DOUBLE DISK 'HAnRoW.

Specification of Letters Patent.

Application filed July 9, 1914. Serial No. 849,866.

To all whom z'zfmay concern Be it 'known that I, \VILLIAM W. CAME- RON, a resident of La Crosse, in the county of La Crosse and State of Wisconsin, have invented certain new and useful Improve- "ments in Double Disk Harrows, of which crating metal.

the following is a full, clear, and exact de scription.

The invention relates to disk harrows and more particularly to that type which comprises plural members connected to travel in tandem relation, or onebehind the other. One object of the invention is to' provide an improved harrow of this type in which all of the members are shiftableinto and .out of operative position by a. common lever, Another object of the invention isatoprovide an improved harrow of this type in which a generalframe to which all of the members are connected is dispense with,

' the draft and shifting connections between -..-the barrows serving to maintain them in proper relative position. A still further object of the invention is to provide a harrow of this type in which a frame and-oparts may be formed of wrought till further objects of theinvention are to provide an improved construction of reach, an improved mounting for the shiftinglever, brace-connections between the reach and the transverse draft-bar at the front of the machine, and improved draftconnections between'the front and rear harrows. Other objects of the invention will appear from the detail description. I

The invention consists in the several novel features of construction hereinafter set forth and more particularly defined by claims at the conclusion hereof.

. In the drawingsz'l igure 1 is a plan of a harrow embodying the invention. Fig. 2 is a side-elevation Fig. 3 is a section taken on line 33 of Figtyll Fig. 4 is a perspective {of the draftbar and its connections, the frames of the front harrow being also sh'own.

--1'Them'achine comprises a front harrow 1510 composed oftwo members or sections 11, andarear' harrow'l2 also composed elf members or sections 14. Each member of the front and rear harrows comprises a shaft 15,

Patented Apr. 17, 191'7.-

a gang of disks 1(5 scrapers 16? and spacing Y spools 17 between the disks, all of which may be ofus'ual construction, as well understood in the art.

A transversely extending draft-bar 18-is dispdsed forwardly of the front harrow and draft is applied thereto by means of links 19 and a clevis is usually connected by a chain to a tractor. Each link 19 has an eye- 20 at its rear end which is connected to a loop 21 whichis pivoted to one end of the cross bar 18 by a bolt 22.

A bearing 24 is mounted upon one of the spools 17 adjacent the inner end of each gang of the front harrow 10, and abearing 25 is mounted at the side of each of said gangs on one of said spools. A standard 26 j is secured to each bearing 24% and a standard 27 to each bearing 25, and an angle iron cross-bar 28 connects the standards of each member 11 of the front harrow. Additionalbearings 24 and 25- inay, if desired, be secured to said cross-bars. These standards and cross-bars serve as frames for the memconnected to one of the frame-bars 28'by a bolt 35 which passes through a strip 33 which-is rigidly secured to bar 28. Each lower draft-bar or brace extends downwardly and rearwardly from bar 18 and is pivotally connected by a bolt 31 to lugs 29 'on bearing 25. Filler blocks v32 are placed inside of the angle-bar 18 for convenience in attachment of the parts thereto. Draftbraces 30 and 34 in extending downwardly and upwardly from the draft-bar 18 ap'ply the powerat a point substantially on a level with the bearings and at a point above the bearing to'theframe-bar 28, thus forming a braced longitudinally extending draft-connection between the draft-bar18 and the members of the flout harrow respectively' Pivot bolts 35 and 31 are vertically alined 56 and so that each harrow section may be adjusted horizontally to the aft and whereby said ends may be secured in.

fixed relation to the draft-bar. This mechanism comprises a hand-lever 36 which extends between the dual members or bars 37 of a reach 38 and is pivoted thereto by a bolt 39 which is disposed forwardly of the draft bar 18. The lower end of lever 36 is connected to each of the members of the front barrow by a connection comprising a link 40 pivoted to the lower end of lever 36 by a bolt 41 and having its rear end pivoted to the bearing 24 by a bolt 42.

A brace. olti 4A and extends upwardly and rearwaroly and is pivotally connected by a bolt 47 to a strip which is secured on one of the frame bars 28. These links and braces between the. lever and the inner members of the front harrow form a substantial braced draft connection for the inner ends of the members of the front harrow. A stop-plate adjustably secured to bar 18 serves to hold down links 40 and the inner ends of the front barrow members.

