As appears in solid lines in FIG. 19 a support wheel assembly 100 and a drag stake 120 are disposed in their respective forward transport position. Drag stake 120 is fixed to a rear end portion of chassis 12 by means of a mounting bracket 70. Specifically, bracket 70 comprises right and left opposed plates 71 and 72 having fir~t portions spaced apart and respectively embracing rearward portion o~ chassis 12 and being secured thereto by means of two bolts, as at 74, which extend through aligned sets of holes provided in the rear portion of the chassis 12 and plates 71 and 72. Bracket plates 71 and 72 are provided with a further set of holes 66 which align with a set of holes 62 located in drag stake to position drag stake 120 to a desired depth in the earth. Drag bar 120 is positioned at a desired length by inserting a locking device 67, such as a hitch pin, washer and hairpin, into the aligned set of holes in the let bracket plate 71, drag bar opening 68 and right bracket plate 72. A third set of holes 6~ is located in the lower forward section of bracket plates 71 and 72 wilich hold a lock device 62. Lock device 62, shown here as a hitch pin, washer and hairpin assembly, secures wheel axle 22 in either the forward transport position or the rearward working position and must be removed to allow wheel assembly 100 to pivot from one position to the other.
h'heel assembly 100 includes a pair of legs 124 and 126 embracing outer surfaces of channel members 14 and 16, a pair of wheels 128 being rotatably mounted free end portions of the legs for rotation about wheel axis 22 and a sliding collar bar . ~2~L5~3 140 joined at the central portion of the wheel axle 22 by weldments. Legs 124 and 126 embrace channel members 14 and 16 at a hitch pin assembly 130 which defines an axis about which wheel assembly 100 may be swung from a forward position disposing wheel assembly 100 and drag stake 120 in respective transport positions, as shown in solid lines in FIG. 1, to a rearward position disposing wheel assembly 100 and drag stake 120 in their respective working position, as illustrated in dashed lines in FIG. 1.
A more detailed description of the structure and operation of the present motor driven rotary device will now be made with reference to FIG. 2 which incorporates the same reference numerals as heretofore used increased by 100. As appears in FXG. 2, support wheel assembly 200 and drag stake 220 are disposed in their respective working positions. I~heel assembly 200 is a~tached to chassis 112 by means of a hitch pin assembly 230. Specifically, hitch pin assembly 230 comprises a rod 232 which extends through axially aligned sets of holes provided in each of channel members 114 and 116, two flat washers 117 and 1l8 located on the outer surfaces of the legs 124 and 126, and llair pin 238 which passes through a hole located in the rod 232. Hitch pin assembly 230 is located at the rear of chassis 112 and defines an axis about which wheel assembly 200 may be swung from a forward position disposing wheel assembly 200 and drag stake 220 in respective transport positions, to a rearward position disposing wl~eel assembly 200 and drag stake 220 in respective working positions.
~2fl~S9~3 Wheel assembly 20~ includes two Metal legs 224 and 226 extending from opposite channel members 114 and 116 respectively, attached to wheel axle 122 by weldments, and pair of wheels 228 being rotatably mounted to axle 122. Metal legs 224 and 226 extend downward from channel members 114 and 116 from hitch pin assembly connection~ 230 and 231. A sliding collar bar 240 projects centrally from weldments behind ~heel axle 122 to enclose drag stake 220 within a narrow rectanglar groove. Sliding collar bar 240 guides drag stake 220 into either the transport posi~ion or working position when wheel assembly 200 is shifted about pivot 230 such as by removing locking device 162. The interconnecting of drag stake 220 and wheel assembly 200 permits drag stake 220 and wheel assembly 200 to be moved into the desired position simultaneously without the removal or adjustment of separate nuts and pins.
