JOHN ZAHIRNIAK, or wnsnrrnxa's TERRACING MACHINE Application filed'March 18, 19st s milajsgasa, v p
vention resides in the provision of a machine of this nature which is exceedingly simple in its construction, inexpensive to manufacture, strong and durable thoroughly eflicient and reliable in use and operation, and otherwise Well adapted to the purpose for which it is designed.
NVith the above and numerous other objects in view as will appear asthe-description proceeds, the invention resides in certain novel features of construction, and in the combination and arrangement of parts as will be hereinafter more fully described and claimed.
In the drawings:
Figure 1 is a perspective view of the machine embodying the features of my invention. 1 Figure 2 is a side elevation thereof. Figure 3 is another perspective view there of showing the rear wheels differently adjusted.
Figure ,4; isa top plan view thereof. Figure 5 is a perspective view of one of the axle crank shafts, and V I Figure 6 is a perspective view of the ring. Referring to the drawings in detail it will be seen that the letter F denotes generally aframe which includes a pair of spaced parallel side bars 5 connected by a cross bar 6 at their rear ends and having forward portions converging forwardly as is indicated at 7 and on the ends of which is secured a hear- 14 is fixed on the upper end of the rod 10 by having a pair of spaced ears 15 thereon be tweenwhi'chis a block 16. j A link 17 is piv otally'lse'cured to "this. block 16 and isadjusttably' andfpivotally secured to'acrank 18 on a crank shaft 19 which. is j ournalled in'the upperfend of a bracket '20 rising from'the frame portions '7 .f crank21 extends from the crank shaft 19 and 'a' coimecting rod 22 is engaged therewith and extends rearwardly and is pivotally engaged with an intermedi ate portion of a lever 28 "pivoted at one end as'at 24'.ont1ie rear portionof the frame F and. provided witha suitable detent structurefld cooperable with a notched segment 25 on the frameF."- j
Obviously by rocking the lever 23 the front end of the frame may'beraised and lowered as may be required. 1 V
A pain'off crankshafts 26] are f-rockabl'e across the rear portionof theframe in suitsmattering-s27 and have inner cranks 28' andbuter cranks29which' terminate 'in outwardly directedfs'pindles 3010 1) which are journalledrear wheels31f Levers 32are pivotally mounted as at 34L on the frame F and have link connections 36 with the'cranks 28 arid'are formed. with suitable detent struc tur'es 3 7 cooperating withn'otched segments 38.jfObviously these' levers 32lmay be indepen dently adjusted soas to raise and lower therear end of the r amea d to slant the same to either side as may be desired; 'Aseat 39 is suitably mounted on the rear end of the frafnef'so thattlie three: levers 23, 32"and 32 maybelacce's'sible for ready manipulation by a person onthe seat; p
' Theside bars '5. ..of the frame are formed of channelir'ons; Channel iron cross barsAO are 'fdis'posed in "spaced-relation across an intermediate portion of the frame. A ring 41 is. rotatable in thechannelsof the bars 5,5" and 50', i O'." Thi's ringis provided with open-1 ings'e3 toreceive a spring pressed 'pin Ac' extending through a'n opening in the rear bar and slid'abletlirougha suitable bracket 45 thereon so tliatthe ring maybe turned to different positions and held insuch different positions the pin'engaging inone of the openings 43.
A pair of bars are mounted in upright positions in the ring 41 being suitably braced as at 51 with respect to the rings and the lower ends of these bars merge into angular extensions 52 in the ends of which is rockable a rod 53 carried on a straight mold board 54 by suitable means 55. Arcuate brackets 56 project from the mold boards and have openings 57 therein so that bolts, pins or the like 58 may be engaged therein and through the 1 extensions 52 to hold the mold board at dif-" ferent angular positions Withrespect to the extensions 52.
A blade 59 is bolted as at 60 to extend below the bottom edge of the mold board 54:. In actual practice it has been found that oneof the special features of this machine is that the black land does not stick tothe mold board. I have constructed my mold-board perfectly strai ht andbent 'the'bottom just enough to make the blade which is fastened to the mold board cut the dirt. Thisterracing machine works somewhat on the order of a' grader. The numerous adjustments made possible by the ring and the mold board with 5 respect to its support and the further adjustment made possible by the three levers permit the machine to meet practically all known problems in terracing. i
It is thought that the construction, opera- Q tion, utility and advantages of thisfin'vention will now be quite apparent to those skilled in this art without any more detailed description thereof.
The present embodiment of the invention has been disclosed'in considerable detail mere- 'ly for the purposes of exemplification sincein actual practice it attains the features of advantage enumeratedas desirable in the statement of the invention and the above descrip- 40. tion.
It will be apparent that jehanges in the details of construction, andfin the combination and arrangementof parts may be resorted to without departing' from the spirit.
4 or scope of "the invention as hereinafter claimed or sacrificing any of its advantages.
Having thus described my invention, what I claim as new is:
A machineof the class describedincluding a frame formed of channel members, a ring rotatable in the channel members, a ground engaging element, means for mounting the ground engaging element on the ring, means for holding the ring in difierent adjusted 5,, positions, the means for supporting the element comprising a pair of bars fixed in an upright manner in the ring and depending therefrom, a rod extending through the lower ends of the bars, means for fixing the rod on the. element, brackets extending fromthe element and adjustable means engaging the brackets with the bars.
In testimony whereofI affix my signature.
JOHN ZAHIRNIAK.
