frame of the machine and) thus hold said brackets against lateralmovement, at the same time permitting a limited swinging movement of the bracket relative to the tubular bar 81 upon which the brackets 33 are fast.

As shown in Figs. 5 and 8, the bars 39 are provided with a series of holes through any one of which the bolt that connects the portions 23 thereto may be passed, and the hori zontal port-ions 27 of the brackets have a like number of holes through the corresponding one of whichihe bolt which secures the block 41 in position may be passed. By this means the wheels may be readily and .quickly shifted laterally for understood.

rows of different widths, as will be readily (see Fig. 4) having out-turned horizontal 4-4: indicates yokes revolnloly mounted upon the horizonta-l portions 43, attached to which are shovel beams 45 of any approved type, carrying shovels 46. 47 indicates sleeves mounted upon the horizontal portions 43 between'the arms of the yokes Secured at their lower ends to the sleeves 47, each being pivoted between ears formed on one of the sleeves,

itch pivoted between formed on 42 indicates the shovel arch two push hars 48, the upper ends or" the bottoms of the braclwls 33, as shown in Figs. 5 and 13. i9 indicates rods hooked at their lower ends in cars on said sleeves ll, as best shown in Fig. 1, and hooked at their upper ends in suitable openings in the transverse L-shaped bar 50 which is bolted at its center to the tongue and secured near its ends to the hounds 34. These two parts -18 and 49 which support the lower ends of the arch 4?. permit lateral movement of the arch. Upon the upper horizontal portion of the shovel. arch 42 (see Fig. is a split sleeve 51 which is adapted to be clamped securely inplace by means of abolt. Extending rearwardly from this sleeve 51 is a short arm 52 to which is attached bymeans of a hori- Zontal pivot a plate This plate is socured at its rear end between the transverse bars 39 by bolts, the distance between which bars 39 is sullicient to provide for some little play between the plate and the bars 39 so that they may be either held in alinement in their normal position or may be angled slightly relative to each other when the .whecls are shifted backward in the frame when the gangs are raised in pairs, us hereinafter described.

it will be readily understood from the above description that when the bars ll!) are shifted longitudinally of themselves in angling the wheels, as above described, they will carry with them to one side or the other of the machine the plate 53 and arch 51-52. which in turn will throw the front ends oi the shovel beams (oi-respondingly to that side.

Revolubly mounted upon the tubular bars 31 and depending therefrom (see Fig. 8), are two brackets 54: secured against lateral movement by'collars 55. Bolted to these brackets 5% are two foot-levers 5G-57, each provided with a treadle 58. Each bracket 54 is provided with a perforated lug 59 on its front face, intowhich the rear cud of a push-bar 60 is hooked, the front end of which bar 60 is provided with an opening through which opening and through suitable openings in the bars 39 at some little distance farther toward the side of the 1nachine than the bracket 54 is passed a boltv or rivet.

From the above description, it is apparentthat by pushing the footlever 57 forward the bars 39 are caused to shift to the left in Fig. 7,'thus carrying the arch 42 to the left and at the same time angling the wheels to carry the machine to the left. as hereinabove described. Pressure upon the foot-lever 56 serves thereupon to return the parts to the normal position (shown in Fig.

4), and further pressure upon the foot-lever with an ear 63 which is bolted to the transverse bar 50.

64 indicates a bracket (see Fig. 12) which is provided with a boss 65 adapted to fit and rotate in, a circular opening in the bracket 61,- passing centrally through which boss is one centrally through a similar circular boss on asleeve 67 which fits and rotates in a circular opening in a bracket 68 which is bolted to the hound 34 at the opposite side of the m-achinefrom the bracket 61. The bracket .c with a hahdle 64 and sleev'e67 are bolted rigidly to the rock-shaft 66, so that the bosses are held firmly in contact with the circular openings in the brackets 61 and 68 so as .to rotate therein, the rock-shaft also being thus r0- tatable in said brackets.

69 indicates two brackets non-rotatably secured on the rock-shaft 66.

