Patented Nov. 11, lfi t UNETEQ STATES GEORGE A. GHENT, OF B'UHL, IDAHO.
CORRUGATOR.
Application filed. January 31, 1924. Serial No. 689,779.
50 all whom it may concern: I
Be it known that I, Gnoncn A. GHENT, a citizen of the United States, residing at Buhl, in the county of Twin Falls and State of Idaho, have invented certain new and useful Improvements in Corrugators, of which the following is a specification, reference being had to the accompanying drawings.
This invention relates to corrugators and more particularly to an improved structure of this sort having novel and improved means for adjusting the shovels with relation to the frame so as to move them into and out of engagement with the round.
An important object or the invention is to provide a device of this character having means for preventing side sway of the shovels when the same are elevated from the ground.
A further object of the invention is to provide a device of this character in which the adjustment of the shovels is accom plished by the axle without elevating the frame or any other portion of the device than the shovels and the beams thereof so that the energy employed is reduced to the lowest possible extent.
A further ob ect of the invention is to provide a device of this character so constructed that all of the work being done, controlling a team and properly guiding the corrugations, lies in front of the operator so that it may be readily observed.
A further object of the invention is to provide a device of this character in which the shovelsare arranged as approximate the center in turning as is possible so that it is unnecessary to remove the shovels from the ground in turning and the drag ordinarily present during such turning operation when the shovels are engaged in the ground is prevented.
A further object of the invention is to provide a device of this character which may be cheaply and readily constructed and which will be durable and efficient in service.
These and other objects I attain by the construction shown in the accompanying drawings, wherein for the purpose of illustration is shown a preferred embodiment of my invention and wherein Figure 1 is a plan view of a corrugator constructed in accordance with my inv-ene tion, an adjusted position of the beams be ing indicated in dotted lines;
Figure 2 is a longitudinal seotiollitl view through the apparatus on the line 2-2 of Figure 1 Figure 3 is a section on the line 33 of Figure 1, the shovel beams being shown in partially engaged position in solid lines and in disengaged position in dotted lines;
Figure 4: is a detail view showing the mounting of the wheel upon the axle;
Figure 5 is a detail sectional View showing the connection between the beams and cranks;
Figure 6 is a perspective of the auxiliary shovel; Y
Figure Tis a perspective of an alternative formof front shovel.
Referring now more particularly to the drawings, the numeral 10 indicates a beam the forward end of which forms a tongue 11 andthe rear end of which, indicated at 12, forms the center beam of a frame 13. In addition to the portion 12 of the beam 10, the frame consists. of a pair of flat relatively heavy strap metal bars 14 bolted at their forward ends to the beam 10 as indicated at 15. From the point of attachment to the beam these bars diverge rearwardly rather sharply to form the front of the frame and then continue in parallel relation to form the sides of the frame. I
At the forward ends of the sides of the frame a bolt 16 connects the bars 14: extending through each thereof and into a notch 17 formed on the under surface of the beam 10. This bolt 16 between the bars ll is provided with a sleeve formed in three sections 18 and 19, there being two of the sections 19. The section 18 is of a length equal to the width of the beam and is secured against movement upon the bolt 16 i and with relation to the bar 10 by a strap 20 secured to the under surface of the section 12 0f the beam 10 at opposite sides of the bolt and engaging against the sleeve. The forward end of this strap 20 is bent downwardly a short distance and then extends forwardly parallel to the frame as indicated at 21. This portion 21 has an opening receiving the lower end of a clevis bolt or pin-22 extending through the beam 10. The numeral 23 designates an axle having in its ends wheel receiving portions 24 and an intermediate portion 25 axially aligned with these wheel receiving portions. Intermediate the wheel receiving portions andthe central portion 25 the axle is formed with throws or cranks 26, the purpose of which will presently 33B.
p ear. The ends 2a are directed through the frame bars 14 and suitable openings formed therein, the mounting being such that the axle is rotatable.
The central portion is engaged in a bearing 27 secured to the under surface of the portion 12 of the beam 10. Any desired type of supporting wheels 28 maybe employed, those illustrated in the present instance being provided with the dust proof hub connection 29 desirous in agricultural machinery. Straddling the axle at one side of the beam 10 is a segment 30 the other surface of which is upon an are having the axle as its center. The axle at the same side of the frame is provided with an integrally secured lug 81 to which is secured a lever 32 operating adjacent the segment and provided with a spring-pressed dog 33 coacting with the notches thereof and disengageable by operation of the handle portion S-El 'arranged adjacent the free end of the lever. Upon the upper surface of the beam 12 rearwardly of the axle is secured a drivers seat through its support 34.
