Our invention is disclosed in connection diagonally arranged frame member 14:. The with a gang plow having a frame 10 includmovablepulley 44 is mounted in one end of ing two side members 11 and 12, a front an actuating lever 47 having a detent' 48 member 13 and a back member lextending adapted to engage notches 49 in the bracket diagonally between the frame members 11 i6 to'hold the plow in any adjusted posiand 12. This frame also includes supporttion. Aswshown in Fig.2, it is apparent in a bracket 46 which issecured to thethat by moving the hand end of the lever 47 downwardly, the movable pulley ll: will be elevated, thus raising the plow 35, and if it is desired to lower the low, the same may be accomplished by raising the lever 47. In like manner all of the plows 35, 36, 37 and 38 may be controlled manually for raising and lowering said plows individually. Securedto the frame is a series of spaced .vertically arranged guide members w between which portions of the respective plow beams are raised and lowered and prevented from being shifted laterally.

' For raising automatically in proper succession the individual plows, for example, at the end of a furrow, preparatory to turnmg, and for lowering automatically said plows in proper succession after a turn has been effected, the following meehanism is employed: Mounted upon one end of the shaft 18 (see Fig. 3), journaled in bearings 50 formed in a depending bracket 51, se-

cured to a frame of the gang plow, is a bevel gear 52 meshing with alarger bevel gear 53, secured to one end of a vertical shaft 54, journaled in the sleeve member 55 of.

the bracket 51. Secured to the upper portion of shaft 54: is a notched wheel 56, the notches of which are adapted to be engaged under certain conditions by a pawl member 57 having a roller 58 mounted in one end thereof. This pawl is pivotally mounted (see Figs. 1, 4:, 5 and 6) in a flanged portion 59 of a cam member 60, the latter of which is mounted loosely upon the verticalshaft 54. Secured to the pin 61, to which pawl 57 is fixed, is a collar member 62 having oppositely arranged ears 63 with depending projections 6t and 65 respectively, the former of which projections is'located in an elongated notch or opening formed by a projection 66 and a shoulder portion 67 of a dog 68, said dog being pivotally mounted loosely upon the lower part of'pin 61. .A spring 69 which connects an arm 7 0 on the projection 66 tends to swing the dog 68 inwardly into the position 'shown in dotted lines in Fig.

5. Said dog is normally held against the tension of said spring in the full line position shown in said figure, by either one of two adjustable fingers 71 and 72niounted upon a spindle 73 movably mounted in the plow frame and having ahandle or lever 74 held by a spring 75 to hold normally the fingers 71 and 72 in an upward-position to revent the dog 68 from swinging inwardly. ldy swinging the lever 74 upwardly, as

viewed in Fig. 1, and to the right, as viewed in Fig. 6, the finger 71 will be rotated or lowered out of the path of the dog 68 whereupon, due to the action of the spring 69,

the d0g'68 will be swung inwardly. During this inward movement the projection 66 of the do depen ing projection '64 of collar 62, ro-

68 passes into engagement with the tating said collar, shaft 61 and consequently pawl 57 into the full line position shown in Fig. 4c, the roller 58 of the pawl engaging one of the notches in the notched member 56. Due to the fact that this notched me1nber 56 is rotated by means ofitsconnections through'shaft 54, gears 53 and 52'and shaft 18 whenever the gang plow is in motion, the canrmember 60, with the pawl engaging a notch in the notched member 56, will be actuated to respectively and successively engage the arms 76, 7 7, 78 and 79 of the aetuated members 1-0, 41, 42 and 43 to raise the plows 35, 36, 37' and 38 respectively through the medium of their chains. After the power operated cam member has raised all;

in Fig. l. As the dog member 68 is being swung outwardly gradually, it swings freely upon the stem 61, imparting-no motion to the pawl member57 until the shoulder portion 67 of said dog member 68 moves into engagement with the depending projection 64 on the collar member 62 which is secured to shaft 61. At the instant said dog member engages said depending projection 6% a com pressed spring 81, held between projection 65 of collar 62 and projection 82 on the dog member .68, liberates suilieient force to snap the pawl 57 out of engagement with one of the notcheso of the notched member 56, whereupon further movement of cam member 60 is arrested. With the cam member 66 in dotted line position shown in Fig. 4, the

plows are raised. If it is desired to lower said plows automatically and successively, as, for instance, having turned preparatory to plowing in another direction, the hand. lever 7 1 is again swung to lower the finger 72 out of the path of'the dog member 68.

whereupon, as above explained, the roller 58. of pawl member 57 will be swung into engagement with one of the notches of the notched member 56. 'Due to the fact that said notched member 56 is continuously re tating whenever the gang plow is in motion, the cam member will be rotated farther in a clockwise direction successively passing out ofengagement with the automatically actuated members 40, 11, 42 and l3, permitting the plows35, 36, 37 and 38 to successively drop, due to their own weight, said automatically actuated members 40, 41, 4-2 and. -13 being limited in their movements by stops 85. with like manner, after the cam member has passed out of engagement with said automa tically actuated members 40 to 43 inclusive, the pawl 57 will be thrown out of engagement with the notched member by' the cooperation of the dog member68 and finger 71 It is apparent 'from the above that theintervals of operation of said plows through v the automatically actuated members 40, 41,

42 and 43, the plows will all be raised in a manner so that the end of the furrows made 'by the individual plows will be in a line perpendicular to the line of draft, plow ei'ng raised first, then successively plows 36, 37 and 38. In the same succession the plows will be lowered, the beginning of the furrows made by saidplows being in a line perpendicular to the line of draft. With the plows all sunk in the ground and in the operation of plowing, it will be seen that the depths of the plows may be controlled manually and individually by operating the hand levers 47 which effect a movement of the plows through the pulleys 4a and and the chains 39. It is to be observed that said pulleys and chains are used both in the automatic and manual operation of the plows. With this simple arrangement the plows may be raised and lowered automatically at will, and the'depths of the plows manually controlled to meet the requirements. For instancepif an obstruction of some kind is in the path of any one of the individual plows, that particular plow could be raised out of the ground without raising all of the plows, and then lowered again.