70-71 indicate levers which are bolted to brackets 72 that are pivotally mounted on bosses 69 formed integral with said,

brackets '69, each of which levers is provided portion 7 3, a latch '74, springactuated plunger 75, and rod 76 connecting the plunger and latch, which. plungers are adapted to engage the teeth of racks 77 .car-

' separately at any at their upper ends against collars 85 which ried by said brackets 69 to set the levers desired position relative to the brackets. Each of the brackets 7 2 has on its front face a short distance above the j pivot point of the bracket 72 upon the bracket 69 a perforated lug. 78 to which is,

attached one end of a coiled spring 79 the other end of which is 'adjustably attached to an arm 80 depending from the transverse bar 50, said spring tending to hold said bracket 72 in its forward'turned position.

' On the ear face of each bracket 72 is a perforateo lug 81 to which is attached the upper end of a pull-rod 82. The lower ends of. the rods 82pass through holes in brackets 83 secured upon the gangs 4.5, being slida ble therein but prevented from withdrawal therefrom by heads 82 on their lower ends. Upon each rod 82 is located a compression spring 84 which bears at its' lower end against the bracket 83. These springs bear are secured by set-screws upon the rods 82, by which construction-the spring may be caused to press more-or less heavilyupon' the gangs as desired.

From the above description, it will be seen that when either of the levers 76er- 71 is moved forward, through the medium of the pull-rod 82, the gang connected tosuch lever is raised, such raising of the gang be-. ing assisted by the pull of the extended spring-79, the strength of, which canbe adend of asquare rock-shaft 66. 'The other end of.the rock-shaft 66 passes justed, as above described, It will also be seen that when the lever is moved backward to permit the gang to be in its lowered p'o sition, the spring 84 serves to hold the gang yieldingly strength of this-spring also being adapted ,to be adjusted, as described.

Coming now to the means for raising the gangs in pairs and for shifting the wheels backward and forward relative to the frame,

85 indicates a leverbolted to the bracket 64 whereby the rock-shaft 66 is adapted to be turned. The lever 85 is provided with the usual handle portion 86, latch 87, springactuatcd plunger 88, and rod 89 connecting the latch and the plunger.

' 90 indicates a flange on the bracket 61,.

provided with two notches which the plunger 88 is adapted .to engage to hold the lever in position,'as will be readily understood.

91 indicates arms depending from the bracket 64 and sleeve 67, to thedower ends of which are pivotally attached heads, 92 into which are screw-threaded the front ends of rods 93, the rear ends of which are hooked in perforated lugs 94 on the front faces of the sleeves 241 From the above description it will be seen that when-the lever 85 is moved upward from the position shown in; ll 1, for example, the rock-shaft 66 will bero- .ta'ted clockwise in said figure, causing'the levers and 71 to mov forward, raisin-g both of the gangs 45, both of the springs 79 assisting in the operation. At the same time, through the medium of the.rods $13, the sleeves 24 and therefore the axles 21 will be moved backward relative to the frame so as to'compensatefor the additional weight of the gangs at the back part of the machine and to'maintain the proper balance It will be of the machine on the wheels. seen that if the lever 85 be moved upward while the machine is still in motion, the operation will be greatly assisted by the tendency of the wheels to stop and the con-' sequent backward pull upon the rods 93.

Each of the brackets 54 is ,provided with an arm 95 rising therefrom and provided at .its upper end with a'horizontal stud 96, extending over the seat-supporting bar 36 at that side of the machine. Asshown in Figs. 1 and 4-, when the gangs are in lowered position and the wheels are consein. the ground, the effective quently in their foremost position, the studs 96 are some little distance above the bars 36. When, however, the 'gangs are raised by means-of thfe leve ,85 and the wheels'are, as has been gescribediat the same time shifted'loackwar' re lative to the frame,- the. bars 39 are lowered and: shifted slightly backward, as se'err'by acomparisonof Figs; 1

and, 3, .c'ausinga corresponding change in position of the'push-rods 60 and. brackets ends of said blocks in position,

&

5st. The result is that each of the studs 96 is brought into contact with one of the bars 36, thus holding the brackets 5 1; against turning and preventing any angling of the wheels or lateral shifting of the gangs while the wheels are kept in their rearmost position, this result being attained automatically without any effort on the part of the operator. Any forward push of one of the foot levers, as 56, tends to lift its part 95, but also tends to cause the other lever 57 to move backward which is prevented. by the contact of the other part 95 .with the frame bar 34. I

So far as I am aware, no one in the art has heretofore provided means for automatically locking the wheels of this type of machine against angling or the gangs against lateral shifting when the gangs are raised, andgthe claims are therefore to be construed accordingly.