The sleeve sections 19 extend entirely through the distance between the ends of the sleeve portions 18 and the corresponding side of the frame and to these sleeves are secured beams 35. These beams are preferably formed by employing a single strip of metal and bending the same back upon itself to thus provide a slotted member, this slotted member being at the bight portion thereof and for a short distance from this bight portion relatively straight and. then being arcuately curved as indicated at 36, this curvature extending to the lower or shovel end of the beam. The means of attaching the beam to the'sleeves preferably consists of a strap extending about the sleeve and having its ends abutting opposite faces of the beam, a bolt extending through-the slot 37 of the beam and through these ends to secure the strap,which is indicated at 38, to the beam. As a means for preventing movement of the strap 38 longitudinally of the beam a set screw 39extends through the strap to engage the sleeve. Since the sleeve is rotatable upon the bolt 16, it will be seen capable of rotation withthe sleeve as a center but is held in adjusted longitudinal position upon this sleeve. lVhile I have described but one beam and sleevit will is seen that there are at least two of these beams, the beams corresponding in number and arrangement to the cranks 26 of the axle and being arranged at opposite sides of the main beam 10. The numeral it designates a spacing bar formed from flat metal and provided with a central up-bowed portion 41 overlying the frame beam 10. At opposite sides of this bowed portion the strap in its end portions is provided with a series of transversely spaced openings 42 that the beam is adapted for interchangeable reception of a securing element 43 which extends through the slot 37 of the corresponding shovel beam and has upon its lower end a nut abutting a clamping plate 44 upon the under surface of the beam. it will be seen that this device affords means for regulating the spacing of the shovel beams rearwardly of the point of pivot thereof and since they are secured against movement in adjusted positions upon the pivots thereof these beams will remain in adjusted relation and cannot sway from side to side with relation to one another. To prevent swaying of the beams from side to side in unison I secure to the side members l i of the frame upstanding abutment members i6 aligned with the ends of the spacing member 10 and against which these ends loosely operate. By these abutment members any marked degree of sway of the shovels when disengaged with the ground is pre vented. Directed through the slot of each shovel beam rearwardly of the spacer isa U-bolt 1-7, the ends of the arms of which have plates 48 thereon slidably abutting the under surface of the beam. These U bolts straddle the crank portions 26 of the shaft.
It will be seen that upon operationof the lever 32 the axle is rotated and this rotation will cause the crank portions 26 to approach or recede from the ground dependent upon its direction. These cranks being connected with the beams will cause the lower ends thereof to be elevated or depressed, the U-bolt connection compensating for the necessary shift of the point of connection between the shovel beam and crank. By this form of construction it is possible that the shovel carried by the beam be arranged directly below the axle so that any tendency of the shovel to lift is resisted by the entire weight of the frame and at the same time the action of the shovels can be readily observed. To the lower end of each beam will be secured a front shovel 49 and a rear or auxiliary shovel 50, both of the shovels being sccnred to the beam by securing elements directed threugl'i the slot 37 thereof. The front shovel may be of any desired or usual type and is readily interchangeable. I have illustrated upon the oeam a front shovel of one type and in l iguro 7 a shovel which may be substituted for the shovel upon the bean if so desired. The rear shovel preferably 601% sists of a body ll-shaped .1 cross section, the ends of the V flaring outv ardly to provide cutting edges for cleaning sod and grass from the edge of the corrugations. This rear shovel is preferably secured to the beam at its lower end upon a transverse pivot mounted in the beam at its lower extremity and at its upper end by a plate secured to the beam and arranged in the general plane of the beam havingan arcuate end, the curvature of this arcuate end being with the pivot 51 as a center. lhe sides or mold-board sections 52 of the rear shovel are connected at their upper end by a transverse bar 53 having an opening therein through which is directed a securing element 54: interchangeably engageable in openings 55 spaced longitudinally of the arcuate portion of the attaching bar. While I have particularly described a preferred form of this shovel, it will be understood that I do not wish to be limited to such specific structure except as hereinafter claimed.
