CULTIVATOR GANG-PLOW.

SPECIFICATION forming part of Letters Patent No. 506,556, dated October 10, 1893.

Application led May 13, 1893. Serial No. 474,141. (No model.)

To all whom it may concern.-

Be it known that I, ALMEEON S. SEELEY, a citizen of the UnitedY States, residing at Everett township, in the county of Newaygo and State of Michigan, have invented a new and useful Cultivator Gang-Plow, of which the following is a specification.

My invention relates to improvements in gang-plows or cultivators, and the objects in view are to provide a machine of this class so constructed as to provide for a simultaneous or individual raising vof the plows contained therein; to provide for an adjustment of the frame and tongue and for the level running of the machine.

' Various other objects will appear in thefollowing description, and the novel features thereof will be particularly pointed out in the claims.

ReferringV to the drawings-Figure 1 is a perspective view of a plow constructed in accordance with myinvention. Fig.2 is a vertical longitudinal sectional view thereof. Fig. 3 isa rear elevation. Figet isa detail in perspective of one of the plow beams.

Like numerals of reference indicate like parts in all Athe figures of the drawings.

In. the practice of my invention I employ a substantial square frame, the same consistface with a vertical dovetailed recess 4, and

' ing ground-wheels.

the same diameter.

in each recess there is located a`dovetailed standard 5 from the outer face of each of which extends a stub-axle 6, said axle carry- The standards 5 may be adj usted, that is, they are secured by suitable devices. In the present instance, and merely as one way, I have shown binding bolts 7 for this purpose. The wheel at the left of the machine is preferably greater in diameter than that at the right, for the reason that the former travels in the plowed ground which, being softer, permits it to run deeper than the latter wheel, and hence the machine will run level when it would not were the wheels of A pair of longitudinal hound-bars 8 are let into the upper sides of the front and rear cross-bars 2 and 3 and are disposed parallel to each other, said houndbars extending at their front ends beyond the cross-bar 2 and being bolted to both crossbars in a convenient manner.

Located between the front ends of the hound-bars 8 is a draft tongue 9, said tongue being provided at its rear extremity with a beveled tenon 10. The draft bar is pivoted by a bolt 11 between the front ends of the hound-bars, and between the rear end of the draft-bar or tongue and the front cross-bar 2 a space intervenes. In this space there is mounted for sliding between the hound-bars 8 a locking-block 12, and the same hasits opposite sides grooved to receive the houndbars, which latter form ways for the block. The fronty face of the block is vertically recessed, as at 13, and the bottom of this recess is provided with a series of inclined teeth or notches 14. By drawing the block back and adjusting the draft-tongue t0 a proper point, that is, depressing or elevating as may be desired, the front end of the frame, and sliding the block forward so that one of its teeth or notches engages with the tenon of the tongue, it will be seen that said tongue becomes locked in relative position or at a relative angle with the frame. It may be secured in this position through the instrumentality, in the present `instance, of one or more binding bolts passed through either or both ofthe Ahound-bars and binding upon the block. In

this'manner, as will hereinafter appear, the plows are given a proper inclination and may be made to run shallow or deep, as desired.

Passing through the two side-.bars l immediately in rear of the cross-bar 2 is a transverse rod 15, and at intervals there is located and pivoted upon the rod cast-metal blocks 16 whose front ends are reduced and perforated to receive the rod and whose rear portions are bifurcated to embrace the front ends of the series of plow-beams 17. The plowbeams 17, at their rear ends are fitted with cast-metal caps 18 bifnrcated to embrace the ends of the beams and are also'beveled at their rear ends, as shown, and are adapted to rest upon a transverse rest-bar 19 which is secured to the inner face of the rear cross-bar 3 and is reduced from its upper end to its lower edge.

Each of the plow-beams is provided with vdepending standards 2O suitably braced, and

the said standards are arranged in adiagonal IOO series extending from the right-hand front corner to the left-hand rear corner of the frame. To each standardthere may be vsecured any suitable plow, but l prefer to secure thereto and employ a plow 2l, the-con struction of which is covered by a companion application concurrently pending and bear ing Serial No. 469,594, and which was filed April 8, 1893. A pair of standards 22 rise from the side-bars l near the rear ends of the latter and they support a cross-piece or bar 23 at the center of which is located a seat 24 for the accommodation of the driver. A series of inclined rods 25 extend from the crossbar 23 to the rest-bar 19 and are spaced apart so as to form guides for they plow-beams and as a means for supporting them in relative position or parallel to each other. Between the pairs of rods 25 there are pivoted to the rear side of the cross-bar 23 hooks 26 which may be employed for suspending any one or all of the plows with their rear ends elevated and their plows out of Contact with the soil. A pair of end standards 27 rise from the rear corners of the frame and are connected to the standards 22 by horizontal guide-rods 28. A vibrating transverse-bar 29 is perforated at its ends and mounted upon and supported by the rods 28 and its forward movement is limited to spacing sleeves 3() also located upon the rods and interposed between the'bars 29 and the standards 22. The transverse bar 29 in line with the beams is provided with a series of openings 3l, and said openings are also in line with the recesses 32 formed in the inner side of the rear cross-bar 3 immediately above the rest-bar 19. In each of these recesses 32 there is located a spring-lever 33 whose upper end extends through the opening 3l in the bail 29Vin which it is adapted to vibrate, being considerably smaller than the opening and is provided near its lower end with a shoulder 34, abrupt upon its under side and inclined upon its upper side. When the plow-beams are depressed or in their lowered position and resting upon the rest-bar 19, it will be seen that the shoulders take over the rear ends of said beams and hold them in depressed positions, and hence their plows are operatively in contact with the ground. It will be seen that any one of the plows may be liberated from engagement with its spring lever by a simple rearward drawing of the upper end of the lever so as to disen gage the shoulder of the lever from the beam. In this manner. any one of the plows may be liberated together with its beam so as tov pass over an obstruction lying in its path and may be supported by means of its hook in such elevated position. By withdrawing the hook, however, the plow will fall, and the rear beveled end of the beam readily ride over the beveled shoulder to resume its position upon the rest-bar and be locked by the lever. The hand lever 35 is fulcrumed at its lower end to the rest-bar 3, as indicated at 36, immediately in rear of the bar 29, and

ing-over any obstructions that may lie in the path of the machine. A transverse yoke-bar 38 is arranged above the series of plow beams in advance of the cross-bar 23, and the same is connected. at intervals by short chains 3 9 to the plow beams. From the center of this yoke-bar 38 a lever 40 extends rearward between convenient giiide-rods 25 andV tothe rear of the machine where it is provided with a hook 4l which, when the lever is depressed and the yoke-bar elevated, may be engaged with a suitable stud 42 extending from the rear side ofthe bar 3. The lever is fuicrumed upon the underside ofthe cross-bar 23 through the medium of a couple of links 43. It will be observed that by first a pull upon the hand-lever 35which liberates all of the plow beams the lever 40 may be depressed and the entire series elevated and locked in such elevated position by the hook and stud described. In this manner the machine is adapted for traveling to and from the field of operation or for passing over obstructions that niaylie in the path of the gang of plows. If obstructions lie solely in the path of one or two plows the spring levers may be operated individuallyv and also the beams whose plows are thus exposed elevated individually and supported by the supporting-hooks in such position until the danger has been avoided.

I do not limit my invention to the particular details of construction herein shown and described and hold that I may vary the saine to any degree and extent within the knowledge of the skilled mechanic without departing from the spirit or sacrificing any of the advantages thereof.
