Abstract
ABSTRACT
This invention, which I call an Operator Propelled Rotary Garden Tiller relates to a manually operated garden tillage tool, for light garden tillage and weed eradication. The usual, or conventional methods have been the use of horse drawn cultivators which often result in a trampling down of tender young plants, and is otherwise impractical in a smaller garden where space is limited and the rows are short. In re-cent years gasoline powered tillers have been placed on the market, while practical, the increasing cost of fossil fuels has been rising steadily, and are now becoming scarce. Gas-oline powered tillers are inclined to be noisy, are air pol-luting, also bulky and rather heavy to handle and not suitable for closely spaced rows, and in such cases the old fashioned hoe must be resorted to. The purpose of the Operator Propelled Rotary Garden Tiller is to achieve, with the least possible expenditure of energy the maximum amount of tillage, that is, to soften up the soil to provide a mulching effect between the vegetable rows and to eradicate the weeds by the rotary action of the tines of the Operator Propelled Rotary Garden Tiller.

Description
SPECIFIC~rIONS
This invention relatss to a light-weight, operator propelled roSary garden tillage tool for the gardensr with a ~mall garden or ¢lossly spaced rows of ~egetable~ for the purposes of light tillage Qnd weed control.
In this inventlon, ths cultivator whan pushsd by the oper-ator, thru thd ~o~vard motion rotatss the propalling wheel freelg on an axle ~et in a frame, held securely in place by bra¢ket3 attachsd to a tubular frame with handles and having a rotating tillin~ attachm~nt diractly behind the propellin~
lOS4841 1~. wheel and tilling atta~hment. ~hile consideration was givsn to the u~e of Q chain and sprocket3 in place o~ a V-belt and pulley~ to dri~e the tllling ~ectio~, it was fslt that V-belts and pulley~ would be lighter, efficient and ~omewhat cheaper to manuracture than ¢hains and sprocket~. ~he main consider-ation, however being to provide a tiller ~or the small garden or closel~ spaced row~ at minimum expense.
The tiller shart is seoured in nylon or other bearings bolt-ed to an ad~ustable mounting bracket 3eourely welded to the frame allowing ~or variabls tillage depths.
20, ~he light tiller tine~ being ad~u~table ~or tllling width as well as depth, turn as the tiller is propelled forward by the operator the turning motion of the propelling wheel thru the attaohed V-pulley and belt and V-pulley on the tiller ~haft rotating the tines and thru the forward motion of the tiller sradioating the weeds, mulching and sortening the 90il between the ro~s under cultivation.
While con~lderation was given to the use of a ~hri~k ~it rubber tire with lug3 to prevent e2ces~ive ~lippage o~ ths propelling wheel it was de¢ided that a molded wheel of light 30. weight plastics with the necessar~ lugs would be more sati~-factory.
The tubular frama should be light and sturdy, with welded 3teel ¢ro~ m~mbers, molded rubber handles, V-belt tightener, and adjustable 3tsel mounting bracket welded ~e¢urelg to the f~a~Q~Tine~ 3hould be o~ rea~onable width of light but ~trong steel with chi~el t~e edge~ ~or eaay tilling.

~ 'he rotary-tiller, a manually operated garden tiller for light weeding and tillage between closely spaced rows and use in a small garden comprised basically of a propel-ling wheel set in a frame with handles, a tilling section with rotating tines, secured to a mounting bracket, welded to the frame, and rotated by the rolling action of the pro-pelling wheel thru the use of v-pulleys on the propelling wheel and tiller shaft the forward motion of the tiller when pushed by the operator rotates the tiller shaft and tines in a forward direction thru the energy transmitted thru the use of a v-belt passing around the propelling wheel v-pulley and the tilling section v-pulley thus breaking up and tilling the soil. Provision is made for tilling width and depth.
Reference may be made to the drawings in which the various component parts making up the tiller are as follows Propelling wheel 1, provided with lugs 24, a v-pulley 5, a part of said wheel, or keyed to the said wheel thru a keyway 38, turning freely on an axle 3, passing thru brackets 7, one on each side secured to a tubular frame 2, by the bolts 8. The axle 3, being secured on both ends by the key 12, or if preferred, the axle 3, may be threaded on both ends and heagonal nuts with washers used to secure the shaft within the frame.
The frame 2, of comfortable length, having two handles 22, with rubber hand grips 21, on the handles separated and reinforced by a tubular cross member 13, welded at the ends to the inner sides of the tubular frame 2, in, a suitable distance from the ends of the handles 22. the forward end of the frame 2. being carried by the axle 3. of the propel-ling _ 4 _ wheel.
A second cross member 14, angular or L shaped, beingspaced rearward of the propelling wheel l, and welded to the inner faces of the frame 2, at the proper distance from the propelling wheel l, and having centrally located and pro-truding downward a tiller mounting bracket 15, tubular and retangular with regularly spaced holes matching holes in tiller section mounting 28, and of suitable length with holes thru the forward and rear sides of the said bracket 15, which is welded at the upper extremity to the cross member 14, which member constitutes a part of the frame 2, and carries and secures the tilling section mounting 28, which is freely adjustable in the mounting bracket 15, and secured by the bolt 30.
The tines 27, of which there may be two or three pairs on either side of the v-pulley 20, may be adjusted for till-ing width on the shaft 18, by the pins 36, being inserted thru the holes 35, in the tilling assembly shaft 18, which in in turn passed thru the bearings23, bolted to the mount-ing bracket 28, fitting inside of bracket 15, and secured by the bolt 30, passing thru parts 15, and 28.
A belt 29, of the V type is passed around the v-pulley 5, and in turn passed around the v-pulley 20, so that when the tiller is pushed forward by the operator, the rolling action of the propelling wheel tUrnsthe v-pulley 5, which in tu~n rotates the v-pulley 20, secured to the shaft 18, by a pin 36, rotating the tines 27, and tilling the soil.
Tension on the belt is maintained thru means of a belt tight-ener or idler puller 31, mounted on a slotted and ajustable bracket 32, secured to the frame 2, by the bolt 33, having washers 34, on either side of the idler, or tightener pul-ley 31, which 11~54841 is secured by a bolt or pin to the adjustable bracket 32, the braoket bein~ ad~ustable upwards or downwards to 130. obtain the dssirad tension on the V-balt 29.
Having desoribsd tin the foregoing 3pecifications and draw-ln~s ths relation of the various part~ of the tilleraa~ a whole, I requsst that a Letters Patent be granted.
