3 Claims. 1
The present invention relates to a scraper attachment for tractors with means whereby the scraper blade may be adjusted for scraping, bull dozing, terracing, and moving dirt or snow forward, rearward, or to the right or left.
Objects of the present invention are to provide a device of the character which is simple, easily operated, easily attached and detached and easily adjusted for the various operations and can be manufactured at low cost, and is strong, efficient and durable.
To these and other useful ends my invention consists of parts, combinations of parts or their equivalents and mode of operation, as hereinafter described and claimed and shown in the accompanying drawings in which:
Fig. 1 is a side elevational view of my device as attached to a conventional tractor with the blade in its lowered position and positioned substantially parallel to the ground and at right angle to the direction of travel.
Fig. 2 is a drawing illustrating the device as shown in Figure 1 but in a raised position.
Fig. 3 is a view similar to Figure '1 except that the scraper blade is positioned at an angle to the direction of travel and tilted for certain road work and moving the dirt or snow to the right.
Fig. 4 is a view similar to Figure 3 but with the blade positioned parallel to the road or ground surface.
Fig. 5 is a view similar to Figure 3 except with the blade considerably tilted for terracing.
Fig. 6 is a view similar to Figure 1 except with the blade reversed for bull dozer work.
Fig. 7 is a fractional enlarged sectional view of the rear end of the device illustrating the locking means for the blade bracket.
Fig. 8 is an enlarged sectional view of the device as viewed from line 8-8 of Figure 1.
Fig. 9 is an enlarged vertical sectional view of the rear end of a modification of my device illustrating a fraction only of the blade carrying bracket.
Fig. 10 is a view looking from lines Ill-l0 of Figure 9, the holding bracket forthe blade being omitted.
As thus illustrated the tractor is designated by reference character A the scraper blade including its holding bracket is designated by reference character B. The tractor 'is' provided with a power lift the ram of which (not shown) is generally positioned within the tractor frame It having ground wheels 9 and is connected to a transverse shaft II, the ends of which protrude and to which generally rearwardly extending arms l2l2 are secured, the free ends of these arms being connected to the draw bars Iii-l6 by means of rods l3l3 which are screw threaded into heads l4l4, see Figure 1, the heads being pivotally connected to the rear ends of arms I2 as at l5|5.
Generally thisconnection between members l4 and I2 is in the form of a universal joint so the lower ends of rods l3 may swing sidewise as well as forward and rearward for a purpose which is obvious. The threads of members !3 and [4 have considerable length so the right or left hand draw bars I6 may be at their rear ends raised or lowered independently. Draw bars l6 are pivotally connected to the opposite sides of the tractor as at ll.
Thus far I have shown and described a power lifting mechanism of a conventional tractor with means for adjusting therear ends of the draw bars vertically independently.
The main frame of my device in its entirety is designated by reference character C. Member C consists preferably of a tube 25, the forward end of which is preferably electric welded to a transverse tube 26. This transverse tube is preferably secured to tube 25 by means of braces 21-21 preferably by electric welding: the rear ends of members It are pivoted to the ends of member 26 as at 24. Vertically extending bars 2828 (see Figure 8) are pivoted at their lower ends around tube 26, and converge as illustrated in Figure 8 to a width suitable for pivotally receiving a forwardly extending link 29 which is pivoted to the tractor frame as at 30.
The rear end of link 29 is considerably higher than pivot 30 therefore as the power lift raises member 26 the upper end of bars 28 will swing forward. Tube 25 has secured to its upper edge a' plate 35 having a number of spaced holes 36. I provide a link 31 which is at its upper end secured to bars 28 by means of an eye bolt 38 as shown in Figure 8, and the other end of link 31 may be secured to any one of the openings 35, for raising and lowering the rear end of tube 25 relative to its front end.
Thus it will be seen that when the'po'wer lift acts to lift the device, the rear end of tube 25 will travel upward faster than the front end as clearly illustrated in Figures 1 and 2.
Referring now to Figure 7 I provide a plate 40 having rigidly therewith a downwardl projecting boss 4|, the ends of this plate for a considerable width being on a radius with member 41. This plate is secured to tube 25 by means of four posts 62- 12 and -43. Another plate 4 4 is provided having upwardly and overhanging members 45 adapted to loosely embrace member 40 and being pivotally mounted on member 4| as indicated.
