V1 is a vertical cross section taken on line VIVI, Fig. V. Fig. VII is a vertical cross section taken on line VIIVII, Fig. V. In the accompanying drawings: 1 designates'one of a pair of ground wheels of a seeding machine, and 2 the axle that is mounted in'said wheels, The axle supports a frame which includes longitudinal members 3, a transverse beam 4 located intermediate-of the forward and rear; ends of the longitudinal-members and the forward tie bar dwhich-rinitessaid longitudinal members. 6 arehangerarmsprojecting downwardly 8 is a furrow opener, the forward endof. which is connected'by draw links 9 to the hanger bar 7 through the medium of a consnection block 10' fixed to said bar. The furrow opener sup orts a seed chute 1-1 into which grain. isthrough a tube 12. llhe seed box 13 hasthe utility, in addition :to its service as-a eont'ainer for seed, of serving as'a seat for the operator of the machine while driving the team by which the seedingimachine is drawn over the ground in which seed is to be planted.

1 1. designates a draft tongue, to the rear portion of which is secured a pair-of side bars 15, which terminates beyond the rear end of the on no, as seen most clearly in Figs. HIv and 16 are a pair of connecting barsthat are pivotally. united at their forward ends to the rear ends of the side bars-15 byfia coupling bolt 17 The connection bars ere also united to, a member to be hereinafter more particularly referred to. To provide-for the t raft tongue being susceptible of a forward and rearward movement relative to the frame of the seeding machine, said tongue is supported .b s pair of -U-shape' rocker members 18'ari --19,-both-of;which-have arms that embrace the draft tongue as clearly. shown in Figs. V to VI inclusive. Th rocker member 18 is provided with intles 20 which are loosely mounted in brac ets 21 secured to the crossbe'am 4 of theframe'of the seeding machine, and the arms-of this rocker memberare loosely connected to the draft tongue by a pivot bolt 22 which-extends through the arms of the draft tongue and which is provided ,at one end with-a stem 23 that is of service in a manner'to be hereinafter ex lained. The rocker member 19- is provide with pintles 19 that are loosely mounted in brackets 24: secured to the tie bar 5 of the seeding machine frame, and the arms. of this rocker -member are pivotallyconnected to the draft tongue by a pivot bolt 25.- It will be seen from the foregoing description, that the draft-tongue is so su ported by the rockermembers-18 and 19 t at it is susceptible of forward and rearward movement when it is drawn forwardlyby a team of draft animals-hitched 'oppcd from a seed box 13 animals are backed relative to. the seeding machine.

26 cles1gnates a rock shaft that is loosely mounted in the rear portion of the side memthe furrow opener, as-seen in Figs. I and V. 3'

29 designates a segmental ratchet rack which is provided with a series of ratchet teeth 30 located at the edge of the rack and extending fearwardly from its rearend and also with a notch 31, located near the forward end of' the rack in the edge thereof. The ratchet rack is secured to the rock shaft 26 by a clip member 32 formed integral with the rack and a clip member 33 which opposes the clip member 32 and :is united to it by bolts 34 which serve to hold the ratchet rack in a rigid position upon the rock shaft 26.

35 is an-arm extending downwardly-from the clip member 33, as seen in Figs. I and IV. 36 is a hand lever fixed to the ratchet rack 29 and to which is pivoted a grip arm 37 that has united to it a pull rod 38, having a function to. be hereinafter mentioned. I

The draft tongue 14 is pivotally connected at 39 to the ratchet rack 29 by means of a bolt which passes through the rear end of the connecting bars 16 and said ratchet rack, It

will be readily understood that when the ratchet rack is in a free condition-and the draft tongueis in a rear-positiomas illustrated in Fig. IV, a pull may be exerted upon the draft tongue that will cause it to be drawn forwardly to exert a pull upon the ratchet rack and rotate the rock shaft 26 in a forward. direction with the result of causing the arm 2?.to be moved downwardly and act to lower the furrow opener 8 that is connected to said arm to and into the ground. It will also be understood that when the draft tongue is moved rearwardly, it will act upon the ratchet rack and by rotating therock' shaft in a backward direction cause the furrow npener to be lifted from the ground.

