This invention pertains to plowing or furrowing devices, and more particularly to that type of devices to be used `in subsoiling.
On plantations or farms of various kinds,
` it is often desirable or necessary to subsoil during the growth of various crops. For instance, on sugar and pineapple plantations, it is very necessary that'subsoiling be ef'-y fected between the various rows of the crop at different periods of 'their growth. -Heretofore it has been necessary toy employ a single subsoiler drawn by mules and worked by two men, for performing this operation,
which of course, it will be appreciated, is
more or less ineffective vas well as costly as not`only is it slow vbut a single subsoiling operation is not effective as a sufficient depth is oftentimes not reached. With the f machines in use, subsoiling points are attached to the machine and the machine is pulled reither by tractor power or by mules, which is also unsatisfactory such a machine itself cannot be heavy enough for' the points to penetrate a suflic'ient distance,
and then too, the machine cannot be ac.
curately guided unless anotherl man is employed, so that here again the cost of -operachine capable of more extensive operation and one which may be easily controlled at -a singlev oint vby a single person.
A furt er object is to 'provide controls for the operating means of a subsoiler Whichare positive, areof small number and so disposed" as to be capable of operation from a f single source.
With these and various'other objects in view, the invention consists of certain novel features of construction and voperation as charactersare used to designate like partswill more fully described and particularly pointed out in the specification, drawings` and claims appended hereto.
In-the drawings, wherein like reference v 5 Flgure 1 1s a lslde elevation of the subsoiling device as applied to atractor, the tractor being indicated generally in dotted lines; F1gure2 is an end elevation of-the device 60 v shown in Figure 1, showing-the points in subsoiling operation; and
Figure 3 is a fragmentary end elevation of the bracket attachmentbetween the yoke and the tractor frame, the same being taken 55 substantially in the plane as indicated by the line 3--3 of.' Figure 1.
vIt will of course be c appreciated that thouglnthis device is described as lapplied to a tractor that it mayjust as readily be ap- 70 plied. to an other vehiclecapable of this use, and w ile subsoiling points are particularly referred-to, it lwillbe understood that .these points may include disc or mold board plows or harrows, etc., as well as specific subsoiling points.
Tractor 10 is provided on either side thereof with a frame 11 to which may be attached at any convenient point a bracket assembly 12.- Said assembly consists essen- 30 tially of a pair of bracket plates 13 and 14 provided with'adjustable pin holes 15, said .bracket being braced to the tractor by means of fore and aftbraces 16 and transverse' braces 17. An arm 18 is pivoted 35 to the bracket assembly by means of the bolts 19 disposed in any of the selected pm holes 15. r'lfhe other end ofthe arm 18 is bracketed or secured by means of the connecting plates or brackets 20 and 21 to the 90 upper and lower subsoiling arms 22 and 23 which may conveniently be in the form of yokes. Said yokes' are secured together at their central portions and embrace opposite sides of the arm' 18. The arms are pro- 95 vided with bolt holes 25 adapted to'provide adjustable securing means for the subsoiling points 26 fastenedto'said yokes by means of clamps 27 and bolts 28.
In lthe present disclosure the subsoiling v i' arms 22 and 23 are constructed in the form of a' yoke for the purpose 'of arching the central portions thereof upwardly out of the path of the growing crops. The machine, as shown, arches the rows of'crops and presents the subsoiling points for work -in the aisles between the rows; thef arched construction l of thelyokesl provides clearance, .eliminating by the yoke.
danger of contact and damage to the crops As alread explained, the subsoiler arms are in the orm of-yokes, the same being bent upwardly at the center thereof and so disposed as to have'contactino',relation with l'peach other, though it will zbey'appreciated that should the subsoiler arms be adapted only for plow orharrow use, the same may be substantially ystraight across and properly provided with the disc or barrow polnts along the length of the arms. For manipu-J lation of said yokes, a framelift or hoist 29 is provided which consists essentially 4of upright members 30 secured-to the tractor body, l
anda ytransverse member 31 bracketed tothe upright members by means of brackets 32. A'jack shaft 33 is driven from themotor or engine through gear box 34, the end of said shaft being suitably mounted in bearings 35 supported 5y the bracket assembly 36. Said jack shaft carries a'windlass or.
- drum 37 loosely mounted thereon for rotary movement 'and conveniently disposed with reference to the hoist frame29. Between one end of the drum 37 and the jack shaft, there is disposed any suitable clutch means 38 for the purpose of selectively .establishing connection between said shaft and said drum. A'pawl Iand ratchet 39 and 40 are provided at the other :end` of said drum normally in engagement .for preventing the' drum from revolving. The pawl is operated by means of a releasepedal 41 convenientlg 'disposed with respect to the drivers seat` said pedal being pivoted to the tractor at43 and,connected to the pawl by means of a link 44. A clutch lever 45 pivotedvto. the frame at anchor plate 46 is provided with a thrust collar 47 preferably encircling the jack shaft and adapted to move the clutch elements through engagementwith a proper clutch collar (not numbered), said lever bem connected/to a clutch lever handle 48 `sultably pivoted at 49 for operation'from the drivers seat 42, said lever 48 being connected tothe clutch lever by means of the. link 5,0. The -clutch lever handle is con- -nected by means of an. adjustableflink 51 to one arm of a bellcrank or automatic release arm 52, said releasearm being pivoted .to the uprights lat 53 and4 havingv a contractile spring 54 connectedv to said uprights and to the other arm of the release arm so that the action of the spring will normally cause disengagement between the clutch elements and l.the drum, .Y
The tractor is provided with a guard 554 so disposed with reference to the yokes asto prevent said'yokes from interfering with proper operation of the tractor or the devices disposed thereon. A block and tackle 56'is .70
disposed between the 'yokes and .the upper frame member. 31 of the hoist frame 29, the sheaves 57 and'58 being releasably connected tothe yokes and frame member 31 by means of linksC 59 and 60. The ro e of the block and tackle assembly runs rom the upper sheave blockthrou h guide rollers 61 down to and around the rum 37 in such a manner that the pawl and rachet 39 and 40 normally prevent rotation of said drum. Holding uprights 30 and are ofsuitable length and provided with hooks 63 for the Apurpose of engagementwith the yokes to hold the same in raised position, forming-a further supporting means for .said .yokes to thereby re'A lieve .the tackle of the straincaused by the weight of the yokes and points.
yokes pivoting around the polnt 19 on the frame 11.v W en the yokes have been raised to the. desired lheight, thehandle 48 may-be released and the spring 54 will render the clutch inoperative with respect to the drum, the pawl and ratchet 39 and v40 maintaining the vdrum 'in fixed position, locking the yokes in a raised .position where it will be underf stood the Jhooks 63 may then be attached to the yokes, forming a further support-for with the shaft causing the block and tackle 1 y the same. When it is desired to lower the yokes', it will of course he appreciated that not wish to be limited by the exact embodiizo,
.though it is appreciated of course that 1121275 It'will of coursebe understood that I doY Y* ment of the device shown as other and va- `rious Aembodiments will of course occur to those skilled in 'the art.
. I claim: 5 1. Ina device of the character described the combination of a vehicle, a frame pivf otally attached to saidvehicle at substantially *thel mid-point of. its length, said frame comprising a pair of side arms and a lo cross arm connecting the ends of said side arms,'said crossv arm being located in close proximityv to the end of said vehicle and means 'mounted .at the lend -of said vehicle and connected to said frame or raisin' and 15` lowering said frame, 'said cross arm eing arched throughout its central portion.