Drag stake 220 comprises an elongate flat bar 223 having a series of holes 168 provided within the upper portion thereof and having a lower end 221 adapted to penetrate the ground. ~rag stake 220 is attached to the rear portion of chassis 112 by means of a bracket 170 which is affixed to the rear end portion of chassis 112 by bolts, as at 174. Drag stake 220 projects centrally between closely spaced portions of bracket plates 171 and 172, portions having cooperating parts fixed together through a firs~ opening 166, by which lock member 167 in the illustrated form of a hitch pin, washer and hairpin respectively, pass. Lock member 167 also forms the means for confining drag sta~e 220 betw~en plates 171 and 172.
First opening 166 provided in plates 171 ~nd 172 registers with ~5~
a selected one of stake holes 168 and lock member 167 through opening 166 and is received in selected hole 168 and secured into position to hold stake 220 in a selected position in an angle slightly off of vertical for entering the ground to a desired depth when stake 220 is in its working position. The position of stake 220 off of verti~al allows stake 220 to be self-cleaning. The angle of the stake is such that upon engaging the earth in its working position, the soil is pushed around the stake edges. No accumulation of soil occurs.
Another opening 160 is provided in plates 171 and 172 such that lock device 162, shown here as a hitch pin, washer and hairpin assembly, may be inserted to hold wheel axle 122 in either of the transport or working positions. When in the transport position, lock device 162 must be removed from plates 171 and 172 to allow the wheel assembly 200 to pivot about hitch pin assembly 230 into the working position. The necessity of reinserting lock device 162 to fix wneel assembly 200 in the working position is dependent upon operator preference and the working conditions. However, lock device 162 can be reinserted to hold wheel axle 122 in the rearward working position and prevent axle 122 from swinging into forward transport position. Lock dcvice 162 can be used to hold wheel axle 122 in the forward transport position when wheel assembly 200 is so disposed.
Referring once again to FIG. 1, a hole (not shown) is provided for in the top of bracket 70 into which lock device 62 may be inserted. ~ith lock device 62 out of opening 60, wheel assembly 120 can be swung between forward transport position ~2 ~ 3 and rearward working position to compensate for varying working conditions by lifting the backend of device lO off of the ground and in a flicking motion of the handle bars 50 alternate wheel assembly 100 between the two positions.
As illustrated in FIG. l, the motor driven rotary device 10 includes a rearwardly projecting handle 50 including a pair of legs 52 attached by bolts 54 to chassis channel members 14 and 16, respectively.
The operation of the motor driven rotary device is as follows. With wheels lO0 and drag stake 120, through interconnectiOn of sliding collar bar 140, being disposed in its forward position, shown in solid line in FIG. l, and with the power transmission between pulleys 36 and 34 being interupted~ power dr;ven rotary device 10 is ready to be transported since drag stake 120 and wheels 100 are then respectively in their raised and forward transport position.
Transporting of power driven rotary device is accomplished by pivoting device lO back on wheels 100, by pressing downward on handles 50 and then by pushing or pulling device to a desired work site.
The power driven rotary device is then readied for operation by removing lock pin 62. Rotary driven power device is then pushed forward by use of handles 50 which causes wheel assembly lO0 to pivot backwards at hitch pin 130, wherein wheel assembly lO0 and drag stake 120 are in their rearward working position, as illustrated in dashed lines in FIG. 1. Drive belt ~Z~5~ 3 36 is then tensioned by means not shown to establish a driving relationship between engine 30 and tines 44. If drag stake 120 has not penetrated the ground to the extent that wheels 100 rest upon the ground, the operator may effect such result by adjusting the vertical position of stake 120. Drag stake lock pin 67 is then replaced in its propor location. ~ock pin 62 may be replaced in bracket opening 60 if necessary.
rO again ready power driven rotary device for transport, the operator needs only remove lock pin 62 (if necessary). IYheel assembly 100 is then free to pivot about hitch pin 130 and the operator can easily place the device in its transport position by pulling on handles 50 toward himself. Once in its tranport position, wheel assembly 100 and axle 122 are held in place by reinserting lock pin 62.
As will be apparent to persons skilled in the art, various modifications, adaptations and variations of the foregoing specific disclosure can be made without departing from the teachings of this invention.
