United States Patent 3,477,149 SNOW PLOW MOLDBOARD WITH RESILIENT SCRAPING BLADE Charles H. Wagner, 4920 10th Ave. S., Minneapolis, Minn. 55417 Filed Dec. 7, 1967, Ser. No. 688,865 Int. Cl. E01h /06; A01b 15/00; E02f 3/76 U.S. CI. 3750 3 Claims ABSTRACT OF THE DISCLOSURE A road clearing blade to be carried on the moldboard of a snow plow being wedge-shaped in horizontal section formed of a tough hardened rubber-like abrasive resistant material being sufficiently resilient to resist nicking and breaking and having wear resistant inserts for bottom surface reinforcement.
Background and summary of the invention The conventional metal snow plowing blade carried on a moldboard is subject to damage by engagement with curbs and with hard ice projections. The ground engaging edge of a metal blade wears down rather rapidly requiring frequent replacement of the blade. It is desirable to have a blade having the effectiveness of the rigidity of a metal blade but having longer lasting usefulness.
With respect to the related patented subject matter known to the inventor, the U.S. Letters Patent No. 3,028,-
692 to Brock shows a rubber moldboard sandwiched for support between a pair of rigid strip members and having a scraping edge and extending beyond said strips to form protective ends. Here the moldboard is formed of a combination of hard and relatively soft rubber. The U.S. Letters Patent No. 2,061,585 to Meyer shows the use of a relatively soft rubber strip for clearing slush from a surface. The U.S. Letters Patent No. 3,090,140 to Trane shows a flexible strip having a rigid backing or supporting member, and U.S. Letters Patent No. 3,126,- 652 to Reissinger shows a slush clearing appliance formed of old rubber tires underlying a moldboard.
The construction and particular configuration of the invention herein is clearly distinguishable from the above art.
It is an object of this invention to provide a scraping blade to be carried on a moldboard and being formed of a tough rubber-like material having sufficient rigidity for snow and ice scraping or clearing purposes, being sufiiciently yielding to resist nicking and breaking and having wear resistant reinforcing members in its ground engaging surface.
It is another object of this invention to provide a rubber-like scraping blade such as of polyurethane of sufiicient hardness and having vertically disposed reinforcing members disposed therein integral therewith to provide stiffness and wear resistance to said blade.
These and other objects and advantages of the invention will be set forth in the following description made in connection with the accompanying drawings in which like reference characters refer to similar parts throughout the several views and in which:
FIG. 1 is a view in perspective showing the invention in operating position;
FIG. 2 is a view in vertical section on a somewhat enlarged scale taken on line 2-2 of FIG. 1 as indicated;
FIG. 3 is a view of the invention in front elevation;
FIG. 4 is a bottom plan view of the invention; and
FIG. 5 is a view in vertical section on an enlarged scale taken on line 5--5 of FIG. 3 as indicated.
3,477,149 Patented Nov. 11, 1969 ice Description of a preferred embodiment Referring to the drawings, a conventional type of moldboard for a snow plow such as of a road clearing apparatus is indicated generally by the reference numeral 10. Supporting members 12 are indicated by which said moldboard will be mounted onto or carried by an appropriate vehicle.
The invention herein indicated generally by the reference numeral 15 comprises a scraping blade to be used in connection with said moldboard.
Said blade 15 is in the form of an elongated plate member rectangular in elevation as shown in FIG. 3, and being substantially rectangular in vertical cross section. Said blade in the embodiment disclosed is wedgeshaped in horizontal section tapering from the end portion 17 to the end portion 18. Said thicker end portion 17 is the curb end of the blade and the end portion 18 is the end portion of the blade which will travel remote from the curb. The moldboard and said blade thereon will be biased or angled with respect to the direction of travel with said end portion 18 being the forward or leading end portion. The snow gathered will accumulate along the blade increasing in volume or mass in the direction of said curb end portion 17 of said blade. Hence said end portion 17 is the heavier and sturdier end of said blade.
For the purpose of stiffening said blade and increasing the wear resistance of its ground engaging surface 19, a plurality of reinforcing members 21 are centrally vertically disposed and imbedded or molded within said end portion 17 to be integral with said blade and to be coplanar with its bottom ground engaging surface. Said reinforcing members will be spaced longitudinally of said 'blade. It is within the inventive concept herein to have them spaced along the full length of said blade. Said reinforcing members are here indicated as being formed of steel cable but may be formed of any suitable rod members having a high degree of resistance to abrasion or wear.
A plurality of spaced transverse slots 25 are formed through said blade allowing for height adjustment with respect to the bolts 26 disposed therethrough and through aligned apertures in said moldboard to secure said blade in operating position.
As to the specific composition of said blade, an essential element of the invention herein lies in providing a non-metallic scraping blade formed of a material having superior qualities to metal in having greater resistance to wear and to nicking and breaking, and to be free from being permanently deformed as by bending especially along the scraping edge. A very suitable rubber-like material has been found in polyurethane rubber of appropriate hardness which is very satisfactory when on the order Durometer. The design of the blade places its greatest stiffness in the area handling the greatest work load and thereby reducing the bulk of the blade along its length. Polyurethane rubber molded of polyurethane resins provides a material of great strength and toughness having high abrasive resistance and sufficient resilience to be resistant to chipping or nicking and breaking of the scraping edge.
As shown, said blade is mounted onto the forward face of the moldboard with its lower or scraping edge being positioned to be somewhat below the bottom edge of said moldboard.
Thus it is seen that there has been provided a simply constructed scraping blade having superior use characteristic with respect to a conventional commercially used metallic scraping blade.
It will of course be understood that various changes may be made in the form, details, arrangement and proportions of the parts, without departing from the scope of the invention herein which, generally stated, consists in a device capable of carrying out the objects above set forth, in the parts and combinations of parts disclosed and defined in the appended claims.
What is claimed is: 1. A snow clearing blade in connection with a moldboard carried by a snow plowing vehicle comprising an elongated plate-like member having a length substantially the length of said moldboard being substantially rectangular in vertical sec-tion and tapering in thickness from the curb end of said blade to the other end thereof, said blade being formed of a relatively hard rubberlike material having high abrasive resistance and sufiicient resilience to be resistant to nicking and breaking, a plurality of elongated wear resistant reinforcing members disposed within said blade to be coplanar with the bottom surface thereof, and means mounting said blade on the forward surface of said moldboard.
