EDWARD H. SHOLAR AND WALTER W. PAGE, OF CHATTANOOGA, TENNESSEE, AS- SIGNORS TO THE VOLUNTEER DISC PLOW 00., OF GEA'ITA'NOOGA, TENNESSEE.

DISK PLOW.

To all whom it may concern:

Be it known that we, EDWARD H. SHOLAR and lVALTER XV. PACE, citizens of the United States, residing at Chattanooga, in the county of Hamilton and State of Tennessee, have invented a new and useful Disk Plow, of which the following is a specification.

The general object of the present invention is to provide a disk plow of extremely simple and inexpensive construction, in which all unnecessary parts are eliminated, and in which the necessary adjustments are effected by mechanism of very simple character and maximum efficiency. Subordinate to these general objects are certain specific objects, the most prominent of which are First, to provide a novel disk mounting which will enable the disk to be turned more or less to the land, or in other words, adjusted as to its horizontal angle to the line of draft, which will also enable the disk to be adjusted toward and from the perpendicular plane, and at the same time either elevated or depressed relative to the beam, according to the character of the soil being worked, and which will also enable the disk to be vertically adjusted without a change of either its horizontal or vertical angle. So far as this feature is concerned, the present application is a division of the co-pending application, Serial No. 328,645, filed July 31, 1906.

Second to provide novel means for mount ing the scraper so that said scraper is readily adjustable to properly cooperate with the disk no matter in what relation the latter is positioned.

Third, to provide means whereby a plurality of beams or beam sections may be secured together to provide a gang plow, the different sections or members being readily interchangeable.

An embodiment of the invention that is at present considered the preferable one is illustrated in the accompanying drawings, wherein Figure 1 is a plan view of the plow. Fig. 2 is a side elevation of the same. Fig. 3 is a sectional view of the disk and its mounting. Fig. 4 is a similar view with the parts adjusted to present the disk in a more nearly perpendicular plane and with said disk slightly elevated. Fig. 5 is also a sectional view showing the parts adjusted to likewise Specification of Letters Patent.

Application filed August 15, 1907.

Serial No. 388,673.

present the disk in a more nearly perpendicular position to slightly depress it. Fig. 6 is a modified form of disk mounting simplified, but having somewhat less range of adjustment. Fig. 7 is a view of another modification, showing a still simpler disk mounting. Figs. 8, 9, 10 and 11 are still further modifications of the mounting for the disk. Fig. 12 is a detail sectional view showing the adjustable mounting for the scraper, said mounting being illustrated in elevation. Fig. 13 is a sectional view therethrough. Fig. 14 is a detail sectional view on the line 1 1-14 of Fig. 13. Fig. 15 is a horizontal sectional view through the coupling between the beam members, or sections. Fig. 16 is a bottom plan view of the same.

Similar reference numerals designate corresponding parts in all the figures of the drawings.

In the embodiment illustrated, the frame of the plow consists of beam members or sections 17 having front and rear end portions 18 and 19 disposed in obtuse angular relation to their middle portions. The front end portions 18 are preferably disposed in alinement, as illustrated in Fig. 1, and the beam sections or members are connected by a coupling 20. As shown particularly in Figs. 1, 15, and 16, this coupling consists of a cap plate 21 having depending flanges 22 and 23, the flanges being located inside the margins of the cap plate and disposed in angular relation. The flange 23 moreover consists of angularly disposed portions, as shown. The flange 22 is disposed alongside the front portion 18 of the rear beam section or member, and is secured thereto by bolts 2% that pass through said flange, and through openings 25 in the beam member. A sufficient number of openings is provided to per mit the adjustment of said beam member, as will be evident by reference to Fig. 15. The other flange 23 is located alongside the intermediate portion 17 of the front beam, and the adjacent portion of the rear end 19 of said beam, and clamping bolts 26 are passed through the beam and flange. Thus, the beam sections or members are effectively secured together, but they may be separated, and single plows formed therefrom, as will be evident. Moreover while two members are illustrated in the present embodiment, it

will be evident that any desired number may be employed.

