SNOWPLOIV AND DISTRIBUTING ATTACHMENT FOR ROAD-$CRAPING MACHINES.
Application filed March 25, 1925. Serial No. 18,145.
This invention relates to snow plow attachments for road scraping or grading machines, whereby the standard road scraper may be converted into a highly efficient snow plow and snow distributor.
The greatest objection-to snow plows used on rural roads is that the snow is banked up on the sides of the roads, forming walls of considerable height before the winter is over. Falling snow, drifts between these walls, often collecting to a considerable depth. When the road is again plowed, much difficulty is, of course, encountered, going through these drifts and again turning ofl the snow to the sides of the road. Moreover, the walls at each side of the road increase in width each time the road is plowed, consequently narrowing the driving space of the road.
It is the main object of this invention to provide an attachment for a road scraping machine which will permit the snow to be plowed by the usual road scraping blade and distributed over the shoulder of the road or in the ditch atone side of the road where it will not bank and form theobjectionable walls at the sides ofthe road. The attachment is also well adapted for distributing sand, dirt and gravel on the shoulder of the road.
It is a further object of the invention to provide an auxiliary blade adapted to overhang the shoulder of a road and to receive the snow from adiagonally disposed road scraping blade and distribute the same over the shoulder of the road and in the ditch adjacent thereto. The snow is thus not only removed from the road but spread out where it will more quickly be melted and evaporated.
It is a further object of the invention to provide an outwardly extending auxiliary blade secured to one end of the road scraping blade having its bottom edge disposed some distance above the bottom edge of the road scraping blade.
A still further object of the invention is to provide means rigidly secured to one of the back wheels of the machine, or the side of the frame, to prevent lateral skidding of the machine due to the side pres sure exerted by the auxiliary blade in plowing and distributing the snow. The co-operation of this non-skidding means is found necessary to efficiently plow and distribute the snow as desired.
It is 3'111016 specific object of the invention to provide in such a device a pivoted means connected to its outer end, and pro- H vided with means for raising or lowering said blade to. a desired position.
A still further object of the invention is'to provide a snow plow and distributing attachment for standard road scraping machines capable of being'secured to function at either side of the scraper blade.
These and other objects of the invention will be apparent from the following description made in connection with the accompanying drawings, wherein like notations refer to similar parts throughout the several views, and in which Fig. .1 is a cross section through the front portion of a standard road scraping machine having the preferred form ofthe inventionmounted thereon, showing most of the parts in elevation;
Fig. 2 is a plan view of the device mounted on a road scraping machine with some parts of the machine being broken away;
Fig. 3 is a rear elevation of the auxiliary blade attached to the blade of the scraping machine;
Fig. 4 isan enlarged fragmentary rear elevation of the attaching means for said blades with some parts detached;
Fig. 5 is a vertical section taken on the line 5-5 of Fig. 4;
Fig. 6 is a side elevation of the non-skidding runner rigidly secured to one of the back wheels of the scraping machine;
Fig. 7 is a vertical section taken on the line 7.7 of Fig. 6, and
Figure 8 is a detailed view showing the means for quickly elevating the auxiliary blade to prevent interference thereof with obstacles on the road.
In Figs. 1 and 2 astandard road scraping machine is illustrated having the main frame 8 mounted on the front and rear wheels 9 and 10 respectively, the sub-frame 11 extending from the front of the machine to approximately the central portion thereof below frame 8 and carrying the ring or circle 12 on which the semi-annular member 13 is slidably mounted, constituting a turn table for supporting a scraper blade 14. The blade 14: is secured to the turn-table 13 by means of the depending arms 15, and is usually of suflicient length to traverse the distance between the outer sides of the back wheels, preferably having a concave front side. The usual sharpened cutting edge 14 is secured to the bottom edge of the blade 14. Operating wheels 16 engaging suitable mechanism for raising or lowering the two ends of the blade 14 and thereby varying the angle of said blade, are mounted on the rear portion of the main frame 8. The turntable is supported from the sub-frame 11. The rear axle housing 17 is secured to the rear ends of the main frame 8 and the front truck is pivoted to the main frame by the king bolt 18.
The invention in its preferred form comprises several co-operating devices adapted to be readily attached to the standard road scraping machine. An elongated auxiliary blade 19 of approximately the same length and thickness as the scraping blade 14 is provided having the centrally projected apertured tongues 19 at either end thereof, the lower portions of the ends of the blade proper extending at right angles to the bot tom of the blade and affording the square shoulders 19, the purpose of which will later be explained The end portions of the blade 19, above the tongues 19*. are cut on an oblique line affording the oblique shoulders 19, extending inwardly somewhat with respect to the square shoulders 19*. A cutting edge 20 is secured to the bottom edge of the blade 19 at the front side thereof. having its ends spaced slightly from the shoulders 19 of said blade. The scraping blade 14 is provided at its end portions with three vertically spaced apertures therethrough. and channeled plates 22 having the lower square shoulders 22 and the upper oblique shoulders 22", are provided, also carr ing the central bosses 23 and having the three vertically spaced apertures therethrough in alinement with the apertures in the ends of scraping blade 14. The apertures in the tongues 19 of the auxiliary blade 19 are of slightly greater size than the boss 23 so that the blades may be pivoted together about the boss 23 and secured within the channel plate 22 by means of the outer plates 24 bolted through the channel plates 22 to the scraping blade 14. by means of the transverse nutted bolts 21. the central one of which passes through the boss 22. The tongue 19 is thus pivotally secured to the blade 14 and will be free for swinging movement in substantially a vertical plane within the limits of the shoulders 22 and 22".. It will be noticed that a portion of the auxiliary blade 19 overlaps the end of the scraping blade 14 and that at the end of the cutting edge 20 abuts the end of the blade 14 when the auxiliary blade is lowered to approximately horizontal position. The shoulder 19 abuts the shoulder 22 of the plate 22 at that time,
thereby co-operating to limit the downward position of the auxiliary blade. The upper shoulder 19 of the blade 19 being set slight- 1y back permits the auxiliary blade to be swung upwardly until the top edge of the tongue 19 contacts against the angular shoulder 22 of the channel plate 22. It is obvious that the auxiliary blade 19 may be similarly mounted at either end of the scraping lade 14. always being attached to the rear end of blade 14 when the same is diagonally disposed with reference to the longitudinal center of the frame. The attachment is only operative when the scraping blade is disposed in a transverse diagonal position.