Beach 38 is secured to the draft bar 18 by a standard formed of angular brackets 18 having their upper ends disposed between the members 37 of the reach, and a bolt 49 extending through the upper ends of said brackets and the reach-bars. tions of brackets 48 are secured to draftbar 18 by bolts 50. The front end of the reach is secured to each side of bar 18 by

braces

51 and 52 extending forwardly and inwardly from the top and front of the frame bar respectively. The front ends of these braces and the reach 38 are secured together by a. bolt 52". This manner of construction provides a well-braced connection between the reach and draft bar. A segmental rack 54 has legs disposed between the reaclrbars and is secured thereto by bolts Spacing blocks 57 are held between the legs 55 of the rack bar and one of the reach-bars 38 to space said members apart so that the lever 36 will be free to be shifted between said members. A lock bolt 58. operated by a finger-lever 59, is adapted to engage the notches in rack 54' to lock the lever and its connections in desired positions. This manner of constructing the reach and disposing the angling lever and rack effectively supporting these )arts.

When the lever 36 is shifted orwardly,

43 is secured to each link 40 by a The lower porbraces 43 and links 40 will be shifted rearwardly to cause the members of the front harrow to be angled horizontally, each section swinging about an axis formed by bolts 31, 35 thereon.

The rear harrow is connected to the shifting mechanism so that its members will be horizontally angled into forwardly convergent relation, oppositely front members, which will be angled into rearwardly convergent relation, and lever 36 serves to conjointly shift the members of the front and rear barrows. Each rear member is provided with an outer bearing 63, an inner bearing 64, a standard (i5 secured to bearing 63, a standard 66 secured to the bearing 64 and an angular cross bar 67 which is rigidly secured to the upper ends of the standards. Additional bearings 63' and 6* are secured to cross-bars 67. An angular plate or bar 68 is interposed between the inner ends of cross bars 67 and is connected to the inner ends of said bars respectively, by a bolt and slot connection 69. The disks of the. rear members are faced to throw the soil inwardly when angled, and bar 68 serves particularly, when engaged by the reach-extension, to hold down the inner ends of the rear lrarrowanembers, and also serves to support the reach-bar. These slot-connections permit the bar to accommodate itself to different positions as the rear gangs are angled.

with respect to the p Lon'gitudinally extending draft connec- Y tlons are provided between the inner sides of the rear sections and of the front sections. Each of these connections comprises a bar or link 70 which has its front end pivotally connected by a bolt 71 to the rear end of strip 33 which is fixed on front cross bar 28, and its rear end connected by a bolt- 72 to a strip 73 secured on frame-barfi'i'. Each of these connections also comprises an arched bar 74 which has its central portion secured to bar 70 by bolts 75, its front end pivoted to a bearing 25 by a bolt 76, and its rear end pivoted to a bearing 63 by a bolt 77. These braces for these draft connections avoid the necessity of. using direct links at the level of the bearings.

Bolts

71, 76 are vertically alined, and

bolts

72, 77 are also alincd vertically so that the rear sections can swing horizontally. The connection for shifting and drawing the inner ends of the rear sections comprises a link 78, the front end of. which is pivoted, as at 79, to the operating lever 36, and this reach extends between the reach-bars. The rear ends of bar 78 is connectcd by braces 80 to a yoke 81, the side arms of which have their rear ends pivotally connected to bearings 64, respectively, by bolts 82. The longitudinally extending drafbconncctions between the sides of the members are rearwardly divergent, as illustrated in Fig. 1. The disks of the members of the rear harrow have their inner faces concaved so thatwhen they are in operative position the soil will exert an outward pressure upon these members. Resultantly, the divergent longitudinal draft-connections for the rear harrow exert in a degree an outward pull upon the front harrow members which have their disks faced so that they will be crowded together by the soil when in operation. By arranging the longitudinal connections to exert an outward pull upon theof reach 38, by bolts 85 and spacing Washers 85. The rear portions of the bars of reachextension. 84 are spaced apart, as at 86, to receive the front end of a traction bar extending to the implement to be drawn in the rear of the harrow. A-Joop 87r-hasgitsssidee armslsecured-toplate 68 by bolts 88 audits crossmember overlies the reach to permit limited horizontal and vertical movement of the rear end of the reach.

The invention thus exemplifies a machine comprising front and rear barrows, each comprising a pair of pivoted members, and in which the front harrow-members may be operated into rearwardly convergent rela tion and the rear harrow members operated into forwardly convergent relation by a common lever which is pivoted in front of the front harrow. The invention also exemplifies a tandem barrow in which the longitudinal rearwardly divergent draft-com neotions are pivoted to the members. The angling lever and look therefor are sustained by a braced structure in front of the draftbar. The construction throughout is one which may be made of wrought metal and all of the parts ane substantially constructed and well braced. so that the implement is well adapted to be operated by a tractor.

The invention is not to be understood as restricted to the details set forth, since these may be modified within the scope of the appended claims without departing from the front and rear harrows,