Secured to the front end 18 of the front beam member or section is a bracket 27 formed with an upright guide 28 and a beveled segment 29. The guide is vertically movable upon a post 30 supported by a front furrow wheel- 31 in any suitable manner. Fulcrumed upon the lower portion of the segment 29 is a front frame adjusting lever 32 having an angularly disposed forwardly extending end or arm 33 connected to the post 30 by a link 34. The lever may be swung in an obvious manner to adjust the front end of the frame vertically, and is retained in its adjusted positions by the usual spring latch arranged to engage the segment.

A rear bracket 36 is bolted to and extends beyond the rear end of the rear beam mem ber 17, and is provided at its ends with a vertically disposed bearing sleeve 37 and a seat spring socket 38. The sleeve 37 constitutes a bearing for the vertically disposed journal 39 of a trailing crank axle 40, on which is journaled a rear furrow wheel 41. A latch 42, mounted on the bracket and operated by a conveniently located treadle 43, serves to normally lock the axle against its swinging movement. This mechanism, however, constitutes the subject-matter of the copending application, to which reference has already been made, and needs no detailed description. A seatspring 44 has its lower end located in the seat 38, and secured by a bolt 45, and a seat 46 is mounted on the upper end of the spring.

To the central portion of the rear beam member or section is bolted a land wheel bracket 47 in which is journaled the swing ing axle 48 of a land wheel 49. This axle is adjusted with respect to the frame by a lever 50 secured to the axle and retained in its adjusted positions by the usual spring latch 51 engaging a toothed segment 52 fixed with respect to the bracket 47.

To the front end of the foremost beam section or member is bolted a draw-bar attaching plate 52 to which is pivotally connected, as indicated at 53, a draw-bar 54 by means of which the draft animals are hitched to the plow. It is desirable to dispose the draw-bar in various angular positions with respect to the line of draft, and for this purpose, the plate is provided with a series of bolt holes 55 designed to receive a holding bolt 56 extending through the bar 54. Said bar may therefore be swung upon its pivot, and secured in any desired position by the bolt 56.

The disks 57 are mounted on the rear portions of the beam members or sections, and as usual, are provided with spindles 58, which rotate in boxings 59 located at the lower ends of vertically disposed standards (30. Each standard is rotatable in a disk supporting bracket 61 secured, in a manner to be explained, to the rear portion 18 of each beam. The disk standard is provided with an angular upper end 62 and a threaded extremity 63, the angular portion being designed for the attachment of an arm 64 retained upon the standard by a nut 65 screwed upon the extremity 63 and bearing against a washer 66 interposed between the nut and angular portion. At a point opposite the arm 64, the bracket 61 is provided with a rigid lug G7, and through this lug and arm is passed an adjusting screw 68 equipped with nuts 69 which clamp the arm and lug, and prevent their relative movement, as clearly shown in Fig. 1. By turning the nuts 69 in the proper direction, the arm 64 may be moved toward or from the lug (37, thus rotating the standard 60 for the purpose of adjusting the angular relation of the disk with respect to the line of draft, or in other words, for the purpose of adjusting the disk to take more or less land. It will be noted that this character of adjusting means permits an exceedingly fine adjustment of the disk or a more extended adjustment thereof if desired. Moreover the disk adjusting means also constitutes retaining means for the disk, and it is therefore unnecessary to operate a separate locking device, in order to hold the disk after the adjusting mechanism has been operated to set the disk at the proper angle. In addition to this adjustment of the disk with respect to the line of draft, the mounting also comprehends means whereby the vertical inclination of the disk may be changed and said disk simultaneously raised or lowered, also means for adjusting the disk vertically without any change of its angular disposition either with respect to the grounds or to the line of draft.

In order to attain these ends, the disk supporting bracket 61 comprises three bracket sections or members 61 (31", and (31, normally occupying horizontally alined positions, as illustrated in Fig. 3 and retained in rigid relation with each other and with the beam by bolts 70 passed through slots 71 in the bracket members, and also through the rear portion 19 of the beam. The bolts are retained by nuts 72 screwed thereon and bearing against a rear side of the beam. The slots 71 are of sufficient extent to permit relative adjustment of the bracket members. The opposite sides of the central member 61 are reversely curved, as shown in Figs. 3 and 4, and engage the reversely curved adjacent faces of the members 61 and 61 it being understood that the disk standard 60 is journaled in the outer bracket member 61. The innermost bracket member 61 is located against the side of the beam, the contacting faces of these elements being disposed vertically. The various faces of the beam and bracket members are horizontally corrugated for the purpose of insuring their rigid engagement.