The outer plates 24 have slots adjacent their ends and a central aperture so that the blades when pivotally connected may be readily detached by taking out the central bolt and simply loosening the upper and lower bolts.
A flexible member 25 is secured at one end to the top intermediate portion of the blade 19 and passes over the sheave 26, having its other end made fast to the operating lever 27 located adjacent the drivers platform on the machine. the position of blade 19 and may be quickly manipulated to raise the free end of said blade as desired.
A transverse arm comprising two angularly extending members 28 and 29, is secured across the sub-frame 11 of the machine forwardly of the blades. The lower member 28 is bent upwardly at a point beyond the outer side of frame 11, while the upper member 29 is bent upwardly from a line across the inner side of the same portion of frame 11, said members 28 and 29 being clamped together between the sides of frame 11 and also at a point adjacent their outer extremities. A wedge block 29 is driven between the angle formed by members 28 and 29 at a point directly over one side of the frame 11 traversing the arm and being secured to frame 11 by means of bolts at either side of said arm. A depending loop or hook 30 is secured to the outer end of the members 28 and 29, through which a flexible member 31 is passed having one of its ends secured to the free end of the blade 19 through the aperture in the tongue 19 and having its other end preferably secured to the king bolt 18 on the front truckof the machine.
In order to furnish an efficient base of resistance for the work done by the auxiliary blade projecting from one side of the machine. a non-skidding runner is provided rigidly secured to one of the rear wheels 10, preferably the rear wheel on the opposite side of the machine from the auxiliary blade 19. This runner comprises a relatively thick horizontal body portion 32 having an outwardly curved sharpened cutting edge 33 The lever 27 thus controls secured to the bottom edge thereof and adapted to cut into the snow, ice or ground and prevent the back rtion of the machine from skidding laterall y f due to the resistance of the snow against the auxiliary blade. Obviously, the auxiliary blade disposed Wholly on one side of the machine and adapted to overhan the shoulder of the road, must have a rm'base of resistance. Such a runner has been found to bethe only means whereby-the back portion of the machine will be prevented from any skidding. The runner is preferably secured to the wheel 10 by means of a plurality of hooks 34 having their outer ends threaded and bolted against the outer side of the body portion 32. The runner is further secured and braced bymeans of the diagonal brace bar 35, best shown in Fig. 7 the inner end of which is secured to the rear axle housing 17. The guard chain 36 connects the front .end of the runner with the main frame 8.
It is obvious that, as has been stated, the auxiliary blade as well as the runner and arm for receiving the draft means, may be disposed on the opposite sides of the machine, thereby reversing the entire attachment. This is desirable oftentimes when one side of the blade 14 or blade 19 becomes worn. In order to reverse the attachment, the scraping blade 14 must, of course, first be swung on the turn-table to the opposite diagonal position with reference to the longitudinal center line of the machine.
The operation of the device is probably obvious but may be briefly summarized as follows:
The auxiliary blade is preferably lowered to a substantial horizontal position and the machine pulled along the side of the road with the auxiliary blade overhanging the shoulder of the road and the ditch at the side thereof. The scraping blade 14 will cut the ice and snow and plow the same, pushing the plowed snow outwardly and backwardly to the auxiliary blade. The auxiliary blade will spread the show out and distribute the same over the shoulder and ditch of the road, thereby entirely removing the snow from the travelled portion of the road and preventing a ridge of snow from accumulating at the sides.
The auxiliary blade 19 is so pivoted to the scraping blade 14 that the bottom edge of blade 19, when in horizontal position, will extend at a considerably higher level than the cutting edge of blade 14, preferably four or five inches thereabove. The purpose of this construction is to enable the auxiliary blade to pass freely over any ice. or crust adjacent the outer end of the scraping blade, thereby not disturbing the crust or cutting into the snow but merely pushing the plowed snow backwardly and outwardly and distributing the same into the ditch at the side of the road and over the shoulders of the road. The raisedlevel of the auxiliary blade therefore lessens the resistance of the snow thereon and permits the snow'to-be distributed and spread out evenly due to the receiving shoulder of the road.
The draft device for the outer end of the auxiliary blade properly holds said blade in operative position, while the lever 27 permits the blade 19 to be quickly raised as desired. p
From the above description, it will be seen that an extremely simple but highly efficient attachment has been invented fora standard road scraping machine capable of being readily attached or detached. Extensive actual usage of the device has shown the same to be highly successful for the purposes intended including the distribution of gravel, sand and dirt.
It will, of course, be understood that various changes may be made in the form, details, proportions and arrangement of parts without departing from the scope of the invention, and that the device may be equally well applied to other types of grading or road-working machines than the type illustrated in the accompanying drawings.