The ratchet rack 29 is controlled by means which will now be described. 40 is a double arm pawl member that is pivotedat 41 to a bracket 42 secured to the frame of the seeding machine at a point in front of the ratchet rack. This pawl member is provided with an upwardly extending pawl 43, having a tooth 44 that is adapted to engage the teeth 30 of the ratchet rack, and to enter the notch 31 in said rack, as illustrated in Figs. 1 and IV. The pawl member 40 has a'iower arm 45 which extends rarwardly to a position beneath the rock shaft 26. 46

is a hand lever pivotally mounted in a bracket strap 47 fixed to the draft tongue 14 and pivoted at 48 to the frame of the seeding machine, as seen in Fig. I. The

rass? to which is attached a pull rod 50 that leads to a chain 51 which passes around a sheave 52 (see Figs. I and VII) supported by the hand lever 46 and which is united to a connecting rod 53 that leads tothe pawl arm 43. lVhen the handle of the hand lever 46 is grasped by the operator of the seeding machine while riding upon the machine and the grip arm 49 is moved to said handle, the pawl '43 is released from the ratchet rack 29 so that said ratchet rack is freed, and the draft tongue is rendered serviceable for'the lowering or lifting of the furrow openerin the manner previously stated. In the actuation of the pawl member 40 to move the pawl 43 out of engagement with the ratchet rack, the lower arm 45 of said pawl member. serves to limit the degree of movement of said pawl member, due to its.risinginto con tact with the rock shaft 26. It should be here noted that the pawl 43 acts by'engagement with the teeth 30 of the ratchet rack to restrain said rack from m'ovement when the furrow opener has been lowered into the ground to the desired depth. The pawl also acts to hold the rack bar from movement when the furrow opener is in an elevated position and out of service, the engagement between the pawl and rack at this time being accomplished by the entrance of the tooth of the pawl into the notch 31 in the rack. The hand lever 36 serves as a means for actuating the pawl member 40, when the operator of the machine is walking upon the; ground at the rear of the machine, in

order that the draft tongue maybe brought into operation for furrow opener lowering and lifting action, and the actuation of the pawl member in this instance is accomplished through the medium of the grip arm 37 and connecting rod 38 carriedby said hand lever and a connecting chain 54 that unites said connecting rod to the lower arm 45 of the pawl member. 55 is a retracting spring that connects the pawl member 40 to the frame of the seeding machine and through the medium of which the pawl arm of said'member is maintained in engagement with the ratchet rack 29 when the pawl member is at rest. 56 designates an assistance spring that is connected to the draft tongue 14 by an eye bolt 57 seated in said tongue and by a link 58 to the arm 35 that is associated with the ratchet rack 29.

This spring serves as a means for actuating the ratchet rack in connection with the draft tongue and the other parts associated therewith, in order that the furrow opener may be more readily elevated from the ground.-

The hand levers 36 and 46 serve as means ing the ratchet rack in a corresponding direction and raising the furrow opener during the rearward rotation of the rock shaft 26. The pawl arm 43 is then released and its tooth 44 engages in the notch 31 of the ratchet rack and acts to hold said rack from movement, and the furrow opener in its uplifted position. When the operator is walk ing upon the ground and desires to elevate the furrow opener, he grasps the handle of the hand lever 36 and the griparm 37, thereby releasing the pawl 43 from the ratchet rack 9.9, after which he imparts a downward pull to said hand lever. and thereby moves the ratchet rack rearwardly until the furrow opener is elevated, after which the pawl arm is released toengage the-ratchet rack in a manner previously stated. When the operator has moved the hand lever 36 to the osition in which it appears in full lines,

*ig. IV, the furrow opener is in elevated position. \Vhen said hand lever is moved to the position seen in full lines, Fig. I, the furrow opener is in lowered position and rests upon the ground. When the hand lever is in the position indicated in dotted lines, Fig. IV, the furrow opener is in the position assumed after it has been forced into the ground during seed planting operation.

For the purpose of restricting the degree of movement of the draft tongue, and consequently the degrees of movement of the ratchet rack and the. other parts associated with, and having connection to said ratchet rack, including the furrow opener, I utilize a gage bar 59 that is loosely fitted to one of the pintles of the forward rocker member 19 by which the draft tongue 14 is supported. This gage bar extends rearwardly from its point of attachment just mentioned and it is provided at its rear end with a hook (it) and contains a plurality of pin holes 61, seen in dotted lines Fig. I, which are located intermediate of the ends of the bar. 62 is a catch movably mounted on the gage bar and provided atits rear end with a finger 63. This catchis adjustably held to the gage bar by a pin or bolt 64 thatis inserted into the I catch and into either of the pin holes in said gage bar. The rear portion of the gage bar 59 rests upon the stem 28 of the pivot bolt 22 which connects the rocker member 18 to the draft tongue. \Vhen the draft tongue is drawn forwardly in the act of lowering the furrow opener to and into the ground, the catch 62 serves as a means for restricting the degree of forward movement of said tongue and consequently the de ree to which the furrow opener is lowered,,t is beingdue tothe stem 23 coming in contact with the finger of the catch 62. It will be seen that due to the catch being adjustably mounted upon the gage bar, the depth to which the furrow opener is caused to enter the ground may be varied, as may be desired. The hook at the rear end of the gage bar serves as a means for limitingthe degree of rearward movement of the draft tongue, due to the stem 23 coming in contact with said hook, when the draft tongue is moved rearwardly. to the proper extent.