It is obvious that if it desired to adjust the disk vertically without changing its angle, it is merely necessary to loosen the bolts and adjust the entire disk supporting bracket as a unit with respect to the beam. If on the contrary, it is desired to shift the disk to a more nearly perpendicular position without depressing the same or with a slight elevation thereof, the desired end may be attained by loosening the bolt and elevating the outer bracket member 61 with respect to the central member 61", as shown in Fig. 4. If it is desired to adjustthe disk to a more nearly perpendicular po sition and to simultaneously depress the disk, for the purpose of deepening the cut, this may be done by adjusting the members (31 and 61" as a unit with reference to the innermost member 61 as disclosed in Fig. 5. It will thus be seen that the peculiar form of the disk mounting not only provides for a wide range of adjustments both as to the horizontal and vertical angles of the disk but that it also provides for exceedingly fine adjustments. The same is obtained by simple and durable mechanism so that the disk may be adjusted with absolute accuracy to whatever position is best adapted to the particular character of the soil being worked.

In Figs. t l1 inclusive, modified forms of the disk supporting bracket which fall within the scope of the invention are illustrated. For instance, in Fig. 6, the inner bracket is eliminated, and a member (31 is interposed between the beam and the member (51. In this form of the invention, the bracket is adjusted vertically on the beam, and the upper member 61 is adjusted in the manner shown in Figs. l and 5. In Fig. 7, the member 61 is directly opposed against the modified form of beam 18 the modification consisting in providing the beam with a curved face corresponding to the contacting curved face of the bracket member. In Fig. 8, a bracket member Gl similar to the member (31, but modified by reverscly curving its inner edge, is opposed to a modified form of beam 18 having a convexly curved face opposed to the curved face of the member (31 In Fig. 9, the bracket member (31 is o) )osed to a member 61 identical in construction with the member 61 shown in Fig. 3, but interposed directly between the beam and the member (31. In Fig. 10, the outer bracket section 61 is modified by inclining its inner face and by interposing between the said member and the beam, a member (31 having its inner face opposed to the beam and its outer face inclined in correspondence with the inner face of the member 61 In Fig. 11, the construction is the same as that shown in Fig. 2-3, except that the member (31 is integral with the beam. These seve 'al modified constructions of the disk mounting are capable of substitution, for that shown in Fig. 3, inasmuch as each possesses one or more of the novel characteristics of the construction first described, and which is perhaps the preferable form of mounting.

A scraper blade 73 cooperates with each disk, and in order that said blade will effectively perform its function, regardless of the adjustment of the disk, a mounting for the scraper having a wide range of adjustment is essential. This mounting is preferably constructed as follows. An upstanding bracket 74: has a lower offset end 75 bolted, as shown at 76 in a seat 77 formed on the outermost bracket member (31 and the upper end of the bracket 74 is provider with an offset horizontally disposed terminal 78. A convexed bearing head 79 is mounted on the horizontal terminal 78, and is provided with depending ribs 80 that embrace the same. A concaved bearing head 81 fits upon the head 79, and provided with a longitudinal slot A holding bolt 83, passing through the terminal 78, the head 79, and the slot 82 has a threaded upper end on which a nut 84 is screwed. Consequently when this nut is tightened, it will be evident that the head 82 will be held against movement, and in different positions while the bolt serves to secure all the parts to the bracket 'd. The concaved cap or head 81 is provided with an outstanding arm 85 terminating in an upright sleeve 86, and through this sleeve passes an upright stem 87 having the blade 73 secured to its lower end. A set screw 88, threaded through the sleeve, engages the stem, and serves to hold it against movement. This structure as will be evident permits an adjustment of the scraper blade so that it will properly coope'ate with the disk when the latter is adjusted to different various positions, as above described.

From the foregoing, it is thought that the construction, operation, and many advan tages of the herein described invention will be apparent to those skilled in the art, without further description, and it will be understood that various changes in the size, shape, proportion, and minor details of construction, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.