1 provide a scraper plate 50 which is suitably mounted on brackets 5|, the brackets being secured to plate 44. At the bottom of members 5| I secure a bracket 52 having secured thereto a scraper blade 53. It will be understood that members 5| and 52 make up a. frame for the support of the scraper plate 56 and blade 53.
It will be seen that member 4| will act as a pivot mounting for member B. In order to provide free movement of member 44, I provide a bolt 54 and a washer 55, the bolt extending through member 4| and holding the washer freely against the lower side of member 44. Members 44 and 45 are provided with a series of registering holes 56 which are on a radius with member 4|, and member 45 is provided with front and rear centrally positioned holes 51 which will register with any one of holes 56. I provide a a locking pin 66 which is adapted to extend through holes 56 and 51 and also through holes in tube (see Figure 7 I provide a triangular plate 6| which is pivotally secured to pin 66 as at 62, member 6| being pivoted to member as at 63. The upper end of member 6| is pivotally secured to a rod 65 as at 65 the rod extending upwardly and forwardly and through the opening in eye bolt 38 and to within reach of the operator of the tractor. Thus generally if the operator wishes to change the transverse angle of member B a forward pull on rod 64 will release member B and then by moving the tractor forwardly or rearwardly the transverse angle of member B to the direction of travel may be changed and the position locked by pushing rearwardly on rod 66 when the openings 56 are in alignment with an opening 51. Clearly member B may be reversed and held in the position shown in Figure 6 for bull dozing or adjusted to any angle transverse to the direction of travel.
I will now describe the modification shown in Figures 9 and 10:
Member B is exactly like member B of the other figures and members and 4| are similar. I provide a tube 70 which is rotatably held on tube 25 by means of a collar ll. Plate 35 is secured to the top of tube 25 preferably somewhat forward of the position shown in the other figures or tube 25 may be lengthened for the purpose. A post 12 is secured to tube 10 near the front end thereof, another post 13 is secured to tube 25 directly in rear of member 35.
A transverse U-shaped member 14 is secured to the top of member 13, the flanges of member 14 having screw threaded therein bolts 15 with lock nuts 16. Thus by adjusting bolts 15 the upper end of member 12 may be moved to the right or left relative to member 13 and the transverse angle of member B adjusted accordingly. Thus without changing links l3 the angle of member B may be changed or the two adjustments may be used to bring about an extreme angle of adjustment.
In this modification preferably a plate 11 is secured to members 43 having a tube 18 into which pin 60 is slidably mounted. A post 19 is secured to tube 70 to which member 6| is pivotally mounted as at 63 so that the turning of member B on pivot 4| may be brought about very similar to this adjustment provided for in the other figures.
It will be seen that I have provided a Scraper attachment for tractors having the characteristics mentioned in the preamble of this specification; that I have provided a novel modification with means for angling the blades independent of the power lift connections; that the blades may be adjusted transversely by the operator of the tractor from his position on the seat and that the rear end of the main frame of the device is adjustable and raised more rapidly than th front. Thus it will be seen from the foregoing that I have provided a very simple easily understood and easily operated device.
Having thus shown and described my invention, I claim:
1. A snow and dirt moving device in combination with a tractor having a power lift, comprising rearwardly extending transversely spaced draw bars pivoted at their front ends to the tractor and .having operating connections to said power lift, a transversely positioned member having its ends pivoted to the rear ends of said draw bars, a longitudinally positioned tube having-its front end rigidly secured to said transverse member midway the ends thereof, forming a T-shaped frame, a generally vertically positioned post mounted at its lower end on the front end of said frame, a brace forming a connection between the upper end of said post and said longitudinally positioned tube a distance in rear of said transverse member, another post rigidly secured to said longitudinally positioned tube adjacent the rear end of said brace, another tube rotatably mounted on the longitudinally positioned tube with its front end adjacent the other post, a third post rigidly secured to the front end of said other tube, a connection between the upper ends of said other and third post having means for transversely adjustably securing the third post to the other posts to thereby determine the turned position of said other tube, a plate secured to the lower side of said other tube, another plate swively connected to the underside of said first plate, means whereby the other plate may be turned and locked to the first plate in predetermined positions, a bracket having a scraper blade and mounted on the under side of said other plate.
